[0021] In order to make the technical means, innovative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below.

[0022] The embodiments described herein are specific specific embodiments of the utility model, used to explain the concept of the utility model, and are explanatory and exemplary, and should not be interpreted as limiting the embodiments and the scope of the utility model. In addition to the embodiments described herein, those skilled in the art can also use other obvious technical solutions based on the disclosure of the claims and the description of the application, including any obvious replacement and modification of the embodiments described herein.

[0023] Example 1

[0024] An adjustable variable cross-section horizontal ladder reinforcement, such as Figures 1-5 As shown, the device includes two parallel connecting rods 1 and connecting rods 2 for connecting the two connecting rods 1. U-shaped vertical rib limiting grooves 3 are evenly spaced on the opposite sides of the two connecting rods 1. Several connecting rods 2 are spaced apart and connected to the connecting rods 2 on both sides. The connecting rods 2 are connected to the two connecting rods 1 through a fixing assembly 4. The fixing assembly 4 includes a limiting ring 41 welded and fixed on the connecting rod 1 and nuts 42 threaded on the connecting rod 1 and on both sides of the limiting ring 41. The U-shaped vertical rib limiting groove 3 is formed by welding two steel bar segments onto the connecting rod 1. The U-shaped vertical rib limiting groove 3 includes a U-shaped snap-fit ​​part 31 and an adjustable connecting part 32. The adjustable connecting part 32 is fixed at different positions on the connecting rod 1 to make the spacing between adjacent U-shaped vertical rib limiting grooves 3 adjustable. The limiting ring 41 is formed by cutting steel pipe. Both the connecting rod 1 and the connecting rod 2 are made of steel bars. The adjustable connecting part 32 can also be made of small pipe clamps.

[0025] More specifically, this application eliminates the conventional ladder reinforcement section control bars. Instead, galvanized pipes (limiting rings) of the same width and diameter (16mm) are vertically welded onto the horizontal control ladder reinforcement as adjustable variable cross-section fixing points. These fixing points are set bidirectionally along the ladder reinforcement length at intervals not exceeding 500mm. Depending on the different wall cross-section requirements, a 12mm screw rod passes through the 16mm galvanized pipe control point for adjustment. The galvanized pipe fixing point is locked on both sides by two hexagonal nuts to meet the positioning requirements of vertical reinforcement bars in various walls and construction technical quality standards.

[0026] Example 2

[0027] Based on Example 1, such as Figure 4 As shown, the connecting rod 1 is redesigned as a strip-shaped plate structure with a strip-shaped through hole in the middle. The adjustable connecting part 32 is a bolt assembly that is inserted and fixed into the strip-shaped through hole, as shown. Figure 5 As shown, the bolt assembly includes a screw and a nut, with the screw inserted into a strip-shaped through hole and connected by the nut.

[0028] Example 3

[0029] Based on Embodiment 1, the fixing component 4 is modified to be directly rotatable via the connecting rod, including a nut welded and fixed to the connecting rod 1. The connecting rod 2 is provided with a handle. By rotating the connecting rod 2 forward or backward, the relative or opposite movement of the nuts on both sides can be achieved, thereby adjusting the spacing of the connecting rod 1. That is, the thread directions of the nuts on both sides are opposite. In specific use, the variable cross-section horizontal ladder reinforcement is installed firmly in the wall vertical reinforcement 500mm above the floor surface before the floor slab concrete is poured. It is fixed with binding wire, and the spacing should not be greater than 500mm.
