1results about How to "Guaranteed grounding effect" patented technology

This utility model provides a prestressed concrete slab construction support, belonging to the field of building construction. Its technical solution includes a base and a support frame mounted on the base. The support frame includes a lower U-shaped support plate, with upper U-shaped support plates symmetrically arranged on the top of the side plates on both sides of the lower U-shaped support plate. A lower layer of transverse corrugated pipe is arranged in the lower U-shaped support plate, and upper layer of longitudinal corrugated pipe is arranged in the upper U-shaped support plates on both sides. The support frame includes an annular frame, with L-shaped support legs at the four corners of the annular frame. A protrusion is provided at the bottom of the lower U-shaped support plate, and the protrusion is located within the annular frame. The beneficial effects of this utility model are: by using an integrally molded plastic support frame, it can provide excellent insulation, preventing conductivity through the support frame, thus eliminating the need for separate grounding of the support frame. Simultaneously, it can separate the upper and lower corrugated pipes, allowing each pipe to be grounded independently, ensuring effective grounding.
