[0013] A method for using a vibration isolation structure for a hotel structure, comprising the following steps:

[0014] Step 1: Construction of lower pier:

[0015] 1. Carry out the construction of the steel bar formwork for the lower pier: place the embedded bolts, embedded anchor bolts and rectangular plates of the limit device according to the requirements of the drawings;

[0016] 2. Install and fix the reserved template box: This is used to place the shear key of the connecting plate of the limit device;

[0017] 3. Correct the installation position of embedded parts: When inspecting the steel bars, ensure that the plane position deviation of the embedded bolt 8 is within ±3mm, and the elevation deviation of the rectangular plate is within ±5mm;

[0018] 4. Pouring concrete for the lower column pier: During the concrete vibration process, it is strictly forbidden to collide with the rectangular plate and the embedded bolts, and it is forbidden to step directly on the rectangular plate to vibrate, so as to prevent the axis, elevation and levelness from deviation, which will affect the installation quality. The levelness of the top surface of the area where the spring vibration isolation support is installed is required to be less than 2mm / 1000mm, and the elevation error is ±5mm. The top surface of the column needs to be carefully leveled and inspected;

[0019] Step 2: Construction of horizontal limit device:

[0020] 1. Structural assembly: The cross-shaped steel column and its bolts, end plates, middle plates and stainless steel surfaces are assembled in place in the factory. The cross-shaped steel column is hoisted to the laid-out position of the lower pier 1 by a hoisting machine. The cross-shaped steel column should be able to pass through the embedded bolts smoothly. A 35mm thick pad is partially padded at the bottom of the cross-shaped steel column to reserve a gap. After the cross-shaped steel column is hoisted in place, temporary support and fixation should be done synchronously. The horizontal limit device should be removed after installation.

[0021] 2. Install the embedded plate of the limit device: the connecting plate is leveled and fixed with leveling nuts. The horizontality of the connecting plate is required to be less than 3mm / 1000mm, and the elevation error is ±5mm;

[0022] 3. Install the limit device: The support end of the limit device is against the stainless steel surface of the cross-shaped steel column. At this time, one end surface of the moving plate and one end surface of the connecting plate are in contact. At this time, the limit device 9 is positioned, and then spot welded on the connecting plate. After confirmation, perform full penetration welding at the reserved groove;

[0023] 4. After the welding temperature cools down: use high-strength grouting material to fill the reserved space at the bottom of the connecting plate, and the filling should be dense and without gaps;

[0024] Step 3: Installation of vibration isolation support:

[0025] 1. Marking (marking) the placement position of the vibration isolation support: After cleaning the top surface of the column, use ink lines to clearly mark the placement box of the spring vibration isolation support in accordance with the design requirements. The model of the spring vibration isolation support should be clearly marked in the box. At the same time, the size, position and direction of the box should meet the design requirements so that the spring vibration isolation support can be in place.

[0026] 2. Measure and record the elevation and flatness of the isolator position: mark five measuring points in the marked spring vibration isolation support placement range and number them in sequence (the five points are arranged at the four corners and the center of the spring vibration isolation support respectively), and then use the settlement observation instrument to measure the elevation. Based on the measurement results, control the elevation and flatness deviation of the spring vibration isolation support placement position. Control standards: the elevation deviation does not exceed +5.0mm, the flatness is less than 2mm / m, and the elevation deviation of adjacent piers is required to be in a relative position of ±5mm.

[0027] 3. Install the spring vibration isolation bearing: Before installing the spring vibration isolation bearing, check again its pre-stressed height, whether the locking bolts are loose, whether the nameplate information and quantity, and whether the installation position correspond one to one. If the locking bolts are loose, they must be re-corrected and tightened on site. Paste anti-slip pads on the bottom of the spring vibration isolation bearing, and then install the vibration isolator with anti-slip pads on the bottom, the middle anti-slip pads, the leveling steel plate, the upper anti-slip pads, and the textile pads in a total of 3 layers, respectively at the bottom of the spring vibration isolation bearing, the top of the spring vibration isolation bearing, and the top of the leveling pad.

