Technical Field
The utility model relates to a U type connecting plate intensive node that is used for girder steel and wide steel core concrete column to be connected, but wide application is connected with the rigid coupling of wide steel core concrete column in H shaped steel roof beam among many high-rise steel construction.
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 facilitate the pouring of 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 150mm. In addition, the weakening of the diaphragm by the grouting holes cannot be too large for the force transmission requirement in the node area, 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, and a steel structure is a good assembly type building product and has extremely superior seismic resistance. How to apply a steel structure to a housing system, to fully develop the characteristics of steel structure industrialization, and to satisfy functional requirements of housing construction 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 the steel column cannot be too small, and the building function requires that the section of the steel column cannot be too large. I provided a neotype banded enhancement mode node that is used for girder steel and wide steel core concrete column to be connected by department, its connected form is: when the steel beam is rigidly connected with the short edge of the wide steel tube concrete column, a reinforcing plate is arranged at the position where the short edge of the wide steel tube concrete column is connected with the upper flange and the lower flange of the steel beam, and the flange of the steel beam is connected with the wide steel tube concrete column through the reinforcing plate. The position that is connected at wide steel core concrete column minor face and girder steel web sets up the connecting plate, and the girder steel web is connected with wide steel core concrete column through the connecting plate. In addition, pasting plates are arranged on the outer sides of two long edges of the wide steel pipe concrete column and correspond to the upper flange and the lower flange of the steel beam, and the pasting plates are connected with adjacent reinforcing plates.
However, with the development of steel structure assembled, the automatic welding processing of the mechanical arm in the factory has gradually become the mainstream, and the welding of reinforcing plate and flitch can obviously increase the difficulty of automatic welding of the mechanical arm and make time in the former connection type to prolong the construction cycle, be unfavorable for automated production's development.
