Description
本発明は、シングル固定タイプの野縁固定金具および、シングル固定タイプにて施工された既設天井下地における野縁の耐震補強構造に関する。 The present invention relates to a single-fixed type field edge fixing bracket and a seismic reinforcing structure for a field edge in an existing ceiling base constructed by a single fixed type.
一般に、在来天井は、吊り部材（吊りボルト、吊りワイヤ等）を介して躯体天井部に支持される複数の野縁受け（チャンネル材）と、野縁固定金具（挟込み固定タイプ、シングル固定タイプ等）を介して野縁受けに支持される複数のチャンネル状の野縁と、野縁にビス止めされる天井パネルとから構成される。
挟込み固定タイプの野縁固定金具は、主に予め耐震性が求められる建物の天井下地に用いられ（特許文献１、図４、図６参照）、それ以外の建物の天井下地には、シングル固定タイプの野縁固定金具が用いられている（特許文献２、図１、図４（Ａ）、および特許文献３、図８参照）。
In general, a conventional ceiling has a plurality of field receivers (channel materials) supported by the ceiling of the frame via suspension members (suspending bolts, suspension wires, etc.) and field edge fixing brackets (pinned fixed type, single fixed) A plurality of channel-shaped field edges supported by a field edge receiver via a type edge) and a ceiling panel screwed to the field edge.
The pin-fixed type field edge fixing bracket is mainly used for a ceiling base of a building in which earthquake resistance is required in advance (refer to Patent Document 1, FIG. 4, and FIG. 6). A fixed-type field edge fixing bracket is used (see Patent Document 2, FIG. 1, FIG. 4A, and Patent Document 3, FIG. 8).
野縁固定金具は、野縁受けに取り付けられる逆Ｌ字状の野縁受け取付け部と、その垂下両側端部に、上方に拡開した野縁の上端部両側内方に形成された逆Ｕ字状溝内に挿入される上方に直角折曲させた野縁係止片とにより一体形成され、逆Ｕ字状溝内に挿入した野縁係止片の上端面で野縁を支持受けするように構成されている。シングル固定タイプの野縁固定金具の野縁係止片は、単体使用となるため野縁受けの下面側に配設されたものが採用され、特許文献２の図４（Ｂ）の如きに野縁受け外方に向けて配設されたものは採用されていない。
挟込み固定タイプの野縁固定金具は、指圧変形不能な板厚が約１．６ｍｍの厚板でプレス成型されたものを組として、野縁受けに挟み込ませてネジ止め固定して取り付けられており、野縁係止片も２カ所で野縁を支持受けするため、ジョイント強度や耐震強度が得られるものの、２枚を合わせ固定する作業が強いられ、取付け作業に時間を有するという問題がある。
The field edge fixing bracket includes an inverted L-shaped field edge receiver mounting portion attached to the field edge receiver, and inverted U formed on both sides of the hanging side at the upper end portion of the upper edge of the field edge expanded upward. It is integrally formed with a field edge locking piece bent at a right angle upward and inserted into the letter-shaped groove, and the field edge is supported and received by the upper end surface of the field edge locking piece inserted into the inverted U-shaped groove. It is configured as follows. The single-fixed type field-edge fixing bracket has a field-edge locking piece that is disposed on the lower surface side of the field-edge receiver because it is used as a single piece. As shown in FIG. Those arranged toward the outside of the edge receiver are not adopted.
The fixed type of edge fixing bracket is attached by fixing it with a screw that is inserted into a field edge receiver as a set of press-molded thick plates with a thickness of about 1.6 mm that cannot be deformed with acupressure. In addition, because the field edge locking piece also supports and receives the field edge at two locations, joint strength and seismic strength are obtained, but the work of fixing and fixing the two sheets is forced, and there is a problem that the installation work takes time .
