本考案は、道路継目部においてジヨイント部材

を破損するという問題がある。 At road joints, we used joints in which steel toothed plates were interlocked with some play and concrete was cast behind them, and rubber plates were bridged over the gaps in the joints and buried in the concrete. Various types of joints, such as joints fixed to anchor bars, have been constructed, but usually the concrete part on the back is more susceptible to being hit by vehicles than joints made of steel or rubber. It wears out quickly and creates a step between the joint member and the concrete part. Therefore, this difference in level deteriorates the running performance of the vehicle, and the impact when the vehicle passes over the difference in level can cause cracks in the concrete, early damage to the joint members, and even noise.
There were problems with vibrations and other road pollution. In addition, in road bridges built in snowy areas, vehicles often have chains attached to their wheels or use spiked tires, and the number of times snowplows drive is increased. There is a problem in that the chains and spiked tires increase the impact when a vehicle passes by, and the scraper of the snowplow collides with the joint member, damaging the joint member.

ある。 On the other hand, as disclosed in Japanese Utility Model Application Publication No. 56-33303, there has been a proposal to provide a flat plate, that is, a horizontal protection member, in the concrete portion of the road joint. However, in the case of this proposal, it is necessary to attach an anchor to the protective member in order to prevent it from peeling off during use, and the protective member is slightly bent by the wheel load of the vehicle, resulting in poor running performance. It is a shame that it not only causes damage, but also is not very durable.
本考案は、かかる点に鑑み、道路継目部におい
てジヨイント部材およびコンクリート部を保護す

ことを特徴とする。 In view of this point, the present invention provides a protection reinforcing member with a simple structure that can protect joint members and concrete parts at road joints, and eliminates the above-mentioned conventional problems. That is, the protection reinforcement member according to the present invention is a vertical plate-like body with a substantially vertical plate surface, and a horizontal part that matches the height of the road surface is formed at the front of the upper end. Next, a sloped part is formed at the rear of the upper end that slopes downward to the rear, and the front end of the horizontal part faces the back of the joint member and comes into contact with the through line extending in the longitudinal direction of the road joint. It is characterized in that it is connected together and placed in the concrete part of the road joint.
すなわち、この保護強化部材の作用は次のとお
りである。 That is, the action of this protection reinforcing member is as follows.
車輛のタイヤを水平部からジヨイント部材の
上に移行せしめ、このジヨイント部材の背部コ
ンクリート部の轍ぼりを少なくする。 To move a vehicle tire from a horizontal part onto a joint member and reduce rutting on the concrete back part of the joint member.

ヨイント部材に対し衝撃を与えることを防止す
る。 Even if the concrete portion is worn out, the scraper of the tire or snowplow moves from the inclined portion to the horizontal portion to the joint member, thereby preventing impact from being applied to the vehicle or the joint member.

強化部材を道路継目部に構築することが容易と
なる。 Road joints are provided with a large number of intersecting reinforcing bars, such as distribution bars in the bridge axis direction, stirrup bars in the vertical direction, and main bars in the longitudinal direction of the joint, and it is difficult to provide a plate-like member separate from these reinforcing bars due to space considerations. Although it is very difficult to do so, the protective reinforcing member is placed in contact with and connected to the through-bar, so while the through-bar is connected to the existing reinforcing bar, the protective reinforcing member is placed on top of the through-bar. This makes it easy to construct protective reinforcing members at road joints without causing interference with existing reinforcing bars.

じない。 In the above-mentioned joint 7, since the horizontal part 4 of the protection reinforcing member 1 is aligned with the road surface 9, the tires of the vehicle often pass over the horizontal part 4, and the post-cast concrete part 8 is used for each protection reinforcement. Part 1
There is almost no wear on the parts located between the horizontal parts 4. Therefore, the occurrence of a level difference at the boundary between the joint member 10 and the post-cast concrete part 8 is prevented, and the horizontal part 4 is at the same height as the joint member 10, so that a good vehicle can be achieved. Runnability can be maintained for a long period of time. In particular, in this embodiment, since the interval between the protection reinforcing members 1 is narrower than the tire width, the tire always passes over the horizontal part 4 of the protection reinforcing member 1, and the joint member 10 and the post-cast concrete part 8 are connected to each other. Rutting of the post-cast concrete part 8 at the boundary part hardly occurs.
