Description

Technical Field

[0001] The invention relates to the technical field of building movement, and in particular to a device and method for adding a seismic isolation platform to stone cultural relics. Background Art

[0002] Conventional existing stone cultural relics are generally located on a ground cushion or a concrete foundation, and are usually moved and transported by conventional hoisting methods, and floated on a seismic isolation platform to protect them from the harm of earthquakes or huge external vibrations. The above method has the following disadvantages: 1. It adopts the traditional bottom-covering or bundling lifting method, and cooperates with gantry crane, automobile crane and forklift to lift it to the seismic isolation platform. During the operation, the tilt state of the cultural relics and the speed and acceleration generated will cause great disturbance to the stone cultural relics. This method is not suitable for stone cultural relics with many cracks and incomplete bodies (there are cracks and repairs on the cultural relics). 2. This method can only be used in places with spacious space. For stone cultural relics in a small space, its applicability is poor; 3. For some stone cultural relics, the traditional transportation method is to add steel beams or concrete beams underneath them, move and transport them by lifting steel beams or concrete beams, and place them on the seismic isolation platform. After they are in place, the steel beams or concrete beams cannot be taken out, which increases the height of the cultural relics, thereby directly affecting the viewing angle; 4. The conventional method is to float the stone cultural relics on the seismic isolation platform after transporting them. There is no effective connection between the cultural relics and the device, which indirectly affects the seismic isolation (vibration) effect. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a device and method for adding a seismic isolation platform to stone cultural relics, which can ensure the stability of the stone cultural relics during movement, and the device can be effectively connected to the stone cultural relics, thereby increasing the integrity and ensuring the seismic (vibration) isolation effect.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0034] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Embodiment 1:

[0036] The bottom of the stone cultural relic stele body 1 is a stone cultural relic base 3, and a frame 2 is arranged on the outside to protect the stone cultural relic to a certain extent; in order to add a seismic isolation platform 10 at the bottom of the stone cultural relic base 3, this embodiment provides a device for adding a seismic isolation platform to a stone cultural relic, such as Figure 1-Figure 3 As shown, it includes a screw rod 4 and a supporting structure, and multiple screw rods 4 are arranged on the lower side of the stone cultural relic base 3; in this embodiment, the screw rod 4 is arranged in the horizontal direction, and its length direction is consistent with the length direction of the stone cultural relic base 3, and multiple screw rods 4 are evenly distributed in the width direction of the stone cultural relic base 3 to form a support for the stone cultural relic.

[0037] The underpinning structures are symmetrically arranged on both sides of the stone cultural relics, and the underpinning structures are connected to the ends of the screw rods 4; a plurality of lifting components 9 are evenly distributed on the lower side of each underpinning structure, so that the device and the stone cultural relics can be lifted or lowered by the lifting components 9.

[0038] like Figure 1-Figure 3 As shown, the supporting structure includes a horizontal plate 5, a vertical plate 6 and a rib plate 12. The vertical plate 6 is connected to the screw rod 4, and the stone cultural relic base 3 is fitted with the inner surface of the vertical plate 6. The vertical plates 6 on both sides are used to clamp the stone cultural relic base 3, so that the stone cultural relic remains stable during the movement. The screw rod 4 is connected to the bottom ends of the two vertical plates 6, and the screw rod 4 is fixed to the vertical plates 6 by nuts. Prestress is applied to the screw rod 4 to ensure that the stone cultural relic base 3 does not bear tension during the transportation process. An angle steel 8 is set at the connection between the screw rod 4 and the vertical plate 6. The angle steel 8 has a certain length along the length direction of the vertical plate 6, and the angle steel 8 is located on the upper side of the screw rod 4. The angle steel 8 plays a role in supporting the weight of the stone cultural relic.

[0039] The horizontal plate 5 is arranged at a certain height of the vertical plate 6, for example, the horizontal plate 5 is arranged in the middle of the vertical plate 6; and a plurality of ribs 12 are connected between the horizontal plate 5 and the vertical plate 6 to ensure the structural strength of the entire underpinning structure. Figure 2 As shown, ribs 12 are provided on the upper and lower sides of the horizontal plate 5, and the ribs 12 on the upper and lower sides of the horizontal plate 5 can be aligned or staggered.

