Description

Technical Field

[0001] This invention relates to the field of ship open deck installation technology, specifically to a ship open deck with vibration isolation floor and a method for laying the vibration isolation floor. Background Technology

[0002] As is well known, vibration damping pads are generally laid in the open deck areas of passenger ships. The purpose of these pads is primarily to isolate vibrations generated by people walking on the deck from being transmitted to the cabins, such as the sound of high heels hitting the deck. Classification societies have strict control over this vibration noise and require impact tests to verify the effectiveness of the vibration damping pads. To meet the requirements for vibration and sound insulation, shipyards choose perforated vibration damping pads made of soft rubber-like materials. However, this method has the following disadvantages: 1. The material is relatively soft, resulting in poor walking comfort. 2. Due to welding stress and other factors, the surface of the open deck is uneven, and the vibration damping pads are also uneven. 3. The vibration damping pads are affected by ambient temperature; they may shrink and develop gaps in winter and expand and bulge in summer. 4. The vibration damping pads adhere to the deck and are not easy to clean. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple structure, high comfort, high flatness, and easy-to-clean method for installing vibration-damping floors on open-air decks of ships.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] An open-air deck for a ship equipped with a vibration-damping floor is characterized by having a hull, a steel deck, and a vibration-damping floor. The steel deck is connected to the vibration-damping floor via a magnetically adjustable bracket. The magnetically adjustable bracket includes a magnetic base, a height adjustment seat, a leveling shim, and a vibration-damping shim. The magnetic base is magnetically attached to the steel deck from below, and a threaded post is integrally connected to the top of the magnetic base. The lower end face of the height adjustment seat has a threaded groove that mates with the threaded post. The distance between the height adjustment seat and the magnetic base is adjusted by rotating the height adjustment seat. The upper end face of the height adjustment seat has a spherical groove, and a leveling shim is placed at the upper end of the spherical groove. The lower end face of the leveling shim has a spherical protrusion that mates with the spherical groove. The spherical protrusion of the leveling shim offsets within the spherical groove of the height adjustment seat to achieve leveling. The vibration-damping shim is placed above the leveling shim, and the vibration-damping floor is laid on top of the vibration-damping shim. The height and levelness of the vibration-damping floor are adjusted via the magnetically adjustable bracket.

[0006] The vibration damping pad of the present invention is provided with a floor fixing component above it. The floor fixing component includes a cross-shaped floor fixing component and a straight base plate fixing component. The cross-shaped floor fixing component includes a cross-shaped fixing plate and a pin. The pin is connected below the intersection of the cross-shaped fixing plate. The straight base plate fixing component includes a straight fixing plate and a pin. The pin is connected below the middle part of the straight fixing plate. The vibration damping pad and the leveling pad are respectively provided with a connecting insertion hole in the middle part. The pins in the cross-shaped floor fixing component and the straight base plate fixing component are inserted into the insertion holes in the vibration damping pad and the leveling pad in sequence to fix the floor fixing component.

[0007] The magnetic base of the present invention is provided with a soft elastic pad at the bottom. The soft elastic pad is connected to the magnetic base. The soft elastic pad prevents the magnetic base from colliding with the steel deck during movement and adsorption, which would cause paint damage.

[0008] The magnetic base of the present invention is provided with sinking holes on all four sides, and the height adjustment seat is provided with upper sinking holes on all four sides. An upper wrench and a lower wrench are inserted into the upper and lower sinking holes respectively. The height between the magnetic base and the height adjustment seat is adjusted by rotating the upper and lower wrenches in a staggered manner.

[0009] The vibration isolation pad described in this invention is an elastic rubber pad with a thickness of 0.5-1cm, which achieves the effect of vibration reduction.

[0010] The vibration isolation floor described in this invention uses a rigid floor, which can increase the comfort and aesthetics of open-air areas.

[0011] The contact surface between the spherical groove on the upper end face of the height adjustment seat and the spherical protrusion on the lower end face of the leveling shim is set as a knurled rough surface, and the spherical protrusion cannot slide freely in the spherical groove.

[0012] The leveling pad described in this invention is made of magnetic material. After leveling, the magnetic leveling pad can be attracted by the magnetic base, thereby increasing the stability of the leveling pad.

