External wall panel installation node

Abstract

The invention belongs to the field of building structures and discloses an external wall panel installation node comprising an upper external wall panel, a lower external wall panel, a crossbeam, and connectors used for fixing the upper external wall panel. The connectors include a connecting plate and an anchoring part, a limit part is arranged on the upper portion of the connecting plate, the anchoring part is located on the lower portion of the connecting plate and connected with the connecting plate, the upper end of the crossbeam is provided with a cast-in-place layer, the anchoring part is anchored in the cast-in-place layer, and the limit part is inserted into the upper external wall panel from the bottom end of the upper external wall panel; each of the upper external wall panel and the lower external wall panel at least comprises an insulation layer and a structural layer, a waterproof part is arranged between the upper external wall panel and the lower external wall panel, the bottom of the insulation layer of the upper external wall panel is provided with a water conduction board, one side of the water conduction board is anchored in the structural layer of the upper external wall panel, and the other side extends to the outer side of the waterproof part. Water proofing and water conduction are combined, defects of the conventional external panel installation mode are overcome, and the external wall panel installation node is firm in connection and convenient to install.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to an exterior wall board installation node. 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. At present, in the installation process of exterior wall panels, there are usually two methods, one is wet-hanging connection, the upper part of the connecting steel bar pre-buried in the exterior wall panel is extended into the cast-in-place layer on the upper part of the composite beam, and the cast-in-place concrete is fixed Connection, this simple method of connecting with steel bars is not stable, and it is easy to produce errors and offsets during the concrete construction process, and it is not easy to correct in the later installation; The anchor bar or st...

Problems solved by technology

At present, in the installation process of exterior wall panels, there are usually two methods, one is wet-hanging connection, the upper part of the connecting steel bar pre-buried in the exterior wall panel is extended into the cast-in-place layer on the upper part of the composite beam, and the cast-in-place concrete is fixed Connection, this simple method of connecting with steel bars is not stable, and it is easy to produce errors and offsets during the concrete construction process, and it is not easy to correct in the later installation; The anchor bar or steel plate connector, the anchor bar or steel plate connector is rigidly connected to another embedded part embedded in the frame beam through the angle steel. This method has a relatively short construction period, but it is inconvenient to install. Parts are pre-embedded according to the predetermined spacing, and the design size is required to be very precise, otherwise it will be difficult to connect successfully. Once the connection fails, it will not only take time and labor, but even cause the external wall panels to fail to connect, resulting in waste

[0003] At the same time, 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
