[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] Reference Figures 1 to 6 This invention discloses a protective device for ancient wooden structures in architectural cultural heritage, comprising:

[0053] The first connecting structure is fixedly connected to column 1;

[0054] The second connecting structure is fixedly connected to the crossbeam 13, and the second connecting structure is fixedly connected to the first connecting structure.

[0055] The tension structure is set at both ends on the two adjacent first connecting structures, and the middle of the tension structure is connected to the middle of the crossbeam 13.

[0056] The tension structure includes a tension cable 5, with two first tension components connected to both ends of the tension cable 5. The two first tension components are respectively set on two adjacent first connection structures. A second tension component is connected to the middle of the tension cable 5, and the second tension component is set in the middle of the crossbeam 13.

[0057] In use, the first connecting structure is fixedly connected to the column 1, and the second connecting structure is fixedly connected to the crossbeam 13. The first connecting structure and the second connecting structure are fixedly connected, and the weight of the crossbeam 13 at the connection between the crossbeam 13 and the column 1 is borne by the first connecting structure and the second connecting structure, thereby protecting the crossbeam 13 in the wooden ancient building.

[0058] A tension cable 5 is installed between the two first connecting structures on two adjacent columns 1. A second tension component is installed in the middle of the tension cable 5. The second tension component is located in the middle of the crossbeam 13, thereby providing tension to the middle of the crossbeam 13 and preventing the middle of the crossbeam 13 from bending downward under the action of gravity.

[0059] The device of the present invention can provide good protection for the beams 13 of ancient wooden buildings.

[0060] The scheme is further optimized so that the first connection structure includes two first connection components arranged symmetrically at the top and bottom, respectively located on the top and bottom sides of the crossbeam 13;

[0061] The first connecting component includes: two first guard plates 2, the first guard plates 2 are configured in the shape of a c, the openings of the two first guard plates 2 are arranged opposite each other, the first guard plates 2 are sleeved on the outside of the column 1, and the two first guard plates 2 are fixedly connected by bolts 18.

[0062] Two connecting plates 3 are circumferentially fixed to the outside of the first protective plate 2. Multiple connecting plates 3 on the two first connecting components located on the same column 1 are arranged close to each other. Screw holes 19 are opened at the corners of the connecting plates 3.

[0063] The stud 4 is inserted into two stud holes 19 that are opposite each other on two adjacent connecting plates 3, and the two adjacent connecting plates 3 are fixedly connected by the stud 4.

[0064] The two C-shaped first protective plates 2 are fitted onto the column 1 and fixedly connected by bolts 18. Then, the two adjacent first connecting components are fixedly connected by studs 4, thereby fixing the first connecting structure on the column 1. At the same time, the crossbeam 13 is set between the two adjacent connecting plates 3, and the connecting plates 3 play a certain supporting and fixing role for the crossbeam 13.

[0065] Further optimization of the design: The first tension component includes:

[0066] Two tension plates 11 are hinged to the top surface of the connecting plate 3 located above by the first hinge seat 20. The two tension plates 11 are located on opposite sides of the first guard plate 2. The two ends of the tension cable 5 are respectively connected to the tension plates 11 on the two adjacent columns 1. The connection between the tension cable 5 and the tension plate 11 is located at the upper part of the tension plate 11.

[0067] The tension adjustment mechanism is located between the tension plate 11 and the connecting plate 3.

[0068] The upper part of the tension plate 11 has a cable hole 22, which is truncated cone-shaped. A locking block 31 is inserted through the cable hole 22. The locking block 31 is truncated cone-shaped and has a through hole. The tension cable 5 is inserted through the through hole. The end of the tension cable 5 passes through the large end of the locking block 31 and is fixedly connected to a locking ring 30.

[0069] The locking block 31 has multiple locking grooves 32, which are evenly spaced around the perimeter.

[0070] When the tension cable 5 generates tension, it pulls the locking ring 30, which abuts against the large end of the locking block 31. The small end of the locking block 31 is located inside the cable hole 22. As the tension of the tension cable 5 increases, the locking block 31 moves into the cable hole 22 under the action of tension. At this time, the locking groove 32 shrinks under the action of tension, and the locking force of the locking block 31 on the tension cable 5 increases, preventing the tension cable 5 from separating from the tension plate 11.

[0071] The design has been further optimized, and the tension adjustment mechanism includes:

[0072] The first threaded rod 34 is hinged to one side of the tension plate 11 via the third hinge seat 23;

[0073] The second threaded rod 35 is hinged to the top surface of the connecting plate 3 via the second hinge seat 21, and the thread of the second threaded rod 35 is reversed with the thread of the first threaded rod 34.

[0074] The threaded tube 36 is threaded at both ends to the first threaded rod 34 and the second threaded rod 35, respectively.

