Is the light steel villa worth building, will you regret not building it?

The main material of the so-called 'light steel house' is steel structure frame supplemented by colored metal profiled steel plates. Since its frame structure is mainly portal steel frame, its architectural performance is based on portal steel frame. Derivatize. Generally speaking, light steel residences have been recognized by all sectors of society for their simplicity and clarity. However, some people say that this kind of house is too light and not strong, and you will regret it if you build it. Let's technically interpret the system of light steel houses and the advantages of light steel to see if the light steel house is worth building.

〖1〗Floor structure of light steel structure residential building

The floor of light steel structure residential building is made of cold-formed thin-walled steel frame or composite beam , Floor OSB structural panels, supports, connectors and other components. The materials used are oriented strand board, diamond board, and plywood. These lightweight floors can withstand loads of 316 to 365 kilograms per square meter. The weight of the floor structure system of the light steel structure house is only one-quarter to one-sixth of the traditional domestic concrete floor system, but the structural height of the floor will be 100-120 mm higher than that of the ordinary concrete slab.

〖2〗Roofing system for light steel structure residential buildings

Light steel structure residential roofing system is composed of roof truss, structural OSB panel, waterproof layer, light roof shingles (metal or asphalt shingles). The roof of light steel structure can have various combinations in appearance. There are also various materials. Under the premise of ensuring the waterproof technology, there are many options for appearance.

〖Three〗Wall structure of light steel structure house

The wall of light steel structure house is mainly composed of wall frame column, wall top beam, wall It consists of bottom beams, wall supports, wall panels and connectors. Light steel structure houses generally use the inner transverse wall as the load-bearing wall of the structure, and the wall columns are C-shaped light steel components. mm, the light steel structure residential wall structure layout method can effectively bear and reliably transmit vertical loads, and the layout is convenient.

〖IV〗Insulation and energy saving technology of light steel structure residential buildings

In order to ensure the thermal insulation effect of light steel structure residential The thermal insulation material used in the utility model can be used for a long time and can keep thermal insulation. In light steel structure houses, in addition to filling glass fiber between the walls and pillars, a layer of thermal insulation material is attached to the outside of the wall to effectively cut off the thermal bridge from the wall pillar to the outer wall panel; the joists between floors are filled with glass fiber , Reduce heat transfer through floors; all interior walls are filled with glass fiber between wall columns to reduce heat transfer between household walls.

〖V〗Building fire protection technology

A key issue for light steel structure houses is the application of fire protection technology. Light steel structure houses are on both sides of the wall Fire-resistant gypsum board is attached to the ceiling of the floor, and 25.4 mm thick (1 inch) gypsum board is used for protection of ordinary fire walls and sub-family walls to meet the fire protection requirements. In addition, non-combustible filling is used between the wall columns and the floor joists. fiberglass.

〖Six〗Building sound insulation technology

The light steel structure house is filled with glass wool between the inner and outer walls and the floor joists, which effectively prevents the transmission through the air For the audio part of the audio frequency, and for the impact sound transmitted through solids, the following structural processing is performed: for the household wall, two wall columns are used to form two walls with intermediate gaps; and for the small keel used for the fixed gypsum board for the ceiling, The elastic structure with small cut grooves is used to effectively reduce the transmission of solid sound between floors.

〖Seven〗Structural features

The bearing structure adopts cold-formed thin-walled light steel skeleton, high-strength, anti-corrosion steel coil (yield strength 550Mpa, zinc The thickness of the aluminum alloy coating is 270g/m2), and the thickness of the steel is 0.75mm. It is directly rolled into various types of structural components through computer-aided manufacturing special equipment according to the design requirements. The vertical load-bearing members are densely arranged columns, and the distance between the large columns is 600mm. Plane load-bearing components: the roof adopts truss net, the grid size is 600X600mm, the floor (ground) surface adopts truss beam, the large and medium distance is 1200mm, and the door and window lintel adopts small truss beam.

The wall enclosure is made of light-weight and high-strength enclosure materials or diamond boards.

The roof, floor, and internal and external walls are made of waterproof and thermal insulation materials.

The roof and floor systems are made of waterproof glass fiber tiles, waterproof membranes, thermal insulation cotton, stringers, and hanging fireproofing plasterboard.

〖Eight〗Construction Features

The production of steel structure adopts computer-aided manufacturing technology, and the whole process of production is made of professional equipment controlled by computer software Completed, to ensure that the accuracy error of component manufacturing is within half a millimeter that is difficult to achieve manually. Except for the foundation construction, the rest are all dry work construction and installation.

〖Nine〗Design features

Cold-formed thin-walled light steel structure system is a mature technology in Australia. Special CAD technology is used in the design - light steel structure construction design software, and the generated design files can be directly input into the processing equipment for automatic processing.
