Description

Steel pipe concrete column with exhaust honeycomb duct, lattice structure and steel structure factory building Technical Field The utility model belongs to the technical field of building construction, and particularly relates to a concrete filled steel tubular column with an exhaust flow guide pipe, a lattice structure and a steel structure factory building. Background The steel pipe concrete column can effectively exert the advantages of two materials, namely steel and concrete, the steel pipe provides transverse constraint for filled concrete, the compressive strength of the concrete is improved, the defect of weak tensile capacity of the concrete is overcome, the filling of the concrete can prevent the steel pipe from local buckling, the whole bearing capacity is far beyond that of the steel pipe and the concrete is singly overlapped, and the steel pipe concrete column has good stress performance and economy, so that the steel pipe concrete column is widely applied to industrial and civil buildings. Steel tube concrete columns are often adopted as the branches of lattice type lower columns in steel-making continuous casting plants, particularly steel rolling plants, shoulder beam webs are inserted into lower column steel tubes and concrete, wherein steel tube components are prefabricated in factories, and concrete is poured in situ. In order to ensure that the concrete is poured compactly, holes are generally formed near the bottom of the steel pipe column, concrete is poured by adopting a pumping jacking method, and ventilation holes are formed in the top of the steel pipe column. Because the crane limb shoulder beam upper cover plate is required to be placed on a crane beam support base plate, and the roof limb shoulder beam upper cover plate is required to be placed on a vertical supporting bracket of a longitudinal wall skin column, the diameter of a lower column limb of a continuous casting plant and a steel rolling plant is generally smaller, and a proper and enough space is difficult to find at two sides of a shoulder beam web plate on the column top to be provided with air holes. Even if the upper cover plate of the shoulder beam is provided with the position provided with the air holes, the overflowed concrete flows downwards along the steel pipe after grouting, if the concrete is not cleaned timely, the welding of the spring plate and the steel pipe outer side pavement beam or the bracket which are longitudinally connected with the upper cover plate of the shoulder beam is affected firstly, and secondly, the later period is difficult to clean up, so that the appearance is affected. If the outside of the steel pipe near the column top is provided with the ventilation holes, the compactness of concrete below the upper cover plate of the shoulder beam is difficult to ensure, the force transmission of the crane beam support is affected, and potential safety hazards are left.
