The invention discloses a construction
system and a construction method for a cable-stayed bridge main
tower and steel anchor beams. The construction method for the cable-stayed bridge main
tower andthe steel anchor beams comprises the following steps of step 1, mounting embedded
steel plates and arranging the embedded
steel plates on the top surface of a beam bracket; step 2, arranging a
tower column steel internal template between the top surface of a lower supporting beam and the bottom surface of an upper supporting beam; step 3, mounting the lower part of a steel anchor beam temporary bracket on an existing building platform surface or a finished steel anchor beam top plate; and mounting a steel anchor beam corresponding to the lower supporting beam on the steel anchor beam temporarybracket before segmental concrete pouring of the main tower; and step 4,
welding the steel anchor beam corresponding to the lower supporting beam with the embedded steel plate into place; and then mounting a steel anchor beam corresponding to the upper supporting beam and
welding the steel anchor beam corresponding to the upper supporting beam with the corresponding embedded steel plate. According to the construction method for the cable-stayed bridge main tower and the steel anchor beams, as the mounting construction of the steel anchor beams is integrated into the construction of a tower
column structure, the segmental construction frequency of the tower column is reduced, the method is beneficial for controlling the
internal quality and appearance quality of the tower
column structure,the construction period is reduced and material waste is reduced.
