Description

【０００１】
【発明の属する技術分野】
本発明は、上下階の床パネルへの振動の伝達を抑制できると共に、壁パネルの変形等も防止できる壁パネルの取り付け構造に関する。
【０００２】
【従来の技術】
従来、住宅（店舗付き住宅等を含む）を建てる工法としては、木造、鉄筋コンクリート造あるいは鉄骨造があり、特に鉄骨造、とりわけ軽量鉄骨造よりも重量鉄骨造の方が、きわめて強靭な鋼材を素材として骨組みを組み立てる構造であるため、強靭で経済的な住宅を建てることができるという利点があり、近年では最も注目されている。
【０００３】
上記鉄骨造において、図４（Ａ）（Ｂ）に示すように、２階以上の鉄骨２階床梁１の上に床パネル２Ｂをボルト１１で直接固定したり、コンクリート基礎台３の上に床パネル２Ａを直接固定したりすると、歩行振動等が床パネル２Ｂから鉄骨２階床梁１に直接伝わって、鉄骨２階床梁１の微振が続くことにより、階下の天井面から歩行音等が大きく反響するという問題があった。また、鉄骨２階床梁１及びコンクリート基礎台３は硬いことから、歩行中の足腰に負担がかかるという問題もあった。
【０００４】
このため、本出願人は、特願平８−９９１５４号において、住宅等の鉄骨梁１又はコンクリート基礎台３の上に硬質の吸振ゴム４を介して床パネル２Ａ，２Ｂを固定した住宅用床パネルの固定構造を提案した。
これによれば、２階の床パネル２Ｂの歩行振動等は、鉄骨２階床梁１に伝わる前に吸振ゴム４で大幅に吸振されるから、鉄骨２階床梁１の微振が減少して階下の天井面から歩行音等が反響しにくくなる、つまり、吸振ゴム４で吸音されて歩行音等が小さくなると共に、１階のコンクリート基礎台３の上に吸振ゴム４を介して床パネル２Ａを固定しても、吸振ゴム４による吸振・吸音作用により歩行音等が小さくなるという作用・効果を奏することができる。
【０００５】
一方、１階の外壁パネル５Ａは、下框５ｂの段部を１階の床パネル２Ａの端部に嵌め合わせると共に、上框５ａの段部を２階の床パネル２Ｂの端部に嵌め合わせて、各框５ａ，５ｂを木ねじ６で床パネル２Ａ，２Ｂの端部に取り付けている。同様に、２階の外壁パネル５Ｂも、下框５ｂの段部を２階の床パネル２Ｂの段部に嵌め合わせると共に、上框５ａの段部を２階の鉄骨天井梁の上の横木（不図示）の端部に嵌め合わせて、各框５ａ，５ｂを木ねじ６で床パネル２Ｂ及び横木に取り付けている。
【０００６】
【発明が解決しようとする課題】
ところで、図５（Ａ）に示すように、２階の床パネル２Ｂに対する１階の外壁パネル５Ａの取り付け部分では、図５（Ｂ）に示すように、２階の床パネル２Ｂに人や荷物の荷重Ｐが作用して、吸振ゴム４がたわんだとき（例えば、吸振ゴム４の厚みが２５ｍｍであれば、２００Ｋｇ／平方ｃｍの荷重で約２ｍｍのたわみ量）、２階の床パネル２Ｂの上下振動に伴って、木ねじ６で取り付けられた１階の外壁パネル５Ａも上下振動しようとする。
このとき、１階の外壁パネル５Ａの下框５ｂは１階の床パネル２Ａに木ねじ６で取り付けられているから、外壁パネル５Ａ自体が上下振動することができないので、２階の床パネル２Ｂと１階の床パネル２Ａとの間に作用する圧縮力で外壁パネル５Ａが弓なり状に変形するようになる（二点鎖線参照）。
【０００７】
また、１階と２階の床パネル２Ａ，２Ｂに１階の外壁パネル５Ａの下框５ｂと上框５ａが木ねじ６で取り付けられているから、各階の床パネル２Ａ，２Ｂの歩行振動等が１階の外壁パネル５Ａを介して各階の床パネル２Ａ，２Ｂに伝達されやすい。
さらに、各床パネル２Ａ，２Ｂの上下振動に伴って、各床パネル２Ａ，２Ｂ及び横木の端部付近で木ねじ６に剪断力が作用して木ねじ６が剪断されるおそれがあると共に、各外壁パネル５Ａ，５Ｂのねじ穴付近でクラックが発生して、各外壁パネル５Ａ，５Ｂが破損するおそれがある。
【０００８】
本発明は、上記問題を解決するためになされたもので、上下階の床パネルへの振動の伝達を抑制できると共に、壁パネルの変形等も防止できる壁パネルの取り付け構造を提供することを課題とするものである。
【０００９】
【課題を解決するための手段】
上記課題を解決するために、本発明は、住宅等の鉄骨床梁又はコンクリート基礎台の上に硬質の吸振ゴムを介して床パネルを固定すると共に、この床パネルの端部又は鉄骨天井梁の上の横木の端部に、壁パネルの上框と下框の各段部を嵌め合わせて、嵌め合わせた框をねじで床パネル又は横木の端部に取り付ける構造であって、
上記壁パネルの上框と下框の少なくとも一方に、上記ねじよりも大径の嵌合穴をあけると共に、上記ねじに、この嵌合穴に嵌合する硬質の吸振・圧縮力吸収用のゴムスリーブを嵌着していることを特徴とする壁パネルの取り付け構造を提供するものである。
