Forming method of high-strength bridge concrete prefabricated part

Abstract

The invention relates to a forming method of a high-strength bridge concrete prefabricated part. A forming device of the high-strength bridge concrete prefabricated part is adopted, and the device comprises a mounting frame, support legs, vibration mechanisms, smoothing mechanisms, vibration sliding rods, telescopic rods, a vibration rack, horizontal rods, vertical rods, inclined rods and a building box. According to the forming device of high-strength bridge concrete prefabricated part disclosed by the invention, the following problems can be solved: in a forming process of the high-strength bridge concrete prefabricated part, the interior of a bridge beam steel structure is difficult to be fully filled with the high-strength concrete, so that the safety and the service life of the bridge concrete prefabricated part are reduced because of formation of a hollow cavity, multi-station synchronous smoothing and compaction operations on concrete residue stones bulged at the bottom and on the side walls of the bridge concrete prefabricated part are difficultly carried out, the labor intensity of surface precision processing for later-period workers is increased, and the operation efficiency of preparation of the high-strength bridge concrete prefabricated part is further reduced.

Description

technical field [0001] The invention relates to the field of concrete prefabricated parts, in particular to a method for forming high-strength bridge concrete prefabricated parts. Background technique [0002] Concrete prefabricated parts refer to concrete products processed and produced in factories through standardized and mechanized methods. Correspondingly, traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated concrete is widely used in construction, transportation, water conservancy and other fields, and plays an important role in the national economy. Bridge concrete prefabricated parts are the structural parts used for the main structure of the bridge during the bridge construction process. Traditional bridge concrete prefabricated parts are usually formed by pouring high-strength concrete into the steel structure frame of the bridge. However, in the process , there are often the following problems: [0...

AI Technical Summary

Problems solved by technology

[0003] 1) Since the overall structure of bridge concrete prefabricated parts is often relatively large, it is difficult to fully fill high-strength concrete into the interior of the bridge steel structure during the high-strength concrete pouring operation, and it is easy to form cavities that cause the safety of bridge concrete prefabricated parts. Decreased performance and service life
