Description

Title: Connection sets, building systems, building construction, facade structure, and methods

SUBJECT

The invention relates to a connection set for a building construction, and to a building system, a building construction, and a building method.

The invention further relates to a connection set for a facade structure, and to a facade building system, a facade structure, and a method for realizing a facade structure.

BACKGROUND

Building constructions such as balcony constructions are known in various forms. Such constructions often comprise a structural connection between a structural arm such as a cantilever or other girder on the one hand, and on the other hand a support construction of a building, such as a floor or a wall. The structural arm is then for instance associated with an overhanging facade element such as a balcony element, which can be loaded in various ways, including for instance by planting.

There is an ongoing need for improvements in such building constructions. Thus, often, an easier and/or faster building process is desired, or efforts are made towards better thermal and/or acoustic insulation between building elements. In current building techniques, such aims often work against each other. Stricter insulation requirements then lead for instance to a more complicated building process.

Further, facade structures are known in various forms. A facade structure can have one or more different functions, including protection of wall behind it and architectonic embellishment. Known facade structures comprise for example a facade slab, for instance of stone or concrete, which is attached to an upstanding wall. Known methods for realizing facade structures are made more difficult by mutually counteractive requirements and wishes. For instance, a requirement for accurate positioning of a facade slab often works at the expense of building speed and/or building ease. Further complications arise from ever stricter requirements in the area of thermal and/or acoustic insulation, for instance between an interior and an exterior of a building on which the facade structure is provided. Thus, there is a need for improvements in the field of facade structures.

SUMMARY

An object of the current invention is to be able to realize building constructions such as balcony constructions more easily and/or faster, in particular with good insulating properties, for instance in the construction of new houses and/or as a part of renovations, as for creating extra outside space and/or for durability and sustainability purposes.

According to an aspect, to this end, a connection set for a building construction is provided. The connection set comprises a box-shaped receiving element which is configured for therein receiving an end part of a structural arm. The box-shaped receiving element has a rear which is configured to be structurally connected with an upstanding wall of a building. The box-shaped receiving element further has a front located opposite the rear. Provided in the front is a first passage through which the structural arm can extend when the end part thereof has been received in the receiving element.

The connection set further comprises a setting means for setting a position of the received end part relative to the receiving element. The setting means can be provided in one or more of various possible forms, for instance inside and/or outside the receiving element, as is further explained elsewhere in this disclosure. The rear may be structurally connected with the upstanding wall in various ways, for instance via steel bolts, by anchoring, and/or by a curing of a structural material. Besides the rear, optionally one or more further sides may be connected with the upstanding wall. Alternatively or additionally, one or more sides of the receiving element may for instance be connected with a floor or a roof of the building.

Advantageously, the box-shaped receiving element may be connected with an inner skin of an outer wall of a building. The outer wall of a building usually consists of an inner skin and an outer skin, with insulating material arranged between them. The receiving element may be attached against the inner skin, in particular the rear of the receiving element may be attached against the inner skin of the outer wall of the building. The front of the receiving element can extend against or into, or even beyond, the outer skin of the outer wall. Preferably, the receiving element is between the inner skin and the outer skin of the outer wall of the building and, after attachment, is surrounded by insulating material. The depth of the receiving element, the distance between the rear and the front of the receiving element, is preferably equal to the thickness of the insulating material used, more preferably equal to the distance between the inner skin and the outer skin of the outer wall of the building.

The end part may thus be structurally connected with the building advantageously via the box-shaped receiving element. The construction of the building may thus be extended, whereby the thus connected structural arm can form an extension of the building construction. The structural arm then extends preferably at an angle, for instance substantially perpendicularly, relative to the upstanding wall. Thus, for instance, a balcony construction and/or other cantilever or girder construction, such as a bridge construction, can be realized, for instance comprising an overhanging facade element such as a balcony element. With such constructions, normally, relatively high loads can be transmitted, in contrast to some known constructions.

Due to the setting means provided, only a moderately accurate positioning of the receiving element relative to the building is required, while still a sufficiently accurate positioning of the structural arm relative to the building can be achieved. The building process can thereby be made easier and/or be accelerated compared to presently known building methods. Due to the setting means provided, the structural arm can be set in the proper position relative to the receiving element. Thus, the receiving element can be mounted to a wall of the building, and the precise positioning of the structural arm can be done by setting the arm relative to the receiving element. This in contrast to the known building methods, where the receiving element should be precisely positioned.

To enable the above-mentioned setting of the position using the setting means, the end part is preferably received in the receiving element with play, most preferably with play all around, more preferably with a space for setting that is more than the usual play. The receiving element and the end part may be dimensioned with respect to each other to make this possible, as is further explained elsewhere in this disclosure.

In presently known building methods, by contrast, such play is actually normally avoided, which makes setting impossible. The consequence is that strict requirements are to be met regarding the positioning of, for instance, a receiving element relative to a respective building and/or an end part relative to a respective structural arm, as a result of which the building process becomes relatively complex and slow. In the known building methods, the receiving element should be mounted very accurately, which requires a lot of time and skills on the part of the construction worker. In the known building methods, the end part of the structural arm is usually received in the receiving element with a proper fit, so that a, typically, form-closed connection comes about. While this provides for a proper transfer of force, it does not provide for any possibilities of setting, and also results in a cold bridge which leads to a decrease of the insulation value of the building as a whole.

When the end part has been received in the receiving element, the end part in the receiving element is surrounded by a setting space or clearance, being a space or clearance in which the end part can be set relative to the receiving element. The setting space is determined by the distance between the end part and the receiving element in the length direction and/or the width direction and/or the height direction of the receiving element. The setting space may correspond to play provided, but may also be greater than usual play. Due to the setting space, the end part, and hence the structural arm, can be set in the desired position relative to the receiving element. The desired position can be a desired height, a desired depth as well as a desired orientation or angle. The setting space is preferably between approximately 10 mm and approximately 50 mm, more preferably between approximately 10 mm and approximately 30 mm and is thus preferably considerably greater than the usual play. Advantageously, such ample setting space is provided in all directions of the receiving element. This allows the end part to be received in the receiving element relatively easily and fast.

When the end part has been received in the receiving element and the position thereof has been set as desired, the end part is preferably fixed in the receiving element, as is further explained elsewhere in this disclosure. With such fixation, advantageously, a strong and stable construction can be obtained after the aforementioned setting has been finished. The setting space present between the end part and the receiving element, for instance substantially all around the end part, can be wholly or partly filled up with fixation material, such as for instance cast concrete. Alternatively, as fixation material, also securing bolts, for instance set bolts, can be used. The receiving element and/or the end part may for instance be manufactured substantially of steel.

Preferably, the connection set comprises an insulant arranged in the box-shaped receiving element, for reducing transfer of heat and/or sound between the receiving element and the end part received therein. Advantageously, the insulation is arranged all around in the box-shaped receiving element, around the end part received therein. The setting space present between the end part and the receiving element, for instance substantially all around, being not at the structural arm, the end part, can be filled wholly or partly with insulating material. The setting space can be partly filled with fixation material, and may be partly filled with insulating material.

