Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holder for holding a space between base muscles in a reinforcement work of a structure, particularly a foundation part.

[0002]

[Prior art]

 Conventionally, as a reinforcing bar spacing retainer for the base bar of the foundation part, a reinforcing bar support leg formed by bending a bar material and two fitting holes for mounting and supporting both leg parts of the reinforcing bar support leg are drilled. Although a method of using a retainer made of a pedestal made of synthetic resin is disclosed, as a usage method, after placing the lower reinforcement of the base reinforcement on the discarded concrete, the pedestal should be placed under the lower reinforcement. Place them at positions and intervals and place the inferior muscles on the pedestal. Next, arrange the upper muscle of the base muscle on the arranged lower muscle, insert the reinforcing bar support leg into the insertion hole of the pedestal already placed, place the upper bar on the reinforcing bar support leg, and It maintains the distance between the lower and upper muscles.

[0003]

[Problems to be solved by the device]

 In the conventional method described above, since the reinforcing bar supporting legs have two insertion holes, the supporting direction of the reinforcing bar is limited to one direction. Therefore, for example, the upper and lower reinforcing bars are arranged in a staggered arrangement. In the zigzag state, when placing the pedestal under the inferior muscles, the pedestal bending direction of the reinforcing bar supporting legs and The reinforcement direction becomes parallel and it becomes impossible to support the superior muscle. Further, as the base bar, a bar having a large bar diameter and a large weight may be used, and the conventional rebar spacing holder has problems such as lack of stability in strength and reliability.

[0004]

[Means for Solving the Problems]

 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 supporting leg into a fitting hole of a pedestal regardless of the direction of the reinforcing bar. An object of the present invention is to provide a reinforcing bar spacing retainer that reliably and stably maintains the spacing between reinforcing bars even if the base bar has a considerable weight.

As a means for that, it is composed of a reinforcing bar supporting leg formed by bending a bar material into a gate shape, and a pedestal made of synthetic resin having insertion holes for mounting and supporting both legs of the reinforcing bar supporting leg. In the reinforcing bar spacing holder, the fitting holes are formed at equal intervals in the front, rear, left, and right on the upper surface of the pedestal, and at least two or more holes are respectively formed on the pedestal upper surface. It is characterized in that the projecting pieces are integrally formed with detachable hooking pieces.

With the above-described structure, since the insertion holes of the reinforcing bar supporting legs are formed on the upper surface of the pedestal at equal intervals in the front, rear, left, and right, at least two or more positions are formed. It can be supported by support legs. By integrally forming a protruding piece on one side of the pedestal and a hooking piece on the other side opposite to which the protruding piece can be attached and detached, it is possible to easily connect an appropriate number of rebar spacing holders. For example, by connecting two right and left or three diagonally (see Fig. 4), it is possible to easily cope with the weight of the reinforcing bar and stably maintain the spacing between the reinforcing bars. The conventional problems are solved.

【Example】

 Hereinafter, 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, in which four corners of a synthetic resin pedestal 1 having a square upper surface from which unnecessary portions for strength are removed are located below the upper surface of the pedestal 1. A fitting hole 2 having an appropriate length is bored in the pedestal, and convex projecting pieces 3 and 3 can be attached to both ends of one side of the pedestal, and projecting pieces 3 and 3 can be attached and detached to both ends of the other side facing the side. The concave hooking pieces 4 and 4 are integrally formed. On the other hand, the reinforcing bar supporting leg 5 is formed by bending a wire rod into a gate shape having an appropriate height with a recess for holding the reinforcing bar formed at the upper end. Further, as shown in FIG. 2, by inserting similar insertion holes 22a between the insertion holes 22 arranged in parallel on the pedestal 21, one reinforcing bar supporting leg 25 or three reinforcing bar supporting legs 25 are formed. Are formed so that they can be continuously fitted, and the distance between the reinforcing bars is stably maintained according to the weight of the reinforcing bars.

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 placing the lower reinforcement 101 of the base reinforcement on the waste concrete, the pedestal 1 is placed at the required position below the lower reinforcement 101. , And the lower stir bar 101 is placed on the pedestal 1. In that case, depending on the weight of the reinforcing bar and the bending state of the reinforcing bar, the pedestal 1 is formed on both sides of one side of the pedestal 1, and the convex projecting pieces 3 and 3 are formed on both sides of one side of the pedestal 11. They are fitted and connected to the hooking pieces 14 of 14 respectively and arranged. Next, the upper muscle 102 of the base muscle is laid on the reinforced lower muscle 101, and the reinforcing bar supporting legs 5 and 5 are inserted into the fitting holes 2 of the pedestal 1 with the other reinforcing bar supporting legs 15 and 15. The two reinforcing bar support legs are inserted and inserted into the fitting holes 12, ... Of the pedestal 11 so that the bending directions of the two reinforcing bar support legs are parallel to each other, and the upper bar 102 is attached to the reinforcing bar support legs 5, 5, 15, and 15. It is placed to maintain the space between the lower muscle 101 and the upper muscle 102 of the base muscle. Further, as shown in FIG. 4, when supporting the reinforcing bars A arranged in parallel, the pedestals 1 are obliquely connected to each other so that the pedestals are arranged side by side so that the surroundings of the concrete can be improved. It can be done easily.

[Effect of device]

 As described above in detail, according to the construction reinforcing bar spacing metal fitting of the present invention, since the fitting holes of the reinforcing bar supporting legs are formed at equal intervals in the front, rear, left, and right on the upper surface of the pedestal, at least two or more positions are formed. The reinforcing bar can be easily supported by the reinforcing bar support legs regardless of the direction of the bar arrangement, and work efficiency can be improved. By integrally forming a protruding piece on one side of the pedestal and a hooking piece on the other side opposite to which the protruding piece can be attached and detached, it is possible to easily connect an appropriate number of rebar spacing holders. In addition, it is possible to obtain a practically useful construction rebar spacing metal fitting that is capable of stably and accurately maintaining the rebar spacing.
