ある。[Detailed description of the invention] The present invention relates to a manhole foothold device that is extremely durable, safe, waterproof, and workable. A stainless steel step with screws drilled at the ends of the insertion parts on both sides and a sleeve at the base thereof, and an insertion hole through which the pair of insertion parts of the step can be respectively inserted, and a stainless steel step on the outside of the insertion hole. This invention relates to a foothold device for a manhole, which is constructed from a combination of a concrete cylinder having a recess around it and a sealing material that can be attached around the insertion part of a step.

テップを取付けた部分が漏水する等の欠点があった。Conventionally, manhole steps commonly used were made of steel or made of steel coated with polypropylene, etc., but the former was corroded by water droplets and hydrogen sulfide generated inside the manhole. It doesn't last long,
In addition, the latter has disadvantages such as the possibility that the plastic deteriorates due to long-term use and that dirt enters the coating layer and causes corrosion of the core material, and it is difficult to attach it to a concrete cylinder in a stable manner. However, there were disadvantages such as poor workability and water leakage from the part where the step was attached.
本考案に係る装置は従来の之等の欠点に鑑み全く新規に
開発された技術に関するものである。The device according to the present invention is a completely new technology developed in view of the drawbacks of the prior art.

ストッパー５が設けられている。To specifically explain one embodiment of the present invention with reference to the drawings, the first embodiment is as follows.
In the figure, 1 is a wide step made of stainless steel used in the device of the present invention, and the upper surface of its main body is entirely provided with unevenness 2 that intersects in the axial direction. The insertion part 3 is a small-diameter round rod-shaped insertion part 3. A screw 4 is bored at the tip of the insertion part 3, and stoppers 5 are provided on both sides of the base of the insertion part 3.

設されている。Next, in FIGS. 2 and 3, reference numeral 6 denotes a concrete pipe used in this device, and on its peripheral wall are the steps 1 and 2.
A pair of insertion holes 7 are bored through which the insertion portion 3 can be inserted, and recesses 8 and 9 are formed around the entrance portions of the insertion holes 7, respectively.

されたモルタルである。Further, 10 is a sealing material such as a rubber gasket wrapped around the base and tip of the insertion part 3 of step 1, 11 is a nut screwed onto the screw 4 of the insertion part 3, and 12 is a sealing material buried in the recess 9. It is made of mortar.
上記シール材１０を安定した状態で挿通部３に取付ける
場合には第４図に示す如く、凹所９内の挿通孔７の周り

能である。When attaching the sealing material 10 to the insertion portion 3 in a stable state, it is also possible to form a mounting recess 13 for the sealing material 10 in advance around the insertion hole 7 in the recess 9, as shown in FIG. be.

徴を有するものである。As mentioned above, in the device of the present invention, the steps are made of stainless steel, so there is no risk of corrosion from water droplets in the manhole or hydrogen sulfide, and the main body is wide, so there is no need for footrests. It can be installed in a linear arrangement without alternating positions, and since the entire top surface of the main body is provided with depressions and depressions that intersect in the axial direction, water does not accumulate in the depressions. There is no risk of your feet slipping, and there is a stopper at the base of the insertion part of the step, which allows you to fix the step to the concrete cylinder at the correct depth, and Since the seal material is wrapped around the step, it is possible to prevent water leakage from the step mounting part.
Furthermore, since a recess is provided at the entrance of the insertion hole of the concrete pipe, by filling this part with mortar, the threaded part of the step and the nut can be completely buried in the wall of the pipe, giving it an aesthetically pleasing appearance. It has features such as being able to prevent the nuts and sealing material from loosening or corroding and deteriorating, and to further improve the waterproofness of the mounting portion of the step.
