Description
本発明は、天井下地において、野縁受けを両側から組みとして挟持することで、野縁を取り付けする野縁取付金具、および当該野縁の耐震補強構造に関する。
The present invention relates to a field edge mounting bracket for attaching a field edge by sandwiching a field edge receiver as a set from both sides in a ceiling base, and an earthquake-proof reinforcement structure for the field edge.
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Ｃ字状のリップ溝型材（又は、コ字状チャンネル材）を用いた野縁受けと、開口側を上方に向けて一組の野縁取付金具を介して野縁受けに取り付けされる複数のＣ字状のリップ溝型材（又は、上端内方に逆Ｕ字状溝を有したコ字状チャンネル材）を用いた野縁と、野縁にネジ（ボルト、ビスを含む）止めされる天井パネルとから構成される。 In general, a conventional ceiling is a field edge using a plurality of C-shaped lip groove members (or U-shaped channel members) supported on the ceiling of the housing via suspension members (such as suspension bolts and suspension wires). A plurality of C-shaped lip groove molds (or inverted U-shaped grooves on the inside of the upper end) attached to the field edge receiver through a pair of field edge mounting brackets with the opening facing upward. And a ceiling panel that is screwed to the field edge (including bolts and screws).
従来の天井下地に用いられる野縁取付金具は、指圧変形不能な板厚が約１．２〜１．６ｍｍの厚板材でプレス成型され、野縁受けに取り付けられるネジ固定用の立上り片を有する逆Ｌ字状の野縁受け取付け部と、下方に延出形成される垂下部に、野縁折曲片の裏面側に挿入して野縁を支持受けする野縁支持受け部とにより一体形成されたものを１組のセット金具として、野縁受けに両側から挟み込ませて対面する立上り片同士をボルト止め等により固定して野縁を吊持する構造となっており、野縁支持受け部も野縁受けの下面域側（内側）または野縁受けに背反する側（外側）に、任意に折曲形成した両側２カ所で野縁を支持受けすることで、所定の吊持強度やジョイント強度、耐震強度が得られる（特許文献１の図２、特許文献２の図１参照）。 A conventional edge mounting bracket used for a ceiling base is press-molded with a thick plate material having a thickness of about 1.2 to 1.6 mm that cannot be deformed with finger pressure, and has a rising piece for fixing a screw to be attached to a field receiving. Integrated with a reverse L-shaped field edge receiving part and a field edge support receiving part for supporting and receiving the field edge by inserting it on the back side of the field edge bent piece at the hanging part extending downward. As a set of metal fittings, it is sandwiched from both sides of the field edge receiver, and the rising pieces facing each other are fixed by bolting etc. to suspend the field edge. By supporting and receiving the field edge at two places on both sides, which are arbitrarily bent, on the lower surface area side (inside) or the side opposite to the field edge receiver (outside) Strength and seismic strength can be obtained (see Fig. 2 of Patent Document 1 and Fig. 1 of Patent Document 2) ).
