Background

The steam-pressurized concrete has the advantages of high strength-to-mass ratio, bearing capacity, heat preservation, fire prevention, mildew prevention and the like, and can effectively shorten the construction period by mainly using the application forms of the steam-pressurized concrete building blocks and the steam-pressurized concrete plates. Taking a steam pressurized concrete plate as an example, the plate has the functions of structural bearing, fire prevention and heat preservation, and is mainly used for bearing shear walls, floor slabs, roof slabs, peripheral wall panels of frame structures, inner partition walls and the like of civil low-rise houses.

When the steam-pressurized concrete plate is assembled in a building as a wall, an assembly gap exists between the plates, and the assembly gap can reach 2-5 mm due to the size deviation of the plates. The assembly gaps not only obviously affect the quality of the wall body and reduce the heat preservation and silencing effect of the building and the bearing performance of the structure, but also can be developed into bearing stress concentration points of the wall body after thermal expansion and cold contraction over the years, so that the potential safety hazard of the building is formed.

In order to solve the hidden danger of the building, in the building construction process, a rectangular anti-cracking groove is cut on the end face between the plates during the assembly of the plates, and then anti-cracking end-sealing glue is coated in the anti-cracking groove, so that the end cracking phenomenon of the plates is effectively avoided, and the problems of heat preservation and silence and reduced structural bearing capacity caused by gaps between the assemblies are well solved. However, in the building construction, the anti-cracking grooves are processed on the end faces of the plates, and operators need to hold the grooving machine to perform manual cutting, so that the labor efficiency is low, the labor intensity is high, the building construction cost and the time cost are increased, and the construction efficiency of buildings is reduced.
