steel pipe concrete structures are increasingly one of the first choice forms in civil engineering structure design, however, concrete construction and dismantling can cause certain pollution to the environment, and modern wood structures are gradually popularized and developed in China along with the technical progress and the adjustment of national policies. The modern wood has better tensile and compressive strength and ductility, lower wood quality, environmental protection and good fire resistance and corrosion resistance. However, the load bearing capacity of the wood is limited by adopting the wood for load bearing, and the load bearing capacity of the wood is reduced sharply particularly in an environment with alternating dry and wet conditions. Therefore, the bearing performance can be improved by adopting a steel-wood combination mode, the advantages of steel and wood are fully exerted, and an efficient and stable combined structure form is formed.
In addition, in residential and office buildings, the corners of the building are often convex due to the oversized pillar sections, which affects the usable floor area and furniture layout of the house. The large-section column is decomposed into a plurality of small-section columns, so that the phenomenon of convex angles in the chamber can be avoided. At present, the special-shaped columns which are applied more are of a steel pipe concrete combined special-shaped column structure, but concrete is easy to crack, and the problems of insufficient anti-seismic performance, complex construction, environmental pollution and the like exist.
Based on the indirect assembly type round steel pipe-wood combined special-shaped column, the indirect assembly type round steel pipe-wood combined special-shaped column is convenient to construct, simple to operate, good in anti-seismic performance, green, environment-friendly and light in self weight, the anti-seismic performance and the bearing capacity of the indirect assembly type round steel pipe-wood combined special-shaped column are greatly improved through the advantage combination of steel and wood, and the indirect assembly type round steel pipe-wood combined special-shaped column is very suitable for.

(3) and assembling the indirect assembled circular steel tube-wood combined special-shaped column on site: after the component is transported to the site, the tightening rings are sleeved outside the circular steel tubes at intervals, the arrangement positions of the circular steel tubes are the same, the connecting steel plates are tightly attached through bolts, and the tightening rings tightly hoop the circular steel tubes and are fixed; the two ends of the patch piece are fixed at the position of the tightening ring connecting steel plate by bolts and then are transversely and obliquely connected with the tightening ring connecting plate of another steel pipe, namely, the patch piece is arranged horizontally and obliquely at intervals. By adopting the connection mode, two, three or four steel pipes are connected to respectively form I, L, T and a cross-shaped steel pipe combined special-shaped column which are indirectly connected;
furthermore, the tightening rings are three-quarter circular steel belts, half circular steel belts and quarter circular steel belts, and are respectively applied to the middle columns of I-shaped steel-wood combined special-shaped columns, T-shaped steel-wood combined special-shaped columns and cross-shaped steel-wood combined special-shaped columns according to structural characteristics, and the edge columns are all open circular steel belts.
The invention has the beneficial effects that: (1) the section of the column is small, and the column can be wrapped in a wall body, so that an indoor corner is prevented from generating a convex angle, and the defect that the section of a common rectangular column or a common circular column is large in size is overcome; (2) the ductility is greatly improved and the structural bearing performance is improved by adopting a mode of combining steel pipes and wood; (3) the distance between the single steel pipes can be adjusted, so that the large bending rigidity is easy to realize, and the equal stability of the two main shafts is easy to realize; (4) the combined components are prefabricated in factories, and only the bolts are needed to be connected into the special-shaped column on site, so that the construction speed is high, and the precision is high.
