Even when the soundproof hollow synthetic resin material 100 is used for the roofing material, the wall material or the window material, the soundproof properties are improved by reducing leakage of a sound to an indoor side by means of the long solid material 120 which is inserted through the hollow portion 113 of the hollow synthetic resin material body 110.

Description

  The present invention relates to a soundproof synthetic resin hollow material and a soundproof structure using the same.

In recent years, a synthetic resin hollow material having a hollow portion partitioned by a plurality of flat plates and a plurality of ribs facing each other has been used as a lighting roof material, wall material, or window material.
Such a synthetic resin hollow material is lighter and has better heat insulation than a synthetic resin solid material of the same thickness, but for example, the sound of raindrops colliding with one surface of a synthetic resin hollow material is synthesized. In some cases, improvement in soundproofing is desired, for example, in order to reduce rain noise transmitted to the other surface side of the resin hollow material.

As a method for reducing the rain noise of the roofing material, Patent Document 1 describes a method of laminating a damping sheet on the back surface of a folded plate roof as a known technique. Further, in Patent Document 2, as a method for improving the soundproofing property of the hollow material, a rubber chip sheet and a nonwoven fabric in which rubber chips are bonded with a binder are laminated on the front and back surfaces of a thermoplastic resin hollow plate reinforced by a plurality of bridges. The laminated rubber chip / nonwoven fabric composite sheet is laminated, and the upper and lower ends of the hollow plate are covered with the upper and lower ends of the rubber chip / nonwoven fabric composite sheet, and the substantially U-shaped cross-section cover section prevents the peeling. A sound insulation wall is proposed.

JP 2000-301640 A Japanese Patent Application Laid-Open No. 07-317022

    However, in the folded plate roof of Patent Document 1, a vibration damping sheet is laminated on the back surface of the folded plate roof, so the sound insulating wall of Patent Document 2 is a rubber chip in which rubber chips are bonded to the front and back surfaces of a thermoplastic resin hollow plate with a binder. Since the rubber chip / nonwoven fabric composite sheet on which the sheet and the nonwoven fabric are overlapped is laminated, the vibration damping sheet or the rubber chip sheet or the rubber chip / nonwoven fabric composite sheet may be peeled off over time, resulting in a decrease in soundproofing. It was difficult to provide soundproofing.

  The present invention has been made under the circumstances described above, and the problem to be solved is to provide a soundproof synthetic resin hollow material in which a decrease in soundproofness over time is reduced and the required soundproofness can be easily imparted. There is to do.

  In order to solve the above problems, a soundproof synthetic resin hollow material according to claim 1 of the present invention has a hollow portion partitioned by a plurality of flat plates and a plurality of ribs facing each other, and both ends of the hollow portion are A synthetic resin hollow material main body having an opening and a solid long material inserted into at least one hollow portion of the synthetic resin hollow material main body are provided.

  The soundproof synthetic resin hollow material according to claim 2 of the present invention is characterized in that the solid long material is thicker than the flat plate.

The soundproof synthetic resin hollow material according to claim 3 of the present invention has at least two hollow portions in the thickness direction of the synthetic resin hollow material main body because the number of the flat plates is three or more. It is characterized by being.

  In the roof, wall or window structure according to claim 4 of the present invention, the soundproof synthetic resin hollow material or one or more soundproof synthetic resin hollow materials are arranged in the width direction. It is characterized by being covered with a frame material.

According to invention of Claim 1, the synthetic resin hollow material main body which has the hollow part partitioned off by the some flat plate which mutually opposed, and the some rib, and the both ends of the said hollow part are open, and the said synthetic resin Since the solid long material inserted into at least one hollow portion of the hollow material main body is provided, the soundproofing property of the soundproof synthetic resin hollow material can be improved.

  According to invention of Claim 2, since the thickness of the said solid elongate material is thicker than the said flat plate, the soundproofing of the soundproofing synthetic resin hollow material by the combination of two effects of the weight effect mentioned later and a coincidence effect The property can be further improved.

  According to invention of Claim 3, since it has at least 2 or more hollow parts in the thickness direction of the said synthetic resin hollow material main body because the said flat plate is 3 or more, it is a solid long material. Since the number of hollow parts that can be inserted increases, the range of selection of the number of long materials is expanded according to the required soundproofing and weight, making it easier to adjust the soundproofing and weight of the soundproofing synthetic resin hollow material. .

