Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
See accompanying drawing 1, the case beam external mold of a kind of hydraulic prefabricated sections rotation mode of the present utility model demoulding, comprises template part 3, falsework 4, and template part 3 and falsework 4 are bolted as entirety.Being hingedly connected with several adjustable struts 7 between the flange plate plate of falsework 4 and template part 3, by regulating strut 7 can the attitude of adjusting template part 3 flange plate, ensureing that the physical dimension of template part 3 flange plate reaches designing requirement.The beam platform position processed of bed die lower position is provided with bottom bracket 1, to prevent the out-of-flatness of beam platform position processed and a single point generation sedimentation phenomenon in beam platform position processed on the impact of formwork structure size, and for support shuttering part 3 and falsework 4.The right-hand member of bottom bracket 1 is connected by articulated mounting 2 with between template part 3, is hingedly connected with telescopic oil cylinder 6 between left end and falsework 4.Folding support rod 5 is hingedly connected with between the bottom bracket 1 of telescopic oil cylinder 6 homonymy and falsework 4.Wherein falsework 4, adjustment strut 7, telescopic oil cylinder 6, bottom bracket 1 and articulated mounting 2 become some groups along the genesis analysis of template part 3, often connect into overall structure by longitudinal connecting rod (not shown) between group.
Articulated mounting 2 comprises the screw rod of energy adjusting template part 3 upper-lower position and regulates the kidney-shaped hinge hole of horizontal level, wherein the bearing of screw rod is cemented in the end of bottom bracket 1, kidney-shaped hinge hole to be articulated and connected with the lower end of template part 3 by shipping and reselling on another market, and template part 3 can rotate along kidney-shaped hinge hole.For convenience of the demoulding, the pin joint of this articulated mounting 2 is positioned at the lower position of bed die.
In addition, between the lower position and bed die of template part 3, pull bar group is installed, for fixing between template part 3 matched moulds rear pattern plate part 3 and bed die.
In conjunction with see accompanying drawing 2 and accompanying drawing 3, the two ends of folding support rod 5 are respectively equipped with the hinged ear be hinged with falsework 4 and bottom bracket 1, middle part is provided with pin joint 10, folding support rod 5 is articulated and connected into two parts 51 by this pin joint 10, 52, near pin joint 10, two parts 51, offer respectively on 52 perforation 55, when being tending towards coaxial line after folding support rod 5 launches, two parts 51, that offers on 52 just in time aligns to perforation 55, locking pin 9 can pass this easily to perforation 55, thus restriction folding support rod 5 two parts 51, 52 relatively rotate around pin joint 10, folding support rod 5 is made to become a rigid rod, for supporting deadweight and the concreting load of cast outer mold structure.In a part 52 for folding support rod 5, being provided with the adjustable diameter and screw adjusting mechanism 53 for regulating folding support rod 5 length, by adjustment adjustable diameter and screw adjusting mechanism 53, accurately can controlling the extension elongation of telescopic oil cylinder, thus the die-closed position of accurate Control architecture part 3.Folding support rod 5 part 52 is also provided with the block 54 for limiting folding support rod 5 folding position.
The course of work is as follows:
See accompanying drawing 1-4, during matched moulds, primer fluid pressing system makes the piston rod of telescopic oil cylinder 6 stretch out, drive template part 3 around the pin joint rotary motion clockwise of articulated mounting by falsework 4, two parts 51 of folding support rod 5 simultaneously, 52 around pin joint 10 progressively stretching routine, when template part 3 moves to die-closed position, just in time two parts 51 of folding support rod 5, 52 straight line poles being tending towards coaxial line, be located at two parts 51, on 52 to perforation 55 coaxial line, insert locking pin 9, now folding support rod 5 becomes a rigid rod, coordinate with telescopic oil cylinder and be used for the deadweight of support box beam external mold and the service load of pouring concrete, this service load is delivered on beam platform position processed further by bottom bracket 1.
During the demoulding, extract locking pin 9, primer fluid pressing system makes the piston rod of telescopic oil cylinder 6 retract, drive template part 3 around the pin joint counter rotation campaign of articulated mounting by falsework 4 equally, two parts 51,52 of folding support rod 5 are around pin joint 10 progressively mutual folding movement simultaneously, when moving to positive stop 54 position, folding movement stops, and external mold is in demoulding state.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
