Description
Technical field
The present invention relates to a kind of bull fast tearing to clasp and interfacing part, and the prefabricated component that clasp is constituted by the bull fast tearing, and the docking structure between prefabricated component and prefabricated component, belong to that prefabricated component is haled fastener and prefabricated component is made the field.
Background technology
All notice of authorization CN100348803C of this patent people, title " go up apical grafting stake button and prefabricated component under the spiral shell ", this pile for prestressed pipe reinforcing bar is haled fastener, draw nut, top to draw nut and pile tube longitudinal reinforcement to form by being positioned at rising of pile tube two ends, wherein, rising, to draw nut and top to draw nut be female thread structure, and described internal thread is for haling screw thread, and the center has reinforced hole at the bottom of the cap, the periphery of reinforced hole is reinforcing bar heading Ka Tai, and the two ends of pile tube longitudinal reinforcement are upset into heading and are connected on the Ka Tai.
This pile for prestressed pipe pile extension button draws nut, top to draw nut, combination sleeve, intermediate sleeve and connecting rod to constitute by rising, wherein, rising, to draw nut and top to draw nut be female thread structure, described internal thread is for haling screw thread, the center has reinforced hole at the bottom of the cap, the periphery of reinforced hole is reinforcing bar heading Ka Tai, and the two ends of pile tube longitudinal reinforcement are upset into heading and are connected on the Ka Tai; Connecting rod one end is a dentalation, and the other end is an external thread structure; Two or multi-disc combination sleeve is positioned at the top and draws nut, described combination sleeve inboard to be dentalation and be complementary with dentalation in the connecting rod; Intermediate sleeve is an external thread structure, is screwed in the top and draws in the nut and be positioned at two or multi-disc combination sleeve top; During butt joint, connecting rod one end draws the screw thread of nut to spin with rising, and the other end and top draw in the nut two or multi-disc combination sleeve to form clamping.
Docking calculation between this prestressing force prefabricated component, the end of two prefabricated components that dock be respectively equipped with several rise draw nut and and with it corresponding several tops draw nut, two or multi-disc combination sleeve is positioned at the top and draws nut, intermediate sleeve is screwed in the top and draws in the nut and be positioned on two or the multi-disc combination sleeve, connecting rod one end with rise draw that nut spins, the other end and top draw two or multi-disc combination sleeve formation clamping in the nut.
Its objective reality reality is: in existing examination criteria, what detect is Stress Transfer, and in the background technology butt joint after pile tube be pressed into underground after, because reinforcing bar (rod) heading and hale the loose contact that might have minute quantity between the connecting rod in the fastener between pile tube and the pile tube, though this loose contact, belong within the scope of reliable butt joint, pile tube is not produced any influence with the quality of docking between the pile tube, but because the pile tube after the butt joint has been pressed into underground, with the standard and the detection method of existing detection can't be supporting, though it is qualified the result who detects by current standard of minute quantity therefore to have occurred, unfavorable result.
Summary of the invention
Purpose of the present invention is avoided the weak point in the background technology, designs between a kind of prefabricated component and prefabricated component that can either satisfy after reinforcing bar haled reliably to dock, and the bull fast tearing that can satisfy existing pile tube butt joint examination criteria again is to clasp and prefabricated component.
In order to realize one of purpose of the present invention.On structure design, can reinforcing bar be realized effectively haling in the concrete precast element, is the prerequisite that is related to concrete precast element quality quality, and the haling to be divided into and fixedly hale maintenance typing and location and hale displacement maintenance typing of reinforcing bar.Floor prefabricated component and bridge prefabrication spare etc. are fixedly to hale the maintenance typing; Concrete tubular pile, concrete wire then belong to the location and hale displacement maintenance typing.The key that displacement maintenance typing is haled in the location is: not only realize haling of reinforcing bar (rod iron), and will realize good butt joint the between prefabricated component and prefabricated component.Therefore on structure design, fast tearing should have two kinds of functions to clasp: the one, and every group of (two) fast tearing can be realized clamping with reinforcing bar (rod iron) two ends respectively to clasp; The 2nd, the reinforcing bar (rod iron) that haling fastener and haling between the fastener after the butt joint haled is realized Stress Transfer by the fastener of haling of self, goes into the examination criteria on ground with butt joint, the piling of satisfying existing pile tube.
