Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a deformation prevention support device for embedded distribution boxes. Background Technique

[0002] With the improvement of the quality requirement standard for electrical embedding in the structural stage, the quality requirement for electrical box embedding in the primary structural wall is improved to achieve better appearance effects and avoid the occurrence of hollowing and box body indentation and deformation. Currently, there are two common methods for installing electrical distribution boxes in the structural embedding stage. One is to reserve holes in the structural wall, and after installing the distribution box later, bricks or grouting materials are used for blocking. This method is relatively complex, not conducive to one-piece forming, the forming effect is not ideal, and the economic benefit is poor. The other is that during the structural construction stage, the distribution box body is embedded together with the structural wall. This construction method is convenient for one-piece forming, the structural surface effect is good, the process is simple, and the economic benefit is high. However, there is a risk that the box body is deformed by the vibration rod or extruded by the concrete, resulting in the situation of secondary chiseling and replacing the distribution box shell and re-piping later.

[0003] The above methods cannot meet the quality requirements for electrical box embedding, especially in the case where there are embedding requirements for electrical boxes. Therefore, box support devices disclosed in CN114215350A and CN215368734U appear to avoid the box body being extruded and deformed. However, the above support can only support the side, and there is no support for the back of the box body. Moreover, since the area of the back of the box body is larger, it is more likely to be extruded and deformed. However, since no support points can be provided on the front side of the box body, the prior art cannot solve the problem of back support. The utility model provides a deformation prevention support device for embedded distribution boxes to solve the above problems. Summary of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] In the description of the present utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0027] Such as Figure 1 、 2As shown in the figure, a concealed distribution box anti-deformation support device includes a side support 1 and a back support 2, and both the side support 1 and the back support 2 are arranged inside the box. In the present utility model, the side support 1 and the back support 2 are respectively used to support the side and the back of the box body. Since the sides of the box body are relatively symmetrical, the symmetrically arranged side supports 1 can be used to support the sides, and the supporting effect is achieved through the acting forces in opposite directions. Since the box door on the front side of the box body is not subjected to the pressure of concrete during the pouring process, if the side support 1 is used to support the back of the box body, the pressure transmitted by the back of the box body under the concrete pressure will cause the box door to deform. Therefore, the supporting method of the side support 1 cannot be adopted, and there are no vertical edges on both sides of the front box door of some distribution boxes, so the front side edges cannot be used as support points for support. The present utility model uses the restoring elastic force of the bow-shaped plate bending as the supporting reaction force to support the back of the box body, realizing the unilateral support of the back of the box body, and using the vertical edges on the back side of the box body for support. The restoring elastic force of the bow-shaped plate will not act on the back surface and will not cause the deformation of the box body structure, having no influence on the box body structure, and well solving the problem of supporting the back of the box body.

[0028] As Figure 1 , 2 shown, in a specific embodiment of the present utility model, two groups of side supports 1 and one group of back supports are adopted. The two groups of side supports 1 respectively support the upper and lower sides and the left and right sides of the box body. The two groups of side supports 1 are arranged perpendicular to each other and are connected by a rotating shaft, so that the vertically arranged side support 1 is used for installing the horizontally arranged side support 1, facilitating the installation and setting of the horizontally arranged side support 1 and making it more convenient to take and place; one group of back supports 2 is arranged on the back of the box body. The back support 2 uses the restoring elastic force of the bow-shaped plate 23 to be stuck on the back of the box body, and when the back of the box body bears pressure, the restoring elastic force that drives the bow-shaped plate 23 to deform is used as a reaction force to jack up the second support rod 22 and the second support plate 21, avoiding the deformation of the back of the box body, and thus realizing the support of the back of the box body.

[0029] As Figure 3 , 4 As shown in FIGS. 4 and 5, the side supports 1 are arranged in groups and include a first support plate 11, a first support rod 12 and a mounting sleeve 13. The mounting sleeves 13 of adjacent side supports 1 are movably connected to each other through a rotating shaft. The first support rods 12 are arranged in pairs in the mounting sleeve 13, and the two first support rods 12 are symmetrically connected to both ends of the mounting sleeve 13. The first support plate 11 is fixedly arranged at the outer end of the first support rod 12 and fits on the inner surface of the box body side plate. Each group of side supports 1 includes two first support rods 12 and one mounting sleeve 13. The inner ends of the two first support rods 12 are threadedly connected to the ends of the mounting sleeve 13, and the telescopic length is adjusted by rotation.

[0030] AsFigure 6 , 7 As shown in Figure 8, the back support 2 includes a second support plate 21, a second support rod 22 and a bow plate 23, both ends of the bow plate 23 are clamped at the vertical edges on the rear side of the box body, the bow plate 23 is bent into a bow shape, the front end of the second support rod 22 is arranged on the bow plate 23, the second support plate 21 is arranged at the rear end of the second support rod 22, and the second support plate 21 is in contact with the inner surface of the back plate of the box body.

