Definitions

  • the present invention relates to a roller shutter box made of brick material with a substantially U-shaped cross section.
  • roller shutter boxes are known per se from the prior art, see e.g. DE-A-41 42 049 and EP-B-239.053.
  • shaped stones coated with binder are placed on the end face and e.g. with several reinforcements running in the longitudinal direction and a binding agent to form a rigid roller shutter box.
  • roller shutter boxes produced in this way are relatively complex and expensive.
  • the known roller shutter boxes made of brick material often have poor thermal insulation properties.
  • the gluing area In order to make the end-face gluing sufficiently durable, the gluing area must be correspondingly large, which in turn requires correspondingly large wall thicknesses and at most enables small void cross-sections in the bricks.
  • roller shutter boxes made of brick material basically have the positive property that they largely correspond in terms of their surface and also in terms of their thermal expansion coefficient to the brick material from which the house walls usually consist, i.e. they form homogeneous plaster supports with the house walls, which affects durability and Adhesion of a plaster layer and in terms of avoiding plaster cracks has a positive effect.
  • the present invention has for its object to provide a roller shutter box and a method for its manufacture, which on the one hand maintains the positive properties of roller shutter boxes made of brick material, but on the other hand is cheaper to manufacture and should preferably also have an improved thermal conductivity.
  • roller shutter box itself, this object is achieved in that it is made from a continuous one-piece brick material or brick block, the length of which is at least 90 cm.
  • Preferred embodiments of the invention are characterized in that the length of the one-piece brick material blocks is at least 1.20 m, preferably at least 1.60 m, whereby one-piece brick blocks of over 2.50 m in length (specifically 2.60 m) can also be realized in practice are.
  • Such roller shutter boxes can therefore be delivered from the start in the correct desired length in one piece and do not require any further processing before use at a construction site. In particular, they do not have to be assembled from individual pieces and glued, and they also do not have to be cast with reinforcing elements.
  • the object on which the invention is based is therefore achieved in that the mouldable brick clay material is extruded to a minimum length of 90 cm by means of a corresponding matrix or press mold. Behind the extrusion nozzle or matrix, the initially still box made of brick material is expediently picked up by a conveying device and transported as stress-free as possible according to the extrusion speed.
  • an embodiment of the invention is preferred for which the walls forming the U-profile, that is to say the two walls each forming a U-leg and the crossbar connecting them, have hollow chambers.
  • Such hollow chambers improve the thermal insulation properties of the roller shutter box. Since, because of the one-piece design of the roller shutter box according to the invention, end-face gluing of shaped blocks is no longer required, the cross-sectional areas required for gluing also no longer have to be present, so that the hollow chamber cross sections, based on the total cross section of the roller shutter box, account for a considerably larger proportion of the total cross section of the Can have roller shutter box.
  • Embodiments of the invention are therefore preferred in which at least one of the two legs of the U-profile, namely the leg facing the inside of a building during installation, but preferably also the outside leg and the transverse web, have an average void proportion which is at least 50 % of the total cross-sectional area of the leg or crossbar. In particularly preferred variants, this cross-sectional area proportion of the cavities is in the order of approximately 60% and above. It is already preferred due to the method of manufacture if the roller shutter boxes are manufactured as hollow chamber profiles with a constant profile cross section. The cross-sectional relationships and thus also the thermal conductivity properties are then the same everywhere perpendicular to the longitudinal direction of the roller shutter box.
  • the favorable cross-sectional ratio of the cavity cross-section to the cross-section of the brick material itself is achieved by the walls of the hollow chambers facing outwards, but in particular also the intermediate walls of the hollow chambers having a correspondingly small wall thickness.
  • Embodiments of the invention are therefore preferred, in which in particular the horizontally running walls of the hollow chambers, i.e. the partition walls in the vertically running U-legs and the walls of the hollow chambers of the crossbar adjoining the outside of the U-profile and on the inside of the U-profile have a maximum wall thickness of 12 mm, better of less than 10 mm and particularly preferably less than 8 mm.
  • wall thicknesses down to 5 mm have already been tried out.
  • the wall thicknesses of the vertical walls of the hollow chambers should not exceed 12 mm, preferably 10 mm.
  • the hollow chambers should have the same cross-section as far as possible, but at least have a cross-sectional area that is essentially the same in amount.
  • the cavities of the legs and the transverse web of the U-profile are filled with thermal insulation material, preferably foamed with PU foam, to improve the thermal insulation.
