Description

Pre-buried type electric box internal support tool

Technical Field

The application relates to the technical field of assembly of electric boxes in walls, in particular to an embedded type electric box inner supporting tool.

Background

At present, in the building installation engineering, two installation modes are adopted for the distribution box which is concealed and installed on the wall, wherein the first mode is to reserve a hole first, and install the distribution box after wall construction is completed; another way is to pre-embed the distribution box in advance and then cast a concrete wall. In actual construction, the first mode has the advantages that the distribution box is not required to enter the field in the early stage of construction, the fund pressure in the early stage is reduced, meanwhile, the damage to the electric box caused by concrete pouring (vibration) is reduced, a temporary wooden box mold (for a reserved hole) is required to be manufactured, the wooden box mold is required to be dismounted subsequently, the regular distribution box is required to be fixed firmly after being installed, gaps between the distribution box and the wall are required to be blocked, and labor waste is required.

The second mode has the advantages that the electric box can be constructed synchronously with the wall, can be better and reliably combined with the concrete wall, can be well embedded on the concrete wall, does not need subsequent plugging and fixing, and is widely used at present. However, because the electric box shell belongs to a thin-wall part, the influence of pressure generated in the process of pouring concrete in the construction process on the electric box shell is not considered in the design process, in addition, in the process of vibrating the concrete by using a vibrating rod, permanent deformation damage (the state shown in the attached figure 3 of the specification) is easily generated on the electric box shell by improper operation of an operator, even the electric box shell is worn, and when the deformation damage is serious, the electric box shell can only be scrapped.

Thus, at present, when concrete walls are cast, measures are required to protect the electric box. The traditional solution is to use square timber as an internal support top support in the distribution box to increase the strength and rigidity of the box body. According to the method, square timber cannot be reused after being dismantled, more construction waste is generated, the green construction requirements are not met, meanwhile, the electric boxes with different specifications are required to be made into the matched timber support, and the construction period of the installation of the electric boxes is prolonged.

In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described below with reference to the accompanying drawings and examples.

Referring to fig. 1-5, an embedded type electric box inner support tool is used for fixing binding steel bars and pouring templates before pouring an electric box and a wall body. The inner support tool comprises a base plate assembly which can be attached to each inner wall of the electric box 10, the base plate assembly is attached to each inner wall of the electric box which is fixed in a pre-buried mode, on the basis of attaching, the support tool further comprises a support assembly which is used for fastening and pressing the base plate assembly onto the inner wall of the electric box 10, the support assembly can provide a pressing force for the base plate assembly attached to the inner wall of the electric box, the base plate assembly can be pressed onto each inner wall of the electric box, when the base plate assembly is subjected to external force of concrete pouring of a wall body, an effective supporting and resisting effect on the side wall of the electric box is provided, and the problem that the box body is easy to deform when concrete pouring is achieved is solved.

Because the cushion plate component is assembled in the electric box, the outline dimension of the cushion plate component is smaller than the internal dimension of the electric box, the cushion plate component can not realize complete support on the inner wall of the electric box, and when concrete is poured subsequently, the concrete covering and vibrating effect on the outer side wall of the whole electric box are realized, so that in order to avoid the problem that the cushion plate component is irrecoverably deformed at the position (especially at a plurality of vertex angles in the electric box) where the inner wall of the electric box is not supported in place due to concrete pouring vibration, the cushion plate component also comprises a vertex angle supporting component synchronously supporting the adjacent side walls of the electric box 10, and the vertex angle supporting component and the cushion plate component jointly realize complete internal support on the inner wall and the vertex angle of the electric box, thereby overcoming the deformation problem during concrete pouring and ensuring the installation integrity of the embedded electric box.

Specifically, as shown in fig. 1, the pad assembly includes an inner pad 1 in flat contact with each inner sidewall of the electric box 10. Each inner backing plate 1 is generally smaller than the length of the inner wall of the corresponding attached electric box, so that the inner backing plates 1 can be conveniently embedded. The supporting component is a center support 2 embedded in the electric box and in a frame shape, a detachable adjusting bolt mechanism is arranged between each side edge of the inner backing plate 1 corresponding to the center support 2, and the detachable adjusting bolt mechanism preferably specifically comprises: the space welding is at the nut of the outside edge that center support 2 and every internal bolster 1 all parallel correspond, all wears to be equipped with in every nut with every internal bolster 1 all contact adjusting bolt (the positioning groove of embedding adjusting bolt is all offered to the preferred on every internal bolster 1, not shown in the figure, realizes both embedding spacing), realizes hugging closely the back with internal bolster 1 through rotatory every adjusting bolt, and accessible internal bolster 1 realizes quick internal support effect to the electronic box inner wall.

Preferably, the adjusting bolts inside the central support 2 are further sleeved with locking nuts, and the central support 2 on both sides of each adjusting bolt is additionally provided with the nuts, which are used for increasing the number of the adjusting bolts and improving the stability of the inner support plate 1 when the box body thickness, the wall thickness and the like are required to be reinforced for supporting the inner support plate 1, as shown in fig. 2.

And the detachable adjusting bolt mechanisms are arranged between the vertex angle backing plate 3 and the corresponding position of the center support 2. The vertex angle backing plate 3 is connected with the center support 2 through adjusting bolts and is adjusted, after supporting of each vertex angle of the inner cavity of the electric box is achieved through the vertex angle backing plate 3, the inner backing plate 1 can be assisted to achieve complete supporting of the inner wall of the electric box, the problem that unrecoverable concave deformation occurs to the vertex angle in the electric box due to concrete vibration as shown in fig. 3 is solved, deformation resistance of the electric box during subsequent concrete pouring and vibration is improved, the problem of the electric box cost increased due to deformation of the existing electric box is solved, and meanwhile the inner supporting device can be reused, and the cost and supporting efficiency of the existing wood supporting are reduced.
