With the development of the continuous advancement of science and technology, the materials people use to construct stadium bleachers are constantly changing at an extremely fast rate. From soil, wood, bricks to reinforced concrete, people hope to find a way to improve construction efficiency and reduce construction costs. At the meantime, and demountable metal structures have emerged.
The current construction industry is in the process of comprehensive upgrading of industrial modernization. The modernization of the construction industry includes assembly, informatization, standardization, greening, and integration of design and construction.
With the continuous advancement of science and technology, the materials people use to construct stadium bleachers are also changing at an extremely fast rate. From soil, wood, bricks to reinforced concrete, people hope to find a way to improve construction efficiency and reduce construction costs. At the meantime, and demountable metal structures have emerged. And it is a historic breakthrough for the development of construction industrialization.
Compared with the traditional cast-in-situ reinforced concrete and masonry stadium bleachers, the prefabricated metal structure bleachers use the important components of the bleachers, including beams, panels, columns and seats, which are produced in the factory, and have been tested successful and then transported and installed onsite immediately. It broke the traditional construction method of “Qin brick and Han tile” for thousands of years, and completely subverted the traditional concrete stadium with the “standardization” of all structural components and the “industrialization” of the construction method.
Disadvantages of traditional concrete bleachers:
1. Approval: long time in the preliminary examination and approval procedures
2. Design: bleachers design and construction are completely out of touch;
3. Construction: dust and noise will be caused during the construction process, which will seriously affect the surrounding environment. Long time construction and more complicated management may increase safety accidents. Btw, the quality is difficult to guarantee, and the acceptance time is longer.
4. Installation: The installation of the bleachers and seats is disconnected, which may cause problems such as water leakage and easy damage. The maintenance cost is high and the service life is short. And the fixed position concrete bleachers cannot be moved, and cannot be recycled and reused.
Based on traditional concrete bleachers, the demountable steel structure bleachers have made many improvements in fabrication, avoiding the various shortcomings of the traditional concrete bleachers.
Advantages of demountable metal bleachers seats:
1. Demountable steel structure bleachers is a kind of equipment purchase, which can greatly save the time and cost in preliminary approval procedures for engineering projects.
2. The design, production, installation and after-sales of the demountable metal structure bleachers are all completed by the same company. Free customized services are available, and the intermediate links are fully connected. All services will greatly save time and costs.
3. By analysis of the cost, the entire production process adopts factory standardized prefabrication, high-precision equipment inspection, strict trial assemblies before leaving the factory and on-site assembly installation, which reduces the construction cost of the stands.
4. The post installation speed of the bleachers is also faster. All the components are assembled on site after produced in the factory. This will not only reduce the waste of materials during the construction process, but also greatly reduces the construction waste at the construction site. In this way, the situation of uncontrollable quality bring by climate, on-site environment and human factors will be better. The workers labor intensity and time will greatly reduce. More convenient and orderly cross-operation will decrease installation period. No dust and noise will be brought to the construction site since the material stacking site during construction is reduced, and this will be more environmental friendly.
5. The whole bleachers is made of metal materials, which have the characteristics of ductility, high structural safety, higher seismic resistance and higher resistance to horizontal loads. The metal material is a green and environmentally friendly material with the characteristics of rust-resistant, corrosion-resistant, beautiful and durable. The bleachers require low maintenance cost is low and the service life is longer.
Therefore, it can be said that many advantages of demountable metal structure stands are unmatched by traditional concrete bleachers.
Analysis of demountable metal structure bleachers market prospect
1. Economic benefits: Under the market economy system, the construction industry such as the construction and operation of sports stadium must pay attention to economic benefits.
2. The National policy: Due to the non-renewable land resources, the Ministry of Construction has issued a document to prohibit the use of solid clay bricks. And the government is vigorously promoting the development of demountable buildings.
3. Market environment-competition growth: With the rapid increase of domestic competitions and international events, many provinces plan to build more sports stadium and upgrade existing stadiums. In the meantime, the requirements on the standards of professional stadium will be higher than before,
4. Material advantages: In comparison with materials, the “Strength to density ratio” of metal materials is generally smaller than that of wood and concrete. And steel structures are relatively light, it is about 50% lighter than reinforced concrete structures. The concrete structure bleachers use a large amount of rebar and cement, and the structure cannot be changed after it is built.
5. Structural advantages: The metal structure has a small cross section, which can increase the effective area of the building by about 8% compared with the reinforced concrete structure.
6. Energy saving and environmental friendly: Compared with traditional structure buildings, metal structure buildings have obvious advantages in environmental protection, energy saving, high efficiency, and manufacturing production.
7. Construction advantages: The steel structure bleachers use the factory on-site assembly prefabrication, which has the characteristics of short construction period, less requirement for labor, simple construction site, and environmental protection.