しかしながら、従来のシングル固定タイプで採用されていた野縁固定金具は、挟込み固定タイプのものに比し板厚が０．６ｍｍ程度の指圧変形可能な薄板でプレス成型されており、横向きに配設された野縁受けに対して、その拡開側で野縁受け取付け部の先端側を、手で折り込ませて折曲しただけの簡単な取り付け方法が採用され、しかも、単体で野縁を支持受けしているため、取付け作業時間の短縮は図られるものの、地震の揺れによって変形し易く、野縁受けとのジョイントにガタツキを生じ、野縁の支持受け機能にも支障をきたし、ジョイント強度は勿論、耐震強度が極めて劣るという問題がある。そこで近年、その様な天井下地における野縁の耐震強度を更に向上させることが求められるが、天井下地における野縁の耐震強度を向上させる方法としては、例えば、従来の挟込み固定タイプのものを採用して強度アップをすることも考えられるが、既設の野縁固定金具を取り外す大規模な工事が必要となり、そのまま採用することはできないという問題がある。一方、野縁受けに取り付けられた既設の野縁固定金具にそのまま採用することも考えられるが、それではシングル固定タイプの取付け作業性の良さが無くなり、過剰品質となってしまうため、その作業性を維持しつつ、耐震強度を向上させることができ、かつ、耐震機能を有していない既設の野縁固定金具に対しても耐震補強機能を持たせることのできる野縁固定金具の出現が望まれていた。
本発明は、上記の如き問題点を一掃すべく創案されたものであって、シングル固定タイプの野縁固定金具でありながら、挟込み固定タイプで用いられる野縁固定金具と同様の指圧変形不能な厚板材を採用できるようにし、野縁受けへの取り付けに当たっては、仮組付けした状態から位置合わせ調整やビス止め作業による本固定が行えるようにし、取付け作業を簡略化して、新設工事や既設補強工事の如何を問わず作業性及び効率を向上させることができるばかりか、既設天井下地における耐震機能を持たない単体で取り付けられた既設固定金具に対して、その表面を覆うように野縁固定金具を密着重合させる取付けが行え、地震等の揺れを生じても、その野縁受け取付け部と野縁受け挟持片とによって、既設取付け部を外嵌狭圧し、野縁受けに対してしっかりと固定させてジョイント強度を向上させ、ガタツキ発生を防止しすることができると共に、隣接並設された野縁係止片が既設係止片の変形応力を受け止めて変形を抑止して、その野縁支持受け機能の維持を図り、既設固定金具との共同作用により、天井下地全体の耐震強度を向上させることを可能ならしめることができる野縁固定金具および既設天井下地における野縁の耐震補強構造を提供することにある。 The present invention was devised to eliminate the above-mentioned problems, and it is a single fixed type field edge fixing bracket, but it cannot be deformed with acupressure similar to the field edge fixing bracket used in the pinching fixed type. Thick plate material can be used, and when installing to the edge holder, it is possible to perform permanent adjustment by positioning adjustment and screwing work from the temporarily assembled state, simplifying the installation work, new construction work and existing installation In addition to being able to improve workability and efficiency regardless of the type of reinforcement work, it is also possible to fix the edge of the existing fixing bracket that is attached to the existing ceiling base that does not have an earthquake resistance function so as to cover the surface. The bracket can be attached and polymerized closely, and even if an earthquake or other shaking occurs, the existing edge of the mounting area is tightly fitted by the field edge mounting area and the field edge holder clamping piece, It can be firmly fixed to improve joint strength and prevent rattling, and adjacent side edge locking pieces receive deformation stress of existing locking pieces to prevent deformation. In addition, it is possible to maintain the field edge support receiving function and to improve the seismic strength of the entire ceiling basement through the joint action with the existing fixing basement, It is to provide a seismic reinforcement structure.
上記課題を解決するために本発明が採用した野縁固定金具は、吊り部材を介して躯体天井部に支持される複数の野縁受けと、上方に拡開した両側上端部の内方に逆Ｕ字状溝を有する複数のチャンネル状野縁とを、野縁受けに取り付けられる野縁受け取付け部と、その垂下部の両端側に、前記逆Ｕ字状溝内に挿入させて野縁を支持受けするよう上方に折曲された野縁係止片とを有する野縁固定金具を介して支持するに、前記野縁受け取付け部は、く字状に折曲形成され、その上部に、野縁受け幅内の中間位置から上方に立ち上がり、立上り幅を２分位置で折曲変姿可能に形成された立上り片と、該立上り片から裏面側の野縁受けに達するく字状に折曲する野縁受け挟持片を備えて構成され、前記野縁係止片を前記逆Ｕ字状溝内に挿入支持させた状態から、前記野縁受け取付け部を野縁受けに面当てし、前記立上り片を野縁受け裏面側に押圧折曲させて野縁受け挟持片を野縁受けに仮組付け可能とし、前記折曲されて対面する立上り片同士をビス固定することで、野縁受け取付け部と野縁受け挟持片とにより野縁受けに挟持すべく構成せしめたことを特徴とするものである。
また、上記課題を解決するために本発明が採用した既設天井下地における野縁の耐震補強構造は、既設の天井下地において、野縁受けに表面側から裏面側に折曲されて取り付けられた逆Ｌ字状の既設取付け部の垂下部両端側に一体形成されて、上方に拡開したチャンネル状野縁の上端部の両側内方に形成された逆Ｕ字状溝内に挿入された既設係止片によって野縁を支持受けさせた野縁の既設固定金具を、新たな野縁固定金具を用いて耐震補強するに、前記野縁固定金具を、既設取付け部に重合支持されるく字状に折曲された野縁受け取付け部と、その垂下両側端部に、前記逆Ｕ字状溝内に挿入させて既設係止片と並設して野縁を支持受けする上方に折曲せしめた野縁係止片と、前記野縁受け取付け部の上部側に、野縁受け幅内の中間位置から上方に立ち上がり、立上り幅を２分位置で折曲変姿可能に形成された立上り片と、該立上り片から裏面側の野縁受けに達するく字状に折曲された野縁受け挟持片とで一体形成せしめて構成し、前記野縁係止片を前記逆Ｕ字状溝内に挿入支持させた状態から、前記野縁受け取付け部を既設取付け部に面接し、前記立上り片を野縁受け裏面側に押圧折曲させて野縁受け挟持片を野縁受けに仮組付けし、前記折曲されて対面する立上り片同士をビス固定することで、野縁受け取付け部と野縁受け挟持片とにより既設取付け部を外嵌して野縁受けに挟圧させ、野縁係止片を、既設係止片と共同して隣接支持受けせしめることを特徴とするものである。
In order to solve the above-mentioned problems, the field edge fixing bracket adopted by the present invention is reverse to the inside of the plurality of field edge supports supported by the frame ceiling part via the suspension members and the upper end parts on both sides widened upward. A plurality of channel-shaped field edges having U-shaped grooves are inserted into the inverted U-shaped grooves at both ends of a field edge receiving mounting part that is attached to the field edge receiving part and the hanging part, and the field edges are formed. In order to support via a field edge fixing bracket having a field edge locking piece bent upward so as to be supported and received, the field edge mounting part is bent into a square shape, and at the upper part thereof, Stands upward from an intermediate position within the field edge receiving width, and rises at a rising width of 2 minutes so that it can be bent and folds in a square shape reaching the edge edge receiver on the back side from the rising piece. It is configured to have a curved edge receiving pinching piece, and the field edge locking piece is inserted and supported in the inverted U-shaped groove. From the state, the field edge receiving attachment portion is faced to the field edge receiver, the rising piece is pressed and bent to the back surface of the field edge receiver, and the field edge holder holding piece can be temporarily assembled to the field edge receiver, The rising pieces that are bent and face each other are screw-fixed to each other so that they can be clamped by the field edge receiving portion by the field edge receiving mounting portion and the field edge receiving holding piece.
