Abstract
A precast high-strength building beam and column node component is used for connection of steel structure building beam and column nodes, and overcomes the defects that labor is wasted, accuracy is poor, and intensity is low in existing connecting methods. The precast high-strength building beam and column node component is composed of lap joints which are precast on the end of a beam and the end of a column, a collection joint collecting all the lap joints on a node and an anti-separation component. Each lap joint comprises a tenon seat, a lap tenon and an inserting tenon, each lap tenon is welded on one side, facing the node, of the corresponding tenon seat, each inserting tenon is welded on one side, facing the beam or the column, of the corresponding tenon seat, and each lap tenon is formed by an inner side plate, an outer side plate, an archy supporting plate and a butt joint end socket. The collection joint is composed of a regular hexahedron multidirectional node tenon seat and all bearing tenons in needed directions of the node tenon seat, the end face of the node tenon seat and the end face of the tenon seat in each lap joint are identical in structure, and the bearing tenons and the lap tenons are identical in structure. The precast high-strength building beam and column node component has the advantages that eventually formed lap joints and the collection joint are standard in shape and size, the beam and the column are high in assembly accuracy and large in intensity at the node position, and the high-efficiency construction mode that the connecting components of the node position of the beam and the column are precast in factories and assembled in construction sites simply and conveniently is achieved.
Description
Technical field
The invention belongs to building unit, be specifically related to the beam, post of steel work or frame structure building in the connected mode of Nodes that crosses.
Background technology
In the past, the mode that mostly adopted building site welding, rivet or bolton to connect at steel construction beam, post in the connection of Nodes.Employing scene is directly welded to connect.Directly be welded to connect, there is member suspention, supporting & stablizing difficulty, in installation, accuracy is poor, existence is uncertain, in welding cooling fast, distortion is large, commissure easily forms larger stress, many reduction strength factors such as commissure structure is inhomogeneous, material embrittlement, and safety declines, anti-seismic performance is low, and construction cost is high.Although riveted joint is connected member tie point structure and does not become with bolt, because contact riveting (spiral shell) nail consumption is many, the workload of member preprocessing is large.Meanwhile, a fairly large number of nail hole makes beam, the main part of the force of post weakening strength, also not easy to operate when assembling, the accuracy of impact assembling, and tubular member is unsuitable for drift bolt and connects.Before this, the application's applicant once proposed to overlap and be aided with beam, the post connected mode of the Nodes of anticreep member, but still existed material usage large, be difficult for make and make in restive distortion deficiency.
Summary of the invention
The object of this invention is to provide a kind of prefabricated high-strength building thing beam, post node component, beam, post aggregation node for steel structure building or other materials frame structure building connect, the assembling effort, the accuracy that overcome existing welding, riveted joint, bolton connection existence are poor, the low deficiency that waits of bonding strength.
Prefabricated high-strength building thing beam of the present invention, post node component, by the prefabricated lapping to beam, styletable, collect each lapping in set joint and the anti-detachment connecting elements composition of node;
Lapping wherein comprises tenon seat, be welded on tenon seat towards the lapped tenons of node one side, be welded on the plug tenon of tenon seat towards beam or post one side, the end face of tenon seat welded lap tenon has lapped tenons location fin, lapped tenons by coincide on the fin of location and with inboard plate, the outer panel of tenon seat welding, be welded on the arch between inboard plate and outer panel fagging, be welded on inboard plate and outside and pull the termination of docking of plate end and form, lapped tenons accounts for tenon seat end face half area.The centre bit of lapped tenons is equipped with the anti-detachment bolt hole that connects inboard plate and outer panel, in lapping, is be welded on steel mesh reinforcement or shaped steel and armor Plate or steel mesh reinforcement and shaped steel and the armor Plate on tenon seat and use towards the plug tenon of beam or post one side;
Set joint wherein by the multi-faceted node tenon of regular hexahedron seat, be welded on node tenon seat required orientation and respectively carry tenon and form, node tenon seat is identical with the tenon seat end face structure of the lapping welded lap tenon for beam, styletable for welding the end face of carrying tenon, gather carrying tenon on joint with beam, post lapping on lapped tenons structure identical;
The annexation of the lapping of set joint and beam, styletable is: the carrying tenon of the lapped tenons of beam on upper, set joint under, the inboard plate of lapped tenons and the inboard plate of carrying tenon fit, the bolt that the anti-detachment bolt hole of lapped tenons and carrying tenon middle part is separated from each other through prevention.Be more than basic scheme of the present invention.
For being fastenedly connected forming between tenon and the tenon seating face docking, to improve lapping and gather assembly precision and the moment of resistance performance of joint and prevent that the suffered shearing force of lock(ing) bolt is excessive, the docking termination of the docking termination of lapped tenons and carrying tenon all forms the part of stretching out outer panel external surface, in the separately row's screw rod perforation of this, on the tenon seat end face relative with the butt joint of tenon, open with the butt joint of tenon on the identical screwed hole of screw perforation, the docking termination of tenon is fastened on relative tenon seat with row's screw.
For sharing the active force between lapped tenons and carrying tenon, centre position in lapped tenons docking termination and carrying tenon docking termination has keyway, on the tenon seat end face relative with the butt joint of tenon, open with the butt joint of tenon on the relative keyway of keyway, sunk key in the dowel hole that the keyway on the keyway in the butt joint of tenon and tenon seat surrounds.
There is higher assembly precision for further improving the beam, the post that use the present invention to connect, avoid the generation of the installation stress that affects building safety, node tenon seat in the present invention is processed the carrying tenon tenon seat end face of required number by the square body bloom of monoblock, in tenon seat, there is the lightening hole being drilled to by remaining face, for the node tenon seat of six tenon seat end faces of needs, process the tenon seat end face of five carrying tenons and the 6th tenon seat end face that is welded in a remaining plane of boring lightening hole forms by the square body bloom of monoblock.
Good effect of the present invention is: tenon seat monoblock machining, precision is guaranteed.Lapped tenons and carrying tenon all piecewise (part) weld on tenon seat, and accuracy is easily controlled, adjusted, the final lapping forming and set joint geometry, size standard, and beam, post is high at the assembly precision of Nodes, bearing capacity large, highly versatile.The connecting elements batch production that realized beam, post Nodes is prefabricated, job site simply-assembled form of construction work, and production efficiency is high.Active force between lapped tenons and carrying tenon is broken up, avoided local overload.After assembling, member stress is even gently, and connected node bulk strength is large.
