Title: Universal column or beam concreting formwork - comprising standard form elements regardless of width, varied by clamps and fixtures
Inventor: HUEBNER WALTER
IPC: E04G13/02
Filed: 1975-11-27
Abstract: The formwork, for concreting columns, posts, beams or girders, is designed to be flexible and variable, so that it can be quickly used for production of such units regardless of dimensions, without special planning or cutting to size. Standard trade form elements are used, with widths independent of the required reference basis, with clamping and fixing elements as necessary for variable sheathing, without changing the elements themselves. The clamping and fixing elements may incorporate hinges, permitting the construction of basic forms at more than 90 deg. angles. They may be U-sectioned, and extensible in length. The principle is also applicable to round forms. Strutting units may be incorporated, for increased stability, these too being variable by means of rows of holes and bolts.
