Description
Technical field
The utility model belongs to bridge attachment technique field, particularly a kind of water-proof spherical bearing being particularly useful for Southwest Mountainous Areas bridge.
Background technology
Spherical bearing because its bearing capacity is large, power transmission evenly, each to advantages such as rotational characteristic are consistent, successively apply on the bridges such as numerous highway bridge, railroad bridge, municipal traffic, achieve good effect.In the bridge construction applied, bridge pier height degree is general not high, or bridge floor is comparatively large relative to pier shaft, after spherical bearing is installed, need not consider at waterproof problem in rainy season, on dustproof construction, just done some process.Dustproof construction mainly seals bearing flat frictional pair and sphere friction pair, normally rubber tile is set between spherical bearing upper and lower seat board or seat board in bearing and corresponding friction pair are closed by other nonmetals sealed skirt, to avoid in the secondary interface of bearing extraneous dust engaging friction in running, cause friction pair to wear and tear aggravation, thus shorten bearing application life.
In the bridge construction of Southwest Mountainous Areas, by the influence of topography, bridge pier shaft is usually higher, and Southwest Mountainous Areas belongs to subtropical zone monsoon climate impact simultaneously, and annual rainfall is large, reaches more than 1000mm, and average annual humidity also reaches more than 80% simultaneously, and by certain Acid Rain Effect.Rainy time, rainwater is easy to drop on bearing and also may enters bearing inside, easily causes spherical bearing corrosion, and when particularly there is certain acid rain, the corrosion of bearing can aggravate further, finally causes bearing premature degradation.
Therefore, be necessary that developing a kind of good water-proof effect, structure is simply easy to process and is applicable to Southwest Mountainous Areas bridge permanent seal cooling spherical bearing.
Utility model content
The utility model is for Southwest Mountainous Areas structural characteristic of bridge and environmental quality, for solving bearing waterproof problem when rainy, a kind of spherical bearing with water-proof function is provided, the durability of spherical bearing in the environment of Southwest Mountainous Areas can be ensured, thus overcome the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the utility model is so a kind of water-proof spherical bearing, and it comprises upper base plate, middle seat board and lower seat board, and three layers of seat board are superimposed mutually, and the slip that can misplace mutually, lower seat board is fixed on pier; Planar slide friction pair is formed by the nonmetal slide plate of plane and plane metal slider between upper base plate and middle seat board, form sphere sliding friction pair by sphere metal slider and the nonmetal slide plate of sphere between middle seat board and lower seat board, this technology is conventional prior art; Innovation of the present utility model is, its surrounding is provided with the waterproof sealing skirt of its integral coating from the side, this waterproof sealing skirt is the skirt structure with the upper edge of opening, the lower edge of opening, the upper edge of this waterproof sealing skirt is arranged on spherical bearing upper base plate four perisporium, and waterproof sealing skirt lower is along seat board under collar and be fixed on pier.Due to waterproof sealing skirt by the side integral coating of this water-proof spherical bearing live, can effectively prevent bearing in use rainwater enter bearing inside cause the problems such as the corrosion of bearing.
Further, aforesaid waterproof sealing skirt is coated with by polyethylene waterproof material or polyvinyl acetate waterproofing materials or acrylate the structure that membranous type waterproof roll or polyurethane waterproof material make, and such material has certain pliability, and water resistance is better.
Because this waterproof sealing skirt of the present utility model adopts skirt structure, so the present invention also needs the problem solved to be exactly the problem of the fixed form on the lower edge (namely train of dress) of this waterproof sealing skirt in the process implemented, in order to ensure good sealing effectiveness, the lower of waterproof sealing skirt can fixedly secure on pier along needs, also need to be convenient to dismounting and change, therefore, the utility model provides following several scheme:
The first is provided with for being fixed in and the cranse on the pier of lower seat board junction, by cranse, the lower of waterproof sealing skirt is combined in lower seat board surrounding place side face along hoop, thus fixing on pier.The second is that the lower edge of waterproof sealing skirt is provided with for being shunk the contraction tension rope of tension on four perisporiums of described lower seat board, equally also the lower of waterproof sealing skirt can be strained and fixed along shrinking by this contraction tension rope.The third be waterproof sealing skirt lower edge by one circle bar magnet be adsorbed on four perisporiums of lower seat board.Certainly, also can adopt other mode easily, the lower edge of such as waterproof sealing skirt connects or is bonded on four perisporiums of lower seat board, and the mode of connection can be the modes such as binding.
Compared with prior art, the utility model is particularly suitable for using in the rainy environment in Southwest Mountainous Areas, effectively can ensure the application life of highway bridge spherical bearing.And the waterproof construction that the utility model provides is simple, be easy to make, cost is low, and waterproof effect is remarkable, is worthy to be popularized.
