Abstract

PURPOSE:To simplify the extent of assembly for a mesh formwork bent at a corner part as well as to make a straight line and accuracy so accurate enough by connecting a corner top end support member of L-shaped, T-shaped forms to a straight top end support member with a joiner. CONSTITUTION:In a corner top end support member B, an angled outer ruler member 16 and an inner ruler member 17 are connected to each other with an interval holding member 18, and a joiner 21 is installed projectingly from each end of these outer and inner ruler members 16, 17, forming this corner top end support member B. Next, in a straight top end support member A, A pair of angled straight ruler members 23 are set up parallelly, and connected together with the interval holding member 18 and a connecting member 24, forming this member A. Then, an interval between adjacent corner top end support members B and B is connected by the straight top end support member A. With this constitution, a foundation formwork with a corner part can be easily assembled, and since a mesh plate upper end is supportable upright, longitudinal accuracy of the foundation is thus improvable.
