AI Technical Summary

Technical Problem

Existing curtain wall buildings' drainage pipes generate noise when dripping intermittently or continuously, affecting the user experience. In cold environments, they are prone to freezing, which can damage the equipment and reduce the practicality of the drainage system.

Method used

A concealed drainage pipe structure including a water collection tank and a gravity valve was designed. The water collection tank collects accumulated water and automatically discharges it through the gravity valve when a certain amount is reached. Combined with components such as a filter screen, insulation layer, heating element and temperature sensor, the stable operation of the drainage system is ensured.

Benefits of technology

It effectively reduces the noise from frequent dripping of the drain pipe, improves the user experience, maintains the stability of the drainage function in cold environments, and reduces maintenance costs and the risk of equipment damage.

Abstract

The utility model provides a drain pipe concealed burying structure applied to a curtain wall building, and relates to the technical field of building construction. The drain pipe concealed burying structure comprises a curtain wall and a building structure wall body, a mounting space is formed between the bottom of the curtain wall and the outer side face of the building structure wall body, and a drain grating is arranged at the bottom of the curtain wall; the water collecting pipe is arranged on the inner side of the building structure wall, one end of the water draining pipe is communicated with the water collecting pipe, and the other end of the water draining pipe penetrates through the building structure wall, extends to the installation space and is communicated with the water collecting tank located in the installation space; wherein the water collecting tank is located below the drainage pipe, a drainage port is formed in the bottom of the water collecting tank, and a gravity valve is arranged at the drainage port. According to the drain pipe concealed burying structure, intermittent or continuous drained water is treated in a centralized mode through the arrangement of the water collecting tank and the gravity valve, the situation that the drain pipe directly and frequently drains water or drips water is reduced, and noise generated by the situation is effectively reduced.
