Embodiment Construction

[0031] Next, the present invention will be described in further detail in conjunction with the accompanying drawings.

[0032] Such as Figure 1-7 The shown design and application method of the hoisting frame of a continuous truss column top hinged structure is one of the embodiments of the present invention. The total construction area is 99,200 square meters, with two floors above ground, one floor underground, and interlayers in some places. The main structure is a reinforced concrete frame structure plus a two-way steel truss structure, the supporting structure is a steel reinforced concrete column, and the top of the column is equipped with an anti-seismic spherical hinge support. The steel roof adopts a two-way orthogonal truss structure. The span of the three-span continuous truss is 40m+66m+40m, and the cantilever length on both sides is 25m.

[0033] The steel roof adopts the installation scheme of "partition assembly and partition elevation". The assembly position...

Abstract

The invention belongs to the field of steel structure construction, and specifically relates to a method for designing and applying a hoisting frame of a continuous truss column top hinged structure, comprising the following steps: 1), the stage of hoisting frame system layout; 2), the stage of calculation and analysis; 3), the lifting system Design and manufacture stage; 4), installation stage; 5), lifting and monitoring stage, installing hydraulic lifters and temporary reinforcement devices, lifting the continuous truss to the target elevation, and conducting stress and strain monitoring; 6), unloading and demolition stage, lifting the structure After reaching the target elevation position, the hydraulic lifter is unloaded, the lifting frame, the conversion beam and the corbel are removed, and the construction is completed. The invention has the advantages of ensuring the integrity of the original truss structure, avoiding the influence on the existing structure, simple in form, reasonable in force, convenient in construction and good in economy.

Description

technical field [0001] The invention belongs to the field of steel structure buildings, and in particular relates to a method for designing and applying a lifting frame of a continuous truss column top hinged structure. Background technique [0002] Nowadays, in public buildings, in order to meet the requirements of long-span space, space truss structures with excellent spanning capacity and comprehensive force indicators are favored by engineers. [0003] The large-scale space structure using continuous trusses has repeatedly hit new highs in the number of spans, spans, heights, and weights, which poses greater challenges to installation methods and requires people to constantly seek new construction methods. The hydraulic synchronous lifting technology has the advantages of fast construction speed, high safety performance, no weight limit, suitable for high-altitude and narrow space operations, etc., and is more and more widely used in the steel structure industry. [000...
