[0032] The most commonly used method to reinforce ancient city walls is to fill the inside with plain soil and tamp it down, and then cover the outside with blue bricks. This reinforcement method only considers the outer wall of the city wall, and does not take into account the gate openings of the city wall where the force is most concentrated and the weakest part. Therefore, the gate openings of the city wall after reinforcement still cannot avoid the phenomenon of weak areas and stress concentration. Therefore, over time, collapse and damage are inevitable.

[0033] In view of this, the present invention discloses an ancient city gate protection and support device 1000, which can provide a reinforcement structure for the ancient city wall door opening to reduce stress concentration in the door opening of the ancient building. Figures 1 to 4 This is an embodiment of the ancient city gate protection and support device 1000 of the present invention (hereinafter referred to as "this embodiment").

[0034] The present invention provides an ancient city gate protection and support device 1000, which is used to support and protect the gate pivot opening of an ancient city tower. The ancient city gate protection and support device 1000 includes a support assembly, which includes two cast-in-place piles 1 and a curved top plate 3. The two cast-in-place piles 1 are arranged on both sides of the gate pivot opening. Each cast-in-place pile 1 is used to pass through the city body 7 of the ancient city tower from the roof of the ancient city tower to be inserted into the foundation. A crossbeam 2 spanning both sides of the gate pivot opening is arranged between the pile tops of the two cast-in-place piles 1. The curved top plate 3 includes an arc segment 31 and two connecting segments 32 respectively arranged at both ends of the arc segment 31. The arc segment 31 is arranged on the lower side of the top of the gate pivot opening. Each connecting segment 32 is used to be inserted into the city body 7 of the ancient city tower to connect the cast-in-place piles 1.

[0035] The ancient city gate protection and support device 1000 provided by the present invention is a frame structure formed by bored piles 1, cross beams 2 and curved top plates 3 arranged in the city body 7 around the gate pivot opening. It can be better combined with the city body 7 to share the stress at the gate opening. Specifically, the bored piles 1 on both sides of the gate pivot opening pass through the city body 7 of the ancient city up and down, which can reinforce the city body 7 on both sides of the gate pivot opening as a whole. The cross beam 2 is used to connect the bored piles 1 on both sides into a whole. At the same time, the curved top plate 3 passes through the city body 7 to connect the bored piles 1, which can directly transmit the force supporting the city body 7 and the force on the arch of the gate pivot opening to the foundation, so as to solve the problem that the original ancient city body 7 does not have internal protection support and the problem that the stress concentration in the city wall gate opening cannot be alleviated.

[0036] It should be added that the bored pile 1 is drilled manually layer by layer using a pickaxe and a shovel, and when encountering a hard soil layer, it is broken by a hammer, a chisel or a jackhammer. The first section of the hole is excavated manually, and then an inner isolation layer is set in the first section of the hole, and finally a concrete retaining wall is set in the first section of the hole. After the construction of the first section of the hole is completed, the second section of the hole, the third section of the hole, ..., the nth section of the hole are constructed in the same way. After the construction of the entire hole is completed, the concrete pouring can be started.

[0037] In order to ensure that the support assembly is evenly stressed, in this embodiment, the two cast-in-place piles 1 in the same support assembly are symmetrically arranged on both sides of the door swing opening, and in order to ensure the overall consistency of the door swing opening, the support assembly is provided in plurality, and the plurality of support assemblies are spaced apart in the length direction of the door swing opening. It should be added that connecting parts can be added between two adjacent support assemblies to ensure that the overall city body 7 around the door swing opening is fully reinforced. For example, a longitudinal beam can be added to the pile heads of two adjacent cast-in-place piles 1 on the same side, or a connecting rod can be provided between two adjacent curved top plates 3. In this way, the consistency of the plurality of support assemblies is good, the force is evenly distributed, and there will be no local weak areas.

[0038] In order to facilitate the connection of the curved top plate 3 and the bored pile 1 as one body, a receiving groove 11 is provided on the side of the bored pile 1 close to the door hinge opening, and one end of the connecting section 32 is inserted into the receiving groove 11 to connect the bored pile 1 and the curved top plate 3. In actual operation, a drilling machine can be used to drill a hole on the inner side of the door hinge opening toward the bored pile 1 to open the receiving groove 11 on the bored pile 1. However, it should be noted that the depth of the receiving groove 11 should preferably not exceed half the diameter of the bored pile 1 to avoid affecting the structural strength of the bored pile 1. After drilling is completed, the connecting section 32 of the curved top plate 3 is inserted into the hole to extend into the receiving groove 11. In this way, the curved top plate 3 and the bored pile 1 are connected as one body, and supported by the bored pile 1 to alleviate the stress concentration at the door hinge opening.

