Embodiment 1

[0043] Specifically, see attached figure 1 As shown, the present invention relates to a kind of composite reinforcement of the side column of the beam-column system of the wooden structure house in ancient buildings, which consists of a wooden column 1, a wooden beam 2, an outer hoop steel ring 3, a single iron piece 4, a transverse fiber cloth 5, and a spiral on the beam. Fiber cloth hoop 6, helical fiber cloth hoop 7 on the column, foundation stone 8, column foot iron piece 9, wooden strip 10, drainage hole 11 and rubber pad 13 are formed.

[0044] First, the horizontal fiber cloth 5 is symmetrically pasted on the lower part of the wooden beam 2 along both sides of the length direction of the wooden beam 2, and the two ends are extended and wrapped around the wooden column 1 and then pasted. Paste on the wooden beam 2, extend and wrap the two ends of the wooden column 1 and paste it, wrap the helical fiber cloth hoop 7 on the column on the wooden column 1 and paste it, and t...

Abstract

The invention discloses a historic building timberwork beam-column system house composite strengthening method. The method comprises the steps that wooden columns are included. After transverse fiber cloth extend and are wound on the wooden columns, spiral fiber cloth on pasting columns are hooped on the transverse fiber cloth, beam columns are connected into a beam-column system through mortises and tenons, mortise-tenon joints of the beam columns are strengthened through the transverse fiber cloth pasted to wooden beams and the wooden columns and single-opening iron parts or double-opening iron parts hooped on the wooden columns, and the transverse fiber cloth is compacted and anchored on the wooden beams through the spiral fiber cloth pasted to the wooden beams and the single-opening iron parts or the double-opening iron parts. The strengthening defects of existing historic timberwork systems are overcome, the connection reliability of the fiber cloth and the wooden beams is ensured, the bearing capacity of the beam-column components and connection joints can be effectively improved, meanwhile, the repair principles of restoration of the old as the old, restoration of the building original forms and reversibility are met, and the method can be widely used for repair and strengthening of historic building timberwork beam-column systems.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for composite reinforcement of an ancient wooden structure beam-column system building. Background technique [0002] In the wooden structure house system of ancient buildings, the beam-column components are usually connected by mortise and tenon. Among them, the mortise and tenon joint is a commonly used connection form of ancient buildings. It is different from the connection joints of steel structures and concrete structures. The structure of mortise and tenon joints determines that its bearing capacity is often lower than that of components. Seismic Design Principles for Strong Nodes and Weak Members. Due to natural disasters such as earthquakes and strong winds, coupled with the material defects of the wood itself, the repeated pulling out and extrusion of the tenon makes the joint connection loose, easy to pull out the tenon, insufficient bearing ...
