Prefab house is a house construction system that uses a light steel structure frame and other thermal insulation and decoration materials to integrate production and field installations in the factory. The main features of this house are safety, comfort and fast construction.
Compared with traditional residences, prefabricated houses have the following advantages:
First, the insulation function
Prefabricated house: Use high-efficiency energy-saving system, fill glass fiber wool in the keel grille of the wall as insulation material, and use extruded board or polyurethane insulation material in the outer wall to avoid the "cold bridge" phenomenon of the wall and reach better Insulation effect. Completely reached the national energy-saving code of 65%.
Traditional residence: high thermal conductivity, average thermal insulation function
Moistureproof and breathable
Light steel prefabricated villa: Use high-efficiency energy-saving system. The entire periphery of the wall is sealed with moisture-proof seals using one-way breathing paper to adjust the indoor humidity and humidity. Indoors, the insulation cotton with aluminum foil veneer can completely block the entry of humid air.
Traditional house: no overall moisture-proof method, poor breathability
Third. Seismic strength
Prefabricated house: The construction is light in weight and has good durability. Because the “cage” structure has good integrity, it has the least damage under the effect of earthquake load, and it is easy to rescue when an earthquake comes
Traditional construction: brittle structure, severely damaged under earthquake loading
Fourth, fire resistance rating
Prefabricated house: all materials used for exterior and interior walls can satisfy the requirements of fire rating
3e Prefab House
Traditional house: better
Five. Structure span
3E prefab house: can complete a wide range of diversified, rich structural methods
Traditional house: a single way to complete a large span, costing a lot of data
Six. Construction cycle
Prefabricated house: Compared with the traditional brick structure, it can save half or more construction time, and you can move in after completion. Founding cycle about 2 months
Traditional residence: long construction period, no construction during cold weather
Seven, factory prefabrication
Prefabricated houses: most structures such as keel, floor, and roof truss can be prefabricated in the factory and standardized production
Traditional house: very few prefabricated components, you can buy as much as you like
Eight, take back
Prefabricated houses: primary structural components can be recovered and reused
Traditional House: Unrecoverable
Nine, low-carbon environmental protection
Prefabricated house: The construction process is dry operation, no pollution and noise during the construction process, and the light steel structure system can be recycled.
Traditional houses: lots of construction waste and noise
Ten, utilization rate
Prefabricated house: The light steel structure wall is thin, and the yield rate is about 15% higher than that of traditional construction.
Traditional house: the walls are too thick and the room price is low
Eleven convenient installations
Prefabricated house: The construction process is the assembly process of the factory's prefabricated components. Simple and clean construction, all dry work construction
Traditional houses: the construction process is messy and requires a long-term water extraction protection cycle
Twelve, appearance style
Prefabricated houses: sensitive planning, free from the constraints of traditional residences, strong artistic appreciation of the appearance of residences
Traditional house: single style
