Description

Technical Field

[0001] The present invention relates to the field of ancient pagoda reinforcement devices, and in particular to a detachable ancient pagoda reinforcement device and a reinforcement method. Background Art

[0002] Ancient pagodas, with their graceful forms and unique structures, not only possess significant historical and cultural value but are also the focus of numerous scientific and technological researchers. However, due to natural disasters and human damage, most ancient pagodas have collapsed and disappeared. Brick and stone pagodas, with their inherent fire resistance and strong resistance to environmental fluctuations, are the most numerous surviving ancient pagodas. However, their large size and weight expose them to long-term high-pressure stresses, leading to internal damage such as cracks in the tower and falling eaves. This damage compromises the structural integrity, reduces bearing capacity, increases deformation, and can even lead to collapse, seriously threatening the safety of the ancient pagodas.

[0003] Currently, the restoration and conservation of ancient pagoda structures is primarily based on the principles of "repairing the old as it was," "minimum intervention," and "resilience to disasters." Based on the mechanisms and patterns of pagoda damage in different situations, corresponding reinforcement and conservation measures should be proposed based on these principles, with a focus on emergency conservation efforts for endangered pagodas. Steel reinforcement has become the mainstream method for tower reinforcement. The greatest advantage of steel as a reinforcement is its high reversibility. If removal becomes necessary for other reasons, it is relatively easy. Furthermore, while improving structural performance, it does not alter the original state of the building. Therefore, the use of steel reinforcement closely adheres to the principles of ancient pagoda restoration. This protective mechanism ensures that ancient pagodas will endure for generations to come, allowing future generations to appreciate the beauty of historical architecture.

[0004] At present, the reinforcement method of ancient tower structure is usually to use the cross-tension anchor rod to lock the inner and outer steel belt hoops and vertical through steel bars, such as Figure 1 As shown, the specific implementation is as follows: ① Two steel belts are set inside the tower body and on the outer tower surface for hooping. The steel belt adopts 8mm thick steel plate with a width of 10cm, and the adjacent steel belts are welded and connected with 8mm thick angle steel. Before construction, Φ40mm holes are reserved for the outer hoop steel belt and the inner steel belt of the tower body. Φ25mm through-tension anchor rods are set in the holes to lock the inner and outer steel belt hoops to form a whole. ② 4 vertical through steel bars are set on each side. First, grooves are cut at the positions of the vertical through steel bars of the tower body, and every 2 Φ28 steel bars are placed side by side in the vertical grooves. The bottom of the vertical steel bars are connected tightly to the original foundation using the embedded steel bar technology.

[0005] The above reinforcement methods are complex in structure, mostly welding, and the reinforcement method is irreversible, which makes it inconvenient for workers to disassemble and install. That is, it is not detachable and cannot be reinforced twice. At the same time, most of the existing reinforcement methods cause large disturbances to the tower body. For example, grooves need to be carved on the outside of the tower body, thereby destroying the original shape of the tower body, and stress concentration is prone to irreversible damage to the grooved part of the tower body. Summary of the Invention

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are intended only to explain the relevant content and are not intended to limit the present invention. It should also be noted that, for ease of description, only portions relevant to the present invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1 、 2As shown in Figures 3 and 4, the present invention provides a detachable ancient tower reinforcement device, including an external angle steel 1 and an internal angle steel 2. The external angle steel 1 is respectively installed on the edges of the outer wall of the ancient tower, and the internal angle steel 2 is respectively installed in the edges and corners of the inner wall of the ancient tower. When the external angle steel 1 and the internal angle steel 2 are installed, the inner wall of the external angle steel 1 fits with the outer wall of the ancient tower, and the outer wall of the internal angle steel 2 fits with the inner wall of the ancient tower. Since the edges on the outer wall of the ancient tower correspond to the edges and corners on the inner wall of the ancient tower, after the internal angle steel 2 and the external angle steel 1 are installed, the corresponding edges and corners on the ancient tower and the internal angle steel 2 and the external angle steel 1 installed on the edges also correspond to each other.

