三角形状の段差解消パツトを提案した。(Prior art) The present applicant has filed Utility Application No. 59-105152 (U.S. Pat.
(see Publication No. 23302), it has an inclined surface extending from a high road surface to a low road surface, and is removably disposed on the low road surface in contact with a step that occurs between the high road surface and the low road surface, and is attached along the length direction of the step. We proposed a step-removal part with an elongated triangular cross section.

（考案が解決しようとする問題点） しかし、上記した段差解消パツトでは段差解消
のための仮舗装作業を不要とし、道路改装作業の
能率化を図ることができたが、段差の大きさが異

解消パツトを用意しなければならない。(Problem that the invention aims to solve) However, although the above-mentioned level difference elimination part eliminates the need for temporary paving work to eliminate the level difference and improves the efficiency of road renovation work, the size of the level difference is different. In such cases, it is necessary to prepare various level difference eliminating parts depending on the size of the level difference.

即ち、道路の改装工事は上下線の片側車線ずつ
行なわれ、片側車線のアスフアルトやコンクリー
トの舗装部分を剥して改装工事を行なう。 In other words, road renovation work is carried out on both the up and down lanes, and the asphalt or concrete paved portions of each lane are removed and the renovation work is carried out.

このため、舗装部分を剥された部分は低路面と
なり、他方の車線の舗装部分の上面との間に段差
が生じる。 For this reason, the part where the paved part has been removed becomes a low road surface, and a level difference occurs between the part and the top surface of the paved part of the other lane.

この段差の大きさは舗装部分の肉厚により決定
されるが、舗装部分の肉厚としては一般的に二種
類のものがある。例えば、舗装部分の肉厚の厚い
ものでは約50mm、薄いものでは約30mmとなつてい
る。 The size of this step is determined by the thickness of the paved portion, and there are generally two types of thickness of the paved portion. For example, the thickness of the paved portion is approximately 50 mm for thicker sections, and approximately 30 mm for thinner sections.

しなければならなかつた。 Therefore, with the above-mentioned conventional products, two types of parts are manufactured according to the height of the upper end of the slope depending on the thickness of the paved part, thick and thin, and two types of parts are transported to the construction site. Therefore, two types of parts had to be used selectively depending on the thickness of the paved part.

このため、少なくとも二種類のパツトを製造し
なければならないので、パツトの価額が高価とな
つてしまい、また、パツトの運搬に手数が掛ると
共に、保管場所に広いスペースを必要としてい

込めるようにしたものである。 On the other hand, the reason why each part 2, 4 has more rivet holes 13 for nails than the number required to fix each part 2, 4 to the low road surface a is to prevent damage to the tack holes 13. This is what I did. This is because, if only the number of rivet holes 13 required to fix each part 2, 4 to the road surface are opened, each part 2, 4 must be removed from the low road surface a each time construction begins. Since the nails 18 are fixed to the low road surface a every time construction is completed, the nails 18 are driven into the same rivet holes 13, and the rivet holes 13 expand in diameter with repeated use, and the nails 18 are held securely. I won't be able to do that. Furthermore, there is a risk that the stud holes 13 may be damaged due to intense vibrations caused by vehicles passing over the parts 2, 4, and the nails 18 may come out, causing the parts 2, 4 to be scattered on the road surface. Therefore, in the embodiment, a large number of rivet holes 13 are opened in each part 2 and 4, so that when construction is restarted, an unused rivet hole 13 can be selected and a nail 18 can be driven into it.

尚、前記したスリツプ防止用溝１６は、各パツ
