Support structure for building cladding

030026/0 7 50

5062-12 g

The present invention relates to supporting structures for supporting building Cladding at different heights, for example of shuttering for concrete slabs, as well as of Cladding associated with these concrete slabs, concrete beams lowered.

Although the present support structures may be used for supporting all sorts of items that must be supported, they are particularly designed for supporting the shuttering for concrete slab floors or concrete slab ceilings, while simultaneously supporting the shuttering for lowered concrete beam which v formed together with the concrete floors / ground while the concrete for these puss floors is poured, with concrete slabs and concrete beams supported and supported until the concrete becomes self-supporting.

A newly formed concrete slab has to be supported for a comparatively short period of time, usually only for a few days , whereas the lowered concrete girders normally have to be supported for a longer period of time, e.g. B. must be supported over the course of 14 days. As a result, whoever tied the formwork for the concrete slabs for comparatively longer periods of time.

Since this type of construction usually occurs in relatively large structures, it is advantageous to move the concrete formwork from one area to another as soon as the concrete can be poured. The longer the formwork remains in the position in which it supports the concrete at one point, the greater the number of formwork required, which must be available for the construction work. It is therefore possible to move the concrete slab formwork from a given location during a

030026/0750

5062-12 Q

relatively short time to remove, reducing the number of concrete slab formwork required can. Obviously, this is a significant economic factor, given that surface area the cast concrete slabs are much larger than that the lowered concrete beam is.

Support pillars or support structures have been used for many years to support concrete slab formwork and formwork for sunken concrete beams. In order to be able to remove the concrete slab cladding as soon as the concrete slab became self-supporting, in the past the upper end of the pillar had to be loosened or loosened and removed in order to remove the concrete slab cladding. This also removed the support, with the concrete girder formwork being loosened. It was then necessary to tighten the existing supporting structure again or to build a new supporting structure to support the concrete girder for a longer period of time. This system was costly and time consuming, with the newly cast and relatively soft sunken concrete beams also being dangerously unsupported for a short period of time before they were re-supported.

According to the invention, these disadvantages are overcome by a supporting structure or a supporting pillar is proposed, which the formwork for the concrete slabs and the Support the formwork for the concrete girders connected to the concrete slabs simultaneously and independently of one another. This support pillar or this supporting structure is built in such a way that the concrete slab formwork without the support to disturb the lowered concrete beam can easily be solved and removed v / ground. In addition, each is a buttress or any supporting structure so lightweight that it can be placed in a horizontal position on the Pussboden can be assembled or assembled,

whereupon it can be raised like a ladder to its vertical position. Although the buttress is a simple one and light. 'construction, it is very well braced or stiffened, the bracing sections and the sections of the support pillar can be built or expanded quickly. The pillar or supporting structure consists of one or several of the same pillar sections, which are the same Height or can have different heights. If more than one height of the support pillar is provided, so can the said sections are quickly and easily connected to one another, the bracing of one section on the other hand, so that the support pillar represents an extremely stable construction in its erected position.

A support structure according to the invention can support building formwork at different heights at the same time, with the support structure according to the invention has at least one support section having a plurality of spaced-apart pairs of perpendicular legs, the legs of each pair being spaced from one another on opposite sides of the support section and horizontal rust ties extend between the legs of each pair of legs and on the legs of each Leg pairs are attached, while inclined cross braces between the legs of a pair of legs and the adjacent legs of another pair of legs extend on the same side of the Tragabschnitbes and to the corresponding Legs are attached and with horizontal raised concrete beams at opposite ends of the same are attached to the legs of each pair of legs in the vicinity of the upper ends of the latter legs to a Support building formwork at a first height that extends between these legs, while supporting parts in the

Referring now to Figures 1 through 12 of the drawings, numeral 10 indicates a support structure or buttress according to the present invention, which during the pouring of the concrete for a floor slab 12 and a integrally provided lowered support 14 is used, which depends from the floor plate 12 down to this Support elements. The support pillar supports the formwork for the panels and for the beams during potting of the concrete and continues to support it after the concrete has been poured. As soon as the concrete has hardened sufficiently is to be partially self-supporting, the formwork can be removed "elsewhere" for further use where appropriate, the buttress can be used to support the concrete for a further period of time. The support pillar shown here supports at one level a formwork 16 for a concrete beam cast in position, this casing consists of a base plate 17 and side parts 18. The right side of the buttress supports

030026/0750

5062-12

a panel formwork 22, which consists of a base plate 23, which consists of several lateral at a distance from each other arranged support beam 24 rests. The side part 18 of the support formwork 16 and all panel formwork 22 have been removed from the left side of the lowered beam so that the left portion of the buttress 10 directly supports the plate 12 in a supported position. Since the carrier 14 is well supported at this point is, the re-support of the plate 12, which is so close, is usually not absolutely necessary.

The supporting pillar or the supporting structure 10 consists of one or more supporting sections lying one above the other, in the illustrated embodiment, the buttress has a lower support portion 30 and the like has upper support section 31. These support sections can have the same height or different heights, as shown, exhibit. Since these support sections with the exception of their corresponding heights are the same, only one of them, namely the section 30, will now be described in more detail, the the same reference numerals are used for the two support sections.

