Abstract

PROBLEM TO BE SOLVED: To attach a bolt to a reinforcing wall while simply adjusting a height position by threadedly mounting the bolt, which can move in the cross direction, in the shorter side of an L-shaped bracket metal body and tightening bolts for forming support pieces, which are projected from the upper and lower ends of a longer side so as to hold the reinforcing wall with the bolt. SOLUTION: A flat and nearly L-shaped bracket metal body 1, a receiving metal, is arranged so as to be held by support pieces 4 or the like and a bolt 2 at a specified height of a reinforcing wall A and is fixed by the bolt 2. The end of an ornamental reinforcing bar B in the reinforcing wall side is placed on the upper side face of the metal fixture body 1 between the reinforcing wall A and a projected piece 5, the other end is placed on the spacer on a slab mold. After arranging ornamental reinforcing bars along a beam leaving a specified space between them, main reinforcing bars are placed on these ornamental and the coiled by a steel wire. After that, stirrup reinforcing bars are mounted on it leaving a specified space between them to assemble a reinforcing beam, and the reinforcing beam is buried in concrete together with reinforcing bar as it is.

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 receiving a kansashi bar for maintaining a height position of an upper main bar of a beam having a wall on one side in a steel bar construction.

[0002]

2. Description of the Related Art Conventionally, in the case of a beam having a wall on one side, as a method of disposing a kansashi bar, one end of the kansashi bar is directly wound around a required height position of the wall bar with a steel wire such as a wire. And the other end was placed on a spacer arranged on a slab formwork.

[0003]

In the above conventional method,
A steel wire such as a wire is directly wound around the end of the kansashi muscle on the wall muscle side at the required height position of the wall muscle and fixed, but multiple beam main bars are placed on the kansashi muscle In addition, it lacks reliability in terms of supporting strength of load applied at the time and construction accuracy, and has a serious problem such as anxiety in work safety.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to easily, reliably and accurately mount a kansashi muscle at a predetermined height of a wall muscle. The object of the present invention is to provide a metal fitting for kansashi muscle which can be made.

[0005] As a means therefor, a supporting piece which is screwed to the short side of a substantially L-shaped bracket main body in the left and right direction and which protrudes from upper and lower ends of the long side so as to sandwich a wall line with the bolt. Are formed opposite to each other, and a protruding piece for hooking a kansashi muscle is formed on at least one of the tips, and one or more through holes are formed in the metal fitting body. I do.

[0006] With the above structure, a bolt which can be moved left and right is screwed onto the short side of the metal body having a substantially L-shape in plan view, and the support piece protrudes from the upper and lower ends of the long side so as to sandwich the wall with the bolt. By forming bolts facing each other,
The wall reinforcement can be easily adjusted to the required height position and mounted, and a stable supporting strength can be obtained. By forming the protruding piece for hooking the kansashi at the end of the long side, the kansashi can be received on the side of the bracket main body and can be securely mounted without side slip. In addition, by providing one or more through holes in the metal fitting body, using the through holes, the kansashi muscle is wound around the metal fitting body with a wire, so that the kansashi muscle is more reliably supported. Thus, the above-mentioned conventional problems can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a side view showing an embodiment of the present invention. Reference numeral 1 denotes a bracket body having a substantially L-shaped flat surface, and a bolt 2 capable of moving back and forth to the left and right is screwed to the short side. Reference numerals 3 and 4 denote support pieces protruding from the upper and lower ends of the long side, and are formed in such a manner that the wall striking portion has an arc shape so as to enclose the wall striation. Reference numerals 5 and 6 denote projecting pieces for hooking the kansin stripes, which are formed to protrude vertically from the ends of the long sides. By projecting in both the up and down directions, the directivity when attaching the bracket main body is eliminated, thereby facilitating the attachment. However, a projecting piece may be formed only on one side. Reference numerals 7 and 7 denote through holes formed at the tip of the fitting main body 1 and are provided in such a size that a wire can be inserted. Reference numeral 8 denotes a large-diameter through hole formed substantially at the center of the metal fitting body, which can obtain an effect of improving the circumference of concrete and can be used as an insertion hole for attaching a kansashi bar. Reference numerals 9 and 9 denote reinforcing pieces provided with the bolts 2 at the corners of the long side and the short side.

Next, a method of using the present invention will be described. FIG. 3 is a side view showing a use state of the embodiment of the present invention, and FIG. 4 is a partial sectional view showing a use state of the embodiment of the present invention. The receiving fitting of the present invention is arranged at a required height position of the wall streak A so as to be sandwiched between the support pieces 3 and 4 and the bolt 2, and the bolt 2 is tightened and fixed. One of the striated muscles B on the wall muscle side is placed on the upper surface of the fitting main body 1 between the wall muscle A and the projecting piece 5, and the other is placed on the spacer C on the slab formwork. If necessary, the kansin streaks and the bracket main body are wound and fixed using a wire with a wire. In the same manner, after placing kansushi bars at the required intervals along the beam, place the main bars on those kansashi bars, wind and fix them with steel wire, and then attach the stirrup bars at the required intervals. Assemble the beam reinforcement by assembling and bury it in concrete together with the steel reinforcement.

[0009]

As described above in detail, according to the wrought metal fittings for reinforcing steel of the present invention, bolts capable of moving back and forth to the left and right are screwed onto the short sides of the metal body having a substantially L-shape in plan view.
By forming support pieces protruding from the upper and lower ends of the long side so as to sandwich the wall studs with the bolts, the bolts are tightened, and easily adjusted to the required height position of the wall streak and attached. In addition, stable support strength can be obtained, and work efficiency and construction accuracy can be improved. By forming a protruding piece at the end of the long side for hooking the kansashi streaks, the kansashi streaks can be received on the side of the bracket main body, and can be securely attached without sliding down and falling. By drilling more than one through-hole, using the through-hole, the wire can be used to wrap the kansashi streaks around the metal fittings body, so that the kansashi streaks can be more reliably supported, It is possible to obtain a practically useful kansashi bar receiving bracket such that certain construction can be realized and safety can be ensured.
