Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, the Self-resetting energy dissipation node of gas concrete out-hung panel provided by the invention, comprises stirrup circle 10, upper and lower connector 20,30 and two connecting bolts 40.
The inside and outside surface of stirrup circle 10 ring set gas concrete out-hung panel 50 is arranged, and lock ring gas concrete out-hung panel 50 forms an entirety;
Upper and lower connector 20,30 is separately fixed at stirrup circle 10 towards on the surface of indoor, and upper and lower connector 20,30 lays respectively at the upper and lower of stirrup circle 10.
As shown in Figure 2, upper and lower connector 20,30 structure is identical, and for upper connector 20, upper connector 20 has orthogonal horizontal part 21 and vertical portion 22, and vertical portion 22 is fixed with stirrup circle 10, and horizontal part 21 is provided with an elongated hole 23 parallel with vertical portion.
The position of upper connector 20 is corresponding with the upper strata Vierendeel girder 51 of building, the position of lower connector 30 is corresponding with lower floor's Vierendeel girder 52 of building, on the bottom surface that upper and lower connector 20,30 is separately fixed at the upper and lower layer Vierendeel girder 51,52 of building through corresponding elongated hole by connecting bolt 40 and end face.Specifically, be fixed on the bottom surface of upper strata Vierendeel girder 51 by connecting bolt 40 through the elongated hole on upper connector 20, be fixed on the end face of lower floor's Vierendeel girder 52 through the elongated hole on lower connector 30 by connecting bolt 40.The upper and lower edge of upper and lower connector 20,30 distance gas concrete out-hung panel 50 is provided with certain distance (half of Vierendeel girder height), to ensure the perfection docking of upper and lower layer gas concrete out-hung panel, after docking, between upper and lower layer gas concrete out-hung panel, gap is very little.
As shown in Figure 3, in order to realize the auto-reset function of Self-resetting energy dissipation node, being provided with two flexible members 41 and forming Self-resetting energy-dissipating device in elongated hole, two flexible members 41 are fixed with the inwall at connecting bolt 40 and elongated hole two ends respectively.
In the present embodiment, what upper and lower connector 20,30 all adopted is angle steel, and what flexible member 41 adopted is spring, and gas concrete out-hung panel 50 is longitudinally installed.
As shown in Figure 4, stirrup circle 10 is the circulus 11 that a batten is bent to form, two free end joint respectively to be bent to form outward two be oppositely arranged first, second mounting plate 12, 13, first, second mounting plate 12, 13 are provided with and relative run through through hole 14, circulus 11 ring set is in gas concrete out-hung panel 40, on external surface, by fastening bolton first, second mounting plate 12, 13, make stirrup circle 10 clamp gas concrete out-hung panel 40 and form an entirety, guarantee that stirrup circle 10 can not come off, add the overall performance of gas concrete out-hung panel.
Wherein, first mounting plate 12 is provided with many rows and runs through through hole 14, second mounting plate 13 is provided with a row and runs through through hole 14, by selecting the through hole that runs through of different row on first, second mounting plate 12,13 to be fixed, grade adjustable ground that has realizing stirrup circle 10 pairs of gas concrete out-hung panels applies fastening force.
In the present invention, stirrup circle 10 is utilized to clamp gas concrete out-hung panel 40, the destruction that pre-buried iso-stress of can effectively avoiding punching is concentrated and produced, and can be lifted gas concrete out-hung panel by stirrup circle or mobile, greatly facilitate construction.
Upper and lower connector 20,30 is fixed on (relevant position on constructure body structure arranges built-in fitting) in the agent structure of building by connecting bolt 40, because connecting bolt 40 can slide along elongated hole 23 under the effect of certain external force, therefore, can be considered " flexibly connecting " and have fraction power consumption function, upper and lower connector 20,30 is born horizontal direction load and does not bear vertical load.While the load of gas concrete out-hung panel 50 is effectively delivered to agent structure carrying by upper and lower connector 20,30, agent structure relative storey displacement can also be coordinated and become.Vertical component effect and the gas concrete out-hung panel 50 of upper and lower connector 20,30 are fixed together, and when coming earthquake, gas concrete out-hung panel 50 can be free to slide, and produce friction while slip, consume part seismic energy.
Utilize the method for above-mentioned Self-resetting energy dissipation node construction gas concrete out-hung panel as follows:
First the inside and outside surface of stirrup circle 10 ring set gas concrete out-hung panel 50 is arranged, and lock ring gas concrete out-hung panel 50 forms an entirety;
Stirrup circle 10 is welded and fixed a connector (hot rolling equal angle steel of ∠ 100mm × 100mm × 10mm) respectively towards the upper and lower on the surface of indoor, wherein, angle steel gets out the elongated hole of 60mm × 14mm in advance on a side, then another side of angle steel and stirrup lap welding is connected together;
Stirrup circle 10 internal orifice long for 600mm, wide be 120mm, high be 300mm, stirrup circle 10 thickness is 10mm, the welding procedure adopted is melting welding, in welding process, angle steel interface is heated to molten state, form continuous weld after cooling and two workpiece are connected in one, guarantee the bulk strength of angle steel and stirrup circle 10 and stablize.
What gas concrete out-hung panel 50 adopted is the gas concrete out-hung panel of the A2.5 intensity being of a size of 600mm × 300mm × 1500mm; connecting bolt 40 is M15mm × 30mm; this node planar can produce slippage; when load is excessive, connector can produce slippage protection gas concrete out-hung panel.
The Self-resetting energy-dissipating device that two spring assemblies are formed is provided with in elongated hole 20, one end and the connecting bolt of spring assembly are fixed, the sidewall at the other end and elongated hole two ends is fixed, like this when earthquake due to the power consumption of spring assembly, the seismic energy that is delivered to gas concrete out-hung panel can be reduced thus avoid the destruction of gas concrete out-hung panel.After shake, due to the return action of spring assembly, the gas concrete out-hung panel " waved " in earthquake is forced to automatically reset.
Stirrup circle should spray fire resisting paint and carry out conservation treatment.
Scheme provided by the invention, has following significant advantage:
(1) connection of gas concrete out-hung panel can be realized easily, and there is when earthquake larger relative storey displacement value, protect plug-in aerated concrete wall not destroyed when earthquake.
(2) stirrup circle can retrain aerated concrete wall, increases the overall performance of body of wall, makes aerated concrete wall stress performance more reasonable; Can be carried out lifting or the movement of body of wall by stirrup circle, constructability lifts, and the reduction of erection time, is applicable to the popularization of industrialized house.
(3) during earthquake, due to the distortion of Self-resetting energy-dissipating device, the energy thus the damage avoiding body of wall that are delivered to body of wall can be reduced.After shake, due to the return action of spring assembly, the gas concrete out-hung panel " waved " in earthquake is forced to automatically reset.
(4) do not need renewal part, the use of next time can be met, save cost.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
