PROBLEM TO BE SOLVED: To provide a joint apparatus for a gradient road surface that can absorb the swaying due to the earthquake without causing the tip part of a joint plate to crash into obstructions or to cross over boundaries when a joint part becomes narrow, even if the obstructions and the boundaries are present in the vicinity of the tip part of the joint plate.SOLUTION: A joint apparatus for a gradient road surface is constituted of: a slide support recess formed in one road surface of left and right road surfaces having a gradient provided through a joint part; a support plate slidably provided in the slide support recess; one joint plate with a rear end attached to an anti-joint side of the slide support recess, and with a tip part supported in the support plate; and the other joint plate with the rear end supported by the other road surface of the left and right road surfaces, and with the tip part supported by the support plate. When the joint part swings in the direction narrowed by an earthquake, the one joint plate and the other joint plate are characterized in that the swaying can be absorbed without colliding the obstructions on the road surface or crossing over the boundaries.SELECTED DRAWING: Figure 1
【課題】 本発明は目地プレートの先端部付近に障害物や境界が存在する場合でも、目地部が狭くなった際に目地プレートの先端部が障害物に激突したり、境界を越えることなく地震による揺れ動きを吸収することができる勾配路面用目地装置を得るにある。【解決手段】 目地部を介して設けられた勾配を有する左右の路面の一方の路面に形成されたスライド支持凹部と、該スライド支持凹部にスライド可能に設けられた支承プレートと、前記スライド支持凹部の反目地部側に後端部が取り付けられ、前記支承プレートに先端部が支持された一方の目地プレートと、前記左右の路面の他方の路面に後端部が支持され、先端部が前記支承プレートに支持された他方の目地プレートとで構成され、地震によって目地部が狭まる方向に揺れ動いた時に、前記一方の目地プレートおよび他方の目地プレートは、前記路面上の障害物に衝突あるいは境界を越えることなく揺れ動きを吸収できることを特徴とする。【選択図】 図１
