A lightweight concrete nailer form preferably includes a semi-tubular member and a plurality of cross members. The semi-tubular member includes a bottom wall, a first sidewall, a second sidewall, a first upper flange and a second upper flange. A height of the first and second sidewalls may also increase over a length of the semi-tubular member to form a tapered semi-tubular member. A plurality of openings are preferably formed through the bottom wall and the first side wall for the flow of lightweight concrete. The cross member preferably includes a bottom flange, an upright member and a top flange. An opening is formed through the upright member for the flow of lightweight concrete. The plurality of cross members fit inside the semi-tubular member. The semi-tubular member may be stacked with a second semi-tubular member. A cover plate may be attached to a top of the semi-tubular member.

Lightweight concrete nailer form

A metal nailer with adjustable curvature preferably includes an upper member and a lower member. The upper and lower members start as strips of material. A plurality of first openings are formed adjacent a first edge of each strip. A plurality of second openings are formed adjacent a second edge of each strip. A plurality of fastener openings are formed in the lower strip and a plurality of fastener clearance openings in the upper strip. An upward bent fold is formed in a center of each of the plurality of first and second openings. First and second edges of the strips are bent to form a U-shape. The upper member is inserted into the lower member. The upper and lower members are attached to each other with a plurality of fasteners. The metal nailer with adjustable curvature may be bent in horizontal and/or vertical planes.
