Abstract
The utility model discloses a rectangular concrete filled steel tubular column and steel beam semi-rigid node structure. An upper T-shaped steel connecting part and a lower T-shaped steel connecting part are arranged at the position where a rectangular concrete filled steel tubular column is connected with an I-shaped steel beam and penetrate rib-penetrated type high-strength bolts to be fixed on the rectangular concrete filled steel tubular column, the end head of the I-shaped steel beam is placed between the two T-shaped steel connecting parts, and an upper flange and a lower flange of the I-shaped steel beam are fixed with the upper T-shaped steel connecting part and the lower T-shaped steel connecting part through high-strength friction-type bolts. The rectangular concrete filled steel tubular column and steel beam semi-rigid node structure is simple and convenient to install, steel products are saved, and the bending moment bearing capacity of nodes is controlled by controlling the size of the connecting parts and the number of the high-strength bolts, so that nodes have good plastic rotation capacity and can dissipate energy well under the seismic action, and the design concept of ductile nodes is achieved.
Description
Technical field
The utility model belongs to building engineering field, relates to a kind of Steel concrete combining structure.
Background technology
Development along with building structure, research and the application of steel-concrete combined structure are launched rapidly, so far become a kind of generally acknowledged new structural system, itself and steel work, wooden construction, masonry structure and reinforced concrete structure are arranged side by side, to be expanded into the fifth-largest structure.In recent years, concrete-filled rectangular steel tube is simple because of joint form, and second moment of area is large, good stability, the particular advantages such as be convenient to take precautions against fire, and uses increasingly extensive.But these concrete-filled rectangular steel tube frame construction nodes mostly adopt direct welding manner; The employing bolt that has connects extended end plate or internal partition, after the concrete in managing reaches some strength, shank of bolt is applied prestressing force; Above-mentioned connected mode all belongs to the rigid joint structure, and there are the problems such as ductility of joint is poor, welding residual stress is large in the rigid joint structure, occurs easily brittle fracture under geological process.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of concrete-filled rectangular steel tube frame welding form, a kind of rectangular steel-tube concrete column and structures with semi-rigid joints structure to be provided.
The technical solution of the utility model is: a kind of rectangular steel-tube concrete column and structures with semi-rigid joints structure, it is characterized in that, it is on the position of the connection i-shape steel beam of rectangular steel-tube concrete column, be provided with up and down two T-steel connectors, the T-steel connector is fixed on the rectangular steel-tube concrete column by the through ribbed high-strength bolt, the termination of i-shape steel beam is placed between two T-steel connectors, by high strength friction-type bolt the upper bottom flange of i-shape steel beam and two T-steel connectors up and down is fixed together.
Compared with prior art, the utlity model has following advantage:
1, owing to adopt the through ribbed high-strength bolt, its effect is equivalent to internal partition, can effectively transmit pulling force and the pressure of bottom flange on the girder steel; The effect that not only has internal partition is compared with the external partition joint form, have power transmission directly, save steel, guarantee the advantages such as architectural space, more be conducive to manage inner concrete build and closely knit.
2, the bottom flange is connected with the rectangle steel tube wall by the T-steel connector on the i-shape steel beam, T-steel is connected with the rectangle steel tube wall by the through ribbed high-strength bolt, power transmission is clear and definite, simple structure, i-shape steel beam is connected with T-steel by high strength frictional property bolt, simple structure, easy construction is by the gauge size of control T-steel connector and the quantity of high-strength bolt, the size of control joint rigidity.
3, this joint structure is simple, easy for installation, save steel, size by the control connection part and the quantity of high-strength bolt control the moment of flexure ability to bear of node, make node have preferably plastic rotation, under geological process, better dissipation energy is realized the design concept of ductility joint.
Description of drawings
Fig. 1 is front view of the present utility model, shows among the figure that the rectangular steel-tube concrete column two sides is provided with i-shape steel beam;
Fig. 2 is top view of the present utility model, shows among the figure that rectangular steel-tube concrete column is provided with i-shape steel beam on four sides.
Among the figure: the 1-rectangular steel-tube concrete column; The 2-i-shape steel beam; The 3-T structural steel connecting member; 4-through ribbed high-strength bolt; 5-high strength friction-type bolt.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings:
As shown in Figure 1 and Figure 2, a kind of rectangular steel-tube concrete column and structures with semi-rigid joints structure, it is on the position of the connection i-shape steel beam 2 of rectangular steel-tube concrete column 1, be provided with up and down two T-steel connectors 3, T-steel connector 3 is fixed on the rectangular steel-tube concrete column 1 by through ribbed high-strength bolt 4, the termination of i-shape steel beam 2 is placed between two T-steel connectors 3, by high strength frictional property bolt 5 the upper bottom flange of i-shape steel beam 2 and two T-steel connectors 3 up and down is fixed together.
Show among Fig. 1 that the rectangular steel-tube concrete column two sides is arranged with i-shape steel beam; The T-steel connector 3 usefulness through ribbed high-strength bolts 4 on two sides are fixed together.
Show among Fig. 2 that rectangular steel-tube concrete column is provided with i-shape steel beam on four sides; The T-steel connector 3 usefulness through ribbed high-strength bolts 4 of two sides symmetry are fixed together.
