Description

Technical Field

[0001] This utility model belongs to the field of engineering construction equipment design technology, and in particular relates to a split casting mold for bridge guard plate columns. Background Technology

[0002] Bridge guardrail columns mainly consist of crossbeams, columns, and guardrail structures. Currently, bridge guardrail columns are typically designed as an integrated structure, including horizontal and vertical concrete casting molds. Due to the differences in the dimensions of the columns, crossbeams, and guardrails, construction sites often face challenges because the materials of the guardrails, crossbeams, and columns are inconsistent. Vertical molds cannot be used for casting materials separately; while conventional horizontal molds require casting the guardrail first, and then casting the columns and crossbeams after the guardrails have reached a certain strength. Finally, the front surfaces of the columns and crossbeams require manual finishing. Therefore, bridge guardrail columns cast using existing molds and construction methods suffer from poor appearance quality, large dimensional deviations, and low construction efficiency. Summary of the Invention

The bottom mold for the beam and column is fixed on the base. The side molds for the column and the side molds for the beam are installed on the bottom mold to form a casting groove for the beam and column. The end molds for the column and the end molds for the beam are respectively set at the ends of the column and the beam. The molds are connected by bolts to form a whole.

[0007] The protective plate mold includes a base, a bottom protective plate mold, and side protective plate molds. The bottom protective plate mold is fixed on the base. Multiple sets of side protective plate molds are connected to the bottom protective plate mold via a rotating shaft to form an openable and closeable mold. When the side protective plate molds are closed, they are connected and fixed by bolts to form a protective plate casting groove. Positioning clips for positioning the horizontal beam and column casting components are set on the upper edge of the side protective plate mold.

[0008] Furthermore, the base of the beam and column mold and the base of the guard plate mold both include multiple support beams fixedly installed on the ground.

[0009] Furthermore, the beam side mold, column side mold, and beam / column bottom mold are connected and fixed by bolts. The beam / column bottom mold is provided with a limiting groove for connecting with the beam side mold.

[0023] Step 5: Rotate the entire guardrail post 180°;

[0024] Concrete pouring for protective slabs:

[0025] Step 1: Clean all templates, rotate the side molds of the protective plate around the rotating axis in sequence, tighten all bolts on the side molds of the protective plate, and spray release agent;

[0026] Step 2: Roughen the contact surface between the cast and solidified beams and columns and the protective plate, and connect the steel bars of the protective plate to the steel bars of the beams and columns.

[0027] Step 3: Hoist the crossbeam column onto the protective plate mold, use the limit clips and bolts installed in the crossbeam column sleeve to accurately position the crossbeam column, and then pour and cure the protective plate concrete.

[0028] Alternatively, the concrete for the protective plate can be poured first on the protective plate mold, and then the crossbeam and column can be hoisted onto the protective plate mold for precise positioning, followed by concrete pouring and curing.

[0029] Step 4: Remove and demold the concrete when it meets the demolding requirements.
