本発明は、住宅の床などに用いられる押出成形セメント板床材の取付金具とそれを用いた床材取付構造に関する。 The present invention relates to a mounting bracket for an extruded cement board flooring material used for a floor of a house or the like, and a flooring material mounting structure using the same.

従来、鉄骨系の集合住宅の床材として押出成形セメント板の床材が用いられている。このような床材は、住宅の構造部材である梁材の上に載せられ、金具によって梁材に留め付けられている。押出成形セメント板床材を梁材に留め付ける方法として、梁材に載せた押出成形セメント板床材を階下から留め付け金具で留め付ける方法がある。しかし、この場合には押出成形セメント板床材の施工と金具の取り付けが階下のフロアからの作業となるため作業性が悪くなる。しかも、階下から作業を行う場合、作業員が上向きに見上げた作業となって作業負荷が大きく、脚立などを乗り降りする作業が必要となり、作業効率が悪い。 Conventionally, extruded cement board flooring materials have been used as flooring materials for steel-framed apartments. Such a floor material is placed on a beam material which is a structural member of a house, and is fastened to the beam material by metal fittings. As a method of fastening the extruded cement board floor material to the beam material, there is a method of fastening the extruded cement board floor material placed on the beam material from downstairs with a fastener. However, in this case, the workability is deteriorated because the construction of the extruded cement board floor material and the attachment of the metal fittings are performed from the floor downstairs. Moreover, when the work is performed from downstairs, the work is carried out by the worker looking up upward, and the work load is heavy, and the work of getting on and off the stepladder or the like is required, resulting in poor work efficiency.

そこで、押出成形セメント板床材を施工階において取り付けができるようにした先行技術がある。例えば、押出成形セメント板床材の裏面に可撓部材でＺ型クリップ材を取り付け、このＺ型クリップ材によって押出成形セメント板床材を梁材に挟持する取り付け金具がある（例えば、特許文献１参照）。この金具では、押出成形セメント板床材を梁材に載せた後、押出成形セメント板床材の上方から押出成形セメント板床材の裏面に取り付けられたＺ型クリップ材の先端を押出成形セメント板床材の裏面の方向に回動させることで、押出成形セメント板床材とＺ型クリップ材とによって梁材を挟持している。 Therefore, there is a prior art that enables the extruded cement board flooring material to be attached on the construction floor. For example, there is a mounting bracket in which a Z-shaped clip material is attached to the back surface of an extruded cement board floor material with a flexible member, and the extruded cement board floor material is sandwiched between beam materials by this Z-shaped clip material (see, for example, Patent Document 1). .. In this metal fitting, after the extruded cement board floor material is placed on the beam material, the tip of the Z-shaped clip material attached to the back surface of the extruded cement board floor material from above the extruded cement board floor material is the back surface of the extruded cement board floor material. The beam material is sandwiched between the extruded cement board floor material and the Z-shaped clip material by rotating in the direction of.

また、他の先行技術として、梁材の幅方向中央部分に金具を固定し、金具の左右位置に載せられた押出成形セメント板床材の中空部に留め付け金物を挿入し、押出成形セメント板床材を上方から留め付け金物で梁材に押圧して留め付けけるものもある（例えば、特許文献２参照）。 In addition, as another prior art, a metal fitting is fixed to the central portion in the width direction of the beam material, and a fastener is inserted into the hollow portion of the extruded cement board floor material placed at the left and right positions of the metal fitting, and the extruded cement board floor material is inserted. Can be fastened by pressing it against the beam material with a clasp from above (see, for example, Patent Document 2).

このように構成すれば、本体部の段部によって押出成形セメント板床材を保持する部分と梁材との間に空隙部が形成されるので、押出成形セメント板床材の振動が梁材取付金具から梁材に伝搬することを抑える緩衝特性を発揮することができる。よって、梁材に伝わる振動を抑えることができ、遮音性の向上を図ることができる。 With this configuration, a gap is formed between the portion that holds the extruded cement board floor material and the beam material by the stepped portion of the main body, so that the vibration of the extruded cement board floor material is generated from the beam material mounting bracket. It is possible to exhibit a cushioning property that suppresses propagation to the beam material. Therefore, the vibration transmitted to the beam material can be suppressed, and the sound insulation can be improved.

また、前記掛け止め部は、前記本体部から斜め下方に延びる傾斜部と、前記傾斜部に連続し前記フランジ部と水平に接触する水平部と、前記水平部に連続し前記フランジ部の端部を保持する端部保持部と、を有していてもよい。 Further, the hooking portion includes an inclined portion extending diagonally downward from the main body portion, a horizontal portion continuous with the inclined portion and in horizontal contact with the flange portion, and an end portion of the flange portion continuous with the horizontal portion. It may have an end holding part which holds.

このように構成すれば、掛け止め部の水平部に連続する端部保持部によりフランジ部の端部を保持できるとともに、傾斜部により梁材との間に空隙部ができるので、押出成形セメント板床材の振動が掛け止め部から梁材に伝搬することを抑える緩衝特性を発揮することができる。 With this configuration, the end portion of the flange portion can be held by the end holding portion continuous with the horizontal portion of the hooking portion, and the inclined portion creates a gap between the beam material and the extruded cement board floor. It is possible to exhibit a cushioning property that suppresses the vibration of the material from propagating from the hooking portion to the beam material.

また、前記掛け止め部は、端部保持部の中央部に、上方に折り返した折り返し部をさらに有していてもよい。 Further, the hooking portion may further have a folded-back portion that is folded upward at the central portion of the end holding portion.

このように構成すれば、掛け止め部に抜ける方向の力が掛かった場合、折り返し部が上向きに変形してフランジ部と床材の間で干渉することで、端部保持部がフランジ部から外れにくくなり、梁材取付金具が抜けにくくなる効果を発揮することができる。 With this configuration, when a force is applied to the hooking portion in the pulling direction, the folded-back portion deforms upward and interferes between the flange portion and the floor material, so that the end holding portion comes off from the flange portion. It becomes difficult, and the effect of making it difficult for the beam member mounting bracket to come off can be exhibited.

