The invention belongs to the field of structural engineering in civil engineering, and in particular relates to an assembleable steel pipe concrete composite column-steel concrete beam joint. Holes are respectively set on the steel pipe and the end plate assembly welded with the section steel, and the unilateral bolts pass through the end plate assembly and the steel pipe in turn to connect the steel pipe and the section steel; and beam stirrups to form beam-column connection nodes; internal concrete is poured inside the steel pipe, external concrete is poured outside the steel pipe, and beam concrete is poured outside the section steel. The invention has the advantages of convenient on-site assembly, reliable performance, good earthquake resistance and fire resistance, and is suitable for multi-story, high-rise, super high-rise or other related engineering structures.
Description
Technical field
The invention belongs to the Structural Engineering field in the civil engineering, particularly be specifically related to a kind of combinable steel tube concrete superposed column-steel reinforced concrete girder connection.
Background technology
Steel core concrete column is the member that steel pipe and concrete filled combine, the steel duct concrete is subject to the effect of contraction of steel pipe, improved its supporting capacity, concrete existence has also restricted the inside buckling failure of steel pipe, and this structure is widely used in highrise building.Steel tube concrete superposed column is to be to grow up at the concrete filled steel tube patten, at concrete filled steel tube outer setting reinforcing bar, the new structural members that concreting forms, it not only has advantages of steel core concrete column, the concrete of steel pipe outside can delay the rising of steel beam columns under fire condition pipe temperature simultaneously, has improved the fire resistance of post.Adopt in the frame construction of steel tube concrete superposed column, the design of its beam-column connection directly has influence on the integral working of structure, also has influence on the working procedure of structure, is the key link of this class formation therefore.Outer annular-stiffer gusset-type joint commonly used is applied in and has certain problem in the steel tube concrete superposed column in the frame construction of employing steel core concrete column in the past, outer ring plate can affect the outside concrete of steel pipe, therefore the joint form of, dependable performance clear and definite in the urgent need to a kind of power transmission and easy construction.
Summary of the invention
The object of the present invention is to provide the beam-column connection of the employing steel tube concrete superposed column of a class easy construction.
The technical solution used in the present invention is:
Steel pipe and with the end board assembly of shaped steel welding on hole is set respectively, monolateral screw bolt passes end board assembly and steel pipe are connected steel pipe with shaped steel; The outside of steel pipe and shaped steel is the vertical muscle of colligation post, column tie-bar, the vertical muscle of beam and beam stirrup respectively; The inner concrete of cast in the steel pipe, steel pipe is poured into a mould outside concrete outward, and shaped steel is poured into a mould the beam concrete outward.
Described end board assembly is flush end plate or arc-shaped end plate.
The cross section of described steel pipe is square, rectangle or circle.
The transversal of described shaped steel is I shape or cross.
Beneficial effect of the present invention is:
(1) such connected node Path of Force Transfer is clear and definite, can effectively transmit or bear Shear force within the beam end and moment of flexure.Outside concrete can effectively be protected inner steel pipe, shaped steel and reinforcing bar under fire, delay the rising of steel temperature, improves the fire resistance of node.
(2) this category node does not need or only need factory's welding job amount seldom, only needs prepared screw-bolt hole hole on steel pipe and end board assembly, and is easy to process, avoided welding residual stress that Site Welding causes and the impact of weldquality.
(3) adopt monolateral bolt on-the-spot splicing steel pipe and shaped steel, can erect fast overall frame construction, convenient further reinforcing bar binding and concreting.
(4) its work progress has adopted factory's weldable steel parts, on-the-spot bolt assembly unit steel pipe and shaped steel to form the operation that steel frame, on-the-spot assembling reinforcement and concreting are finished node construction, the reliable steel tube concrete superposed column connected node of can providing convenience has advantages of that speed of application is fast, power transmission is clear and definite, fire resistance is good.

The invention provides a kind of assemble type steel tube concrete superposed column-steel reinforced concrete girder connection, below in conjunction with the embodiment of accompanying drawing structure of the present invention and the specific embodiment are further described.
Fig. 1 and Fig. 2 are the structural representation of the embodiment of the invention, and this node is comprised of steel tube concrete superposed column 1 and girder with rolled steel section en cased in concrete 2.In the structure of steel tube concrete superposed column 1, the cross section of steel pipe 3 is square, and end board assembly 9 is the flush end plate, and in the girder with rolled steel section en cased in concrete 2, shaped steel 6 is i iron; On steel pipe 3 and the end board assembly 9 hole is set respectively, monolateral bolt 8 passes end board assembly 9 and steel pipe 3 successively, and steel pipe 3 is connected connection with shaped steel; The outside of steel pipe 3 and shaped steel 6 is the vertical muscle 10 of colligation post, column tie-bar 11, the vertical muscle 12 of beam and beam stirrup 13 respectively; The inner concrete 4 of steel pipe 3 interior cast, the outside concrete 5 of steel pipe 3 outer cast, shaped steel 6 outer cast beam concrete sevens.
Concrete construction method of the present invention is as follows:
(1) with end board assembly 9 and shaped steel 6 welding;
(2) reserved hole at end board assembly 9 and steel pipe 3;
The shaped steel 6 that (3) will weld end board assembly 9 is lifted into steel pipe 3 reserving hole places, passes reserving hole on end board assembly 9 and the steel pipe 3 with monolateral bolt 8, and tights a bolt in end board assembly one side, end board assembly 9 is connected with steel pipe closely connects, and forms whole;
(4) the vertical muscle 10 of colligation reference column, column tie-bar 11, the vertical muscle 12 of beam and beam stirrup 13 are built steel duct concrete 4, the outside concrete 5 of steel pipe and beam concrete seven afterwards, finish node construction.
