Embodiment 1

[0042] Such as figure 1 , 2 As shown, a cable wall penetration structure includes a cable 1 and an energy dissipation pipe 3 passing through a wall 2. The wall 2 can be a building wall 2 or a partition wall of a comprehensive pipe gallery, and the wall 2 is provided with The perforation 21 , the energy dissipation pipe 3 is perforated in the perforation 21 . The energy dissipation pipe 3 can be made of steel or PVC.

[0043] Such as image 3 As shown, the energy dissipation pipe 3 includes an outer pipe 31 and an inner pipe 32 passing through the outer pipe 31 , and the cable 1 is passed through the inner pipe 32 . The outer tube 31 includes two side plates 311 , and two side plates 311 are located at both ends of the outer tube 31 . The side plate 311 can be fixed to the end of the outer tube 31 by bolts, or can be welded or bonded to the end of the outer tube 31 . The side plate 311 is provided with an opening 3111 , and the opening 3111 is arranged in the middle of the...

Embodiment 2

[0055] A construction method for cable 1 through walls, comprising the following steps:

[0056] S1. After the reinforcement of the wall 2 is bound, fix the energy dissipation pipe 3 to the corresponding position of the wall 2;

[0057] S2, pouring the concrete of body of wall 2 and curing;

[0058] S3. Set the cable 1 in the inner tube 32 to complete the installation and fixing of the cable 1 .

[0059] After the energy dissipating tube 3 is installed, the cable 1 is passed through the inner tube 32 of the energy dissipating tube 3. The energy dissipating tube 3 plays a role in protecting the cable 1, reducing the impact on the cable 1 and prolonging the service life of the cable 1.

Abstract

The invention relates to a cable wall penetration structure, which belongs to the technical field of cable penetration, including a cable, and an energy dissipation tube passing through the wall. The energy dissipation tube includes an outer tube and an inner tube passing through the outer tube. The cable is passed through the inner tube, and the outer tube includes side plates; two side plates are arranged at both ends of the outer tube, the side plates are provided with openings, and the gap between the inner tube and the outer tube is connected by elastic components. When the wall is impacted and vibrated, the outer tube transmits the impact force to the inner tube through the elastic component, and at the same time plays the role of vibration reduction and energy absorption. The inner tube can be displaced within a certain range in the outer tube to consume the impact force and reduce The impact on the cable in the inner tube can effectively reduce the damage of the cable and prolong the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of cable penetration through walls, in particular to a cable penetration through wall structure and a wall penetration construction method thereof. Background technique [0002] At present, when the cables pass through the outer wall of the structure, a wall hole needs to be provided. In the prior art, the PVC pipe is usually pre-placed before the concrete pouring of the external wall, the diameter of the pipe is determined according to the diameter of the cable, and the length of the pipe is the same as the thickness of the wall. After the concrete is poured, a wall-through hole is formed on the outer wall, and the cable passes through the hole and is sealed with fire-proof plugging mud. [0003] The Chinese patent with application publication number CN108808594A discloses a grouted and sealed cable wall casing structure and its construction method, including cables, which are arranged in the casing body a...
