Abstract

PURPOSE:To obtain strength and a secondary moment of inertia higher than those of honeycomb structure by a sheet of a plate, by a method wherein processing such as bending. curving of a plate is perfomed by a die roll, corner parts are deformed into acute angles, different positions of the plates are brought into contact directly with each other or indirectly with each other by pinching the plate and a two-dimensional closed space is formed. CONSTITUTION:A sheet of plate is bent or deep-drawn, a continuous primary molded boby is made and plastic deformation is imparted further to its nook part or corner part 1 respectively by a processing jig 6 such as a roll or a die so that the nook part or the corner part 1 becomes an acute angle. On the one hand, plastic deformation is imparted to neither a top plate 3 nor a bottom plate 4 and bend processing is performed at the larger radius of curvature so as to be limited to elastic deformation. When the processing jig is removed after that, the nook part or the corner part 1 keeps an imparted form of the acute angle given by plastic deformation, the top plate 3 and bottom plate 4 are spling-backed horizontally and becomed a three- dimensional body. The three-dimensional structural body whose strength in a longitudional direction is extremely high and weight is small is obtained by two stage processing through the sheet of the plate like this.

The present invention relates to structural materials such as walls, ceilings, roofs and doors, lightweight and high-strength structural materials such as simple bridges, scaffolding boards and concrete formwork, and high-strength and lightweight vibration damping materials and sound insulation materials.

2. Description of the Related Art A honeycomb structure is known as a conventional high-strength and lightweight structural material, but it is expensive because of a complicated manufacturing method and its application is limited to aircrafts. Also, keystone plates, shaped steel, other lightweight shaped steels, or bonded timbers are used for construction. Recently, it has been practiced to make honeycomb structure materials from light metals such as aluminum and titanium.

[0003]

In the conventional honeycomb structure, a honeycomb-shaped plate is sandwiched and adhered between two plates. Its strength depends on the strength of the honeycomb board and the adhesive, and it cannot beat the strength of the upper and lower boards themselves, and the manufacturing method is complicated and the cost is high. Also, the keystone plate itself cannot be used as it is because the surface is uneven, so it is necessary to cover the top or bottom with another plate. It is an object of the present invention to inexpensively manufacture a three-dimensional structure which has a strength and a second moment of inertia higher than that of a honeycomb structure by elastically forming one plate and can be used alone. This method also aims to manufacture a three-dimensional structure having a complicated curved surface shape.

[0004]

[Means for Solving the Problems] One plate is bent or deep-drawn by a roll or a press, and FIG.
A continuous primary molded body as shown in is made. The corners or corners (1, 2) of this primary molded body are further plastically deformed by a processing jig (6) such as a roll or a die shown in FIG. The top plate (3) and the bottom plate (4) in the horizontal portion are bent with a large radius of curvature compared to the plate thickness so that plastic deformation is not given and only elastic deformation is stopped. The thick line in FIG. 2 shows the sectional shape of the plate at the end of processing. After that, when the processing jig is removed, the corners or corners (1, 2) maintain the plastically deformed acute angle shape,
Since the top plate (3) and the bottom plate (4) in the horizontal portion are not plastically deformed, the three-dimensional structure as shown in FIG. 3 is formed by elastically recovering to the original horizontal state or by springing back. In this way, a three-dimensional structure is completed from one plate in two steps, and a structural body having a very large strength in the longitudinal direction and a light weight can be obtained. Of course, one plate may be processed as it is in one step using the processing jig (6). Further, as shown in FIG. 3, by continuously adhering (7) or partially adhering (8) the joints of the plates by welding or the like, the strength in both the vertical and horizontal directions can be increased.

On the other hand, bending or deep drawing is carried out by a roll or a press to form a continuous primary compact as shown in FIG. This primary molded body has been plastically deformed so that the entire corners thereof have already become acute angles, and the top plate (3)
Also, a part of the bottom plate (4) is bent and plastically worked. Only the bent top plate (3) and bottom plate (4) are re-plasticized and flattened using a processing jig (9) such as a roll or a die shown in FIG. 5, and one corner (1, 2) and the side plate (5) are elastically deformed so as not to hit the processing jig (9) strongly. Then processing jig (9)
When removed, the top plate (3) and the bottom plate (4) are plastically worked and returned to the original horizontal state, and the corners (corners) (1, 2) and the side plates (5) are elastically restored, that is, spring back. As a result, the acute-angled shape is maintained, so that a three-dimensional structure as shown in FIG. 3 is formed. Contrary to the difficulty of suppressing springback in the usual plastic working method, the present invention leaves a portion for elastic recovery positively, and combines elastic deformation utilizing springback and plastic working. This is a unique processing method that should also be called an elasto-plastic processing method.