【００１０】
本発明によれば、壁パネルの上框と下框の各段部を床パネル等の端部に嵌め合わせて、嵌め合わせた框をねじで床パネル等の端部に取り付けるときに、上框と下框の少なくとも一方にあけた嵌合穴に、ねじに嵌着した硬質のゴムスリーブを嵌合させる。例えば、２階の床パネルの端部に取り付けた１階の壁パネルの上框に嵌合穴をあけて、この嵌合穴に、ねじに嵌着したゴムスリーブを嵌合させる。なお、壁パネルの上框と下框の両方に嵌合穴をあけて、ねじに嵌着したゴムスリーブを嵌合させるようにしても良い。
【００１１】
これにより、２階の床パネルが上下振動したとき、２階の床パネルに固定されたねじを介して１階の壁パネルも上下振動しようとするが、ねじには吸振・圧縮力吸収作用を有するゴムスリーブが嵌着されているから、２階の床パネルの上下振動がゴムスリーブで吸振されて、１階の壁パネルに伝達されにくくなる。
同様に、１階の床パネルが上下振動したとき、これに伴って１階の壁パネルも上下振動するが、１階の壁パネルの上下振動がゴムスリーブで吸振されて、２階の床パネルに伝達されにくくなる。
これらにより、壁パネルを介して上下階の床パネルへの振動の伝達が抑制されるようになる。
【００１２】
また、２階の床パネルの上下振動がゴムスリーブで吸振されて、１階の壁パネルに伝達されにくくなるから、２階の床パネルの上下振動に伴う圧縮力が１階の壁パネルに作用しないので、１階の壁パネルが変形しなくなる。
さらに、ゴムスリーブの圧縮力吸収作用により、床パネル等の端部付近でねじに作用する剪断力が緩和されて、ねじが剪断されるおそれがなくなると共に、各壁パネルのねじ穴付近でのクラックの発生もなくなって、各壁パネルが破損するおそれもなくなる。
【００１３】
請求項２のように、ゴムスリーブの嵌合先端部を先細りのテーパーに形成すれば、壁パネルの嵌合穴にゴムスリーブをスムーズに嵌合させることができ、嵌合作業性が良好になる。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して詳細に説明する。
なお、図４以下の従来技術と同一構成・作用の箇所は同一番号を付して詳細な説明は省略する。
図１（Ａ）に示すように、２階の鉄骨２階床梁１の上に吸振ゴム４を乗せ、この吸振ゴム４の上に２階の床パネル２Ｂを乗せて、鉄骨２階床梁１に溶接したナット１０に、床パネル２Ｂの上方からボルト１１をねじ込み固定することにより、鉄骨２階床梁１の上に吸振ゴム４を介して床パネル２Ｂを固定する。
なお、図４に示したように、コンクリート基礎台３の上に吸振ゴム４を乗せ、この吸振ゴム４の上に１階の床パネル２Ａを乗せて、同様の工法でコンクリート基礎台３の上に吸振ゴム４を介して床パネル２Ａを固定する。
【００１５】
一方、１階の外壁パネル５Ａは、下框５ｂの段部を１階の床パネル２Ａの端部に嵌め合わせると共に、図１（Ａ）に示したように、上框５ａの段部を２階の床パネル２Ｂの端部に嵌め合わせる。
なお、上框５ａの段部の底面と床パネル２Ｂの底面との間には、組み付け誤差等を考慮して、数ｍｍの隙間ｔ１が生じるようにしている。
【００１６】
上記外壁パネル５Ａの下框５ｂは、従来と同様に、１階の床パネル２Ａの端部に木ねじ６で取り付ける。
この外壁パネル５Ａの上框５ａには、木ねじ６よりも大径の嵌合穴５ｃをあける。例えば、図２に示すように、木ねじ６のねじ径ｄ１が５ｍｍ、皿径ｄ２が２０ｍｍとした場合、嵌合穴５ｃの内径ｄ３を１５ｍｍとする。
【００１７】
上記木ねじ６には、外壁パネル５Ａの上框５ａの嵌合穴５ｃの深さにほぼ等しい長さＬで、この嵌合穴５ｃに嵌合する外径ｄ４（上記例では１５ｍｍ）の硬質ゴムスリーブ７を設け、このゴムスリーブ７の中心穴７ａに木ねじ６を挿入して、木ねじ６にゴムスリーブ７を嵌着する。
このゴムスリーブ７は、上記例では肉厚ｔ２が５ｍｍであって、この肉厚ｔ２の弾力により、吸振及び圧縮力吸収作用を有するようになる。
上記ゴムスリーブ７は、上記吸振ゴム４が２００Ｋｇ／平方ｃｍの荷重で約２ｍｍのたわみ量とした場合、これよりもたわみ量がやや多い性能のゴム素材を使用する。
上記ゴムスリーブ７の嵌合先端部７ｂは、先細りのテーパーに形成する。
【００１８】
そして、外壁パネル５Ａの上框５ａの嵌合穴５ｃに、ゴムスリーブ７を嵌着した木ねじ６を差し込み、木ねじ６を床パネル２Ｂの端部にねじ込みながら、ゴムスリーブ７を嵌合穴５ｃに嵌合させることにより、外壁パネル５Ａの上框５ａを２階の床パネル２Ｂの端部に木ねじ６で取り付ける。