  According to the invention of claim 4, one soundproof synthetic resin hollow material according to any one of claims 1 to 3 or two or more soundproof synthetic resin hollow materials are arranged in the width direction. However, by covering the outer peripheral portion with a frame material, it is possible to provide a soundproof roof, wall or window structure having excellent wind pressure resistance.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described with reference to the drawings. However, the present invention is not limited to the configuration described in the embodiment, and the configuration can be changed as appropriate without departing from the spirit of the present invention.

  A soundproof synthetic resin hollow material according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  Fig.1 (a) is a perspective view of the soundproof synthetic resin hollow material 100 which shows one Embodiment of this invention, FIG.1 (b) is the elements on larger scale of the width direction edge part of Fig.1 (a). It is. FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG.

As shown in FIG. 1A, the soundproof synthetic resin hollow material 100 is a synthetic resin hollow material having hollow portions 113 and 114 partitioned by four flat plates 111 and a plurality of ribs 112 facing each other. The main body 110 and the solid elongate material 120 inserted in many hollow parts 113 of the said synthetic resin hollow material main body 110 are provided.

  The four flat plates 111 of the synthetic resin hollow material body 110 facing each other have substantially the same length and width, and are arranged in parallel so that their surfaces face each other in the order of 111a, 111b, 111c, and 111d. . Further, the plurality of ribs 112 of the synthetic resin hollow material body 110 includes the following three types of ribs. One type of rib is a rib 112a that is substantially perpendicular to the four flat plates and is in contact with both ends in the width direction of the flat plates 111a to 111d, and the other type of rib is substantially perpendicular to the four flat plates 111a to 111d and described above. This is a rib 112b that is in contact with or intersects at other than the ends in the width direction of the flat plates 111a to 111d. Still another type of rib is a rib 112c that forms a hollow portion 114 (described later) in the vicinity of the ends in the width direction of the flat plates 111a to 111d. As shown in FIG. 1B, the rib 112c may be substantially perpendicular to the flat plates 111a to 111d or may be substantially parallel to the flat plates 111a to 111d. Note that each of the ribs 112a, 112b, and 112c is substantially planar, and the length is substantially equal to the length of the recording plate 111.

The synthetic resin hollow material body 110 has two types of hollow portions. One type is a large number of hollow portions 113 having a substantially rectangular cross section of substantially the same shape partitioned by flat plates 111a to 111d and ribs 112b. The hollow portion 113 includes a hollow portion 113ab partitioned by a flat plate 111a, a flat plate 111b, and a rib 112b, a hollow portion 113bc partitioned by the flat plate 111b, the flat plate 111c, and the rib 112b, a flat plate 111c, a flat plate 111d, and a rib 112b. There is a hollow portion 113cd partitioned by. Another hollow portion is a hollow portion 114 having a cross-sectional shape different from that of the above-described hollow portion 113 in the vicinity of the width direction end portion of the flat plate 111. Further, since neither of the hollow portions 113 and 114 is obstructed in the length direction of the flat plate 111 and the rib 112, both ends in the length direction of the synthetic resin hollow material body 110 are open.

  At both ends in the width direction of the synthetic resin hollow material main body 110, there are provided hollow hook portions 115 projecting toward the flat plate 111 d side in the thickness direction over the entire length in the length direction of the synthetic resin hollow material main body 110. Yes. Further, the hooking portion 115 includes a protruding piece 115a and a hooking piece 115b. Two hooking pieces 115b, 115b provided in two hooking portions 115, 115 provided at both ends in the width direction of one synthetic resin hollow material main body 110 are provided so as to face each other (both inward in the width direction). It has been. As will be described later, the hook 115 is sandwiched between the connecting members 130 when connecting the adjacent synthetic resin hollow material bodies 110, 110 in the width direction of the synthetic resin hollow material body 110.

  The dimensions of each part of the synthetic resin hollow material main body 110 are not particularly limited. In this embodiment, the thickness of the synthetic resin hollow material main body 110 (the distance from the outside of the flat plate 111a to the outside of the flat plate 111d) is about 16 mm, and the width. The thickness of the flat plates 111a and 111d and the ribs 112a is about 1 mm, and the thickness of the flat plates 111b and 111c, the ribs 112b and the ribs 112c is about 0.5 mm. Protrudes about 14 mm toward the 111d side, and the interval between the ribs 112b is about 20 mm.