[0028] 4. Finished product protection: After the above processes are accepted, the entire spring vibration isolation support is wrapped with a 0.04mm thick plastic film and wrapped tightly with a 40mm wide transparent tape. The plastic film is removed when the spring vibration isolation support is released;

[0029] Step 4: Construction of upper column pier:

[0030] 1. Install the upper column pier bottom membrane of the upper column pier, hoist the upper column pier bottom membrane to the upper part of the vibration isolator support, pass the middle hole through the cross-shaped steel column, check the positioning and elevation, and weld it to the cross-shaped steel column through the connecting steel sheet to avoid leakage;

[0031] 2. Weld the embedded parts on the vibration isolator to the designated position of the upper column pier bottom membrane and fix them, and set corresponding support measures at the bottom of the upper column pier bottom membrane;

[0032] 3. Carry out the construction of steel bars, formwork and concrete for the upper column pier;

[0033] Step 5: Leveling and release:

[0034] Leveling and release are carried out after the main load of the superstructure is applied.

[0035] The beneficial effects of the present invention are:

[0036] (1) The vibration isolation device consists of a spring vibration isolation support (bearing vertical load) and a limit device (bearing horizontal load), forming a dual protection for the structure in the vertical and horizontal directions. When facing multi-directional vibration or impact, the structure can maintain its own shape more stably, effectively resist the damage to the structure caused by external loads such as earthquakes and mechanical vibrations, and ensure the safety of life and property.

[0048] like Figure 2 and Figure 3 As shown, the cross-shaped steel column structure 6 includes an intermediate plate 63 fixedly installed inside the upper column pier bottom membrane 4, a cross-shaped steel 61 is welded to the top of the intermediate plate 63, end plates 62 are welded to the four end faces of the cross-shaped steel 61, and a stainless steel surface 64 is welded to the bottom end of the intermediate plate 63;

[0049] A cross-shaped steel 61 is welded to the top of the middle plate 63, and then the four end faces of the cross-shaped steel 61 are welded to the end plates 62. Then the stainless steel surface 64 and the middle plate 63 are welded to form a cross-shaped steel column structure 6, so that the assembled cross-shaped steel column structure 6 can be installed and fixed between the upper column pier bottom membrane 4 and the upper column pier 2.

[0050] like Figure 2 and Figure 3 As shown, a T-shaped column is fixedly installed on one end face of the end plate 62, the cross steel 61 and the end plate 62 are both arranged inside the upper column pier 2, and the embedded anchor bolt 11 is composed of a rectangular frame and an anchor bolt, wherein the top end of the rectangular frame and the bottom ends of the plurality of stainless steel surfaces 64 are welded and connected;

[0051] The installation of the pre-buried anchor bolts 11 and the cross-shaped steel column structure 6 can be facilitated, and the installation difficulty of the pre-buried anchor bolts 11 and the cross-shaped steel column structure 6 is reduced.

[0052] like Figure 4 , Figure 6 and Figure 7 As shown, the limiting device 9 includes an L-shaped I-beam 91 fixedly mounted on the top of the connecting plate 7, a slide support 93 is mounted on one end of the slide support 93 by screws, a stiffening plate 94 is fixedly mounted on one end of the slide support 93, an L-shaped steel 95 is slidably connected inside the L-shaped I-beam 91, and a moving plate 97 is slidably connected inside the L-shaped steel 95;

[0053] The movable plate 97 slides along the inside of the L-shaped steel 95 , so that the bottom end of the L-shaped steel 95 fits with the top end of the connecting plate 7 , thereby limiting the position of the L-shaped I-beam 91 , thereby changing the difficulty of positioning the L-shaped I-beam 91 .

[0054] like Figure 6 and Figure 7 The L-shaped I-beam 91 shown in the figure has an L-shaped hole inside, the L-shaped I-beam 91 is located inside the L-shaped hole, a reinforcing column 96 is symmetrically slidably connected inside the L-shaped I-beam 95, the reinforcing column 96 is fixedly installed inside the L-shaped I-beam 91, a guide column 98 is symmetrically embedded and installed at the bottom of the movable plate 97, the guide column 98 is slidably connected to the inside of the L-shaped I-beam 91, a rubber block 99 is embedded and installed at the top of the movable plate 97, a T-shaped groove is opened on one side of the inside of the L-shaped I-beam 91, and the shape of the movable plate 97 is T-shaped;

[0058] A method for using a vibration isolation structure for a hotel structure, comprising the following steps:

[0059] Step 1: Construction of lower pier:

[0060] 1. Carry out the construction of the lower column pier reinforcement formwork: place the embedded bolts 8 and embedded anchor bolts 11 of the limit device 9 and the rectangular plate according to the requirements of the drawing;

[0061] 2. Install and fix the reserved template box: This is used to place the shear key of the connecting plate 7 of the limit device 9;

