Embodiment 1

[0066] E.g: figure 1 In the steel roof system shown, the steel roof truss is parallel chord steel roof truss 1, and the connecting truss is parallel chord truss 2. Preferably, at least two parallel chord trusses 2 are arranged between every two adjacent parallel chord steel roof trusses 1 . in, figure 1 The steel roof system shown in takes two parallel chord steel roof trusses 1 and several parallel chord trusses 2 connecting the two parallel chord steel roof trusses 1 as an example.

[0067] figure 1 The two parallel-chord steel roof trusses 1 are arranged in parallel, the two ends of the upper chords 21 of the parallel-chord trusses 2 are respectively connected with the upper chords 11 of the two adjacent parallel-chord steel roof trusses 1, and the two lower chords 22 of the parallel-chord trusses 2 The two ends of each are respectively connected to the lower chords 12 of two parallel chord steel roof trusses 1 arranged adjacently.

[0068] Several typical arrangements ...

Embodiment 2

[0116] E.g: Figure 17 In the steel roof system shown, the steel roof truss is parallel chord steel roof truss 1, and the connecting truss is parallel chord truss 2. Preferably, at least two parallel chord trusses 2 are arranged between every two adjacent parallel chord steel roof trusses 1 . in, Figure 17 The steel roof system shown in takes two parallel chord steel roof trusses 1 and several parallel chord trusses 2 connecting the two parallel chord steel roof trusses 1 as an example.

[0117] The parallel chord steel roof truss 1 includes upper chords 11 and lower chords 12 arranged in parallel, and support rods (including vertical webs 23 and / or diagonal webs 24 ) connecting the upper and lower chords ( 11 , 12 ). The parallel chord truss 2 comprises an upper chord 21 and a lower chord 22 arranged in parallel, a support rod (comprising a vertical web 23 and / or a diagonal 24) connecting the upper and lower chords (21, 22), and one end and the lower chord 22 are connecte...

Abstract

The invention discloses a steel roof system, comprising at least two steel roof trusses distributed parallelly and a plurality of linkage girders used for connecting two adjacent steel roof trusses; wherein, the steel roof trusses are parallel chord steel trusses (1), and the linkage girders are parallel chord girders. The steel roof system provided by the invention adopts steel roof trusses and linkage girders which are in parallel chord structure, thus realizing unlimited span of the steel roof while ensuring the stability thereof, simplifying the structure system and reducing the usage amount of steel.

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...
