Abstract

The scaffolding structure, for construction applications, has support structures (5,6) of assembled welded lattices, with the poles forming at least three scaffolding pole modules (31-34), with their connection plates (35-38) acting as struts outside the structures (105-108). The scaffolding pole modules are secured to adjacent structure plates, and in succession are positioned by the central shrouding poles of head and foot spindles, together with setting nuts, to give the height levelling. The structures consist of frames (100-103) whose frame members (105-108) connect the frame corners with the pole modules.

Description

The invention relates to a construction according to the preamble of claim 1.

The supporting structure of the building construction according to the invention serves in particular to support solid structures, until it has sufficient strength achieved. This particularly includes formwork, in which, for example, concrete bridges or Prestressed concrete can be shaped. In addition, the invention to accommodate the manufacturing, maintenance, Modification or removal of structures occurring loads of components, devices and Means of transport, but also for temporary storage of building materials, components and devices. The construction according to the invention can be Assemble from individual parts at the point of use and take it apart.

The rising building supports exist according to the invention Made of steel or aluminum and are multi-stemmed Supports built from prefabricated truss.

It is known the stems of such frame supports welded together from scaffold tubes, which at are available to users of scaffolding, whereby the infills consist of plates. On the smooth scaffolding tubes of such frame supports Pipe clamps attached, with which further, from Pipe existing scaffolding elements with a positive fit the frame supports are connected. These scaffolding elements mostly serve to brace neighboring Frame supports in the form of horizontal or diagonal tubes, creating a shear-resistant structure can be manufactured.

With the previously known building constructions arise however, when assembling and dismantling the individual parts and thus considerable difficulties at the construction site. On the one hand, these are based on the fact that for the construction supports used pipes and couplings of the conventional pipe scaffolds are inherently rigid, however little to the mutual connection of multi-digit supports are suitable. The result forced use of tubular steel clamps encountered to considerable difficulties in practice because those from the frame supports and the ones described other scaffolding elements existing structures Precise alignment of the scaffolding elements which both the vertical distances and the concern angular adjustment. The conditions construction sites are unsuitable, the right one Allow alignment of the scaffolding elements, thereby the stability of the structures are endangered can.

The invention proceeds differently. Your basic idea is reproduced in claim 1. Other features of the Invention are the subject of the dependent claims.

The fact that welded according to the invention ready for installation Trusses used in the building supports find the difficult composition on the construction site the construction supports from the scaffolding tubes with the consequence that defined orientations of the Stems in the construction supports already at the construction site available. These stems are from rising Modular scaffold tubes formed, their connecting plates for bracing and thus for the production of the Structure from the building supports and scaffolding elements serves. Modular scaffolds differ from the Tube frame stands or tube coupling stands due to the structure of the supporting structure made of single stems, which are formed by pipes, which in have predetermined distances connecting plates and thereby enabling spatial structures. These connection plates are in the building supports of the invention Building construction between the infills arranged and can therefore all for the structure to be used. This gives you an exact Adjustment of the height distances. According to the invention are also the modular scaffold tubes in the direction of Bracing next to and behind each other on truss panels attached. As a result, stand in each other vertical directions always several modular scaffold tubes for attaching struts. Each according to the number of modular scaffold tubes in an inventive Building props can therefore move in any direction struts at a given height and in given distance from each other.

Finally, the building supports according to the invention to support formwork and / or components also adjustable. Spindles are used for this purpose Truss panels attached to the building supports and centrically in cladding tubes at the head and foot of the Construction supports are housed. The one on the head and Adjusting nuts on foot spindles can then used for height adjustment of the construction supports.

The invention has the advantage that it has multiple handles and height-adjustable building supports allowed as a result the training of their stems as modular scaffold tubes the exact observance of distances and arrangements of the struts, which together with the building supports an exactly adjusted spatial structure result in a simple way assembled in place and in due course can also be dismantled.

Preferably and according to the embodiment according to claim 2 will be the single pedestals of the building supports forming modular scaffold tubes to an overall rigid Composed by forming in the corners of frames are welded to the infills form the truss. In particular are this infill framework when realizing the Features of claim 3 designed so that the Module supports in the corners of the at least approximately square frame squares are welded, in the spatial structure of the building construction in Direction of the horizontal struts around a quarter circle are arranged offset, whereby the described multiple provision of Modular scaffold tubes can be achieved in any direction is.

However, it is recommended to use the fourth frame additionally stiffen. The claim provides for this 4 a suitable embodiment, it being in the As a rule, a diagonal in the frame is sufficient to weld. This also means simplification, because the diagonal frame element between opposite frame corners formed throughout can be.

