Abstract
The utility model relates to a kind of linkage of not contour girder steel, comprises frange plate, direct-connected fishplate bar, inclined connection plate and haunch connected system.Frange plate is all adopted to carry out reinforcement of weld in the side of deep beam and shallow beam; On mullion between deep beam and shallow beam, its top adopts direct-connected fishplate bar to reinforce, and bottom adopts inclined connection plate to reinforce, or bottom adopts direct-connected fishplate bar and the haunch connected system between outside and shallow beam jointly to reinforce; All there is chamfering each gusset plate and beam contact position, to increase contact area.By increasing weld flange plate on beam, the shear strain value with the steel frame of not contour girder steel is reduced, and twisting property improves greatly, is conducive to improving the anti-seismic performance with the steel frame of not contour girder steel.
Description
Technical field
The utility model relates to a kind of linkage of not contour girder steel, for reinforcing the Nodes of the steel frame with not contour girder steel, arranged by a series of plate and form, comprise frange plate, direct-connected fishplate bar, inclined connection plate and haunch connected system, shallow beam and deep beam are connected on pillar.Belong to design of building structures and the construction field of civil engineering.
Background technology
In recent years, with the steel frame of not contour girder steel due to its superior toughness and energy dissipation capability, steel work Lateral Resistant System has been widely used in.Being welded to connect of SMRFs all there occurs serious destruction in earthquake, causes the investigation of people to its fracture producing cause, and finds, be occur on the weld seam bottom beam and between post, and carried out various reinforcing.
But reinforcement measure common at present still also exists certain deficiency: be only confined to the effect strengthening welding, and improve the geometry and material properties that connect.
Therefore, the basis of existing reinforcement measure is improved, adopt a series of plate to arrange, comprise frange plate, direct-connected fishplate bar, inclined connection plate and haunch connected system, shallow beam and deep beam are connected on pillar.Can effectively reduce shear strain value, twisting property is improved greatly, this shockproof control for Practical Project is significant.
Utility model content
In order to solve for traditional reinforcement measure of the steel frame with not contour girder steel problem limited in one's ability, the purpose of this utility model is that proposing a kind of special bending resistance square for not contour girder steel place connects, this device is arranged by a series of plate and is formed, comprise frange plate, direct-connected fishplate bar, inclined connection plate and haunch connected system, shallow beam and deep beam are connected on pillar.Shear strain value with the steel frame of not contour girder steel is reduced, and twisting property improves greatly, is conducive to improving the anti-seismic performance with the steel frame of not contour girder steel.
To achieve these goals, the utility model takes following technical scheme.
The linkage of the not contour girder steel that the utility model proposes, comprises frange plate 1, direct-connected fishplate bar 2, inclined connection plate 3 and haunch connected system 4, wherein:
For the steel frame with not contour girder steel, the place contacted with mullion at deep beam or shallow beam side is all welded with frange plate 1; Described frange plate 1 is welded in outside the edge of a wing of deep beam or shallow beam side end, deep beam or or shallow beam on all need arrange, for reinforcing the attachment weld place of deep beam or shallow beam side and mullion; Described frange plate deep beam or or shallow beam on all need to arrange, the torsional property of Nodes can increased greatly, raising maximum shear strain value;
For the mullion between deep beam and shallow beam, between adjacent mullion, top adopts direct-connected fishplate bar 2 reinforcement of weld, and bottom adopts inclined connection plate 3 reinforcement of weld, or adopts direct-connected fishplate bar 2 and haunch connected system 4 jointly to reinforce.
In the utility model, described frange plate 1, direct-connected fishplate bar 2, inclined connection plate 3 and haunch connected system 4 all has the chamfering in outside with deep beam or shallow beam contacts side surfaces face place, to increase contact area, improves welding quality.
Compared with prior art, advantage of the present utility model is as follows:
1) experiment and analysis show, the consolidation effect of frange plate is very remarkable, and final the obtained ductility performance of this design, for after strength degradation 20%, total story drift is 0.06 radian, is much better than the reinforcement measure of tradition not with frange plate.
2) the utility model is arranged by adopting a succession of plate with frange plate, reinforces the connection on pillar, overcome the deficiency of traditional reinforcement measure by shallow beam and deep beam.Shear strain value with the steel frame of not contour girder steel is reduced, and twisting property improves greatly, is conducive to improving the anti-seismic performance with the steel frame of not contour girder steel.
3) the utility model reinforcing joint unit structural form is simple, can arrange different combinations, make the welding of junction plate more convenient, to reach good damping effect according to the feature of basic structure.
