Background technology
Domestic defeated drainpipe mostly adopts Prestressed concrete cylinder pipe and concrete reinforced pipe at present; Though pipe of concrete has intensity height, good rigidity, advantage that cost is low than steel pipe, cast iron pipe, bellows, this three big problem of sealing property, decay resistance and current trafficability characteristic fails to obtain basic improving all the time.So occurred composite glass steel pipe now; The characteristics that it has: light weight, high-strength, corrosion-resistant, insulation, heat insulation, inner wall smooth, the little deficiency that be able to well remedy pipe of concrete of fluid resistance; But glass reinforced plastic pipe and RPM receive the restriction of factors such as rigidity, hardness, buried depth, backfill, and the glass fibre reinforced plastics concrete multiple tube arises at the historic moment.The glass fibre reinforced plastics concrete multiple tube receives the restriction of moulding process at present; The glass fibre reinforced plastics concrete multiple tube of producing is second-rate, and it is in forming process, and the glass reinforced plastic pipe interface receives axial force easily and produces damage; The demoulding simultaneously is inconvenience comparatively, has influenced the Forming Quality and the production efficiency of goods.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of being convenient in demoulding, the vertical forming composite glass steel pipe mould that the glass reinforced plastic pipe interface is not damaged.
The technical scheme of the utility model employing is for this reason: the utility model comprises internal mold, the external mold of working in coordination, and is arranged on the glass reinforced plastic pipe between internal mold, the external mold, and internal mold, external mold, glass reinforced plastic pipe upper and lower side are established the backform and the base of fixation respectively;
Said backform: comprise 1) is arranged in interior locating detent between internal mold, the glass reinforced plastic pipe; 2) be arranged in the outside fix pawl of external mold medial and lateral; 3) be arranged at internal mold, external mold upper surface and with its locating surface that closely contacts;
Said base: vertical contact site of external mold on it and glass reinforced plastic pipe is provided with one section awl section;
Said external mold: be the single radial cut formula, be provided with the jacking mechanism of axial setting at its circumferential position, jacking mechanism comprises from the jacking screw rod between external mold jacking to external mold and the glass reinforced plastic pipe with the jacking screw rod and is positioned at the location-plate on the external mold.
Said internal mold: be the single radial cut formula, but the internal mold side is provided with the closing device that makes the internal mold folding.
The utility model has the advantages that: 1) backform is made up of locating detent, locating surface, utilizes the difference of inside and outside mould and glass reinforced plastic pipe diameter, makes locating detent have the effect of locating inside and outside mould and glass reinforced plastic pipe, to reach the purpose of guaranteeing the interface size; Utilize the difference in height on plane on inside and outside mould and the glass reinforced plastic pipe; Utilize locating surface to guarantee that backform is when receiving concrete material awl and concrete downforce; Only interior external mold is stressed, and the purpose that glass reinforced plastic pipe does not stress has avoided the glass reinforced plastic pipe axially loaded to destroy interface; 2) base is basic with the conventional vertical mould that vibrates, but adopts taper design at external mold and glass reinforced plastic pipe contact site, guarantees the smooth and easy of external mold and goods lifting; 3) external mold is the single radial cut formula, and adjustable jacking mechanism is housed, the single radial cut door-plate; Utilize jacking mechanism, will be used to lift by crane and the jacking screw device that overturns between interior external mold and glass reinforced plastic pipe; When goods reach design strength, utilize external mold and the jacking screw rod that is embedded in the goods, directly lifting, upset.After withdrawing from jacking mechanism, utilize the open-and-close mechanism of single radial cut door-plate, change mould diameter, handle thereby carry out the demoulding.
