Description

SYSTEM AND |\/IETHOD FOR SUSPENDING A BALCONY ON ANEXTERIOR WALL OF A BUILDING AND USE OF SUCH SUSPENSIONSYSTEM TECHNICAL FIELDThe present disclosure belongs to a system and a method forsuspending a balcony on an exterior wall of a building.

BACKG ROUND l\/lounting a balcony on an exterior wall of a building is a non-trivial andprecise task. The balcony may either be integrally formed with the building orbe provided as pre-formed balcony modules that are mounted to the exteriorwall structure of the building. The latter may be made by providing the exteriorwall structure of the building with a plurality of beams that project out from thewall structure and further providing a framework module which comprises aplurality of apertures to be aligned with the longitudinal extension of therespective beam. The framework module is mounted to the beams byinserting the beams into their respective apertures in the framework module.Hence, in other words, the framework module is slid onto the beams. Thus, inthe resulting installation, the weight of the balcony will be supported by thebeams.

Since a balcony is arranged in an elevated position in view of theground it is essential that the work of suspending the framework module assuch may be made as easy as possible. Any angular misalignment of thebeams, even a small one as measured close to the wall structure, will cause asubstantial horizontal and/or vertical misalignment as seen at the free ends ofthe beams. Such a misalignment may cause a so-called drawer effect whichmakes it considerably more difficult to insert the beams into correspondingopenings in a framework module. The suspension work is made by one ormore cranes, which requires a highly skilled personnel due to the overallsmall tolerances, heights and weights. lnstallation of a balcony also involves a 2 substantial cost in terms of machinery since at least one crane must beallocated. Thus, it is essential that the installation time may be reduced.

Further, it is essential that the following levelling of the suspendedframework module may be made in an easy manner to ensure that theflooring of the installed balcony will be horizontal. Further, since the overallvisual appearance of the building and the balconies is of essence, there is astrive towards balconies where beams, fastening elements, etc. areconcealed to as large extent as possible.

Hence, there is a need for a framework of a balcony that allows a simplified mounting.

SUMMARY The main object of the invention is to provide a system allowing aneasy suspension of a modular balcony.

Another object is to provide a system that allows an easy suspensionand levelling of a modular balcony.

Yet another object is that the suspension system should be applicableno matter if it is a mounting that is made during a new construction of abuilding or as a retrofit.

These and other objects are met by a suspension system for a balconycomprising: a first support configured to be mounted on an exterior wall of abuilding, said first support, in a free end thereof facing away from the building,comprising an end plate supporting a projection, and a second support configured to suspend a framework of a balcony, said second support, in a free end thereof configured to face towards the exterior wall, comprising a locking plate, said locking platecomprising an opening configured to receive the projection of the endplate of the first support, thereby suspending the framework of thebalcony.

The first support is to be mounted on the exterior wall of the building.The exterior wall of the building may occasionally henceforth be referred to as 3 the wall. The first support may be directly or indirectly casted into the wall.The locking plate of the second support is securely fastened to the end plateof the first support without using tools orjoining means, hence facilitatingmounting and reducing mounting time, etc. Upon a plurality of first andsecond support plates have been mounted, the balcony is slidingly fitted ontothe plurality of first supports, further facilitating mounting and reducingmounting time without compromising on security. Thus, by the presentinvention, a simplified and faster suspension process is provided for and alsoan overall safer working environment is provided for since the amount ofmanual hands-on work may be reduced. This applies no matter if thesuspension is made during the erection of a new building or as a retro-fittingto an existing building.

The locking plate may further comprise a first adjusting bolt and asecond adjusting bolt, said bolts being arranged on opposite sides of alongitudinal center line of the locking plate, wherein said bolts are threadinglyreceived by threading in through-going bores in the locking plate, and whereina free end of respective bolt is configured to abut the end plate of the firstsupport in a condition when the framework of the balcony is suspended by thesecond support.

The term longitudinal center line is to be understood being asubstantially vertically aligned geometrical line intersecting in a vicinity of acenter of mass of the locking plate while the locking plate is in its use position.A similar terminology will be used for the end plate below.

