Outer wall plate waterproof node

Abstract

The invention belongs to the field of construction structures, and in particular discloses an outer wall plate waterproof node which comprises an upper outer wall plate and a lower outer wall plate, wherein the upper outer wall plate and the lower outer wall plate at least comprise an outer plate, a heat-preservation layer and a structural layer; the heat-preservation layer is arranged between the outer plate and the structural layer; a notch is formed in the upper outer wall plate; a waterproof plate is arranged between the upper outer wall plate and the lower outer wall plate; one side of the waterproof plate is arranged between the heat-preservation layer of the lower outer wall plate and the outer plate, and the other side of the waterproof plate extends into the notch; and at least a part of the waterproof plate extends into the notch. According to the outer wall plate waterproof node disclosed by the invention, the waterproof plate is simple and convenient to arrange, no groove and tongue or other waterproof structure is needed in the prefabrication process of the outer wall plates, molds can be simplified, meanwhile convenience is brought to transportation of the outer wall plates, the situation that waterproof components are damaged in the transportation process can be avoided, and the production efficiency and construction quality of an assembled building can be increased.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a waterproof node of an exterior wall board. Background technique [0002] In the prefabricated construction industry, the exterior wall panels are manufactured in a prefabricated manner, and then assembled on site, so that standardization can be achieved, and the quality is controllable, efficient and fast. However, during the on-site assembly of prefabricated exterior wall panels, waterproof treatment should be carried out at the joints to prevent rainwater from seeping into the room along the joints of the exterior wall panels. The effective bearing capacity of the external wall decreased, which brought major engineering hidden dangers. The waterproofing of traditional external wall panels is usually to apply waterproof glue at the joints. Not only the construction workload is heavy, but also the waterproof glue will age over time, which will eventually lead to ...

AI Technical Summary

Problems solved by technology

However, after installing waterproof grooves on the outer wall panels, on the one hand, it is not conducive to the transportation of the inner partitions of the outer walls, and it is very easy to cause damage to the waterproof grooves during transportation or construction, and this method is not suitable for external wall insulation Assembling boards and decorative panels, for external wall insulation panels, it is easy to damage the insulating layer as a part of the tongue and groove during the butt joint process, thereby affecting the waterproof effect. , the decorative surface at the end of the decorative panel is split, it is easy to be damaged during transportation and docking, and it is difficult to repair, which seriously affects the appearance
