Herringbone roof truss member and roof truss constructed by same

Abstract

The invention provides a herringbone roof truss member and a roof truss constructed by the herringbone roof truss member, relates to the technical field of construction engineering, and solves the technical problems of the existing roof truss that the height is great and an indoor pure space is small. The member comprises two upper chord members, two lower chord members and a landing supporting piece; the top ends of the two upper chord members are connected to form a herringbone beam with an upward pinnacle; the two lower chord members are crossly connected to form an X-shaped supporting beam; the two tops of the X-shaped supporting beam are respectively connected with upper part member bodies of the two upper chord members; the two bottom ends of the X-shaped supporting beam are respectively with the bottom ends of the two upper chord members; the pinnacle part of the herringbone beam is connected with a crossed point part of the X-shaped supporting beam through a vertical middle web member; two sides of the middle web member are respectively provided with a plurality of side web members; one end of each side web member is connected with the upper chord members and the other end of each side web member is connected with the lower chord members; and the two ends of the herringbone beam are respectively mounted on the supporting piece. According to the member and the roof truss disclosed by the invention, large span can be realized, the self height is small and the indoor pure space is large.

Description

technical field [0001] The invention relates to construction engineering technology, in particular to the technology of a herringbone roof truss component and the roof truss constructed therefrom. Background technique [0002] Herringbone roof truss components have a large span, and can build a large-span roof truss, which can meet the large space requirements of many public buildings and industrial buildings. [0003] The existing herringbone roof truss components are mainly composed of two upper string girders built in a herringbone shape and a lower string beam arranged horizontally. The two ends of the lower string beam are respectively connected with the lower ends of the two upper string beams. The lower chord bears the tension. The height of existing gable roof truss components is very large. In order to ensure sufficient indoor clearance, the total height of the overall structure and the height of vertical components must be greatly increased, which not only causes ...

AI Technical Summary

Problems solved by technology

The height of existing gable roof truss components is very large. In order to ensure sufficient indoor clearance, the total height of the overall structure and the height of vertical components must be greatly increased, which not only causes material waste and high cost, but also wastes space and leads to energy increase in consumption

[0004] In addition, a large number of existing industrial buildings need to be transformed into civil buildings such as offices, businesses, or apartments as the times change. Seriously affect the effective use of indoor space, the overall upgrade or change to other forms of roof structure will often change the shape of the building, which conflicts with the planning indicators
