Combined embedded sleeve pipe

Abstract

The invention discloses a combined embedded sleeve pipe. The combined embedded sleeve pipe comprises an inner pipe and an outer pipe which are coaxially arranged, wherein the inner pipe is arranged inside the outer pipe, and the inner pipe and the outer pipe can move relatively; female and male buckles matched with each other are arranged on the outer circumference of the outer pipe, and the female buckles and the male buckles are respectively positioned on the upper side and the lower side of the radial section of the outer pipe; and fixed wings are arranged at the ends of the inner pipe andthe outer pipe. After the embedded sleeve pipe is subjected to factory prefabrication processing, the embedded sleeve pipes can be freely assembled on site according to construction site conditions and construction drawing requirements, the conventional on-site welding process is effectively solved, on-site management and control are facilitated, and meanwhile construction cost is greatly saved.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and particularly relates to a combined pre-embedded casing. Background technique [0002] In the electromechanical installation engineering, all kinds of pipelines and line pipes need to be embedded in the casing according to the size of the pipeline diameter and the coordinates of the installation location during the construction of the structure when crossing the floor, wall, beam and column. Due to the different pipe diameters of various types of pipelines and line pipes, the thickness between floors, walls, beams and columns is also different, which makes the diameter and length of each embedded casing different, and the embedded casing needs to be made targeted Processing, which greatly increases the difficulty of casing prefabrication and labor costs. At the same time, because each embedded casing is also easy to be confused, even if the embedded casing is numbered, it needs to be...

AI Technical Summary

Problems solved by technology

Due to the different diameters of various pipes and line pipes, the thickness of floors, walls, and beams and columns is also different, which makes the diameter and length of each embedded casing different, and the embedded casing needs to be made in a targeted manner Processing, which greatly increases the prefabrication difficulty and labor cost of casing

At the same time, since the various pre-embedded casings are easy to be confused, even if the embedded casings are numbered, they need to be sorted and selected during construction. Once a processing error occurs, emergency treatment is required, which greatly increases the difficulty of installation and is time-consuming. and will affect the construction quality
