Description

Technical Field

[0001] The utility model belongs to the field of engineering construction, in particular to a pre-embedded non-welding fixing device for a shear wall distribution box. Background Art

[0002] As the process of urbanization continues to deepen, the number of building construction projects has increased, and people's requirements for construction quality have also been continuously improving. Among them, the installation of distribution boxes in the electrical profession in building construction projects has received particular attention from all parties.

[0003] The traditional installation method of shear wall distribution box is to make a wooden frame reserved opening according to the size of the distribution box before pouring the main concrete. After the concrete formwork is removed, the reserved wooden frame is removed, and then the distribution box body is installed and the surrounding openings are repaired. However, due to the instability of the wooden frame and the poor effect of later repairing the openings, this method has basically been eliminated. At present, most shear wall distribution boxes use a one-time embedded installation technology. First, the distribution box body that meets the requirements of the drawings is customized, and then the wire pipe materials with specifications and quantities suitable for this project are configured on the distribution box body. Finally, fixed measures are set around the box body in combination with the size of the distribution box to ensure the embedded effect. However, the current fixing measures often have problems such as poor stability, resulting in unstable installation, or welding fixation, resulting in welding penetration of the distribution box body, making it difficult to ensure the embedded quality. Utility Model Content

[0004] In view of this, the utility model aims to propose a shear wall distribution box pre-embedded non-welding fixing device, which does not need to be formed into a whole by welding, and is all bolted. While ensuring the overall stability of the distribution box structure, problems such as welding through the box or paint peeling will not occur when the distribution box is welded and reinforced with other materials.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A pre-embedded non-welding fixing device for a shear wall distribution box comprises an upper limit mechanism and a lower limit mechanism which are arranged relatively, and a left limit mechanism and a right limit mechanism which are arranged relatively. The upper limit mechanism, the lower limit mechanism and the left limit mechanism, the right limit mechanism cooperate with each other to fix the distribution box.

[0007] Furthermore, the upper limit mechanism and the lower limit mechanism have the same structure, including a No. 1 transverse circular tube, a No. 2 transverse circular tube, and a riding clamp. The No. 1 transverse circular tube and the No. 2 transverse circular tube are arranged in parallel, and the No. 1 transverse circular tube and the No. 2 transverse circular tube are fixed to the upper surface and the lower surface of the distribution box by the riding clamp.

[0008] Furthermore, the length of the No. 1 horizontal circular tube is consistent with the length of the hole reinforcement rib.

[0009] Furthermore, the left limiting mechanism and the right limiting mechanism have the same structure, including a No. 1 vertical circular tube, a No. 2 vertical circular tube and a buckle. The No. 1 vertical circular tube is connected to the No. 1 horizontal circular tube and the No. 2 horizontal circular tube through the buckle and is arranged on one side of the distribution box. The No. 2 vertical circular tube is connected to the No. 1 horizontal circular tube and the No. 2 horizontal circular tube through the buckle and is arranged on the other side of the distribution box.

[0010] Furthermore, the buckle is a double U-shaped cross clamp, and the bent plate is connected to the double U-shaped cross clamp through a nut to achieve fixation between the No. 1 vertical circular tube and the No. 1 horizontal circular tube and the No. 2 horizontal circular tube.

[0011] Furthermore, the No. 1 vertical circular tube and the No. 2 vertical circular tube have the same structure, and the thickness of the No. 1 vertical circular tube is the same as the thickness of the shear wall.

[0012] Compared with the prior art, the pre-embedded non-welding fixing device for the shear wall distribution box described in the utility model has the following advantages:

[0013] The utility model discloses a shear wall distribution box pre-embedded non-welding fixing device. By setting a limit device around the distribution box, the distribution box is fixed on the No. 1 horizontal round tube and the No. 2 horizontal round tube by using a riding clamp and screws to achieve the upper and lower limit of the distribution box; and the No. 1 vertical round tube, the No. 2 vertical round tube and the No. 1 horizontal round tube, the No. 2 horizontal round tube are fastened together by using a double U-shaped cross clamp to achieve the left and right and front and back limit of the distribution box, wherein the length of the No. 1 and No. 2 vertical round tubes is the same as the thickness of the shear wall to ensure that the distribution box does not sag during the concrete pouring process. In addition, the devices do not need to be welded to form a whole, and are all bolted. While ensuring the overall stability of the distribution box structure, the box body will not be welded through or the paint will not fall off when the distribution box is welded and reinforced with other materials. In addition, the manufacturing materials are simple, the manufacturing method is easy, and it has the advantages of simple structure, low cost and easy promotion and application.

[0023] A pre-buried non-welding fixing device for a shear wall distribution box, such as Figure 1 Figure 2 As shown, it includes an upper limit mechanism and a lower limit mechanism that are relatively arranged, and a left limit mechanism and a right limit mechanism that are relatively arranged. The upper and lower limit mechanisms and the left and right limit mechanisms cooperate with each other to fix the distribution box, thereby realizing the upper, lower, left and right limit of the distribution box.

