Abstract
The utility model discloses a large deflection pot rubber bearing, including support crab -bolt, upper bracket board, stainless steel slide, middle welt, rubber seal, polyfluortetraethylene plate, steel lock ring circle, chloroprene rubber board, bottom suspension bedplate. Bottom suspension bedplate upper portion is equipped with the echelonment recess, and the rubber slab designs into corresponding special shape, embedded in the recess in. The rubber slab diameter slightly is lighter than the interior warp of bottom suspension bedplate basin. The rubber slab is equipped with firm lock ring circle with contact department of steel basin. Polyfluortetraethylene plate is partly embedded in middle welt, and some exceeds welt and corrosion resistant plate friction sliding. The utility model discloses can satisfy normal working condition and can satisfy bigger corner requirement than the thickness relatively to each item performance requirement, especially peripheral rubber slab of support down, and middle pelvic floor can bear bigger vertical load than the thickness relatively, improves the life -span of support.
Description
Technical field
This utility model relates to a kind of big corner pot rubber bearing, is mainly used on the bridges such as road and rail.
Background technology
Pot rubber bearing is the bridge pad of exploitation at the external end of the fifties, it is with the rubber slab pressure-bearing being arranged in steel basin and rotation, adapt to the displacement request of bridge with the planar slide between polyfluortetraethylene plate and corrosion resistant plate, along with developing rapidly of bridge technology, different types of rridges occur as soon as.Particularly curved bridge, the rotating property to bearing that is born of curved bridge is had higher requirement, and the thickness of rubber slab has certain limitations, wanting the requirement making existing pot rubber bearing adapt to big corner, existing structure does not the most adapt to its function, it is necessary to carry out the improvement of structure.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point, it is provided that a big corner pot rubber bearing, has bigger rotation radian, more preferable rotating property, and has higher vertical bearing capacity.
The technical scheme that this utility model is used for achieving the above object is as follows: a kind of big corner pot rubber bearing, including bearing crab-bolt, upper bracket plate, rustless steel slide plate, middle liner plate, rubber seal, polyfluortetraethylene plate, steel lock ring circle, neoprene plate, lower support plate.It is characterized in that undersetting steel basin is type, corresponding rubber slab is concave shape.Between lower support plate and plane slide plate, rubber seal is set.Rubber slab surrounding arranges sealing ring.It is provided with rubber seal between basin ring and the plane slide plate of end basin.
Steel basin described in this utility model be shaped as type, between 1st/to two/3rds of a diameter of steel basin internal diameter of bossing.
Pressure-bearing rubber slab described in this utility model is concave shape, and thickness is about to the ten/10ths 1/5th of diameter.
The lower straight of the middle liner plate described in this utility model is through being slightly less than the internal diameter (about 1mm) of basin.
Steel lock ring circle described in this utility model is annular, and thickness is 4mm.
Politef plate thickness described in utility model is 4-8mm, and bottom is embedded in the partially larger than 2.5mm of middle liner plate, exceeds patch portion and is about 1.5-3mm.
Rubber seal described in this utility model makes pressure-bearing rubber slab be in artesian condition.
By changing the shape of the shape at the bottom of basin and pressure-bearing rubber slab in this utility model, making pot rubber bearing have bigger corner, rotating property is improved, and can bear the requirements of vertical load and displacement reliably, structure is relatively easy rationally, has the highest using value.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further: as shown in Figure 1: include bearing crab-bolt 1, upper bracket plate 3, rustless steel slide plate 4, middle liner plate 5, rubber seal 6, polyfluortetraethylene plate 7, steel lock ring circle 8, pressure-bearing rubber slab 9, lower support plate 10.Rubber slab 9 is embedded in undersetting 10 steel basin, edge be press against by steel lock ring circle 8, middle liner plate 5 thereon some in steel basin, another part contacts with polyfluortetraethylene plate 7, a politef part is embedded in middle liner plate 5, top contacts with plane slide plate, and plane slide plate is fixed with upper bracket plate 3.Lower support plate 10 uses the steel basin of cast steel or Plate Welding, is used for retraining the deformation of pressure-bearing rubber slab, and the thickness of basin ring determines according to lateral pressure.Pressure-bearing rubber slab 9 is in three-dimensional stress state, has the function of similar liquids in steel basin, rotates flexibly, and thickness is to the ten/10ths 1/5th of diameter.Steel lock ring circle 8 is annular lock ring circle, and its thickness is 4mm, is used for preventing rubber destruction peripherally.Middle liner plate 5 is between polyfluortetraethylene plate 7 and polyfluortetraethylene plate 7, and middle liner plate bottom embeds in undersetting steel basin, is slightly less than steel basin internal diameter 1mm, and liner plate top arranges groove, in order to place polyfluortetraethylene plate 7.Polyfluortetraethylene plate 7 thickness is 4-8mm, and bottom is embedded in the partially larger than 2.5mm of middle liner plate 5, exceeds patch portion and is about 1.5-3mm.Lower support plate 10 uses steel plate, surface rustless steel slide plate 4 after the upper 2mm of argonaut welding welding.