[0031] The back support 2 realizes support by the following principle: when the back support 2 is installed, the bow strip 232 is bent and stuck on the clamping strip 231. The clamping strip 231 has a restoring elastic force to restore its original state at this time. The restoring elastic force is at the end of the bow strip 232 and is directed outward in an arc shape. After the restoring elastic force acts on the clamping strip 231, the clamping strips 231 on the left and right sides have a tendency to move outward after being stressed. At the same time, the clamping strip 231 is stuck on the vertical edge of the box and cannot move, and then stably stuck on the vertical edge of the box. The stable fixation of the bow plate 23 is achieved through the above principle; and after the bow plate 23 is installed, the restoring elastic force is mainly at the end of the bow strip 232 and acts on the clamping strip 231. The middle part of the bow strip 232 does not have a backward restoring elastic force, so the pressure will not be transmitted to the back of the box through the second support rod 22 and the second support plate 21, so the back of the box will not have a tendency to deform outward; After the concrete is filled, the back side of the box body is under pressure and tends to deform inward, squeezing the second support plate 21. After the second support plate 21 is subjected to force, the pressure is transmitted to the middle part of the bow strip 232 through the second support rod 22, so that the bow plate 23 has a tendency to bend inward and move forward. Since the end of the bow strip 232 is stuck on the clamping strip 231, the pressure generated by the outward movement trend of the two clamping strips 231 produces friction with the box body, so that the bow plate 23 will not move outward, and since the bow strip 232 selected according to the construction situation itself has sufficient restoring elastic force, the pressure transmitted by the second support rod 22 cannot make the bow strip 232 bend inward, and the pressure is offset by the elastic force of the deformation of the bow strip 232, so the bow strip 232 will not bend inward either. Through the above principle, the bow plate 23 provides sufficient supporting force to the back side of the box body, eliminates the tendency of the back side of the box body to deform inward, and realizes support for the back side of the box.

[0032] like Figure 6 , 7 As shown in FIG. 8 , further, the bow plate 23 includes a clamping strip 231, a bow plate strip 232 and a positioning tube 233, the clamping strip 231 is arranged at the vertical edge of the rear side of the box body, the end of the bow plate strip 232 is arranged on the clamping strip 231, the positioning tube 233 is arranged on the inner side of the bow plate strip 232, and the front end of the second support rod 22 is arranged in the positioning tube 233.

[0033] like Figure 5As shown, further, a rotation hole is provided in the middle of the mounting sleeve 13, and a rotating shaft is provided in the rotation hole. The mounting sleeves 13 of adjacent side supports 1 are connected by the rotating shaft.

[0034] Further, the clamping strip 231 is L-shaped, and a retaining piece is provided on its inner side. The retaining piece and the side plate of the clamping strip 231 form a V-shaped groove, and the end of the bow-shaped strip 232 is clamped in the V-shaped groove.

[0035] Preferably, threads are provided on both the mounting sleeve 13 and the first support rod 12, and the mounting sleeve 13 and the first support rod 12 are connected by threads.

[0036] Preferably, the first support plate 11, the second support plate 21, and the bow-shaped strip 232 are 10-mm steel plates, the first support rod 12 is a round steel bar with a diameter of 40 mm and is externally threaded, the second support rod 22 is a round steel bar with a diameter of 40 mm, the clamping strip 231 is an angle steel, and the positioning cylinder 233 and the mounting sleeve 13 are DN40 steel pipes.

[0037] When the present utility model is installed, the back support 2 is installed first. First, the combined component of the second support plate 21 and the second support rod 22 is placed in the box body, and the second support plate 21 is attached to the back surface of the box body. Then, the two clamping strips 231 are placed at the vertical edges on the rear side of the box body. At this time, the above components are all located on the bottom surface of the box body. The operator bends the bow-shaped strip 232 and keeps it in the bent state and places it in the box body. The positioning cylinder 233 on the bow-shaped strip 232 is sleeved on the outer end of the second support rod 22, and then the end of the bow-shaped strip 232 is clamped into the two clamping strips 231. The bow-shaped strip 232 is released, and then the assembled back support 2 is pushed upward as a whole along the back surface of the box body until it reaches the middle of the back surface of the box body, and is clamped on the back surface of the box body by the restoring elastic force of the bow-shaped strip 232 and provides support for the back surface of the box body. After the back support 2 is installed, the side support 1 is assembled outside the box body. After assembly, the telescopic lengths of the first support rod 12 and the mounting sleeve 13 are adjusted to be less than the length and width of the box body. The assembled side support 1 is placed in the box body, and then the telescopic lengths of the first support rod 12 and the mounting sleeve 13 are adjusted in sequence to match the length and width of the box body, thereby realizing the support for the side surface of the box body.
