EP3216968B1 - Middle support for a building opening with large clearance - Google Patents

Description

The invention relates to a central support for a building opening with a clear width with at least two roller doors or rolling grilles provided thereon, and a central support device which contains this central support.

Building openings with a large clear width and possibly a large clear height, such as those found in aircraft hangars, market halls or garages for fire engines, can be provided with a single gate covering the entire building opening. This means that the entire building opening can be closed and opened quickly in a single step. Using a single large roller shutter or grille can be disadvantageous. It can happen that only a small area of the building opening should be opened, which is not possible when using a single large gate. In addition, with large roller shutters, an enormously high wind load affects the entire surface of the roller shutter, which can lead to severe damage, particularly in the event of a storm.

To solve these problems, it was proposed to use two or three gates with a smaller width instead of a single rolling gate or windable gate that spanned the entire building opening, between which a movable center support is arranged lockable, which with the help of guide rails mounted on the side of the center support unrolled or unrolled gates leads and supports laterally. To close a completely open building opening, the horizontally movable central support is first moved along a running track mounted in the lintel above the building opening into its central position between adjacent wound-up roller doors and locked in this central position. The roller shutters can then be unwound to close the building opening. Your side edges are guided and supported when unwinding in vertical guide rails of the center support. Because of their locking in the lintel and in the ground the center support can absorb and divert a wind load. As a result, the entire gate device is better protected against damage, in particular in the event of a storm.

Hörmann KG sells a center support (trade name SSG "Sliding Side Guide") for a double roller door in a building opening with a large internal width. The center support comprises a base support with a clamping unit mounted on it and side guide rails. The center pillar is covered by a cover plate or a profile covering in order to obtain a visually appealing finish to the center pillar on the outside of the building. The center support can be moved horizontally along a running rail and can be locked in its central position between the two roller shutters and in a parking position with the help of the locking unit.

DE 20 2015 000 015 U1 discloses a gate device with at least two gates and a central support which can be locked in a central position and which has at least one profile element serving as a side support for both gates, on which gate guides are provided. The center support is mounted on a guide rail and can be moved in the horizontal direction. For locking it, the center support has a push rod mechanism with at least one push rod and a locking mechanism. The push rod comprises two spaced engagement elements, which are designed to engage with a floor-fixed and / or building-fixed counter-element for locking.

In their load-bearing components, the center supports described above essentially consist of differently shaped, cut steel sheets and steel profiles. The use of steel for the load-bearing components is necessary in order to ensure the mechanical strength, in particular in the case of large building openings and a correspondingly long central support, in particular against a wind load. Center supports made of sheet steel can, however, have a considerable weight if dimensioned accordingly, such as for an aircraft hangar. The high weight makes it difficult to assemble the center support. On the other hand, due to the high weight, the running rail mounted on the lintel must be designed and fixed particularly stable. Bringing the many together Components also require a large number of work steps. In the DE 20 2015 000 015 U1 disclosed center support also has no outer cladding; the visual impression is often in need of improvement. With the SSG center support from Hörmann KG, an advantageous visual impression is achieved either with a cladding panel or with a patterned profile, such as an aluminum U-profile, on the side of the center support that corresponds to the outside of the building.

DE 10 2013 109 326 A1 discloses a support for a profile system, which has a rod-shaped base body made of a fiber-reinforced plastic material and a functional strip made of a metal, which can be connected to other parts of the profile system. The rod-shaped base body can be a hollow profile, on the inside of which a function strip is arranged, on which a toothed belt drive is arranged in the base body.

US 4,449,562 discloses a center post that is removably fitted between two adjacent roller doors and can be fixed by a lock. The center post comprises an extruded aluminum profile with a U-shaped central section, in which two flange means facing one another form a slot-like recess together with the base of the U-shaped section. The tongue of a locking device for locking the middle post can be inserted into the slot-like recess open on the front. A retaining element of the locking device is attached to a vertical side wall of the extruded profile. The upper end face and the lower end face of the extruded profile are open.

US 3,191,549 discloses a movable mullion made of an extruded aluminum profile, which is arranged between roller shutters closing a railway wagon. The upper end of the middle post can be fixed in the operating position with the aid of a closing plate which is fastened to the vertical inside of the middle post. The lower end of the mullion can be fixed by means of locking bolts, which are arranged on the inside of the front surface of the extruded profile and can be operated with a handle, which is attached to the outside of the front surface and through slots in the front surface is connected to the locking bolts. The extruded profile has a closing plate at its lower end, which prevents the rolling door from coming out.

According to a further aspect, the invention provides a gate device with at least two rolling gates and / or rolling grilles, which comprises at least one center support according to one of the previously explained configurations or a center support device according to one of the previously explained configurations.

The center support created in this way has several advantages.