The adjusting bolts allow levelling of the second support relative to thefirst support thereby facilitating slidingly mounting the framework of thebalcony onto a plurality of second supports. The adjusting bolts may furtherfacilitate levelling of the framework such that a possible inclination of abalcony floor can be adjusted after mounting of the balcony on the exteriorwall. As the two adjusting bolts can be independently adjusted, the adjustingbolts may allow adjusting a direction of the first support in the horizontaland/or the vertical plane prior to slidingly mounting the balcony onto thesupport. The adjustment is made to ensure that a top surface of the 4 framework of the balcony will be levelled, i.e., have a horizontal extensionwhen in use. Further, since the framework of the balcony is configured to besuspended by a plurality of second supports, it is essential that all beams areproperly arranged in a parallel relationship. This adjustment may as well bemade by the two adjusting bolts of each second support. The adjusting boltsmay thereby allow adjustment of the second support to be substantiallyperpendicular to the wall of the building. The adjusting bolts may therebyfunction as a ball joint between the first and the second support.

The opening in the locking plate may have a keyhole-shapedconfiguration comprising an insertion portion merging with a locking portion,wherein the insertion portion has a first width, and the locking portion has asecond width, the first width exceeding the second width.

The keyhole-shaped configuration may allow a secure and self-tightening mechanism. This feature may further enhance convenience duringmounting. Time and manpower may thereby be reduced.

The opening in the locking plate may be configured to receive theprojection of the end plate by a bayonet coupling having an insertion portionand a locking portion.

This may facilitate mounting and reduce time and manpower.

The opening in the locking plate may have a wedge shape configuredto receive the projection of the end plate, said opening having an insertionportion and a locking portion.

The wedge shape may provide similar advantages as the key-holeshaped configuration above. The locking plate may have a non-uniformthickness such that the thickness in a vicinity of the locking portion is largerthan the thickness in vicinity of the insertion portion. Thereby the first supportmay be further secured to the second support.

The first support may be a beam.

The length of the beam may be in the range of 0.1 -O.5 m. The divisionof the suspension system into the first and the second support facilitate scaffolding since the first support typically can be substantially shorter than the second support, which second support can be mounted in connection tothe installation of the framework of the balcony.

The first support may have a longitudinal extension forming an angle toa major surface of the exterior wall of the building.

This may reduce a vertical mounting space of the first support on thewall, hence providing a vertical alignment of the balcony floor with respect toa floor level of a room in connection with the balcony.

The opening may be a through-going hole, or a recess.

A through-going hole may simplify manufacturing of the locking plate. Athrough-going hole may further allow a reduced thickness of the locking plate.

The projection, in a free end thereof, may comprise a head portion,said head portion having a width being smaller than the first width of theinsertion portion and exceeding the second width of the locking portion.

The projection may be arranged along a Iongitudinal center line of theend plate of the first support.

According to a second aspect, there is provided a method comprisingmounting a plurality of first supports on an exterior wall of a building, eachsupport, in a free end thereof facing away from the building, comprising anend plate supporting a projection, providing a plurality second supports, eachsecond support in a free end thereof configured to face towards the exteriorwall, comprising a locking plate comprising an opening configured to receivethe projection of the end plate of the first support, said opening having aninsertion portion and a locking portion, and mounting a second support toeach support of the first type by moving the second support linearly along afirst direction allowing the projection of the end plate of the first support to bereceived in the insertion portion, and moving the second support linearlyalong a second direction different from the first direction, thereby allowing theprojection to be lockingly received in the locking portion, thereby suspendingthe second support by the first support.

The method may further comprise levelling each support of the secondtype by using at least one adjusting bolt supported by the support of the 6 second type, said at least one adjusting bolt having a free end abutting theend plate of the respective support of the first type.

According to a third aspect, the invention refers to the use of asuspension system according to any one of claims 1-10 for mounting abalcony on a building.

Generally, all terms used in the claims are to be interpreted accordingto their ordinary meaning in the technical field, unless explicitly definedotherwise herein. All references to "a/an/the [element, device, component,means, step, etc.]" are to be interpreted openly as referring to at least oneinstance of the element, device, component, means, step, etc., unlessexplicitly stated otherwise. The steps of any method disclosed herein do nothave to be performed in the exact order disclosed, unless explicitly stated.

