Description

A waterproof prefabricated wall panel with interconnected embedded parts

technical field

The utility model relates to a prefabricated wallboard, in particular to a waterproof prefabricated wallboard with interconnected prefabricated parts.

Background technique

The development of science and technology and the progress of society, while bringing convenience to people's lives, have also brought about various problems such as temperature rise, environmental pollution, noise pollution, and frequent fires. Faced with this series of problems, people have more and more demands on buildings for work and living, such as: heat insulation, sound insulation, fire prevention, waterproof, anticorrosion, insect prevention, etc. At present, most of the buildings in our country have brick wall structures, and the traditional building wall structures have poor sound insulation and heat insulation effects, which cannot meet the needs of the current construction field.

It is in this situation that composite wall panels come into being. The common composite wallboard is to use brick wall or reinforced concrete as the load-bearing structural wall, and compound it with thermal insulation materials; the second is to use steel or reinforced concrete as the frame structure, and use thin-walled materials to sandwich thermal insulation materials as the wall. Common forms of composite wall panels include internal thermal insulation composite wall panels, external thermal insulation composite wall panels, and concrete sandwich wall panels. Composite wall panels are generally prepared in blocks, and they are docked according to the needs of the space used during use. Compared with the traditional block enclosure or cement on-site pouring enclosure, the prefabricated wall panel saves the process and improves the construction speed. However, in the process of assembling the wall with wall panels, after the superimposed installation of the intermediate interlayer construction, a transverse gap will be formed between the upper and lower structural layers. Usually, waterproof glue or plaster is used to close the gap between the upper and lower structural layers. When the building faces washing or heavy rain, water is easy to soak into the transverse gap between the two structural layers, and it is difficult to recover from dryness. Water infiltration often occurs in the sandwich panels of the exterior walls, which affects the quality and service life of the building.

Contents of the invention

In view of the above technical problems, the utility model provides a waterproof prefabricated wall panel with interconnected embedded parts. Effectively prevent the occurrence of water accumulation and internal seepage in the sandwich panel of the external wall.

In order to achieve the above-mentioned technical purpose, the utility model adopts the following scheme:

A waterproof prefabricated wall panel with interconnected embedded parts, comprising two structural layers and a polystyrene foam board layer, the polystyrene foam board layer is bonded between the two structural layers to form a sandwich The wall also includes reinforcing ribs, L-shaped connectors and U-shaped waterproof boards, the waterproof boards are covered at the end faces of the left and right sides of the polystyrene foam board layer, and the two sides of the waterproof boards extend inward and are embedded Between the structural layer and the polystyrene foam board layer, there are L-shaped connectors on the two structural layers. One end of the L-shaped connector extends into the structural layer, and the other end extends out of the structural layer. The two structural layers are opposite to each other. The two L-shaped connectors are connected to each other through reinforcing ribs, and the reinforcing ribs vertically penetrate the two sides of the waterproof board.

Further, the L-shaped connectors described in the present invention correspond one-to-one to the left and right, and the arrays are distributed on the left and right sides of the structural layer.

Further, two groups of through holes are provided on the end surface of the extended part of the L-shaped connector described in the utility model, and each group of three through holes is arranged, and the three through holes in each group are evenly distributed in the equilateral triangle. on the three vertices.

Furthermore, the cross-section of the reinforcing rib in the present invention is circular.

Furthermore, the protruding end of the U-shaped waterproof board of the present invention extends inward and is embedded in a length of not less than 8cm.

The beneficial effects of the utility model are as follows: 1. The utility model is coated with H-shaped waterproof boards on the left and right end faces of the polystyrene foam board layer, and the H-shaped waterproof boards directly prevent rainwater and polystyrene The contact between the end faces of the two sides of the foam board layer; on the other hand, the H-shaped waterproof board extending outward not only balances the force of the intrusion and extension end, but also can further prevent the rainwater from the gap between the structural layer and the interlayer on the prefabricated wall. Infiltration of the board. 2. The L-shaped connectors between the two structural layers of the utility model are connected to each other through the reinforcing ribs. The reinforcing ribs not only penetrate the two sides of the U-shaped waterproof board, but also penetrate between the three layers, so that the two can be connected. The parts are effectively held in the three-layer wall structure, and the connecting parts are not easy to fall off after the walls are butted. 3. The addition of polystyrene foam board layer makes the prefabricated wall panel integrate energy saving, environmental protection and heat preservation, and effectively realize the functions of energy saving, environmental protection and heat insulation of the composite wall.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2 and Figure 3, a waterproof prefabricated wall panel with interconnected embedded parts includes two structural layers 1 and a polystyrene foam board layer 2, and the polystyrene foam board layer 2 A sandwich-shaped wall is formed between the two structural layers 1 through glue bonding, and also includes reinforcing ribs 3, L-shaped connectors 4 and U-shaped waterproof boards 5, and the waterproof boards 5 are covered with polystyrene At the ends of the left and right sides of the foam board layer 2, the two sides of the waterproof board 5 extend inward and are embedded between the structural layer 1 and the polystyrene foam board layer 2, and the protruding end of the U-shaped waterproof board extends inward and is embedded. The length is not less than 8cm; the two structural layers 1 are oppositely provided with L-shaped connectors 4, one end of the L-shaped connectors 4 extends into the structural layer 1, and the other end extends out of the structural layer 1, and the left and right L-shaped connectors correspond one by one , the array is distributed on the left and right sides of the structural layer, the two L-shaped connectors 4 facing each other between the structural layers are connected to each other through the reinforcing rib 3, and the cross section of the reinforcing rib is circular, and the reinforcing rib 3 vertically penetrates the waterproof The two sides of the board protrude. In order to facilitate the docking between the walls, two groups of through holes are provided on the end surface of the protruding part of the L-shaped connector described in the utility model.
