Abstract

The invention discloses a roof steel structure. The roof steel structure comprises a concrete frame (1) encircled to form the roof contour, a plurality of main beams and a plurality of secondary beams, wherein the main beams and the secondary beams are arranged in the concrete frame (1). Each main beam is a beam string formed by a rigid beam (2), a lower chord rope (3) and a supporting rod (4). Each secondary beam is formed by a plurality of rigid secondary beam units (5). The two ends of the rigid secondary beam units located between two main beams are welded to the main beams on the two sides respectively. A roof steel structure construction process is further disclosed. The roof steel structure has the advantages that the matching application of the beam strings and the rigid beams is achieved, the beam strings and the rigid beams have complementary advantages, the roof steel structure has both the advantage of bearing vertical pressure through the beam strings and the advantage of bearing vertical and horizontal pressure and reverse pressure through the rigid secondary beams, so that the roof steel structure is good in stability; and compared with a rigid beam roof structure, the roof steel structure is light in self weight and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a roof steel structure and a construction method thereof. Background technique [0002] The string beam structure is a hybrid structural system formed by rigid upper strings, flexible cables, and struts in the middle. Its structural composition is a self-balancing system and a large-span prestressed spatial structural system. As an efficient structural load-bearing system, the pre-tensioned string beam structure has been adopted by various construction projects, especially the roof system of large-span space structures. It makes full use of the tensile properties of high-strength cables to improve the overall structure of the structure. Stress performance. But the string beam also has the technical problem of being unable to bear the reverse load. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roof stee...