In addition, the seismic reinforcement structure for the field edge in the existing ceiling foundation adopted by the present invention to solve the above problems is the reverse of the existing ceiling foundation that is bent and attached to the field edge receiver from the front side to the back side. An existing member integrally formed on both ends of the hanging portion of the L-shaped existing mounting portion and inserted into an inverted U-shaped groove formed on both sides of the upper end portion of the channel-shaped field edge expanded upward. In order to seismically reinforce the existing fixed bracket of the field edge supported and received by the stop piece using a new field edge fixed bracket, the above-mentioned field edge fixed bracket is overlapped and supported by the existing mounting part. Folded to the upper edge where the field edge is supported and received by inserting it into the inverted U-shaped groove at the both ends of the hanging edge of the field edge receiving attachment part and the existing locking piece. From the intermediate position within the field edge receiving width to the upper side of the field edge locking piece and the field edge receiving mounting part A rising piece formed so as to be able to be bent at a rising width of 2 minutes, and a field edge receiving piece bent into a square shape reaching the back edge receiving edge from the rising piece. From the state in which the field edge locking piece is inserted and supported in the inverted U-shaped groove, the field edge receiving mounting part is in contact with the existing mounting part, and the rising piece is connected to the field edge. By pressing and bending to the back side of the receiving side, the edge holder holding piece is temporarily assembled to the edge receiver, and the bent pieces facing each other are screwed together to fix the edge receiving part and the edge receiver. The existing mounting portion is externally fitted with the clamping piece and is clamped to the field edge receiver, and the field edge locking piece is received adjacent to and supported by the existing locking piece.
本発明は、上記のように構成したことにより、シングル固定タイプの野縁固定金具でありながら、挟込み固定タイプのものと同様の指圧変形不能な厚板材を採用することができ、野縁受けへの取り付けに当たっては、天井下地の新規施工は勿論、既設天井下地の補強工事であっても、野縁の既設固定金具にセットして、折曲変姿可能に形成された立上り片を手で押圧するだけの簡単な操作で仮組付け固定が行え、この仮組付けした状態から、位置合わせ調整や対面する立上り片同士をビス止めする本固定作業が容易に行えるようになり、取付け作業を簡略化して、補強工事の作業性及び効率を向上させることができるばかりか、耐震機能を持たない単体で取り付けられた野縁の既設固定金具に対して、その表面を覆うように密着重合した取付けができるので、地震等の揺れを生じても、野縁受け取付け部と野縁受け挟持片とによって、既設取付け部を確実に外嵌狭圧して変形させた状態で、野縁受けに対してしっかりと固定させた補強を行うことができ、ジョイント強度が向上されて、ガタツキ発生を防止しすることができると共に、隣接並設させた垂下部を含む野縁係止片が既設係止片の上下や横方向への変形応力を受け止めてその変形を抑止し、野縁を逆Ｕ字状溝内で共同して支持受けできるようになり、その支持受け強度を向上させることができる。その結果、耐震補強用として用いられる野縁固定金具の補強機能により、既設固定金具自体の支持受け機能の維持が図られ、両者の共同作用により、天井下地全体の耐震強度を向上させることができる。

野縁係止片６２は、既設係止片５２の略３倍の支持受け幅を有し、それぞれ外方に傾斜せしめて逆ハ字状に形成されており、逆Ｕ字状溝７１内に挿入して野縁７を支持受けした際に、その上端となる板厚内側角部を線当接させて、野縁７の自重や天井パネル８の自重で長手方向への滑り止めが成されるべく構成されている。
また、野縁係止片６２が設けられた垂下部６１ａの両端側をハ字状に傾斜する傾斜辺６１ｃに形成し、逆Ｕ字状溝７１を形成する野縁７の両折曲片７１ａの先端を、傾斜辺６１ｃに沿って自重案内させて当接支持可能に構成される。この傾斜辺６１ｃは、直線状や湾曲状（ノ字状）に形成されるが、図３（Ｃ）に示すように、垂下部６１ａの下端を折曲させて野縁係止片６２が形成された側（正面側）が背面側よりも小さい円弧をもって刃状に形成されており、折曲片７１ａの先端を天井パネル８を含む自重により、しっかりと噛み込み係合して挟持されるようになっている。
つまり、野縁７の幅寸法や折曲片７１ａの折曲寸法は、厳密に規定されるものではなく、所定の範囲で融通し得るため、野縁７の両折曲片７１ａは、その先端を、傾斜辺６１ｃと外方に傾斜する野縁係止片６２とにより形成される略Ｖ字状の折曲片挿入溝６５で支持することにより、野縁７の幅方向へのガタツキを規制して、建付け誤差および振動を吸収することができる。
The field edge locking piece 62 has a support receiving width approximately three times that of the existing locking piece 52 and is formed in an inverted C shape by inclining outward, and in the inverted U-shaped groove 71. When the field edge 7 is inserted and supported, the inner corner of the plate thickness which is the upper end of the field edge 7 is brought into line contact with the weight of the field edge 7 and the weight of the ceiling panel 8 to prevent slipping in the longitudinal direction. It is configured to
Further, both end sides of the hanging part 61 a provided with the field edge locking piece 62 are formed in the inclined side 61 c inclined in a C shape, and the both folded pieces 71 a of the field edge 7 forming the inverted U-shaped groove 71. The tip of each of these is guided by its own weight along the inclined side 61c so as to be able to contact and support. The inclined side 61c is formed in a straight line shape or a curved shape (in a square shape), but as shown in FIG. 3C, the lower edge of the hanging portion 61a is bent to form a field edge locking piece 62. The formed side (front side) is formed in a blade shape with a smaller arc than the back side, and the tip of the bent piece 71a is firmly bitten and engaged by its own weight including the ceiling panel 8 so as to be sandwiched. It has become.
