Description

  The present invention provides a bar arrangement that is used to arrange a hoop bar or a horizontal bar for each set dimension (exactly) in a vertical bar that has been arranged when constructing a structure such as a column, a column shape, or a wall. It relates to a jig.

  When building a pillar of a concrete structure, a hoop bar (horizontal bar) with a predetermined gap between the upper and lower ends of the vertical bars (vertical bars) with a predetermined gap on the left and right. ).

  When arranging the hoop muscles as described above, a hoop muscle width stopper is used so that the upper and lower hoop muscles maintain a constant interval (Patent Document 1).

Design Registration No. 844019

  By the way, the hoop line width stopper of patent document 1 is between the string material, the inverted U-shaped hanging hook provided at the upper end of the string material, and the upper end portion to the lower end of the string material. It is composed of U-shaped hoop reinforcement fitting support hooks arranged at regular intervals, and the above-mentioned string material, hanging hook and support hook are molded products integrally molded with synthetic resin. is there.

  According to such a configuration, an expensive mold is used for the synthetic resin molded product, so that the unit price is greatly increased, and the pitch between the support hooks is increased depending on the diameter of the pillars to be built, or There is also a problem that a plurality of molds corresponding to the pitch are required because the size is reduced.

  In particular, since the string material is made of a synthetic resin material, if the total weight of the hoop muscles supported by the respective support hooks becomes large, the total weight cannot be endured, and the length of the string material is restricted.

  For this reason, the problem that a plurality of hoop muscle width stoppers must be added up and down is used.

  As described above, according to the bar arrangement jig of the present invention, the hook is fixed to the upper end of the long metal body by welding to attach the hanging hook from the upper end portion of the long body to the lower end. Since the hooks are fixed by welding at positions that are equal to the bar arrangement pitch and the reinforcing bar supporting hooks are provided, the hanging hooks are attached to the top hoop iron and horizontal reinforcing bars that are supported by the vertical reinforcing bars via the binding wires. The long body is hung down by hanging, and the hoop and horizontal rebars can be dropped and supported on the reinforcing bar support hook, and the long body, wire, wire, and strap are made of metal, so the bars are arranged. Even if the total weight of the reinforcing bars is large, it can be supported in a stable state without being sheared, and it is not restricted by the length of the long body, and eliminates various problems such as an integrally molded product made of synthetic resin. be able to.

  In addition, even in a bar arrangement jig that does not have a hanging hook at the upper end of the long body, since the wire is used for the long body, the upper end of the long body is placed on the hook. In addition, by engaging the hanging metal fitting with the bent hook, it is possible to hang down the long body very easily by hooking it on the hoop or horizontal reinforcing bar.

  Furthermore, a long hole is provided with a through hole, and a hook hook or a reinforcing bar support hook engaging portion is inserted into the through hole so as to be engaged. Since a method that makes the engaging claws of the reinforcing bar support hooks engage and a method that makes the hanging hooks and engaging hooks of the reinforcing bar support hooks engage in the notches of the long body, Unlike the system, it can be assembled and used very easily on site.

  Also, the projecting shaft of a hanging hook or a reinforcing bar support hook is passed through each through-hole of the long body, and the projecting end of the projecting shaft is fixed (attached) by retaining processing, for example, deformation or caulking work by hitting. Can do.

  Of course, even if it is a type that does not have a hanging hook at the upper end of the long body, it is possible to make a hoop or horizontal rebar by using a hanging bracket system such as bending the upper end of the long body into a hook shape. It is also possible to hang down the long body by hooking it on.

  In addition, the end of the horizontal part of the hook and the hook mounting part are fixed by welding at positions spaced from the upper end part of the long body to the lower end arrangement pitch, and the hook lacking part is attached to the long body. Since the reinforcing part is fixed by welding and the reinforcing bar support hook is provided, the reinforcing bar can be dropped and supported on each reinforcing bar support hook of the elongated body. Even if the total weight of the reinforcing bar is large, there is no shearing of the metal long body, it can be supported in a stable state, and a reinforcing bar support hook can be provided without being restricted by the length of the long body .

  Furthermore, since the hanging part is provided at the upper end of the long body, the long body can be hung down by hooking the hanging part on the hoop or horizontal reinforcing bar.