DETAILED DESCRIPTION The present invention will now be described more fully hereinafter withreference to the accompanying drawings, in which currently preferredembodiments of the invention are shown. This invention may, however, beembodied in many different forms and should not be construed as limited tothe embodiments set forth herein; rather, these embodiments are provided forthoroughness and completeness, and to fully convey the scope of theinvention to the skilled person. ln connection with Fig. 1, there is shown one example of balcony 1000suspended by a suspension system 300 mounted on a highly schematicallywall section 20 of a building. The wall section 20 may by way of example be acasted concrete element. lt is to be understood that the suspension system300 may be arranged to other structural elements of a building with remainedfunction.

Turning to Fig. 2, a schematic cross section of a framework 500 of abalcony as being suspended to the wall structure 20 of the building isdisclosed. The cross section is taken along the longitudinal extension of onesuspension system 300.

The suspension system 300 comprises a plurality of first supports 100and a corresponding plurality of second supports 200 for suspending thebalcony 1000. Below, the term "suspension system" occasionally refers to asystem comprising a single first support 100 and a single second support 200to facilitate readability, unambiguously appreciated by the skilled person.Each first support 100 has a longitudinal extension and each first support 100 8 is configured to be directly or indirectly mounted to the wall structure 20 of thebuilding.

The framework 500 of the balcony 1000 comprises a plurality ofguiding rails 501. The framework 500 is configured to be mounted to theplurality of second supports 200 by Iongitudinally moving the framework 500such that a respective second support 200 of the plurality of second supports200 is received in respective opening 525 of the plurality of guiding rails 501.Hence, in other words, the framework is configured to be s|id onto the pluralityof second supports. The framework 500 of the balcony is configured to belevelled in view of the plurality of first supports 100 by a plurality of adjustingbolts 216;217, further discussed in connection with Fig. 3B below.

As is best seen in Figs. 1 and 2, a top wall 503 of the framework 500 isconfigured to be covered by a plurality of ti|es 1010 forming a flooring of thebalcony 1000. The ti|es 1010 are preferably laid when the framework 500 hasbeen suspended and properly levelled. Other types of floorings are equallyapplicable within the scope of the claims. A peripheral outer edge 504 of theframework 500 is covered by protective covering plates 505. Further, theperipheral outer edge 504 of the framework 500 of the balcony is surroundedby a protective side wall forming a balcony railing 1020. ln connection with Figs 3A and 3B there is shown a suspension system300 for a balcony 1000 and an exploded view thereof. The followingdescription aims to describe a single suspension system 300 although it isunderstood that at least two suspension systems 300 are needed for properlysuspending a balcony 1000. As can be seen in Fig. 1, five such suspensionsystems 300 are shown in the present non-limiting example. The skilledperson understands that the number of suspension systems 300 depends on,e.g., the dimensions and the weight of a balcony to be mounted or the like.The suspension system 300 is arranged to suspend a balcony 1000 mountedon an exterior wall 20 of a building. The suspension system 300 comprises afirst support 100 configured to be directly or indirectly mounted on the exteriorwall 20 of a building 30, and a second support 200. The first 100 and second200 supports are preferably made as hollow extruded steel profiles. The cross 9 sections are herein disclosed as having a quadrangular cross-sectionalprofile. However, it is readily appreciated that other cross sections withremained function may be used. The cross section of at least the secondsupport 102 should be complementary to the respective guiding rai| 501 in theframework 200 of the balcony, further discussed below. Five such firstsupports 100 can be seen in Fig. 1.

The first support 100, in a free end 110 thereof, facing away from theexterior wall 20 of the building, comprises an end plate 112 supporting aprojection 114. The end plate 112 may be securely fastened to the free end110 by bolts, welding, or the like. The suspension system 300 furthercomprises a second support 200. The second support 200 is configured toallow a framework 500 of a balcony 1000 to be slidingly mounted thereto. Afree end 210 of the second support 200 is configured to face towards theexterior wall 20. The second support 200 has an elongated geometry,extending in a substantially horizontal direction, when in a use position asshown in, e.g., Fig. 1 or 3A. The second support 200 may be seen as a beam200. The second support 200 may be a hollow extruded profile having aquadrangular cross section profile when seen in a geometrical planetransverse to the extension of the second support 200. The skilled personappreciates that other variants of the second support 200 may be possiblewithin the scope of the claims.