なお、木ねじ６とゴムスリーブ７とを分離して、外壁パネル５Ａの上框５ａの嵌合穴５ｃに、外壁パネル５Ａの製造工場でゴムスリーブ７を予め嵌合させておいたり、施工現場でゴムスリーブ７を嵌合させたりしても良い。
上記ゴムスリーブ７の嵌合先端部７ｂは先細りのテーパーであるから、嵌合穴５ｃにゴムスリーブ７をスムーズに嵌合させることができる。
上記２階の外壁パネル５Ｂの上框５ａを鉄骨天井梁の上の横木の端部に木ねじ６で取り付ける部分もゴムスリーブ７を用いる構造とする。
【００１９】
上記構成において、図１（Ｂ）に示すように、２階の床パネル２Ｂに人や荷物の荷重Ｐが作用して、吸振ゴム４がたわんだとき、２階の床パネル２Ｂの上下振動に伴って、床パネル２Ｂに固定された木ねじ６を介して１階の外壁パネル５Ａも上下振動しようとするが、この木ねじ６にはゴムスリーブ７が嵌着されているから、木ねじ６の上下振動に伴ってゴムスリーブ７のみがたわみ、１階の外壁パネル５Ａが上下振動しなくなる。
つまり、２階の床パネル２Ｂの上下振動がゴムスリーブ７で吸振されて、１階の外壁パネル５Ａに伝達されにくくなる。
なお、上述したように、外壁パネル５Ａの上框５ａの段部の底面と床パネル２Ｂの底面との間には数ｍｍの隙間ｔ１が有るので、床パネル２Ｂの底面が外壁パネル５Ａの上框５ａの段部の底面に当接するおそれはない。
【００２０】
同様に、１階の床パネル２Ａが上下振動したとき、これに伴って１階の外壁パネル５Ａも上下振動するが、１階の外壁パネル５Ａの上下振動がゴムスリーブ７で吸振されて、２階の床パネル２Ｂに伝達されにくくなる。
これらにより、１階の外壁パネル５Ａを介して１階と２階の床パネル２Ａ，２Ｂへの振動の伝達が抑制されるのである。
【００２１】
また、２階の床パネル２Ｂの上下振動がゴムスリーブ７で吸振されて、１階の外壁パネル５Ａに伝達されにくくなることから、２階の床パネル２Ｂの上下振動に伴う圧縮力が１階の外壁パネル５Ａに作用しないので、１階の外壁パネル５Ａが弓なり状に変形しなくなる。
上記ゴムスリーブ７の圧縮力吸収作用により、各床パネル２Ａ，２Ｂ及び横木の端部付近で木ねじ６に作用する剪断力が緩和されて、木ねじ６が剪断されるおそれがなくなる。また、上下振動で伴って木ねじ６が緩んだり、外壁パネル５Ａ，５Ｂのねじ穴付近でのクラックの発生もなくなって、外壁パネル５Ａ，５Ｂが破損するおそれもなくなる。
【００２２】
上記実施の形態では、木ねじ６にゴムスリーブ７を嵌着したものであったが、図３に示すように、ボルト８ａとナット８ｂを使用して床パネル２Ｂに外壁パネル５Ａを取り付けるときは、ボルト８ａにゴムスリーブ７を嵌着すれば良い。
また、上記実施の形態では、各外壁パネル５Ａ，５Ｂの上框５ａにゴムスリーブ７を設けたものであったが、下框５ｂにゴムスリーブ７を設けるようにしても良く、上框５ａと下框５ｂの両方にゴムスリーブ７を設けるようにしても良い。
【００２３】
上記実施の形態では、１階と２階の床パネル２Ａ，２Ｂの間の外壁パネル５Ａを対象としたが、２階と３階のように、上階と下階の床パネルの間の外壁パネルにも適用できることは言うまでもない。
なお、外壁パネルのみでなく、内壁パネル等にも採用することができる。
【００２４】
【発明の効果】
以上の説明からも明らかなように、本発明の壁パネルの取り付け構造は、壁パネルの上框と下框をねじで上下階の床パネル又は横木の端部に取り付けるときに、上框と下框の少なくとも一方にあけた嵌合穴に、ねじに嵌着した硬質のゴムスリーブを嵌合させるようにしたから、ゴムスリーブの吸振作用により、壁パネルを介して上下階の床パネルへの振動の伝達が抑制されるようになる。
【００２５】
また、ゴムスリーブの圧縮力吸収作用により、圧縮力が壁パネルに作用しないので壁パネルが変形しなくなる。
さらに、ゴムスリーブの圧縮力吸収作用により、床パネル等の端部付近でねじに作用する剪断力が緩和されて、ねじが剪断されるおそれがなくなると共に、各壁パネルのねじ穴付近でのクラックの発生もなくなって、壁パネルが破損するおそれもなくなる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wall panel mounting structure capable of suppressing transmission of vibration to floor panels on upper and lower floors and preventing deformation of the wall panel.
[0002]
[Prior art]
