Abstract
The utility model discloses a rectangular concrete filled steel tubular column and box-type steel beam rib-penetrated type node structure. A connecting steel plate is pre-welded on the end face of a box-type steel beam, the width of the connecting steel plate is not larger than the width of the connecting face of a rectangular concrete filled steel tubular column, the periphery of the connecting steel plate protrudes out of the end face of the box-type steel beam, holes are machined on the protruded periphery of the connecting steel plate, and the box-type steel beam is fixed at the design position of the rectangular concrete filled steel tubular column through the holes and rib-penetrated type high-strength bolts. The rectangular concrete filled steel tubular column and box-type steel beam rib-penetrated type node structure is simple in node structure and convenient in site, steel products are saved, and the bending moment and axial force of the structure are effectively transferred through the rib-penetrated type high-strength bolts, so that the structure is integral and is not integrally damaged on account of damaged nodes during earthquake, and the 'strong nodes and weak structure' design concept is achieved.
Description
Technical field
The utility model belongs to building engineering field, relates to a kind of Steel concrete combining structure.
Background technology
In recent years, high building structure begins application at home with the frame structure system that rectangular steel-tube concrete column and girder steel form.The rectangular steel-tube concrete column frame construction both can have been improved the two-way performance of frame construction, improved lateral rigidity and the stability of steel structure frame, and the rapid buckling failure of cylinder when preventing structural deterioration can strengthen again the fireproof performance of structure.Encased structures is combined into an integral body to steel and concrete bi-material, and bi-material is brought out one's strengths to make up for one's weaknesses, and has strengthened the local stability of steel pipe, has improved concrete intensity.Concrete-filled rectangular steel tube-steel framed structure can satisfy the demand of building flexible topology, and larger architectural space is provided, and satisfies various functional requirements, also can consist of and enrich changeable facade moulding, has higher whole mechanical property and anti-seismic performance.
At present, in concrete-filled rectangular steel tube-steel framed structure, girder steel is take I shape and H shaped steel as main, the employing steel beam with box shape that has, steel beam with box shape is multiplex in large-span structure and bridge construction, and steel beam with box shape can bring into play in the frame-generic structure that its bearing capacity is high, stress performance is good, the advantage of section form comparison rule.The node of steel beam with box shape adopts the form of construction work of Site Welding mostly, and steel beam with box shape is welded on the rectangular steel pipe.Welding manner 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 steel beam with box shape through ribbed node structure to be provided.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of rectangular steel-tube concrete column and steel beam with box shape through ribbed node structure, it is characterized in that, it is that end face at steel beam with box shape is welded with junction steel plate in advance, the width of junction steel plate should be not more than the joint face width of rectangular steel-tube concrete column, and junction steel plate around should stretch out beyond the steel beam with box shape end face, junction steel plate stretch out around be processed with some holes, steel beam with box shape is fixed on the design attitude of rectangular steel-tube concrete column with the through ribbed high-strength bolt by the hole.
For guaranteeing workmanship, when being welded to connect steel plate, fillet weld all around should guarantee firm welding.
Compared with prior art, the utlity model has following advantage:
1, because junction steel plate can be welded on the steel beam with box shape end in advance in factory, become an integrated member, site operation only need to carry out the connection of bolt so that on-the-spot construction it is convenient and simple, avoided construction trouble and the welding stress adverse effect of Site Welding.
2, be connected with rectangular steel-tube concrete column by 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; And the through ribbed high-strength bolt more is conducive to manage building of inner concrete and closely knit than internal partition in rectangular steel pipe.
3, the steel beam with box shape bearing capacity is high, stress performance is good, while section form comparison rule (than H shaped steel), and the later stage finishing is more convenient.
In a word, this joint structure is simple, and is on-the-spot convenient, save steel, by the moment of flexure between the effective transferring structure of through ribbed high-strength bolt and axle power, make structure have more globality, when earthquake, can not cause because of the destruction of node the integral body of structure to be destroyed, realize the design concept of " the weak structure of strong joint ".
With reference to the accompanying drawings, the utility model is described in further detail:
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 steel beam with box shape;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is top view of the present utility model, shows among the figure that rectangular steel-tube concrete column is provided with steel beam with box shape on four sides.
Marginal data, 1-rectangular steel-tube concrete column, 2-steel beam with box shape, 3-junction steel plate, 4-through ribbed high-strength bolt, 5-fillet weld.
The specific embodiment
As Figure 1-3, node structure of the present utility model, that end face at steel beam with box shape 2 is welded with junction steel plate 3 in advance, the width of junction steel plate 3 should be not more than the joint face width of rectangular steel-tube concrete column 1, and junction steel plate 3 around should stretch out beyond steel beam with box shape 2 end faces, junction steel plate 3 stretch out around be processed with some holes, steel beam with box shape 2 is fixed on the design attitude of rectangular steel-tube concrete column 1 with through ribbed high-strength bolt 4 by the hole.
For guaranteeing workmanship, when being welded to connect steel plate 3, fillet weld 5 all around should guarantee firm welding.
Claims (1)
1. a rectangular steel-tube concrete column and steel beam with box shape through ribbed node structure, it is characterized in that, it is that end face at steel beam with box shape is welded with junction steel plate in advance, the width of junction steel plate should be not more than the joint face width of rectangular steel-tube concrete column, and junction steel plate around should stretch out beyond the steel beam with box shape end face, junction steel plate stretch out around process porosely, steel beam with box shape is fixed on the design attitude of rectangular steel-tube concrete column with the through ribbed high-strength bolt by the hole.
