Abstract
The utility model discloses a plate type rubber support seat, which comprises anchor bars, a support seat plate, a stainless steel plate and a plate type support seat matrix. Four anchor bars are fixed at four corners of the upper surface of the support seat plate; the stainless steel plate is welded on the bottom surface of the support seat plate and is in contact fit with the plate type support seat matrix; and a dustproof device is arranged on the side of the support seat plate. According to the plate type rubber support seat, the mounting quality and the service life of the support seat are ensured, and the manufacturing cost of a bridge is greatly reduced simultaneously; and the plate type rubber support seat has a certain economic benefit.
Description
Technical field
The utility model belongs to the bridge technology field, is specifically related to a kind of laminated rubber bearing that is used for bridge.
Background technology
Its major defect of supporting steel plate of highway in China bridge laminated rubber bearing employing at present is as follows: 1, the bearing of this structural shape needs carry out the integral body assembling in manufacturing works, can not take apart in the installation process, as carrying out dismounting, then damage corrosion resistant plate and bearing matrix easily at building-site.Gu the type bearing is not suitable for the precast beam body, in the beam body of anchor bolt on the bearing need being nuzzled during because of the system beam.2, anchor bolt needs to carry out perforate on the pier pinner down, grouting then, and need after the beam body is installed and adjusted to the right place, just can build.This mode of operation more complicated, difficulty of construction is bigger under the less situation in board-like height of support space.3, because laminated rubber bearing adopts rubber and steel plate to be formed by stacking, thus the bigger horizontal force of bridge superstructure itself can not be born, Gu the guide pad practical significance of this structural shape upper base plate is little.And highway bridge generally is provided with anti-fall girder apparatus, and the horizontal force of bridge can transmit by this device.4, adopt this up and down bearing of base plate structure pattern, be not easy in bridge construction process to guarantee that each bearing is evenly stressed, if bearing unbalance stress or be difficult for adjusting when coming to nothing phenomenon.5, because the laminated rubber bearing whole height is less, the operating space was limited when solid its installed, and as adopting screw connection dust guard, then can't install.
Highway in China bridge laminated rubber bearing adopts the transportation industry standard to design and produce, and this structural shape steel using amount is bigger, and more complicated is installed.By investigation to China's many speedway laminated rubber bearings mode of occupation, find that most of user does not adopt the supporting steel plate of bearing of industry standard regulation to be provided with, but adopt the mode of self-control steel plate to carry out the installation of bridge pad, the basic like this quality that can't guarantee after bearing is installed.Most of unit in charge of construction does not smear silicone grease oil yet and dust guard is installed simultaneously, has caused the wearing and tearing of abutment surface tetrafluoro slide plate, influences the application life of bearing.
In order to better meet the user installation instructions for use, we need develop a kind of New-type plate neoprene bearing, can avoid above problem preferably.
The utility model content
The purpose of this utility model provides a kind of laminated rubber bearing, and this bearing can guarantee installation quality and application life, can also reduce the manufacturing cost of bridge simultaneously greatly, and simple in structure, easy accessibility.
The utility model is that the technical scheme that is adopted that achieves the above object is: a kind of laminated rubber bearing, comprise dowel, seat board, corrosion resistant plate and board-like bearing matrix, it is characterized in that described each angle of seat board upper surface is fixed with dowel, concrete is fixes four dowels on four jiaos of seat board upper surfaces, prop up the seat board bottom surface and be fixed with corrosion resistant plate, the corrosion resistant plate bottom surface contacts with board-like bearing matrix; Also be provided with dust guard on described the seat board side.
Above-mentioned corrosion resistant plate is welded on a seat board bottom surface, and described board-like bearing matrix surface is a polyfluortetraethylene plate, and described dowel is threaded in the bearing plate top surface.
Therefore the utlity model has following advantage: 1, the bearing of this structural shape need not to assemble in factory, and bearing seat board and matrix can separate shipping, when making beam, the bearing seat board is placed in the beam phantom plate directly build.2, since rubber and concrete friction factor (〉=0.3) much larger than the friction factor (≤0.06) between tetrafluoro slide plate and corrosion resistant plate, so can cancel seat board under the bearing according to actual conditions.3, occur coming to nothing in installation process as bearing or during big bias voltage phenomenon, can fill epoxy mortar easily between bearing matrix and pinner and adjust, this mode has reduced the difficulty of construction of unit in charge of construction.4, the weight of the supporting steel plate of this bearing reduces greatly, can better guarantee the bearing installation quality when simplifying construction technology, can effectively reduce the manufacturing cost of bridge.Therefore the utility model has guaranteed the installation quality and the application life of bearing, reduces the manufacturing cost of bridge simultaneously greatly.
Description of drawings
Fig. 1 is that the utility model partly cuts open structural representation
Fig. 2 is the vertical view of Fig. 1
Among the figure: the 1-dowel; 2-props up seat board; The 3-dust guard; The 4-corrosion resistant plate; The board-like bearing matrix of 5-.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further: as shown in Figure 1, 2: laminated rubber bearing comprises dowel 1, seat board 2, corrosion resistant plate 4 and board-like bearing matrix 5.The fixing dowel 1 at each angle of seat board 2 upper surfaces, concrete is fixes four dowels 1 on four jiaos of seat board 2 upper surfaces, prop up fixedly corrosion resistant plate 4 of seat board 2 bottom surfaces, and corrosion resistant plate 4 bottom surfaces contact board-like bearing matrix 5 and cooperatively interact.Also be provided with dust guard 3 on described seat board 2 sides.Aforementioned corrosion resistant plate 4 is to be welded on seat board 2 bottom surface.Board-like bearing matrix 5 surfaces are polyfluortetraethylene plates.Dowel 1 is to adopt to be threaded in seat board 2 end face.The distortion of beam body is exactly by seat board 2 and is welded on the corrosion resistant plate 4 of bottom surface and the horizontal movement of bearing is satisfied in the polyfluortetraethylene plate generation relative displacement on board-like bearing matrix 5 surfaces.
