Hoisting elevation and verticality adjusting device for prefabricated concrete structural column and construction method thereof

Abstract

The invention relates to the technical field of assembly of prefabricated concrete structures, in particular to a hoisting elevation and verticality adjusting device for a prefabricated concrete structural column and a construction method thereof. The hoisting elevation and verticality adjusting device comprises a horizontal positioning iron ring used for being connected with a beam longitudinal bar of a joint core area cast-in-place part of a prefabricated concrete structure, the positioning iron ring is triangular or quadrangular, the ends of all inner corners of the positioning iron ring are provided with adjusting sets respectively, and embedded parts for abutting against the upper ends of the adjusting sets are correspondingly embedded in column heads located at the lower end of a prefabricated upper column. The device is compact in structure and facilitates the adjustment of the hoisting elevation and verticality of the prefabricated concrete structure, and the construction method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of assembly of a prefabricated concrete structure, in particular to a device for adjusting the hoisting elevation and verticality of a prefabricated concrete structure column and a construction method thereof. Background technique [0002] In recent years, the prefabricated frame structure has been vigorously developed and applied because of its advantages such as good construction quality, short construction period, low labor intensity, standardized production in factories, conducive to environmental protection and socialized production development. . The assembly of prefabricated concrete structures requires precise elevation and verticality of beams and columns. When hoisting the column of the prefabricated concrete structure, it is necessary to set two oblique supports on the two vertical surfaces perpendicular to the column to form a K-shaped support, which is used to control the verticality of the col...

AI Technical Summary

Problems solved by technology

When manually setting pads, since the surface of the cast-in-place concrete is difficult to ensure that it is horizontal and the surface of the lower end of the precast column is roughened, the elevation and verticality of the precast upper column cannot be guaranteed, and there may even be a large error accumulation, resulting in prefabricated The problem that the components cannot be installed; the verticality of the column is controlled by the K-shaped support, often causing only one pad to support the upper precast column and the lower cast-in-place concrete, and the rest of the pad does not play a role, resulting in the stability of the precast column Poor performance, which can easily cause construction safety hazards
