What is the light steel structure housing?
Light steel structure residence is cold bending forming of thin wall steel structure as bearing skeleton, with light wall materials as enclosure structure of residence building.In the United States, Japan, Australia and other developed countries, light steel structure building system has already been used for residential buildings, such as light steel structure residence in the United States has accounted for about 25% of the average house, and it is comparatively mature technology.
Compared with traditional residential structure system, light steel structure residence has the following features:
(1) the construction speed, short construction period;
(2) the materials of lightweight, high strength, good seismic performance, high security;
(3) space arranged flexibly, can satisfy the requirement of resident of multi-function;
(4) can realize the industrialization and the industrialization of residential construction.
In the section where the main features are:
(1) light weight structure, foundation construction soil quantity is little, little of destruction of land resources;
(2) the component of an area small, thickness of palisade structure is small, can increase the use of building area.
What is the difference between light steel structure and chongqing steel structure?
Determine the structure of chongqing steel and light steel structure is no a unified standard, many experienced designer or project manager is often said can't fully understand, but we can with some data comprehensive consideration and judgment:
1, the main components: steel plate thickness is greater than or equal to 10 mm, light steel structure with less.
Steel weight of the 2, per square meter: greater than or equal to 50 kg/M2, can be regarded as heavy steel structure.
3, workshop crane lifting weight: greater than or equal to 25 tons, can be thought of as heavy steel structure.
Light steel structure is a young and great vitality of steel structure system, has been widely used in industrial and agricultural, commercial, service building, can also be used in old house floors, reconstruction and reinforcement and lack of building materials, transportation inconvenience region, the tight, activity type can demolition construction, etc., so much the owners, mainly has the following features:
1) using efficient light thin walled profile, light weight, high strength, small occupied area.
Based above dry method, 2) didn't wet homework, inner decoration and so on easy to in place at a time.Profile after galvanized, after coating, beautiful appearance and anti-corrosion, help reduce palisade and decorating costs.
3) structure design, detail design, computer simulation, factory, construction site installation, etc. With small time synchronization.
Based above 4) dry method, there is no wet operations, in adornment such as easily in place at a time.Profile after galvanized, after coating, beautiful appearance and anti-corrosion, help reduce palisade and decorating costs.
5) easy to expand the column spacing and provide greater space space, can reduce the height and increase the building area (residential practical area of up to 92%), obvious advantages in terms of floors, reconstruction and reinforcement.
6) indoor plumbing electrical line all hidden in the walls and floors, flexible layout, modify convenience.
7) wide scope of application of new wall materials, extensive use of daylighting, ventilated condition is good.
8) house can move, all materials can be recycled will not result in a waste, in accordance with sustainable development strategy.
In the application of the residential building is very quickly, and is to the multilayer residential building development.Non-residential construction with four layers below the door type light steel structure is given priority to, generally more than 20 m span, widely used in large-span light industry, electronics, construction of the warehouse, processing workshop, also have applications in daily supermarket, temporary housing, hangar, etc.