ところで、この様な天井下地の構造においては、野縁受けの下面側と野縁の開口側が直接接触した状態で施工され、また、野縁受けの側面側に配設される野縁取付金具は、野縁受け取付け部が野縁受けの側面にネジ固定され、立上り片の締結ボルトとの上下２個所により支持固定されるが、野縁受けの開口側に配設されたものは締結ボルトによる１個所による支持固定となり、縁受けの開口側が上下方向へ圧縮されるような振動負荷を野縁受け取付け部のみで受けこととなる。このため、震等により揺れを受けた際、野縁の長手方向への振り子状の傾動やねじれなどを伴って、野縁受けの開口側が上下方向（内方）へ圧縮（狭圧）されるような振動負荷を受けて変形を生じたり、野縁支持受け部と野縁折曲片との間の滑りを生じるなどにより、野縁と野縁受けとの間にガタツキが発生して、両者間に位置ズレを誘発してしまうという問題があり、殊に、野縁受けの開口側においては、野縁受け取付け部（垂下部）が変形して、対向する野縁支持受け部同士が離間して開いてしまうなどの要因も加わって、野縁受け取付け部が野縁受けの側面にネジ固定された側に比し、耐震強度の性能が劣るという問題がある。 By the way, in such a ceiling base structure, it is constructed in a state where the lower surface side of the field edge receiver and the opening side of the field edge are in direct contact, and the field edge mounting bracket disposed on the side surface side of the field edge receiver is The field edge mounting part is screwed to the side surface of the field edge receiver, and is supported and fixed by two upper and lower parts with the fastening bolt of the rising piece. The support is fixed at one place, and the vibration load that compresses the opening side of the edge receiver in the vertical direction is received only by the field edge receiving attachment part. For this reason, when subjected to shaking due to an earthquake or the like, the opening side of the field edge receiver is compressed (narrow pressure) in the vertical direction (inward) with a pendulum-like tilt or twist in the longitudinal direction of the field edge. Such a vibration load causes deformation and / or sliding between the field edge support receiving part and the field edge bent piece, resulting in rattling between the field edge and the field edge receiver. There is a problem that misalignment is caused between them. Especially, on the opening side of the field edge receiver, the field edge support mounting part (hanging part) is deformed, and the opposite field edge support receiving parts are separated from each other. As a result, there is a problem that the seismic strength performance is inferior to the side where the field edge mounting portion is screwed to the side surface of the field edge receiver.
そこで、対向する野縁支持受け部（野縁支持片）同士が開いてしまうことを防止するため、特許文献１に開示されたものように、野縁支持片としての係止部（１１）間に固定基板（６）を配設して、係止部（１１）に穿設した窓孔部（１４）を介して、固定基板（６）に折曲形成したストッパー片（１３）を挿入係止することで、係止部（１１）同士の開きを防止している。しかしながら、このものは、窓孔部（１４）と係止部（１１）とが遊挿されており、かつ、野縁に予めネジ固定した固定基板（６）上に野縁受けを載置する構成であるため、野縁と野縁受けとが固定基板（６）の厚さ分だけ離間した状態で、野縁の長手方向への振り子状の傾動やねじれなどの振動負荷が加わると、野縁受け（３）と野縁（５）に同じ板厚のリップ溝型材が用いられており、この様な組合せにおいては野縁受け（３）の開口側がの変形を生じやすく、しかも、軸芯位置が一致するネジの固定位置を中心にかえって揺れが大きく作用し、野縁受けの開口側が固定基板（６）と野縁とによる圧縮負荷を受けて変形が誘発され、固定基板（６）と野縁受けとの間に滑りやガタツキが発生してしまうという問題がある。 Therefore, in order to prevent the opposing field edge support receiving parts (field edge support pieces) from opening, between the locking parts (11) as the field edge support pieces, as disclosed in Patent Document 1. The fixed substrate (6) is disposed on the stopper plate (13), and the stopper piece (13) bent on the fixed substrate (6) is inserted through the window hole (14) formed in the locking portion (11). By stopping, the opening of the locking portions (11) is prevented. However, in this case, the window hole portion (14) and the locking portion (11) are loosely inserted, and the field edge receiver is placed on the fixed substrate (6) fixed to the field edge in advance by screws. Because of the configuration, when a vibration load such as a pendulum-like tilt or twist in the longitudinal direction of the field edge is applied in a state where the field edge and the field edge receiver are separated by the thickness of the fixed substrate (6), Lip groove molds with the same plate thickness are used for the edge receiver (3) and the field edge (5). In such a combination, the opening side of the field edge receiver (3) is likely to be deformed, and the shaft core The vibration greatly acts around the fixed position of the screw with the matching position, and the opening side of the field edge receiver receives a compressive load by the fixed board (6) and the field edge to induce deformation, and the fixed board (6) There is a problem that slipping or rattling occurs between the paddle and the field guard.