The base body of the center support, which is an extruded profile, is advantageously extruded from aluminum. After the correspondingly shaped die has been produced, extrusion is a simple, quick and inexpensive process.

In extrusion, a monolithic base body is obtained, unlike in the prior art, in which essentially welded bodies are used. The remaining components of the center support can be easily mounted on the large surfaces of the monolithic base.

With a base body made of extruded aluminum, good corrosion protection is immediately obtained, since aluminum has a self-passivating effect due to the spontaneous surface oxide formation. The extruded base body can accordingly be further processed as it is after the extrusion as a semi-finished product. In contrast to steel profile elements, galvanizing is not necessary.

The extruded profile preferably has screw grooves that are already pressed on. With appropriately designed dies, the screwing grooves are created in the same work step as the base body from the extruded profile itself. The pressing screwing grooves already present in this way enable simple screwing.

In extrusion, light metals, such as aluminum in particular, are used to manufacture at least the base body. With the base body, the central component of the center support is made of aluminum, which enables significant weight savings compared to a steel base support. This applies in particular to a central support several meters long, which is required for dividing the opening of an aircraft hangar. The lower weight of the base body helps with the assembly of the center support. There are more options and freedoms when dimensioning the running rail system, which has to bear a lower load. Lighter aluminum center supports also result in lower transport costs due to the weight saving. Extruded profiles made of aluminum or the like are easier to process by drilling, sawing and screwing than components based on steel.

Center supports have a front visible surface, which together with the surface of the gates should make a visually appealing impression when the gates are closed. The visible area of the center supports is improved on the front by surface profiling. The surface profiling can already be created during the extrusion of the base body by means of a suitably designed die. Further post-processing for the purpose of optical design is then possible, but not necessary.

It may happen that modifications have to be made when assembling the center support and the center support device on the construction site, for example by creating holes in the base body of the center support. These modifications can be made easily and without loss of corrosion protection, because unlike a steel component, the aluminum surface does not have to be galvanized.

A particularly great advantage of the center support created here is that the center support is particularly light and stiff at the same time. The low weight is necessary because, for example, a center support with a length of more than 4 m would be difficult to handle. The combination of lightness and rigidity is achieved by using aluminum in an extrusion process, by creating stiffening connecting webs between main surfaces of the extruded profile during extrusion, which divide the extruded profile into at least two chambers, and by creating fastening profile areas on an inner surface of the extruded profile and in the corners, which in addition to their groove function also have a stiffening function.

In Fig. 1 a perspective view of a central support 10 for a building opening with a large clear width is shown with two roller doors provided thereon. The center support 10 serves to support and guide two adjacent ones laterally Rolling gates (not shown) if they are unwound from the winding shaft to close the building opening.

The center support 10 comprises a base body 11 in the form of an extruded profile 12, in particular made of light metal, such as aluminum.

On the extruded profile 12 there is a locking device 14 for locking the center support 10 in a central position between the two roller doors, a left guide rail 16 and a right guide rail 18 for guiding and supporting a side edge of the unrolling roller doors and rollers 20 for a horizontal displacement of the center support 10 attached to a track.

The extruded profile 12 in the form of an elongated cuboid has a front surface 22 (in Fig. 1 not visible), a rear surface 24 and a left side surface 26 and a right side surface 28 (in Fig. 1 not visible). The end faces 29 (see Fig. 2 ) of the extruded profile 12 are open before fastening the components of the center support 10.

The center support 10 is in Fig. 1 shown clearly shortened. The extruded profile 12 actually used has - depending on the height of the building opening - a height of up to approximately 900 cm,
All components of the center support 10 are mounted on the rear surface 24 and on the upper end face of the extruded profile 12 and thus show after the installation of the center support 2 at the building opening into the interior of the building. The side surfaces 26, 28 have smooth metal surfaces. A decorative surface profile 56 is formed on the front surface 22 (see Fig. 2 ), which is formed simultaneously with the extruded profile 12 during extrusion.

The locking device 14 comprises two parallel lower locking bars 30, which are guided vertically by means of a lower locking bar guide 32, and two parallel upper locking bars 34, which are guided vertically by means of an upper locking bar guide 36. Both locking bar guides 32, 36 have a cover plate 64 which is fastened with cover plate screws 38 to the open end faces 29 of the extruded profile 12 in fastening profile regions 58 produced during extrusion. The locking rods 30, 34 are actuated by a locking mechanism, here z. B. in the form of a rotary bolt 40, which is connected via a lower push rod 42, an upper push rod 44, a lower locking rod holder 46 and an upper locking rod holder 48 with the lower and upper locking rods 30, 34. When the rotary drive bolt 40 is actuated, the upper locking rods 34 are moved upwards and the lower locking rods 30 are moved downwards until they engage in depressions, not shown here, in the lintel, such as in a lintel plate, and in the floor by locking the central support 10. The push rods 42, 44 are fastened with push rod holders 54 on the rear surface 24 of the base body 12.

