Description

TECHNICAL FIELD

[0001] The present application relates to the field of ancient building repair device, especially to a support structure for ancient building repair. BACKGROUND

[0002] In the ancient building protection and repair project, the building body mainly composed of wood, stone and brick has high historical and cultural value. Among them, the stone has relatively good strength and durability, and the brick is convenient to replace. However, the wooden column as the main load-bearing component is extremely easy to be seriously damaged due to factors such as long time, environmental erosion, etc. such as decay, insect damage, cracking, and skewing. In order to ensure the safe performance of the repair work, a support structure is usually used to form a stable and reliable support on the outer side of the damaged or reinforced wooden component (especially the wooden column) to maintain its structural stability and facilitate subsequent repair operations such as reinforcement, replacement or surface treatment.

[0003] At present, the support for the ancient building wooden column mostly adopts scaffolding or customized support frame. However, the traditional support structure has significant defects. First, its height is mostly fixed or has limited adjustment range, which is difficult to accurately adapt to the actual requirement of great height difference of the wooden column in different ancient buildings. When the height of the support structure is insufficient, it cannot provide effective support. When the height is too high, it needs to be padded or the customized equipment has to be purchased, which not only greatly increases the construction difficulty and time cost, but also significantly increases the project expenditure. Second, the traditional support structure often relies on bolt fastening or welding when installing and adjusting the height, which is complex, time-consuming and low in efficiency, and cannot meet the requirement of efficient operation in the ancient building repair site. More importantly, the traditional support lacks effective adaptability to the surface form and stress state of the wooden column. The support point position is fixed and rigidly contacted, which is difficult to finely adjust according to the actual inclination angle and irregular surface form (such as carving and decay) of the wooden column, and is extremely easy to cause uneven distribution of support force and generate excessive concentrated stress in the local area of the wooden column, which constitutes a serious risk of secondary damage to the fragile and damaged precious ancient building wooden column.

[0004] Therefore, how to develop a support structure for ancient building repair, which can quickly adjust the support height according to the actual height requirement of the ancient building wooden column, and avoid secondary damage to the ancient building wooden column due to improper support, has become a technical problem to be solved by the person skilled in the art.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: 1) This invention achieves precise and rapid adjustment of the overall height of the support structure through modular design of unit components and matching inclined guide and spring self-locking plug-in components. Construction personnel only need to increase or decrease the number of unit components according to the actual height requirements of the ancient building's wooden columns and stack and assemble them using the automatic locking function of the plug-in components to accurately match support scenarios of different heights. This design completely changes the shortcomings of traditional fixed-height support frames, such as poor adaptability and the need for customization or secondary procurement, greatly improves the versatility and site adaptability of the device, effectively reduces the additional cost input caused by equipment height mismatch, and at the same time, the plug-in process does not require tools, which significantly improves the efficiency of on-site installation and disassembly. 2) The support structure adopts a transverse connecting beam system that can slide flexibly along the height of the column and be quickly positioned by a limiting component that can be unlocked by pressing / locked with a one-button press. Combined with adjustable wooden column supports, it can be precisely positioned in key stress areas according to the actual condition of the wooden column. The wooden column supports have telescopic adjustment function and hinged self-adaptive support seats. The working end is covered with an elastic layer that can fit tightly and flexibly against the surface of the wooden column, especially suitable for irregular shapes such as carvings and grooves. This multi-point, flexible and position-adjustable self-adaptive support method effectively disperses the load borne by the wooden column and greatly reduces the risk of local stress concentration caused by improper support point position or rigid contact, thereby avoiding secondary pressure damage or scratches to the already damaged precious ancient building wooden column body. 3) Based on height-adjustable and flexible support, the support structure strengthens the bending stiffness of key nodes through triangular reinforcing plates at the connection between the base and the column. It is also equipped with an adjustable length and angle diagonal support rod system. The two ends of the diagonal brace are hinged to the base and the column at different heights to form a stable triangular support system, which significantly enhances the overall rigidity and anti-tilting ability of the support device. Even in complex construction environments or when supporting tall and tilted wooden columns, it can provide reliable and stable support force, effectively ensuring the safety of the ancient building repair operation and the reliability of the structure itself.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figures 1-14 As shown, a support structure for the repair of ancient buildings includes a base 1, column assemblies 2, transverse connecting beams 3, wooden column supports 4, and diagonal support rods 5. Two column assemblies 2 are vertically inserted into the top of the base 1, arranged side-by-side. Each column assembly 2 includes a left column assembly 21 and a right column assembly 22. Both the left and right column assemblies 21 and 22 are assembled from multiple end-to-end unit components 23. Multiple transverse connecting beams 3 are spaced apart along the height direction of the left and right column assemblies 21 and 22, and both ends of each transverse connecting beam 3 are slidable. The wooden column support members 4 are sleeved on the opposite surfaces of the left column assembly 21 and the right column assembly 22 and are fixedly connected between the left column assembly 21 and the right column assembly 22 by the first limiting component 6. The multiple wooden column support members 4 are spaced apart on the top of the transverse connecting beam 3 along the height direction, and the working end of the wooden column support member 4 is used to abut against the outer side of the wooden component. The multiple inclined support rods 5 are respectively located on the left and right sides of the base 1. One end of the inclined support rod 5 is hinged to the base 1, and the other end of the inclined support rod 5 is hinged to the column assembly 2 located on the same side.

