Description

この発明は、アルミ押出形材からなるデッキ材を敷き並べてデッキが構成されるベランダやバルコニー、物干し台等において、踏み足で掛かる重みや風力による揺れ等で金属どうしが接触面で擦り合って軋む金属音が発生しないようにした防音デッキ構造に関する。 In the present invention, in a veranda, balcony, clothes rack, etc., in which deck materials made of extruded aluminum are laid side by side, the metal rubs on the contact surface due to the weight applied by the foot or the vibration caused by wind force. The present invention relates to a soundproof deck structure in which metal sound is not generated.

ベランダやバルコニー、物干し台等においては、雨水や太陽光により朽ちないアルミ押出形材からなる根太やデッキ材が多用され、デッキ材を整然と秩序正しく並べるためや相互に持たせるために隣接デッキ材を付き合わせてビス止めされる。また、強度上から中空に形成されるが、根太に下面壁で安定してビス止めする必要から、下面壁が底壁となる凹部が設けられる。しかし、それを排水溝とすることはビス孔を有することとの関係で適当ではないので、一端にＬ字形またはそれに近い形状のＬ字形片により排水溝が設けられる。 On verandas, balconies, clothes racks, etc., joists and deck materials made of extruded aluminum that do not decay due to rainwater or sunlight are often used. Attached and screwed. In addition, it is hollow from the viewpoint of strength, but since it is necessary to be securely screwed to the joist with the lower wall, a recess having the lower wall serving as the bottom wall is provided. However, since it is not appropriate to use the drainage groove as the drainage groove, the drainage groove is provided at one end with an L-shaped piece having an L shape or a shape close thereto.

デッキ材はこれが直行するよう配列されている根太等にビス止めされるが、殊に根太と根太との間が踏まれたときにそのデッキ材が僅かではあるが人の重みで撓むこととなり、このときに隣接するデッキ材と接触面で擦り合い軋む金属音が騒音として発生する。また、殊に支柱の上にデッキを設けた屋根利用の車庫等においては、風を受けて揺れが発生しやすいので、それが原因で同じように金属音が発生する。また、デッキ材どうしの他に、根太との接触部分で同じように軋む金属音が発生することがあった。 The deck material is screwed to the joist etc. arranged so that it goes straight, but the deck material will be bent slightly by human weight, especially when stepped between the joists. At this time, a metal sound that rubs against the adjacent deck material on the contact surface is generated as noise. In particular, in a garage using a roof provided with a deck on a support column, it is easy to generate a shake due to the wind, which causes a metal sound as well. Further, in addition to the deck materials, there was a case where a metal sound crammed in the same manner at the contact portion with the joists.

上記の問題を解決するために種々実験と研究を重ねた結果、軋むような金属音の発生は、金属面どうしの密着した面接触が原因で摩擦抵抗が大きいときに、抵抗による変形が瞬間的に微細に継続して発生する振動によることが分かった。また、排水溝を構成するために振動しやすいＬ字形片を突設してあると、その弾性で他のデッキ材との密着が確実となるため、利点があるものの金属音の発生が多いことも分かった。 As a result of repeated experiments and researches to solve the above problems, the generation of a sizzling metal sound is caused by the momentary deformation of resistance when the frictional resistance is large due to the close contact between the metal surfaces. It was found that it was caused by vibrations generated continuously. In addition, if an L-shaped piece that is prone to vibrate is provided to form a drainage groove, its elasticity will ensure close contact with other deck materials. I understand.

この発明は、上記のような実情に鑑みて、根太の上に配列されるデッキ材が隣接どうしで接触するにもかかわらず、人が上にのった力で撓んだとしても、軋む金属音が発生しなくなるベランダ等における防音デッキ構造を提供することを課題とした。 In view of the above situation, the present invention is a metal that retains even if the deck material arranged on the joists come into contact with each other even if the person bends by the force that is on the top. It was an object to provide a soundproof deck structure on a veranda where no sound was generated.

