Energy-saving domestic architecture with cast-in-place industrial gypsum bearing wall and manufacturing method thereof

Abstract

The invention discloses an energy-saving domestic architecture with a cast-in-place industrial gypsum bearing wall and a manufacturing method thereof. The method comprises the following steps: pouring industrial gypsum slurry into a wall body template in the field to manufacture the gypsum bearing wall of the domestic architecture; afterwards, performing pouring for gypsum / concrete compound building floor or house cover on the gypsum bearing wall, after the completion of the pouring, erecting a bottom template of the building floor or the house cover in advance; and arranging prefabricated industrial gypsum molded cases onto the bottom template at equal intervals, and performing concrete pouring after bars are arranged among the industrial gypsum molded cases and at the upper parts thereof, so as to manufacture the gypsum / concrete compound building floor or house cover on the gypsum bearing wall body. Due to the adoption of the method, the construction cost is low, no reinforced concrete structure is required for the wall body support, the structure is reliable, the construction is easy, the thermal insulation performance is good and the energy saving effect is obvious. The domestic architecture is particularly suitable for low-storey and small-bay domestic architectures in rural.

Description

technical field [0001] The invention relates to an energy-saving residential building with cast-in-place industrial gypsum load-bearing walls and a manufacturing method thereof, belonging to the technical field of residential buildings with low floors (2-3 floors) and small bays (3m-5m). Background technique [0002] Industrial gypsum mainly refers to the large amount of waste slag left after the manufacture of phosphoric acid and the waste slag of coal-fired desulfurization in thermal power plants, steelmaking plants, and steelmaking for power generation. These waste slags are collectively called dihydrate gypsum, and industrial gypsum is formed after processing these waste slags for dephosphorization and sulfur , collectively referred to as hemihydrate gypsum, which has the chemical and physical properties of natural gypsum, how to make these "industrial solid waste resources" is one of the three principles of the national circular economy. Circular economy is the general...

Problems solved by technology

In construction engineering, how to use industrial gypsum as a building material has been widely used. A lot of work has been done in these years. One of the important measures is to make industrial gypsum into blocks, which can be used in small high-rise and high-rise reinforced concrete frame filled walls in cities, but the amount Smaller, residential buildings constructed of industrial gypsum blocks for the majority of rural residences are still rare. The main reason is that the unit price of rural residential construction is only 1 / 2 of the urban residential construction unit price, such as urban construction price of 1300 yuan / m 2 , 650 yuan / m in rural areas 2 , and industrial gypsum is processed into bags of powder, then made into blocks, and then built one by one. This traditional construction technology is used to build rural houses with low-rise small bays. The unit price has greatly broken through, making industrial gypsum masonry Block rural residential buildings, it is difficult to apply on a large scale

As far back as 2008, the inventor of the present invention has just disclosed the technical scheme of the non-load-bearing wall body that adopts industrial gypsum cast-in-place to form in the filling wall of small high-rise and high-rise reinforced concrete frame structure and frame-shear wall structure (referring to Patent application number CN200810305454.4, patent document of invention name "Reinforced Concrete Structure System Using Phosphogypsum as Wall Material On-Site Casting Construction Method", although a large amount of industrial gypsum can be used as wall building material in this technical solution , but because the wall cannot be used as a load-bearing wall, its load-bearing must rely on the reinforced concrete structure system as a support, so its cost is still high, and it is not suitable for rural buildings.

Therefore, the existing technology of using industrial gypsum as a building material is still ideal.