That is, the width dimension of the field edge 7 and the bending dimension of the bent piece 71a are not strictly defined, and can be accommodated within a predetermined range. Is supported by a substantially V-shaped bent piece insertion groove 65 formed by the inclined side 61c and the field edge locking piece 62 that is inclined outward, thereby regulating the backlash of the field edge 7 in the width direction. Thus, installation errors and vibrations can be absorbed.
このように構成された野縁固定金具６を、新設天井下地の施工に使用する場合には、図７に示すように、従来のシングル固定タイプのものと同様に、野縁係止片６２を野縁受け４の下面域側に配設し、特に、その支持受け幅を略同幅寸法をもって形成させて、野縁受け取付け部６１や野縁受け挟持片６４を野縁受け４の縦・横幅に適合してく字状（逆Ｌ字状）に折曲して形成されている。この様に形成すると、野縁受け４の略下面全域幅内で野縁受け４の下面域と野縁係止片６２との間で、逆Ｕ字状溝７１の上辺を挟み込んで野縁７を支持受けできるので、地震等の揺れを生じても、両者間における共同挟持作用により、上下や横方向への変形応力を均等に受け止めてガタツキ規制でき、その耐震強度が向上された耐震構造を得ることができる。さらに、既設の天井下地においても、既設固定金具５（既設係止片５２）が配設されていない側の野縁受け４に対向配設させた仕様態様で取付けすることも可能となり、野縁係止片６２を、既設係止片５２に近接または当接する幅寸法に形成して並設することができ、更に、両側野縁係止片６２間の幅を、両側既設係止片５２間の内法幅寸法に設定して既設係止片５２とオーバーラップ（重合）状態で並設することが可能となる。 When the field edge fixing bracket 6 configured in this way is used for the construction of a new ceiling foundation, as shown in FIG. Arranged on the lower surface area side of the field edge receiver 4, and in particular, the support receiving width is formed with substantially the same width dimension so that the field edge receiver mounting portion 61 and the field edge receiver clamping piece 64 are vertically / It is formed by bending in a letter shape (inverted L shape) that fits the width. When formed in this manner, the upper edge of the inverted U-shaped groove 71 is sandwiched between the lower surface area of the field edge receiver 4 and the field edge locking piece 62 within the substantially entire lower surface width of the field edge receiver 4. Therefore, even if an earthquake or other shaking occurs, the joint clamping action between the two can equally accept the deformation stress in the vertical and lateral directions and regulate the rattling, and the seismic structure has improved seismic strength. Can be obtained. Further, even in the existing ceiling base, it is possible to attach the base plate in a specification mode in which it is opposed to the field edge receiver 4 on the side where the existing fixing bracket 5 (the existing locking piece 52) is not disposed. The locking pieces 62 can be formed side by side with a width dimension close to or in contact with the existing locking pieces 52, and the width between the side edge locking pieces 62 is set between the both side existing locking pieces 52. It is possible to set the inner width of the inner locking piece 52 and the existing locking piece 52 in an overlapped (overlapped) state.
