Specific implementation mode
Shown in Fig. 1-Fig. 5, present embodiment the technical solution adopted is that：It includes upper coupling beam 1, lower coupling beam 2,
Upper coupling beam 1 and lower coupling beam 2 are arranged between shear wall A together side by side；The upper coupling beam 1 includes coupling beam longitudinal reinforcement 11, connects
Beam transverse steel 12, coupling beam longitudinal reinforcement 11 and coupling beam transverse steel 12 are staggeredly formed bar-mat reinforcement and are arranged in the inside of shear wall A.
The coupling beam longitudinal reinforcement 11 and the same span centre of 12 diameter of coupling beam transverse steel, spacing a are 150mm.On top, Di Xiayou
The line of turnover is coupling beam longitudinal reinforcement 11, and intermediate single line is the coupling beam transverse steel 12 of shear wall, and vertical is coupling beam longitudinal direction
Reinforcing bar 11 is abound with along coupling beam transverse steel 12, and whole spacing a are 150mm, and diameter is constant.
The upper coupling beam 1 is identical with the structure of lower coupling beam 2.
Doubly-linked beam is that single coupling beam is decomposed into two the upper and lower coupling beam centainly to act synergistically, is equipped between upper and lower coupling beam
Certain spacing need not be attached in order to construct between upper underbeam, and can be designed, construct respectively.According to stress
The identical or different normal concrete beams scheme of deck-molding can be respectively adopted in the upper and lower beam of the difference of size, doubly-linked beam, above and below
The measures such as Stiffness degradation can also be respectively adopted in beam.For the doubly-linked beam of span identical as single coupling beam, since doubly-linked beam is different from
The coupling beams of two autonomous workings, but cooperative coupling beam, it is always high that the span-depth radio of Gu Shuanlianliang is defined as span/upper underbeam
Degree.The key point of structural seismic performance is the hierarchy of energy consumption and structure.It is exactly plasticity for ordinary concrete Structural Energy Dissipation member
The setting of hinge, doubly-linked beam virtually increases the redundancy of structural system and at hinge quantity, so as to effectively improve structural system
Shock resistance important building can actively be gone to be arranged consciously so being advantageous antidetonation.
Coupling beam builds the important function that energy consumption seismic energy is played in earthquake as important energy dissipation, and doubly-linked
Beam is the specially treated means to over-reinforced coupling beam, and so-called doubly-linked beam is exactly that horizontal joint is arranged in the middle part of coupling beam in over-reinforced coupling beam,
It is divided into two depth of sections equal or similar small bore coupling beam the coupling beam of the coupling beam of whole cross section height, then will crack double
Coupling beam carry out it is simple equivalent, i.e., it is equivalent according to the equal principle of coupling beam anti-shearing section area, finally press it is equivalent after coupling beam cut
Face carries out Structure Calculation, and the coupling beam progress arrangement of reinforcement for setting seam to level further according to result of calculation is related to.
Compared with lintel beam, doubly-linked beam has lot of advantages：First, the internal force of coupling beam can be preferably reduced, thus energy
The arrangement of reinforcement of coupling beam is enough reduced, therefore doubly-linked beam scheme has good economic benefit, and has good application value；And it can lead to
It crosses and different coupling beam spacing is set, convenient for Architectural Equipment, the arrangement of pipeline, it is proposed that spacing is more than 200mm, in addition when between upper underbeam
When away from more than 200mm, the upper underbeam of doubly-linked beam can be easy to construct respectively, thus doubly-linked beam scheme does not increase construction hardly possible
Degree.
Overreinforced destroys：When component tensile region quantity of reinforcement is very high, then tension reinforcement will not be surrendered when destroying, and destruction is because mixed
Solidifying soil compression edge reaches capacity caused by compressive strain, concrete be crushed, and when this destruction occurs, concrete in tension zone is split
Unobvious are stitched, are a kind of brittle breaks, since the destruction of over-reinforced beam belongs to brittle break, before destruction without apparent omen before destroying
Without warning, and the intensity of tension reinforcement is not fully utilized and uneconomical, therefore should not use.
The operation principle of the utility model：When over-reinforced coupling beam, the method for setting horizontal joint in the middle part of coupling beam is taken, it will be entire
The coupling beam of depth of section is divided into two depth of sections equal or similar small bore coupling beam, due to being limited by the means of calculating,
It is elongated that the progress of doubly-linked beam is simple equivalent in structure design, i.e., it is equivalent by the equal principle of coupling beam anti-shearing section area, it is equivalent
The width of coupling beam is 2 times of small bore coupling beam width, highly equal with small bore coupling beam, by it is simple it is equivalent after cross-section of coupling beam into
Row structural analysis and computation carries out Reinforcement Design further according to result of calculation to the coupling beam that horizontal joint is arranged.
After adopting the above technical scheme, the utility model has the beneficial effect that：Its simple possible, constructing operation are convenient, solve
The shear wall structure coupling beam shearing resistance deficiency and the problem of overreinforced in structure design and Specific construction.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
