AI Technical Summary

Technical Problem

The traditional storage tank anchoring structure uses a single bolt to penetrate the multi-layer board to fix it, resulting in non-uniform load distribution under low-temperature cold shrinkage and liquid cargo swaying, resulting in mechanical stability failure and increasing the risk of cracking of the main shielding film.

Method used

The polyurethane plate is fitted with the insulating box plywood, the anchor connecting plate is fixed by rivets, and the intermediate connecting body assembly is screwed into the assembly screw groove for pre-positioning and assembly, and a seal is formed by lap welding. The intermediate connecting assembly is adjusted to flush through a fuse processing or a fine-tuning mechanism to ensure the sealing and positioning accuracy of the multi-layer board.

Benefits of technology

It effectively solves the displacement problem caused by single-point fixation, avoids fixation failure caused by cracking of stepped holes and different material shrinkage coefficients, and improves the sealing and mechanical stability of the storage tank structure.

Abstract

The embodiment of the invention provides a plywood anchoring method and structure, and relates to the technical field of plywood anchoring. The plywood anchoring method comprises the following steps that S1, a polyurethane plate body is arranged above a lower plywood of an insulation box, the polyurethane plate body is aligned with an embedding hole of an upper plywood of the insulation box, an anchoring plate is embedded and installed in the embedding hole, and an anchoring connecting plate is fixed to the surface of the upper plywood of the insulation box through rivets; and S2, the middle connector assembly is screwed into an assembly screw groove formed in the surface of the anchoring plate for pre-positioning assembly. According to the scheme, the problem of displacement caused by single-point fixation is avoided by limiting and fixing the multiple layers of plates, and the situation that the steps in the stepped holes crack and fixation fails due to different shrinkage coefficients of different materials is avoided due to the through hole design of the multiple layers of plates in the fixing mode.
