た。Further, in order to alleviate the noise and the shock when the vehicle is running, the joints (20) (2)
It is conceivable to make the play space (21) between 0) as narrow as possible, but this makes the play space (22) the floor plate (24).
Since it becomes narrower up to (24), the amount of rainwater stored at the time of rainfall decreases and the guiding groove by the sealing material (23) becomes narrower, the introduction into the gutter of the road bridge can not catch up, and even if the amount of rainfall is a little Rainwater overflowed around the play space (22) on the surface and pooled water, which hindered safe driving of the vehicle.

In the joints (20) (20) that are intertwined in a comb shape that are commonly used, the lower end sides (20b) (20b) of the joints (20) (20) are the floorboards (24) (24). ), The floor boards (24) (2) are mounted on the floor boards (24) of the other party.
4) When mounting the joints (20), (20) on the top, the curing concrete (26) falls into the space (25) between the floor plates. Therefore, the lower end sides (20b) of the comb-teeth-shaped protrusions (20c) (20c) of the joints (20) (20)
(20b) A support plate (21) (21) must be provided on the inside to prevent the concrete (26) from falling into the space (25) between the floor plates during installation, and the floor plates (24) (24). If the device is not lifted up in an unstable state, the mutual expansion and contraction displacement cannot be absorbed smoothly.

状の遊空間を形成することに特徴がある。EFFECT OF THE INVENTION The joint in the road bridge joint portion of the present invention has the structure described above, and the upper end sides of the pair of joint members are brought into contact with each other and abutted against each other, and the lower end sides thereof are inclined so as to spread apart. Thus, the space between the joint members on the road surface is made as small as possible, and a wide hem-shaped play space having a large opening is formed at the underground seating portion of the road joint.

る。Since the joints thus installed at the joints of the road bridge have a very small gap on the surface of the joints to form a play gap, the joints at the joints of the road bridges on the tire surface when the vehicle is running. By eliminating the noise generated by the space, it is possible to reduce local pollution due to running noise in this amount as much as possible. You can get a comfortable ride without feeling the seams.

の安全性を高めるのに役立つ。Further, due to the small contact state of the crossover space on the surface of the seam, the inflow of rainwater is prevented to a minimum, and the receiving member in the free space with a wide skirt spreads in the pocket smoothly leads to the side groove. Therefore, it is possible to prevent the accumulation of rainwater on the surface of the seam of the road bridge, which helps to improve the safety when driving the vehicle in the rain.

奏する。Moreover, the lower end side of the joint member serves as a barrier that greatly separates from the space between the floor plates of the road bridge joint,
In order to prevent the curing concrete when installing the joint from flowing down the play space to the floor board play, it is easy to install the joint to the road bridge joint part and improve the efficiency of the installation work, as well as the bridge girder and the support that supports the floor board. The concrete does not fall down to the metal part of the part during installation and the free space with enough allowance allows a receiving member with a large expansion / contraction rate to be installed, so even a large expansion / contraction displacement can be received. Can be fully absorbed. Therefore, the durability of the road bridge is further increased without corroding the main portion of the road bridge support made of steel quickly due to the reaction with the cement component due to water leakage.
