Single-layer multiple-span bent column crane beam positioning method

Abstract

The invention discloses the single-layer multiple-bay bent crane beam localization. When the crane beam is installed on the bracket of bent side column and bent central column, the distance between central line of crane beam on bracket and scale line of bent side pillar is L1, the distance between central line of crane beam on bracket and scale line of bent central pillar is L2, and the L1 is bigger than L2. The invention adjusts the location dimension between the central lines of crane beam on bent side column and bent central column and span scale line, and the effect of side column caused by single crane load is the same with the effect of central column caused by single crane load. The method has the advantages of homogeneous forcing and low cost.

Description

Technical field: [0001] The invention relates to a positioning and configuration method for a crane beam, in particular to a positioning method for a single-layer multi-span bent column crane beam. technical background: [0002] At present, standard single-story industrial plants that meet the building modulus generally have standard lifting equipment, that is, single-girder cranes or double-girder bridge cranes. Industrial plants with different standard spans are equipped with cranes with corresponding spans. For a factory building with single-story multi-span bent columns, if it is configured according to the standards in the prior art, the distance from the center line of the crane beam installed on the corbels of the bent side columns to the span marking line of the bent side columns The distance is equal to the distance from the center line of the crane girder installed on the corbel of the center column of the bent frame to the span marking line of the center column o...

For a factory building with single-story multi-span bent columns, if it is configured according to the standards in the prior art, the distance from the center line of the crane beam installed on the corbels of the bent side columns to the span marking line of the bent side columns The distance is equal to the distance from the center line of the crane girder installed on the corbel of the center column of the bent frame to the span marking line of the center column of the bent frame. The positioning configuration method with equal marking distances will cause inconsistencies in the eccentricity of the crane load to the side columns and the middle columns of the bent frame in actual use, resulting in differences in the cross-sectional dimensions, foundation sizes and reinforcement areas of the side columns and the middle columns. This difference is more prominent when the tonnage of the crane is larger

Therefore when this crane girder positioning method in the prior art is in use, its use effect is still not ideal enough
