Description
Technical field
The utility model is related to technical field of bridge engineering, especially it is a kind of adapt to Short/Medium Span Bridge resistant slide from
Balance sheet-type support.
Background technology
Common laminated rubber bearing is because the reason such as its comprehensive cost is cheap and construction method is cheap is in science of bridge building, especially
It is to be used widely in Short/Medium Span Bridge engineering.Two important indicators of common laminated rubber bearing type selecting are respectively bearing
Maximum vertical bearing capacity and minimum resistant slide bearing capacity, are accounted for for part deadweight relatively light or serviceability limit stage variable load effect
The larger Short/Medium Span Bridge of standard combination load effect, bearing maximum vertical bearing capacity and minimum resistant slide bearing capacity often without
Method meets the requirements of type selecting of bearing simultaneously, and existing product is solution problems typically all using enhancing bearing and the bonding of beam body
Performance and enhancing bearing level are to rigidity.
The problem of prior art is present is that also limit bearing while bearing anti-slipping property energy is strengthened normally uses rank
The reasonable deformation of section, easily produces Planar Mechanisms to beam body.
Utility model content
A kind of self-balancing sheet-type support that the purpose of this utility model is in view of the shortcomings of the prior art and designed, using setting
Put the laminated rubber bearing of spring, and the pretightning force of bearing adjusted by crab-bolt, make spring and laminated rubber bearing formed it is common by
Pressure, realizes the self equilibrium systemses of bearing, optimizes the stress state of laminated rubber bearing, it is ensured that pedestal frictional force is to meet antiskid
Performance requirement is moved, Planar Mechanisms influence is produced without the horizontal displacement on bearing, the overall anti-slipping property energy of bearing, knot is substantially increased
Structure is simple, easy for installation, preferably resolves prior art and also limit bearing just while bearing anti-slipping property energy is strengthened
The problem of reasonable deformation of normal service stage and the easy generation Planar Mechanisms to beam body.
What the purpose of this utility model was realized in：A kind of self-balancing sheet-type support, including by laminated rubber bearing with
The bearing of upper and lower bearing steel plate composition, is characterized in using the laminated rubber bearing provided with spring, and is fixed and sets by crab-bolt
Put in the middle of upper and lower bearing steel plate, the laminated rubber bearing is the cylinder of circular or rectangle, installation of its center provided with axial direction
Hole；The spring is arranged in mounting hole and is integrated with laminated rubber bearing, and adjusts spring and laminated rubber bearing by crab-bolt
Pretightning force, realize the self-balancing of bearing stress state.
The flexible dust-proof sleeve of the spring peripheral hardware.
The utility model has while improving and meeting resistant slide performance requirement compared with prior art, without limiting
The reasonable deformation of bearing serviceability limit stage and Planar Mechanisms influence is produced on beam body and bearing horizontal displacement, adjusted by crab-bolt
The overall anti-slipping property of the stress level and bearing of spring and laminated rubber bearing can be greatly improved with meeting actual loading demand
The overall anti-slipping property energy of bearing, is especially suitable for the use of Short/Medium Span Bridge resistant slide bearing, simple in construction, easy for installation,
Manufacturing cost is low.
Brief description of the drawings

Fig. 2 is Fig. 1 A-A profiles；
Fig. 3 is the utility model concrete application schematic diagram.
Embodiment
Refering to 1 ~ accompanying drawing of accompanying drawing 2, the utility model is by laminated rubber bearing 6 and 2 groups of upper bracket steel plate 1 and undersetting steel plate
Into the laminated rubber bearing 6 is the cylinder of circular or rectangle, mounting hole 7 of its center provided with axial direction；The spring 4 is set
It is integrated in mounting hole 7 and with laminated rubber bearing 6；The flexible dust-proof sleeve 5 of the peripheral hardware of spring 4；It is described to be provided with bullet
The laminated rubber bearing 6 of spring 4 is fixed by crab-bolt 3 to be arranged in the middle of upper bracket steel plate 1 and undersetting steel plate 2, and by crab-bolt 3
The pretightning force of spring 4 and laminated rubber bearing 6 is adjusted, to realize the self-balancing of bearing stress state.
It is refering to accompanying drawing 3, upper bracket steel plate 1 and crab-bolt 3 and bridge beam body 8 is common prefabricated, then bearing lower steel plate 2 is placed in
Installation site, laminated rubber bearing 6 is placed in the center of bearing lower steel plate 2, and the dust-proof sleeve 5 of elasticity is arranged on into spring
It is positioned over outside 4 and together in the mounting hole 7 of laminated rubber bearing 6, then lifts bridge beam body 8 to installation site with spring 4,
Crab-bolt 3 passes through the bolt hole of bearing lower steel plate 2, after correction bridge beam body 8 position is errorless, screws the nut of crab-bolt 3, until crab-bolt
3 reach default tension, complete bearing and install.
The utility model screws generation pretightning force using crab-bolt 3 by nut, and pretightning force is by the spring 4 that is pressurized and board-like
Rubber support 6 is balanced, and spring 4 and the pressure of laminated rubber bearing 6 are by both ratio of rigidity distribution, and crab-bolt 3 answers direction across bridge arrangement to subtract
The small rotational restraint to bearing, spring 4 as compression body on bearing rotating property and level to detrusion substantially without influence.Bullet
Spring 4 and the common stress of association of the formation of laminated rubber bearing 6, and actual loading demand can be met by adjusting its ratio of rigidity
Stress level, improve the overall anti-slipping property energy of bearing.By crab-bolt 3, spring 4 and the synergy of laminated rubber bearing 6 with
Support stiffness, stress state and anti-slipping property energy are adjusted, it is tension member, spring 4 and board-like rubber that it, which focuses on crab-bolt 3,
The bearing self equilibrium systemses for the pressure containing part composition that bearing 6 is integrated, by adjusting the diameter of crab-bolt 3, the rigidity of spring 4 and board-like rubber
The physical dimension of bearing 6 is to control the integral rigidity of bearing, by adjusting the ratio of rigidity of spring 4 and laminated rubber bearing 6 to control
Sheet-type support stress state.The vertical rigidity of the crab-bolt 3 regulation spring 4 and laminated rubber bearing 6, by adjust vertical force with
Bearing anti-slipping property energy is met, but to deformation Planar Mechanisms influence is not formed to bearing level.
Simply the utility model is further described above, and is not used to limit this patent, all is the utility model
Equivalence enforcement, is intended to be limited solely by within the right of this patent.