Thus, advantageously, improved insulating properties of the realized building construction can be obtained, while the above-mentioned advantages are preserved. In particular, thus a firm construction can be obtained which is free of a steel connection between inner skin and outer skin. Such a steel connection could otherwise transmit heat and vibrations, which is undesirable. In known constructions, normally, such a steel connection is still present, for instance via one or more steel bolts, due to which a cold bridge is formed and vibrations are transmitted, which is normally undesirable. In other words, when the connection set comprises the insulant mentioned, advantageously a thermal and/or acoustic interruption between inner skin and outer skin can be provided, in particular a substantially complete interruption, so that the building construction can be free of so-called thermal and/or acoustic bridges between inner skin and outer skin. In presently known structural connections, normally one or more of such bridges can be pointed out, even when nonetheless some insulating material has been used.

A thermal and or acoustic interruption generally comprises a strongly insulating material that has been arranged in such a way, in particular between conductive structural parts, that the transfer of heat and/or sound between an inner part and an outer part is counteracted to a great extent, for instance substantially in accordance with an insulation value elsewhere in the facade and/or substantially in accordance with a relevant insulation standard.

Optionally, the insulant is manufactured of a rubbery material.

The rubbery material is or contains, for example, neoprene.

Neoprene has as a special advantage that it can not only provide thermal and/or acoustic insulation but also a relatively even transfer of force between the respective construction parts, in particular in that tension can be exerted via the elastic material.

Optionally, the box-shaped receiving element has a substantially open top. Thus, an interior of the receiving element can be easily accessible from the top, for instance for arranging an internal setting means. Also, the end part can be arranged in the box-shaped receiving element along the top thereof.

Optionally, the first passage and the substantially open top are both part of a same continuous opening in the box-shaped receiving element.

In this way, the end part of the structural arm can be placed in the receiving element easily, for instance from above, so that the arm thereupon extends through the first passage.

Optionally the connection set further comprises a blocking element connectable with the receiving element, which is configured, when in connection with the receiving element, to counteract the end part moving via the top out of the receiving element.

Such a blocking element can be used with particular advantage in the case of a cantilever construction such as a balcony construction or other overhang, whereby the connected blocking element can help take up a moment. Moreover, with such a blocking element a bias can be created in an elastic insulant, such as neoprene, which may be arranged between the receiving element and/or the blocking element on the one hand and the end part on the other hand. Such bias can advantageously promote the transmission of relatively high dynamic loads as of balconies, in particular while at the same time acoustic and/or other vibrations are damped. The elastic insulant, which, prior to mounting, has for instance been overdimensioned with respect to the space available therefor, is for instance compressed by mounting the blocking element to the receiving element, so that a bias is applied.

The blocking element comprises for instance a cover which can be connected to the receiving element, for instance with a bolt connection.

Optionally, in the blocking element a second passage is provided for therethrough supplying into the receiving element a filler, such as a curable filler, such as for example cast concrete.

Thus the blocking element may already be arranged in an early stage, in particular prior to a possible fixing with curable filler of the end part.

Optionally, the first passage is provided substantially centrally in the front of the box-shaped receiving element.

The receiving element is hence particularly suitable for receiving an end part that is substantially symmetrically widened with respect to a part of the structural arm at the location of the first passage. Such an end part is for instance T-shaped, Y-shaped or anchor-shaped, as is further explained elsewhere in this disclosure.

Alternatively or additionally, the first passage may be provided off-centrally. Such a variant is for instance suitable for receiving of an L-shaped end part, although an L-shaped end part could also be used in combination with a central first passage. Optionally, the setting means comprises at least one setting element for use as internal spacer between a bottom and/or sidewall of the box-shaped receiving element and the received end part.

Such a setting element can provide a setting means in a compact and yet stable manner, and with little material use.

Optionally, the at least one setting element comprises at least one setting plate for use as spacer between a bottom of the box-shaped receiving element and a thereon-supported part of the received end part.

Such a setting plate, or plates, can provide a setting element in a user-friendly and effective manner. In a simple manner, a worker can then set the end part, and the structural arm connected therewith, in the desired position.

Alternatively or additionally, one or more other types of setting elements can be provided, for instance one or more setting bolts, for instance for adjustment relative to the bottom and/or one or more sidewalls of the receiving element.

Alternatively or additionally, with respect to the at least one setting element, the setting means can optionally comprise at least one external setting means for use as settable support construction for the structural arm outside, in particular at a distance from, the receiving element.

Such an external setting means may be particularly easily accessible. Due to advantageous lever action, moreover, the setting with an external setting means may require only relatively little force and can be carried out with particularly high precision.

The at least one external setting means may for instance be temporarily arranged for as long as the end part has not yet or not yet sufficiently been fixed in the receiving element, after which the external setting means can be removed. Possible examples of such an external support construction or of parts of such an external support construction include: a crane construction, a prop construction, a tackle, a jackscrew, a hydraulic actuator, and a pneumatic actuator.

Alternatively or additionally, with respect to the at least one setting element and/or the at least one external setting means, the setting means can comprise the structural arm with end part, the end part being dimensioned to be received with play in the box-shaped receiving element of the connection set, in particular while the structural arm extends through the first passage.

Owing to such play or setting clearance, which, as mentioned, is lacking in presently known building methods, a position of the received end part relative to the receiving element can be set by external actuation of the structural arm.

The play mentioned preferably concerns play all around, that is, such play that the end part, at least as to dimensions, is floatingly receivable in the receiving element.

It will be clear that the setting means can thus be provided in one or more of various possible forms, for instance inside and/or outside the receiving element. The concrete shape or shapes of the setting means, as will be clear, can be chosen depending on the specific conditions of the construction to be realized and/or preconditions of the building process.

Optionally, the receiving element at its rear is provided with at least one anchor for anchoring to the upstanding wall.

Such an anchor extends for instance from the rear into or up to a wall part or floor part of a building. Alternatively or additionally, the rear may for instance be couplable to an anchor element which has been arranged in the building construction beforehand.

With such an anchor, the receiving element can be particularly firmly retained in the building construction, also when via the received end part relatively high forces are exerted on the receiving element. According to a further aspect, a building system is provided. The building system comprises: a connection set as described herein; and a structural arm with an end part which is dimensioned to be received with play in the box-shaped receiving element of the connection set.

With the building system, above-mentioned advantages can be achieved. As mentioned before, the play can in particular make the setting of the position of the end part in the receiving element easier, whereby such setting makes a less accurate positioning of the connection set relative to the building allowable, so that the building process can be made easier and/or be accelerated.

As described hereinbefore, such a structural arm with end part can optionally wholly or partly form the setting means of the connection set, while alternatively or additionally one or more other setting means may be provided.

Preferably, the end part is provided with an insulant for reducing transfer of heat and/or sound between the receiving element and the end part received therein.

Such an insulant of the end part may for instance be provided as an addition or alternative to the above-mentioned insulant of the receiving element, with substantially corresponding advantages. What holds thus is that preferably at least one of the receiving element and the end part is provided with an insulant, in particular comprising a rubbery insulant such as neoprene.

Optionally, the end part is substantially hook-shaped, for instance L-shaped, T-shaped, Y-shaped and/or anchor-shaped.

A hook shape of the end part enables a particularly strong connection, in particular with a relatively slight depth relative to the upstanding wall. Moreover, when the first passage in the front of the receiving element is relatively narrow with respect to a width of the hook shaped end part, this can counteract the structural arm unexpectedly moving laterally out of the receiving element, for instance during receiving or setting.

