Description
本発明は、地震時における天井の振動や変位を吸収して天井の崩壊落下を防止し、安全性を向上することのできる吸振つり天井に関する。 The present invention relates to a vibration-absorbing suspended ceiling capable of absorbing the vibration and displacement of the ceiling during an earthquake to prevent the ceiling from collapsing and dropping and improving safety.
現在、建築物の天井仕上げ工事においては、住宅または特殊木造建築物等以外のほとんどの天井が「つり天井」仕上げ工事を主流としている。またその構成は、軽量スチール下地骨組不燃ボード天井の組み合わせが、コスト面における長期に渡る改善改良の結果最も低価格であると考えられ、主流となっている。かかる構成の天井はショッピングセンター・映画館・コンサートホール・体育館・公民館・消防署・警察署・工場・倉庫等と民間、公共に多く施工されている。 Currently, in ceiling finishing work for buildings, most of the ceilings other than houses or special wooden buildings are mainly "suspended ceiling" finishing work. In addition, the construction of the lightweight steel base frame incombustible board ceiling is considered to be the lowest price as a result of long-term improvement and improvement in cost. Many ceilings with this structure are installed in the private and public areas such as shopping centers, movie theaters, concert halls, gymnasiums, public halls, fire stations, police stations, factories, and warehouses.
従来、「つり天井」は、天井部分の下地骨組の下端に石こうボードをビスで固定し、金属の棒でつり下げる建築手法で、ショッピングセンター・体育館等の大勢の人々が使用する建築物に施工されているが、構造としては非構造部材としての見解で、設計の段階で耐震性についての検討はほとんどされておらず、大地震の際は崩壊して人的被害をもたらす危険性があると指摘されていた。 Traditionally, the “suspended ceiling” is an architectural method in which a gypsum board is fixed to the lower end of the base frame of the ceiling with a screw and suspended with a metal rod. It is applied to buildings used by many people such as shopping centers and gymnasiums. However, as a structure, it is a view as a non-structural member, and there has been little consideration on seismic resistance at the design stage, and there is a danger that it will collapse and cause human damage in the event of a large earthquake It was pointed out.
現実に、近年日本で2005年8月16日発生した宮城沖地震により、３１人が重軽傷を負った仙台市の屋内プールの天井が落下した事故以降、天井の耐震性に、大きな関心が寄せられ、また、2007年3月25日に発生した能登半島地震においても、避難所になるはずの体育館等で天井落下の被害が報告された。 In fact, in recent years, the Miyagi-oki earthquake that occurred in Japan on August 16, 2005 has attracted a great deal of attention to the earthquake resistance of the ceiling after the fall of the indoor pool ceiling in Sendai, where 31 people were seriously injured. In addition, after the Noto Peninsula earthquake that occurred on March 25, 2007, damage to ceilings was reported at gymnasiums and other facilities that should be shelters.
そうした時期に発生した、東日本大震災では、地震とそれによる津波によって多大な被害を受け、天井落下による事故報告が数多く発表され、改めて天井の落下防止対策が必要不可欠となり、早急に対策案を発案し、解決しなければならない。 In the Great East Japan Earthquake that occurred during such a period, the earthquake and the tsunami caused it caused great damage. Many reports of accidents due to falling ceilings were announced, and measures to prevent falling ceilings were indispensable. , Have to solve.
天井の崩壊防止策の対応施工要領には、国土交通省が2001年に技術指針で作成した、第一に壁とつり天井の間に隙間を設け、横揺れでの損傷を防ぐ、第二につり天井の揺れを抑えるために下地骨組みを補強材でつなぐ、ことなどを求めているが、法的強制力はなく、都道府県を通して周知を図っている段階である。 The construction guidelines for measures to prevent the collapse of the ceiling were created in 2001 by the Ministry of Land, Infrastructure, Transport and Tourism in accordance with the technical guidelines. First, a gap was created between the wall and the suspension ceiling to prevent damage from rolling. In order to suppress the shaking of the suspended ceiling, it is required to connect the base frame with a reinforcing material, but it is not legally enforceable and is in the stage of publicizing through the prefectures.