また、前記挟持部は、前記梁材に設けられた被係合部に係合する係合部をさらに有していてもよい。この明細書及び特許請求の範囲の書類中における「被係合部」は、凹部、凸部及び貫通孔などを含む。「係合部」は、被係合部に係合する凸部、凹凸部、貫通孔などを含む。 Further, the sandwiching portion may further have an engaging portion that engages with the engaged portion provided on the beam member. The "engaged portion" in this specification and the documents of the claims includes recesses, protrusions, through holes, and the like. The "engaging portion" includes a convex portion, an uneven portion, a through hole, and the like that engage with the engaged portion.

このように構成すれば、梁材に凹部、凸部及び貫通孔などの被係合部がある場合、挟持部に設けられた係合部を梁材の被係合部に係合させることにより、取付金具を梁材に保持する保持力をさらに強固にできる。 With this configuration, when the beam material has an engaged portion such as a concave portion, a convex portion, and a through hole, the engaging portion provided in the holding portion is engaged with the engaged portion of the beam material. , The holding force for holding the mounting bracket to the beam material can be further strengthened.

床材押圧金具１１は、矩形状の板材で形成されており、中央部分には梁材取付金具１５に設けられた保持部材たるボルト材１８が挿通される貫通孔１２が設けられている。また、床材押圧金具１１の長手方向には、貫通孔１２の両側方に上向きの突条１３が設けられている。板状の床材押圧金具１１に突条１３を設けることで、曲げ強度を向上させている。この例の床材押圧金具１１は、下面が押出成形セメント板床材１の下面側基材１ｃ（図２）を押圧する押圧部となる。 The floor material pressing metal fitting 11 is formed of a rectangular plate material, and a through hole 12 through which a bolt material 18 as a holding member provided in the beam material mounting metal fitting 15 is inserted is provided in the central portion. Further, in the longitudinal direction of the floor material pressing metal fitting 11, upward ridges 13 are provided on both sides of the through hole 12. Bending strength is improved by providing the ridge 13 on the plate-shaped floor material pressing metal fitting 11. The lower surface of the floor material pressing metal fitting 11 of this example is a pressing portion that presses the lower surface side base material 1c (FIG. 2) of the extruded cement board floor material 1.

梁材取付金具１５は、梁材５の上方に配置される平面状の本体部１６と、本体部１６との間で梁材５のフランジ部６（図２）を幅方向の一方から挟み込む挟持部１７と、本体部１６の上方に設けられた保持部たるボルト材１８と、ボルト材１８にねじ込むナット材１９とを有している。挟持部１７は、板材からなる本体部１６の一方に延びる所定位置を下向きに屈曲させ、端部を本体部１６の下方へ向けて延びるように所定位置まで曲げられて形成されている。挟持部１７は、梁材５のフランジ部６（図２）を幅方向の一方から挟み込むように形成されている。 The beam member mounting bracket 15 sandwiches the flange portion 6 (FIG. 2) of the beam member 5 from one side in the width direction between the flat main body portion 16 arranged above the beam member 5 and the main body portion 16. It has a portion 17, a bolt material 18 as a holding portion provided above the main body portion 16, and a nut material 19 screwed into the bolt material 18. The sandwiching portion 17 is formed by bending a predetermined position extending downward to one side of the main body portion 16 made of a plate material and bending the end portion downward to a predetermined position so as to extend downward of the main body portion 16. The sandwiching portion 17 is formed so as to sandwich the flange portion 6 (FIG. 2) of the beam member 5 from one side in the width direction.

また、梁材取付金具１５には、左右方向の一方に延びる上記挟持部１７とは反対方向に延びる掛け止め部２０が備えられている。掛け止め部２０は、挟持部１７でフランジ部６の幅方向を一方から挟持した状態で、フランジ部６の幅方向の他方端部に掛けることができるように形成されている。掛け止め部２０は、本体部１６の上面に接続された支持部２０ａと、支持部２０ａから斜め下方に延びる傾斜部２０ｂと、傾斜部２０ｂに連続してフランジ部６（図２）に水平に接触する水平部２０ｃと、水平部２０ｃに連続してフランジ部６の端部に掛けられる端部保持部２０ｄと、を有している。端部保持部２０ｄは、板材の端部を下向きに屈曲させて形成されている。端部保持部２０ｄは、水平部２０ｃに対し、３０°〜９０°の角度θの範囲で屈曲するように形成される。端部保持部２０ｄを屈曲させる角度θは、９０°より大きいとフランジ部６に掛け止める効果がなく、３０°より小さいとフランジ部６の端部への掛かりが少なくなり、掛け止め効果が小さくなる。 Further, the beam member mounting bracket 15 is provided with a hooking portion 20 extending in a direction opposite to the holding portion 17 extending in one direction in the left-right direction. The hooking portion 20 is formed so that it can be hung on the other end portion of the flange portion 6 in the width direction while the holding portion 17 sandwiches the width direction of the flange portion 6 from one side. The hooking portion 20 has a support portion 20a connected to the upper surface of the main body portion 16, an inclined portion 20b extending diagonally downward from the supporting portion 20a, and a flange portion 6 (FIG. 2) horizontally continuous with the inclined portion 20b. It has a horizontal portion 20c that comes into contact with the horizontal portion 20c, and an end portion holding portion 20d that is continuously hung on the end portion of the flange portion 6 on the horizontal portion 20c. The end holding portion 20d is formed by bending the end portion of the plate material downward. The end holding portion 20d is formed so as to bend with respect to the horizontal portion 20c in a range of an angle θ of 30 ° to 90 °. If the angle θ at which the end holding portion 20d is bent is larger than 90 °, there is no effect of hooking on the flange portion 6, and if it is smaller than 30 °, the hooking on the end of the flange portion 6 is reduced and the hooking effect is small. Become.