Instead of the processing jig (9) shown in FIG. 5, a processing jig (10) shown in FIG. 6, for example, is used to form ribs (11) on the top plate (3) and the bottom plate (4) in the longitudinal direction. Is provided, a three-dimensional structure as shown in FIG. 7 is obtained. FIG. 4 (b). The continuous primary molded body shown in (c) is processed into a processing jig (12). When the top plate (3) and the bottom plate (4) are plastically processed using (13), a highly rigid three-dimensional structure as shown in FIG. 9 can be formed. Further, by providing ribs (14) in the lateral direction or the diagonal direction on the top plate (3) and the bottom plate (4), a highly rigid three-dimensional structure as shown in FIG. 10 can be formed. As described above, the ribs (11) are formed on the top plate (3) or the bottom plate (4). By providing (14), the rigidity of the top plate (3) and the bottom plate (4) is increased, and the dent resistance is improved, so a thin plate can be used, which is effective in reducing the weight, and also in the effect of patterning and non-slip. Also occurs.
When the side plate (5) is processed so as to have reinforcing ribs (15) as shown in FIG. 11 in the bending, the primary forming process of the drawing, or the final elasto-plastic working process, this increases the rigidity of the side plate (5). It is possible to make a three-dimensional structure that is highly resistant to buckling. Reinforcing ribs (11) provided on the top plate (3), the bottom plate (4) and the side plate (5). (14). The plate between (15) is pre-punched and partially cut by mechanical cutting, etc., and the window (1
Further weight reduction can be achieved by shaping 6). When the ribs (15) are processed so as to reach the top plate (3) and the bottom plate (4), the adjacent top plates (3) and the adjacent bottom plates (4) mesh with each other as shown in FIG. As a result, the plates can be prevented from shifting and a high-strength three-dimensional structure can be obtained without welding.

According to this method, a three-dimensional structure having a width of approximately 1/4 of the original plate can be formed as it is. However, when the primary molded body is manufactured, both the top plate (3) and the bottom plate (4) are pressed to deep draw. When processed, the side plate (5) becomes thin and lightweight, and at the same time, the three-dimensional structure having a width of about half the original plate can be manufactured without reducing the width of the three-dimensional structure. Reinforcing ribs (15) for deep drawing on the thinned side plate (5)
By molding, the rigidity can be supplemented. In this case, since the thicknesses of the top plate (3) and the bottom plate (4) are maintained, an ideal three-dimensional structure having a large second moment of area is obtained. Also, either one of the top plate (3) and the bottom plate (4), for example,
When deep drawing is performed with only the top plate (3) constrained, both the bottom plate (4) and the side plates (5) become thin, and the top plate (3) side has a strong three-dimensional structure in which the second moment axis of the cross section is biased and wide. Can be created. Since the top plate (3) is strong against buckling and dents, it can be used as a floor plate. Since the metal that can be deep-drawn is a soft metal, rigidity and strength can be increased at the same time when heat treatment is applied after molding the primary molded body or after molding the three-dimensional structure. In the case of iron / steel, a light-weight three-dimensional structure having a large hardness, strength, and rigidity can be produced by adding heat treatment such as carburizing, nitrogen-immersing, bake hardening, and quenching to other materials.

[0008]

When a load is applied to the three-dimensional structure just molded in this way from above, the forces are laterally distributed and the triangular prism-shaped three-dimensional elements are pressed against each other to compete as shown by the arrow in FIG. , Even if the seams are not joined, a strong structure is formed by itself. Further, the seam portions of the top plate (3) and the bottom plate (4) of the three-dimensional structure shown in FIGS. 3, 7, 9, 10, and 12 are welded, attached, soldered, pressed,
A stronger solid structure can be obtained by joining with forging, diffusion joining, gluing, adhesive, fitting, bolts, clamps, jigs and the like. One example is shown in FIG. All the joints may be joined together, or the joints may be partially joined together by spot welding or the like to sufficiently increase the strength. The weld beads also serve as a non-slip or design. By doing so, the rigidity increases in the two-dimensional direction, so when it is used as a constituent material for floors, ceilings, walls, roofs, and doors, the beams of buildings can be simplified, and of course the shape can be maintained during transportation. It is convenient.

