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 expansion 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 meshing-body 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 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 invention, 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 expansion chamber in the nut, the particularly design of pawl engaging structure in the expansion chamber can form the hook drawknot and close, and----------can be expanded the expander in the double-end expansion body in the expansion chamber that draws nut that rises and form hook by the pin that expands and draw engaging structure moment with the expander in the double end varicosity.2, the design of double-end expansion body is two of a feature of the present invention, its major function is: the one, and the expander in the double-end expansion body (the particularly suitable tooth engaging conformation on the expander) can draw the expand pawl wall in chamber of instantaneous expansion distortion and chamber in the expansion chamber in the nut to form engagement rising after being subjected to the inserting by force of its pin that expands, and the expander after the dilatancy can be locked in the expansion chamber firmly; The 2nd, the expander at two ends can be realized the butt joint of expanding respectively with under the effect of the pin that expands in insertion moment of drawing expansion chamber in the nut of rising in the double-end expansion body, thereby can be with docking with expansion ways of connecting permanent finishing of moment between pile tube and pile tube.The bloated pin of double-end expansion volume expansion end of body be expander be able to that instantaneous expansion struts basic, it is similar to, and taper-----point is gone up thick down, after inserting expander, expander can be strutted, produces permanent deformation, permanent locking in the expansion chamber of nut is drawn on the top along its guiding wire casing moment of expanding.
Technical scheme 1: double-end expansion meshing-body pile extension button rises by two and draws nut (1), double-end expansion meshing-body (3) and the pin (2) that expands to constitute, during butt joint, the expander of double-end expansion meshing-body (3) expands down to rise to draw in the expansion chamber (6) in the nut (1) and with the engaging tooth expansion of expansion chamber wall at two in the effect of the pin (2) that expands and meshes.
Technical scheme 2: the prefabricated component that constitutes by double-end expansion meshing-body pile extension button, prefabricated component (10) two ends are equipped with respectively to rise draws nut (1), the heading (11) at the two ends of some longitudinal reinforcements is connected to respectively to rise and draws on the reinforcing bar heading Ka Tai (5) in the nut (1) in the prefabricated component (10), and double-end expansion meshing-body (3) and expanding is sold (2) and is used for butt joint between two prefabricated components (10).
Technical scheme 3: prefabricated component that constitutes by double-end expansion meshing-body 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 to draw the nut mouth and rise and draw the nut mouth relative, double-end expansion meshing-body expands by the pin that expands respectively and draws in the expansion chamber of nut rising, and finishes docking between prefabricated component and prefabricated component.
Technical scheme 4: the preparation method of making prefabricated component by double-end expansion meshing-body pile extension button, the heading at the two ends of some longitudinal reinforcements is stuck in two and rises and draw 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 meshing-body and the pin that expands are 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, high efficiency.
