Abstract

The invention relates to a seamless design method and structure for a main workshop of an ultra-long steel structure for a medium and large thermal power plant. The method comprises the steps that a frame is selected in the middle of the main workshop, the main workshop is divided into two parts through the frame, then, connection joints of the frame and all longitudinal members on one part are used as sliding joints, then, a roof board and a wall board on the frame are processed into a stretchable structure, and the whole main workshop can release temperature stress through sliding stretching and retracting formed by the sliding joints during working. The seamless design method and structure have the prominent advantages of being low in building construction cost, reasonable in structure, attractive in overall appearance and the like.

Description

technical field [0001] The invention relates to a super-long factory building structure of a large and medium-sized power plant, in particular to a seamless design method and structure of a super-long steel structure main factory building of a large and medium-sized thermal power plant. It belongs to the technical field of building structures. Background technique [0002] At present, the domestic regulations for the temperature expansion joint spacing requirements of steel structure workshops are as follows: [0003] Article 4.1.5 of "Technical Regulations for Civil Structure Design of Thermal Power Plants" (DL5022-2012) stipulates that the maximum distance between longitudinal temperature expansion joints of steel structure workshops should not be greater than 150m. But it is also mentioned that when there is sufficient basis, the temperature effect calculation and effective measures are taken to meet the design requirements, the temperature expansion joint spacing can be...
