AI Technical Summary
In existing technologies, plain concrete columns and scaffolding cannot be fully compacted with the floor slab when supporting the floor slab, resulting in excessive stress on the floor slab when bearing loads, which can easily lead to damage.
A floor slab back-support device was designed, including a support rod and a support plate structure. The distance between the support plate and the floor slab is adjusted by a threaded connection and a limiting structure to make it press against the floor slab. Combined with the interference fit of the wedge structure and the base, the support device is ensured to be firmly pressed between the floor slab and the ground.
This design achieves complete compaction of the support device between the floor slab and the ground, preventing damage to the floor slab due to excessive load and improving the stability and ease of assembly and disassembly of the structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction, specifically to a floor slab back-top support device. Background Technology
[0002] In the current construction industry, taking the construction of upper and lower floors as an example, due to factors such as site safety areas, the materials for the construction of the upper floor need to be piled up in a certain area on the ground floor (i.e. the floor slab of the lower floor) to wait for assembly. As a result, the crane and materials will exert a large load on the floor slab of the lower floor, which may cause damage to the floor slab.
[0003] To prevent the upper-level cranes and stacked materials from putting excessive loads on the lower-level floor slabs and causing damage, the common practice is to install plain concrete columns or scaffolding at appropriate locations in the lower-level building to support the floor slabs.
[0004] However, due to their fixed length, plain concrete columns and scaffolding often have gaps with the floor slab when used for backfilling in buildings. This results in the plain concrete columns or scaffolding not being able to be firmly anchored to the floor slab, thus causing excessive stress and damage to the floor slab when it bears the load. Utility Model Content
[0005] The purpose of this utility model is to provide a technical solution for a floor slab back-support device to address the shortcomings of the existing technology. Its overall length can be adjusted according to the actual distance between the floor slab and the ground, thereby achieving a firm connection between the floor slab and the ground.

[0009] The top of the support rod is movably connected to a support plate structure for abutting against the floor slab. The support plate structure can move up and down along the support rod. Controlling the displacement of the support plate structure can adjust the distance between it and the floor slab, thereby achieving tight abutment between the support plate structure and the floor slab.
[0010] By adopting the above technical solution, the support rod is used to form a support between the floor slab and the ground. When actually supporting the floor slab and the ground, the construction workers can adjust the support plate structure to move it up and down along the support rod to shorten the distance between it and the floor slab until the support plate structure is pressed tightly against the floor slab. This can achieve the effect of the entire support device being firmly supported between the floor slab and the ground, avoiding the problem of excessive stress and damage to the floor slab when it is not properly supported.

[0012] Further, the limiting structure is movably connected to the support rod through a thread.
[0013] Further, the support plate structure is movably connected to the support rod through a thread.
[0014] Further, one end of the support rod is provided with a base for fixedly connecting the support rod to the ground.
