Description
Technical field
The present invention relates to one both to hale without the need to end plate, concrete tubular pile that rod iron is haled can be realized again and component is general hales nut and rod iron, belong to single-unit stake and manufacture field.
Background technology
The applicant is all " pushes up pile extension and prefabricated component under upper spiral shell " in first patent CN100348803C, title, high-tensile fastener is female thread structure or in external thread structure or in interior interface arrangment or in outer interface arrangment, the fastener Qiang Di center of female thread structure, external thread structure, interior interface arrangment, outer interface arrangment has reinforced hole, the periphery of reinforced hole is reinforcing bar end upset chuck, and the heading of reinforcing bar is connected in chuck.Some longitudinal reinforcements in prestressing force prefabricated component and circumferential reinforcement form prefabricated component cage of reinforcement, and the two ends of some longitudinal reinforcements are connected in the reinforcing bar end upset chuck of high-tensile fastener respectively.The two ends upsetting of some longitudinal reinforcements becomes heading to be stuck in rise draws in the heading chuck of nut and top is drawn in the heading chuck of nut, the end of high-tensile fastener adopts respectively and is bolted on fixed head and rises on arm-tie, then put it in shaping mould, inject concrete, matched moulds, hale the arm-tie that rises to set pressure, centrifugally make stake, obtain prestressing force prefabricated component.Above-mentioned patent structure is mainly used in the shaping of more piece stake and connection connects, and is not suitable for the manufacture of single-unit stake, does not have versatility; Secondly, because the structure of haling nut is unreasonable, directly impact is to its tensile strength, has the stealthy phenomenon of rupture haling nut.
Summary of the invention
Purpose of design: on the basis of background technology, design one was both haled without the need to end plate, and the concrete tubular pile that can realize again haling reinforcing bar is general hales nut and reinforcing bar.
Design scheme: in order to realize above-mentioned purpose of design.The present invention is in structure design: the design of 1, haling the suitable for reading and end opening difference flare in heading hole bottom nut chamber is one of technical characteristic of the present invention.The object done like this is: owing to haling the suitable for reading in horn mouth of heading hole bottom nut chamber, its horn mouth is less than or equal to 45 degree along the angle α of inclined-plane and horizontal plane, test proves: when to hale bottom nut chamber heading hole horn mouth is less than or equal to 45 degree along the angle α of inclined-plane and horizontal plane time, it hales nut can either bear the power of haling rod iron and producing, can effectively avoid again haling the generation that reinforcing bar pulls phenomenon, fundamentally solve the generation of haling heading clamping platform phenomenon of rupture bottom nut of haling reinforcing bar and causing simultaneously, the intensity of haling daybreak cap tensile reinforcement is improved widely.2, haling along the design that the angle of inclined-plane and horizontal plane is greater than 90 degree on nut end opening, is technical characteristic two of the present invention.The object done like this is: when hale nut end opening is greater than 90 degree along the angle of inclined-plane and horizontal plane time, can greatly improve rod iron percent of pass, be convenient to passing rapidly through of reinforcing bar, not only effectively improve operating efficiency, and fundamentally solve reinforcing bar and wear the defect being biased to and haling outside nut.3, the inclined-plane in the heading of reinforcing bar two ends in inclined-plane cylinder with hale nut suitable for reading on the design that matches along inclined-plane, be technical characteristic three of the present invention.The object done like this is: one is because reinforcing bar end upset is made up of cylinder and interior inclined-plane cylinder, and the circumferential slopes that in rod iron heading, the circumferential slopes of inclined-plane cylinder is suitable for reading with haling nut is coincide when coordinating, the strong pulling force that guarantee produces when haling nut by hale nut heading inner periphery ramp effect on reinforcing bar end upset and make reinforcing bar hale uniform force by rod iron heading, hale after rod iron extend balanced, degradation defect under phenomenon of rupture can not being haled and haling rod iron intensity that rod iron unbalance stress causes; Two be only have when the circumferential slopes of inclined-plane cylinder in the reinforcing bar end upset circumferential slopes suitable for reading with haling nut coincide coordinate time, can not occur when guarantee hales nut due to the stressed irregular and generation of haling nut fractures phenomenon that causes.4, haling heading hole length and degree of depth sum suitable for reading bottom nut chamber and be greater than the design of 30mm, is technical characteristic four of the present invention.The object done like this is: finding in repetition test many times, only have when haling that bottom nut chamber, heading hole length and degree of depth sum suitable for reading are greater than 30mm, could meet and bear single-unit stake when haling heading hole bottom nut chamber and hale power needed for rod iron, otherwise will be directed at and hale nut and hale damage, or after haling stake processed, hale the generation of nut at prefabricated tubular pile internal fissure or phenomenon of rupture, cause single-unit pile mounted mass decline or scrap.5, the cap mouth haling nut is bell-mouthed design, is technical characteristic five of the present invention.The object done like this is: can guarantee multiplely to hale bolt and hale nut and dock accurate, disposable putting in place, avoids the defect that work efficiency that repeatedly docking causes is low.
Technical scheme: a kind of concrete tubular pile and component is general hales nut and reinforcing bar, hales the suitable for reading and end opening flare respectively in heading hole bottom nut chamber.
The present invention is compared with background technology, hale the design of the further improvement of nut structure, the needs that reinforcing bar, connection are haled in more piece stake can either be met, the needs that rod iron is haled in single-unit stake can be met again, and make the bearing capacity haling nut obtain the raising of essence, avoid and hale the generation that nut hales phenomenon of rupture, particularly solve the generation of recessive phenomenon of rupture after haling nut stake, ensure that the Forming Quality of single-unit stake.