Conventionally, as a method of building a house (including a house with a store, etc.), there are wooden, reinforced concrete and steel frame constructions. It has the advantage of being able to build a tough and economical house because it is a structure that assembles a framework, and has been receiving the most attention in recent years.
[0003]
4A and 4B, the floor panel 2B is directly fixed on the second floor or more steel frame floor beam 1 with the bolts 11 or on the concrete foundation 3 as shown in FIGS. When the floor panel 2A is directly fixed, walking vibrations and the like are directly transmitted from the floor panel 2B to the steel frame floor beam 1, and the vibration of the steel frame floor beam 1 continues, so that the walking sound is heard from the ceiling downstairs. Etc. had a problem that it greatly resonated. Further, since the second-story steel frame floor beam 1 and the concrete foundation 3 are hard, there is a problem that a burden is imposed on the feet and waist during walking.
[0004]
For this reason, the present applicant has disclosed in Japanese Patent Application No. 8-99154 a residential floor in which floor panels 2A and 2B are fixed on a steel beam 1 or a concrete foundation 3 of a house or the like via a hard vibration absorbing rubber 4. A fixing structure of the panel was proposed.
According to this, walking vibrations and the like of the floor panel 2B on the second floor are greatly absorbed by the vibration absorbing rubber 4 before being transmitted to the floor beam 1 on the second floor of the steel frame. As a result, the walking sound and the like are hardly resonated from the ceiling downstairs, that is, the walking sound and the like are absorbed by the vibration absorbing rubber 4 and the floor panel is placed on the concrete foundation 3 on the first floor via the vibration absorbing rubber 4. Even if the 2A is fixed, the function and effect of reducing walking noise and the like due to the vibration absorbing and sound absorbing functions of the vibration absorbing rubber 4 can be achieved.
