【考案の詳細な説明】 （考案の技術分野） 本考案は、マンホールの首部上に配されるマンホール用
蓋枠を所定位置に位置決めするために用いる治具に関す
る。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a jig used for positioning a manhole cover frame arranged on a neck portion of a manhole at a predetermined position.
（考案の技術的背景） マンホール上の路面（又は地面）位置は路面補修工事や
地盤沈下等により変化することがある。(Technical background of the device) The position of the road surface (or ground surface) on the manhole may change due to road surface repair work or ground subsidence.
そして、路面位置が変化すると、マンホール用蓋と路面

め、通常はマンホール用蓋を路面に一致させる修復工事
が行なわれている。When the road surface position changes, a step is generated between the manhole cover and the road surface, which makes it impossible for a vehicle to pass through or makes it difficult for a pedestrian to walk. For this reason, repair work is usually performed to match the manhole cover to the road surface.
さて、この修復工事では、マンホールの首部周囲を掘削

し、この測定寸法とマンホール用蓋枠の高さ寸法との差
分だけ首部上にブロック等を積み上げ、その上にマンホ
ール用蓋枠を位置決め、固定している。By the way, in this repair work, the manhole neck was excavated, the manhole cover frame placed on the neck and the manhole cover for closing the cover frame were removed, and then the excavation position was tacked. Tension the water thread according to the position of the road surface, measure the distance between the water thread (road surface) and the upper end surface of the neck, and place a block or the like on the neck by the difference between this measurement and the height of the manhole cover Stacked, the manhole cover frame is positioned and fixed on it.
（背景技術の課題） しかし、このように丁張りをかけて水糸を張るためには

業を繰り返さざるを得なかった。(Problems of the background art) However, in order to stretch the string with the tension as described above, a skilled person is required for the work, and even a skilled person requires a great deal of labor and time for the work. Will end up. Further, as described above, since the measurement work or the like using the water thread as a reference must be performed, a measurement error or a measurement error is likely to occur. For this reason, the upper end of the mandrel cover frame may not be aligned with the road surface after the manhole cover frame is positioned, and in this case, the same work had to be repeated.
（考案の目的） 本考案の目的は、マンホール用蓋枠を作業性よく、しか

に設けられている。In these drawings, reference numeral 1 denotes a base plate, which is made of an acrylic plate and has a donut shape having a circular hole in the center. The base plate 1 has a wall thickness of 5 mm, and is formed to have the same outer diameter (for example, 1280 mm) or slightly larger than the outer diameter of the neck portion 4 (see FIG. 4) of the manhole. A pair of lid frame height indicating members 2 stand up from the base plate 1. These display members 2 are formed of a rectangular acrylic plate, and are fixed to the base plate 1 so as to intersect at right angles. Display lines 2a and 2b are provided above each lid frame height display member 2 along the longitudinal direction. These display lines 2a or 2b and the base plate 1
The distance h from the lower surface of the manhole cover indicates the height dimension h'from the lower surface of the flange 10a to the upper end of the two types of manhole cover frames 10 (see FIG. 5). That is, the display line 2a or 2b is the lid frame height display member 2 so that the relationship of h = h 'is established.
It is provided in.
次に、本考案の位置決め治具の使用態様を説明する。Next, a usage mode of the positioning jig of the present invention will be described.
先ず、第３図（Ａ）、（Ｂ）に示す高さ調整具５を用意

周面に等間隔で溶接されている複数の筒体７と、これら
の筒体７に上下よりそれぞれ螺入されているねじ棒８
ａ、８ｂとから成る。First, the height adjuster 5 shown in FIGS. 3A and 3B is prepared. The height adjuster 5 has a circular ring 6, a plurality of cylinders 7 welded to the outer peripheral surface of the ring 6 at equal intervals, and screw rods screwed into the cylinders 7 from above and below, respectively. 8
a and 8b.
次に、この高さ調整具５を、第４図に示すように、マン
ホール３の首部４上端面に載置する。Next, the height adjuster 5 is placed on the upper end surface of the neck portion 4 of the manhole 3, as shown in FIG.
次いで、高さ調整具５のねじ棒８ａ上に本考案の位置決

ランジ１０ａ下面位置と一致する。Next, the positioning jig of the present invention is placed on the screw rod 8a of the height adjuster 5. Then, the protrusion amount of the screw rod 8a is adjusted so that the display line 2a (or 2b) of the lid frame height display member 2 matches the height of the road surface 9. Therefore, the upper end position of each screw rod 8a coincides with the lower surface position of the flange 10a when the manhole cover frame 10 is arranged at various positions.

高さ調整具５は該ブロック部１２に埋設されて補強材と
して機能する。After that, the positioning jig of the present invention is removed, the molds 11 and 11 composed of veneer plates and the like are assembled on the inner wall of the neck portion 4 and the outside thereof, and concrete is poured between these molds 11 and 11. In this case, the height of the concrete is screw rod 8a.
As a result, the concrete block portion 12 lower than the road surface 9 by the height dimension of h'is formed on the neck portion 4 as shown in FIG. still,
The height adjusting tool 5 is embedded in the block portion 12 and functions as a reinforcing material.

なる。Finally, as shown in FIG. 5, the lower portion of the manhole cover frame 10 is inserted into the concrete block portion 12 and the flange 10 a is locked onto the block portion 12. Therefore, since the height dimension of h'exists between the upper surface of the concrete block portion 12 and the road surface 9, the upper end of the manhole cover frame 10 coincides with the road surface 9. Therefore, when the upper opening of the manhole cover frame 10 is closed by the manhole cover 13, the upper surface of the cover 13 and the road surface 9 coincide with each other.

By matching b) to the road surface 9, the manhole cover frame 10
Concrete block part 12 at a position lower by the height dimension of
Can be placed. Therefore, the manhole cover frame 1
It is possible for 0 to be arranged in conformity to the road surface easily and with good workability even by an unskilled person.
