Construction factors

　　1）In the process of construction, the roof enclosure is not protected, and the roof is trampled randomly, which damages the flatness of the roof, and even cracks appear, the amount of sealant is insufficient, the position is not correct, too many rivets are pulled, and no waterproof treatment is carried out.)

　　2）There is no anti-corrosion for gutters. Some construction units only brush antirust paint or asphalt paint when they are anti-corrosion for gutters. After a period of use, gutters are seriously corroded.

　　3）Due to the large span of roof slab in steel structure engineering, there is lap joint in roof slab. Although polyurethane sealant and 138900 suture nail are used in lap joint and other places, it is difficult to meet the design theoretical standard during installation, resulting in rain leakage.

　　4）There is no slope in the gutter transverse direction, and a slope of at least 0.5% shall be reserved during fabrication.

　　5）The construction of key nodes is careless.The internal corners of the parapet and other roots are not made into an arc as required or the arc is too small, the end of the coil is not sealed tightly, the upper white iron sheet is deformed, the fixed points are rare and the sealing materials are not well sealed, the root of the pipe protruding from the roof is not sealed tightly, the leveling layer around the pipe is not higher than the nearby leveling layer, and the flashing height of the waterproof layer is not enough.In case of rain during the construction of the thermal insulation layer, the exhaust slot is blocked and the exhaust hole is set unreasonably, which causes the thermal insulation layer to be immersed in water for a long time.The rigid roof has cracks, and the waterproof sealing paste at the split joint is not firmly bonded with the side wall of the joint and seeps.

    Now, the state’s support for small and medium-sized enterprises is still very strong, with various preferential policies.This has led people to start their own businesses. In the same way, many small and medium-sized enterprises are springing up.Careful friends all invent: compared with the traditional factory buildings, the new steel layout factory buildings are more and more used. Why abandon the traditional factory buildings and start the new steel layout factory buildings?What advantages does steel layout plant have?

Let’s meet:

　　1. the steel layout is light in construction quality, high in strength and large in span.

　　2. the construction period of steel layout construction is short, and the investment cost is correspondingly low.

　　3. steel layout components are made in the workshop to eliminate the amount of work on site, shorten the construction period, meet the property requirements, not only save resources, but also eliminate some unnecessary pollution.

　　4. steel layout and construction have high fire resistance and strong corrosion resistance.

　　5. the steel layout workshop has reliable production quality, accurate size, convenient placement, and is easy to share with related parts.

　　6, light weight and high strength, the weight of the balance building made of steel layout is about 1 / 2 of that of reinforced concrete residence; it is satisfied with the necessity of large-scale room of residence, and the utilization area is about 4% higher than that of reinforced concrete residence.

　　7. the steel layout is convenient for construction and removal, no pollution is accepted, and less pollution is caused during fabrication and demolition.These advantages are the cost of steel layout.He uses these winds to support the “umbrella of peace” of life.

　　8, quiet and reliable, good anti-seismic and wind resistance performance, strong load ability, anti-seismic ability can reach eight, and it is its style that big earthquake does not fall, medium earthquake does not damage.