[0005]
On the other hand, the outer wall panel 5A on the first floor fits the step of the lower frame 5b to the end of the floor panel 2A on the first floor and the step of the upper frame 5a to the end of the floor panel 2B on the second floor. The frames 5a and 5b are attached to the ends of the floor panels 2A and 2B with wood screws 6. Similarly, the outer wall panel 5B on the second floor also fits the step of the lower frame 5b with the step of the floor panel 2B on the second floor, and connects the step of the upper frame 5a to a crosspiece on a steel frame ceiling beam on the second floor. Each of the frames 5a and 5b is attached to the floor panel 2B and the crosspiece with a wood screw 6 by fitting to the end of the frame (not shown).
[0006]
[Problems to be solved by the invention]
By the way, as shown in FIG. 5 (A), at the portion where the outer wall panel 5A on the first floor is attached to the floor panel 2B on the second floor, as shown in FIG. (For example, if the thickness of the vibration-absorbing rubber 4 is 25 mm, the amount of deflection is about 2 mm at a load of 200 kg / square cm) when the load P acts on the floor panel 2B on the second floor. With the vertical vibration, the outer wall panel 5A on the first floor attached with the wood screws 6 also tries to vibrate vertically.
At this time, since the lower frame 5b of the first floor outer wall panel 5A is attached to the first floor floor panel 2A with the wood screws 6, the outer wall panel 5A itself cannot vibrate up and down. The outer wall panel 5A is deformed in a bow shape by the compressive force acting between the floor panel 2A on the first floor and the floor panel 2A (see a two-dot chain line).
[0007]
In addition, since the lower frame 5b and the upper frame 5a of the first-floor outer wall panel 5A are attached to the first and second floor floor panels 2A and 2B with the wood screws 6, walking vibration of the floor panels 2A and 2B of each floor is reduced. It is easily transmitted to the floor panels 2A and 2B of each floor via the outer wall panel 5A of the first floor.
Further, with the vertical vibration of each floor panel 2A, 2B, a shearing force acts on the wood screw 6 in the vicinity of each floor panel 2A, 2B and the end of the crosspiece, and the wood screw 6 may be sheared. Cracks may occur near the screw holes of the panels 5A and 5B, and the outer wall panels 5A and 5B may be damaged.
[0008]
The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a wall panel mounting structure that can suppress transmission of vibration to floor panels on upper and lower floors and can prevent deformation of the wall panel. It is assumed that.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is to fix a floor panel via hard vibration absorbing rubber on a steel floor beam or a concrete foundation of a house or the like, and to fix an end of the floor panel or a steel ceiling beam. A structure in which the steps of the upper frame and the lower frame of the wall panel are fitted to the end of the upper rung, and the fitted frame is attached to the end of the floor panel or the rung with screws.
At least one of the upper frame and the lower frame of the wall panel is provided with a fitting hole having a diameter larger than that of the screw, and the screw is fitted with a hard rubber for absorbing vibration and compressive force. An object of the present invention is to provide a mounting structure of a wall panel, wherein a sleeve is fitted.
[0010]
According to the present invention, when each step of the upper frame and the lower frame of the wall panel is fitted to the end of the floor panel or the like, and the fitted frame is attached to the end of the floor panel or the like with a screw, the upper frame is used. And a hard rubber sleeve fitted to a screw is fitted in a fitting hole formed in at least one of the lower frame. For example, a fitting hole is made in the upper frame of the wall panel on the first floor attached to the end of the floor panel on the second floor, and a rubber sleeve fitted to a screw is fitted in this fitting hole. In addition, a fitting hole may be formed in both the upper frame and the lower frame of the wall panel, and the rubber sleeve fitted to the screw may be fitted.
[0011]
Thus, when the floor panel on the second floor vibrates up and down, the wall panel on the first floor also tries to vibrate up and down via the screw fixed to the floor panel on the second floor. Since the rubber sleeve is fitted, the vertical vibration of the floor panel on the second floor is absorbed by the rubber sleeve, and is hardly transmitted to the wall panel on the first floor.
Similarly, when the floor panel on the first floor vibrates up and down, the wall panel on the first floor also vibrates up and down with this, but the vertical vibration of the wall panel on the first floor is absorbed by the rubber sleeve and the floor panel on the second floor Is difficult to be transmitted.
