Abstract

The utility model discloses a full assembled steel structure node suitable for beam column is H shaped steel altogether, including H shaped steel post, H shaped steel roof beam, pi shape steel connecting piece and bolt, the roof beam of two directions of this node strong axle, weak axle all is through pi shape steel connecting piece and column connection, pi shape steel connecting piece has increased node rigidity, and the work progress only needs the bolt, does not need the welding completely. The invention is suitable for the fully assembled steel structure node with H-shaped steel beams and columns, has simple structure, direct force transmission and high node rigidity, and achieves the effect of outward movement of the beam end plastic hinge at the beam column node under the action of horizontal earthquake.

Description

Full-assembly type steel structure node suitable for beam column is H shaped steel
Technical Field
The utility model relates to an assembly type structure manufacturing field, concretely relates to full assembly type steel construction node suitable for beam column is H shaped steel.
Background
Traditional beam column connected node is mostly all-welded or partial welding form, but welded node ductility is poor, especially under the earthquake action, takes place brittle failure easily, and there is a large amount of welding work in the job site, has influenced construction speed and quality greatly, is not suitable for assembled steel structure, simultaneously because welding area is big, produces great residual stress easily, influences the atress performance of node. In order to accord with the design concept of 'strong column and weak beam, strong node and weak member' in the anti-seismic design, domestic and foreign scholars propose to reinforce beam-column nodes by additionally arranging a strength rib, a cover plate, beam armpits and the like at beam ends, but the method increases the welding workload.
The partially assembled steel structure node adopts a cantilever short beam type beam column connecting node, the welding quality of the beam column joint is improved by the partially assembled steel structure node, and the transportation difficulty is increased.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is guaranteeing to connect the position and has enough intensity, rigidity and ductility, by keeping the time of the exact mutual position between the connecting elements, guarantees installation simple accurate, does not have on-the-spot welding work load completely, improves on-the-spot assembly efficiency one kind and is applicable to the full assembled steel structure node that the beam column is H shaped steel, and it can solve the problem that exists in the background art effectively.
The utility model aims at adopting the following technical scheme to realize: the utility model provides a full assembled steel construction node suitable for beam column is H shaped steel, including H shaped steel post, H shaped steel roof beam, pi shaped steel connecting piece and bolt, the strong axle of this node, the H shaped steel roof beam of two directions of weak axle all is connected with H shaped steel post through pi shaped steel connecting piece, pi shaped steel connecting piece comprises a vertical bottom plate, two diaphragms and two short risers, two diaphragms are connected perpendicularly in the bottom plate, clear distance between two diaphragms is greater than the section height of H shaped steel roof beam slightly, be equipped with two short risers in the middle of two diaphragms, two short risers are connected perpendicularly in the bottom plate, distance between two risers is greater than the web thickness of H shaped steel roof beam slightly.
Preferably, the number of the H-shaped steel beams and the n-shaped steel connecting pieces is two, the two n-shaped steel connecting pieces are respectively connected to a web plate and a wing plate of the H-shaped steel column through bolts, an upper wing plate and a lower wing plate at one end of each H-shaped steel beam are respectively located on the inner sides of an upper transverse plate and a lower transverse plate of each n-shaped steel connecting piece and are connected through bolts, and the end portion of the web plate of each H-shaped steel beam is located between two short vertical plates of each n-shaped steel connecting piece and is.
Preferably, the n-shaped steel connecting piece is of an integrated structure.
Owing to adopted above technical scheme, the utility model discloses following beneficial effect has: the structure is simple, the force transmission is direct, no welding work is needed, the node rigidity is high, and the effect that the beam end plastic hinge moves outwards at the beam-column node under the action of a horizontal earthquake is achieved.

Fig. 1 is the utility model is suitable for a beam column is the structural schematic of full assembled steel structure node of H shaped steel.
Fig. 2 is the utility model is suitable for a beam column is the exploded view of the full assembled steel structure node of H shaped steel.
In the drawing, the first is an H-shaped steel beam, the second is an n-shaped steel connecting piece, the third is an H-shaped steel column and the fourth is a bolt.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a full assembled steel structure node suitable for beam column is H shaped steel, including H shaped steel post (c), H shaped steel roof beam (c), pi shape steel connecting piece (c), bolt (c). The beams in the strong axis and the weak axis of the node are connected with the column through n-shaped steel connecting pieces, the rigidity of the node is increased through the n-shaped steel connecting pieces, and the node is only welded by bolts in the construction process. The utility model is suitable for a beam column is the full assembled steel structure node of H shaped steel, and the structure is simple and easy, pass power directness, and node rigidity is big, has reached the effect that the beam end plasticity hinge of beam column node department moved outward under the horizontal earthquake effect.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