上記の課題を達成するために、この発明は、根太の上に配列されるアルミ押出形材からなるデッキ材について、下面壁の上に左右１対の中空踏板部を形成し、一端に下面壁の延長としてＬ字形片が突設されることによりその側の中空踏板部とで排水溝が設けられ、他方にはその側の中空踏板部の外側面に突起条を形成してあって、デッキの組立てにおいて、Ｌ字形片を隣接デッキ材の突起条に押し当てた線接触が保持されるように、両中空踏板部間の凹部としての間隔で下面壁を根太にビス止めしたことを特徴とするベランダ等における防音デッキ構造を提供するものである。 In order to achieve the above object, the present invention provides a deck material made of an aluminum extruded profile arranged on a joist, wherein a pair of left and right hollow treads are formed on the lower surface wall, and the lower surface wall is formed at one end. As an extension of the L-shaped piece, a drainage groove is provided on the hollow tread portion on that side, and a protrusion is formed on the outer surface of the hollow tread portion on the other side. In the assembling, the bottom wall is screwed to the joist at the interval as a recess between both hollow tread parts so that the line contact with the L-shaped piece pressed against the protrusion of the adjacent deck material is maintained. It is intended to provide a soundproof deck structure in a veranda.

ベランダ等における防音デッキ構造を上記のように構成したから、根太の上にデッキ材を配列する際に、整然と平行に固定するために、先行するデッキ材に強く押し当てながらビス止めしても、突起条により線接触となるために、デッキ材の上にのった重みで撓んでも、摩擦の比較的少ない線接触であり、しかも、Ｌ字形片の弾性変形が伴うことによって、撓みで円滑な摺動となるので、その際に軋むような金属音が発生することはない。 Since the soundproof deck structure on the veranda etc. is configured as described above, when arranging the deck material on the joists, in order to fix it in an orderly manner, even if it is screwed while pressing firmly against the preceding deck material, Because of the line contact due to the protrusions, even if it bends due to the weight on the deck material, it is a line contact with relatively little friction, and the L-shaped piece is elastically deformed, so that the bend is smooth. As a result, the metal sound that glares at that time is not generated.

また、デッキ材について、突起条を有する中空踏板部からその上面壁の延長としてカバー片を逆Ｌ字形ないしコ字反転形に突設し、さらに、下面とＬ字形片とにわたって接触するプラスチックの押出形材が組み合わせてあると（請求項２）、Ｌ字形片がそれを被覆するプラスチックにより突起条と接触することになるので、金属音の発生が全くなくなることはもちろん、突起条とプラスチックとの結合により隣接両デッキ材の結合が安定する。さらに、金属製の根太とも金属どうしの接触がないので、その間においても金属音の発生を防止できる。また、Ｌ字形片がプラスチックによるカバー片で隠され、露出する箇所では足がそのＬ字形片の上に掛かっても痛みがプラスチックにより緩和される。 Further, for the deck material, a cover piece is projected in an inverted L-shaped or U-shaped inverted shape as an extension of the upper surface wall from the hollow tread portion having protrusions, and further, extrusion of plastic that contacts the lower surface and the L-shaped piece. When the shapes are combined (Claim 2), the L-shaped piece comes into contact with the protrusions by the plastic covering it, so that the generation of metal sound is completely eliminated and, of course, the protrusions and the plastic Bonding stabilizes the connection between adjacent deck materials. Furthermore, since there is no contact between the metal joists and the metal, the generation of the metal sound can be prevented even between them. Also, the L-shaped piece is covered with a plastic cover piece, and the pain is alleviated by the plastic even if the foot is placed on the L-shaped piece at the exposed portion.

以上説明したように、この発明によれば、根太の上に配列されるデッキ材が隣接どうしでたとえ強く接触しその状態で下面壁を強固に根太にビス止めしてあっても、人が上にのった力で撓んだときに、摩擦が比較的小さい突起条による線接触と、接触を弾力的とするＬ字形片による接触であることから、撓みによる摺動が抵抗なく円滑となるために、軋む金属音が発生しなくなり、また、デッキが強風による力を受けても金属音の発生を防止できるという優れた効果がある。 As described above, according to the present invention, even if the deck materials arranged on the joists are in strong contact with each other and the bottom wall is firmly screwed to the joists in that state, the person cannot When it is bent by the force applied, the line contact by the protrusion with relatively small friction and the contact by the L-shaped piece that makes the contact elastic, and the sliding by the bending becomes smooth without resistance. For this reason, there is an excellent effect that no metal sound is generated, and even when the deck receives a force of strong wind, the metal sound can be prevented from being generated.

