Description

Split type special-shaped cold-formed steel bone concrete column module of steel structure building

Technical Field

The invention belongs to the field of steel structure buildings, and particularly relates to a spliced special-shaped cold-formed steel bone concrete column module of a steel structure building.

Background

Compared with the traditional reinforced concrete and common steel structure systems, the cold-formed steel structure system has the advantages of more diversified shapes, lighter and thinner structure system, no pollution on site, lower construction cost and higher comprehensive benefit, and becomes an important component and development trend of the assembled steel structure building.

The cold-formed steel structural column is the most main stressed member of a cold-formed steel structural system. Wherein the cold-formed steel structure corner post not only bears the vertical load such as the dead weight of the structure, but also bears the wind load, the earthquake acting force and the like. The characteristics of bearing capacity, anti-bending capacity and the like are paid great attention. Meanwhile, the cold-formed steel structure corner post has the highest contact probability with the external environment, and the fire resistance and the corrosion resistance of the cold-formed steel structure corner post are also concerned. The cold-formed steel structure side column is directly or indirectly subjected to constant load transferred by members such as beams, plates and walls, and is easier to be subjected to eccentric action compared with the cold-formed steel structure center column. The characteristics of bearing capacity, anti-bending capacity and the like are paid great attention. The cold-formed steel structure center pillar not only directly or indirectly receives the internal force transmitted by the members such as beam, plate and wall, but also has the characteristics of bearing performance, anti-seismic performance, fire-proof and corrosion-proof performance and the like. The cold-formed steel structure center pillar is also the most diverse and flexible member of the cold-formed steel house splicing form. Most of the existing researches are made by splicing C-shaped, U-shaped and Z-shaped cold forming steels, but most of the different section forms of the cold forming steel structure columns have the defects of low buckling strength and low bearing capacity, and most of the researches do not distinguish the stress performance of the structure columns of different types. The cold-formed steel structure system is limited to low-rise buildings with small depth and small span, and the requirements of the society on large-span space and high-rise buildings are difficult to meet. In addition, although the splicing of the cold-formed steel structural column and the prefabricated wall plate provides a support for the placement of the water and electricity pipelines, a reinforcing and fixing device is still required in actual construction, the performance of the structural column can be weakened to different degrees in the process, and the purchasing work and the site construction of the reinforcing device also improve the construction cost for erecting the water and electricity pipelines.
