[0039] Among them, the repair method for the connection between the lower section 101 of the column and the upper section 102 of the column is specifically the cross-shaped tenon, and it can also be the palm tenon to protect the traditional craftsmanship with these repair methods.
[0040] When the column foot of the traditional-structured wooden column is severely decayed, the local replacement of the wooden column is carried out by using the traditional repair methods of the palm tenon and the cross-shaped tenon. Figure 2It is a repair connection method for the mortise and tenon. When the column foot of the lower part 101 of the column or the upper part 102 of the column is damaged, first select a wooden column of the same material and cross-section. Subsequently, according to the selected connection method of the wooden column, a staggered slot one 201 or a staggered slot two 202 is opened on the lower part 101 of the column or the upper part 102 of the column. After completion, the lower part 101 of the column and the upper part 102 of the column are inserted together through the opened staggered slot one 201 and staggered slot two 202. Subsequently, a circular ring groove 203 with a thickness twice that of the iron hoop 204 is opened at the connection between the lower part 101 of the column and the upper part 102 of the column. Then, the iron hoop 204 is nailed into the circular ring groove 203 through round nails. Then, the steel sleeve 205 is fixed at the connection between the lower part 101 of the column and the upper part 102 of the column through bolts 206, and the repair and connection of the wooden column can be completed.
[0041] Refer to Figure 1 、 3 、4, and 5, the fixing mechanism 3 includes a housing 301 fixedly connected to the outer periphery of the lower part 101 of the column on the upper surface of the original ground 1. The bottom of the first circular ring block 302 is fixedly connected to the upper surface of the original ground 1 inside the housing 301. The bottom of the second circular ring block 303 is fixedly connected to the middle part of the first circular ring block 302 on the upper surface of the original ground 1. The L-shaped grooves 304 are annularly and arrayedly penetrated and opened at the lower middle ends of the first circular ring block 302 and the second circular ring block 303. The outer part of the L-shaped rack 305 is simultaneously slidably connected inside the L-shaped grooves 304 opened in the first circular ring block 302 and the second circular ring block 303. The bottom of the internal gear ring 306 is slidably connected to the surface of the first circular ring block 302. The bottom of the first annular block 307 is fixedly connected to the upper end of the internal gear ring 306. The first annular block 307 rotates between the housing 301 and the second annular block 311. The circular through holes 308 are annularly and arrayedly penetrated and opened on the outer wall of the first annular block 307. One side of the fixing frame 309 is fixedly connected to the inner wall of the first circular ring block 302. The middle part of the gear 310 is rotatably connected to the outside of the fixing frame 309. The upper end side of the gear 310 meshes with the internal gear ring 306. The lower end side of the gear 310 meshes with the L-shaped rack 305. The second annular block 311 is arranged on the side of the L-shaped rack 305 close to the lower part 101 of the column.
[0042] The top of the fixed block 312 is fixedly connected to the bottom of the roof beam 103. A trapezoidal groove 313 is opened on the lower surface of the fixed block 312. The outside of the trapezoidal block 314 is slidably connected to the inside of the trapezoidal groove 313. The middle of the trapezoidal block 314 is threadedly connected to the outside of the bidirectional lead screw 315. The middle of the bidirectional lead screw 315 movably penetrates and is rotatably connected to the inside of the fixed block 312. A threaded groove 316 is opened on one side of the bidirectional lead screw 315. The middle of one side of the threaded post 317 is threadedly connected to the inside of the threaded groove 316. The outside of one side of the threaded post 317 abuts against the surface of one side of the fixed block 312. The middle of the fixing piece 318 is fixedly connected to the outer wall of the other end of the bidirectional lead screw 315. The fixing piece 318 also limits the other end of the bidirectional lead screw 315 at the same time. The upper end of the wedge-shaped block 319 is fixedly connected to the bottom of the trapezoidal block 314.
[0043] When the lower section 101 of the column needs to be repaired, by rotating out the screw inside the circular through-hole 308, then the operator manually rotates the first annular block 307, and the internal gear ring 306 starts to rotate on the top of the first circular ring block 302. Through the rotation of the internal gear ring 306, the gear 310 starts to rotate outside the fixed frame 309. Through the rotation of the gear 310, the L-shaped rack 305 starts to slide inside the L-shaped groove 304. Through the sliding of the L-shaped rack 305, the second annular block 311 can fix or not fix the bottom of the lower section 101 of the column. Then insert the repaired lower section 101 of the column into the middle of the second annular block 311, rotate the first annular block 307 again to fix the second annular block 311 to the lower section 101 of the column, and then fix the repaired lower section 101 of the column by rotating the screw into the inside of the circular through-hole 308.
[0044] When the upper section 102 of the column needs to be repaired, the operator manually rotates the threaded post 317 to make the threaded post 317 no longer fix the bidirectional lead screw 315. Then rotate the bidirectional lead screw 315. Through the rotation of the bidirectional lead screw 315, the two trapezoidal blocks 314 start to slide towards or away from each other inside the trapezoidal groove 313. Through the sliding of the trapezoidal blocks 314, the wedge-shaped block 319 can fix or not fix the upper section 102 of the column. When the repair of the upper section 102 of the column is completed, clamp and fix the upper section 102 of the column again through the wedge-shaped block 319, and finally fix the bidirectional lead screw 315 through the threaded post 317.
[0045] The implementation principle of a reinforcement structure for a wooden column in a traditional wooden structure cultural relic building in an embodiment of the present application is as follows: When the column foot of a traditional structure wooden column is severely decayed, a wooden column of the same material and the same cross-section is selected. According to the selected connection method of the wooden column, a dislocation groove 201 or a dislocation groove 202 is opened in the lower section 101 or the upper section 102 of the column body. Subsequently, the lower section 101 of the column body is inserted together with the upper section 102 of the column body, and the lower section 101 of the column body and the upper section 102 of the column body are fixed by an iron hoop 204. Finally, the connection is protected by bolts 206, and the repair and connection of the wooden column can be completed.
[0046] When it is necessary to fix the lower section 101 and the upper section 102 of the column body after repair or replacement, insert the repaired lower section 101 of the column body into the middle of the second annular block 311, rotate out the screw inside the circular through-hole 308, and then rotate the first annular block 307. The internal gear ring 306 starts to make the L-shaped rack 305 slide inside the L-shaped groove 304 through the gear 310. Through the sliding of the L-shaped rack 305, the second annular block 311 can fix the bottom of the lower section 101 of the column body. Subsequently, rotate the screw into the circular through-hole 308 again to fix the lower section 101 of the column body. Then, by rotating the threaded column 317, the double-headed screw 315 is no longer fixed, and manually rotate the double-headed screw 315. The trapezoidal blocks 314 start to slide towards each other until the wedge-shaped block 319 fixes the upper section 102 of the column body. Rotate the threaded column 317 again to fix the double-headed screw 315. By fixing the double-headed screw 315, the top of the upper section 102 of the column body can be fixed.
[0047] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
