An assembled pier rapid connection structure for an assembled construction technique of a pier, and more particularly, to a technique for rapidly installing a pier on a cap.
This assembled pier quick connect structure, particularly, pier in this technique is reinforced concrete prefabricated part, adopts engineering prefabrication shaping, transports to the job site and carries out the assembled construction operation.
A cast-in-place bearing platform is arranged right below the bridge pier, and the cast-in-place bearing platform is a cast-in-place structure of a steel-concrete structure.
Referring to fig. 1 to 6, near the mating surfaces of a pier 10 and a cap 20, a notch 11 having a U-shaped cross section is provided along a vertical direction, and nut fastening grooves are provided at upper and lower ends of the notch.
The U-shaped notch 11 is a U-shaped metal embedded part 30 embedded in the pier and the abutment to form a bolt placing passage.
The metal embedded part 30 is formed by bending a steel plate with a thickness of 2 mm, and has a U-shaped profile in cross section formed by two lug plates and a bent portion.
A notch 31 is milled in the top of the metal embedded part 30, the notch formed by so-called milling exists in the bending part 32 and does not completely cover the lug plate part 33, and a flanging is formed outwards at the lug plate part 33 which is completely covered by the milling, and the flanging is used for matching with the embedded box.
The embedded box 40 is an injection-molded engineering plastic part and is arranged at the corresponding parts of the pier and the bearing platform, particularly, the embedded box 40 is embedded when commercial concrete is poured, and is integrated with the pier and the bearing platform after being demolded. The embedded box is a square box with an outward opening and is provided with a clamping groove, and the clamping groove is a U-shaped clamping groove.
The metal embedded parts 30 and the embedded boxes 40 are in clamping fit to form a whole, that is, one embedded metal part corresponds to one embedded box. The pier above and the embedded metal parts in the bearing platform below are in one-to-one correspondence.
And forming multi-point connection at the matching surface between the pier and the bearing platform, wherein the plurality of connection points are uniformly distributed along the circumferential direction.
A plurality of sets of bolt assemblies 50 are also included. The bolt assembly is a stud bolt and comprises a screw rod, a gasket and a nut, wherein each set of bolt assembly comprises an upper nut, an upper gasket, a screw rod, a lower gasket and a lower nut. Wherein the screw rod is carved with a thread with a certain depth; the outer side profiles of the upper nut and the lower nut are hexagons, and the inner profiles are provided with threads matched with the screw rod, so that the upper nut and the lower nut can be reliably connected with the screw rod. The outer diameters of the upper gasket and the lower gasket are respectively larger than the diameters of the circumscribed circles of the upper nut and the lower nut, the inner diameters of the upper gasket and the lower gasket are larger than the diameter of the screw rod, but the outer diameters of the circumscribed circles of the upper nut and the lower nut are smaller than the diameter of the circumscribed circle of the upper nut and the diameter of the circumscribed circle of the lower nut, and therefore the connecting device and the assembling structure can be effectively connected into a whole.
Further improvement, the mating surfaces of the pier 10 and the abutment 20 are annular stepped mating surfaces, which is advantageous for maintaining high torque.
