[0023] Step E: if the cross beam and the top column are difficult to disassemble, insert the oil outlet mechanism into the secondary support frame on the upper end of the connection main frame, wherein the fixed column pushes the movable column upward, the movable column pushes the S-shaped shielding plate upward, one end of the S-shaped shielding plate moves from the first cavity to the inside of the temporary storage cavity, and then the S-shaped shielding plate separates the space inside the temporary storage cavity, so that the lubricating oil in the oil tank does not flow into the temporary storage cavity, and the lubricating oil in the temporary storage cavity flows into the oil outlet pipe through the through hole, the oil outlet pipe is aligned with the gap between the cross beam and the top column, the lubricating oil flows into the gap between the cross beam and the top column and lubricates the gap, and the repair and disassembly of the cross beam and the top column are facilitated.

[0024] Compared with the prior art, the method has the following beneficial effects:

[0025] 1. In this invention, a first insert post located at the front of the lower end of the top block is inserted into a first slot, a second insert post is inserted into a rear slot and a front slot, and a first insert post located at the rear of the lower end of the top block is inserted into a second slot. The second insert post is snapped onto the lower side of the first and second fixing frames. Through the splicing of the snap-fit ​​structure, the fixing performance between the connecting structure and the fixing structure is further improved. The splicing connection between the connecting structure and the fixing structure positions the connecting structure at the front end between the two supporting structures, thereby enabling multiple connecting structures to splice and connect the two supporting structures. By replacing existing bolts and other connectors with the connecting structure, snap-fit ​​structure, and fixing structure, the assembly of the supporting structure is quick and convenient.

[0026] The connecting and fixing structures connect the two support structures into a whole, strengthening the support of the support structures for the beams.

The modularity of the support and connecting structures makes the assembly more flexible, and the support columns improve the support performance of the support structures for the beams, thus improving the stability of the support.

[0027] 2. During the upward movement of the S-shaped baffle, the through hole allows the lubricating oil inside the S-shaped baffle to gradually flow to the outside through the oil outlet pipe, avoiding the phenomenon of lubricating oil being squeezed back when the S-shaped baffle moves upward. The oil outlet pipe is aligned with the gap between the crossbeam and the top column, so that the lubricating oil lubricates the crossbeam and the top column, which facilitates the repair and disassembly of the crossbeam and the top column.

[0043] Figures 8 to 10As shown, the uppermost end of the connection main frame 401 is clamped with a secondary support frame 14, one side of the upper end of the secondary support frame 14 is fixedly connected with a fixed column 13, and the upper end of the secondary support frame 14 is inserted with an oil outlet mechanism 12. The oil outlet mechanism 12 comprises an oil storage tank 1201 inserted at the upper end of the fixed column 13. One side of the oil storage tank 1201 is provided with a temporary storage cavity 1202. One side of the temporary storage cavity 1202 is provided with an oil outlet pipe 1210. One side of the lower end of the temporary storage cavity 1202 is provided with a first cavity 1203. The inside of the first cavity 1203 and the inside of the temporary storage cavity 1202 are connected through. One side of the upper end of the temporary storage cavity 1202 is provided with a second cavity 1207. The inside of the second cavity 1207 and the inside of the temporary storage cavity 1202 are connected through. The inside of the first cavity 1203 is connected with a first spring 1204. The upper end of the first spring 1204 is connected with an S-shaped baffle plate 1205. The S-shaped baffle plate 1205 is provided with a through hole 1206. The upper end of one side of the S-shaped baffle plate 1205 is connected with a second spring 1208. One end of the second spring 1208 is connected inside the second cavity 1207. The lower end of the temporary storage cavity 1202 is provided with a movable column 1209. The upper end of the movable column 1209 abuts against the lower end surface of the S-shaped baffle plate 1205. The lower end of the movable column 1209 penetrates the inner wall of the temporary storage cavity 1202, and the lower end surface of the movable column 1209 is in contact with the upper end surface of the fixed column 13. The lower end of the temporary storage cavity 1202 is provided with a movable hole. The movable hole is provided with a sealing ring around it. The movable column 1209 penetrates the movable hole at the lower end of the temporary storage cavity 1202. The movable column 1209 moves vertically in the movable hole. The upper end of the oil storage tank 1201 is also provided with an oil inlet. The user pours lubricating oil into the oil storage tank 1201 through the oil inlet.

