Problems solved by technology

[0013] The purpose of the present invention is to solve the existing long-span cylindrical shell grid structure with long installation and construction period, high cost, many auxiliary installation equipment required and unfavorable construction safety In order to solve the problem of many factors, we invented a kind of "self-structure" of the shell gable grid, that is, the gable grid structure-the "stable starting unit" of the gable wall is the construction support structure and bears the construction load, and the "ultra-large-span tube" is installed in one direction. The construction method of "shell grid structure", that is, the gable grid structure is used to bear the construction load. From the gable grid structure, the "high-altitude bulk method" is adopted along the longitudinal direction of the cylindrical shell grid structure to complete the installation of the subsequent cylindrical shell grid structure.

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Such as Figure 1-8 shown.

[0044] A construction method for a super-large-span cylindrical shell grid structure, the key technology of which is to first install the gable grid structure at one end of the cylindrical shell structure, and use the gable grid structure as a stable "starting unit" for the installation of the entire cylindrical shell structure, and then use the existing The installed "stable starting unit", that is, the gable grid structure, bears the construction load. From the gable along the longitudinal direction of the shell structure, the "high-altitude bulk method" is used to complete the installation of the subsequent shell grid structure.

[0045] Specific steps are as follows:

[0046] (1) Construction preparation

[0047] 1. On-site basic handover and acceptance

[0048] 1.1 Measure and accept the completed concrete fo...

Abstract

The invention relates to a super-long-span cylindrical shell lattice structure construction method, which is characterized in that a gable wall lattice structure at one end of a cylindrical shell structure is installed firstly, and then the gable wall lattice structure is used as a stable starting unit for installing the entire cylindrical shell lattice structure, i.e. the installed gable wall lattice structure which is used as the stable starting unit is used for bearing construction load and the subsequent installation of the cylindrical shell lattice structure is finished by starting from a gable wall along the longitudinal direction of the cylindrical shell structure by adopting a high-altitude bulk method. The super-long-span cylindrical shell lattice structure construction method has the characteristics of high construction efficiency, high safety, low construction cost, high construction quality and the like, and has the advantages of high efficiency, high safety, low construction cost and high construction quality which are better reflected especially during installation of long-span and super-long-span cylindrical shell lattice structures.

Description

technical field [0001] The invention relates to a construction method of a steel structure building, in particular to a construction method of a large-span steel structure building with a span of 60 meters or more, in particular to a construction method of a super-long-span cylindrical shell grid structure. Background technique [0002] At present, the existing construction and installation methods of super-large-span and medium- and small-span cylindrical shell grid structures mainly include: [0003] 1. Construction process of full hall or partial scaffolding: set up full hall or partial scaffolding to form an installation platform, and then use the "bulk method" on the scaffolding platform to complete the installation of the entire shell structure. [0004] 2. "The installation process of using the tower support to form a "tube shell starting unit" by closing and arching the pieces: the installation method of the starting unit of the cylindrical shell grid structure is to...
