Abstract

The invention relates to a steel structure building beam or a steel structure pillar node interface, which is used for connecting convergent nodes of a steel structure building beam or a steel structure pillar and overcoming the shortages of toilsome assembly, bad accuracy, low connection strength, and the like in the existing connection mode. The steel structure building beam or pillar node interface is composed of joints of the end part of the beam or the pillar and joint seats converged on the node, wherein the joints lack a half at the end part in the horizontal direction to form a ladder shape. The shape and the size of the joint seats are the same with that of the joints. A connection insertion tenon is arranged on a mutual faying surface formed when the joint is butt jointed with the joint seat, the connection insertion tenon is vertical to the faying surface and a fastening structure for preventing the joint and the joint seat from horizontally separating is arranged at the faying position of the joint and the joint seat. According to invention, the steel structure building beam or pillar node interface has the beneficial effects that the faying mode bearing of the interface has large bearing capacity; the steel structure building beam-pillar node interface has high longitudinal tensile strength, is provided with the fastening member for preventing the joint and the joint seat from horizontally separating so that the connection of the node of the beam and the pillar has multi-directional higher anti-breaking strength, has a simple structure, and is convenient to manufacture and install; and with the adoption of the steel structure building beam or pillar node interface, the conditions are created for modularization, standardization and serialization of steel structure housing construction.

Description

A kind of steel construction beam, post node interface

Technical field

The invention belongs to building unit, be specifically related to the connection of a kind of steel construction beam, post at the node place.

Background technology

In the past, mostly adopted building site welding, rivet or bolton ways of connecting at steel construction beam, post in the connection at node place.Adopt field Welding, when welding, member suspention, stability of strutting system accuracy require high; Cooling is fast in the welding, distortion is big; The commissure is prone to form big stress, many reduction strength factors such as the commissure structure is inhomogeneous, material embrittlement, and safety descends; Anti-seismic performance is low, and construction cost is high.Though riveted joint is connected member tie point structure with bolt and does not become; But because of contact riveting (spiral shell) nail consumption many; The workload of member preprocessing is big, and a fairly large number of nail hole makes beam, styletable head weakening strength, and is also not easy to operate during assembling; The accuracy of influence assembling, tubular member are inappropriate for drift bolt and connect.

Summary of the invention

The purpose of this invention is to provide a kind of steel construction beam, post node interface, be used for steel structure building beam, the connection of post aggregation node, the assembling effort, the accuracy that overcome existing welding, riveted joint, bolton connection existence are poor, the low deficiency that waits of bonding strength.

Beam of the present invention, post node interface are made up of the joint of beam or column end and the plinth that collects on the node, and joint wherein lacks half and forms stepped in end cross.The shape of plinth, size are identical with joint.The plug tenon that is connected that vertical faying surface is arranged on the mutual faying surface that when joint docks with plinth, forms, joint with plinth lap-joint the fastening hoop that prevents joint and plinth lateral separation is arranged or penetrate joint and the fastening bolt of plinth or through the trip bolt of joint or plinth screw-in plug tenon or embed respectively joint and plinth two not the interface place on same cross section stretch into the fastening key in the interface side pieces.More than be basic scheme of the present invention.

On joint wherein and the plinth faying surface vertical faying surface be connected plug tenon, can be that plug tenon hole, plug tenon are all arranged on joint and the plinth is the form of independent member.Also can be that plug tenon and joint or plinth are integral, the form of establishing mortise on plinth relative or the joint with the joint that has plug tenon or plinth.Employed plug tenon is first-selected with the taper shape.

Use in the structure of fastening key at the interface place; Forming the gap around the fastening key key when preventing that interface is out of shape by extraordinary active force pitches fastening key; Be equipped with at interface and cover fastening key, prevent that the coaming plate that it comes off from interface, this coaming plate from comprising that two relative faces of three faces of cross section rectangle cover the side that joint and plinth have overlapping the slot.Coaming plate is screwed at interface.

In the structure of using fastening hoop; Fastening hoop select for use by the reinforcing steel bar frame on three limits of rectangle, reinforcing steel bar frame seal baffle plate, fastening nut is formed; There is one section screw thread the end of reinforcing steel bar frame open side reinforcing bar; Fastening nut is joined on the screw thread of the steel bar end in the hush panel outside in the end reinforced hole of passing the hush panel two ends.

Collect in the quantity and the orientation of the plinth on the node among the present invention, depend on the quantity and the relative space position relation of beam, post.Be integrated into a plurality of plinths of one, with the technology mode formation of casting or welding in advance, adopting the technological process of the mode of welding is first welding node case; On the tank wall of node case, weld each plinth again, after welding is accomplished, as required; Can carry out bulk heat treatmet; To eliminate the stress of commissure, improve the structure of commissure, eliminate fragility.

Good effect of the present invention is: the interface overlapping carries, and bearing capacity is big.With horizontal feather joint joint and plinth; The interface endwise tensile strength is high; Be equipped with the clamp structure that prevents joint and plinth lateral separation, make beam, the connection of post have multidirectional higher resistance of failure, particularly on two parts interface, embed the structure that is connected key at the node place; Can not only obtain the enough big anti-joint and the shear strength of plinth lateral separation, and simple in structure, especially also very convenient.Gather several plinths, be convenient to moulding in node, when particularly adopting welding fabrication, than beam, post directly in the building site welding precision much higher, can also heat-treat in case of necessity to eliminate the stress and the fragility of weld seam, guarantee needed intensity.Adopt steel structure girder of the present invention, post node interface, make that assembling combination is convenient and swift at the node place between beam, the post, intensity is high, for condition has been created in modularization, standardization, the seriation of building steel structure house.
