The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, embodiment 1, the technical scheme that is adopted in the present embodiment is: the solid side's stake of prestressing force is made up of cage of reinforcement and concrete, reinforcing cage is by main muscle and spiral bar 11 welds or colligation forms, cage of reinforcement is formed to several concentric reinforcing cages by one, the quantity of its reinforcing cage is relevant with the dowel section area size, cloth adhesion of tendon and muscle after injury reason, the shearing resistance of pile body, anti-bending strength height. Main muscle 1,2,3,4 is formed a reinforcing cage, and main muscle 5,6,7,8 is formed a reinforcing cage.
Cage of reinforcement master muscle can be presstressed reinforcing steel or non-prestressed and presstressed reinforcing steel combination layout; Promptly main muscle 1,2,3,4 all is a presstressed reinforcing steel; Perhaps main muscle 1,3 is a presstressed reinforcing steel, and main muscle 2,4 is a non-prestressing tendon.Main muscle can be spiral ribbed reinforced bar, steel strand, helicla flute rod iron; According to different its stretch-draw values of main muscle can for rebar standards intensity 70%, 80% in addition reach about 85%.Employing machinery vibrates, the moulding of dither mode, makes concrete structure closely knit.Concrete design strength is not less than the C60 grade.In solid side's stake termination concrete pile point or flanged plate can be set, the connection between the solid side's stake of prestressing force can be multiple modes such as welding, mechanical connection.According to conditions such as square arrangement of reinforcement situation, lifting methods, single pile length is the longest can be reached for 30 meters.
Main muscle is in the connection and reasonable arrangement in stake cross section, and main muscle is evenly arranged as far as possible; Satisfying under the prerequisite of protective layer thickness, main muscle is being arranged in the outside downwards as far as possible; The waist muscle is not set in the stake cross section structure.
The former of the solid side's stake of prestressing force, its first half is that reinforcing cage welding machine, bottom are moulding form; Directly be discharged in the counterdie after the welding, finish dither moulding behind the cloth, its device interior is provided with steam curing apparatus, is with the film maintenance.
The utility model is compared with similar stake, its reinforcing cage is welded by main muscle and spiral bar or colligation forms, cage of reinforcement is formed to several concentric reinforcing cages by one, the quantity of its reinforcing cage is relevant with the dowel section area size, cloth adhesion of tendon and muscle after injury reason, satisfying under the prerequisite of protective layer thickness, main muscle is being arranged in the outside downwards as far as possible; The waist muscle is not set in the stake cross section structure.Shearing resistance, the anti-bending strength of pile body are increased.Employing machinery vibrates, the moulding of dither mode, makes concrete structure closely knit.Concrete design strength is not less than the C60 grade, and the length of side is identical to be the stake of same specification, the bearing capacity of single pile height.
