Description

External wall foam insulation board

The utility model relates to a foam insulation board for the outer wall of a building.

There are a variety of technical structures and products for building wall insulation, one of which is to paste foam insulation boards on the inside and outside of the wall. At present, foam insulation boards used for building exterior wall insulation also have various structural forms, the simplest The best is a simple foam board without a composite layer, or some holes or concave-convex platforms are opened on the foam board surface to facilitate pasting with the wall. When pasting, apply cement mortar to the foam board surface during on-site operations. Then it is pasted with the cement wall, and the outer surface of the foam board is coated with a cement mortar surface layer and a decorative surface layer. In the prior art, there is also an external wall foam insulation board that is coated with cement mortar layer in advance on one side or the front and back of the foam board. However, due to the limitations of the structure of the foam insulation boards in the prior art, most of them have slow construction speed on site, great difficulty, deflection of the board surface, cracks and water seepage on the cement surface of the board joints, resulting in problems such as delamination and falling off.

The purpose of the utility model is to provide a kind of external wall foam insulation board composed of composite prefabrication of multi-layer materials, which is convenient in construction and use, and has good performance in use.

The technical solution of the present utility model is that inclined surfaces 10, 10' are provided on both sides of the foam board 1, and stoppers 20, 20' that overlap and cooperate with each other are respectively provided on the two sides. A cement mortar layer 2, a glass fiber mesh layer 3, a cement mortar layer 4, and a waterproof decorative paint surface layer 5 are sequentially compounded on the outer surface of the foam board 1, and a cement mortar layer 6, glass The fiber mesh layer 7 and the surface sand grain layer 8 are formed.

The utility model is prefabricated, processed and manufactured in a factory, and can be pasted directly on the spot when used, and the construction is convenient. The cement glue mortar layer on the inner and outer surfaces of the foam board 1 and the fiberglass net layer can effectively prevent the deflection of the board surface, and the strength of the foam board is high. The foam board 1 is overlapped up and down, and colored elastic glue is smeared on the inclined surfaces 10 and 10 of the butt joints to form the slope angle recesses, which can not only ensure that the seams are not seepage, deformation, and cracks, but also have a beautiful appearance.

Accompanying drawing is the structural representation of the utility model.

Referring to the accompanying drawings, the utility model consists of a polystyrene foam board 1, which is provided with inclined surfaces 10, 10' at both ends of the polystyrene foam board 1, and has upper and lower sides respectively at both ends of the polystyrene foam board 1. The joints 20 and 20' that are overlapped with each other are sequentially compounded with a cement mortar layer 2, an alkali-resistant glass fiber mesh layer 3, a cement mortar layer 4, and a waterproof decorative paint surface on the outer surface of the polystyrene foam board 1. Layer 5 is composed of cement mortar layer 6, glass fiber mesh layer 7 and surface sand grain layer 8 sequentially compounded on the inner surface of polystyrene foam board 1. The cement mortar layer 2, 4, 6 is the cement layer formed by mixing cement and sand with the glue, the glue used is not limited, it can be various glues used in the prior art, Such as acrylic glue. The utility model is multi-layer composite, when the cement glue mortar layer is wet and not dry, the glass fiber mesh layer is attached, and the sand grain layer 8 sticks on the glass fiber mesh layer and penetrates or penetrates on the cement glue mortar of the glass fiber mesh.
