[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] Conversely, this utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model as defined in the claims. Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0019] Please see Figure 1-4 A type of stirrup for improving the construction quality of basement floor concrete structure includes a horizontal steel bar 1, with support leg assemblies 2 installed on both sides of the horizontal steel bar 1, and two height adjustment rods 3 arranged on the horizontal steel bar 1 between the two support leg assemblies 2.

[0020] Specifically, both sides of the horizontal reinforcing bar 1 are provided with support leg assembly sections. The diameter of the support leg assembly section is smaller than the diameter of the main body of the horizontal reinforcing bar 1. It includes a threaded section 101 at the front end and an installation section 102 at the rear end. The installation section 102 and the main body of the horizontal reinforcing bar 1 form a transversely limiting annular sidewall. The bottom of the installation section 102 is cut off to form a limiting surface 103. Two bases are welded on the horizontal reinforcing bar 1.

[0021] Specifically, the height adjustment rod 3 is a screw structure, which is threadedly installed on the corresponding base. The upper end is provided with an upper steel bar support plate 301, the bottom is provided with a base plate 302 for contacting the ground, and the middle position is threadedly installed with a lower steel bar support plate 303.

[0022] Specifically, the support leg assembly 2 includes a first leg 4 and a second leg 5. Each leg has a collar 7 at the top and a cutting edge at the bottom. The collar 7 is fitted onto the installation section 102, and a limiting steel bar 8 is welded and fixed to its inner wall. A steel wire rope 9 is connected between the two legs, and the legs have a structure that facilitates the binding and fixing of the steel wire rope.

[0023] The construction process using the stirrup reinforcement of this utility model is as follows:

[0024] S1. Initially, the two support legs are folded, and the trestles are placed in the designated position. At this time, the base plate 302 on the height adjustment rod 3 is in contact with the ground.

[0025] S2. Manually rotate to open the two outriggers, rotate the height adjustment rod 3 so that the two outriggers are in contact with the ground and the two outriggers are spread out into a figure-eight shape. At this time, the limiting steel bar 8 is in contact with the limiting surface 103. The entire structure of the stirrup is supported by the outriggers. The steel wire rope 9 is straightened and connected to the two outriggers to serve as an auxiliary fixing structure.

[0026] S3. Continue to rotate the height adjustment rod 3 to the position where the upper rebar is placed, and rotate the lower rebar support plate 303 to the position where the lower rebar is placed. Place the upper and lower rebars that need to be tied onto the upper rebar support plate 301 and the lower rebar support plate 303 to tie the rebars.

[0027] This structure can dynamically adjust the placement of the reinforcing bars according to the actual construction conditions, ensuring the overall flatness of the upper and lower reinforcing bars, improving the construction quality of subsequent pouring construction, and thus improving the overall construction quality; the structure is easy to adjust, can be folded and placed, and is convenient to transport and store.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
