本考案は道路のジヨイント部材に関し、道路継
目伸縮装置に利用するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a road joint member, and is used in a road joint expansion/contraction device.

噛合形式の伸縮装置を構成するものである。(Prior Art) An example of a road joint expansion/contraction device is a so-called finger joint. The joint member of this telescoping device is made by welding a finger-shaped steel face plate to a support member consisting of a vertical plate (web) and a bottom plate, and by meshing the pair of face plates with each other,
This constitutes an interlocking type expansion and contraction device.

ならざるを得ないという問題も有している。 However, since the above-mentioned joint members are fixed directly to the steel girder, it is difficult to use a retrofitting method, that is, a method of attaching the joint members after the slab is cast. There is a problem that the top surface of the face plate is tilted when the levelness is low. Furthermore, since the face plate is widely exposed on the road surface, concrete is not sufficiently filled under the face plate when concrete is placed on the floor slab, resulting in insufficient concrete placement and a problem of lower load-bearing strength. In addition, when a wheel load is applied to the finger-shaped protrusion of the face plate, the protrusion may break, and furthermore, it takes a lot of time and effort to form the finger-shaped protrusion. It also has the problem of being expensive.
（考案の目的）
本考案は、かかる点に鑑み、上記噛合形式の道

作できるようにすることにある。 In addition, other purposes of the present invention are to prevent insufficient filling and pouring of concrete during concrete construction in an interlocking type expansion and contraction device, to protect and strengthen post-cast concrete, and to prevent joint members from forming during construction. To make it possible to align the upper surface with the road surface, to increase the load-bearing strength of the protruding part toward the clearance side, to prevent breakage due to wheel loads, and to make the joint member itself inexpensive to manufacture. It's about doing.

It is supported by a vertical plate. Even when the vertical plate of the road surface member is fixed at an angle, the horizontal part can be kept level and the locking part can be locked to the vertical plate.
Due to this locking, the wheel load applied to the protruding portion is transmitted to the vertical plate via the locking portion.

部材１と後打コンクリート１８との境界に若干の
段差が生じても、その境界線が波形であるため車
両走行性を大きく阻害することがない。 In the above-mentioned joint 13, the road surface portion 6 of the road surface member 5 is flush with the road surface, a corrugated joint clearance 10 is formed by the pair of joint members 1, 1, and a joint gap 10 between the joint member 1 and the post-cast concrete 18 is formed. The border line is also wavy (comb-shaped). Therefore, the vehicle has a lower protrusion 7 protruding from one vertical plate 2 than a protrusion 7 protruding from the other vertical plate 2.
Since the tires are always in contact with the ground when traveling across road joints, the vehicle's driving performance is good. Further, even if the post-cast concrete 18 is worn out and a slight step is formed at the boundary between the joint member 1 and the post-cast concrete 18, since the boundary line is wave-shaped, the running performance of the vehicle will not be significantly impaired.
縦板２の各切込部３の間隔Ｓ、つまり、各路面
部材５の間隔は、後打コンクリート１８の摩耗防
止を図るうえで車両のタイヤ巾よりも狭く（例え
ば、100mm程度）するのが好ましい。 In order to prevent wear of the post-cast concrete 18, the interval S between each notch 3 of the vertical plate 2, that is, the interval between each road surface member 5, is preferably narrower than the vehicle tire width (for example, about 100 mm). preferable.
しかして、車両通過時、路面部材５は突出部７

止される。 Therefore, when the vehicle passes, the road surface member 5
However, since the locking portion 9 is in contact with the vertical plate 2, the wheel load is transmitted to the vertical plate 2 via the locking portion 9. That is, since the protrusion 7 is not in a cantilevered state, breakage due to wheel loads is prevented.

足を生じることがない。 Further, during construction, the vertical plate 2 of the joint member 1 functions as a template when pouring concrete 18, and each road surface member 5 is provided at intervals in the road width direction, Because the surface is not widely covered, concrete road surface members 5
The concrete flows well to the lower side, and there is no possibility of insufficient concrete placement.

この係止部９を縦板２に当接することができる。
従つて、上述の如く、突出部７にかかる輪荷重を

面部６を道路表面に合わすことができる。 Therefore, when assembling the vertical plate 2 to the road joint, the vertical plate 2 is not vertical when the anchor bar 4 and other reinforcing bars are connected, and is slightly tilted forward toward the clearance side as shown in Fig. 4. However, even in such a case, when the road surface member 5 is held horizontally and fitted into the notch 3, the locking part 9 protrudes toward the vertical plate 2, so
This locking portion 9 can be brought into contact with the vertical plate 2.
Therefore, as described above, it is possible to transmit the wheel load applied to the protrusion 7 to the vertical plate 2. In short, in the case of this example, the inclination angle α of the surface of the extension portion 8 facing the vertical plate 2 is within a range that allows the inclination of the vertical plate 2, and after allowing the inclination of the vertical plate 2, the road surface member 5 The road surface portion 6 can be aligned with the road surface.

A locking portion 44 is provided. In the case of this example, when a wheel load acts on the protrusion 42, the road surface plate 40 receives a force in a clockwise direction using the bottom of the notch in the vertical plate as a fulcrum in the illustrated example, but since the extension part 43 is long, , the resistance force against the force in the clockwise direction is large, and the stability of the road surface member 40 is increased.

を縦板に係止せしめることができる。(Effects of the invention) According to the invention, it is possible to obtain a joint that has a wave-shaped joint clearance and has a wave-shaped boundary between the joint member and the concrete and has good vehicle running properties. Since it is fixed to the vertical plate at least, the load-bearing strength of the protruding part is increased, and even if the vertical plate is installed in an inclined state, the locking part can be attached to the vertical plate with the road surface part of the road surface member horizontal. It can be locked.
