REINFORCEMENT SPACER AND ITS MANUFACTURING METHOD, AND REINFORCEMENT HOLDING METHOD USING THE SAME
To provide a reinforcement spacer suitable for mass production.SOLUTION: There is provided a reinforcement spacer 3 comprising a first plate member and a second plate member that hold a welded wire mesh and keep a reinforcing bar cover thickness constant. The first plate member has an opening 4 having a substantially semicircular arc shape at the bottom, and has a notch from a position facing the bottom toward the center of the plate member. The second plate member has the opening 4 having a substantially semicircular arc shape at the bottom, and has a notch from the bottom toward the center of the plate member. At least one protrusion is provided on a side surface of the notch in the first plate member and/or on a side surface of the notch in the second plate member. A protruding region for narrowing the slit width of the opening 4 is provided on a side surface of the opening 4 in the first plate member and a side surface of the opening 4 in the second plate member. The first plate member and the second plate member are combined at the notch so as to be orthogonal to each other.SELECTED DRAWING: Figure 4
【課題】大量生産に好適な鉄筋スペーサーを提供する。【解決手段】溶接金網を保持して鉄筋かぶり厚さを一定に保つ第１板部材と第２板部材とからなる鉄筋スペーサー３であって、第１板部材は、底部が略半円弧状の開口部４を有し、底部と対向する位置から板部材の中心方向に向けて切り込み部を有し、第２板部材は、底部が略半円弧状の開口部４を有し、底部から板部材の中心方向に向けて切り込み部を有し、第１板部材における前記切り込み部の側面、及び／又は第２板部材における前記切り込み部の側面に、少なくとも１つの突起を有し、第１板部材における開口部４の側面、及び第２板部材における開口部４の側面に、開口部４のスリット幅を狭くする突出領域を有し、第１板部材と第２板部材とが互いに直交するように切り込み部で組み合わせることにより構成されることを特徴とする鉄筋スペーサー３。【選択図】図４
