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

Abstract

The invention discloses a positioning method for a crane beam of a single-layer multi-span bent column. The distance from the center line of the crane beam installed on the corbel of the side column of the bent frame to the span marking line of the side column of the bent frame is L1, so that the center line of the crane beam installed on the corbel of the middle column of the bent frame to the span line of the bent frame The distance between the span markings of the center column is L2, and L1 is greater than L2. The invention adjusts the positioning dimension between the center line of the crane beam on the corbel of the traditional bent frame side column and the center column and the span marking line of the column, so that the effect of a single crane load on the side column and the center column is basically the same. The invention has the advantages of making the single-layer multi-span bent frame column and the foundation evenly stressed, and has the advantages of saving engineering investment and the like.

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...

Problems solved by technology

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
