[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The embodiment of the present application discloses a retractable temporary support device.

[0030] Reference Figure 1 A retractable temporary support device includes a plurality of groups of support legs 1, which are arranged at intervals along the length direction of a steel frame beam 2. The steel frame beam 2 is an H-shaped steel beam consisting of a top plate 21, a bottom plate 22, and a connecting plate 23. The top plate 21 and the bottom plate 22 are arranged in parallel, and the two are fixedly connected by a connecting plate 23. In this embodiment, two adjacent steel frame beams 2 and two groups of support legs 1 are taken as an example. The number of support legs 1 in each group is two. The two support legs 1 in the same group are respectively arranged on the bottom plates 22 of the two steel frame beams 2. The support legs 1 and the bottom plates 22 of the steel frame beams 2 are detachably connected by bolts to facilitate the disassembly and assembly of the support legs 1. The two support legs 1 in the same group are provided with a retractable support member 3. The retractable support member 3 is connected to the two support legs 1 by a retractable adjustment member 4. A plurality of uniformly distributed members 5 are cross-arranged on the two retractable support members 3. The height of the retractable support member 3 can be adjusted by the retractable adjustment member 4 so that the uniformly distributed members 5 can support the floor deck 6.

[0031] When supporting the floor decking 6 with a large span, the two supporting legs 1 of the same group are respectively installed on the bottom plates 22 of the two steel frame beams 2 by bolts, the telescopic adjusting member 4 is installed on the telescopic supporting member 3, and then the telescopic adjusting member 4 is installed on the corresponding supporting leg 1, and the telescopic supporting member 3 is placed under the floor decking 6, and then the uniformly distributed member 5 is set on the telescopic supporting member 3, and finally the height of the telescopic supporting member 3 is adjusted by the telescopic adjusting member 4 so that the uniformly distributed member 5 abuts against the bottom of the floor decking 6 to support the floor decking 6. Compared with the existing support structure construction method, this solution does not require the construction of cumbersome steel pipe scaffolding, saving manpower and material resources, and its construction efficiency is high, saving construction period and reducing construction costs.

[0032] Reference Figure 1 、 Figure 2 The telescopic support member 3 in this embodiment includes a support beam 31 and a support tube 32. The cross-section of the support beam 31 is rectangular, and the support tube 32 is a rectangular tube that cooperates with the support beam 31. The support beam 31 is slidably inserted into the support tube 32, and by adjusting the length of the support beam 31 extending outward from the support tube 32, the length of the telescopic support member 3 can be adjusted. Its length can be freely adjusted to suit the use in different span working conditions.

[0033] Reference Figure 2 、 Figure 3The support tube 32 is threaded with a plurality of fastening bolts 33. In this embodiment, four fastening bolts 33 are used as an example. Each of the four fastening bolts 33 is disposed on the bottom wall of the support tube 32, making it easier for workers to tighten the fastening bolts 33. The four fastening bolts 33 are evenly spaced along the length of the support tube 32. Rotating the fastening bolts 33 secures the support beam 31 to the support tube 32. Depending on the length of the support beam 31 extending out of the support tube 32, the corresponding fastening bolts 33 are adjusted to tighten the support beam 31, further securing the support beam 31 to the support tube 32.

[0034] Reference Figure 2 、 Figure 3 The telescopic adjustment member 4 in this embodiment includes a lead screw 41 and an adjustment nut 42. In other embodiments, these may be replaced by a hydraulic cylinder. Bolt holes 43 are provided at the ends of the support beam 31 and the support tube 32 that are away from each other. The lead screw 41 is screwed into the bolt hole 43 to achieve a detachable connection with the support beam 31 or the support tube 32. The support leg 1 is provided with a mounting hole 44 for inserting the lead screw 41. When installing the lead screw 41 and the support leg 1, the lead screw 41 is inserted into the mounting hole 44 from top to bottom. The adjustment nut 42 is threaded onto the lead screw 41. The diameter of the adjustment nut 42 is larger than the diameter of the mounting hole 44, so that the adjustment nut 42 can abut against the support leg 1, thereby providing support for the telescopic support member 3. By changing the position of the adjustment nut 42 on the lead screw 41, the length of the lead screw 41 extending out of the mounting hole 44 can be adjusted, thereby adjusting the height of the telescopic support member 3.

[0035] Reference Figure 1 、 Figure 2 The uniformly distributed member 5 in this embodiment is a square timber 51, which is arranged crosswise with the support beam 31 or the support tube 32. The square timber 51 is arranged perpendicular to the support beam 31, which increases the stability of the overall structure. The square timber 51 is a long strip member with a rectangular cross-section, and the length is adjusted according to actual needs. The material is usually hard wood, which can withstand large loads and has good stability. An alternative feature of the square timber 51 can be a steel plate, which can also play the role of uniformly distributing the load, and its thickness and width are designed according to actual requirements. The support beam 31 and the support tube 32 provide support for the square timber 51, and the square timber 51 distributes the load evenly to the support beam 31 and the support tube 32, and disperses it to the entire temporary support device, ensuring the stability and reliability of the entire system. This design not only meets the construction requirements of steel truss floor slabs 6 of different spans, but also improves construction efficiency and reduces material and labor costs.

[0036] The implementation principle of a retractable temporary support device in an embodiment of the present application is as follows: by adopting the design of a retractable support beam 31 and a support tube 32, the length of the temporary support device is flexibly adjusted to meet the construction requirements of steel truss floor decking slabs 6 of different spans. At the same time, combined with the design of the height adjustment screw 41, the height of the entire temporary support device can be easily adjusted, which greatly facilitates the construction process and simplifies the construction process. This combination not only improves the adaptability and convenience of the temporary support device, but also enhances the overall stability and reliability of the support system, significantly improves construction efficiency and reduces construction costs. In addition, through the reasonable setting of the uniformly distributed parts 5, the uniform force on the floor decking slab 6 is further ensured, ensuring the reliability and safety of the entire temporary support device in actual application.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
