The object of the present invention is to provide a precast panel for construction which enhances anti-aging and anti-damage properties during long-term use, and extends the life span and stability during long-term use.

In order to achieve the purpose, the utility model adopts the technical scheme that: a prefabricated plate for building is composed of a main body made of foam material and with two opposite end faces, a longitudinal boss on one end face and a longitudinal recess on another end face, and a panel layer attached to both surfaces of said main body.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, a plurality of strip-shaped holes arranged at intervals are formed in the body, and at least one end of each strip-shaped hole is communicated with the outside of the body.

2. In the scheme, the strip-shaped holes are arranged in parallel at intervals.

3. In the above scheme, two ends of the strip-shaped hole respectively penetrate through two opposite end faces of the body.

4. In the above scheme, two opposite end faces of the body are respectively provided with a strip-shaped groove portion arranged along the length direction.

5. In the above scheme, the foaming material is foamed polypropylene, foamed polyurethane or foamed polystyrene.

6. In the scheme, the panel layer is a cement fiber board layer, a gypsum board layer or a wood board layer.

7. In the scheme, the panel layer is bonded with the body through glue.

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

1. the prefabricated plate for the building can be used as a wallboard, a bottom surface or a roof panel, greatly reduces the weight, is convenient to transport, assemble and disassemble, is easy to assemble, enhances the waterproof and heat-insulating performance, saves energy and protects environment when compared with other plates with the same area; furthermore, the surfaces of the two sides of the body are respectively attached with a panel layer, so that the ageing resistance and the damage resistance in the long-term use process are enhanced, and the service life and the stability in the long-term use process are prolonged.

2. According to the prefabricated slab for the building, the plurality of strip-shaped holes which are arranged at intervals are formed in the body, at least one end of each strip-shaped hole is communicated with the outside of the body, and the arrangement of the strip-shaped holes enables the inside of the body to form the cavity, so that the cost is saved, and the overall heat insulation performance is enhanced; in addition, a strip-shaped groove part arranged along the length direction is formed on the other two opposite end faces of the body, so that a supporting metal part is convenient to additionally install between the groove parts of the adjacent bodies, and the structural stability of the joint is ensured while the connection between the adjacent bodies is realized.
