Abstract
The utility model discloses a combined-type buckling restrained brace which is used in the field of buildings, bridges and the like. A buckling restrained member is formed by welding upper channel steel and lower channel steel, wherein filling layers are poured in the upper channel steel and the lower channel steel. An axial force member is located at the position of junction of the upper channel steel and the lower channel steel in the buckling restrained member. A connecting piece is arranged at each of two end heads of the axial force member, wherein the connecting pieces and the two end heads are connected into a whole. The combined-type buckling restrained brace has the advantages that manufacturing technique is simple, performance parameters can be effectively ensured, seismic resistance and energy dissipation effects are good, volume production can be achieved, and the range of application is wide.
Description
Technical field:
The utility model and the shock-resistant and energy-dissipating device-dependent that is used for the fields such as building, bridge, ocean platform, communications tower, power transmission tower, large lifting equipment, special relevant with the combined type buckling restrained brace.
Background technology:
Buckling restrained brace generally partly is comprised of core stressed member, buckling-restrained parts, nothing bonding isolation and compressible stratum and end link etc., basic Force principle is: under the restriction of buckling-restrained parts, the core stressed member is in the cripling that integral body or low order can not occur near the axially loaded state all the time in whole loading process, thereby produces under external force the energy that the tension and compression plastic strain consumes the earthquake input structure.
Do the time spent in normal use or structure experience than small earthquake; the buckling restrained brace that arranges in the structure can provide effective support for structure; and under middle shake or rarely occurred earthquake effect; it will utilize surrender, the Hysteresis Behavior dissipation seismic energy of metal; the protection agent structure can be changed after the earthquake easily.Buckling-restrained parts are as the important component part of buckling restrained brace, enough bending rigidities need to be arranged, can guarantee that just the core stressed member is in comparatively desirable axially drawing, press stress and produce the tension and compression plastic strain, thus so that the superior energy-dissipating property of buckling restrained brace performance.In the existing buckling restrained brace, buckling-restrained parts generally adopt the mode of concrete placing, mortar in the whole steel pipe to come to provide constraint for the core stressed member.Complete buckling constraint component and the support inner core of putting in the inner need to support inner core coating or bonding anticreep agent before the concrete perfusion.Its processing technology is complicated, and core stressed member centering is poor, reserves extendable room and is difficult for guaranteeing, compressible section such as very easily destroys at the defective when concreting, mortar, cause the buckling restrained brace overall performance to can not get effective control, and performance parameter is unstable.
The utility model content:
The purpose of this utility model is in order to provide a kind of manufacturing process simple, and performance parameter can effectively be guaranteed, shock-resistant and energy-dissipating is effective, can be mass-produced, combined type buckling restrained brace applied widely.
The purpose of this utility model is achieved like this:
In the utility model combined type buckling restrained brace buckling-restrained member by inside build respectively the upper channel-section steel of packed layer, lower channel-section steel is welded, axle power member is positioned at the upper and lower channel-section steel of buckling-restrained member junction, be attached thereto respectively the all-in-one-piece connector on axle power member two ends, packed layer can adopt mortar or pea gravel concreten material to pour and form.
The two ends opposite position of packed layer has respectively draw-in groove in the above-mentioned upper and lower channel-section steel, respectively with two connectors that axle power member two ends links into an integrated entity on have respectively with corresponding upper and lower channel-section steel in packed layer on the card that is slidingly matched of draw-in groove.
Above-mentioned axle power member shape of cross section is " ten " font or " H " shape, and the through slot that cooperates with axle power member is arranged respectively on the packed layer of upper and lower channel-section steel.
Above-mentioned axle power member shape of cross section is rectangle.
Above-mentioned buckling-restrained member two ends has respectively cover plate.
Buckling-restrained member in the utility model is made of upper and lower channel-section steel and pours into packed layer (mortar or concrete) between the two, avoid in the traditional form supporting inner core and the integrated of concrete filled steel tube built, therefore supporting core surface need not to carry out without binder-treatment again, also need not to paste soft material at the support inner core and reserve the axial compression space, can solve well the problem of traditional form non-cohesive material local damage and soft material displacement when concreting, reduce the difficulty of production and construction, also guaranteed the quality of finished product simultaneously.
The utility model can according to flexural property carry out flexibly physical dimension design, manufacturing process succinctly clear, performance parameter can effectively be guaranteed, be particularly suitable for factory normalization production in enormous quantities and scene and match as required installation, shock-resistant and energy-dissipating is effective, applicable to the shock-resistant and energy-dissipating demand in the fields such as building, bridge, ocean platform, communications tower, power transmission tower, industrial equipment and support of pipelines, large lifting equipment.
