The component is allowwed to this node, and the bolt consolidation service is only carried out at the scene in that the mill is prefabricated, the bolted connection position is surperficial at the post, therefore does not influence the service function of structure, thickness that can be through the inside cross slab of adjusting bolt arrangement form, bolt specification, end plate thickness, column wall plate thickness, box post and other plates of putting more energy into and arrange bearing capacity, rigidity and the surrender mode of adjusting the node improves the ductility and the deformability of node.
Description
Technical field
Invention of the present utility model belongs to Structural Engineering long strands field, particularly relates to the prefabricated assembled high ductility bean column node of box column-I-beam.
Background technology
Along with society and expanding economy, more and more higher to the requirement of structural seismic performance in the design and construction of steel work, shorter and shorter to the requirement of construction period.Box column is column section type important in steel work, and the performance difference due to its strong axle and weak axle is less or do not have difference, and in the steel work that shockproof requirements is higher, application is more and more.I-beam is a kind of section forms of beam the most frequently used in steel work.Connection between current box column and I-beam mainly adopts Site Welding, and installation rate is comparatively slow, and the anti-seismic performance of node is very large by Site Welding quality influence; During mode with bolts, because box column generally can not be directly with bolts between post jamb plate and other plates, usual needs weld short beam in advance on post, short beam is connected with I-beam, link position need leave post surface certain distance, can affect the using function of structure to a certain extent.Between box column with I-beam, how directly carrying out quick, reliable bolt be connected when not affecting structure using function, is a problem urgently to be resolved hurrily in engineering reality.
Summary of the invention
Be connected this problem for how directly carrying out quick, reliable bolt between box column with I-beam, invention of the present utility model provides the prefabricated assembled high ductility bean column node of a kind of box column-I-beam.This node allows component to be prefabricated in the factory, and job site only need be carried out bolt consolidation service and not need welding, and can provide good ductility and deformability.
Bean column node provided by the invention comprises: I-beam, is made up of the edge of a wing and web, and end is with end plate, and box column, and it has four blocks of post jamb plates; Described end plate is bolted with corresponding described post jamb plate; Wherein said end welds described end plate in advance, and described end plate adopts concordant formula, one end extending type or two ends extending type
Box column inside is provided with multiple bolt hole, at the respective correspondence position welded sleeve in advance of described bolt hole, and in described sleeve, places bolt be in advance used for connecting described end plate and described post jamb plate.During on-the-spot splicing, bolt extracts rear mounting nuts out by the bolt hole on post jamb plate and end plate in sleeve.
Described box column can adopt welding box column, also can adopt rolling or cold forming box column.The inside of box column can adopt or not adopt the plate of putting more energy into of diaphragm and other arrangements as required.
When described box column adopts welding box column, first by bolt arrangement in sleeve, put more energy into by other except diaphragm plate, the sleeve that is furnished with bolt welds with corresponding post jamb plate, then wherein flute profile will be welded as by three blocks of post jamb plates, carry out welding of three post jamb plates of diaphragm and flute profile, and then welding a last post jamb plate, a last post jamb plate welds with adopting electroslag welding with consumable nozzle between diaphragm.
When described box column adopts rolling or cold forming box column, a kind of technical scheme is the mouth that punches on one of four blocks of post jamb plates, pass through that punched mouth completes that post internal-flange bolt is arranged, the welding of plate of putting more energy into of sleeve weld and diaphragm welding and other arrangements, then welding steel is by hole completion; Another kind of technical scheme is, box column is blocked in position, the welding of the plate of putting more energy into of the welding of the bolt arrangement of post inside, sleeve weld and diaphragm and other arrangements is completed, finally again by each truncation part welding splicing of box column by fracture.
Described end plate can adopt concordant formula, one end extending type or two ends extending type as required; When described end plate adopts one end extending type or two ends extending type, end plate sponson can adopt as required or not adopt stiffening rib.
Beneficial effect: (1) beam, post component can be prefabricated in the factory, scene only needs carry out bolt splicing and do not need to weld, and is convenient to rapid construction and avoids the adverse effect of weld defect to Seismic Behavior;
(2) end plate is directly bolted with the post edge of a wing, avoids and carry out the impact of bolt connection on structure using function in the middle of beam;
(3) sleeve can ensure that in transport and installation process, bolt can not come off;
(4) bearing capacity of knot modification, rigidity and surrender pattern can be come by the thickness and layout adjusting bolt arrangement mode, bolt specification, end plate thickness, post jamb plate thickness, the inner diaphragm of box column and other plates of putting more energy into, improve deformability and the ductility of node.
