AI Technical Summary

Technical Problem

In the existing concrete panel formwork of geogrid reinforced soil retaining walls, the long length of the retaining rods leads to inconvenient transportation, high manpower consumption, and uneven stress on the formwork, bulging, and safety hazards during assembly.

Method used

The stop bar and fastening sleeve adopt a modular design. One end of the stop bar is provided with a locking slot. The fastening sleeve slides on the stop bar and is fixed by a locking ring. Adjacent stop bars are locked together and limited in position. Combined with the mounting base and sealing ring, a stable connection of the panel is achieved.

Benefits of technology

The shortening of the support bar length reduced the manpower required for transportation and assembly, improved transportation and construction efficiency, and enhanced the stability and safety of the formwork.

Abstract

The utility model relates to the technical field of building construction, and provides a concrete panel formwork for a geogrid reinforced earth retaining wall, which comprises a panel, a retaining rod and a fastening sleeve. And a plurality of panels are spliced in sequence to form a panel formwork. The plurality of stop levers are horizontally arranged on the surfaces of the panels and are in one-to-one correspondence with the panels, a bayonet is formed in one end of each stop lever, the other end of each stop lever is a clamping end, and after the two adjacent panels are spliced, the clamping end of one stop lever is clamped with the opening of the other stop lever of the two stop levers located on the two adjacent panels. The fastening sleeves are arranged on the stop rods in a sliding and sleeving mode and are close to the clamping ends of the stop rods, and after every two adjacent stop rods are clamped, the fastening sleeves can slide to the clamping openings so as to limit and fix the clamping portions of the two stop rods. By means of the technical scheme, the technical problem that in the prior art, due to the fact that a stop lever on a concrete panel is long, a large amount of manpower is needed in the transportation and assembly stages is solved.
