Description
Technical field
It the utility model is related to a kind of gutter template, specifically a kind of railway tunnel center gutter stock mould
Plate.
Background technology
At present, when all kinds of highways, railway are when the filling formwork erection construction of tunnel inverted arch, tunnel center gutter, which generally uses, to be divided
Block template assembly formwork erection, the use of this template can greatly increase the formwork erection time, and in the prior art, side form and bed die are splits
, side form is spliced and combined using the small punching block of polylith, and bed die is then made of steel plate or plank.Not only process is numerous for processing side form and bed die
Miscellaneous and influence construction speed, and be linearly difficult to control, appearance is poor after causing form removal, front and rear mixed mud between pouring section
There are faulting of slab ends, causes tunnel center gutter cover coarse, not smooth, seriously affects tunnel drainage, damage to tunnel roadbed.
The content of the invention
The purpose of this utility model is the deficiency for current tunnel center gutter template, there is provided a kind of tunnel central row
Ditch typified form, the typified form pour faulting of slab ends existing for mixed mud between section before and after solving tunnel center gutter, row
Ditch face is coarse, not smooth, seriously affects tunnel drainage, the problem of damaging to tunnel roadbed.And typified form structure letter
Single, stability is high, convenient disassembly, and operation is easy at the scene, while recoverable, saves construction cost.
The technical solution of the utility model is:A kind of tunnel center gutter formed molding board, including the first side template,
Two side templates, the first trapezoid template, the second trapezoid template, end template, supporting rack, top template, lifting earhole and steel wire lifting rope.
A kind of tunnel center gutter formed molding board, the first side template, the both ends of the second side template are respectively welded at
First trapezoid template, the second trapezoid template both sides side on, the both ends of end template are respectively welded at the first trapezoid template, second
On trapezoid template bottom face；Bottom face of the two sides of end template respectively with the first side template, the second side template welds together,
Trapezoidal supporting rack is mounted among the longitudinal direction of the first side template and the second side template, upper cover model sheetinstallat is fixed on first
Trapezoid template, the second trapezoid template, the first side template, the upper end of the second side template, the first lifting lug and the second lifting lug are installed respectively
The first trapezoid template, the second trapezoid template upper end are fixed on, the first lifting lug and the second lifting lug upper end are respectively equipped with circular hole；Steel wire carries
The both ends of lifting rope are equipped with hook, and the hook at steel wire lifting rope both ends is mounted on the circular hole on the first lifting lug and the second lifting lug respectively
It is interior, form a kind of tunnel center gutter formed molding board.
The beneficial effects of the utility model are：Compared with prior art, which solves
Faulting of slab ends existing for mixed mud between section is poured before and after the gutter of tunnel center, gutter cover is coarse, not smooth, seriously affects tunnel
Draining, the problem of damaging to tunnel roadbed.And typified form is simple in structure, stability is high, and convenient disassembly, operates at the scene
Easily, while recoverable, construction cost is saved.
Brief description of the drawings
The utility model is further described below in conjunction with drawings and embodiments.
Fig. 1 is the structure diagram of the utility model frock；
Fig. 2 is railway tunnel center gutter formed molding board and inverted arch fill concrete cross-sectional structure schematic diagram.
In fig. 1 and 2：1. the first side template, 1 ' the second side templates of, 2. first trapezoid templates, 2 ' second are trapezoidal
Template 2 ', 3. end templates, 4. supporting racks, 5. cable wire lifting ropes, 6. circular holes, 7. upper cover templates, 8. first lifting lugs, 8'. second
Lifting lug, 9. inverted arch templates, 10. concrete.
Embodiment
In the embodiment for Fig. 1 that the utility model provides, a kind of tunnel center gutter formed molding board, the first side template
1st, the both ends of the second side template 1' be respectively welded at the first trapezoid template 2, the second trapezoid template 2' both sides side on, end template
3 both ends are respectively welded at the first trapezoid template 2, on the second trapezoid template 2' bottom faces；The two sides of end template 3 are respectively with
One side template 1, the bottom face of the second side template 1' weld together, in the longitudinal direction of the first side template 1 and the second side template 1'
Between be mounted with trapezoidal inner support frame 4, upper cover template 7 is fixed on the first trapezoid template, the second trapezoid template, the first side
The upper end of template, the second side template, the first lifting lug 8 and the second lifting lug 8' are fixed on the first trapezoid template, the second ladder respectively
Shape template upper end, the first lifting lug 8 and the second lifting lug 8' upper ends are respectively equipped with circular hole 6；The both ends of steel wire lifting rope 5 are equipped with hook,
The hook at steel wire lifting rope both ends is mounted in the circular hole 6 on the first lifting lug and the second lifting lug respectively, forms a kind of tunnel center
Gutter formed molding board a.
In the embodiment of Fig. 2, tunnel center gutter formed molding board a is installed among the longitudinal direction of inverted arch template,
The casting concrete in inverted arch template 9, after waiting in inverted arch template 9 casting concrete maintenance solidification sizing, steel wire lifting rope 5 is carried
Rise, remove tunnel center gutter formed molding board a, complete first segment tunnel center gutter and pour.To the tunnel center of dismounting
After gutter formed molding board carries out maintenance maintenance, tunnel center gutter formed molding board is installed in next section of tunnel longitudinal direction
The heart, carries out next section of tunnel center gutter and pours, until whole tunnel center gutter is poured completion.
