Description

  The present invention relates to a lightweight and strong bellows-bonded honeycomb cup that is used as a panel in buildings, ships, vehicles, or arts and crafts, or used as a core material of a panel. The present invention relates to a bellows-bonded honeycomb cup, which is a member having excellent shape retention strength having a wide void layer inside which is formed by bending or molding non-woven fabric, cloth, wood plate, ceramic plate, or the like.

  Existing honeycomb structures are used for various applications because they are lightweight and have excellent compressive strength. In addition, since many existing honeycomb structures have a shape that opens on both sides, it is necessary to fix the surface plate to make the inside closed. That is, there is a drawback that it cannot be used as a panel having a gap when the surface plate is not used.

  In order to eliminate such drawbacks, the following structures have been developed. (See Patent Documents 1 and 2)

JP 2013-52581 A JP 2013-221283 JP

  Patent Document 1 and Patent Document 2 are different from existing honeycomb structures in that they have a recess opening (a recess in which the upper part is open and the lower part is closed) and can be used for a gap without being fixed by a surface plate, and are lightweight and strong. However, in these structures, the gap inside the panel is closed for each part, and it is difficult to fill the material for utilizing the gap. In addition, there is a drawback that it is not possible to effectively use the void layer over the entire panel surface for heat dissipation / heat insulation, soundproofing (sound absorption / sound insulation), and the like.

  The present invention has been developed for the purpose of solving the above drawbacks. An important object of the present invention is to provide a bellows-bonded honeycomb cup that is light in weight and has a compressive strength according to an existing honeycomb structure, and that firmly holds a shape having a wide void layer inside the structure. It is in.

  Another important object of the present invention is to provide a bellows-bonded honeycomb body which can utilize the use of the void layer in combination with the function of each single-sided material. For example, the air gap of the void and the membrane vibration of the surface of the honeycomb cup body are used for sound absorption at the same time, and a sound insulating material is used for the wide bellows band body, and the sound is effectively prevented from both sound absorption and sound insulation. A bellows that heat-insulates the heat source agent on one side of the wide bellows band and uses heat dissipation on one side of the honeycomb cup body. It is to provide a bonded honeycomb cup.

  The honeycomb goblet cell 5 has a hexagonal honeycomb-shaped edge connecting the parallel edge 3 and the chevron edge 4 by connecting the chevron edges 4 in a zigzag manner to the parallel edges 3 arranged in parallel to each other. . It should be noted that two pairs of triangular faces may be omitted from the honeycomb cup-shaped cells located at the left and right side ends, and the supporting surface in that case may be a four-wire edge with the side pieces open. .

  A honeycomb cup body 6 in which the honeycomb cup-shaped cells 5 are joined in a planar shape extends inward from the two parallel edges 3 facing each other in the opening, extends inward from the parallel edges 3, and is inclined downwardly toward the center. The two inclined surfaces 1 are connected, and the bottom line at the center of the two inclined surfaces 1 becomes a parallel edge 3 on the opposite surface. One of the two inclined surfaces 1 constituting the wide bellows inclined surface 7 and the bellows body 1-J between the outer parallel line portion 9 and the inner parallel line portion 8 of the wide bellows band body 10 with the parallel edge 3 at the bottom at the center. The parts are joined to form a bellows joined honeycomb cup 15. In this way, the honeycomb cup body 6 and the wide bellows band body 10 are three-dimensionally joined to form the honeycomb cup body lower void layer 12 having a wide air-permeable void.

  Assuming that the position of the honeycomb cup-shaped cell row 5A is specified, the bellows body 1-J constituting 5A is joined to the wide bellows inclined surface 7 at a fixed position. Two surfaces of the wide bellows inclined surface 7 are joined at a position sandwiching the parallel edge 3 of the bottom line of the two inclined surfaces 1 of the bellows body 1-J of the honeycomb cup-shaped cell row 5A (specific row). The adjacent wide bellows inclined surface 7 having a different inclination direction is joined to the rectangular surface 1X constituting the two inclined surfaces 1 of the type cell row 5C. In this way, the two inclined surfaces 1 are covered and joined one after another with the wide bellows inclined surface 7 having different inclination directions, thereby reducing the compressive deformation in the thickness direction and holding the shape having a wide gap firmly. A bellows-bonded honeycomb cup 15 can be formed.

