Abstract
The utility model discloses a V-shaped guide rail structure unidirectional support which comprises a support upper part, a sliding pair and a support lower part. The sliding pair is positioned between the support upper part and the support lower part; the sliding pair comprises an upper component and a lower component; the upper component of the sliding pair is fixedly connected with the support upper part; the lower component of the sliding pair is fixedly connected with the support lower part; and the upper component and the lower component of the sliding pair are matched positive V-shaped guide rail structures or inverted V-shaped guide rail structures. According to the utility model, an existing guide structure is simplified, horizontal stress is more stable and load impact is reduced; meanwhile, in the non-sliding direction, under the action of outside horizonal acting forces which are over a designed horizontal force, such as earthquakes and the like, the V-shaped guide rail structures can enable slippage to be generated between the support upper part structure and the support lower part structure in the horizontal direction, lifts up a bridge, has an effect of storing potential energy and takes a certain buffering effect so as to reduce the damage which is possibly caused to the support and the bridge under the undesigned working condition.
Description
Technical field
The utility model relates to the parts of Structural Engineerings such as a kind of bridge, building, specifically is a kind of V-way structure one-way type bearing.
Background technology
Bearing is one of parts of being most widely used of current bridge engineering, their effect is that the concentrated counter-force with the beam-ends fulcrum passes to pier more equably, guarantee that simultaneously bridge span structure is when bearing load or variations in temperature, can adapt to the distortion that this variation brings, namely freely rotating with the level of an end of end stretched.The flexible of level mainly adapts to by one-way support, the restriction displacement vertical with flexible direction simultaneously.The guide rail that present one-way type bearing adopts, its vertical carrying and horizontal bearing are orthogonal two planes, and this type guide rail structure is comparatively complicated, and there is certain impact in horizontal bearing.
In the prior art, application number is that 201120030548.2 Chinese utility model patent discloses a kind of railroad bridge with unidirectional sliding-type vibration isolating suspension, comprises upper base plate, vibration isolation rubber body and following seat board; Upper base plate is interlock U-shaped with following seat board, upper and lower seat board two ends have the block of protrusion respectively, constitute horizontal force resistant mechanism, and paste at the guiding stainless steel slide plate on the upper base plate block and the low friction of the guiding slide plate that is embedded on the seat board block down and constitute the guiding friction pair; Vibration isolation rubber body between upper base plate and following seat board has upper sealing plate and following shrouding; The plane stainless steel slide plate that pastes in the upper base plate bottom surface constitutes the planar friction pair with the plane low friction slide plate that is embedded in the upper sealing plate; Following shrouding is connected as a single entity with following seat board.Application number is that 201220045327.7 Chinese utility model patent discloses the horizontal spacing-type shock insulation rubber bearing of a kind of unidirectional slip, upper bracket steel plate and undersetting steel plate are set, a seat body is set between upper bracket steel plate and the undersetting steel plate, seat body comprises laminated rubber, and therebetween is established the multilayer steel plate of putting more energy into; Laminated rubber arranges top steel plate and end steel plate in both sides up and down; The below of undersetting steel plate arranges the lower slider steel plate; The friction slide plate is inlayed in the bottom surface of undersetting steel plate; The end face welding mirror face stainless steel plate of lower slider steel plate; The undersetting steel plate arranges spacing briquetting respectively on the both sides of glide direction on the mirror face stainless steel plate, lower slider steel plate.Above-mentioned existing guiding sliding technology one-way type bearing, structure are comparatively complicated, and there is certain impact in horizontal bearing, is further improved.
The utility model content
The purpose of this utility model is exactly in order to overcome the defective that prior art exists, a kind of simple in structure, the shock-free V-way structure one-way of horizontal bearing type bearing to be provided.
The purpose of this utility model is achieved through the following technical solutions: described V-way structure one-way type bearing, comprise bearing top, sliding pair and bearing bottom, described sliding pair is between bearing top and bearing bottom, sliding pair comprises upper member and lower member, the upper member of described sliding pair is fixedlyed connected with bearing top, the lower member of described sliding pair is fixedlyed connected with the bearing bottom, and the upper member of described sliding pair and lower member are just " V " the shape guide rail structure that cooperatively interacts or " V " shape guide rail structure that falls.
Described V-way structure one-way type bearing can be used for bridge or other construction work.Described sliding pair is V-shaped, and the upper member of described sliding pair and lower member are antifriction material wearing plates such as mirror face stainless steel plate or PTFE, and pairing is used.Described bearing top has the structure that matches with sliding pair with the one side that the bearing bottom is connected with sliding pair.The inclined-plane of " V " shape guide rail structure and the corner dimension between the horizontal plane can be according to the sizes of design level power, and consider that design safety factor designs, and horizontal force is more big, and then angle is more big, its angular range be greater than 0 °, less than 90 °.
Compared with prior art, the utility model has been simplified existing guide frame, is integrated into one group of slide plane that bears vertical load and transverse load simultaneously with bearing one group of vertical load and one group of slide plane bearing horizontal load.Owing to eliminated the horizontal direction gap between the existing guide rail structure slide plane, make level stressed more steady, reduced load impacting, simultaneously, non-glide direction surpasses under the extraneous horizontal applied force of design level power in earthquake etc., the V-way structure can make and produce slippage between bearing superstructure and the substructure in the horizontal direction, and bridge lifted, effect with storage of potential energy, play certain cushioning effect, and then reduce the destruction that bearing may be subjected at off-design behaviour undersetting itself and bridge.
