Description
Technical field
The present invention relates to bridge, building vibration damping antidetonation field, especially relate to a kind of variable method of the horizontal frictional force of bearing that makes.
Background technology
Subtracted in recent years seismic isolation technology at home bridge, building trade use widely, the performance of bearing also is suggested higher requirement because of the needs of structure.
Shown in Figure 1 is the essential structure of traditional bearing, and bearing top board 1 links to each other with works 6 respectively with base-plate 5 during installation.When superstructure receives mobile load or the time spent is done in little shake, it can drive bearing top board 1 and stainless steel slide plate 2, and friction plate 3 is done less displacement motion relatively, and frictional force is by the friction factor decision of friction pair material (stainless steel slide plate 2---friction plate 3); And do the time spent when superstructure receives big shake, and stainless steel slide plate 2 relative friction plates 3 are done than the big displacement quantity motion, and this moment, frictional force still determined that by the friction factor of friction pair material (stainless steel slide plate 2---friction plate 3) friction plate 3 is connected with bearing intermediate plate 4.Ignore the minor impact of other factorses such as sliding velocity to frictional force; Bearing is receiving under two kinds of operating modes of mobile load and big shake; Friction pair material does not become, so the frictional force of bearing is almost constant, and satisfied not the variable requirement of frictional force that structure proposes bearing: mobile load or little shake effect undersetting frictional force are little; Big shake effect undersetting frictional force is big, and the hysteresis loop of traditional bearing is as shown in Figure 2.
Summary of the invention
The object of the invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of method simple, reliable, make the variable new method of the horizontal frictional force of bearing.
The object of the invention can be realized through following technical scheme:
A kind of variable method of the horizontal frictional force of bearing that makes; Stainless steel slide plate in the support friction pair is placed the bottom; On the top of stainless steel slide plate two friction plates that friction factor is different are set, the less friction plate of friction factor is arranged in the center, and the friction plate that friction factor is bigger is arranged in the outside.
When the frictional contact surface of bearing produced less displacement, the less friction plate of friction factor worked, and the frictional force that bearing produces is less.
When the frictional contact surface of bearing produced bigger displacement, the friction plate that friction factor is bigger worked, and the frictional force that bearing produces is bigger.
Can give full play to the friction function of shock insulation of bearing under different applying working conditions with the commensurate structure demand through the method, promptly mobile load or little shake effect undersetting frictional force are little, thereby make the bearing horizontal displacement big, fully carry out friction energy-dissipating; Big shake effect undersetting frictional force is big, thereby reduces its horizontal displacement amount, prevents the bearing beam phenomenon that falls.
Described friction plate adopts two or more friction factor number of various materials.
Described friction plate is arranged at the top of friction pair.
Described friction template is three-back-shaped or cirque structure.
Compared with prior art, the present invention has following characteristics:
(1) when superstructure received mobile load or varying strength geological process power, the frictional force that bearing produced changed because of the variation of its horizontal displacement, realized the variable requirement of bearing frictional force.
(2) this technical scheme is simple, reliable, easy regulates, and can make bearing produce corresponding seismic response effect through the friction plate of different coefficients of friction and performance is set.

Embodiment
A kind of variable new method of the horizontal frictional force of bearing that makes, this method is that the stainless steel slide plate 2 in the support friction pair is placed the bottom, with bearing intermediate plate 4 welding, and in the bearing top board, glueds joint and embeds the different friction plate 31 of friction factor (friction factor is μ
1) and friction plate 32 (friction factor is μ
2), μ wherein
1＜μ
2, friction plate 31 is arranged in the center, and friction plate 32 is arranged in the outside.Bearing intermediate plate 4 embeds in the base-plate 5, and base-plate 5 is connected with the works 6 of bottom, and bearing top board 1 is connected with superstructure.Its structure of new bearing is as shown in Figure 3.When structure receive vehicle-mounted, wind carries or the time spent is done in little shake etc., less horizontal displacement takes place in the bearing frictional contact surface, this moment, only friction plate 31 worked, the frictional force that bearing produces is also less; Do the time spent when structure receives big shake, the bearing frictional contact surface produces bigger horizontal displacement, friction plate 32 participation effects this moment, and the frictional force that bearing produces is also bigger.Bearing under mobile load or the little shake effect and the hysteresis loop under big shake effect see Fig. 4 and Fig. 5.Therefore, this scheme can be given full play to the friction function of shock insulation of bearing under different applying working conditions with the commensurate structure demand.