[0062] 3. Correct the installation position of embedded parts: When inspecting the steel bars, ensure that the plane position deviation of the embedded bolt 8 is within ±3mm, and the elevation deviation of the rectangular plate is within ±5mm;

[0063] 4. Pouring concrete for the lower column pier: During the concrete vibration process, it is strictly forbidden to collide with the rectangular plate and the embedded bolts 8, and it is forbidden to step directly on the rectangular plate to vibrate, so as to prevent the axis, elevation and levelness from deviation, which will affect the installation quality. The levelness of the top surface of the area where the spring vibration isolation support 3 is installed is required to be less than 2mm / 1000mm, and the elevation error is ±5mm. The top surface of the column needs to be carefully leveled and checked;

[0064] Step 2: Construction of horizontal limit device:

[0065] 1. Structural assembly: The cross-shaped steel column 61 and its bolts, end plates 62, middle plates 63 and stainless steel surfaces 64 are assembled in place in the factory. The cross-shaped steel column 61 is hoisted to the laid-out position of the lower pier 1 by a hoisting machine. The cross-shaped steel column 61 should be able to pass through the embedded bolts 8 smoothly. A 35mm thick pad is partially padded at the bottom of the cross-shaped steel column 61 to reserve a gap. After the cross-shaped steel column 61 is hoisted in place, temporary support and fixation should be done synchronously. The horizontal limit device should be removed after installation.

[0066] 2. Install the embedded plate of the limit device: the connecting plate 7 is leveled and fixed with a leveling nut. The horizontality of the connecting plate 7 is required to be less than 3mm / 1000mm, and the elevation error is ±5mm;

[0067] 3. Install the limit device: The support end of the limit device 9 is against the stainless steel surface 64 of the cross-shaped steel column. At this time, one end face of the movable plate 97 is in contact with one end face of the connecting plate 7. At this time, the limit device 9 is positioned, and then spot welded on the connecting plate 7. After confirmation, full penetration welding is performed at the reserved groove;

[0068] 4. After the welding temperature cools down: use high-strength grouting material 12 to fill the reserved space at the bottom of the connecting plate 7, and the filling should be dense and without gaps;

[0069] Step 3: Installation of vibration isolation support:

[0070] 1. Marking and drawing of the vibration isolation bearing placement position: After cleaning the top surface of the column, use ink lines to clearly mark the placement box for the spring vibration isolation bearing 3 in accordance with the design requirements. The model of the spring vibration isolation bearing 3 is clearly marked in the box. At the same time, the size, position and direction of the box must meet the design requirements so that the spring vibration isolation bearing 3 can be in place.

[0071] 2. Measure and record the elevation and flatness of the isolator position: mark five measuring points in the marked placement range of the spring vibration isolation support 3 and number them in sequence. The five points are arranged at the four corners and the center of the spring vibration isolation support 3, and then the settlement observation instrument is used to measure the elevation. Based on the measurement results, the elevation and flatness deviation of the spring vibration isolation support 3 are controlled. The control standard is: the elevation deviation does not exceed +5.0mm, the flatness is less than 2mm / m, and the elevation deviation of adjacent piers is required to be in a relative position of ±5mm.

[0072] 3. Install the spring vibration isolation support: Before installing the spring vibration isolation support 3, check again its pre-stressed height, whether the locking bolts are loose, whether the nameplate information and quantity, and whether the installation position correspond one to one. If the locking bolts are loose, they must be re-corrected and tightened on site. Paste anti-slip pads on the bottom of the spring vibration isolation support 3, and then install the vibration isolator with anti-slip pads on the bottom, the middle anti-slip pads, the leveling steel plate, the upper anti-slip pads, and the textile pads in a total of 3 layers, respectively at the bottom of the spring vibration isolation support 3, the top of the spring vibration isolation support 3, and the top of the leveling pad.