  As the material of the hollow body 110 made of synthetic resin, various thermoplastic resins such as polyvinyl chloride, polyacryl, polyolefin, and polyester can be used. Among them, polycarbonate has a balance of strength, moldability, price, and the like. The high-quality synthetic resin-made intermediate material main body 110 can be manufactured at a relatively low cost, and is therefore preferably used. The whole or a part of the synthetic resin hollow material body 110 made of polycarbonate contains an ultraviolet absorber, a light stabilizer and / or an antioxidant, or the ultraviolet absorber, the light stabilizer and / or It is preferable to improve the weather resistance by providing a layer having an antioxidant or the like. Further, a known additive such as a pigment and / or a heat ray absorbing material may be added to the whole or a part of the hollow body 110 made of synthetic resin made of polycarbonate, and may be antifogging, antistatic and / or antifouling. A known functional layer such as the above may be provided.

  In addition, the flat plate of a synthetic resin hollow material body is not limited to four, and may be two or more that can form a hollow portion. Moreover, the number of the ribs of the synthetic resin hollow material main body may be two or more that can form the hollow portion.

  The solid long material 120 inserted into the hollow portion 113 of the synthetic resin hollow material main body 110 increases the weight of the soundproof synthetic resin hollow material 100 and further the space of the hollow portion 113 of the synthetic resin hollow material main body 110. By reducing the value, the soundproofing property of the soundproofing synthetic resin hollow material 100 is improved.

As long as the solid long material 120 is a size that can be inserted into the hollow portion 113 of the synthetic resin hollow material main body 110, the cross-sectional shape is not limited, but in this embodiment, as shown in FIG. It has a substantially rectangular cross-sectional shape that is slightly smaller overall than the cross-sectional shape of 113.

In consideration of the mass effect that can improve soundproofing by increasing the weight of the plate material, the synthetic resin hollow material is inserted by inserting the solid long material 120 into the hollow portion 113 of the synthetic resin hollow material body 110. Since the weight of the main body 110 increases, the soundproofing property of the synthetic resin hollow material main body 110 can be improved. If the solid long material 120 having the same specific gravity is used, the solid long material 120 has a larger cross-sectional area and a longer length. Longer is preferred. Furthermore, in order to increase the cross-sectional area of the solid long material 120, it is necessary to increase the width and thickness of the solid long material 120. Therefore, it is preferable that the hollow material 120 has a large width and thickness and a long length.

Further, if there is a large gap between the hollow portion 113 of the synthetic resin hollow material body 110 and the solid long material 120, the synthetic resin hollow material body 110 vibrates when the synthetic resin hollow material body 110 vibrates due to wind or the like. If the solid long material 120 inserted into the hollow portion 113 of the 110 is rattled in the hollow portion 113, it may collide with the flat plate 111 or the rib 112b forming the hollow portion 113 to generate a collision sound. Therefore, the solid long material 120 preferably has a cross-sectional shape with little or no gap with the hollow portion 113 of the synthetic resin hollow material body 110. Furthermore, if a gap (space) exists between the solid long material 120 and the hollow portion 113 of the synthetic resin hollow material main body 110, resonance due to the size of the gap occurs, and therefore at a specific frequency. Sound insulation is reduced. Therefore, the cross-sectional shape of the solid long material 120 is more preferably slightly smaller as a whole than the cross-sectional shape of the hollow portion 113 of the synthetic resin hollow material main body 110, and a shape in which the gap becomes as small as possible when inserted.

  When the length of the solid long material 120 is shorter than the length of the hollow portion 113 of the synthetic resin hollow material main body 110, the solid long material 120 moves in the length direction in the hollow portion 113. In addition, there is a possibility that the design property of the synthetic resin hollow material main body 110 having translucency may be deteriorated due to the difference in translucency depending on the presence or absence of the solid long material 120. As shown in FIG. 2, it is preferable that the length of the hollow portion 113 of the synthetic resin hollow material main body 110 is substantially the same as the length of the synthetic resin hollow material main body 110 and is inserted over the entire length.

