Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire prevention of civil air defense projects, in particular to a fireproof blocking structure. Background Art
[0002] As we all know, civil air defense projects are a special underground building with protection requirements. There are several common classification methods: according to the resistance level, the project can be directly called a certain level of civil air defense project; according to wartime use, it can be divided into command and communication, personnel shelter, hospital, first aid station, warehouse, garage, etc.; according to peacetime use, it can be divided into shopping malls, amusement parks, hotels, theaters (halls), etc.; from the construction method of the project, it is divided into two categories: excavation project and pit tunnel project. The use of firewalls is indispensable for civil air defense projects, but laying cables requires opening wire holes on the firewall, which will reduce the fire resistance of the firewall. Therefore, a fireproof blocking structure is proposed to solve this problem.
[0003] The current fireproof blocking structure mainly uses blocking materials to directly block the wire threading holes. However, when replacing cables without a fire, the blocking materials need to be removed and then blocked in the wire threading holes after the cables are replaced. Therefore, it is very inconvenient to replace the cables every time. Therefore, it is necessary to improve the existing technology. Utility Model Content
[0004] 1. Technical issues to be solved
[0005] In view of the deficiencies of the prior art, the utility model provides a fireproof blocking structure, which is convenient for workers to replace cables.
[0006] (II) Technical solution
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fireproof blocking structure, comprising a wall and a wire threading hole opened on the wall, a wire threading tube is installed in the wire threading hole, both ends of the wire threading tube are provided with connecting heads, a blocking net is arranged inside the wire threading tube, and a blocking material is filled between the blocking net and the wire threading tube.
[0008] Furthermore, a connecting plate is provided at the end of one of the connecting heads, a plurality of through holes are provided on the connecting plate, and a bolt is installed inside each through hole.
[0009] Furthermore, holes for installing bolts are provided on the wall.
[0010] Furthermore, the inner diameter of each connector gradually increases from a side close to the threading tube to a side away from the threading tube.
[0011] Furthermore, the blocking material is a heat-expandable fireproof blocking material.
[0012] Furthermore, the barrier is made of hard material.
[0013] (III) Beneficial effects
[0014] Compared with the prior art, the utility model provides a fireproof blocking structure, which has the following beneficial effects:
[0015] The fireproof blocking structure is provided with a wire threading tube and a connector. Each time the wire is replaced, the wire can be directly threaded in the wire threading tube. The inner diameter of the connector gradually increases from the side close to the wire threading tube to the side away from the wire threading tube, so that it is convenient to thread the wire into the wire threading tube. Through the blocking material and the blocking net, when a fire occurs, the blocking material expands due to heat and passes through the blocking net to seal the inside of the wire threading tube. When the blocking material does not expand due to heat, it is filled between the blocking net and the wire threading tube. Therefore, when no fire occurs, the staff can directly thread the wire in the wire threading tube, thereby facilitating the staff to replace the cables. BRIEF DESCRIPTION OF THE DRAWINGS
