Masonry wall movement joint fireproof and heat-preserving structure and installation method thereof

Abstract

The invention provides a masonry wall movement joint fireproof and heat-preserving structure. An L-shaped fireproof inner plate and an L-shaped fireproof outer plate are arranged on the inner side of a wall and are fixedly connected to a base layer of the wall through tail wings. A slot type fireproof cover plate is further arranged on the surface of the inner side of the wall and is fixed to the fireproof inner plate through bolts. An L-shaped heat-preserving inner plate and an L-shaped heat-preserving outer plate are arranged on the outer side of the wall and are connected with the base layer of the wall through tail wings. A heat-preserving cover plate is further arranged on the surface of the outer side of the wall and is fixed to the heat-preserving inner plate through bolts. A torsion spring is arranged between the fireproof outer plate and the heat-preserving outer plate. Tongue-and-groove portions of the fireproof outer plate and the fireproof inner plate can be attached through tension of the torsion spring, and tongue-and-groove portions of the heat-preserving outer plate and the heat-preserving inner plate can be attached. Whether telescopic deformation or settlement deformation happens, the fireproof outer plate and the fireproof inner plate will not be separated from each other, and the heat-preserving outer plate and the heat-preserving inner plate will not be separated from each other.

Description

technical field [0001] The invention belongs to the construction field of deformation joints of buildings, in particular to a fire prevention and heat preservation structure of deformation joints of masonry walls and an installation method thereof. Background technique [0002] Building deformation joints are gaps set up by buildings to resist damage caused by temperature, subsidence, earthquakes, etc., but after setting deformation joints, the building is artificially divided into multiple monomers. The foundation, wall, floor, roof and other parts of the building have been disconnected. After the main components in the building are disconnected, when a fire breaks out inside the building, the deformation joints in the building wall will easily become the way for the fire to spread, posing a great threat to the buildings above the fire point. At the same time, after the wall is disconnected, the inside of the building is connected to the outside of the building, and the th...

AI Technical Summary

Problems solved by technology

At the same time, after the wall is disconnected, the inside of the building and the outside of the building are connected, and the insulation effect of the building wall is lost at this part, which affects the overall insulation effect of the building.

[0003] Some measures have been taken in the prior art to solve the above problems, but there are mainly the following problems: 1. The wall function requirements that the deformation joint structure can meet are relatively simple, either only have the function of fire prevention, or only have the function of heat preservation; 2. The structure of the deformation joint The form of adapting to the deformation is relatively simple, often only adapting to the expansion and contraction deformation, and cannot adapt to the settlement deformation
