The Reasons Why High-rise steel structure hangar are Vigorously Promoted

In recent years, structural steel construction compared to brick structure has obvious advantages in  environmental protection, energy saving, high efficiency, factory production. Humans began to use iron since 70's of the seventeenth Century, the beginning of the nineteenth Century the use of wrought iron bridges and the construction of housing, steel structure than the history of the development history of the development of reinforced concrete structure is long, its vitality is growing. In American, such as the construction of the lower two floors of the following non residential construction market has 70% architectural metal products.

The Reasons High-rise Steel Structure Buildings are Vigorously Promoted shown as belows:

1.Save construction time a lot, construction will not be influenced by the seasons

2.Increasing the use of residential space area, reduce construction waste and environmental pollution.

3.Building materials can be reused, driving the development of other new building materials industry

4.Good performance of the seismic resistant, easy modification, flexible and convenient, bring comfortable to people.

101 high-rise buildings around the world has been completed, 16 buildings of reinforced concrete structures, steel structure of steel concrete mixed structure building 59 and 27 different types of buildings; we can see that the development of steel structure will promote the rapid development in construction industry, metallurgical industry, machinery industry, automobile industry, agriculture, oil industry, commercial, transportation.

To ensure the safety of the steel structure workshop should possess characteristics

1.good sealed performance
Since the welded structure can be completely sealed, airtight and watertight some of the requirements of a good high-pressure vessels, large oil tanks, gas tanks, piping and other steel plate and shell structures are used.

2.has a certain degree of heat resistance
Temperature within 250 ℃, the changing nature of the steel is small, the temperature reached above 300 ℃, the strength is gradually decreased, reaching 450 ℃ ~ 650 ℃, the intensity is reduced to zero. Therefore, the temperature is not higher than steel can be used in the case 250 ℃. There are special fire protection requirements in their own building, the steel must be maintained refractories.

3.poor corrosion resistance of steel
Steel's biggest drawback is easy to rust. New construction of steel structures generally need to be carefully rust, galvanized or paint brush. After a certain time interval, again, paint brush, high maintenance costs.

4.elastic, plastic, strong seismic performance
Under the same conditions bearing capacity, steel and reinforced concrete structures, wooden structure compared to smaller components, lightweight, easy to transport and install. Because of homogeneity and toughness of steel materials, may have large deformation, can well withstand dynamic loads, with good seismic capacity. Among them, the yield ratio is an important parameter to measure the ability of steel hardening. The lower the yield ratio, the ability of steel to resist strong earthquakes stronger. European construction steel requirements yield ratio is less than 0.91, while Japan requires construction steel yield ratio of less than 0.80. Meanwhile, the steel has good elastic, plastic and impact resistance, in general, the steel's ability to adapt to the dynamic load compared strong, its good ductility and energy dissipation capacity can ensure that it does not because of changes in the external load suddenly rupture, seismic steel which is very favorable.

In addition, the steel structure of these characteristics, not only can effectively reduce the project cost structure, but also making it a distinct advantage in dealing with special foundations and so on.

Crack control measures of exterior steel structure warehouse

The connecting way of thermal insulation layer and protective layer and structure layer, currently has the following kinds: connecting rod bracket;Inclined rod bracket;Long screw;Adhesives. The above four kinds of connection methods have their own characteristics, but the comprehensive comparison, the former three construction more troublesome the fourth scheme involving the problem such as compressive strength and durability, therefore recommend the following four kinds of simpler scheme: nail;Expansion bolt;Embedded bar or plastic reinforcement scheme;Glue, nail combining with solutions. This scheme not only construction is convenient, but also has good durability.

Second, to prevent and remove the protective layer and act the role of surface cracks, the measures to reduce the protective layer stress concentration and contraction stress.
Protective layer and act the role of surface cracks mainly has the following several reasons:
1.protective layer and the compressive strength of insulation layer is low or appear empty drum;
2.the protective layer and act the role of surface shrinkage deformation is larger, leading to cracks;
3.because the Windows and doors hole in stress concentration, which leads to the protective layer and act the role of surface cracks.
Aimed at several of the major causes of the cracks, should take the following measures:
4.the steel mesh or use wire mesh sandwich rock wool board enhancement layer, on the one hand, steel mesh can strengthen structural layer and insulation layer and protective layer connection, on the other hand can also be dispersed protective layer and the surface of the shrinkage stress and stress concentration, so as to achieve the purpose of reduce and prevent the cracks.At the site of the wall cracks easily still need to adopt measures to local Settings to strengthen network.
5.the higher compressive strength, small shrinkage deformation and has certain elasticity micro expansion of anti-cracking mortar or polymer mortar.Due to the rock wool board texture is soft, so the thickness of anti-cracking mortar with 25 mm to 30 mm advisable.
6.the protective layer partition and seam sealing waterproof processing, in order to reduce the shrinkage and temperature stress.
Three, to solve the protection problem of weathering layer and the facing layer.
Good protective layer and act the role of weathering on the surface can use two methods:
7.in the protective layer tile is stuck outside, but this method increased the wall body weight and cost, as there is a requirement for high decoration construction is feasible.
8.outside the protective coating of high elasticity, good weather resistance exterior wall coating, because the coating has good elastic-plastic and waterproof function, and has good anti-cracking and weather resistance, so the impact on the protective layer and insulation layer is a protective effect.