[0044] When the oil outlet mechanism 12 is inserted into the secondary support frame 14, the fixed column 13 pushes the movable column 1209 upward, the movable column 1209 pushes the S-shaped baffle plate 1205 upward, one end of the S-shaped baffle plate 1205 moves upward from the first cavity 1203 to the inside of the temporary storage cavity 1202, the first spring 1204 is elongated by the upward tension of the S-shaped baffle plate 1205, and the second spring 1208 is contracted by the upward thrust of the S-shaped baffle plate 1205. At this time, the S-shaped baffle plate 1205 separates the space inside the temporary storage cavity 1202, so that the lubricating oil in the oil storage tank 1201 no longer flows into the temporary storage cavity 1202. The state of the internal structure of the temporary storage cavity 1202 is shown in Figure 9 During the upward movement of the S-shaped baffle plate 1205, the through hole 1206 allows the lubricating oil inside the S-shaped baffle plate 1205 to gradually flow outward through the oil outlet pipe 1210, avoiding the phenomenon of extrusion and backflow of lubricating oil when the S-shaped baffle plate 1205 moves upward.

The lubricating oil lubricates between the cross beam 2 and the top column 5, making it convenient to repair and disassemble the cross beam 2 and the top column 5.

[0045] When the oil outlet mechanism 12 is detached from the secondary support frame 14, the fixed column 13 no longer extrudes the movable column 1209, and the movable column 1209 moves downward under its own gravity. The contraction force of the first spring 1204 in the first cavity 1203 pulls the S-shaped shielding plate 1205 downward, and the extension force of the second spring 1208 in the second cavity 1207 pushes the S-shaped shielding plate 1205 downward. Finally, one end of the S-shaped shielding plate 1205 separates the space between the temporary storage cavity 1202 and the oil outlet pipe 1210. At this time, the state of the internal structure of the temporary storage cavity 1202 is as shown in Figure 10 The lubricating liquid in the oil storage tank 1201 enters the temporary storage cavity 1202, and the temporary storage cavity 1202 temporarily stores the lubricating liquid for the next lubrication operation. The oil outlet mechanism 12 uses only the lubricating liquid in the temporary storage cavity 1202 for each lubrication operation, avoiding the waste caused by the continuous outflow of the lubricating liquid in the temporary storage cavity 1202.

The support column (301) is movably set in the groove (11) of the bottom support frame (9).

8. A method for repairing and reinforcing a timber-framed house, the method being applicable to the repair and reinforcement device for a timber-framed house as described in claim 7, characterized in that... Includes the following steps: Step A: The construction workers place the jack (8) on the top of the base block (10), and insert the support column (301) in the support frame (3) into the slide groove (11) on the upper side of the bottom support frame (9). The output end of the jack (8) provides vertical support for the support column (301), in which the support column (301) moves vertically along the slide groove (11). Step B: Next, insert the plug (403) at the lower end of the connecting secondary frame (402) into the positioning groove (303) at the upper end of the front positioning block (302), assemble the fixing frame (7) at the upper end of the rear positioning block (304), and snap the second snap piece (704) at the lower end of the second fixing frame (701) into the groove (305) at the lower end of the rear positioning block (304), so that the first fixing frame (404) and the second fixing frame (701) cover the surface of the support column (301); Step C: Insert the first pin (602) on the front side of the lower end of the top block (601) into the first slot (405), insert the second pin (604) into the rear slot (406) and the front slot (703), and insert the first pin (602) on the rear side of the lower end of the top block (601) into the second slot (702), so that the snap-fit ​​structure (6) snaps into the connecting main frame (401) and the second fixing frame (701), and then the connecting structure (4) connects the two supporting structures (3); Step D: The construction workers operate the jack (8). The output end of the jack (8) pushes the support column (301) upward. The support column (301) moves upward along the slide (11). The top support frame (307) at the top of the support column (301) continuously presses the crossbeam (2), eventually causing the crossbeam (2) and the top column (5) to separate. The construction workers then replace the old top column (5). Step E: If it is difficult to disassemble the crossbeam (2) and the top column (5), insert the oil outlet mechanism (12) into the secondary support frame (14) at the upper end of the main frame (401). The fixed column (13) pushes the movable column (1209) upward, and the movable column (1209) pushes the S-shaped baffle (1205) upward. One end of the S-shaped baffle (1205) moves upward from the first cavity (1203) to the interior of the temporary storage cavity (1202). Then, the S-shaped baffle (1205) temporarily... The internal space of the storage chamber (1202) is separated, so that the lubricating oil inside the oil tank (1201) no longer flows into the temporary storage chamber (1202). Instead, the lubricating oil inside the temporary storage chamber (1202) flows into the oil outlet pipe (1210) through the through hole (1206). The oil outlet pipe (1210) is aligned with the gap between the crossbeam (2) and the top column (5), so that the lubricating oil flows into the gap between the crossbeam (2) and the top column (5) and lubricates it, which facilitates the repair and disassembly of the crossbeam (2) and the top column (5).