  FIG. 5 shows the relationship between the structure of the bellows-bonded honeycomb cup 15 and the void layer. The void layer is shown in a side view cut at specific positions (MA and MB, MC and MD, NA and NB, NC and ND) from the upper surface to the lower surface. Honeycomb goblet cell row 5C at a position where the gap layer below bellows body 1-J of honeycomb goblet cell row 5A, the gap layer below cell mountain-shaped edge row 5B, 5A and the cell pitch are shifted by half (SP / 2) The void layer under the bellows body 1-J is shown by the filled portion. The gap layer under the bellows body 1-J of the honeycomb cup type cell row 5A and the honeycomb cup type cell row 5C is the bellows body lower gap layer 12A and the bellows body lower gap layer 12C, but the cell pitch is shifted by half (SP / 2). The space is connected by a triangular lower surface void layer 12B below the inter-cell mountain-shaped edge row 5B, and the voids are connected to form an under bellows body void layer 12.

  In addition, the triangular lower surface void layer 12B indicated by the filled portion under the inter-cell chevron edge row 5B has a change in the shape of the air gap depending on the cutting position (NC, ND in FIG. 5) of the inter-cell chevron edge row 5B. Become.

FIG. 2 shows the relationship between the structure of the bellows-bonded honeycomb cup and the void layer when the honeycomb cup-side support surface 14 and the wide bellows band-side support surface 11 having a certain plate thickness are attached. In the other figures, the wide bellows band side support surface 11 uses a thin material (in the case of FIG. 7, the material is 0.19 mm thick paper), and thus the plate thickness is represented by a line. A perspective view of the bellows-bonded honeycomb cup is shown in the upper part, and a side view of a cross section cut by LA and LB is shown in the lower part. In this example, three void layers are formed: a honeycomb cup in-plane void 5U, a honeycomb cup body void layer 12, and a wide bellows band void layer 13.
The void layer added to the bellows body lower void layer 12 is formed by attaching both or one of the wide bellows band side support surface 11 and the honeycomb cup body side support surface 14, so Both or one of the gap layers 13 can be provided. Moreover, the shape of each void layer can be variously changed by changing the size and shape of the honeycomb goblet cell 5.

  FIG. 6 shows an example of the sound absorption effect of the present invention. This graph shows the results of a normal incidence sound absorption test. The average test results for three samples of each of two types of test samples prepared using paper (thickness: 0.19 mm) and glued with vinyl acetate resin glue. Was graphed. The parallel edge 3 is 10 mm (the length of SW in FIG. 4), the inclined surface is opened at 90 degrees, and the bellows surface vertical length JL (the length between the upper parallel edge 3 and the lower parallel edge 3) is The border edge (2A, 2B) is 20 mm, the panel height is about 15 mm. The height of the panel takes into account a slight change in the size of the paper fold when the specimen is manufactured. The bellows surface vertical length JL is also the vertical length of the rectangular surface 1X.

  FIG. 7 shows the shape of the test product from the top surface with the honeycomb cup body 6 facing up. In the 10 cm circle, the bellows-bonded honeycomb cup body 15 having no support surface is disposed on the honeycomb cup body side. The portion between the outer edge of the circle and the bellows-bonded honeycomb cup was covered with the honeycomb cup-side support surface outer portion 14B. The upper part of FIG. 7 shows a plan view of the test product as viewed from above, the middle part shows a perspective view, and the lower part shows a side view when cut by LM and LN. The honeycomb cup side support surface outer side portion 14B is for mounting on a device for performing a normal incidence sound absorption test. Although the honeycomb cup side support surface inner portion 14A is not attached as a test product, when the honeycomb cup side support surface inner portion 14A is used in another figure (FIG. 2 and the like), it is simply expressed as the honeycomb cup side support surface 14.

  The test product E had the wide bellows band side support surface 11 and had a void layer including a portion under the honeycomb cup side support surface outer side portion 14B. The test product D was filled with a solid material (paper clay) including the portion under the honeycomb cup body side support surface outer portion 14B. E is the side of the honeycomb cup body shown in the lower part of FIG. 6, and the honeycomb cup lower gap layer 12 and the wide bellows band lower gap layer 13 of FIG. 6S remain air layers, and D is the honeycomb cup lower gap layer 12 and the wide bellows. Both of the subband gap layers 13 (hatched areas) are filled with solid matter (paper clay).

