Ultra-wide steel plate wind pipe and its reinforcement and hoisting construction method

Abstract

The invention discloses a fixing and hoisting method of a super-wide steel plate type air pipe. The fixing and hoisting method is characterized in that a supporting pipe used for supporting the height direction of the air pipe, and the supporting pipe is hollow; a hanger rod used for hoisting the air pipe is penetrated through the supporting pipe, one end of the hanger rod is penetrated through the top surface of the air pipe and then penetrated through the floor slab to be fixed on the hoisting rod, and the other end of the hoisting rod is penetrated through the base surface of the air pipe and is fixed with the air pipe together. At the position with large space and large air output, by adopting the air pipe with the super-wide section in the invention, the construction procedure can be simplified, the utilization coefficient of the space is enlarged, and the good utilization effect is obtained. A hoisting and reinforcing integrated method that the steel pipe is taken as the sleeve of the supporting rod, and the hanger rod is penetrated through the sleeve of the supporting rod, thus the problems of supporting and hoisting of the super-wide steel plate type air pipe are solved.

Description

technical field [0001] The invention relates to an ultra-wide steel plate air duct, in particular to a method for solving problems such as reinforcement and hoisting of the ultra-wide air duct. Background technique [0002] In recent years, in airports, exhibition centers, gymnasiums, hydropower plants and other occasions that need to transport a large amount of air, the application of large cross-section air ducts is increasing day by day, and the maximum aspect ratio of rectangular air ducts is also relaxed to 10:1. However, there is no corresponding reference basis in the design and construction process, and the design and selection of related parameters are mainly based on experience and simple theoretical calculations. In many cases, the selected safety factor is too large, resulting in waste of materials and energy consumption. Therefore, it is necessary to carry out comprehensive technical research and systematically analyze the special problems that appear in the ult...

Problems solved by technology

[0003] The air duct section size of Qingdao Liuting Airport Terminal Expansion Project is 7000mm×1000mm. Due to the large section of the air duct, its self-weight, size and aspect ratio have exceeded the scope of the current code, so it is very difficult to construct according to the conventional method. And can not guarantee the construction quality and use effect