Thus, transmission of vibration to floor panels on the upper and lower floors via the wall panel is suppressed.
[0012]
In addition, since the vertical vibration of the floor panel on the second floor is absorbed by the rubber sleeve and is difficult to be transmitted to the wall panel on the first floor, the compressive force caused by the vertical vibration of the floor panel on the second floor acts on the wall panel on the first floor. The wall panels on the first floor are not deformed.
Further, the compressive force absorbing action of the rubber sleeve reduces the shearing force acting on the screw near the end of the floor panel or the like, eliminating the possibility of the screw being sheared and cracking the screw hole of each wall panel near the screw hole. This eliminates the risk of damage to each wall panel.
[0013]
If the fitting end of the rubber sleeve is formed to have a tapered shape, the rubber sleeve can be smoothly fitted into the fitting hole of the wall panel, and the fitting workability is improved. .
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The same components and operations as those in the prior art shown in FIG. 4 and subsequent figures are given the same reference numerals, and detailed description is omitted.
As shown in FIG. 1 (A), a rubber damper 4 is placed on a steel frame 2nd floor beam 1 on the second floor, and a second floor panel 2B is placed on this rubber damper 4 to form a steel frame 2nd floor beam. The floor panel 2B is fixed to the nut 10 welded to the floor panel 2B via the vibration absorbing rubber 4 by screwing and fixing a bolt 11 from above the floor panel 2B.
As shown in FIG. 4, the vibration absorbing rubber 4 is placed on the concrete foundation 3, and the floor panel 2A of the first floor is placed on the vibration absorbing rubber 4, and the concrete floor 3 is placed on the concrete foundation 3 in the same manner. Is fixed to the floor panel 2A via the vibration absorbing rubber 4.
[0015]
On the other hand, the outer wall panel 5A on the first floor fits the step of the lower frame 5b with the end of the floor panel 2A on the first floor, and as shown in FIG. Fit into the end of the floor panel 2B on the floor.
Note that a gap t1 of several mm is formed between the bottom surface of the step portion of the upper frame 5a and the bottom surface of the floor panel 2B in consideration of an assembly error and the like.
[0016]
The lower frame 5b of the outer wall panel 5A is attached to the end of the floor panel 2A on the first floor with a wood screw 6, as in the related art.
A fitting hole 5c having a larger diameter than the wood screw 6 is formed in the upper frame 5a of the outer wall panel 5A. For example, as shown in FIG. 2, when the screw diameter d1 of the wood screw 6 is 5 mm and the countersunk diameter d2 is 20 mm, the inner diameter d3 of the fitting hole 5c is 15 mm.
[0017]
The wood screw 6 has a length L substantially equal to the depth of the fitting hole 5c of the upper frame 5a of the outer wall panel 5A and a hard rubber having an outer diameter d4 (15 mm in the above example) fitted into the fitting hole 5c. A sleeve 7 is provided, a wood screw 6 is inserted into a center hole 7 a of the rubber sleeve 7, and the rubber sleeve 7 is fitted to the wood screw 6.
In the above example, the thickness t2 of the rubber sleeve 7 is 5 mm, and the elasticity of the thickness t2 has a function of absorbing vibration and absorbing a compressive force.
When the vibration-absorbing rubber 4 has a bending amount of about 2 mm with a load of 200 kg / square cm, the rubber sleeve 7 uses a rubber material having a slightly larger bending amount.
The fitting tip 7b of the rubber sleeve 7 is formed in a tapered shape.
[0018]
Then, a wood screw 6 fitted with a rubber sleeve 7 is inserted into the fitting hole 5c of the upper frame 5a of the outer wall panel 5A, and the rubber sleeve 7 is inserted into the fitting hole 5c while the wood screw 6 is screwed into the end of the floor panel 2B. By fitting, the upper frame 5a of the outer wall panel 5A is attached to the end of the floor panel 2B on the second floor with wood screws 6.
In addition, the wood screw 6 and the rubber sleeve 7 are separated, and the rubber sleeve 7 is previously fitted in the fitting hole 5c of the upper frame 5a of the outer wall panel 5A at the manufacturing factory of the outer wall panel 5A, or at the construction site. The rubber sleeve 7 may be fitted.
Since the fitting front end 7b of the rubber sleeve 7 is tapered, the rubber sleeve 7 can be smoothly fitted into the fitting hole 5c.
