Embodiment 1

[0023] Example 1: The spiral air duct on the truss of the exhibition hall A of a certain exhibition center is a circular air duct, the main specifications are Φ1400mm, Φ1200 mm, Φ1000 mm, Φ900 mm, Φ700 mm, Φ500 mm, and the area of ​​the air duct is about 8400m 2 . Considering that the diameter of the spiral air duct is relatively large, and the truss height of exhibition hall A is 43m, and the net height is about 27m, from the perspective of construction safety and rationality, the air duct on the truss is assembled on the ground, hoisted synchronously with the truss, and finally uses hanging baskets, elevators and other equipment Partial installation is carried out, including the following steps:

[0024] (1) Module division of pipe trusses and spiral air ducts: According to the design documents and drawings, the installation simulation of pipe trusses and spiral air ducts is carried out through BIM technology, the relative installation position of the spiral air ducts is con...

Abstract

The invention discloses a large stadium pipe truss and spiral duct modularization installation method and a combination structure. The installation method includes the steps of module division of pipe trusses and spiral ducts; factory manufacturing of pipe truss module units and spiral duct module units; assembling of pipe truss modules and spiral duct modules on a construction site. The combination structure is formed by arranging the spiral duct module units into the pipe truss module units through a plurality of fixing units in a penetrating mode. According to the large stadium pipe truss and spiral duct modularization installation method and the combination structure, truss structures and the spiral ducts are modularly assembled on the ground according to design models, the trusses and the ducts are hoisted at the same time, so a mechanical and electrical installation construction procedure and a steel structure construction procedure are combined into one, working time is greatly shortened, work high above the ground and setting up of auxiliary facilities are greatly reduced, the technical level and the efficiency are improved, meanwhile installation time is shortened, and safety of constructors is guaranteed.

Description

technical field [0001] The invention relates to a modular installation method and a combined structure of a pipe truss and a spiral air duct for a large venue, and belongs to the technical field of building electromechanical installation modularization. Background technique [0002] As a symbol of the spiritual culture of a country or city, large-scale venue buildings often strive to show the connotation of regional culture and art. It is a multi-functional and comprehensive architectural complex with various styles and changes. The ingenuity of architects often makes the structural design unique, especially the installation of pipe trusses and spiral air ducts in large stadium buildings, which greatly increases the difficulty of building mechanical and electrical installation and construction. Due to the high height, large span, and complex structure of the steel structure, it has caused great difficulties for the electromechanical system installed in the truss, and the con...
