Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a top pressing system of an assembled prefabricated external wall panel. Background Art

[0002] Prefabricated external wall panels are different from traditional PC components. They are made of plain concrete with a regular surface, bright and clean, uniform color, and beautiful appearance. They have functions such as enclosure, fire prevention, heat preservation, thermal insulation, sound insulation, and decoration. The prefabricated external wall panels are connected to the embedded parts of the main structure through 2 bolt connection nodes + 4 angle steel connection nodes, which greatly reduces the difficulty of on-site construction. However, since there is a 50mm gap between the prefabricated external wall panels and the main structure, and in order to ensure the appearance of the external wall panels, the roof waterproofing can only be constructed to the top of the external wall panels, and cannot be extended to the facade of the external wall panels for closing, so there is a greater risk of leakage. In order to solve the above problems, the present invention designs a top-pressing system for prefabricated external wall panels, which can effectively solve the risk of leakage and can be perfectly integrated with the roof. Utility Model Content

[0004] The utility model achieves the above technical objectives through the following technical means.

[0005] A prefabricated assembled external wall panel top pressure system includes rock wool filled in the gap between the external wall panel and the main structure, the top of the rock wool is sealed with fireproof sealant, the waterproof layer of the external wall panel adopts a layer of non-curing asphalt waterproof coating and a layer of self-adhesive polymer modified asphalt waterproof membrane, the roof waterproof layer extends from the roof to the top of the external wall panel, ends at a distance from the external facade of the external wall panel, and is fixed with waterproof metal strips; multiple cover plates are arranged on the top of the waterproof layer, the cover plates are reversely sloped inwardly toward the roof, the cover plates are supported and reinforced by L-shaped partitions arranged at intervals, and adjacent cover plates are sealed at the L partition positions on the adjacent edges by foam rods and sealant; the ends of the cover plates are respectively fixed to the top of the external wall panel and the roof structure plate by waterproof sealing nails.

[0006] Furthermore, the filling depth of the fireproof sealant filled on the top of the rock wool is not less than 25 mm, and the fire resistance limit of the fireproof sealant is not less than the fire resistance time of the rock wool.

[0007] Furthermore, the waterproof layer is reinforced with a waterproof roll material reinforcement layer at the gap between the external wall panel and the main structure, and a foam rod with a diameter of 20 mm is padded at the bottom to reserve waterproof deformation.

[0008] Furthermore, the waterproof layer of the exterior wall panel adopts a layer of 2.0 mm thick non-curing asphalt waterproof coating and a layer of 3.0 mm thick self-adhesive polymer modified asphalt waterproof membrane.

[0009] Furthermore, the upper part of the waterproof layer uses multiple 1.5mm thick and 2m long aluminum panels as cover plates, and the cover plates use a shedding board structure on the exterior facade of the external wall panels to prevent rainwater from seeping in from the end of the waterproof layer. The shedding board of the cover plate is laid close to the exterior facade of the external wall panels.

[0010] Furthermore, the L-shaped partitions are arranged at intervals of 1 m.

[0011] Furthermore, the L-shaped partition is cut off with a gap at the gap between the external wall panel and the main structure to avoid damaging the waterproof effect of the relevant part.

[0012] Furthermore, the waterproof sealing nail is sealed with waterproof glue.

[0013] Furthermore, the roof is paved with tiles, which are laid to a position 20 mm wide from the edge of the cover plate. The surface of the tiles is lower than the cover plate and slopes inwardly toward the structure. The 20 mm wide gap between the cover plate and the roof tiles is filled tightly with foam rods and waterproof sealant.

[0014] Furthermore, the cover plate is connected to the roof lightning strip grid.

[0015] The utility model has the following beneficial effects:

[0016] This utility model is an easy-to-install assembled prefabricated external wall panel top pressure structure, which can form the assembled prefabricated external wall panel and the roof waterproof system into a whole, effectively improving the waterproof and sealing effect of the joints between the roof and the wall panel. Its top aluminum single plate pressure can also be effectively combined with the roof lightning protection system to achieve a certain lightning protection effect; and the top pressure system of the assembled prefabricated external wall panel combines the external wall panel with the roof surface layer, improving the integrity and aesthetics of the building.

This simple process and convenient installation effectively improve the installation efficiency of prefabricated exterior wall panels. The aluminum cover can be sprayed with fluorocarbon paint that matches the exterior wall panel color, enhancing the appearance. BRIEF DESCRIPTION OF THE DRAWINGS
