Problems solved by technology

Although the positioning pier can play the role of positioning, it is still very difficult to accurately locate the prefabricated hollow pier, and the positioning method is also completely different from the method in the present invention
[0008] To sum up, with the existing splicing technology, it is necessary to repeatedly adjust the verticality of the prefabricated pier column, which cannot be accurately positioned, which seriously affects the construction efficiency
In addition, most of the existing disclosed technologies are structures in which prefabricated pier columns are connected to caps, and do not involve the precise positioning of prefabricated pier columns during installation

Abstract

The invention discloses a positioning device for installation of a precast pier stud, and the positioning device is applicable to precast pier studs in all structural forms and comprises an annual steel bottom plate arranged outside a precast pier stud, an upper annular sleeve arranged over the annual steel bottom plate as supported by an upper inclined leg, a lower annular sleeve arranged over the annual steel bottom plate as supported by a lower inclined leg, an upper positioner arranged on the upper annular sleeve, and a lower positioner arranged on the lower annular sleeve. The positioning device in the invention is simple to fabricate, quick and convenient to install, and reusable; the perpendicularity of the precast pier stud may be adjusted rapidly for the purpose f accurate positioning; the positioning device is extensive in application range, and suitable for accurate positioning of not only precast solid and hollow pier studs, but also precast pier studs in different section forms. With the positioning device for installation of a precast pier stud, convenient construction and simple and easy operation are achieved with effectively improved construction efficiency of accurate positioning in installation of the precast pier stud and accelerated construction progress.

Description

technical field [0001] The invention belongs to the fields of civil engineering, construction engineering, highway engineering and municipal engineering, and relates to a device for installing and positioning prefabricated piers. Background technique [0002] With the rapid development of construction industrialization, the bridge structure will inevitably enter the industrialization period of rapid assembly. The prefabricated assembly of bridge structure refers to the main components of the bridge structure, including beams, pier columns, cover beams, etc., which are all prefabricated components, and these prefabricated components are assembled through certain connection methods. [0003] During the installation process of the prefabricated pier column, it is necessary to accurately locate the prefabricated pier column so that the components on the upper part of the pier body, such as the cover beam, can be installed smoothly. The key indicator for precise positioning of...
