Fireproof plugging member for cable

Abstract

The invention provides a fireproof plugging member for a cable. The fireproof plugging member comprises a clamping frame and a plurality of block bodies filled in the clamping frame, wherein at least one matching mechanism is arranged between adjacent block bodies which are matched with each other; and the matching mechanism comprises convex blocks which are transversely arranged on the peripheral region of the block bodies and grooves which are transversely formed on the peripheral region of the adjacent block bodies and matched with the convex blocks. During installation, the convex blocks are matched with the corresponding grooves. During the occurrence of fire, the fireproof plugging member is expanded at high temperature so that the convex blocks are closely matched with the grooves to avoid the block bodies from jumping out of the wall and prevent damage to the human body. Therefore, the security of the fireproof plugging member is greatly improved and the fire resistance of the fireproof plugging member is ensured. In addition, the fireproof plugging member is simple in structure.

Description

technical field [0001] The invention relates to a fireproof sealing member, in particular to a cable fireproof sealing for sealing a penetrating opening, and belongs to the technical field of fireproof materials. Background technique [0002] With the development of society, there are more and more houses and buildings. In order to ensure the safety of the building, when the penetrating objects (such as cables, air ducts, etc.) pass through the wall, the openings on the wall must be sealed with fireproof seals to prevent fires The spread of fire from one subdivision to another and the spread of toxic fumes. When the cable runs through the wall or hole, the original protective integrity of the wall is destroyed, which is easy to cause the spread of fire. [0003] In order to solve this technical problem, the opening where the cable runs through the wall is usually sealed with a fireproof sealing member to prevent the fire from spreading. The existing fireproof sealing memb...

AI Technical Summary

Problems solved by technology

The existing fireproof sealing member includes a clamping frame and a plurality of blocks filling the clamping frame, the mating surfaces of the adjacent blocks are plane, and the fireproof sealing member of this structure, when a fire occurs When it happens, the fireproof sealing member will expand when it encounters high temperature, and the radial direction of the fireproof sealing member is clamped by the clamping frame, so it cannot deform, but can only deform along the axial direction, because the mating surface of the block When the deformation reaches a certain level, the block will pop out of the wall, which will not only make the wall not tightly sealed and cause more serious safety accidents, but also cause harm to the human body. ; Therefore, the safety of the existing cable fire blocking member is relatively poor
