Central trench template-setup is in the lower section of trestle, according to different duty requirements, the position of central trench template moves forward along with the needs that carry out of construction, but trestle is completely covered on the top of central trench template, mobile difficulty, causes that construction motility reduces, and operability is relatively low, and central trench template is steel part structure, Mobility Center ditch template needs to expend substantial amounts of manpower and materials.
Traditional central trench template is after casting central trench molding, and form removal is difficult, needs also exist for expending substantial amounts of manpower and materials, causes construction cost to increase.
Utility model content
The purpose of this utility model is in that to overcome the shortcoming of prior art, it is provided that a kind of form of construction work is flexible and changeable, workable, simple in construction, equipment cost are low and the convenient constructing tunnel central trench template of form removal.
The purpose of this utility model is achieved through the following technical solutions: constructing tunnel central trench template, it includes sliding beam, template body frame, template lift cylinder and template assembly, sliding beam is arranged on trestle, and can slide along the length direction of trestle, the two ends of sliding beam are respectively mounted template lift cylinder, the telescopic shaft of template lift cylinder is rotatablely equipped with pulley, template body frame is arranged at the lower section of sliding beam, the two ends of sliding beam are connected to a template lifting steel cable, the pulley of homonymy walked around by template lifting steel cable, and be connected with the end of template body frame, described template assembly is arranged on the lower section of template body frame, template assembly includes connector, master module and secondary template, the lower surface both sides of template body frame are respectively fixed with connector, the lower end of two connectors has been respectively articulated with a master module, secondary template raise-lower hydraulic is installed in the middle part of the lower surface of template body frame, secondary model sheetinstallat is on the telescopic shaft of secondary template raise-lower hydraulic, when the telescopic shaft of secondary template raise-lower hydraulic stretches out, master module cooperatively forms central trench structure with secondary template.
It is additionally provided with master module traction steel rope of cable between bottom and the sidewall of secondary template of described master module.
Described template assembly also includes positioning screw rod, and the two ends of positioning screw rod are pushed up in the middle part of the medial wall being pressed in two master modules respectively.
This utility model has the advantage that
1, central trench template can move together with trestle, it is possible to individually moves, and operator according to duty requirements, can select the move mode of central trench template, and form of construction work is flexible and changeable.
2, simple in construction of the present utility model, practicality is high, and equipment cost is low, has saved substantial amounts of manpower and materials for operator.
3, template assembly adopts split-type structural, when building, master module coordinates with secondary template, and is positioned by positioning screw rod, form central trench structure, during form removal, first pull down positioning screw rod, then pair template is promoted, what make master module and secondary template coordinates inefficacy, again through master module traction steel rope of cable by master module to traction in the middle of central trench, it is achieved master module and central trench inwall depart from, thus can form removal assembly easily and fast.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, constructing tunnel central trench template, it includes sliding beam 1, template body frame 2, template lift cylinder 3 and template assembly, sliding beam 1 is arranged on trestle, and can slide along the length direction of trestle, the two ends of sliding beam 1 are respectively mounted template lift cylinder 3, the telescopic shaft of template lift cylinder 3 is rotatablely equipped with pulley 4, template body frame 2 is arranged at the lower section of sliding beam 1, the two ends of sliding beam 1 are connected to a template lifting steel cable 5, the pulley 4 of homonymy walked around by template lifting steel cable 5, and be connected with the end of template body frame 2, described template assembly is arranged on the lower section of template body frame 2, template assembly includes connector 6, master module 7 and secondary template 9, the lower surface both sides of template body frame 2 are respectively fixed with connector 6, the lower end of two connectors 6 has been respectively articulated with a master module 7, secondary template raise-lower hydraulic 8 is installed in the middle part of the lower surface of template body frame 2, secondary template 9 is arranged on the telescopic shaft of secondary template raise-lower hydraulic 8, when the telescopic shaft of secondary template raise-lower hydraulic 8 stretches out, master module 7 cooperatively forms central trench structure with secondary template 9.
Further, being additionally provided with master module traction steel rope of cable 10 between bottom and the sidewall of secondary template 9 of described master module 7, master module 7 can be drawn by master module traction steel rope of cable 10 to centre, is conducive to master module 7 to depart from central trench inwall.
