Is the floor of the steel structure building cast-in-place or steel?

The floor of steel structure building is made of steel plate as the core, and then concrete is poured on the outer layer. In steel residential buildings, H-beams and thin-walled cold-formed C-beams and Z-beams are used to make composite or building skeletons, and color-coated profiled steel plates or sandwich color steel plates are used for roofs and walls.

The study of high strength steel in steel structure greatly improves its yield point strength; In addition, new steel products such as H-beam (also known as wide flange steel), T-beam and profiled steel plate should be rolled to meet the needs of long-span structures and super high-rise buildings.

In addition, there is a light steel structure system, without thermal bridge, the building itself is not energy-saving. This technology solves the thermal bridge problem with clever special connectors. Small truss structure makes cables and water pipes pass through the wall, which is convenient for construction and decoration.

Extended data feature

1, high strength and light weight.

Steel has high strength and high elastic modulus. Compared with concrete and wood, the ratio of its density to yield strength is relatively low, so under the same stress conditions, the steel structure has small cross section, light weight, convenient transportation and installation, and is suitable for structures with large span, high height and heavy load.

2. The steel has good toughness and plasticity, uniform material and high structural reliability.

It is suitable for bearing impact and dynamic load and has good seismic performance. The internal structure of steel is uniform and close to isotropic isotropic body. The actual working performance of steel structure accords with the calculation theory. So the reliability of the steel structure is high.

3. The manufacture and installation of steel structure is highly mechanized.

Steel structure members are easy to manufacture in factory and assemble on site. Factory mechanized manufacturing of steel structure members has high precision, high production efficiency, fast on-site assembly speed and short construction period.
