Fabricated support and intelligent hydraulic jacking type mounting method thereof

Abstract

The invention provides an assembly type support and an intelligent hydraulic jacking type installation method thereof.The assembly type support comprises four support foundation stand columns, a cap beam and a plurality of support segments, each segment comprises two support pieces, each support piece comprises two vertical rods, an upper parallel connection and a lower parallel connection are welded between the two vertical rods, and the support segments are connected up and down through flanges; the bracket sheets of the two vertically connected sections are arranged in a staggered manner along the longitudinal and transverse directions of the bracket; the lower ends of the four vertical rods of the lowermost support section are connected with the upper ends of the four stand columns through flanges respectively, and the upper ends of the four vertical rods of the uppermost support section are connected with the cap beam through flanges. When the support is installed, the flat car is used for automatically conveying, rotating and jacking the support pieces, the oil cylinder is used for alternately jacking the installed segments, all operations are conducted on the ground, safety is high, the construction speed is high, the number of needed constructors is small, and the support installation quality is reliable.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, relates to a temporary support erected in bridge construction, and in particular relates to a prefabricated support and an intelligent hydraulic jacking installation method thereof. Background technique [0002] The cast-in-place beam construction supports of bridges usually include steel pipe fastener supports, bowl buckle supports, disk buckle supports, steel pipe Bailey supports, steel pipe profile steel supports, etc. The first three are full-house supports, and the latter two are less-support systems. [0003] There are mainly the following problems when erecting the existing brackets: [0004] (1) The amount of work at heights is large and the safety risk is high; [0005] (2) More manpower and equipment need to be invested, and the construction cost is relatively high; [0006] (3) Due to the structural reasons of the bracket, problems such as loose connection and omission ar...

AI Technical Summary

Problems solved by technology

[0004] (1) There is a large amount of high-altitude operations and high safety risks;

[0005] (2) More manpower and equipment need to be invested, and the construction cost is higher;

[0006] (3) Due to the structure of the bracket, problems such as loose connection and omission are prone to occur, causing potential safety hazards;

[0007] (4) There are also problems such as large deformation loss of the bracket rods, easy damage and loss of fasteners in the full hall bracket, and the steel pipe bracket needs to cut and weld the material when adjusting the bracket elevation, resulting in a lot of material waste
