A Restoration Construction Method of Pre-roofing by Opening Hole of Broken Wall of Masonry Structure

Abstract

The invention relates to a brickwork structure wall-breaking and hole-forming pre-jacking recovery construction method. The brickwork structure wall-breaking and hole-forming pre-jacking recovery construction method comprises the following steps that 1, holes are cleared and pretreated; 2, new walls are built in the holes; 3, when the distances between the top faces of the built new walls and thetops of the holes reach set values, buried-in-type controllable unloaders are mounted between the top faces of the built new walls and the tops of the holes; 4, gaps between the built new walls and old walls around the holes are grouted for closing; and 5, finally, the closed holes are subjected to formwork removal and curing. According to the brickwork structure wall-breaking and hole-forming pre-jacking recovery construction method, compact connection of the new walls and the old walls at the holes can be ensured, the new walls built at the holes are preloaded by arranging the buried-in-typecontrollable unloaders, the load transmitting paths of the building walls are effectively recovered, the safety and reliability of hole recovery are improved, thus the structural safety of a buildingis ensured, and the potential safety hazard is effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for opening and pre-roofing a broken wall of a masonry structure. Background technique [0002] At present, there are still many holes in the load-bearing walls of buildings with masonry structures (especially residential buildings). The building collapsed, resulting in casualties. In order to ensure the safety of the occupants, it is very necessary to effectively restore the hole in the broken wall. [0003] The opening of broken walls in residential houses is usually done by directly chiseling away the brick walls to form rectangular door openings or window openings. Unconsidered restoration is to directly arrange workers to lay flat from the bottom of the opening, and start laying flat until it is about 20 centimeters from the top of the opening. Lay obliquely, until the opening of the hole is closed, it is completed. This met...

Problems solved by technology

This method of simply closing the opening with masonry does not mean that the wall has been densely built, and the load (weight) of the upper wall of the opening cannot be effectively transmitted to the rear wall, and the structural safety of the building has not been restored. The original level, so the building still has structural safety hazards
