Bridge lead core rubber support sliding assembly of the present utility model comprises the upper junction plate and the lower connecting plate of fixedlying connected with the lead core rubber support body, also comprises sliding plate; Described sliding plate and upper junction plate or and lower connecting plate is oppositely arranged and be slidingly matched with its along continuous straight runs.
Further, described sliding plate and upper junction plate or and lower connecting plate between cooperate and form the linear slide bearing arrangement by slide plate slides is set;
Further, described upper junction plate or and lower connecting plate and sliding plate facing surfaces groove is set, described slide plate is embedded in the groove, the upper surface of slide plate protrudes from the junction plate surface;
Further, described sliding plate is provided with block respectively downwards and forms slippage slot along horizontal two ends, described upper junction plate or and lower connecting plate and slide plate be positioned at slippage slot and be slidingly matched with it;
Further, described sliding plate two ends longitudinally are provided with vertical block respectively downwards, described two vertical blocks and upper junction plate or and the vertical two ends of lower connecting plate the slippage spacing is set;
Further, the surface that cooperates with slide plate slides of described sliding plate is downward convex plane;
Further, described slide plate is polyfluortetraethylene plate, filled polytetrafluoroethylene plate or nylon sheet.
The beneficial effects of the utility model: bridge lead core rubber support sliding assembly of the present utility model, adopt slipping mechanism to be arranged on existing lead core rubber support, after construction and later stage when circumstance of temperature difference occurring, lead core rubber support can overcome in the normal use because the distortion of the temperature difference, concrete shrinkage and creep generation by horizontal sliding, lead for retractable pencil can not surrendered in normal use, avoid lead core rubber support to cause fatigue damage, and stronger deformability can be arranged when earthquake takes place, play due anti seismic efficiency.
