Fabrication method of on-site spraying and filling for fireproof lightweight particle walls

Abstract

The invention discloses a fabrication method of on-site spraying and filling for fireproof lightweight particle walls. The method is used for on-site manufacturing walls between top boards and base boards. The method comprises following steps: mounting keels to form inner support in a wall; mounting wall panels at one side of the inner support of the wall to form a wall skeleton with one side open; an inner side surface of the mounted wall panel is coated with fireproof lightweight particles and polyurethane foaming material synchronously and uniformly; the fireproof lightweight particles are glued to the wall panel through the polyurethane foaming material; the wall skeleton is filled with the particles and is glued with the keel to form a thermal insulation layer; after filling is completed, the other side of the support inside the wall is fixedly provided with a wall panel to form an enclosed wall skeleton; therefore, a wall body is formed by the combination of the wall skeleton and the fireproof lightweight particles and the polyurethane foaming material. The invention relates to the field of buildings. The invention provides a fabrication method of on-site spraying and filling for fireproof lightweight particle walls having excellent thermal insulation and sound insulation performance.

Description

technical field [0001] The invention relates to the field of construction, in particular to a manufacturing method for on-site spraying and filling of refractory lightweight particle walls. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption of the whole society. The living area of ​​heating cities in northern my country only accounts for 10% of the national urban living area, but building energy consumption accounts for 40%. The largest energy consumption of buildings in our country is heating and cooling. Compared with developed countries with similar climate conditions, the heating energy consumption per square meter of buildings in our country is about three times that of developed countries. my country is currently making every effort to promote building energy saving by 65%. standard. [0003] Gypsum board and light steel keel are common materials for making partition walls, and it is...

Problems solved by technology

This method is more energy-saving and environmentally friendly than concrete casting or aerated brick stacking. However, because the rock wool is manually cut and filled on site, and the horizontal and vertical keels in the wall increase the amount of labor, often only one working hour is required. Can produce several square meters, low efficiency

In particular, the application of low-cost organic insulation materials such as foamed polystyrene, foamed polyurethane and foamed phenolic formaldehyde in building insulation is greatly limited due to low flame retardancy and fire resistance; foamed perlite, foamed ceramics, foamed glass , foamed cement and other inorganic thermal insulation materials are heavy and have poor thermal insulation effect, and require a large amount of adhesive to bond with the two side panels, and also require a lot of manpower and high cost for cutting
