Abstract
This invention pertains to a novel adjustable formwork system which can be used in the manufacture of a wide range of structurally efficient cross-sectional shaped concrete beams, columns and structures. A cast-in-place concrete beam form comprising: (a) at least two spatially oriented upper sleeves, with an upper web located on one side of the two sleeves, and extending therebetween; (b) at least two spatially oriented lower sleeves, with a lower web located on one side of the two sleeves, and extending therebetween; and (c) at least two members, each member connecting telescopically the respective upper sleeve with the respective lower sleeve, said telescoping members enabling the two upper sleeves to be raised or lowered relative to the two lower sleeves.

A cast-in-place concrete beam form comprising:
- (a) at least two spatially oriented first members, with a first planar sheet located on one side of and affixed to the two first members, and extending therebetween;
- (b) at least two spatially oriented second members, positionally matching with the respective first members, with a second planar sheet located on one side of and affixed to the two second members, and extending therebetween on the same side of the second members as the first planar sheet on the first members;
- and
- (c) at least two member connecting means, each means connecting telescopically a respective first member with a respective second member, said member connecting means enabling the first members and the first planar sheet to be extended or contracted relative to the second members and the second planar sheet.
