Embodiment Construction

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

[0032] like 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 is...

Abstract

The invention belongs to the field of steel structure buildings, and particularly relates to a hoisting frame design application method of a continuous truss column top hinging structure. The method comprises the following steps of: 1, a hoisting frame system arrangement stage; 2, a computational analysis stage; 3, a hoisting system design and manufacturing stage; 4, an installation stage; 5, a hoisting and monitoring stage: installing a hydraulic hoisting device and a temporary reinforcement device, hoisting a continuous truss to a target elevation, and carrying out stress strain monitoring; and 6, an unloading and dismounting stage: hoisting the structure to a target elevation position, then, unloading the hydraulic hoisting device, dismounting a hoisting frame and a conversion cross beam, cutting brackets, and finishing the construction. The hoisting frame design application method has the advantages that the completeness of the original truss structure is ensured; the influence on an existing structure is avoided; the form is simple and compact; the stress is reasonable; the construction is convenient; and the economical performance is good, and the like.

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...
