Description
Technical field
The utility model relates to building structure aseismatic prevention technique field, particularly a kind of buckling-restrainedSupport.
Background technology
Buckling restrained brace is a kind of important structure lateral resistant member and energy dissipation component, and it is by metalSurrender hysteresis consumes inputting seismic energy, thereby slows down the damage of agent structure, obtains in recent years in ChinaTo more application. Buckling restrained brace conventionally by supporting base end portion node, power consumption section (being core part),Tied mechanism (is confinement structure, has comprised concrete filled steel tube tied mechanism, clean steel tied mechanism, reinforcing barConcrete tied mechanism etc.) and tied mechanism in the composition such as non-cohesive material that arranges.
The mode that buckling restrained brace is connected with building structure comprised be welded to connect, bolt be connected andBearing pin connects. In the analytical calculation process of Architectural Structure Design, often supposition is supported with agent structure as cutting with scissorsConnect in succession (not power transmission moment), if but employing is welded to connect inevitable meeting in node junctionCarry-over moment, cause analytical calculation and the actual problem not exclusively conforming to, and bearing pin connection can be avoided thisOne problem, therefore, the other two kinds of connected modes of comparing, thus bearing pin connection has the end of release momentThe advantage such as more meet, attractive in appearance with calculation assumption.
Refer to Fig. 1 and Fig. 2, Fig. 1 shows the longitudinal section of a kind of buckling restrained brace of prior artStructural representation, Fig. 2 shows the cutaway view at A-A place in Fig. 1. Shown in Fig. 1 and Fig. 2Be the structural representation of the buckling restrained brace of bearing pin connection.

The 4th embodiment
Refer to Fig. 9 and Figure 10, the flexing that Fig. 9 shows the 4th embodiment of the present utility model approximatelyThe vertical section structure schematic diagram of bundle branch support, Figure 10 shows the cutaway view at the E-E place of Fig. 9. WithAbove-mentioned Fig. 3 is different with the first embodiment shown in Fig. 4, in this embodiment. Described bendingThe otic placode 2 that bent constraint is supported is not provided with recess 21, and one end of otic placode 2 directly and core part 1Splicing is connected. The end face of one end that as shown in Figure 9 and Figure 10, otic placode 2 is connected with core part 1The end face of size and core part 1 is roughly the same, is connected with core part 1 by the mode of butt weldingConnect. Specifically, otic placode 2 has inclined-plane with one end that core part 1 is connected, and otic placode 2 passes throughThis inclined-plane transits to the less end face chi consistent with core part 1 by larger cross sectional dimensionsVery little.
Further, in the embodiment shown in Fig. 9 and Figure 10, for to otic placode 2 and core portionReinforcement is carried out in point 1 stitching portion, and described buckling restrained brace also comprises pasting board 6. Pasting board 6 is arranged atCross section is the otic placode 2 of yi word pattern and the both sides of core part 1, is positioned at otic placode 2 and core part 1Junction. Wherein, pasting board 6 is smooth in the both sides of otic placode 2 and core part 1, is different fromState the floor 5 in the 3rd embodiment, it is due to larger with the contact-making surface of otic placode 2 and core part 1,And do not extend to outer sleeve 31, what therefore play is only the effect of reinforcement, and cannot realize anti-The only effect of the outer distortion of face.
Further, as shown in Figure 9 and Figure 10, in this embodiment, described buckling restrained braceAlso comprise reserved compression unit 7. Reserved compression unit 7 is positioned at the inside of outer sleeve 31, is arranged atBetween one end and packing material 32 that otic placode 2 is connected with core part 1, in described flexing approximatelyIn the situation of bundle supporting member bearing load, while giving described buckling-restrained bracing member pressurized, reserve oneThe space of section distortion. Reserved compression unit 7 preferably can fill the materials such as some plastic foams withIsolation otic placode 2 and packing material 32, play the effect of headspace. It should be noted that, reservedCompression unit 7 can be applied to the first above-mentioned embodiment, the second embodiment and the 3rd in fact equallyExecute in example, to play similar effect, it will not go into details herein.
In addition,, in the preferred embodiment shown in Fig. 9 and Figure 10, buckling restrained brace also comprises circleRing flat-plate 4. Circular Plate 4 is arranged at the both sides of otic placode 2, is positioned at the edge of pin shaft hole 22. These are realExecute example and can be achieved equally, do not repeat them here.
In sum, in conjunction with the embodiment shown in above-mentioned Fig. 3 to Figure 10, those skilled in the art's reasonSeparate, the supporting base end portion node of buckling restrained brace of the present utility model has omitted end plate and has been connected with elasticityThe structure of section and use monaural plate, compares with the buckling restrained brace that existing bearing pin is connected, at leastThere is supporting base end portion node and cancelled end plate conversion, avoid needing in order to use thicker end plate to meetThe problem that end plate requires along the stress performance of its thickness direction; Utilize cross section to be the core of yi word patternPart coordinates cross section to be the monaural plate of yi word pattern, can make buckling restrained brace meet everyUnder the prerequisite of support performance, make relatively more frivolous, saving cost of manufacture; Can adopt core part withThe connected modes such as the rear pasting board reinforcement of otic placode docking or flute profile connection, increase and play power consumption to the full extentThe length of core part of effect, is more conducive to the beneficial effect such as fatigue behaviour of buckling restrained brace.