図１および図２は、この発明の一実施の形態を示したもので、そのデッキ１は、根太３，３，・・に直行してその上に多数枚のデッキ材５，５，・・が敷かれ、その並びにおいて各デッキ材５に有する突起条６が隣接するデッキ材５に接触した状態で、各デッキ材５がビス７で根太３に止められる。 1 and 2 show an embodiment of the present invention, and the deck 1 of the deck 1 goes directly to the joists 3, 3,... And a plurality of deck members 5, 5,. The deck members 5 are fastened to the joists 3 with screws 7 in a state where the protruding strips 6 of the respective deck members 5 are in contact with the adjacent deck members 5.

デッキ材５は、アルミ押出形材からなるもので、その形材としての形状については、下面壁９を共通の一辺として左右１対の中空踏板部１１，１１を矩形に形成するとともに、その両中空踏板部１１，１１の間に凹部となる間隔１３が設けられる。したがって、両中空踏板部１１，１１には、下面壁９と中空を隔てて上面壁１２，１２を有する。そして、一方の中空踏板部１１の外側面の下端部近くに突起条６が形成される。なお、間隔１３の凹部底面には幅中央に沿ってビス７の通し孔を開ける位置決めとなる細溝１４が形成される。１８はビス７を根太３にねじ込む孔である。 The deck material 5 is made of an aluminum extruded shape. The shape of the shape of the deck material 5 is such that a pair of left and right hollow tread portions 11 and 11 are formed in a rectangular shape with the lower surface wall 9 as a common side, and both A space 13 serving as a recess is provided between the hollow tread portions 11 and 11. Therefore, both the hollow tread portions 11 and 11 have upper surface walls 12 and 12 that are spaced apart from the lower surface wall 9. And the protrusion 6 is formed near the lower end part of the outer surface of one hollow tread part 11. A narrow groove 14 is formed on the bottom surface of the concave portion of the interval 13 to be positioned to open the through hole of the screw 7 along the center of the width. Reference numeral 18 denotes a hole for screwing the screw 7 into the joist 3.

突起条６とは反対側において、デッキ材５の端には、下面壁９の延長部をＬ字形片１５に形成することにより中空踏板部１１との間に排水溝１７が設けられ、Ｌ字形片１５の起立部１６が他のデッキ材５の突起条６に線接触するようになっている。また、他端にはその側の中空踏板部１１の上面壁１２の延長部としてコ字形に反転するカバー片１９が突設され、排水溝１７と係合関係にそこに突入するように形成され、カバー片１９の内側上面の幅中央部に突片条２１が垂設される。 On the side opposite to the protrusion 6, a drainage groove 17 is provided at the end of the deck material 5 between the hollow tread plate portion 11 by forming an extension portion of the lower surface wall 9 in the L-shaped piece 15, and the L-shape. The standing portion 16 of the piece 15 is in line contact with the protrusion 6 of the other deck material 5. Further, at the other end, a cover piece 19 that reverses in a U-shape is projected as an extension of the upper surface wall 12 of the hollow tread portion 11 on that side, and is formed so as to enter the drainage groove 17 in an engaging relationship therewith. The protruding strip 21 is suspended from the center of the width of the inner upper surface of the cover piece 19.

