Abstract

PROBLEM TO BE SOLVED: To easily install anchors on a stone material by providing a fixing metal fitting of which projected part with drilled inserting hole is formed integrally, a channel-shaped member with upper and lower pieces, and a pin to connect the fixing metal fitting to the channel-shaped member. SOLUTION: A projected part 2 in which round through holes 1b, 1c, and 1d are drilled and an oval-shaped inserting hole 2a is drilled is formed integrally on a semi-circular fixing metal fitting 1a. Also, a flat plate is bent to channel- shape so as to form a channel-shaped member 3a, a through hole 3b is provided in the upper part of the channel-shaped member 3a, and a groove 3c is provided in the lower part of it so as to form a connecting device 3. In addition, to form an anchor 1, after a projected part 2 is arranged between the upper piece 3e of the channel-shaped member 3a and the lower piece 3f of it, a pin 3d is inserted into an inserting hole 2a in the projected part 2, and a top end part is fitted closely into the groove 3c in the lower piece 3f, and a connecting device 3 is connected to the fixing metal fitting 1. Thus the anchor can be installed easily on an inner wall surface of a stone material even in a small clearance formed between the stone materials.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an anchor for connecting and fixing stone and stone or stone and concrete.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 12, when a steel slab lid 6 is attached to the upper ends of a left stone 4 and a right stone 4a, an anchor having a chain 5 attached to the inner wall surface of the left stone 4 is used. Driving a bolt to connect the chain 5a attached to the lower surface of the steel sash lid 6 and the chain 5 attached to the anchor bolt 9 to form the left stone 4 and the right stone 4a
Is attached to the upper end of the steel.

However, when there is a narrow space between the left stone 4 and the right stone 4a, it is extremely difficult to drive the anchor bolts 9 having the chains 5 into the inner wall surfaces of the left and right stones 4, 4a.

[0004] In particular, when a steel lid, a stone lid, or the like is attached to and fixed to a box-shaped stone so as not to be detached, the box-shaped stone is connected to an anchor bolt 9 having a chain. The anchor bolts 9 were manually driven in for the method of driving and fixing the anchor bolts 9 to the inner wall surface of the stone. For this reason, there is a disadvantage that the anchor bolt 9 cannot be driven into an accurate position.

Further, when the anchor bolt 9 is beaten and driven into a stone material, a concrete or the like, the periphery of the driven portion collapses, and the driven anchor bolt 9 spreads, and the anchor bolt 9 is spread. However, there is a disadvantage that the anchor bolt 9 is not sufficiently driven and cannot be fixed, and the stones around the anchor bolt 9 are distorted by the anchor bolt 9 that has been hit and struck, resulting in insufficient strength.

Further, when the anchor is fixed with a mortar or the like, a difference in density of the mortar occurs due to a long-term difference in temperature and temperature, and the density difference causes distortion in the stone material. It was very dangerous if there was a vibration such as an earthquake due to lack of strength against the stone materials.

DISCLOSURE OF THE INVENTION The present invention can be easily mounted on the inner wall surface of a stone, even in a narrow space formed between the stones. Another object of the present invention is to provide an anchor in which the anchor does not swing and does not fall off the stone material, and is firmly fixed for a long period of time.

[0008]

SUMMARY OF THE INVENTION The present invention is characterized in that it comprises a fixing bracket integrally formed with a protruding portion having an insertion hole formed in a semicircular portion, and a connecting bracket composed of a U-shaped member and a pin. The structure of the anchor is as follows.

[0009]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a front view of a fixing plate constituting an anchor according to the present invention, FIG. 2 is a bottom view thereof, and FIG. 3 is a perspective view thereof.

And a protruding portion 2 integrally molded with the semicircular portion of the above.
Circular through holes 1b, 1c, 1
In addition to the hole d, an elliptical insertion hole 2a is formed in the protrusion 2.

In FIG. 1, FIG. 2 and FIG. 3, three circular through holes 1b, 1c and 1d are formed in the fixing bracket 1a, but the number of the through holes 1b, 1c and 1d is three. It is not limited to the location and may be increased or decreased as needed. That is, it may be provided at one location or at four or more locations. Further, the shape of the through holes 1b, 1c, 1d may be a square, an ellipse, or a polygon other than a circular hole.

FIG. 4 is a perspective view of the connector 3 constituting the anchor according to the present invention. The connecting member 3 includes a U-shaped member 3a.
And a pin 3 detachably attached to the U-shaped member 3a.
d.

The U-shaped member 3a is manufactured by bending a flat plate into a U-shape, and an insertion hole 3b for inserting a pin 3d is formed in the upper part of the U-shaped member 3a. And the pin 3d is provided below the U-shaped member 3a.
Is formed with a groove 3c into which the lower end can be fitted.

FIG. 4 shows a structure in which a pin 3d is inserted into an insertion hole 3b formed in the upper piece 3e of the U-shaped member 3 and the tip of the pin 3d is fitted into the groove 3c. A screw thread may be formed in the insertion hole 3b formed in the shaped member 3a, and a screw thread may be formed in the pin 3d, and the pin 3d may be screwed.

In FIG. 4, a groove 3 is formed in a lower piece 3f of the U-shaped member 3a.
Although c is provided, such a groove 3c may not be provided. By providing the groove 3c, the pin 3d does not swing because the lower end of the pin 3d is fitted, and the pin 3d is stabilized.
