Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is 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 utility model, 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.
Described side form action tank 4 and steel form carrier door frame 1 are for being articulated and connected, be convenient to side form 2 to depart from lining concrete rear flank, backform hoist cylinder 7 shrinks, can facilitate backform 5 and side form 2 simultaneously together with move down, and side form 2 and steel form carrier door frame 1 still link together, side form 2 can not be returned to lining concrete face again.
Described side form 2 and backform 5 are three-dimensional space curved surface structure, and side form 2 and backform 5 are split-type design.Described three-dimensional space curved surface structure is Space Double curved-surface structure.
Described side form 2 with longitudinal rotating shaft 8 for rotating in axle center, steel form carrier is in any position of bend loss, side form 2 all can to turn to the inside the demoulding for axle center in longitudinal rotating shaft 8, can not by the restriction of three-D space structure shape of template and template effect of weight, and template can not be distorted and be out of shape during the demoulding, after steel form carrier is in place, side form installation in position can be made with longitudinal rotating shaft 8 to design attitude for axle center laterally rotates.
A kind of three-dimensional space curved surface steel mould trolley release method, comprises the following steps:
One, as shown in Figure 4, the top that dismounting side form 2 connects with steel form carrier door frame 1 and middle part side form screw mandrel 3, side form screw mandrel 3 is articulated form, and screw mandrel removes the longitudinal rotating shaft 8 being constrained to top and the bottom side form action tank 4 of rear side mould 2.After this, the one-sided side form action tank 4 of side form action tank 4(shunk bottom side form 2 arranges 3 ~ 4 altogether, and can synchronization action), side form 2 can be made with longitudinal rotating shaft 8 for axle center turns to the inside, the side form 2 of steel form carrier door frame 1 both sides is impelled to depart from the concrete side of lining cutting, this state side form 2 top departs from concrete surface apart from less, departs from concrete surface apart from larger bottom side form 2.
Two, as shown in Figure 5, the backform jack 6 of the support backform 5 at steel form carrier door frame 1 top is shunk.
Three, as shown in Figure 5, shrink the backform hoist cylinder 7 at steel form carrier door frame 1 top, the stroke of oil cylinder is advisable to meet backform disengaging top concrete face 15 ~ 20cm, after oil cylinder shrinks backform 5 and side form 2 under gravity simultaneously together with move down, impel the side form 2 of steel form carrier backform 5 and both sides to depart from the concrete surface of lining cutting.
Three-dimensional space curved surface steel mould trolley is realized in the bend loss demoulding by above method.