しかし、前記の崩壊防止の施工方法では、工事が大規模になり、経済的に負担が大きくなるため、各自治体の施設の対応が遅れているのが現状である。 However, in the construction method for preventing collapse described above, since the construction is large-scale and the burden is increased economically, the response of the facilities of each local government is delayed.
民間施設においても、崩壊防止策の対応施工は深刻であり、サービス系建築物の天井は、デザイン考慮のシステム天井が多く容易に対応策は見つけきれずにいるのが現状である。 Even in private facilities, the countermeasures for the collapse prevention measures are serious, and the ceilings of service buildings are currently in a situation where there are many system ceilings in consideration of the design, and the countermeasures cannot be easily found.
よって、崩壊防止策において最も必要な課題は、在来の「つり天井」に変わる新しい天井の構成を提案することであり、さらにかかる構成は施工の迅速且つ簡易性及び経済的に負担のかからない価格設定であることが望ましい。 Therefore, the most necessary issue in the collapse prevention measures is to propose a new ceiling configuration that replaces the conventional “suspended ceiling”, and this configuration is quick and simple in construction, and does not cost economically. It is desirable to set.
また、天井構成の構築にあたっては、照明や空調などの設備機器や天井裏のダクト配管配線などが天井の構造に悪影響を与えているため、前記の種々設備機器やダクト配管配線のためのつり金具を独立させた事前の天井伏せ図設計が必要である。 In addition, when constructing the ceiling configuration, equipment such as lighting and air conditioning and duct piping wiring on the back of the ceiling have an adverse effect on the ceiling structure. It is necessary to design the floor plan in advance.
本発明が解決しようとする課題は、地震時に天井の崩壊落下を防止し、人的被害を起こさないつり天井を実現することである。 The problem to be solved by the present invention is to realize a suspended ceiling that prevents collapse of the ceiling during an earthquake and does not cause human damage.
そのためには、従来の「つり天井」の概念を捨て、今までとは異なるつり天井の開発が求められる。 For that purpose, the concept of the conventional “suspended ceiling” is abandoned, and the development of a different suspended ceiling is required.

つまり、天井伏せ計画図例２図２１には、図２３の中央部の固定範囲天井部分１４と外周部の図２２の吸振範囲天井部分１５とで形成され、中央部の吊り天井部分を外周部の粘弾性の天井板２２で地震時の振動や変位を吸収する。 That is, the ceiling-down plan example 2 in FIG. 21 is formed by the fixed range ceiling part 14 in the center of FIG. 23 and the vibration absorption range ceiling part 15 in FIG. The viscoelastic ceiling plate 22 absorbs vibration and displacement during an earthquake.
天井板２２は、（図１７、図１８、図１９、図２０参照）天井板材とその四方に取り付けられる天井板レール枠２０と天井板ジョイント枠２１とで構成される。 The ceiling plate 22 (see FIGS. 17, 18, 19, and 20) includes a ceiling plate material, a ceiling plate rail frame 20 attached to the four sides thereof, and a ceiling plate joint frame 21.
天井板２２の天井板材と天井板枠は、少なくとも柔軟性を有する、主に粘弾性材質の部材を使用するため、変位に対応し亀裂破壊がなく、軽量である。 Since the ceiling plate material and the ceiling plate frame of the ceiling plate 22 are mainly viscoelastic materials having at least flexibility, they are light and free from crack destruction corresponding to displacement.
吊りボルト３と野縁レール下部部材１７と通し野縁１８は、天井板の中心部の所定の箇所（図１６、図１７、図１８、図２５、図２６参照）で吊りボルト用ナット８で上下に挟み強固に取り付ける。 The suspension bolt 3, the field edge rail lower member 17, and the through field edge 18 are attached to the suspension bolt nut 8 at a predetermined position (see FIGS. 16, 17, 18, 25, and 26) in the center of the ceiling plate. Install it firmly between the top and bottom.
また吊りボルトと野縁レール上部部材１６と野縁レール下部部材１７と通し野縁１８は、天井板のジョイント部の所定の箇所（図１６、図１９、図２０、図２５、図２６参照）で接合用ネジ２４と接合用ナット２５で上下に挟み強固に取り付ける。 Further, the suspension bolt, the field edge rail upper member 16, the field edge rail lower member 17, and the through field edge 18 are predetermined portions of the joint portion of the ceiling plate (see FIGS. 16, 19, 20, 25, and 26). Then, it is sandwiched up and down with the joining screw 24 and the joining nut 25 and attached firmly.
