Abstract

A free standing form module for receiving flowable materials includes a pair of form members, preferably made of styrofoam, joined together by molded plastic rib members. 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

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 of said form members;

a series of tie members extending between the form members, the tie members comprising a pair of end parts, with a middle part between the end parts, the end parts and the middle part joined together in serial succession;

each 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 a respective form 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 a respective form member adjacent the interior form surface thereof; and

the tie members at the ends of the series have smaller bearing plates than the remaining tie members.

2. The freestanding form module of claim 1 wherein the bearing member comprises a plate.

3. The freestanding form module of claim 2 wherein the stabilizing member comprises a channel with an opening facing toward another of said form members and a stabilizing surface opposite the opening.

4. The freestanding form module of claim 3 wherein the middle part comprises a plate with enlarged ends received in the channel opening.

5. The freestanding form module of claim 4 wherein the channel opening is located adjacent the interior form surface.
