Movement joint is a device used to prevent cracks in the ground due to temperature changes. The function of the contraction joint is to provide a certain expansion space for the floor materials, such as marble and tile, so that they can freely expand and shrink without excessive stress. It is usually installed at the joint of the ground material, which can effectively absorb the expansion and deformation of the ground and keep the ground smooth and beautiful.
So, under what circumstances do you need to install movement joints indoors? There are the following situations:
-Install movement joints between different areas to disperse stress and deformation and reduce tile cracking, bulging, falling off and other problems.
-The indoor temperature changes greatly, resulting in the thermal expansion and contraction of the ground material is larger, and it is easy to produce cracks.
When the marble or tile is laid in a place where there are heating pipes or other temperature changes, it is necessary to install movement joints in the affected area to prevent cracking or deformation due to temperature differences.
- The indoor space is large, when the marble or tile laying area is large, the ground material has more joints, and the number and density of movement joints need to be increased to improve the stability and durability of the ground.
- Different types or colors of floor materials are used in the room, and movement joints need to be installed at the junction of materials to avoid cracks or misalignments due to different material properties.
- There are structures such as columns, corners, doors, and Windows in the interior, and it is necessary to install movement joints around the structures to reduce the influence and interference of the structures on the ground materials.
The width of the movement joint is generally determined according to different ground materials and laying methods. The filling material of the movement joint should be a material with good elasticity, strong water resistance and aging resistance, such as polyurethane glue and silicone glue. In short, the installation of movement joint is an important measure to ensure the service life and beauty of the ground.