また、既設の天井下地の施工に使用する場合には、既設固定金具５の既設係止片５２が野縁受け４の下面域側に配設されているので、この既設係止片５２と背反する野縁受け４の外方側に野縁係止片６２を形成する。立上り片６３は、野縁受け４横幅の既設固定金具５の板厚（肉厚）やリブ厚分を考慮して配置形成することが好ましいが、特に、野縁受け取付け部６１は、く字状に折曲形成されているので、その上方に折曲する傾斜面で、既設取付け部に面当てした際、野縁受け４の縦幅寸法、つまり、既設係止片５２の上端部から既設取付け部５１の角部までの長さの寸法誤差を吸収することができ、また、野縁受け挟持片６４も狭圧できるので、立上り片６３同士が必ずしも密着する必要はなく、形状変更が強いられるものではない。なお、この様に形成した野縁固定金具６を、既設固定金具５（既設係止片５２）が配設されていない側の野縁受け４に対向配設させて使用することもできる。
Further, when used for the construction of an existing ceiling base, the existing locking piece 52 of the existing fixing bracket 5 is disposed on the lower surface area side of the field edge receiver 4, so A field edge locking piece 62 is formed on the outer side of the opposite field edge receiver 4. The rising piece 63 is preferably arranged and formed in consideration of the plate thickness (thickness) and the rib thickness of the existing fixed metal fitting 5 having a lateral width, and in particular, the field edge mounting portion 61 has a rectangular shape. Since it is formed in a bent shape, when it is faced to the existing mounting portion with an inclined surface that bends upward, the vertical width dimension of the field receiver 4, that is, from the upper end of the existing locking piece 52 A dimensional error in the length to the corner of the mounting portion 51 can be absorbed, and the field edge holding piece 64 can also be narrowed. Therefore, the rising pieces 63 do not necessarily need to be in close contact with each other, and the shape change is strong. It is not something that can be done. The field edge fixing bracket 6 formed in this way can be used by being disposed opposite to the field edge receiver 4 on the side where the existing fixing bracket 5 (the existing locking piece 52) is not disposed.
叙述の如く構成された本発明の実施例の形態において、いま、吊り部材２を介して躯体天井部３に支持される複数の野縁受け４と、上方に拡開した両側上端部の内方に逆Ｕ字状溝７１を有する複数のチャンネル状野縁７とを、野縁受け４に取り付けられる野縁受け取付け部６１と、その垂下部６１ａの両端側に、逆Ｕ字状溝７１内に挿入させて野縁７を支持受けするよう上方に折曲された野縁係止片６２とを有する野縁固定金具６を介して支持するのであるが、本発明の野縁固定金具６は、野縁受け取付け部６１が、く字状に折曲形成され、その上部に、野縁受け４幅内の中間位置から上方に立ち上がり、立上り幅を２分位置で折曲変姿可能に形成された立上り片６３と、該立上り片６３から裏面側の野縁受け４に達するく字状に折曲する野縁受け挟持片６４を備えて構成され、野縁係止片６２を逆Ｕ字状溝７１内に挿入支持させた状態から、野縁受け取付け部６１を野縁受け４に面当て（既設固定金具５への間接面当てを含む）し、立上り片６３を野縁受け４の裏面側に押圧折曲させて野縁受け挟持片６４を野縁受け４に仮組付け可能とし、折曲されて対面する立上り片６３同士をビス固定することで、野縁受け取付け部６１と野縁受け挟持片６４とにより野縁受け４に挟持するように構成されている。 In the form of the embodiment of the present invention configured as described above, a plurality of field receivers 4 supported by the frame ceiling part 3 through the suspension members 2 and the inner sides of the upper end parts on both sides widened upward. A plurality of channel-shaped field edges 7 having inverted U-shaped grooves 71 are provided in the field-edge receiving attachment parts 61 to be attached to the field-edge receiver 4 and the opposite U-shaped grooves 71 in the opposite U-shaped grooves 71a. It is supported via a field edge fixing bracket 6 having a field edge locking piece 62 bent upward so as to support and receive the field edge 7. The field edge mounting portion 61 is bent in a square shape, and is formed on the upper part thereof so as to rise upward from an intermediate position within the width of the field edge receiver 4 so that the rising width can be bent at a position of 2 minutes. The rising piece 63 that has been formed, and a field that bends into a square shape that reaches the back edge side edge receiver 4 from the rising piece 63. From the state in which the receiving edge holding piece 64 is configured to be inserted and supported in the inverted U-shaped groove 71, the edge receiving portion 61 is brought into contact with the field receiving portion 4 (existing fixing bracket). 5), and the rising piece 63 is pressed and bent to the back surface side of the field edge receiver 4 so that the field edge holder clamping piece 64 can be temporarily assembled to the field edge receiver 4 and is bent. The rising pieces 63 facing each other are screw-fixed so as to be sandwiched by the field edge receiver 4 by the field edge receiver mounting portion 61 and the field edge receiver clamping piece 64.
