High Rise Buildings Steel Structure Construction / Multi Floors Metal Residence Buildings
Steel Structure High Rise Buildings / Multi Floors Metal Residence Buildings. This is a six floors steel frame structure residence buildings. Welded H-section steel beams and columns are connected by high strength bolts to compose the main frame structure.
Glavanized steel floor deck is used to be the floor base support. For pre-assembled steel components, to guarantee it complying with the design requirements and quality standards, all the steel structure are fabricated in our factory. We also consider the deformation values such as weld shrinkage allowance of the length dimension of the column, beam, support and other components.
Qingdao Ruly Steel Engineering Co.,Ltd is a professional steel structure fabrication and construction company for light and heavy steel structure project. Our service include design, fabrication for all the steel structure components and insullation panel, installation on site.
| 1 | Steel structural material has high strength and light weight | The steel structure has high strength. Compared with the concrete structure, the steel structure beam and the column cross-sectional area are small, which can increase the effective use area. Generally, the cross-sectional area of the high-rise steel structure column accounts for about 3% of the building area, and the cross-sectional area of the high-rise concrete structure accounts for 7%-9% of the building area. |
| 2 | Steel structure construction speed is fast | Most of the steel structure is produced in the factory and transported to the site for integral assembly by welding or bolting. It can be used all day, because the steel structure itself can be used as a load-bearing structure for the construction load to reduce the formwork during construction, thus not only reducing costs, but also greatly speeding up Construction speed. The construction speed of the steel structure is about 1.5 times that of the concrete structure. |
| 3 | Convenient pipeline layout | In the structural space of the steel structure, the truss type member or the member having the cavity can be used, so that the arrangement of the pipeline is convenient, and the replacement and repair of the pipeline is convenient. However, if a concrete structure is used, the beam should not be opened, and the pipe generally passes under the beam, thereby occupying a certain space. In the case of the same floor height, the floor height of the steel structure can be smaller than the floor height of the concrete structure, which can reduce the area of the outer wall. |
| 4 | The steel construction environment is less polluted | When steel structure is constructed, sand, stone, soil, cement and other materials are rarely used, and pollution problems such as dust flying, waste accumulation and noise are avoided from the root wood. |
| 5 | Steel structure construction conforms to sustainable development policy | The steel structure industry is a green-bag environmental protection construction industry. Its utilization of resources and energy is relatively reasonable, and has little damage to the environment.. |
