The rib members may be monolithic or formed from plural components. Bearing plates and stabilizing plates are employed to support forces applied to the form module. ## Claims ### Claim 1 A freestanding form module for receiving flowable materials to make a wall which includes the form module, the form module comprising: at least two spaced-apart form members having opposed interior form surfaces, each form member including a wall portion and a rib portion extending from the wall portion toward another one of said form members; and at least one monolithic molded plastic tie member having opposed ends with a web member between the ends extending along a web axis, a bearing member at each end of the tie member, extending generally transverse to the web axis and embedded in the wall portion of a respective form member with the form member formed around so as to captively enclose the bearing member and each end of the tie member having a stabilizing member extending generally transverse to the web axis, spaced from the bearing member and embedded in the rib portion of a respective form member adjacent the interior form surface thereof with the form member formed around so as to captively enclose the stabilizing member. ### Claim 2 (depends on 1) The freestanding form module of claim 1 wherein the bearing member has a width extending generally perpendicular to the web axis and the stabilizing member has a width ranging between 35% and 50% of the width of the bearing member. ### Claim 3 (depends on 1) The freestanding form module of claim 1 further comprising a double-ended series of tie members extending between the form members, including end tie members at the ends of the series and remaining tie members between the end tie members, and with the form members generally parallel to each other. ### Claim 4 (depends on 2) The freestanding form module of claim 2 wherein the end tie members at the ends of the series have smaller bearing plates than the remaining tie members, and the remaining tie members having bearing members with triangular cross-sectional portions inclined toward central portions of a web member connecting the bearing members. ### Claim 5 (depends on 4) The freestanding form module of claim 4 wherein the end tie members at the ends of the series have bearing members of smaller width than the width of the bearing members of the remaining tie members. ### Claim 6 (depends on 1) The freestanding form module of claim 1 wherein the web member comprises an open matrix of web parts, each part comprising a rectangular flat plate. ### Claim 7 (depends on 1) The freestanding form module of claim 1 wherein the stabilizing member comprises a plate of rectangular cross-section, at least three edges of which are in contact with said form member. ### Claim 8 A monolithic molded plastic tie member for joining opposed wall panels together to form a freestanding form module for receiving flowable materials to form a wall which includes the form module, the tie member comprising: a web member extending along a web axis and having opposed ends; a pair of bearing members extending generally transverse to the web axis, one bearing member of the pair located at each end of the web member, the bearing member at each end of the web member including a triangular cross section portion facing toward the other end of the web member; and a pair of stabilizing members extending generally transverse to the web axis, spaced from the bearing members with the web member connected to the bearing members and the stabilizing members, the web member comprising a plurality of spaced apart flat plate portions, including triangular flat plate portions connected to the bearing members. ### Claim 9 (depends on 8) The tie member of claim 8 wherein the stabilizing member comprises a flat plate. ### Claim 10 (depends on 9) The tie member of claim 9 wherein the bearing member has a width extending generally perpendicular to the web axis and the stabilizing member has a width ranging between 35% and 50% of the width of the bearing member.
