Problems solved by technology
At present, the common residential steel structure system with separate lateral force and gravity resistance generally has the following problems: (1) Beam-column connections are mainly welded, and there are problems such as large amount of on-site welding, slow construction speed, and difficulty in guaranteeing construction quality.
(2) The size of the steel columns and beams is relatively large, which leads to the problem of exposed beams and columns in the room. The resulting column edges and beam platforms affect the indoor view and the use of the house.
(3) The steel structure has poor fire protection and anti-corrosion performance, and the cost of anti-corrosion and fire protection is high
(4) The amount of steel used is large and the cost is high, which restricts the promotion of steel structure houses
(5) The degree of industrialization is low, and a large number of components such as floors and stairs are still mainly cast on site

Embodiment Construction
[0038] The present invention will be described more fully below using examples. This invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.
[0039] For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientatio...

The invention discloses a lateral-force-resisting-and-antigravity-separated residence steel structure system and a construction method thereof. The lateral-force-resisting-and-antigravity-separated residence steel structure system comprises a steel-frame structure and a hollow floor. The steel-frame structure is formed by steel columns and steel beams; the hollow floor comprises prefabricated bottom plates, ribbed beams, filling boxes and cast-in-place concrete layers; the steel beams have H-shaped cross sections, and are composed of upper flanges, web plates and lower flanges; the lower flanges are wider than the upper flanges. According to the lateral-force-resisting-and-antigravity-separated residence steel structure system, the structural modes such as double-pipe combination columns, assembling-type connection nodes and the assembling-type hollow floor are adopted, the residence steel structure system has the advantages of being high in assembling degree, good in applicability (column edges and beam tables are free in room), capable of saving the antiseptic cost and the fireproof cost, good in seismic performance, moderate in cost and the like, and broad application prospects are achieved.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a residential steel structure system with separate lateral force resistance and gravity resistance and a construction method thereof. Background technique [0002] With the rapid development of my country's economy and society, the development model of the traditional construction industry with high pollution, high energy consumption and high resource consumption has gradually encountered bottlenecks. Green buildings and construction industrialization have become new trends in the development of the current construction industry. Steel structure buildings are inherently industrialized and are the best carrier for industrialized buildings. It is of great theoretical and practical significance to promote the application of steel structures in residential buildings with a large number of areas and to develop a residential steel structure system with separate lateral...
