Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an asbestos slate roofing board.

Conventionally, a mounting bracket C as shown in Fig. 8 has been used to attach the gutter B to the asbestos slate roofing plate A, but this method of clamping the plate does not require a clamping method. If the force was even slightly weak, it would tend to shift laterally, and every time a typhoon hit, the gutters would bend or become detached from the water collectors.

Therefore, the inventor thought of drilling a hole in the roofing plate, attaching a metal fitting to the hole, and fixing the gutter with this metal fitting. However, since the gutter can only be installed after the roofing is completed, the holes for installing the gutter cannot be made until after the roofing is completed. For this reason, I had to carry a power drill with me, but since the roofing board is made of asbestos slate, there is a risk of it breaking if it is easily lifted and hit with a power drill, or the cord of the power drill is cumbersome to route, making it difficult to use for roofing. As a result, the construction work took a lot of time and effort. Furthermore, there is a risk that the cord may get caught in an unexpected place, causing an accident. However, battery-powered electric drills were not suitable for long hours of work. In view of the above, an object of the present invention is to provide a drilling tool that is convenient to carry around and that can reliably drill holes even in asbestos slate roofing plates.

Hereinafter, an explanation will be given with reference to an embodiment shown in the drawings. FIG. 1 is a partially cutaway front view. In the figure, 1 is a guide plate, 2 is an insert plate, and the guide plate 1 and the insert plate 2 are connected. The drawing boards 1 and 2 are connected substantially in parallel by a portion 3, and a gap is formed between the drawing boards 1 and 2, which is slightly larger than the thickness of the roofing board, and the whole has a U-shape.

The inner surface of the tip of the guide plate 1 and the insertion plate 2 has a gradually expanding tapered part 4.
a and 4b, and the tip of the lower surface of the insertion plate 2 is set at an acute angle to facilitate insertion between the roofing plates A. The tip of the guide plate 1 is provided at a position slightly set back from the tip of the guide plate 2. A holding cylinder 5 is erected on the upper surface of the guide plate 1 near the tip, and a punch 6 is provided inside the holding cylinder 5 so as to be movable up and down. The lower end of the punch 6 is the guide plate 1 and the insertion plate 2.
It is designed so that it can be fitted into punch holes 7a and 7b formed to penetrate therethrough. The lower surface side of the punch hole 7b formed in the insertion plate 2 is gradually expanded and opened, so that the punch waste can be easily taken out without becoming clogged. Further, the upper end of the punch 6 projects above the holding tube 5 to form a striking portion 8. The punch 6 is biased upward by a spring 9, so that the punch 6 returns upward immediately after being lowered. A stopper 10 is provided at the center of the guide plate 1 and the insert plate 2 to keep the insertion amount of the insert plate 2 into the roofing plate constant.

Although there may be one stopper 10, a plurality of stoppers 10 may be provided so as to be selectable depending on the purpose of use and the place of use. A handle 11 is provided at the rear end of the guide plate 1. FIG. 2 is a plan view of the embodiment shown in FIG.

3A and 3B show another embodiment of the stopper part, in which a stopper rod 12 is screwed into the connecting part 3, and by turning this stopper rod 12, the roofing of the insert plate 2 is removed. There is a device to adjust the amount of insertion into the plate A. 12a is a receiving plate, 1
Reference numeral 2b is an elastic material, and the receiving plate 12a and the elastic material 12b are arcuate and protrude at the center.

Incidentally, the stopper rod 12 may be provided with a scale for adjusting the insertion amount. FIG. 4 shows another embodiment of the handle, in which the handle has a substantially right triangular shape, and the handle has a grip portion 13.
A hook 14 for a splint finger is formed.

In addition, a part of the annular handle is provided with a cut-off part 15, so that when the punching tool is hung on the rod, there is no need to hang it from the end of the rod. You can even apply it! Also, when inserting the handle, the impact applied to the grip portion 13 of the handle can be alleviated. Fifth
The figure shows another embodiment of the punch hole 7b of the insertion plate 2, in which a depressed portion 16 is formed around the lower surface of the punch hole 7b.

This depressed portion 16 is formed in a shape that gradually expands downward.
Punch waste is prevented from clogging the punch hole 7b. To make a hole using the punching tool of the present invention, insert the insert plate 2 under the roofing plate A as shown in FIG. When struck with a hammer, the tip of the punch 6 is driven down to the insert plate, and a hole corresponding to the cross-sectional shape of the punch 6 is punched in the roofing plate A.

After striking, the punch 6 is pushed upward by a built-in spring 9. When the punching is completed, the seventh
As shown in the figure, lift the roofing plate A by holding the handle 11 of the drilling tool, and attach the metal fitting C for fixing the gutter B, etc. The present invention provides an insertion plate whose bottom end is formed at an acute angle, a guide plate whose front end is provided at a position slightly set back from the front end of the insertion plate, and the guide plate and the insertion plate. A guide plate and an insert plate are arranged in parallel and connected at a connecting part at the rear end with a gap slightly larger than the thickness of the roofing plate formed between the two, into which the roofing plate is inserted. A stopper is provided at the rear of the gap between the guide plate, a holding cylinder is provided upright near the tip of the upper surface of the guide plate, and a handle is provided at the rear end of the guide plate, and a punch is provided within the holding cylinder so as to be movable up and down. the punch has an upper end serving as a striking part, the striking part projects upward from the upper end of the holding cylinder, and the punch is biased upwardly by a spring;
The tip of the punch can be inserted into a punch hole formed concentrically through the guide plate and the insertion plate, and the punch hole provided in the insertion plate is formed to gradually expand downward. Therefore, the drilling work can be easily carried out without breaking the asbestos slate roofing plate after roofing is completed, and the work can be done safely. In other words, a slightly longer insert plate is formed in front of the guide plate, and the tip of the lower surface of this insert plate is formed at an acute angle, so that the lower surface of the asbestos slate roofing plate after the roof is covered. The insertion plate can be easily inserted from the tip of the insertion plate, and the length of insertion of the roofing plate into the drilling tool can be kept constant with a stopper. By moving the punch while remaining in the punched hole in the plate, this swarf can also be removed and the gutter fitting can be installed. Furthermore, since the punch is biased upward by a spring, the punch can be removed immediately after punching, and since there is a handle on the rear end, the punch can be moved safely even on the roof. This is possible.
