Description

Technical Field

[0001] The utility model relates to the technical field of cantilever slab construction, in particular to a frame support platform for a cantilever slab. Background Technique

[0002] A cantilever slab refers to a plate-like member supported only on one side, generally a reinforced concrete structure. Therefore, formwork support is required for the cantilever slab. The frame support platform is to build a full hall scaffold under the cantilever slab and use the full hall scaffold for formwork support of the cantilever slab. A patent application with the publication number CN117868449A discloses a similar frame support platform. The support platform uses the outwardly extended fixed vertical rod part as the skeleton, and lays wooden boards or bamboo stringer boards above the fixed vertical rod part to form the platform main body; the fixed vertical rod part left on the floor slab is fixed through vertical rod positioning steel bars; the outer end of the fixed vertical rod exposed outside is fixed through steel wire ropes or inclined pull rods. The steel wire ropes or inclined pull rods and the vertical rod positioning steel bars also horizontally limit the fixed vertical rods. In this technical solution, it is difficult to adjust the length of the steel wire ropes or inclined pull rods controllably, and it cannot ensure that the outer end of the fixed vertical rod is in a horizontal state, which is not conducive to the erection of wooden boards or bamboo stringer boards.
