A method for expanding and installing the closed shed of cylindrical reticulated shell

Abstract

The invention discloses a cylindrical latticed shell sealed canopy and an expanded installation method thereof. Bidirectional elastic plate type rubber supports are adopted and rotary centers of the two supports are overlapped with spherical centers of support bolts; the labor division is definite, the transmission is reasonable and boundary assumptions are consistent. In an installation process, a spherical hinge support composed of a lateral temporary limiting support and a vertical support can be adaptive to the outer surface of a spherical bolt very well, can rotate around the spherical bolt and can limit the movement of the spherical center of the spherical bolt. The structure of the lateral temporary limiting support and time nodes for mounting and dismounting the lateral temporary limiting support are defined, so that project safety accidents caused by the fact that the supports are unstable or support balls slide out in the project are avoided. A steel wire rope and a wind cable rope are used so that the supporting stability is improved and the reliable connection is realized. In an installation process disclosed by the invention, a scaffold does not need to be established and lifting equipment including a crane and the like is used as auxiliary tools, so that safe, efficient and economic construction is realized and the construction period is short. The installation precision is high and the selection of a closing position is economical.

Description

technical field [0001] The invention relates to an installation method of a cylindrical reticulated shell coal yard structure, in particular to a method for expanding and installing a parent structure of a large-span cylindrical reticulated shell closed shed based on a rotatable hinge support. Background technique [0002] In order to improve the utilization rate of coal and reduce environmental pollution, coal storage sheds or dry coal sheds need to be set up in coal transportation stations, transfer stations, and power stations to form a closed enclosure for coal storage sites. This type of closed shed with large span and high height The scientific, economical and reasonable solution is to adopt the cylindrical reticulated shell structure, which has been verified. However, its installation process has been constantly changing and discussing. Cost and duration depend on the installation process. [0003] Commonly used construction methods for cylindrical reticulated shell...

AI Technical Summary

Problems solved by technology

These construction methods have their own characteristics, but there are the following problems to varying degrees: a large amount of temporary support scaffolding, a long construction period; Splicing is difficult; the potential safety hazard of the temporary load-bearing support is prominent; the stability of the jacking device is prominent; more equipment is required, etc.

For extra-large and super-high cylindrical reticulated shells, the construction cost and construction difficulty are still relatively large
