Problems solved by technology

However, firstly, special molds are required, secondly, special tools are required for use, thirdly, the impact force is relatively large when taking out the catheter, and the material of the PVC pipe is relatively soft, so it is easy to deform or damage after repeated use

Embodiment Construction

[0018] Such as figure 1 As shown, a recyclable wall-penetrating conduit of the present invention includes detachable arc-shaped block 1, arc-shaped block 2 and arc-shaped block 3 made of metal, and the metal material can be copper, iron , steel, aluminum, etc. On the inside of the arc block 1, arc block 2 and arc block 3, a plurality of articulated pipes 4 are welded along the axial direction, which can be articulated and connected to each other after being inserted into the pin shaft, such as figure 2 As shown, the arc block 1, the arc block 2 and the arc block 3 are combined to form a hollow cylinder. Wherein the end of the connecting pin 6 of the arc block 3 is bent into a ring. When used, it will be as figure 2 The present invention shown is embedded in the structure before the wall is poured or masonry. After the wall is poured or masonry is completed, the user can pull the ring at the end of the connecting pin 6 to draw it out, so that the arc block 3 and the arc bl...

Abstract

The invention relates to a recyclable wall conduit, which is characterized by comprising at least three separable arc blocks which can form a hollow cylinder after being combined, wherein the adjacent separable arc blocks are connected through a hinging device arranged on both inner edges of each separable arc block; and the hinging device of at least one separable arc block is the detachable hinging device. According to the technical scheme, the wall conduit is buried before concrete is poured, both ends of the conduit can be sealed by sealing strips, or the inner side of the conduit is filled with yarn. After the concrete is solidified, the sealing strips are broken or the yarn is taken out, a connection pin of the detachable hinging device is pulled out, and each separable arc block is taken out after being separated. The conduit is simple in structure, does not need special detaching tools, is easy to be detached, cannot be damaged, and is available when recycled for hundreds of times.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a wall-penetrating conduit for reserving holes on buildings. Background technique [0002] In the field of building construction, wall-penetrating conduits are widely used. For example, when pouring shear walls, thin-walled columns or columns, the tensioning screws of the formwork pass through the above-mentioned building structures to realize clamping. For the convenience of taking out the pull screw after the concrete is poured, it is necessary to add a sleeve to the pull screw to form a hole. In addition, when the scaffolding is installed and fixed, especially when it is attached to the lifting scaffolding, a large number of wall-penetrating screws need to be used, and the sleeves need to be pre-embedded in the concrete. The way usually adopted is disposable use with PVC pipe, causes a large amount of material wastes. Chinese patent ZL200820073739.5 "Circulation conduit ...
