Description

Board with built-in member, insulation structure and vessel for preventing flooding

The present invention relates to a board having a built-in member, an insulating structure including the same, and a vessel for preventing immersion, and more particularly, a board configured to be lightweight, excellent in heat insulation and insulation, and excellent in impact resistance and flexural rigidity. It relates to a structure and a ship for preventing flooding.

A board is a structural element used to divide and enclose a space, and is a hard and wide plate as an auxiliary material used as a roof, floor, inner or outer wall, partition wall, or bearing member of a building or a work.

The types of boards include boards in which various insulation materials or soundproof and heat-insulating materials are combined with metal plates such as aluminum composite boards and aluminum sheet boards, and asbestos boards such as enamel boards, honeycomb boards, ceramic boards, carrier boards, and stainless boards. , Polypropylene, polyethylene, polyester, expandable polystyrene, expandable polypropylene, expandable polyethylene in materials such as glass, cement, ceramic, and wood There is a board with synthetic resin such as

The conventional boards are made of iron plate, ceramic, wood, etc. as a main component material, so that the weight of the board itself is heavy, making transportation difficult, and the manufacturing process is difficult, which increases the construction cost due to the increased production cost.

In addition, in the case of boards in which synthetic resins are bonded together, spray type bonds containing toxic chemicals such as toluene are used for adhesion to the metal plate, which is not only harmful to workers but also used once after manufacture. The product has the disadvantage that it cannot be used again.

On the other hand, as mentioned above, in the case of a board manufactured to be filled with one kind of material, even if it is made of synthetic resin, it is difficult to carry out the manufacturing and manufacturing process due to its large weight to volume, and a large buoyancy such as a ship. For this required product there is a limit to use, there is a disadvantage that it is vulnerable to insulation and sound insulation. In addition, the board manufactured to be filled inside has a disadvantage in that the ability to completely cushion the external shocks is very low and is easily broken by external shocks.

In order to solve such a problem, a board having a double structure has been proposed to have an empty space therein, but the proposed double board has a problem in that flexural rigidity in the thickness direction is very weak.

In addition, as a conventional heat insulating structure such as a cooler box, a container house, a container of a refrigeration truck, an organic foam such as rigid urethane foam or expanded polystyrene, a structure filled with a molded body thereof, and a structure filled with inorganic powder such as perlite Etc. In addition, a metal insulation container configured to form a space formed therein as a vacuum insulation space layer to obtain an effect of improving heat insulation performance, reducing the thickness of the product, and increasing the volume ratio may be used.

However, the method of filling the organic foam inside the structure takes a lot of filling operation time and it is difficult to evenly fill the organic foam throughout the structure, the method of inserting the preformed organic foam molded body into the structure In addition to the difficulty of exactly matching the size and the size of the organic foam molded article, there is a problem that the entire organic foam molded article must be replaced when a part of the organic foam molded body is broken. In addition, the structure in which the inorganic powder is filled in the structure, the weight of the inorganic powder itself is heavy and bad workability, there is a disadvantage that takes a lot of manufacturing time and poor manufacturability. On the other hand, in the case of forming an empty space inside the structure to fill the organic foam or inorganic powder, there is a problem that the phenomenon is easily bent or broken by an external impact.

In addition, the structure in which the vacuum insulation space layer is formed in the structure of the metal material has the advantage that the thermal insulation performance is improved, the volume ratio can be increased by reducing the thickness, and the phenomenon of bending or breaking due to external impact is not easily generated. In addition, the work process for forming a vacuum insulation space layer is very complicated and it is difficult to apply to large products such as containers of container houses and refrigeration tower cars.

On the other hand, interest in marine leisure activities is rapidly increasing thanks to the improvement of quality of life and the 5-day workweek system. Considering the global trend, if the national income is over $ 30,000, leisure patterns change from land leisure activities to marine leisure activities. In Korea, where the three sides are the seas, the development of maritime leisure is expected to take off in the near future. .

Excellent shows merit.

As a result, FRP vessels can be designed and built even lighter while showing sufficient strength, less costly to repair and maintain because they do not rot or corrode. Advantageous features are shown in FIG.

However, due to the nature of the material, FRP has a fatal disadvantage of high vibration resistance, low modulus of elasticity, and greater damage than metal in case of cracks, especially when the hull of a ship is hit by reefs or other offshore structures during operation. Not only is it highly probable, it is also likely to be hull-damaged because it is constantly exposed to large and small impacts, such as constant vibrations or wave collisions, such as slamming or springing. There is a problem directly connected to the damage caused by the. In addition, such a FRP vessel has a problem that even if holes or cracks are formed in the board forming the second plate and the side plate of the hull, water is immediately introduced into the vessel and eventually the entire vessel is flooded.

