Technical scheme of the present invention is as follows:
A kind of tunnel invert termination combined steel, be is characterized in that: mainly comprise cope match-plate pattern, lower bolster and connecting bolt, linked together between cope match-plate pattern and lower bolster by connecting bolt, in bury waterstop and be sandwiched between cope match-plate pattern and lower bolster template.
Described lower bolster is the fan-shaped template by design inverted arch section sectional making, lower bolster bottom surface, end face and both sides are provided with steel plate flange, the curved plate flange of lower bolster bottom surface, end face is convenient to bury waterstop in horizontal, flat folder, vertical ribbing between the steel plate flange of lower bolster bottom surface, end face, and lower bolster both sides steel plate flange is convenient to be connected between template.
Described lower bolster bottom part ring is provided with reinforcing bar locating hole to by reinforcement placement form.
Described lower bolster height gets the half that design two serves as a contrast inverted arch thickness.
Described cope match-plate pattern, make according to lower bolster fragment size length, bottom cope match-plate pattern, curved plate flange is identical with lower bolster top steel plate flange arc, is convenient to bury waterstop in flat folder.
Described cope match-plate pattern height is filled apical side height according to inverted arch and is made.
Described cope match-plate pattern both sides are fixed by draw-in groove with longitudinal inverted arch sidewall template.
Bottom described cope match-plate pattern, steel plate flange is corresponding with lower bolster top steel plate flange punches, and is convenient to connecting bolt and passes to connect cope match-plate pattern and lower bolster.
Waterstop horizontal positioned is buried in described, half is fixed in upper and lower template steel plate banjo clip seam, and second half directly imbeds in two lining inverted arch concrete, unaffected in work progress, ensure that the precision that waterstop is located, thus ensure that the guarded drainage effect of inverted arch.
Described lower bolster bottom outside is provided with outer subsides waterstop.
Beneficial effect
The invention has the advantages that: first, middle buried water stop horizontal positioned, half is fixed in bolster flange crack, second half is directly imbedded this section two and serves as a contrast in inverted arch concrete, unaffected in work progress, ensure that the precision that waterstop is located, thus ensure that the guarded drainage effect of inverted arch; The second, formed a whole by steel form by composite assembly, replace traditional lumps of wood to support scattered assembling construction, manually high in conjunction with mechanical assembled efficiency, human assistance machinery, change the drawback that mechanical assistance is in the past artificial, labour intensity is low, and speed of application is fast.

Detailed description of the invention
As Figure 1-3, tunnel invert termination of the present invention combined steel, mainly comprises: cope match-plate pattern, lower bolster and connecting bolt.Adopt bolt to be linked together by bolster, in bury waterstop and be sandwiched between bolster, every block template also connects into an entirety by side flange bolt.By this template system, achieve in good inverted arch termination constuction joint and bury the fixing of waterstop, thus ensure that excellent waterproof effect.
Technical scheme of the present invention is as follows:
A kind of tunnel invert termination combined steel, is mainly comprised cope match-plate pattern 2, lower bolster 3 and connecting bolt 7, is linked together between cope match-plate pattern 2 and lower bolster 3 by connecting bolt 7, in bury waterstop 5 and be sandwiched between cope match-plate pattern 2 and lower bolster 3 template.Wherein, lower bolster 3 is the fan-shaped templates by design inverted arch section sectional making, lower bolster 3 bottom surface, end face and both sides are provided with steel plate flange, the curved plate flange of lower bolster 3 bottom surface, end face is convenient to bury waterstop 5 in horizontal, flat folder, vertical ribbing between the steel plate flange of lower bolster 3 bottom surface, end face, and lower bolster 3 both sides steel plate flange is convenient to be connected between template.Lower bolster 3 bottom part ring is provided with reinforcing bar locating hole 4 to by reinforcement placement form, lower bolster 3 highly gets the half that design two serves as a contrast inverted arch thickness, cope match-plate pattern 2, make according to lower bolster 3 fragment size length, bottom cope match-plate pattern 2, curved plate flange is identical with lower bolster 3 top steel plate flange arc, is convenient to bury waterstop 5 in flat folder.Cope match-plate pattern 2 height is filled apical side height according to inverted arch and is made, and cope match-plate pattern 2 both sides are fixed by draw-in groove with longitudinal inverted arch sidewall template 1.Bottom cope match-plate pattern 2, steel plate flange is corresponding with lower bolster 3 top steel plate flange punches, and is convenient to connecting bolt 7 and passes to connect cope match-plate pattern 2 and lower bolster 3.
