Fire performance analysis of light steel structure villa houses
Green light steel structure villa Building ---- energy, environmental and land conservation
The main structure of light steel structure villa is steel skeleton, and the steel structure has good fireproof performance, so the fireproofness of light steel structure villa is one of its major features.
The degree of temperature resistance of steel structure is 450℃~650℃, more than this high temperature will lose the ability to withstand the pressure, resulting in the steel skeleton twisted deformation, in the absence of protective measures under the steel structure of the fire-resistant limit of 15 minutes or so, therefore, we must carry out fire protection treatment of the steel structure to overcome the shortcomings in this regard, the purpose of which is to improve the fire-resistant limit of the steel structure to the limit of the scope of the design specification.
Cladding, water-filled water jacket, shielding, intumescent materials are four ways that we must pay great attention to, through which we can effectively block the flame directly burning steel structure, reduce the speed of heat transfer and delay the time of temperature rise of the steel structure.
This fireproof performance of light steel structure villa is not available in other forms of construction, the safety is much higher, is a new choice for modern housing.
Maybe You Ask
1.How Long Will The Light Steel Villa Be Used And Its Safety?
Service Life:
The load-bearing structure of light steel villa is designed to have a service life of up to 90 years,
Which is three times as long as that of ordinary houses, and there is no problem in normal use for seventy years.
Safety:
Light steel villa meets the building requirements in earthquake and hurricane resistance, very strong, can resist 9 level earthquake, 12-13 level typhoon.
At the same time, light steel components can direct the current generated by lightning strikes into the ground to protect the occupants from injury.
2. What Materials Are Used In Light Steel Villas?
Construction:
The light steel villa is treated with hot-dip galvanised or almost pure zinc metal coating for corrosion prevention and will not rust.
The whole house is grounded and the circuit is safe.
Materials:
Calcium silicate version is used for the inner wall of the light steel villa, and gypsum board is used for the ceiling.
Calcium silicate board is high strength, light weight, and has good workability and non-combustibility.
3. How About The Lightning Protection And Moisture-proof Effect Of Light Steel Villa?
Lightning Protection:
the galvanised material of light steel villa is a complete lightning protection system when it is closely connected with the ground,
And there is no need to do special lightning protection measures.
Moisture-proof:
light steel villa adopts closed moisture-proof system, which can effectively control the corrosion of steel and ensure the structure life is greater than the service life of the residence.
4. Are Light Steel Villas Really Fireproof?
Light steel villas do have fire resistance.The main structure of light steel villa adopts light steel keel, light steel itself is non-combustible material, which improves the fire safety of the building to a certain extent.
Light steel villa will use all kinds of fireproof materials to assist in the construction process. For example, parts such as walls and roofs will be filled with insulation materials with good fireproof performance, such as glass fibre cotton, which are basically non-combustible.
At the same time, the walls, roofs, floors and other parts of the light steel villa also use fire-retardant materials such as osone boards, calcium silicate boards and other fire-retardant materials. These materials will not burn when encountering an open flame, but will only blacken and carbonise, thus effectively preventing the spread of fire.
However, it is also important to note that despite the better fire resistance of light steel villas, the performance of the steel will be affected under high temperature conditions. When the temperature exceeds a certain level, the strength and hardness of the steel will be significantly reduced and even deformed.
Therefore, in order to improve the fireproof performance of light steel villa, additional measures such as fireproof coating and fireproof wall body are often required.
5.Is The Quality Of Light Steel Villa Reliable?
The quality of light steel villa is reliable under the premise of reasonable design, standardised construction and selection of high quality materials.
Light steel villa adopts light steel keel as the main structural support material, and this structural system has the characteristics of light weight, high strength, fast construction and flexible design.
The construction process of light steel villa is very innovative, light steel structure in the factory based on accurate design is cut into specific sizes, complete precision processing and manufacturing, transported to the construction site for assembly, abandoning the traditional building site masonry brick wall, long time mixing cement and other complicated processes, which greatly saves the construction time and reduces the construction cost.
However, The Quality Of Light Steel Villas Is Also Affected By Some Factors.
For example, the quality of light steel keel varies in the market, and some unscrupulous merchants use inferior materials to substitute good ones, which can affect the structural safety of the houses.
Therefore, when buying light steel keel, you need to check the product inspection report and choose materials with high hot-dip galvanising content and thickness that meet the standard.
In addition, the professional level and construction experience of the construction team also has an important impact on the quality of light steel villa.
Unqualified construction teams or construction personnel lacking professional knowledge may lead to various errors in the construction process, thus affecting the quality of the house.
Therefore, be sure to choose a qualified construction team with a good reputation.