この様に構成すると、シングル固定タイプの野縁固定金具６でありながら、挟込み固定タイプのものと同様の指圧変形不能な厚板材を採用することができ、野縁受け４への取り付けに当たっては、天井下地の新規施工は勿論、既設天井下地の補強工事であっても、野縁の既設固定金具５にセットして、折曲変姿可能に形成された立上り片６３を手で押圧するだけの簡単な操作で仮組付け固定が行え、この仮組付けした状態から、位置合わせ調整や対面する立上り片同士をビス止めする本固定作業が容易に行えるようになり、取付け作業を簡略化して、補強工事の作業性及び効率を向上させることができるばかりか、耐震機能を持たない単体で取り付けられた野縁７の既設固定金具５に対して、その表面を覆うように密着重合できるので、地震等の揺れを生じても、野縁受け取付け部６１と野縁受け挟持片６４とによって、既設取付け部５１を確実に外嵌狭圧して変形させた状態で、野縁受け４に対してしっかりと固定させた補強を行うことができ、ジョイント強度が向上されて、ガタツキ発生を防止しすることができると共に、隣接並設させた垂下部６１ａを含む野縁係止片６２が既設係止片５２の上下や横方向への変形応力を受け止めてその変形を抑止し、野縁７を逆Ｕ字状溝７１内で共同して支持受けできるようになり、その支持受け強度を向上させることができる。その結果、耐震補強用として用いられる野縁固定金具６だけでなく既設固定金具５自体にも耐震補強機能をもたせて、両者の共同作用により、天井下地全体の耐震強度を向上させることができる。 When configured in this manner, a thick plate material that cannot be deformed with finger pressure similar to that of the pinned and fixed type can be employed while being a single fixed type of field edge fixing bracket 6. In addition to new construction of the ceiling foundation, as well as reinforcement work for the existing ceiling foundation, it is set on the existing fixed bracket 5 on the edge and simply presses the rising piece 63 formed so that it can be bent and deformed. With this simple operation, the temporary assembly can be fixed, and from this temporarily assembled position, it is possible to easily perform the alignment adjustment and the final fixing work to fasten the rising pieces facing each other, simplifying the installation work. In addition to being able to improve the workability and efficiency of the reinforcement work, it can be closely polymerized so as to cover the surface of the existing fixing bracket 5 of the field edge 7 which is attached as a single unit having no earthquake resistance function, earthquake Even when the swaying occurs, the existing edge portion 51 is securely fitted to the edge edge receiver 4 in a state in which the existing edge portion 51 is securely fitted and deformed by the edge edge receiving portion 61 and the edge edge receiving pinching piece 64. The fixed reinforcement can be performed, the joint strength can be improved, the occurrence of rattling can be prevented, and the field edge locking piece 62 including the hanging portion 61a arranged adjacent to each other is provided with the existing locking piece 52. By receiving deformation stress in the vertical and lateral directions, the deformation can be suppressed, and the field edge 7 can be supported and received jointly in the inverted U-shaped groove 71, and the strength of the support and reception can be improved. . As a result, not only the field edge fixing bracket 6 used for seismic reinforcement but also the existing fixing bracket 5 itself can have a seismic reinforcement function, and the seismic strength of the entire ceiling base can be improved by the joint action of both.
つまり、既設の天井下地における野縁７の既設固定金具５を、野縁固定金具６を用いて具体的に耐震補強するには、野縁係止片６２を、その支持端部が既設係止片５２の支持端部と同一となるよう並設せしめて野縁７を支持受けするよう、既設係止片５２に背反して形成させておき、新設時と同様に、野縁係止片６２を逆Ｕ字状溝７１内に挿入支持させた状態から、野縁受け取付け部６１を、野縁受け４に表面側から裏面側に折曲されて取り付けられた既設取付け部５１に重合せしめ、立上り片６３同士を対向するビス孔６３ｂを介してビス固定することで、野縁受け取付け部６１と野縁受け挟持片６４とにより既設取付け部５１を外嵌して野縁受け４に挟圧させ、かつ、野縁係止片６２を、既設係止片５２と共同して隣接支持受けさせ、必要においてビス孔６１ｂ位置でドリルビスを用いて野縁受け４に固定することで、既設固定金具５を耐震補強すればよい。 That is, in order to concretely reinforce the existing fixing bracket 5 of the field edge 7 on the existing ceiling base using the field edge fixing bracket 6, the field edge locking piece 62 is fixed to the existing edge of the existing edge. In order to support and receive the field edge 7 in parallel with the support end of the piece 52, it is formed opposite to the existing locking piece 52, and the field edge locking piece 62 is formed in the same manner as in the new installation. Is inserted and supported in the inverted U-shaped groove 71, and the field edge receiving attachment 61 is superposed on the existing attachment 51 attached to the field edge receiving 4 by being bent from the front side to the back side, By fixing the rising pieces 63 to each other through the opposing screw holes 63b, the existing mounting portion 51 is externally fitted by the field edge receiving mounting portion 61 and the field edge receiving clamping piece 64 and is clamped to the field edge receiving 4 In addition, the field edge locking piece 62 is adjacently supported and received in cooperation with the existing locking piece 52. In By fixing the field edge receiving 4 with drill screws in screw holes 61b located may be Retrofit of existing fixing bracket 5.
この様に狭圧された既設取付け部５１は、図６（Ｂ）に示す如く、野縁受け４に密着変形され、ガタツキや位置ズレが確実に規制された状態で強固に固定され、既設取付け部５１に対する耐震補強を確実に行うことができる。そのため、地震等の揺れを生じて野縁受け４が幅方向へ振動負荷を生じた際に、野縁７は長手方向への振動負荷を受けることとなるが、図中、野縁７が左方向の横揺れを受けて既設係止片５２に振動負荷が生じても、隣接する垂下部６１ａが垂下部５１ａの振動応力を受け止めると共に、野縁係止片６２が既設係止片５２の略３倍の広幅な支持受け幅を有しており、この野縁係止片６２の野縁７への支持受け機能が発揮され、垂下部５１ａおよび既設係止片５２の変形を抑止し、特に、垂下部５１ａ側の支持受け機能を保持することができる。また、図中、野縁７が右方向の横揺れを受けた際には、野縁係止片６２だけで野縁７の振動負荷を受け止めることができ、既設係止片５２に何ら振動負荷が加わらず、これを回避することができ、既設固定金具５の野縁７への支持受け耐震強度を補強することができる。 As shown in FIG. 6 (B), the existing mounting portion 51 thus narrowed is tightly deformed to the edge receiver 4 and is firmly fixed in a state in which the backlash and the positional deviation are reliably regulated. Seismic reinforcement for the part 51 can be performed reliably. Therefore, when the field edge receiving 4 caused the earthquake shaking or the like occurs the vibration load in the width direction, ceiling joists 7 is a subject to vibration load in the longitudinal direction, in the drawing, ceiling joists 7 is left Even if a vibration load is generated on the existing locking piece 52 due to the rolling of the direction, the adjacent hanging part 61 a receives the vibration stress of the hanging part 51 a and the field edge locking piece 62 is an abbreviation of the existing locking piece 52. The support receiving width of the field edge locking piece 62 to the field edge 7 is demonstrated, and deformation of the hanging part 51a and the existing locking piece 52 is suppressed. The support receiving function on the hanging portion 51a side can be maintained. In addition, in the figure, when the field edge 7 is subjected to a horizontal roll, the vibration load of the field edge 7 can be received only by the field edge locking piece 62, and any vibration load is applied to the existing locking piece 52. Therefore, this can be avoided and the seismic strength of the support receiving to the field edge 7 of the existing fixture 5 can be reinforced.
