Embodiment Construction

[0036] (1) Assembly of the wall mold. The bottom plate, the two opposite calcium silicate wallboards 6 and the two side panels are closed, assembled and connected to obtain a wall mold, and the two adjacent panels are connected by the mortise joint parts 7 that cooperate with each other, and the high-strength screw rod 3 passes through The two opposite calcium silicate wallboards 6 reserve holes and connect the two calcium silicate wallboards 6, and the two ends of the high-strength screw 3 pass through the inner fastener 4 and the outer fastener 5 They are respectively fixed on the calcium silicate wallboards 6 on the two sides, and the thickness of the walls is 120mm.

[0037] (2) Filled with ceramsite. Set the bulk density to 300kg / m 3 The hollow ceramsite 1 is poured into the interior of the wall mold from the top of the wall mold and filled and the top cover is fixed. Check the size of the gaps around the wall after the assembly is completed, and use glass glue to seal...

Abstract

The invention discloses a grouted ceramsite light-weight composite wall board and a preparation method of same. The light-weight composite wall board is prepared through the steps of: with a wall bodymould provided with a hollow cavity as a body, filling the hollow cavity with hollow ceramsites as an aggregate; injecting grouting gypsum mortar into the hollow cavity until overflow in a pressure jet-injection manner; stopping grouting and performing maintenance to obtain the grouted ceramsite light-weight composite wall board. In the method, the hollow ceramsites have lighter weight and stronger mechanical strength than common ceramsites, so that the wall board has high strength and low density. Meanwhile, nano-aerogel added to the gypsum mortar contains a large amount of nano-scale pores,so that high-effective heat preservation and insulation effect is supplied. The wall board is free of problems, such as seams, swelling and cracks, which frequently appear on a multi-layer-slurry wall board.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a lightweight thermal insulation composite wallboard based on nano-modification technology and grouting technology and a preparation method thereof. Background technique [0002] With the further strengthening of national energy conservation, environmental protection and ecological construction policies, green demonstration projects in the construction industry have been continuously promoted, and building wall materials are developing in the direction of energy saving, soil saving, waste utilization, environmental protection and building function improvement. Traditional partition wall materials consume a lot of non-renewable resources and cause serious pollution problems. At the same time, wet construction results in high labor intensity and increased construction costs. Existing light-weight thermal insulation interior wall panels are generally made of glass f...