Optionally, the receiving element and the end part are so dimensioned that the end part can be received in the receiving element with play in three mutually orthogonal translation directions and/or around three mutually orthogonal rotation axes.

The earlier-mentioned advantage of being able to set the position of the end part can thereby be utilized to a particularly large extent, for instance substantially for all degrees of freedom, at least for any non-trivial range within each respective degree of freedom.

Optionally, the setting space or the play between the end part and the receiving element is at least 1 cm, for instance circa 2 cm, or more than 2 cm, for instance circa 3 cm, circa 4 cm, circa 5 cm, or more. More preferably, the end part is receivable in the receiving element, with a setting space provided between the receiving element and the end part. The setting space is the space that is around the end part between the end part and the walls of the receiving element. That space can be used to set the end part in the proper position relative to the receiving element, and also, this space can be optionally filled with insulating material and/or curable connecting material.

Such play can offer a proper balance between on the one hand less strict requirements regarding the positioning of the receiving element in the building and on the other hand a relatively compact construction. The play is, for instance in one direction but more preferably in two or three mutually orthogonal directions, at least such a distance.

Optionally, the structural arm forms a balcony element or the structural arm forms part of a balcony element. Thus, a building construction with the above-mentioned advantages can be extended to include a balcony element, for instance in the context of alterations or renovations. Instead of or in addition to the balcony element, a different type of overhanging facade element can possibly be provided. What holds more generally is that where in this disclosure mention is made of a balcony element, a balcony construction, etc., a different type of overhang can possibly be provided.

Optionally, the structural arm forms a bridge element or the structural arm is part of a bridge element. Thus, a building construction with above-mentioned advantages can be extended to include a bridge element, whereby for instance a bridge element can be realized which, for instance, connects two buildings and/or building parts, in particular at a height.

A balcony element or bridge element can for instance comprise one or more steel beams, which can each be regarded as a structural arm. A balcony element or bridge element is for instance prefabricated. A balcony element or bridge element comprises for instance a concrete or other floor part in which or to which the one or more steel beams have been cast in or otherwise connected.

According to a further aspect, a building construction is provided. The building construction comprises a building system as described herein, with the end part received in the receiving element. Preferably, the end part is fixed in the receiving element.

Such a building construction, as already explained above, can be realized relatively easily and/or fast, in particular with good insulating properties.

Optionally, the building construction using the building system comprises a balcony construction.

Alternatively or additionally, the building construction using the building system comprises a floor construction, a roof construction, a bridge construction, or another construction, in particular a construction that is safely loadable by persons and/or goods, including for instance planting, such as plants, shrubs and/or trees. According to a further aspect, a building method is provided. The building method comprises providing a building system as described herein. The building method further comprises: structurally connecting at least the rear of the box-shaped receiving element of the connection set with an upstanding wall of a building; receiving an end part of the structural arm with play in the receiving element, the arm thereby extending through the first passage; setting a position of the received end part relative to the receiving element, in particular using the setting means; and structurally fixing the end part in the receiving element.

Such a building method can be carried out particularly easily and/or fast, as has already been explained hereinbefore in the context of previous aspects and options.

Setting the position of the received end part preferably comprises comparing a current position and/or orientation of the received end part with a desired position and/or orientation of the received end part. For determining and/or comparing the current position, various measuring instruments can be used, including for instance a level.

With the fixing mentioned, the set position of the end part can be made substantially permanent, at least, such that the structural arm can be safely loaded for a prolonged time. With the fixing, the set position can thus be durably defined, whereby any play still present after setting can be substantially undone.

Alternatively or additionally, in or at the filler, a resihent component may be provided in order to, after curing of the filler, offer a desired space to expansion and/or shrinkage, for instance of steel parts.

Alternatively or additionally, in or at the filler, a thermally and/or acoustically insulating component may be provided in order to, after curing of the filler, contribute to insulation between the receiving element and the end part fixed therein. Optionally, fixing the end part in the receiving element comprises: arranging a curable filler in contact with the receiving element and the end part received therein; and allowing the arranged filler to cure.

Thus, fixing can be realized particularly easily and effectively. The curable filler concerns for instance a mortar such as concrete mortar.

Optionally, the filler may be reinforced with fibers, for instance steel fibers and/or carbon fibers.

For the fixing and/or filling, the connection set and/or the building system thus comprises optionally a fixing agent and/or a filler, preferably a curable filler.

Optionally, one or more fiber-reinforced materials, for instance fiber-reinforced polymer and/or plastic, can be used in one or more elements and/or one or more constructions, for instance in a floor part, a structural arm, a structural support element such as an upright, or other component. Such use of fiber-reinforced material can provide a particularly favorable firmness with proportionally relatively httle weight.

A further object of the current invention is to be able to realize facade structures more easily and/or faster, for instance in the context of alterations or during construction of new buildings, in particular with good insulation properties and/or with accurate positioning, in particular for relatively heavy facade structures comprising for instance a heavy stone or concrete facade slab.

According to an aspect, to that end, a connection set for a facade structure is provided.

The connection set comprises a box-shaped receiving element which is configured for therein receiving an end part of a connecting arm of a facade assembly. The box-shaped receiving element has a rear which is configured to be structurally connected with an upstanding wall of a building. The box-shaped receiving element further has a front located opposite the rear. Provided in the front is a passage through which the connecting arm can extend when the end part thereof has been received in the receiving element.

The connection set further comprises a setting means for setting a position of the received end part relative to the receiving element.

The setting means is, at least during use, preferably provided at the receiving element, for instance in, on, and/or through the receiving element, as is further explained elsewhere in this disclosure.

The rear may be structurally connected with the upstanding wall in various ways, for instance via steel bolts, by anchoring, and/or by a curing of a constructional material. Besides the rear, optionally one or more further sides may be connected with the upstanding wall. Alternatively or additionally, one or more sides of the receiving element may be connected with another basic structure, for instance with a floor or a roof of a building. The receiving element is advantageously mounted by its rear against the upstanding wall of the building. This in contrast to many conventional connection sets where a part is usually secured in or through the wall. Here, no recesses need to be provided in the wall for the mounting of the receiving element: connecting with anchoring elements, such as bolts or anchors, can suffice. This is an important difference from the current conventional systems. Because of this, the assembly according to the invention can be relatively simply arranged on existing buildings, e.g. in renovations, or, in the case of new building construction, it can be relatively fast and simply attached to a core or inner skin of the building.

A facade assembly, for instance comprising a facade slab, may thus be advantageously connected via the box-shaped receiving element with a building or other basic construction. Due to the setting means provided, only a moderately accurate positioning of the receiving element relative to the building is required, while still a desired accurate positioning of the facade assembly, for instance the facade slab or other facade element, relative to the building can be achieved. The facade building process can thereby be made easier and/or be accelerated compared to presently known facade building methods. Due to the setting means provided, the connecting arm can be set in the proper position relative to the receiving element. Thus, the receiving element can be mounted to a wall of the building, and the precise positioning of the connecting arm of the facade assembly can be done by setting the arm relative to the receiving element. This in contrast to the known building methods, where the receiving element should be precisely positioned.

