High-altitude supporting mold of structureless floor slab

Abstract

The invention provides a high-altitude supporting mold of a structureless floor slab. The structure of the high-altitude supporting mold is characterized in that a temporary platform is erected on a horizontal structure at the periphery of the structureless floor slab area and comprises main steel beams, secondary steel beams and scaffold boards; the main steel beams are erected on the floor slab of the base structure of a frame body of the horizontal structure at the periphery of the structureless floor slab area; the two side surfaces of the main steel beam are fixed with structure beam plates of a construction layer; the secondary steel beams are erected on the main steel beams and are fixedly connected with the main steel beams; and the scaffold boards are laid on the secondary steel beams to form the temporary platform. The high-altitude supporting mold provided by the invention has the effects that the horizontal structure at the periphery is reasonably utilized for erecting the temporary platform, the applicability to the multilayered structureless floor slabs at the lower part and the erecting height is more than 20m; the erecting height of the supporting frame body is high, the construction risk is large and the construction cost is increased due to long-time leasing; and the temporary platform is erected at the overhead part of the floor slab, so that the erecting height of the supporting frame body is reduced; and the elevated supporting mold is converted into the common beam-plate supporting mold, so that the used amount of erecting materials is reduced by 75%.

Description

technical field [0001] The invention relates to a high-altitude support formwork for a structureless floor slab. Background technique [0002] During the construction of the building structure, the beam slab on the construction floor uses the support frame body 5 as a temporary support system before the concrete of the beam slab reaches its strength. The construction requirements of structural beam and slab 4, such as figure 1 shown. [0003] Such as figure 2 As shown, when there are multiple layers of non-structural floors under the structural beam-slab 4 area of ​​the construction layer in the structure, the conventional method is to use super-elevated formwork for construction, and the support frame body 5 is based on the lower structural floor. , when the height of the elevated formwork supporting frame body 5 is greater than 20m, the amount of erecting material used for the supporting frame body 5 increases, the construction difficulty increases, the safety factor d...
