【考案の詳細な説明】
本考案は、コンクリート、石等の構築物に生じたクラツ
クに補修液を充填して補修する際の補修液注入口を形或
するための型材に関するものである。[Detailed Description of the Invention] The present invention relates to a mold material for forming a repair fluid inlet when repairing a crack in a structure such as concrete or stone by filling it with a repair fluid.
一般に、クラツク内に補修液を充填する場合は、クラツ
クと交差して粘着テープを貼着し、クラツク上を適宜の
シール剤でシールした後、上記テープを剥離して注入口
を形或し、先端にゴム製の当口を突設した補修液充填ノ
ズルをこの注入口に圧接して補修液をクラツク内に充填
する工法が盛用されている。Generally, when filling a repair liquid into a crack, adhesive tape is pasted across the crack, the crack is sealed with an appropriate sealant, and then the tape is peeled off to form an injection port. A commonly used method is to press a repair fluid filling nozzle with a rubber opening at its tip into pressure contact with the injection port to fill the crack with repair fluid.
この工法においては、幅の狭いクラツク上に細いノズル
の先端を圧接しなければならないのであるが、圧接時に
クラツクとノズルの液流口とが一致しているかどうかを
目で確認することができず、作業者の勘の働らかせどこ
ろであった。In this method, the tip of a thin nozzle must be pressed onto a narrow crack, but it is not possible to visually confirm whether the crack and the liquid flow opening of the nozzle are aligned during pressure contact. , it was a matter of the worker's intuition.
従って、往々にして液流口がクラツクとずれてしまい、
この状態で補修液の圧入を開始すると、液圧だけが上昇
してノズルと当口との間或いは当口とコンクリート面と
の間から補修液が漏洩した補修液がクラツクの入口部分
に付着して硬化し、不完全な補修結果を招来していた。Therefore, the liquid flow port often becomes misaligned, and
If you start press-fitting the repair liquid in this state, only the liquid pressure will rise, and the repair liquid that leaked from between the nozzle and the opening or between the opening and the concrete surface will adhere to the entrance of the crack and harden. However, this resulted in incomplete repair results.
本考案は、従来工法におけるこれらの欠点を是正するた

一に形戊すると共に型材１の外周縁部に型材１の中心線
ｌ上で対向する２つの切り欠き部２，３を形威して注入
口形戒用型材としたものである。In order to correct these shortcomings in the conventional construction method, the present invention provides a mold material for forming an injection port such that the liquid flow port of the nozzle is reliably located above the crack when filling the repair liquid. As shown in the drawings, the outer shape of the mold 1 is shaped to be approximately the same as the shape of the elastic abutment 14 provided at the tip of the nozzle 12, and the outer periphery of the mold 1 is provided with a The two opposing notches 2 and 3 are shaped to form an inlet-shaped precept material.
この型材１を用いて補修液の注入口を形或する場合は、
まず、第３図に示したように、クラツク１０上に適宜の
間隔で（クラツクの深さと同じ間隔を置くのが通例であ
る。When forming the injection port for the repair liquid using this mold material 1,
First, as shown in FIG. 3, it is customary to place the cracks at appropriate intervals on the crack 10 (at intervals equal to the depth of the crack).
）型材１を仮接着する。このとき、相対向する切り欠き

ため、クラツク１０は型材１の中心を通ることになる。) Temporarily glue the mold material 1. At this time, if the notches 2 and 3 facing each other are positioned on the crack 10, the notches 2 and 3 are facing each other on the center line l of the molded material 1, so the crack 10 is placed on the crack 10. It will pass through the center of
クラツク１０上に型材１，１を配置した後、露出してい

剤でシール１１を形威し、シール１１が硬化した時点で
この型材１，１を剥すと、クラック１０が中心部を通る
状態で、型材１と略同形の注入口が形或される。After placing the molding materials 1, 1 on the crack 10, a seal 11 is formed on the exposed crack 10 with a sealant made of resin or inorganic material, and when the sealing material 11 is hardened, the molding material 1, When the mold material 1 is peeled off, an injection port having substantially the same shape as the mold material 1 is formed with the crack 10 passing through the center.
次に、図示しない補修液充填機に連結したノズル１２の
先端に設けた弾性当口１４を注入口に圧接するのである

