Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction crack reinforcement device. Background Art

[0002] After long-term use, buildings (such as bridges, houses, etc.) will experience a decrease in bearing capacity due to various reasons. This is mainly manifested in cracks in the walls of old buildings (or bridges) due to settlement and other reasons. In order to reinforce the walls of buildings with cracks, crack reinforcement devices are usually used to fix the width of the cracks to reinforce the walls. In some existing devices, the two reinforcement plates are tightened by a rope to limit the cracks. However, the rope is prone to breakage when subjected to the tension of the two walls, and the angle of the fixing device cannot be adjusted according to the randomness of the cracks, which is not conducive to reinforcing the cracked walls.

[0011] In the present invention, the device is placed above the cracked wall. First, the fixed plate is rotated according to the angle of the crack. The bearing on the inner side of the fixed plate rotates relative to the connecting seat. After the angle of the fixed plate is adjusted, the operating handle is rotated to drive the threaded rod to rotate. The limit sleeve threadedly connected to the outer side of the threaded rod slides along the threaded rod under the traction of the thread. Since the limit sleeve is rotatably connected to the inner side of the connecting seat, the connecting seat on one side slides along the limit rod. After the distance adjustment is completed, the fixed block is pressed down by external power, and the punch drill fixedly connected below the fixed block is inserted into the wall until the suction cup of the limit connection below the fixed plate contacts the wall surface.
