[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Figure 1 This is a schematic diagram of the structure of a reinforcement connection tool for vertical cast-in-place concrete side formwork according to the present invention; Figure 2 This is an exploded view of the utility model's reinforcement and connection tool for vertical cast-in-place concrete side formwork; Figure 3 This is a schematic cross-sectional view of the reinforcement connection tool of the present invention.
[0021] See Figure 1 、 Figure 2 and Figure 3 The utility model provides a reinforcement connection tool for vertical cast-in-place concrete side formwork, which includes, from left to right: a nut 4, a reinforcement connector 1, a tension screw 2, a mountain clip 3, and a nut 4. The reinforcement connector 1 and the nut 4 are arranged at one end of the tension screw 2, and the mountain clip 3 and the nut 4 are arranged at the other end of the tension screw 2. The reinforcement connector 1 is formed with a tension screw hole 5 and a steel pipe connection groove 6. The reinforcement connector 1 is locked and connected to the tension screw 2 through the tension screw hole 5, the nut 4, and the tension screw 2.
[0022] During the formwork installation process, square timbers 9 are used vertically, and two layers of steel pipes 7 are used horizontally to secure the formwork using front-to-back and left-to-right double-sided tension screws, mountain clamps, and nuts. The corner side formwork is secured using the reinforcement connection tool of the present invention. Specifically, the vertical cast-in-situ concrete side formwork includes multiple vertically arranged square timbers 9, which are secured by a first and second vertically arranged double-layer steel pipe group; the mountain clamps 3 are clamped to the two steel pipes 7 in the first double-layer steel pipe group, and the steel pipe connecting grooves 6 are clamped to the adjacent steel pipe 7 in the second double-layer steel pipe group, as shown in FIG. Figure 4 and Figure 5 shown.
[0023] Please refer to Figure 3 and Figure 5 , the tension screw 2 passes through the tension screw channel 5 of the reinforcement connector 1; in addition, the steel pipe connection groove 6 of the reinforcement connector 1 is clamped on the outside of the mountain-shaped clamp of the upper steel pipe, and the mountain-shaped clamp 3 that fixes the steel pipe 7 acts as a limiter for the reinforcement connector 1. The reinforcement connector 1 and the tension screw 2 are fixed with nuts 4. Figure 4 As shown, a chevron clamp 3 on the side of the formwork passes through the tension screw 2 and is clamped to the upper two layers of steel pipes. The upper two layers of steel pipes act as limiters for the chevron clamp 3. The chevron clamp 3 is tightened and fixed with nuts 4 and screws. This reinforced connection tool for vertical cast-in-place concrete side formwork is installed at the four corners of the formwork, forming an integrated formwork system. This ensures stability and tightness at the side formwork corners, preventing formwork explosion during concrete pouring.
[0024] Preferably, there are multiple reinforcement connection tools, and the number of the tension screws 2 is multiple, arranged at equal intervals along the first double-layer steel pipe group and the second double-layer steel pipe group. The gap between the two steel pipes 7 in the first double-layer steel pipe group and the second double-layer steel pipe group is slightly larger than the diameter of the tension screw 2. The steel pipe connection groove 6 is semi-circular, and the diameter of the steel pipe connection groove 6 is consistent with the diameter of the steel pipe 7; the groove wall thickness of the steel pipe connection groove 6 is consistent with the diameter of the tension screw 2, ensuring sufficient strength and providing sufficient space for anchoring the tension screw, nut and steel pipe.
[0025] The utility model provides a reinforcement connection tool for vertical cast-in-place concrete side formwork, which is located on the side of the side formwork. One end of the reinforcement connection piece uses a steel pipe mountain-shaped clamp that is fixedly connected to the formwork as a limiter, with good clamping effect, easy installation and good stability. The tool and the steel pipe are fixed using the mountain-shaped clamp; using the steel pipe as a limiter, the tool connection limit is more secure.
[0026] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
