Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel bar assembly for bar arrangement, and more particularly to a bar steel assembly for bar arrangement which is convenient for transportation and storage and can perform bar arrangement with high accuracy.

[0002]

2. Description of the Related Art Steel bars are arranged at predetermined intervals in order to maintain strength during concrete pouring in building construction, port facility construction, bridge construction, etc., and the material of the steel bars used at that time. , Diameter, spacing of reinforcing bars, etc. have a significant effect on the strength of the concrete frame to be made, so they are strictly specified.

[0003] Conventionally, in this bar arrangement work, a steel bar designated at the site is carried, and the steel bars are arranged at the site vertically, horizontally, and at designated intervals according to the design drawing, and the intersections thereof are bound with a wire or the like. It was carried out by doing.

[0004]

[Problems to be Solved by the Invention] Although a rebar work at this site is carried out by a professional craftsman called a rebar worker,
Not only is it very labor-intensive, it is also very difficult to maintain the accuracy of the bar arrangement, and the bar arrangement is apt to be disturbed, which is a major problem in terms of maintaining the strength of the concrete frame. In addition, when arranging bars, it is inevitable that overlapping portions will be formed between the steel bars, and there is a problem in terms of effective utilization of the material (steel bars).

Therefore, in order to improve the accuracy of the work of arranging,
Attempts have also been made to reduce the amount of work in the field and maintain the accuracy of the bar arrangement by producing a bar arrangement grid body in which steel bars are combined in a grid shape in advance and carrying it to the site. This method is effective in maintaining the accuracy of the bar arrangement and improving the work efficiency, but the grid body assembled in advance in the factory is bulky, requires a large space for transportation and storage, and is difficult to handle.

An object of the present invention is to solve the above-mentioned problems relating to the bar arrangement during concrete pouring, and the bar can be accurately arranged at the intervals as designed, and on-site work is simple and It is an object of the present invention to provide a convenient steel bar assembly for bar arrangement, which can be transported and stored extremely efficiently.

SUMMARY OF THE INVENTION According to the present invention, a plurality of steel bars 1 having the same diameter and the same length are connected with a cord 2 in an avalanche shape so that when they are extended, they are parallel to each other at a predetermined distance L. To solve the above problems, and similarly,
The steel bars 1 are fixed to each other by a plurality of metal rods 6 so that the steel bars 1 are arranged in parallel at a predetermined distance L, and the unit lattice bodies 3 are connected to each other by a string material 2 so as to keep the predetermined distance L in series. It aims to solve problems.

[0008]

In the invention described in claim 1, since it can be wound like a reel as shown in FIG. 3 during transportation and storage, it is extremely compact. On the other hand, at the time of use, if the bar-shaped member 1 is stretched so that the steel bars 1 are parallel to each other, the bar materials 1 are regulated by the string material 2 and the steel bars 1 are accurately aligned at a predetermined interval L. It Therefore, by arranging the extended state vertically and horizontally and binding the intersections, the work prior to the concrete pouring can be completed. Further, in the invention according to the second aspect, when the cord material 2 is folded at the bending point as shown in FIG. 6 during transportation and storage, the cord material 2 can be stacked at a high density. Furthermore, since the interval L between the steel bars 1 is regulated by the metal bar material 6, more accurate and stable bar arrangement is possible.

[0009]

FIG. 1 is a plan view of an embodiment of a steel bar assembly for bar arrangement according to the present invention. In the figure, 1 is a steel bar having a predetermined diameter and a predetermined length (mostly 3 to 7 m).
When the steel bars 1 are extended, they are connected to each other by a plurality of cords 2 in an avalanche shape so that they are aligned in parallel at predetermined intervals L in parallel. The cord 2 is preferably made of a material having little expansion and contraction, and synthetic resin such as polypropylene resin and polyamide resin can be used. Further, a metal wire such as a steel wire having high flexibility may be used. .

In this embodiment, the distance L between the steel bars 1 is L.
Is 200 mm, but it is needless to say that this interval L can be arbitrarily set according to the pitch at the time of bar arrangement. This embodiment has the configuration as described above, and when it is transported or stocked, it can be made extremely compact if it is wound in a reel shape as shown in FIG. On the other hand, at the time of use, if the bar-shaped member 1 is made to extend in parallel with the bar-shaped members 1 to be parallel, the bar-shaped members 2 are regulated by the cords 2 and the bar-shaped members 1 are accurately aligned in parallel at predetermined intervals. As shown in FIG. 4, the reinforcement work can be completed simply by arranging them vertically and horizontally and binding the intersections. In FIG. 4, 4 is a skeleton, and 5 is a pillar.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, a plurality of metal rods 6 are arranged so that the steel bars 1 are arranged in parallel at a predetermined pitch L.
Are vertically combined and each intersection is fixed by welding or other method, and a plurality of unitary lattices 3 are vertically aligned, and the unit bodies 3 are connected to each other with a string 2 so as to have a predetermined interval L. There is. The material and the like of the cord 2 are the same as those of the first embodiment described above, and the description thereof is omitted here. The distance between the steel bars 1 and the distance L between the unit bodies 3 are the same as the pitch at the time of bar arrangement, as in the case of the above-mentioned embodiment.
The metal rod 6 merely holds the distance L between the steel bars 1 and does not bear the strength of the reinforced concrete, so there is no problem even if it is a thin rod or wire having poor rigidity. This embodiment has the configuration as described above, and by folding the cord-shaped portion 2 as a bending point as shown in FIG. 6, it can be stacked at a high density, and transportation and storage space can be saved. Can be realized. Further, in this embodiment, the distance L is regulated by the metal rod member 6, so that more accurate bar arrangement is possible. In addition, if the vertical and horizontal lengths of the single grid 3 are made in advance so as to match the loading platform of the truck for transportation, no wasted space is produced during transportation,
It is even more efficient.

[0012]

EFFECT OF THE INVENTION The present invention has the above-described structure, and can be wound in a reel shape during storage and transportation, and can be folded to have a compact packing shape. By simply extending the cord material 2 and making the cord material 2 in a stretched state, a preset bar arrangement interval L can be easily obtained, and the bar arrangement work can be completed accurately, easily and quickly. It is extremely practical because it not only contributes to the shortening of the material but also has the economical effect of saving the material (steel bar) by reducing the overlapped portion during the rebar arrangement.
