Example Embodiment

[0052] Taking a project as an example, the main floor is 6 floors; 1 floor (local underground layer 2); mainly including high-rise structure and inverse structure. Among them, the high-rise structure is generally used steel frame-support structure system, which is a spatial truss pattern; figure 1 As shown, the space truss includes a ring truss 1, a main truss 2, and a truss post 4 comprising a planar truss and a curved truss, and the space truss also includes a hanging frame, buckling support, and the like, the main cross-sectional form Type, H-type, round tube, etc. The inner length is about 200 meters, and the main components use box type and H-type cross section.

[0053] like Figures 1 to 11 As shown, a complex space truss holistic lifting system includes an external ring truss 1, a main truss 2 connected inside the ring truss 1, coupled between the ring truss 1 and the main truss 2, and the laminate 3, The truss post 4 connected at the main truss 2 and the ring truss 1 and t...

Abstract

The invention discloses a construction method of a complex space truss integral hoisting system. The hoisting system comprises an external ring type truss, a main truss connected to the interior of the ring type truss, a coupling beam connected between the ring type truss and the main truss, truss columns connected to the joint of the main truss and the ring type truss, and hoisting frames arranged on the main truss and the ring type truss correspondingly. The overall lifting process of the space truss is simulated through three-dimensional software such as BIM software, and on-site lifting construction can be effectively guided; through pre-arching compensation and monitoring deformation control in the process, the stress uniformity and the mounting precision in the lifting process can be effectively guaranteed; the space truss is partitioned, so that unit splicing is facilitated, the mounting time can be guaranteed, and the mounting precision can also be guaranteed; through overall trial lifting and graded lifting, the installation space of lifting equipment is met, synchronous control during lifting is facilitated, and the in-place installation precision is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method of a complex space truss integral hoisting system. Background technique [0002] With the development of the national economy and the improvement of the technical level of the construction field, large-scale and complex steel structure projects continue to appear. The improvement of the space truss structure should be compared, improved and optimized according to the different characteristics and construction conditions of the project, and the improvement technology and measures should be used to give full play to the construction efficiency and construction quality of the overall improvement technology itself, while shortening the construction period and reducing costs. For space trusses with super large tonnage and complex forms, their installation and lifting are the key points of construction difficulties. How to carry out effec...
