Detailed Description
In order to make the purpose and technical solution of the embodiments of the present invention clearer, the following description will clearly and completely describe the technical solution of the embodiments of the present invention by combining the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.
As shown in fig. 1: a maintenance and reinforcement device for ancient timber structure tenon-and-mortise joints is characterized in that the timber structure is a vertical timber framework, the vertical timber framework is provided with tenon-and-mortise joints for mutual fixation, and the tenon-and-mortise joints in the vertical timber framework are provided with through holes 1 penetrating through the joints; the through hole 1 is positioned at the center of the tenon-and-mortise joint, the diameter of the hole is slightly larger than the diameter of the sheath of the sleeve, and the proposal is +2 mm. The reinforcing pin formed by splicing is inserted into the mortise and tenon through hole 1. The through holes at the positions of the mortise and tenon joints are pre-punched outside the plane where the vertical timber frame is located.