[0039] To further alleviate stress concentration at the door hinge opening, in this embodiment, the support assembly further includes two support columns 4, each of which is provided corresponding to a connecting section 32 to push upward against the curved top plate 3. Specifically, one end of the support column 4 is provided on the foundation below the door hinge opening, and the other end extends upward to the underside of the connecting section 32 of the curved top plate 3 to provide an upward supporting force to the curved top plate 3. This allows the support columns 4, like the cast-in-place piles 1, to disperse stress at the arch of the door hinge opening, further strengthening the supporting and fixing function of the ancient city gate protection support device 1000.

[0040] Furthermore, in order to ensure good structural consistency of the support assembly as a whole, the support column 4 includes a first insertion section 41 and a second insertion section 42 connected to the first insertion section 41. One end of the first insertion section 41 is used to insert into the foundation, and the second insertion section 42 is pushed upward against the connecting section 32 and inserted into the receiving groove 11 to connect the support column 4 and the cast-in-place pile 1. With this arrangement, the support column 4, the cast-in-place pile 1 and the arc-shaped top plate 3 form a whole, which can jointly ensure the overall complete reinforcement of the door hinge opening without the occurrence of local weak areas.

[0041] Considering that the door hinge of the ancient city gate may collapse downward during long-term use, in other embodiments of the present invention, one end of the arc-shaped top plate 3 is a free end, so as to facilitate the change of the distance between the two ends of the arc-shaped top plate 3, thereby changing the height of the arc-shaped top plate 3 to provide greater support force to the top of the door hinge. For further information, please refer to Figure 3 The ancient city gate protection and support device 1000 also includes a transmission structure 8, which includes a motor 81, a gear 82 and a rack 83 meshing with the gear 82, wherein the motor 81 is used to drive the gear 82 to rotate, and the rack 83 is used to drive the free end of the arc-shaped top plate 3 to move. In order to facilitate installation and simplify the mechanism, a first pulley is installed on the output shaft of the motor 81, and the gear 82 is installed on the supporting column 4 through a second pulley. The first pulley and the second pulley are connected by a belt. With such an arrangement, when the height of the arc-shaped top plate 3 needs to be adjusted, it is only necessary to turn on the motor 81 to drive the gear 82 to rotate. The rack 83 can be translated or moved toward the inner side of the door hinge opening during the rotation of the gear 82, so that the arc-shaped top plate 3 has a larger curvature to support the top of the door hinge opening upward.

[0042] The present invention also provides a debugging method for the transmission structure 8, the debugging method comprising:

[0043] S1. Monitor the deformation of the top of the door opening;

[0044] The deformation amount of the top of the door hinge opening can be obtained by measuring the gap distance in the height direction between the top of the door hinge opening and the arc-shaped portion of the arc-shaped top plate 3.

[0045] S2. When the deformation variable is greater than a preset value, query the mapping relationship to determine the lateral displacement parameter, wherein the mapping relationship is the association relationship between the deformation variable and the lateral displacement parameter;

[0046] Among them, the preset value is the maximum value allowed by the deformation amount, and the lateral displacement parameter is calculated based on multiple sets of data measurements of the moving distance of the arc segment 31 in the height direction and the distance of the connecting segment 32 translated toward the inner side of the door opening.

[0047] S3. Determine the operating parameters of the motor 81 according to the lateral movement parameters;

[0048] The operating parameters include the rotation speed and operating time of the motor 81 .

[0049] S4. Control the motor 81 to operate according to the operating parameters.