In order to solve the above-mentioned problems, a method of making a board very thick may also be considered, but in this case, the overall weight of the hull is increased, making it difficult to manufacture and transport as well as fuel consumption, and significantly increase the manufacturing cost. It has the disadvantage of being.

On the other hand, FRP is due to the discharge of environmental pollutants in the manufacturing process, the situation is a light and durable marine materials that can replace the FRP in the recent situation is emerging.

Board according to the present invention, the first plate 100 and the second plate 200 arranged in parallel to be spaced apart from each other, the interior is inserted and mounted between the first plate 100 and the second plate 200 By pressing the first plate 100 and the second plate 200 toward the interior member 300 to maintain a constant distance between the member 300 and the first plate 100 and the second plate 200. It is configured to include a pressing member 400 for coupling.

At this time, the interior member 300 is applied to a foamed resin having a gas layer (more specifically, an air layer) therein to be elastic, or a gas capsule sealed by injecting gas into the interior, and thus inside the interior member 300. Since the provided gas layer is superior in heat insulation and sound insulation compared to solid layers such as the first plate 100 and the second plate 200, the heat insulation and sound insulation of the entire board are significantly increased. In addition, if the built-in member 300 having a gas layer, such as a board according to the present invention is provided therein, the weight compared to the volume is reduced, there is an advantage that the portability and workability is also improved.

On the other hand, the edge coupling member 500 is mounted on the edges of the first plate 100 and the second plate 200 so that the space between the first plate 100 and the second plate 200 is isolated from the outside. This is preferable. In the present embodiment, only the structure in which the edge coupling member 500 is formed in a '-' beam shape and the edges of the first plate 100 and the second plate 200 are inserted into the edge coupling member 500. Although shown, if the space between the first plate 100 and the second plate 200 can be isolated from the outside the shape of the edge coupling member 500 may be variously changed. For example, the frame coupling member 500 may be changed in shape so as to be inserted between the edges of the first plate 100 and the second plate 200.

On the other hand, in order to bend the board according to the present invention, the radius of curvature of the first plate 100, the radius of curvature of the interior member 300 and the radius of curvature of the second plate 200 should be different, in this case, the first plate As long as the 100, the interior member 300, and the second plate 200 do not extend or contract, a sliding phenomenon occurs between the first plate 100 and the interior member 300 and the second plate 200. A slip phenomenon occurs between the interior member 300. However, when the interior member 300 is pressed between the first plate 100 and the second plate 200 by the pressing force of the pressing member 400, as described above, the first plate 100 and the second plate 200 has an advantage that the friction force with the built-in member 300 is very large so that it is not easily bent or twisted. At this time, the pressing member 400 is the first plate 100 and the second plate 200 so that the interior member 300 is most effectively compressed between the first plate 100 and the second plate 200. It is preferable to press the first plate 100 and the second plate 200 toward the interior member 300 in the direction perpendicular to the width direction of the).

The pressing member 400 does not merely serve to couple the first plate 100 and the second plate 200 by simply pressing the built-in member 300 to the side, and the first plate 100 and the second plate 200. There is also a feature of configuration in that it also serves to keep the separation distance between) constant. Therefore, the pressing member 400, as mentioned above, the first plate 100 and the first plate 100 and the second plate 200 to maintain a constant distance between the role, so as to play a role, A sleeve 410 mounted between the two plates 200 and having longitudinal ends thereof contacting the first plate 100 and the second plate 200, respectively, and the first plate 100 and the second plate 200. It is configured to include a pair of fastening means 420 for pressing each of the lengthwise ends of the sleeve 410.

As such, the sleeve 410 is inserted between the first plate 100 and the second plate 200 so that the sleeve 410 stands vertically. The gap between the first plate 100 and the second plate 200 is a sleeve ( It is not narrower than the length of 410. In addition, the first plate 100 and the second plate 200 are fixed to the upper and lower ends of the sleeve 410 by fastening means 420, respectively, as long as the fastening means 420 is not damaged. It is not separated from the sleeve 410. That is, the first plate 100 and the second plate 200 are fixed to each other while maintaining a state spaced apart by the length of the sleeve 410. The structure in which the sleeve 410 is coupled to the first plate 100 and the second plate 200 by the fastening means 420 will be described in detail with reference to the accompanying drawings.

