The rigid nodes are characterized in that the cantilever beams are fixed with the columns; cover plates which are simultaneously fixed with the columns and the cantilever beams are respectively arranged on upper flange and lower flange of the combined end of the cantilever beams and the columns; the cantilever beams are connected with beam web plates through web plate and splice plate bolts and are respectively connected with the upper flanges and the lower flanges of the beams through dual-layer splice plate bolts; and weakening parts are arranged in the middle of an flange outer layer splice plates. Therefore, the utility model ensures the outer movement of plastic hinges at the beam end, increases the plastic corners at the beam end, improves the earthquake-resistant performance of the nodes, is convenient for maintenance and reinforcement after the earthquake and simultaneously achieves the optimal economic effect.
Description
Technical field
The utility model relates to the building steel framed structure, the modified steel frame beam column rigid joint that especially a kind of beam-ends reinforcement-edge of a wing scab weakens.
Background technology
Traditional steel frame beam column rigid joint is the edge of a wing of beam 3 and post 1 ' welding, and web directly passes through bolt 7 bolts with post scab 8 ', as Fig. 1 (a) with (b); Or for being with the beam-column connection of semi girder 2, the beam column junction of this node is that the edge of a wing of semi girder 2 and web and post 1 ' weld by factory, the other end of semi girder 2 and beam 3 are by web scab 8 " carry out the bolt weldering and mix and is connected; as Fig. 2 (a); or splice by bolt 7 full bolts fully, shown in Fig. 2 (b).
Though above-mentioned node has been widely used in the steel framed structure, node is the weak link of whole frame construction, in the destructive insident such as bursts such as earthquake disasters, has fatal defective.For example, California, USA earthquake in 1994 and nineteen ninety-five Japan's slope earthquake centre celestially, rupture failure has all taken place in many traditional beam-column connections, and wherein most fracture starts from the bottom flange weld seam of node beam-ends, the surrender and the flexing of the steel member of expection do not occur.Therefore, how improving the anti-seismic performance of node, is the crucial part that improves whole frame construction anti-seismic performance.But, adopt reinforced node can increase column cross-section size merely, beam section utilizes insufficient, and is less economical, and can influence the lateral rigidity of beam.Therefore, the design people proposes improved technical scheme at above-mentioned situation.
The utility model content
The utility model purpose is, the modified steel frame beam column rigid joint that provides a kind of beam-ends reinforcement-edge of a wing scab to weaken, to improve the mechanical property of traditional bean column node, anti-seismic performance particularly, design principles according to " strong column and weak beam, the weak rod member of strong node " in the seismic design, the node beam-ends is adopted rational reinforcement, improve the anti-seismic performance of node, and reach preferable economic effect simultaneously.
According to above-mentioned purpose, the modified steel frame beam column rigid joint that a kind of beam-ends reinforcement-edge of a wing scab weakens, it is characterized in that semi girder and post weld in factory, the bottom flange respectively is provided with a cover plate that is connected simultaneously with post and semi girder in the binding end place of semi girder and post; Semi girder is connected by web scab bolt with web, and semi girder then respectively is connected by double-deck edge of a wing scab bolt with the last bottom flange of beam, and outer scab middle part, the edge of a wing is provided with weakening portion.
Wherein, described weakening portion is the arc notch of symmetry, and is separately positioned on the both sides in the middle part of the outer scab in bottom flange.
Wherein, semi girder and post are that full welding is fixing.
Wherein, described post is box column or the I shape post with rectangle or square-section.
Wherein, be equipped with diaphragm in described box column or the I shape post.
Wherein, connect that each double-deck scab of bottom flange is connected and fixed with bolt on described semi girder and the described beam.
Wherein, the cover plate that is positioned at the semi girder top flange is a trapezium structure, is trapezoidal base one side it combines with post; The cover plate that is positioned at the semi girder bottom flange then is rectangular configuration.
Pass through said structure, the utility model adds cover plate to the semi girder end and strengthens, and last bottom flange scab carried out suitable reasonable weakening, by strengthening and weaken the corrective measure of combination, guarantee that plastic hinge moves outward, increase the plasticity corner of beam-ends, improved the anti-seismic performance of node, reach preferable economic effect simultaneously.
Secondly, the bottom flange respectively adds double-deck scab on splicing place beam, help the even transmission of power, the outer scab of wherein going up the bottom flange carries out circular arc type and weakens, thereby destruction is at first appeared on the scab of the edge of a wing, rather than appear on the web and the edge of a wing of beam, so both improved the node anti-seismic performance, the maintenance and reinforcement after being convenient to again shake.Should connect adopt factory's welding simultaneously, the building site weld seam has been avoided in high-strength bolt splicing in building site, has advantages such as the good and speed of application of weldquality is fast.
Below in conjunction with accompanying drawing a kind of specific embodiment of the present utility model is described, to disclose spiritual essence of the present utility model in more detail.Wherein, identical part is represented with identical Reference numeral.For the details of each several part in the exploded view clearly, the same structure in the different map sheets is not in strict accordance with the scale of reality.
