Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 8, the method for dismounting of Bridge High-pier overmolded template of the present invention, use retractor device to template
10 remove, and described retractor device includes sliding case 1, expansion link 2；Described expansion link 2 is extended through by the end face of sliding case 1
Other end；Described expansion link 2 is slidably matched with sliding case 1；
On described sliding case 1, two relative sides are provided with rail limiting device；Described rail limiting device includes that at least two is right
Spacing wheels 4, described spacing wheels 4 edge on the side of sliding case 1 is perpendicular to the directional spreding of expansion link 2 axis；Described limit
Position wheels 4 include runner 41 and the outer runner 42 of track in track；The outer circumference surface of runner 41 runner outer with track in described track
There is between the outer circumference surface of 42 track installation gap；
Further comprising the steps of:
1) vertical nose girder 8 is set outside template 10, retractor device is installed on vertical nose girder 8；Runner in adjustable track
Track installation gap between the outer circumference surface of the outer circumference surface of 41 runner 42 outer with track coordinates with vertical nose girder 8 so that stretch
Compression apparatus vertically nose girder 8 can slide up and down；The position of vertical nose girder 8 is regulated during vertical nose girder 8 is installed, it is ensured that
Expansion link 2 one end of retractor device can be connected with template 10 after stretching out；
2) one end of the expansion link 2 of retractor device is stretched out be connected fixing with template 10；
3) template 10 anchor ear disassembly of fastener on concrete 11 will be made in template 10；
4) controlling retractor device makes one end that expansion link 2 is connected with template 10 move towards the direction of vertical nose girder 8；Thus
Template 10 is come off from concrete 11, and makes, between template 10 and concrete 11, there is spacing；
5) control retractor device vertically nose girder 8 upwardly or downwardly to slide；Complete Bridge High-pier from rising tearing open of outrigger overmolded template
Unload.
First, described retractor device is owing to being provided with sliding case 1, and described expansion link 2 is extended through the other end by the end face of sliding case 1
Face；Described expansion link 2 is slidably matched with sliding case 1；Therefore one end of expansion link 2 can realize stretching relative to sliding case 1.
