Abstract

The utility model relates to an overlapped slab form support frame which comprises a triangular truss consisting of an upper chord, an ejector rod and braces. The overlapped slab form support frame is characterized in that the upper chord is formed by overlapping and connecting two inverted U-shaped steels at the middle section of the upper chord; each brace is formed by overlapping and connecting two flat steels at the middle section of the brace; the upper end of the ejector rod is connected with the middle part of the upper chord and the lower end of the ejector rod is connected with the braces. The upper chord of the overlapped slab form support frame adopts the inverted U-shaped thin-wall cold-formed steels with large section sizes; bending strength inside an inter-section plane of the overlapped slab form support frame is high; the overlapped slab form support frame can bear a large centralized load between sections, so that wooden battens are more flexibly arranged; in addition, the plane of the upper chord has high external rigidity; the requirement for a lateral stable fulcrum of the support frame is lowered; integral stability of the support frame is greatly improved.
