Abstract

The invention relates to a mounting method of a cross-lane construction support. A half-*-shaped support is arranged between a main longitudinal beam and each sub longitudinal beam of a construction support surface, and the overall construction rigidity, the local construction rigidity and the structural stress of the construction support are analyzed based on a space finite element method; based on the long-wave effect after the surface of the construction support is deformed, structural optimization for improving the overall vertical rigidity of the construction support is given; the positions of the sub longitudinal beams are given based on the deformation and stress states of the sub longitudinal beams to the construction support surface; based on the deformation and stress state of the main longitudinal beam, structural optimization for reducing the load effect of the main longitudinal beam is given; and the component rigidity range is given for the steel consumption of the construction support based on the construction local rigidity. After the main longitudinal beam, the sub longitudinal beams, the half-*-shaped supports, cross beams and transverse ribs are additionally arranged on the construction support surface to form a brand new support structure, under the condition that the construction steel amount is basically not increased, the local rigidity and the overall rigidity of the construction support are increased, and the combined action degree of the construction support surface, the main longitudinal beam and the sub longitudinal beams is increased.

Description

technical field [0001] The invention relates to the technical field of cross-lane construction brackets, in particular to an installation method of cross-lane construction brackets. Background technique [0002] When carrying out construction work across multiple lanes, construction methods such as the jacking method and the cross-road loose splicing method are usually used. Among them, construction supports need to be erected when using the cross-road loose splicing method, and the construction and structure of the construction supports have become important aspects that affect the traffic of vehicles and even the safety of construction personnel, construction heavy objects and vehicles below. In order to ensure the normal passage of the lane during the construction period, a wide door opening is adopted, and the left and right lanes under the support are used during the construction period. For roads with more than two lanes, the reduction in the number of lanes may cause...
