Description

[Detailed description of the invention] The present invention relates to a fastening hardware for brickwork that is used to fasten the brick side to reinforcing bars poured onto the concrete base at key points when applying wet bricks to a concrete base. It is.

Conventionally, when applying wet bricks to a concrete base,
When bonding the brick side to reinforcing bars installed on the base concrete side at key points, as shown in Fig. A metal wire 5 was wrapped around a metal rod 4 inserted into the hole, and the wires were tied together by twisting both ends.

However, in such a structure, although the metal wires 5 are securely bound outwardly, they are unstable because there is no holding force on the adjacent side, and the metal rods 4 as dowels are only tied to the bricks 3. It is difficult to check the length of the knot, and it tends to be biased to one side, which may reduce the binding force.

This invention was made to eliminate the above-mentioned drawbacks.
By forming one protrusion or two protrusions close to each other at a predetermined point on the outer circumferential surface of a metal rod, and rotatably connecting a band-shaped member with one end attached to a reinforcing bar to this metal rod, the tightening work can be performed. To provide a fastening hardware for brick pasting that is easy to hold, can be held accurately, and provides sufficient fastening force.

The present invention will be explained in detail below based on the illustrated embodiments.

Figures 2 and 3 show an embodiment of the present invention.
1 is a metal rod for connecting bricks, 12 is a band-shaped fastening member,
Both are made of stainless steel, for example.

The metal rod 11 has a locking protrusion 11a in its middle part.
One or two are formed close to each other, and both sides thereof are inserted into small holes in the brick 3 to function as dowels, as shown in FIG.

In addition, the fastening member 12 is formed by twisting a tapered metal band at a right angle at a predetermined point, and a hole 12b through which the metal rod 11 is inserted is bored at the vertical end, and the tapered horizontal end side is , and serves as a trapping part 12a for tightening the reinforcing bar 1.

The fastening member 12 and the metal rod 11 are integrally assembled by rotatably passing the metal rod 11 through the insertion hole 12b, and can be positioned in the axial direction by the protrusion 11a.

Thus, the fastening hardware for brickwork according to the present invention is used as shown in FIG. 3 when wet brickwork is applied to a concrete base.

That is, a metal rod is inserted into the small hole of the brick 3 to be pasted onto the mortar 2, and when the member 12 is in contact with the protrusion 11a or is fitted and locked between two protrusions, the metal rod is attached to the brick 3. After checking the swallowing length of the
2a is placed on the reinforcing bar 1 provided on the concrete base side, and when twisted, it becomes a tight state.

As mentioned above, this invention is based on a brick connecting metal rod having a required length and having a locking protrusion 11a at a predetermined portion and having a thickness that can be inserted into a small hole drilled in a brick 3. 11, and a trapping part 12 which has an insertion hole 12b for the metal rod 11 at one end, and whose other end, which is formed into a tapered shape, is twisted at a required point and attached to the reinforcing bar 1 on the concrete base side.
Since the metal bar 11 is restrained and positioned relative to the binding member 12 in the length direction (axial direction), the brick of the metal bar 11 The swallowing length into 3 becomes stable, and sufficient tightening force can be obtained.

Furthermore, the fastening member 12 can be easily interposed between joints by vertically inserting the metal band perpendicularly to the metal rod 11, and the length of the fastening member 12 can be adjusted at will when attached to the reinforcing bar by the catching part. After bondage, the position of the metal rod is stable and the accuracy of brick attachment is improved.

In addition, the tying work becomes easier, and by bringing the tying member out before tying, it is possible to prevent forgetting to lace.
