Triangular light steel keel roof truss system

Abstract

The invention relates to a triangular light steel keel roof truss system. The triangular light steel keel roof truss system comprises a plurality of main body triangular roof trusses which are locatedon the triangular light steel keel roof truss system and longitudinally and evenly distributed along a house, vertical support trusses located at the two ends of the main body triangular roof trusses, and a plurality of roof truss longitudinal support trusses located between the every two adjacent main body triangular roof trusses, and the main body triangular roof trusses are of a triangular structure formed by two roof surface upper chord trusses and a roof surface lower chord truss; the roof surface upper chord trusses, the roof surface lower chord truss, the vertical support trusses and the roof truss longitudinal support trusses are all provided with a plurality of web members, and the inner parts of the trusses are divided into triangular lattice structures through every two adjacent web members; and the web members in the roof truss upper chord trusses keep vertical direction at intervals of one web member, and the web members on the nodes of the two roof surface upper chord trusses are in the vertical direction. According to the triangular light steel keel roof truss system, the structure is stable, the triangular light steel keel roof truss system is suitable for houses with the span being 8-10 m, and the space in the roof truss can be used.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a triangular light steel keel roof truss system. Background technique [0002] The light steel keel house is a kind of prefabricated house with energy saving, environmental protection, high degree of industrialization, and quick construction. It has wide application and development prospects in various multi-storey and low-rise building constructions. [0003] Affected by the cold-formed thin-walled steel components in the main material of light steel keel house construction, in general light steel keel house construction activities, the span of the main load-bearing beam is not large, basically within 4.8m. In the roof construction, the roof trusses mainly form a triangular sloping roof in the form of vertical rods and horizontal connecting rods. The vertical rods are dense, and the roof trusses are basically completely isolated. The space in the middle of the roof trusse...

AI Technical Summary

Problems solved by technology

In roof construction, the roof trusses mainly form a triangular sloping roof in the form of vertical rods and horizontal connecting rods. The vertical rods are dense, and the roof trusses are basically completely isolated. The space in the middle of the roof trusses is almost unusable. Inconvenient, for a large-span structural system, the conventional roof slope will lead to prominent stability problems of the vertical web members of the roof truss
