Description
Technical field
The utility model relates to a kind of constructing tunnel templates more particularly to a kind of collapsible tunneled central ditch construction to use
Template.
Background technique
Modern tunnel structure is complicated, is filled concrete construction after inverted arch concrete construction, at this moment needs to pour
Outpour central ditch.
Current construction method is: excavation operation is carried out first in front of tunnel；Then inverted arch lining cutting work is carried out at rear
Industry: preparation of construction → inverted arch excavates base treatment → preliminary bracing laying waterproof layer → reinforcing bar binding, installation inverted arch template → and faces upward
Arch filling concrete → inverted arch demoulding (removing inverted arch template) → Central drain surveying and locating → Central drain formwork erection → inverted arch is filled out
It fills filling concrete → maintenance to intensity and meets machine-walking → end.
The central ditch template of existing use, as China Patent Publication No. 206769954U discloses a kind of tunneled central U
Shape gutter concrete-pouring template support construction and formwork for placing, publication date 2017-12-19, including two along the same as always
The extensible member of line direction setting is equipped with revolving part, the inner end of one of extensible member and the positive spiral shell of revolving part between two extensible members
Line connection, the inner end of another extensible member are connect with revolving part left-hand thread, and the outer end of extensible member is respectively equipped with top tight pieces.
But the central ditch template used in the prior art is fixed structure, is only used for fill concrete construction, does not have
It is fully used, utilization rate is lower.
Summary of the invention
The purpose of the utility model is to overcome the above problems of the existing technology, provide a kind of collapsible tunneled central
Ditch construction template.The utility model can allow central ditch template sufficiently to be used, and being by central ditch stencil design can
The structure of expansion reduces the weight of inverted arch template as part inverted arch template in inverted arch construction, improves central ditch mould
The utilization rate of plate reduces the state basic policy using environmental emission reduction of steel.
To achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of collapsible tunneled central ditch construction template, it is characterised in that: including bed die, stringer, side form and support
Very heavy, stringer is fixed on bed die, and two groups of side forms are hinged with bed die two sides respectively, is lining cutting center when two groups of side forms fold
Ditch state, when lining cutting central water ditch state, support very heavy both ends to be hingedly connected on two groups of side forms, and whens two groups of side forms expansion is
Lining cutting inverted arch state, when lining cutting inverted arch state, support very heavy one end to be articulated on side form, and the other end is articulated on stringer.
Two groups of side forms are symmetricly set on bed die two sides.
The bed die is one group, and two sides are hinged with the hinge ear on two groups of side forms respectively.
The very heavy support that both ends are hingedly connected on two groups of side forms when the lining cutting ditch is 9.
It is 19 that it is very heavy, which to be articulated with support that the other end on side form is articulated on stringer, for one end when the lining cutting inverted arch.
Electric block is used when the side form folds, electric block is fixed on stringer, the steel cable of electric block with
The cucurbit hinge ear connection being arranged on side form.
The electric block is 8.
Using utility model has the advantages that
After the utility model, central ditch template is allowed sufficiently to be used, is that can open up by central ditch stencil design
The structure opened reduces the weight of inverted arch template as part inverted arch template in inverted arch construction, improves central ditch template
Utilization rate, reduce the state basic policy using environmental emission reduction of steel.

Specific embodiment
Embodiment 1
A kind of collapsible tunneled central ditch construction template, including bed die 1, stringer 2, side form 3 and support very heavy 4, are indulged
Beam 2 is fixed on bed die 1, and two groups of side forms 3 are hinged with 1 two sides of bed die respectively, and two groups of side forms 3 are lining cutting central water when folding
Ditch state, when lining cutting central water ditch state, support very heavy 4 both ends to be hingedly connected on two groups of side forms 3, and two groups of side forms 3 are when being unfolded
Lining cutting inverted arch state, when lining cutting inverted arch state, support very heavy 4 one end to be articulated on side form 3, and the other end is articulated on stringer 2.
In the present embodiment, two groups of side forms 3 are symmetricly set on 1 two sides of bed die.
In the present embodiment, the bed die 1 is one group, and two sides are hinged with the hinge ear on two groups of side forms 3 respectively.
In the present embodiment, both ends are hingedly connected on two groups of side forms 3 when the lining cutting central water ditch state support very heavy 4
It is 9.
In the present embodiment, one end is articulated with the other end on side form 3 and is articulated with the branch on stringer 2 when the lining cutting inverted arch state
Supportting very heavy is 19.
In the present embodiment, electric block 5 is used when the side form 3 folds, electric block 5 is fixed on stringer 2, electricity
The cucurbit hinge ear 6 being fixedly installed on the steel cable and side form of dynamic cucurbit 5 connects.
