Longma Crane specializes in producing kbk frame steel structures

Jingjiang Longma Lifting Equipment Co., Ltd. is a professional manufacturer of kbk frame steel structures. Welcome to inquire about technical parameters< Br/>
The characteristics of the kbk frame steel structure are high strength, light weight, good overall stiffness, strong resistance to deformation, good material homogeneity and isotropy, and it belongs to the ideal elastic body, which is more in line with the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; Its high degree of industrialization allows for highly mechanized production< Br/>
Steel structures should study high-strength steel to greatly improve its yield point strength; In addition, rolled sections such as H-beams (also known as wide flange sections), T-beams, and profiled steel plates are required to adapt to large-span structures< Br/>
In addition, there is a lightweight steel structure system without thermal bridges, and the building itself is not energy-efficient. This technology solves the problem of cold and hot bridges in buildings with clever special connectors; The small truss structure allows cables and water supply and drainage pipes to pass through the wall, making construction and decoration convenient.

Features

1. High material strength and light weight

Steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the component section of steel structures is small, the self weight is light, and it is easy to transport and install. It is suitable for structures with large spans, high heights, and load-bearing capacity< Br/>
2. Steel has toughness, good plasticity, uniform material, and high structural reliability
Suitable for withstanding impact and dynamic loads, with good seismic performance. The internal organizational structure of the steel is uniform, almost isotropic and homogeneous. The actual working performance of steel structures is in line with computational theory. So the steel structure has high reliability< Br/>
3. High degree of mechanization in steel structure manufacturing and installation

Steel structural components are easy to manufacture in the factory and assemble on the construction site. The factory's mechanized manufacturing of steel structural components has high precision, high production efficiency, fast assembly speed on site, and short construction period. Steel structure is a type of structure with a high degree of industrialization< Br/>
4. Good sealing performance of steel structure

Due to the welding structure being able to achieve complete sealing, it can be used as high-pressure vessels, large oil pools, pressure pipelines, etc. with good airtightness and water tightness< Br/>
5. Steel structure is heat-resistant but not fire-resistant

When the temperature is below 150 ℃, there is little change in the properties of the steel. Therefore, steel structures are suitable for hot workshops, but when the surface of the structure is subjected to thermal radiation of around 150 ℃, insulation boards should be used to protect it. When the temperature is between 300 ℃ and 400 ℃, the strength and elastic modulus of the steel significantly decrease, and when the temperature is around 600 ℃, the strength of the steel tends to zero. In buildings with special fire protection requirements, steel structures must be protected with refractory materials to improve their fire resistance rating< Br/>
6. Poor corrosion resistance of steel structures

Especially in humid and corrosive media environments, it is easy to rust. Generally, steel structures need to be rust removed, galvanized or coated, and regular maintenance is required. For offshore platform structures located in seawater," Zinc block anode protection&RD
