Abstract

The invention discloses a corrugated steel web positioning method and a bidirectional adjustment and positioning device adopted. The corrugated steel web positioning method includes the following steps: step 1, installing a corrugated steel web bidirectional adjustment and positioning device at the fixed end mold; step 2. Lift the corrugated steel web into the mold according to the design slope; step 3, adjust and position the corrugated steel web in the height direction and transverse bridge direction on the side of the fixed end mold; step 4, on the side opposite to the fixed end mold The matching beam side of the corrugated steel web 1 is adjusted and positioned in the height direction and the transverse bridge direction. The positioning of the invention is convenient and fast, and can reduce the influence of external factors such as wind force, and the positioning is more accurate and reliable.

Description

technical field [0001] The invention belongs to the field of bridges, and in particular relates to a corrugated steel web positioning method and a bidirectional adjustment and positioning device adopted. Background technique [0002] At present, corrugated steel webs are widely used in box bridges. The corrugated steel webs not only greatly reduce the weight of the bridge, but also ensure the structural strength of the bridge. In the construction process of the corrugated steel web in the prior art, the molds including the fixed end mold, the movable end mold, the bottom mold, the side mold and the inner mold are assembled first, and then the corrugated steel web is hoisted. There are some construction methods when positioning Two chain hoists are arranged at the front and rear ends of the corrugated steel web. One end of the chain hoist is connected to the hanging basket hanger, and the other end is connected to the steel web; Horizontal and vertical positioning. At the s...