Preferably and according to the features of the claims 5 and 6 you set the height adjustment of the Construction supports so that the entire travel range equally distributed on the head and foot spindles. Under practical circumstances, this can mean that the spindles have an adjustment path of the nuts of about 25 cm, so that there is a total travel of 50 cm. This travel distance corresponds then the height distance of the connecting plates and in this way allows compliance with a Grid, for the struts on the connection plates. This results in the manufacture of the building supports the further advantage that the cladding tubes, the Truss panels and the support of the head and Foot spindles are designed identically to one another can.

A particular problem can be attached to the Foot plates arise in building structures that are substantial Transfer loads, but their foundations create confined installation conditions. Stand for the erection of the rising building supports crane helpers regularly on construction sites available, but the cranes should be as possible little use. This allows the embodiment according to claim 7. With her can the horizontal articulation of the spindle bearing serve to arrange the prop in a horizontal position in front of the foundation and the swiveled footplate first to connect with the foundation. This work does not need crane help, only then again is needed when the prop is erected becomes. Of course, it can be used as an but also as a vertical building support in Structure are used.

With many bridge constructions, first of all Bridge foundations made before the formwork with the help of the scaffolding construction. The bridge bearings have these foundations and therefore have relatively narrow tops for setting up the bridge storage near Building supports. According to the claim 8 invoice. This is because the needs for Installation of the necessary area of the bridge warehouse only to be as big as the relatively small areas Head and foot plates as they are within the Projection of the cladding truss panels arranged are.

Attention also needs special attention and the protection of the head and foot spindles. These are largely protected by cladding tubes. The cladding tubes must, however, the vertical Forces are transmitted to the barrel nuts and are therefore also the abutments of the scaffolding posts. in the Claim 9 will do this in a simple manner Box cross-section of the cladding ensures that Walls a divergent strut of the cladding truss panels to the base of the rising Carry modular scaffold tubes.

On the other hand, it should be possible to reach the spindles the vertical forces essentially without Can absorb buckling stresses. With the Features of claim 10, this is possible because on the one hand, securing the position of the spindles in the cladding tube with at least one the cladding tube and the Cross bolt passing through the spindle ensures that the spindle with the main direction in particular vertically arranged building supports correspond axially, on the other hand the game of the cross bolt in the cladding tube and in the spindle, albeit a small one Relative adjustment of spindle and cladding tube enables the small deviations of the spindle axis compensate from the main direction of the prop can.

If you have several position safeguards of this type provides the features of claim 11, the order Arc angles are offset from each other, can the respective truss panel opposite the foot or Arrange the head plate offset by such arc angles. This has the advantage that the foot plates each according to arrangement and size of the foundation area in an optimal position can be brought in which they rest completely on the foundation.

The storage reproduced in claim 12 Spindle on the foot or on the head plate favorable for the execution in the desired Welded construction. The foot plates According to claim 13, preferably several anchor holes exhibit through the in the foundation Anchor inserted and the base plate screwed to the anchor can be. You can then also easy to assemble as when dismantling the scaffolding structure remove again from the foundation.

The scaffolding elements are natural in the scaffolding construction of the invention widely used. You must therefore easily access each required heights of the yoke beams can be set can, d. H. the distance between the foundation and bridge the yoke beams. The necessary There is variability in the length of the prop in a simple manner from the features of the claim 14. Then the modules can be used individually for one Use scaffold support or several to one Screw the scaffold support. The module length represents on the connecting plate distance, so that a constant Distance of the connecting plates guaranteed is. For this purpose, the features of claims 15 and 16 expedient.

Modular scaffolding, which according to the invention the rising Deliver stems of construction supports, use for the mutual connection of scaffold tubes Pipe clamps, each of which is to be connected Pipes is assigned to a pipe clamp and the two clamps screwed together Connection joint for the other of the also screwable Has pipe clamps. If the scaffolding element has a pipe clamp, such as e.g. can also be the case with screed consoles these scaffolding elements are screwed to the modular scaffolding tubes will. The invention has this advantage according to claim 17. This also spatial Structures possible.

Such structures require precise adjustment the angular position of the building supports and that of pipe clamps connected horizontal or diagonal Scaffolding elements. This is with the characteristics of the Claim 18 relieved because of the markings specify the letter of the pipe clamps and therefore a subsequent adjustment is not necessary is. Such adjustments can be made with realize the features of claim 19.