また、この例では、端部保持部２０ｄの中央部に、上方に折り返した折り返し部２０ｅが設けられている。折り返し部２０ｅを設けることにより、梁材取付金具１５が抜ける方向に力が掛かった場合に折り返し部２０ｅが上向きに変形し、フランジ部６と押出成形セメント板床材１の間で干渉することで、端部保持部２０ｄをフランジ部から外れにくくし、梁材取付金具１５を抜けにくくしている。掛け止め部２０は、支持部２０ａが本体部１６に溶接などで接続（固定）される。 Further, in this example, a folded portion 20e folded upward is provided at the central portion of the end holding portion 20d. By providing the folded-back portion 20e, when a force is applied in the direction in which the beam member mounting bracket 15 is pulled out, the folded-back portion 20e is deformed upward and interferes between the flange portion 6 and the extruded cement board floor material 1. The end holding portion 20d is hard to come off from the flange portion, and the beam member mounting bracket 15 is hard to come off. In the hooking portion 20, the support portion 20a is connected (fixed) to the main body portion 16 by welding or the like.

梁材取付金具１５は、梁材５のフランジ部６の両端部を挟持部１７と掛け止め部２０とで水平方向に保持することができるので、梁材取付金具１５を梁材５により強固に保持することができる。 Since both ends of the flange portion 6 of the beam member 5 can be held horizontally by the holding portion 17 and the hooking portion 20, the beam member mounting bracket 15 is made stronger by the beam member 5. Can be held.

さらに、第１取付金具１０は、本体部１６の中央部分が梁材５から上方へ離れるように段部１６ａが設けられている。段部１６ａは、本体部１６を上方へ屈曲させることで形成されている。段部１６ａを設けることで、後述するように、本体部１６と梁材５との間に空隙部Ｖ（図２（Ｂ））が形成される。空隙部Ｖを形成することで、押出成形セメント板床材１の振動が第１取付金具１０から梁材５に伝搬することを抑える緩衝特性を発揮することができる。すなわち、段部１６ａによって振動伝搬に対して緩衝特性を持たせることができるため、第１取付金具１０から梁材５に伝わる振動を抑えることができる。なお、段部１６ａの構成は限定されるものではなく、本体部１６と梁材５との間に空隙部Ｖが形成できる構成であればよい。 Further, the first mounting bracket 10 is provided with a step portion 16a so that the central portion of the main body portion 16 is separated upward from the beam member 5. The step portion 16a is formed by bending the main body portion 16 upward. By providing the step portion 16a, a gap portion V (FIG. 2B) is formed between the main body portion 16 and the beam member 5 as described later. By forming the gap portion V, it is possible to exhibit a cushioning property that suppresses the vibration of the extruded cement board floor material 1 from propagating from the first mounting bracket 10 to the beam material 5. That is, since the step portion 16a can provide a cushioning characteristic against vibration propagation, it is possible to suppress the vibration transmitted from the first mounting bracket 10 to the beam member 5. The configuration of the step portion 16a is not limited as long as it can form a gap portion V between the main body portion 16 and the beam member 5.

図２は、図１に示す第１取付金具１０を梁材５に取り付けた使用状態の図面であり、（Ａ）は平面図であり、（Ｂ）は側面視の断面図である。この実施形態の押出成形セメント板床材１は、第１取付金具１０で梁材５に留め付けられる中空部２の位置の上面側基材１ｂの端部に切欠き部１ｄが設けられている。第１取付金具１０の床材押圧金具１１は、隣り合う押出成形セメント板床材１の目地の間から装着して取り付けてもよいが、この実施形態のように、予め押出成形セメント板床材１の上面側基材１ｂに最小限の切欠き部１ｄを設けることで、より容易に床材押圧金具１１を取り付けることが可能となる。なお、押出成形セメント板床材１が隣り合う場合は、切欠き部１ｄを向い合う押出成形セメント板床材１の端部にそれぞれ設けてもよいし、いずれか一方にのみ設けてもよい。切欠き部１ｄは、床材押圧金具１１が挿入できる大きさであればよい。 (Example of using the first mounting bracket)
2A and 2B are drawings in a used state in which the first mounting bracket 10 shown in FIG. 1 is attached to the beam member 5, FIG. 2A is a plan view, and FIG. 2B is a cross-sectional view in a side view. The extruded cement board floor material 1 of this embodiment is provided with a notch 1d at the end of the upper surface side base material 1b at the position of the hollow portion 2 to be fastened to the beam member 5 by the first mounting bracket 10. The floor material pressing metal fitting 11 of the first mounting metal fitting 10 may be mounted and mounted from between the joints of the adjacent extruded cement board floor material 1, but as in this embodiment, the extruded cement board floor material 1 may be mounted in advance. By providing the minimum cutout portion 1d on the upper surface side base material 1b, the floor material pressing metal fitting 11 can be attached more easily. When the extruded cement board flooring materials 1 are adjacent to each other, the notch portions 1d may be provided at the ends of the extruded cement board flooring materials 1 facing each other, or may be provided only on one of them. The notch portion 1d may have a size that allows the floor material pressing metal fitting 11 to be inserted.

第１取付金具１０によって押出成形セメント板床材１を梁材５へ留め付ける場合、梁材取付金具１５が挟持部１７で梁材５のフランジ部６を幅方向の一方から挟み込むように挿入され、掛け止め部２０の端部保持部２０ｄがフランジ部６の幅方向の他方端部に掛けられて梁材５の所定位置に取り付けられる。この状態の梁材取付金具１５は、挟持部１７と端部保持部２０ｄとによってフランジ部６を水平方向に保持しているので、強い保持力で保持されている。 When the extruded cement board floor material 1 is fastened to the beam material 5 by the first mounting bracket 10, the beam material mounting bracket 15 is inserted so as to sandwich the flange portion 6 of the beam material 5 with the sandwiching portion 17 from one side in the width direction. The end holding portion 20d of the hooking portion 20 is hung on the other end portion in the width direction of the flange portion 6 and attached to a predetermined position of the beam member 5. Since the flange portion 6 is held in the horizontal direction by the holding portion 17 and the end holding portion 20d, the beam member mounting bracket 15 in this state is held with a strong holding force.

