[0002] Huizhou wooden structures are a system of columns and beams, roofs and external walls. Affected by the environment, materials, external loads and biological pests, wooden columns are prone to decay and deformation, which in turn affects the safety of cultural relics.

[0003] The decay of wooden columns mostly occurs at the roots. In order to ensure the safety of the architectural structure of cultural relics, the staff needs to carry out local repairs on the decayed parts. Common local repair methods include column root inlay and pier joint method, etc. At present, the pier joint structure of wooden columns in the industry mostly adopts the method of half-tenon at the end and iron hoop embracing. The operator inserts the dovetail on the new wooden column into the mortise of the original wooden column, and then fixes the new wooden column and the original wooden column with the iron hoop.

The operator adjusts the position of the new wooden column so that the mortise is aligned with the tenon. The operator pushes the new wooden column to move, thereby making the first overlapping section and the second overlapping section approach each other. When the inner side wall of the first overlapping section coincides with the inner side wall of the second overlapping section, the operator uses the driving assembly to move the positioning column, thereby inserting the positioning column into the positioning groove. The positioning column is conducive to strengthening the connection strength between the first overlapping section and the second overlapping section, thereby strengthening the connection strength between the new wooden column and the original wooden column.

[0050] The implementation principle of the ancient building wooden column pier joint structure of the present application embodiment is as follows: the operator adjusts the position of the new wooden column 3 so that the mortise 32 is aligned with the tenon 22, and the operator pushes the new wooden column 3 to move, thereby inserting the mortise 32 into the tenon 22. When the inner side wall of the first overlapping section 21 coincides with the inner side wall of the second overlapping section 31, the operator pushes the driving rod 41 to move, and the driving rod 41 moves to drive the driving block 42 to contact the abutting block 45, and the driving block 42 causes the abutting block 45 to rise through the inclined surface, and the abutting block 45 rises and drives the positioning column 33 to rise, so that the positioning column 33 is inserted into the positioning groove 26.

[0051] When the driving block 42 is fully inserted into the driving groove 44, the operator pushes the rack 62 to move along the guide groove 36, the second magnet 73 attracts the first magnet 63 to move, and the first magnet 63 assists in driving the rack 62 to move. The movement of the rack 62 drives the rotating gear 61 to rotate, and the rotating gear 61 drives the bidirectional screw rod 52 to rotate. The rotation of the bidirectional screw rod 52 on the one hand causes the connecting column 54 to be inserted into the connecting groove 23, and the rotation of the bidirectional screw rod 52 on the other hand causes the locking column 53 to be inserted into the locking groove 411, thereby causing the positioning column 33 to be inserted into the positioning groove 26. The arrangement of the positioning column 33 and the connecting column 54 is conducive to strengthening the connection strength between the first overlapping section 21 and the second overlapping section 31, thereby strengthening the connection strength between the new wood column 3 and the original wood column 2.
