Light steel villa model specifications
What are the model specifications of light steel villas
Light steel villa is also called light steel structure house. It is mainly made of light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology. After accurate calculation and the support and combination of accessories, it is produced with reasonable bearing capacity. of a house. The light steel villa has the advantages of fast on-site construction speed, light weight, good seismic performance, energy saving, sound insulation and defense. The main materials and specifications required for light steel villas are as follows:
1. Light steel frame
The main structure of the light steel villa is made of light steel keel synthesized by hot-dip galvanized steel strip through cold rolling technology, which has the advantages of high density, high strength and stability. There is also a super-strong hot-dip galvanized layer of 275g/㎡, which can ensure long-term anti-corrosion effect in special environments, and at the same time has the performance of earthquake resistance and wind resistance. meet national standards.
2. OSB board
(1) OSB board, also known as OSB board, is a kind of shavings with a length of 40-100 mm, a width of 5-20 mm and a thickness of 0.3-0.7 mm, which are made of small-diameter wood, thinning wood and wood core by special equipment. , and then it is a kind of directional structural board made by deoiling, drying, sizing, directional paving, hot pressing and other processes.
(2) The OSB board has the advantages of easy processing, moisture resistance, no joints, no gaps, cracks, good overall uniformity, high internal bonding strength, super nail holding ability, environmental protection level E1, no formaldehyde release, etc.
3. Glass fiber cotton
Glass fiber wool is an inorganic non-metallic material with excellent performance. It has the characteristics of antibacterial and mildew resistance, aging resistance, corrosion resistance, ensuring a healthy environment, and excellent thermal insulation performance.
4. Moisture-proof breathing paper
(1) The moisture-proof breathing paper is made of a special new polymer material. The surface of the polymer material has an extremely fine microporous structure, and the minimum diameter of the water droplet is about 0.02mm, while the diameter of the water vapor molecule is only 0.0000004 mm, there is a huge gap between the two. According to the diffusion principle of concentration gradient difference, water vapor can freely pass through the micropores, while liquid water and water droplets cannot pass through the breathing paper material because of their surface tension, so the breathing paper has excellent waterproof performance and vapor permeability. performance.
(2) The moisture-proof breathing paper has excellent waterproof performance and can be tightly wrapped around the building's periphery to protect the building from rain erosion. Moisture-proof breathing paper is also the most ideal and excellent material for creating buildings that breathe.
5. Extrusion board
Extruded board is a kind of board with continuous and uniform surface layer and closed-cell honeycomb structure produced by extrusion of polystyrene resin and other additives. The extruded board has extremely low water absorption (almost no water absorption), and has the characteristics of moisture resistance, airtightness, light weight, corrosion resistance, low thermal conductivity, high compression resistance, aging resistance, long service life and low thermal conductivity. .
6. Cement board
Cement board is a kind of building slab processed and produced with cement as the main raw material.
7. Gypsum board
Gypsum board has the characteristics of light weight, high strength, thin thickness, sound insulation and heat insulation, good fire resistance, the ability to adjust indoor humidity, and make living comfortable.
8. Asphalt shingles
(1) Asphalt shingles are also called fiberglass shingles, linoleum shingles, and fiberglass tire asphalt shingles. Asphalt shingle is a new high-tech waterproof building material on the market, and it is also a new type of roofing material used in building roof waterproofing.
(2) Asphalt shingles have: diverse shapes, wide application range, heat insulation, thermal insulation, light roof load-bearing, safety and reliability, simple construction, low comprehensive cost, durability, no worries about breaking, rich colors, beautiful and environmentally friendly, waterproof, durable Corrosion, wind resistance, dustproof and self-cleaning characteristics.
9. The commonly used thicknesses of the main materials required to build light steel villas are as follows:
(1) Keel: 75mm, 90mm
(2) Ou Song board: 9mm, 12mm, 15mm
(3) Rock wool: 50mm, 75mm, 100mm
(4) Calcium silicate board: 6mm, 8mm, 10mm, 12mm
(5) gypsum board: 9.5mm, 12mm
(6) XPS insulation board: 20mm, 40mm, 50mm
(7) SBS waterproof membrane: 3mm, 4mm
(8) External wall hanging board: 7.5mm, 15mm, 18mm
