Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like figure 1 -6 shown.

[0031] A reverse installation construction process of a small-span bolted ball net frame shell storage bin. The span of the shell storage is not more than 80 meters, and the height is not more than 35 meters. The specific construction process includes the following steps:

[0032] First, according to the local meteorological conditions, according to the most unfavorable meteorological conditions and the physical parameters of the shed, the CFD numerical wind tunnel calculation technology and the finite element algorithm are used to obtain the size of the grid node rods, that is, the diameter of the ball head of each node and the diameter of the ball head installed on it. For the geometric parameters of the bars, draw the construction drawings, which should at least include the number of each node and the number ...

Abstract

The invention discloses an installation construction process of a bolt net rack cylindrical shell storage bin, which is characterized by comprising the steps of: firstly, according to local meteorological conditions, obtaining sizes of net rack node rod members by adopting a CFD (Computational Fluid Dynamics) numerical value wind tunnel calculation technology and a finite element algorithm according to most disadvantageous conditions and tunnel physical parameters, namely, drawing a construction drawing by using a bulb diameter of each node and a geometric parameter of the rod members arranged on each node, wherein the construction drawing at least comprises a number of each node and the quantity of rod members of each node; and then dividing the construction step into a starting unit installation and an air overhanging unit installation. Due to no need of erecting an accomplished scaffold, the installation construction process has the characteristics of time and material saving, safety and reliability.

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 reverse installation construction process for a bolted ball grid shell storage bin with a span of less than 80 meters. Background technique [0002] The floor-type shell storage silo is a structural building specially built for storing granular and powdery raw materials (clinker) and protecting operating equipment. It is widely used in coal mines, power plants, cement, steel, chemical and other industries. As the country's requirements for environmental protection are getting higher and higher, the number and scale of storage bins with this structure are increasing, and they are being promoted and applied at an annual growth rate of 20-30%. [0003] At present, the storage bins used in the society are generally divided into two structural forms: one is a circular (spherical) dome storage ...
