Description

Technical Field

[0001] The utility model relates to the technical field of embedded boxes, in particular to an embedded mechanism for an electrical box. Background Art

[0002] At present, shear wall structures or frame-shear wall structures are mostly adopted in high-rise buildings in China. Generally, electrical wire boxes need to be embedded in advance in shear walls. During the embedding process, it is necessary to ensure that the position of the embedded wire box is accurate. Most importantly, it is necessary to ensure that after the structure is poured, the embedded wire box does not have problems such as excessive deviation or deformation. The traditional method of fixing the embedded box is to directly or indirectly bind or weld the through-rib bottom box to the wall column steel mesh. During actual pouring, the external forces acting on the wall steel mesh are relatively complex. All of the above fixing devices will shift with the movement of the steel mesh, resulting in excessive deviation of the position of the embedded box. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an embedded mechanism for an electrical box.

[0004] The technical solution of the utility model is as follows: An embedded mechanism for an electrical box includes an embedded box and a locking mechanism. The locking mechanism includes a screw rod and a locking nut. A threaded cylinder for cooperating with the screw rod is provided on one side of the embedded box away from the locking mechanism; one end of the screw rod passes through the formwork and the embedded box in sequence and is threadedly connected with the threaded cylinder. A locking nut is provided at the other end of the screw rod, and the locking nut is in contact with the formwork.

[0005] Further, a positioning groove is provided on one side of the embedded box close to the locking mechanism, and a cover is provided in the positioning groove.

[0006] Further, the cover is made of foam plastic, and the cover is adhesively bonded to the bottom surface of the positioning groove by chemical glue.

[0007] Further, arched surfaces are provided on the sides of the embedded box.

[0008] Further, a plurality of uniformly spaced strip-shaped protrusions are provided on the arched surfaces.

[0009] Further, the embedded box is provided with a convex edge, the convex edge is integrated with the embedded box, and one side of the convex edge is in contact with the formwork.

[0010] Further, a backing plate is provided between the locking nut and the formwork, and the end surfaces of the backing plate are in contact with the formwork and the locking nut respectively.

[0011] Further, a plurality of symmetrically distributed reinforcing ribs are provided on one side of the convex edge away from the formwork.

[0012] Further, a polygonal block is provided at the end of the screw rod away from the embedded box, and the polygonal block is integrated with the screw rod.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: When pouring the wall, compared with the wall steel bars, the shape and position of the formwork are relatively stable. The embedded box is fixedly connected to the formwork through the locking mechanism, and the position of the embedded box is not likely to change. The screw passes through the formwork and is threadedly connected to the threaded barrel, quickly confirming the relative position between the embedded box and the formwork. By rotating the locking nut, the screw applies a pulling force to the embedded box, causing the embedded box to fit with the formwork and enhancing the assembly strength between the embedded box and the formwork.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope protected by the present utility model.

[0020] The following will describe the specific embodiments of the present utility model in conjunction with the drawings:

[0021] As Figures 1 to 3As shown in the figure, an embedded mechanism for an electrical box includes an embedded box 1 and a locking mechanism 2. The locking mechanism 2 includes a screw 21 and a locking nut 23. A threaded cylinder 14 for mating with the screw 21 is provided on one side of the embedded box 1 away from the locking mechanism 2. One end of the screw 21 sequentially passes through the formwork and the embedded box 1 and is threadedly connected to the threaded cylinder 14. A locking nut 23 is provided at the other end of the screw 21, and the locking nut 23 is in contact with the formwork. A polygonal block 211 is provided at the end of the screw 21 away from the embedded box 1, and the polygonal block 211 is integrated with the screw 21. The polygonal block 211 facilitates manually or using tools to clamp the screw 21 and apply torque. A backing plate 22 is added between the locking nut 23 and the formwork, and the end faces of the backing plate 22 are respectively in contact with the formwork and the locking nut 23. The backing plate 22 is used to increase the contact area between the locking nut 23 and the formwork, preventing the locking nut 23 from being tightened too much and damaging the surface of the formwork. Through the cooperation of the screw 21 and the threaded cylinder 14, the relative position between the embedded box 1 and the formwork is initially and quickly determined. By rotating the locking nut 23, the screw 21 is subjected to axial tension, driving the embedded box 1 to closely adhere to the formwork, thereby enhancing the bonding strength between the embedded box 1 and the formwork.

[0022] A positioning groove 121 is provided on one side of the embedded box 1 close to the locking mechanism 2, and a cover 11 is provided in the positioning groove 121. The cover 11 is made of foam plastic, and the cover 11 is adhesively bonded to the bottom surface of the positioning groove 121 by chemical glue. The cover 11 closes the open surface of the embedded box 1, preventing concrete from passing through the open surface and entering the interior of the embedded box 1 during the pouring process. After the pouring is completed, when the embedded box 1 needs to be used, the cover 11 can be directly torn off. The cover 11 made of foam plastic has low strength and is easy to remove. The embedded box 1 is provided with a flange 12, and the flange 12 is integrated with the embedded box 1. One side of the flange 12 is in contact with the formwork. A plurality of symmetrically distributed reinforcing ribs 122 are provided on the side of the flange 12 away from the formwork. The flange 12 increases the contact area between the embedded box 1 and the formwork, preventing the locking nut 23 from being too tight and applying too much load to the embedded box 1, resulting in deformation of the embedded box 1. The reinforcing ribs 122 enhance the anti-deformation ability of the flange 12.

[0023] An arched surface 13 is provided on each side of the embedded box 1. During the pouring process, a large amount of concrete forms a certain impact on the side of the embedded box 1, generating a large shear force on the embedded box 1. The arched surface 13 is beneficial to decomposing the impact of the concrete on the embedded box 1, keeping the embedded box 1 stable during the pouring process. A plurality of evenly spaced strip-shaped protrusions 131 are provided on the arched surface 13. The strip-shaped protrusions 131 can enhance the strength of the arched surface 13, and at the same time increase the adhesion area between the embedded box 1 and the concrete, enhancing the bonding strength between the embedded box 1 and the concrete.

[0024] The working principle of the specific embodiment of the utility model is as follows: One end of the screw rod 21 passes through the template and extends into the embedded box 1 and is threadedly connected to the threaded cylinder 14. Rotate the locking nut 23 so that the screw rod 21 is subjected to an axial tensile force, and the screw rod 21 pulls the embedded box 1 to be tightly attached to the template. After pouring is completed, loosen the locking nut 23, and then rotate the screw rod 21 to separate the screw rod 21 from the embedded part, and the template can be removed. At this time, the embedded box 1 is integrated with the concrete wall.
