Abstract

The invention discloses an installation and vertical gap-adjusting method for crank arm beams of a self-lifting outrigger rollover system of a bridge pier stud, and the installation error between the crank arm beams and strengthening horizontal back ribs can be adjusted. The gap-adjusting method comprises the steps of 1, installing second lock nuts on the cap nut ends of adjusting bolts, the adjusting bolts penetrating a strengthening horizontal back rib, and installing second gap-adjusting nuts when the threaded ends are positioned between two adjacent strengthening horizontal back ribs; 2, when the threaded ends of the adjusting bolts penetrating vertical through holes in the crank arm beams; 3, installing first gap-adjusting nuts on the threaded ends, the threaded ends penetrating another strengthening horizontal back rib, and installing first lock nuts on the threaded ends; 4, tightening the first gap-adjusting nuts and the second gap-adjusting nuts; and 5, adjusting the first lock nuts and the second lock nuts to make the adjusting bolts to move up and down, to adjust the positions of the crank arm beams, and tightening the first lock nuts and the second lock nuts to lock the adjusting bolts. The installation efficiency can be improved by adopting the gap-adjusting method.

Description

technical field [0001] The invention relates to a vertical position adjustment method, in particular to a vertical distance adjustment method for the installation of a curved arm beam of a self-elevating outer frame turning system of a bridge pier column. Background technique [0002] The self-elevating outer frame turning system of bridge pier columns is composed of formwork system, outer support system, formwork disassembly system, lifting system, fall prevention system, operating platform system, etc., and each system is arranged in the space formed by the formwork and the support behind the formwork Inside. [0003] Such as figure 1 As shown, the outer support system is composed of a vertical guide beam, a curved arm beam 1, a reinforced horizontal back corrugated 3, and a straight beam 5. The curved arm beam 1, the reinforced horizontal back corrugated 3, and the straight beam 5 form a closed beam on the plane, and the components of the closed beam form a hoop-type ho...