The left guide rail 16 comprises an extruded C-profile with its gap opening 78 pointing to the left in the direction of the side edge of the first roller door to be unwound. Correspondingly, the right-hand guide rail 18 comprises mirror-symmetrically from an extruded C profile with the gap opening 78 to the right in the Side edge of the second roller shutter. Both guide rails 16, 18 are provided at their upper end with funnel elements 50 which facilitate the insertion of the side edges of the roller doors when the doors are being unwound. The guide rails 16, 18 are fastened with screws in bores in the rear surface 24 of the base body 11. In contrast to the fastening profile areas 58 in the end faces of the extruded profile 12, these bores are only produced after the extruded profile 12 has been extruded.

On the cover plate 64 of the upper locking rod guide 36, rollers 20 are fastened, which are inserted into a downwardly open C-profile-shaped running rail during wall mounting

Fig. 2 shows a perspective view of the extruded profile 12 forming the base body of the central support 10 in the form of a hollow chamber profile, which has a shortened longitudinal axis L for a clearer illustration. The ratio of width B to depth T of the extruded profile 12 is 2 to 10, here approximately 4.4.

The actual length of the extruded profile 12 in a center support 10 corresponds, for example, approximately 10 times the length L. The front surface 22 has the decorative surface profile 56. The surface profiling 56 of the front surface 22 and the fastening of all components on the rear surface 24 of the base body 12 make it possible to use the central support 12 in an opening in the building after all the components have been installed without additional decorative cover.

On its inside 57, the extruded profile 12 has fastening profile regions 58 projecting inward into the cavity.

To further stiffen the extruded profile 12, it is divided into at least two hollow chambers 60 by at least one central connecting web 62.

The surface profiling 56, the fastening profile areas 58 and the connecting web 62 are produced together with the extruded profile 12 by extrusion in a single process step.

Fig. 3 shows an enlarged detail of the in Fig. 2 Extruded profile 12 shown, in which the surface profile 56 and the fastening profile areas 58 in the corners and on the inner surfaces of the extruded profile 12 can be seen more clearly. The fastening profile regions 58 and the connecting web 62 are formed in one piece with the extruded profile 12 during extrusion and are therefore integrally fixed to the extruded profile 12. They thus bring about a stiffening of the extruded profile 12. A groove 59 extending along the longitudinal axis L of the extruded profile 12 is provided in the fastening profile region 58. The grooves 59 in the corners and the surfaces of the base body 12 serve as screwing grooves for screwing on the cover plate 64 of a locking rod guide 32, 36.

In Fig. 4 the extruded profile 12 is shown in a cross-sectional view. The extruded profile 12 has, in its corners and on its front surface 22 and its rear surface 24, fastening profile regions 58 in which there are perpendicular the grooves 59 extend to the cross-sectional area. The fastening profile areas 58 are constructed mirror-symmetrically with respect to their local surroundings. The connecting web 62 runs horizontally between the front surface 22 and the rear surface 24 and divides the extruded profile 12 into two hollow chambers 60 of the same size.

The transitions between the connecting web 62 and the inside 57 of the extruded profile 12, like the transitions between the fastening profile regions 58 and the inside 57 of the extruded profile 12, are rounded, which likewise contributes to the stiffening of the extruded profile 12.

Fig. 5 shows in a further enlargement level a section of the cross-sectional representation of the extruded profile 12 comprising a part of the front surface 22 with a surface profile 56 and a fastening profile region 58 arranged symmetrically in the corner between the front surface 22 and the side surface 28 with existing therein in the direction of the longitudinal axis of the extruded profile 12 extending groove 59, which serves for screwing the cover plate 64 of a locking rod guide 32, 36.

Such a locking rod guide 32, 36 is shown in perspective in Fig. 6 shown. The locking rod guide 32, 36 has a rectangular cover plate 64 with the dimensions of the open end face 29 of the extruded profile 12 and at a right angle from it a narrower rectangular base plate 65. The cover plate 64 is firmly screwed to the extruded profile 12 on the end face. For this purpose, twelve cover plate bores 68 are formed in the cover plate, the exact arrangement of which corresponds to the arrangement of the twelve fastening profile regions 58 in the end face of the extruded profile 12. The base plate 65 is screwed tightly to the rear surface 24 of the extruded profile 12. For this purpose, five base plate bores 69 are formed in the base plate 65, which correspond to corresponding drill holes in the rear surface 24 of the extruded profile 12. Cover plate 64 and base plate 65 are thus tight and flat on the extruded profile 12. Furthermore, the base plate 65 has, at opposite ends, two guide elements 66, which protrude at right angles and are formed therein circular openings 67. The openings 67 are each arranged in pairs so that they are suitable for receiving and guiding a locking rod 30, 34. Two guide elements 66 arranged in parallel lie in one plane with the cover plate 64 and, in relation to the base plate 65, extend in the opposite direction to the cover plate 64.