固定範囲天井部分の天井板２２の取り付け施工要領は両方の天井板レール枠２０を同時に野縁二連レールの所定の箇所（図２４、図２５、図２６参照）から差し込み取り付ける。 The installation procedure of the ceiling plate 22 in the fixed range ceiling portion is to insert and attach both the ceiling plate rail frames 20 simultaneously from predetermined positions (see FIGS. 24, 25, and 26) of the double edge rails.
吸振範囲天井部分の天井板２２の取り付け施工要領は片方の天井板レール枠８を野縁一連レールの所定の箇所（図２５、図２６参照）から差し込み、片方の天井板２２を天井板受けアングル１９の上部に乗せ掛ける。 The installation procedure of the ceiling plate 22 in the ceiling of the vibration absorption range is as follows. One ceiling plate rail frame 8 is inserted from a predetermined position (see FIGS. 25 and 26) of the continuous edge rail, and one ceiling plate 22 is attached to the ceiling plate receiving angle. Place on top of 19.
吸振範囲天井部分の片方の天井板２２を天井板受けアングル１９の上部（図２５、図２６参照）に乗せ掛けた部分おいて、屋内外周部の壁面２と天井板２２との間に所定の隙間を設け、地震時の水平方向の振動や変位を吸収する。 In a portion where one ceiling plate 22 of the vibration absorption range ceiling portion is placed on the upper portion of the ceiling plate receiving angle 19 (see FIGS. 25 and 26), a predetermined gap is provided between the wall surface 2 of the indoor outer peripheral portion and the ceiling plate 22. Create a gap to absorb horizontal vibration and displacement during an earthquake.
天井板２２の天井板材や天井板枠の色彩柄形状材質等は、用途に合わせて決めることができ天井板材と四方の天井板枠との組み合わせで多彩なデザインを可能にする。 The ceiling board material of the ceiling board 22 and the color pattern shape material of the ceiling board frame can be determined according to the application, and various designs are possible by combining the ceiling board material and the four-way ceiling board frame.
天井伏せ計画図例２図２１による規格形状に成型された天井板２２に、照明器具の取り付け方法において（図２７、図２８参照）、照明器具取付用部材２６を直接吊りボルト３に強固に接合し、照明器具１３を取付用部材に直接吊るすことにより、天井の荷重負担を抑制することができる。 Ceiling-down plan diagram 2 In the lighting fixture mounting method (see FIGS. 27 and 28), the lighting fixture mounting member 26 is directly bonded to the suspension bolt 3 directly to the ceiling plate 22 molded into the standard shape shown in FIG. And the load burden of a ceiling can be suppressed by hanging the lighting fixture 13 directly on the member for attachment.
また、つり天井に連続通しによって照明器具を取り付ける方法において（図２９、図３０参照）、照明器具１３を照明器具用野縁２７に直接取り付けることにより、天井の荷重負担を抑制することができる。 Moreover, in the method of attaching a lighting fixture to the suspension ceiling by continuous threading (see FIGS. 29 and 30), the load burden on the ceiling can be suppressed by attaching the lighting fixture 13 directly to the field edge 27 for the lighting fixture.
天井勾配においても、（図３１、図３２参照）勾配用部材２８を野縁レールの上下にはめ込み勾配角度を自在に調整できる。 Even in the case of a ceiling gradient (see FIGS. 31 and 32), the gradient member 28 can be fitted to the top and bottom of the field rail to freely adjust the gradient angle.
本発明において、建築基準法試案の基準外天井および吊りボルト３の長さに応じての、異形状の野縁一連レールの組み合わせ（図３３、図３４、図３５参照）の応用も可能であり、より天井下地骨組が簡素化・軽量化ができ、施工性も格段に向上する。 In the present invention, it is also possible to apply a combination of irregularly shaped field edge series rails (see FIGS. 33, 34, and 35) according to the length of the ceiling outside the standard and the suspension bolt 3 of the draft of the Building Standard Law. The ceiling foundation frame can be simplified and lighter, and the workability is greatly improved.
