By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this manual below.
Refer to Fig. 1 to Fig. 4.Notice, appended graphic the illustrated structure of this manual, ratio, size etc., equal contents in order to coordinate manual to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the present invention can produce and the object that can reach, all should still drop in the scope that disclosed technology contents can contain.Simultaneously, in this manual, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of narrating clearly, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the present invention.
As shown in Figures 1 to 4, what the invention provides that a kind of buckling-restrained steel plate wall is connected with concrete frame wears muscle connected node, it comprises the splice bar 1 for being connected with buckling-restrained steel plate wall, and be used for the connector that is connected with concrete frame, connector comprises that two junction plates that be arranged in parallel 2 and two ends are vertically connected on respectively two indented barss 3 on junction plate 2, junction plate 2 is parallel with the beam of concrete frame or the surface of post, splice bar 1 setting vertical with junction plate 2.The present invention adopts indented bars 3 to be embedded in beam or post inside is used for being connected with concrete frame, adopt splice bar 1 to be connected with buckling-restrained steel plate wall, two junction plates 2 form the middle bridge of total, this muscle connected node of wearing can be made in advance in factory, field fabrication during without construction, and because indented bars is embedded in the inside of beam or post, so it is convenient to the vertical muscle 7 of post on beam vertical muscle 5, beam stirrup 4 or the post on beam, arrangement and the colligation of column tie-bar 6.
Be illustrated in figure 1 the concrete distribution map that Liang Zhongben wears muscle connected node, above-mentioned splice bar 1 is two, be connected with two junction plates 2 on above-mentioned connector respectively, be used for being connected with the buckling-restrained steel plate wall of beam both sides, two junction plates 2 are placed in beam stirrup 4 outsides of beam.As shown in Figure 4, what be connected with post wears in muscle connected node, and above-mentioned splice bar 1 is one, is connected with one of them junction plate 2, is used for being connected with the buckling-restrained steel plate wall of post one side, and wherein junction plate 2 does not stretch in the connected node of beam and column.
The eccentric throw of above-mentioned splice bar center line and junction plate center line is half of splice bar thickness and buckling-restrained steel plate wall thickness sum.Above-mentioned splice bar 1 is all connected by the butt weld of full penetration groove with two junction plates 2, and this weld seam Ying factory has welded.The object that splice bar 1 is set is not only to facilitate the joint connection in site of buckling-restrained steel plate wall and connector, can increase the out of plane stiffness of junction plate simultaneously, reduces whole distortion of wearing muscle connected node.
Embedded steel plate wall in the present invention (referring to buckling-restrained steel plate wall for ease of describing " steel plate wall " in the present embodiment) can be connected by being positioned at two fillet welds of splice bar end and buckling-restrained steel plate wall end with splice bar 1, or connect by the butt weld of full penetration groove, also can adopt high-strength friction bolt connection.When adopting fillet weld, the fillet weld of splice bar end should adopt unequal-leg fillet welds to realize the transition of different-thickness steel plate.When adopting butt weld, should guarantee the machining accuracy of steel plate wall, and all butt weld should reach first quality requirement.
In the present invention, the quantity of indented bars 3 can be determined according to the dowel total cross-sectional area that meets requirement for bearing capacity, and the external load within the scope of above-mentioned connector unit length is calculated by the definite shearing of buckling-restrained steel plate wall ultimate shearing strength or the pulling force of being determined by ultimate tensile strength.The arrangement of indented bars 3 should meet the requirement that code for structural design is arranged dowel.
The width of above-mentioned junction plate 2 requires to determine by meeting the arrangement of above-mentioned indented bars 3, and thickness should be according to stressing conditions calculative determination, and should not be less than indented bars diameter 60% and indented bars spacing 1/8.
Take concrete frame-tetra-limit below connects buckling-restrained steel plate wall as example, and the Specific construction process of wearing muscle connected node of the present invention that adopts is described.If will arrange buckling-restrained steel plate wall in a certain reinforced concrete frame, first the beam of the direct power transmission of buckling-restrained steel plate wall, post are designed, make its requirement that meets bearing capacity and stiffness, can connect as four limits the operative constraint member of buckling-restrained steel plate wall.The horizontal loading of sharing according to buckling-restrained steel plate wall is determined steel plate wall thickness simultaneously.
Before concrete frame structure construction, by splice bar 1, two junction plates 2 and indented bars 3, in advance in factory process and connect into integral body, above-mentioned indented bars 3 is connected with junction plate 2 employing plug weldings.Wherein the external surface of two junction plates 2 is concordant with the upper and lower surface of beam or the inside and outside surface of post respectively, and splice bar center line and junction plate center line eccentric throw are half of splice bar thickness and embedded steel plate wall thickness sum.Splice bar 1 is connected by the butt weld of full penetration groove with junction plate 2, and the quantity of indented bars 3 is determined according to the dowel total cross-sectional area that meets requirement for bearing capacity.
During construction, by originally wearing muscle connected node, be embedded in advance concrete component inside with beam, post steel bar overall binding that buckling-restrained steel plate wall position need to be set.After concreting completes, concrete with originally wear being connected of muscle connected node and constructed.After the construction of main body concrete frame structure is complete, embedded steel plate wall is connected with splice bar 1, connected mode can adopt fillet weld, butt weld or frictional high-strength bolts.
In sum, the buckling-restrained steel plate wall of the present invention is connected with concrete frame wears muscle connected node, employing indented bars is arranged on beam or post inside is used for being connected with concrete frame, adopt splice bar to be connected with buckling-restrained steel plate wall, two junction plates form the middle bridge of total, this muscle connected node of wearing can be made in advance in factory, field fabrication during without construction, and be convenient to the vertical muscle of post on beam vertical muscle, beam stirrup or the post on beam, arrangement and the colligation of column tie-bar.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
