Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The fire-proof structure of the water pipe through-wall at the piping shaft according to the embodiment of the present invention will be described in detail with reference to fig. 1 to 3.

Example (b):

the embodiment of the utility model provides a fire resistive construction of pipe shaft department water pipe through-wall, refer to fig. 1 and show, including pipe shaft 1, be provided with sleeve pipe 2 in pipe shaft 1's the wall body, it has water piping 3 to run through in the sleeve pipe 2, there is main water supply pipe 4 through pipe support connection on pipe shaft 1's the inner wall, water piping 3's the end of intaking and main water supply pipe 4 intercommunication, water piping 3's play water end intercommunication has indoor waterway system 5, this structure is through setting up sleeve pipe 2 on pipe shaft 1, it is indoor to utilize sleeve pipe 2 to communicate pipe shaft 1, then the sleeve pipe can be passed to water piping 3, thereby communicate with indoor waterway system 5, and then send into indoor waterway system 5 with the water in the main water supply pipe 4.

Referring to fig. 2 and 3, a cement-proof layer 6 is arranged between the water pipe 3 and the casing pipe 2, and the two ends of the opening of the wall-through part of the water pipe 3 are plugged by a fireproof sealant 7, so that the gap between the water pipe 3 and the casing pipe 2 is filled with the cement-proof layer 6, and the water pipe 3 and the casing pipe 2 cannot be penetrated into the pipe shaft 1 from the gap between the water pipe 3 and the casing pipe 2, and the fireproof sealant 7 is matched to further improve fireproof tightness and fireproof performance.