Meanwhile, the fastening means 420 for coupling both ends of the sleeve 410 to the first plate 100 and the second plate 200 may be applied as a fastening bolt, but the fastening means 420 is fastened as described above. If the bolt is applied, not only takes a lot of time for the fastening operation but also has the disadvantage that the fastening bolt can be released by external vibration. Therefore, the fastening means 420 is preferably applied to the rivet so that the time required for the fastening operation is small and there is no fear of loosening by external vibration. At this time, the fastening means 420 included in the present invention is not limited to the rivet structure shown in the present embodiment, the both ends of the longitudinal direction of the sleeve 410 is coupled to the first plate 100 and the second plate 200. You can change it to any structure as long as you can. For example, both sides are coupled to the first plate 100 and the second plate 200 to be applied with a fastening wire that pulls the first plate 100 and the second plate 200 toward the monolith 300. It may be.

On the other hand, between the first plate 100 and the second plate 200, as shown in FIG. 1, one large interior member 300 suitable for the size of the first plate 100 and the second plate 200 is It may be provided, as shown in Figures 2 and 3 may be provided with a plurality of built-in member 300 of a small size.

When the built-in member 300 is made large in size to match the sizes of the first plate 100 and the second plate 200, not only the fabrication of the built-in member 300 is facilitated but also the built-in member 300 is manufactured. The cost is reduced, and there is an advantage that the operation of pressing assembly by inserting the internal member 300 between the first plate 100 and the second plate 200 becomes very easy. In addition, when the interior member 300 is made large in one, the contact area between the first plate 100 and the interior member 300 and the contact area between the second plate 200 and the interior member 300 becomes very large. Since the friction force between the first plate 100 and the interior member 300 and the friction force between the second plate 200 and the interior member 300 become very large, the board according to the present invention is not easily bent or twisted. have.

In addition, when the board is bent, the radius of curvature of the first plate 100, the radius of curvature of the internal member 300, and the radius of curvature of the second plate 200 are changed, and thus, the first plate 100 and the first plate 100 are different. The distance between the two plates 200 is different for each part. However, when one large internal member 300 is compressed and filled in the space between the first plate 100 and the second plate 200, the distance between the first plate 100 and the second plate 200 may vary. As it becomes difficult to be very different from each other, as a result, the warpage of the board is not easily generated.

As such, when the interior member 300 is manufactured to be one large to fit the sizes of the first plate 100 and the second plate 200, the sleeve 410 may pass through the interior member 300 to the first plate 100. ) And the second plate 200 will be mounted.

On the other hand, the interior member 300 may be manufactured in a small block shape of a polyhedron or cylindrical may be arranged a plurality of spaced apart a predetermined interval between the first plate 100 and the second plate (200). As such, when the interior member 300 is manufactured in a small block shape and is configured to be mounted in plural, the interior member 300 may be manufactured very easily, and the first plate 100 and the second plate 200 may be Even if the size is changed, the first plate 100 and the second plate may be filled with the interior member 300 by properly adjusting the number of mounting of the interior member 300 between the first plate 100 and the second plate 200. There is an advantage that a separate built-in member 300 is not necessary to fit the size of the 200. In addition, it is possible to easily secure the fastening member 400 fastening space by adjusting the interval between the interior member 300, it is possible to replace only the broken interior member 300 when some of the interior member 300 is broken And an easy maintenance.

At this time, in order to maximize the thermal insulation, sound insulation, impact resistance and the like of the board according to the present invention, it is preferable to minimize the separation gap (G) between the neighboring interior member 300, the two neighboring the pressing member 400 In order to be mounted between the two built-in members 300, a problem arises in that the spacing between the built-in members 300 is larger than the outer diameter D of the sleeve 410. In order to solve this problem, the interior member 300 is arranged at equal intervals in the horizontal and vertical directions and the pressing member 400 is between the four adjacent interior member 300, that is, the four interior member 300 It may be mounted at the location where the corners meet. In this way, if the mounting position of the pressing member 400 is set between the four adjacent inner members 300, even if the two adjacent inner members 300 are spaced apart by a distance smaller than the outer diameter (D) of the sleeve 410 Since the member 400 can be mounted, there is an advantage that the separation distance G between the internal members 300 can be reduced.

Furthermore, in order to further reduce the separation distance between the interior member 300, the interior member 300 has a chamfered surface 310 at the portion where the pressing member 400 (more specifically, the sleeve 410) passes; Can be formed. When the chamfered surface 310 is sufficiently large, the separation distance G between the interior members 300 may be set to '0', that is, the adjacent interior members 300 may be in close contact with each other. In the present embodiment, only the case where the chamfered surface 310 is formed in a planar shape, the chamfered surface 310 may be changed into various shapes such as curved surfaces according to manufacturing convenience or the shape of the pressing member 400. .

In addition, as shown in Figure 3 to form a chamfering surface 310 in each corner of the interior member 300, the outer diameter (D) of the sleeve 410 is made larger than the distance between the two interior interior member 300 If so, each interior member 300 is the result of being fitted between the four sleeves 410 mounted to each chamfering surface (310). Therefore, the inner member 300 may be moved only by the separation distance between the chamfered surface 310 and the sleeve 410 even if the second plate 200 or the first plate 100 is not bonded to each other. As you can not move greatly, the position is limited. In addition, when the chamfered surface 310 and the sleeve 410 of the interior member 300 is in close contact, the interior member 300 may be fixed without shaking at all in the front and rear and left and right directions.

In the case of manufacturing the board according to the present invention, as shown in FIG. 4, the internal member 300 is positioned between the first plate 100 and the second plate 200, and as shown in FIG. 5. Likewise, the sleeve 410 is positioned between the internal members 300. In this case, the sleeve 410 is formed in a hollow pipe shape so that the sleeve 410 can be coupled to the first plate 100 and the second plate 200 by a riveting process. do. Of course, if the rivet can be stably coupled to the sleeve 410, the locking step 412 formed in the sleeve 410 can be omitted. That is, the rivet may be fastened so that one side covers the outer surface of the first plate 100 or the second plate 200 and the other side is pressed against the inner circumferential surface of the sleeve 410.

When the positioning of the sleeve 410 is completed, one end of the fastening means 420 is opened through the through

holes

110 and 210 formed in the first plate 100 and the second plate 200 as shown in FIG. 6. 410 is inserted into. In this case, the fastening means 420 is a rivet fastened to cover the outer surface of the first plate 100 or the second plate 200 and the inner surface of the locking step 412, the cylindrical body portion 422 And an outer head 424 and an inner head 426 provided at both ends of the trunk portion 422 and one end (lower side in this embodiment) on one side (lower side in this embodiment) of the trunk portion 422. It is configured to include a core pin 428 coupled and the other end extending to the outside of the body portion 422. When the insertion of the fastening means 420 is completed, the operator pulls the core pin 428 so that the inner head 426 extends in the horizontal direction and covers and covers the inner surface of the locking step 412. On the other hand, the core pin 428 drawn out of the body portion 422 is removed through a cutting process.

As described above, the sleeve 410 is coupled to the first plate 100 and the second plate 200 by pressing a pair of fastening means 420 to the first plate 100 and the second plate 200, respectively. The two plates 200 are kept spaced apart by the height of the sleeve 410 as long as the sleeve 410 or the fastening means 420 is not damaged.

FIG. 8 illustrates the first plate 100 and the second plate when a downward load is applied to the first plate 100 in a state where the edge portions are coupled so that the first plate 100 and the second plate 200 are spaced apart from each other. As a diagram showing the deformation amount of 200, only the first plate 100 and the second plate 200 are shown for clarity.

When a downward load is applied to the first plate 100 in the state where the edge portions are coupled so that the first plate 100 and the second plate 200 are spaced apart from each other, the first plate 100 and the first plate 100 are shown in FIG. 8. The middle portion of the second plate 200 sags downwards, and since the first plate 100 is directly subjected to force, the amount of sag of the first plate 100 is greater than that of the second plate 200. . That is, the distance between the first plate 100 and the second plate 200 when the load is applied than the interval H1 between the first plate 100 and the second plate 200 when no load is applied. (H2) becomes small.

However, in the board according to the present invention, the sleeve 410 is inserted between the first plate 100 and the second plate 200 so that the distance between the first plate 100 and the second plate 200 is kept constant. As a result, the phenomenon that the deflection amount of the first plate 100 is greater than the deflection amount of the second plate 200 does not occur. That is, since the load applied to the first plate 100 is evenly applied to the second plate 200 through the sleeve 410, the bending strength of the entire board can be improved.

In addition, since the upper and lower surfaces of the interior member 300 inserted between the first plate 100 and the second plate 200 are in close contact with the first plate 100 and the second plate 200, the sleeve 410 is provided. As in FIG. 1, the load applied to the first plate 100 is evenly transmitted to the second plate 200. In this case, when the height of the sleeve 410 is greater than the height of the interior member 300, the top and bottom surfaces of the interior member 300 may not be in close contact with the first plate 100 and the second plate 200. The height of the 410 is preferably set smaller than the height of the built-in member 300.