  • thermal insulation material preferably foamed with PU foam
  • the constant profile cross-section and the cross-sectional areas of the cavities with the same amount prove to be extremely favorable, because then the PU foam consists of a number of tubes or nozzles which can be inserted into the cavities and have a constant filling rate can be filled, with the pipes or nozzles being retracted in all cavities at the same speed, while at the same time the same amount of PU foam or other thermal insulation material emerges from all pipes. Since the cavities have approximately the same cross-sectional areas in terms of their amount and therefore also an identical volume overall, all cavities are filled evenly in such a procedure.
  • the total wall thickness of the legs of the U-profile should be at most 50 mm, but preferably less than 40 mm, e.g. 38 mm, the internal dimension of the hollow chambers of the legs in the thickness direction of the legs should be at least 24 mm, preferably at least 26 to 28 mm.
  • the external dimensions of the roller shutter box correspond to the usual requirements and standards for all common types of masonry and are e.g. 300 x 300 mm2 in cross-section or more, for example 300 x 365 mm2, with a clear internal dimension between the legs of at least 200 to 225 mm and a slightly larger clear height from the inner base of the U-profile to that defined by the leg ends Level.
  • the free end surfaces of the two U-legs, which face away from the crossbar of the U-profile, preferably have a groove for inserting reinforcing material, if possible in connection with an aluminum rail, which serves as a plaster or plaster edge or corner rail.
  • the reinforcement may be necessary, for example, if the roller shutter box has to absorb larger loads before a lintel is completed or if two roller shutter boxes according to the invention have to be connected to one another in the case of excess lengths, for example 3 m or more.
  • the roller shutter box is overall of completely sufficient stability and can easily replace the conventional roller shutter boxes composed of brick bricks, also from a static point of view.
  • the roller shutter box itself is not a load-bearing structural element of a building, but carries loads at most until a lintel to be poured over the roller shutter box has been completed or a corresponding support has been installed.
  • the new roller shutter box is lighter and, above all, less expensive due to the reduced use of personnel during manufacture. On the top, i.e.
  • the roller shutter box preferably has at least one essentially groove-like concrete filling pocket. This is used to firmly connect the roller shutter box with the concrete of a window or door lintel to be poured directly over it, or also a concrete ceiling, by pouring the concrete onto the top of the roller shutter box during the manufacture of the lintel or ceiling and allowing it to flow into the concrete filling bag.
  • Two concrete filling pockets of this type are preferably provided, at least one of the walls of the groove-like concrete filling pockets forming an undercut by being oblique with respect to the outer surface of the crossbar and with respect to a perpendicular thereto.
  • the walls of two different concrete filling pockets should be inclined in opposite directions, so that overall, after the hardening of the concrete material intervening in both concrete filling pockets, the wedging effect of a dovetail connection results.
  • An advantage of these concrete filling pockets is also the avoidance of an air gap that can otherwise arise, for example after the lintel has hardened, due to loads or changes in load, due to thermal stresses, the building being set, etc. between the lintel and the roller shutter box. Even if the roller shutter box is not firmly anchored to the lintel, the part protruding from the lintel into the concrete filling pocket forms at least a kind of labyrinth and prevents a draft gap.
  • the U-profile is supplemented by a cover plate which closes the U-opening to form a closed box profile.
  • This end cover can be broken out and is only connected via predetermined breaking points to the free ends of the U-legs, preferably on their inner wall.
  • the brick clay material is extruded through a mold or matrix, the exit cross section of the extrusion nozzle or matrix corresponding to the cross section of the brick blank.
  • this matrix cannot be a flat molded part for the formation of cavities, but rather, for example, mandrels or reaching up to the matrix opening The like, which define the resulting voids and around which the soft brick clay material is extruded.
  • the brick clay material can still swell somewhat even after it has emerged from the extrusion nozzle or matrix, so that the wall thicknesses that ultimately result are generally somewhat larger than the extrusion gaps left free by the matrix.
  • the cross-sectional areas of the cavities are at least 22 x 60 mm2. Regardless of the cross-sectional shape, which if possible is simply rectangular, the amount of the cross-sectional area should be at least 1000 mm2. Accordingly, the number of cavities to be provided in one of the legs for a given cross-sectional dimensions of the leg of a maximum of 50 x 350 mm is, for example, six, but preferably less than five.
  • the crosspiece preferably also has only five or fewer hollow chambers, which results from the requirement for the same cross-sectional areas, based on the hollow chambers of the legs. Due to the inner surface of the crossbar, which is usually curved in a curved manner corresponding to half a circular or U-arch, at least in the corner region, i.e. at the transition between the crosspiece and the legs, a cross-sectional shape of the hollow chambers deviating from the rectangular shape if one does not want to provide excessively large wall thicknesses in these areas.
