Description

Technical Field

[0001] The invention relates to the technical field of building restoration, and more particularly to an adjustable reinforcement device for restoring ancient buildings. Background Art

[0002] Ancient buildings refer to civil and public buildings with historical significance before the founding of the People's Republic of China, including buildings from the Republic of China period. In China, many ancient towns and most large cities still retain some ancient buildings. In today's era of large-scale construction, we must protect ancient buildings and the cultural characteristics they contain, so that the ancient architectural culture can be preserved in the world. The structure of ancient buildings is usually composed of wooden columns, beam-column frames, etc. Unlike steel and concrete structures, wooden structures determine their insufficient bearing capacity. After natural disasters such as strong winds, snow and snow, as well as the accumulation of time, coupled with the defects of the wood itself, the overall structure has insufficient bearing capacity and reduced rigidity. Many wooden columns will have cracks and insufficient bearing capacity, and there is a risk of breakage, so it is often necessary to reinforce and protect the damaged parts.

[0003] Chinese invention patent publication number CN112196304A discloses a reinforcement and protection device for the restoration of ancient buildings, comprising two protective tubes, the side walls of the two protective tubes are fixedly installed with connecting plates, a tensioning mechanism is installed between the connecting plates, the top and bottom of the outer wall of the protective tube are integrally formed with outer flanges, a plurality of mounting shells are evenly clamped between the outer flanges along the circumferential direction of the protective tube, a reinforcement mechanism is installed between the inner cavity of the mounting shell and the outer flange, the protective tube is tightened and fixed on the column by the tensioning mechanism, so as to provide auxiliary support for the damaged part, and the rubber pad is used to avoid pinching the intact part of the column, and then the reinforcement mechanism is installed between the outer flanges through the mounting shell to prevent the column from tilting outward and collapsing, thereby improving the reinforcement strength.

[0004] However, the above device still has shortcomings. Since the size of the protective tube of the device is fixed, it can only reinforce wooden columns of a specific diameter. When reinforcing different wooden columns, it is necessary to process protective tubes of corresponding sizes, which is labor-intensive and has low reinforcement efficiency, and also increases costs. If the diameter of the reinforced wooden column and the protective tube cannot be well matched and adapted, the contact area between the protective tube and the wooden column will be greatly reduced, which greatly reduces the reinforcement and supporting effect of the wooden column, and ultimately affects the restoration effect of the ancient building.

[0005] Therefore, it is necessary to provide an adjustable reinforcement device for repairing ancient buildings to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide an adjustable reinforcement device for repairing ancient buildings to solve the problem proposed in the above-mentioned background technology that the size of the protective tube of the device is fixed and can only reinforce wooden columns of a specific diameter.

The reinforcement effect is good, and there is no need to process reinforcement devices of various sizes.

The transmission rod 603 will drive multiple second rope winding wheels 604 to rotate, and the second rope winding wheels 604 can tighten or relax the traction rope 503. When the second rope winding wheel 604 on the left transmission rod 603 drives the traction rope 503 to tighten / relax, the second rope winding wheel 604 on the right transmission rod 603 drives the traction rope 503 to relax / tighten. The movement of the traction rope 503 will drive the first rope winding wheel 502 to rotate through the rotation of the steering wheel 10 and the first through hole 8.

After the wooden column is located between each reinforcing inner arc plate 2, the first mounting block 20 on the lower reinforcing outer arc plate 1 now corresponds to the position of the second mounting block 21 on the upper reinforcing outer arc plate 1. First, pull the pull block 27 outward, and the pull block 27 will drive the limit rod 26 to move outward and stretch the first spring 28, eventually causing the limit rod 26 to leave the slot 24. Then, insert the plug plate 22 of the first mounting block 20 into the slot 24 of the second mounting block 21, and then release the pull block 27.

Figure 1 and Figure 4 As shown, the two reinforced outer arc plates 1 can be simply and conveniently installed, fixed and disassembled, avoiding the situation where the bolts will rust and loosen and vibrate out, thereby improving the reinforcement and stabilization effect of the building.

[0047] Embodiment 4:

