Description

Technical Field

[0001] This utility model relates to the field of ancient building restoration technology, specifically to a seismic-resistant support structure for the restoration of ancient building brick and stone walls. Background Technology

[0002] Ancient buildings are a precious cultural heritage of the Chinese nation. Their brick and stone walls, having endured the vicissitudes of time, generally suffer from structural aging, cracks, and weathering, resulting in extremely poor seismic performance. Under earthquake action, these walls are prone to cracking, tilting, and even partial collapse, threatening not only the safety of the buildings themselves but also posing a significant risk to life and property. Traditional methods of reinforcing brick and stone walls, such as mortar grouting and carbon fiber cloth bonding, are limited. Mortar grouting only slightly enhances the overall integrity of the wall, offering limited seismic resistance. Furthermore, with carbon fiber cloth reinforcement, real-time observation and adjustment of the spacing during bonding are often inconvenient. Manual judgment increases the risk of operational errors, leading to inconsistent spacing and misaligned placement. The uneven distribution of carbon fiber cloth within a certain area on the wall surface also affects the protective effect and stability. Utility Model Content

[0003] The purpose of this utility model is to provide a seismic repair support structure for ancient building brick and stone walls. This support structure can ensure the uniformity of spacing and distribution of carbon fiber cloth during the pasting process on the wall surface, facilitate installation and disassembly, and further improve the pasting effect and efficiency of carbon fiber cloth, thereby further improving the seismic repair effect on ancient building brick and stone walls.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A seismic repair support structure for ancient building brick and stone walls includes several sets of carbon fiber cloths arranged at intervals along the horizontal and vertical directions of one side of the wall, two sets of first pressure plates and second pressure plates respectively arranged along the horizontal and vertical directions of one side of the wall for pressing the carbon fiber cloths, and an installation component for positioning the several sets of carbon fiber cloths. The two ends of the first pressure plates and second pressure plates are fixed by multiple sets of first pins and second pins respectively arranged on the corresponding wall surfaces. The installation component includes multiple sets of first positioning plates sleeved on the first pins and second pins located at the adjacent ends of the first pressure plates and second pressure plates on the corresponding wall surfaces, and two sets of second positioning plates slidably arranged along the two sets of first pressure plates or the two sets of second pressure plates. A first compression spring is sleeved on both the first pins and second pins. A first connecting rod and a second connecting rod are respectively arranged on the second positioning plate for connecting with the first pressure plates and the second pressure plates. A second compression spring is sleeved on the first connecting rod and an adjusting component is rotatably arranged on the corresponding rod body. Locking components are rotatably arranged on the first pins, the second pins, and the second connecting rods.

[0006] Preferably, the mounting assembly further includes a pressure seat that is slidably disposed along the first pressure plate or the second pressure plate.

[0007] Preferably, the bottom of the pressure seat is provided with multiple sets of rollers arranged at intervals.

[0008] Preferably, the first pressure plate and the second pressure plate are provided with multiple sets of third pins arranged at intervals on the corresponding wall surfaces, respectively, along the horizontal and vertical directions of the corresponding wall surfaces.

[0009] Compared with the prior art, this utility model has the following advantages and effects:

[0010] This utility model is a seismic repair support structure for ancient building brick and stone walls. Based on the traditional reinforcement method using carbon fiber cloth, the structural design and corresponding connection method of the first and second positioning plates in its installation components allow operators to easily observe and adjust the spacing of the carbon fiber cloth in real time during the pasting process. This ensures uniformity and distribution of the carbon fiber cloth on the wall surface, effectively reducing operational errors and minimizing inconsistent spacing and misalignment.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figure 1-7This embodiment relates to a seismic repair support structure for an ancient building brick and stone wall 100, including several sets of carbon fiber cloths arranged at intervals along the horizontal and vertical directions of one side wall of the wall 100, two sets of first pressure plates 1 and second pressure plates 2 respectively arranged along the horizontal and vertical directions of one side wall of the wall 100 for pressing the carbon fiber cloths, and an installation component 3 for positioning the several sets of carbon fiber cloths. The two ends of the first pressure plates 1 and second pressure plates 2 are respectively fixed by multiple sets of first pins 101 and second pins 102 arranged on the corresponding wall surface of the wall 100. The installation component 3 includes a first pin on the corresponding wall surface of the wall 100 located at the end adjacent to the first pressure plates 1 and second pressure plates 2. Multiple sets of first positioning plates 31 and two sets of second positioning plates 32 are sleeved on the first pin 101 and the second pin 102, and are slidably arranged along the two sets of first pressure plates 1 or the two sets of second pressure plates 2. A first compression spring 103 is sleeved on both the first pin 101 and the second pin 102. A first connecting rod 321 and a second connecting rod 322 are respectively provided on the second positioning plate 32 for connecting with the first pressure plate 1 and the second pressure plate 2. A second compression spring 323 is sleeved on the first connecting rod 321, and an adjusting member 324 is rotatably arranged on the corresponding rod body. A locking member 104 is rotatably arranged on the first pin 101, the second pin 102, and the second connecting rod 322.

