Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model technology is further elaborated.It should be appreciated that specific embodiment described herein only to
The utility model is explained, is not used to limit utility model.
As shown in Figure 1,2 and 3, a kind of exterior sheathing lifting device for structure of reinforced concrete, the present embodiment with
Exemplified by cylindrical shape reinforced concrete chimney, in the cylindrical shape reinforced concrete chimney work progress, in the good barrel of colligation
Outside sets inner template and exterior sheathing respectively in bar-mat reinforcement 1, if the barrel bar-mat reinforcement 1 is by dried layer ring horizontal bar 1a and some
Vertical reinforcement 1b colligations form, and circle spacings of some vertical reinforcement 1b along chimney wall is arranged as vertical reinforcement net, to
Between inside and outside template casting concrete formed cylindrical shape reinforced concrete chimney barrel, the inside of the barrel bar-mat reinforcement 1,
Multiple exterior sheathing hoisting frames 2 are equally spacedly provided with along chimney wall inner periphery, the exterior sheathing hoisting frame 2 is arranged on vertical steel
On the inside of muscle net, and it is fixed together with vertical reinforcement net by way of colligation, is sat up straight under each exterior sheathing hoisting frame 2
Fall to have poured the concrete tube wall upper surface of shaping in next mould, lifter 3, institute are provided with the exterior sheathing hoisting frame 2
State that the upper end of exterior sheathing hoisting frame 2 is triangular in shape, the lifter 3 is lifted on the triangle knot of the upper end of exterior sheathing hoisting frame 2
Structure end, the lifter 3 are connected by wire sling 4 with corresponding exterior sheathing respectively.The exterior sheathing passes through multiple liftings
Device 3 is lifted simultaneously, and after exterior sheathing lifting in place, the exterior sheathing is fastened on barrel bar-mat reinforcement by more steel wires
1 outside, the exterior sheathing hoisting frame 2 are removed and are hung on the scaffold in chimney.
Wherein, the exterior sheathing uses 2.0mm thickness iron sheet templates, is processed into that 1.60m is high, and 1.00m is wide, totally 32 pieces, and
Its edge punches, then is linked to be four with the bolt of M5 × 15, and total length is defined by cylinder girth, by the contraction of chimney barrel during construction
