Novel wood structure column base joint reinforcement structure and construction method thereof

Abstract

The invention discloses a novel wood structure column base joint reinforcement structure and a construction method thereof. The reinforcement structure comprises a steel bottom plate, multiple reinforcement pieces and at least one hoop assembly. Each hoop assembly comprises an inner hoop, an elastic piece and an outer hoop. The inner hoops are arranged outside a column base in a sleeving manner. The inner diameter of the inner hoops is matched with the section diameter of the column base. The outer hoops are arranged outside the inner hoops. The elastic pieces are clamped between the outer hoops and the inner hoops. A column base hole is formed in the steel bottom plate. The steel bottom plate is fixed to foundation stone where the column base is placed. The column base is located in the column base hole. The diameter of the column base hole is larger than the diameter of the column base. The reinforcement pieces are fixed to the steel bottom plate and are connected with the outer sidewalls of the outer hoops. According to the novel wood structure column base joint reinforcement structure, by arranging the elastic pieces between the inner hoops and the outer hoops, when the columnbase slides, the inner hoops and the column base slide together in a limited manner; and shock absorption energy consumption is achieved through elastic deformation of the elastic pieces, and the improvement of the overall safety of wood structures is facilitated.

Description

technical field [0001] The invention relates to the technical field of wood structure engineering, in particular to a novel wood structure column base node reinforcement structure and a construction method thereof. Background technique [0002] my country's traditional wooden structure buildings have a major structural feature, that is, the wooden column feet are placed directly on the foundation stone at the bottom. In recent decades, scholars at home and abroad have carried out a lot of research on this structural feature, and have greatly appreciated it as a modern sliding vibration isolation bearing. It is true that when an earthquake occurs, a certain lateral movement of the column foot can slow down the large internal force of the frame, but many people have found that the displacement of the column foot is also a form of failure, and some suggestions for strengthening the column foot joints have also been proposed. The innovative design idea and applied for a patent,...

Problems solved by technology

[0003] The utility model patent with the notification number CN207597720U discloses an anti-seismic node structure of a wooden column foot, by pre-embedding the ring-shaped flange steel plate and the vertical arc-shaped steel sheet in the foundation of the wooden column foot, the steel sheet and the round wooden column Fixing with bolts controls the displacement of the column foot. This method completely limits the slippage of the column foot, but it cannot consume the internal force of the round wooden column, and it will still cause damage to the round wooden column, and the steel sheet and the round wooden column pass through. The bolts are fixed, and the bolts pass through the round wooden pillars, and the round wooden pillars must be drilled to artificially damage the structure of the round wooden pillars
