Description

Technical Field

[0001] This utility model relates to the field of ancient building restoration, and in particular to a protective device for wooden components of ancient buildings. Background Technology

[0002] The protection of wooden components in the restoration of ancient buildings refers to the comprehensive protection measures taken during the restoration of ancient buildings, which involve using techniques such as anti-corrosion, insect prevention, reinforcement, and surface treatment to protect the original wooden structural components in order to extend their service life and maintain the authenticity and integrity of the historical buildings.

[0003] Existing methods for protecting wooden components, such as reinforcing and protecting wooden columns in ancient buildings, often involve using scaffolding and fasteners for clamping and protection. However, such scaffolding protection is inefficient, time-consuming, and labor-intensive, affecting the overall restoration progress. Furthermore, the fixed scaffolding structure makes it difficult to quickly adjust to ancient building columns of different diameters and heights, resulting in insufficient versatility.

[0004] Therefore, a protective device for ancient building wooden components is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a protective device for ancient building wooden components, which has the advantages of being able to reinforce and protect ancient building columns of different specifications, having a simple overall structure, avoiding excessive construction, and reducing labor time.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A protective device for wooden components of ancient buildings, including a component protection structure;

[0008] The component protection structure includes a U-shaped fixing plate, with both ends of the fixing plate protruding, and positive and negative threaded rods are assembled between the fixing plates;

[0009] The positive and negative threaded rods are respectively equipped with sliding plates for engaging and sliding with the left and right threads on the outside. Each of the two sliding plates is equipped with a limit block on its inner side. Each of the two limit blocks is provided with a slot on one side and a locking block is embedded in the slot.

[0010] Both of the two card blocks are equipped with an arc-shaped plate on one side, and the two arc-shaped plates are arranged in opposite parallel directions. The inner sides of the two arc-shaped plates are provided with several sets of limiting components.

[0011] Furthermore, each of the limiting components includes several sets of compression springs arranged in a linear array, and one side of the several sets of compression springs is connected to a limiting plate.

[0012] Furthermore, several sets of limiting components are arranged in a ring-shaped interval on the same side.

[0013] Furthermore, two limiting rods are assembled between the fixing plates. The two limiting rods are arranged parallel to each other on both sides of the positive and negative threaded rods. Both limiting rods pass through the two sliding plates and are slidably connected to them.

[0014] Furthermore, one end of the positive and negative threaded rod passes through one side of the fixing plate and extends to be connected to a handle, and a ball bearing is fitted at the connection between the fixing plate and the positive and negative threaded rod.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. Through multiple structural elements and limiting components set within the component protection structure, in actual use, the combination of several sets of compression springs and limiting plates arranged in a linear array within each limiting component forms a flexible protection mechanism for the ancient architectural wooden components. This design can provide sufficient clamping force while effectively absorbing stress generated by external impacts, vibrations, and temperature changes through the elastic deformation of the compression springs, avoiding damage to precious ancient architectural wooden components that might be caused by rigid clamping. The ring-shaped spacing of the limiting plates within several sets of limiting components on the same side ensures all-round uniform protection of the wooden component surface, eliminating the risk of local stress concentration. The structure of two arc-shaped plates arranged in parallel opposite directions adapts to the circular cross-sectional characteristics of the ancient architectural wooden columns, achieving maximum protective coverage of the contact area.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0023] First embodiment;

[0024] Reference Figure 1-3 As shown, this is a preferred embodiment of the present invention of a protective device for ancient building wooden components, including a component protection structure 1;

[0025] The component protection structure 1 includes a U-shaped fixing plate 11 with both ends of the side protruding, and a positive and negative threaded rod 12 is assembled between the fixing plates 11.

[0026] The left and right threads of the positive and negative threaded rod 12 are respectively engaged and slidably provided with sliding plates 13. The inner side of each sliding plate 13 is equipped with a limit block 131. Each of the two limit blocks 131 has a slot on one side and a locking block 132 is embedded in the slot.

[0027] Both of the two card blocks 132 are equipped with an arc plate 14 on one side, and the two arc plates 14 are arranged in opposite parallel directions. The inner sides of the two arc plates 14 are surrounded by several sets of limiting components 15.

[0028] In this embodiment, the combination of several sets of compression springs 151 arranged in a linear array within the limiting component 15 and the limiting plates 152 forms a flexible protection mechanism for the wooden components of ancient buildings. This design can effectively absorb stress generated by external impacts, vibrations, and temperature changes through the elastic deformation of the compression springs 151 while providing sufficient clamping force, thus avoiding damage to the precious wooden components of ancient buildings that may be caused by rigid clamping. The arrangement of the limiting plates 152 in a ring at intervals within the several sets of limiting components 15 on the same side ensures all-round uniform protection of the surface of the wooden components and eliminates the risk of local stress concentration. The structure of the two arc-shaped plates 14 arranged in parallel opposite directions adapts to the circular cross-sectional characteristics of the wooden columns of ancient buildings, achieving maximum protective coverage of the contact area. The adjustable characteristics of the entire device enable it to adapt to wooden components of ancient buildings of different diameters, improving the versatility and practical value of the equipment, and providing a safe, reliable, and easy-to-operate professional protection tool for ancient building protection projects.

[0029] Second embodiment;

[0030] Reference Figure 1-3 As shown, each set of limiting components 15 includes several sets of compression springs 151 arranged in a linear array, and one side of the several sets of compression springs 151 is connected to a limiting plate 152.

