Embodiment Construction

[0053] In order to solve the economic rationality of the amount of steel used in the steel roof system, realize the arbitrary arrangement of the lifting points and the unrestricted span design of the steel roof system, the embodiment of the present invention designs and provides a steel roof truss with parallel chords and parallel chords. Steel roof system made of trusses.

[0054] The steel roof system comprises: at least two parallel chord steel roof trusses and parallel chord trusses connecting adjacent two parallel chord steel roof trusses. The parallel chord truss is a steel truss with a parallel chord structure, which is used as the connection structure of the steel roof system, also known as the connection truss. Preferably, at least two parallel chord trusses are arranged between every two adjacent parallel chord steel roof trusses. For example: figure 1 The steel roof system shown in takes two parallel chord steel roof trusses 1 and several parallel chord trusses 2 ...

Abstract

The invention discloses a steel roof system, which comprises at least two parallel chord steel roof trusses and at least two parallel chord trusses connected with the two neighboring parallel chord steel roof trusses; the parallel chord steel roof trusses comprise an upper chord member and a lower chord member which are arranged in parallel, as well as a vertical web member and / or an inclined web member connected with the upper chord member and the lower chord member; the parallel chord trusses comprise an upper chord member and a lower chord member which are arranged in parallel, as well as the inclined web members connected with the upper chord member and the lower chord member, and two inclined stay bars respectively connected with the two ends of the lower chord member, wherein the upper chord member, the lower chord member and the two inclined web members connected with the two ends of the upper chord member and the lower chord member form an inverse trapezium; the at least two parallel chord steel roof trusses are arranged in parallel; the two ends of the upper chord member of the parallel chord trusses are respectively connected with the lower chord members of the two parallel chord steel roof trusses arranged adjacently; and the outer ends of the two inclined stay bars of the parallel chord trusses are respectively connected with the lower chord members of the two parallel chord steel roof trusses arranged adjacently. The steel roof system can realize unlimited span, simplify the structure system and reduce the steel consumption simultaneously when guaranteeing stability.

Description

technical field [0001] The invention relates to a steel roof system in the field of construction engineering, in particular to a steel roof system in which the roof truss adopts parallel chord steel roof trusses and the connecting truss adopts parallel chord trusses. Background technique [0002] At present, various types of steel roof systems that have been disclosed and used in China come from three national standard atlases, namely: [0003] (1) "Light Roof Trapezoidal Steel Roof Truss 05G515" compiled by the Survey and Design Research Institute of Northern Jiaotong University in 2005. This drawing specifies that the distance between the roof trusses is 6m, 7.5m, and 9m. The roof has two purlins and no purlins. 1.5 or 3.0m, span 15, 18, 21, 24, 27, 30, 33, 36m eight types, no skylight and longitudinal skylight. [0004] (2) "Trapezoidal Steel Roof Truss 05G511" compiled by the Survey and Design Research Institute of Northern Jiaotong University in 2005. This drawing spec...
