1. The installation plan and connection form of the support should be specifically negotiated with the structural designer to ensure the reliable connection and function of the upper and lower structures and the support.
2. The label of the lower reinforced concrete column shall not be lower than C40.
3. The reinforcement in the column should refer to the research and analysis results during the design of this support, that is, within the height range of 0.25b to 0.6b from the top of the column along the direction of the column axis to the column foot (b is the width of the column section), increase For the configuration of the horizontal stirrup section, the amount of increase is determined based on the results of the bearing capacity analysis.
4. The movable support sets the offset value between the upper support plate and the sliding plate according to the design requirements.
5. If the connection between the support and the embedded steel plate is welded, cooling measures or intermittent welding should be taken to prevent the support steel from overheating and damaging the PTFE plate, rubber sealing ring, and 5201 silicone grease.

6. Before installation, the elevation and levelness of the substructure should meet the design requirements. The height difference between the four corners of the support is not more than 1mm.
7. The centerline of the support should coincide with the centerline of the main beam and the installation line of the substructure.
8. After the support is installed in place, the welding of the bottom plate and the embedded steel plate meets the design requirements. After the construction of the beam body is completed, the temporary connectors should be removed immediately.
9. When the support is installed, the connecting parts of the upper support plate and the lower support plate must be installed. After the support is installed in place, remove it, and install the dust cover immediately (the dust cover is a rubber plate, the same as the site The construction unit is responsible for installation).
