Description

  The present invention relates to a transverse bar holder used for binding horizontal bars to a plurality of standing vertical bars when assembling reinforcing bars.

There are various procedures for assembling the reinforcing bars. For example, a plurality of vertical bars are installed at predetermined positions, the horizontal bars are crossed so as to cross these vertical bars, and the intersection of the vertical bars and the horizontal bars. It is common to bind these with a binding tool. In this case, when long transverse muscles are used, it is difficult for one worker to bind the longitudinal muscles while supporting the transverse muscles, and two or more workers place the transverse muscles at a predetermined position of the longitudinal muscles. Thus, the longitudinal and transverse muscles must be tied together.
Thus, various techniques for saving labor and binding the vertical and horizontal stripes at an accurate position have been disclosed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

  The technique described in Patent Document 1 is a technique related to a reinforcing bar assembly jig for use in reinforcing bar assembly in a high-structure reinforcement method. Continuously setting axial reinforcing bars and belt reinforcing bars at designed reinforcing bar intervals. In this case, rebar assembly is performed. The jig for assembling reinforcing bars includes a plurality of reinforcing bar holding parts that hold a plurality of reinforcing bars one by one, and an interval adjusting part that adjusts the interval between the plurality of reinforcing bar holding parts. The reinforcing bar holding part is fixed by tightening a bolt through an axial reinforcing bar through a pipe-shaped holding metal part with a part cut away.

  The technique described in Patent Document 2 relates to a bar arrangement jig for the purpose of performing stable bar arrangement with no dimensional variation even when the bar arrangement is performed by a small number of workers who do not require skill. Technology. This reinforcing bar jig has a support column erected upward from one side of the support base, and the support column is provided with a large number of arms for temporarily holding reinforcing bars in the horizontal direction at predetermined intervals. .

  The technique described in Patent Document 3 is a technique related to a reinforcing bar fixing jig for the purpose of fixing intersecting reinforcing bars and holding them in a desired assembled state. The reinforcing bar fixing jig includes a first clamp member and a second clamp member for clamping the main reinforcing bar. The first clamp member is made of a synthetic resin material that has elasticity and can obtain the mechanical strength necessary for fixing, and is arranged along the longitudinal direction so that the main muscle can be forcibly fitted and clamped. It is formed as a C-shaped sleeve-like member having a slit. The second clamp member is formed integrally with the first clamp member, has substantially the same configuration as the first clamp member, and clamps the main muscle that intersects the main muscle to be clamped by the first clamp member. .

  However, the techniques described in Patent Document 1 and Patent Document 2 described above have a large-scale structure, which is not only troublesome to install and remove, but also has a low degree of freedom, so the mounting position can be changed on site. When forced, they could not respond appropriately.

  Moreover, although the technique described in patent document 3 mentioned above is a simple structure, there existed a problem that a clamp member had to be produced according to the diameter of the reinforcing bar to attach, and lacked versatility. In addition, since it is assumed that the reinforcing bars are clamped and embedded in the concrete, a large amount of fixing jigs are required, which increases the manufacturing cost of the building.

  The present invention has been proposed in view of the above-described circumstances, and can be attached to an arbitrary position of the vertical stripe, can easily hold the horizontal stripe, and is simple after the binding of the vertical stripe and the horizontal stripe is finished.

  Moreover, in the transverse bar holder of the present invention, the fixing part is an insertion hole positioned outside the other side of the outer peripheral surface of the vertical bar, and a member inserted into the insertion hole, the outer peripheral part of which is the outer periphery of the vertical bar By sticking to the other side of the surface, it is possible to configure the horizontal stripe holder from a fixing piece for fixing the horizontal stripe holder to the vertical stripe. In this case, the fixing portion is provided in the extension portion, but the fixing portion can be provided in another location.

  Further, in the transverse muscle holder of the present invention, the transverse muscle support portion preferably includes a transverse muscle placement surface that is inclined upward from the bridge portion side toward the distal end portion, and further, the transverse muscle is placed on the transverse muscle placement surface. It is possible to provide a holding recess for holding.

  According to the transverse muscle holder of the present invention, attachment to and removal from the longitudinal muscle is easy, and further, it is possible to arrange the transverse muscle at an appropriate position of the longitudinal muscle without requiring many workers. In addition, since the transverse bar holder of the present invention has a simple structure, it is not only easy to manufacture but also can reduce manufacturing costs.
