Abstract
The utility model relates to a centrifugal forming die for a concrete rectangular pile, comprising two symmetrical grooved type die structures. Each grooved type die comprises a groove having a cross section which is a non-isosceles right triangle or a rectangle with the length being 1.5 times longer than the width, a matchboard fixedly connected to the groove, a centrifugal balancer, a reinforced longitudinal plate, a reinforced ring plate, a semicircular running wheel, and end plates respectively disposed at two axial ends of the groove. An outer wall of a cylindrical body is evenly and symmetrically connected to two similar inverted-U-shaped box girders. The inverted-U-shaped box girders can directly adopt channel steels, and opening ends of the box girders are welded to each outer wall of the cylindrical body. The channel steels are welded with the running wheels and the reinforced ring plates into one piece. The centrifugal forming die for a concrete rectangular pile is advantageous in that a forming die can have good dynamic balancing performance and better strength, and the cylindrical wall of the die is not easy to be deformed; the rigidity and stability of the forming die are improved, and the structure is simple, reasonable and economical.
Description
Technical field
The utility model relates to a kind of concrete rectangular stake centrifugal moulding mould for the production of making centrifugal prestressed concrete rectangular pile.On the basis of the advantage of each prestressed pile mould, the directionality requirement arranged according to stake in that building structure is stressed, for structure tension performance and the suffered load that makes stake is complementary, and then can give full play to the anti-bending bearing capacity of himself and the mould of new type developing.Its intensity is better, and the barrel of mould is difficult for deforming.
Background technology
Concrete-pile comprises the non-prestressed stake of tradition and prestressed centrifugally stake, and the prestressed centrifugally stake comprises pile for prestressed pipe, prestress square pile, the stake of prestressing force ring.The production of tradition prestressed centrifugally stake all be by by the centrifugal moulding mould of feeding full material (concrete) through matched moulds, stretch-draw and on centrifuge High Rotation Speed form.The high speed centrifugation of concrete in mould is so that concrete is more closely knit, thus the raising bearing capacity of pile.And these types can carry out large-scale industrial production.
In the prior art, centrifugal shaper for concrete square pile for the production of prestress square pile, by two block-shaped just as, make-up and the grooved mould that connects and be connected in mould shaft and form to the end plate at two ends, to be that isosceles right triangle or one are wide by a cross section be long half rectangular groove for every grooved mould, be fixedly connected on the matchboard of the radially notch both sides of each groove, be fixedly connected on reinforcement and the enforced loop plane in each groove outside, the a plurality of semicircular steel construction running wheel that is fixedly connected on each groove outside forms, described two groove-shaped molds are bolted matchboard and are integrated, two ends and end plate are connected to a fixed, thereby form the cylindrical body of the rectangular column cavity of intracavity section, also be evenly distributed with a plurality of enforced loop planes and a plurality of isodiametric ring-type running wheel on this tubular body wall, simultaneously, on barrel, also be evenly distributed with a plurality of vertical muscle of reinforcement that are parallel to tubular cuboid center line, these are strengthened vertical muscle and are the strip steel board, the end plate at they and two ends, each running wheel, each enforced loop plane is welded as a whole.
When existing mould was produced, the centrifugal moulding mould quality of filling full concrete material was very large, when its on centrifuge during High Rotation Speed, centrifugal force is very large.So the requirement of strength to centrifugal shaper for concrete square pile is high, the intensity of centrifugal moulding mould still can not be satisfactory in the prior art, deformation easily occurs in the barrel of mould, directly affects the quality of concrete square pile centrifugal forming, concrete density behind the centrifugal forming.
Summary of the invention
The utility model aims to provide a kind of concrete rectangular stake centrifugal moulding mould, and it is low to be beneficial to reach making die steel amount, reduces the mould deadweight; Mould strength is high, and balance when centrifugal has been strengthened packing after the concrete centrifugal moulding.
For achieving the above object, the technical solution adopted in the utility model provides a kind of concrete rectangular stake centrifugal moulding mould, the two ends of this mould are connected with end plate, wherein: this mould includes two mutual symmetrical grooved moulds, the cross section of every grooved mould is a right angle triangle, two grooved moulds fasten and form rectangular tubular cell body, two grooved mould fastening places are provided with respectively matchboard and sealing gasket, be provided with the reinforcement stringer board that polylith is connected with the two ends end plate along described tubular cell body outer wall axially parallel, also be evenly distributed with a plurality of enforced loop planes and a plurality of isodiametric ring-type running wheel on the described tubular cell body outer wall, be connected with enforced loop plane by strengthening stringer board, middle part, limit Thursday is equipped with the case beam outside two grooved moulds, evenly be provided with a plurality of centrifugal balancers on wherein in the middle part of the corresponding a pair of case beam, the openend of these shape case beams is welded on the barrel of cylindrical body, simultaneously, described door shape case beam and each running wheel, each enforced loop plane is welded as a whole.
Effect of the present utility model is that this structure helps mould to have good dynamic balance, and its intensity is better, and the barrel of mould is difficult for occuring deformation.Improved rigidity and the stability of mould, economical, simple and reasonable simultaneously.Directly adopt channel-section steel further to reduce cost.Saving steel 20% of the present invention improves intensity more than 30%.
