Reinforced old large-span steel-wood roof truss system and construction method thereof

Abstract

The invention discloses a reinforced old large-span steel-wood roof truss system and a construction method thereof. The reinforced old large-span steel-wood roof truss system comprises roof truss units, purlines, roof panels, longitudinal supports and diagonal bracings. Two ends of the roof truss unit are supported on the left main body component and the right main body component; each roof truss unit comprises a roof truss support, a lower chord, a web member and an upper chord; the roof truss support is connected with the left main body component through a first bottom connecting piece and comprises a vertical support, an inclined support and a first steel sleeve; the top of the vertical support is connected with a first steel sleeve head; the top of the inclined support is connected with a second steel sleeve head; the upper chord is of a wood structure and is obliquely arranged between the roof truss support and the right main body component; the upper chord comprises an old upper chord member, a new upper chord member, a first carbon fiber cloth hoop and a first carbon fiber plate; the lower chord is horizontally arranged below the upper chord; the lower chord is made of steel bars, and hanging bars are connected between the lower chord and the upper chord; the web members are arranged between the two lower chords and the upper chord at intervals. The technical problems that an original building style and appearance cannot be preserved and an ancient building cannot be effectively protected when a traditional existing house wooden roof frame is repaired are solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a reinforced old large-span steel-wood roof truss system and a construction method thereof. Background technique [0002] The traditional renovation of old long-span wooden truss houses basically involves dismantling and discarding the original components; This kind of practice will destroy the original style of the building, and the original state of the building cannot be preserved, so that the built house lacks the sense of age of historical accumulation; especially for some buildings with historical research value or buildings with preserved cultural heritage, Such methods cannot provide effective protection. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a reinforced old large-span steel-wood roof truss system and its construction method, to solve the problem that the traditional wooden roof truss repair of existing h...