当口１４は注入口で位置決めされ、その中心を容易に注
入口の中心即ちクラツク１０上に位置させることが可能
となる。Next, the elastic abutment 14 provided at the tip of the nozzle 12 connected to a repair liquid filling machine (not shown) is pressed into contact with the injection port, and the injection port is formed of a profile 1 having approximately the same shape as the elastic abutment 14. For this purpose, as shown in FIGS. 4 and 5, the resilient abutment 14 is positioned at the inlet and its center can be easily positioned over the center of the inlet, ie, over the crack 10.
しかも、シール剤の塗りむらやシール剤の硬化時の収縮
更には型材１を剥す際に生ずる若干のシール１１の剥れ

１４とシール１１との間でクラツク１０が露出すること
はない。Moreover, uneven coating of the sealant, shrinkage of the sealant when it hardens, and slight peeling of the seal 11 that occurs when the mold material 1 is peeled off occur, causing the elastic abutment 14 and the seal 11 to peel off, as shown in FIG. Although there is a slight gap 16 between the mold material 1 and
Since the seal 11 is in a protruding state on the crack 10 corresponding to the notches 2 and 3, the crack 10 is not exposed between the elastic abutment 14 and the seal 11.
そこで補修液充填機を操作して補修液の注入を開始する
と、補修液はノズルの液流口１３及びこれと連通ずる弾
性当口の貫通孔１５を通ってクラツク１０内にスムース
に注入されているのである。When the repair liquid filling machine is operated to start injecting the repair liquid, the repair liquid is smoothly injected into the crack 10 through the liquid flow port 13 of the nozzle and the through hole 15 of the elastic abutment that communicates with the liquid flow port 13. It is.

と共にノズルを圧接した際にクラツクを完全にシールす
ることができる。As described above, by using the profile according to the present invention, it is possible to form an injection port that can reliably position the elastic through-hole provided at the tip of the nozzle on the crack, and also to press the nozzle into contact. Cracks can be completely sealed.
従って、補修液は確実にクラツク内へ注入され、クラツ
クの入口に滞留硬化して不完全な注入を心配する必要は
ない。Therefore, the repair liquid is reliably injected into the crack, and there is no need to worry about incomplete injection due to retention of the solution at the entrance of the crack and hardening.

日は円形のものが一般的であるために円形の型材を示し
たが、これは弾性当日の形状に合せた他の形状であって
も良い（第６図参照）。In the above example, a circular shape is shown because the shape of the elastic material provided at the tip of the nozzle is generally circular. Good (see Figure 6).
また、切り欠き部は、クラツク上にシールが突出した状
態を形戊するためのもので、その形状は問わない。Further, the notch is used to form a state in which the seal protrudes above the crack, and its shape is not limited.
更に、切り欠き部は、上記の実施例においては相対向す

き部を形威しても良い。Furthermore, although the above embodiment shows two notches facing each other, as shown in FIG.
It is also possible to form cutout portions that face each other on a plurality of center lines lZIII.
この場合は、一つの切り欠き部がシール剤等で目一りを
起しても切り欠き部を使用できる利点がある。In this case, there is an advantage that one notch can be used even if one of the notches is damaged by a sealant or the like.

２２を穿設して型材としても良い。In each of the above embodiments, the face plate is used as the shape material, but as shown in FIG. 8, the frame 21 may be used as the shape material, and as shown in FIG. 9, the center of the face plate A hole 22 may be bored in the section to form a mold material.
この場合には、型材をクラツク上に仮接着する際に、型
材内でクラツクを視認することができる。In this case, the crack can be visually recognized within the mold material when temporarily bonding the mold material onto the crack.
