Answer ten questions

1、 Q: is the price much higher than the brick concrete frame structure in rural areas?

A: the cost of a structural building with the same living experience is 30% lower than that of a frame structure, which has been appraised by Tsinghua University and other authoritative institutions. The insulation effect of our 15cm thick composite wall is equivalent to 1 meter thick brick concrete. Apart from Northeast China, which self built house wall is one meter thick? Take our villa and 800, 1000 brick and concrete ratio, is equivalent to take Audi than the elderly scooter.


2、 Q: what are the advantages over brick concrete?

A: safety: earthquake resistance, wind, snow, pest control


Comfort: sound insulation, thermal insulation, beautiful

Fast: short construction period and applicable scope

Environmental protection: low energy consumption, high recycling rate of building materials

High cost performance: large use area and high cost performance


3、 Q: how about sound insulation?

A: sound insulation is much better than brick concrete. Not to mention that most of the brick concrete structures are not in accordance with the national standards, even if the implementation of the national standards of brick and concrete, the standard is lower than that of light steel structure housing. (see relevant documents: the state focuses on promoting energy-saving ecological light steel structure residence)

The sound insulation standard of brick concrete residence is 45 dB for exterior wall and 40 dB for interior wall.

Light steel structure residential standard: external wall 60 dB, interior wall 45 dB


4、 Q: can you really keep heat and save energy?

Answer: compared with the energy-saving and consumption reducing performance of traditional residential form, light steel villa has better thermal insulation performance. On the basis of meeting the structural strength requirements, it can well integrate various heat preservation and energy-saving technologies, and fill JPSG thermal insulation slurry, which effectively separates the cold and hot bridges; the minimum thermal conductivity can reach 0.06w / (m.k); the insulation effect of 15cm thick wall is better than that of brick concrete 24 cm thick wall.


5、 Q: how about durability (most people care about corrosion)?

Answer: all light steel structure keel is made of high-corrosion galvanized steel, which can effectively avoid the corrosion of steel structure in the process of use. The design service life of bearing structure is as long as 90 years, which is 3 times of that of ordinary houses.


6、 Q: water leakage

A: the most annoying thing about traditional buildings is that they leak water. The houses don't leak long after they are built. This is because some foremen, in order to save costs, did not comply with the standards when applying waterproof materials or waterproof layers. Light steel structure buildings strictly implement the national standards for waterproofing, so this situation will not occur.

In addition, because we are an industrial prefabricated structure building, its interface gap is tighter than the traditional building, and the waterproof in production has many advantages over the traditional building.


7、 Q: how long does it take to build a light steel villa?

A: This is determined by the building area. Generally speaking, it takes 1.2-1.5 workers per square meter and 9 people for 300 square meters. The construction takes about 36 to 45 working days. A working day is equal to 8 hours for a worker. This is because the main materials of the light steel villa are produced in the factory. After being transported to the site, it can be directly assembled like assembling a car.


8、 Q: is light steel villa wall material environmentally friendly?

Answer: light steel villa materials are in line with national safety standards, does not contain formaldehyde, benzene, radiation materials that are harmful to human body. And these materials can be recycled, very environmentally friendly. In fact, many people do not know that the red brick we commonly use is very harmful to human body. According to the actual measurement of experts, the fired red brick contains radon and y-ray. The radiation rate of red brick y is 25.03ur/h. If a house with red brick is closed for one night, the radon content is as high as 151 Beck / m3. Living in such environment for a long time can lead to gene damage of human cells and easily breed various diseases.


9、 Q: how thick is the wall of light steel villa?

A: the exterior wall of light steel villa is generally 200 mm, and the interior wall (partition wall) is generally 120 mm. If it is in cold areas such as northeast China, the insulation layer needs to be thickened. The external wall will be thicker than that in other areas. Generally speaking, the wall of light steel villa is thinner than that of traditional brick concrete wall, which can save more use area.


10、 Q: how many floors can light steel villas be built?

Answer: there are two types of light steel villa system. The light steel wall stress system is suitable for buildings with 3 floors and below, and the light steel plate column system is suitable for buildings with 6 floors and below, which can be used for civil and commercial purposes. Moreover, the steel structure has a large span and the internal structure can be handled flexibly.
