Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building restoration technology, specifically a top support mechanism for the maintenance of ancient buildings. Background Technology
[0002] Ancient brick archways, stone archways, and walls, having withstood the test of time and weather, possess significant historical value and are irreplaceable. Their rich historical value is a precious asset, and they also serve as a vehicle for the inheritance and continuation of cultural relics.
[0003] During the maintenance of ancient buildings, structural defects in brick and stone, brick and wood components, especially at the lower sill of brick and stone structures, can lead to weathering, powdering, efflorescence, and material deterioration due to dampness, efflorescence, and capillary action. This is particularly problematic when many components need replacement and are unevenly distributed. Different repair measures are required for different situations. Each repair method necessitates supporting and protecting individual or overall components during the repair process to ensure the stability and safety of the ancient building's structure. Current conventional support methods use steel pipes and timber framing to form a simple support structure. However, this method suffers from drawbacks during construction, including a small contact area at the support base, insufficient overturning resistance, instability due to its cantilevered nature, difficulty in height and level adjustment, and inability to quickly and effectively protect and support the original structure. Furthermore, the small contact area of the top support and the heavy local weight can lead to instability and potentially cause irreversible damage such as collapse, deformation, breakage, or fracture of the artifact. Therefore, improvements are needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 8As shown, this utility model provides a top support mechanism for the maintenance of ancient buildings, including a base plate 1. A threaded rod 2 is fixedly connected to the top of the base plate 1. A lifting bolt 3 is threadedly sleeved on the outer surface of the threaded rod 2. A sleeve 4 is movably sleeved on the outer surface of the threaded rod 2. The bottom of the sleeve 4 is movably connected to the top of the lifting bolt 3. A support plate 5 is fixedly sleeved on the outer surface of the sleeve 4. Channel steel 6 is movably installed on both the left and right sides inside the support plate 5. A support rod 7 is hinged to the right side of the top of the base plate 1. A retaining sleeve 8 is hinged to the top of the support rod 7. A vertical rod 9 is movably sleeved inside the retaining sleeve 8. A groove 10 is opened inside the bottom end of the vertical rod 9. The bottom of the vertical rod 9 is movably connected to the top of the base plate 1. An installation block 11 is fixedly installed on the top of the base plate 1. The interior of the installation block 11... A threaded rod 12 is connected to the threaded rod 12. A circular plate 13 is fixedly connected to the rear end of the threaded rod 12. A circular rod 14 located inside the groove 10 is fixedly connected to the rear end of the circular plate 13. A locking block 15 is movably connected to the rear end of the circular rod 14. When the operator needs to select bricks and stones for the ancient building, the base plate 1 is first placed on both sides of the wall. Then, the channel steel 6 is placed inside the support plate 5 through the wall. A shim is placed at the point where the channel steel 6 contacts the brick and stone wall to prevent damage to the brick and stone wall. At this time, by rotating the lifting bolt 3, the lifting bolt 3 rises along the outer surface of the threaded rod 2, thereby pushing the sleeve 4 to move upward, so that the support plate 5 can rise, thereby lifting the channel steel 6 upward, so that the channel steel 6 can play a supporting role for the brick and stone wall.
[0025] Among them, a level 16 is movably installed at the bottom of the inner surface of the channel steel 6, and a rotating block 17 is fixedly connected to the front end of the lead screw 12; by setting the level 16, the operator can judge whether the channel steel 6 is in a horizontal state, so that the channel steel 6 can better support the brick wall.
[0026] The outer surface of the sleeve 4 is fixedly fitted with a connecting plate 18, and the top of the connecting plate 18 is movably mounted with a first connecting block 19 and a second connecting block 20 respectively; the connecting plate 18 has a through hole, so that the operator can connect the two base plates 1 together through the through hole, thereby improving the overall anti-overturning ability of the base plate 1.
[0027] The first connecting block 19 and the second connecting block 20 are both movably fitted with a fastener 21. The bottom end of the fastener 21 passes through the connecting plate 18 and extends to the bottom of the connecting plate 18 and is movably fitted with the inner wall of the connecting plate 18. When the fastener 21 is located inside the first connecting block 19 and the connecting plate 18 or inside the second connecting block 20 and the connecting plate 18, it will fix the first connecting block 19 and the connecting plate 18 or the second connecting block 20 and the connecting plate 18.
[0028] The inner end of the first connecting block 19 is fixedly connected to the outer sleeve 22, and the inner end of the second connecting block 20 is fixedly connected to the inner sleeve 23. The inner surface of the outer sleeve 22 is movably sleeved with the outer surface of the inner sleeve 23. By inserting the inner sleeve 23 into the inside of the outer sleeve 22, the outer sleeve 22 and the inner sleeve 23 are connected together, and the two base plates 1 can be connected together as a whole.
[0029] The outer sleeve 22 has a first circular hole 24 inside, and the inner sleeve 23 has a second circular hole 25 inside; by aligning the first circular hole 24 with the second circular hole 25, the outer sleeve 22 and the inner sleeve 23 can be fixed together.
[0030] The outer sleeve 22 is movably fitted with a fixing bolt 26, and the outer surface of the fixing bolt 26 is movably fitted with the inner surface of the second round hole 25. The outer sleeve 22 and the inner sleeve 23 are fixed by inserting the fixing bolt 26 into the first round hole 24 and the second round hole 25.
[0031] Working principle and usage process of this utility model:
[0032] First, the operator places the base plate 1 on both sides of the brick wall that needs support. Then, the channel steel 6 is placed inside the support plate 5 through the wall, and a rubber pad is placed on the side of the channel steel 6 that contacts the brick wall to prevent damage. Next, by rotating the lifting bolt 3, the lifting bolt 3 rises along the outer surface of the threaded rod 2, thereby pushing the sleeve 4 upward. This allows the support plate 5 to lift the channel steel 6, thus enabling the channel steel 6 to provide support for the brick wall. Finally, the operator rotates the support rod 7 so that the vertical rod 9 contacts the wall and its bottom is flush with the wall. When the top of the base plate 1 is in contact, the screw 12 moves forward inside the mounting block 11 by rotating the rotating block 17. The locking block 15 is aligned with the slot 10 by rotating the locking block 15, so that the locking block 15 and the round rod 14 enter the inside of the slot 10. When the round plate 13 contacts the outer surface of the vertical rod 9, the locking block 15 will move to the outside of the slot 10. At this time, the locking block 15 is rotated to make the locking block 15 displaced from the slot 10, so that the bottom end of the vertical rod 9 can be fixed, so that the vertical rod 9 can support the brick wall and prevent the brick wall from tilting.
[0033] Then, by inserting the inner sleeve 23 into the inside of the outer sleeve 22, and placing the first connecting block 19 and the second connecting block 20 on the top of the two connecting plates 18 respectively, and by inserting the fastener 21 into the inside of the connecting plate 18, the outer sleeve 22 and the inner sleeve 23 are fixed respectively. Finally, the fixing bolt 26 is passed through the first round hole 24 and the second round hole 25, thereby completing the fixing between the outer sleeve 22 and the inner sleeve 23, and improving the overall overturning resistance of the base plate 1.
