Embodiment

[0024] Embodiment: As shown in the figure, this embodiment specifically relates to a construction method for quickly aligning holes and adjusting attitude of a prefabricated column. 6 to level the top surface of the cap 11, and during the hoisting process, the pre-embedded sleeve 8 of the prefabricated column 7 is quickly aligned with the pre-embedded steel bar 6 on the hole cap 11 through the self-made guide tapered pliers 3, and then passed The azimuth adjuster 4 adjusts the plane position of the prefabricated column 7, and adjusts the verticality of the prefabricated column 7 by lifting the corbel 9 on the prefabricated column 7. Security Risk.

[0025] Such as Figure 1-6 As shown, a construction method for fast hole and posture adjustment of prefabricated columns in this embodiment includes the following steps:

[0026] (1) The prefabricated column 7 is prefabricated. In the prefabrication stage, a circle of vertical embedded sleeve 8 is embedded at the bottom of the pr...

Abstract

The invention discloses a construction method for rapid hole alignment and posture adjustment of a prefabricated stand column. The method comprises the following steps of lifting the prefabricated stand column to be moved over a bearing platform, vertically arranging a plurality of embedded bars on the top face of the bearing platform, and vertically and correspondingly arranging a plurality of embedded sleeves inside the prefabricated stand column; utilizing a guiding conical clamp for clamping the embedded bars to guide the prefabricated stand column to fall gradually, enabling the embeddedsleeves to be accurately aligned to the embedded steel bars; removing the guiding conical clamp, when the prefabricated stand column falls down to the position, the preset height away from the top face of the bearing platform, utilizing direction regulators installed at the four edges of the top face of the bearing platform for horizontally pushing the prefabricated stand column, and precisely regulating the plane position of the prefabricated stand column so as to enable the prefabricated stand column to accurately fall down to the center of the bearing platform. The method has the advantagesthat in the lifting process, the prefabricated stand column can be rapidly arranged in place, and the trial lifting frequency and time in the lifting process are decreased; in the lifting process, the plane position and perpendicularly of the prefabricated stand column can be conveniently and precisely adjusted, it is ensured that the construction error is controllable, operation is easy, and thesafety risk is low.

Description

technical field [0001] The invention relates to the technical field of bridge prefabricated assembly construction, in particular to a construction method for quickly aligning holes and adjusting postures of prefabricated columns. Background technique [0002] With the promotion and popularization of bridge prefabricated assembly construction technology in bridge construction, a large number of prefabricated columns are required to be hoisted during the construction process. Big. [0003] Traditional columns are mainly cast-in-place, without large-scale and large-tonnage hoisting. In recent years, there have also been a small number of prefabricated and assembled bridge projects, but the hoisting process is cumbersome and inefficient, and the hoisting accuracy of the columns is not well controlled. Contents of the invention [0004] The object of the present invention is to provide a construction method for fast hole alignment and attitude adjustment of prefabricated colu...
