Description
Invention field
The present invention relates to the Structural Engineering field in civil engineering, particularly to a kind of to wearing steel-concrete group frame and the construction method that bolt type connects.
Background technology
The advantages such as steel-concrete combined structure takes full advantage of steel and the loading characteristic of concrete bi-material, therefore has mechanical property good, easy construction.Conventional steel-concrete combined structure has steel-concrete composite beam, steel reinforced concrete, concrete filled steel tube, steel reinforced concrete etc..Steel tube concrete superposed column is on the basis of traditional steel core concrete column, and one layer of armored concrete of outsourcing forms.Interior steel pipe column and the outer concrete of pipe can be circular, square or other cross-sectional shape.This class A of geometric unitA has the features such as bearing capacity is high, fire protecting performance is good, it is adaptable to major diameter post and other coupled columns bearing capacity in bridge pier and skyscraper require higher structure.
In existing frame structure, steel tube concrete superposed column generally links together with reinforced beam or girder steel.In framework, the design of steel tube concrete superposed column-steel beam connecting joint is the key link of this class framework, directly influences integral rigidity and the stress performance of structure, is also related to construction speed and the cost of structure entirety simultaneously.Traditional framework typically uses outer ring plate and connection with inner diaphragm, is coupled together by welding manner and girder steel, and this needs substantial amounts of welding job amount.Additionally, outer ring plate and arranging of internal partition can affect the cast of concrete inside and outside pipe, difficulty of construction is big, and progress is slower.Accordingly, it would be desirable to a kind of power transmission is clear and definite, functional and node type of attachment easily of constructing, so that the structural system that this rigidity of steel tube concrete superposed framework is big, fire resistance is good is widely applied in engineering.
Summary of the invention
It is an object of the invention to provide a kind of to wearing bolted steel-concrete group frame and construction method, it is characterized in that, described to wearing bolted steel-concrete group frame by steel tube concrete superposed column 1 and girder steel 2 being connected wearing bolt 9, formed multiple to wearing bolt connection node 3；In interior steel pipe column 4 periphery, vertical levelling dividing plate 12 welds with vertical levelling dividing plate 12 against interior steel pipe column outer wall, end plate 7 side, and opposite side is connected with girder steel 2；Stirrup 11 becomes peripheral steel reinforcement cage 8 with the colligation of vertical muscle 10；Manage outer formwork 13 to be supported on outside peripheral steel reinforcement cage 8, formed in Concrete Filled formwork 13 outside and manage outer concrete layer 6；Pipe inner core concrete 5 is filled in interior steel pipe column 4.
Described to wearing bolt connection node part, described to wearing bolt 9 screw rod through end plate 7 and the reserved hole of interior steel pipe column 4, and at two nut screwing clamping；By linking together to wearing the bolt 9 interior steel pipe column 4 by the end plate 7 welded with vertical levelling dividing plate 12 and steel tube concrete superposed column 1, thus realize girder steel 2 and the connection of steel tube concrete superposed column 1, transmission major part axle power, shearing and moment of flexure.
The construction method of described steel-concrete group frame, to each floor, first lifting superposed column internal steel tubing string and girder steel, by to wearing after bolt connects, intrusion pipe inner core concrete 5, muscle 10 is indulged in colligation periphery and stirrup 11 forms peripheral steel reinforcement cage 8, manages outer formwork 13 and is supported on outside peripheral steel reinforcement cage 8, and the outer concrete layer 6 of gate spool, complete this layer of construction；Pouring into a mould after due to steel tube concrete superposed column peripheral concrete being, the construction of upper floors steel construction part can be carried out with the construction of lower floor concrete parts simultaneously, thus is effectively improved efficiency of construction, it is achieved framework rapid construction.
Described it is through whole steel tube section to wearing bolt.
Described interior steel pipe column cross section is square or circular.
The outer concrete layer cross section of described pipe is square or circular.
Described girder steel is steel I-beam, steel box-girder, steel truss or jointing, and it is welding or bolt connection with the connection of end board assembly.
Described is plain bolt or friction-type bolt to wearing bolt.
Concrete construction method is as follows:
(1) reserved good hole on interior steel pipe column, lifts in place；
(2) connection is had the steel beam lifting of end board assembly to the position specified, with to wearing bolt through the hole on end plate and interior steel pipe column；
(3) two nut screwing clamping is to wearing bolt so that it is is connected with interior steel pipe column member in tight, completes connection procedure, afterwards steel pipe column inner core concrete in cast, colligation periphery steel reinforcement cage, the outer concrete layer of gate spool, completes a floor construction；
(4) lower floor concrete construction is carried out with upper floors Construction of Steel Structure simultaneously, it is achieved framework rapid construction；
The described side at interior steel pipe column or offside are provided with vertical levelling dividing plate (12)；To adapt to the alignment on steel pipe column surface in the inner circular of node area, if interior steel pipe column is square-section, vertical levelling dividing plate can be not provided with.
The invention has the beneficial effects as follows the deficiency overcoming existing steel-concrete group frame, such frame stiffness is big, bearing capacity is high, fire resistance is good, its node power transmission clearly, dependable performance and easy construction.Meanwhile, the construction organization of this class framework is efficiently, quickly, it is adaptable to have certain requirements engineering structure to the engineering time.This analogous frame structure uses be applicable to skyscraper.Have a characteristic that
(1) node connection aspect, or internal partition formula board-like with traditional outer annular-stiffer connects node and compares, use and need not or have only to little Site Welding workload to wearing bolted node, only need on steel pipe reserving hole, easy to process, reduce the impact such as welding processing workload and residual deformation；Owing to there is no the setting of ring flat-plate or dividing plate, facilitate in pipe, manage the cast of outer concrete.
(2) moment of flexure, axle power and shearing can effectively be undertaken to wearing bolt connection node, it is possible to need to be designed to just to connect according to difference, semi-rigid joint or hinged joint.Node force-transmission mechanism is: can the axle power on girder steel be delivered on steel tube concrete superposed column by end plate with to wearing bolt；By upper and lower row, the moment of flexure on girder steel can be delivered on steel tube concrete superposed column by the layout wearing bolt；By to wear bolt can be by the most of Shear transfer on girder steel to core concrete filled steel tube, on a part of Shear transfer to peripheral concrete.
(3) use at the construction field (site) manually to tighten and can realize steel tube concrete superposed column-steel beam joint and connect wearing bolt, installment work simple and fast, it is suitable for general job site or wild environment construction；Utilizing the feature of superposed column, can pour into a mould concrete in lower floor while upper strata sets up steel construction, upper and lower floor can be constructed simultaneously, improves efficiency of construction, shortens construction period.