[0013] The vibration damping pad and leveling pad of the present invention are provided with a flared insertion hole with a large lower opening and a small upper opening in the middle. The insertion hole is provided with a countersunk bolt. The leveling pad is provided with a bolt locking hole on the height adjustment seat below it. The bolt locking hole is not smaller than the lower opening diameter of the flared insertion hole and communicates with the threaded groove. The height adjustment seat below the bolt locking hole is provided with a locking nut. The countersunk bolt passes through the insertion hole and the bolt locking hole in sequence and is locked with the locking nut. The threaded groove is provided with a limiting groove above it to prevent the locking nut from rotating.

[0014] The cross-shaped floor fixing component of the present invention includes a countersunk bolt and a cross-shaped fixing plate, and the straight base plate fixing component includes a countersunk bolt and a straight fixing plate. The cross-shaped fixing plate and the straight fixing plate are provided with a locking groove in the middle. The bottom of the locking groove is provided with a bolt through hole. The countersunk bolt is inserted into the vibration isolation pad, the leveling pad and the height adjustment seat through the bolt through hole.

[0016] (1). Design and arrange the installation position of the magnetic adjustable bracket: First, design the number and arrangement position of the magnetic adjustable bracket according to the layout drawing of the vibration isolation base plate. Then, install the magnetic adjustable bracket on the steel deck of the hull. The magnetic base in the magnetic adjustable bracket is attracted to the corresponding position of the steel deck. Then, adjust the height of the magnetic adjustable bracket according to the plane of the steel deck and the corresponding position on the steel deck. Adjust the level of the vibration isolation pad according to the tilt angle of the vibration isolation base plate above the steel deck.

[0017] (2). Laying vibration isolation floor: The vibration isolation floor is laid on the magnetic adjustable bracket for adjusting the height and level. The connection between adjacent vibration isolation floors is fixed by cross-shaped floor fixing parts and straight base plate fixing parts. The lower middle part of the vibration isolation floor is directly supported and fixed by the magnetic adjustable bracket.

[0018] The specific method for adjusting the level of the vibration isolation pads according to the inclination angle of the vibration isolation base plate above the steel deck in step (1) of the present invention is as follows: The vibration isolation pads and leveling pads used have continuous horn-shaped insertion holes with a large lower opening and a small upper opening in the middle. The insertion holes are equipped with countersunk bolts. The leveling pads are provided with bolt locking holes on the height adjustment seat below them, which are not smaller than the lower opening diameter of the horn-shaped insertion holes and are connected to the threaded groove. The height adjustment seat below the bolt locking holes is provided with locking nuts. The countersunk bolts pass through the insertion holes and bolt locking holes in sequence and are locked to the locking nuts. The threaded grooves are provided with limiting grooves to prevent the locking nuts from rotating. During the installation process, the countersunk bolts can be initially adjusted. The bolt and the locking nut are initially connected. After the angle is adjusted, the countersunk bolt is rotated to lock and fix it. The structure of the cross-shaped floor fixing component and the straight base plate fixing component used in step (2) is as follows: the cross-shaped floor fixing component includes a countersunk bolt and a cross-shaped fixing plate, and the straight base plate fixing component includes a countersunk bolt and a straight fixing plate. The cross-shaped fixing plate and the straight fixing plate are provided with a locking groove in the middle. The bottom of the locking groove is provided with a bolt through hole.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] As shown in the attached figure, a ship's open deck with a vibration-damping floor includes a hull, a steel deck 1, and a vibration-damping floor 2. The steel deck 1 is connected to the vibration-damping floor 2 via a magnetically adjustable bracket 3. The magnetically adjustable bracket 3 includes a magnetic base 4, a height adjustment seat 5, a leveling pad 6, and a vibration-damping pad 7. The magnetic base 4 is magnetically attached to the steel deck 1 from below, and a threaded post 8 is integrally connected to the top of the magnetic base 4. The lower end face of the height adjustment seat 5 has a threaded groove 9 that mates with the threaded post 8. The height adjustment seat 5 rotates... The height adjustment base 5 and the magnetic base 4 are adjusted to achieve the distance between them. The upper surface of the height adjustment base 5 is provided with a spherical groove 10. The upper end of the spherical groove 10 is provided with a leveling shim 6. The lower end of the leveling shim 6 is provided with a spherical protrusion 11 that cooperates with the spherical groove 10. The spherical protrusion 11 of the leveling shim 6 is offset within the spherical groove 10 of the height adjustment base 5 to achieve the leveling function. A vibration isolation shim 7 is placed above the leveling shim 6. A vibration isolation floor 2 is laid on the upper end of the vibration isolation shim 7. The height and level of the vibration isolation floor 2 can be adjusted by a magnetic adjustable bracket.

