Number in the figure: on the left of 1 brace, 2 bed dies, 3, mould, 31 wing limits, upper left, 4 hang mould, 61 upper right wing limits on the right side of connecting rod, 5 formboard supporting rods, 6.
By detailed description of the invention, explanation is further explained to technical solution of the present invention below in conjunction with accompanying drawing.
Detailed description of the invention
See Fig. 1, Central drain template, forms by organizing repetitive more, often organize unit comprise bed die 2 that a split arranges, a U-shaped left and right side form 3,6, multiple brace 1, multiple suspension connecting rod 4 and multiple formboard supporting rod 5; Left and right side form 3,6 is separately fixed at above the both sides of bed die 2, wing limit, upper left 31 and the upper right wing limit 61 of left and right side form removably connect with corresponding brace 1 respectively, brace 1 is detachably connected on and hangs on connecting rod 4, and the two ends hanging connecting rod 4 are locked in steel rail web place; Formboard supporting rod 5 is supported on inside left and right side form 3,6 and locates for the spacing of left and right side form 3,6.
During concrete enforcement, left and right side form 3,6 and bed die are provided with corresponding fixing hole, and left and right side form 3,6 and bed die are bolted to connection.Brace 1 is provided with draw-in groove, and the upper limb limit expanded joint of draw-in groove and side form is fixed.Also can adopt the connected mode shown in Fig. 2, state the trapezoidal guide-localization groove that brace 1 is provided with the narrow bottom width of mouth, the upper limb limit of left and right side form is the trapezoidal side matched with guide-localization groove shape, and left and right side form slips into guide-localization groove with fixing by upper limb limit.
Hanging connecting rod 4 and rail web is tighten up a screw to fix with the web of the rail by tightening connecting rod.Hanging connecting rod 4 also can be the fine-tuning stretching structure of length, by the elongation to suspension connecting rod 4, makes two ends and web of the rail close contact, is fixed in track by suspension hanging by expanded joint mode.
In model sheetinstallat, first hang connecting rod 4 and be bolted together with draw-in groove brace 1; Then ditch side form 3 being installed, after installation, arranging that 7 roads hang connecting rod 4 according to often arranging rail (25m); Hang connecting rod to support 4 and lock web of the rail place at steel rail web; The upper limb limit expanded joint of the draw-in groove of brace 1 and left and right side form is utilized to fix after completing.Tiling ditch bed die 2 after completing also is in ditch bed die 1 drilling on inner side according to 3.5m/ and is used for fixing bed die and side form; For ensureing that ditch template does not run mould when concrete construction, according to ditch inside clearance processing formboard supporting rod 5, formboard supporting rod 5 centrally ditch axially spaced-apart is arranged in inside left and right side form 3,6, arranges according to 1.5-2.5m/ place; Often needing to encrypt between adjacent 2 bed dies and using the shuttering supporting lumps of wood to stitch compacting together, hang connecting rod 4 centrally ditch axially spaced-apart arrangement, the spacing hanging connecting rod 4 is 3-4m.