The building construction shown in the detail in FIG. 2 1 works with reusable rising Construction supports, the details of which are most clear emerge from the representation of FIG. 1. The building supports are equidistant from each other in two rows 2 and 3 each on foundations 4 and 5 set up and with these screwed. The building supports 5 and 7 are one below the other with horizontal struts 8 to 10 above and 11 up to 13 shear-resistant struts. The building supports 14 to 16 of the second row are the same Like the construction supports of the first row with each other strives. Besides, they are each other neighboring building supports 5, 14, 6, 15 and 7, 16 between the two rows 2, 3 in turn as in 18 and 19, for example, shown twice and at 20 and 21 simply braced at the top and bottom. A of the two rows, namely the one labeled 3 Row of supports carries side brackets 23, 24, 25 as a cantilever of a scaffolding, which one Screed flooring 26, 27 as a step on the brackets has and with a double back railing 28, 29 is provided. The back railing is in turn as shown at 30 with the Struts struts.

2 are identical. The example of the building support 5 according to FIG. 1 is recognizable that four continuous modular scaffold tubes 31 to 34 form the stems of each prop. In predetermined distances of approx. 50 cm are on the Cylinder surfaces of connecting plates 35 and 38 welded on. Those that can be connected to the modular scaffolding tubes Scaffolding elements, d. H. the struts 8 to 13 and 18 and 19 and 30 carry at the ends of their tubes 42 couplings 39, which from one above the rim of the swing-in hook 40 and one Wedge 41 are formed, which the hook 40th out of the box. The modular scaffold tubes 31 to 34 have so far been used for scaffolding, in which they can carry relatively low loads to have. In the scaffolding 1 carry in general with a diameter of 48.3 cm Module scaffolding tubes 31 to 34, however, together usually extraordinarily high, in particular vertical support forces from z. B. from the Use of scaffolding 1 as a support structure for bridge formwork. Wear it the supports of each row 2, 3 one each Yoke beams 42, 43 on which transverse beams can be arranged that support the formwork skin.

That is why the modular scaffold tubes are part of a framework 44, whose infills from stiffening frames 105 to 108 and those arranged above and below Truss panels 49 and 50 are formed. These infills are always outside the connecting plate 35 to 38 and are the action the hook 40 and wedges 41 withdrawn, so that these parts can be operated freely. In the building supports 5 to 7 as well as 14 and 16 the frames are therefore between the connection plates, while the lower truss 49 below the lower connecting plate 35 are arranged.

The multiple struts 8 to 13 in the top and lower levels of the building structure 1 achieved that on the corners of a square arranged modular scaffold tubes "on gap" stand because one of the two levels, each one two diagonally aligned modular scaffold tubes contains, parallel to the direction of the horizontal struts runs.

The details of the truss panels are given in the 3 to 5, in which the lower truss 49 is shown. she has a generally square plan, the four Corners 50 to 53 are broken by bevels. Four struts 55 to welded in the corners 57 carry those acting on the truss panel vertical forces on a cladding tube 58, the at 59 penetrates the plate. The cladding tube is there from a square hollow profile and rests with its bottom 60 on an adjusting nut 61, the rotated in both directions via a handle 61 can be. The adjusting nut 61 rides on one Spindle 62 (Fig. 7), which has a transverse bore 63 on has lower end. This takes the pin 64th a horizontal joint 65 on both sides in an articulated bushing 66 is mounted. It serves each a bearing plate 67, 68 on a plate 69, which can be used as a base or head plate 70 (Fig. 1). The bearing plates are each with two Support plates 71, 72 additionally attached and held. As can be seen from Fig. 1, the foot and the top plate up to the truss plates 49 identical. This allows the construction supports to be used as required with their plates 49 pivoted through 180 ° deploy. The horizontal joint enables also the use of the building prop as an inclined prop and also allows the support to be folded down the vertical to the horizontal and vice versa, while the foot plate 69 is horizontal.

In accordance with the framework panels standing upright in the corners 50 to 53 Mandrels with a frustoconical tip 72 to 75. They extend into the inner cylinders of the modular scaffold tubes 31 to 34, the rest of the assigned to them The top of the plate is welded on.

The head and foot spindles have the same travel ranges, namely about 25 cm and thus half the distance of the Connection plate 35 to 38, so when used stepless height adjustment of both spindles about the amount of a connecting plate distance is made possible. That is enough to support the struts to adjust the height with sufficient accuracy. As can be seen, inter alia, from FIG. 5, are the head and foot plates 69 and 70 within the projection of the truss panels 40 and therefore have a much smaller outline than this on. They are therefore suitable for the edition on narrow surfaces of the foundation, as for example through the top flange of the foundation beams 4 and 5 are indicated. The head and foot plates but also have holes 76 to 78 for Screws or anchor bolts with which they are on the foundation can be screwed.

