Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1-4 Shown, a kind of reinforcement device for loosening the tenon and mortise joints of the wooden structure of ancient buildings, comprises the gap 3 between the tenon and mortise, the gap 3 is located between the tenon and the upper and lower planes of the mortise, and the gap 3 passes through two pieces of wedge-shaped wood. The block 4 is filled, the column 1 outside the gap 3 is wrapped by the carbon fiber cloth 6, the upper side of the column 1 is connected to the component two 11 through the column connector 7, and the beam connector 8 connects the beam 2 and the component one 9 together. 2. Set perpendicular to column 1, the rod-shaped part of member one 9 is inserted into the opening of member two 11, and the shape memory alloy wire 12 bypasses the upper and lower rod-shaped parts of member one 9 and is anchored to the upper and l...

Abstract

The reinforcing device comprises a gap located between mortises and tenons, the gap is located between a tenon and the upper plane and the lower plane of a mortise opening, the gap is filled with two wedge-shaped wood blocks, and the portion, on the outer side of the gap, of a column body is wrapped with carbon fiber cloth. The upper side of the column is connected with the second component through the column connecting piece, the beam and the first component are connected together through the beam connecting piece, the beam and the column are perpendicularly arranged, the rod-shaped portion of the first component is inserted into the hole opening portion of the second component, and the shape memory alloy wire bypasses the upper rod-shaped portion and the lower rod-shaped portion of the first component and is anchored to the upper plane and the lower plane of one end of the second component. Anchoring is achieved through fastening of screws. According to the method, the anti-seismic performance of the damaged node can be effectively enhanced, and the reinforced node has the self-resetting capability.

Description

technical field [0001] The invention relates to the technical field of earthquake resistance of civil engineering, in particular to a reinforcement device and method for loosening tenon and tenon joints of wooden structures of ancient buildings. Background technique [0002] During the service process of hundreds or even thousands of ancient buildings, wooden structures will be subjected to loads such as self-weight and earthquakes. In addition to the influence of changes in the environment and moisture content, the tenon area of ​​the joints often produces extrusion plastic deformation and dry shrinkage deformation. As a result, gaps appear in the joints, resulting in loose and damaged joints, and the seismic performance of the joints, such as stiffness, strength, and energy dissipation capacity, no longer meets the seismic requirements. [0003] The damage of the wooden structure joints of ancient buildings will reduce the overall stability and safety of the structure. The...
