Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0044] Such as figure 1 shown.

[0045] A super-large-span double-layer grid dome construction process, which includes the following steps:

[0046] First, determine the architectural dimensions of the dome, including height and diameter, based on the storage capacity and the equipment to be installed;

[0047] Secondly, according to the size of the building, the number of grids of the entire dome is calculated according to the side length of 3-5 meters, and then the number of nodes is calculated;

[0048] Third, input the local meteorological parameters of the dome to be built plus the calculated mesh number and node number of the entire dome into the finite element analysis element (such as SFCAD issued by Beijing Yunguang Design Consulting Firm, Shanghai Tongji University Tonglei Civil Engineering 3D3S Korea Midas Technology Co., Ltd.'s Mudas gen ...

Abstract

The invention provides a super-large span double-layer net rack dome construction process. The process is characterized in that computer wind tunnel simulated software is used to compute wind load of grid to replace wind tunnel test of the whole spherical shell, so that the accurate steel consumption can be worked out; according to the steel consumption in each square meter, the sizes and nodes of members are worked out; in construction, by ring-by-ring construction closing and a small standing derrick sling, small splicing units are lifted, thereby solving the problems of difficult construction and overcoming the defects of difficult construction management and high cost due to full framing construction. The process has the advantages of greatly reducing steel consumption, shortening construction period by more than 50 percent, and substantially lowering construction cost.

Description

technical field [0001] The invention relates to a building construction method, in particular to a method for designing and manufacturing a double-layer grid structure dome with a diameter of more than 100 meters, which can greatly reduce the amount of steel used per square meter. Layer grid dome construction technology. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for coal and other raw materials in coal, electric power, cement, chemical and other industries has increased, and its storage facilities have also been built on a large scale. These storage facilities are mainly various storage bins and dry coal sheds, which play the role of environmental protection and shelter from wind and rain. With the increasing scale of coal mines, power plants and cement plants, the span and length of coal storage sheds are also increasing, and the requirements for its design technology are also getting higher and higher. ...
