AI Technical Summary

Technical Problem

The construction quality of existing fiber-reinforced cement boards is insufficient, which makes the boards prone to loosening, warping, and deformation, affecting the pressure relief effect and service life. Especially in the complex environment of chemical plant buildings, stress accumulation at the joints leads to cracking and detachment, affecting the airtightness and waterproof performance of the wall.

Method used

Countersunk screws are used to fix fiber-reinforced cement boards, forming a double-layer synergistic load-bearing structure. Water-resistant flexible putty is filled at the joints and fiberglass mesh is attached. Combined with U-shaped steel constraints, the joint structure is optimized to buffer deformation and disperse external forces.

Benefits of technology

It significantly improves the overall connection and deformation resistance of the panels and keel, prevents joint cracking and rainwater leakage, extends the service life of the pressure relief wall, and ensures the high strength, durability and reliable pressure relief function of the lightweight pressure relief wall in the chemical plant.

Abstract

The application discloses a construction method for improving the strength of fiber reinforced cement boards and relates to the field of building construction; the construction method for improving the strength of fiber reinforced cement boards effectively solves the problems of easy loosening, edge warping and deformation of the board under the traditional single-board fixing mode, significantly improves the overall connectivity of the board and the keel and the anti-deformation capacity of the wall, and forms a double-board cooperative stress structure by connecting long U-shaped steel to the inner side of the fiber reinforced cement board joint and by jointly restraining the edges of the adjacent boards on the keel; meanwhile, the water-resistant flexible putty is filled and pressed into the glass fiber mesh belt at the joint of the outer board, which not only can offset the joint stress of the fiber reinforced cement board caused by dry shrinkage, wet expansion and temperature change, prevent the putty layer from cracking and rainwater leakage, but also avoids forming a rigid filling layer to hinder the normal pressure relief of the wall.