For example, the second moment of area, which represents the vertical bending rigidity, will be compared with a U-shaped keystone plate. Here, as shown in FIG. 14, a height of 5 cm,
The thickness of the plate is 1.6 mm, one span is 20.08 cm, and the second moment of area per one span of the keystone plate having a cross-sectional area of the material for one span of 4.76 cm ² is 21.85 cm ⁴ Becomes Therefore 1
The second moment of area per cm width is 21.85 cm ^4.
/20.08 cm = 1.09 cm ⁴ , the cross-sectional area per 1 cm width, that is, the value corresponding to the amount of material used is 4.76 cm
It is a ^{2 /20.08cm=0.24 2.} On the other hand, the height of the regular triangular cross-section shown in FIG. 3 is 5 cm, the thickness of the top plate (3) and the bottom plate (4) is 0.8 mm, and the thickness of the side plate (5) is 0.35 m.
m, 1 span 5.77 cm, 1 second span material cross-sectional area 1.31 cm ² The geometrical moment of inertia per span of this three-dimensional structure is calculated to be 6.34 cm 2.
It becomes ⁴ . Therefore, the second moment of area per 1 cm width is 6.34 cm ⁴ /5.77 cm = 1.10 c
m ⁴ , cross-sectional area per 1 cm width, that is, a value corresponding to the amount of material used is 1.31 cm ² /5.77 cm = 0.23 cm
It is ² . Table 1 shows them in comparison with each other in an easy-to-understand manner. From the above results, it can be seen that a three-dimensional structure having a second moment of area comparable to the keystone plate can be formed by using the same amount of material per occupied area. Since the surface of the keystone plate is uneven, it is necessary to further lay one plate or concrete on the surface, and the rigidity of the keystone plate against torsion is very small. However, the surface of this three-dimensional structure is already flat, and when the seams are welded, this alone has a high rigidity in the three-dimensional direction and a high rigidity against torsion.

[Table 1]

As shown in FIG. 15, when a sound absorbing material such as rubber, plastics or wood or a vibration damping material (17) is sandwiched between the joints or in the recessed space, a vibration damping three-dimensional structure is formed. At this time, the joints are joined so as to partially cross the bridge, or the side plate (5) and the sound absorbing or damping material (1
When 7) is adhered, a vibration-damping three-dimensional structure having high rigidity is formed. Further, as shown in FIG. 16, an interposing material (1
By designing so as to sandwich 8), the width of the present three-dimensional structure can be expanded. By joining the joints of the interposing members (18) by welding or the like, it is possible to form a wide three-dimensional structure having high rigidity like the above-mentioned structure. FIG. 17 shows an example of a sound insulation wall in which a sound absorbing material or a vibration damping material (17) is sandwiched between seams and holes are formed in a molded body, and a sound absorbing material is lined inside. It is effective as a vibration damping and sound absorbing wall with strength on highways, bullet trains, railways, airports, factories, etc.

[0012]

[Embodiment] When the above-mentioned three-dimensional structure is used for a floor of a building, the floor can be freely designed by combining it with a beam (19) of H-section steel, T-section steel, C-section steel, etc. as shown in FIG. It was found that not only was the weight reduced, but also the wiring could be routed vertically and horizontally by utilizing the window (16), which is also optimal as a floor structure for an OA office. The present invention is also characterized in that a long-span three-dimensional structure can be produced by roll-forming a coil plate.For example, a roof of a large-area gymnasium, a roof stadium, a warehouse, an exhibition hall, etc. It can be made without columns. In a larger span structure, a large tensile stress acts on the bottom plate (4) due to the load and its own weight. Therefore, as shown in FIG. 19, a reinforcing bar parallel to the inner bottom surface of the three-dimensional structure or its outer bottom surface,
A stringer (20) made of a reinforcing wire, a metal wire, a shaped steel, a high-strength synthetic resin wire, various fibers, and other fasteners may be stretched and tightened from both ends to form a so-called PS (Pre-Stressed) structure. As shown in FIGS. 20 (a) and 20 (b), a primary molded body in which the width of the top plate (3) is wider than the width of the bottom plate (4) is made, and the same elasto-plastic processing is applied, as shown in FIG. A strong cylindrical structure can be formed. Further, when a primary molded body in which the length of the top plate (3) is made longer than the length of the bottom plate (4) is made and processed in the same manner, the conventional corrugated sheet like the supporting steel, the tunnel inner wall water blocking plate and the snow shelter shown in FIG. It is possible to make an arched structure that replaces the. This structure can be easily made by processing with different upper and lower peripheral speed rolls, especially at the time of making the primary formed body and the elasto-plastic processing.