  The test product E has a much higher sound absorption performance than the test product D in the low sound range of 200 Hz (Hz) to 800 hertz (Hz), and the sound absorption performance is good in almost the entire sound range. Further, in the case of obtaining the sound absorption performance, the selection of the material constituting the main body of the bellows-bonded honeycomb cup body 15, the change in the structure having the void layer (combination of the dimensions of the bellows-bonded honeycomb cup body 15), and the selection and use of the filler The means can be pursued and the effect can be put out to fit.

  9 and 10 show the comparison results of the compression test in the thickness direction between the bellows-bonded honeycomb cup 15 of the present invention and the honeycomb structure of Patent Document 1. FIG. The test was performed in the same environment (temperature 24.1 degrees, humidity 66%) and under the same conditions (same tester and compression test speed 5 mm / min). The shape and material of the test sample A of the bellows-bonded honeycomb cup 15 and the material of the honeycomb cup test sample H of Patent Document 1 are the same as the test sample H of the honeycomb structure of Patent Document 1, and the material is paper (thickness is 0.25 mm). Created by bonding with vinyl acetate resin glue.

  FIG. 8 shows the shape of the test product viewed from above with the honeycomb cup 6 facing upward, and the test products A, B, and H all have the same shape. The shapes of the test products A and B are such that the parallel edge 3 is 10 mm (the length of SW in FIG. 4), the inclined surface opens at 90 degrees, and the bellows surface length JL (the upper parallel edge 3 and the lower parallel edge) The length between 3) is 20 mm, the boundary edges (3A, 3B) are 16 mm, and the height of the panel is about 15 mm.

  The test sample H of the honeycomb structure of Patent Document 1 has the same honeycomb cup 6 as that of the bellows-bonded honeycomb cup 15 of the present invention on the upper surface, the same shape as the honeycomb cup 6 on the upper surface, and half the cell pitch (SP / 2). Created a staggered version and combined them both up and down. Patent Document 1 introduces several methods for creating a honeycomb structure, but the above-described manufacturing method is selected and a prototype H is prepared.

  FIG. 9 is a graph showing the results of compressive strength tests in the thickness direction of the test article H of the honeycomb structure of Patent Document 1 and the test article A of the bellows-bonded honeycomb cup body 15. In the test product A, neither the wide bellows band body-side support surface 11 nor the honeycomb cup body-side support surface 14 is attached. The test product H is 8.9 g and the test product A is 7.1 g, both of which are about 15 mm in height and 85 mm in length and width.

  The test results show a similar tendency in both cases up to a compressive strength of 0.61 KN (kilonewtons), and both displacements are about 1 mm at 0.61 KN. When the compressive strength is more than that, the displacement of the specimen A increases, and inelastic buckling (breakage causing wrinkles) occurs earlier than the specimen H. However, it can be said that the specimen A has almost the same strength characteristics as the specimen H until the displacement is 1 mm, that is, the height change is 1/15. Although the test product A has a wide void layer and is lightweight, it can be said that the test product A has tough characteristics up to a certain compressive strength.

  FIG. 10 shows a compression in the thickness direction in which a test product B in which wood (cylindrical prisms) of a filled prism 16 is placed in the bellows body lower void layer of the bellows-bonded honeycomb cup body 15 is added to the test product H and the test product A. It is a graph which shows the result of an intensity test. FIG. 12 shows a positional relationship in which the filled prisms 16 are inserted into the gap layer between the honeycomb cup 6 and the wide bellows band 10. The wood used as the filling prism 16 (cylindrical prism) had a width of 10 mm, the same as the parallel edge 3, a square side of 10 mm, and half the length of the inclined surface (20 mm). In this test product, a 10 mm cubic filling prism 16 is formed, and the space between the parallel edge 3 and the wide bellows band 10 is filled without a gap.

  As shown in FIG. 12, the test product B is prepared by first preparing a honeycomb cup 6 with a wood (cypress) prism as a filling prism 16, and then forming the wide bellows band 10 on two surfaces of the filler prism 16. 2 and the inclined surface 1 were bonded to obtain a test product B filled with prisms made of wood (cypress). The weight of the test product B is 14.8 g.

  The result of the compression test is that the test product B is 1.6KN at a displacement of 1 mm and the test products H and A are both 0.61KN, so the strength of the test product B is 2.62 times. It is shown that. The reason is that the strength of the filled prisms 16 is strong and the arrangement position is stable in the bellows-bonded honeycomb cup body 15.

