Technical Field
The utility model relates to a node of girder steel and wide steel core concrete column, concretely relates to single picture peg node that girder steel and wide steel core concrete column weak axis are connected.
Background
In many high-rise steel structures, the girder steel is mostly H shaped steel roof beam, and the steel column is mostly rectangle steel pipe concrete column. The rigid connection of steel beams and steel columns is the most basic measure for providing the overall rigidity and the seismic performance of the structure. The existing common rigid joint is that a transverse partition plate is arranged at the position of a steel column corresponding to a beam flange, and the internal force of the beam flange is transmitted to the steel column through the partition plate, so that the rigid joint is formed. The partition plate is provided with an inner partition plate and a through diaphragm plate, and the inner partition plate and the through diaphragm plate are respectively corresponding to two components of a box-type column and a cold-roll forming high-frequency welding rectangular steel pipe column.
In order to conveniently pour concrete in the steel pipe column, grouting holes and air holes need to be formed in the partition plate, and the diameter of each grouting hole is not smaller than 150 mm. In addition, for the requirement of force transmission in the node area, the weakening of the partition plate by the grouting holes cannot be too large, so that the section width of the steel column cannot be too small, and is generally not less than 350-400 mm. In steel structure houses, the convex column phenomenon can occur at four corners of each functional room of the house due to the overlarge section of the steel column, and the use function of indoor buildings is affected, so that the structural members are hidden in the thickness of the wall body as much as possible, and the section width of the steel members adopted in the houses is preferably controlled to be 180 mm-300 mm.
At present, building industrialization and housing industrialization are being vigorously popularized in China, a steel structure is a good assembly type building product, and the earthquake-resistant performance is extremely superior. How to apply the steel structure to a housing system, fully exert the characteristics of steel structure industrialization, and meet the functional requirements of housing buildings is a very important and urgent task. Therefore, in order to solve the problem of indoor convex columns, a form of adopting wide steel tube concrete columns is provided, the size of the short side of each steel box column is made to be as small as possible, the short side is equal to the thickness of a concrete shear wall, the size of the long side of each steel box column is made to be as large as possible, and the wide steel tube concrete columns are formed so as to meet the requirements of houses on steel structure systems. However, the size of the short side of the section of the wide concrete filled steel tubular column is small, so that a diaphragm plate cannot be arranged in a node area for ensuring smooth pouring of the internal concrete, and the connection with a steel beam cannot adopt the form of the diaphragm plate.
Based on the technical background, the current engineering practice has the contradiction that the partition plate connecting node requires that the section of a steel column cannot be too small, and the construction function requires that the section of the steel column cannot be too large.
