Abstract
The utility model relates to a bridge shock-proof supporting seat with a cylindrical surface, which comprises an upper cover, a base, a stainless steel plate arranged between the upper cover and the base, a column core and a polytetrafluoroethylene plate, wherein the upper cover is matched with the outer edge of the base in a detachable way, and the stainless steel plate and the polytetrafluoroethylene plane plate are orderly laminated between the upper surface of the column core and the lower surface of the upper cover from top to bottom; the longitudinal section of the lower surface of the column core is a convex cambered surface, and the longitudinal section of the upper surface of the base is a concave cambered surface; a polytetrafluoroethylene cylindrical surface plate is arranged between the column core and the base. The utility model overcomes the defects that the rotation flexibility in the prior art is poor, the stress of the supporting seat is easily deviated from the central position of the bottom of the supporting seat, the tensile property of the supporting seat is poor, etc. The utility model has the advantages of simple structure, flexible rotation, shock resistance, etc.
Description
The utility model relates to a kind of bridge earthquake resistance Column face bearing.
Present existing bridge Column face bearing is generally the branch body structure, exists the rotation very flexible, the stressed center of easily departing from rest base of bearing, and the tensile property of bearing is poor, and deficiencies such as disintegration easily take place when earthquake.
The bridge earthquake resistance Column face bearing that the purpose of this utility model is to provide a kind of rotates flexibly, tensile property is good is to overcome the deficiency of prior art.
Overall structure of the present utility model is:
The bridge earthquake resistance Column face bearing comprises loam cake 1, base 6, is arranged at corrosion resistant plate 2, post core 4, polyfluortetraethylene plate between loam cake 1 and the base 6; Described loam cake 1 adopts active the cooperation with the outward flange of base 6, folded successively from top to bottom corrosion resistant plate 2 and the polytetrafluoroethylene (PTFE) surface plate 3 of being shaped between post core 4 upper surfaces and loam cake 1 soffit, the longitudinal section of post core 4 soffits is a convex globoidal, the longitudinal section of base 6 upper surfaces is a cancave cambered surface, is provided with polytetrafluoroethylene (PTFE) pole panel 5 between post core 4 and the base 6.
Concrete structure of the present utility model also has:
The outward flange of the lower edge of loam cake side plate 7 and base 6 is the coupling type matched in clearance.
Polytetrafluoroethylene (PTFE) surface plate 3 is flush-mounted in post core 4 upper surfaces, and the outward flange of the upper surface of base 6 is provided with the convex edge, and this convex edge and post core 4 soffits and polytetrafluoroethylene (PTFE) pole panel 5 adopt concavo-convex matched in clearance.
Corrosion resistant plate 2 is fixedlyed connected with loam cake 1, between corrosion resistant plate 2 and the polytetrafluoroethylene (PTFE) surface plate 3 for being slidingly connected.
Polytetrafluoroethylene (PTFE) surface plate 3 is fixedlyed connected with post core 4.Between post core 4 and the polytetrafluoroethylene (PTFE) pole panel 5 for being slidingly connected, between polytetrafluoroethylene (PTFE) pole panel 5 and the base 6 for fixedlying connected.
The obtained technological progress of the utility model is that this bearing overall structure is simple, the post core of bearing adopts face of cylinder load, rotate flexibly, make the suffered pressure of bearing point to the center of bearing lower plate all the time, the loam cake side plate lower end of bearing curves inwardly simultaneously, form hook with the projection of base, make bearing can bear pulling force, thereby have function of seismic resistance.
Accompanying drawing of the present utility model has:
