Embodiment Construction

[0052] Taking a certain project as an example, the main building has 6 floors above ground and 1 floor underground (partly 2 floors underground); it mainly includes high-rise structures and corridor structures. Among them, the high-rise structure generally adopts a steel frame-support structure system, which is a space truss style; figure 1 As shown, the space truss includes a ring truss 1, a main truss 2 and a truss column 4, the ring truss 1 includes a plane truss and an arc truss, the space truss also includes a suspension frame, a buckling support, etc. Type, H type, round pipe, etc. The main structural materials are Q345GJ, Q345B, etc. The floor is mainly made of steel truss composite floor. The length of the corridor is about 200 meters, and the main components adopt box-shaped and H-shaped sections.

[0053] Such as Figure 1 to Figure 11 As shown, a complex space truss overall hoisting system includes an external ring truss 1, a main truss 2 connected inside the ring...

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...
