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 of steel work or frame structure building, post in the connected mode of Nodes that crosses.
Background technology
In the past, in the mode that steel construction beam, post mostly adopt building site welding, rivet or bolton to connect in the connection of Nodes.Employing scene is directly welded to connect.Directly be welded to connect, there is component suspention, supporting & stablizing difficulty, in installation, accuracy is poor, existence is uncertain, in welding, cooling is fast, distortion is large, commissure easily forms larger stress, many reduction strength factors such as commissure structure is uneven, material embrittlement, and safety declines, anti-seismic performance is low, and construction cost is high.Although riveted joint is connected component tie point structure with bolt and does not become, because of contact riveting (spiral shell), to follow closely consumption many, and the workload of component preprocessing is large.Meanwhile, a fairly large number of nail makes beam, post main part of the force weakening strength, also not easy to operate during assembling, the accuracy of impact assembling, and tubular member is unsuitable for drift bolt and connects.Before this, the applicant of the application once proposed to overlap and was aided with the beam of the Nodes of anticreep component, post connected mode, but still it is large to there is material usage, in not easily making and making restive distortion deficiency.
Summary of the invention
The object of this invention is to provide a kind of prefabricated high-strength building thing beam, column node member, beam, the connection of post aggregation node of building or other materials frame structure building is built for steel, overcome existing welding, riveted joint, that bolton connects the assembling effort, the accuracy that exist is poor, bonding strength is low waits deficiency.
Prefabricated high-strength building thing beam of the present invention, column node member, by the prefabricated lapping to beam, styletable, collect each lapping in the set joint of node and anti-detachment connecting elements composition;
Lapping wherein comprises tenon seat, be welded on tenon seat towards node side lapped tenons, be welded on the plug tenon of tenon seat towards beam or post side, the end face of tenon seat welded lap tenon has lapped tenons to locate fin, lapped tenons by coincide on the fin of location and the inboard plate welded with tenon seat, outer panel, be welded on the arch between inboard plate and outer panel fagging, be welded on inboard plate and become with the butt end head group that plate end is pulled in outside, lapped tenons accounts for tenon seat end face half area.The centre bit of lapped tenons is equipped with the anti-detachment bolt hole of through inboard plate and outer panel, is be welded on steel mesh reinforcement on tenon seat or shaped steel and armor Plate or steel mesh reinforcement and shaped steel and armor Plate and use towards the plug tenon of beam or post side in lapping;
Set joint wherein by regular hexahedron multi-faceted node tenon seat, to be welded on node tenon seat required orientation and respectively to carry tenon and form, node tenon seat is identical with the tenon seat end face structure of welded lap tenon in the lapping for beam, styletable for the end face welding carrying tenon, and the carrying tenon on set joint is identical with the lapped tenons structure in beam, post lapping;
The annexation of the lapping of set joint and beam, styletable is: the lapped tenons of beam upper, gather carrying tenon on joint under, the inboard plate of lapped tenons and the inboard plate that carry tenon fit, lapped tenons and carry anti-detachment bolt hole in the middle part of tenon and pass the bolt that prevention is separated from each other.Be more than basic scheme of the present invention.
Be fastenedly connected for being formed between tenon and the tenon seating face docked, prevent shearing force suffered by lock(ing) bolt excessive to improve lapping with the set assembly precision of joint and moment of resistance performance, the docking termination of lapped tenons and the docking termination of carrying tenon all form the part of stretching out outer panel external surface, row's screw rod perforation is separated in this portion, the tenon seat end face relative with the butt joint of tenon is opened the screwed hole coincide with the screw perforation in the butt joint of tenon, with row's screw, the docking termination of tenon is fastened on relative tenon seat.
For sharing the active force between lapped tenons and carrying tenon, keyway is had in the centre position of lapped tenons docking termination and carrying tenon docking termination, the tenon seat end face relative with the butt joint of tenon drives the keyway relative with the keyway in the butt joint of tenon, sunk key in the dowel hole that the keyway on the keyway in the butt joint of tenon and tenon seat surrounds.
For the beam, the post that improve use the present invention connection further have higher assembly precision, avoid the generation of the mount stress affecting building safety, node tenon seat in the present invention processes the carrying tenon tenon seat end face of required face number by the square body bloom of monoblock, the lightening hole be drilled in the face by remainder is had in tenon seat, for the node tenon seat of needs six tenon seat end faces, the tenon seat end face being processed five carrying tenons by the square body bloom of monoblock is formed with the 6th tenon seat end face be welded in the plane of a remaining drill-through lightening hole.
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 easily controls, adjust, and the final lapping that formed and set joint geometry, size specification, beam, post are high at the assembly precision of Nodes, bearing capacity large, highly versatile.Achieve prefabricated, the simply-assembled form of construction work in job site of connecting elements batch production at beam, Column border node place, production efficiency is high.Active force between lapped tenons and carrying tenon is broken up, is avoided local overload.After assembling, member stress is even gently, and connected node bulk strength is large.
