Supporting structures are needed during the construction of reinforced concrete slab bottom reinforcement to support it and improve its subsequent stability.

[0003] There are many types of such devices on the market today, which can basically meet people's needs, but there are still some problems: usually, it is necessary to use stirrups, spacers, positioning bars, and rebar tying (wire bundling) to tie and fix the horizontal or vertical super-strong rebars used in construction. Since the quality of tying is greatly affected by human experience, it is easy to cause the rebars to shift or not be fixed firmly. In addition, when using it, the bottom of the rebar will be inserted into the concrete, which increases the time required to tie the horizontal or vertical super-strong rebars. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom reinforcement support structure for reinforced concrete slabs, in order to solve the problem that the device proposed in the background art usually requires the use of thin steel bars to tie and fix the horizontal or vertical super-strong steel bars used in construction, and to insert the bottom of the steel bars into the concrete, but tying the horizontal or vertical super-strong steel bars takes a lot of time.

At the same time, since they are both embedded in concrete, the subsequent stability is improved.

[0025] Example 2

[0026] Please see Figure 1-5A reinforced concrete slab bottom reinforcement support structure includes, when using the mechanism, firstly, connecting steel plate 4 and connecting steel plate 7 are integrally fixed at both ends of steel horizontal plate 1 and steel horizontal plate 2, respectively, and a snap-lock column 8 is welded and fixed on the connecting steel plate 27, wherein the snap-lock column 8 is divided into two semi-circular parts with a gap in the middle of the two semi-circles, and the diameter of the connection between the snap-lock column 8 and the connecting steel plate 27 is adapted to the inner diameter of the reserved hole 3. When assembling multiple steel horizontal plates 25 and steel horizontal plates 1 vertically, a connecting plate 10 is required. Using the connecting plate 10, the snap-fit ​​post 12 passes through the pre-drilled hole 3 into the connecting steel plate 4 on one side of the steel horizontal plate 25 or steel horizontal plate 1. The pre-drilled hole 11 on the connecting plate 10 engages with the snap-fit ​​post 8 on the connecting steel plate 7 on one side of the steel horizontal plate 1 and steel horizontal plate 25, thus connecting and fixing the vertically assembled multiple steel horizontal plates 11 or multiple steel horizontal plates 25. The connecting steel plate 4 has a pre-drilled hole 3 vertically formed to mate with the snap-fit ​​post 8. A connecting plate 10 is provided on one side of the steel horizontal plate 25, and the connecting plate 10 is a right-angled rectangular plate when viewed from above. A pre-drilled hole 11 is vertically formed on one side of the top of the connecting plate 10, and a snap-fit ​​post 12 is integrally welded to the other side of the top of the connecting plate 10. The dimensions of the second snap-on post 12 and the second reserved hole 11 are adapted to the dimensions of the first reserved hole 3 and the first snap-on post 8, respectively; the top of the first steel horizontal plate 1 and the second steel horizontal plate 5 are jointly provided with a limiting hole 13, and a vertical steel bar 2 is vertically inserted in the limiting hole 13 between the first steel horizontal plate 1 and the second steel horizontal plate 5. The limiting hole 13 limits the vertical steel bar 2, maintains the verticality of the vertical steel bar 2, and the vertical steel bar 2 is located in the concrete. After the steel horizontal plate 25 and the steel horizontal plate 11 are connected, the vertical steel bar 2 can be inserted into the limiting hole 13 first. When the steel horizontal plate 11 and the steel horizontal plate 25 are connected, the connecting steel plate 16 is inserted into the steel horizontal plate 11 through the connecting cavity 17. After the connecting steel plate 16 is inserted into the steel horizontal plate 11, one end of the connecting steel plate 16 is stuck in the connecting groove 9. The connection between the steel horizontal plate 11 and the steel horizontal plate 25 is improved by the action of the connecting steel plate 16 and the connecting groove 9. When multiple steel horizontal plates 11 or multiple steel horizontal plates 25 are connected to each other, the connecting steel plate 4 is aligned and placed on the connecting steel plate 27. Then, the snap-on column 8 is pushed through the pre-reserved hole 3 to pass through the connecting steel plate 4. In this way, multiple steel horizontal plates 11 or multiple steel horizontal plates 25 can be assembled.

[0027] Working principle: In use, firstly, connecting steel plate 4 15 and connecting steel plate 3 14 are inserted into each other through the butt joint hole 6, and connecting steel plate 3 14 and connecting steel plate 4 15 are pressed against the ground to support steel horizontal plate 2 5 and steel horizontal plate 1 1.

When multiple steel horizontal plates 1 and vertical reinforcing bars 2 need to be connected, the reserved holes 3 on the connecting steel plate 4 are assembled onto the snap-on column 8 by extrusion, or the connecting plate 10 is inserted into the connected steel horizontal plates 1 and 2 5. At this time, the reserved holes 2 11 and snap-on columns 2 12 are fixed to the reserved holes 3 and snap-on columns 8 respectively. Subsequently, the vertical reinforcing bars 2, steel horizontal plates 1 and 2 5 are all fixed in the concrete, and the use of the bottom reinforcement support structure of the reinforced concrete slab is finally completed.