その後、梁材取付金具１５の本体部１６に設けられたボルト材１８を挟んで、押出成形セメント板床材１が梁材５に載せられる。梁材取付金具１５が強い保持力で梁材５に取り付けられているので、押出成形セメント板床材１を容易に載せることができる。そして、ボルト材１８に、床材押圧金具１１が貫通孔１２から挿入される。そして、ボルト材１８にナット材１９をねじ込んで締め付けることで、床材押圧金具１１によって押出成形セメント板床材１の下面側基材１ｃが梁材５に向けて押圧されて保持される。これにより、隣り合う押出成形セメント板床材１を梁材５に留め付けることができる。 After that, the extruded cement board floor material 1 is placed on the beam material 5 with the bolt material 18 provided on the main body 16 of the beam material mounting bracket 15 sandwiched. Since the beam material mounting bracket 15 is attached to the beam material 5 with a strong holding force, the extruded cement board floor material 1 can be easily mounted. Then, the floor material pressing metal fitting 11 is inserted into the bolt material 18 through the through hole 12. Then, by screwing and tightening the nut material 19 into the bolt material 18, the lower surface side base material 1c of the extruded cement board floor material 1 is pressed and held toward the beam material 5 by the floor material pressing metal fitting 11. As a result, the adjacent extruded cement board floor material 1 can be fastened to the beam material 5.

また、第１取付金具１０は、部品数を少なくすることができる。その上、押出成形セメント板床材１を施工階において上方から下向き作業で梁材５に留め付けることができるので、施工性を向上させることができる。しかも、空隙部Ｖにより、押出成形セメント板床材１から梁材５に向けて振動が伝搬することを抑える緩衝特性を発揮することができる。よって、梁材５に伝わる振動を抑えることができ、遮音性が向上する。 Further, the number of parts of the first mounting bracket 10 can be reduced. Further, since the extruded cement board floor material 1 can be fastened to the beam material 5 from above on the construction floor by downward work, the workability can be improved. Moreover, the gap portion V can exhibit a cushioning property that suppresses the propagation of vibration from the extruded cement board floor material 1 to the beam material 5. Therefore, the vibration transmitted to the beam member 5 can be suppressed, and the sound insulation property is improved.

さらに、第１取付金具１０は、梁材５の左右位置に載せられる隣り合う押出成形セメント板床材１を１つの床材押圧金具１１で同時に押圧して留め付けることができる。このため、隣り合う押出成形セメント板床材１の留め付け作業を１箇所で行うことができ、押出成形セメント板床材１の留め付け作業を効率良く行うことができる。 Further, the first mounting bracket 10 can simultaneously press and fasten the adjacent extruded cement board flooring materials 1 placed on the left and right positions of the beam member 5 with one flooring material pressing metal fitting 11. Therefore, the fastening work of the adjacent extruded cement board flooring materials 1 can be performed at one place, and the fastening work of the extruded cement board flooring material 1 can be efficiently performed.

The extruded cement board floor material 1 of this embodiment also has a notch 1d at the end of the upper surface side base material 1b of the portion to be fastened to the beam material 5 by the third mounting bracket 50.

第３取付金具５０によって押出成形セメント板床材１を梁材５へ取り付ける場合、梁材取付金具５５が挟持部５７で梁材５のフランジ部６を幅方向の一方から挟み込むように挿入され、掛け止め部６０の端部保持部６０ｄがフランジ部６の幅方向の他方端部に掛けられて梁材５の所定位置に取り付けられる。その後、押出成形セメント板床材１が、梁材取付金具５５の本体部５６に設けられたボルト材５８に近接するように梁材５に載せられる。そして、押出成形セメント板床材１の中空部２に床材押圧金具５１が入れられて、ピン５２が貫通孔８に挿入されて係止され、貫通孔５３ａがボルト材５８に挿通される。その後、ボルト材５８にナット材５９をねじ込んで締め付けることで、支持部５４がボルト材５８に沿った状態で、床材押圧金具５１によって押出成形セメント板床材１の下面側基材１ｃが梁材５に向けて押圧される。これにより、押出成形セメント板床材１を梁材５に留め付けることができる。 When the extruded cement board floor material 1 is attached to the beam material 5 by the third mounting bracket 50, the beam material mounting bracket 55 is inserted so as to sandwich the flange portion 6 of the beam material 5 from one side in the width direction by the holding portion 57, and is hooked. The end holding portion 60d of the stop portion 60 is hung on the other end portion of the flange portion 6 in the width direction and attached to a predetermined position of the beam member 5. After that, the extruded cement board floor material 1 is placed on the beam material 5 so as to be close to the bolt material 58 provided in the main body portion 56 of the beam material mounting bracket 55. Then, the floor material pressing metal fitting 51 is inserted into the hollow portion 2 of the extruded cement board floor material 1, the pin 52 is inserted into the through hole 8 and locked, and the through hole 53a is inserted into the bolt material 58. After that, the nut material 59 is screwed into the bolt material 58 and tightened, so that the lower surface side base material 1c of the extruded cement board floor material 1 is a beam material by the floor material pressing metal fitting 51 with the support portion 54 along the bolt material 58.

このように、床材押圧金具５１を、平板状の板状部５３と端部が下向きに折れ曲がった支持部５４とを有する形状とすることで、施工階の端部において梁材５の片側に押出成形セメント板床材１を配置する場合でも、凹み部５４ａがボルト材５８に接して床材押圧金具５１の水平状態を維持できる。よって、押出成形セメント板床材１を梁材５に向けて押圧して留め付けることができる。 In this way, the floor material pressing metal fitting 51 has a shape having a flat plate-shaped portion 53 and a support portion 54 whose end is bent downward, so that the floor material pressing metal fitting 51 can be placed on one side of the beam member 5 at the end of the construction floor. Even when the extruded cement board floor material 1 is arranged, the recessed portion 54a can be in contact with the bolt material 58 to maintain the horizontal state of the floor material pressing metal fitting 51. Therefore, the extruded cement board floor material 1 can be pressed and fastened toward the beam material 5.

