Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for attaching an ALC panel or the like to a body as an outer wall of a building.
The present invention relates to a drilling jig used to form a hole for burying an anchor for screwing into a panel.

[0002]

2. Description of the Related Art As a construction method for attaching an ALC panel or the like to a frame as an outer wall of a building, for example, as shown in FIG.
There is a dry method in which this metal fitting is attached to a ruler angle that is fixed to the building frame beam. Mounting bracket 25 for this method
As the means for screwing on, the long side edge face 21 of the panel 21
-1 is formed in a direction perpendicular to -1 in parallel with the panel surface and is slightly deeper than the panel center by using a long drill, and then drills a bolt hole 23 orthogonal to the hole 22 from the back surface of the panel. Then, the long edge of the panel 21-
From the anchor embedding hole 22 opening to 1, a pipe-shaped anchor 24 having a screw hole formed in the center is inserted, and from the bolt hole 23 opening to the back surface of the panel,
A bolt 26 inserted through the mounting bracket 25 is inserted and screwed into the screw hole.

[0003]

According to this construction method, since there is no through hole in the panel surface, there is no possibility of flooding from the through hole or cracking on the panel surface. When the hole 23 is drilled, the flexibility of the drilling position is poor, and when drilling at a construction site, it is possible to drill at a desired position, but a depth of 400 mm from the front face of the panel having a thickness of about 100 mm. There is a problem in that it requires a high degree of skill and takes time to form the anchor-embedding holes 22 of a certain degree with high positional accuracy and further to bore the bolt holes 23 from the back surface of the panel toward the holes to make them orthogonal to each other.

The present invention has been made in order to solve the above-mentioned conventional problems, and an anchor embedding hole formed in a direction perpendicular to the fore edge of the long side of the panel and a bolt hole orthogonal to the hole from the back surface of the panel. An object of the present invention is to provide a panel punching jig that can be easily formed with high positional accuracy.

[0005]

A jig for piercing a panel according to the present invention can be easily attached to and detached from a front surface of a panel and a small-edge face (side surface) of a long side by a concavo-convex fitting method, and can be fitted to a panel. This is a jig that can fix holes with anchors in the small side of the long side and bolt holes on the back side of the panel in a fixed state without any trouble, and its gist is a jig longer than the panel width. At both ends of the main body, a gripping mechanism is provided for sandwiching the facing long side edge face of the panel and fixing the jig body in a direction perpendicular to the edge face, and at one end of the jig body, the anchor is provided. It has a guide mechanism that guides the drilling blade for forming the buried hole in the longitudinal direction of the jig body, and is characterized in that a long hole for drilling a bolt hole is provided on the center line of the upper surface of the jig body. , One of the gripping mechanism is fixed to the jig body, and the other is Together they form a screwed possible jig body is slidably mounted longitudinally to the jig body,
The gripping part is provided with a pressing mechanism that applies a constant panel pressing force according to the panel width with a spring, and the guide mechanism has an inner diameter slightly larger than the diameter of the anchor burial hole to be formed. In addition, a guide cylinder having a notch on the bottom surface is provided, and the jig body is detachable.

In the gripping mechanism according to the present invention, an L-shaped metal fitting which comes into contact with the front surface of the panel and the long side edge surface is attached to the back surface of the jig body longer than the panel width, that is, the surface facing the panel surface. In this case, the L-shaped metal fitting on the side where the anchor embedding hole is formed on the long side edge is fixed to the jig body, and the L-shaped metal fitting on the opposite side slides to a predetermined position so as to correspond to the panel width. It is possible. That is,
In the gripping mechanism of the present invention, one is a fixed gripping part and the other is a movable gripping part.

The guide mechanism of the perforating blade provided on the L-shaped metal fitting which constitutes the fixed grip portion is detachably attached to the jig main body with bolts or the like so as to come into contact with the vertical surface which abuts the long side edge surface of the L-shaped metal fitting. In the bracket, attach a guide cylinder that has an inner diameter slightly larger than the diameter of the anchor embedding hole and has a notch on the bottom surface at a position that matches the center line of the jig body, The bracket, the guide cylinder, and the L-shaped metal fitting are penetrated to guide the jig body at a right angle to the longitudinal direction.

The reason why the guide mechanism for the perforating blade is detachable from the jig body is to cope with variations in the thickness of the panel. That is, when the thickness of the panel is different, the formation position of the anchor embedding hole naturally changes,
This is because the dedicated guide mechanism can be replaced and used according to the thickness of the panel. Further, the notch is formed on the bottom surface of the guide cylinder in order to smoothly discharge the panel chips generated during the perforation.

On the other hand, the movable gripping part has a pressing mechanism for pressing the L-shaped metal fitting against the panel edge surface, and the pressing mechanism is slid along a long hole formed on the center line in the longitudinal direction of the jig body to slide the panel surface. It is composed of a sliding mechanism that is fixed to. The pressing mechanism is provided with an L-shaped metal fitting slidably along an elongated hole formed on the upper surface of the jig body, and is integrally attached to the L-shaped metal fitting so that a pressing force is constantly applied to the fixed grip portion side. It is composed of a spring-equipped lever and an engaging metal fitting for removably locking the lever at a predetermined position, and the pressing force of the movable L-shaped metal fitting can be adjusted according to the variation of the panel width. There is.

Further, in the sliding mechanism, a set screw screwed to the engagement fitting is made slidable along an elongated hole formed in the upper surface of the jig body, and the set screw is used for the engagement metal. It has a structure that can be tightened and fixed to the jig body,
The movable L-shaped metal fitting can be fixed at a predetermined position according to the panel width.

The punching jig of the present invention is capable of holding the facing long edge of the panel by the fixed gripping portion and the movable gripping portion and fixing them in the right angle direction, and the same pressing force can be applied to panels having different widths. Can be fixed. In addition, the guide mechanism detachably provided on the fixed grip portion can hold the drilling blade (drill) at right angles to the long side fore surface of the panel, and the anchor embedding hole is formed accurately from the long side fore surface. be able to. Further, since the guide mechanism of the punching blade can be replaced, even if the thickness of the panel is different, it can be easily dealt with by using the guide mechanism adapted to the thickness. Further, the bolt hole orthogonal to the anchor embedding hole can be accurately drilled from the panel surface by utilizing the long hole drilled in the jig body.