  • the concrete filling pockets which spring back behind the plane of the outer surface of the crossbar, may also force a cross-sectional shape of the cavities in the region of the crossbar that deviates from a preferred rectangular shape.
  • the blank After extrusion, the blank is fired in a conventional manner to become a hard and tough, one-piece shutter box made of brick material.
  • roller shutter box Another useful addition to the roller shutter box according to the invention is a lintel shuttering that can be placed on the roller shutter box, also made of brick material.
  • This is produced in a completely analogous manner to the roller shutter box and in turn consists of several connected, thin-walled cavities or a cavity profile with a total length of at least 90 cm.
  • this lintel formwork has an approximately L-shaped cross-section, the inner boundary of the L-profile at the transition between the two L-legs being preferably rounded in an arc.
  • this lintel formwork in the preferred embodiment has a web that can be roughly inserted into one of the concrete filling pockets. In this way, the lintel formwork be glued or cast together with the roller shutter box.
  • the webs should, if possible, be connected to the relevant L-leg of the lintel shuttering profile via predetermined breaking points so that they can be knocked off if necessary if they are to be placed on a roller shutter box without such a pocket or groove, especially when it is concerned is a conventional roller shutter box that has only the general, U-shaped cross-sectional shape in common with the roller shutter box according to the present invention.
  • the lintel formwork profile like the roller shutter box profile, is an extruded hollow chamber profile with the same preferred variants with regard to the wall thicknesses of the hollow chambers.
  • This type of lintel formwork is a so-called "lost formwork", which means that after pouring with concrete and appropriate reinforcements, this formwork made of brick material remains installed and part of the lintel.
  • the use of brick clay material in turn means that the plaster base is homogeneous with the rest of the masonry and because of the hollow chambers, it has improved heat insulation, since the concrete lintel, which is filled with a lot of reinforcing steel, itself generally does not have good heat insulation properties.
  • the lintel formwork according to the invention can be arranged on one side only on the inside or outside or on both sides, that is, in the extension of both legs of the roller shutter box.
  • the vertically extending leg of the approximately L-shaped lintel formwork profile can also be extended by attaching or plugging in extension strips.
  • extension strips also consist of brick clay material and are preferably simple rectangular pipes or the like which have standard dimensions in order to be able to gradually adapt to a desired standard height of a lintel formwork, possibly also in connection with a ceiling formwork.
  • These extensions are plugged onto the free edge of the vertical L-leg of the lintel formwork profile using cross-section double-T-shaped plastic connectors. By plugging in further plastic connectors with a double-T-shaped cross-section, additional extension strips can be placed on an already existing extension strip.
  • the legs 4 and the crosspiece have five hollow chambers.
  • the rectangular hollow chambers in the corner region would be assigned to the crossbar, this could also have six or seven hollow chambers, but such a maximum number should not be exceeded if possible in order to reduce the ratio of the hollow cross section to the total cross section and in particular the total cross sectional area of the to keep horizontal walls 5, 5 'in a favorable range.
  • Figure 1b shows a detail of the free ends of the legs 1, 2, which, as shown, have a reinforcing groove 7, in which reinforcing bars made of steel can be inserted and cast if necessary.
  • the reinforcing groove 7 is delimited by walls 8, 9, which can either be of the same thickness or, as shown, can have a different thickness.
  • the depth D1 of the reinforcement groove 7 is also approximately 15 mm in the preferred embodiment of the invention, while the wall thickness E2 of the wall 5 between the groove 7 and the hollow chamber 4 above it, similar to the other partition walls 5 between the hollow chambers, should have a thickness of approximately 5 mm .
  • the legs 1, 2 and the crossbar 3 each have only three hollow chambers.
  • two concrete filling pockets 12 with inclined side walls 13, 14 and 13 ', 14' are provided in the top of the crossbar 3.
  • the legs 1, 2 do not differ from the variant shown in FIG. 1.
  • the cross-sectional shapes of the chambers 4 "differ significantly from the cross-sectional shapes of the hollow chambers 4 or 4 ', adapting on the one hand to the curved shape of the inner surface of the U-profile and on the other hand to the concrete filling pockets 12 formed by a recessed outer wall.
  • the middle hollow chamber 4" has a cross-section deviating from the rectangular shape while adapting to the U-bend, but could also easily have a rectangular cross-section.
  • the concrete filling pockets 12 have walls 13, 13 'which run obliquely and form an undercut.
  • the walls 14, 14 'of the two concrete filling pockets 12 run parallel to this, but could also be flatter, steeper or perpendicular to the plane of the outer surface, or else inclined in the opposite direction and also form an undercut.
