Abstract
A formwork system for supporting forming panels to form a horizontal concrete surface. The system includes a height-adjustable support having a central upstanding member providing a vertical abutment surface and a support arm having an inclined portion extending up and away from said central upstanding member. The system also includes a beam having a transverse bar proximate an end. The transverse bar is supported by the inclined portion of the support arm so that said transverse bar moves laterally relative to the inclined portion as the support arm is moved vertically. The beam also has a foot extending from the end of the beam and abutting the abutment surface. The abutment surface opposes lateral movement of the beam relative to the upstanding member.
