Reinforcing and repairing structure for opening hole behind basement wall of civil air defense project

Abstract

The invention relates to the related technical field of civil air defense engineering repair, in particular to a civil air defense engineering basement wall back opening reinforcing and repairing structure which is used for repairing a wall opening in a wall and comprises an embedded part and a plugging part. The embedded part is inserted into a wall hole and comprises a supporting arc-shaped steel plate, a plurality of first arc-shaped steel plates and a plurality of second arc-shaped steel plates, the circle centers of the first arc-shaped steel plates and the circle centers of the second arc-shaped steel plates are the same, the first arc-shaped steel plates are distributed in the circumferential direction of the wall hole at intervals, and a circular filling cavity is defined by the first arc-shaped steel plates. A second arc-shaped steel plate is arranged at the interval between every two adjacent first arc-shaped steel plates, arc-shaped sliding grooves are formed in the shell walls of the first arc-shaped steel plates, and every two adjacent arc-shaped sliding grooves are in sliding connection with the two ends of the corresponding second arc-shaped steel plate correspondingly; and the diameter of the filling cavity can be adjusted by adjusting the distance between the multiple first arc-shaped steel plates and the center of the filling cavity, and the function of repairing wall holes with different calibers is achieved.

Description

technical field [0001] The invention relates to the related technical field of civil air defense engineering repair, and more particularly relates to a rear opening reinforcement and repair structure of a basement wall of civil air defense engineering. Background technique [0002] Civil air defense engineering refers to the underground protective buildings built separately to protect personnel, material shelter and medical aid during wartime, as well as basements built in combination with ground buildings that can be used for air defense during wartime. [0003] In the process of repairing the wall hole on the wall of the civil air defense project, it is necessary to fill and redo the wall hole or expand the wall hole to expose the steel bars before filling, and connect the steel bars on both sides of the hole to ensure the resistance of the wall after filling. Tension; the traditional way to connect the steel bars on both sides of the hole is to cut the connecting steel ba...

[0003] In the process of repairing the wall hole on the civil air defense project, it is necessary to fill the wall hole again or expand the wall hole to expose the steel bars before filling, and then connect the steel bars on both sides of the hole to ensure the resistance of the wall after filling. tension; the traditional way to connect the steel bars on both sides of the hole is to first cut the connecting steel bar according to the distance between the ends of the two steel bars, and then weld the connecting steel bar to the ends of the steel bars on both sides of the hole. Internal connection, such a repair method has the problem of troublesome operation and long time-consuming