[0022] Specifically, this invention achieves adjustable support structure height through modularly designed unit components 23. Each unit component 23 can be quickly assembled and disassembled via plug-in components 7. During construction, the overall height of the support structure can be precisely adjusted by increasing or decreasing the number of unit components 23 according to the actual height requirements of the ancient building's wooden pillars. This can adapt to the support needs of ancient building wooden pillars of different heights. Compared with traditional fixed-height support frames, this design significantly improves the versatility and site adaptability of the device, effectively reducing the secondary procurement costs caused by mismatched support equipment heights in ancient building restoration projects.

[0023] Specifically, the unit component 23 is connected to the top of the base 1 by plugging in the connector 7, and multiple unit components 23 are connected to each other by plugging in the connector 7. The plug-in assembly 7 includes a plug connector 71, a plug interface 72, a first slider 73, a first guide rod 74, a first spring 75, a first plug block 76, a first mounting plate 77, and a first locking nut 78. Two first guide rods 74 are fixedly connected side-by-side to the outer cavity wall of the plug interface 72 along a direction perpendicular to the axis of the plug interface 72, and the outer ends of the first guide rods 74 are threaded. The first slider 73 and the first spring 75 are both slidably sleeved on the first guide rods 74. The first mounting plate 77 is sleeved on the threaded ends of the first guide rods 74 and connected via the first... A locking nut 78 is locked to the first guide rod 74. The two ends of the first spring 75 abut against the opposite surfaces of the first slider 73 and the first mounting plate 77, respectively. One end of the first plug block 76 is fixedly connected to the first slider 73. The other end of the first plug block 76 passes through the cavity wall of the plug interface 72 and extends inward. The first plug block 76 slides back and forth with the first slider 73. The plug connector 71 is used to be inserted into the plug interface 72. The plug connector 71 has a first limiting hole 79 that matches the first plug block 76.

[0024] Specifically, the top of the working end of the first plug block 76 is provided with a first guide slope, and the bottom end of the plug connector 71 is provided with a second guide slope that matches the first guide slope.

[0025] Specifically, the plug-in assembly 7 used in this invention achieves rapid connection between unit component 23 and first support rod 12 and unit component 23 through inclined guide and spring self-locking mechanism. When the operator aligns the plug 71 with the plug interface 72, the first guide inclined surface at the top of the first plug block 76 interacts with the second guide inclined surface at the bottom of the plug, causing the first plug block 76 to retract axially along the first guide rod 74 and compress the first spring 75. After the plug 71 is fully inserted, the restoring force of the first spring 75 pushes the first plug block 76 to accurately engage with the first limiting hole 79, completing the self-locking fixation. The entire process does not require auxiliary tools, facilitating rapid assembly operations for the operator.

[0026] Specifically, the detachable structure of the first mounting plate 77 is fixed by the first locking nut 78, which not only ensures the reliability of the connection during construction, but also facilitates the later maintenance and replacement of vulnerable parts such as the first spring 75.

[0027] Specifically, the base 1 includes a base body 11, a first support rod 12, and a triangular support plate 13. The base body 11 is configured as a square frame structure. Two first support rods 12 are arranged vertically side by side on one side of the short side of the base body 11, and the top of the first support rod 12 is provided with the insertion interface 72. The triangular support plate 13 is fixedly connected to the angle position between the base body 11 and the first support rod 12.

[0028] Specifically, the triangular support plate 13 is rigidly connected to the axial angle region between the base body 11 and the first support rod 12, forming a stable right-angled triangular force transmission structure, which effectively improves the bending stiffness of the connection node between the base body 11 and the first support rod 12.

