Basic Introduction:

Light steel villa, also known as light steel structure house, its main material is made of hot dip galvanized aluminum steel strip by cold rolling technology synthesis of light steel keel.

The aluminum-zinc alloy structure of aluminum-zinc plated steel plate is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600℃. The whole structure is composed of aluminum-iron-silicon-zinc, forming a dense four-element junction crystal, thus forming a strong and effective barrier to prevent corrosion factors from penetrating.

Light steel characteristics:

1. Corrosion resistance:

"55% Aluminum zinc coated coil" corrosion resistance comes from the aluminum barrier layer protection function, and zinc sacrificial protection function. Aluminum forms an insoluble oxide layer that acts as a barrier when zinc sacrificial protects the cut edges, scratches and scratches of the coating. Aluminum zinc alloy steel coil has been exposed to various atmospheric conditions for more than 20 years. It has been proved that 55% aluminum zinc plate has better edge protection function than galvanized steel plate and 5% aluminum zinc plate.

2. Heat resistance:

The heat resistance of 55% al-Zn alloy steel plate is better than that of galvanized steel plate and similar to that of aluminized steel plate. Aluminium-zinc alloy steel plate can be used in high temperature environment up to 315 degrees.

3. Reflexivity:

The high reflectivity of 55% Aluminum zinc alloy steel plate makes it a barrier against heat. Aluminium-zinc plate has nearly twice the thermal reflectivity of galvanized steel plate, so it can be used as roof and panel without painting to achieve energy efficiency.

4. Paint:

Because of the excellent adhesion between the zinc layer and the paint of the aluminized zinc plate, it can be painted without pretreatment and weathering treatment when used as a sign plate for general purposes. Galvanized steel requires weathering and pretreatment.

Basic composition:

Light steel villa system construction

Light steel wall structure system, by light steel multi-ribbed beams and columns and consistent with the maintenance structure of the joint force, the physical performance index is excellent, short construction period, good thermal insulation effect, is a new type of green building structure system of energy conservation and environmental protection.

1. Basic system

Light steel structure house light weight, only for the brick structure house about one-fifth, reinforced concrete structure house about eighth, so can greatly reduce the cost of foundation construction, light steel structure house foundation generally use strip foundation.

(1) Light steel structure has light dead weight, which can greatly reduce the cost of basic engineering;

(2) The moisture-proof design of the foundation effectively prevents the invasion of moisture and harmful gases;

(3) Reasonable anchorage mode to ensure the reliable connection between the foundation and the main body.

2. Wall system

The external wall system is generally between 120-200 mm, due to the thin wall, light steel structure housing than traditional housing increased by 10%-15% of the actual use area, than traditional housing to increase the indoor use area of more than 90%, indoor space can be flexibly separated. Pipelines can be arranged in the reserved holes of wall, floor and roof components, with good concealment and more beautiful appearance.

(1) The wall is filled with glass fiber cotton, which has good heat preservation, heat insulation and sound insulation performance;

(2) Breathing paper waterproof breathable, can effectively adjust indoor air humidity, make living more comfortable, and effectively prevent mold inside the wall;

(3) The pipeline is buried in the wall and does not occupy the indoor space.

3. Floor system

The floor is made of high-strength hot-dip galvanized C type and U type light steel components. The floor beams are arranged in accordance with the standard modulus and the same spacing and multiple ribs. The floor beams are covered with strict moisture-proof and anticorrosive structural plates, forming a strong earthquake-resistant floor system.

(1) The combined structure of structural plate and floor steel beam is firm and stable;

(2) All kinds of water and electricity pipelines are hidden in the floor structure, do not occupy the height of the building;

(3) Filling glass fiber cotton in the sandwich has remarkable effect of heat preservation and insulation, sound absorption and sound insulation.

4. Roofing system

The roof frame is composed of a variety of light steel components, generally triangle roof frame and T-shaped roof frame, which can easily and flexibly achieve a variety of complex roof modeling. The general roof adopts colorful asphalt tiles, which has good waterproof performance and highlights beauty and quality.

(1) The composite roof has the functions of rain proof, weather resistance, heat insulation and so on, which can realize a variety of modeling;

(2) Ventilation circulation design, always keep the air fresh.

5. Structural components

All the structural components are made of high strength galvanized steel to ensure the service life of the house. All the structural components are cold pressed by the factory precision mechanical assembly line, and the dimensional accuracy is mm, which is unmatched by other structures.
