Embodiment Construction

[0027] Such as Figure 1 to Figure 2 Shown, a kind of cover beam of the present invention can quickly adjust the construction method of support, and this construction method is carried out according to the following steps successively:

[0028] (1) Hoop installation: The hoop installation is to calculate the hoop installation elevation on the circular pier 6 according to the height of the cover beam, and install the hoop 5 designed by force calculation on the specified elevation after measuring with the level instrument. A white geotextile is installed between the hoop 5 and the pier column 6 to enhance the friction between the hoop 5 and the pier column 6 and to protect the appearance of the pier column. The hoop connection bolts are high-strength bolts, and the torque wrench is used to verify the tightening of the bolts. After the bolts have been used for a period of time, check the condition of the bolt wires in time, and replace the bolts in time if they are found to be de...

Abstract

The invention discloses a quickly adjustable bracket for a cap beam and a construction method of the quickly adjustable bracket for the cap beam. The construction method comprises the following steps: (1) hoop installation; (2) mechanical jack installation; (3) beam installation; (4) stringer installation; (5) bottom template installation; (6) steel bar banding; (7) side template installation; (8) concrete pouring; (9) template support disassembly. The quickly adjustable bracket and the construction method thereof provided by the invention have the advantages that the elevation of a bottom template of the bracket can be freely adjusted to the designed position up and down by a mechanical jack, and the mechanical jack cannot retract and slide down; compared with the traditional method that the bracket is dissembled by a wedge block, the construction method is convenient and quick, the time of duration of working procedure is shortened, and the stability and safety of the bracket for the cap beam are improved.

Description

technical field [0001] The invention belongs to the technical field of construction of a cylindrical pier column cover beam of a bridge substructure, and in particular relates to a quickly adjustable support for a cover beam and a construction method thereof. Background technique [0002] With the development of construction projects, the cylindrical pier-column-cap-beam structure has been widely used in bridge construction in our country. According to the current support forms of cover beams, there are methods such as piercing rod method, steel pipe support method, and bowl buckle support method. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a rapidly adjustable support for the cover beam and its construction method, which can adjust the elevation of the bottom mold of the support to the design position within a certain range, and has strong flexibility, high speed The advantages of quick and conven...
