The utility model relates to a steel channel web inserted type connection joint structure between steel girders and a square concrete-filled steel-tubular column and belongs to the field of the building structure engineering technology. The connection joint structure is formed by the square concrete-filled steel-tubular column, the steel girders, steel channels, horizontal connecting plates and vertical connecting plates. Vertical grooves are formed in the positions, located on the wallboard of the square concrete-filled steel-tubular column, of steel channel webs, the size of the vertical grooves are the same as the size of the steel channel webs, and the vertical grooves are used as channels through which the steel channel webs are inserted into the square concrete-filled steel-tubular column. Two flanges of each steel channel and the upper flange and the lower flange of each steel girder are located on the same horizontal plane. The two flanges and the webs are directly welded to the wallboard of the square concrete-filled steel-tubular column respectively. The height of the steel channels is the same as that of the steel girders. The connection joint structure is simple, convenient to manufacture and install, and clear and reliable in force transmission and adapts to industrial production requirements.
Description
Technical field
The utility model belongs to building engineering field, relates to a kind of concrete-filled steel square tubular column of channel-section steel web interpolation type and the connecting joint structure of girder steel.
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.Wherein external partition formula, internal partition formula respectively have advantage, also Shortcomings; External partition has been inherited self and has been connected simple feature with girder steel, and internal partition can effectively transmit pulling force and the pressure of bottom flange on girder steel; Because internal partition and external partition are independently used, can not well transmit beam-ends pulling force.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 is more concentrated, and in China, application is less.Develop a kind of novel connected node form and become objective demand.
Utility model content
The purpose of this utility model is to provide a kind of concrete-filled steel square tubular column of novel channel-section steel web interpolation type and the connecting joint structure of girder steel, overcomes the technological deficiency that in prior art, concrete-filled steel square tubular column and steel beam joint exist.
For achieving the above object, solution of the present utility model is:
The concrete-filled steel square tubular column of novel channel-section steel web interpolation type and a connected node for girder steel, be comprised of concrete-filled steel square tubular column, girder steel, channel-section steel, level and vertical junction plate, is a kind of simple structure, and power transmission is clear and definite, the simple novel joint form of constructing.Described concrete-filled steel square tubular column comprises the concrete of square steel pipe and inner perfusion; Described girder steel comprises bottom flange and web, and described U-steel comprises two edges of a wing and web; Two edges of a wing of U-steel and the upper bottom flange of girder steel are on same horizontal plane; The upper bottom flange of girder steel is connected with high-strength bolt with two edges of a wing of channel-section steel by horizontal connecting plate; The web of girder steel is connected with high-strength bolt with square steel pipe by vertical junction plate; Two edges of a wing of U-steel and web are directly welded on the wall of square steel pipe; Two edges of a wing of U-steel and the upper bottom flange of girder steel are on same horizontal plane; In the web of U-steel, insert concrete-filled steel square tubular column.
The section form of described steel core concrete column is square; Described girder steel is H section steel beam, comprises hot rolling type H section steel beam or welded H section steel beam.Described concrete is ordinary concrete, high-strength concrete or self-compacting concrete.
Owing to adopting such scheme, the utlity model has following useful technique effect:
The utility model node structure simple structure, processes easy for installationly, and power transmission is clearly reliable, has adapted to suitability for industrialized production demand.
The utility model node and the comparison of internal partition formula node, have good stress performance, inserts concrete column in its U-steel web, further strengthened the stress performance of node, improved the ability of shear resistance and the bending resistance square of node.
The utility model node is compared with external partition formula node, and the connection between H section steel beam, reinforced concrete floor and concrete-filled steel square tubular column is more direct, has reduced the workload of construction welding.
Because the inside of concrete-filled steel square tubular column only has vertical web, be easy to concrete the watering of node region and smash, and can the concrete quality of guarantor's steel core concrete column internal node core space.
The utility model Joint design method is clearly reasonable, and construction sequence is simple.
