簡易型枠及び法枠の施工方法

Simple form and execution method for slope frame

Abstract

(57)【要約】 【課題】 少ない材料で構成される簡易型枠、及び容易 に設置でき、所定の法枠断面を確保できる法枠の施工方 法を提供すること。 【解決手段】 簡易型枠は、コの字形の鋼材と、波形の 線材と、からなり、コの字形鋼材を、投影するとコの字が 重なるように間隔を置いて並べ、前記コの字形鋼材を波 形線材で連結することを特徴とするものである。法枠の 施工方法は、上記の簡易型枠を、長手方向が第1の方向か つコの字形鋼材の中辺が法面側となるように、間隔を置 いて設置し、第2の方向を向いた第2棒材を、交差する第 1簡易型枠の波形線材で支持するように設置する。そし て、第1棒材を前記第2棒材で支持するように、前記第1 簡易型枠の略中央に設置し、上記第2棒材と第1棒材の 設置を所定の数だけ繰り返し、本発明の簡易型枠を、前記 第2棒材の位置に設置し、簡易型枠にモルタル又はコン クリートを吹付けるものである。
PROBLEM TO BE SOLVED: To provide a simple form constituted of a small number of materials and a construction method for a slope frame capable of being installed easily and ensuring a predetermined slope frame cross section. SOLUTION: This simple form consists of a U-shaped steel member and a corrugated wire, U-shaped steel members are arranged at an interval so that U shapes are overlapped when projected, and the U-shaped steel members are mutually connected by the corrugated wire. In the work execution method for slope frame, the simple forms are installed at an interval so that the longitudinal direction becomes a first direction and a middle side of the U-shaped steel member becomes a face-of-slope side, and a second bar member facing a second direction is supported by crossing corrugated wires of a first simple form. A first bar member is installed at substantially center of the first simple form so as to support it by the second bar member, the installation of the second bar member and the first bar member is repeated by the predetermined number, the simple form is installed at the position of the second bar member, and mortar or concrete is sprayed on the simple form.
