Description

Technical Field

[0001] The present invention relates to the field of ancient building renovation, and particularly to a temporary reinforcement structure for ancient building renovation. Background Art

[0002] The beam nodes in the wooden framework of ancient buildings are the core structures bearing the weight of the roof. However, due to long-term loads, material aging, foundation settlement, and environmental erosion, problems such as cracking are likely to occur, which in turn leads to a reduction in their mechanical properties and seriously affects the structural stability. In renovation projects, due to the long construction time and inevitable construction disturbances, temporarily reinforcing the beams with reduced mechanical properties due to cracking, material aging, etc. is a key step in protective construction. Due to the particularity of ancient buildings, some invasive reinforcement methods are not applicable, such as destructive operations like drilling holes and injecting glue. It is necessary to completely preserve the components of ancient buildings. Therefore, it is necessary to design a temporary reinforcement structure for ancient building renovation to temporarily reinforce ancient buildings in a non-invasive reinforcement manner, thereby increasing the stability of ancient buildings during the renovation process. Summary of the Invention

[0003] The purpose of the present invention is to provide a temporary reinforcement structure for ancient building renovation to overcome the above-mentioned defects in the prior art.

In the above technical solution, the covering mechanism includes four edge-covering components and four tightening components. The four edge-covering components are respectively wrapped around the four edges of the ancient building beam parallel to its length direction, and the four tightening components are respectively located between adjacent two edge-covering components. The tightening component is used to adjust the distance between the four edge-covering components. In the above technical solution, a driving component for driving the tightening or opening of the tightening component is detachably connected to the tightening component.

[0005] In the above technical solution, the edge-covering component includes a covering plate, which is composed of a horizontal part and a vertical part and is in an "L" shape. The connection between the horizontal part and the vertical part of the covering plate fits the edge of the ancient building beam, and the covering plate is attached to the surface of the ancient building beam. Convex strips parallel to the length direction of the ancient building beam are fixedly provided on both the horizontal part and the vertical part of the covering plate. Clamping plates parallel to the horizontal part and the vertical part of the covering plate are respectively fixedly provided on the two convex strips. A clamping groove is formed between the clamping plate and the covering plate, and embedding strips are fixedly provided on the surfaces of the clamping plate and the covering plate that are close to each other.

[0006] In the above technical solution, a number of reinforcing rib plates are fixedly arranged on the outer surface of the covering plate. The reinforcing rib plates straddle the connection between the horizontal part and the vertical part of the covering plate. The reinforcing rib plates are perpendicular to the length direction of the covering plate, and both ends of the reinforcing rib plates are fixedly connected to two covering plates respectively.

[0007] In the above technical solution, a through cavity penetrating along the length direction parallel to the covering plate is formed in the convex strip. The number of the connecting rods is eight, and the connecting rods penetrate through the through cavities on adjacent covering mechanisms.

[0008] In the above technical solution, the converging assembly includes two symmetrically arranged converging rods. Between the two converging rods, there are two symmetrically arranged threaded blocks. The threaded blocks are arranged perpendicular to the converging rods. There are hinge rods rotatably connected between both ends of the threaded blocks and the adjacent converging rods. Between the two converging rods, there is a screw rod passing through the two threaded blocks. The screw rod is threadedly connected to the two threaded blocks. The thread directions in the two threaded blocks are opposite. Two symmetrically arranged fitting grooves are formed on the converging rods. The converging rods can be embedded into the clamping grooves. The inlay strips are embedded into the fitting grooves. The hinge rods rotate in the clamping grooves. The height of the clamping grooves is the same as the thickness of the hinge rods.

[0009] In the above technical solution, synchronous heads are fixedly arranged at both ends of the screw rod. Synchronous sleeves are arranged between the two opposite synchronous heads of adjacent covering mechanisms. A through hole with the same cross-section as the synchronous head is formed in the synchronous sleeve. The synchronous head can be fitted into the through hole of the synchronous sleeve.

