Waterproof joint structure of steel structure workshop

Abstract

The invention relates to a waterproof joint structure of a steel structure workshop. The waterproof joint structure comprises a flashing structure in the side span position. The flashing structure at least comprises angle covering plates provided with a flashing part and at least one fixed part. Lowest point water dropping levels extending downward are arranged on the flashing parts, the fixed parts are fixed to a wall body through a fixing mechanism. The positions, provided with gaps with a water seepage wall body, on the angle covering plates are bonded through sealing glue. According to the joint structure, the flashing problems of joints such as high and low spans and inner gutters are better solved, compared with a leakage-proof structure of the prior art, the waterproof joint structure is more reasonable and better in effect.

Description

technical field [0001] The invention relates to the field of industrial buildings, in particular to a waterproof node structure at the vertical and horizontal spans of a steel structure factory building. Background technique [0002] In industrial buildings, with the wide application of steel structures, the shape of steel structures has become more and more diversified from the original "rectangular block", and there are more and more crisscross forms. At the same time, the diversified designs also bring Come a lot of questions. The joint structure involves deformation joints, inner gutters, and high and low spans. At the same time, the joints involve a wide range and complex structures. If they are not handled properly, they will leave great hidden dangers for the future; Relying on the national standard atlas is far from meeting the design requirements. It is necessary to develop such a comprehensive node structure to facilitate similar projects in the future. [0003] ...

AI Technical Summary

Problems solved by technology

However, the steel structure factory building product does not have an insulation layer, and the factory building is easily affected by the external temperature, resulting in a poor environment for internal personnel and easy damage to mechanical equipment; there is no disclosure in the prior art about how to install an insulation layer and rainwater protection in the inner gutter. Leakage combined technical solution

In addition, most of the flashing boards in the prior art are close to the wall structure. The bottom or inward fold of the flashing board is suspended in the air or is directly attached to the corresponding wall. There is no sealing structure, which leads to poor flashing effect, especially when rainwater is excessive. For a long time, the flashing board is prone to water seepage along the inward folded part or the gap between it and the wall due to excessive water volume, resulting in hidden dangers of water leakage
