Embodiment 1

[0040] Such as Figure 1-Figure 2 As shown, a large-span triangular truss aerial swivel lifting construction method specifically includes the following steps:

[0041] S1: Construction preparation: model according to the construction drawing, and split and number the steel beams, truss tubes and related components in the model, and process the finished components according to the model;

[0042] S2: Surveying and setting out: establish a site surface control network, which includes the starting point and starting edge as the basis for site positioning, the main point and main axis of the building, and related control lines and control points, so as to form a surrounding parallel to the building the closed figure of

[0043] S3: tire frame assembly: build the roof truss assembly tire frame 1, and set them on the embedded parts of the concrete structure of the elevated floor and on the ground respectively;

[0044] S4: Lifting frame assembly and roof truss lifting: Build the l...

Embodiment 2

[0069] Process flow is as follows in the present embodiment:

[0070] Construction preparation→measurement and setting out, marking and positioning→tire frame assembly→lifting frame assembly→roof truss assembly→

[0071] Pre-lifting of the roof → formal lifting of the roof (air swivel) → unloading of the lifting frame;

[0072] Specific steps are as follows:

[0073] 1. Construction preparation

[0074] According to the design drawings, BIM software is used to model the steel structure of the station building. According to the model, steel beams, truss tubes and other components are accurately split and numbered. The materials are cut according to the project construction schedule, and the factory is customized according to the specified specifications and models, and then enters the site to prepare for inspection and installation. After the components enter the site, check the external dimensions, welding quality and coating quality of the components according to the requ...

Abstract

The invention relates to the field of steel structure truss roof construction, and discloses a large-span triangular truss air rotation lifting construction method which comprises the specific steps that construction preparation is conducted; measuring, setting out, marking and positioning; assembling a jig frame; splicing the lifting frame; assembling a roof truss; lifting the roof (turning in the air); mounting an inlaying area; and unloading the lifting frame. The problem that the truss hoisting space and the truss lifting space are not enough can be solved, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of steel structure truss roof construction, in particular to a construction method for lifting a large-span triangular truss in mid-air. Background technique [0002] In recent years, steel structure truss roofs have been widely used in large public building roofs. The shape of the truss structure is simple and beautiful, the primary and secondary structures are distinct, and a large span can be realized. The main components are all cut, cut, and pre-installed in the factory through the software model, with high installation accuracy and less on-site welding. Due to the vigorous development of modern architectural art, all kinds of large public buildings, especially landmark buildings, have elegant and unique shapes, and the roof shapes are even more ingenious. And the space required for hoisting is not enough. This kind of roof facade is beautiful in form, but it adds a lot of difficulty to the construction. Cont...
