Abstract
The invention relates to a three-dimensional space curved face steel-mould trolley demoulding anti-interference device and method. Through longitudinal rotary shafts arranged on the tops of side moulds and the lower portions of a top mould, side mould action oil cylinders at the bottoms of the side moulds contract, the side moulds are rotated towards the inner side with the longitudinal rotary shafts as the axis, and demoulding of a three-dimensional space curved face steel-mould trolley at the bend section can be achieved successfully. The problem that as the boundaries of the top mould and the side moulds are space folding lines due to limitation of the three-dimensional space structural shape, the side moulds cannot contract transversely for demoulding through conventional arrangement is solved. The demoulding quality is high, templates will not twist or deform, the templates will not intervene in lined concrete, and construction safety is guaranteed.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
See Fig. 1-3, a kind of three-dimensional space curved surface steel mould trolley demoulding anti-interference device, comprises longitudinal rotating shaft 8, and longitudinal rotating shaft 8 is positioned at side form 2 top and backform 5 bottom, is connected with side form 2 and backform 5 by connector 9.Needs illustrate, adopt structure of the present invention, the position of longitudinal rotating shaft 8 should ensure side form 2 with longitudinal rotating shaft 8 for axis rotation, and when ensureing that side form 2 rotates again, side form 2 top does not contact with the concrete side of lining cutting, and namely lining concrete face is left at side form 2 top.Described longitudinal rotating shaft 8 is along steel form carrier longitudinally elongated layout.
Described side form 2 is connected by multiple side form screw mandrel 3 and side form action tank 4 with steel form carrier door frame 1.Described side form screw mandrel 3 is distributed in top and the middle part of side form, is articulated and connected with steel form carrier door frame 1, screw mandrel adjustable length and be convenient to installation and removal, facilitates the template demoulding and installation in position.
Described backform 5 is connected by multiple backform hoist cylinder 7 with steel form carrier door frame 1, and is provided with multiple backform jack 6.Described backform hoist cylinder 7 and backform jack 6 are distributed in both sides, steel form carrier door frame 1 top, and the stroke of oil cylinder adapts to template demoulding height.
