[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for maintaining a spacing between base bars in a work for arranging a structure, particularly a foundation.

[0002]

2. Description of the Related Art Conventionally, a reinforcing bar supporting leg formed by bending a bar and formed into a gate shape, and both legs of the reinforcing bar supporting leg are fitted and supported as a reinforcing bar spacing tool for a base bar of a base portion. A method of using a holder made of a synthetic resin pedestal having two holes is disclosed, but as a method of use, after arranging a lower bar of the base bar on the discarded concrete, the pedestal is connected to the lower bar. It is placed at the required position and interval on the lower side, and the lower streak is placed on the pedestal. Next, while arranging the upper muscle of the base muscle on the arranged lower muscle, inserting the reinforcing bar support leg into the insertion hole of the pedestal already arranged, placing the upper muscle on the reinforcing bar support leg, and The interval between the lower muscle and the upper muscle is maintained.

[0003]

[Problems to be Solved by the Invention] In the above conventional method,
Since the fitting holes of the reinforcing bar support legs are two holes, the supporting direction of the reinforcing bar is limited to one direction. For example, the reinforcing bar of the upper bar and the lower bar is in a zigzag state like a staggered bar. In some cases, when placing the pedestal below the lower muscle, if the direction of bending of the reinforcing bar is not parallel to the direction of bending of the reinforcing bars, The upper muscle cannot be supported. Further, in some cases, a heavy reinforcing bar having a large diameter is used as the base bar, and there is a problem in that the conventional reinforcing bar spacing retainer lacks reliability in terms of strength and reliability.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to easily insert a reinforcing bar support leg into a fitting hole of a pedestal regardless of the direction of the reinforcing bar. It is an object of the present invention to provide a rebar spacing retainer for reliably and stably retaining the rebar spacing even with a base bar having a large rebar diameter and a considerable weight.

[0005] As means for this purpose, there is provided a reinforcing bar support leg formed by bending a bar into a gate shape, and a synthetic resin pedestal having a fitting hole for fitting and supporting both legs of the reinforcing bar support leg. In the rebar spacing holder, the fitting holes are formed at least two places at equal intervals in front, rear, left and right on the upper surface of the pedestal, and a protruding piece is formed on one side of the pedestal, and the protruding piece is formed on another opposite side. Are characterized in that the detachable hook pieces are formed integrally with each other.

According to the above structure, at least two or more holes are formed at regular intervals in front, rear, left and right on the upper surface of the pedestal, so that the reinforcing bars can be easily supported irrespective of the arrangement direction of the upper bars. Can be supported by legs. By forming the projecting piece on one side of the pedestal and integrally forming the engaging piece on the other side opposite to the projecting piece so that the projecting piece can be easily attached and detached, an appropriate number of rebar spacing holders can be easily connected. By connecting two to the left or right or connecting three diagonally (see FIG. 4), it is possible to easily cope with the weight of the rebar and stably maintain the interval between the rebars.
This is to solve the conventional problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, in which the outer contours of the upper surface from which unnecessary portions have been removed are removed at the four corners of a square synthetic resin pedestal 1 and below the upper surface of the pedestal 1. An insertion hole 2 having an appropriate length is formed, and the protruding projections 3 and 3 are detachable at both ends of one side of the pedestal, and the projections 3 and 3 are detachable at both ends of the other side opposite to the side. ,
The concave hooking pieces 4 are formed integrally. on the other hand,
The reinforcing bar supporting leg 5 is formed by bending a wire into a gate shape having an appropriate height and a concave portion for holding a reinforcing bar at an upper end. Also,
As shown in FIG. 2, the fitting holes 2 arranged side by side on the pedestal 21
By forming the same fitting holes 22a between the two, one or three rebar supporting legs 25 are formed so that one or three rebar supporting legs 25 can be continuously fitted. Correspondingly, the spacing between the reinforcing bars is stably maintained.

FIG. 3 is a perspective view showing a use state of the embodiment of the present invention, and FIG. 4 is a plan view showing a use state of the embodiment of the present invention. For example, as shown in FIG. 3, in the case of connecting two reinforcing bar spacing holders, after arranging the lower bar 101 of the base bar on the discarded concrete, the pedestal 1 is connected to the lower bar 1.
01 at the required position on the lower side and at the same interval.
01 is placed on the pedestal 1. In this case, the pedestal 1 is formed in accordance with the weight of the reinforcing bar and the bent state of the reinforcing bar, and the convex projecting pieces 3, 3 formed on both ends of one side of the pedestal 1 are formed on both sides of one side of another pedestal 11. Are respectively fitted to and connected to the hooking pieces 14 and 14. Next, the upper muscle 102 of the base muscle is arranged on the arranged lower muscle 101, and the reinforcing steel support legs 5, 5 are inserted into the insertion holes 2 of the pedestal 1, and another reinforcing steel support leg 1 is provided.
5 and 15 into the fitting holes 12 of the pedestal 11, respectively.
The two reinforcing bars are inserted and arranged so that the bending directions of the reinforcing bars are parallel to each other, and the upper reinforcing bar 1 is attached to the reinforcing bars 5, 5, 15, and 15.
No. 02 is placed to maintain the interval between the lower muscle 101 and the upper muscle 102 of the base muscle. In addition, as shown in FIG. 4, when supporting the reinforcing steel bars A arranged side by side, the pedestals 1 are connected obliquely, so that the pedestals are arranged side by side so that the periphery of the concrete is improved. Can be easily done.

[0009]

As described in detail above, according to the rebar spacing metal fitting for construction of the present invention, at least two or more holes are formed at regular intervals on the upper surface of the pedestal at the front, back, left, and right sides. With this arrangement, it is possible to easily support the rebar supporting legs irrespective of the direction in which the upper rebars are arranged, and to improve the work efficiency. A projecting piece on one side of the pedestal,
Since the protruding piece is detachably attached to the opposite side surface and integrally formed with each other, an appropriate number of rebar spacing holders can be easily connected, so that the rebar spacing can be stably and accurately adjusted. Thus, it is possible to obtain a practically useful reinforcing metal spacing metal fitting for construction, for example, capable of holding.
