Abstract

The invention provides a hollow pier prefabricated inter-segment connecting device and a construction method thereof.The connecting device comprises embedded steel plates, U-shaped steel bars, rubberplates, upper / lower connecting steel plates, upper / lower shear-resistant steel plates and filling plates, the embedded steel plates are embedded in the inner surfaces of prefabricated segments, the U-shaped steel bars are welded to the embedded steel plates, parts of the U-shaped steel bars extend into the prefabricated segments, and parts extend out of the embedded steel plates; threads are arranged on the extending portions, and the rubber plate, the upper connecting steel plate and the lower connecting steel plate are connected with the embedded steel plate through connecting bolts. And after the upper prefabricated segment and the lower prefabricated segment are assembled, the upper shear-resistant steel plate is connected with the upper connecting steel plate through high-strength bolts, the lower shear-resistant steel plate is connected with the lower connecting steel plate through high-strength bolts, filling plates are plugged between the upper shear-resistant steel plate and the lower shear-resistant steel plate, and the upper shear-resistant steel plate is connected with the lower shear-resistant steel plate through high-strength bolts. The connecting device disclosed bythe invention meets the requirements of different procedures in the assembling process of the prefabricated sections, and realizes the functions of hoisting, section position positioning, section linear adjustment, section glue joint prepressing, temporary locking and the like.

Description

technical field [0001] The invention relates to the technical field of bridge structure construction, in particular to a hollow pier prefabricated inter-segment connection device and a construction method. Background technique [0002] In the field of prefabricated assembled construction, prefabricated assembled hollow piers are widely used in highway, municipal and some sea-crossing projects. Compared with traditional cast-in-place construction, it eliminates the need for on-site binding steel bars, building and dismantling formwork, and pouring concrete. The on-site workload has accelerated the construction speed and improved the project quality. [0003] The prefabricated assembled hollow pier is composed of different prefabricated segments. The prefabricated segments are manufactured in the factory and then transported to the site for assembly. The assembly process is the core construction link. The quality of the assembly construction is directly related to the alignmen...
