Description
Technical field
The present invention relates to a kind of pattern that is specially adapted for making tubulose or reinforcement goods, particularly relate to a kind of track-tracking concrete segment die.
Background technology
From Britain engineer Brunel in 18th century the forties first Application shield method build the subfluvial tunnel and cross Britain's Times river success, the history in existing more than 100 year so far.In the follow-up years because shield method extensively in vogue in the tunnel construction field, begin to rise with the supporting segment die of shield method construction with some countries headed by Italy, Britain, the Germany etc. and design manufacturer.
Because early stage shield-tunneling construction tunnel diameter is less; The design of concrete section of jurisdiction does not have the mutual interlock between the complicated section of jurisdiction, and profile is fairly simple, so concrete segment die generally adopts the convertible die sinking of hinge; Promptly hold the mould side form to fix on the bed die with hinges fixing; End, side form are around the hinge axis die sinking of overturning during die sinking, and this mould designs and produces simply in the application in early days, and size is accurate and sturdy and durable in the use.But continuous development science and technology progress with rapid changepl. never-ending changes and improvements along with society; The shield-tunneling construction diameter presents increasing trend; The design of concrete section of jurisdiction begins to appear at the profile that the cambered surface contact site has the mutual interlock of notch cuttype; Therefore adopt the concrete segment die of hinge upset die sinking mode, the more and more incompatible manufacturing with the occlusal concrete of major diameter arc section of jurisdiction, the form that is showed is that local element on the moulding face is not on same radius; Interfering with each other when the identical profile that Mould design profile and product therefore when fixed rotating shaft rotates die sinking, inevitably can occur is separated; Be the undercut phenomenon, make shaped article corner angle part after the die sinking by damaged disappearance, even undercut phenomenon in various degree also can appear in some external very well-known convertible concrete segment dies of the hinge that manufacturer produced when the product depanning.
In order to improve the die sinking undercut phenomenon of convertible concrete segment die; Some segment die producers with the technology of the emphasis headed by the Japanese manufacturer begin to carry out the parallel-moving type concrete segment die; The side form that promptly when the mould die sinking, has moulding face is along being fixed on the parallel mobile die sinking of pulley on the bed die; This mould has well solved mould at the implementation initial stage to have between side form and the moulding section of jurisdiction of profile and interferes the undercut phenomenon, and is therefore extensively carried out, but along with the further increasing of concrete section of jurisdiction intended diameter; The lasting increase of concrete section of jurisdiction volume and weight makes that the profile template size of mould is also corresponding to be continued to increase; And the technological biside plate owing to mould after the die sinking of existing parallel-moving type die sinking becomes parastate, and opening is little, and the distance between the moulding concrete section of jurisdiction is often abundant inadequately; So occur collision phenomenon when getting from mould easily, also have to be exactly heavy side form and to open that back side form support arm will receive very big stress and easy deformation and the punching block precision is reduced flat in thick and heavy concrete section of jurisdiction.Therefore drawbacks such as deterioration in accuracy and operation inconvenience appear in parallel-moving type concrete segment die easily when the concrete section of jurisdiction of production modern designs.
Summary of the invention