The support section 30 includes a pair of side spaced apart mutually arranged legs 35 at one end and another pair of lateral spaced apart and like legs 37 at an opposite end. These legs are preferably tubular. The legs 35 are supported by suitable struts, such as a plurality of horizontal grate ties 40, the extend therebetween and on opposite ends in any convenient way, such as. B. by Welded, as shown in Fig. 1, are attached, provided at a distance from one another and connected to one another, wherein

030026/0750

5062-12

the legs 37 in a similar manner by struts, such as z. B. are provided by the horizontal grate sleepers 40 at a distance from each other and connected to each other. The number of Rostschwelleri between each pair of legs depends on the height of the buttress section and the individual choice. As shown in Figure 1, the lower buttress section

30 three horizontal grate sleepers, while the upper support pillar section 31 only two such. Has host thresholds. These rust sleepers not only act as braces or Stiffeners for the support pillars, but also planks or floorboards can be arranged on it, which act as platforms to serve for the workers. Some or all of the grate sleepers 40 can optionally be provided with angle braces 42 are, which extend from it to adjacent legs 35, 37 to support the bracing and stabilization of the Extending buttress.

Each buttress or supporting structure is braced in the form of cross struts 35 »36, which are between legs 35 and 37 extend on either side of the buttress as shown in FIG. These cross braces are preferably detachably connected to the support pillar legs, appropriate connecting parts for this to be described below are. In the illustrated embodiment according to the invention, additional struts extend in the form of a pair of central cross braces 48 and 49 between the legs 35 and 37 of the upper support pillar section

31 and the legs 37 and 35 of the lower support pillar

cut 30 on each side of the buttress. The upper ends of the struts 48 and 49 are preferably connected to the legs of the support pillar by the same connecting parts as the lower ends of the struts 45 and 46 of the upper support pillar section, the lower ends of the center struts 48 and 49 with the legs of the lower support pillar section through the same connecting parts as the

030026/0750

upper ends of the struts 45 and 46 of the latter support pillar are connected, as shown in FIG.

The corresponding legs 35, 37 of the support pillar sections 30 and 31 are aligned and detachable in the steering direction connected together so that they in effect form legs extending from the lower end to the upper end of the Support pillars extend. Fig. 3 shows a preferred embodiment a connecting device between the adjacent ends of two support pillar legs lying one above the other, such as B. the leg 35.

The lower end of the upper leg 35 is releasably connected to the upper end of the lower leg 35 by a connecting part. This connecting part has a coupling pin 57, which has a diameter such that it engages in the adjacent ends of the support pillar legs and is slidably seated therein. The coupling pin has a collar 58 centered between its ends, with Kadiallö'cher 59 and 60 extending through the pin near the opposite sides thereof. The ends of the coupling pin are provided with bevels 62 for ease of assembly or assembly. In the assembled state, the coupling pin 57 sits in the adjacent ends of the two aligned legs 35, these ends being supported against the collar 58, which serves as a bearing therebetween. This coupling pin is preferably slightly smaller in cross section than the legs in which it sits. In this case, depressions 63 are impressed inwardly in each leg so that the pin sits therebetween. These recesses hold the peg in its correct position, while the legs may be slightly inclined relative to one another during assembly to facilitate the erection of one pillar section over another.

A number of equally spaced holes 64 are provided which extend through each buttress chenk-el extend through it, with most of these Holes by a predetermined distance, for example by 152 mm (6 in.), Spaced apart from each other. In any case, the holes at the opposite ends of the leg are in spaced 70 mm (2 3/4 in.) from their respective ends. The collar 58 of the coupling pin 57 in this embodiment has a thickness or thickness of 12.5 mm, so that when the buttress legs are assembled the holes near the ends of the legs are 152 mm apart.

The holes 59 and 60 of the pin 57 are provided at a distance of 152 mm from each other, so as to correspond with holes 64 in the Align near the ends of the buttress legs in which the peg sits. A U-shaped connecting tenon or pin 66 has arms 67 and 68 which extend from a base 69 through the aligned holes of the buttress legs and the coupling pin extends therethrough. The base 69 of the U-shaped connecting pin acts as a handle around it for a person to enable the connecting pin to be inserted or removed. The base 69 is preferably bent inward, in order to form a stop 70 which comes into abutment or in contact with one of the support pillar legs, in order thus to limit the inward movement of the base when the connecting pin is inserted into the leg holes will. It should be noted here that the arm 68 is somewhat longer than arm 67 so that the former can be partially inserted into aligned holes whereas the latter always is still outside the thighs. The connecting pin on the arm 68 can then be pivoted about the arm 67 align with the thigh holes into which the latter arm is to be inserted, arm 67 is nearby the free end of the same perforated, thus a nail

or a key bolt or cotter pin 70 to receive after the arms have been passed through the aligned holes to prevent the connecting pin from accidentally to get out of its position in which the buttress legs are attached to one another.