[0022] Specifically in this embodiment, see Figure 1 and Figure 2 As shown, mortar can be pre-applied and smoothed on the corresponding side of the brick wall 100 to ensure the bonding stability of the carbon fiber cloth on the corresponding wall surface of the wall 100. Then, holes are drilled at corresponding positions on the wall surface of the wall 100 for the installation and fixing of multiple sets of first pins 101 and second pins 102. The first positioning plate 31 can be used for the installation of the first pins 101 and second pins 102 at corresponding positions through two sets of through holes 311. The length of the first positioning plate 31 can be set according to the specific bonding requirements of the initial bonding position of the carbon fiber cloth on the corresponding wall surface of the wall 100. Simultaneously, the length of the second positioning plate 32 can be set by measuring and evenly dividing the specific distance between adjacent first positioning plates 31 along the horizontal and vertical directions of the corresponding wall surface of the wall 100. See also... Figure 1-3The diagram illustrates the installation structure for longitudinal bonding of carbon fiber cloth. A first spring 103 is fitted onto the first pin 101 positioned above the first positioning plate 31. A first pressure plate 1, horizontally arranged at both ends of the wall 100, is installed by passing through first mounting holes 11 at both ends that are adapted to the size of the first pin 101. Simultaneously, during installation, the second positioning plate 32 of the first pressure plate 1 is fitted with a second spring 323 via a first connecting rod 321 on its body, which then passes through a first sliding groove 12 on the first pressure plate 1. Finally, locking elements 104 and adjusting elements 324, which are bolted together, are connected via threaded rods on the first pin 101 and first connecting rod 321. The rotating connection defines the position of the first pressure plate 1 and its second positioning plate 32, allowing for the application of carbon fiber cloth. Specifically, the first carbon fiber cloth is initially applied at a position flush with the side of the first positioning plate 31. The two longitudinally arranged first positioning plates 31 ensure the verticality of the first carbon fiber cloth application. Pulling the adjusting member 324 moves the first connecting rod 321 away from the wall 100, separating the second positioning plate 32 from the corresponding side of the wall 100. This allows the second positioning plate 32 to move along the first sliding groove 12 on the first pressure plate 1 towards the direction of the first applied carbon fiber cloth. Releasing the adjusting member 324 allows the second positioning plate 32 to adhere to the corresponding wall surface of the wall 100, simultaneously setting its position. Figure 1 For example, the first carbon fiber cloth can be attached to and kept flush with the side edge of the second positioning plate 32 away from the first carbon fiber cloth. Then, the next set of carbon fiber cloth is pasted along the other side edge of the second positioning plate 32 away from the first carbon fiber cloth. Thus, under the position limitation and position adjustment of the two sets of second positioning plates 32 on the two sets of first pressure plates 1 horizontally installed at the upper and lower ends of the wall 100, the longitudinally arranged carbon fiber cloths are pasted at equal intervals. After the longitudinally arranged carbon fiber cloths are pasted, refer to Figure 4 and Figure 5The installation method of the corresponding structure when pasting several sets of horizontally arranged carbon fiber cloths is shown. Referring to the installation method of the first pressure plate 1, the two sets of second pressure plates 2 with the appropriate size second mounting holes 21 at both ends of the second pressure plate 2 are used to install the two sets of second pressure plates 2 arranged longitudinally on the left and right sides of the wall 100. At the same time, during the installation of the second pressure plate 2, the second positioning plate 32 can be inserted into the second sliding groove 22 opened on the second pressure plate 2 through the first connecting rod 321 set on its plate body. Then, the position is limited by the rotation of the adjusting member 324. Specifically, the first horizontally arranged carbon fiber cloth can be flush with the corresponding side of the first positioning plate 31 when pasting. The two sets of first positioning plates 31 arranged horizontally can ensure the parallelism of the pasting of the first horizontally arranged carbon fiber cloth. Then, referring to the above operation process, the second positioning plate 32 slides along the second sliding groove 22 on the second pressure plate 2 to complete the entire pasting process of multiple sets of carbon fiber cloths arranged horizontally and vertically on the wall 100. Finally, when the carbon fiber cloth is pasted, refer to Figure 7 As shown, the first compression spring 103 fitted on the first positioning plate 31 and the second positioning plate 32, as well as the first pin 101 and the second pin 102 in the installation assembly 3, is disassembled. Then, the first pressure plate 1 and the second pressure plate 2 can be installed and locked by the locking member 104 pressing the edges of multiple sets of carbon fiber cloth on the first pin 101 and the second pin 102 along the horizontal and vertical directions of the corresponding wall surface of the wall 100, so as to complete the entire installation process of this kind of earthquake-resistant repair support structure for ancient building brick and stone wall 100. Based on the traditional reinforcement method using carbon fiber cloth, this support structure, through the structural design and corresponding connection method of the first positioning plate 31 and the second positioning plate 32 in its installation component 3, allows operators to easily observe and adjust the spacing of the carbon fiber cloth in real time during the pasting process. This ensures the uniformity and even distribution of the carbon fiber cloth on the wall surface, effectively reducing operational errors and minimizing inconsistent pasting spacing and misalignment. Furthermore, the ease of installation and disassembly, combined with the pressing action of the first pressure plate 1 and the second pressure plate 2, effectively reduces the occurrence of curling edges in the carbon fiber cloth, further improving the pasting effect and efficiency. This significantly enhances the seismic repair effect on the ancient building's brick and stone walls 100, while also exhibiting high structural detachability, flexibility, and applicability. Additionally, when this support structure... Figure 7 After installation, the first pin 101 and the second pin 102, which extend to a certain length on the corresponding wall surface of the wall 100, can be drilled to penetrate into the wall 100 during the early stage of installation, depending on the thickness of the first pressure plate 1 and the second pressure plate 2, or cut to a certain length according to the operation requirements. This effectively reduces the space occupied by this support structure and the unnecessary impact on the external environment, meeting different operating environments and operation requirements.

