Description

Technical Field

When in use, the support rod is set on a supporting surface such as the ground, and the top plate is aligned with the hole and set under the floor slab, and then concrete is poured to seal the hole. This method usually requires measuring the height between the floor slab and the supporting surface first, and then producing and processing support rods of corresponding height based on the measured height. However, due to the inevitable errors in measurement, the support rods cannot achieve height matching during on-site construction, and it is necessary to cut or install gaskets on site to compensate for the errors, which makes construction inconvenient.