[0033] To ensure the stability of the connection between the vibration isolation floor 2 and the magnetic adjustable bracket, a floor fixing component is provided above the vibration isolation pad 7. The floor fixing component includes a cross-shaped floor fixing component and a straight base plate fixing component. The cross-shaped floor fixing component includes a cross-shaped fixing plate 12 and a pin 13. The pin 13 is connected below the intersection of the cross-shaped fixing plate 12. The straight base plate fixing component includes a straight fixing plate 14 and a pin 13. The pin 13 is connected below the middle part of the straight fixing plate 14. The vibration isolation pad 7 and the leveling pad 6 are respectively provided with interconnected insertion holes 15 in their middle parts. The pins 13 in the cross-shaped floor fixing component and the straight base plate fixing component are inserted into the insertion holes 15 in the vibration isolation pad 7 and the leveling pad 6 in sequence to fix the floor fixing component.

[0034] To ensure the stability of the height adjustment seat 5 and the leveling shim 6 after leveling, a flared insertion hole 15 with a large lower opening and a small upper opening is provided in the middle of the vibration isolation shim 7 and the leveling shim 6. The insertion hole of the vibration isolation shim 7 can be a straight hole, while the insertion hole of the leveling shim is flared. The insertion hole is equipped with a countersunk bolt 19. The height adjustment seat 5 below the leveling shim 6 is provided with a bolt locking hole 20 that is not smaller than the lower opening diameter of the flared insertion hole and communicates with the threaded groove 9. A locking nut 21 is provided in the height adjustment seat 5 below the bolt locking hole 20. The countersunk bolt 19 passes through the insertion hole and the bolt locking hole 20 in sequence and is locked to the locking nut 21. A limiting groove 24 is provided above the threaded groove 9 to prevent the locking nut 21 from rotating.

[0035] The above solution does not use floor fixing components. The vibration isolation pad 7 is equipped with a bolt head storage groove. After the countersunk bolt 19 is locked, it can be stored in the bolt head storage groove to ensure the flatness of the top of the vibration isolation pad 7. The maximum angle of tilt of the countersunk bolt 19 inserted into the above-mentioned funnel-shaped hole from the vertical state is 5 degrees, which can meet the tilt requirements of the ship deck.

[0036] To ensure the stability of the connection between the floor fixing components and the leveling shims 6 and height adjustment seats 5 after leveling, the floor fixing components 7 include cross-shaped floor fixing components and straight-line base plate fixing components. The cross-shaped floor fixing components include countersunk bolts 19 and cross-shaped fixing plates 12, and the straight-line base plate fixing components include countersunk bolts 19 and straight-line fixing plates 14. The cross-shaped fixing plates 12 and straight-line fixing plates 14 are provided with locking grooves 23 in the middle. The bottom of the locking grooves 23 is provided with bolt through holes 22. The countersunk bolts 19 are inserted into the vibration damping shims 7, leveling shims 6 and height adjustment seats 5 through the bolt through holes 22. Elastic rubber sealing posts are inserted into the locking grooves 23 to seal them.

[0037] Furthermore, a soft elastic pad 16 is provided below the magnetic base 4. The soft elastic pad 16 is connected to the magnetic base 4. The soft elastic pad 16 prevents the magnetic base 4 from colliding with the steel deck 1 during movement and adsorption, which would cause paint damage.

[0038] Furthermore, the magnetic base 4 is provided with sinking holes 17 around its perimeter, and the height adjustment seat 5 is provided with upper sinking holes 18 around its perimeter. An upper wrench and a lower wrench are inserted into the upper sinking holes 18 and the sinking holes 17 respectively, and the height between the magnetic base 4 and the height adjustment seat 5 is adjusted by rotating the upper wrench and the lower wrench in a staggered manner.

[0039] Furthermore, the vibration isolation pad 7 is an elastic rubber pad with a thickness of 0.5-1cm, which achieves the effect of vibration reduction.

[0040] Furthermore, the vibration isolation floor 2 is made of hard flooring, which can increase the comfort and aesthetics of the open-air area.

[0041] Furthermore, the contact surface between the spherical groove 10 on the upper end face of the height adjustment seat 5 and the spherical protrusion 11 on the lower end face of the leveling pad 6 is set as a knurled rough surface, and the spherical protrusion 11 cannot slide freely within the spherical groove 10.

