It is bolted between fixed length section 13131 and transverse horizontal section 1311, transverse horizontal section 1311 and lower trisection 1312 are overall
Part, the downside of lower trisection 1312 is articulated with bed die 11 by ear mount.Interior link 132 include cross member, lower folding component and
Diagonal supporting member, the outer end of cross member is stretched out in outside the outer end of inner template transverse horizontal section, and diagonal supporting member is connected to horizontal structure
On the upside of part and inner template between the outside of trisection.Hinged seat is provided with the downside of cross member.The setting of diagonal supporting member can
Improve the stability of inner template.When the width in rail road against the wind changes, can be by laterally adjusting upper trisection and transverse horizontal
The link position of section meets use requirement, when beam is turned under the height in rail road against the wind changes or runs into middle plate, can pass through
The active segment of trisection is replaced with to meet use requirement.
Bed die 11 is perpendicularly fixed in the traverse beam 4 that horizontal cross is arranged by bolt, and the upside of traverse beam 4 sets hinged
Joint chair, supporting member 2 uses the strut of adjustable in length, and receipts, formwork erection mechanism 3 are using oil cylinder that is upper and lower, being in tilted layout.Connect outside
Connect the outside of frame 122, between the downside of the cross member of interior link 132 and traverse beam 4 support be connected with by hinged seat respectively
Component 2 and oil cylinder.When the height of rail road straight wall lower edge against the wind changes, can be by the cushioning corresponding height on the upside of bed die
Module meets use requirement.
So that operating process is simple, and large-scale is not needed to reset by hinge at each activity during use
It is standby, occupy little space, narrow underground construction requirement can be met.Supporting member 2 is used to bear suffered by template in construction process 1
Load.It is bolt connection between upper trisection and the transverse horizontal section of inner side dynamic model, is applicable to different subway station rails road against the wind
Size regulation, lower trisection and Duan Weiyi entirety of transverse horizontal, after the completion of spelling, whole inner side dynamic model is a single piece,
Need not be dismantled during use, so the molding effect quick for installation and being greatly improved concrete of template, completely can be with
Save the follow-up modification work of concrete.Receipts, the formwork erection of template, operation letter are realized by the action of HYDRAULIC CONTROL SYSTEM oil cylinder
Single quick, empirical tests only need two workmans that the receipts mould and formwork erection of template can be just fully achieved in 30 minutes, substantially reduce
The labour intensity of workman, significantly improves efficiency of construction.
As shown in Figure 1 and Figure 2, mounting system includes support 5, automatic hoisting mechanism 6 and automatic traveling mechanism 7, and support 5 is wrapped
