Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model technology is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit utility model.
nullAs illustrated in fig. 1 and 2，The not through concrete power consumption partition wall that cracks of the few arrangement of reinforcement local strengthening type of a kind of Disjunction type，Including concrete walls 1 and be arranged on the Vierendeel girder 2 around concrete walls 1 and frame column 3，Described concrete walls 1 can use low-grade concrete to be directly connected with Vierendeel girder 2 and frame column 3，Some perps 7 it are provided with in described concrete walls 1，Described concrete walls 1 are not provided with perps 7 with frame column 3 link position，The thickness of described concrete walls 1 less than frame column 3 in the 1/3 of corresponding wall thickness direction size，Described some perps 7 are along the arrangement of concrete walls 1 length direction and relative to the body of wall of the not through concrete walls 1 of concrete walls 1 short transverse，Wall stiffness can be reduced by the setting of not elongated perps and increase wall ductility and energy dissipation capacity，Described perps 7 is positioned at the centre position of concrete walls 1，The length of described perps 7 is not more than 1/2 that frame column 3 post of concrete walls 1 correspondence is high，On described perps 7、The spacing of lower end distance Vierendeel girder 2 is respectively greater than 1/4 that frame column 3 post of concrete walls 1 correspondence is high，The width of described perps 7 is 10～20mm，It is filled with flexible sealing material inside described perps 7，Vertical reinforcing bar 4 two ends arranged in described concrete walls 1 are anchored in Vierendeel girder 2，Connection horizontal reinforcement 5 two ends being not provided with described perps 7 location arrangements are anchored in frame column 3，Described vertical reinforcing bar 4 adopts distributed arrangement of reinforcement and concentration of local to strengthen the reinforcing plan that arrangement of reinforcement combines with connecting horizontal reinforcement 5，In described concrete walls 1、Perps 7 location arrangements is set and has Disjunction type horizontal reinforcement 6，Described Disjunction type horizontal reinforcement 6 disconnects at perps 7 place，It is arranged only in corresponding wall limb.Described partition wall functions only as the compartment under construction, provides proper stiffness and undertake the effect of certain level load, do not undertake vertical load, therefore textural Vierendeel girder, the frame column reserved joint bar of adopting, colligation Disjunction type horizontal reinforcement, the method finally watering wall member.In body of wall, reinforcing bar functions only as the effect preventing from dodging down outside wall plane, and C6 and C8 minor diameter reinforcing bar, Disjunction type horizontal reinforcement diameter can be used to be not more than the interior vertically bar diameter of same wall limb.Arranging perps region for inducing crack location in body of wall to be positioned in the middle part of body of wall further, around body of wall, stiffener diameter should be greater than distribution bar and stiffener in the middle part of body of wall.
For preventing crack in the body of wall relatively early destroyed from diffusing into Vierendeel girder and frame column, perps should elongated setting, existing result of study shows, when perps length high less than frame column post 1/2 time, the crack that wall damage produces will not expand among Vierendeel girder；When thickness of wall body less than frame column when the 1/3 of wall thickness direction size, wall damage produce crack will not expand in the middle of frame column.Therefore, the length of perps in body of wall must be limited within frame column is high 1/2, and be positioned at the medium height position of body of wall；Body of wall wall thickness must be limited in frame column within the 1/3 of wall thickness direction size.
Wherein, body of wall between adjacent two perps 7 forms wall limb, each section of wall limb depth-width ratio between described perps 7 is more than 2, namely the gap ratio between the length of perps 7 with adjacent perps 7 is more than 2, it is all wall limb bent horizontal rigidity sums that full wafer opens concrete walls 1 horizontal rigidity of perps 7, described in open concrete walls 1 horizontal rigidity horizontal rigidity less than masonry partition wall of perps 7；In described distributed arrangement of reinforcement, the arrangement of vertical reinforcing bar 4 is monolayer distribution formula arrangement of reinforcement in each section of wall limb, the arrangement of described connection horizontal reinforcement 5 is for be not provided with perps 7 region monolayer distribution formula arrangement of reinforcement at concrete walls 1, described Disjunction type horizontal reinforcement 6 monolayer in each section of wall limb is arranged and not through perps, described concentration of local strengthens in arrangement of reinforcement vertical reinforcing bar 4 multilayer distributed arrangement of reinforcement and concentrate on two ends and the middle part of concrete walls 1 in corresponding section wall limb, described connection horizontal reinforcement 5 is arranged in perps 7 two ends and multilayer distributed arrangement of reinforcement, all rebar ratio that described distributed arrangement of reinforcement and concentration of local are strengthened in arrangement of reinforcement are 0.10～0.25%.
