Abstract
An integrally molded concrete molding form member is made of a fiber-reinforced plastic and formed of a long flat front plate portion, a pair of horizontal side plate portions perpendicularly extending from cross-sectional ends of the front plate portion toward its back surface, and a horizontal pair of rear plate portions perpendicularly inwardly extending from forward ends of the side plate portions opposed to the back surface of the front plate portion. Each of the front plate portion, the side plate portions and the rear plate portions is provided with a plurality of mounting holes in the same longitudinal positions at prescribed intervals to facilitate connecting front, side, back, upper and lower surfaces.
Claims6
A concrete molding form member comprising:
- a strip front plate portion being flat at least on its surface;
- a horizontal pair of strip side plate portions extending from both side ends of said front plate portion toward a back surface thereof perpendicularly to said front plate portion;
- and
- a horizontal pair of strip rear plate portions inwardly extending from rear ends of said side plate portions perpendicularly to said side plate portions, to be opposed to said back surface of said front plate portion,
- each of said front plate portion, said side plate portions and said rear plate portions being provided with a plurality of mounting holes on the same positions in relation to the longitudinal direction at prescribed intervals along the longitudinal direction, wherein
- the distance (L.sub.1) between the center of each mounting hole in said side plate portions and an edge of said front plate portion is substantially equal to the distance (L.sub.2) between the center of each mounting hole in said rear plate portions and the intersection of said side plate portions with said rear plate portions, and the width of each side plate portion is substantially equal to the width of each rear plate portion.