[0030] A steel plate 3 is also connected between two adjacent internal angle steels 2 installed in the corners of the inner wall of the ancient tower. After the steel plates 3 are installed, the steel plates 3 extend horizontally. Generally, the interior of the ancient tower is a cavity structure, and the outer wall and the inner wall of the ancient tower are of the same shape, that is, the number of faces of the outer wall of the ancient tower is the same as the number of faces of the inner wall of the ancient tower. The internal angle steel 2 and the external angle steel 1 located on the same side of the wall of the ancient tower are the corresponding internal angle steels 2 and external angle steels 1. A tension anchor rod 4 is connected between the same side flanges of the internal angle steel 2 and the external angle steel 1. Since the two ends of the tension anchor rod 4 are fixed to the internal angle steel 2 and the external angle steel 1 respectively, the tension anchor rod 4 will penetrate the wall of the ancient tower when connecting the internal angle steel 2 and the external angle steel 1.

[0031] In the present invention, since the end of the steel plate 3 is directly connected to the flange of the internal angle steel 2 when it is connected to the internal angle steel 2, and the end of the tension anchor rod 4 is also directly connected to the flange of the internal angle steel 2 when it is connected to the internal angle steel 2, therefore, in order to facilitate the installation and disassembly of the present invention, a through hole can be directly opened at the end of the steel plate 3, and when the tension anchor rod 4 is installed, the inner end of the tension anchor rod 4 simultaneously passes through the through hole on the internal angle steel 2 and the through hole at the end of the steel plate 3, so that the inner end of the tension anchor rod 4 can fix the end of the steel plate 3 while being fixed to the internal angle steel 2, so that there is no need to use welding or bolts or the like for additional fixation between the steel plate 3 and the internal angle steel 2, making the installation and disassembly of the present invention more convenient.

[0032] In order to ensure the tension of the tension anchor rod 4, Figure 2 、 3 As shown in Figure 4, a tensioning structure 7 is also installed on the flange of the internal angle steel 2. When the tension anchor rod 4 is fixed to the external angle steel 1, the tensioning structure 7 can tighten the tension anchor rod 4. After the tension anchor rod 4 and the tensioning structure 7 are locked, the internal angle steel 2 and the external angle steel 1 are tightened by the tension anchor rod 4, and the tensioning force is applied to the wall of the ancient tower, thereby improving the reinforcement effect of the ancient tower.

[0033] like Figure 6 、 7As shown in Figure 8, in the present invention, the tensioning structure 7 includes tooth plates 73 arranged in a cross shape on the internal angle steel 2, that is, there are four tooth plates 73 in the tensioning structure 7, the inner ends of the four tooth plates 73 converge at the same point but are not fixed to each other, and the four tooth plates 73 can be flipped relative to the surface of the internal angle steel 2 after being installed on the internal angle steel 2; at the same time, the four tooth plates 73 can be flipped on the internal angle steel 2, and the inner ends of the four tooth plates 73 are all provided with arc grooves 74. When the inner ends of the four tooth plates 73 converge at the same point, the arc grooves 74 at the inner ends of the four tooth plates 73 together form a complete circular hole, which corresponds to the tension anchor rod 4, and the diameter of the circular hole matches the diameter of the tension anchor rod 4, so that after the inner ends of multiple tooth plates 73 converge at the same point, the tension anchor rod 4 can normally pass through the circular hole formed by the arc grooves 74 at the inner ends of the four tooth plates 73. The inner end of the tension anchor rod 4 is also equipped with a pressing structure 5 that is pressed against the inner ends of multiple teeth 73 .

[0034] In the present invention, since the inner end of the steel plate 3 needs to pass through the through hole at the end of the steel plate 3, for the installation of the steel plate 3, the end of the steel plate 3 can be located between the internal angle steel 2 and the inner wall of the ancient tower. At this time, the inner end of the tension anchor rod 4 passes through the steel plate 3, the internal angle steel 2, and the tensioning structure 7 in sequence, and then the compression structure 5 is installed on the tension anchor rod 4, and the compression structure 5 locks the tension anchor rod 4 and the tensioning structure 7 together; in the present invention, for the installation of the steel plate 3, the end of the steel plate 3 can be located outside the compression structure 5. At this time, the inner end of the tension anchor rod 4 passes through the internal angle steel 2, the tensioning structure 7, and the steel plate 3 in sequence, and then the compression structure 5 is installed on the tension anchor rod 4, and the compression structure 5 locks the tension anchor rod 4 and the steel plate 3 together. Since the steel plate 3 is pressed on the tensioning structure 7 at this time, the inner ends of the four teeth 73 in the compression structure are also locked.