A jack or screw jack assembly 72 is provided at the lower end of each buttress leg 35, 37, see FIG 1, 2 and 12. In this embodiment, each screw jack assembly has an extension tube 74 which slidably seated within the lower end of a buttress leg, as well as a lifter 75. This lifter has a screw spindle 77 »which can be slidably or displaceably seated within the extension tube 74, with one Nut 78 is screwed onto the screw spindle. This nut has a body with the same width or width or the same diameter as the extension tube, and also a handle 79 that connects to the lower surface is connected and protrudes laterally from the lower surface. The extension tube 74 is at rest on the screw nut 78 in such a way that when the latter is turned up or down on the screw spindle 77, the support pillar leg is raised or lowered accordingly. One end of the screw jack's screw spindle sits in an I.Iuffe 80, which is provided on a bearing plate 81, which may rest with one end on an appropriate support 82 and on it, for example with bolts, nails, screws or the like can be attached. The support 52 can be designed in the form of a support part or in any other suitable manner will. An arrangement 83 to be described below will be and from a nut and from one There is a screw bolt, it is shown how it connects the bearing plate to a support 82 in the form of a support beam.

The extension tube 74 is releasably attached to the lower end of the leg 35 by a connecting pin 66, which is preferably is arranged with its long arm 68 above its other arm 67. This peg extends through a selected one Pair of holes 64 in the buttress leg and through a hole 86 in the extension tube extending from the upper end is provided at a distance ^ and is aligned with one of the holes 64, with a half-hole 87 in said upper End of the extension tube is provided. The extension tube can be adjusted vertically or in terms of height relative to the leg will. The extension tube allows rough adjustment the effective length of the buttress legs, while turning the nut 78 on the screw spindle allows fine adjustment or fine adjustment.

The spacing of the hole 86 and the half-hole 87 in the extension tube 74 is the same as that of the holes 64 in the buttress legs, see Fig. 12. With this arrangement, the end of the long arm 68 of the connecting pin 66 can be partially inserted into a hole 64 in the buttress leg in which the extension pipe has been inserted. When the end of the tube engages this trunnion arm, the tube can be rotated until the trunnion arm falls down into the half-hole 87, the hole 86 of the extension tube being aligned with a hole 64 of the leg, causing the two arms of the trunnion to pass completely through the leg and the extension tube can be inserted through »The use of the half-hole thus serves to reduce the assembly time of the extension tube to a considerable extent.

The extension tube 74 can optionally be omitted. In this case, the screw spindle .77 sits slidably or displaceably in the support pillar handle 35 » , the latter

In this case, is shown in Fig. 12 with broken lines Stabilizer 88 shown on the top end jack screw spindle 77 attaches and sits slidably within the buttress leg to prevent the screw stem portion from wobbling therein to belittle. In some cases, both the extension letter can be used as well as the screw jack 75 are omitted, with a tube (not shown) which is too short and has the same diameter as that of the extension tube 74 would sit in the lower end of the support pillar leg and the Iluffe 80 of the bearing plate 81, wherein said leg rests on the bearing plate at the same time.

A jack assembly 92, which is similar to jack assembly 72, is optionally attached to the top of the buttress leg intended. The lifter assembly 92 may include an extension tube 94 that connects to the extension tube 74 corresponds, wherein a lifter 95 is provided with a nut 96, which on the screw spindle 97 of the lifter 95 is screwed on. The upper end of the screw spindle 97 is in an internally threaded socket 99 a Bearing plate 100 screwed in, which is similar to the bearing plate 81. If the lifter assembly 72 is omitted, then the adjustment of the lengths of the support pillar legs is achieved by means of an upper lifter assembly 92. The extension tube 94 can be omitted if necessary. But if the extension tube 94 is used, the lower end is this Extension tube releasably connected to the upper end of the support pillar leg by a connecting pin 66, while the upper end of the extension tube on the lower Section of the screw spindle 97 is seated and is supported against the screw nut 96.

In reference to on Pig. 9 it can be seen that the bolt head 128 with rounded, diagonally opposite corners 130 and with diagonally opposite square corners 131 is provided. The rounded corners 130 allow the bolt 126 to be rotated in a direction around the head 128 to rotate its cross-sectional position, whereas the corners 131 by engaging the side walls of the support beam enlargement 118 Prevent the bolt from turning any further. The corners 131 thus serve as limit stops rotation of the bolt head after inserting the head through the support beam slot 116. Here is to Note that the sleeve 99 of the plate is centrally located immediately below the support beam 105, "so that the latter Support beam legs associated with the plate are also arranged directly below and in alignment with the support beam so that any possibility of overspeed torque due to misalignment is avoided. Please note that the bolts 83 of the bearing plate 81 are preferably the same as the bolts 126 when the support 82 is in the form of a beam is formed, which the support beam 105 is similar or the same. A pair of raised beams 135 extend each with a bar 135 between the two legs 35 at one end of the support pillar, while the other extends between the two legs 37 at the opposite end thereof. Can serve raised girders or joists can be of any lightweight construction, the joists or girders illustrated herein being those described above Support beams 105 are similar or the same. The raised beams are the same and with their corresponding buttress legs connected in any convenient manner.
