Embodiment 1

[0079] 1) Configure load-bearing concrete. According to the "Ordinary Concrete Mix Proportion Design Regulations" (JGJ55-2000), configure C30 ordinary concrete: 175kg of water, 461kg of cement, 512kg of sand, and 1,252kg of stones. After mixing, pour it into the abrasive tool. The abrasive tool has built-in steel bars. The diameter of the steel bars is 16mm and the spacing is 200mm. Surface leveling, natural maintenance 28d.

[0080] 2) Lay airgel felt with a thickness of 10mm on the load-bearing concrete. The airgel blanket is connected to the concrete by anchor nails.

[0081] 3) Lay the reinforcement layer on the airgel material. The reinforced layer is reinforced mortar containing glass fiber mesh cloth. Fix the reinforcement layer with anchors.

[0082] 4) Make a decorative layer on the outer surface of the load-bearing concrete and reinforcement layer. Both the load-bearing concrete and the decorative layer on the outer surface of the reinforced layer are paints.

Embodiment 2

[0084] 1) Configure load-bearing concrete. According to the "Technical Regulations for Light Aggregate Concrete" (GJ51-90), configure C25 light aggregate concrete: 150kg of water, 300kg of cement, 680kg of sand, and 680kg of ceramsite. After mixing, pour it into the abrasive mold. The abrasive mold has built-in steel bars with a diameter of 16mm. The spacing is 200mm, the surface is leveled, and the natural maintenance is 28d.

[0085] 2) Lay airgel panels with a thickness of 15mm on the load-bearing concrete. The airgel blanket is connected to the concrete by anchor nails.

[0086] 3) Lay the reinforcement layer on the airgel material. The reinforcement layer is a fiber-reinforced cement board. Fix the reinforcement layer with anchors.

[0087]4) Make a decorative layer on the outer surface of the load-bearing concrete and reinforcement layer. The outer surface of the load-bearing concrete is decorated with fluorocarbon paint, and the outer surface of the reinforcement l...

Embodiment 3

[0089] 1) Configure load-bearing concrete. Dissolve 65kg of aluminum sulfate in 200kg of water to prepare an aluminum sulfate solution, and dissolve 23kg of quicklime in 200kg of water to prepare lime water. Put the lime water in the container, slowly add the aluminum sulfate solution under the condition of stirring at 300r / min until the pH value is 7.2, and obtain the translucent ettringite colloid. The premixed dry material is prepared and mixed as follows: Portland cement 400kg, fine sand 500kg, vitrified microbeads 80kg, pebbles 400kg, shale ceramsite 200kg, silicon micropowder 12kg. Add 10kg of glass fiber and 1kg of waterproofing agent to the prepared ettringite colloid, stir for 15 minutes to prepare a premixed wet material, then add the premixed dry material, and continue stirring for 18 minutes. Pour the obtained concrete slurry into the mould, the abrasive tool has built-in steel bars, the diameter of the steel bars is 16 mm and the spacing is 200 mm, the surface is...

Abstract

The invention relates to a load-bearing heat-insulating decorating integrated assembled wall and a manufacturing method, in particular to an assembled wall using an aerogel material as a heat-insulating layer and having load-bearing, heat-insulating and decorating functions. Load-bearing concrete and a decorating layer are arranged inside and outside of the heat-insulating layer respectively. The load-bearing heat-insulating decorating integrated assembled wall has the advantages of light weight, high strength, low-heat-conducting coefficient, attractiveness and practicability, the assembled wall can be quickly assembled on site after being prefabricated and formed in a factory, the assembled wall has remarkable practical significance in development of residential industrialization and green buildings of China, and high-efficiency energy-saving heat-insulating effect of severe cold areas can be improved remarkably.

Description

technical field [0001] The invention relates to a load-bearing, thermal insulation and decorative integrated assembled wall and a preparation method thereof, in particular to an airgel material as the thermal insulation layer, the thermal insulation layer has load-bearing concrete and a decorative layer on the inside and outside, and has the functions of load bearing, thermal insulation and decoration at the same time assembled wall.