[0048] See also Figure 12-16On the basis of the first embodiment and distinguished from the third embodiment, the fixing assembly includes a lower guide cavity 30 and a limiting hole 31 opened inside the first mounting block 20, an insert block 32 is fixedly connected to the outer wall of the first mounting block 20, an upper guide cavity 33 communicating with the lower guide cavity 30 is opened inside the insert block 32, a fixed plug rod 34 is slidably connected to the inner wall of the upper guide cavity 33, a second spring 35 is fixedly connected between the fixed plug rod 34 and the inner wall of the upper guide cavity 33, an insertion cavity 36 and a T-shaped cavity 37 communicating with each other are opened inside the second mounting block 21, a wedge block 38 is slidably connected to the inner wall of the T-shaped cavity 37, a fixed vertical rod 39 movably penetrating the second mounting block 21 is fixedly connected to the lower end of the wedge block 38, and the lower end of the wedge block 38 is fixedly connected to the inner wall of the T-shaped cavity 37 A third spring 40 is connected, and a trigger accessory is provided on the reinforced outer arc plate 1 and the reinforced inner arc plate 2 to make the first mounting block 20 and the second mounting block 21 cooperate and fix. The trigger accessory includes a plurality of air bags 43 installed on the concave outer wall of the reinforced inner arc plate 2. A connecting cavity 41 and a transfer cavity 42 are respectively provided inside the reinforced outer arc plate 1 and the reinforced inner arc plate 2. The concave wall of the reinforced inner arc plate 2 is provided with a plurality of first openings connecting the air bags 43 and the transfer cavity 42. The telescopic rod 3 includes a hollow outer rod and a hollow inner rod slidably connected to the inner wall of the hollow outer rod. The convex wall of the reinforced inner arc plate 2 is provided with a second through hole communicating with the inside of the hollow inner rod. The inner wall of the reinforced outer arc plate 1 is provided with a third through hole communicating with the hollow outer rod. The connecting cavity 41 is connected to the lower guide cavity 30. When in use, when the two reinforcing outer arc plates 1 are placed on the wooden columns to be reinforced respectively, the insert blocks 32 on the first mounting blocks 20 on both sides are inserted into the inserting cavities 36 on the second mounting blocks 21, and then the reinforcing inner arc plates are gradually approached to the wooden columns through the transmission mechanism 6. At this time, the airbag 43 will contact the wooden column. The airbag can adapt well to the outer surface of the wooden column and has a good fitting effect with the wooden column, which can greatly improve the effect of avoiding reinforced support of the wooden column.At the same time, as the reinforced inner arc plate and the wooden column continue to approach each other, the wooden column will squeeze the airbag 43, and the gas in the airbag 43 will squeeze the gas into the transfer cavity 42 of the reinforced inner arc plate through the first through hole, and then enter the telescopic rod 3 through the second through hole, and then enter the connecting cavity 41 of the reinforced outer arc plate 1 through the third through hole, and then enter the lower guide cavity 30 and the upper guide cavity 33. The gas in the upper guide cavity 33 will squeeze the fixed plug rod 34 to move and compress the second spring 35. The fixed plug rod 34 will move outward and gradually enter the T-shaped cavity 37, thereby realizing the vertical fixation of the first mounting block 20 and the second mounting block 21. If the contact between the air bag 43 and the wooden column is continued to be increased, so that the fixing effect of the wooden column is better, the fixing rod 34 will continue to move into the T-shaped cavity 37. At this time, the fixing rod 34 will drive the wedge block 38 to slide toward the T-shaped cavity 37 and compress the third spring 40. The wedge block 38 will drive the fixing vertical rod 39 to move, and the fixing vertical rod 39 will gradually enter the limiting hole 31 of the first mounting block 20, thereby realizing the horizontal fixation of the first mounting block 20 and the second mounting block 21, so as to better enhance the reinforcement effect of the two reinforced outer arc plates 1 on the wooden column, and also enable the reinforced wooden column to be subjected to a greater reinforcement force, and the use effect is good.

[0049] Working principle: When in use, two identical devices are required. The two devices are placed on the outside of the wooden column to be reinforced, so that the wooden column is located between each reinforced inner arc plate 2. At this time, the first mounting block 20 on the lower reinforced outer arc plate 1 corresponds to the second mounting block 21 on the upper reinforced outer arc plate 1. Then, the first mounting block 20 and the second mounting block 21, i.e., the two reinforced outer arc plates 1, can be fixed by the fixing assembly. Figure 1 and Figure 4 shown.

[0050] Then, the rotating disk is rotated to drive the driving rod 11 and the worm 12 to rotate, and the worm 12 will simultaneously drive the worm wheels 13 on both sides and the transmission rod 603 to rotate, and the rotation directions are the same, and the transmission rod 603 will drive multiple second rope winding wheels 604 to rotate, and the rope winding wheels 902 can tighten or relax the traction rope 503. When the second rope winding wheel 604 on the left transmission rod 603 drives the traction rope 503 to tighten / relax, at this time, the second rope winding wheel 604 on the right transmission rod 603 drives the traction rope 503 to relax / tighten, and the movement of the traction rope 503 will drive the first rope winding wheel 502 to rotate through the rotation of the steering wheel 10 and the first through hole 8, and the second rope winding wheel 604 on the left transmission rod 603 drives the traction rope 503 to tighten / relax. The wheel 604 drives the traction rope 503 to tighten or loosen, which will make the first rope wheel 502 rotate forward or reverse, thereby driving the rotating shaft 4 to rotate through the first rope wheel 502. When the rotating shaft 4 rotates, it will drive the movable sleeve 501 to move, and the movable sleeve 501 will drive the reinforced inner arc plate 2 to move along with the extension and retraction of the telescopic rod 3, which will make the reinforced inner arc plates 2 move in the direction of approaching or moving away from each other. At this time, during installation, the reinforced inner arc plate 2 moves toward the direction of the middle wooden column, and finally contacts and fixes it, thereby achieving the reinforcement effect of the building wooden column, and the inner diameter distance between the reinforced inner arc plates 2 can also be adjusted according to the different diameters of the wooden columns to be reinforced.

[0051] When using the device, the adjusting screw 16 can also be rotated. The adjusting screw 16 will drive the connecting plate 17 connected to it to move while rotating. The connecting plate 17 will drive the second wheel frame 18 and the anti-slip wheel 19 to move, so that the anti-slip wheel 19 moves in the direction of the steering wheel 10. The traction rope 503 is located between the anti-slip wheel 19 and the steering wheel 10. When the anti-slip wheel 19 contacts the traction rope 503, the movement of the traction rope 503 will also drive the anti-slip wheel 19 to rotate. The restriction of the traction rope 503 by the anti-slip wheel 19 can prevent the traction rope 503 from detaching from the steering wheel 10 and falling out during the movement. At the same time, after the traction rope 503 has finished moving, the anti-slip wheel 19 can continue to be moved to press the traction rope 503 tightly, so as to prevent the traction rope 503 from detaching later.