In presently known facade building methods, by contrast, such play is normally avoided, which makes setting impossible. The consequence is that strict requirements are to be met regarding the positioning of, for instance, a receiving element relative to a respective building and/or a connecting arm relative to a respective facade assembly, as a result of which the facade building process becomes relatively complex and slow. In the known facade building methods, the receiving element should be mounted quite accurately, which requires a lot of time and skills on the part of the construction worker. In the known facade building methods, the end part of the connecting arm is usually received in the receiving element with a proper fit, so that a, typically, form-closed connection comes about. While this provides for a proper transfer of force, it does not provide for any possibilities of setting, and also results in a cold bridge which leads to a decrease of the insulation value of the building as a whole.

When the end part has been received in the receiving element, the end part in the receiving element is surrounded by a setting space or clearance, being a space or clearance in which the end part can be set relative to the receiving element. The setting space is determined by the distance between the end part and the receiving element in the length direction and/or the width direction and/or the height direction of the receiving element. The setting space may correspond to play provided, but may also be greater than usual play. Due to the setting space, the end part, and hence the structural arm, can be set in the desired position relative to the receiving element. The desired position can be a desired height, desired depth or a desired orientation or angle.

When the end part has been received in the receiving element and the position thereof has been set as desired, the end part is preferably fixed in the receiving element, as is further explained elsewhere in this disclosure. With such fixation, advantageously a strong and stable facade structure can be obtained after the aforementioned setting has been finished. For that matter, such a fixation need not preclude the end part being post-set in the course of time. Quite the contrary: such post-setting preferably remains possible thus, whereas this is normally not the case in prior art constructions.

Also, it can remain possible to replace the facade assembly in the course of time, for instance when a facade slab has got damaged. A replacement facade assembly can then, after the old one has been removed, be connected and set in substantially the same way via the receiving element. The permanent setting possibility thus makes it possible that a replacement facade assembly is not an exact copy of the facade assembly to be replaced, while a desired accurate positioning can still be achieved then.

The receiving element and/or the end part may for instance be manufactured substantially of steel.

Optionally, the connection set further comprises an insulant arranged in the box-shaped receiving element, for reducing transfer of heat and or sound between the receiving element and the end part received therein. Advantageously, the insulation is arranged on several sides, for instance all around, in the box-shaped receiving element, around the end part received therein. By providing insulation on several sides, possibly all around, a situation can be obtained where there is no connection of steel with steel, not even with any minimal fastener such as a bolt. By avoiding steel-steel contact, cold bridges can be avoided and a proper thermal insulation can be obtained.

Thus, advantageously, improved insulation properties of the realized facade structure can be obtained, while the above-mentioned advantages are preserved. In particular, thus a firm construction can be obtained which is free of a steel connection between inner skin and outer skin. Such a steel connection could otherwise transmit heat and vibrations, which is undesirable. In known constructions, normally, such a steel connection is still present, for instance via one or more steel bolts, so that a cold bridge is formed and vibrations are transmitted.

Optionally, the insulant is manufactured of a rubbery material.

The rubbery material is or contains, for example, neoprene.

Neoprene has as a special advantage that it can provide not only thermal and/or acoustic insulation but also a relatively even transfer of force between the respective construction parts. Thus, also vibrations can be damped or counteracted. In this way, therefore, not only a thermal insulation, but also an acoustic insulation can be achieved.

Optionally, at least two mutually movable parts of the connection set are manufactured of steel, with the insulant being configured to counteract direct contact between the steel parts mentioned. To that end, the insulant is for instance arranged between the steel parts, possibly but not necessarily attached to one of those parts, such that the parts remain mutually movable, for instance settable. Thus, said parts can mutually transmit forces, in particular via the insulant, while mutual transfer of heat and/or sound can be counteracted. Optionally, the box-shaped receiving element has a substantially open top. Thus, an interior of the receiving element can be easily accessible from the top, for instance for arranging an internal setting means and/or an insulant and/or a filler. Also, the end part can be arranged in the box shaped receiving element along the top thereof.

Optionally, the passage and the substantially open top are both part of a same continuous opening in the box-shaped receiving element.

In this way, the end part of the connecting arm can be placed in the receiving element easily, for instance from above, so that the arm thereupon extends through the passage.

Optionally, the setting means comprises at least one setting element for use as internal spacer between a bottom and/or sidewall of the box-shaped receiving element and the received end part. Advantageously, the setting means is provided between a wall of the receiving element and the end part. The setting means can comprise at least one setting element, with the setting element preferably extending from the wall of the receiving element towards the end part. Advantageously, the setting element extends through the wall of the receiving element, so that the setting element can be operated from outside to set the end part, and the connecting arm associated therewith, in the desired position. When the end part and the connecting arm connected therewith have been set in the desired position with the aid of the at least one setting element, the at least one setting element can further function as fixation element to keep the end part and the connecting arm connected therewith in the desired position. Because of this, a separate fixation means, for instance cast concrete, can be omitted. Thus, for instance, the remaining setting space between the end part and the inner walls of the receiving element can be filled up with insulation material.

Such a setting element can provide a setting means in a compact and yet stable manner, and with little material use. Optionally, the at least one setting element comprises at least one setting plate and/or at least one setting bolt for use as spacer between the box-shaped receiving element and a nearby part of the received end part.

Such a setting plate and/or setting bolt can provide a setting element in a user-friendly and effective manner.

Optionally, the at least one setting element is configured to substantially fix a set distance between a sidewall of the receiving element and the received end part.

To that end, the at least one setting element comprises for instance at least two setting elements which exert forces in opposite directions on the end part, for instance from both sides of the receiving element. The end part may thus in a substantially fixing manner be clamped at a desired position, between setting elements and/or between a setting element and a wall of the receiving element. Such clamping, however, is not strictly necessary: a close movement limitation can suffice.

Optionally, the insulant is provided at least at the at least one setting element, to counteract transfer of heat and/or sound between receiving element and end part via the at least one setting element. To that end, the insulant is for instance provided between a setting element and the end part and/or between a setting element and the receiving element, whether or not attached to one or more of said parts.

Preferably, the end part is dimensioned so as to be received with play, or setting space, in the box-shaped receiving element of the connection set, in particular while the connecting arm extends through the passage.

Because of such play, which, as mentioned, is lacking in presently known facade building methods, a position of the received end part relative to the receiving element can be set, for instance by means of an internal spacer between receiving element and end part and/or by external actuation of the connecting arm. The setting space or play mentioned preferably concerns play all around, that is, such play that the end part, at least as to dimensions, is floatingly receivable in the receiving element.

It will be clear that the setting means can thus be provided in one or more of various possible forms. The concrete shape or shapes of the setting means, as will be clear, can be chosen depending on the specific conditions of the facade structure to be realized and/or preconditions of the facade building process.

Optionally, the passage is provided substantially centrally in the front of the box-shaped receiving element.

The receiving element is hence particularly suitable for receiving an end part which is substantially symmetrically widened with respect to a part of the connecting arm at the location of the passage. Such an end part is for instance T-shaped, Y-shaped or anchor-shaped, as is further explained elsewhere in this disclosure.

Alternatively or additionally, the passage may be provided off-centrally. Such a variant is for instance suitable for receiving of an L-shaped end part, though an L-shaped end part could also be used in combination with a central passage.

According to a further aspect, a facade building system is provided. The facade building system comprises a connection set as herein described; and the facade assembly comprising the connecting arm with the end part, the end part being dimensioned to be received with play in the box-shaped receiving element of the connection set.

