[0002]

2. Description of the Related Art FIG. 8 is a front view showing a conventional example of a punching device.
FIG. 9 is a diagram illustrating a process of mounting an operating portion provided in the drilling device of FIG. 8 on a concrete wall, and FIG. 10 is a diagram illustrating a process of mounting a water receiver provided in the drilling device of FIG. 8 on a concrete wall. FIG. 11 is a view for explaining a step of making a hole in a concrete wall by the perforating apparatus shown in FIG.

[0003] A conventional drilling device shown in FIG.
For example, an adsorption fixed body 2 that can be adsorbed on the surface of a concrete floor 1, an adsorption packing 2a mounted on the entire lower surface of the adsorption fixed body 2, a surface of the concrete floor 1 and the adsorption fixed body 2
, A vacuum pump 5 for sucking air through the vacuum suction port 3 and the vacuum hose 4, a base plate 6a movably mounted on the adsorption fixed body 2, and a base plate 6a fixed on the base plate 6a and covered. A pillar 6 erected in a direction perpendicular to the surface of the perforated body, that is, the concrete floor 1, a movable support 7 movably provided along the pillar 6, and a handle 8 for moving the movable support 7; And a diamond core drill 9 attached to the movable support 7. In addition, the above-mentioned adsorption fixed body 2, the support 6, the base plate 6
The movable part 7, the handle 8, the diamond core drill 9, and the like constitute an operating part 11 that can be attached to and detached from the surface of the concrete floor 1 or the like.

Further, the above diamond core drill 9
, A blade 9b is attached via a spindle 9a,
The blade portion 9b faces the perforated portion 1a of the concrete floor 1, and since the tip of the blade portion 9b generates heat by the perforating operation, a water receiver 12 for receiving cooling water is arranged around the perforated portion 1a. ing. The water receiving body 12 has an annular portion 14 formed in an annular shape, and a rubber member 1 attached to a lower end of the annular portion 14 to seal a gap between the annular portion 14 and the perforated portion 1a.
The drain portion 16 penetrates the annular portion 14. The water receiver 12 is pressed by a pair of pressing members 17 attached to the base plate 6a, and the annular portion 14 is formed into the perforated portion 1a by tightening a bolt 17a for attaching the pressing member 17 to the base plate 6a. To be pressed. As a result, since the rubber member 15 comes into close contact with the perforated portion 1a, cooling water is received into the annular portion 14 in this state, and after cooling the tip of the blade portion 9b with the cooling water, the cooled water is removed from the annular portion 14a. The water is discharged from the inside through the drainage section 16.

[0005] The above-mentioned base plate 6a is attached to the adsorption fixed body 2.
One end of a screw rod 18 is screwed into the suction fixing body 2 so as to be movably mounted thereon, and the screw rod 18 is inserted into a long hole 19 formed in the base plate 6a. The nut 20 is screwed into contact with the base plate 6a.

In this conventional drilling device, the suction fixing body 2 is arranged on the surface of the concrete floor 1, and the vacuum pump 5 is operated to suck air between the surface of the concrete floor 1 and the suction fixing body 2. Thereby, the adsorption fixed body 2 is adsorbed on the surface of the concrete floor 1. As a result, the operating portion 11 is mounted on the surface of the concrete floor 1, and the columns 6 of the operating portion 11 are fixed via the adsorption fixed body 2 and the base plate 6a. Next, the base plate 6
After arranging the water receiving body 12 in the vicinity of a, each end of the pair of pressing members 17 is attached to the base plate 6a, and the other end is placed on the end of the water receiving body 12, and the bolt 17a is tightened. The annular portion 14 is pressed toward the perforated portion 1a by the pressing member 17, and as a result, the rubber member 15 comes into close contact with the perforated portion 1a. Next, the operator rotates the handle 8 to move the movable support 7 along the column 6 toward the surface of the concrete floor 1 while supplying the cooling water into the water receiver 12. Blade part 9b
Is pressed against the concrete floor 1. Then, a start switch (not shown) is turned on to rotate the blade portion 9b to make a hole in the perforated portion 1a of the concrete floor 1.

The vertically formed concrete wall 13
When drilling holes by the above-described drilling device, first, as shown in FIG. 9, after removing the tip of the vacuum hose 4 from the vacuum outlet 3 of the suction fixing body 2 and disposing the vacuum pump 5 on the concrete floor 1, An operator holds the supporting column 6 with one hand to support the operating portion 11, thereby pressing the suction fixing body 2 against the surface of the concrete wall 13, and in this state, holding the vacuum hose 4 with the other hand to suction and fix the vacuum hose 4. Vacuum outlet 3 for body 2
And the vacuum pump 5 sucks air between the surface of the concrete wall 13 and the adsorption fixed body 2,
The adsorption fixed body 2 is adsorbed on the surface of the concrete wall 13. As a result, the working part 11 is placed on the surface of the concrete wall 13.
Is mounted, and the support 6 of the operating portion 11 is
Is fixed to the concrete wall 13 via the adsorption fixing body 2 and the base plate 6a.
