Abstract
The utility model provides a feeding device for molding a pipe core of a pre-stress steel cylinder concrete pipe. The diameter of the bottom surface of a tapered device is the same as the outer diameter of a steel cylinder in the pipe core; the edge of the tapered device is provided with a plurality of grooves in a cutting manner and a bulge is formed between each two adjacent grooves. The feeding device provided by the utility model has a simple structure, can prevent the steel cylinder from being extruded in a single direction to be deformed, and also can ensure the uniformity, the synchronicity and the homogeneity of concrete casting.
Description
Technical field:
The utility model belongs to the moulding of a kind of pipe of concrete tube core and uses equipment, particularly a kind of Prestressed concrete cylinder pipe tube core moulding feeder.
Background technology:
Because the structure more complicated of Prestressed concrete cylinder pipe; Especially tube core, it is formed by adding a steel cylinder in inside and outside two layer concretes, in the tube core moulding; Refill inside and outside mould after needing to be installed in steel cylinder on the mold base, carry out concreting after buckling feeder.
At present; If a kind of taper feeder of feeder group (as shown in Figure 1) that generally uses; Its bottom surface diameter is identical with internal mold 1 external diameter; Elder generation on feeder, lets concreting concrete flow into uniformly along feeder through the method that shakes then and accomplishes concrete building in the mould in feeding.But because the bottom surface girth of feeder is identical with the internal mold external diameter; So in the process of building; After always filling was expired near internal mold one side, concrete was crossed steel cylinder and is recharged the side near external mold 2, and the major defect of such casting method is: can't guarantee in the concreting process that 1, the concrete in the inside and outside mould of tube core rises synchronously; Can't guarantee the uniformity of the concrete thickness in the inside and outside mould, thereby make steel cylinder 3 folk prescriptions produce distortion to being squeezed.2, in the process of building; Because concrete need be crossed steel cylinder and recharge the side near external mold; The concrete homogeneity in the outside reduces in so just causing, because concrete will certainly produce stone in the process of vibrations sinking is found through site observation; After filling is expired in the internal mold; Cross the concrete head and shoulders above designing requirement of content of mortar in the concrete of steel cylinder, change has taken place with regard to the match ratio that has caused inside and outside mould inner concrete in this, causes pipe of concrete in-core, outer concrete homogeneity to reduce.
Summary of the invention:
The purpose of the utility model just is to overcome the deficiency that exists in the above-mentioned prior art, and a kind of Prestressed concrete cylinder pipe tube core moulding feeder is provided, uniformity, synchronism and homogeneity that this device structure is simple, can guarantee blanking.
As above design; The technical scheme of the utility model is: a kind of Prestressed concrete cylinder pipe tube core moulding feeder; Comprise the taper body; It is characterized in that: the external diameter of steel cylinder is identical in the bottom surface diameter of taper body and the tube core, goes out a plurality of grooves in the edge cuts of taper body, and make form between per two adjacent grooves protruding.
Above-mentioned a plurality of groove evenly distributes along the edge of taper body.
The diameter of above-mentioned a plurality of grooves is with identical with the external diameter of tube core internal mold.
The equal diameters of above-mentioned each groove.
The utlity model has following advantage and good effect:
1, the design is when concreting; Concrete in the inside and outside mould of tube core is risen synchronously; The external mold inner concrete exceeds internal mold inner concrete 300-500mm, so just can guarantee the uniformity of the concrete thickness in the inside and outside mould, avoids the steel cylinder folk prescription to produce distortion to being squeezed.
2, the design can realize double-deck feeding; The concreting tube core internal mold that flows down along groove; Along the concreting tube core external mold that boss flows down, blanking velocity can be confirmed according to caliber and concrete performance, has so just guaranteed uniformity, synchronism and the homogeneity of blanking.
Description of drawings:
Fig. 1 is the work sketch map of existing feeder.
Fig. 2 is the front view of the utility model.
Fig. 3 is the vertical view of the utility model.
The specific embodiment:
As shown in the figure: the external diameter of steel cylinder 3 is identical in a kind of Prestressed concrete cylinder pipe tube core moulding feeder, the bottom surface diameter of taper body 4 and tube core, goes out a plurality of grooves 5 in the edge cuts of taper body, and makes and form protruding 6 between per two adjacent grooves.Above-mentioned a plurality of groove evenly distributes along the edge of taper body, and the equal diameters of these grooves, and diameter is with identical with the external diameter of tube core internal mold 1.
The utility model can be realized double-deck feeding; The concreting tube core internal mold 1 that flows down along groove; Along the concreting tube core external mold 2 that boss flows down, blanking velocity is confirmed according to caliber and concrete performance, has so just guaranteed uniformity, synchronism and the homogeneity of blanking.
