Description

Technical Field

[0001] This utility model relates to the field of building electromechanical lightning protection and grounding technology, and in particular to a waterproof metal protective pipe for grounding trunk lines passing through floor slabs. Background Technology

[0002] In the construction process, the commonly used construction methods for grounding trunk lines are generally as follows:

[0003] (1) Directly embedded in concrete. This method violates Article 8.8.4 of the General Specification for Building Electrical and Intelligent Systems GB55024-2022, which states that when the grounding trunk line passes through walls, foundations, floors, etc., it should be protected by metal conduits. Unprotected grounding trunk lines are easily damaged or fall off due to accidental impacts, affecting the quality of lightning protection grounding.

[0004] (2) Using circular steel pipes for pre-embedding. This method addresses the issue of pre-embedding in the standard clauses. However, since the steel pipes are not effectively fixed, the positioning and fixing effect of the pre-embedding are affected. The pipe walls are smooth and do not have waterproof performance, making it easy to leak. Furthermore, there is no base plate support inside the steel pipes, and the embedded fireproof mud is prone to slipping, resulting in poor fireproof sealing and affecting the protection effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a waterproof metal protective pipe for grounding trunk lines that can overcome the defects of existing technologies, such as grounding trunk lines being easily damaged or falling off due to accidental impacts, easy leakage around the protective pipe, inadequate fireproof sealing, and inaccurate pre-embedded positioning.

[0007] Furthermore, the base plate is a circular steel plate.

[0008] Furthermore, there are four fixing holes, evenly distributed along the edge of the base plate; correspondingly, there are also four fixing nails.

[0009] Furthermore, the square hole for the grounding trunk line is located in the center of the base plate, leaving sufficient operating space for easy construction.

[0010] Furthermore, the waterproof ring is welded to the metal protective pipe 5cm above the bottom plate, which prevents water from the floor above from seeping into the lower layer through the gap between the metal protective pipe and the floor.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) By using the base plate, fixing holes, fixing nails, square holes for grounding main line, metal protective pipe, waterproof ring wing, bolt holes, bolts, bridging yellow-green double-color wire and grounding main line to form a stable structure, it can effectively solve the problems that the grounding main line is easily damaged or falls off due to accidental impact, the protective pipe is prone to leakage, the fireproof sealing is not tight, and the pre-embedded positioning is inaccurate.

[0013] (2) It has a simple structure, is easy to manufacture, can be processed in a factory, is sturdy and durable, is not easily damaged, can be manufactured and constructed in a standardized manner, can effectively overcome the quality defects of metal conduits for grounding trunk lines, and can improve the overall aesthetics.