また、第３取付金具５０によれば、床材押圧金具５１のピン５２を下面側基材１ｃの貫通孔８に係止した状態で留め付けるので、床材押圧金具５１の位置を保った状態で押出成形セメント板床材１の留め付けを強固に行うことができる。 Further, according to the third mounting bracket 50, the pin 52 of the floor material pressing bracket 51 is fastened in a state of being locked to the through hole 8 of the lower surface side base material 1c, so that the position of the floor material pressing bracket 51 is maintained. The extrusion-molded cement board floor material 1 can be firmly fastened.

さらに、第３取付金具５０によっても、部品数を少なくすることができる。その上、押出成形セメント板床材１を施工階において上方から下向き作業で梁材５に留め付けることができるので、施工性を向上させることができる。しかも、空隙部Ｖにより、押出成形セメント板床材１から梁材５に向けて振動が伝搬することを抑える緩衝特性を発揮することができる。よって、梁材５に伝わる振動を抑えることができ、遮音性が向上する。 Further, the number of parts can be reduced by the third mounting bracket 50. Further, since the extruded cement board floor material 1 can be fastened to the beam material 5 from above on the construction floor by downward work, the workability can be improved. Moreover, the gap portion V can exhibit a cushioning property that suppresses the propagation of vibration from the extruded cement board floor material 1 to the beam material 5. Therefore, the vibration transmitted to the beam member 5 can be suppressed, and the sound insulation property is improved.

Further, the main body portion 126 of this example is provided with an engaging portion 126b for engaging with the engaged portion 7 provided on the flange portion 6 of the beam member 5 at the portion of the holding portion 127.

中空部保持部１２８は、本体部１２６の上面に設けられた所定高さの台座１２９と、台座１２９の上部に設けられた回転防止部材１３０と、回転防止部材１３０の上方に設けられた押圧部材１３１とを有している。台座１２９は、本体部１２６から前後方向の一方（この例では前方（図２５））に片寄って、所定高さで立ち上がるように設けられている。台座１２９の上面１２９ａには、ボルト１３２をねじ込むボルト孔１２９ｂが設けられている。台座１２９の高さは、床材取付金具１２１の立ち上がり部１２４を押圧できる高さに設定されている（図２３（Ｂ））。なお、台座１２９は、本体部１２６の前後方向の中央部分で立ち上がるようにしてもよい。回転防止部材１３０には、爪部１３０ａが上向きに突設されており、台座１２９のボルト孔１２９ｂの部分に貫通孔１３０ｂが設けられている。回転防止部材１３０は、押圧部材１３１が押出成形セメント板床材１の端縁と平行となる状態に回転した退避状態で押圧部材１３１を係止する。 The hollow portion holding portion 128 includes a pedestal 129 having a predetermined height provided on the upper surface of the main body 126, an anti-rotation member 130 provided on the upper portion of the pedestal 129, and a pressing member provided above the anti-rotation member 130. It has 131 and. The pedestal 129 is provided so as to stand up at a predetermined height from the main body 126 in one of the front-rear directions (in this example, the front (FIG. 25)). The upper surface 129a of the pedestal 129 is provided with a bolt hole 129b into which the bolt 132 is screwed. The height of the pedestal 129 is set to a height at which the rising portion 124 of the floor material mounting bracket 121 can be pressed (FIG. 23 (B)). The pedestal 129 may stand up at the central portion of the main body 126 in the front-rear direction. The rotation prevention member 130 has a claw portion 130a projecting upward, and a through hole 130b is provided in a portion of the bolt hole 129b of the pedestal 129. The rotation prevention member 130 locks the pressing member 131 in a retracted state in which the pressing member 131 is rotated so as to be parallel to the edge of the extruded cement board floor material 1.

押圧部材１３１は、回転軸たるボルト１３２が所定位置に挿通されており、ボルト１３２を中心に回転可能となっている。ボルト１３２は、例えば六角穴付ボルトを用いることができる。押圧部材１３１は、ボルト１３２が挿通された支持部１３１ｂの両端部に、床材取付金具１２１の立ち上がり部１２４を押し付けるように下向きに屈曲された押付部１３１ｃが設けられている。押圧部材１３１の支持部１３１ｂには、回転防止部材１３０の爪部１３０ａに当接する凹部１３１ａが設けられている。押圧部材１３１は、回転軸たるボルト１３２を中心に、床材取付金具１２１の立ち上がり部１２４を押圧して押出成形セメント板床材１を梁材５に押し付ける配置状態と、押出成形セメント板床材１の中空部２から出た退避状態と、に回転する。 A bolt 132, which is a rotation shaft, is inserted into the pressing member 131 at a predetermined position, and the pressing member 131 can rotate around the bolt 132. As the bolt 132, for example, a hexagon socket head cap screw can be used. The pressing member 131 is provided with pressing portions 131c bent downward so as to press the rising portion 124 of the floor material mounting bracket 121 at both ends of the support portion 131b through which the bolt 132 is inserted. The support portion 131b of the pressing member 131 is provided with a recess 131a that abuts on the claw portion 130a of the rotation prevention member 130. The pressing member 131 is arranged so that the extruded cement plate floor material 1 is pressed against the beam material 5 by pressing the rising portion 124 of the floor material mounting bracket 121 around the bolt 132 which is the rotation shaft, and the extruded cement plate floor material 1. It rotates to the retracted state from the hollow portion 2.

