Embodiment 1

[0041] An assembled self-insulating metal decorative exterior wall panel with a thickness of 200mm, including a wall 7 composed of lightweight high-specific-strength high-porosity concrete 5, an insulation layer 4 and light-weight high-specific-strength low-porosity concrete 3, and is arranged on the wall 7. The metal shell 6 on the outside, the metal shell 6 adopts galvanized steel plate with decorative effect, and adopts a triangular push-in connection device.

[0042] The lightweight, high-specific-strength, high-porosity concrete layer 5 in the wall 7 has a thickness of 50mm and a dry density of 800kg / m 3 About, thermal conductivity 0.15W / (m 2 About K), the solid cube is made of light aggregate porous concrete with a compressive strength of about 7.5MPa; the formula of the material used is: P.II 42.5 cement 280kg / m 3 , ceramic hollow microspheres 70kg / m 3 , yellow sand 100kg / m 3 , light coarse aggregate of density grade 700 400kg / m 3 , tap water 105kg / m 3 , mixed foam...

Abstract

The invention discloses an assembled self-insulating metal decorative exterior wall panel, which comprises a metal shell and a wall, the metal shell constitutes the outer surface of the exterior wall panel, and the wall is poured into the metal shell. After hardening, the two are combined to form an overall exterior wall panel; the metal shell is in a groove-shaped semi-enclosed structure, and the edge of the notch is folded inward at 90°, and its length is equal to the length of the wall, and the side width is 30-80mm. It is a 0.8-2.0mm metal thin plate with decorative and waterproof effect; the wall body takes the side where the metal shell is located as the outer side, and consists of 30-100mm lightweight high-specific-strength high-porosity concrete and a 0-50mm insulation layer from the outside to the inside. , 100-160mm lightweight concrete with high specific strength and low porosity. The exterior wall panel of the present invention solves the problems of heavy weight, poor waterproof effect, poor thermal insulation effect, and difficulty in assembly that occur in current building wall panels.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to exterior wall enclosure materials used for house construction, in particular to an assembled self-insulating metal decorative exterior wall panel. Background technique [0002] With the improvement of building energy-saving requirements, the integration of light weight, high strength and thermal insulation is the development trend of building materials. The traditional wall adopts a masonry wall, and at the same time, an external thermal insulation layer is added to the outside of the masonry wall. [0003] At present, the main types of wall panels that can be used as prefabricated external wall panels in China are: load-bearing concrete rock wool composite external wall panels, thin-walled concrete rock wool composite external wall panels, concrete polystyrene composite external wall panels, and concrete perlite composite external wall panels. Wall panels, steel mesh cement insu...
