Description
Technical field
The present invention relates to a kind of long girder construction composite product forming frock and forming method thereof.
Background technology
Long girder construction composite is made and is referred to that generally part length is longer, and length and width differ larger, is comprised of web and edge strip two parts, and version is " I " shape or " [" shape.And " I " shape structural member is when moulding, and " [" shape blank, by mode moulding " I " shape of combination, therefore " making of [" shape structural member is particularly important again 2 of first moulding.
For making things convenient for the operation of laying and curing process, long girder construction composite product normal operation male mould forming.Because beam edge strip size is little, the edge strip blank extremely easily runs off the resin near the mould end under the effect of temperature and pressure during curing, and slippage also easily appears in fiber, thereby cause the beam edge strip thinner near the die edge place, and inhomogeneous phenomenon also easily appear in edge strip thickness.
For guaranteeing the internal soundness of long girder construction part, use the technique cover plate, be generally an overall structure, can be metal, also can be vulcanized rubber.The metal integral cover plate is in long LiangRJiao place difficult forming, and easily occurs and the long beam blank phenomenon of not fitting, and namely build bridge in place, R angle, affect the inside parts quality, and vulcanized rubber integral body cover plate generally will be made first bogusware, utilizes bogusware to break through, and cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of " the long girder construction composite product forming frock of [" shape and forming method thereof, can effectively guarantee the external surface quality of long girder construction part, and reduce edge effect to the impact that beam edge strip thickness brings, reduced simultaneously production cost.
Technical scheme of the present invention: " the long girder construction composite product of [" shape forming frock, the both sides of shaping mould are provided with the technique filler strip, the lower limb of technique filler strip is concordant with the lower limb of shaping mould, the outside of shaping mould and technique filler strip is covered with the technique cover plate, and " the long girder construction composite product of [" type is positioned at the chamber that is made of shaping mould, technique filler strip and technique cover plate three; The technique cover plate is comprised of aluminium matter technique cover plate and polytetrafluoroethylene (PTFE) technique cover plate, wherein aluminium matter technique cover plate is that surface plate is positioned on three straight planes of technique cover plate, polytetrafluoroethylene (PTFE) technique cover plate is that surface plate bends to the radian plate according to the R angular shape, and this radian plate is positioned at the place, two R angles of technique cover plate.
A kind of " forming method of the long girder construction composite product of [" shape forming frock, adopt following steps:
1) uses " the long girder construction composite product of [" shape shaping mould laying blank;
2) use the wallpaper cutter with " the long girder construction composite product of [" shape both side edges beam bar is repaiied near the blank of shaping mould bottom surface and cut, and makes end face neat;
3) use two-sided tape the technique filler strip to be pasted the both sides of shaping mould, guarantee the technique filler strip and " interfering does not all appear in the long girder construction composite product edge of [" shape and shaping mould bottom surface;
4) aluminium matter technique cover plate and polytetrafluoroethylene (PTFE) technique cover plate are connected to become an integrated artistic cover plate with pressure sensitive adhesive tape;
5) place the technique cover plate.
The width of polytetrafluoroethylene (PTFE) technique cover plate is less than the gap between the adjacent two aluminium matter technique cover plates.
Beneficial effect of the present invention: the present invention reduces the impact that edge effect brings beam edge strip thickness by reserving certain this mode of process allowance (being generally 20mm-30mm) in edge strip theoretical margin, the design height of this duration girder construction composite product mould is definite by two parts stack, i.e. the theoretical size of beam edge strip and certain process allowance.The impact that edge effect when the adopting process filler strip not only can effectively reduce long girder construction composite product curing molding brings part, and can well guarantee the thickness of beam edge strip by the thickness of technique filler strip, make it within the margin of tolerance that design allows.If technique filler strip and shaping mould are designed to integrative-structure, die face can be comparatively complicated, and both inconvenient part laying process operations was unfavorable for again mould machining.And adopt the scheme of independent design technology filler strip, and both can satisfy technological requirement, can reduce again the difficulty of processing of mould, make things convenient for simultaneously the operation of laying operation, but the Effective Raise operating efficiency saves production cost.
Used a minute body technology cover plate, two types of materials, a class are aluminum, and the width on three straight planes of long beam is removed the R angle part for long beam section, and length is identical with long beam mould; One class is polytetrafluoroethylene (PTFE), respectively puts one at the place, two R angles of long beam, and length is identical with long beam mould, and width is slightly less than the gap between two aluminum technique cover plates, and the polytetrafluoroethylene (PTFE) quality is softer, can be good at sticking blank, satisfies the technological requirement at place, R angle.