[0023] The installation assembly 3 also includes a pressure seat 33 that slides along the first pressure plate 1 or the second pressure plate 2. Specifically, when longitudinal carbon fiber cloth is pasted onto the wall surface corresponding to the wall 100, see [link to relevant documentation]. Figure 1 and Figure 2 The process of installing the second pressure plate 2, which is longitudinally arranged between two sets of second positioning plates 32, is carried out by the second connecting rod 322 provided on the second positioning plate 32, combined with the second compression spring 323 sleeved on its outer side and the locking member 104 rotatably provided on the rod body. At this time, the pressure seat 33 can be positioned and slide up and down along the second sliding groove 22 opened on the second pressure plate 2 through the adapter handle 331 provided on its upper seat body. Thus, after the longitudinally arranged carbon fiber cloth is initially pasted, it can be seen that... Figure 3 The process shown illustrates the bonding and pressing of the second pressure plate 2 and its upper pressure seat 33 onto the corresponding carbon fiber cloth via the second positioning plate 32 and the first sliding groove 12 on the first pressure plate 1. The operator can then press the pressure seat 33 onto the carbon fiber cloth using the handle 331 and slide it up and down along the second sliding groove 22 on the second pressure plate 2 to achieve stable bonding of the carbon fiber cloth to the corresponding wall surface of the wall 100. When bonding the carbon fiber cloth horizontally to the corresponding wall surface of the wall 100, please refer to... Figure 4 and Figure 5 The first pressure plate 1 shown can be disassembled from the first pin 101 and positioned on the second positioning plate 32, which is located in the second groove 22 of the second pressure plate 2. Through the first connecting rod 321 combined with the second compression spring 323 sleeved on its outer side and the adjusting member 324 rotatably set on the rod body, the first pressure plate 1 is installed in the second groove 22 of the second pressure plate 2 during the insertion process. At this time, the second connecting rod 322 located on the second positioning plate 32 can be inserted into the first groove 12 opened on the first pressure plate 1. At the same time, the pressure seat 33 can be positioned and slid left and right in the first groove 12 of the first pressure plate 1 through the handle 331 set on it. Thus, the horizontally arranged carbon fiber cloth can be stably bonded in combination with the above operation process. The addition of the pressure base 33 further enhances the functional versatility and flexibility of the installation component 3, while also improving the ease of operation and adhesion stability during the bonding process of the carbon fiber cloth to the corresponding wall surface of the wall 100. In addition, the width of the pressure base 33 should be slightly larger than the width of the carbon fiber cloth to ensure the comprehensiveness and ease of operation during the covering and pressing process of the carbon fiber cloth. Furthermore, the structural design of the first pressure plate 1 and the second pressure plate 2 facilitates disassembly and assembly while offering high versatility and flexibility in structural conversion during disassembly and assembly, meeting different operational needs and improving applicability and practicality.

[0024] The bottom of the pressure seat 33 is rotatably equipped with multiple sets of rollers 332 arranged at intervals, from... Figure 3 or Figure 6 As can be seen, the addition of multiple sets of rollers 332 at the bottom of the pressure seat 33 not only ensures the stability of pressing the carbon fiber cloth, but also improves the speed at which the operator can move and press the carbon fiber cloth by rotating the rollers 332 during the movement of the pressure seat 33. At the same time, it can also effectively reduce the unnecessary wear on the surface of the carbon fiber cloth and improve the performance of the pressure seat 33.

[0025] The first pressure plate 1 and the second pressure plate 2 are provided with multiple sets of third pins 105 spaced apart on the corresponding wall surfaces of the wall 100, arranged in both horizontal and vertical directions. Specifically, from... Figure 8 As can be seen, the first pressure plate 1 and the second pressure plate 2 can be installed on the corresponding wall surface of the wall 100 according to the operation requirements. Multiple sets of third pins 105, which are drilled and fixed in the corresponding wall surface of the wall 100, are arranged at intervals in the first sliding groove 12 and the second sliding groove 22, respectively. This can further improve the stability of the first pressure plate 1 and the second pressure plate 2 on the corresponding wall surface of the wall 100, as well as the pressing effect on the carbon fiber cloth and the bonding stability of the carbon fiber cloth. This further improves the overall structural strength and function of this earthquake-resistant repair support structure for the ancient building brick and stone wall 100, and enhances the earthquake-resistant repair effect of the support structure on the ancient building brick and stone wall 100, thus meeting different operation requirements.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