With the facade building system, above-mentioned advantages can be achieved. As mentioned before, the play can in particular make the setting of the position of the end part in the receiving element easier, whereby such setting makes a less accurate positioning of the connection set relative to the building allowable, so that the facade building process can be made easier and/or accelerated. Optionally, the end part is provided with an insulant for reducing transfer of heat and/or sound between the receiving element and the end part received therein.

Such an insulant of the end part may for instance be provided as an addition or alternative to the earlier-mentioned insulant, with substantially corresponding advantages.

A hook shape of the end part enables a particularly firm connection, in particular with a relatively slight depth relative to the upstanding wall. Moreover, when the passage in the front of the receiving element is relatively narrow with respect to a width of the hook-shaped end part, this can counteract the connecting arm unexpectedly moving laterally out of the receiving element, for instance during receiving or setting.

Optionally, the receiving element and the end part are so dimensioned that the end part can be received in the receiving element with a play, preferably a setting space, in three mutually orthogonal translation directions and/or around three mutually orthogonal rotation axes.

Optionally, the setting space or clearance between the end part and the receiving element is at least 1 cm, for instance circa 2 cm, or more than 2 cm, for instance circa 3 cm, circa 4 cm, circa 5 cm, or more. More preferably, the end part is receivable in the receiving element, with a setting space provided between the receiving element and the end part. The setting space is the space that is around the end part between the end part and the walls of the receiving element. That space can be used to set the end part in the proper position relative to the receiving element, and also, this space can be optionally filled with insulation material and/or other filler material.

Optionally, the facade assembly comprises a facade slab, with the connecting arm extending from the facade slab, in particular from a rear of the facade slab.

Thus, with the above-mentioned advantages a facade structure with such a facade slab can be realized. The facade slab is for instance manufactured of a stony material, for instance natural stone and/or concrete. Alternatively or additionally, one or more other materials can be used in a facade slab, for instance metal, glass, wood, plastic, etc.

A facade assembly, for instance a facade slab, can optionally be provided with a solar panel, a wind turbine, a heat exchanger, a sun shade, a light source, a screen, a plant holder, a water drain, a sealing, and or any other device or provision known per se for use in or on facade structures. A facade assembly, for instance a facade slab, can have different shapes and dimensions, and can also be provided with one or more openings therethrough, for instance for viewing and/or ventilation.

According to a further aspect, a facade structure is provided, comprising a facade building system as herein described, wherein the end part is received in the receiving element, and is preferably substantially fixed therein.

Such a facade structure, as already explained above, can be realized relatively easily and or fast, in particular with a high positional accuracy and/or with a high insulation value. Preferably, the connecting arm then extends from the rear of the facade slab into the receiving element.

The connecting arm may thus in an elevational view of the facade structure be substantially hidden from view, in particular by the facade slab.

According to a further aspect, a method is provided for realizing a facade structure, in particular on a building, in other words, a facade building method. The method comprises: providing a facade building system as herein described; structurally connecting at least the rear of the box shaped receiving element of the connection set with an upstanding wall of a building or other basic construction; receiving the end part of the connecting arm with play in the receiving element, the arm thereby extending through the passage; and setting a position of the received end part relative to the receiving element.

Such a facade building method can be carried out particularly easily and/or fast, as has already been explained hereinbefore in the context of earlier aspects and options.

In setting, as described hereinbefore, use can be made of the setting means.

Preferably, the set position is substantially fixed, to thus realize a particularly stable facade structure.

Optionally, the method comprises arranging a thermally and/or acoustically insulating filler in the receiving element, in particular next to the received end part. Any space left in the receiving element after setting can thus be utilized for improvement of insulation. The insulating filler comprises for instance foam and/or wool.

DETAILED DESCRIPTION

Figs. 1A-4 and 7A-7D show examples of a connection set 1 for a building construction 2. The connection set 1 comprises a box-shaped receiving element 3 which is configured for therein receiving an end part 4 of a structural arm 5. The box-shaped receiving element 3 has a rear 6 which is configured to be structurally connected with an upstanding wall 7 of a building 8, as well as a front 9 located opposite the rear 6, in which a first passage 10 is provided through which the structural arm 5 can extend when the end part 4 thereof is received in the receiving element 3. The connection set further comprises a setting means 11 for setting a position of the received end part 4 relative to the receiving element 3.

Figs. 1A-4 and 7A-7D also show examples of a building system 20 comprising: the connection set 1; and a structural arm 5 having an end part 4 which is dimensioned so as to be received in the box-shaped receiving element 3 of the connection set 1 with play S.

Figs. 1A-4 and 7A-7D also show examples of a building construction 2 (at least, relevant parts thereof) comprising the building system 20, with the end part 4 received in the receiving element 3, and preferably fixed therein. Figs. 1A-4 and 7A-7D illustrate furthermore a building method, comprising: providing the building system 20; structurally connecting at least the rear 6 of the box-shaped receiving element 3 of the connection set 1 to an upstanding wall 7 of a building 8; receiving an end part 4 of a structural connecting arm 5 with play S in the receiving element 3, the arm 5 thereby extending through the first passage 10; setting a position of the received end part 4 relative to the receiving element 3, in particular using the setting means 11; and structurally fixing the end part 4 in the receiving element 3.

In the figures, the above-mentioned play, or setting clearance, is indicated with arrows S. It will be clear that the play shown may for instance be used for translation, or rotation, or a combination thereof, of the end part 4 within the receiving element 3. Thus, the position of the end part 4 within the receiving element 3 as shown in the figures must always be understood as being only one of many possible positions, especially depending on use of the setting means 11.

In embodiments, the setting means 11 comprises at least one setting plate 17 (see Figs. 1A, 1C) as a setting element 17 for use as spacer between a bottom 18 of the box-shaped receiving element 3 and a thereon supported part of the received end part 4. In the example of Figs. 3A-C the setting means 11 comprises provisions such as openings in sidewalls for setting bolts (not shown) as setting elements. It will be clear that various types of setting elements for use as internal spacer(s) can be combined. Moreover, such setting elements may be combined with one or more external setting means 26.

In embodiments, the setting means 11 comprises at least one external setting means 26 (see Figs. 2 and 4) for use as settable support construction for the structural arm 5 outside, in particular at a distance from, the receiving element 3. The external setting means 26 may for instance be directly or indirectly supported on or to the building 8, for instance on or to a wall 7 and/or a floor part 23 thereof.

While in Fig. 2 as an example schematically an external setting means 26 is shown that engages the structural arm 5 substantially at one point, one external setting means, or a plurality of external setting means, can engage the structural arm 5 at more points, for instance as shown in the example of Fig. 4. Due to engagement at more points, setting the position of the end part 4 relative to the receiving element 3 can be further facilitated, in particular setting in different directions and/or degrees of freedom.

In the example of Fig. 4, an external setting means 26 is formed by an assembly of components which are indicated in Fig. 4 with A, B, C, D and E. Component D concerns a beam or a combination of beams, for instance with a steel I -profile, which extends along the structural arm 5 and further into the building 8, in particular along a floor 23 thereof. The beam D is coupled by means of components A (for instance with threaded rods) to the structural arm 5 and by means of component B (for instance also with threaded rods) to the building floor 23. Components C keep the beam D to some extent at a distance from floor 23 and arm 5, so that a lever action is made possible which can be operated by adjustment of component B for instance with a jackscrew or hydraulic pump), so that setting of the position of the end part 4 relative to the receiving element 3 is possible. It may be, for instance, that also some or all components A and/or C are adjustable for further setting of the end part 4. Optionally, one or more (whether or not adjustable) shores E may be used, for instance, as in Fig. 4, between the beam D and a superjacent floor 23.

