Embodiment 1

[0023] Embodiment 1, as shown in Figures 1 and 2, a special electrical installation project embedded positioning sleeve 1 in this embodiment includes a base 1-3 and a pipe body 1-2 on it, and the pipe body 1-2 is formed with a In the inner cavity suitable for the set of pre-embedded lines, there is a ring of stopper protrusions 1-4 on the inner cavity wall, the base 1-3 is triangular in shape, and each of its three corners has a screw hole 1-3-1 .

[0024] As shown in Fig. 4, the left picture in Fig. 4 is a reference picture of the use state of the present invention, and the right picture is a reference picture of the traditional tool use state. When in use, fix the pre-embedded positioning sleeve 1 of the electrical installation project to the position of the embedded line on the template 4 with screws, and then insert the pre-embedded line tube 2 into the upper inner cavity of the embedded positioning sleeve 1 of the electrical installation project , through the stopper pro...

Embodiment 2

[0026] Embodiment 2, as shown in Figure 3, differs from Embodiment 1 in that: the base 1-3 of this embodiment is two lugs, and the lugs are relatively arranged on the periphery of the pipe body, and there are screws on the lugs Hole 1-3-1. Of course, three lugs can also be provided, and the three lugs are distributed on the periphery of the pipe body at intervals of 120°, or four lugs can also be provided, which will not be repeated here.

Abstract

The invention discloses a pre-embedded locating conduit for electrical installation engineering, comprising a base and a conduit body on the base. An inner cavity matched with the sleeved pre-embedded conduit is arranged in the conduit body. Screw holes are arranged on the base. The prior art has the problems that electrical installation pre-embedding procedure damages the formwork, the verticality of the pre-embedded conduit can not be controlled, and the casting quality of concrete surrounding the pre-embedded conduit is bad. However, the pre-embedded locating conduit for electrical installation engineering has the advantages of solving the problems of the prior art, no damaging the template, effectively controlling the position and the verticality of the pre-embedded conduit, improving the concrete quality. The pre-embedded locating conduit for electrical installation engineering has also the advantages of low cost, and convenient manufacture.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a pre-embedded positioning sleeve for electrical installation engineering. Background technique [0002] In the construction of multi-storey and high-rise buildings, the wires are usually connected from the bottom layer, and then pass through the floor from the bottom layer to be connected to each floor. According to the requirements of the electrical installation specification, all electrical lines should wear sleeves, that is, plastic pipes or steel pipes are pre-embedded during the construction of the main body (usually concrete). The middle of the beam passes through. The conventional method is to open a hole in the bottom formwork of the beam. The hole is slightly larger than the outer diameter of the embedded pipe. The lower end of the embedded pipe passes through the bottom of the bottom form. The middle and upper parts are fixed on the steel b...
