Description

Technical Field

[0001] The utility model belongs to the technical field of building support structures, and in particular relates to a foldable and recyclable triangular truss. Background Art

[0002] In modern building design, designers often control patios or suspended beams and slabs in the facade design in order to pursue the effect of the building's facade, so as to enhance the viewing experience of the building's facade, but it also brings difficulties to the construction.

[0003] At present, for the construction of large-span high-altitude connecting beams, the formwork construction is generally carried out by laying inclined I-beams on the walkway corridor, or setting up steel trusses at the bottom of the connecting beams as the formwork foundation of the high-altitude connecting beams.

[0004] On the other hand, the existing technical solution is to build a steel structure platform on the bottom floor before construction. The horizontal steel beams of the steel structure platform are connected to the main structure through pre-embedded parts. After the strength is met, the main and secondary beams of the platform and the maintenance structure are welded to serve as the supporting platform for the cantilever structure beam and slab formwork and the hoisting steel column, thereby solving the problem that the cantilever structure cannot be constructed with formwork at high altitude.

[0005] The Chinese invention patent with invention patent publication number CN116005935A and publication date 2023.04.25 discloses a prefabricated composite composite connecting beam triangular support protection integrated frame, the structure includes two cantilevered triangular support frames installed on two relatively shear walls and a walkway plate for connecting the two cantilevered triangular support frames. The cantilevered triangular support frames are used to bear the vertical load of the connecting beam and the live load of the construction workers. The cantilevered triangular support frames are composed of two tripods and multiple connecting plates. The multiple connecting plates are fixedly connected to the tops of the two tripods, and two sets of guardrails and a supporting plate are installed on the multiple connecting plates.

[0006] The general structural principle of the assembled bracket casting platform supported by inclined rods in this invention patent is as follows: the present invention optimizes the connecting beam into a prefabricated composite beam, which is hoisted to the cantilevered triangular support frame by a tower crane, connected to the main structure with reserved steel bars, and finally concrete is cast on the upper part; this method has the advantages of fast construction speed, low cost, high safety, and low requirements for tower crane hoisting.

[0007] However, the support structure still has at least the following deficiencies during actual use, in other words, these are the technical problems that the present utility model aims to solve.

[0008] 1. The cantilevered triangular support frame is not easy to disassemble after use and is easily blocked by concrete, which affects the disassembly efficiency and the safety of construction workers.

[0009] 2. The cantilevered triangular support frame has a complex structure and is not convenient for transportation. During installation, it is necessary to distinguish each installation part in advance, which increases the difficulty of installation.

[0010] Therefore, in summary, there is an urgent need for a new type of support structure that is easy to disassemble and foldable for transportation. Utility Model Content

DETAILED DESCRIPTION

[0032] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0033] As attached Figure 1-6 As shown, a foldable and recyclable triangular truss includes an upper mounting plate unit 1 for connecting a wall a, a horizontal support plate unit 2 plugged into the upper mounting plate unit 1, a vertical support plate unit 3 hingedly arranged on the horizontal support plate unit 2, and an inclined folding rod unit 4 whose two ends are respectively hinged to the horizontal support plate unit 2 and the vertical support plate unit 3.

[0034] In this embodiment, the foldable and recyclable triangular truss is used as the formwork foundation of the high-altitude connecting beam in the facade design. The upper mounting plate unit 1 is used to connect the wall a. The horizontal support plate unit 2 is fixed to the wall a through the upper mounting plate unit 1 and extends outward by a certain length to bear the weight of the cast walkway b. The vertical support plate unit 3 and the inclined folding rod unit 4 form a triangular stable relationship with the horizontal support plate unit 2. The vertical support plate unit 3 not only supports the downward force of the horizontal support plate unit 2, but also fixes the lower end of the inclined folding rod unit 4, and transfers the horizontal support plate unit 2 borne by the inclined folding rod unit 4 to the wall a, so that the overall structure of the foldable and recyclable triangular truss is firm and has high overall strength.

[0035] In addition, the upper mounting plate unit 1 is connected to the wall a by means of expansion screws or reserved holes, etc., in order to bear the supporting force of the horizontal support plate unit 2. The horizontal support plate unit 2 and the upper mounting plate unit 1 are fixed by plugging. On the one hand, during the installation process, the connection method is simple and convenient; on the other hand, during the disassembly process, it is usually necessary to use a tower crane to transport the disassembly personnel to a suitable position for disassembly work, and the casting walkway b above can easily block the disassembly personnel and angles, causing disassembly difficulty. The plug-in method can avoid this problem. It is only necessary to remove the horizontal support plate unit 2 from the upper mounting plate unit 1. It is safe and fast, and meets the support strength.

[0036] Finally. The horizontal support plate unit 2 and the vertical support plate unit 3 are shell-shaped rigid structures with a U-shaped cross-section. The vertical support plate unit 3 reinforces and connects the two ends of the horizontal support plate unit 2 and the inclined folding rod unit 4, making the overall structure more stable. At the same time, the connection between the vertical support plate unit 3, the horizontal support plate unit 2 and the inclined folding rod unit 4 is connected and fixed in a hinged manner. During transportation, the inclined folding rod unit 4 can be folded and folded into the horizontal support plate unit 2, which is convenient for transportation and each component is not easy to lose. In order to further ensure the fixity of each hinge point when in practical use, a locking nut can be set at the hinge point, and the locking nut only needs to be removed during disassembly.

[0037] The upper mounting plate unit 1 includes a mounting plate 101 with holes, a connecting side plate 102 arranged on the mounting plate 101 with holes, and a supporting vertical plate 103 arranged on the connecting side plate 102 .

