Description

A waterproof prefabricated wall panel with connectors

technical field

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

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 connectors. The utility model integrates energy saving, environmental protection and heat preservation, and can effectively prevent the phenomenon of water accumulation and internal seepage in the sandwich panel of the existing external wall. .

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

A waterproof prefabricated wallboard with connectors, comprising two structural layers and a polystyrene foam board layer, the polystyrene foam board layer is glued between the two structural layers to form a sandwich wall, The left and right ends of the two structural layers extend outward and protrude from the end faces of the polystyrene foam board layer. The left and right end faces of the two structural layers are bonded with U-shaped waterproof boards with sealant. The bottom edge of the U-shaped waterproof board is located The surface of the board completely covers the end faces of the left and right sides of the polystyrene foam board layer. The end faces of the two sides of the U-shaped waterproof board extend outward along the inner sides of the two structural layers, and the end of the U-shaped waterproof board is inserted into the structure vertically. In the layer, there are L-shaped connectors on the end faces of the upper and lower sides of 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.

Furthermore, positioning screws are provided on the protruding end connecting the U-shaped waterproof board and the structural layer of the utility model.

Furthermore, the extended length of the protruding end of the U-shaped waterproof board described in the present invention is not less than 5cm.

Furthermore, a connecting hole is provided on the connecting end of the protruding part of the L-shaped connector of the present invention.

The beneficial effects of the utility model are as follows: 1. In the utility model, the end faces of the left and right sides of the polystyrene foam board layer are covered with U-shaped waterproof boards respectively, and the ends of the extended parts of the U-shaped waterproof boards are vertically inserted into the structure In the layer, the possibility of rainwater infiltrating from the gap between the structural layer and the polystyrene foam board layer is fundamentally blocked, and the damage of rainwater to the insulation layer is avoided. 2. The utility model is also equipped with L-shaped connectors on the structural layer, which greatly facilitates the butt joint between the walls. 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 description

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

As shown in Figure 1, a waterproof prefabricated wallboard with connectors includes two structural layers 1 and a polystyrene foam board layer 2, and the polystyrene foam board layer 2 is bonded to the two structural layers by glue A sandwich-shaped wall is formed between 1, the left and right ends of the two structural layers 1 extend outwards and protrude from the end faces of the polystyrene foam board layer 2, and the left and right end faces of the two structural layers are bonded by sealant 7 There is a U-shaped waterproof board 3, the board surface where the bottom edge of the U-shaped waterproof board 3 is located completely covers the end faces on the left and right sides of the polystyrene foam board layer 2, and the end faces where the two sides of the U-shaped waterproof board 3 are located are along the two structural layers. The inner side of 1 extends outward, the length of the protruding end of the U-shaped waterproof board 3 extending outward is not less than 5cm, and the protruding end of the U-shaped waterproof board 3 connected to the structural layer 1 is provided with a positioning screw 5, and the U-shaped waterproof The end of the extended end of the plate 3 is vertically inserted into the structural layer, and an L-shaped connector 4 is also provided on the end faces of the upper and lower sides of the two structural layers 1, and one end of the L-shaped connector 4 extends into the structural layer 1. In addition, One end protrudes out of the structural layer 1, and a connection hole 6 is provided on the connection end of the protruding part of the L-shaped connector.

When in use, as shown in Figure 2, the prefabricated wallboard of the present utility model is butted with the adjacent prefabricated wallboard by using the connector 4, and the fasteners such as expansion bolts, screws or self-tapping screws pass through the connection holes to fix the connection. The end faces of the left and right sides of the styrene foam board layer are respectively covered with U-shaped waterproof boards, and the ends of the extended parts of the U-shaped waterproof boards are vertically inserted into the structural layer, fundamentally blocking the rainwater from the structural layer and polystyrene. The possibility of infiltration in the gaps of the vinyl foam board layer avoids the damage of rainwater to the insulation layer; the L-shaped connector set on the structural layer greatly facilitates the butt joint between the walls.
