Using method of positioning device capable of adjusting prefabricated column connecting steel bars in three directions

Abstract

The invention discloses a using method of a positioning device capable of adjusting prefabricated column connecting steel bars in three directions. The positioning device comprises a positioning plate and a sleeve penetrating through the positioning plate, a first leveling bubble and a first laser assembly are fixed to the positioning plate in the transverse axis direction, and a second leveling bubble and a second laser assembly are fixed to the positioning plate in the longitudinal axis direction. The using method comprises the steps that S1, the connecting steel bars on a prefabricated reinforced concrete column are inserted into the sleeve; S2, according to the first leveling bubble and the first laser assembly, the deviation degree of the connecting steel bars in the transverse axis direction of the positioning plate is adjusted, and according to the second leveling bubble and the second laser assembly, the deviation degree of the connecting steel bars in the longitudinal axis direction of the positioning plate is adjusted; and S3, when the connecting steel bars are coaxially aligned with the sleeve in the vertical direction, positioning alignment of the positioning plate and the prefabricated reinforced concrete column is completed. The deviation of the perpendicularity of the connecting steel bars can be detected and adjusted from three directions, and the hoisting precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of construction tools, in particular to a method for using a three-way adjustable prefabricated column connecting steel bar positioning device. Background technique [0002] The prefabricated integral frame structure is prefabricated with vertical load-bearing components. The verticality of the connecting steel bars at the top of the precast concrete columns determines whether the upper precast columns can be hoisted smoothly, and the horizontal and vertical accuracy of the connecting steel bars at the top of the precast reinforced concrete columns determines the horizontal plane. The installation accuracy of the upper prefabricated columns. The current conventional construction methods have many disadvantages, the specific analysis is as follows: [0003] (1) The uppermost layer of barbeque rack vertical steel bars connected to the top of the prefabricated column cannot effectively limit the deviation of t...

Problems solved by technology

[0003] (1) The uppermost barbeque frame vertical steel bar on the top of the prefabricated column can not effectively limit the deviation of the verticality of the connected steel bar, let alone solve the practical problem of the deviation of the connected steel bar; Ensure that the connecting steel bars on the same axis are on the same straight line, so that it cannot effectively detect whether the upper precast column is aligned with the connecting steel bar on the top of the precast concrete column in two horizontal directions, which reduces the hoisting accuracy;

[0004] (2) The error of the verticality of the connecting steel bars is small, but it is easy to have verticality deviations during the unloading and hoisting process on site and when the steel bars at the beam-column joints are tied. At the same time, the horizontal and vertical errors of the horizontal plane will also be Affects the smoothness of prefabricated column hoisting, and the hoisting efficiency is low