[0040] In order to increase the integrity of the components of the underpinning structure, a horizontal plate 5 is also provided at the bottom of the vertical plate 6. In addition, a guide rail assembly can be installed between the horizontal plate 5 at the bottom and the concrete track pad 13 to achieve horizontal movement of the stone cultural relics. The thrust for horizontal movement comes from the horizontal pushing component, which is also implemented by a jack in this embodiment.

[0041] In this embodiment, each plate member in the underpinning structure is made of steel plates. Of course, in other embodiments, other metal plates may also be used as long as the supporting performance can be guaranteed.

[0042] In order to ensure the stability and bearing capacity of the entire device, the top ends of the two vertical plates 6 are connected by a plurality of connecting rods 7. In this embodiment, the connecting rods 7 are square tubes, and the lifting components 9 are jacks. The top ends of the jacks are in contact with the horizontal plates 5 located at a certain height of the vertical plates 6, and the horizontal plates 5 are connected with at least two jacks to ensure the support stability; the bottom ends of the jacks are arranged on the concrete track pad 13.

[0043] Since the guide rail assembly is installed between the concrete track cushion layer 13 and the underpinning structure, the stone cultural relics move under the action of the horizontal pushing component, and after moving to the set position, the seismic isolation platform 10 is installed. During the installation process, the stone cultural relics can be lifted or lowered in cooperation with the vertical jack. The vertical jacks of this embodiment are all connected to the hydraulic control system, and the PLC is used to synchronously control the jacks; and the horizontally arranged jacks are also connected to the hydraulic control system.

[0044] like Figure 4 and Figure 5 As shown, after removing the supporting structure, a connecting piece is installed in a direction perpendicular to the screw rod 4. The connecting piece adopts an angle steel 8. The vertical flange of the angle steel 8 is connected to the screw rod 4, and the horizontal flange is connected to the seismic isolation platform 10 through a fixed pressure plate 11; wherein the fixed pressure plate 11 is a plate with a certain length, which presses the horizontal flange of the angle steel 8 and is connected to the seismic isolation platform 10 through bolts; thereby, the stone cultural relic and the seismic isolation platform 10 are connected as a whole, thereby achieving the purpose of effective seismic (vibration) isolation.

[0045] In this embodiment, the combined structure of the plate and the screw 4 can support the weight of the stone cultural relic and firmly fix the stone cultural relic base 3; a frame 2 is installed on the outside of the stone cultural relic stele body 1, and the frame 2 is made of a steel pipe. The frame 2 is welded to the supporting structure to ensure its stability during the movement process.

[0046] The combined structure of the plate and the screw rod 4 in this embodiment cooperates with the jack to move the stone cultural relics, which can effectively control the speed, acceleration and body state of the stone cultural relics during the operation, and is suitable for stone cultural relics with many cracks and incomplete bodies. The transportation process is safe and stable, and the additional stress on the stone cultural relics is low. It has good applicability and operability for stone cultural relics in a small space.

[0047] This embodiment applies prestress to the bottom screw 4 to avoid tension on the stone cultural relic base 3, which is particularly suitable for stone cultural relics with low tensile bearing capacity or cracked bases, ensuring the safety of the stone cultural relic movement process; and the screw 4 is installed at the bottom of the stone cultural relic to reduce the thickness of the bottom as much as possible, which increases the height of the body of the cultural relic less and ensures the viewing effect. After transportation, the screw 4 at the bottom of the stone cultural relic is effectively connected to the seismic isolation platform 10, which increases the integrity and ensures the seismic isolation (vibration) effect.

[0048] Embodiment 2:

[0049] This embodiment provides a method for adding a seismic isolation platform to a stone cultural relic, using the device described in Embodiment 1, specifically comprising the following steps:

[0050] Step 1: Perform surface protection on the entire stone cultural relic; break the ground and excavate the earth around the stone cultural relic base 3. After the excavation is completed, pour the concrete track cushion 13 to provide a working surface for the subsequent installation of the screw 4 and the underpinning structure.

[0051] Step 2: Install screw 4:

[0052] On the ground cushion or concrete foundation at the bottom of the stone cultural relic, use a drilling device to drill holes from one side to the other side in the vertical projection area of ​​the stone cultural relic base 3. The drilled holes are one-way holes, all holes are in the same horizontal plane and remain parallel; each hole should be close to the bottom of the stone cultural relic base 3; the axial spacing between the holes is the same as the axial spacing of the screw 4; the drilled hole diameter is larger than the diameter of the screw 4, for example, the drilled hole diameter is 20mm larger than the diameter of the screw 4.