ボルト１３２には、押圧部材１３１の下面に当接するバネ部材１３３が設けられている。ボルト１３２を台座１２９のボルト孔１２９ｂにねじ込むことで、押圧部材１３１はバネ部材１３３によってボルト１３２の頭部１３２ａに向けて付勢される。押圧部材１３１は、バネ部材１３３により、ボルト１３２の下端部を台座１２９のボルト孔１２９ｂにねじ込んだ取付状態では、頭部１３２ａに当接して押出成形セメント板床材１の中空部２に向けて回転させることができる高さで保持される。 The bolt 132 is provided with a spring member 133 that comes into contact with the lower surface of the pressing member 131. By screwing the bolt 132 into the bolt hole 129b of the pedestal 129, the pressing member 131 is urged by the spring member 133 toward the head 132a of the bolt 132. The pressing member 131 abuts on the head 132a and rotates toward the hollow portion 2 of the extruded cement board floor material 1 in the mounted state in which the lower end of the bolt 132 is screwed into the bolt hole 129b of the pedestal 129 by the spring member 133. It is held at a height that allows it to be made.

さらに、第７取付金具１２０は、本体部１２６が挟持部１２７に対して上方に離れるように段部１２６ａが設けられている。段部１２６ａは、本体部１２６と挟持部１２７との間を上方へ屈曲させることで形成されている。段部１２６ａを設けることで、後述するように、本体部１２６と梁材５との間に空隙部Ｖ（図２３（Ｂ））が形成される。空隙部Ｖを形成することで、押出成形セメント板床材１の振動が第７取付金具１２０から梁材５に伝搬することを抑える緩衝特性を発揮することができる。すなわち、段部１２６ａによって振動伝搬に対して緩衝特性を持たせることができるため、第７取付金具１２０から梁材５に伝わる振動を抑えることができる。 Further, the seventh mounting bracket 120 is provided with a step portion 126a so that the main body portion 126 is separated upward from the holding portion 127. The step portion 126a is formed by bending upward between the main body portion 126 and the sandwiching portion 127. By providing the step portion 126a, a gap portion V (FIG. 23 (B)) is formed between the main body portion 126 and the beam member 5 as described later. By forming the gap portion V, it is possible to exhibit a cushioning property that suppresses the vibration of the extruded cement board floor material 1 from propagating from the seventh mounting bracket 120 to the beam material 5. That is, since the step portion 126a can provide a cushioning property against vibration propagation, the vibration transmitted from the seventh mounting bracket 120 to the beam member 5 can be suppressed.

床材取付金具１２１は、１つの梁材取付金具１２５に対して対向する位置に一対が設けられる。一対の床材取付金具１２１の立ち上がり部１２４を、梁材取付金具１２５の押圧部材１３１で同時に押圧して押出成形セメント板床材１を梁材５に留め付ける。 A pair of floor material mounting brackets 121 are provided at positions facing one beam mounting bracket 125. The rising portion 124 of the pair of floor material mounting brackets 121 is simultaneously pressed by the pressing member 131 of the beam material mounting bracket 125 to fasten the extruded cement board floor material 1 to the beam material 5.

押圧部材１３１は、ボルト１３２を締める方向に回転させることにより、回転防止部材１３０の爪部１３０ａに係止されて止まる（図２３（Ａ））。この状態が、押圧部材１３１の配置状態であり、押圧部材１３１で床材取付金具１２１の立ち上がり部１２４を押圧することができる。また、押圧部材１３１は、ボルト１３２を緩める方向に回転させることにより、押出成形セメント板床材１の中空部２から出て回転防止部材１３０の爪部１３０ａに係止されて止まる。この状態が、押圧部材１３１の退避状態である（後述する図２７と同様）。 By rotating the pressing member 131 in the direction of tightening the bolt 132, the pressing member 131 is locked to the claw portion 130a of the rotation prevention member 130 and stops (FIG. 23 (A)). This state is the arrangement state of the pressing member 131, and the pressing member 131 can press the rising portion 124 of the floor material mounting bracket 121. Further, by rotating the pressing member 131 in the direction of loosening the bolt 132, the pressing member 131 comes out of the hollow portion 2 of the extruded cement board floor material 1 and is locked to the claw portion 130a of the rotation prevention member 130 to stop. This state is the retracted state of the pressing member 131 (similar to FIG. 27 described later).

この第７取付金具１２０によれば、押圧部材１３１は回転防止部材１３０によって、退避状態では押出成形セメント板床材１の端縁と平行の状態で係止され、配置状態では押出成形セメント板床材１の中空部２が延びる方向に向けられた状態で係止され、退避状態と配置状態の適切な位置で止まるようになっている。これにより、押出成形セメント板床材１の取付作業を効率良く行うことができる。 According to the seventh mounting bracket 120, the pressing member 131 is locked by the rotation prevention member 130 in a state parallel to the edge of the extruded cement board floor material 1 in the retracted state, and is locked in the extruded cement board floor material 1 in the arranged state. The hollow portion 2 of the above is locked in a state of being directed in the extending direction, and stops at appropriate positions in the retracted state and the arranged state. As a result, the mounting work of the extruded cement board floor material 1 can be efficiently performed.

そして、押圧部材１３１は、配置状態においてボルト１３２を締め付けることでバネ部材１３３が圧縮されて床材取付金具１２１の立ち上がり部１２４を梁材５に向けて押圧する。これにより、床材取付金具１２１で押出成形セメント板床材１を梁材５に押し付けて留め付けることができる。 Then, the pressing member 131 compresses the spring member 133 by tightening the bolt 132 in the arranged state, and presses the rising portion 124 of the floor material mounting bracket 121 toward the beam member 5. As a result, the extruded cement board floor material 1 can be pressed and fastened to the beam material 5 by the floor material mounting bracket 121.

（第７取付金具の使用例）
図２３は、図２２に示す第７取付金具１２０を梁材５に取り付けた使用状態を示す図面であり、（Ａ）は（Ｂ）に示すXXIII−XXIII矢視の断面図であり、（Ｂ）は側面視の断面図である。 (Example of using the 7th mounting bracket)
FIG. 23 is a drawing showing a usage state in which the seventh mounting bracket 120 shown in FIG. 22 is attached to the beam member 5, and FIG. 23A is a cross-sectional view taken along the line XXIII-XXIII shown in FIG. 22B. ) Is a cross-sectional view of the side view.

