Description

technical field [0001] The invention relates to the field of house construction, in particular to a house assembled with composite plate modules of a three-dimensional light steel frame structure and a construction method thereof. Background technique [0002] Energy saving, land saving, water saving, and material saving are very important in housing construction. It is not only related to the energy consumption of housing, but also involves the rational use of limited resources on the earth. At present, my country's nearly 40 billion m 2 Among the existing buildings, 99% are high-energy buildings; nearly 2 billion m 2 95% of buildings are still high-energy buildings, and their energy consumption per unit area accounts for about 28% of the total energy consumption. In addition to the energy consumption of building materials production, the energy consumption for buildings has accounted for 40% of the total energy consumption of society. It is not difficult to see from thes...

AI Technical Summary

Problems solved by technology

[0003] Elaborate according to several representative categories: 1. Wooden houses: The wooden houses produced in factories greatly shorten the construction period, save the time and cost of secondary decoration, reduce noise pollution and construction waste, and there is no Wet operation reduces the waste of water resources. The disadvantages are: poor fire resistance, poor corrosion resistance, poor heat preservation effect, low energy saving rate, and consumption of forest resources.

2. Steel structure houses. At present, most enterprises that produce industrialized houses use steel structure building systems. The most mainstream are houses with light steel frame structure systems and light steel dense purlin shear wall structure systems. The construction methods are: The first step is to build the steel structure on site; the second step is to nail and hang maintenance panels on the surface of the structure; the third step is to cast on-site or directly fill the insulation materials and sound insulation materials for walls, floors, roofs and other maintenance structures; Decoration, etc., its advantages are: low cost, fast construction speed, short construction period, good seismic performance, etc., but due to the different technical means, processing technology, construction methods and maintenance materials used, there are also different defects. Disadvantages: (1) There are generally defects of low degree of industrialization. The industrialization rate is less than 30%, and more than 70% of the processes need to be completed on the construction site. The materials on site are small in size and many in specification, and structural errors are prone to occur during the construction process. And delay the construction period; (2) The house constructed by welding operation will lead to structural deformation and increase the structural error. At the same time, the anti-corrosion treatment caused by insufficient on-site supervision will seriously affect the service life of the house; (3) Color steel plate is used for maintenance The fireproof performance of the board house is poor, the corrosion resistance is poor, and the service life is short; (4) the use of cast-in-place method to fill the insulation concrete increases the construction period, pollutes the environment, and wastes water resources; (5) uses polyphenylene and rock wool materials as fillers The materials of this method are easy to age, have poor corrosion resistance, are not environmentally friendly, and some are flammable and have potential safety hazards; (6) light steel frame structure systems usually cover the inner and outer surfaces of the steel structure with plates that play the role of maintenance and thermal insulation. The amount of steel used in the structure is large, and the plates are thicker, which greatly increases the thickness of the wall, reduces the actual use area of ​​the house, and causes waste of land; (7) The steel structure of the house in the light steel dense purlin structure system is very thin and dense , resulting in too many processing and construction procedures, long construction period, resulting in waste of labor and time

The disadvantage is that due to the constraints of transportation conditions, the length, width and height of a single house are limited, the use of space is limited, the layout of the house is relatively small and crowded, and the shape is relatively simple, the thermal insulation performance is poor, and the living comfort is not high. Can only be used as temporary construction

Due to the existing differences in the production and construction of the prior art, the respective deficiencies are also different; (1) the modular production process of the reinforced concrete structure uses mold casting to form, and the mode of on-site combination connection is mostly plugging and reconnecting Concrete filling joints are used for curing and fixing, so the disadvantages are that the initial equipment investment is large, the material itself has poor thermal insulation performance, and the heat energy consumption is high, which needs to increase the time and cost of energy-saving secondary construction; wet work cannot be avoided on site; the materials are heavy and the components are plugged The fixing process consumes a lot of mechanical work and time costs; the process of making or installing many embedded parts and pendants on the concrete structure is time-consuming and laborious; (2) The most important and most vulnerable place for steel structure modular buildings is the processing Component connection problems, cold bridge problems and fire protection problems

Improper handling of the details of each problem will lead to duplication or increase of procedures, extension of construction period, reduction of structural durability, and generation of safety hazards