[0010] In the above technical solution, a driven gear is fixed in the middle of the screw rod. A slider is fixed on the side of the threaded block away from the ancient building cross beam. A bolt is fixed on the slider. The driving mechanism includes a connecting plate, a gear box and a motor. A guiding groove recessed towards the threaded block is formed on the side of the connecting plate away from the threaded block. The gear box is fixed in the guiding groove. The lower end of the gear box is open. A driving gear is rotatably connected in the gear box. The driving gear can be meshed with the driven gear. The motor is fixed on the gear box.

[0012] The beneficial effects of the present invention are as follows: The present invention wraps the four edges of the crossbeam of the ancient building with the edge wrapping components. Two opposite motors are started simultaneously, so that the two relatively arranged screws rotate simultaneously, and then the four edge wrapping components tightly wrap the position where the crossbeam of the ancient building has cracks. If the crack of the crossbeam is relatively long, multiple wrapping mechanisms can be wrapped on the crossbeam. Eight connecting rods pass through the through grooves on the multiple wrapping mechanisms, thereby increasing the bending resistance between adjacent wrapping mechanisms. The present invention uses a non-invasive reinforcement method to wrap and reinforce the cracked crossbeam of the ancient building, thereby increasing the stability of the ancient building during subsequent renovation.

DETAILED DESCRIPTION OF THE INVENTION

[0015] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the attachedFigure 1 The orientation or positional relationship shown is only a simplified description for facilitating the description of the present invention, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0016] In order to make the purpose and advantages of the present invention more clear and understandable, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms "up and down" and "left and right" are not limited to their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent. The specific features of a temporary reinforcement structure for ancient building repair will be described in detail below: An embodiment of the present invention: Referring to Figures 1 - 9 , the present invention provides a temporary reinforcement structure for ancient building repair, including a plurality of covering mechanisms that can be wrapped around the cross beam of an ancient building. A plurality of connecting rods 50 are connected between the plurality of covering mechanisms, and the connecting rods 50 penetrate through the plurality of covering mechanisms to increase the bending strength between adjacent covering mechanisms; The covering mechanism includes four edge covering components and four converging components 2. The four edge covering components are respectively wrapped around the four edge sides of the ancient building cross beam parallel to its length direction, and the four converging components 2 are respectively located between two adjacent edge covering components. The converging component 2 is used to adjust the distance between the four edge covering components; A driving component 4 for driving the converging or opening of the converging component 2 is detachably connected to the converging component 2.

[0017] Referring to Figure 8 , the edge covering component includes a covering plate 14. The covering plate 14 is composed of a horizontal part and a vertical part and is in an "L" shape. The connection part between the horizontal part and the vertical part of the covering plate 14 is attached to the edge side of the ancient building cross beam. The covering plate 14 is attached to the surface of the ancient building cross beam. Ribs 12 parallel to the length direction of the ancient building cross beam are fixedly provided on both the horizontal part and the vertical part of the covering plate 14. Clamping plates 11 parallel to the horizontal part and the vertical part of the covering plate 14 are fixedly provided on both ribs 12. A clamping groove 17 is formed between the clamping plate 11 and the covering plate 14. Embedding strips 16 are fixedly provided on the mutually approaching surfaces of the clamping plate 11 and the covering plate 14. The edge covering components are all made of aluminum alloy material. The edge covering components are wrapped around the edge sides of the ancient building, which can not only ensure the fixed position of the edge covering components, but also ensure the covering effect of the edge covering components on the ancient building cross beam.

[0018] Referring to Figure 8, a number of reinforcing rib plates 13 are fixedly arranged on the outer surface of the covering plate 14. The reinforcing rib plates 13 straddle the connection part between the horizontal part and the vertical part of the covering plate 14. The reinforcing rib plates 13 are perpendicular to the length direction of the covering plate 14. Both ends of the reinforcing rib plates 13 are fixedly connected to two covering plates 14 respectively. The arrangement of the reinforcing rib plates 13 increases the strength of the bent part of the covering plate 14.

