The anchor rod tension meter in this embodiment may be applicable to various reinforcing bars, for example, the following reinforcing bars are provided in this embodiment, and the anchor rod tension meter in this embodiment may be used to test the following reinforcing bars.

The reinforcing bar is provided with: a shaft portion extending in the front-rear direction; and a head portion forged at an end of the shaft portion. The width of the upper end portion of the head portion in the left-right direction is formed to be wider than the diameter of the shaft portion, and the width of the lower end portion of the head portion in the left-right direction is formed to be narrower than the diameter of the shaft portion. An end surface parallel to the axial direction of the shaft portion is formed at an upper end portion of the head portion. The left and right side surfaces of the head portion are inclined such that the width of the head portion in the left-right direction is narrowed as going from the upper end portion to the lower end portion of the head portion. In the present invention, the upper and lower sides, the front and rear sides, and the left and right sides are set for the sake of clarity of the structure of the reinforcing bar, and do not limit the structure and the use of the reinforcing bar of the present invention. For example, the upper end portion of the head portion may be disposed to face downward or sideways. In the present invention, when a stress due to a bending tensile force and a pressing shear force acts on a reinforcing steel bar embedded in concrete, the head engages with the concrete, and therefore, the anchoring force with the concrete can be improved. In addition, in the case where the reinforcing bar is a deformed reinforcing bar in which a rib is formed on the outer peripheral surface of the shaft portion, the anchoring force with the concrete can be further improved. When the reinforcing bar of the present invention is arranged in a reinforced concrete structure, the end face of the head is disposed toward the outer surface of the structure, and the thickness of the coating on the end face of the head is a predetermined target. Further, since the thickness of the end face of the head portion is substantially equal to the thickness of the shaft portion, the thickness of the entire reinforcing bar can be reduced. This can suppress the overall thickness of the reinforcement bar, thereby reducing the weight of the structure. When the reinforcing bar of the present invention is applied to a bridge deck, the strength of the bridge deck can be improved while the weight of the bridge deck can be kept to be equal to that of a conventional bridge deck. Also, the minimum deck thickness for design can be suppressed. In addition, the reinforcing bar of the present invention has a left side surface and a right side surface formed on the head portion, and the head portion is formed in a substantially triangular shape. With this configuration, the volume of the head can be reduced as compared with a configuration in which the head is formed in a semicircular shape. Thus, when the end portion of the shaft portion is forged to form the head portion, the amount of deformation of the end portion of the shaft portion can be suppressed so as not to cut the metal fibers (forging fiber flow lines) of the head portion. Therefore, if the reinforcing bar of the present invention is used, the head can be easily formed. For the above-described reinforcing bar, it is preferable that the left side surface and the right side surface are made flat, so that the head can be easily formed. In the above-described reinforcing bar, when the plate-shaped flange portion is formed on the outer peripheral portion of the base end portion of the head portion, the head portion can be reliably engaged with the concrete, and therefore, the anchoring force between the reinforcing bar and the concrete can be increased.

Of course, the present embodiment can be used to test steel bars of other structures. The anchor rod tension meter according to the embodiment of the utility model is described below without repeated description.
