Deformation joints can be divided into three types: expansion joints, settlement joints, and shockproof joints. 02 02 02 02 Expansion joints: Building components expand and contract due to changes in temperature and humidity. To this end, vertical gaps are usually set up in appropriate parts of the building, and components such as walls, floor slabs, roofs and other components of the house are disconnected from above the foundation, and the building is separated into several independent parts. In order to overcome the excessive temperature difference, the foundation can be continuously opened, disconnecting from the top of the foundation to the roof along the structure. 02 02 02 Seismic joints: Seams set up to make the building more regular and conducive to the seismic resistance of the structure can be continuously opened. Its purpose is to separate large buildings into smaller parts, form relatively independent shockproof units, and avoid damage caused by the earthquake due to uncoordinated vibration of the building as a whole.
