Problems solved by technology
In the existing technology, after investigation, it was found that the existing pre-embedded pipes mainly have defects during use: the formwork is easy to be damaged, and the formwork will be repaired after the pipe is threaded through the traditional method. Must be scrapped, resulting in waste of formwork
In addition, the verticality of the pre-embedded pipe is difficult to control. The connection between the pre-embedded pipe and the bottom formwork is hinged. bit
This is mainly caused by the vibrating rod vibrating the concrete, so that the position and verticality of the embedded pipe cannot be effectively controlled
Furthermore, it is easy to affect the quality of concrete molding. The diameter of the bottom mold hole is larger than the outer diameter of the embedded pipe, and grout leakage is prone to occur when concrete is poured, because concrete is a mixture of fluid, that is, aggregate and slurry, and the slurry at this time will It flows out from the gap between the embedded pipe and the bottom mold hole, and only the aggregate is left here, which affects the quality of concrete molding.

Embodiment Construction
[0016] From figure 1 , 2 It can be seen that the special positioning sleeve 1 includes a base 3 and a tube body 2 on it. The tube body 2 is formed with a matching inner cavity. There is a circle of protrusions 4 on the inner cavity wall. Each of the three corners has a screw hole 5 . When in use, the sleeve 1 is fixed on the template 4 by screws, and then the pre-embedded line tube 2 is inserted into the upper inner cavity of the positioning sleeve 1, and the position can be limited by the stopper bump 4. After the template is removed , and then insert the pre-embedded thread through the lower floor into the lower inner cavity of the positioning sleeve 1, so that each floor is connected through the pre-embedded pipe. If you need to change the position, you only need to remove the screw, and then Just re-fix the base. Compared with the traditional technology, it saves a lot of pre-embedded pipes.
[0017] The above implementation examples are only preferred embodiments of t...

Abstract
The invention relates to an electrical engineering pre-buried positioning sleeve, aiming at disclosing an electrical engineering positioning installation sleeve which is not easy to damage a template, can effectively control the position of a pre-buried pipe and can improve the concrete quality. The electrical engineering positioning installation sleeve effectively solves the technical problems that the template is easy to scrap, the position of the pre-buried pipe is difficult to control and the concrete quality is difficult to improve. The adopted mold can be fixed only through screws without drilling holes on the template, and the manual cost is saved.
Description
technical field [0001] The invention relates to the technical field of electrical installation in construction engineering, in particular to a pre-embedded positioning sleeve for electrical engineering. Background technique [0002] In the construction process of a multi-storey building, the power supply wires are usually connected to the building from the ground floor, and then connected to each floor through the floor slab of each floor. According to relevant electrical installation specifications, electrical lines must be covered with casings, that is, electrical outer pipes must be pre-embedded at the same time as concrete construction. Through the middle, the conventional method is to open a hole in the bottom form of the beam, the diameter is slightly larger than the outer diameter of the pipe, and the lower end passes through the bottom of the bottom form, and the middle and upper parts are fixed on the upper part of the steel bar. Among the buried pipes, it is neces...