The free end 210 of the second support 200 comprises a locking plate212. The locking plate 212 may be securely fastened to the free end 210 bybolts, welding, or the like. Alternatively, the locking plate 212 may form anintegral part of the free end 210. The locking plate 212 comprises an opening214. The opening 214 is configured to receive the projection 114 of the endplate 112 of the first support 100. Hence, the projection 114 of respectivesuspension system 300 withstand a vertical and horizontal load of thesuspended balcony 1000. The projection 114, in a free end thereof,comprises a head portion 114a. The head portion 114a has a width beingsmaller than a first width W1 of the insertion portion 214a and exceeding asecond width W2 of a locking portion 214b of the locking plate 212. The insertion portion 214a and the locking portion 214b will be further describedbelow. The projection 114 may be a bolt 114. The head portion 114a of thebolt is thereby a bolt head 114a. At least a portion of a remaining portion 114bof the bolt 114 may be threadingly received in the end plate 112 of the firstsupport 100 and tightened by a tightening nut (not shown) on a front side 120and/or a back side (not shown) of the end plate 112. Alternatively, oradditionally, the bolt 114 may be welded firmly or attached by other fasteningmeans onto the first support 100 to ensure a secure fastening of the secondsupport 200 onto the first support 100. The projection 114 is arranged along alongitudinal center line L3 of the end plate 112 of the first support 100. Theterm longitudinal center line L3 is to be understood being a substantiallyvertically aligned geometrical line intersecting in a vicinity of a center of massof the end plate 112 while the end plate 112 is in its use position. Hence, it isreadily appreciated that the longitudinal center line can have other extensionswhile the end plate 112 is not in its use position, e.g., prior to mounting of thesuspension system 300 or the like. lt is to be understood that the projection 114 may have othergeometries with remained function. By way of example, an adequatelyshaped hook may serve the purpose of the projection 114. An alternativeexample of such a hook is provided in connection with Fig. 4.

The locking plate 212 may further comprise a first adjusting bolt 216and a second adjusting bolt 217. The first adjusting bolt 216 and the secondadjusting bolt 217 are arranged on opposite sides of the longitudinal centerline L3 of the end plate 112. The longitudinal center line L3 is, when thebalcony is in a mounted position and/or in a use position, directed in asubstantially vertical direction. The adjusting bolts 216;217 are independentlyadjustable in relative to each other. The second support 200 may thereby beadjusted to be horizontally aligned prior to, or after slidingly mounting theframework 500 of the balcony 1000 onto the second supports 200. Further,the first and second supports 100;200 may be aligned to extend in a commonvertical plane. Thereby, the second supports 200 may be arranged to extendin a common horizontal plane and also to extend parallel to each other prior 11 to slidingly mounting the framework 500 of the balcony 1000 onto the secondsupports 200.

The first adjusting bolt 216 and the second adjusting bolt 217 arethreadingly received by threading in through-going bores 218;219 in thelocking plate 212. Alternatively, the through-going bores 218;219 are non-threaded. ln such a situation the bolts 216;217 may be threadingly received inbushings fixedly attached on a front side 116 and/or a back side 118 of thelocking plate 212. The bolts 216;217 may be secured in the locking plate 212by tension nuts 211;213. The tension nuts 211 ;213 are preferably located ona front side 220 of the locking plate 212, the front side 220 facing away fromthe wall 20 of the building. A free end 216a;217a of a respective bolt 216;217is configured to abut the end plate 112 of the first support 100 in a conditionwhen the balcony 1000 is suspended by the suspension system 300, therebyallowing levelling of the framework of the balcony and thereby levelling of theflooring thereof. The adjusting bolts 216;217 may allow levelling in a certaingeometrical plane and levelling relative to such a certain geometrical plane.The certain geometrical plane may be a plane of the flooring, thereby being asubstantially horizontal plane when the balcony is properly mounted, i.e.,being in its use position. A levelling relative to the certain geometrical planeallows adjustment of the second support 200 such that a plurality of secondsupports 200 may coincide with corresponding openings 525 in theframework 500 of the balcony 1000, thereby facilitating the previouslydescribed slidingly mounting of the balcony 1000 onto the plurality of secondsupports 200.

