A prefabricated building external wall panel drainage structure

Abstract

This application relates to a drainage structure for externally hung wallboards in a prefabricated building, which includes a wall body, the wall body includes horizontal plates and vertical plates, a cavity is provided inside the wall body, the cavity is slidably connected with a drainage board, and the wall body is provided with drainage holes , the outer wall of the longitudinal plate is fixedly connected with a motor, the inner wall of the longitudinal plate is fixedly connected with a disk, the output shaft of the motor is connected with a connecting rod, the connecting rod is hinged with a slider one, the rotating disk is connected with a ring, and the ring is fixed with a strip plate , the strip plate is provided with a strip groove 1, the slider 1 is slidably connected in the strip groove 1, the slider 1 is hinged to the slider 2, the drain plate is provided with a strip groove 2, and the slider 2 is slidably connected to the strip groove two inside. The motor drives the connecting rod to rotate, so that slider 1 slides in the bar groove 1, and then rotates around the disc, so that slider 2 rotates, and then the drain plate slides up and down in the cavity, and the drain plate moves up and down to the lower end of the cavity. Squeeze the stagnant water inside, accelerate the stagnant water flow from the drainage hole to the outside of the wall, and quickly and effectively discharge the stagnant water in the cavity.

Description

technical field [0001] The present application relates to the field of construction engineering, in particular to a drainage structure for externally hung wallboards of prefabricated buildings. Background technique [0002] Prefabricated buildings refer to the structural bodies of buildings (such as wall panels, columns, beams, floors, stairs, etc.) that are disassembled according to certain specifications and then prefabricated in the factory, and then transported to the site for assembly. As a part of the external enclosure structure of the prefabricated building, the horizontal and vertical connections at the assembly point are generally handled by gluing. For the sake of saving materials, sound insulation, and heat insulation, most of the interior of the external wall panels A cavity is left. [0003] During production, after the external wall panels are disassembled according to certain specifications, they are prefabricated in the factory, and then transported to the ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that there is a certain height difference between the pipe column and the pipe seat in the above-mentioned drainage structure, but when the rainfall time is long, the surface runoff is large, and the rainwater accumulation is large, the use effect of this structure is not good. Good, the water in the cavity of the external wall panel cannot be completely drained, the drainage structure is closed for a long time, it is easy to make the external wall panel in a humid environment for a long time, and the problem of water accumulation in the cavity inside the wall panel cannot be solved quickly and effectively. It will be moldy and cracked under long-term rainwater immersion, which will have a negative impact on the performance of the prefabricated building's external wall panels