[0019] Refer to Figure 2 , Figure 8 , Figure 9 , a through cavity 15 running through in the direction parallel to the length of the covering plate 14 is formed in the protruding strip 12. The number of connecting rods 50 is eight. The connecting rods 50 are made of I-beams. The connecting rods 50 penetrate through the through cavities 15 on adjacent covering mechanisms. After the connecting rods 50 pass through a plurality of through cavities 15, the bending resistance strength between adjacent covering mechanisms can be increased, so that the arrangement of a plurality of covering mechanisms can not only extend the covering area of the cross beam, but also ensure the reinforcement and protection effect of a plurality of covering mechanisms on the cross beam.

[0020] Refer to Figure 4 , Figure 8 , the converging component 2 includes two symmetrically arranged converging rods 21. Between the two converging rods 21, two symmetrically arranged threaded blocks 23 are provided. The threaded blocks 23 are arranged perpendicular to the converging rods 21. Hinge rods 22 are rotatably connected between both ends of the threaded blocks 23 and the adjacent converging rods 21. A screw rod 20 passing through the two threaded blocks 23 is arranged between the two converging rods 21. The screw rod 20 is threadedly connected with the two threaded blocks 23. The thread directions in the two threaded blocks 23 are opposite. Two symmetrically arranged fitting grooves 26 are formed on the converging rods 21. The converging rods 21 can be embedded into the clamping grooves 17. The inserting strips 16 are embedded into the fitting grooves 26. The fitting of the inserting strips 16 and the fitting grooves 26 makes the connection between the converging component 2 and the covering component detachable, which is convenient for the disassembly and assembly of the two. After the two are installed together, the inserting strips 16 are embedded into the fitting grooves 26, which can ensure the connection strength between the converging component 2 and the covering component. The hinge rods 22 rotate in the clamping grooves 17. The height of the clamping grooves 17 is the same as the thickness of the hinge rods 22. The setting of the clamping plates 11 makes the clamping grooves 17 formed between the clamping plates 11 and the covering plate 14 for accommodating part of the converging component 2. At the same time, the clamping plates 11 provide a supporting force for the hinge rods 22 during the rotation process of the hinge rods 22, ensuring that the hinge rods 22 remain stable during the rotation process and avoiding the situation that the converging component 2 gets stuck.

[0021] Refer to Figure 2 , Figure 3, synchronous heads 24 are fixedly installed at both ends of the screw rod 20. The synchronous heads 24 are regular hexagonal prisms. Synchronous sleeves 30 are arranged between the two relatively positioned synchronous heads 24 of adjacent two covering mechanisms. Through holes with the same cross-section as the synchronous heads 24 are formed in the synchronous sleeves 30. The cross-section of the through holes is a regular hexagon. The synchronous heads 24 can be fitted into the through holes of the synchronous sleeves 30. The arrangement of the synchronous sleeves 30 enables the relatively positioned screw rods 20 between multiple covering mechanisms to rotate synchronously, thus facilitating the synchronous covering and fixing of multiple covering mechanisms on the cross beam.

[0022] Refer to Figures 4 - 7 , a driven gear 25 is fixed in the middle of the screw rod 20. A slider 28 is fixed on the side of the threaded block 23 away from the ancient building cross beam. A bolt 27 is fixed on the slider 28. The driving assembly 4 includes a connecting plate 40, a gear box 42 and a motor 41. A guiding groove 45 recessed towards the side close to the threaded block 23 is formed on the side of the connecting plate 40 away from the threaded block 23. The gear box 42 is fixed in the guiding groove 45. The gear box 42 has an opening at the lower end. A driving gear 48 is rotatably connected in the gear box 42. The driving gear 48 can be engaged with the driven gear 25. The driven gear 25 can be set as a cylinder, and the length of the tooth shape on its outer periphery in the axial direction of the screw rod 20 is extended, so that even when the driving gear 48 moves in the axial direction of the screw rod 20, the driving gear 48 can still maintain the meshing state with the driven gear 25. The motor 41 is fixed on the gear box 42. The two relatively positioned motors 41 are synchronously controlled by a single-chip microcomputer, that is, the motors 41 on the upper and lower sides rotate and stop simultaneously, and the same applies to the motors 41 on the left and right sides. The driving gear 48 is fixedly connected with the output shaft of the motor 41.

