Description

Technical Field

[0001] The invention relates to the technical field of protection of ancient buildings with civil engineering structures, and in particular to a building heritage protection device for civil engineering structures. Background Art

[0002] Ancient buildings are mainly civil structures. Due to the low level of production technology at that time, people had no way to produce large amounts of cement and steel bars to meet people's housing needs. The materials needed for civil structures could be easily obtained, which also made civil structures widely accepted by ancient people.

[0003] Ancient buildings use reasonable structural design to form a mechanical system of mutual support and balance between wood, ensuring the stability and safety of the building. Mortise and tenon structure and mortise and tenon joint technology: Mortise and tenon structure is a common connection method in ancient wooden buildings. It uses grooves (tenons) and convex tenons (mortise) to connect wood together to form a stable structure. The mortise and tenon structure requires precise connection and skilled mortise and tenon joint technology, including chiseling tenons, planing tenons, and inserting tenons. Dougong and dougong structure: Dougong and dougong are common load-bearing structures in ancient wooden buildings. Dougong is formed by bending and combining multiple pieces of wood to form a solid arc structure that can support large loads.

[0004] Ancient buildings are decorated intricately, and the weight of the house is supported by the roof frame consisting of beams and columns. As vertical components, columns play a major role in bearing weight. As time goes by, the foundation of the ancient building gradually sinks, and the columns are the main bearing points, resulting in the largest sinking of the columns, causing deformation at the connection between the columns and beams, and deformation of the entire ancient building.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1-6 As shown, an embodiment of the present invention provides a building heritage protection device for civil structures, comprising three support plates 2, characterized in that: the three support plates 2 are equidistantly distributed in the vertical direction, the same side ends of the three support plates 2 are respectively fixedly connected with a clamping mechanism 1, and the support plate 2 is located in the middle of the side end of the clamping mechanism 1, a jack 4 is installed between two adjacent support plates 2, and the jack 4 is located in the middle of the support plate 2, two telescopic mechanisms 5 are symmetrically provided on both sides of the jack 4, and the upper and lower ends of the telescopic mechanisms 5 are respectively fixedly connected to the two adjacent support plates 2, and the lower end of the bottommost support plate 2 is fixedly connected with two support mechanisms 3, and the support mechanisms 3 are respectively located at the two side ends of the support plate 2.

[0031] The clamping mechanism 1 is composed of a first hoop body 6 and a second hoop body 8. The first hoop body 6 and the second hoop body 8 have the same shape and size, and are symmetrical. An arc groove is provided in the middle of the opposite ends of the first hoop body 6 and the second hoop body 8. One end of the first hoop body 6 is symmetrically fixedly connected with a pair of screw rods 7, and the screw rods 7 are located at one end of the first hoop body 6 facing the second hoop body 8. The end of the screw rod 7 away from the first hoop body 6 passes through the second hoop body 8, and the screw rod 7 is slidably connected to the second hoop body 8. A first nut 9 is provided on the side of the second hoop body 8 away from the first hoop body 6, and the screw rod 7 passes through the middle of the first nut 9 and is threadedly connected to the first nut 9.

[0032] Rubber pads 10 are fixedly connected to the middle of the opposite ends of the first hoop body 6 and the second hoop body 8 respectively, and the surfaces of the rubber pads 10 are provided with anti-slip grooves.

[0033] The surfaces of the clamping mechanism 1, the supporting plate 2, the supporting mechanism 3, the jack 4 and the telescopic mechanism 5 are sprayed with imitation wood grain paint respectively.

[0034] The first hoop body 6 and the second hoop body 8 are brought close to each other by the screw rod 7 in cooperation with the first nut 9, so as to clamp the column and bear part of the pressure on the column. At the same time, the three clamping mechanisms 1 arranged in the device increase the contact surface between the device and the column, and cooperate with the rubber pad 10 to prevent the column from being damaged. The jack 4 connects the three clamping mechanisms 1 so that the force exerted on the three clamping mechanisms 1 is transmitted downward to the ground around the column. The imitation wood grain paint on the surface of the device makes the style of the device the same as that of the ancient building, and integrates with the ancient building as much as possible, reducing the impact on the appearance of the ancient building.

[0035] Embodiment 2:

[0036] The difference between this embodiment and the first embodiment is that:

[0037] The telescopic mechanism 5 is composed of a sleeve 16 and a push rod 19. The lower end of the sleeve 16 is fixedly connected to the support plate 2. The push rod 19 is arranged in the sleeve 16 and is slidably connected to the inner wall of the sleeve 16. The upper end of the push rod 19 passes through the sleeve 16. The upper end of the push rod 19 is fixedly connected to the support plate 2. Two sliding grooves 14 are symmetrically opened at the outer end of the push rod 19. Sliding bars 15 are respectively slidably connected in the two sliding grooves 14, and the sliding bar 15 is fixedly connected to the inner wall of the sleeve 16.

[0038] An adjustment groove 17 is provided in the middle of the outer end of the sleeve 16, and the adjustment groove 17 extends into the sleeve 16. A locking bolt 18 is provided at the outer end of the sleeve 16, and the locking bolt 18 passes through the adjustment groove 17 and is slidably connected to the adjustment groove 17. One end of the locking bolt 18 extends into the push rod 19 and is threadedly connected to the push rod 19.

[0039] The distance between the clamping mechanism 1 is raised by the jack 4, and the push rod 19 extends from the sleeve 16 to ensure the stability of the clamping mechanism 1 when it is raised. After the adjustment of the clamping mechanism 1 is completed, the locking bolt 18 is used to lock the push rod 19 and the sleeve 16 to share the pressure on the jack 4.

[0040] Embodiment 2:

[0041] The difference between this embodiment and the first embodiment is that:

[0042] The supporting mechanism 3 is composed of a supporting frame 11, an adjusting screw 12, a foot 13 and a rotating sleeve 20. The supporting frame 11 is fixedly connected to the lower end of the supporting plate 2. The foot 13 is located at the lower end of the supporting frame 11, and the foot 13 is respectively located at both ends of the supporting frame 11. The rotating sleeve 20 is fixedly connected to the middle of the upper end of the foot 13. The adjusting screw 12 is arranged in the middle of the upper end of the rotating sleeve 20, and the lower end of the adjusting screw 12 extends to the middle of the rotating sleeve 20 and is rotatably connected to the rotating sleeve 20. The upper end of the adjusting screw 12 extends into the supporting frame 11, and the adjusting screw 12 is threadedly connected to the supporting frame 11.

[0043] The outer end of the adjusting screw 12 is fixedly connected with the second nut 21 , and the adjusting screw 12 passes through the middle of the second nut 21 and is fixedly connected with the second nut 21 . The second nut 21 is located at the upper end of the rotating sleeve 20 and is rotatably connected with the rotating sleeve 20 .

[0044] The adjusting screw 12 is rotated by the second nut 21, and the adjusting screw 12 is matched with the thread of the support frame 11 to make the adjusting screw 12 enter or extend out of the support frame 11, thereby driving the feet 13 to respectively lift the heights of the two ends of the support frame 11, so that the device can remain horizontal on an uneven ground and fully contact the ground, ensuring that the first hoop body 6 and the second hoop body 8 can fit the column as completely as possible, ensuring the clamping effect of the clamping mechanism 1 on the column, and the adjusting screw 12 is rotatably connected to the rotating sleeve 20, so that when the adjusting screw 12 rotates, the friction between the ground and the feet 13 is used to prevent the feet 13 from rotating, thereby reducing the resistance of the adjusting screw 12 when rotating.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
