Abstract

PROBLEM TO BE SOLVED: To secure the covering depth of a reinforcing mild-steel bar by utilizing a separator for fixing a concrete form, and using a plurality of holding tools each at suitable intervals. SOLUTION: A reinforcing mild-steel bar is threaded through a specific hole so that the bar lies in the position specified by the design and hitched at and fastened to a separator which is for fixing an inner and an outer concrete form. The part of a separator hook 13 for fixing forms 1, 1 is hitched at a bar hitching hole 12 in a holding tool 5 for the covering depth of the bar, and thereby the bar is fixed to the specified position. Such holding tools are used at suitable intervals so that the covering depth of the bar is secured. This eliminates necessity for use of conventional width stopping iron piece and spacers, to quicken the execution of works, and even unskilled workman can make sure operations. Because there is no object to constitute an obstacle, good concrete flow is generated when concrete is to be placed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar cover thickness retention.

[0002]

2. Description of the Related Art It is extremely important to secure a cover thickness of a reinforcing bar in a reinforced concrete structure in order to secure the strength of a building and prevent corrosion of the reinforcing bar. Conventionally, as a method of securing the cover thickness of the reinforcing bars, donut-shaped spacers or other spacers are attached to the vertical bars and the horizontal bars to secure the cover thickness.

[0003]

However, since many donut-shaped spacers are attached, it is troublesome and costly, and there are many problems such as the flow of concrete is impaired when pouring concrete and junkers are formed. It was

The object of the present invention is to solve the above-mentioned problems, the installation is easy, the flow of concrete is good without labor, and the cover thickness can be easily maintained. It is to provide the ingredients.

[0005]

A reinforcing bar cover thickness retainer of the present invention for solving the above-mentioned problems is obtained by passing a reinforcing bar through a deformed hole so that the reinforcing bar is in a position as designed, and forming the inner and outer molds. The structure is characterized in that it is hung and fixed on a separator for fixing the frame.

[0006]

Further, according to the above structure, a separator for fixing the mold is used, and a plurality of holders are used at appropriate intervals to fix the reinforcing bars and improve the flow of concrete. Secure the cover thickness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a reinforcing bar cover thickness retainer of the present invention will be described below with reference to the drawings. FIG. 1 shows a reinforcing bar cover thickness retainer of the present invention. FIG. 2 is a plan view showing a state in which the reinforcing bar cover thickness retainer of the present invention is attached. Reinforcing bar cover thickness retainer (hereinafter retainer) 5. Reinforcing bar hole 12. 5. A separator for fixing the formwork (1.1) through the 6. On the separator 13. Reinforcing bar is fixed by hanging the part. The cover thickness of the reinforcing bar can be secured by using this holder at appropriate intervals.

[0008]

As is clear from the above description, when the holder of the present invention is used, the width stop bar 1 which has been conventionally used.
0. And spacer 11. Is unnecessary, construction is quick,
Even unskilled workers can perform reliable work and there are few obstacles, so when pouring concrete, the flow of concrete is good and it is difficult to make junkers. In addition, the transportation cost is low, and it is possible to obtain excellent effects such as improvement of earthquake resistance, improvement of work efficiency, and reduction in construction as a whole.
