Description

[Detailed description of the invention]

[0001]

[Industrial application] This invention is, for example, a concrete
The present invention relates to a reinforcing bar support for construction used to reliably maintain the spacing between the frame and the frame of the main reinforcing bars, walls, and beams in building a structural structure, that is, the cover thickness of the concrete.

[0002]

2. Description of the Related Art Heretofore, as a reinforcing bar support for this kind of application and purpose, a hook in one direction is simply bent with respect to the other end of a round bar-shaped main body having an attachment portion to the formwork side at one end. There has been put into practical use one that hooks a column main reinforcement or the like inside the hook portion and draws it toward the formwork to maintain a predetermined interval.

[0003]

[Problems to be Solved by the Invention] In the above conventional method,
This function simply pulls the column main reinforcement to the formwork side, so when the column main reinforcement is positioned close to the formwork on the contrary, the exact cover thickness of the concrete can be maintained. However, the quality and accuracy of the structure were poor, and there was a case where trouble occurred.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object the purpose of being able to push and pull a reinforcing bar with a single reinforcing bar support, to provide excellent workability, and to provide accurate work. The cover thickness of the concrete can be secured, and the quality and
It is an object of the present invention to provide a reinforcing steel support for building from which a highly accurate concrete structure can be obtained.

[0005] As a means therefor, a reinforcing bar hook formed by bending a hook portion for connecting and pushing into a Z shape is connected to the other end portion of a round bar-shaped main body having an attachment portion to the mold side at one end portion. The stop is provided integrally.

With the above structure, when the space between the form and the reinforcing bar is narrow, the reinforcing bar is pushed by the pushing hook portion of the reinforcing bar retaining portion, and when it is wide, the reinforcing bar is pulled by the pulling hook portion. The object of the present invention is to solve the above-mentioned conventional problems, such as simple, easy and reliable use of a tool, securing a cover thickness of the concrete, and obtaining a concrete structure with high quality and high accuracy.

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. 1
Is a round bar-shaped main body having an attachment part 2 to a formwork with a male screw at one end, and a reinforcing bar hook formed by bending a hook part 3.4 for connection and pushing and pulling into a Z shape at the other end. The part 5 is provided integrally.

FIG. 2 is a plan view of a use example according to an embodiment of the present invention. When the position of the main column B arranged in the form A is close to the column form A (A), the fitting C is appropriately screwed into one end of the main body 1 of the reinforcing bar support. Then, the hook 3 for pushing in the reinforcing bar hooking portion 5 at the other end is hooked to the column main bar B and pushed to a predetermined position to fix the fixture C on the slab form D by nailing. . On the other hand, if the main column B is too far from the column form A (b), the hook 4 for pulling the reinforcing bar hooking portion 5 at the other end is hooked and pulled to a predetermined position. Then, the fixture C is nailed and fixed on the slab form D.

Next, another embodiment of the present invention will be described with reference to the drawings. FIG. 3 shows an example in which one end of a main body 11 of a reinforcing bar support is flattened to form an attachment portion 12 to a formwork, and a hole 12a for nailing is directly formed in that portion. . In the case of this embodiment, the column main reinforcement is appropriately pressed against the column formwork with the reinforcing bar retaining portion 15 at the other end as required, or pulled, and the flat main mounting portion 12 is used. It can be directly nailed on the slab formwork. Therefore, there is no need for a separate fixture as described above.

[0010]

As explained in detail above, according to the reinforcing bar support of the present invention, the Z-shaped reinforcing bar hooking portion formed integrally with the other end of the main body allows the column main reinforcing bar and the formwork to be connected. The spacing, that is, the cover thickness of the concrete, can be accurately and securely held and attached by a simple and easy operation of pushing or pulling one of the main bodies, and the pressing force can be applied to one reinforcing bar support. With the two functions of pulling, it is economically advantageous, shortens the working time, and can be expected to have a remarkable effect on improving the quality and accuracy of concrete structures. A reinforcing bar support can be obtained.