Plastic doors and Windows in the application of steel structure supplier

Plastic doors and Windows in the technical features of steel structure on the material of window of model steel door, in addition to the glass and a small amount of metal parts (button, lock), is mainly specialized formula of rigid PVC (polyvinyl chloride) material, has the following characteristics:
1.Because the material is PVC in melt state through die extrusion molding, finalize the design.So can be formed in the steel structure project the fine structure of all kinds of functions, such as improve the strength to place the steel main cavity, to improve the performance of heat preservation, sound insulation multi-cavity structure, drainage channel, mounting hardware structure, can be a powerful guarantee of the doors and Windows function requirements.

2.The white plastic doors and Windows color requirements for indoor decoration has a wide range of adaptability, double-color coextrusion successively applied in recent years, laminating, spraying technology can make the plastic window outdoor color more rich, satisfies the requirement of the color of the building facade.

3.Plastic window frame, fan Angle are welding, Angle type window due to the improper process may be exempted from group, in steel structure engineering from cracks in the possibility of a leak.

4.Plastic doors and Windows material recycling, reuse, because PVC resin is a thermoplastic material, therefore can be repeated in the steel structure engineering thermoforming, become the new products, recycling, accord with environmental protection requirement.

5.The biggest advantages of plastic window energy saving, and reflects the excellent price performance ratio in this respect.First in terms of material production energy consumption, unit weight of the PVC is only 1/8 of the steel, aluminum 1/16. And when recycling reuse don't need to smelting, casting, just put the material after broken, can be used as a raw material.Energy consumption.This is good for the shortage of resources situation in our country.

6.Insulation: in the steel structure engineering of PVC plastic coefficient of thermal conductivity is 11250 aluminum alloy, steel 1400. Plastic doors and Windows for housing dissipating energy (both heating and refrigeration and air conditioning), only about 26% of steel window dissipating energy, aluminium alloy window lost 30% of the energy.Made of plastic doors and Windows in the steel structure engineering of heat preservation and heat insulation effect and acoustic noise reduction function will be more than 30%, if coupled with use double deck glass, so can greatly improve efficacy.

Outdoor steel structure corrosion paint matching program introduced

Nature disasters again knock improving the quality of prefab steel structure

Further enhance the public cognition to the steel structure, especially the steel structure housing and accept ability, and the government intensify financial preferential policy support, in the market will be crucial to the development of steel structure industry. The building in the future is main in high-level, high-rise, the seismic energy saving, low carbon environmental protection, which is the steel structure building the unique advantages of "high, big and light". Currently, prefabricated steel structure civil industrial technology innovation and strategic alliances are included in the national pilot industrial technology innovation and strategic alliances.

Architect said that Chile is widely used "strong column weak beam" Seismic Design: by breaking the beam to buffer the earthquake energy, but the column is not broken, as far as possible to ensure that the whole building will not collapse, thereby reducing casualties to the greatest extent. Therefore, good shock resistance steel building has been large-scale promotion, mitigation achieved remarkable success.
Steel buildings are excellent in light weight, small inertia force, emergencies seismic performance characteristics after several verification, making daily living more safe and secure. Promote the use of steel structure housing, both green energy and can increase the effective use of space, but also more effective than the traditional steel seismic building.

Our country is a frequent earthquake disaster power, according to statistics, housing structures and materials issues are important factors directly cause casualties.

In response, the Chinese construction metal structure association suggested that earthquakes is a wake-up call, countries should promote steel structure residence in earthquake zones, abandons the traditional low construction practice. Steel structure for steel mechanics performance, has the incomparable flexibility of traditional concrete structures. Under the same seismic force, the steel structure will not break;And reinforced concrete structure is relatively larger rigidity, when the external force than can withstand the limit can partial damage or completely destroyed. Take the steel structure at moderate height as an example, using steel structure building is reinforced concrete structure weight lost about a third, seismic action can be reduced by 30% ~ 30%, on the ground can also reduce the load per unit area of more than 25%. Thus, steel structure building earthquake resistance performance is superior to traditional architecture.

The Characteristics of the prefabricated warehouse supplier

Brick of steel structure, it refers to the building of the wall of the vertical bearing structure, pilaster use brick or block masonry, column, beam, floor, roof boarding, such as truss using reinforced concrete structure.Informally, brick structure is a small part of reinforced concrete structure, and most of the brick wall bearing is also called the reinforced concrete composite structures.
Because the brick structure of the main bearing structure is clay brick, so the shape of a brick and intensity determines the intensity of the building.It can be said that the shape of the brick the rule, the higher the strength of the mortar, mortar joint the thinner the uniform and the strength of the masonry, the higher the building life is longer.

Brick structure advantage mainly displays in: because brick is the smallest standardized components, to the construction site and the construction technical requirements is low, can build by laying bricks or stones into various shapes of the wall, all can produce.It has good durability, chemical stability and atmospheric stability.Can save cement, steel and wood, do not need the template, cost is low.Simple construction technology and construction equipment.Brick is superior to sound insulation and insulation concrete and other wall materials, thus the use of the most common in residential construction.
