Light steel villa, also known as light steel structure house, its main material is the light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology. After accurate calculation and support and combination of auxiliary parts, it plays a reasonable bearing capacity to replace the traditional house.

Special performance

1、 Compared with traditional residence, light steel villa has its outstanding advantages

(1) Light steel villa light steel structure accessories manufacturing factory and mechanization of a high degree of commercialization.

(2) Light steel villa site construction speed is fast, will not affect the nearby residents, is conducive to civilized construction.

(3) The steel structure building of light steel villa is an environmental protection and sustainable development product.

(4) Light steel villa has light weight and good seismic performance.

(5) The comprehensive economic index of light steel villa is not higher than that of reinforced concrete structure.

(6) Compared with brick concrete residence, light steel villa can avoid the waste of resources caused by burning bricks with soil

(7) Light steel villa can increase the effective use area compared with brick concrete structure because of its small wall thickness;

(8) Compared with the reinforced concrete residence, the light steel structure can be recycled in the future, but the concrete can not be recycled. It must be the construction waste in the future, which will cause environmental pressure. Moreover, it takes 40 years for the concrete to dry completely, so it is easy to cause indoor moisture and humidity, which is not conducive to human health. But the light steel structure does not use concrete at all, so there is no such problem.

(9) Light steel villa has good seismic performance. Since the earthquake activity is left and right and up and down, the light steel structure connected with screws constitutes a safe and stable box, which will not cause wall collapse or floor falling due to earthquake shaking, endangering personal safety.

(10) Dry construction method is adopted in the construction of light steel villa, which will not cause waste of water data. And it saves money.

2、 Floor structure of light steel villa

The floor of light steel villa is composed of cold-formed thin-walled steel frame or composite beam, OSB structural plate of floor, support, connectors, etc. The materials used are oriented particleboard, cement fiberboard and plywood. On these lightweight floors, a load of 316-365 kg per square meter can be carried. The weight of the floor structure system of the light steel villa is only one fourth to one sixth of that of the traditional concrete floor system in China, but the structural height of the floor will be 100-120mm higher than that of the ordinary concrete slab.

3、 Roof system of light steel villa

The roof system of light steel villa is composed of roof truss, structural OSB panel, waterproof layer and light roof tile (metal or asphalt tile). The appearance of light steel roof can be combined in many ways. There are also a variety of materials. Under the premise of ensuring the waterproof technology, there are many options for the appearance.

4、 Wall structure of light steel villa

The wall of light steel villa is mainly composed of wall frame column, wall top beam, wall bottom beam, wall support, wall panel and connector. Light steel villa generally takes the inner transverse wall as the bearing wall of the structure. The wall column is a C-shaped light steel component. Its wall thickness is usually 0.84-2 mm, and the wall column spacing is generally 400-600 mm. This wall structure layout of light steel villa can effectively bear and transfer vertical load, and the layout is convenient.

5、 Heat preservation and energy saving technology of light steel villa

In order to ensure the thermal insulation effect of light steel villa, the thermal insulation materials used in the exterior wall and roof of the building can be used for a long time and can be used for thermal insulation. In light steel villa, in addition to filling glass fiber between wall columns, a layer of thermal insulation material is pasted on the outside of the wall to effectively isolate the heat bridge from the wall column to the external wall panel; glass fiber is filled in the joist between floors to reduce the heat transfer through the floor; glass fiber is filled between the wall columns of all internal walls to reduce the heat transfer between the house and the wall.

4. Building fire prevention technology

One of the most important problems of light steel villa is the application of fire prevention technology. The fire resistance rating of light steel villa is grade 4. The light steel villa is pasted with fireproof gypsum board on both sides of the wall and the ceiling of the floor. The ordinary firewall and household wall are protected with 25.4 mm (1 inch) gypsum board to meet the fire protection requirement of one hour. In addition, the glass fiber filled between the wall column and the floor joist also plays a positive role in fire prevention and heat transfer.

5. Building sound insulation technology

The light steel villa is filled with glass wool between the inner and outer walls and the joists of the floor, which effectively prevents the audio part transmitted through the air. For the impact sound transmitted through the solid, the following structural treatment is made: for the household wall, two wall columns are used to form the second wall with the middle gap; for the small keel of the fixed gypsum board used for the ceiling, the elastic structure with small grooves is used to effectively reduce the impact sound Solid sound transmission between floors.

advantage

The technology and product configuration of light steel structure is very mature, with high degree of industrialization. It is the crystallization of the development of building technology and building materials industry in North America in recent 100 years. The galvanized steel sheet used in building structure has excellent corrosion resistance and durability, and its service life under normal use is 75 years.

The seismic performance of light steel structure is much better than that of traditional concrete and brick concrete buildings. At the same time, due to the light weight of light steel structure, the weight per unit area is only 1 / 4 of the weight of brick concrete structure in the same area, so the foundation treatment is simple and suitable for most geological conditions. Steel structure houses are no longer as worried about termites as wooden houses.

Because the steel materials used in the structure are factory processed, the structural accuracy of light steel villa is quite high, and the structural system of a villa is composed of