[0035] like Figure 5As shown, to ensure tensioning of the tension anchor 4, a compression spring 75 is also installed on the back of the tooth piece 73, or a compression spring 75 is installed on the internal angle steel 2 at a position corresponding to the tooth piece 73. When the inner ends of the four tooth pieces 73 in the tensioning structure 7 do not need to be brought together, the compression spring 75 is not compressed; when the inner ends of the four tooth pieces 73 in the tensioning structure 7 need to be brought together to form a circular hole for the tension anchor 4 to pass through, the compression spring 75 is compressed. When the inner ends of the four teeth 73 in the tensioning structure 7 converge to form a circular hole for the tension anchor rod 4 to pass through, the compression spring 75 is compressed, so that when the tension anchor bolt is locked with the tensioning structure 7 or the steel plate 3 through the compression structure 5, the elastic force of the compression spring 75 itself is applied to the tensioning structure 7, and the tensioning structure 7 is transmitted to the compression structure 5, so that the compression structure 5 is subjected to a thrust away from the internal angle steel 2. The compression structure 5 is fixed to the tension anchor rod 4, so that the tension anchor rod 4 is subjected to a pulling force toward the inside of the ancient tower, thereby tightening the external angle steel 1; at the same time, the elastic force of the compression spring itself also acts on the internal angle steel 2, so that the internal angle steel 2 is pressed against the ancient tower. Through the cooperation of the internal angle steel 2 and the external angle steel 1, the reinforcement effect of the ancient tower is greatly improved.

[0036] In order to ensure the stability of the tensioning structure 7, a diagonal rod 76 is hinged between two adjacent tooth plates 73, and the diagonal rod 76 and the tooth plates 73 can swing relative to each other; since the four tooth plates 73 in the tensioning structure 7 can be flipped, after the tooth plates 73 are flipped, the distance between the hinge points on the adjacent two tooth plates 73 that are hinged to the diagonal rod 76 changes. Therefore, in order to meet the change of this distance, the diagonal rod 76 is a retractable telescopic rod.

[0037] like Figure 5 As shown, in the present invention, in order to increase the swing range of the inclined rod 76 on the tooth plate 73, a ball socket 77 is further provided on the tooth plate 73, and the end of the inclined rod 76 is also provided with a rotating ball 78 that is clearance-matched with the ball socket 77. The rotating ball 78 is embedded in the ball socket 77 and can fully rotate in the ball socket 77; in order to prevent the rotating ball 78 from escaping from the ball socket 77, the opening of the ball socket 77 is smaller than the radius of the rotating ball 78.

[0038] In the present invention, in order to make the inner ends of the four tooth pieces 73 converge together to form a circular hole after the four tooth pieces 73 are flipped over, the force applied to the tooth piece 73 by the compression spring 75 can be dispersed as evenly as possible. At this time, the height of the end connected to the internal angle steel 2 can be raised so that the four tooth pieces 73 can remain flat when the inner ends of the four tooth pieces 73 converge together to form a circular hole. Specifically, a rotating base 71 corresponding to the four tooth pieces 73 in the tensioning mechanism can be installed on the flange of the internal angle steel 2. The rotating base 71 can be fixed to the internal angle steel 2 by welding or bolts, and a rotating base 71 can be installed on the rotating base 71. The movable shaft 72 fixes the tooth piece 73 on the rotating shaft 72, so that the tooth piece 73, the rotating shaft 72, and the rotating base 71 together form a hinge structure, so that the tooth piece 73 can be smoothly turned on the rotating base 71, thereby raising the installation height of the tooth piece 73. When the inner ends of the four tooth pieces 73 in the tensioning mechanism are brought together, the tooth piece 73 can remain parallel to the internal angle steel 2. At this time, there is a certain distance between the tooth piece 73 and the flange of the internal angle steel 2, and the compression spring 75 is adapted to this distance in the compressed state, ensuring that the compression spring 75 is in a compressed state when the inner ends of the four tooth pieces 73 in the tensioning mechanism are brought together. Because the tooth piece 73 remains parallel to the flange of the internal angle steel 2 in this case, and the compression spring 75 is installed vertically between the tooth piece 73 and the flange of the internal angle steel 2, so that the tooth piece 73 and the compression spring 75 are perpendicular, the elastic force of the compression spring 75 can be evenly applied to the tooth piece 73.