[0073] 3. Finished product protection: After the above processes are accepted, the entire spring vibration isolation support 3 is wrapped with a 0.04mm thick plastic film and wrapped tightly with a 40mm wide transparent tape. The plastic film is removed when the spring vibration isolation support 3 is released;

[0074] Step 4: Construction of upper column pier:

[0075] 1. Install the upper column pier bottom membrane 4 of the upper column pier 2, hoist the upper column pier bottom membrane 4 to the upper part of the vibration isolator support 3, and pass the middle hole through the cross-shaped steel column 61. After checking that the positioning and elevation are correct, weld it to the cross-shaped steel column 61 through the connecting steel sheet to prevent leakage;

[0076] 2. Weld the embedded parts 5 on the vibration isolator to the designated position of the upper column pier bottom membrane 4 and fix them, and set corresponding support measures at the bottom of the upper column pier bottom membrane 4;

[0077] 3. Carry out the construction of steel bars, formwork and concrete for the upper column pier;

[0078] Step 5: Leveling and release:

[0079] After the main load of the upper structure is applied, leveling and release are carried out. Before the spring vibration isolation support 3 is released, the height of the spring and the entire height of the spring vibration isolation support 3 including the leveling steel plate are accurately measured and recorded with a micrometer. The release of the spring vibration isolation support 3 requires special tools, jacks and oil pumps. Place two jacks in the compartments on both sides of the top plate of the spring vibration isolation support 3, and use the oil pump to inject oil pressure. The jacks will further compress the spring vibration isolation support 3, and the locking bolts will be loosened. Loosen the locking nut to the bottom of the bolt, at least 30mm, and then pull out the adjustment steel plate thickness equivalent to the over-tightening pre-compression amount. The oil pump relieves pressure, and the spring vibration isolation support 3 enters the working state. Measure the spring height and the entire height of the spring vibration isolation support 3 including the leveling steel plate again. If they are consistent with the height before release, it means that the release is successful; if not, it is necessary to continue adjusting until they are consistent.

[0080] Working principle: During the actual assembly process of the device, the positions of the embedded anchor bolts 11 and the embedded bolts 8 are first placed according to the requirements of the drawings, and then a rectangular frame is placed on the outside, and a rectangular plate is set at the outside of the embedded bolts 8. Then cement is poured in to prepare the lower column pier 1, and then the rectangular plate is disassembled, and then the cross-shaped steel column structure 6 is assembled. At this time, the cross-shaped steel 61, the end plate 62, the middle plate 63 and the stainless steel surface 64 are spliced ​​and welded in sequence, and then the embedded anchor bolts 11 and the connecting plate 7 are installed, and then the limiting device 9 and the connecting plate 7 are installed. At this time, the movable plate 97 is pulled so that the movable plate 97 completely enters the L-shaped steel 95, and then the L-shaped steel 95 slides inside the L-shaped I-beam 91 through the guide column 98 under the action of gravity, and then fits with one end face of the connecting plate 7, and then the L-shaped The I-beam 91 is welded to the connecting plate 7, and then the grouting material 12 is filled at the connection between the connecting plate 7 and the lower column pier 1, and then the spring vibration isolation support 3 is installed. After the spring vibration isolation support 3 is installed, the upper column pier bottom membrane 4 is installed on its surface, and then the upper column pier bottom membrane 4 is welded to the cross-shaped steel column structure 6, and then the upper embedded part 5 is fixed to the upper column pier bottom membrane 4, and then the upper column pier 2 is cast, so as to complete an integral vibration isolation structure. The vibration isolation device is composed of a spring vibration isolation support 3 (bearing vertical load) and a limit device 9 (bearing horizontal load), forming a double protection for the structure in the vertical and horizontal directions, so that the structure can maintain its own shape more stably when facing multi-directional vibration or impact, effectively resist the damage to the structure caused by external loads such as earthquakes, explosions, and mechanical vibrations, and ensure the safety of life and property.

The vibration isolation structure for a hotel structure according to claim 1, characterized in that: The upper pier bottom mold (4) is in the shape of a circular shape, the cross-shaped steel column structure (6) is installed inside the hole of the upper pier bottom mold (4), and the spring vibration isolation support (3) is composed of a box body, a spring, and pre-tightening bolts.

9. A method for using the vibration isolation structure for a hotel structure according to claim 8, characterized in that: The following steps are involved: Step 1: Construction of lower pier:

1. Carry out the construction of the lower column pier reinforcement formwork: place the embedded bolts (8) and embedded anchor bolts (11) of the limit device (9) and the rectangular plate according to the requirements of the drawing; 2. Install and fix the reserved template box: This is used to place the shear key of the connecting plate (7) of the limit device (9); 3. Correct the installation position of embedded parts: When inspecting the steel bars, ensure that the plane position deviation of the embedded bolts (8) is within ±3mm and the elevation deviation of the rectangular plate is within ±5mm; 4. Pouring concrete for the lower column pier: During the concrete vibration process, it is strictly forbidden to collide with the rectangular plate and the embedded bolts (8), and it is forbidden to step directly on the rectangular plate to vibrate, so as to prevent the axis, elevation and levelness from deviating, which will affect the installation quality. The levelness of the top surface of the area where the spring vibration isolation support (3) is installed is required to be less than 2mm / 1000mm, and the elevation error is ±5mm. The top surface of the column needs to be carefully leveled and checked; Step 2: Construction of horizontal limit device:

