The timber beam column formwork system is a combined type of formwork that uses steel and wood together. The components of this system include 18-millimeter plywood, 200-by-80-millimeter H20 timber beams, channel steel walers, flange clamps, angle tie brackets, connecting plates, lifting hooks, wedges, and other parts.By modifying the size of the formwork section area, the adjustable column formwork allows concrete casting of square or rectangular columns within a given range. The correction is accomplished by shifting the walers' relative positions. The walers of adjustable column formwork, which may cast concrete for square or rectangular columns with side lengths ranging from 200 to 1400 mm, come in three different specifications.
