Or imply that signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore be not understood that
For the limitation to the invention.In addition, term " first ", " second " etc. are only used for describing purpose, and it is not intended that instruction
Or imply relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, " first ", " second " etc. are defined
Feature can express or implicitly include one or more this feature.In the description of the invention, unless separately
It is described, " multiple " are meant that two or more.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the invention
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of Tunnel Second Lining termination folding template, as depicted in figs. 1 and 2, including the lower mould installed in chassis end 1
Plate 2, the cope plate 3 for being articulated with lower template 2 and the adjustment mechanism 4 that cope plate 3 is opened for driving；The cope plate is with
Template is alignd towards the end face in outside when sealing mould, forms end mould plane 5；And formed between cope plate and lower template for pressing from both sides
Hold the neck 6 of waterstop.In order to ensure that burying waterstop in being arranged in neck is easily installed and position, and improve positioning accurate
Degree, generally, the cope plate and the end mould plane 5 that lower template is formed are vertical with the place plane of neck 6 when sealing mould.Need what is illustrated
It is that upper and lower template uses steel form.
Reduce splicing gap by the use of punching block as two lining chassis end moulds, therefore reduce spillage point, secondary lining concrete
It is closely knit.Buried water stop neck in being set between punching block, buries the skew of waterstop, improves the processing of construction joint in preventing
Effect, being capable of effective mortar leakage prevention.Meanwhile punching block terminal mould has smooth end mould plane, flatness is good and has larger
Intensity and toughness and stability, the ability of energy resistance to deformation is larger, is fixed when sealing mould by adjustment mechanism, the change for the end mould being effective against
Shape, two lining end moulds are smooth.
The L-type supporter 8 that above-mentioned lower template includes bottom plate body 7 and its inner side is set, the supporter 8 include vertical
Vertical beam 9 and horizontal crossbeam 10, and the free end of crossbeam 10 is towards the adjustment mechanism side；The cope plate includes top
The L-type connector 11 that plate body 7 and its lower end are set, the connector 11 includes horizontally disposed bottom girder 12 and bottom girder 12 is close
The tie-beam 13 that described adjustment mechanism one end is vertically arranged；The bottom of tie-beam 13 and the free end side of crossbeam 10 are hinged；
The upper end of the top plate body 7 is hinged with the adjustment mechanism.
Above-mentioned adjustment mechanism 4 is screw mandrel.In an optional embodiment, as shown in figure 3, adjustment mechanism 4 can include
Cylinder 14 and the screw mandrel 15 for being threaded in the both ends of cylinder 14, and the screw thread of the screw mandrel of cylinder upper and lower ends is oppositely oriented,
When screwing adjustment cylinder, the screw mandrel of upper and lower ends screws cylinder simultaneously, or screws out cylinder simultaneously.It is pointed out that screw mandrel
Free end is provided for be hinged hinge.Template is adjusted by adjustment mechanism, the labor intensity of worker is effectively reduced, than tradition
Plank sheathing saves half the time, accelerates construction speed.
The bottom of above-mentioned vertical beam 9 is be hinged with chassis end 1, convenient to adjust template position, and the scope of application is wider.In addition, this
Innovation and creation can also set a pedestal 16, and the adjustment mechanism is diagonally disposed, and its lower end is be hinged on the base, and upper end is hinged
In the cope plate.
In order to keep the stability of cope plate, above-mentioned adjustment mechanism is arranged side by side two groups.When sealing mould, stretched by adjustment mechanism
It is long, cope plate and lower template are closed, and bury waterstop in being placed in neck and be clamped, avoid it mixed in cast
Deformed when solidifying native.For the gap between template outer rim and first branch, then fixed using steel plate and/or plank.
Waterstop is buried in it is pointed out that to be clipped among upper and lower template, and reinforcing bar card is set every 30 centimetres of spacing
Son, waterstop is buried in guarantee will not deform in casting concrete.
The invention provide template, buried in can ensureing in work progress waterstop installation site accurately, ensure
Its is placed in the middle, straight, and termination concrete dense not spillage is effectively ensured, so as to improve Tunnel Second Lining concrete and waterproof quality.
Also, chassis end moulds are served as a contrast by the use of punching block as two, is easy to polish and handles, and are less likely to be damaged, not in particular cases, without
Changed, the single purchase of material, you can realization is used for multiple times.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
Protection domain within.