在来の「つり天井」の地震時の崩壊防止策の対応施工要領は、国土交通省が2001年に技術指針で作成した、第一に壁とつり天井の間に隙間を設け、横揺れでの損傷を防ぐ、第二につり天井の揺れを抑えるために下地骨組を補強材でつなぐ、といった耐震補強重視の対策案があるが、前記の崩壊防止施工方法では工事が大規模になり、経済的に負担が大きくなるため、各自治体の施設の対応が遅れているのが現状である。 The conventional construction procedure for preventing the collapse of the “suspended ceiling” in the event of an earthquake was created by the Ministry of Land, Infrastructure, Transport and Tourism in accordance with the technical guidelines in 2001. First, a gap was created between the wall and the suspended ceiling. There are measures to emphasize seismic reinforcement, such as connecting the foundation frame with a reinforcing material to prevent damage to the ceiling, and secondly, the above-mentioned collapse prevention construction method makes the construction large-scale and economical The current situation is that the response of the facilities of each local government is delayed due to the increased burden.
本発明の吸振つり天井は、従来の「つり天井」の概念を捨て、今までとは異なるつり天井の開発により、前記の国土交通省の技術指針における耐震補強工事が省かれ、極端に工期短縮が出来、施工要領の簡易化により安全性も高くなり、コスト面でも前記の国土交通省のつり天井に関する技術指針施工よりも減額が見込まれるなど、数多くの問題解決となり、国土交通省による新しい制度の対処法として、また民間商業施設等の崩壊危険予知の対策として、多大な産業需要が期待できる。 The vibration-absorbing suspended ceiling of the present invention abandoned the concept of the conventional “suspended ceiling”, and the development of a suspended ceiling different from the previous one eliminates the seismic reinforcement work in the technical guidelines of the Ministry of Land, Infrastructure, Transport and Tourism, and extremely shortens the construction period. It is possible to solve the many problems, such as a reduction in the cost compared to the technical guidelines for the suspended ceiling of the Ministry of Land, Infrastructure, Transport and Tourism. As a countermeasure for this, and as a measure for predicting the risk of collapse of private commercial facilities, a great industrial demand can be expected.
近年日本では2005年8月16日発生した宮城沖地震以降断続して起きた地震と、2011年3月11日に発生した東日本大震災により、既設建築物の天井の危険予知崩壊防止策の済んでいない施設が数多くあり、新築建築物の計画においても耐震用天井は必然の考慮であり、今後の「つり天井」の工法として本発明の吸振つり天井は、産業上の利用可能性は多大である。
In recent years, in Japan, after the Miyagi-oki earthquake that occurred on August 16, 2005, and the Great East Japan Earthquake that occurred on March 11, 2011, the measures to prevent the danger prediction collapse of the ceiling of existing buildings have been completed. There are not many facilities, and earthquake-proof ceilings are inevitable in the planning of new buildings, and the vibration-suspended ceiling of the present invention has great industrial applicability as a method of future "suspended ceiling". .
そしてまさに現在、国土交通省が報道発表資料によりパブリックコメントの募集告知を行った天井脱落対策に係る技術基準原案の（３ー１）仕様１の基準内容に本発明の吸振つり天井が該当することに伴い、前記の国土交通省の新しい制度の対処法として充分に機能する発明であり、また天井診断調査報告による崩壊脱落危険予知の対策案としても対応が可能である。 And now, the vibration-absorbing suspended ceiling of the present invention falls within the standard contents of (3-1) Specification 1 of the draft technical standards related to measures against dropout of the ceiling, which the Ministry of Land, Infrastructure, Transport and Tourism has made public announcements of public comments through press releases. Accordingly, the present invention functions sufficiently as a countermeasure for the new system of the Ministry of Land, Infrastructure, Transport and Tourism, and can be dealt with as a countermeasure plan for the risk of collapse and fall off by a ceiling diagnosis survey report.
もちろん、天井おける建築基準範囲以外のシステム天井としても、規制緩和の部分で従来のつり天井に変わる有利点は数多く図られ、これからの日本のシステム天井産業上、利用可能性は十分に見込まれ、天井産業界において大きなイノベーションとなるものである。 Of course, the system ceiling outside the building standard range on the ceiling has many advantages that can be changed to the conventional suspension ceiling in the part of deregulation. It is a big innovation in the ceiling industry.
