AI Technical Summary
In the shear wall structure, the embedded wire box is installed inaccurately due to inaccurate positioning of steel bars and vibration of concrete pouring, which is prone to problems such as skew, distortion and concrete pollution. The traditional secondary fixing method will cause the formwork to be damaged and the iron nails to be left on the wire box, causing quality hazards.
The shear wall embedded wire box template reinforcement tool including horizontal struts, cross support and limiting devices is used to securely position the wire box between the two sides through horizontal struts and cross support, and the limiting device is used to ensure the accuracy and stability of positioning.
The stable and fixed position of the wire box is achieved, which avoids the installation inaccurate problems caused by steel bar deviation or concrete vibration, ensures good molding effect, and does not affect the integrity of the formwork when dismantling the mold, and improves the construction quality.

Technical Field
[0001] The utility model discloses a shear wall pre-buried wire box template reinforcement tool, belonging to the technical field of pre-buried wire box reinforcement tools. Background Art
[0002] At present, most high-rise residential buildings in my country use shear wall structures or frame shear wall structures, and wire boxes need to be pre-buried on the shear wall in advance. When pre-buried wire boxes, they are mostly fixed by threading wire boxes, or they are fixed on the shear wall steel bars for pre-buried. However, after the shear wall steel bars are tied, when the formwork is closed, due to inaccurate steel bar positioning or vibration during concrete pouring and vibrating, the wire box is difficult to fit the formwork, and the position will also shift with the displacement of the steel bars, causing the cast pre-buried wire box to be skewed, twisted, and contaminated with concrete. The traditional way to solve this kind of problem is to use single-side mold closing and positioning, and then use iron nails for secondary fixing. The molding effect is very good, but the wire box is often damaged when the formwork is demolded, and the iron nails left on the wire box cause quality risks such as rust. How to ensure that the installation positioning is firm, the formwork is easy to remove, and the materials are easy to construct are the most urgent issues that need to be considered and solved for the current concrete pre-buried wire boxes.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, a shear wall pre-buried wire box template reinforcement tool comprises: a horizontal support rod 1, a cross support 2 and a limit device 3 for limiting the position of a first slip ring 11 on the horizontal support rod 1, the middle parts of the four horizontal support rods 1 are all slidably sleeved with a first slip ring 11, the four ends of the cross support 2 are respectively fixedly connected with a first slip ring 11, the cross support 2 comprises two oblique support rods 21, the middle parts of the two oblique support rods 21 are rotatably sleeved on a rotating shaft 22, the length of the horizontal support rod 1 is adapted to the thickness of the shear wall, the length of the horizontal support rod 1 = the thickness of the shear wall - the edge thickness of the wire box 4, and the distance between the first slip ring 11 and the front end of the horizontal support rod 1 is adapted to the depth of the wire box 4;
[0026] The front ends of the horizontal support rods 1 are inserted into the outer edges of the wire box 4, and the rear ends are provided with right-angled edges 12, which can be stably supported on the template.
[0027] The limiting device 3 includes a horizontal limiting rod 31, a first oblique limiting rod 32, a second oblique limiting rod 33, a third oblique limiting rod 34 and a fourth oblique limiting rod 35. The horizontal limiting rod 31 is located at the rear of the cross support 2, and two second sliding rings 36 are slidably mounted thereon. One end of the first oblique limiting rod 32 and the second oblique limiting rod 33 are hinged together and fixed to one second sliding ring 36. The other ends of the first oblique limiting rod 32 and the second oblique limiting rod 33 are respectively hinged to two adjacent first sliding rings 11. One end of the third oblique limiting rod 34 and the fourth oblique limiting rod 35 are hinged together and fixed to another second sliding ring 36. The other ends of the third oblique limiting rod 34 and the fourth oblique limiting rod 35 are respectively hinged to the remaining two first sliding rings 11.
[0028] The horizontal limit rod 31 is flush with the rear end of the horizontal support rod 1, and the length of the horizontal limit rod 31 is adapted to the width of the wire box 4. When the cross support 2 is opened to accommodate the wire box 4, the two second slip rings 36 slide to the two ends of the horizontal limit rod 31, and the horizontal limit rod 31 is flush with the rear end of the horizontal support rod 1.
[0029] The front end of the horizontal support rod 1 is a flat head with a thickness adapted to the height of the gap at the outer edge of the wire box 4 .
[0030] The length of the right-angled edge 12 is 5 mm.
[0031] The horizontal support rod 1 is a round steel rod with a diameter of 5-8 mm.
[0032] The first slip ring 11 is a steel ring with a cross-sectional diameter of 3-5 mm.
[0033] The two diagonal braces 21 are steel bars with a width of 5-8 mm and a thickness of 2-3 mm.

[0036] When in use, the cross support 2 is opened, driving the four horizontal support rods 2 to open as well. At the same time, the four oblique limit rods also move with it. The two second sliding rings 36 slide to both ends on the horizontal limit rods 31. The four horizontal support rods 1 and the cross support 2 form a square frame. The front end of the horizontal support rod 1 is inserted into or pressed against the outer edge of the wire box 4. The wire box 4 is located in this square frame.

After mold closing, the horizontal support 1 is pressed between the templates on both sides, the horizontal limit rod 31 is pressed against one side of the template, and the wire box 4 is clamped between the four horizontal support rods 1. Several oblique limit rods press the cross support 2 against the back of the wire box 4, and the wire box 4 is firmly locked between the templates on both sides.
