Abstract

The invention provides a mounting method for a door-type steel frame structure of a C-type closed material field. The method comprises the following steps of sectioning, assembling, mounting, hoistingand fixing, and accessory member mounting, wherein in the step of sectioning, sectioning is conducted on any combined steel frame in the door-type steel frame structure in advance; in the step of assembling, assembling is conducted on each section structure on the ground; in the step of mounting, a safety device is mounted on each section structure on the ground in advance; in the step of hoisting and fixing, each section structure with the corresponding safety device mounted is sequentially hoisted to the pres-set mounting position, fixing is conducted on each section according to the presetsequence so as to achieve mounting of each assembled steel frame, and mounting is conducted on the rest of assembled steel frames by repeating the above steps; and in the step of accessory member mounting, after every two adjacent assembled steel frames are mounted, mounting is conducted on an accessory member between the two adjacent assembled steel frames. By means of the method, the transportation of various components and the assembly on the ground are facilitated, the controllability of each safety device during mounting is effectively guaranteed, the mounting time is shortened, the quality and accuracy after mounting are ensured, and the consumption of resources is further reduced.

Description

technical field

[0001] The invention relates to the technical field of steel structure construction, in particular to a method for installing a door-type steel frame structure in a C-shaped closed material yard. Background technique

[0002] With the upgrading of users' production capacity, the amount of raw materials is increasing, and the country's environmental protection requirements are becoming more and more stringent. Raw material yards are one of the main sources of pollution in metallurgical enterprises. In order to reduce environmental pollution and reduce material loss, open-air stockyards are closed. The stock yard is an important measure to reduce environmental pollution for many newly built or renovated environmentally friendly raw material yards at home and abroad.

[0003] Due to the large span and high height of the C-shaped closed factory building in the sky leaking stockyard, the construction of the steel structure of the factory building is extremely diff...
