The invention comprises a connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.

A concrete form includes a first sidewall and a second sidewall positioned in parallel and spaced relation to each other and a cross tie having opposed first and second ends, where at least the first sidewall is a removable sidewall removably secured to the first end of the cross tie. The second sidewall is removably secured to the second end of the cross tie and may be a removable sidewall or a non-removable sidewall. The concrete form also includes a spacer positioned between the first sidewall and the first end of the cross tie. The spacer may be removable along with the first sidewall. Concrete forming assemblies and methods may incorporate concrete forms as described herein.

The plastic form is made from a plastic material mixed with a number of glass fiber particles, is formed by melting the plastic material and particles, and then by injection molding through distributing the melted material into a mold via a grid forming machine. The plastic form has a first piece, a second piece, an intermediate layer with a number of connection ribs and through channels. The through channel leads to light weight for convenient transportation and installation. The smooth first and second pieces lead to convenient stripping and well-finished concrete surfaces. The connection ribs enhance the plastic form's strength in withstanding deformation, contributing to the plastic form's reusability and environmental friendliness.

A formwork truncation screw rod includes a self-tapping screw and at least one fixing part. The self-tapping screw includes a spiral portion around the outside of the self-tapping screw, a driving end, a tapping end at an opposite end of the driving end, a diameter shrinkage portion between the tapping end and the spiral portion, and an extending portion between the tapping end and the diameter shrinkage portion. After the tapping end is fixed to the fixing part, the diameter shrinkage portion is made to protrude from the fixing part. Then, the diameter shrinkage portion is broken to remove the tapping end, thereby preventing the tapping end from damaging to the user. In this invention, the impact to the formworks between which concrete is grouted may be decreased and the formwork support capability may be increased, and few component is needed for quick assembly and simplified process.