  Wood (hinoki) is used for the filling prism 16 of the test product B. However, this is an example in which a material having moisture conditioning and fragrance diffusing functions is used to enhance the strength as well as exhibit the functions. In the test product B, the filled prisms 16 were filled in all the honeycomb cup-shaped cells.

  Although the test product B used a prism as a material for filling the void layer 12 under the honeycomb cup body, the shape and material to be filled are solid shapes such as vertical plates and pipes so as to be used as products. Products, powder fluids, or liquids that are initially liquid and solidify after insertion, among various combinations such as activated carbon, hygroscopic agent, deodorant, fragrance, mortar, gypsum, clay, sand and other inorganic fillers, wood, etc. You can choose from

  FIG. 13 shows an example in which a wide bellows band 10H sandwiching a flat plate portion is used as a method for further enlarging and utilizing the void layer 12 below the honeycomb cup body of the bellows-bonded honeycomb cup body 15. The bellows-bonded honeycomb cup body 15 is joined to the two inclined surfaces 1 of the honeycomb cup-type cell 5 in the range of the bellows of the wide bellows band to increase the strength, but the wide bellows band body 10H sandwiching the flat plate portion in FIG. Since the portion is narrowed and the flat plate portion is interposed to increase the gap layer, the compressive strength of the bellows-bonded honeycomb cup is weakened. However, when the gap layer increases and the gap layer is filled with mortar, gypsum, diatomaceous earth, etc., which also strengthens the strength, the volume of the filling material is increased to increase the strength, and humidity control, flame retardant, sound insulation, etc. The function of the filling material can be demonstrated and there is an effective aspect.

  FIG. 11 shows that the bellows body 1-J of the bellows-bonded honeycomb cup body 15 is easy in the longitudinal direction (the direction across the parallel edges 3) when the direction in which the rectangular surfaces 1X are connected with the parallel edge 3 as a tangent is continuous. This shows that the shape can be changed. The honeycomb cup 6 can be easily bent by changing the cell pitch between the upper side and the lower side. FIG. 11 shows a side view of a wide bellows bonded honeycomb cup having a curved surface by bonding the wide bellows band 10 in a state where the honeycomb cup 6 is curved. The bellows-bonded honeycomb cup body 15 can be used for a cylindrical structure or the like by being curved, and the shape adaptation range for a curved structure such as an ellipse or a corrugated shape is widened.

Material can be used. Hereinafter, the structure of the present invention will be described in detail.

  The bellows-bonded honeycomb cup body shown in FIG. 1 is formed into a plate shape having a predetermined thickness, and the wide bellows band body 10 bonded to the honeycomb cup body 6 is placed with the honeycomb cup body 6 facing up. It is illustrated in a positioned state. In order to distinguish the wide bellows band body 10 from the honeycomb cup body 6, in the display of FIG. 1, the upper side is painted with diagonal lines and the lower side is painted with diagonal lines with different directions.

  The honeycomb cup body 6 is formed by regularly arranging the honeycomb cup-shaped cells 5 whose opening edges have a honeycomb shape. The honeycomb cup body 6 is configured by using the honeycomb cup cell 5 as a structural unit and connecting the parallel edges 3 and the chevron edges 4 that are the opening edges of adjacent ones so that the honeycomb concave portions cover the surface. The

  FIG. 3 illustrates a process in which the honeycomb goblet cell 5 is configured from the upper side of the drawing. This is a right end cell in which two triangular surfaces 2T are joined to two inclined surfaces 1 that are open at the top, which is a part of the bellows body 1-J, and a honeycomb line drawing is positioned on the upper surface on the right side in the upper part of FIG. It shows that “upward honeycomb cup type right end cell 5-1M” and “upward honeycomb cup type left end cell 5-1H” that is a left end cell having a honeycomb drawing on the upper surface on the left side are configured. In the middle of FIG. 3, the “upward honeycomb cup cell 5-1” which is a cell in which two triangular faces 2 T are joined to the left and right of the two inclined surfaces 1 whose upper part is open and the honeycomb line drawing is located on the upper surface. Indicates that it is configured. On the lower side of FIG. 3, there is a “downward-facing honeycomb cup cell 5-2” which is a cell in which two pairs of triangular faces 2T are joined to the left and right sides of the two inclined surfaces 1 which are open at the lower part, and the honeycomb drawing is located on the lower surface. Indicates that it is configured.