第７取付金具１２０によれば、梁材５の上に緩衝材４が置かれ、その上に押出成形セメント板床材１が載せられる。そして、梁材取付金具１２５が挟持部１２７で梁材５のフランジ部６を幅方向の一方から挟み込むように取り付けられる。梁材取付金具１２５の梁材５への取り付けは、押出成形セメント板床材１を載せる前、一方の押出成形セメント板床材１を載せた後のいずれでもよい。押出成形セメント板床材１を載せた後でも、押出成形セメント板床材１の前後方向の中間部分には、緩衝材４の継目の部分に緩衝材４の厚み分の空間Ｓができる。このため、この空間Ｓを利用して、梁材取付金具１２５の本体部１２６を挿入して取り付けることができる。この場合、梁材取付金具１２５の取り付け後、押圧部材１３１を中空部２の延びる方向と直交する方向に向けておくとよい。また、押出成形セメント板床材１の中空部２に、床材取付金具１２１が挿入されてピン１２２が貫通孔３に係止される。 According to the seventh mounting bracket 120, the cushioning material 4 is placed on the beam material 5, and the extruded cement board floor material 1 is placed on the cushioning material 4. Then, the beam member mounting bracket 125 is attached so as to sandwich the flange portion 6 of the beam member 5 from one side in the width direction by the sandwiching portion 127. The beam material mounting bracket 125 may be attached to the beam material 5 either before the extruded cement board floor material 1 is placed or after one of the extruded cement board floor materials 1 is placed. Even after the extruded cement board floor material 1 is placed, a space S corresponding to the thickness of the cushioning material 4 is formed at the joint portion of the cushioning material 4 in the intermediate portion in the front-rear direction of the extruded cement board floor material 1. Therefore, the main body 126 of the beam member mounting bracket 125 can be inserted and mounted using this space S. In this case, after mounting the beam member mounting bracket 125, the pressing member 131 may be oriented in a direction orthogonal to the extending direction of the hollow portion 2. Further, the floor material mounting bracket 121 is inserted into the hollow portion 2 of the extruded cement board floor material 1, and the pin 122 is locked in the through hole 3.

この第７取付金具１２０によれば、梁材５に取り付けた梁材取付金具１２５の左右位置に押出成形セメント板床材１を載せた後、隣り合う押出成形セメント板床材１の目地部Ｍ（図２８（Ｂ）に示す押出成形セメント板床材１の間）からボルト１３２を回転させる。ボルト１３２によって回転させた押圧部材１３１は、押出成形セメント板床材１の中空部２に進入して配置状態になると回転防止部材１３０の爪部１３０ａに当接して止まる（図２３（Ａ））。その後、その状態でボルト１３２をさらにねじ込むことで、押圧部材１３１によって床材取付金具１２１の立ち上がり部１２４を押圧し、これにより押出成形セメント板床材１を梁材５に向けて押し付けて留め付けることができる。 According to the seventh mounting bracket 120, after the extruded cement board floor material 1 is placed at the left and right positions of the beam material mounting bracket 125 attached to the beam material 5, the joint portion M of the adjacent extruded cement board flooring materials 1 (FIG. The bolt 132 is rotated from (between the extruded cement board floor material 1) shown in 28 (B). When the pressing member 131 rotated by the bolt 132 enters the hollow portion 2 of the extruded cement board floor material 1 and is in the arranged state, it comes into contact with the claw portion 130a of the rotation prevention member 130 and stops (FIG. 23 (A)). After that, by further screwing the bolt 132 in that state, the rising portion 124 of the floor material mounting bracket 121 is pressed by the pressing member 131, whereby the extruded cement board floor material 1 is pressed and fastened toward the beam material 5. Can be done.

しかも、第７取付金具１２０は、梁材５の左右位置に載せられる隣り合う押出成形セメント板床材１に設けられている床材取付金具１２１の立ち上がり部１２４を押圧部材１３１で同時に押圧する。このため、隣り合う押出成形セメント板床材１を保持する作業を１箇所で行うことができ、押出成形セメント板床材１の取付作業を効率良く行うことができる。このことは、後述する第８取付金具１４０も同様である。 Moreover, the seventh mounting bracket 120 simultaneously presses the rising portion 124 of the flooring material mounting bracket 121 provided on the adjacent extruded cement plate flooring material 1 placed on the left and right positions of the beam member 5 with the pressing member 131. Therefore, the work of holding the adjacent extruded cement board floor material 1 can be performed at one place, and the work of attaching the extruded cement board floor material 1 can be efficiently performed. This also applies to the eighth mounting bracket 140, which will be described later.

その上、第７取付金具１２０によれば、挟持部１２７で梁材５のフランジ部６を挟持した取付状態で、本体部１２６の段部１２６ａによって梁材５との間に空隙部Ｖが形成される（図２３（Ｂ））。この空隙部Ｖにより、第７取付金具１２０から梁材５に向けて振動が伝搬することを抑える緩衝特性を発揮することができる。よって、梁材５に伝わる振動を抑えることができ、遮音性が向上する。このことは、後述する第８取付金具１４０も同様である。 Further, according to the seventh mounting bracket 120, a gap portion V is formed between the holding portion 127 and the beam member 5 by the stepped portion 126a of the main body portion 126 in the mounting state in which the flange portion 6 of the beam member 5 is sandwiched between the sandwiching portions 127. (Fig. 23 (B)). Due to this gap portion V, it is possible to exhibit a cushioning property that suppresses the propagation of vibration from the seventh mounting bracket 120 toward the beam member 5. Therefore, the vibration transmitted to the beam member 5 can be suppressed, and the sound insulation property is improved. This also applies to the eighth mounting bracket 140, which will be described later.