[0075] Rotating the threaded tube 36 causes the first threaded rod 34 and the second threaded rod 35 to move away from or towards each other, thereby increasing or decreasing the tension of the tension cable 5.

[0076] The second tension component, further optimized, includes:

[0077] The fixing frame 14 is fitted onto the outside of the crossbeam 13, and the fixing frame 14 is located in the middle of the crossbeam 13.

[0078] Two connecting rods 15 are fixed to the top of the fixed frame 14 and located on opposite sides of the fixed frame 14;

[0079] The tension ring 16 is fixed to the end of the connecting rod 15 away from the fixed frame 14, and the tension cable 5 is inserted through the tension ring 16 at the middle.

[0080] The tension cable 5 is threaded inside the tension ring 16. When the tension cable 5 is tensioned, it provides tension to the tension ring 16, thereby providing tension to the fixed frame 14. This provides tension to the middle of the crossbeam 13, preventing the middle of the crossbeam 13 from bending downwards under the action of gravity, which would cause the crossbeam to deform and crack.

[0081] Further optimizing the design, the second connection structure includes two second connection components, which are respectively disposed on the upper and lower sides of the crossbeam 13 and arranged opposite to each other. The second connection components include:

[0082] The second guard plate 12 is configured as an incline and covers the outside of the crossbeam 13.

[0083] Mounting plate 29, one end is fixedly connected to the second guard plate 12, and the other end is fixedly connected to the connecting plate 3;

[0084] The thrust adjustment mechanism is fixedly connected to the mounting plate 29;

[0085] The thrust mechanism is connected to the thrust adjustment mechanism at one end and hinged to the mounting plate 29 at the other end. The hinge point between the thrust mechanism and the mounting plate 29 is close to the second guard plate 12.

[0086] The second guard plate 12 is fixed to the connecting plate 3 via the mounting plate 29, and the second guard plate 12 covers the outside of the crossbeam 13. With this arrangement, the second guard plate 12 bears part of the weight of the connection of the crossbeam 13, protecting the connection between the crossbeam 13 and the column 1. The setting of the thrust adjustment mechanism and the thrust mechanism increases the tightness of the connection between the second guard plate 12 and the crossbeam 13, and further distributes the weight of the connection of the crossbeam 13 to the connecting plate 3.

[0087] The design has been further optimized, and the thrust adjustment mechanism includes:

[0088] Two fixed plates 8 are arranged in parallel and symmetrically. A fixed block 9 is fixed between the top ends of the two fixed plates 8. A vertically arranged sliding groove 25 is provided on the fixed plate 8.

[0089] A threaded block 26 is disposed between two fixed plates 8, with a gap between the threaded block 26 and the fixed plate 8. Slide rods 24 are fixedly connected to opposite sides of the threaded block 26, and the two slide rods 24 are slidably connected in the two slide grooves 25.

[0090] The screw 7 is threadedly connected to the fixing block 9. The top end of the screw 7 passes through the fixing block 9 and is coaxially fixed to the knob 6. The bottom end of the screw 7 passes through the fixing block 9 and is threadedly connected to the threaded block 26.

[0091] The design has been further optimized, and the thrust mechanism includes:

[0092] Push rod 10, one end of which is hinged to mounting plate 29, and the hinge point between push rod 10 and mounting plate 29 is close to the second guard plate 12;

[0093] Sleeve 27 is fixed to the other end of push rod 10 and slidably connected to the outside of slide rod 24. Sleeve 27 is located between threaded block 26 and fixed plate 8.

[0094] With this configuration, turning the knob 6 with a wrench causes the screw 7 to rotate, which in turn causes the threaded block 26 to move downward. The downward movement of the threaded block 26 causes the slide bar 24 to move downward within the slide groove 25, which in turn causes the sleeve 27 to move downward. The downward movement of the sleeve 27 causes the push rod 10 to apply a small amount of pressure to the mounting plate 29, thereby increasing the pressure at the connection between the second guard plate 12 and the crossbeam 13. The mounting plate 29 is a metal plate, and it can deform under external force.

[0095] In a further optimized design, a flexible pad 37 is bonded to one side of the inner bottom wall of the first protective plate 2, and a rigid contact layer 38 is bonded to the other side of the flexible pad 37. Multiple pits 39 are formed on the side of the rigid contact layer 38 away from the flexible pad 37, and the multiple pits 39 are distributed in an array.

[0096] The flexible pad 37 is preferably a rubber layer, and the hard contact layer 38 is preferably a wood board. The hard contact layer 38 has a certain degree of softness and will not damage the column 1. The recess 39 is designed to increase the friction between the hard contact layer 38 and the column 1.

[0097] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0098] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
