Abstract
The invention discloses a kind of self-balancing sheet-type support, it is characterized in using the laminated rubber bearing for being provided with spring, and be fixed by crab-bolt and be arranged in the middle of upper and lower bearing steel plate, the laminated rubber bearing is the cylinder of circular or rectangle, and its center is provided with axial mounting hole；The spring is arranged in mounting hole and is integrated with laminated rubber bearing, and the pretightning force of spring and laminated rubber bearing is adjusted by crab-bolt, realizes the self-balancing of bearing stress state.The present invention is compared with prior art with while meeting resistant slide performance requirement, Planar Mechanisms influence is produced without the reasonable deformation of limitation bearing serviceability limit stage and on beam body and bearing horizontal displacement, the anti-slipping property that stress level and the bearing entirety of spring and laminated rubber bearing are adjusted by crab-bolt can be to meet actual loading demand, improve bearing entirety anti-slipping property energy, it is especially suitable for being used on the resistant slide bearing of Short/Medium Span Bridge, simple structure, it is easy for installation.
Description
Technical field
The present invention relates to technical field of bridge engineering, especially a kind of self-balancing for adapting to Short/Medium Span Bridge resistant slide
Sheet-type support.
Background technology
Common laminated rubber bearing 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, account 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 to solve problems typically all using enhancing bearing and the bonding of beam body
Performance and enhancing bearing level are to rigidity.
The problem that prior art is present is to also limit bearing while bearing anti-slipping property energy is strengthened normally to use rank
The reasonable deformation of section, easily produces Planar Mechanisms to beam body.
The content of the invention
A kind of self-balancing sheet-type support that the purpose of the present invention is directed to the deficiencies in the prior art and designs, using setting bullet
The laminated rubber bearing of spring, and the pretightning force of bearing is adjusted by crab-bolt, spring and laminated rubber bearing is formed common compression, it is real
The self equilibrium systemses of existing bearing, optimize the stress state of laminated rubber bearing, it is ensured that pedestal frictional force is meeting anti-slipping property
Can require, Planar Mechanisms influence is produced without the horizontal displacement on bearing, substantially increase bearing entirety anti-slipping property energy, structure letter
Single, easy for installation, preferably resolving prior art and also limit bearing while bearing anti-slipping property energy is strengthened normally makes
With the reasonable deformation in stage and easily to the problem of beam body generation Planar Mechanisms.
The object of the present invention is achieved like this：A kind of self-balancing sheet-type support, including by laminated rubber bearing with it is upper and lower
The bearing of bearing steel plate composition, be characterized in being fixed by crab-bolt using the laminated rubber bearing for being provided with spring be arranged on,
In the middle of undersetting steel plate, the laminated rubber bearing is the cylinder of circular or rectangle, and its center is provided with axial mounting hole；It is described
Spring is arranged in mounting hole and is integrated with laminated rubber bearing, and the pretension of spring and laminated rubber bearing is adjusted by crab-bolt
Power, realizes the self-balancing of bearing stress state.
The resilient dust-proof sleeve of spring peripheral hardware.
The present invention has while improving and meeting resistant slide performance requirement compared with prior art, without limitation bearing
The reasonable deformation of serviceability limit stage and Planar Mechanisms influence is produced on beam body and bearing horizontal displacement, spring is adjusted by crab-bolt
The anti-slipping property overall with the stress level and bearing of laminated rubber bearing can greatly improve bearing to meet actual loading demand
Overall anti-slipping property energy, is especially suitable for the use of Short/Medium Span Bridge resistant slide bearing, and simple structure is easy for installation, manufacture
Low cost.
Brief description of the drawings

Fig. 2 is the A-A profiles of Fig. 1；
Fig. 3 is concrete application schematic diagram of the present invention.
Specific embodiment
Refering to 1 ~ accompanying drawing of accompanying drawing 2, the present invention is made up of laminated rubber bearing 6 with upper bracket steel plate 1 and undersetting steel plate 2,
The laminated rubber bearing 6 is the cylinder of circular or rectangle, and its center is provided with axial mounting hole 7；The spring 4 is arranged on peace
It is integrated in dress hole 7 and with laminated rubber bearing 6；The resilient dust-proof sleeve 5 of the peripheral hardware of the spring 4；The spring 4 of being provided with
Laminated rubber bearing 6 is fixed by crab-bolt 3 and is arranged in the middle of upper bracket steel plate 1 and undersetting steel plate 2, and is adjusted by crab-bolt 3
The pretightning force of spring 4 and laminated rubber bearing 6, 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 is common with bridge beam body 8 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 with spring 4, then lifts to installation site bridge beam body 8,
Crab-bolt 3 after correction bridge beam body 8 position is errorless, screws the nut of crab-bolt 3, until crab-bolt through the bolt hole of bearing lower steel plate 2
3 reach default tension, complete bearing and install.
The present invention screws generation pretightning force using crab-bolt 3 by nut, and pretightning force is by the spring 4 and board-like rubber that are pressurized
Bearing 6 is balanced, and spring 4 and the pressure of laminated rubber bearing 6 are by both ratio of rigidity distribution, and it is right to reduce that crab-bolt 3 answers direction across bridge to arrange
The rotational restraint of bearing, spring 4 as compression body on bearing rotating property and level to detrusion substantially without influence.The bullet
The common stress of association that spring 4 is formed with laminated rubber bearing 6, and can be by adjusting its ratio of rigidity to meet actual loading demand
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
Regulation support stiffness, stress state and anti-slipping property energy, it focuses on crab-bolt 3 as tension member, spring 4 and board-like rubber
The bearing self equilibrium systemses of 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 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 crab-bolt 3 adjusts the vertical rigidity of spring 4 and laminated rubber bearing 6, by adjust vertical force with
Meeting bearing anti-slipping property energy, but do not form Planar Mechanisms to deformation to bearing level influences.
Simply the present invention is further illustrated above, and is not used to limit this patent, and all is equivalence enforcement of the present invention,
It is intended to be limited solely by within the right of this patent.