  As the material of the solid long material 120, synthetic resin, glass, metal and the like can be used, but a soundproof synthetic resin hollow material used as a light roofing material, wall material or window material for lighting, etc. In order to obtain 100, a light-transmitting synthetic resin is suitable. As the translucent resin, various thermoplastic resins such as polyvinyl chloride, polyacryl, polyolefin and polyester can be used. Among them, polycarbonate has a good balance of strength, moldability, price, etc., and has high quality. Since the solid long material 120 can be manufactured relatively inexpensively, it is particularly preferably used. It is preferable to increase the weather resistance by adding a UV absorber or a light stabilizer to the solid solid material 120 made of such a polycarbonate, or providing a layer having a UV absorber. Further, the polycarbonate solid long material 120 may be added with known additives such as an ultraviolet absorber, a pigment, a light diffusing agent and / or a heat ray absorbing material, and the ultraviolet absorber, the pigment, the light diffusing agent. In addition, a known functional layer such as a heat ray absorbing material may be provided.

In addition, considering the coincidence effect that the soundproofness is reduced at a specific frequency due to the material and thickness, the solid long material 120 may be different in material and / or thickness from the synthetic resin hollow material body 110. preferable. This is because if the material is the same, the specific frequency at which the soundproofing property is lowered is determined by the thickness. Therefore, if the thickness of the solid long material 120 and the flat plate 111 of the synthetic resin hollow material body 110 is different, the soundproofing property is obtained. This is because the specific frequency to be reduced is different, and the decrease in soundproofing at the specific frequency due to the thickness of one can be compensated by the other. In addition, when the thickness of the long hollow material 120 and the synthetic resin hollow material main body 110 are the same, the specific frequency at which the soundproofing property is lowered is determined by the material, so the solid long material 120 and the synthetic resin hollow material By selecting a material having the same thickness as the main body 110 and having a different specific frequency at which the soundproofing performance is reduced, it is possible to compensate for the decrease in the soundproofing performance at a specific frequency caused by one material. . However, since the materials of the long hollow material 120 and the synthetic resin hollow material main body 110 are different and have the same thickness, a combination of materials having the same specific frequency at which the soundproofing property is reduced can be considered. It is more preferable that the long hollow material 120 and the synthetic resin hollow material main body 110 are made of the same material and have different thicknesses so that the above can be expressed with certainty. Moreover, when the material and thickness of the solid long material 120 and the synthetic resin hollow material main body 110 are different, the material and the thickness may be selected so that specific frequencies at which the respective soundproofing properties are reduced are different. preferable.

In addition, the “solid long material” referred to in the present invention means a long material that is substantially free of bubbles and spaces. Accordingly, a long material made of foamed synthetic resin and a hollow long material made of synthetic resin are not included in the “solid long material” referred to in the present invention. However, a long material made of a synthetic resin in which a small amount and / or extremely small bubbles that can be generated unintentionally in the manufacturing process are included in the “solid long material” of the present invention.

The number of the solid long materials 120 may be appropriately selected in consideration of the weight, soundproofing, heat insulating properties, etc. required for the soundproofing synthetic resin hollow material 100, and are shown in FIGS. 3 (a) to 3 (c). Thus, it may be inserted into all or part of the hollow portion 113 of the synthetic resin hollow material body 110. Moreover, when there are a plurality of hollow portions 113 in the thickness direction of the synthetic resin hollow material body 110 as in this embodiment, the solid long material 120 may be inserted in all or part of the thickness direction. . When the number of the solid long members 120 is large, the weight of the soundproofing synthetic resin hollow material 100 is increased, so that the soundproofing property can be improved. On the other hand, the advantage of the lightweight hollow material may be impaired. In the soundproof synthetic resin hollow material 100 shown in FIG. 1 (a), the solid long material 120 is inserted into all the hollow portions 113 cd of the hollow portions 113 of the synthetic resin hollow material main body 110. This is because the long hollow material 120 is inserted into the hollow portion 113cd located on the outdoor side and partitioned by the flat plate 111d on which raindrops hit during construction, so that the soundproofing property on the most outdoor side of the soundproof synthetic resin hollow material 100 is achieved. As a result, sound transmission to the inside of the soundproof synthetic resin hollow material 100 can be reduced, so that resonance in the hollow portions 113ab, 113bc and 114 into which the solid long material 120 is not inserted is achieved. This is because it can be reduced. Furthermore, in comparison with the case where the solid long material 120 is inserted into all the hollow portions 113, when the solid long material 120 is inserted into all the hollow portions 113cd, the soundproof synthetic resin hollow An increase in the mass of the material 100 can be suppressed. Therefore, both the soundproofing and the light weight and excellent heat insulation, which are the advantages of the hollow body, can be achieved.