While in Fig. 4 substantiahy one assembly of components A-E is shown, the at least one external setting means 26 preferably comprises a plurality of such assemblies, for instance each with respective mutually connected components A-E, and/or variations thereof. In that case, several beams D may be arranged substantially parallel to each other at some distance from each other. In some cases, for instance for a balcony that continues around a corner of a building 8, beams D can be placed at an angle to each other, whereby they, for instance, cross each other (for instance at somewhat different levels) within the building 8.

In general, it holds that an external setting means 26 as shown in Fig. 4 is easily adjustable to the specific building situation, and hence is particularly universal in its application possibilities. At the same time, such an external setting means 26 takes up relatively little space and can easily be arranged and removed. The external setting means 26 may for instance be already attached to the structural arm before the end part 4 is placed in the receiving element 3, for instance in a prefabrication step of a balcony. Upon placement of the balcony, the end part 4 can be placed in the receiving element 3, after which the beam(s) D can be coupled to the floor 23 to help secure the construction and to make the setting mentioned possible.

The at least one external setting means 26 may optionally be removed in the course of time, in particular when the end part 4 is durably fixed in the receiving element 3, for instance after curing of a curable filler 16 provided in the receiving element 3.

In the examples shown, the setting means is partly formed by the structural arm 5 with its end part 4, the end part 4 being dimensioned to be received with play S in the box-shaped receiving element 3 of the connection set 1, in particular while the structural arm 5 extends through the first passage 10, allowing a position of the received end part 4 relative to the receiving element 3 to be set by external actuation of the structural arm 5. Such external actuation of the arm 5 may for instance be performed via said at least one external setting means 26.

In embodiments, the fixing of the end part 4 in the receiving element 3 comprises: arranging a curable filler 16 in contact with the receiving element 3 and the end part 4 received therein (see Figs. 1A, 1C,

7 A); and allowing the arranged filler 16 to cure. To counteract leaking away of the filler 16, and to contribute to further insulation, prior to arrangement of the filler 16, the first passage 10 is preferably sealed, in particular with a sealant 29 (see Figs. IB and 7 A) such as, for instance, a foam band.

During the filler 16 (and optionally 25) being arranged and allowed to cure, the structural arm is preferably stably supported outside the connection set 1, the end part 4 thereby being particularly stably retained in its set position. Such a support may for instance be achieved with a temporary support construction, for instance using a prop and/or a tackle. The temporary support construction can be removed after curing.

In embodiments, the connection set 1 further comprises an insulant 12 arranged in the box-shaped receiving element 3 for reducing transfer of heat and/or sound between the receiving element 3 and the end part 4 received therein.

In embodiments, the insulant 12 is manufactured of a rubbery material, in particular neoprene. Alternatively or additionally, one or more other materials may be used to promote insulation and/or force distribution between receiving element 3 and end part 4, for instance a foam material and or a fibrous material.

In the examples of Figs. 1A-C and 7A-B, the receiving element 3 on its inner side is substantially completely clad with the insulant 12. The insulant 12 in this example is moreover arranged between a filler 16 and a further filler 25, which fillers are further explained elsewhere in this disclosure.

In the example of Figs. 3A-C, the insulant 12 is substantially provided on a bottom 18 of the receiving element 3.

In embodiments, fixing the end part 4 in the receiving element 3 further comprises: covering the end part 4 and/or the filler 16 with insulant 12, and arranging on the covering insulant 12 a further filler 25 (see Figs. 1A, 1C, 7B). In embodiments, the end part 4 is provided with a respective insulant 21 for reducing transfer of heat and/or sound between the receiving element 3 and the end part 4 received therein.

In Fig. 3B, for simplicity of the drawing, such an insulant 21 is shown only along a few surface sections of the end part 4. It will be clear that such an insulant 21 can extend as an alternative or addition along further surface sections of the end part 4, and may thereby, for instance, surround the end part 4.

It will be clear that various combinations and variations of insulants are possible.

In embodiments, the box-shaped receiving element 3 has a substantially open top 13.

In embodiments, the first passage 10 and the substantially open top 13 are both part of a same continuous opening 10, 13 in the box-shaped receiving element 3.

In embodiments, the connection set 1 further comprises a blocking element 14 (see Figs. 1A, 1C and 7A-D) connectible with the receiving element 3, which is configured, when in connection with the receiving element 3, to counteract the end part 4 moving via the top 13 out of the receiving element 3. In the examples shown, the blocking element 14 and the receiving element 3 are mutually connectable by means of bolt connections 27. By thus connecting the blocking element 14, for instance by tightening the bolt connections 27, a bias can be incorporated in elastic insulant 12, for instance of neoprene, which promotes an effective transmission of high dynamic loads.

The bolt connections in Figs. 1A-C are oriented substantially vertically, that is, substantially perpendicular to the top 13. In Figs. 7A-D it can be seen that alternatively or additionally bolt connections 27 may be oriented substantially horizontally, that is, substantially parallel to the top 13. It will be clear that in each of such embodiments the receiving element 3 is preferably provided with correspondingly oriented and positioned mounting holes, for instance provided with internal thread, for bolts of the bolt connections 27.

The blocking element 14 is for instance manufactured of steel, for instance in accordance with the receiving element 3.

In embodiments, fixing the end part 4 in the receiving element 3 further comprises connecting together of the blocking element 14 and the receiving element 3, in particular with generation of bias as described hereinabove.

In embodiments, in the blocking element 14, a second passage 15 is provided for supplying a filler 16 and/or 25 therethrough into the receiving element 3.

In embodiments, the first passage 10 is provided substantially centrally in the front 9 of the box-shaped receiving element 3.

In embodiments, the end part 4 is substantially hook-shaped, for instance L-shaped, T-shaped (see Figs. IB, 3B, 7 A), Y-shaped and/or anchor shaped.

In embodiments, the receiving element 3 and the end part 4 are so dimensioned that the end part 4 can be received in the receiving element 3 with play S in three mutually orthogonal translation directions and/or around three mutually orthogonal rotation axes.

In embodiments, the play S between the end part 4 and the receiving element 3 is at least 1 cm, for example circa 2 cm or more, such as circa 3 cm, circa 4 cm, circa 5 cm or more.

In embodiments, the receiving element 3 is provided at its rear 6 with at least one anchor 19 (see Figs. 2 and 7B-D) for anchoring to the upstanding wall 7. For instance, the anchor 19 may be arranged between a ceiling plate and a floor plate, or be mounted on or under a floor plate or ceiling plate, which form the floor 23. Possibly, it may be arranged in a floor plate or ceiling plate, for instance in a recess in a floor plate or ceiling plate, or possibly the anchor 19 may be integrally cast in a floor plate or ceiling plate. In a modular construction procedure, it is advantageous to mount the anchor 19, for instance, in or to or between a part of the floor 23, preferably without the anchor needing to be co-cast and hence curing having to be waited for.

In the example of Fig. 2, the front 9' of the receiving element 3 is of slightly oblique configuration, where in particular respective wah sections extend at a slight angle to a vertical plane, where preferably a top of said wall sections is located further forwards compared with a bottom. Such a shape can facilitate receiving of the end part 4 in the receiving element 3 from above.

