FIG. 1 is a perspective view of the hole filling device according to Embodiment 1, and FIG. 2 is a side view of the hole filling device. As shown in FIGS. 1 and 2, the hole filling tool 1 includes a disk-shaped head 10 and a shaft-shaped main body 11. One surface of the head 10 is connected to one end of the main body 11. The other surface of the head 10 is provided with two small holes 13 arranged in the radial direction. The small holes 13, 13 are located symmetrically with respect to the center of the head 10. On the other surface of the head 10, a pattern is formed in accordance with the wall surface of a wall used in a method described later. In addition, a mode in which no pattern is formed on the head 10 may be employed. Alternatively, a member made of brick or another material may be attached to the other surface of the head 10.

  The other end of the main body 11 has a tapered shape that becomes thinner toward the front end. The main body 11 is provided with a split groove 110 from the other end to the center. On the outer peripheral surface of the main body 11, a male screw 12 is provided at a portion corresponding to the split groove 110. The hole filling tool 1 is formed of a flexible material or the like, and the main body 11 can be deformed so that the width of the split groove 110 is reduced. Thereby, the main body 11 can be deformed so as to reduce the outer diameter. As a material for the hole filling device 1, for example, a resin such as ABS (Acrylonitrile butadiene styrene), polyvinyl chloride or polypropylene, or rubber is used. By forming the head 10 with the use of ABS or polyvinyl chloride, the head 10 can be satisfactorily coated as described below.

Here, in work such as repainting of a building such as an apartment or a building or repairing of an outer wall, a grip anchor for fixing a scaffold formed on the outer wall is used. The grip anchor is embedded and fixed in a fixing hole provided in the outer wall. The grip anchor has a screw hole into which a screw for fixing the scaffold is screwed, and the hole filling device 1 is used to insert the screw hole to fill the fixing hole.
3 to 5 are schematic diagrams showing a hole filling method using the hole filling tool 1. As shown in FIGS. 3 to 5, a fixing hole H is provided in the outer wall W, and the grip anchor 2 is fixed to the fixing hole H. The hole filling tool 1 is inserted into the grip anchor 2 when the scaffold is disassembled after the operation is completed, and fills the fixing hole H. Here, the head 10 of the hole filling tool 1 has a size to close the fixing hole H.
The grip anchor 2 has a cylindrical shape, and is provided with a female screw portion 22 on the inner wall from one end to the center. The inner diameter of the female screw portion 22 is substantially equal to the outer diameter of the male screw portion 12 of the hole filling device 1, and the male screw portion 12 and the female screw portion 22 are dimensions to be screwed together. The grip anchor 2 is arranged with one end facing outward, and is fixed to the fixing hole H by the other end expanding radially.

As shown in FIG. 3, the distal end of the main body 11 is aligned with the opening on one end side of the grip anchor 2 and inserted. A solidifying liquid such as a caulking material or an adhesive may be put inside the grip anchor 2 before the hole filling tool 1 is inserted.

Used to fill (screw holes).

  The head 10 includes a thick boss portion 16 and a thin overhang portion 17 provided so as to project outward from the entire circumference of the boss portion 16, and is formed in a large-diameter disk shape. ing. The outer diameter of the boss portion 16 is smaller than the opening diameter of the target fixing hole H, and the outer diameter of the overhang portion 17 is larger than the opening diameter of the fixing hole H.

  The main body 11 includes an inner shaft 18 and an outer cylinder 19. One end of the inner shaft 18 is continuous with one surface of the boss 16 of the head 10. The outer cylinder 19 is connected to the other end of the inner shaft 18 extending coaxially with the head 10 so as to be folded toward the head 10.

