AI Technical Summary
Technical Problem
The existing connection method at the cross intersection of waterstop steel plates is prone to misalignment, resulting in low installation accuracy, material waste, and difficulty in adjusting the angle.
Method used
The structure consists of an upper cover plate and a lower cover plate. It is initially fixed by wing plates and bolts. After adjusting the angle of the water-stop steel plate, it is welded. A sealing strip is installed at the joint to ensure accuracy and waterproof effect.
Benefits of technology
It improves the positional accuracy of the waterstop steel plate connection, avoids misalignment, saves manpower, provides flexibility in angle adjustment, and provides additional waterproof protection after welding.

Abstract
This invention discloses a method for connecting water-stop steel plates at a cross intersection. The method includes the following steps: S1, fabricating an upper cover plate and a lower cover plate; S2, fixing outwardly extending wing plates to the side plates at all four ends of the upper and lower cover plates; S3, creating grooves at the four ends of the bottom plates of the upper and lower cover plates; S4, installing sealing strips in the grooves; S5, attaching the ends of the four water-stop steel plates to be connected to the lower cover plate, and then attaching the upper cover plate to the water-stop steel plates; S6, initially fixing the wing plates of the upper and lower cover plates with bolts; S7, adjusting the angles of the four water-stop steel plates and further tightening the bolts; S8, welding the overlap between the upper cover plate and the water-stop steel plates; S9, disassembling the lower cover plate and welding the other side of the overlap between the water-stop steel plates and the upper cover plate to achieve a full weld. This invention prevents the upper and lower cover plates from shifting during the welding process of the water-stop steel plates, ensuring the positional and installation accuracy of the water-stop steel plate connection and saving manpower.
