[0010] Furthermore, second positioning holes are symmetrically formed at one end of the first strip-shaped vertical plate and the second strip-shaped vertical plate away from the first positioning hole, and the second horizontal plate is inserted into the second positioning hole.

[0011] Furthermore, two vertical plates are welded on the second horizontal plate at intervals, and the two vertical plates are arranged at the to-be-closed position of the deck to be closed.

[0012] Furthermore, a groove is provided at the joint between the second horizontal plate and the second positioning hole, and the two vertical plates are welded between the first strip vertical plate and the second strip vertical plate.

[0013] Furthermore, a groove is provided on the outer side of the vertical plate, and the second horizontal plate is welded to the groove of the vertical plate.

[0014] A construction method for a steel structure closing mouth reaction force closing device mainly comprises the following steps: S1, the crane hoists the deck piece to be closed into place, aligns it with the main deck in the horizontal direction, and cuts a bevel at the closing mouth to prepare for assembly; S2, place the device on the main deck, and weld the stopper to the hexagonal plate on the main deck; S3, placing a jack between the first strip vertical plate and the second strip vertical plate, welding one end of the jack to the stopper, and using the reaction force to push the first horizontal plate to move away from the stopper; S4, the first horizontal plate drives the second horizontal plate on the first strip vertical plate and the second strip vertical plate to move toward the stopper, thereby completing the assembly and positioning of the main deck and the deck to be closed.
