Field of the Invention The present invention relates to an apparatus and a method for repairing a concrete crack for filling or infiltrating a repair filler for cracks generated in a concrete frame, for example, a building structure or a concrete column.

Description of the Related Art Conventionally, for cracks such as cracks generated on the surface of a concrete structure, a filler such as an epoxy resin is injected from above the cracks into the crack space by applying pressure with an injector. Was common. However, the method of applying pressure to the injector has drawbacks in that the operation of fixing and removing the injection seat becomes complicated, or that it is difficult to feed the filler into a narrow crack space.

As shown in FIG. 4, this conventional repairing device includes a suction part 101 provided on the inside and a filler supply part 104 provided on the outside, and sucks air in a crack space inside the crack 106 while reducing the pressure. , Filler supply unit 10 arranged in contact with cracks
In this configuration, the filler was sucked from No. 4 and injected into the crack space.

It was impossible. In addition, since the filler is moved from the other side of the body, the material is limited to a material having a high fluidity, thereby causing a problem such as outflow of the filler. Further, in the conventional repair device, the suction seat 102 constituting the suction part 101 was small, so that a closing operation such as attaching a temporary fixing seal to a portion other than the suction seat 102 was necessary. In addition, in the filler supply section 104, it is necessary to apply a filler that covers the entire crack.
Furthermore, since the filler is drawn in by the flow of air by suction, it flows in the shortest direction, and it is difficult to spread the filler over the entire crack. In addition, construction was not possible if there was only one working space.

けるのが望ましい。It is desirable that the box has a shape that covers the entire crack. In this case, there is no need for preparation work such as tape application.
In addition, the crack opening part of the part which cannot be covered with a box is covered with a shielding material such as a seal, so that the crack is closed. The box body is open on one side, and the box body is sealed with an elastic material or the like attached around the box body. It is desirable to provide a window made of a transparent body on the front surface so that the movement of the nozzle inside the box and the application state of the filler can be grasped.

A material that expands after being filled is desirable. Thereafter, the air pump is operated to bring the inside of the box to normal pressure or pressurized state, and the applied filler is caused to enter the crack space by utilizing the pressure difference generated by the operation. That is, since the crack space has a negative pressure close to a vacuum, a strong drawing force acts, and at the same time, a pushing force acts from the outside.

Surface peeling after repair is less likely to occur. In order to cope with extremely narrow cracks and deep cracks, it is desirable to generate a high pressure reduction state in the crack space with a powerful air pump.

The crack repairing device 1 shown in FIG. 1 is mounted on one surface side opening 16 a of a crack 16 generated in the concrete skeleton 15, and the other surface side opening 16 c is sealed with a shielding material 7. When there is no work space for installing the shielding member 7, that is, in the case of a concrete column 25 as shown in FIG. 3, a quick-drying resin for the shielding layer is formed on the inner wall surface 25b by using the ventilation hole 25a communicating therewith. Spray 17 For this spraying operation, a shielding material application nozzle 8 that can move inside and a camera 9 with illumination for confirming the operation are required, and these are inserted through the ventilation holes 25.

させ躯体と一体化することができる。The crack repairing device 1 sucks from the opening side particularly in the case of a closed crack, so that it can be filled without being limited to a filler made of a material having high fluidity, and the outflow of the filler is also possible. Less. Further, since the box 2 covers the cracks in a certain range, the closing work such as attaching a temporary fixing seal is reduced, the preparation work for filling is simplified, and the repair work in a short time becomes possible. Further, since suction is performed evenly in the box 2, the filler can be evenly spread over the entire crack. Therefore, even if the concrete surface is ragged due to aging, the filler can entirely penetrate and be integrated with the skeleton.