1. Structural assembly: The cross-shaped steel column (61) and its bolts, end plates (62), middle plates (63) and stainless steel surfaces (64) are assembled in place in the factory. The cross-shaped steel column 61 is hoisted to the position where the lower pier (1) has been laid out by a hoisting machine. The cross-shaped steel column (61) should be able to pass through the embedded bolts (8) smoothly. A 35 mm thick pad is partially placed at the bottom of the cross-shaped steel column (61) to reserve a gap. After the cross-shaped steel column 61 is hoisted in place, temporary support and fixation should be done simultaneously. The horizontal limit device should be removed after installation.

2. Install the embedded plate of the limit device: the connecting plate (7) is leveled and fixed with a leveling nut. The horizontality of the connecting plate (7) is required to be less than 3mm / 1000mm, and the elevation error is ±5mm; 3. Install the limit device: The support end of the limit device (9) is against the stainless steel surface (64) of the cross-shaped steel column. At this time, one end surface of the movable plate (97) is in contact with one end surface of the connecting plate (7). At this time, the limit device (9) is positioned, and then spot welded on the connecting plate (7). After confirmation, full penetration welding is performed at the reserved groove; 4. After the welding temperature has cooled down: use high-strength grouting material (12) to fill the reserved space at the bottom of the connecting plate (7), and the filling should be dense and without gaps; Step 3: Installation of vibration isolation support:

1. Marking (marking) the placement position of the vibration isolation support: After the top surface of the column is cleaned, according to the design requirements, use ink lines to clearly mark the placement box of the spring vibration isolation support (3). The model of the spring vibration isolation support (3) is clearly marked in the box. At the same time, the size, position and direction of the box must meet the design requirements so that the spring vibration isolation support (3) can be placed in place.

2. Measure and record the elevation and flatness of the vibration isolator position: mark five measuring points in the marked placement range of the spring vibration isolation support (3) and number them in sequence (the five points are arranged at the four corners and the center of the spring vibration isolation support (3) respectively), then use a settlement observation instrument to measure the elevation. Based on the measurement results, control the elevation and flatness deviation of the placement position of the spring vibration isolation support (3). The control standard is: the elevation deviation does not exceed +5.0mm, the flatness is less than 2mm / m, and the elevation deviation of adjacent piers is required to be at a relative position of ±5mm.

3. Install the spring vibration isolation support: Before installing the spring vibration isolation support (3), check again its pre-stressed height, whether the locking bolts are loose, whether the nameplate information and quantity, and whether the installation position correspond to each other. If the locking bolts are loose, they must be corrected and tightened on site. Paste an anti-skid pad at the bottom of the spring vibration isolation support (3), and then install the vibration isolator with an anti-skid pad at the bottom, the middle anti-skid pad, the leveling steel plate, the upper anti-skid pad, and the textile pad in a total of 3 layers, respectively at the bottom of the spring vibration isolation support (3), the top of the spring vibration isolation support (3), and the top of the leveling pad.

4. Finished product protection: After the above processes are accepted, the entire spring vibration isolation support (3) is wrapped with a 0.04 mm thick plastic film and tightly wrapped with a 40 mm wide transparent tape. The plastic film is removed when the spring vibration isolation support (3) is released; Step 4: Construction of upper column pier:

1. Install the upper column pier bottom membrane (4) of the upper column pier (2), hoist the upper column pier bottom membrane (4) to the upper part of the vibration isolator support (3), pass the middle hole through the cross-shaped steel column (61), check that the positioning and elevation are correct, and then weld it to the cross-shaped steel column (61) through a connecting steel sheet to prevent slurry leakage; 2. Weld the embedded parts (5) on the vibration isolator to the designated position of the upper column pier bottom membrane (4) and fix them, and provide corresponding support measures at the bottom of the upper column pier bottom membrane (4); 3. Carry out the construction of steel bars, formwork and concrete for the upper column pier; Step 5: Leveling and release: Leveling and release are carried out after the main load of the superstructure is applied.