It will be clear that thus various form variations of the receiving element are possible.

In embodiments, it holds that the structural arm 5 forms a balcony element 22 (see Fig. 2) or is part thereof. Alternatively or additionally, it can hold that the structural arm forms a bridge element or is part thereof.

As can be seen in the example of Fig. 2, the balcony element 22, and more generally the structural arm 5, may be provided with a sword part 30 for taking up a moment of arm 5 around a tilting point that is adjacent to the receiving element 3. The sword part 30 can for instance cooperate with a spacer 31 arranged under the receiving element 3. Optionally, the spacer 31 and/or the sword part 30 is provided with a respective setting element (not shown) to set a tilt of the arm 5. The sword part 30 extends from the structural arm 5 downwards and can thus be supported against, for instance, the spacer 31. The spacer 31 is at a distance under the receiving element 3, and is connected with the receiving element 3, for instance via a rear part which extends downwards from the rear of the receiving element. By providing such a spacer 31 and/or sword part 30, also very heavy elements, which exert a relatively great moment on the wall 7, can be attached to the wall 7 in a secure and reliable manner. The space around the rear of the spacer 31 and/or between the spacer 31 and the sword part 30 is advantageously filled up with insulation material 28.

In embodiments, the building construction 2 using the building system 20 comprises a balcony construction 24 (see Fig. 2). Alternatively or additionally, the building construction using the building system can comprise a bridge construction.

A bridge construction may be realized, for instance, by repeating the connection shown in Fig. 2 (in particular with receiving element 3 and end part 4) in a mirrored fashion on an opposite side of the structural arm 5 continuing outside the drawing, that is, on the right-hand side outside the drawing, in particular mirrored relative to a plane of symmetry extending vertically on the right-hand side of the drawing, perpendicular to the plane of the paper.

It will be clear, for that matter, that various variants of bridge constructions are possible, where the structural arm to be connected extends substantially between buildings and/or building parts, in particular between upstanding walls, to connect those mutually.

A bridge construction is for instance suitable for therealong transferring people and goods, and or for strengthening of a building construction, and or for hanging therefrom or supporting thereon further elements, and/or for architectonic embelhshment.

As can be seen in Fig. 2, the connection set 1 can be used in a particularly compact manner in a building construction 2, for instance between an inner skin and an outer skin of an outer wall of a building, for instance substantially in an insulation layer between said inner skin and outer skin. Outside the receiving element 3, thus, preferably an external insulant 28 is provided, for instance an insulation wool and/or an insulation foam.

Thus, building constructions such as balcony constructions and bridge constructions can be realized more easily and or faster, in particular with good thermal and acoustic insulating properties. In further illustration of this, in Fig. 8 an example of a building 8 is shown, in which it is indicated with reference numerals 1 at what positions by way of example a connection set 1 can be used to promote the insulating properties mentioned, for instance in a new building to be built and/or in renovations of a building. At the same time, via the connection set 1 great forces can be transferred as in a dynamically loaded balcony construction, while an accurate setting and post-setting as well as relatively fast and simple assembly is enabled.

In and/or on such a building 8, for instance, one or more wind turbines may be provided, in particular at a top of the building 8, while connection sets 1 can advantageously contribute to the acoustic insulation of the wind turbines relative to one or more parts of the building 8. During use, the building 8 may thus, for instance, be energy neutral, without users of the building 8 thereby having to experience noise nuisance.

Figs. 5A-6C show examples of a connection set 1 for a facade structure 102. The connection set comprises a box-shaped receiving element 3 which is configured for therein receiving an end part 104 of a connecting arm 105 of a facade assembly 130. The box-shaped receiving element 3 has a rear 6 which is configured to be structurally connected with an upstanding wall 7 of a building 8, as well as a front 9 located opposite the rear 6, in which a passage 10 is provided through which the connecting arm 105 can extend when the end part 104 thereof is received in the receiving element 3. The connection set 1 further comprises a setting means 11 for setting a position of the received end part 104 relative to the receiving element 3.

Figs. 5A-6C also show (parts of) examples of a facade building system 120 comprising: the connection set 1; and the facade assembly 130 comprising the connecting arm 105 with the end part 104, the end part 104 being dimensioned to be received with play S in the box-shaped receiving element 3 of the connection set 1. Figs. 5A-6C also show (parts of) examples of a facade structure 102 comprising the facade building system 120, with the end part 104 received in the receiving element 3, and preferably substantially fixed therein.

In Figs. 6A-C, of the facade assembly, at least the connecting arm 105 with end part 104 is shown, while the facade assembly according to the example of Figs. 6A-C can further comprise a facade slab 131, for instance according to Figs. 5B-C.

Figs. 5A-6C moreover illustrate a method for realizing a facade structure 102, in particular on a building 8. The method comprises: providing the facade building system 120; structurally connecting at least the rear 6 of the box-shaped receiving element 3 of the connection set lwith an upstanding wall 7 of a building 8 or other basic construction; receiving the end part 104 of the connecting arm 105 with play S in the receiving element 3, the arm 105 thereby extending through the passage 10; and setting a position of the received end part 104 relative to the receiving element 3, in particular using the setting means 11. Preferably, the set position is substantially fixed.

In the figures, said play, or setting clearance, is indicated with arrows S. It will be clear that the play shown can be utihzed, for instance, for translation, or rotation, or a combination thereof, of the end part 104 within the receiving element 3. Accordingly, the position of the end part 104 within the receiving element 3 as shown in the figures must always be understood as just one of many possible positions, especially depending on use of the setting means 11.

The rear 6 may for instance be mounted to the upstanding wall 7 with bolts (not shown). To this end, holes and/or other engagement structures may be provided, for instance in the rear 6 and/or in one or more parts 33 which, relative to the receiving element, project out, in particular in the plane of the sidewall 128 located at the rear 6. Such optional projecting parts, or lips, 33 may, as can be seen in Figs. 5B and 5C, for instance project horizontally and/or vertically, for instance on one or more sides, and may for instance be formed in one piece with said wall 128 or be otherwise attached thereto.

A particularly firm connection may for instance be achieved at the location of a coupling between upstanding wall 7 and an inner floor of the building 8.

In embodiments, the facade assembly 130 comprises a facade slab 131, which is for instance manufactured of a stony material such as natural stone or concrete and may thus be relatively heavy. The connecting arm 105 may then extend from the facade slab 131, in particular from a rear 32 of the facade slab 131.

The connecting arm 105 is preferably manufactured of steel, and may be connected in various ways known per se with the facade slab 131, in particular on the rear 32 thereof, for instance by screws, by gluing, and/or by coupling to an optional reinforcement structure or other strengthening structure of the facade slab 131.

In embodiments, the connecting arm 105 extends, at least after connection, from the rear 32 of the facade slab 131 up to and into the receiving element 3, in particular through the passage 10.

In embodiments, the box-shaped receiving element 3 has a substantially open top 13 (see e.g. Figs. 5C, 6C).

In embodiments, the passage 10 and the substantially open top 13 are both part of a same continuous opening 10, 13 in the box-shaped receiving element 3.

In embodiments, the passage 10 is provided substantially centrally in the front 9 of the box-shaped receiving element 3.

