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 inserting elastic meshing body pile extension button and the prefabricated component thereof with quick grafting expansion pile extension; The 2nd, realization is risen to draw nut and rise and is drawn 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 engaging tooth 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 expansion 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 expansion 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 expansion nut; The 3rd, rise and draw the design of expansion chamber in the expansion nut, the particularly design of plug-in type shifter collar inboard pawl engaging structure in the expansion chamber can form the hook drawknot and close, and----------inserts the plug-in type shifter collar inboard in the suitable tooth that can moment double end be meshed denticle two and the expansion chamber that draws expansion nut that rises by elasticity pawl formation hook draws engagement with the suitable toothing at two in the double end varicosity.2, the design of double end engagement denticle is two of a feature of the present invention, its major function is: the one, the tooth at two in the double end engagement denticle (along tooth engaging conformation) elasticity insert rise draw plug-in type shifter collar in the expansion nut after, can form engagement with the pawl wall of plug-in type shifter collar inboard, being locked in firmly rises draws in the expansion chamber of nut; The 2nd, the engaging tooth at two ends rises to draw in the plug-in type shifter collar in the expansion nut expansion chamber in insertion and can realize the Elastic Meshing butt joint moment in the double end engagement denticle, makes docking between pile tube and pile tube insert the mode that is connected with a joggle with elasticity and finishes.
Technical scheme 1: double-end inserting elastic meshing body pile extension button, plug-in type shifter collar (8) is positioned at the expansion chamber (6) that rises and draw nut (1), plug-in type shifter collar (8) outside and rise to draw between expansion nut (1) wall and be equipped with spring (2), during butt joint, double end engagement denticle (3) inserts between plug-in type shifter collar (8) and under the effect of spring (2), double end engagement denticle (3) and plug-in type shifter collar (8) engagement.
Technical scheme 2: the prefabricated component that constitutes by double-end inserting elastic meshing body pile extension button, prefabricated component (10) two ends are equipped with a plurality of rising respectively and draw expansion 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 expansion nut (1) in the prefabricated component (10), and double end engagement denticle (3) is used for the butt joint between two prefabricated components (10).
Technical scheme 3: prefabricated component that constitutes by double-end inserting elastic meshing body pile extension button and the docking structure between prefabricated component, the end of two prefabricated components that dock is equipped with a plurality of rising respectively and draws expansion nut, a plurality of rising on the one prefabricated component end draws the expansion nut mouth to draw the expansion nut mouth relative with a plurality of the rising on another prefabricated component end, double end engagement denticle inserts respectively to rise and draws in the plug-in type shifter collar in the expansion nut and form Elastic Meshing with tooth in the plug-in type shifter collar, finishes docking between prefabricated component and prefabricated component.
Technical scheme 4: the preparation method of the prefabricated component that constitutes by double-end inserting elastic meshing body pile extension button, the two ends of some longitudinal reinforcements are upset into heading and heading and are stuck in just to rise and draw on the heading Ka Tai in the expansion nut in the reinforcing cage, to have rises draws the expansion nut reinforcing cage to put into shaping mould, 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.
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; The 3rd, double-end expansion meshing-body and rising draws in the nut that the expansion hook drawknot that forms closes between the expansion shifter collar in the expansion chamber, has guaranteed the reliable connection between pile tube and pile tube; The 4th, solved the problem that some longitudinal reinforcements in the pile tube can't the standardization longitudinal extension, realized the uniformity of pile tube intensity, pile tube inherent quality; The 5th, reduced the cost of production of pile tube widely, only remove one of tubular pile head end plate, only domestic annual demand is saved about 30 yuan of cost for every more than 100,000,000, can produce unexpected economic benefit and social benefit every year for saving RMB more than 3,000,000,000 yuan; The 6th, start made between pile tube and pile tube, the novel docking structure between precast plate and precast plate, between bridge pier and bridge pier, between electric pole preform rod and preform rod.Be to rise to draw the design of expansion nut and end plate welding connection structure, not only guaranteeing rises draw expansion 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 expansion nut of rising, avoid impact force to concentrate, easily cause the deficiency of pile tube breakage.