[0029] Specifically, the unit component 23 includes a second support rod 231 and a first guide groove 232. The top of the second support rod 231 is provided with the insertion interface 72, and the bottom of the second support rod 231 is fixedly connected with the insertion connector 71. Two first guide grooves 232 extend along the axial direction of the second support rod 231 and are symmetrically opened on two adjacent side walls in the circumferential direction.

[0030] Specifically, the transverse connecting beam 3 includes a connecting plate 31 and an L-shaped slider 32. The four L-shaped sliders 32 are respectively arranged on the left and right sides of the connecting plate 31, with two on each side. The vertical bending portions of the two L-shaped sliders 32 on the same side are arranged opposite each other. The vertical bending portions are slidably connected to the first guide groove 232. The inner side of the horizontal bending portion of the L-shaped slider 32 is in contact with the side wall of the second support rod 231.

[0031] Specifically, the setting of the transverse connecting beam 3 not only significantly enhances the overall structural stability between the left column assembly 21 and the right column assembly 22, but more importantly, in conjunction with the L-shaped slider 32, the first guide groove 232 and the first limiting component 6, it enables the flexible installation and limiting fixation of multiple transverse connecting beams 3 at different height positions of the column assembly 2. Users can adjust the required number of transverse connecting beams 3 according to the actual number of assembly unit components 23 to ensure that the entire support device remains stable at any height. This height-adjustable support structure design allows the wooden column support component 4 to be precisely set in the key support area according to the actual height requirements of the ancient building's wooden column. It is generally recommended to arrange the wooden column support component 4 in the ranges of 0%-30%, 40%-60%, and 70%-90% of the wooden column height to form multi-point support, thereby effectively dispersing the load borne by the wooden column and avoiding excessive local stress due to improper support point positions, thus preventing damage to the wooden column body of the ancient building. At the same time, users can freely decide the number of wooden column support pieces 4 according to the specific height characteristics and support requirements of the wooden column, and choose to fix them to the most suitable horizontal connecting beam 3 position, further improving the adaptability and effectiveness of the support.

[0032] Specifically, the first limiting component 6 includes a first housing 61, a first partition plate 62, a second partition plate 63, a first insertion post 64, a second spring 65, a lever 66, and a snap-fit ​​plate assembly 67. Two first housings 61 are symmetrically disposed at the bottom ends of the connecting plate 31, and the interior of each first housing 61 is a cavity structure. The first partition plate 62 and the second partition plate 63 are spaced apart within the cavity of the first housing 61, and together with the upper and lower cavity walls of the first housing 61, form the mounting cavity of the snap-fit ​​plate assembly 67. A first clearance hole is provided on the side wall of the mounting cavity. The snap-fit ​​plate assembly 67 is slidably embedded in the mounting cavity, and its pressing end extends outward through the first clearance hole. A second limiting hole 68 is provided at the center of the first partition plate 62 and the second partition plate 63. A third limiting hole is provided on the snap-fit ​​plate assembly 67. Hole 671, the first plug-in post 64 is slidably embedded in the inner cavity of the first housing 61, and the working end of the first plug-in post 64 extends outward after passing through the second limiting hole 68, the third limiting hole 671 and the cavity wall of the first housing 61 in sequence. The second support rod 231 has a plurality of fourth limiting holes 233 that match the first plug-in post 64 at equal intervals along its length direction. The first plug-in post 64 is provided with a limiting boss 69, which is used to abut against the first partition plate 62. The two levers 66 are fixedly connected to both sides of the first plug-in post 64. The first housing 61 is provided with a second clearance hole for the levers 66 to slide. The second spring 65 is sleeved and connected to the first plug-in post 64, and the two ends of the second spring 65 abut against the inner cavity wall of the first housing 61 and the levers 66 respectively.

[0033] Specifically, the snap-fit ​​plate assembly 67 includes a snap-fit ​​plate body 672, a second guide rod 673, and a third spring 674. The snap-fit ​​plate body 672 is slidably embedded in the mounting cavity. The third limiting hole 671 is opened at the center of the snap-fit ​​plate body 672, and its diameter matches the diameter of the first insertion post 64. A limiting groove 675 is opened on the side of the first insertion post 64 near its working end. The groove width of the limiting groove 675 matches the diameter of the third limiting hole 671. One end of the snap-fit ​​plate body 672 extends outward through the first clearance hole. A plurality of second guide rods 673 are evenly spaced at the other end of the snap-fit ​​plate body 672, and the second guide rods 673 are slidably connected to the cavity wall of the mounting cavity. The third spring 674 is sleeved on the second guide rods 673, and its two ends abut against the snap-fit ​​plate body 672 and the cavity wall of the mounting cavity, respectively.

