AI Technical Summary

Technical Problem

Pre-buried wire conduits are prone to displacement in concrete structures, resulting in a reduction in structural cross-section, forming weak areas, causing stress concentration and cracking, and affecting structural durability. Existing technologies make it difficult to accurately fix and enhance the structural strength around the wire conduits.

Method used

The pre-buried wire pipe mesh bracket is composed of several parallel steel rings and steel bars. The steel rings are welded to the steel bars to form a channel. The space between the steel rings is larger than the size of the coarse aggregate of concrete. The steel bars can be bent to adapt to the direction of the wire pipe and are fixed to the steel mesh with iron wire to ensure the accurate position of the wire pipe and enhance the structural strength.

Benefits of technology

It achieves accurate positioning of pre-buried wire conduits, reduces the risk of cracking, improves structural durability, adapts to different pipe diameters, and is flexible in construction. It can be used in prefabricated and cast-in-place concrete structures.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a pre-buried wire pipe net support. Background Art

[0002] Floor cracking caused by pre-buried conduits running to the edge of the structure and weakening the structural cross-section is common in building structures. Currently, pre-buried electrical wiring within concrete structures is commonly used to meet both functional and aesthetic requirements. Typically, various conduits are pre-buried in the middle of the concrete floor slab and fixed to the steel skeleton or formwork at intervals. These pre-buried conduits reduce the local structural cross-section along the line, creating a weak section. Under load, the concrete structure around the wall of the concealed conduit will experience stress concentration cracking, especially when the conduit runs loose and runs to the edge of the structure (such as the lower part of the floor slab) due to insufficient fixing points. This situation can easily lead to irreversible structural cracking along the conduit, resulting in common problems such as structural penetration, water seepage, and corroded steel bars, reducing the durability of the structure. Later reinforcement and repairs can only be carried out with structural reinforcement, which is difficult to cure and affects normal use during repairs. Summary of the Invention

[0003] The object of the present invention is to provide a pre-buried wire pipe net bracket that can overcome one or more of the above-mentioned shortcomings, and provide a pre-buried wire pipe net bracket that can support and fix the pre-buried electrical wire pipe in the building structure along the wire pipe, ensure that the pre-buried wire pipe is accurately positioned and does not move, and is flexible in construction. It can accurately enhance the crack resistance of the concrete structure around the wire pipe along the wire pipe, improve the durability of the structure, and reduce the probability of cracking of the structure along the wire pipe.

[0004] The pre-buried wire pipe mesh bracket of the present invention is realized as follows: it includes several parallel steel rings and one or more steel bars connecting the several steel rings in series. The steel rings are welded to the steel bars so that the several steel rings connected in series form a channel for the wire pipe to pass through, and the space size between the steel rings is larger than the size of the concrete coarse aggregate.

[0005] Preferably, the steel bar is serpentine or straight. By adopting the serpentine steel bar, the steel bar can be easily extended and retracted, so that the pre-buried wire pipe net bracket can be bent according to the direction of the wire pipe.

[0006] Preferably, the serpentine steel bars form a plane, with three serpentine steel bars arranged in a triangular pattern on the steel ring. Thus, by adjusting the width of the serpentine steel bar plane, the spacing between the three serpentine steel bars can be adjusted to accommodate the threading requirements of conduits of varying diameters.

[0007] During construction and installation, according to the pipe diameter requirements of the pre-buried wire pipe, the pre-buried wire pipe is inserted into the pre-buried wire pipe mesh bracket of the technology of the present invention in sections or as a whole outside the front site, so that the pre-buried wire pipe mesh bracket and the wire pipe form an integrated wire pipe, and the total length of the pre-buried wire pipe mesh bracket (which can be spliced ​​in multiple sections) matches the wire pipe. After the formwork project is completed, according to the actual situation of the construction and installation site, when the steel bars on the bottom surface of the floor are tied, the prepared integrated wire pipe is laid on the steel mesh on the bottom surface of the floor and the floor surface reinforcement is tied to cover it. Then, the integrated wire pipe is fixed to the appropriate position between the upper and lower steel meshes with wire. After the laying is completed, wait for acceptance and then pour concrete.

[0008] The space between the steel rings is larger than the size of the concrete coarse aggregate. In this way, the concrete mixed with the concrete coarse aggregate can be smoothly filled into the steel rings and the space between the steel rings.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. The pre-buried wire pipe net bracket can effectively support the fixed position along the wire pipe, ensuring the accurate position of the pre-buried wire pipe without displacement, and eliminating the quality risk of insufficient fixing points, loosening and displacement.

[0011] 2. Solve the problem of difficult to accurately reinforce the structure of pre-buried conduit due to random layout. The pre-buried conduit mesh bracket can enhance the structural strength of the surrounding pre-buried conduit and reduce the probability of cracking along the conduit structure.

[0012] 3. The length of the pre-buried wire pipe net bracket can be freely cut according to the actual situation of the wire pipe. The length can be freely spliced ​​without affecting the effect, and the construction is flexible.

[0013] 4. The pre-buried wire pipe net bracket is applicable to pre-buried wire pipes in prefabricated concrete structures and cast-in-place concrete structures, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
