Description

Technical Field

[0001] The utility model relates to the technical field of building steel structures, in particular to a prestressed steel structure main beam suitable for house interlayers. Background Art

[0002] In recent years, the leap-type mezzanine house and leap-type mezzanine office building have been favored by many owners and enterprises due to their unique design and flexible space layout. This type of building is divided into two floors in the vertical direction, providing a variety of space options for living and working.

[0003] In terms of interlayer construction, there are currently two main methods: First, through cast-in-place reinforced concrete floor slabs, which are closely integrated with the main structure of the building, have strong integrity, and can withstand large weights and earthquake shocks, but the construction process is relatively complex, the cycle is long, the cost is high, and strict evaluation of wall conditions is required. Second, the use of steel structures to build floor slabs has many advantages such as light weight, fast construction speed, and low cost, so it is very popular. However, its stability performance is relatively weak, especially when the span of the main beam of the steel structure reaches a certain level, it may cause structural instability, thereby posing a safety hazard.

[0004] In order to enhance the stability of the steel structure main beam, the current measure commonly adopted in the industry is to add a support structure under the steel structure main beam. Although this method can effectively improve stability, it inevitably increases the occupation of indoor space, which not only reduces the space utilization rate, but also affects the overall aesthetics.
