Abstract
Provided is an anti-flexure support connecting beam, which is a novel shear wall connecting beam in a building structure. The utility model adopts a steel structure, and the rod member consisting of the connecting beam completely or partly adopts the anti-flexure support. The anti-flexure support mainly comprises an inner core energy consumption unit and a peripheral constraint unit. The anti-flexure support not only can be used a major axial bearing member, but also can be used as a major energy consumption damper in an earthquake. The quantity and the form of the anti-flexure support can be determined based on bearing capacity, rigidity and energy consumption requirement.
Description
Technical field
The utility model is a kind of novel shear wall coupling beam in the middle of the building structure.
Background technology
In shear wall structure system, the effect of the existing connection wall of coupling beam limb is also played certain effect of contraction to the wall limb that is connected.In seismic design, coupling beam still joins the first line of defence that the limb wall bends and destroys, and it can play the effect of dissipation horizontal earthquake load.
Existing coupling beam pattern mainly contains reinforced concrete coupling beams and steel work coupling beam.Reinforced concrete coupling beams can be divided into common arrangement of reinforcement reinforced concrete coupling beams, diagonally opposing corner intersection sleeper formula arrangement of reinforcement reinforced concrete coupling beams, rhombus arrangement of reinforcement reinforced concrete coupling beams again, establish the reinforced concrete coupling beams of straight joint reinforced concrete coupling beams, steel reinforced concrete coupling beam, band Frictional Slipping node.The steel work coupling beam has general steel work coupling beam and novel combination steel coupling beam
[1]
The reinforced concrete coupling beams ubiquity is from great, bearing capacity and energy dissipation capacity is limited, shortcomings such as difficulty are repaired in construction inconvenience and shake back.For overcoming the variety of issue of reinforced concrete coupling beams, from the nineties in last century, the steel work coupling beam has appearred.Test and elastic-plastic analysis result show, steel work coupling beam and reinforced concrete shear wall body of wall are formed mixes connection limb wall construction system and can guarantee enough rigidity, intensity and toughness, show good seismic resistance, be more suitable for the earthquake zone of setting up defences in strong degree.2003 have the people to propose a kind of novel composite coupling beams control structure system, and the truss that coupling beam is made up of hot-rolled steel section or welding shaped steel is formed, and on intermediate supports the friction energy-dissipating damping control apparatus can be set, and makes the steel work coupling beam more can realize energy-dissipating and shock-absorbing effectively
[1]
Continuous development along with highrise building, shear wall structure system is had higher requirement, the appearance of novel shear wall structural shapes such as Steel Reinforced Concrete Shear Walls, concrete filled steel tube shear wall is also had higher requirement to bearing capacity, rigidity, the power consumption of coupling beam.Aspects such as the rigidity of steel work coupling beam and energy dissipation capacity all remain further to be improved.
Summary of the invention
Be rigidity, the energy dissipation capacity that a step improves the steel work coupling beam, the steel work coupling beam is formed the anti-flexing supporting damping device of all or part of employing of rod member, form anti-flexing and support coupling beam.This pattern coupling beam remove have steel work coupling beam bearing capacity height, rigidity is big, be easy to shake the advantage that repair the back, its simple structure, easy construction, energy dissipation capacity are further strengthened.
The technical scheme that its technical problem that solves the utility model adopts is: anti-flexing is set in the shear wall coupling beam supports, form a kind of " anti-flexing supports coupling beam ".It is the cushioning members of developing in recent years that a kind of cost is low, power consumption is good that anti-flexing supports.Anti-flexing supports mainly to be made up of kernel power consumption unit, peripheral constraint element, and when being subjected to imposed load, because the effect of contraction of peripheral constraint element, kernel unit can reach the total cross-section surrender when pressurized, reaches the purpose of power consumption by the surrender hysteresis
[2]Anti-flexing is supported on the function identical with common support, and mainly as the axially loaded member, the axle power that only anti-flexing supports is born fully by kernel unit.The pressurized unstability that the peripheral constraint element that anti-flexing supports can effectively prevent to support, give full play to the superior elastoplasticity performance of steel.Anti-flexing supports and promptly can be used as the stressed member of coupling beam in normal operational phase, can bring into play good energy dissipation capacity and ductility again when earthquake, and has overcome the shortcoming that the steel work rod member is subject to the lateral deflection song.
The beneficial effects of the utility model are, anti-flexing supporting rod rigidity is big, and power consumption is strong, and other steel work coupling beam rod member quantity reduce relatively, construct simply relatively, and energy dissipation capacity also can be adjusted as required.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the anti-flexing of typical case supports front view.
Fig. 2 is that the anti-flexing of two kinds of typical cases supports sectional drawing.
Fig. 3 is several form exemplary plot that are provided with that anti-flexing supports.
The anti-flexing of Fig. 1 typical case supports in the front view: 1. be hoop; 2. be end plate.The anti-flexing of two kinds of typical cases of Fig. 2 supports in the sectional drawing: figure (a) is that the anti-flexing of cross inner core supports, and there is packing material inside, between cross steel and packing material non-cohesive material is arranged; Figure (b) is that the anti-flexing of in-line inner core supports inner no packing material
[3]Several setting in the form exemplary plot that the anti-flexing of Fig. 3 supports: figure (a) is the inverted V-shaped setting; Figure (b) is the V-arrangement setting; Figure (c) is the diagonal angle setting; Figure (d) is provided with for K shape; Figure (e) is the X-shaped setting; Figure (f) is provided with for z shape.Heavy line represents that anti-flexing supports among Fig. 3.
The specific embodiment
Fig. 1 is that the anti-flexing of typical case supports front view.Anti-flexing supporting form has multiple, but principle is similar substantially.The center of supporting is a core, is the main power consumption part that supports, and can adopt various types of steel work form of fractures, relatively is typically cross steel and in-line steel, as shown in Figure 2.Complete buckling when avoiding the core pressurized promptly can both reach surrender when tension and pressurized, core is placed in the steel sleeve, then perfusion coagulation or mortar in sleeve pipe.For reducing or eliminate and pass to mortar or concrete power when core is subjected to spool power, and because poisson effect, core can expand when pressurized, therefore is provided with one deck non-cohesive material or very narrow and small air layer between core and mortar.Inner core is that the anti-flexing supports outer of in-line steel is formed by the constraint of the clean steel member of side, because the frictional force between steel plate is quite little, so can not adopt no binding material also can reach good lateral restraint effect, this outside steel pipe damper is made simple than the concrete damper of outside steel pipe.
The shear wall coupling beam can adopt anti-flexing to support by all or part of rod member.The set-up mode that anti-flexing supports can be V-arrangement, diagonal angle setting, rhombus, X-shaped, Z-shaped and K shape.Fig. 3 is several form exemplary plot that are provided with that anti-flexing supports, and anti-flexing supporting type, quantity is set and form can be determined according to bearing capacity, rigidity and power consumption requirement.
