AI Technical Summary

Technical Problem

When using foaming agent for traditional screw eye sealing methods for exterior walls of high-rise buildings, the foaming agent is prone to aging and cracking, affecting the sealing effect and reducing the effectiveness of the structure.

Method used

A screw eye sealing structure including a shell, a pushing plate, a tooth seat, a gear column, a rotary plate, a waterproof expansion plate and a locking mechanism is adopted. The waterproof expansion plate is driven by pushing the plate and gear system to tightly seal the holes and improve the fixing effect of the structure through the locking mechanism.

Benefits of technology

It realizes efficient sealing of screw holes, improves waterproof performance and structural stability, and avoids the problem of reducing sealing effect caused by aging of foaming agents.

Abstract

The utility model relates to the technical field of building construction, and discloses a high-rise building outer wall screw hole plugging structure which comprises a shell, a pushing plate is slidably installed on the inner bottom wall of the shell, tooth holders are fixedly connected to the front side and the rear side of the pushing plate respectively, gear columns are rotationally connected to the front side and the rear side of the inner wall of the shell respectively, and the gear columns are fixedly connected to the inner wall of the shell. The two gear columns are connected with the corresponding tooth holders in a meshed mode, the adjacent sides of the two gear columns are fixedly connected with rotating plates, the sides, away from each other, of the two rotating plates are rotationally connected with waterproof expansion plates, and the left sides of the two waterproof expansion plates are rotationally connected with the upper side and the lower side of the shell through rotating hinges. According to the device, the structure is pushed towards the interior of the wall, the fixing plate makes contact with the pushing plate, the fixing plate drives the two tooth holders to move forwards, the two gear columns rotate in the directions away from each other, and therefore the two waterproof expansion plates are turned over and expanded, holes are blocked, and an operator can use the device conveniently.