So that the cladding tubes 58 when the Do not turn the adjusting nuts 61 in relation to the spindles is a bearing lock for the spindles 62 provided in the cladding tubes. On the one hand, it exists from several transverse bores 79 to 81, which enforce the hollow spindle 62 (Fig. 7) and out Longitudinal slots 82 which are the opposite Push through wall segments 83, 84 of the cladding tubes 58 (Fig. 6) and also from a screw or Wedge pin 85 (Fig. 5). The slots have each one over a travel of the spindle 62 Length. The multiple holes 79 to 81 allow different rotational positions of the truss panels 40 compared to the head and foot plates 69 and 70, see above that with the head and foot plates the cheapest Land use of the foundation sought can be.

While the building supports 5 and 7 and 14 and 16 in Embodiment of FIGS. 1 and 2 from continuous Module scaffold tubes 31 to 34 and a continuous Truss exist to the height between the founders 4, 5 and 40 and 43 with a Bridging the length of the column belongs according to the exemplary embodiment 8 to 16 to this scaffolding construction one or more sets of modules, that differ from each other in their length, that follow a certain grid, where the respective support length except with the spindles 62 on the head and foot plates by choosing appropriate ones Modules can be set. Hereby it is possible while maintaining the described Advantages of building construction 1 practically every possible column length in a simple manner to realize.

The module 85 according to FIG. 8 has the shortest length and accordingly shows rising modular scaffold tubes 86 to 88 between two truss panels 89 and 90 on. These correspond to those in connection with the Construction supports 5 and 7 as well as 14 and 16 mentioned truss panels essentially, including that in mandrels 91 to 94 arranged at the corners are bores 85 to 98, which are for screwing with adjacent truss panels Modules or truss panels and spindles as well Base or head plates according to FIGS. 3 to 5 are used. In the middle of the truss panels 89 and 90 is therefore a circular recess 99 is also provided, through which the cladding tube can be passed.

To the infills of the building supports 5 and 7 and 14 and 16 in addition to the truss 49 Head and foot spindles also frames 100 to 104. These consist of four in the frame corners the module scaffold tubes 31 to 34 welded rigidly Frame members 105 to 108, wherein in the Infill frames 100 and 102 another diagonal Frame member 109 is welded. A frame 103 without a diagonal also serves to fill in the module 85 in the middle between the truss panels 89 and 90.

Such a frame 103 is also used for the infill of the module 110 shown in FIGS. 9 to 11 is. The frame members 111 to 115 are identical and correspond to the diagonal 109. It is about around sheet metal cutouts, each with a longitudinal bead 116, the example of the frame member 115 is shown and the stiffness of the Sheet cutout improved. The length of the module 110 corresponds approximately to the distance between the connecting plates 35 to 38 in the exemplary embodiment of FIGS. 1 to 7. Therefore there is between the frame and one of the two truss panels 117 and 118, which the Truss panels 89 and 90 of module 85 correspond on the four modular scaffold tubes 119 to 122 each a connecting plate 123 to 126.

The module 127, on the other hand, has a length that corresponds approximately to the distance from three connection plates. It is with a frame 100 above that superimposed connection plate levels 128 and 129 and with a further frame 100 between the Connection plate levels 128 and 129 and with one upper and lower truss panels 117 and 118 fanned out.

Another module 130 essentially corresponds the lengths of the supports 5 and 6 and is like this educated. It is only at the ends Construction support construction with truss panels 117 and 118 canceled and accordingly has none Spindles on.

The use of the modular scaffold tubes in the supports 5 and 6 and modules 85, 119 and 130 also has the advantage that you can on the rising pipes further scaffolding elements between the connection plates can connect with pipe clamps. In the embodiment 2 is that for the consoles 22 to 24 of the scaffolding possible, what in detail is not shown. Since one for such scaffolding elements needs precise alignment the pipes are provided with longitudinal grooves, which in turn offset from each other by arc angle are and with corresponding specializations interact on the inner cylinders of the pipe clamps.

The support tubes 31 to 34 were arranged so that their sleeve spacing in the horizontal Diagonal of the half-timbered panels 40 is 500 mm or a multiple of this value, i.e. u. a. the height distance of the plates 35 to 38 and thus correspond to the module of the scaffold. So it is possible the logical required for modular scaffolding To ensure grid dimension. Then differ the lengths of the horizontal bars also around this module or a multiple of its value. This has considerable advantages in the coupling several supports.
