Problems solved by technology

[0003] In the butt welding process of arch beams, since the long arch beams are basically large H-shaped steel, the thickness of the flange plate and the web plate is large, the uneven temperature changes caused by multi-layer and multi-pass welding during the butt welding process will cause Cause twisting and deformation of long arch beams and out-of-tolerance pre-camber value

Abstract

The invention relates to a large arched beam on-site splicing construction deformation detection and measurement device and a use method thereof. The device comprises a rack used for installing each part, and a jack fixing assembly which is used for fixing a jack, wherein the jack fixing assembly is arranged on the rack, and the jack is arranged on the jack fixing assembly; a fixed supporting assembly is used for supporting the bottom of a large arched beam; the fixed supporting assembly is arranged on the jack; a deformation detection steel wire erecting assembly is used for erecting a deformation detection steel wire; and the deformation detection steel wire erecting assembly is arranged on the rack. According to the large arched beam on-site splicing construction deformation detection and measurement device and the use method thereof, the on-site large arched beam splicing quality can be improved, and the related installation requirements of large arched beams are met.

Description

technical field [0001] The invention belongs to the technical field of heavy arched beams, and in particular relates to a deformation detection and measurement device for on-site splicing construction of heavy arched beams and a method for using the same. Background technique [0002] In power plants, metallurgy and other industries, it is often necessary to use heavy-duty long arch beams such as boiler large plate beams and cooling bed crane beams to support steam drums, cranes and other related heavy equipment. The production of these beams will be prefabricated in sections in the processing plant, transport After arriving at the site, these segmental arch beams are spliced ​​and arched. After splicing, the amount of distortion and pre-camber must meet the relevant specifications. [0003] In the butt welding process of arch beams, since the long arch beams are basically large H-shaped steel, the thickness of the flange plate and the web plate is large, the uneven temperat...
