On-site spraying and filling fabrication method for inorganic fiber wall

Abstract

The invention discloses an on-site spraying and filling fabrication method for an inorganic fiber wall, which is used for fabricating walls between top boards and bottom boards on site. The method comprises following steps: installing keels horizontally and vertically between a roof and a floor to form internal wall supports; fixedly mounting a shingle at one side of the internal wall supports to form a wall skeleton with one side open; inorganic fiber and binder are synchronously and uniformly sprayed on an inner side surface of the mounted shingle; the inorganic fiber is bonded with the shingle by means of the binder; the wall skeleton is filled with the inorganic fiber through spraying layer by layer and is bonded with the keels to form a heat insulation layer; after the filling is completed, binder is uniformly sprayed on the surface of the heat insulation layer; finally, a shingle is also fixedly installed on the other side of the internal wall supports to form an enclosed wall skeleton; therefore, a wall body is formed by the wall skeleton and the heat insulation layer thereof. The invention relates to the field of buildings and provides an on-site spraying and filling fabrication method for inorganic fiber walls having excellent heat insulation and sound insulation performance.

Description

technical field [0001] The invention relates to the field of construction, in particular to a preparation method for on-site spraying and filling of inorganic fiber 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 common practice t...

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
