Background
In recent years, steel structure building industrialization and assembly type building policies are continuously issued, green buildings and building materials are actively promoted, and steel structures and assembly type buildings are vigorously developed. The assembled steel structure system is a building produced by manufacturing house units or components according to the specifications of unified and standard building parts and then transporting the building units or components to a construction site for assembly in place, and is characterized by light building weight, energy conservation, environmental protection, high construction speed, high industrialization degree and the like, can solve the problems of low building industrialization level, low building construction labor productivity, low quality of traditional house products and the like in China, and is suitable for the development of the building industry in China.
The beam column node is a basic component of a frame structure, has great influence on the stress and safety of the whole structure, once the connection is damaged, a structural member cannot play a role, whether the structure is reasonable or not is directly related to the safety and reliability of the structure, and the construction method of the beam column node directly influences the construction speed of engineering and the assembly degree of the structure. Compared with a rectangular steel pipe, the round steel pipe has a better constraint effect on core concrete, but the round steel pipe concrete column has the defect of inconvenient node connection, and is particularly more serious in connection with an I-shaped steel beam. Therefore, if the problem of the beam-column joint of the circular steel tube concrete column is to be solved, the joint connection mode needs to be started.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved is as follows: aiming at the defects of the prior art, the rigid reinforced connection node of the circular steel tube concrete column and the I-shaped steel beam is provided for overcoming the defect that the circular steel tube concrete column and the I-shaped steel beam are inconvenient to connect.
For realizing the purpose of the utility model, the technical proposal to be adopted is as follows: the utility model provides a rigid reinforcement connected node of circular steel tube concrete column and I-shaped girder steel, includes circular steel tube concrete dysmorphism post, node component and I-shaped girder steel, and its circular steel tube concrete column comprises circular steel tube and core concrete, connects gradually node component and I-shaped girder steel, and the node component comprises semicircle wall steel pipe, short steel beam, horizontal stiffening plate and vertical stiffening plate. According to different use requirements, the short steel beam of the node component can be welded on the node component according to a straight line shape, an L shape, a T shape or a cross shape.
The utility model discloses in, on the position of circular steel tube outer wall connected node component, polish this part in advance and handle, with node component card in this position, carry out the accurate counterpoint with the direction of connection of I-shaped steel roof beam, penetrate first bolt hole with first high-strength bolt, it fixes to screw up the bolt. And after screwing, welding the upper end and the lower end of the semicircular wall steel pipe with the round steel pipe column by adopting a fillet weld, fixing the web plate of the I-shaped steel beam and the short steel beam web plate of the node member together by using a second high-strength bolt, and welding the flange part.
The utility model discloses an among the preferred scheme, the internal diameter of semicircle wall steel pipe only slightly is greater than the external diameter of circular steel tube, can laminate smoothly when guaranteeing the installation on the one hand and carry out the screens, and on the other hand stops to cause the fastening not jail because the diameter differs greatly.
The utility model discloses an among the preferred scheme, the I-shaped cross-section that the horizontal stiffening plate of node component and vertical stiffening plate formed will be with short girder steel and I-shaped girder steel cross section phase-match, can make the change along with used I-shaped girder steel model among the actual conditions.
The utility model provides a rigid reinforcement connection node of circular steel tube concrete column and I-shaped girder steel has following advantage:
construction convenience, because the circular steel tube in node district, node component, I-shaped girder steel, high strength bolt etc. all can be in mill's prefabrication processing and weld together, consequently, in the engineering operation, only need hoist and mount to the assigned position after carry out the connection can.
The node area adopts that the transverse stiffening plates and the like are welded on the node components to transmit the bending moment of the steel beam, and the vertical stiffening plates are welded to transmit the shearing force of the steel beam, so that the stress is reasonable. In addition, no reinforcing steel bars are arranged in the node area, and the node area is only unfolded and operated outside the steel pipe, so that the condition that the reinforcing steel bars in the node area are crowded does not exist.
