Special wire box for prefabricated laminated plates and construction method thereof

Abstract

The invention provides a special wire box for prefabricated laminated plates. The special wire box comprises a bottom box and a top box, the bottom box is composed of a box wall in a through pipe shape and two reinforcing steel bar penetration connecting blocks fixedly connected to the box wall, and the reinforcing steel bar penetration connecting blocks are provided with reinforcing steel bar holes; the upper part of the bottom box is provided with an internal thread, and the lower part of the bottom box is provided with a screw fixing groove; and the top box is composed of a top plate and abox body, the top plate and the box body are provided with pipe penetrating holes, and the lower part of the box body is provided with an external thread. A construction method of the special wire boxfor the prefabricated laminated plates is also provided; reinforcing steel bars penetrate into the reinforcing steel bar holes in the bottom box, the bottom box is embedded in a stacking plate when the stacking plate is prefabricated, the bottom box screw fixing groove side is flush with the lower surface of the stacking plate, the thread side is exposed out of the upper surface of the stacking plate, a floor plate is installed on site, and wire box locking nuts are selected to be installed on one or more pipe penetrating holes in the top box according to the wire tube design; and finally thetop box is screwed into the bottom box. By means of the method, wire box pre-embedding and wire box installation are split, damage to the wire tube ends before installation is avoided, and great convenience is brought to subsequent construction.

Description

technical field [0001] The invention belongs to the technical field of prefabricated laminated slabs, and in particular relates to a special line box for prefabricated laminated slabs and a construction method thereof. Background technique [0002] In building construction, the roof light box is an indispensable and important part, which ensures the normal use of roof lighting equipment, while the wire box used in the construction process of prefabricated laminated panels in the prior art is a finished PVC octagonal box, and its height Can not meet the construction requirements. [0003] 86 series PVC octagonal box is generally used for the junction box of lamps and lanterns. This kind of junction box is divided into 86h70 and 86h50 series, that is, the height of the junction box is 70mm and 50mm. This makes part or all of the pipe outlet at the junction box immersed in the concrete. In the process of making the laminated board, it is necessary to use a curved wire pipe in ...

AI Technical Summary

Problems solved by technology

[0006] This structure effectively avoids the problem of wire pipe bending when the wire box is pre-embedded in the prefabricated production process of the laminated board, and avoids damage to the wire box during construction and hoisting, thereby improving work efficiency and saving engineering costs
