Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] As shown in Figure 1-13.

[0046] A construction process for a super-large-span grid arch shed storage silo, which includes the following steps:

[0047] First, according to the local meteorological conditions, according to the most unfavorable meteorological conditions and the physical parameters of the shed, the span is more than 100 meters, the height is 60 meters, and the storage capacity is 80,000 tons. The size of the grid node rods is obtained by using CFD numerical wind tunnel calculation technology and finite element algorithm. , that is, the diameter of the ball head of each node and the geometric parameters of the rods installed on it, draw the construction drawings, which should at least include the number of each node and the number of rods at each node; the specific calculation method can be used The calculation method of t...

Abstract

The invention relates to a construction process of an ultra-large-span net-frame arch-shaped shed type storage silo, which is characterized by comprising: obtaining dimensions of node rods of a net frame via a CFD (computational fluid dynamic) numerical wind tunnel computing technology and a finite element algorithm at first according to local weather conditions, the most adverse weather conditions and physical parameters of an arch-shaped shed, i.e. the ball head diameter of each node and geometric parameters of the rods on each node, and preparing a construction drawing, wherein the construction drawing at least comprises the serial number of each node and the number of rods on each node; and dividing construction steps into installation of basic units and installation of overhead cantilever units. Scaffolds are not needed to be erected in a whole house. The invention has the advantages that the time and materials can be saved, and the process is safe and reliable.

Description

technical field [0001] The invention relates to a manufacturing method of logistics equipment, in particular to a manufacturing method of a steel structure grid storage bin, specifically a super large-span grid arch shed with a span of more than 100 meters and a height of more than 60 meters. Silo construction process. Background technique [0002] At present, with the rapid development of my country's economy and the requirements of environmental protection, the demand for coal and other granular raw materials in coal, electric power, cement, chemical and other industries is increasing, and its storage facilities have also been developed on a large scale. These storage facilities are mainly used to store granular and powdery raw (cooked) materials. They play the role of environmental protection and shelter from wind and rain, not only protecting raw materials from loss but also protecting operating equipment. [0003] With the increasing scale of coal mines, power plants, ...
