Description

A multi-story fabricated steel frame-prestressed eccentric support system

technical field

Background technique

According to the statistics of the China Iron and Steel Association, my country's steel output exceeded 700 million tons in 2011, ranking first in the world's steel output for 16 consecutive years. The development of the structure is seriously lagging behind. At present, in developed countries, such as the United States and European countries, the steel structure construction area accounts for more than 50% of the total construction area, and Japan accounts for 80%, while our country accounts for less than 4%. the

Moreover, traditional buildings have disadvantages such as long construction period, serious waste of materials, and heavy pollution during construction, which cannot meet the needs of rapid reconstruction after the earthquake. Therefore, after learning the tragic lessons of the Wenchuan earthquake, it is imperative to innovate the industrialized assembly high-rise steel structure system. Relevant research not only conforms to the national development strategy of promoting the use of steel structures and promoting housing industrialization, but also meets the needs of energy conservation and emission reduction, and has broad development prospects and application value. the

At present, prestressed cables are only used in long-span space structures, and the introduction of prestress into high-rise buildings has not yet been realized as a lateral force-resistant component in actual engineering. In the traditional steel frame structure system, the lateral stiffness of the structure is small, and the displacement between floors is large under the action of wind and earthquake loads, which is difficult to meet the comfort requirements. The new multi-story steel structure frame-prestressed eccentric support system adds transverse and longitudinal prestressed tensile supports on the basis of the steel frame, which improves the lateral stiffness of the structure and improves the deformation performance of the structure. the

6. in according to claim 1 how high-rise assembling type steel structure framework-prestressing force eccentrical braces, it is characterized in that: the assembling column is by box column (5) and flanged plate II(7) or flanged plate III(8) or flanged plate IV(9) be welded, shape difference according to flanged plate can be divided into the flanged plate corner post, flanged plate side column and flanged plate center pillar; With flanged plate III(8) locate up and down welding at box column (5), thus form the flanged plate corner post; With flanged plate II(7) locate up and down welding at box column (5), thus form flange edges of boards post; With flanged plate IV(9) locate up and down welding at box column (5), thus form the flanged plate center pillar; Described three kinds of assembling columns all are prefabricated in the factory, and bolt is adopted in the job site, and the flanged plate of described column is connected with the flanged plate of described Fabricated Beam-Slab center pillar block node, realize the assembling of column and beam slab, thus the formation steel framed structure.

7. in according to claim 1 how high-rise assembling type steel structure framework-prestressing force eccentrical braces, described floor (17) can use composite deck slabs, precast monolithic concrete floor, superimposed sheet composite floor, close rib OSB plate, soft steel board, steel bar girder superimposed sheet, fiber cement board pressure.
