Waterproof joint for external wall panel

Abstract

The invention belongs to the field of building structures and in particular discloses a waterproof joint for an external wall panel. The waterproof joint for the external wall panel comprises an upper external wall panel and a lower external wall panel, wherein the upper external wall panel and the lower external wall panel at least comprise an insulating layer and a structural layer, a waterproof piece is arranged between the upper external wall panel and the lower external wall panel, a water guiding board is arranged at the bottom of the insulating layer of the upper external wall panel, one side of the water guiding board is anchored in the structural layer of the upper external wall panel, and the other side of the water guiding board is extended to the outer side of the waterproof piece. The waterproof joint for the external wall panel has the advantages that outdoor rainwater is effectively prevented from leaking into interior along a seam line, so that a reliable waterproof guarantee is provided; besides, when the rainwater enters the insulating layer of the lower external wall panel, flows downward along the insulating layer and flows to the next joint below the joint, the water guiding board guides the rainwater to the outer side of the waterproof piece as the water guiding board is arranged at the bottom of the insulating layer. The waterproof joint for the external wall panel combines waterproofing with water guiding, water can be prevented from leaking into the interior, and the water also can be effectively guided out to the outside and is not deposited in an external wall.

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 ...

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 is reduced, which brings 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 water leakage and affect the waterproof performance of the prefabricated building. and build quality