[0050] In order to fix the curved top plate 3 and the supporting column 4, the ancient city gate protection support device 1000 also includes an anchor 5, and the anchor rod of the anchor 5 passes through the curved top plate 3 and the supporting column 4 to lock the curved top plate 3 and the supporting column 4. Since the supporting column 4 and the curved top plate 3 are an upper and lower structure, when setting the anchor 5, in order to achieve a better fixing effect, a special anchor 5 structure can be adopted. Specifically, in the present invention, the anchor 5 includes a fixing plate, a fixing column and a plurality of limiting pieces. The fixing plate is arranged on one side of the supporting column 4, the fixing column and the fixing plate are arranged obliquely, and a plurality of limiting pieces are arranged along the circumferential direction of the fixing column. The fixing column forms the anchor rod. During installation, the anchor 5 can be provided on the supporting column 4, and the anchor rod obliquely passes through the connecting section 32 between the supporting column 4 and the arc-shaped top plate 3 from bottom to top. Alternatively, the anchor 5 can be provided on the connecting section 32 of the arc-shaped top plate 3, and the anchor rod obliquely passes through the connecting section 32 of the arc-shaped top plate 3 and the supporting column 4 from top to bottom. The limiting plate is generally made of elastic material and can follow the tip of the anchor 5 into the object. When shaking occurs, the anchor 5 can be clamped in a fixed position to avoid the misalignment of the arc-shaped top plate 3 and the supporting column 4, resulting in local stress concentration. In other embodiments, the anchor 5 can also be replaced by other connecting parts, such as a connecting plate. The specific structure of the connecting plate can refer to the existing technology and will not be described in detail here.

[0051] In order to fix the anchor body on the supporting column 4, an installation hole is opened on the fixing plate, and the installation hole is used for the expansion screw to pass through to anchor the anchor. In view of this, the present invention discloses an ancient city gate protection support device 1000, which can provide a reinforcement structure for the ancient city wall door opening that reduces the stress concentration of the ancient building door opening. Figure 1 This is an embodiment of the ancient city gate protection and support device 1000 of the present invention (hereinafter referred to as "this embodiment").

[0052] The present invention provides an ancient city gate protection and support device 1000, which is used to support and protect the gate pivot opening of an ancient city tower. The ancient city gate protection and support device 1000 includes a support assembly, which includes two cast-in-place piles 1 and a curved top plate 3. The two cast-in-place piles 1 are arranged on both sides of the gate pivot opening. Each cast-in-place pile 1 is used to pass through the city body 7 of the ancient city tower from the roof of the ancient city tower to be inserted into the foundation. A crossbeam 2 spanning both sides of the gate pivot opening is arranged between the pile tops of the two cast-in-place piles 1. The curved top plate 3 includes an arc segment 31 and two connecting segments 32 respectively arranged at both ends of the arc segment 31. The arc segment 31 is arranged on the lower side of the top of the gate pivot opening. Each connecting segment 32 is used to be inserted into the city body 7 of the ancient city tower to connect the cast-in-place piles 1.

[0053] The ancient city gate protection and support device 1000 provided by the present invention is a frame structure formed by bored piles 1, cross beams 2 and curved top plates 3 arranged in the city body 7 around the gate pivot opening. It can be better combined with the city body 7 to share the stress at the gate opening. Specifically, the bored piles 1 on both sides of the gate pivot opening pass through the city body 7 of the ancient city up and down, which can reinforce the city body 7 on both sides of the gate pivot opening as a whole. The cross beam 2 is used to connect the bored piles 1 on both sides into a whole. At the same time, the curved top plate 3 passes through the city body 7 to connect the bored piles 1, which can directly transmit the force supporting the city body 7 and the force on the arch of the gate pivot opening to the foundation, so as to solve the problem that the original ancient city body 7 does not have internal protection support and the problem that the stress concentration in the city wall gate opening cannot be alleviated.

[0054] It should be added that the bored pile 1 is drilled manually layer by layer using a pickaxe and a shovel, and when encountering a hard soil layer, it is broken by a hammer, a chisel or a jackhammer. The first section of the hole is excavated manually, and then an inner isolation layer is set in the first section of the hole, and finally a concrete retaining wall is set in the first section of the hole. After the construction of the first section of the hole is completed, the second section of the hole, the third section of the hole, ..., the nth section of the hole are constructed in the same way. After the construction of the entire hole is completed, the concrete pouring can be started.

[0055] In order to ensure that the support assembly is evenly stressed, in this embodiment, the two cast-in-place piles 1 in the same support assembly are symmetrically arranged on both sides of the door swing opening, and in order to ensure the overall consistency of the door swing opening, the support assembly is provided in plurality, and the plurality of support assemblies are spaced apart in the length direction of the door swing opening. It should be added that connecting parts can be added between two adjacent support assemblies to ensure that the overall city body 7 around the door swing opening is fully reinforced. For example, a longitudinal beam can be added to the pile heads of two adjacent cast-in-place piles 1 on the same side, or a connecting rod can be provided between two adjacent curved top plates 3. In this way, the consistency of the plurality of support assemblies is good, the force is evenly distributed, and there will be no local weak areas.

