PROBLEM TO BE SOLVED: To reduce the amount of materials used by placing concrete using formwork in which the end of an L frame of a predetermined length is placed at a predetermined height of an adjoining T frame as a wale, the T frame is supported by lower and upper supports, and the back of a form panel is supported by the T frame and the L frame. SOLUTION: Timbering comprises a T frame 20, an L frame 21, a lower support 22, an upper support 23, and a support fixing member 24. Both ends of the lower and upper supports 22, 23 are designed to fix the T frame 20 and the support fixing member 24 thereto by means of bolts and nuts. The support fixing member 24 is secured to foundation concrete using anchors or concrete nails. A spacer 3 is placed higher than the height of the concrete placed. After assembling of the T frame 20 using the timbering and the installation of the L frame 21 are complete, a form panel 1 is mounted. The spacer 3 is mounted to press the top of the form panel 1 toward the T frame 20. |