[0023] Refer to Figure 5 , Figure 7 , two symmetrically arranged through grooves 46 distributed at both ends of the connecting plate 40 are formed on the bottom wall of the guiding groove 45. The two sliders 28 can slide in the two through grooves 46 respectively. The bolt 27 penetrates through the through groove 46 and the guiding groove 45. Two guiding blocks 47 are slidably connected in the guiding groove 45. The two bolts 27 penetrate through the two guiding blocks 47 respectively. Nuts 43 that can abut against the guiding blocks 47 are threadedly connected on the bolts 27. A spring piece 44 is fixedly connected between the guiding block 47 and the side wall of the guiding groove 45 away from the gear box 42. Since the distance between the two threaded blocks 23 will change when the screw rod 20 rotates, the gear box 42 can be kept at the middle position between the two threaded blocks 23 under the elastic force or tensile force of the two spring pieces 44, thereby ensuring that the driving gear 48 can always maintain the meshing state with the driven gear 25.

[0024] When the present invention is in use, the two uppermost wrapping edge components are respectively placed on the cross beam, the bundling component 2 is placed between the two wrapping edge components, the relative positions of the three are adjusted, and the two fitting grooves 26 are embedded into the corresponding fitting strips 16.

[0025] Then, connect the wrapping edge component on the lower left side to the wrapping edge component on the upper left side through the converging component 2, and connect the wrapping edge component on the lower right side to the wrapping edge component on the lower right side through the converging component 2. Rotate the screws 20 on the left and right sides to adjust the relative height of the two wrapping edge components on the lower side. Finally, connect the two wrapping edge components on the lower side to each other through the converging component 2.

[0026] Move the assembled covering mechanism along the cross beam to the crack. If the crack length is relatively long, then according to the crack length, repeat the above process to install multiple covering mechanisms. Eight synchronous sleeves 30 are arranged between adjacent covering mechanisms. The two ends of the synchronous sleeve 30 are respectively sleeved on the two adjacent synchronous heads 24, so that the two opposite screws 20 on the adjacent covering mechanisms can rotate synchronously.

[0027] Install the four driving components 4 on the four converging components 2 respectively. The connecting plate 40 is attached to the two threaded blocks 23. The two bolts 27 and the slider 28 both pass through the through slot 46. The slider 28 is embedded in the through slot 46 and can slide along the through slot 46. After placing the guiding block 47 into the through slot 46, the bolt 27 passes through the guiding block 47, and the nut 43 is sleeved on the bolt 27. Rotate the nut 43 so that the guiding block 47 just abuts against the bottom wall of the guiding slot 45. The nut 43 is used to limit the guiding block 47 to prevent the guiding block 47 from falling off the bolt 27. The spring piece 44 is clamped between the guiding block 47 and the side wall of the guiding slot 45. At this time, the driving gear 48 meshes with the driven gear 25.

[0028] At this time, start the motors 41 on the upper and lower sides simultaneously, so that the screws 20 on the upper and lower sides rotate synchronously, thereby driving the corresponding threaded blocks 23 to move away from the driven gear 25, and further making the two converging rods 21 on both sides approach each other in the middle, so that the wrapping edge components on the left and right sides approach each other, then making the covering mechanism narrow in the horizontal direction. When the vertical part of the covering plate 14 abuts against the side surface of the cross beam, turn off the motors 41 on the upper and lower sides.

[0029] Then, start the motors 41 on the left and right sides simultaneously, so that the covering mechanism narrows in the vertical direction until the covering mechanism is closely attached to the cross beam in the vertical direction, and then turn off the motors 41 on the left and right sides.

[0030] Finally, restart the motors 41 on the upper and lower sides, so that the covering mechanism is closely attached to the cross beam in the horizontal direction. In this way, the covering mechanism wraps and fixes the ancient building cross beam.

[0031] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. They all fall within the protection scope of the present invention. The protection scope of the present invention is subject to the appended claims of the present invention.
