An anti-leakage method for stress crack control of steel-concrete main structure

Abstract

The invention discloses an anti-leakage method for controlling stress cracks of a steel-concrete main structure, which belongs to the technical field of building construction. An anti-leakage method for controlling stress cracks of a steel-concrete main structure, the method is realized based on an anti-leakage device for controlling stress cracks of a steel-concrete main structure, and the anti-leakage device for controlling stress cracks of a steel-concrete main structure Including the wall, the middle position of the lower side inside the mechanical box is rotatably connected with a hollow shaft, the rear end of the sleeve extends through the inner wall of the mechanical box to the inside of the circular groove and is sleeved with a rotating block, and the middle part of the outer wall of the ring rack is equipped with a guide rail , There is an empty slot in the middle of the front side of the limit block, and there is a flat scraper through the shaft hinge inside the empty slot. The close cooperation between the structures makes the two actions can be carried out continuously, effectively saving manpower and material resources, and making the scraping more uniform , to avoid the leakage of water from the cracks to other households, and the occurrence of cracks has caused great distress to the residents.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-leakage method for controlling stress cracks of a steel-concrete main structure. Background technique [0002] In recent years, in the field of reinforced concrete structures, surface cracks after pouring of concrete structures have become a relatively common quality problem and a technical problem that needs to be solved urgently. Since the damage and collapse of structures under the action of external loads starts from the expansion of cracks, it is understandable that people often have a sense of fear of building damage to cracks. However, the appearance of a large number of cracks is not directly related to the load. Through a large number of investigations and field measurements, it has been proved that such cracks are caused by deformation, including temperature deformation, shrinkage deformation and uneven settlement deformation of the foundation.

Problems solved by technology

However, with the rapid development of high-rise buildings in today's society, especially in residential buildings, stress cracks can be seen everywhere, causing water to leak from the cracks to other residents. Concrete or glue is poured into the cracks to prevent leakage. However, the existing technology uses a scraper and glue to pour glue into the cracks for repeated scraping, which is time-consuming and laborious. Moreover, for cracks at high places, it is more necessary to build a high platform for processing, the operation is cumbersome, and there is a great potential safety hazard. In addition, other existing anti-leakage devices cannot simultaneously realize the actions of rotating scraping and telescopic material collection, such as CN108149907, which requires An additional dual-function module is used to connect the two processes, so this design has the disadvantages of large structure and bulky equipment