また、野縁係止片６２は、野縁受け４の下面域側に配設すると共に、その支持受け幅を野縁受け４と略同幅寸法に設定して形成されているので、野縁受け４の略下面全域幅内で野縁受け４の下面域と野縁係止片６２との間で、逆Ｕ字状溝７１の上辺を挟み込んだ状態で野縁７を支持受けできるので、地震等の縦揺れや横揺れを生じても、両者間における共同挟持作用により、上下や横方向への変形応力を均等に受け止めてガタツキが規制され、支持受け状態を好適に維持することができ、耐震強度が向上された耐震構造を得ることができる。
このため、新設天井への使用は勿論、既設天井に適用して、野縁固定金具６を、既設固定金具５（既設係止片５２）が配設されていない側の野縁受け４に対向配設させて使用する場合でも、特に、野縁係止片６２を、既設係止片５２に近接または当接する幅寸法に形成して並設することができ、更に、両側野縁係止片６２間の幅を、両側既設係止片５２間の内法幅寸法に設定して既設係止片５２とオーバーラップさせ、両者の上端が重合して支持受けする状態で並設することが可能となる。その結果、地震等の揺れを生じて野縁受け４が幅方向へ振動負荷を生じた際に、野縁係止片６２が既設係止片５２を受け止めて変形を抑止すると共に、支持受け幅が既設係止片５２の略３倍の寸法を有する野縁係止片６２が主体となって野縁７を支持することができ、既設係止片５２への振動負荷を抑止し、既設固定金具５自体を補助してその支持受け機能を維持し得て、両者の共同作用により、天井下地全体の耐震強度を向上させることができる。
Further, the field edge locking piece 62 is disposed on the lower surface region side of the field edge receiver 4 and has a support receiving width set to be substantially the same width as the field edge receiver 4. Since the upper edge of the inverted U-shaped groove 71 is sandwiched between the lower surface area of the field edge receiver 4 and the field edge locking piece 62 within the substantially entire lower surface width of the receiver 4, the field edge 7 can be supported and received. Even if a pitching or rolling such as an earthquake occurs, the joint clamping action between the two allows the deformation stress in the vertical and horizontal directions to be received evenly and the backlash is restricted, and the support receiving state can be suitably maintained. An earthquake resistant structure with improved earthquake resistance can be obtained.
For this reason, it is applied to the existing ceiling as well as the new ceiling, and the field edge fixing bracket 6 is opposed to the field edge receiver 4 on the side where the existing fixing bracket 5 (the existing locking piece 52) is not provided. Even in the case of arranging and using, in particular, the field edge locking piece 62 can be formed side by side with a width dimension close to or in contact with the existing locking piece 52. It is possible to set the width between 62 to the internal width dimension between the existing locking pieces 52 on both sides and to overlap the existing locking pieces 52, and to arrange them in parallel with the upper ends of both overlapping and receiving. It becomes. As a result, when the field edge receiver 4 generates a vibration load in the width direction due to a shake such as an earthquake, the field edge locking piece 62 receives the existing locking piece 52 and suppresses deformation, and the support receiving width. However, it is possible to support the field edge 7 mainly by the field edge locking piece 62 having a size approximately three times as large as that of the existing locking piece 52, to suppress the vibration load on the existing locking piece 52, and to fix the existing locking piece 52. The support 5 can be maintained by assisting the metal fitting 5 itself, and the joint strength of both can improve the seismic strength of the entire ceiling foundation.
また、立上り片６３は、その２分位置となる折曲部６３ａの部位で略Ｌ字状に形成されており、折曲部６３ａは、両側に幅狭の連結片６３１を残して打ち抜き形成されているので、厚板材を用いても、野縁受け４への取付けに際し、手で折曲操作し安くなっている。 Further, the rising piece 63 is formed in a substantially L shape at a portion of the bent portion 63a which is a half position thereof, and the bent portion 63a is formed by punching leaving a narrow connecting piece 631 on both sides. Therefore, even if a thick plate material is used, when it is attached to the field edge receiver 4, it is bent by hand to make it cheaper.