突片条２１については、その内側にＬ字形片１５の起立部１６を位置させるときと、外側に位置させるときとがあり、内側に位置させる場合がこの発明に係わりがある。このとき、起立部１６が中空踏板部１１，１１の外側面に近接するものの、突起条６と線接触するために密着することがなく、そのために摺動に抵抗となる面接触になるというような強い摩擦が生じないので、接触が強固であっても金属音が発生することはない。 As for the protruding strip 21, there are a case where the upright portion 16 of the L-shaped piece 15 is positioned inside and a case where it is positioned outside, and the case where it is positioned inside relates to the present invention. At this time, the upright portion 16 is close to the outer surface of the hollow tread portions 11 and 11, but does not come into close contact with the protrusion 6 so that it comes into surface contact that resists sliding. Since no strong friction is generated, no metallic noise is generated even if the contact is strong.

排水溝１７は、Ｌ字形片１５の起立部１６と中空踏板部１１との間で幅広く形成されるが、デッキ材５，５，・・が根太３の上に配列して止められると、カバー片１９が排水溝１７に上から入り込んでいることによって、足がつまずかないように受入口２２が狭くなる。このように幅広い排水溝１７を構成するＬ字形片１５が面接触すると、本来は金属音の発生の原因となる振動を起こしやすいが、突起条６との線接触となるので振動が発生しない。 The drainage groove 17 is formed widely between the upright part 16 of the L-shaped piece 15 and the hollow tread part 11, but when the deck members 5, 5,. Since the piece 19 enters the drainage groove 17 from above, the receiving port 22 becomes narrow so that the foot does not trip. Thus, when the L-shaped piece 15 constituting the wide drainage groove 17 is in surface contact, it tends to cause vibration that would otherwise cause the generation of metal sound, but it does not generate vibration because it is in line contact with the protrusion 6.

排水溝１７は見かけの受入口２２により狭いので、広い割りにはつまずくおそれがないが、さらにつまずく不都合を防止するために、受入口２２の縁に相当するカバー片１９の曲がり箇所と、中空踏板部１１の角部に斜面２３，２３が形成される。なお、両中空踏板部１１，１１の間の間隔１３も排水溝となり得るが、ビス７の孔からの漏水があるので、ここには図示しないキャップを嵌めて塞がれる。また、排水溝１７の底部において中空踏板部１１の側面下端にその底面と面一となるよう凹み２５が設けられる。この凹み２５は排水量の拡大となるが、次の実施形態（図３）では別の用途に利用される。 Since the drainage groove 17 is narrower than the apparent receiving port 22, there is no risk of tripping over a wide portion, but in order to prevent further inconvenience, the bent portion of the cover piece 19 corresponding to the edge of the receiving port 22 and the hollow tread Slopes 23, 23 are formed at the corners of the part 11. In addition, although the space | interval 13 between both the hollow tread portions 11 and 11 can also become a drainage groove, since there is water leakage from the hole of the screw 7, a cap (not shown) is fitted and closed here. In addition, a recess 25 is provided at the bottom of the drainage groove 17 so as to be flush with the bottom of the bottom of the side surface of the hollow tread portion 11. Although this dent 25 increases the amount of drainage, it will be used for another purpose in the next embodiment (FIG. 3).

図３は、デッキ材５がプラスチックの被覆材２０との複合となっている場合を示したもので、デッキ材５が根太３や隣接デッキ材５と金属どうしの接触をしないように、下面とＬ字形片１５とにわたってプラスチックで押出成形された被覆材２０で被覆される。この形態において、Ｌ字形片１５を被覆材２０が全面被覆しているが、剥離しないように先端が前記した凹み２５に掛止される。また、起立部１６が被覆材２０で全面被覆されているので、排水溝１７が全面開口の箇所においても（図３の右端）、足に起立部１６が直接触れなく安全である。 FIG. 3 shows a case in which the deck material 5 is a composite with a plastic covering material 20, and the bottom surface of the deck material 5 is set so that the deck material 5 and the adjacent deck material 5 do not contact each other with metal. The L-shaped piece 15 is covered with a covering material 20 extruded with plastic. In this embodiment, the covering material 20 covers the entire surface of the L-shaped piece 15, but the tip is hooked on the recess 25 described above so as not to peel off. Further, since the standing portion 16 is entirely covered with the covering material 20, even when the drainage groove 17 is a full opening portion (right end in FIG. 3), the standing portion 16 is not in direct contact with the foot and is safe.
