Generally large, typically eight feet by two inches by ten or sixteen or twenty-four inches, sidewalls for modular concrete forms are easily, efficiently and economically produced by cutting and by routing sheet-type polymeric material, preferably polyurethane or expanded polystyrene foam. Metal connecting members are produced in standard sizes by cutting and bending sheet steel and/or wire. The sidewalls and connecting members are transported to a building site tightly and compactly in pieces, and then flexibly assembled into precision wall forms at the site with good efficiency at any scale. The wall forms so assembled define a cavity into which reinforcing steel rod, electrical and/or communications conduit, plumbing, etc., may be entered. Concrete is poured into the cavity to create a wall having the form sidewalls as its permanent surfaces. These surfaces have and present visible, regularly-spaced sheet steel strips suitable to receive and to engage sheet metal screws for mounting anything, including more sheet-type construction materials such as wallboard or paneling, to the wall. The thickness of the concrete wall is predetermined by the dimensions of its metal sidewall-connecting members, and may easily be varied such as during the fabrication of lower to upper wall courses of a multi-story building.

[ What is claimed is:] [1.] A self-supporting form disposed as a first sidewall member in combination with a second sidewall member to define a at the time of construction a variably selectable width cavity therebetween suitable to receive flowing construction material, the combination comprising:a multi-piece transverse-connecting member, extending between the first and the second sidewall members, embedded for a one end portion of its length within the first sidewall member, and embedded for an opposite end portion of its length within the second sidewall member, the multi-piece member includinga first member portion extending from a region of the first sidewall member which is exterior to the cavity through the substantial thickness of the first sidewall member and into the cavity,a second member portion extending from a region of second sidewall member which is exterior to the cavity through substantial thickness of the second sidewall member and into cavity, anda variably selectable third member portion selectable at time of form erection and wall construction to connect the first member portion and the second member portion over a variably preselected distance to form the multi-piece transverse-connecting member, by which selectable connection of the first sidewall member and the second sidewall member are held at a variably selectably predetermined separation defining the cavity therebetween;wherein when the poured construction material is used to fill the cavity then a wall is created having the substantial thickness of the length of the multi-piece transverse-connecting member, which length of the multi-piece transverse-connecting member is variably selectable in accordance that its third member portion is variably selectable to be of a variably preselected length;wherein the wall is of variably selectable predetermined width in accordance the length of the third member portion of the multi-piece transverse-connecting member.