[0034] Specifically, in the initial state, the limiting groove 675 on the first insertion post 64 is engaged with the third limiting hole 671 on the snap-fit ​​plate body 672. At this time, the first insertion post 64 is in a retracted state. When the user slides the connecting plate 31 along the second support rod 231 to the preset height position, presses the operating end of the snap-fit ​​plate body 672, forcing the snap-fit ​​plate body 672 to overcome the elastic force of the third spring 674 and retract axially into the mounting cavity along the second guide rod 673. The movement of the snap-fit ​​plate body 672 releases the snap-fit ​​constraint of the third limiting hole 671 on the limiting groove 675 of the first insertion post 64. Subsequently, under the elastic force of the second spring 65, the first insertion post 64 automatically pops out, and its working end is accurately inserted into the corresponding fourth limiting hole 233 on the second support rod 231, thereby completing the locking of the connecting plate 31 at this height. Specifically, when the connecting plate 31 needs to be disassembled after construction is completed, the user pulls the lever 66 outward. The lever 66 drives the first plug post 64 to move inward against the elastic force of the second spring 65. When the first plug post 64 moves to the point where the limiting groove 675 on it is aligned with the third limiting hole 671 on the snap plate body 672, the snap plate body 672 automatically pops outward under the reset action of the third spring 674, and its third limiting hole 671 is re-engaged into the limiting groove 675. At this time, the working end of the first plug post 64 is disengaged from the fourth limiting hole 233 and locked in the retracted position by the snap plate body 672, so that the user can freely slide or disassemble the connecting plate 31.

[0035] Specifically, the wooden column support 4 includes a second housing 41, a first threaded rod 42, a crank handle 43, a second slider 44, a first connecting rod 45, a second connecting rod 46, a support base 47, and an elastic layer 48. The second housing 41 is fixedly connected to the top of the connecting plate 31, and the interior of the second housing 41 is set as a cavity structure. One end of the first threaded rod 42 is rotatably connected to the inner cavity wall of the second housing 41, and the other end of the first threaded rod 42 passes through the cavity wall of the second housing 41 and is fixedly connected to the crank handle 43. Two second sliders 44 are symmetrically sleeved on the first threaded rod 42 and are threadedly engaged with the first threaded rod 42. The second connecting rod 46 is slidably connected to the cavity wall of the second housing 41. The two ends of the first connecting rod 45 are respectively hinged to the second slider 44 and the second connecting rod 46. The extended end of the second connecting rod 46 is hinged to the support base 47. The working end of the support base 47 is attached with an elastic layer 48.

[0036] Specifically, the support base 47 can extend and retract under the drive of the second connecting rod 46. When the ancient building wooden column that needs to be supported is tilted, the operator can adjust the extension length of the support base 47 to ensure that the elastic layer 48 attached to its working end can be tightly and reliably attached to the surface of the wooden column, providing effective support. At the same time, the hinged connection design between the support base 47 and the second connecting rod 46 gives the support base the ability to adapt its angle, allowing it to adjust its posture accordingly with the change of the tilt angle of the wooden column, ensuring that the maximum force-bearing surface of the support base 47 always maintains good contact with the surface of the wooden column, optimizing the transmission of force. Specifically, the elastic layer 48 provided at the working end of the support base 47 serves two purposes: firstly, it acts as a buffer, significantly reducing the risk of pressure damage or scratches to the surface of the precious ancient wooden column caused by the support operation; secondly, its excellent elastic deformation ability can fully adapt to the carved patterns, natural irregular shapes, or other non-flat structures on the surface of the wooden column, increasing the effective contact area by filling the contact gaps, thereby achieving more stable and uniform support for the wooden component. The elastic layer 48 can be made of materials with good elasticity and durability, such as polyurethane or rubber, to meet the above-mentioned protection and adaptation functional requirements.

[0037] Specifically, the inclined support rod 5 includes an outer rod 51, an inner rod 52, and a second limiting component 53. The inner rod 52 is telescopically embedded inside the outer rod 51. The fixed end of the outer rod 51 is hinged to the base body 11. The fixed end of the inner rod 52 is detachably hinged to the hinge seat on the second support rod 231 via a positioning pin. The second limiting component 53 is installed on the side of the outer rod 51 near the inner rod 52 and is used for limiting the insertion of the inner rod 52.

[0038] Specifically, the inner rod 52 has multiple sets of fifth limiting holes that cooperate with the second limiting component 53.

[0039] Specifically, the second limiting component 53 in this invention is an existing structure, referring to the locking mechanism in the patent (patent number: CN212773638U), which will not be described in detail here.