[0056] In order to facilitate the connection of the curved top plate 3 and the bored pile 1 as one body, a receiving groove 11 is provided on the side of the bored pile 1 close to the door hinge opening, and one end of the connecting section 32 is inserted into the receiving groove 11 to connect the bored pile 1 and the curved top plate 3. In actual operation, a drilling machine can be used to drill a hole on the inner side of the door hinge opening toward the bored pile 1 to open the receiving groove 11 on the bored pile 1. However, it should be noted that the depth of the receiving groove 11 should preferably not exceed half the diameter of the bored pile 1 to avoid affecting the structural strength of the bored pile 1. After drilling is completed, the connecting section 32 of the curved top plate 3 is inserted into the hole to extend into the receiving groove 11. In this way, the curved top plate 3 and the bored pile 1 are connected as one body, and supported by the bored pile 1 to alleviate the stress concentration at the door hinge opening.

[0057] To further alleviate stress concentration at the door hinge opening, in this embodiment, the support assembly further includes two support columns 4, each of which is provided corresponding to a connecting section 32 to push upward against the curved top plate 3. Specifically, one end of the support column 4 is provided on the foundation below the door hinge opening, and the other end extends upward to the underside of the connecting section 32 of the curved top plate 3 to provide an upward supporting force to the curved top plate 3. This allows the support columns 4, like the cast-in-place piles 1, to disperse stress at the arch of the door hinge opening, further strengthening the supporting and fixing function of the ancient city gate protection support device 1000.

[0058] Furthermore, in order to ensure good structural consistency of the support assembly as a whole, the support column 4 includes a first insertion section 41 and a second insertion section 42 connected to the first insertion section 41. One end of the first insertion section 41 is used to insert into the foundation, and the second insertion section 42 is arranged to overlap with the connecting section 32 from bottom to top, and is inserted into the accommodating groove 11 to connect the support column 4 and the cast-in-place pile 1. In this way, the support column 4, the cast-in-place pile 1 and the curved top plate 3 form a whole, which can jointly ensure the overall complete reinforcement of the door hinge opening without the occurrence of local weak areas.

[0059] In order to fix the curved top plate 3 and the supporting column 4, the ancient city gate protection support device 1000 also includes an anchor 5, and the anchor rod of the anchor 5 passes through the curved top plate 3 and the supporting column 4 to lock the curved top plate 3 and the supporting column 4. Since the supporting column 4 and the curved top plate 3 are an upper and lower structure, when setting the anchor 5, in order to achieve a better fixing effect, a special anchor 5 structure can be adopted. Specifically, in the present invention, the anchor 5 includes a fixing plate, a fixing column and a plurality of limiting pieces. The fixing plate is arranged on one side of the supporting column 4, the fixing column and the fixing plate are arranged obliquely, and the plurality of limiting pieces are arranged at intervals along the circumference of the fixing column, wherein the The fixing column forms the anchor rod of the anchor 5. During installation, the anchor 5 can be provided on the supporting column 4, and the anchor rod of the anchor 5 obliquely penetrates the connecting section 32 between the supporting column 4 and the arc-shaped top plate 3 from bottom to top. Alternatively, the anchor 5 can be provided on the connecting section 32 of the arc-shaped top plate 3, and the anchor rod of the anchor 5 obliquely penetrates the connecting section 32 of the arc-shaped top plate 3 and the supporting column 4 from top to bottom. The limiting plate is generally made of elastic material and can follow the tip of the anchor 5 into the object. When shaking occurs, the anchor 5 can be clamped in a fixed position to avoid the misalignment of the arc-shaped top plate 3 and the supporting column 4, which leads to the occurrence of local stress concentration. In other embodiments, the anchor 5 can also be replaced by other connecting parts, such as a connecting plate. The specific structure of the connecting plate can refer to the existing technology and will not be described in detail here.

[0060] In order to fix the anchor body to the support column 4, the fixing plate is provided with a mounting hole for passing an expansion screw to lock the anchor body 5 to the support column 4. In other embodiments, the expansion screw can also be replaced by a bolt.

[0061] To prevent the curved top plate 3 from directly contacting the wall 7 and causing wear, a buffer structure 6 is provided between the curved segment 31 and the top of the door opening. In one embodiment, the reinforcement layer includes a basalt fiberboard made of basalt fiber material.
