Embodiment 1

[0034] The verticality adjustment structure of the lower beam of the hanging basket is characterized in that: the lower part of the bottom rail longitudinal beam (1) is hinged to the upper pole beam 2 through the ear plate, the rear lower beam 3 and the front lower beam 4 are Bailey beams, and the lower part of the upper pole beam 2 It is respectively fixed with the rear lower crossbeam 3 and the front lower crossbeam 4; the lower part of the rear lower crossbeam 3 and the front lower crossbeam 4 are respectively fixed with the lower pole beam 5, and the lower pole beam 5 and the longitudinal beam 1 of the bottom rail pass through the two ends of the adjustable strut 6 respectively. The lugs are hinged.

[0035] The adjustable strut 6 is composed of an upper threaded rod 61 , a sleeve 62 and a lower threaded rod 63 .

[0036] The rear lower beam 3 is formed by three groups of Bailey beams connected in parallel through the support frame A31, and the front lower beam 4 is formed...

Abstract

The invention provides a hanging basket lower cross beam verticality adjusting structure, wherein the lower portion of a bottom fence longitudinal beam is hinged to an upper carrying pole beam through a lug plate, a rear lower cross beam and a front lower cross beam are bailey beams, and the lower portion of the upper carrying pole beam is fixed to the rear lower cross beam and the front lower cross beam respectively; lower shoulder pole beams are fixed to the lower portions of the rear lower cross beam and the front lower cross beam respectively; the lower shoulder pole beams and the bottom fence longitudinal beams are hinged to the two ends of the adjustable supporting rods through lug plates respectively. Under the condition that the lower cross beam is a bailey beam, the perpendicularity of the lower front cross beam and the lower rear cross beam can be adjusted through the fixing and adjusting effect of the adjustable supporting rod, so that the lower cross beam is prevented from inclining, the stress condition of the lower cross beam is optimized, and the structural safety of the bottom basket of the hanging basket is guaranteed. The structure has the advantages of stable structure and convenient operation.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a structure for adjusting the verticality of the lower beam of a hanging basket. Background technique [0002] The hanging basket is the main equipment for the cantilever pouring construction of long-span prestressed concrete continuous beams. The hanging basket is a load-bearing frame that can slide or roll along the top of the beam. It is anchored and suspended on the constructed beam section, and the next step can be carried out on the hanging basket. Installation of templates, steel bars and prestressed pipes for beam sections, concrete pouring and prestressed tensioning, grouting and other operations. After the cycle of one segment is completed, the hanging basket can be moved forward and fixed for the next segment of cantilever irrigation, and so on until the cantilever perfusion is completed. It has the advantages of light weight, simple structure, solid and s...