[0039] In order to ensure the fixation between the tension anchor rod 4 and the external angle steel 1, a clamping structure 6 is also installed on the outer end of the tension anchor rod 4 after the tension anchor rod 4 passes through the external angle steel 1, so that when the tension anchor rod 4 is subjected to a pulling force toward the inside of the ancient tower, the clamping structure 6 is pressed against the external angle steel 1, thereby pressing the external angle steel 1 against the outer wall of the ancient tower.

[0040] In the present invention, in order to facilitate the installation and disassembly of the reinforcement device, the compression structure 5 is installed on the tension anchor rod 4 in a detachable manner.

[0041] like Figure 6 As shown, in order to facilitate the installation and removal of the compression structure 5, the tension anchor 4 has annular grooves 41 evenly spaced along its axial direction. The compression structure 5 is a steel sheet 51. Figure 8As shown, a U-shaped notch 52 is also provided on the steel sheet 51. The opening width of the U-shaped notch 52 matches the diameter of the bottom of the annular groove 41. When the compression structure 5 needs to be installed, it can be directly clamped into the annular groove 41 of the tension anchor rod 4 through the U-shaped notch 52 on the steel sheet 51. After the steel sheet 51 is installed in the annular groove 41 of the tension anchor rod 4, the steel sheet 51 cooperates with the groove wall of the annular groove 41, so that the steel sheet 51 will not be separated from the tension anchor rod 4 even when it is subjected to the tension of the tension anchor rod 4 or the thrust applied by the compression spring 75. Therefore, the elastic force of the compression spring 75 can not only act on the internal angle steel 2, but also be transmitted to the compression structure 5 through the tooth plate 73, and act on the external angle steel 1 through the two compression structures 5 and the tension anchor rod 4, so that the internal angle steel 2 and the external angle steel 1 can jointly clamp the wall of the ancient tower, thereby reinforcing the ancient tower.

[0042] like Figure 3 As shown, in order to minimize the damage caused by the external angle steel 1 to the outer wall of the ancient tower, a rubber gasket 8 can be placed between the inner wall of the external angle steel 1 and the outer wall of the ancient tower; similarly, in order to minimize the damage caused by the internal angle steel 2 to the inner wall of the ancient tower, a rubber gasket 8 can be placed between the outer wall of the internal angle steel 2 and the inner wall of the ancient tower.

[0043] In the present invention, the flange length of the external angle steel 1 is greater than the length of the external angle steel 1, that is, the two flanges of the external angle steel 1 extend in the width direction of the two walls of the ancient tower respectively; at the same time, there are multiple external angle steels 1 on the edge of the outer wall of the ancient tower, and the multiple external angle steels 1 are arranged at intervals along the height direction of the ancient tower, and the spacing between two adjacent external angle steels 1 on the same edge of the outer wall of the ancient tower can be equal or unequal, that is, the spacing between two adjacent external angle steels 1 on the same edge of the outer wall of the ancient tower can be selected according to actual conditions.

[0044] In the present invention, since the outer width of the ancient pagoda wall is greater than the inner width of the ancient pagoda wall, when selecting the internal angle steel 2, the length direction of the internal angle steel 2 can be consistent with the axis direction of the internal corner of the ancient pagoda, so that only one angle steel needs to be installed in the corner of the ancient pagoda inner wall. At this time, multiple external angle steels 1 on the same edge of the ancient pagoda outer wall correspond to the internal angle steels 2 in the corner of the ancient pagoda inner wall. It should be noted that the multiple external angle steels 1 on the same edge of the ancient pagoda outer wall correspond to the internal angle steels 2 in the corner of the ancient pagoda inner wall. The ancient pagoda outer wall edge and the ancient pagoda inner wall corner in this description refer to the ancient pagoda outer wall edge and the ancient pagoda inner wall corner that correspond to each other.

[0045] like Figure 3 、 4As shown, in the present invention, since multiple external angle steels 1 are installed on the same edge of the outer wall of the ancient tower, and the internal angle steel 2 extends along the axial direction of the internal edge of the ancient tower, in order to tighten the internal angle steel 2 and the multiple external angle steels 1, the multiple external angle steels 1 on the same edge of the outer wall of the ancient tower and the internal angle steels 2 in the edge of the inner wall of the ancient tower are connected by tension anchor rods 4, that is, multiple through holes for the tension anchor rods 4 to pass through are opened on the flanges of the internal angle steel 2, and tensioning structures 7 corresponding to the multiple tension anchor rods 4 are also installed on the flanges of the internal angle steel 2.

