Description
Technical field:
The utility model relates to a kind of pile tube and connects button, precast plate and connect 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 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, 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 expansion hanging volume expansion of setscrew is in chamber 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 double-end expansion hanging pile extension button and the prefabricated component thereof with quick grafting expansion pile extension; The 2nd, realizing rises draws nut and top to draw the integrated of nut structure, 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 expansion principle to force the double-end expansion hanging body between the pile tube that needs pile extension to form the butt joint of expanding in moment in first to file.On structure design: 1, the design of drawing nut of rising is one of feature of the present utility model, and its major function is: the one, and rise and draw screw thread in the nut to rise to hale 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 firmly to rise and draw in the nut; The 3rd, rise and draw the design of nut lumen, the particularly design of pawl engaging structure in the chamber can form the hook drawknot with expansion hanging body in the double end varicosity and close-----------by the pin that expands can moment with the expansion hanging volume expansion in the double-end expansion hanging body in the chamber of drawing nut of rising and form hook and draw engaging structure.2, the design of double-end expansion hanging body is two of a feature of the present utility model, its major function is: the one, and the expansion hanging body in the double-end expansion hanging body (the particularly boss on the expansion hanging body) can draw that the inner convex platform of instantaneous expansion distortion and expansion chamber forms engagement in the chamber in the nut rising after being subjected to the inserting by force of its pin that expands, and the expansion hanging body after the dilatancy can be locked in the chamber firmly; The 2nd, the expansion hanging body at two ends can be realized expansion hanging respectively with under the effect of the pin that expands in insertion moment of drawing the nut lumen of rising in the double-end expansion hanging body, thereby docking with mode moment of expansion hanging between pile tube and pile tube can be finished.The bloated pin that the double-end expansion hanging volume expansion articulates end of body be the expansion hanging body be able to that instantaneous expansion struts basic, it is similar to, and taper-----point is gone up thick down, after inserting the expansion hanging body, the expansion hanging body can be strutted, produces permanent deformation, permanent locking in the chamber of nut is drawn on the top along its guiding wire casing moment of expanding.
Technical scheme 1: double-end expansion hanging pile extension button rises by two and draws nut (1), double-end expansion hanging body (4) and the pin (7) that expands to constitute, during butt joint, the expansion hanging body of double-end expansion hanging body (4) rises at two at expansion hanging under the effect of the pin (7) that expands and draws in the expansion hanging chamber (11) in the nut (1) and articulate with boss (8) in the chamber.
Technical scheme 2: the prefabricated component that constitutes by double-end expansion hanging pile extension button, prefabricated component (12) two ends are equipped with respectively to rise draws nut (1), the heading (10) at the two ends of some longitudinal reinforcements is connected to respectively to rise and draws on the reinforcing bar heading Ka Tai (2) in the nut (1) in the prefabricated component (12), and double-end expansion hanging body (4) and expanding is sold (7) and is used for butt joint between two prefabricated components (12).
Technical scheme 3: prefabricated component that constitutes by double-end expansion hanging pile extension button and the docking structure between prefabricated component, the end of two prefabricated components that dock is equipped with several respectively and rises and draw nut, rise and draw the heading clamping at longitudinal reinforcement two ends in the reinforcing cage in nut and the prefabricated component, the double-end expansion hanging body draws in the chamber of nut rising by the pin expansion hanging that expands respectively, finishes docking between prefabricated component and prefabricated component.
Technical scheme 4: the preparation method of making prefabricated component by double-end expansion hanging pile extension button, the heading at the two ends of some longitudinal reinforcements is stuck in to rise and draws the heading Ka Tai in the nut to go 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 and draw the prefabricated component of expansion nut structure, the double-end expansion hanging body and the pin that expands are used for two butt joints between prefabricated component.
The utility model is compared 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 rapid abutting joint pile extension between prefabricated component and prefabricated component and the reliability height that docks, high efficiency.