In embodiments, the end part 104 is substantially hook-shaped, for instance L-shaped, T-shaped (see Figs. 5B, 6B), Y-shaped and/or anchor shaped. In embodiments, the connection set 1 further comprises an insulant 12 and/or 21 arranged in the box-shaped receiving element 3, for reducing transfer of heat and/or sound between the receiving element 3 and the end part 104 received therein. The insulant 12 and/or 21 may be arranged in various places, as can for instance be seen in the drawings, and as is further explained elsewhere in this disclosure.

In embodiments, the insulant 12 and/or 21 is manufactured of a rubbery material, in particular neoprene. As an alternative or addition, one or more other materials may be used to promote insulation and/or force distribution between receiving element 3 and end part 104, for instance a foam material and/or a fibrous material.

In embodiments, at least two mutually movable parts of the connection set 1 are manufactured of steel, while the insulant 12 and/or 21 is configured to counteract direct contact between said steel parts.

Thus, in the example of Figs. 5A-C, insulant 12 and/or 21 is arranged between the end part 104 and the bottom 18 of the receiving element 3 (see Figs. 5A and 5C), as well as between the end part 104 and setting elements 17 (see Figs. 5B and 5C).

In embodiments, the end part 104 is provided with an insulant 12 and/or 21 for reducing transfer of heat and/or sound between the receiving element 3 and the end part 104 therein received.

In Fig. 6B, for simplicity of the drawing, such an insulant 21 is shown only along a few surface sections of the end part 104. It will be clear that such an insulant 12 and/or 21 can extend alternatively or additionally along further, possibly even all, surface sections of the end part 104, see for instance Figs. 5B-C.

It will be clear that various combinations and variations of insulants are possible, with which in particular steel-on-steel contact and/or other forms of cold bridges can be counteracted. In embodiments, the setting means 11 comprises at least one setting element 17, for example a setting plate and/or a setting bolt, for use as internal spacer between a bottom 18 and/or sidewall 127-129 of the box-shaped receiving element 3 and the received end part 104.

In Figs. 5A-C various types of setting elements 17 are shown, including setting plates at the rear 6 (sidewall 128) and the bottom 18, and setting bolts at the rear 6 (sidewall 128) and the sidewalls 127 and 129. It will thus be clear that various types of setting elements, whether or not in combination, can be used. Setting elements 17, for instance setting bolts, may be provided with a respective retaining means, for instance a retaining nut.

In Figs. 6A-C, with numerals 11, various holes are indicated for setting bolts not shown there, which holes may thus be regarded as alternative or additional setting means 11.

In embodiments, the at least one setting element 17 is configured to substantially fix a set distance between a sidewall 127-129 of the receiving element 3 and the received end part 104.

Thus, in Figs. 5B-C, it can for instance be seen that the end part 104 is substantially fixed in its set position by setting elements 17 around the end part 104, whereby a fixing clamping of the end part 104 relative to the receiving element 3 can occur, in particular using a resilient (as in the case of neoprene) intermediate insulant 12 and/or 21.

Alternatively, the end part 104 is not, or hardly, clamped, but still a freedom of movement of the end part 104 associated with the play S in the receiving element 3 is substantially undone by the at least one setting element 17.

Depending on expectable force exertion on the facade structure 102, it may be acceptable not to limit such freedom of movement, or to limit it only a little, on one or more sides of the end part 104. When for instance only little or no upward force on the end part 104 is expected, it can suffice to have a vertical position of the end part 104 stabilized only by the inherent weight of the facade assembly 130, that is, without any further limitation of movement at the top 13 of the receiving element 3. When, however, for instance because of wind, such limitation at the top 13 is desired, then, to that end, for instance a blocking element in the form of a cover (not shown) may be mounted to the top 13 of the receiving element 3, after the end part 104 has been incorporated therein and been set. Between such a blocking element and the end part 104, possibly, also a setting means may be provided.

In embodiments (see e.g. Figs. 5A-C), the insulant 12 and/or 21 is at least provided at the at least one setting element 17 to counteract transfer of heat and/or sound between receiving element 3 and end part 104 via the at least one setting element 17.

In the examples shown, the end part 104 is dimensioned to be received with play S in the box-shaped receiving element 3 of the connection set 1, in particular while the connecting arm 105 extends through the passage 10. This allows a position of the received end part 104 relative to the receiving element 3 to be set, for instance by means of a settable internal spacer 17 between receiving element 3 and end part 104.

In embodiments, the receiving element 3 and the end part 104 are dimensioned such that the end part 104 can be received in the receiving element 3 with play S in three mutually orthogonal translation directions and/or around three mutually orthogonal rotation axes.

In embodiments, the play S between the end part 104 and the receiving element 3 is at least 1 cm, for instance circa 2 cm or more, such as circa 3 cm, circa 4 cm, circa 5 cm or more.

The connection set 1 may for instance be used in a particularly compact manner in a facade structure 102 of a building 8, for instance between an inner skin and an outer skin of a building, for instance substantially in an insulating layer between said inner skin and outer skin. The connection set 1 comprises the connecting arm 105 which at an end is provided with the end part 104. At the opposite end of the connecting arm 105, the connecting arm 105 is configured to receive a facade element. The facade element can be a facade panel or a facade slab, for instance a concrete facade slab. The facade elements together can form the outer skin of the outer wall of the building, or the facade elements may be outside the outer skin of the outer wall of the building.

In embodiments, the method comprises arranging a thermally and/or acoustically insulating filler 116, for instance wool and/or foam, in the receiving element 3, in particular next to the received end part 104.

Such a filler 116 might also be arranged outside the receiving element 3, for instance when the receiving element 3 is positioned in an insulating layer of a building 8. The filler 116 may then, via the open top 13 and/or via the passage 10, substantially run on between inside and outside the receiving element 3 (see e.g. Fig. 5B).

Thus, facade structures, for instance on buildings, can be realized more easily and/or faster, in particular with good insulating properties, in particular with accurate positioning.

Numerical simulations have meanwhile demonstrated that with a connection set according to the invention highly favorable thermal insulation values can be obtained in a building node of a building construction, where in an example a so-called c-value (chi-value) was realized of 0.03455 W/K. For a same construction, it was found from further numerical simulations that a very high mechanical stability can be reahzed, whereby, for instance, a balcony element of 3 m depth under high load only bends 15 mm at its distal end.

While the invention herein has been explained on the basis of examples of embodiments, these examples do not constitute any limitation of the invention, which is defined in the claims. Many variations, combinations and extensions are possible, as will be clear to the skilled person. Thus, in a single receiving element and/or connection set, for instance, at the same time two or more end parts may be included, for instance two L-shaped or T-shaped end parts, for instance via a same first passage or each via a respective first passage. A single facade assembly and/or a single facade slab may be associated with, for instance be provided with, a plurahty of connecting arms. A single facade assembly and/or a single connecting arm may be associated with, for instance be provided with, a plurality of facade slabs. Further examples of possibilities are indicated at various points in the description. For the purpose of clarity and a concise description, features are herein described as part of the same or separate embodiments, however, it will be clear that the scope of the invention can encompass embodiments with combinations of all or some of the features described. It will be understood that the embodiments shown have the same or like components, apart from where they are described as being different. The mere fact that certain features are mentioned in mutually different claims does not mean that a combination of these features cannot be used to advantage. Many variants will be clear to the skilled person. All variants are understood to be encompassed within the scope of the invention which is defined in the following claims.