  • the concrete mass is also allowed on the horizontal outer surface of the Roller shutter box flow, the concrete mass penetrating into the already mentioned concrete filling pockets 12.
  • the roller shutter box After curing, the one-piece concrete block with its runners projecting into the concrete filling pockets 12 also engages in the undercuts which are formed by the correspondingly inclined walls 13, 13 ', so that the roller shutter box is firmly attached to the cast over it and with the appropriate reinforcements optionally anchoring a lintel or the like forming concrete block.
  • the roller shutter box is sufficiently stable, even with the maximum dimension of 2.60 m in length and the small wall thicknesses of 5 to 6 mm, to bear the load of a concrete lintel cast on it until it has hardened and even the load-bearing one Function. If necessary, however, the roller shutter box can additionally be supported from below or stiffened further by reinforcements cast into the groove 7.
  • an end plate 10 can be seen at the bottom in FIG. 2, which closes the free U cross section of the roller shutter box and which is connected via predetermined breaking points 11 to the free ends of the legs 1, 2 on their inner surfaces.
  • the predetermined breaking points 11 have deliberately been displaced somewhat inward away from the free inner edge of the legs 1, 2, since by breaking out the end plate 10 in the area of the predetermined breaking points, burrs may remain or a little more material may break away, but if possible the end faces or Edges of the legs 1, 2 should not be affected by this. In particular, these edges are usually covered by a rail to be fastened to them, a broken ridge possibly being disruptive.
  • the end faces of the roller shutter boxes according to the invention are preferably covered by a flush, U-shaped disc.
  • This disc or this head piece preferably also has mounting and bearing elements for a roller shutter shaft and / or for a roller shutter belt, a motor or the like.
  • the flush insert is generally made of chipboard material, but can also be made of brick material.
  • a brick cover can also be placed on the end of the roller shutter box.
  • Such a front disk or head piece is preferably glued into the U-bend of the roller shutter box, and glued on the end face when a panel is attached.
  • the roller shutter box according to the invention requires little manual work for its manufacture and completion and is therefore inexpensive. Despite the one-piece production correspondingly long brick blanks, the wall thicknesses can be kept relatively small, so that the roller shutter box according to the invention has very good thermal insulation properties. This applies in particular if the relatively large cavities provided according to the invention are also filled or foamed with a thermal insulation material, so that convection within these cavities is also prevented.
  • roller shutter box 1 can again be seen, with lintel formwork 20 placed on the inside and outside in the form of an L-shaped profile, consisting of a vertical leg 22 and a horizontal leg 23.
  • the legs 22, 23 are placed at right angles to one another and form a corresponding rectangular edge on the outside, while the inner transition between the legs 22, 23 is rounded in an arc shape, the arc-shaped curve extending to the end of the horizontal leg 23.
  • the radius of this arc corresponds approximately to the radius of the arc on the inside of the roller shutter box, even if the radii of curvature that match are not important here.
  • This shape reinforces the insulating air layer in the lower area of the lintel, where it contains a high proportion of reinforcing steel, which is relatively good heat conductor.
  • the lintel formwork 20 is shown again in cross section. It can be seen that the lintel formwork 20 also consists of a hollow chamber profile with hollow chambers 24 and 24 ', the shape, size and overall cross-sectional area of which corresponds approximately to the hollow chambers 4, 4' and 4 '' of the roller shutter box profile according to FIGS. 1 and 2. It should be noted above all that, in the preferred variant, the lintel formwork profile has a web 21 which is attached at the bottom on the outside of the leg 23 and which corresponds in cross section to the concrete filling pocket 12 and can be inserted into it.
  • the lintel formwork 20 is positioned and fixed in a very simple manner on the top of the roller shutter box.
  • two lintel formwork profiles 20 can be placed on the inner wall side and outer wall side of the roller shutter box and then close with their outer surfaces of the L-leg 22 flush with the outer surfaces of the legs 2 of the roller shutter box.
  • the web 21 is inserted into the concrete filling bag 12 and can fill it more or less. If necessary, an adhesive can also be introduced into the concrete filling pocket 12 so that the lintel formwork 20 already forms a solid unit with the roller shutter box 1 before pouring with concrete. However, if the concrete is low-viscosity or contains bindable, low-viscosity components, it can also flow between the two lintel formwork profiles 20 on the top of the roller shutter box 1 into the concrete filling pockets 12 and thus establish the firm connection between the lintel formwork and the roller shutter box.
  • the web 21 is preferably connected to the underside of the horizontal L-leg 23 via a predetermined breaking point 27 and can be knocked off if necessary, namely if the roller shutter box on which this formwork is placed does not have the concrete filling pockets 12.
