1. A scaffolding for temporary support of a fresh concrete floor slab, comprising means defining a main chord member disposed substantialLy horizontally and a pair of lower chord members detachably joined together at adjacent ends, the free ends of said lower chord members being respectively detachably joined to said main chord member to define a triangular structure, and at least one bracing member detachably fastened at the joint between lower chord members, the free end of said bracing being detachably joined to said main chord member, said main chord member and the lower chord members each respectively consisting of two separate members which are overlappingly joined together so as to form a single chord, the two members of each lower chord being overlappingly joined together with an intermediate element interposed therebetween, said intermediate element including opposedly wound threads at opposite ends, each member being connected to said intermediate element through a screw means such that when said intermediate element is rotated said chord members are relatively moved to change the lengths of said lower chord members.
2. A scaffolding as claimed in claim 1, wherein each of the separate chord members includes a series of openings spaced lengthwise thereof, two openings selected from each group in overlapping members being aligned so as to allow a locking means to pass through.
3. A scaffolding as claimed in claim 1, wherein two braces are used, each being joined to said main chord at points spaced apart about one-third of the length of said main chord member.
4. A scaffolding as claimed in claim 1, wherein the joints between the main chord member, the lower chord members and the bracing are each secured by a fastening means comprising a wedge means for a locking means, said wedge means being adapted to be driven by percussion blows so as to fasten said locking means.
5. A scaffolding as claimed in claim 1, wherein the triangular structure is supported between adjacent beams by means of a supporting unit, which comprises a bracket secured to said main chord member and a supporting element secured to the beam side, said bracket being detachably supported by said supporting element.