（第８実施形態に係る第８取付金具）
図２４は、第８実施形態に係る第８取付金具１４０を示す分解斜視図である。第８取付金具１４０は、梁材取付金具１４５の一部と床材取付金具１４１及び押圧部材１５１が第７取付金具１２０とは異なる構成となっている。以下の説明では、第７取付金具１２０と異なる構成についてのみ説明し、同一の構成には「２０」を加えた符号を付して、その説明は省略する。 (8th mounting bracket according to the 8th embodiment)
FIG. 24 is an exploded perspective view showing the eighth mounting bracket 140 according to the eighth embodiment. The eighth mounting bracket 140 has a structure in which a part of the beam mounting bracket 145, the floor material mounting bracket 141, and the pressing member 151 are different from the seventh mounting bracket 120. In the following description, only the configuration different from that of the seventh mounting bracket 120 will be described, and the same configuration will be designated by a reference numeral with “20” added, and the description thereof will be omitted.

第８取付金具１４０の床材取付金具１４１は、押出成形セメント板床材１の被係止部たる貫通孔３（図２３）に係止させる係止部材がボルト１４２となっている。また、床材取付金具１４１の板状部１４３には、ボルト１４２を螺合させるねじ部１４３ａが設けられている。床材取付金具１４１の押出成形セメント板床材１の端縁付近には、上向きに屈曲して立ち上がる立ち上がり部１４４が設けられている。 In the floor material mounting bracket 141 of the eighth mounting bracket 140, the locking member for locking in the through hole 3 (FIG. 23) which is the locked portion of the extruded cement board floor material 1 is a bolt 142. Further, the plate-shaped portion 143 of the floor material mounting bracket 141 is provided with a screw portion 143a for screwing the bolt 142. An extruded cement plate of the floor material mounting bracket 141 A rising portion 144 that bends upward and rises is provided near the edge of the floor material 1.

第８取付金具１４０は、係止部をボルト１４２とすることで、床材取付金具１４１と押出成形セメント板床材１との接合が強固になるので、押出成形セメント板床材１の取り付けもより強固に行うことができる。 In the eighth mounting bracket 140, since the locking portion is a bolt 142, the joint between the floor material mounting bracket 141 and the extruded cement board floor material 1 is strengthened, so that the extruded cement board floor material 1 is also more firmly mounted. Can be done.

また、第８取付金具１４０は、本体部１４６の上面部分に切り欠き部１４６ｃが設けられている。切り欠き部１４６ｃを設けることで、本体部１４６と梁材５とが接触したとしても、音の伝搬を軽減することができる。なお、切り欠き部１４６ｃはなくてもよい。他の構成は第７取付金具１２０と同一であるため、詳細な説明は省略する。 Further, the eighth mounting bracket 140 is provided with a notch portion 146c on the upper surface portion of the main body portion 146. By providing the cutout portion 146c, it is possible to reduce the propagation of sound even if the main body portion 146 and the beam member 5 come into contact with each other. The cutout portion 146c may not be provided. Since other configurations are the same as those of the seventh mounting bracket 120, detailed description thereof will be omitted.

このような第８取付金具１４０によっても、押圧部材１５１は回転防止部材１５０によって、退避状態では押出成形セメント板床材１の端縁と平行の状態で係止され、配置状態では押出成形セメント板床材１の中空部２が延びる方向に向けられた状態で係止され、退避状態と配置状態の適切な位置で止まるようになっている。これにより、押出成形セメント板床材１の取付作業を効率良く行うことができる。 Even with such an eighth mounting bracket 140, the pressing member 151 is locked by the rotation prevention member 150 in a state parallel to the edge of the extruded cement board floor material 1 in the retracted state, and is locked in the extruded cement board floor material 1 in the arranged state. The hollow portion 2 of 1 is locked in a state of being directed in the extending direction, and stops at appropriate positions in the retracted state and the arranged state. As a result, the mounting work of the extruded cement board floor material 1 can be efficiently performed.

そして、中空部保持部１４８の押圧部材１５１を配置状態として、ボルト１５２を締め付けることでバネ部材１５３が圧縮されて床材取付金具１４１の立ち上がり部１４４を梁材５に向けて押圧する。これにより、床材取付金具１４１で押出成形セメント板床材１を梁材５に押し付けて留め付けることができる。 Then, with the pressing member 151 of the hollow portion holding portion 148 in the arranged state, the spring member 153 is compressed by tightening the bolt 152, and the rising portion 144 of the floor material mounting bracket 141 is pressed toward the beam member 5. As a result, the extruded cement board floor material 1 can be pressed and fastened to the beam material 5 by the floor material mounting bracket 141.

（第８取付金具を用いた取付構造例）
図２５は、図２４に示す第８取付金具１４０を梁材５に取り付けた取付構造を示す斜視図である。第８取付金具１４０は、梁材取付金具１４５が挟持部１４７で梁材５のフランジ部６を幅方向の一方から挟み込むように取り付けられる。梁材取付金具１４５の取り付け後、押出成形セメント板床材１を載せる時の障害にならないように押圧部材１５１を中空部２の延びる方向と直交する方向に向けておくとよい。一方、床材取付金具１４１は、予め押出成形セメント板床材１の中空部２に挿入され、押出成形セメント板床材１の貫通孔３の部分にボルト１５２で固定される。 (Example of mounting structure using the 8th mounting bracket)
FIG. 25 is a perspective view showing a mounting structure in which the eighth mounting bracket 140 shown in FIG. 24 is mounted on the beam member 5. The eighth mounting bracket 140 is mounted so that the beam member mounting bracket 145 sandwiches the flange portion 6 of the beam member 5 from one side in the width direction with the holding portion 147. After the beam member mounting bracket 145 is attached, the pressing member 151 may be oriented in a direction orthogonal to the extending direction of the hollow portion 2 so as not to be an obstacle when the extruded cement board flooring material 1 is placed.