[0046] In the present invention, there are multiple steel plates 3 connecting two adjacent internal angle steels 2, and the multiple steel plates 3 are arranged at intervals along the axial direction of the internal angle steel 2. Specifically, the spacing between two adjacent steel plates 3 can be equal or unequal, that is, the spacing between two adjacent steel plates 3 can be selected according to actual conditions.

[0047] In order to ensure the structural strength of the internal angle steel 2, as Figure 7 As shown, a plurality of reinforcing ribs 9 are further provided in the internal angle steel 2, and the plurality of reinforcing ribs 9 are arranged at intervals along the axial direction of the internal angle steel 2; the reinforcing ribs 9 are triangular, and the two sides of the reinforcing ribs 9 are respectively welded and fixed to the two flanges of the internal angle steel 2.

[0048] In order to facilitate the internal angle steel 2 to be stably supported on the ground, Figure 7 As shown, a pad 10 is welded to the lower end of the internal angle steel 2 and is in contact with the ground. Two triangular stiffening ribs 11 are welded to the pad 10 , and the other sides of the two stiffening ribs 11 are welded and fixed to the two flanges of the internal angle steel 2 .

[0049] When the ancient pagoda reinforcement device provided by the present invention is used to reinforce the ancient pagoda, the reinforcement method includes the following steps: (1) Select the inner angle steel 2 made of Q355, the outer angle steel 1 made of Q355, the steel plate 3, the tension anchor rod 4, and the steel sheet 51.

[0050] (2) Drill multiple holes on both sides of the four corners of the ancient tower body into the horizontal tower body, and arrange the multiple holes at intervals along the height direction of the ancient tower body, where the hole diameter is 5.2 cm; and reserve corresponding through holes on the two flanges of the internal angle steel 2, the two ends of the steel plate 3, and the two flanges of the external angle steel 1.

[0051] (3) Install the tensioning structure 7 on the two flanges of the internal angle steel 2. Specifically, fix the four rotating bases 71 in the tensioning structure 7 to the internal angle steel 2 by bolts or welding. When installing the four rotating bases 71, it is necessary to ensure that when the arc grooves 74 at the inner ends of the four tooth pieces 73 together form a complete circular hole, the center of the circular hole is in the same straight line with the center of the through hole on the flange of the internal angle steel 2.

[0052] (4) Pass the tension anchor rod 4 through the hole, and clamp the external angle steel 1 on the edge of the outer wall of the ancient tower, so that the outer end of the tension anchor rod 4 passes through the through hole on the flange of the external angle steel 1, and a rubber gasket 8 is placed between the external angle steel 1 and the outer wall of the ancient tower, and the clamping structure 5 is clamped on the annular groove 41 of the outer end of the tension anchor rod 4; the inner end of the tension anchor rod 4 passes through the steel plate 3; install the internal angle steel 2 in the edge of the inner wall of the ancient tower, and pass the tension anchor rod 4 through the through hole on the flange of the internal angle steel 2; flip the four tooth pieces 73 in the tensioning structure 7 so that the inner ends of the four tooth pieces 73 converge together, and the arc grooves 74 of the inner ends of the four tooth pieces 73 are clamped on the tension anchor rod 4 together, and the compression spring 75 is in a compressed state; clamp the clamping structure 5 on the annular groove 41 of the inner end of the tension anchor rod 4.

[0053] The present invention cooperates with the internal angle steel 2, the external angle steel 1, the tension anchor rod 4, the tensioning structure 7, and the two compression structures 5 to form an integral device for each component to complete the reinforcement of the ancient pagoda. This reinforcement device directly improves the shear strength of the ancient pagoda body. Due to the restraining effect of the internal angle steel 2, the steel plate 3, and the external angle steel 1, it can also improve the ultimate compressive strain and compressive strength of the mortar masonry material of the ancient pagoda body, effectively delaying the crushing and destruction process of the mortar masonry material. In addition, the restraining effect of the internal angle steel 2, the steel plate 3, and the external angle steel 1 on the ancient pagoda body greatly improves the anti-buckling ability of the internal angle steel 2 and the ancient pagoda body, thereby improving the ductile deformation ability of the ancient pagoda body.
