Embodiment Construction

[0024] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0025] The schematic diagram of the positional relationship between metal corrugated arch plates, arch trusses and longitudinal trusses is shown in Fig. figure 1 with figure 2 . The arched corrugated board adopts the MIC-240 board commonly used in the market at present. The roof span is 36m, the rise-span ratio is 0.25, and the board thickness is 1mm. The distance between the arch trusses is 6.1m. mm round tube, the height of the space arch truss is 0.8m, the upper chord node spacing of the fabricated truss is 0.81m, the lower chord node spacing is 0.5m, the upper chord width of the truss is 500mm, and the lower chord width is 300mm. The height of the longitudinal truss is 0.622m, and the planar truss is adopted. The lower chord nodes at both ends of the arch truss are hinged and fixed to the supports of the ori...

Abstract

The invention relates to a method for using assembly steel truss to strengthen the metallic arc ripple roof cover, wherein it is characterized in that: it uses assembly steel truss to be arranged at the inner side of arc ripple plate while their distance is 6-9m; and adds 2-3 longitudinal trusses between each arc truss, to make steel truss and ripple plate share external load, to strengthen the roof cover. And the invention can avoid increasing steel consumption most, to improve the safety and the application of roof cover.

Description

technical field [0001] The invention discloses a method for reinforcing a metal arched corrugated board roof by adopting an assembled steel arch truss, belonging to the technical field of civil engineering large-span steel structures. Background technique [0002] At present, the space structure is developing rapidly in the world. Among many space structures, the metal arch corrugated roof structure has the advantages of less material, light weight, short construction period, large spanning capacity, and the combination of force bearing and maintenance functions. The advantages are deeply concerned and recognized by people in the construction industry. In recent years, my country's engineering practice has shown that it has significant technical, economic and social benefits, has broad development prospects, and will become one of the important development directions of light steel structures. [0003] However, due to the need for arching, there are many small transverse co...
