Description
Technical field
The utility model relates to a kind of steel coupling beam, particularly has the replaceable steel coupling beam of span centre clean cut system of flexible replaceability after a kind of shake, belongs to building energy-dissipating and shock-absorbing technical field.
Background technology
As everyone knows; the energy-dissipating and shock-absorbing technology of coupling beam is mainly through setting up energy consumer or energy-consuming parts in coupling beam end or span centre; for total provides certain additional stiffness or additional damping; dissipate mainly through energy-consuming parts under external force, geological process or wind action and input the energy of building structure; to alleviate the dynamic response of building structure; thus protect the safety of agent structure better, be a kind of effectively, safety, economy and the engineering cushion technique of day by day maturation.Energy-consumption shock-absorption device mainly contains Metallic damper, friction energy dissipation device, viscoelastic damper, viscous damper, the energy dissipation behavior of first two energy consumer is main relevant with the relative displacement at energy consumer two ends, be called displacement relationship type energy consumer (or hysteresis type energy consumer), the energy dissipation behavior of latter two energy consumer is main relevant with the relative velocity at energy consumer two ends, is called velocity correlation type energy consumer.
Coupling beam is in Coupled Shear Wall except needing enough strength and stiffness and providing enough constraints to wall limb, and its another major function is exactly that the seismic energy protection wall limb dissipating a large amount of exempts from heavy damage.And existing coupling beam probably has following two kinds: the first adopts different reinforcement manner or construction measure to strengthen the energy dissipation capacity of coupling beam for traditional reinforced concrete coupling beams, such as configuration intersects secretly supports, rhombus arrangement of reinforcement, in coupling beam, establish the multiple methods such as seam, but the construction of the dark support of intersection acquires a certain degree of difficulty; The second replaces reinforced concrete coupling beams by steel coupling beam or composite coupling beams, composition mixing Coupled Shear Wall structure, namely body of wall remains traditional reinforced concrete wall, coupling beam adopts steel coupling beam or composite coupling beams, its objective is and carry out dissipation energy by the ductile deformation of steel coupling beam or composite coupling beams, but its shortcoming to be repaired after shake or more cost is higher.Above two kinds of deficiencies make this type of coupling beam receive different restrictions in actual applications.
Utility model content
Based on above-mentioned defect, the utility model proposes the replaceable steel coupling beam of a kind of span centre clean cut system, for solve seismic energy dissipate and energy-dissipating device to cause there is larger plastic displacement destroying after the technical problem that can not change rapidly.
The technical solution of the utility model is as follows:

Further, what described edge of a wing force transmitting board also comprised span centre position and two ends does not weaken position, and not weakening between position with the upper and lower edge of a wing of steel I-beam of described power consumption plate is all fixedly connected with by high strength bolt.
Further, the position that do not weaken of the every one end of described edge of a wing force transmitting board has all been arranged symmetrically with 4 high strength bolts; The position that do not weaken of described every one end of power consumption plate has all been arranged symmetrically with 4 frictional high-strength bolts.
The operating principle of span centre clean cut system steel coupling beam of the present utility model is: Shear Walls limb produces horizontal movement or corner under external force, geological process or wind action, the steel I-beam of adjacent both walls limb is driven to move, the movement of steel I-beam makes web power consumption plate and edge of a wing force transmitting board produce displacement or corner, power consumption plate surrender before, by produce between two block plates by high-strength friction bolt connection frictional force consume portion of energy; Along with the continuation of structure relative displacement or corner increases, power consumption plate enters the plastic stage gradually by elastic stage, when it is about to reach yield strength, by choosing the force transmitting board of appropriate size and power consumption plate, it is made to have precedence over steel I-beam surrender, enter plastic state in advance and produce plastic displacement, external force is done work in this displacement, thus dissipation energy.When power consumption plate larger plastic strain occurs so that impact normally uses after shake, can be dismantled rapidly and be changed the sheet material that completely newly consumes energy, be reached the effect changed flexibly.
Beneficial effect:
Adopt steel coupling beam of the present utility model, under external force by the force transmitting board of choosing appropriate size and power consumption plate, can make its comparatively overall structure enter plastic state in advance, and then dissipation energy, change flexibly after there is shake, convenient the effect with construction be installed.Which solve the deficiency of existing power consumption coupling beam, energy is transmitted to span centre power consumption plate by steel I-beam, and span centre power consumption plate can provide dual defence line, and there is the advantage changed flexibly, thus improve energy-dissipating and shock-absorbing effect and rehabilitation expense after reducing shake.
