AI Technical Summary

Technical Problem

Existing precast steel plate corner supports have poor flexibility in deep foundation pit projects, making it difficult to adjust quickly according to changes in the foundation pit and affecting work efficiency.

Method used

A precast steel plate corner bracing device for the internal corner support of deep foundation pit engineering was designed. By setting grooves and adjusting plates on the protective plate, the adjusting plate can be flexibly adjusted using components such as screws, moving seats, locking parts, sliding grooves and elastic parts, thereby enhancing the connection strength and stability.

Benefits of technology

It enables rapid position adjustment of the adjustment plate on the protective plate, improving the flexibility and ease of operation of the device, saving time for re-customization, enhancing connection strength and stability, and improving work efficiency.

Abstract

This utility model relates to the field of engineering construction technology, specifically disclosing a precast steel plate corner bracing device for deep foundation pit engineering, including a protective plate and an adjusting plate. A groove is formed on one side of the protective plate, and a lead screw is horizontally connected inside the groove. A movable seat is connected to the lead screw, and a locking element is horizontally arranged on the movable seat. One end of the adjusting plate is disposed inside the groove, and several sliding grooves are formed on one side of the adjusting plate. Each sliding groove is connected to an elastic component, and a slider is connected to one end of each elastic component. The slider is slidably connected to the sliding groove, and the end of the slider away from the sliding groove extends into the groove. Grooves are formed on both sides of the adjusting plate, and these grooves communicate with the sliding grooves. Limiting blocks are provided inside the grooves, and one end of each limiting block is fixed to the side of the slider. A sleeve rod is rotatably connected to the end of the limiting block away from the slider. Several fixing blocks are fixed to the side of the adjusting plate.