また、野縁係止片６２は、それぞれ外方に傾斜せしめて逆ハ字状に形成されており、逆Ｕ字状溝７１内に挿入して野縁７を支持受けした際に、その上端となる板厚内側角部を線当接させて、野縁７の自重や天井パネル８の自重で長手方向への滑り止めが成されるべく構成されているので、従来の既設固定金具５の既設係止片５２を垂直に立ち上がり、その上端をＬ字状に形成し、板厚面を面当接させて支持受けしたものに比し、ガタツキ無く施工することができ、地震等の揺れを生じても、野縁係止片６２の上端となる板厚内側角部が、逆Ｕ字状溝７１内でその線当接して支持受けする機能により、野縁７の滑りや揺動を抑止し支持受けする位置ズレを効果的に防止することができ、耐震に対する支持受けの補強機能を向上させ、既設係止片５２の変形応力を受け止めてその変形を抑止しすることができる。 Each of the field edge locking pieces 62 is formed in an inverted C shape by being inclined outwardly, and when inserted into the inverted U-shaped groove 71 to receive and support the field edge 7, The inner corner portion of the plate thickness is brought into line contact with the weight of the field edge 7 and the weight of the ceiling panel 8 to prevent slipping in the longitudinal direction. The existing locking piece 52 stands up vertically, its upper end is formed in an L shape, and it can be constructed without rattling, compared to the case where the plate thickness surface is in contact with the surface, and it can be shaken, such as an earthquake. Even if it occurs, the inner edge of the plate thickness that becomes the upper end of the field edge locking piece 62 prevents the field edge 7 from slipping or swinging by the function of receiving and supporting the line U in the inverted U-shaped groove 71. It is possible to effectively prevent misalignment of the support receiving and improve the reinforcement function of the support receiving with respect to earthquake resistance, And receiving a second deformation stress can be suppressed that deformation.
また、野縁受け取付け部６１の垂下部６１ａの両端側をハ字状に傾斜する傾斜辺６１ｃに形成し、逆Ｕ字状溝７１を形成する野縁７の両折曲片７１ａの先端を、野縁の幅方向へのガタツキを規制すべく、傾斜辺６１ｃに沿って自重案内させて当接支持可能に構成されているので、両折曲片７１ａの先端は、結局、傾斜辺６１ｃと傾斜する野縁係止片６２とにより形成される略Ｖ字状の折曲片挿入溝６５で支持させることができる。したがって、従来の既設固定金具５の様に、垂下部５１ａの両側端部を垂直辺とし、既設係止片５２を垂直に立ち上がり形成させて、垂下部５１ａの垂直辺と既設係止片５２との間に形成される凹状挿入溝５３に、野縁７の折曲片７１ａを何ら支持することなく遊挿させて、野縁７を既設係止片５２だけで支持受けするようにしたものに比し、野縁７をその逆Ｕ字状溝７１内で野縁係止片６２により支持受けできるだけけでなく、野縁係止片６２の板厚内側角部が線当接されて長手方向への滑り止めが成される一方、野縁７の両折曲片７１ａの先端が、鉛直部両側の刃状の円弧傾斜辺６１ｃに沿って自重案内されて対向接当し、野縁７の幅方向へのガタツキを防止すると共に、野縁７の自重と天井パネル８の荷重により、野縁係止片６２と刃状の傾斜辺６１ｃにより形成されるＶ字状の折曲片挿入溝６５内間にしっかりと噛み込み係合して挟持され、野縁７の幅方向と長手方向への位置ズレが規制される位置決め機能を果たすことができ、既設係止片５２の変形応力を受け止めてその変形を抑止しすることができる。
In addition, both ends of the hanging portion 61a of the field edge receiving attachment portion 61 are formed in an inclined side 61c inclined in a C shape, and the ends of both folded pieces 71a of the field edge 7 forming the inverted U-shaped groove 71 are formed. In order to regulate the backlash in the width direction of the field edge, it is configured so that it can be guided and supported by its own weight along the inclined side 61c, so that the end of the double-folded piece 71a eventually becomes the inclined side 61c. It can be supported by a substantially V-shaped bent piece insertion groove 65 formed by the inclined field edge locking piece 62. Therefore, like the conventional fixing bracket 5, both end portions of the hanging part 51 a are set as vertical sides, and the existing locking pieces 52 are vertically formed so that the vertical sides of the hanging parts 51 a and the existing locking pieces 52 are The bent insertion groove 53 formed between them is loosely inserted without supporting the bent piece 71a of the field edge 7 so that the field edge 7 is supported and received only by the existing locking piece 52. In comparison, not only can the field edge 7 be supported and supported by the field edge locking piece 62 in the inverted U-shaped groove 71, but also the inner corner of the thickness of the field edge locking piece 62 is in line contact with the longitudinal direction. The tip of both bent pieces 71a of the field edge 7 is guided by its own weight along the blade-like circular arc inclined sides 61c on both sides of the vertical portion and is opposed to the edge of the field edge 7. While preventing backlash in the width direction, the edge lock piece 62 and the blade are cut by the weight of the edge 7 and the load of the ceiling panel 8. Positioning in which the gap between the V-shaped bent piece insertion groove 65 formed by the inclined side 61c is firmly engaged and engaged, and the positional deviation of the field edge 7 in the width direction and the longitudinal direction is restricted. The function can be fulfilled, and the deformation stress of the existing locking piece 52 can be received to suppress the deformation.
