Abstract

The invention discloses a steel bar welding and fixing device for a foundation pit support. The steel bar welding and fixing device comprises a protective frame. Support beams are arranged inside theprotective frame from top to bottom in sequence. Steel bars are connected between the support beams in a penetration mode. Reinforcing plates are welded to the front sides of the steel bars. The two ends of each reinforcing plate extend to the front side of the protective frame. The end, located on the front side of the protective frame, of each reinforcing plate is fixedly provided with clampingblocks. According to the steel bar welding and fixing device for the foundation pit support, fastening sleeves are arranged at the upper end of the protective frame in a sleeving mode and are fixed through fixing bolts to ensure that the fastening sleeves are mounted on the surface and cannot slide; the support beams are welded to the side faces of the fastening sleeves, and the upper and lower ends of the steel bars penetrate into the support beams to ensure that the steel bars and the support beams cannot shake after being connected; the reinforcing plates are welded to the front sides of the steel bars, the clamping blocks at the two ends are clamped into the protective frame and can connect and fix the steel bars; and the protection strength and the safety coefficient of the foundationpit support are enhanced, and the steel bar welding and fixing device ensures that no shaking and fracture can occur.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a steel bar welding and fixing device for foundation pit support. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The rod is inserted into the side wall of the foundation pit, and then concrete is injected to fix the anchor rod and the side wall of the foundation pit, and then steel bars are embedded in the excavated foundation pit to fix the steel bar and the anchor rod, and then another steel bar is fixed with an iron wire. It is connected with the steel bars buried in the foundation pit, and the foundation pit support is built by connecting multiple steel bars horizontally and vertically; however, the production efficiency of this steel bar connection method is relatively low, and the strength of the steel bars is not enough after the...
