Description

The present invention relates to a rod support for reinforcing bars that is detachably attached to a rod body that is fixed to a reinforcing bar and serves as a reference when photographing a field record.

At construction sites for reinforcing bars for concrete structures, it is necessary for administrative agencies to take photographs of the installation status of the reinforcing bars as a record of the site in order for administrative agencies to confirm whether the reinforcing bars have been installed in accordance with regulations. , is legally required. It is necessary to record with photographs that the reinforcing bars are arranged at predetermined intervals, and a reinforcement rod (leveling rod) is used when taking photographs to record the site. The reinforcing rod is formed into an elongated shape and has a scale engraved along its length, and when fixed to the reinforcing bar, it serves as a mark (reference) for photographing.

The reinforcing rods are generally fixed by a worker by holding them and fixing them to the reinforcing bars during photographing, and this work requires a plurality of workers. This is a complicated process, and improvements have long been sought. In order to save labor and improve the efficiency of this photographing work, several reinforcing bar rod supports (hereinafter also referred to as "supports") for fixing or holding the reinforcement rods have been proposed. There is.

An example of a conventional support device is a marker body that is attached to a reinforcing bar and used as a landmark when taking photographs to record the scene.The front side of the marker body has a colored identification part. A device that can be provided is known (for example, see Patent Document 1). Further, on the back side of the marker main body of this brace, a holding part is provided to removably hold the reinforcing bar. This holding part is provided with a plurality of holding arms arranged in parallel in the vertical direction at intervals that allow them to be engaged with nodes of the reinforcing bars.

Another example of this device is to attach a slide fitting on which a permanent magnet is attached to the rod body so that it can slide freely in the longitudinal direction of the rod body, thereby utilizing the attraction force of the permanent magnet. Also known is a method in which a rod body is firmly fixed to a reinforcing bar (for example, see Patent Document 2).

Japanese Patent Application Publication No. 2010-008347 Utility Model Publication No. 63-031321

The brace described in Patent Document 1 has a structure of a clamping portion and its clamping arm, and has a complicated structure, and may also be complicated to attach to or detach from the reinforcement rod body at a construction site. The brace described in Patent Document 2 has a structure in which the rod body is fixed to the reinforcing steel by the magnetic force (attractive force) of a permanent magnet. However, it is necessary to increase the attracting force, and due to the magnitude of the magnetic force, it is difficult to use it in the field. Adjustment of the fixing position may become complicated.

In addition, at construction sites where reinforcing bars are used, reinforcing bars of various diameters are placed together as horizontal and vertical reinforcements, and the horizontal reinforcements are placed in front (outside) of the vertical reinforcements, and vice versa. In some cases, not only the reinforcing bars have different diameters, but also the front-back (inside-outside) relationship of the horizontal or vertical bars is changed as appropriate, resulting in a mixture of these. Under these circumstances, these conventional supports were often unable to adapt to the various diameters of reinforcing bars present at construction sites.

As such, it can be said that there is room for improvement in these conventional supports in terms of structural simplification and ease of attachment to reinforcing bars of various warps at construction sites.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to have a simple structure that can adaptively accommodate and stably engage reinforcing bars of various diameters existing at construction sites.