  FIG. 13 is a cross-sectional view of the main body 11, and shows a cross section taken along line AA in FIG. As shown in the figure, the inner shaft 18 has a rectangular cross-sectional shape. The outer cylinder 19 is a partial cylinder that constitutes a part of a cylindrical body that surrounds the outside of the inner shaft 18 with a gap therebetween, and a pair of the outer cylinders 19 is provided at axially symmetric positions. The inner surface of the outer cylinder 19 is a flat surface that is parallel to each other, and faces each of the two opposing surfaces of the inner shaft 18 with a gap.

  As shown in FIG. 12, the outer cylinder 19 has a barrel-shaped shaft cross-sectional shape that has a maximum diameter at a central portion in the axial direction and continuously decreases in diameter toward both ends. On the surface, the same male screw portion 12 as in the first embodiment is provided.

  The hole filling tool 1 of the fourth embodiment having the above configuration is formed of a resin material having high elasticity, such as an ABS resin or a polyvinyl chloride resin, as in the first embodiment. As described above, the inner surface of the outer cylinder 19 is a flat surface facing in parallel, so that the hole filling tool 1 uses a molding die that is split in two in the direction along the inner surface of the outer cylinder 19. Can be integrally formed including the external thread portion 12 on the outer periphery.

  By applying an inward force, the outer cylinder 19 of the main body 11 is supported by a tip end connected to the inner shaft 18 and elastically bends and deforms in a direction to narrow a gap between the outer shaft 19 and the inner shaft 18. Due to this deformation, the outer diameter of the outer cylinder 19, that is, the outer diameter of the main body 11, becomes smaller. The head 10 of the main body 11 has a thin overhang 17, and the overhang 17 is bent and deformed by applying a force in the thickness direction to the periphery.

The overhanging portion 17 can be deformed in the thickness direction, and is deformed as shown in FIG. 14 when the hole filling tool 1 is pushed in, and elastically adheres to the wall surface around the fixing hole H. Accordingly, it is possible to prevent rainwater from entering the inside of the fixing hole H, and to suppress damage to the fixing hole H such as rust of the grip anchor 2. The head 10 may have a shape other than a circle such as an ellipse or a polygon. However, in the case of a circle, the degree of deformation due to the pressing becomes uniform over the entire circumference, and the infiltration of rainwater can be effectively prevented. .

  In order to more reliably prevent infiltration of rainwater, a seal member 20 indicated by a two-dot chain line in FIGS. 12 and 13 can be used. The illustrated seal member 20 is an annular plate packing, and is provided on one surface of the head 10 connected to the main body 11 so as to surround the periphery of the overhang portion 17. In the filled state shown in FIG. 14, the sealing member 20 provided in this manner resiliently contacts a wall surface around the opening of the fixing hole H to perform a sealing function. The sealing member 20 may be an O-ring wound around the base of the main body 11 connected to the head 10 and elastically contacting the inner surface of the fixing hole H to perform a sealing action. The large-diameter head 10 and the seal member 20 can be applied to the first, second, and third embodiments, and a similar effect of preventing rainwater from entering the inside of the fixing hole H can be obtained.

  Furthermore, according to the hole filling tool 1 according to the fourth embodiment, it is possible to fill a fixed hole formed at a non-perpendicular to the wall surface. FIG. 15 is a schematic diagram illustrating a state where a non-perpendicular fixing hole is filled by the hole filling tool 1 according to the fourth embodiment.

  The fixing hole H shown in the figure is formed at a right angle to the wall surface of the outer wall W. In the hole filling device 1 according to the fourth embodiment, the pair of outer cylinders 19 of the main body 11 has a barrel-shaped axial cross-sectional shape, and each of the outer cylinders 19 is fixed to the inner surface of the fixing hole H at different positions in the axial direction. As shown in the figure, the center line X of the main body 11 can be pushed while being inclined with respect to the center line Y of the fixing hole H. By this pushing, the hole filling tool 1 causes the one (lower in the figure) outer cylinder 19 to be more flexibly deformed and deformed than the other (upper in the figure) outer cylinder 19, and keeps the inclination, and the fixing hole H is formed around the opening. The hole is filled in a form equivalent to that of FIG.