For the guidance and support of the side edge of the roller door that unwinds from the winding shaft, the in Fig. 1 and more detailed in Fig. 7 shown left guide rail 16 is provided, which is mounted on the rear surface 24 of the extruded profile 12. The guide rail 16 is aligned with its longitudinal axis parallel to the longitudinal axis of the extruded profile 12. The basic component of the guide rail 16 is an extruded C-profile 74, in particular made of light metal, more particularly made of aluminum, with two leg surfaces 80 and a base surface 82. The leg surfaces 80 open at their longitudinal edge in hollow chamber regions 84 produced during extrusion (see Fig. 8 ), which make the extruded profile the extruded C-profile. The gap opening 78 is formed between the hollow chamber regions 84, in which the lateral edge of the unrolling roller door is guided. The hollow chamber regions 84 are designed in such a way that the funnel elements 50, which together form the funnel for easier insertion of the roller shutter edge, can be fastened on their upper side.

Fig. 7 shows in the partial figures 7a, 7b and 7c the guide rail in three different side views. The left in Fig. 7a The side view of the guide rail 16 shown shows the outside of the base surface 82 of the extruded C-profile, which in the assembled state of the guide rail 16 projects at a right angle from the rear surface 24 of the extruded profile 12. When the guide rail 16 rotates through 180 ° about its longitudinal axis in the paper plane, this results in the right in Fig. 7c Shown side view, which reveals the view of the hollow chamber regions 84 formed on the longitudinal edges of the leg surfaces 80. The elongated hollow chamber areas 84 form the vertical opening gap 78 between the inner longitudinal edges for guiding the roller door in the C-profile. The right view further shows the vertical opening gap 78 and behind it a narrow visible area of the inside of the base surface 82 of the extruded C-profile. The middle side view of the Fig. 7b shows the leg surface 80 of the Extruded C-profile, which is visible in the assembled state of the guide rail 16 when the rear surface 24 of the extruded profile 12 is viewed. Bores 76 are formed in the leg surface 80. The opposite leg surface 80, which is not visible here, is in flat contact with the rear surface 24 of the extruded profile 12. It also has leg surface bores 76 which serve to firmly connect the guide rail 16 to the rear surface 24 of the extruded profile 12.

The right guide rail 18 is mirror-symmetrical to the left guide rail 16 and is otherwise identical to it, so that the description of the left guide rail 16 above can be referred to for its description.

The cross-sectional view of the guide rail 16 in Fig. 8 shows the already related to Fig. 7 described leg surfaces 80 and base surface 82 of the extruded C-profile 74 and the hollow chamber regions 84 adjoining the leg surfaces 80, between which the gap opening 78 is formed for receiving the gate. Additionally shows Fig. 8 that the extruded C-profile 74, like the extruded profile 12, has fastening profile regions 58 with grooves 59 formed therein. Brush seals 86 and sliding profiles 88 are fastened on the inner surfaces of the hollow chamber regions 84, which together form the gap opening 78.

According to a preferred embodiment, the center support 10 is together with the in Fig. 9 lintel plate 90 shown in perspective. The lintel plate 90 has lintel plate holes 92 for fastening the lintel plate 90 to the lintel above the building opening. On the left and right edge of the lintel plate 90, lintel extrusion hollow profiles 94 with a C-profile structure are fastened, which likewise have fastening profile regions 58 and to which double funnel elements 96 are fastened, which form paired double funnels for receiving the side edge of the roller door to be unwound. In the lower, horizontally projecting area of the lintel plate 90, lintel plate openings 98 are formed, into which the ends of the locking rods 34 engage when the Center support 10 is locked by actuating the rotary lock 40 and lifting the locking rods 34.

An overall perspective view of a center support device 100 is shown in FIG Fig. 10 pictured. The center support device 100 comprises a center support 10 as shown in FIG Fig. 1 is shown, the lintel plate 90 and in addition a running rail 102 with wall brackets 104 and a stopper 106. The running rail 102 here has a C-profile with a downward opening into which the rollers 20 of the central support 10 are movably inserted.

The center support device 100 can be attached to a door lintel with the running rail 102 and the lintel plate 90. The lintel plate 90 has lintel plate openings 98 for receiving the locking rods 34 in order to achieve the locking of the central support 10. Fig. 10 also shows floor sleeves 108 which are inserted into the floor with a precise fit below the two lintel plate openings 98 of the lintel plate 90. When the central support 10 is locked by actuating the rotary drive bolt, the lower locking rods 30 are moved downwards until they engage the base sleeves 108 while the central support 10 is locked.