  The left side of the honeycomb cup body 6 shown in FIG. 1 on the same plane has an upward honeycomb cup type left end cell 5-1H shown in FIG. 3, and the right side of the same plane shows an upward honeycomb cup type right side shown in FIG. The end cell 5-1M is arranged. The above is an example of the method of configuring the end cell, but the present invention is not limited to this method.

From the upper side of FIG. 4, the honeycomb cups 5 are connected to the honeycomb cup-shaped cell rows 5A and the inter-cell chevron edge rows 5B and 5B connected to the honeycomb cup-shaped cell rows 5A and the side faces. The positional relationship of the type cell row 5C is shown. The honeycomb goblet cell row 5C is represented by one downward honeycomb goblet cell 5-2 for the sake of simplicity. The interval between the parallel edges 3 on the same plane of the honeycomb goblet cell 5 is defined as a cell pitch and is abbreviated as SP. The honeycomb goblet cell 5 (downward facing honeycomb goblet cell 5-2 in FIG. 4) is joined to the adjacent honeycomb goblet cell 5 at a half cell pitch in the lateral direction, and the honeycomb goblet body 6 is formed into a planar shape. Configure.
The length of the parallel edge 3 of the honeycomb cup type cell 5 is defined as a cell width and is abbreviated as SW. The cell width SW can be changed for each honeycomb cup type cell row. The cell width SW is also the horizontal length of the rectangular surface 1X, but the vertical length of the rectangular surface 1X is the bellows surface vertical length and is expressed as JL.

  The wide bellows band 10 has a wide bellows surface 7 joined in a bellows shape. The dimensional relationship between the wide bellows band 10 and the honeycomb cup body 6 is as shown in FIG. The spacing between the parallel edges of the wide bellows surface 7 is one-half the cell pitch (SP / 2), and the vertical length of the wide bellows surface 7 is 1/2 of the bellows surface vertical length of the honeycomb cup 6 (JL / 2). The shape of The honeycomb cup 6 and the wide bellows band 10 having the dimensions are joined to each other to form the bellows-joined honeycomb cup 15 of the present invention.

  In FIG. 2, the wide bellows band side support surface 11 is joined to the lower part of the bellows-bonded honeycomb cup body 15, the honeycomb cup body side support surface 14 is joined to the upper part, and the bellows-bonded honeycomb cup body is sandwiched between the upper and lower plate members. A panel-like form is shown. In the lower side of FIG. 2, a side view of the bellows body 1-J of the honeycomb cup-shaped cell row 5A cut vertically is shown with LA and LB of the honeycomb cup-shaped cell row 5A with both supporting surfaces attached. It shows by the part cut out in the range. Although the void portion is displayed without being painted to make it easy to see the shape of the honeycomb cup side view 6S, it can be drawn that a wide void layer is formed inside the bellows-bonded honeycomb cup. The void layer other than the in-plane void portion 5U of the honeycomb cup, that is, the void layer 12 under the honeycomb cup body and the void layer 13 under the wide bellows band are filled with granules or liquid material from the side surface even after completed as a panel or other product. There is an effect that can be easily done.

The bellows-bonded honeycomb cup can be manufactured as follows. 14 and 15 show a method of making the honeycomb cup 6 with a sheet material that can be bent and bonded, such as paper or resin.
On the lower side of FIG. 14, the sheet material is cut out from the original material by a solid line connecting the zigzag with D1, D2, and D3 as end points and a solid line connecting the zigzag with the end points E1, E2, and E3 and cut into a strip shape at the same time. 2B, 2C, a triangular belt-like sheet 2X with a crease line is shown. On the upper side of FIG. 14, the lined portion is bent into the shape of a triangular plane connecting band 2Y. The triangular edge 4 is constituted by 2A and 2B of the triangular plane connection band 2Y, and 2C is a boundary line connecting the two faces of the triangular plane 2. The triangular surface 2 is assumed to be symmetrical with respect to a boundary line 2C connecting the two surfaces.