The opening 214 in the locking plate 212 may be a through-going hole214, as can be seen in Fig. SB. Alternatively, the opening 214 may be recessin the locking plate 212 with remained function. The opening 214 in thelocking plate 212 may be a keyhole-shaped configuration 214. The keyhole-shaped configuration 214 comprises an insertion portion 214a merging with alocking portion 214b. The insertion portion 214a has a first width W1. Thelocking portion 214b has a second width W2. The first width W1 exceeds thesecond width W2. Alternatively, the opening in the locking plate may have a 12 wedge shape (not shown) configured to receive the projection of the endplate, wherein the opening has an insertion portion and a Iocking portion.Such a wedge shape may be an isosceles triangle, wherein, when in the useposition, a bottom portion associated with a base of the triangle constitutesthe insertion portion and the top portion constitutes the Iocking portion.Alternatively, the opening 214 in the Iocking plate 212 may be configured toreceive the projection 114 of the end plate 112 by a bayonet coupling (notshown) having an insertion portion and a Iocking portion.

Yet another alternative Iocking mechanism is highly schematicallydescribed in connection with Fig. 4. Herein, the first 100 and the second 200support may be mutually fastened by a T-shaped projection having asubstantially constant width Wp1. A Iocking portion 1142 of the T-shapedprojection has a height Hp2 exceeding a height Hp1 of a remaining portion1144 of the T-shaped projection. A complementary Iocking plate 212 has anopening 214 having a substantially constant height Ho2 and a substantiallyconstant width Wo1. The height Hp2 of the Iocking portion 1142 may exceedthe height Ho2 of the opening 214. The opening 212 may receive the Iockingportion 1142 by rotating the Iocking plate 212 relative to the Iocking portion1142 and, subsequently, moving the Iocking plate 212 downwards such thatan upper leg 1142a of the Iocking portion 1142 is substantially received by theopening 212; see Figs 4(i) and 4(ii). When the Iocking plate 212 is moved tosuch an extent that an upper edge 2142 is in contact, or close to being incontact, with an upper surface of the remaining portion 1144 of the T-shapedprojection 114, Fig. 4(ii), the Iocking plate 212 may be rotated back, Fig. 4(iii),to regain a proper alignment between the first support 100 and the secondsupport 200. Hence, it has been exemplified that the Iocking portion of theprojection may have a height or a width exceeding a maximal height or widthof the opening 214 of the Iocking plate 212. The skilled person realizes thatthis example may be embodied in numerous ways, e.g., an L-shapedprojection, etc.

