Abstract

The invention provides a splicing adjustment method for a prefabricated bent cap and a prefabricated stand column. The method comprises the steps of marking a first datum line at the corresponding position of a prefabricated bent cap; marking second datum lines on the four surfaces of the installed prefabricated stand column; adjusting the perpendicularity and spacing of the reserved steel bars ofthe installed prefabricated stand column; placing at least three adjusting cushion blocks at the top end of the installed prefabricated stand column, and leveling the at least three adjusting cushionblocks; moving the prefabricated bent cap to the position above the installed prefabricated stand column, and inserting all of the reserved steel bars of the prefabricated stand column into the embedded sleeves of the prefabricated bent cap; and aligning a positioner with the second reference line, adjusting the position of the prefabricated bent cap, and aligning the first reference line with the positioner so as to align the first reference line with the second reference line. The technical problem that leveling and aligning of the prefabricated bent cap and the installed prefabricated stand column are difficult is solved.

Description

technical field [0001] The invention relates to the technical field of splicing adjustment of bridge prefabricated cover beams, in particular to a splicing adjustment method of prefabricated cover beams and prefabricated columns. Background technique [0002] With the rapid development of our country's economy, our country's bridge construction has also developed rapidly. In the process of bridge construction, the splicing construction technology of prefabricated cap beams can significantly shorten the construction period and reduce the construction time. At the same time, it has the advantages of high construction quality, low safety risk and environmental protection. Therefore, prefabricated cap beam splicing construction technology has been widely used in municipal bridge construction. [0003] However, in the splicing construction process of the prefabricated cover beam and the prefabricated column, there is such a problem: the prefabricated cover beam is difficult to l...
