Description
Technical field:
The present invention relates to a kind of pile tube connects button, precast plate and connects that button, bridge pier connect button, bridge connects button and electric pole interface and prefabricated component thereof, and adopt pile tube to connect button, precast plate to connect button, bridge pier and connect button, bridge and connect the syndeton between being connected between being connected between being connected between pile tube that button and electric pole interface constitutes and pile tube and pile tube, precast plate and precast plate, bridge pier and bridge pier, electric pole preform rod and preform rod and the preparation method of prefabricated component, the genus prefabricated component connects to be detained and prefabricated component manufacturing field.
Background technology:
The application be 200410091063.9 at all number of patent applications of the applicant, title " goes up apical grafting stake button and prefabricated component under the spiral shell ", draw nut, setscrew and top to draw nut to constitute by rising, rise and draw nut to be screwed in the screw section of setscrew, during butt joint, the expander of setscrew expands in cavity in the nut is drawn on the top.Blemish in an otherwise perfect thing be: the one, need before the butt joint setscrew is screwed in to rise to draw in the screw thread of nut, the pile extension that just can achieve a butt joint then, it is slow therefore to dock pile extension speed; The 2nd, draw nut to draw the structure of nut different owing to rise with the top, so its mfg. moulding die and complex process, and the processing charges height.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, designing a kind of one is peg graft fast bonding pile extension button and grafting pile extension prefabricated component; The 2nd, realization grafting nut draws the integrated of nut structure with the top, reduces mould input and processing charges, reduces production costs.
Design scheme: the application is 200410091063.9 at all number of patent applications of the applicant, invents on the basis that title " goes up apical grafting stake button and prefabricated component under the spiral shell ", be further innovation and realizing on the architecture basics of the applicant, adopt the interference bonding principle of pegging graft to force the double end grafting body moment between the pile tube that needs pile extension to form the bonding butt joint of pegging graft in first to file.On structure design: 1, the design of grafting nut is one of feature of the present invention, and its major function is: the one, and the screw thread in the grafting nut rises hales action of steel bars; The 2nd, have a reinforced hole at the bottom of the cap of nut, the periphery of reinforced hole is reinforcing bar heading Ka Tai, this reinforcing bar heading card platform can be stuck in the reinforcing bar heading that will connect in the grafting nut firmly; The 3rd, the design of cavity in the grafting nut, can moment double end be pegged graft in the cavity that is plugged on the grafting nut behind the grafting body coating adhesive in the body (or in the cavity of grafting nut coating adhesive).2, the design of double end grafting body is two of a feature of the present invention, and its major function is: the one, and the grafting body in the double end grafting body in the cavity in the interference insertion grafting nut, forms whole built-in structure with the grafting nut behind coating adhesive; The 2nd, after the grafting body at two ends inserted cavity in the grafting nut respectively in the double end grafting body, with docking with mode permanent the finishing of moment bonding and that deposit of pegging graft between pile tube and pile tube, the body of forever double end being pegged graft was fixed in the cavity of grafting nut.
Technical scheme 1: plug-in type pile extension end plate is buckled, and two or more grafting nuts (1) are distributed on the end plate (10), and during butt joint, the cavity (6) that double end grafting body (3) inserts respectively in two grafting nuts (1) is interior and firmly affixed with its cavity.
Technical scheme 2: buckle the prefabricated component that constitutes by plug-in type pile extension end plate, prefabricated component is built-in with reinforcing cage, in prefabricated component (2) two ends in the reinforcing cage heading (9) at the two ends of some longitudinal reinforcements respectively with end plate on grafting nut (1) in reinforcing bar heading Ka Tai (5) clamping, double end grafting body (3) is used for docking between prefabricated component and prefabricated component.
Technical scheme 3: buckle the prefabricated component that constitutes and the docking structure between prefabricated component by plug-in type pile extension end plate, the end of two prefabricated components that dock is equipped with the end plate that has several grafting nuts respectively, two of double end grafting body scribbles bonding agent and inserts respectively in the cavity of grafting nut, finishes docking between prefabricated component and prefabricated component.
Technical scheme 4: buckle the preparation method of making prefabricated component by plug-in type pile extension end plate, the heading branch at some longitudinal reinforcement two ends adds the heading Ka Tai that is stuck in the grafting nut that has end plate and goes up and put it in the shaping mould in the reinforcing cage, placing of concrete, matched moulds, hale simultaneously rising of prefabricated component die cavity one end draw expansion nut to the power that sets, force some reinforcing bars to extend to the length that sets synchronously after, centrifugal casting or vibration foundry goods, get promptly that having rises draws the prefabricated component of expansion nut structure, double end grafting body is used for two butt joints between prefabricated component.
The present invention compares with background technology, the one, the structure design uniqueness, simple, processing mold is single, expense is low, reduced cost of production widely; The 2nd, realized the rapid abutting joint pile extension between prefabricated component and prefabricated component, its high efficiency; The 3rd, the design of grafting nut and end plate welding connection structure, not only guaranteeing rises draw nut distribute accurately, be convenient between pile tube and pile tube fast, accurately dock, and can be effectively be delivered to the end face of pile tube equably by its end plate with acting on the power of drawing nut of rising, avoid impact force to concentrate, easily cause the deficiency of pile tube breakage.