[0053] After the drilling is completed, a certain number of high-strength screws 4 are installed close to the bottom of the stone cultural relic base 3. In this embodiment, the screw 4 is provided with a casing (the screw 4 passes through the casing), lubricating oil is poured into the casing, and the gap between the hole and the casing is filled with grouting material; after the grouting material reaches the designed strength, the next process is entered.

[0054] Of course, in other embodiments, a plastic film may be wrapped around the screw 4 and then installed into the channel.

[0055] In this embodiment, the screw rods 4 are arranged unidirectionally and are located in the projected area directly below the stone cultural relic base 3. All the screw rods 4 are in the same horizontal plane and remain parallel. Each screw rod 4 should be close to the bottom of the stone cultural relic base 3. The diameter and number of the screw rods 4 are determined based on the weight of the stone cultural relic and the supporting structure.

[0056] Step 3: Install the underpinning structure:

[0057] The underpinning structure is welded by horizontal plates 5, vertical plates 6, and rib plates 12. The underpinning structure is installed on both sides of the stone cultural relic base 3 (both ends of the screw rod 4) at the same time, and the connection of the plates is all through split-through welding. The upper part of the underpinning structure is connected by square tube welding; the lower part of the underpinning structure needs to drill the same number of holes as the screw rod 4, and install nuts and pads. After the underpinning structure is installed, prestress is applied to the screw rod 4. The size of the prestress should be determined by calculation to ensure that the stone cultural relic base 3 is not subjected to tension during transportation.

[0058] An angle steel 8 is installed at each connection between the stone cultural relic base 3 and the screw rod 4. The angle steel 8 is on the upper part of the screw rod 4 to support the weight of the stone cultural relic. After the installation of the underpinning structure is completed, it is necessary to ensure that the side of the stone cultural relic base 3 is closely fitted with the vertical plate 6 to ensure the safety and stability of the stone cultural relic during the movement process.

[0059] Step 4: Install the PLC multi-point synchronous hydraulic control system:

[0060] A vertically arranged jack is installed between the underpinning structure and the concrete track cushion layer 13, and the top of the jack contacts the horizontal plate 5 at a certain height outside the vertical plate 6. The vertically arranged jack is controlled by the PLC multi-point synchronous hydraulic control system to tighten the horizontal plate 5; the tightening force is set according to 0.6 to 0.8 of the total weight of the stone cultural relics and the device, so that the stone cultural relics can be lifted and lowered.

[0061] A guide rail assembly is installed between the horizontal plate 5 at the bottom of the underpinning structure and the concrete track pad 13, and a horizontal jack is installed at one end of the underpinning structure. The horizontal jack is controlled by a PLC multi-point synchronous hydraulic control system to tighten the vertical plate 6, so that the stone cultural relics can be moved horizontally.

[0062] Step 5: Cut and separate the stone cultural relic base 3 from the original foundation:

[0063] A diamond chain saw system was used for horizontal hydrostatic cutting to separate the stone artifacts from the substructure.

[0064] Step 6: Lift, lower and translate the stone cultural relics:

[0065] The PLC multi-point synchronous hydraulic control system is used to control the jack to move the stone cultural relics to the designated position. The moving methods include lifting, lowering and translation. The displacement error between the jacks during the moving process is less than 2mm. The horizontal speed of the jack is controlled within 60mm / min and the lifting and lowering speed is controlled within 10mm / min to ensure the safety of the stone cultural relics.

[0066] Step 7: Install the seismic isolation platform 10:

[0067] After the stone cultural relic is moved to the designated position, an isolation platform 10 is installed underneath it; after the supporting structure is removed, a connecting piece, namely, an angle steel 8, is installed in a direction perpendicular to the screw rod 4. The vertical flange of the angle steel 8 is connected to the screw rod 4, and the horizontal flange of the angle steel 8 is connected to the isolation platform 10 through a fixed pressure plate 11, thereby connecting the stone cultural relic and the isolation platform 10 into a whole, achieving the purpose of effective isolation (vibration).

[0068] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