[0024] Preferably, the upper limit mechanism and the lower limit mechanism have the same structure, including a No. 1 transverse circular tube 2, a No. 2 transverse circular tube 3, and a riding clamp 4. The No. 1 transverse circular tube 2 and the No. 2 transverse circular tube 3 are arranged in parallel, and the No. 1 transverse circular tube 2 and the No. 2 transverse circular tube 3 are fixed to the upper surface and the lower surface of the distribution box by the riding clamp 4.

[0025] Preferably, the length of the No. 1 transverse circular tube 2 is consistent with the length of the opening reinforcement, so that the No. 1 transverse circular tube 2 can be tied to the shear wall reinforcement during installation; the length of the No. 2 transverse circular tube 3 can meet the required length of the clip 8, that is, it is enough to install the clip 8.

[0026] Preferably, the left limiting mechanism and the right limiting mechanism have the same structure, including a No. 1 vertical circular tube 6, a No. 2 vertical circular tube 7 and a buckle 8. The No. 1 vertical circular tube 6 is connected to the No. 1 horizontal circular tube 2 and the No. 2 horizontal circular tube 3 through the buckle 8 and is arranged on one side of the distribution box. The No. 2 vertical circular tube 7 is connected to the No. 1 horizontal circular tube 2 and the No. 2 horizontal circular tube 3 through the buckle 8 and is arranged on the other side of the distribution box.

[0027] Preferably, the buckle 8 is a double U-shaped cross clamp 9, and the bent plate 10 is connected to the double U-shaped cross clamp 9 through a nut 11 to achieve fixation between the No. 1 vertical circular tube 6 and the No. 1 horizontal circular tube 2 and the No. 2 horizontal circular tube 3.

[0028] Preferably, the No. 1 vertical circular tube 6 and the No. 2 vertical circular tube 7 have the same structure, and the thickness of the No. 1 vertical circular tube 6 is the same as the thickness of the shear wall to ensure that the distribution box does not shift or sag during the concrete pouring process, and to ensure that the wall protrusion rate of the distribution box meets the requirements.

[0029] During production, first, the distribution box body is equipped with pipes. In this embodiment, the distribution box body 1 includes a distribution box body and pipes. The distribution box body includes an upper side, a lower side, a left side, a right side and a rear side. The upper side of the distribution box body is equipped with 9 PVC wire pipes, and the lower side is equipped with 1 PVC wire pipe. The material, specification and quantity of the wire pipes can be selected according to the actual situation of the project;

[0030] Second, the upper and lower limit mechanisms are connected to the distribution box body 1. In this embodiment, Figure 1 As shown, the upper and lower limit devices include a No. 1 transverse circular tube 2, a No. 2 transverse circular tube 3, a riding clamp 4 and a screw 5. The circular tube can be a lightweight round steel tube such as a JDG tube; the length of the No. 1 transverse circular tube 2 is consistent with the length of the opening reinforcement, and the No. 1 transverse circular tube 2 is tied to the shear wall reinforcement during installation; the length of the No. 2 transverse circular tube 3 only needs to meet the required length of the double U-shaped cross buckle 8; after the No. 1 transverse circular tube 2 and the No. 2 transverse circular tube 3 are prepared, the riding clamp 4 and the screw 5 are used to fix the distribution box body 1 on the No. 1 transverse circular tube 2 and the No. 2 transverse circular tube 3 to fix the distribution box body 1.

[0031] Third, the left and right limit mechanisms are connected to the upper and lower limit devices. Figure 1 and Figure 2 As shown, first place the double U-shaped cross clamp 9 in the double U-shaped cross buckle 8 on each of the No. 1 horizontal round tube 2 and the No. 2 horizontal round tube 3, then insert the No. 1 vertical round tube 6 into the double U-shaped cross clamp 9, then buckle the bent plate 10 under the left vertical round tube, and then tighten and reinforce the connection between the No. 1 horizontal round tube 2, the No. 2 horizontal round tube 3 and the No. 1 vertical round tube 6 with the nut 11, and then complete the connection between the No. 1 horizontal round tube 2, the No. 2 horizontal round tube 3 and the No. 2 vertical round tube 7 in the same way. The length of the No. 1 vertical round tube 6 and the No. 2 vertical round tube 7 is the same as the thickness of the shear wall, and they are flush with the front side of the distribution box body 1 during installation to ensure that the distribution box does not shift or sink during the concrete pouring process, and to ensure that the wall rate of the distribution box meets the requirements.

[0032] During installation, based on the size of the distribution box, cut off the steel bars of the distribution box body 1 at the shear wall installation position. The cutting range should ensure that the distribution box can be placed horizontally and vertically. Then tie the No. 1 horizontal round tube 2 to the shear wall steel bars with wire. To further ensure a firm installation, the left and right vertical round tubes can also be tied to the shear wall steel bars. Then use PVC pipes as support rods inside the distribution box body 1 or use other methods to support the inner wall of the distribution box body 1 to ensure that the side walls of the distribution box body 1 are not squeezed when pouring concrete.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