[0042] Furthermore, the leveling pad 6 is made of magnetic material. After being leveled by the magnetic leveling pad 6, it can be attracted by the magnetic base 4, thereby increasing the stability of the leveling pad 6.

[0043] A method for laying vibration isolation floor 2 on the open deck of a ship, characterized by the following laying steps:

[0044] (1). Design and arrange the installation position of the magnetic adjustable bracket 3: First, according to the layout diagram of the vibration isolation base plate, design the number and arrangement position of the magnetic adjustable bracket 3. Then, install the magnetic adjustable bracket 3 on the steel deck 1 of the hull. The magnetic base 4 in the magnetic adjustable bracket 3 is attracted to the corresponding position of the steel deck 1. Then, adjust the height of the magnetic adjustable bracket 3 according to the plane of the steel deck 1 and the corresponding position on the steel deck 1. Adjust the level of the vibration isolation pad 7 according to the tilt angle of the vibration isolation base plate above the steel deck 1.

[0045] (2). Laying vibration isolation floor 2: The vibration isolation floor 2 is laid on the magnetic adjustable bracket 3 for adjusting height and level. The connection between adjacent vibration isolation floor 2 is fixed by cross-shaped floor fixing parts and straight base plate fixing parts. The lower middle part of the vibration isolation floor 2 is directly supported and fixed by the magnetic adjustable bracket 3.

[0046] Furthermore, the specific method for adjusting the level of the vibration isolation pad 7 according to the inclination angle of the vibration isolation base plate above the steel deck in step (1) is as follows: the vibration isolation pad 7 and the leveling pad 6 are continuous funnel-shaped insertion holes with a large lower opening and a small upper opening in the middle. The insertion holes are equipped with countersunk bolts 19. The leveling pad 6 is provided with a bolt locking hole 20 connected to the threaded groove 9 on the height adjustment seat 5 below it. The bolt locking hole 20 is not smaller than the lower opening diameter of the funnel-shaped insertion hole. The height adjustment seat 5 below the bolt locking hole 20 is provided with a locking nut 21. The countersunk bolt 19 passes through the bolt through hole 22, the insertion hole, and the bolt locking hole 20 in sequence and is locked to the locking nut 21. The threaded groove 9 is provided with a limiting groove 24 above it to prevent the locking nut 21 from rotating. During the installation process, the countersunk bolt can be initially adjusted. The bolt 19 is initially connected to the locking nut 21. After the angle is adjusted, the countersunk bolt 19 is rotated to lock and fix it. The structure of the cross-shaped floor fixing component and the straight base plate fixing component used in step (2) is as follows: the cross-shaped floor fixing component includes the countersunk bolt 19 and the cross-shaped fixing plate 12, and the straight base plate fixing component includes the countersunk bolt 19 and the straight fixing plate 14. The cross-shaped fixing plate 12 and the straight fixing plate 14 are provided with a locking groove 23 in the middle. The bottom of the locking groove 23 is provided with a bolt through hole 22. The countersunk bolt 19 is inserted into the vibration isolation pad 7, the leveling pad 6 and the height adjustment seat 5 through the bolt through hole 22. During the installation process, the countersunk bolt 19 can be initially connected to the locking nut 21. After the angle is adjusted, the countersunk bolt 19 is rotated to lock and fix it.

[0047] The aforementioned magnetically adjustable bracket 3 has vibration damping and sound insulation functions, allowing the replacement of soft rubber sound insulation pads with hard flooring or specially designed flooring (such as perforated flooring) without concern for floor vibration and noise. This increases the comfort and aesthetics of the open-air area floor. Depending on the surface condition of the open deck, the height of individual support points can be adjusted using the magnetically adjustable bracket 3. The level of individual points can be adjusted based on local levelness to ultimately ensure the overall flatness of the vibration-damping floor 2. Since the floor is at a certain height from the ground, if it is a hard, enclosed floor, cleaning underneath the floor is not a concern; if it is a perforated floor, the deck can be cleaned using high-pressure air or water without removing the floor.

[0048] The magnetic base 4 in the magnetic adjustable bracket 3 of this invention is magnetic and can be adsorbed onto the open steel deck 1 without welding. It is easy to move. The bottom of the magnetic base 4 is provided with a soft elastic pad 16, which is made of rubber. This prevents the magnetic base 4 from rigidly colliding with the deck during adsorption and movement, which could damage the paint. It also has a certain vibration isolation effect. At the same time, the vibration isolation pad 7 is also made of elastic rubber, which can play a good role in vibration reduction.