[0040] The usage process of this invention is as follows: First, based on the actual height requirements of the wooden pillars of the ancient building to be supported, determine the required number of unit components 23. Securely place the base body 11 in the predetermined position. Then, select the appropriate number of unit components 23 for assembly. During assembly, align the connector 71 at the bottom of the lowest unit component 23 with the insertion interface 72 on the first support rod 12 at the top of the base 1. During insertion, the second guide slope at the bottom of the connector 71 interacts with the first guide slope at the top of the first insertion block 76 inside the insertion interface 72, forcing the first insertion block 76 to drive the first slider 73 along the first guide rod 74. The first spring 75 is compressed and axially retracted. When the connector 71 is fully inserted, the restoring force of the first spring 75 pushes the first connector block 76 to precisely engage in the first limiting hole 79 on the connector 71, achieving self-locking and completing the connection between the unit component 23 and the base 1. The subsequent unit components 23 are connected end to end using the same connector assembly 7, that is, the connector 71 of the upper unit component 23 is inserted into the connector 72 at the top of the lower unit component 23, and they are stacked and assembled upwards in sequence until the required height is reached, forming the complete left column assembly 21 and right column assembly 22. Secondly, based on the support height and structural stability requirements, determine the required number of transverse connecting beams 3 and their installation height on the column assembly 2. Align the L-shaped sliders 32 on both sides of the transverse connecting beam 3 with the first guide grooves 232 of the corresponding second support rods 231 on the left and right column assemblies 21 and 22, respectively. Slide the connecting plate 31 along the grooves to the preset height position. After reaching the preset height, press the operating end of the snap-fit ​​plate body 672 on the first housing 61 of the first limiting assembly 6, causing the snap-fit ​​plate body 672 to move into the installation cavity against the elastic force of the third spring 674, releasing the snap-fit ​​constraint of its third limiting hole 671 on the upper limiting groove 675 of the first insertion post 64. At this time, under the action of the second spring 65, the first insertion post 64 automatically pops out, and its working end is accurately inserted into the corresponding fourth limiting hole 233 on the second support rod 231, thereby firmly locking the transverse connecting beam 3 at this height position. Repeat this operation to install the required number of transverse connecting beams 3 at different heights of the column assembly 2. Next, connect the fixed end of the outer rod 51 of the inclined support rod 5 to the hinge points on both sides of the short side of the base body 11. According to the support angle and stability requirements, pull out the inner rod 52 to the required length. Use the second limiting component 53 to lock the fifth limiting hole on the inner rod 52 to the outer rod 51 to realize the length adjustment of the inclined support rod 5. Then, the fixed end of the inner rod 52 is hinged and fixed to the hinge seat of the corresponding height on the column assembly 2 through the positioning pin. The installation method of the inclined support rods 5 on the left and right sides is the same. After installation, a stable triangular support system is formed, which enhances the anti-tilting ability of the overall structure. Then, the wooden column support 4 is fixedly installed on the connecting plate 31 on top of the positioned transverse connecting beam 3. Based on the diameter, inclination, and surface shape of the wooden column to be supported, the crank handle 43 is turned to drive the first threaded rod 42 to rotate. The rotation of the first threaded rod 42 causes the two second sliders 44, which are threadedly engaged with it, to move towards or away from each other along the axial direction of the threaded rod. This, in turn, pushes the second connecting rod 46 to extend or retract via the first connecting rod 45. The extension or retraction of the second connecting rod 46 causes the support seat 47, which is hinged to it, to extend or retract, and its working end to adhere to the support. The elastic layer 48 (such as polyurethane or rubber) is tightly and reliably attached to the surface of the wooden column. The hinged design of the support base 47 and the second connecting rod 46 allows it to adapt to the tilt angle of the wooden column, ensuring good contact between the maximum stress surface of the elastic layer 48 and the surface of the wooden column. Depending on the height of the wooden column and the support requirements, multiple wooden column supports 4 can be installed on the transverse connecting beams 3 at different heights. It is generally recommended to arrange them in the range of 0%-30%, 40%-60%, and 70%-90% of the height of the wooden column to distribute the load and avoid excessive local stress that could damage the wooden column. Finally, after all components are installed and adjusted, an overall structural inspection is carried out to confirm that each unit component 23 is firmly inserted, the transverse connecting beam 3 is reliably limited by the first limiting component 6, the diagonal support rod 5 is properly tensioned, and the support seat 47 of the wooden column support 4 is tightly attached to the wooden column and the elastic layer 48 is undamaged. At this point, the support structure can provide stable, uniform and adjustable support force for the wooden column of the ancient building. After the maintenance work is completed, the disassembly process is carried out in reverse order.
