Deformation joint installation method Why install deformation joint

Deformation joint installation will be carried out in many buildings. The installation method is usually complicated. What are the installation methods of deformation joints? Why should we install deformation joints in buildings? Describe the installation method of deformation joints and why deformation joints should be installed.

First, the six methods of deformation joint installation

1. We need to check whether the notch meets the installation requirements before installation. If it does not meet the requirement, we can make up the excess notches or fill in the missing notches. If the notches are too deep or too wide, we can Use straight ribs in deep or wide sections for reinforcement. Ensure that the slots are straight and strong.

2. We also need to check whether the floor deformation joint device conforms to the design drawing structure. If it does not, we need to make a groove or abutment, and use M6 expansion bolts embedded in the reinforced concrete main structure. The minimum depth is 40mm. If the M8 expansion screw is used, it should be buried more than 50mm. The groove or abutment should be fixed to the reinforced concrete main structure.

3, we need to install according to the requirements of the design drawings, with the center of the deformation joints as the starting point, to determine the location of fixed aluminum alloy base and expansion bolts on both sides, their spacing should meet the installation requirements.

4, then we can install the fire resistance belt according to the actual situation, and then we need to use the special adhesive on both sides of the gap with the side of the base and the water stop, and will be the level of the water stop in the compaction In the concrete base layer, there must be no bubbles, cracks, etc. in their connecting parts.

5, then we can put the aluminum alloy base near the slot, and to adjust the elevation so that its longitudinal slope, cross-slope and decorative surface consistent, and then it is fixed.

6. The requirements for installation of design drawings shall be such that the slide bar is fixed and fixed, and then the panel is changed and fixed. The cover of the deformation joint device shall be consistent with the longitudinal slope and horizontal slope of the floor. Then according to the needs of the plastic strips, marble and other materials filled in, the seams are best to use caulking glue, and do a good deal of scraping, to protect the finished product.

Second, why to install deformation joints

Deformation joints are generally classified into three types: expansion joints, settlement joints and seismic joints. Expansion joints are installed to prevent building components from expanding and contracting due to excessive temperature differences. The anti-seismic joints, as their name suggests, are designed to prevent buildings from being damaged due to the overall vibration caused by earthquakes. As for the settlement joints, it is to prevent uneven building settlement caused by uneven load, resulting in wall cracking.

Xiao Bian concludes: Regarding the deformation joint installation method and why it is necessary to install deformation joint Xiao Bian, it is briefly introduced here. I hope that after reading this paper, I can provide you with reference and help.