[0038] In this embodiment, the function of the perforated mounting plate 101 is to be connected to the wall a, and the connecting side plate 102 and the supporting vertical plate 103 are used to limit and clamp the plug board 201 and withstand the force of the supporting block 202. In order to further prevent the plug board 201 from being detached due to force, a reinforcement structure can be further provided on the connecting side plate 102 for clamping the plug board 201.

[0039] The horizontal support plate unit 2 includes a plug-in plate 201 inserted into the connecting side plate 102 , a support block 202 disposed on the plug-in plate 201 and used to connect the supporting vertical plate 103 , and a supporting horizontal plate 203 disposed on the supporting block 202 .

[0040] In this embodiment, the plug plate 201 is inserted into the slot enclosed by the connecting side plate 102 and the supporting vertical plate 103, and the plug plate 201 and the supporting horizontal plate 203 are connected by the supporting block 202. The function of the supporting horizontal plate 203 is to bear the force of the casting walkway b. When in use, a plurality of the foldable and recyclable triangular trusses are relatively arranged on the wall a, and the adjacent supporting horizontal plates 203 are reinforced by the connecting beam plate 206 to ensure the stability and supporting force of each foldable and recyclable triangular truss, and then construction is performed on the supporting horizontal plate 203 and the connecting beam plate 206.

[0041] The vertical support plate unit 3 includes a vertical reinforcement plate 301 hingedly arranged on the support horizontal plate 203, and a lower end fixing plate 302 arranged on the vertical reinforcement plate 301 and used for connecting to the wall a.

[0042] In this embodiment, one end of the vertical reinforcement plate 301 is hingedly set on the side of the supporting horizontal plate 203 close to the wall a, and the other end is connected to the inclined rod 401, so that the foldable and recyclable triangular truss forms a triangular stable structure, and the lower end fixing plate 302 is used to connect the lower end of the vertical reinforcement plate 301 to the wall a.

[0043] The tilting and folding rod unit 4 includes two tilting rods 401 which are respectively hingedly arranged on the supporting horizontal plate 203 and the vertical reinforcing plate 301 and are hingedly arranged with each other, and a hinged fixing sleeve 402 which is arranged between the two tilting rods 401 .

[0044] In this embodiment, the tilting rod 401 is used to support the force on the supporting cross plate 203 away from the wall a, preventing the supporting cross plate 203 from being deformed by the force, and ensuring the supporting strength. The hinged fixing sleeve 402 is used to fix the two tilting rods 401. The two tilting rods 401 are rigid structures. The function of the hinged fixing sleeve 402 is to fix the connection between the two tilting rods 401 to ensure the supporting strength.

[0045] The horizontal support plate unit 2 further includes a telescopic sleeve 204 sleeved on the support horizontal plate 203 , and a limit nut 205 disposed on the telescopic sleeve 204 and used for adjusting the length of the telescopic sleeve 204 .

[0046] In this embodiment, the telescopic sleeve 204 is sleeved on the supporting horizontal plate 203, and the telescopic length thereof is limited by the limiting nut 205, so as to meet the requirements of high-altitude connecting beams of the wall a at different intervals.

[0047] The tilting and folding rod unit 4 includes two screw rods 403 respectively hingedly arranged on the telescopic sleeve 204 and the vertical reinforcement plate 301 , and an internal threaded tube 404 sleeved on the screw rods 403 .

[0048] In this embodiment, due to the setting of the telescopic sleeve 204, the deformation and force mode of the horizontal support plate unit 2 change. In order to prevent the telescopic sleeve 204 from being deformed due to force, two screws 403 are set, and the internal threaded tube 404 is sleeved on the screw 403. The two screws 403 are screwed to the internal threaded tube 404 in reverse, so that the sleeved internal threaded tube 404 can simultaneously control the extension and retraction of the two screws 403, thereby adapting to the force changes brought about by the extension and retraction of the telescopic sleeve 204, ensuring the supporting strength of the inclined folding rod unit 4. During transportation, it is only necessary to reduce the extension distance between the internal threaded tube 404 and the screw 403 to the minimum, and remove the hinge point at one end so that it can be folded into the horizontal support plate unit 2 to meet the folding and transportation requirements.

[0049] There are two internal threaded tubes 404 , and the tilting and folding rod unit 4 further includes a limiting connecting block 405 arranged between the internal threaded tubes 404 .

[0050] In this embodiment, since the two screw rods 403 are rotated simultaneously when the knob of the internal threaded tube 404 is turned, the telescopic accuracy is insufficient. Therefore, two internal threaded tubes 404 are provided to respectively control the two screw rods 403, so as to achieve higher telescopic accuracy. The limiting connecting block 405 connects the two internal threaded tubes 404, and an I-shaped connecting steel nail or a structure that does not affect the rotational freedom of the two internal threaded tubes 404 can be used for connection, thereby ensuring the structural strength without affecting the telescopic requirements.

[0051] The tilt-folding rod unit 4 further includes a pin shaft 406 disposed on the screw rod 403 and used for connecting the vertical reinforcement plate 301 .

[0052] In this embodiment, the pin 406 serves to detachably hinge the screw 403 and the vertical reinforcement plate 301. Since the screw 403 is sleeved with the internal threaded tube 404, it is difficult to fold them. In order to facilitate transportation and disassembly, the pin 406 is provided. When in use, the pin 406 is tightened for support. When disassembly, the pin 406 is removed, and then the screw 403 and the internal threaded tube 404 are turned to the shortest and folded into the horizontal support plate unit 2 for easy transportation.

[0053] The upper mounting plate unit 1 further includes a fixed bottom plate 104 disposed at the bottom end of the connecting side plate 102 .

[0054] In this embodiment, the fixed bottom plate 104 serves to reinforce the connecting side plates 102 and the supporting vertical plates 103 , and can also support the plug board 201 to a certain extent.

[0055] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
