Between the plural number of the connecting object piece Structural Steel Plate 2, insert a kind of in following nonferrous metal plate 7 or the composite ceramic slab 7, aluminium sheet at least, copper coin, stereotype, brass sheet, the titanium plate, zine plate, nickel plate, the thallium plate, corrosion resistant plate, silver plate, the gold plate, platinum plate, indium plate, the barium plate, the perhaps alloy sheets of these metals, and be to add the iron plate that the plating material forms with these metals, perhaps alumina plate, zirconium oxide plate, titanium oxide plate, the oxidation zine plate, boron nitride plate, silicon nitride plate, the nitrogenize aluminium sheet, Carborundum plate, charing titanium plate, the boride plate, sulphide plate, and their composite ceramic slab.
In addition, be clipped in the surface of nonferrous metal plate 7 between two Structural Steel Plates 2 or composite ceramic slab 7 at least outer circumferential face with insulating material 8, for example, viscoelastic material, cohesive material, silica gel, grease, pitch, wood tar, plastic cement, rubber etc. be by bonding, and perhaps outer be coated with etc. carried out water-proofing treating.
Shown in Fig. 1-1 (C), can set space δ 1 arbitrarily in running through between the screw rod periphery with interior week in hole and bolt of high-strength bolt 5.
As shown in Figure 2, by 6 pairs of high-strength bolts of nut 5 import fixed pulling force, nonferrous metal plate 7 adopts the aluminium sheet of certain specifications, and (JIS-H4000-A1100P JIS-H4000-A1050P), then can obtain very high friction factor.Solid line a among the figure represents bolt connection structure of the present invention, the conventional at present bolt connection structure that uses of dotted line b representative.From figure as can be seen, the friction factor that adopts bolt connection structure of the present invention is 0.9, is 2 times of friction factor 0.45 of current practice approximately.Also have, slide after the beginning, the frictional force of current practice can descend, and adopts the present invention that frictional force then can not take place and descends.And,, insert different nonferrous metal plates 7 as Figure 1-3 simultaneously if adopt, also can produce composite effect.
If be application target with the big surface friction drag behind about 1mm that slides, adopt shown in Fig. 1-4, elasticity of demand material and pressing plate are just not enough.More can reduce cost in this case.
In addition, carry out water-proofing treating, can prevent the water intrusion rubbing surface, avoid intermetallic generation galvanic action not of the same race by using insulating material 8.Therefore, can stop the coefficientoffriction change between Structural Steel Plate 2 and the nonferrous metal plate 7, form the bolt connection structure of safety and stability.
In addition, aforementioned elastic 3 requires not produce for the energy certain pressure of long term maintenance and creeps and relax, and the rubber of the not generating material deterioration of wrapping with metal around adopting or synthetic leather etc. are made.In addition, as shown in Figure 3, also can adopt metallic disk spring washer 3d, spring washer is perhaps to elastic material 3 additional desired pressure.
In the additional embodiments shown in Figure 4, between Structural Steel Plate 2 and the nonferrous metal plate 7, for example the rubbing surface (also claiming slip surface) to nonferrous metal plate 7 one sides carries out following bristle processing 9, sprays sand to rubbing surface, and the molecule of glass etc. makes generation concavo-convex.In addition, between the nonferrous metal plate 7 and Structural Steel Plate 2 of the non-slip surface of an opposite side of above-mentioned rubbing surface, joint compound layer 10 (resin series glue such as epoxy resin) is set, and to carry out brute force bonding.In addition can also be by welding, molten metals etc. make them integrated.
Therefore, the setting of nonferrous metal plate 7 just is easy to.Since to slip surface just rubbing surface carry out bristle and handle, friction factor (coefficient of friction of rest) μ is increased, under the effect of high-strength bolt 5, make between two Structural Steel Plates 2 reliably to be connected.
In addition, as shown in Figure 5, handle 9 method, also can select the non-slip surface of Structural Steel Plate 2 and the two sides of nonferrous metal plate 7 are all handled as rubbing surface being carried out bristle.