The force-mechanism changing wall stiffness and ductility by arranging perps is in that, if the back wall of seam becomes a series of wall limb, each section of wall limb depth-width ratio does not relatively set seam body of wall and all dramatically increases, so that the failure mode of body of wall destroys from the shearing-type of full wafer wall, the flexure type becoming each section of wall limb destroys, and therefore wall ductility increases along with the increase of every section of wall limb depth-width ratio.Body of wall initial stiffness is changed to all wall limb bent horizontal rigidity sums by shearing rigidity, therefore, it can control the horizontal rigidity value of body of wall by changing the quantity arranging perps, and the rigidity of full wafer body of wall reduces along with the increase of perps quantity.In order to ensure that each section of wall limb is all that flexure type destroys when undertaking horizontal loading, it is desirable to either segment wall limb depth-width ratio is more than 2.Simultaneously in order to ensure that few muscle cracks wall in the structure as partition wall work, abundant perps need to be set and make few muscle crack wall horizontal rigidity less than corresponding tradition masonry partition wall, can also consider as partition wall in Structure Calculation.
A small amount of arrangement of reinforcement is arranged in body of wall, result of the test shows, arranging under the premise of perps and a small amount of arrangement of reinforcement at body of wall, under the different ratios of reinforcement, few muscle opens the rigidity of perps wall, bearing capacity, energy dissipation capacity all closely, and to open the rigidity of perps wall, bearing capacity, energy dissipation capacity close with identical plain concrete.Illustrate that few muscle cracks wall mainly through the friction after concrete pressurized and concrete destruction, occlusion undertakes horizontal loading, and the seismic energy of the input that dissipates, the load that reinforcing bar self surrender undertakes is all very little with the ratio shared by energy of dissipation, therefore, a small amount of reinforcing bar functions only as the effect preventing from dodging down outside wall plane, do not play stress effect, therefore the ratio of reinforcement relatively can have bigger reduction by shear wall minimum steel ratio, the scope of desirable 0.10%～0.25%, form of reinforcement can adopt disjunction local strengthening formula arrangement of reinforcement, local is carried out strengthening arrangement of reinforcement by the basis of normal distribution reinforcing bar.The strong position that adds of vertical reinforcing bar is arranged on body of wall two ends and frame column junction, also can strengthen by the some wall limbs in interval in body of wall centre position when body of wall length is longer, and horizontal reinforcement adds strong position and is arranged on Bu Shefeng region, body of wall perps two ends.The drawknot system arranging similar " ring beam and construction column " that stiffener makes reinforced region be formed on the one hand can better increase the globality of body of wall, prevent from dodging outside wall plane, body of wall zone line opposed peripheral regions is made to be more prone to crack on the other hand, zone line can be occurred in by induced fractures, crack is avoided to be diffused in Vierendeel girder frame column while dissipation energy, it is ensured that the performance of main structure body.
Connecting horizontal bar in normal distribution muscle and be anchored among frame column, vertical bar is anchored in the middle of Vierendeel girder, and disjunction horizontal bar is arranged in each section of wall limb.Horizontal reinforcement is discontinuous in perps position can greatly increase the convenience setting seam in construction, and meanwhile, each wall limb of body of wall is more independent, and mechanical concept is definitely.Arrange in perps region at body of wall, Disjunction type horizontal reinforcement is not anchored in frame column, therefore, it is impossible in the horizontal direction body of wall is carried out operative constraint, but within the scope of wall limb, increase wall limb globality, induction wall limb bends destruction, relies primarily on the vertical reinforcing bar being anchored in Vierendeel girder with the drawknot of agent structure, therefore, need in each section of wall limb, all arrange vertical reinforcing bar, it is particularly well-suited to body of wall length big, perps negligible amounts, the situation of wall limb negligible amounts.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