  In the upper side of FIG. 15, a rectangular sheet 1XNS with a rectangular surface margin is obtained by attaching a rectangular surface margin 1XN to the side surface of the rectangular surface 1X and cutting from the original material. The rectangular surface margin 1XN is shown with diagonal lines, but a line connecting the rectangular surface margin 1XN and the rectangular surface 1X and a parallel edge 3 indicated by a one-dot chain line are provided with a crease line. The belt-like sheet 1XNS with the rectangular surface margin is bent at the lined parallel edge 3 to form a bellows shape, and is bent at the tangent line between the rectangular surface margin 1XN and the rectangular surface 1X, as shown in the center left side of FIG. The honeycomb goblet cell 5 is joined to the rectangular surface paste allowance 1XN and the triangular face connecting band 2Y. If attention is paid to the individual honeycomb cup-shaped cells 5, the triangle surface two pairs 2T are joined to the rectangular surface paste allowance 1XN. In FIG. 15, the downward honeycomb cup-shaped cell 5-2 is simply shown, but the honeycomb cup body is formed by continuously bonding the rectangular surface paste margin 1XN to the triangular surface connecting band 2Y. .

  The shape of the honeycomb goblet-shaped cell 5 also changes the angle of the two inclined surfaces and the shape of the chevron edge even when it is joined to the same two inclined surfaces 1 depending on the shape of the triangular surface 2. The boundary edge 2A, the boundary edge 2B, and the boundary edge 2C can be changed, whereby the hexagonal shape of the opening edge, the cell pitch can be changed, and the height of the honeycomb cup body 6 can also be changed.

  Honeycomb cup 6 can be made by folding and bonding paper or resin, etc., but the method using rectangular surface paste 1XN is an example. it can. In addition, materials such as plastic and metal can be formed by injection molding or press molding.

The material of the honeycomb cup body 6 and the material of the wide bellows band body 10 can be selected so as to be appropriate depending on the purpose of the utilization method of the gap layer 12 under the honeycomb cup body. Next, an example is given.
(1) For the purpose of heat dissipation for heating, the honeycomb cup body 6 uses a heat dissipation material, and the wide bellows band 10 uses a heat insulating material.
(2) The honeycomb cup body 6 is made of a breathable material, and the wide bellows band body 10 is made of a non-breathable material for the purpose of filling the honeycomb cup lower gap layer 12 with a fragrance and diffusing it.

When the wide bellows band side support surface 11 is used while being joined to the wide bellows band body 10, a wide bellows band lower gap layer 13 can be formed, but the above example and Similarly, the material of the wide bellows band side support surface 11 and the material of the wide bellows band body 10 can be selected. Further, the wide bellows band body 10 can be perforated and the honeycomb cup lower gap layer 12 and the wide bellow band lower gap layer 13 can be used as one body.
(1) Filling both the honeycomb cup body gap layer 12 and the wide bellows band gap layer 13 with a heat insulating and sound insulating granular material (ceramic, sand, etc.) while maintaining the shape of the honeycomb cup body 6 To do.
(2) Maintaining the shape of the honeycomb cup 6 in both the honeycomb cup lower gap layer 12 and the wide bellows band lower gap layer 13 with an initially incombustible or flame retardant liquid material (mortar, gypsum, etc.) Fill while doing. The filled material is solidified with the wide bellow band side support surface 11 in between, so that nonflammability or flame retardancy is improved and strength is increased.

  The bellows-bonded honeycomb cup 15 can be used as a single layer, but a plurality of sheets can be laminated to have a desired thickness and strength. By laminating, the target functions such as thickness adjustment, sound absorption / sound insulation, heat insulation, diffusion, and strength enhancement can be expanded. Although not shown, as another example, if the two bellows-bonded honeycomb cups 15 are bonded to the wide bellows band side support surface 11 so that the bellows of the wide bellows band 10 intersect 90 degrees, the longitudinal shear force And a horizontal shearing force with the same strength can be realized, and the strength becomes stronger.

  The bellows-bonded honeycomb cup body 15 can exhibit functions such as strength enhancement, soundproofing, heat insulation, humidity control, diffusion of fragrance, and the like by filling with other materials. The filling method of the material is solid. As shown in FIG. 12, the bellows joint in which the filler 16 is easily added by joining the wide bellows band 10 after the filler material is first placed or bonded to the honeycomb cup body 6 having the honeycomb line drawing on the lower surface. A honeycomb cup 15 can be produced.

  When the filling material is initially a liquid material such as gypsum or mortar, or a granular material such as sand or activated carbon, the upper and lower sides of the bellows-bonded honeycomb cup body 15 are fixed in a jig shape, and the side below the honeycomb cup body gap layer is formed. It can be injected and filled from 12 openings. For example, the mortar can be filled in the inside of the honeycomb cup lower void layer 12 in an uncured state and then cured to increase the strength and enhance the sound insulation and flame retardant functions.