[0031] In this embodiment, when the device clamps the wooden component, the externally applied pressure first acts on the limiting plate 152, and then is transmitted through the limiting plate 152 to multiple compression springs 151. The compression springs 151 undergo elastic deformation to absorb and buffer the pressure, while providing a continuous and stable reverse elastic support force for the limiting plate 152. This design can not only adapt to wooden components of different specifications, but also automatically adjust the contact pressure during the protection process, avoiding indentations or other mechanical damage to the surface of the ancient building's wooden components due to excessive pressure. At the same time, the elastic characteristics of the compression springs 151 can also absorb external vibrations and impacts, providing dynamic protection for the ancient building's wooden components.

[0032] Third embodiment;

[0033] Reference Figure 1-3 As shown, the 152s within several sets of limiting components 15 arranged on the same side are arranged in a ring with intervals.

[0034] In this embodiment, the annular spacing ensures that the limiting plate 152 forms a continuous and uniform protective cover inside the arc-shaped plate 14, avoiding blind spots or localized pressure concentration. Secondly, this spacing facilitates independent operation of each limiting plate 152. When there are slight unevenness or deformation on the surface of the wooden component, each limiting plate 152 can independently adjust its contact pressure and position via its connected compression spring 151, achieving adaptive fit. Furthermore, the annular spacing promotes air circulation and heat dissipation, preventing the formation of a sealed, humid environment between the wooden component and the device during long-term protection, thus avoiding potential mold or corrosion problems.

[0035] Fourth embodiment;

[0036] Reference Figure 1-3 As shown, two limiting rods 16 are assembled between the fixed plates 11. The two limiting rods 16 are arranged in parallel on both sides of the positive and negative threaded rods 12. Both limiting rods 16 pass through the two sliding plates 13 and are slidably connected to them.

[0037] In this embodiment, the two limiting rods 16 are arranged in parallel on both sides of the positive and negative threaded rods 12, forming a stable three-point support and guiding system. Both limiting rods 16 pass through the two slide plates 13 and maintain a sliding connection with them. This design ensures that the slide plates 13 maintain the correct direction and posture when moving under the drive of the positive and negative threaded rods 12. The presence of the limiting rods 16 effectively prevents the slide plates 13 from rotating, tilting, or shifting laterally during movement, ensuring that the slide plates 13 can only move linearly along a predetermined axial direction.

[0038] Fifth embodiment;

[0039] Reference Figure 1-3As shown, one end of the positive and negative threaded rod 12 passes through one side of the fixing plate 11 and extends to be connected to a handle 121. A ball bearing is fitted at the connection between the fixing plate 11 and the positive and negative threaded rod 12.

[0040] In this embodiment, the operator can easily grip the handle 121 to rotate it, driving the forward and reverse threaded rods 12 to rotate, thereby achieving precise control over the position of the slide plate 13. More importantly, ball bearings are installed at the key connection between the fixed plate 11 and the forward and reverse threaded rods 12. The application of this bearing system significantly reduces rotational friction resistance, allowing the operator to easily rotate the forward and reverse threaded rods 12 with less force, greatly improving the convenience and efficiency of operation.

[0041] Specific implementation process:

[0042] Step 1: The staff first moved the protective structure 1 as a whole to the vicinity of the wooden pillar of the ancient building to be protected, and determined the required opening width by observing the diameter of the pillar. The operator held the handle 121 and began to rotate the threaded rod 12. Due to the presence of ball bearings, the rotation process was very smooth and effortless. The left and right thread design of the threaded rod 12 allows the two sliding plates 13 to move synchronously in opposite directions. When rotated clockwise, the two sliding plates 13 move closer together, and when rotated counterclockwise, they move further apart. During this process, two limit rods 16 are set parallel to both sides of the threaded rod 12, passing through the two sliding plates 13 and maintaining a sliding connection with them, ensuring that the sliding plates 13 remain parallel during movement and avoiding tilting or jamming. Through continuous adjustment, the opening width of the U-shaped fixing plate 11 is made slightly larger than the diameter of the wooden pillar, preparing for subsequent precise positioning.

[0043] Step 2: Carefully place the protective device, with the adjusted opening width, onto the wooden column of the ancient building, ensuring the column is positioned between the two curved plates 14. At this point, precise clamping adjustment begins. Continue rotating the handle 121, causing the threaded rod 12 to slowly bring the sliding plate 13 closer together. The limiting blocks 131 on the inner sides of the two sliding plates 13 move accordingly, and through the engaging connection between the slot on one side and the locking block 132, the position of the curved plate 14 is precisely fixed. The two curved plates 14 are arranged parallel to each other, and their curved design perfectly conforms to the circular cross-section of the wooden column. During clamping, the operator needs to closely observe the contact between the curved plate 14 and the surface of the wooden column, ensuring uniform contact and no excessive local pressure. The cooperation mechanism between the locking block 132 and the limiting block 131 ensures the positional stability of the curved plate 14 during clamping, preventing lateral slippage or angular deviation, thus ensuring uniform coverage and protection of the wooden column.

[0044] Step 3: After the curved plate 14 makes initial contact with the surface of the ancient wooden column, the crucial protective function is achieved by several sets of limiting components 15 arranged around the inner side of the curved plate 14. Each set of limiting components 15 contains several sets of compression springs 151 arranged in a linear array. One side of these compression springs 151 is connected to a limiting plate 152, forming a complete elastic buffer protection system. As the clamping force increases, the limiting plates 152 in the several sets of limiting components 15 arranged on the same side, in a ring-shaped interval, sequentially come into contact with the surface of the wooden column. The compression springs 151 begin to compress and deform, providing continuous and uniform elastic pressure to the limiting plates 152. This pressure ensures a tight fit between the device and the wooden column, and also absorbs stress caused by external vibrations, impacts, and temperature changes through elastic deformation. After the clamping and fixing are completed, the entire protective device forms a stable protective shell. The limiting plates 152 directly contact the surface of the wooden column, providing all-round protection and effectively preventing mechanical damage, chemical corrosion, and environmental factors from damaging the ancient wooden column during construction.
