Description
Technical field
The utility model relates to building engineering field, especially relates to a kind of angle steel connecting-type rectangular steel-tube concrete column and girder steel through ribbed connected node.
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.Steel-concrete combined structure has been given full play to concrete and has been born pressure and the mechanical properties of materials of steel bearing tension, secondly, the application of steel also helps the heavy in section of crossing of reducing concrete structure, and concrete material can reduce in steel work fireproof requirement the strong effect of steel.In addition, combinations thereof structure also helps the improvement of anti-seismic performance.At present, steel-concrete combined structure is that steel-concrete combined structure is extensive in a lot of countries use, and domestic development is also rapider.
In steel-concrete combined structure, applying more is encased structures, so-called encased structures be exactly concrete is poured in steel pipe and tamping to add the strength and stiffness of big steel pipe.This structure has been given full play to the strong point of steel pipe and concrete bi-material, has that bearing capacity is high, plasticity and an advantage such as good toughness, easy construction, is widely used in the structures such as individual layer and multi storied industrial factory building post, highrise building and bridge.This year particularly, along with the promotion and application of steel structure of housing, the frame structure forming with steel core concrete column and girder steel ties up to and in engineering practice, is applied gradually and develops, and has obtained good economic benefit and social benefit.
At present, it is through that the connected node form of the concrete-filled steel square tubular column of China and girder steel mainly contains external partition formula, internal partition formula and dividing plate.The through node of its median septum requires concrete-filled steel square tubular column bottom flange correspondence position on girder steel to block, and diaphragm is welded in behind relevant position, again welds former square steel pipe.This node construction is complicated, and weld seam concentrates the application of ， China less
In the research of current China, through ribbed connected node form is mainly that bolt perforation overhanging end is board-like, and girder steel, by welded end plate or T-steel, is connected with post by the strength bolts of growing tall that connects shaft, until the concrete in pipe, reach after some strength, shank of bolt is applied to prestressing force.
Utility model content
Task of the present utility model is to solve the technological deficiency that in prior art, concrete-filled steel square tubular column and steel beam joint exist, and a kind of angle steel connecting-type rectangular steel-tube concrete column and girder steel through ribbed connected node are provided.
Its technical solution is:
Angle steel connecting-type rectangular steel-tube concrete column and a girder steel through ribbed connected node, consist of steel core concrete column 1, girder steel 3, angle steel 4 and through ribbed high-strength bolt 6; Described steel core concrete column is comprised of steel pipe 1 and the concrete 5 being filled in steel pipe 1, on girder steel 3, bottom flange is directly welded on the post jamb of steel core concrete column 1, girder steel 3 webs are connected by angle steel 4 use high-strength bolts 2 with steel core concrete column post jamb, the another side of angle steel 4 is welded on steel core concrete column post jamb, and reserving hole channel, is convenient to through ribbed high-strength bolt 6 and passes; On position corresponding to angle steel 4 preformed holes on steel core concrete column post jamb, have through hole, size matches with the reserved duct of angle steel 4, and described through hole runs through the passage of steel core concrete column wallboard as through ribbed high-strength bolt 6; Through ribbed high-strength bolt 6 will ensure enough prestressing force, and bolt head adopts double nut structure simultaneously.
In the utility model, the section form that described steel core concrete column is rectangle.
In the utility model, described girder steel 3 is i-shape steel beam.
In the utility model, described concrete be in ordinary concrete, high-strength concrete or self-compacting concrete any.
The utlity model has following useful technique effect:
The through ribbed high-strength bolt of the utility model node, its effect is equivalent to internal partition, can effectively transmit pulling force and the pressure of bottom flange on girder steel; Compare external partition joint form, there is the advantages such as power transmission is direct, saving steel, assurance architectural space.
The utility model node through ribbed high-strength bolt not only has the effect of internal partition, compares with internal partition simultaneously, pulling force that can more efficiently transmission girder steel; And through ribbed high-strength bolt is more conducive to manage building of inner concrete and closely knit than internal partition in rectangular steel pipe.
The utility model joint structure is simple, processes easy for installationly, and power transmission is clearly reliable, has adapted to suitability for industrialized production demand.
The utility model node is compared with external partition formula node, and the connection between girder steel, reinforced concrete floor and concrete-filled steel square tubular column is more direct, has reduced the workload of construction welding.
The utility model Joint design method is clearly reasonable, and construction sequence is simple.