Note that the solid long material can be inserted into the hollow portion 114. In this case, preferable conditions and the like are the same as those of the solid long material 120 to be inserted into the hollow portion 113, and thus description thereof is omitted.

Both ends of the opening in the length direction of the hollow body 110 made of synthetic resin are for preventing dew condensation and / or preventing foreign matter, rainwater, etc. from entering the hollow portion 113 after the solid long material 120 is inserted. It is preferable to seal with aluminum tape or the like.

Next, the soundproof roof structure 1 using the soundproof synthetic resin hollow material 100 will be described with reference to FIGS.

4A is a perspective view of the soundproof roof structure 1 showing an embodiment of the present invention, and FIG. 4B is a horizontal frame member 141 of the soundproof roof panel 140 of FIG. 4A. FIG. 5 is a sectional view of the connection member 130, FIG. 6 (a) is a perspective view of the horizontal frame member 141, and FIG. 6 (b). FIG. 7A is a perspective view of the vertical frame member 142, FIG. 7A is a cut end view taken along the line BB ′ in FIG. 4, and FIG. 7B is a view of two sheets of FIG. It is the elements on larger scale near the connection part of the soundproof synthetic resin hollow materials 100 and 100, and FIG. 8 is sectional drawing along CC 'line of FIG.

The soundproof roof structure 1 includes a soundproof roof panel 140 and a casing 150 which will be described later.

The soundproof roof panel 140 includes three soundproof synthetic resin hollow materials 100 having the same length, two connection materials 130 for connecting the adjacent soundproof synthetic resin hollow materials 100, and a connection material 130. The two horizontal frame members 141 that are externally fitted to both ends in the length direction of the three soundproof synthetic resin hollow materials 100 connected in the above, and the three soundproof synthetic resin hollow materials connected by the connection material 130. It consists of two vertical frame members 142 that are fitted around both ends in the width direction of 100. In this embodiment, the lengths of the three synthetic resin hollow material bodies 110 are all about 2 m, and two of the three synthetic resin hollow material bodies 110 used at both ends are the width of the roof. In order to meet this requirement, the entire length is cut at the intermediate portion in the width direction.

As shown in FIG. 5, the connecting member 130 includes a hollow top surface portion 131, two hollow side surface portions 132 that respectively hang downward from both ends of the top surface portion 131, and the side surface portion 131 parallel to the two side surface portions 132. It is a long material with a substantially E-shaped cross section having a partially hollow partition part 133 suspended from the substantially central part. Each opposing surface side of the two side surface portions 132 of the connecting material 130 has a shape corresponding to the shape of the hook portion 115 of the synthetic resin hollow material body 110 described above.

As a material of the connecting material 130, synthetic resin, metal, or the like can be used, but in this embodiment, polycarbonate is used. In the case of a synthetic resin, it is preferable to use a material having a daylighting property because a decrease in the daylighting property of a roof, a wall, a window structure or the like including the soundproofing synthetic resin hollow panel and the connecting member 130 is suppressed. Moreover, when using a synthetic resin, each part which comprises the connection material 130 may be equipped with a rib in a hollow part, and is good also as a solid. On the other hand, in the case of metal, aluminum that is lightweight and excellent in formability is preferably used.

As shown in FIG. 7 (b), in the two space portions 134 and 134 formed by the top surface portion 131, the two side surface portions 132 and the partition portion 133 of the connecting member 130, the synthetic resin hollow material body 110 is respectively formed. A hook 115 is inserted. Note that the side surface of the side surface portion 132 forming the space portion 134 on the space portion 134 side is substantially the same sectional shape as the hook portion 115 of the synthetic resin hollow material main body 110 (particularly, a recess corresponding to the hook piece 115b). Part). Further, the distance between the side member 132 and the partition member 133 is slightly wider than the width of the hook portion 115 of the synthetic resin hollow material main body 110. Therefore, the connecting member 130 is combined with the hook portion 115 of the synthetic resin hollow material 110 to fit the hook portions 115 and 115 adjacent to the two synthetic resin hollow material bodies 110 and 110 to be connected. And once fitted, it is difficult to come off.