The portion where the upper frame 5a of the outer wall panel 5B on the second floor is attached to the end of the crossbar above the steel ceiling beam with a wood screw 6 also has a structure in which the rubber sleeve 7 is used.
[0019]
In the above configuration, as shown in FIG. 1B, when a load P of a person or luggage acts on the floor panel 2B on the second floor and the vibration-absorbing rubber 4 is bent, the floor panel 2B on the second floor is subjected to vertical vibration. Accordingly, the outer wall panel 5A on the first floor also attempts to vibrate up and down via the wood screws 6 fixed to the floor panel 2B, but since the rubber sleeve 7 is fitted to the wood screws 6, the vertical vibration of the wood screws 6 is caused. Accordingly, only the rubber sleeve 7 bends, and the outer wall panel 5A on the first floor does not vibrate up and down.
That is, the vertical vibration of the floor panel 2B on the second floor is absorbed by the rubber sleeve 7, and is hardly transmitted to the outer wall panel 5A on the first floor.
As described above, since there is a gap t1 of several mm between the bottom surface of the step of the upper frame 5a of the outer wall panel 5A and the bottom surface of the floor panel 2B, the bottom surface of the floor panel 2B is located above the outer wall panel 5A. There is no risk of contacting the bottom of the step of the frame 5a.
[0020]
Similarly, when the floor panel 2A on the first floor vibrates up and down, the outer wall panel 5A on the first floor also vibrates up and down with this, but the vertical vibration of the outer wall panel 5A on the first floor is absorbed by the rubber sleeve 7 and It is difficult to be transmitted to the floor panel 2B on the floor.
Thus, transmission of vibration to the floor panels 2A and 2B on the first and second floors via the outer wall panel 5A on the first floor is suppressed.
[0021]
In addition, since the vertical vibration of the floor panel 2B on the second floor is absorbed by the rubber sleeve 7 and becomes difficult to be transmitted to the outer wall panel 5A on the first floor, the compressive force accompanying the vertical vibration of the floor panel 2B on the second floor is reduced to the first floor. Does not act on the outer wall panel 5A, so that the outer wall panel 5A on the first floor does not deform into a bow shape.
Due to the compressive force absorbing action of the rubber sleeve 7, the shearing force acting on the wood screw 6 near the end of each of the floor panels 2A, 2B and the crosspiece is alleviated, and the wood screw 6 is not likely to be sheared. Further, the wood screws 6 are not loosened due to the vertical vibration, and no crack is generated near the screw holes of the outer wall panels 5A, 5B, and the outer wall panels 5A, 5B are not likely to be damaged.
[0022]
In the above embodiment, the rubber sleeve 7 is fitted to the wood screw 6, but as shown in FIG. 3, when the outer wall panel 5A is attached to the floor panel 2B using the bolt 8a and the nut 8b, The rubber sleeve 7 may be fitted to the bolt 8a.
In the above embodiment, the rubber sleeve 7 is provided on the upper frame 5a of each of the outer wall panels 5A and 5B. However, the rubber sleeve 7 may be provided on the lower frame 5b. Rubber sleeves 7 may be provided on both lower frames 5b.
[0023]
In the above embodiment, the outer wall panel 5A between the floor panels 2A and 2B on the first floor and the second floor is targeted, but the outer wall between the floor panels on the upper floor and the lower floor like the second floor and the third floor. Needless to say, it can be applied to panels.
In addition, it can be adopted not only for the outer wall panel but also for the inner wall panel and the like.

【The invention's effect】
As is clear from the above description, the mounting structure of the wall panel of the present invention is such that when the upper frame and the lower frame of the wall panel are mounted on the floor panels on the upper and lower floors or the ends of the rungs with screws, the upper frame and the lower frame are attached. Since the hard rubber sleeve fitted to the screw is fitted into the fitting hole formed in at least one of the frames, the vibration of the rubber sleeve causes the vibration to the floor panels on the upper and lower floors via the wall panel. Is suppressed.
[0025]
Further, the compressive force does not act on the wall panel due to the compressive force absorbing action of the rubber sleeve, so that the wall panel is not deformed.
Further, the compressive force absorbing action of the rubber sleeve reduces the shearing force acting on the screw near the end of the floor panel or the like, eliminating the possibility of the screw being sheared and cracking the screw hole of each wall panel near the screw hole. Is not generated, and there is no possibility that the wall panel is damaged.
