【産業上の利用分野】本発明は、モルタルの浮きを補修
する工事においてモルタルの浮きを確認する方法に関し
ている。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for confirming mortar floating in a work for repairing mortar floating.

いる。2. Description of the Related Art When a gap between a mortar serving as a finishing layer of a concrete building and a concrete skeleton, that is, so-called floating of the mortar occurs, a hole from the mortar to the concrete skeleton is formed, and an epoxy resin is filled in the hole. Repair work has been performed in which an anchor pin is inserted at the same time as injection or resin is injected to integrate the mortar and the skeleton.

害してしまうことになる。In this repair work, it is important to accurately know the thickness of the mortar, the position of the float, the size of the float, and the presence or absence of other defects. Chips generated during the drilling operation are removed from the holes before the resin is injected. However, if the chips are not completely removed, clogging of the floating gap may occur. Flow will be obstructed.
【０００４】コンクリート躯体の表面をモルタルで仕上

り、モルタルの厚みが場所によって異なるのが一般的で
ある。このため、補修のためにあけられた穴内を観察し

補修ができないことになる。[0004] One of the purposes of finishing the surface of the concrete skeleton with mortar is to obtain smoothness of the finished surface, and the thickness of the mortar generally varies depending on the location. For this reason, the desired repair cannot be performed unless the inside of the hole drilled for repair is checked to confirm the thickness and floating state of the mortar.

望まれる所以である。In the prior art, a method of checking the inside of a hole includes a method of inserting an earpick-shaped metal rod into a drilled hole and making a judgment based on a feeling when the tip of the metal rod is caught on a floating portion when moved. A method of observing using an endoscope is known. However, the former of the prior art has a problem that it is not always possible to judge the state of the hole accurately because there are many parts that depend on the intuition of the operator, and the latter cannot grasp the entire situation because only the local part is captured. There is a point, and this is the reason why a method capable of confirming holes more accurately and easily is desired.

するものである。A first means for solving the problems in the present invention is to inject a liquid resin together with a viscous liquid resin or a rod into a hole formed in a concrete skeleton through a mortar, The method is characterized in that the liquid resin is cured into a rubber state and then pulled out and the inside of the hole is modeled. The second means is to insert a tubular paper into the hole formed in the concrete body through mortar. It is characterized in that the paper is inserted and the inside of the hole is copied by rubbing or pressing the paper.

よい。FIG. 2 shows a first method of observing a hole, in which the state of the hole is molded using a resin. A liquid resin 10 is injected into the perforated hole 3 and cured into a rubber shape, and then pulled out to observe the state of the hole. The resin to be injected is preferably a two-pack type silicone or the like, which does not adhere very much to the contact portion and has a rubber-like property that can be easily pulled out. After curing, it is preferable to insert the metal rod 11 at the same time as injecting the resin so that the resin can be easily pulled out.