Fig. 1, Fig. 3, Fig. 4, Fig. 5 is the example that the periphery of the contact segment of nonferrous metal plate 7 is carried out water-proofing treating, in addition, and as the example among Fig. 6, when aforementioned nonferrous metal plate 7 is carried out water-proofing treating, be not only outer circumferential face, nonferrous metal plate 7 be immersed in the hutch of non-conductive material 8, water-proofing treating is carried out on its full surface also can.Like this, non-conductive material 8 is easy to attached on the nonferrous metal plate 7, can be easily between Structural Steel Plate 2 and the nonferrous metal plate 7 and carry out antirust processing definitely.When bolt was tightened, non-conductive material 8 was outwards extruded naturally, and the interface of Structural Steel Plate 2 and nonferrous metal plate 7 touches together.
Fig. 7 (A), (B) in represented embodiment, be the bolt hole that on Structural Steel Plate 11, forms bar hole (perhaps macropore) 11a, and the length direction in the hole can slide and becomes the legend of the bolt connection structure 12 of damper.Length direction (glide direction) between high-strength bolt 5 and the bar hole 11a has the gap of δ 2, as shown in Figure 8, (〉=P (setting bolt tension force) * μ) does the time spent as load Q, rubbing surface begins to slide, and it can absorb the vibrational energy that is equivalent to resume area that curve surrounds in the scope of ± δ 2.The value of gap delta 2 is about 50mm during the damping energy-dissipation structure, need 600mm during isolation structure approximately.
At the rubbing surface of damper, as friction plate, and make it keep certain pressure with nonferrous metal plate 7 by elastic material 3, can obtain stable coefficientoffriction.Be connected with nut 6a with high-strength bolt 5a, in the attachment portion of not using elastic material 3, because of total pressure is bigger, above-mentioned load Q does the time spent, can not produce slip.
The application examples of the bolt connection structure body 12 when use as the oscillation damping and energy dissipating damper at the post 20 among Fig. 9 and the joining portion of beam 21.In the application examples of the bolt connection structure body 12 shown in Fig. 9,,, occur in the bar hole 11a place in left side so slide because of 3 pressure spots are arranged though the right side part of figure also imports pressure by elastic material 3.In addition, be that bolt connection structure body 12 when using as the oscillation damping and energy dissipating damper is applied in the application examples on the bearing diagonal 22 between the beam 21 among Figure 10.
Bolt connection structure body 13 during using shown in Figure 11 as the oscillation damping and energy dissipating damper, be will have a differentiated friction resistivity good employ be earthquake with and small vibration with being that the part that wind resistance is used is connected in series the structure that forms along glide direction.Figure 11 (A), (B) in, the diameter of the high-strength bolt 5b on right side is thicker than the diameter of the high-strength bolt 5 in left side, is because when being subjected to certain oscillating action more than the degree, bolt 5b begins to be subjected to shear action.Therefore the area design of nonferrous metal plate 7a gets smaller.In addition, also more weak by elastic material 3 by the pulling force that nut 6b imports.The joint construction on right side part has just become the wind resistance damper like this.
Among Figure 11, δ's 1 is poor because the radial direction of the diameter of high-strength bolt 5b and bolt hole exists, as shown in figure 12, under effect by wind-induced load Q1, microvibration in the scope of ± δ 1, when load surpassed Q1, high-strength bolt 5b ran into the bolt hole wall, can not continue to move and was subjected to shear action.The left side of bolt connection structure body 13 is earthquake dampers, as shown in figure 12, under the effect of load Q2, slides in the scope of ± δ 2.This bolt connection structure body 13 has constituted damper simple for structure and the corresponding earthquake of energy and two kinds of effects of high wind.
The embodiment of the moving limiting device 26 that to be the Structural Steel Plate 11 of bolt connection structure body portion that the microvibration in the described bolt connection structure body 13 of Figure 11 is used and the slide relative amount between the nonferrous metal plate 7 limit in glide direction of the bolt connection structure body 14 during using among Figure 13 as the oscillation damping and energy dissipating damper.