If a primary molded body including a curved surface is formed by plastic working with a roll, a press or the like and then elasto-plastic working is applied, a solid three-dimensional structure having a complicated shape as shown in FIGS. 22 and 23 can also be formed. . FIG. 23B shows a structure in which the liner is lined and welded to increase the rigidity. For example, when the three-dimensional structure shown in FIG. 22 is used as a monocoque body in which the strength frame and the outer shell of a passenger car are integrated, the torsional rigidity is very large, the car body becomes light, and energy saving and high safety passenger car could be designed. Similarly, the technique of complex curved surface molding shown in FIGS. 22 and 23 can be applied to the production of a strength member along the shape of a door, such as a side door impact beam of a passenger car, and a sound absorbing material or a vibration damping material ( 1
It can also be used as a quiet door or outer shell structure by inserting 7). When used in a box-type structure, the frame and outer wall can be integrated, resulting in a great effect. When these three-dimensional structures are used as the structure of transportation equipment such as railway vehicles, large land vehicles, aircraft, ships, etc., the strength and rigidity are higher than the honeycomb structure, the safety is high and the weight is low, and the large internal volume can be obtained at a low cost. An outer shell is created. When a sound absorbing material or a vibration damping material (17) is sandwiched or adhered thereto as shown in FIGS. 15 and 17, an outer shell structure with less vibration is produced, which is quiet.

From the primary molding of FIG. 24 (a) to FIG.
A two-layer three-dimensional structure shown in (b) is formed. It can be used for heat exchangers, heat insulating structures, etc. as well as for high strength structures. A roof tile, a wall, or a non-slip floor plate-like object shown in FIG. 25 can be manufactured by the same manufacturing method. By sandwiching or adhering a sound absorbing material or a vibration damping material (17) thereto, it is possible to form a roof where rain noise cannot be heard, a floor and a wall where vibration noise is small. As shown above, a three-dimensional structure having a cross-section that can be drawn with a single stroke can be manufactured based on the present technology. As for the slope or wall or roof shape shown in FIG. 26 (a), for example, the top plate (3) shown in FIGS. 26 (b) and (c) is elasto-plastically processed into a primary molded body which is slightly wider than the bottom plate (4). It can be made by doing. Further, the staircase structure of FIG. 27A can be manufactured all at once by subjecting the primary molded body of FIGS. 27B and 27C to elasto-plastic processing. This also includes sound absorbing material or damping material (1
By sandwiching 7), it can be used as a quiet emergency staircase. As shown in FIG. 28, a three-dimensional structure having a taper (gradient) in the vertical direction or the horizontal direction can be manufactured. In addition, the various three-dimensional structures described above can be used as they are or as a lightweight scaffolding board, simple bridge, and simple paving board by increasing the rigidity by adding an embossed design to the surface. Further, since water can be drained from the joint, it can be used as a concrete formwork or a decorative formwork, and a pattern can be transferred onto the surface of concrete. It can also be used as a durable lightweight pallet that can be handled as it is by a forklift.

[0015]

Since the present invention is constructed as described above, it has the following effects. A lightweight three-dimensional structure is made by elastically processing one plate, and the upper and lower plates (top plate (3) and bottom plate (4)) and the sandwiched plate (side plate (5)) are the same plate. Since it is connected with, the rigidity is high. In the usual honeycomb structure, the upper and lower plates and the sandwiched plate are separately bonded by an adhesive, which is fundamentally different from the fact that the strength of the structure depends on the strength of the adhesive. Instead, in the present technology, both the top plate (3) and the bottom plate (4) are finely divided, and since they are in contact with each other only by the elastic recovery force of the material, the rigidity in the lateral direction is small as it is. However, as shown in Fig. 3, the seams are exposed to the outside, and if they are connected by welding or the like, the strength can be kept the same as that of a single plate and the rigidity in the lateral direction can be increased. A high three-dimensional structure is obtained. In the technique of the present invention, the ribs (15) are attached to the side plate (5) and the thickness is reduced to further increase the second moment of area, and an excellent lightweight solid structure that is lighter and stronger than the honeycomb structure can be formed.

When this lightweight three-dimensional structure is used for the floor, partition wall, ceiling and roof of a building, sufficient strength can be obtained and the number of beams can be greatly reduced. In addition, the sound-insulating effect and the heat-insulating effect were obtained by using the sound absorbing material, the vibration damping material (17), the heat insulating material, etc., and the building was quiet and comfortable.
In this building, it is easy to make room between each floor, and since the inside of this lightweight three-dimensional structure itself is also connected by space, it became a high-tech building where utility ducts, wiring ducts for OA, ducts for air conditioning, etc. can be freely taken. . The dome ceiling with a diameter of 200 m can be made with this lightweight three-dimensional structure without providing columns, and the cost can be reduced. This lightweight three-dimensional structure can also be used as a scaffolding board for construction work, a temporary bridge for rivers, and a temporary pavement board for road construction. Its maximum utility is that it can be easily carried and laid by people. If this lightweight three-dimensional structure is used as a housing, the rigidity and strength will be further increased, so that the skeleton of land, sea, and air transportation equipment can be simplified and the outer shell structure can be made lighter, and therefore the entire structure can be made lighter. To reduce the burden on the vehicle, increase the internal volume and payload, and increase the transportation efficiency to save energy and improve safety.
Greatly effective in cost reduction.
