AI Technical Summary

Technical Problem

The existing concrete support device for the guide wall of the underground continuous wall uses wooden supports, which have a single and unstable support point, making the formwork prone to displacement, affecting the flatness of the wall surface, and the installation and dismantling are complicated and inefficient.

Method used

The template uses a U-shaped frame, a two-way lead screw, and a top-tightening fixing component. It is supported and fixed by triangular clamps and compression to ensure the stability of the template, and achieves quick assembly and disassembly through gear meshing.

Benefits of technology

It improves the stability of the template, avoids template displacement during the pouring process, ensures the flatness of the wall surface, simplifies the installation and dismantling process, and improves construction efficiency.

Abstract

The utility model discloses a kind of underground continuous wall guide wall concrete supporting devices, it is related to building engineering technical field, and it includes: U-shaped frame, the both ends inner wall of U-shaped frame is connected with outside bidirectional screw rod by bearing, the both ends inner wall of U-shaped frame is connected with inside bidirectional screw rod by bearing.The utility model discloses a kind of underground continuous wall guide wall concrete supporting devices with every guide wall formwork is fixed by the three-jaw clamping support formed by one triangular support plate and two support tooth plates, this support has very high stability, avoid in concrete pouring and vibrating under guide wall formwork possibly move deflection, the case of influence wall surface flatness, and because top block extrudes and fixes the upper end of guide wall formwork, avoid the possibility that guide wall formwork occurs angular deviation, ensure the quality of guide wall, simultaneously because device and guide wall formwork are extruded contact support so as to only need to separate support component from guide wall formwork, quick dismounting effect can be realized.