Turning to Figs 5A and 5B there is disclosed a side view of the balcony1000 when in mounted position, emphasizing the suspension system 300 in 13 the same view. ln Fig. 5A certain parts of the balcony 1000 are visuallyremoved to emphasize the extension of the second support 200 inside thestructure of the balcony 1000. As briefly described previously, the balcony1000 is slidingly mounted on the suspension system 300 onto the framework500 comprising a p|ura|ity of beams 520 aligned transversely relative to theelongated extension of the second support 200 of the suspension system300. The beams 520 thereby have through-going openings 525 having ageometry substantially complementary to a cross-sectional profile of arespective second support 200.ln connection with Fig. 5B, there is shown a schematical close-up side view of a portion of the suspension system 300 in a region close to theexterior wall 20. The suspension system 300 is thereby mounted on theexterior wall 20 in Fig. 5B. The first support 100 may be seen as a beam 100.The beam 100 may be a hollow extruded profile having a quadrangular crosssection profile seen in a geometrical plane transverse to the extension of thebeam 100. The beam 100 may be manufactured from any durable material.The beam 100 may be manufactured by steel, aluminium, or any adequatedurable alloy. This applies also for other parts described above. That is, if notexplicitly stated otherwise, the involved parts of the suspensions system aremade of a durable material, such as steel, aluminium, or any adequatedurable alloy. The first support 100 may be a beam 100 having a lengthbetween 0.1 and 0.5 meters. The first support may have a longitudinalextension L1 forming an angle A1 to a major surface of the exterior wall 20 ofthe building 20. This is best viewed in Fig. 3B. The angle A1 may deviate froma surface normal N1 of the exterior wall 20. Preferably, the angle A1 may besuch that the free end 110 of the first support 100 is located on a lowervertical level than a support end 140 of the first support 100. The angle A1may any angle between -40 and +40 degrees. The angle A1 may hence,alternatively, be such that the free end 110 of the first support 100 is locatedon a higher vertical level than the support end 140 of the first support whenmounted to the exterior wall 20. 14 ln connection with Fig. 6 there is shown a method 400 for suspendinga balcony 1000 on an exterior wall 20 of a building. The method 400comprises mounting 410 a plurality of first supports 100 on an exterior wall 20of a building, each support 100, in a free end 110 thereof facing away fromthe building, comprising an end plate 112 supporting a projection 114. Themethod 400 further comprises providing 420 a plurality of second supports200, each second support 200 in a free end 210 thereof configured to facetowards the exterior wall 20, comprising a locking plate 212 comprising anopening 214 configured to receive the projection 114 of the end plate 112 ofthe first support 100. The opening 214 has an insertion portion 214a and alocking portion 214b. The method 400 further comprises mounting 430 asecond support 200 to each first support 100 by moving the second support200 linearly along a first direction D1 (see Fig. 3A) allowing the projection 114of the end plate 112 of the first support 100 to be received in the insertionportion 214a, and moving the second support 200 linearly along a seconddirection D2 (see Fig. 3A) different from the first direction D1, thereby allowingthe projection 114 to be lockingly received in the locking portion 214b, therebysuspending the second support 200 by the first support 100.

The method 400 may further comprise levelling 440 each secondsupport 200 by using at least one adjusting bolt 216;217 supported by thesecond support 200. The at least one adjusting bolt 216;217 has a free endabutting the end plate 112 of the respective first support 100.

The above-mentioned features of the suspension system 300, whenapplicable, apply to the method 400 as well. ln order to avoid unduerepetition, reference is therefore made to the above.

The second support 200 has been illustrated being a hollow extrudedprofile beam having a quadrangular cross section transverse to an extensionof the beam. The skilled person realizes that other designs are possible withinthe scope of the claims. For instance, such a beam may be a U-shapedprofile, a circular profile, or being two joined U-shaped profiles, etc.

Accordingly and in summary, in the embodiment discussed above, the suspension system 300 is divided into two sections - the first support 100 and the second support 200. The first support 100 is configured to be fixedlymounted to the building and the second support 200 is configured to beadjustably mounted to the first support 100. The second support 200,projecting away from the building, will thereby constitute the suspensionsystem 300 which is configured to be inserted into a respective guiding rai|501 of the framework 500 of the balcony 1000. By dividing the suspensionsystem 300 in two sections, the mounting of the suspension system 300 tothe building will be substantially facilitated. Since the suspension system 300is typically mounted to the building by means of casting concrete it is easier tohandle a smaller sub-element, both in terms of volume and weight. Thisfacilitates a proper alignment of the first support 100 in view of the buildingwall 20 before mounting the second support 200 to the first support 100.Further, any angular errors between the extension of the first support 100 inview of the building may be compensated for by adjusting the second support200 in view of the first support 100 by using the adjusting bolts 216;217. Thismay be made for each suspension system 300 before mounting theframework 500 of the balcony to the plurality of suspension systems 300.Further, the longitudinal extensions of the second supports 200 of the pluralityof suspension systems 300 may be adjusted so that all suspension systems300 extend in parallel to each other prior to mounting of the framework 500 ofthe balcony 1000 to the suspension systems 300. This "bi-directional"adjustment of the suspension system 300 allows a reduction or even anelimination of any possibly occurring drawer effect during sliding mounting ofthe framework 500 to the suspension systems 300.

The person skilled in the art realizes that the present invention by nomeans is limited to the preferred embodiments described above. On thecontrary, many modifications and variations are possible within the scope ofthe appended claims.
