DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0003]

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. Met.

[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. However, there is a disadvantage that the anchor bolt 9 is not sufficiently driven and cannot be fixed, and the anchor bolt 9 that is hit and struck causes the stones and the like around the anchor bolt 9 to be distorted, resulting in brittleness and 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 extremely dangerous if there was a vibration such as an earthquake due to insufficient strength of the stones and other objects.

Therefore, according to the present invention, even in a narrow space formed between stone materials, the anchor can be extremely easily mounted on the inner wall surface of the stone material, and the anchor can be formed even by strong vibration such as an earthquake. An object of the present invention is to provide an anchor which does not swing and does not fall off from a stone material and is firmly fixed for a long period of time.

[0008]

According to the present invention, in order to solve the above-mentioned problems, a projection having an elliptical insertion hole is integrally formed and a circular through hole is formed at three places. A substantially semi-circular fixing bracket, a U-shaped member including an upper piece having an insertion hole formed therein and a lower piece having a groove formed therein, and the lower piece being inserted through an insertion hole formed in the upper piece. And a connector consisting of a pin which can be inserted into and detached from the U-shaped member. The connector can be attached to and detached from the protrusion of the fixture. An anchor, wherein a cut groove having substantially the same shape and the same size as the circular arc of the circular portion is formed, and an adhesive is injected into the cut groove to insert and fix the fixing bracket into the cut groove. A protrusion with an elliptical insertion hole is integrally molded, and a plurality of circular through holes are formed at three locations. A perforated substantially semi-circular fixing bracket and an insertion hole with a thread formed in the circular part at the tip and an upper piece and a thread with a thread formed in the circular part at the tip A connecting member comprising a curved U-shaped member made of a lower piece and a pin that can be screwed into an insertion hole formed in the upper piece and the lower piece having the circular portion. The connecting tool can be attached and detached, and the mounting on the wall surface is formed by using a rotary polishing plate to form a cut groove having substantially the same shape and the same size as the arc of the semicircular portion of the fixing bracket, and injecting an adhesive into the cut groove. An anchor, characterized in that a fixing bracket is inserted and fixed in the cut groove, and a projecting bolt having a thread formed on an outer peripheral surface thereof is projected, and circular through holes are drilled at three places. It is screwed into one end of the cylindrical part with the circular fixing bracket and the screw hole formed inside. With polygonal section is continuously provided which are formed over a substrate annulus insertion hole is formed is made of couplings which are continuously provided to the other end,
The connecting tool can be attached to and detached from the protruding bolt of the fixing bracket, and for attachment to the wall surface, a notch groove of the same shape and size as the arc of the semicircular part of the fixing bracket is formed by a rotary polishing plate and adhered to the notching groove An anchor is characterized in that an agent is injected and the fixing fitting is inserted and fixed in the cut groove.