As shown in FIG. 6 (a), the lateral frame member 141 is a long material having a U-shaped cross section composed of a side surface portion 141a, a top surface portion 141b and a bottom surface portion 141c that are suspended from both ends of the side surface portion 141a. The length L1 is substantially equal to the full width w of the connected synthetic resin hollow material main body 110. The height of the side surface portion 141a is obtained by adding the height H130 of the connecting material 130 to the thickness T of the synthetic resin hollow material body 110 in the vicinity of the portion corresponding to the portion where the hook portion 115 of the synthetic resin hollow material body 110 is present. The other part is slightly wider than the thickness T of the soundproof synthetic resin hollow material body 110 (H2). For this reason, the horizontal frame member 141 can externally fit the end portion in the length direction of the synthetic resin hollow material main body 110.

The vertical frame member 142 is a long material having a U-shaped cross section composed of a side surface portion 142a, a top surface portion 142b and a bottom surface portion 142c suspended from both ends of the side surface portion 142a, and its length L2 is a hollow made of synthetic resin. It is substantially equal to the length L of the material main body 110, the height of the side material 142a is the same as H2 of the horizontal frame material 141, and is slightly wider than the thickness T of the synthetic resin hollow material main body 110. For this reason, the vertical frame material 142 can fit the width direction edge part of the synthetic resin hollow material main body 110 externally. In addition, since the length of the vertical frame material 142 and the length of the soundproofing roof panel 140 are equal, both are described as L2.

The material of the horizontal frame member 141 and the vertical frame member 142 is not particularly limited, but may be appropriately selected in consideration of the application and load resistance. In this embodiment, it consists of an aluminum material.

As shown in FIG. 4 (b), in the vicinity of each joint portion of the horizontal frame member 141 and the vertical frame member 142 of the soundproof roof panel 140, the side frame member 141 and the vertical frame member 142 are arranged so as not to overlap each other. The angle θ1 between the end of the materials 141a and 142a and the end of the side frame 141b and the end of the side frame 142b and the end of the side frame 142b of the vertical frame 142 Notches are formed so that the angle θ2 formed is approximately 45 °. The sealing and sealing of the horizontal frame member 141 and the vertical frame member 142 including the notched end portion improve the watertightness and airtightness of the soundproofing roof panel 140.

Further, by inserting a packing or the like between the horizontal frame member 141 or the vertical frame member 142 and the soundproof synthetic resin hollow material 100, water tightness and air tightness can be improved and rattling can be prevented. Furthermore, by sealing so as to cover the exposed surface of the packing, the waterproofness and airtightness of the soundproofing roof panel 140 can be improved.

As shown in FIG. 4A, the soundproof roof panel 140 is obtained by connecting three soundproof synthetic resin hollow materials 100 in the width direction by the connection materials 130 using the two connection materials 130. The four circumferences are externally fitted and covered with two horizontal frame members 141 having a U-shaped cross section and two vertical frame members 142 having a U-shaped cross section. For this reason, the soundproofing roof panel 140 has a structure in which the soundproofing synthetic resin hollow material 100 is not easily detached even by wind pressure or the like. As described above, the horizontal frame member 141 and the vertical frame member 142 provide excellent wind pressure resistance to the soundproofing roof panel 140 by covering and covering the soundproofing synthetic resin hollow material 100 and the connecting material 130. To play a role.

The casing 150 includes a column member 151 having one end buried in the ground and a beam member 152 extending to the other end of the column member 151.

The material, shape, and number of the column members 151 are not particularly limited, but may be appropriately selected in consideration of the use, the size of the roof, the load resistance, and the like. In this embodiment, two column members 151 made of a hollow aluminum material having a length of about 2 m and a rectangular cross section are used.

The material and shape of the beam material 152 are not particularly limited, but may be appropriately selected in consideration of the application, the size of the roof, the load resistance, and the like. In this embodiment, the length is made of a hollow aluminum material having a rectangular shape and a cross section of about 2 m which is substantially equal to the length L2 of the soundproofing roof panel 140.

The beam member 152 may be supported by the column member 151 at one end, at both ends, or at least three points. The method of supporting the beam member 152 is determined appropriately depending on the application, the size of the roof, the load resistance, and the like. It only has to be selected. In this embodiment, as shown in FIG. 6A, the column material 151 supports the beam material 152 at one end of the beam material 152.

The soundproof roof structure 1 is obtained by installing and fixing the soundproof roof panel 140 on the upper surface of the beam member 152. In this embodiment, since the length of the beam member 152 is substantially equal to the length L2 of the soundproof roof panel 140, both ends of the beam member 152 and the horizontal frame member 141 of the soundproof roof panel 140 are fixed by screws. . The fixing method is not limited to screws, and any known fixing method can be employed.