Meanwhile, in order to prevent the first plate 100 and the second plate 200 from being broken when an external impact is applied, the first plate 100 and the second plate 200 should be made of soft synthetic resin. When the first plate 100 and the second plate 200 are made of soft synthetic resin, there is a problem in that flexural rigidity is lowered and a portion to which impact force is applied is excessively deformed and easily torn. However, if the built-in member 300 and the sleeve 410 is configured to be mounted between the first plate 100 and the second plate 200 as in the board according to the present invention, in order to prevent a cracking phenomenon caused by an external impact. Even when the first plate 100 and the second plate 200 are made of soft synthetic resin, a certain level of flexural rigidity can be obtained, and when the impact force is applied to the first plate 100 and the second plate 200, the interior member Since the first plate 100 and the second plate 200 are not excessively deformed by the elastic force of 300, the first plate 100 and the second plate 200 may be torn. There is an advantage of not being.

When the sleeve 410 provided between the first plate 100 and the second plate 200 is coupled to the first plate 100 and the second plate 200 by the fastening means 420 of the rivet structure, FIG. As shown in FIG. 9, when the first plate 100 is bent by an external force, a portion of the upper surface of the first plate 100 corresponding to the edge of the outer head 424 is pressed upward to the edge of the outer head 424. A portion corresponding to the end of the locking jaw 412 of the bottom of the first plate 100 is pressed downward on the top of the end of the locking jaw 412 (see dotted arrow) to apply a tensile force to the body portion 422. . However, when the body portion 422 of the fastening means 420 is made of a material having high tensile resistance, the first plate 100 is not bent as shown in FIG. 9.

That is, when the sleeve 410 is coupled to the first plate 100 and the second plate 200 by the fastening means 420 of the rivet structure, the bending deformation of the first plate 100 and the second plate 200 is reduced. Since it can prevent more effectively, the effect that the bending strength of the whole board by this invention improves can be acquired.

10 is a cross-sectional view of another embodiment of the pressing member 400 included in the board according to the present invention.

Sleeves 410 included in the pressing member 400 are both the first plate 100 and the second plate 200 by the fastening means 420 at both ends in the longitudinal direction, as shown in the embodiment shown in FIGS. It may be configured to be coupled to the one end in the longitudinal direction is bonded to any one of the first plate 100 and the second plate 200 and the other end in the longitudinal direction by the fastening means 420 It may be configured to be coupled to the other one of the two plates (200).

That is, the pressing member 400 included in the present invention is formed in the shape of a hollow pipe, the lower end of which is joined to the upper surface of the second plate 200 and the other end is in contact with the bottom surface of the first plate 100 410 and a fastening means 420 for pressing-compressing the first plate 100 to the upper end of the sleeve 410.

As such, when one end in the longitudinal direction (the lower end in FIG. 10) of the sleeve 410 is coupled to the second plate 200 in a bonding manner, there is no component protruding to the bottom of the second plate 200. Since the bottom surface of the 200 may be kept smooth, the frictional resistance of the bottom surface of the second plate 200 may be reduced and the appearance may be beautiful.

In this case, as a method of bonding the lengthwise end of the sleeve 410 to the second plate 200, various methods such as a method using a separate adhesive or a method using thermal fusion may be applied.

11 is a cross-sectional view of another embodiment of a built-in member 300 included in the board according to the present invention.

The interior member 300 included in the present invention may be applied to a foamed resin such as a zero board, but when the interior member 300 is applied to the foamed resin, the interior member 300 may be easily wetted with water and the elastic force may be degraded when used for a long time. There are disadvantages. In particular, when the board according to the present invention is used for the purpose of receiving buoyancy, a fatal problem occurs that the buoyancy cannot be received when the internal member 300 is wet with water.

Therefore, the interior member 300 may be applied as a gas capsule sealed by the gas injected therein as shown in FIG. At this time, the gas capsule is preferably made of a synthetic resin that is not wet with water and has a predetermined level or more elasticity.

The gas capsule can maintain elasticity for a long time as long as some part is not torn or damaged, and can be used in water because water does not occur, and the gas content is higher than foamed resin, so the insulation and sound insulation are excellent. Has the advantage.

A sliding phenomenon occurs between the members 300. However, when the interior member 300 is pressed between the first plate 100 and the second plate 200 by the pressing force of the pressing member 400, as described above, the first plate 100 and the second plate 200 has an advantage that the friction force with the built-in member 300 is very large so that it is not easily bent or twisted. At this time, the pressing member 400 is the first plate 100 and the second plate 200 so that the interior member 300 is most effectively compressed between the first plate 100 and the second plate 200. It is preferable to press the first plate 100 and the second plate 200 toward the interior member 300 in the direction perpendicular to the width direction of the).

Since the coupling structure between the first plate 100 and the second plate 200 and the built-in member 300 included in the heat insulating structure is the same as the board structure shown in FIGS. 1 to 11, a detailed description thereof will be omitted.