また、特許文献２に開示されたものでは、補強フランジ部（３８）を有する野縁の係合突起（３２）を、野縁受けの下面域側（内側）に向けて折曲させて野縁を支持受けし、垂直基板部（３１）の一方に折曲形成したネジ止め突片（３４）を、野縁の側面にネジ固定するようにして、クリップ（３）が野縁から外れて落下してしまうことを防止している。また、コ字状チャンネル材の野縁受け（１）に比し板厚の薄い逆Ｕ字状溝を有したコ字状チャンネル材の野縁（５）が用いられており、この様な組合せにおいては野縁（５）が変形を生じやすい。しかしながら、このものは、その構造上、逆Ｕ字状溝内に挿入される係合突起（３２）が野縁受け（１）の下面側で支持受けし、かつ、垂直基板部（３１）が片面のみにしか形成することができず、殊に、垂直基板部（３１）が形成されていない側に、野縁（５）の長手方向への振り子状の傾動やねじれなどの振動負荷が加わると、野縁受け（１）の開口側が補強フランジ部（３８）と野縁（５）の逆Ｕ字状溝との両者によって圧縮負荷を受けることとなり、変形が誘発され野縁と野縁受けとの間に滑りやガタツキが発生してしまうという問題がある。
Moreover, in what was disclosed by patent document 2, the field edge engaging protrusion (32) which has a reinforcement flange part (38) was bent toward the lower surface area side (inner side) of a field edge receptacle, and a field edge The clip (3) falls off the field edge so that the screwing protrusion (34) bent on one side of the vertical substrate part (31) is screwed to the side surface of the field edge. To prevent it from happening. In addition, a U-shaped channel material field edge (5) having an inverted U-shaped groove that is thinner than the U-shaped channel material field edge receiver (1) is used. The field edge (5) tends to be deformed. However, in this structure, the engagement protrusion (32) inserted into the inverted U-shaped groove is supported and received on the lower surface side of the field edge receiver (1) and the vertical substrate portion (31) is structurally provided. It can be formed only on one side, and in particular, a vibration load such as a pendulum-like tilt or twist in the longitudinal direction of the field edge (5) is applied to the side where the vertical substrate part (31) is not formed. Then, the opening side of the field edge receiver (1) is subjected to a compressive load by both the reinforcing flange portion (38) and the inverted U-shaped groove of the field edge (5), and the deformation is induced to cause the field edge and the field edge receiver. There is a problem that sliding or rattling occurs between the two.
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、野縁受けの開口側に配設される野縁取付金具であっても、野縁取付金具自体のねじれや湾曲変形に対する剛性強度を高めることができ、震等により、野縁受けの開口側が上下方向へ圧縮されるような振動負荷を受けた際に、その湾曲変形を防止して野縁受けを耐震補強することができる結果、対向する野縁受け取付け部同士を通しネジにより締め付け固定して野縁受けに挟持組付けすることが可能となり、その開きを防止することができる野縁取付金具を提供することを目的とする。
The present invention has been devised to eliminate the above-described problems, and even if the field edge mounting bracket is disposed on the opening side of the field edge receiver, the field edge mounting bracket itself is twisted or curved. The strength against deformation can be increased, and when a vibration load is applied such that the opening side of the field receiver is compressed in the vertical direction due to earthquakes, the field receiver is seismically reinforced by preventing its bending deformation. As a result, it is possible to provide a field mounting bracket that can be clamped and fixed to the field receiver by tightening and fixing the opposing field receiver mounting portions to each other with a screw and preventing the opening thereof. With the goal.
上記課題を解決するために本発明の野縁取付金具は、吊り部材を介して躯体天井部に開口側を側方に向けて支持される複数のＣ字状又はコ字状の野縁受けと、開口側を上方に向けてその両側面の上端が内方に折曲された野縁折曲片を有する複数の野縁とを、１組の野縁取付金具を介して取り付けする天井下地において、前記野縁取付金具は、野縁受けの側面又は開口側に面当てされる野縁受け取付け部と、該野縁受け取付け部の上方に延出されて野縁受けの上面側に立上り形成される固定用の立上り片と、下方に延出形成される垂下部に、前記野縁折曲片の裏面側に挿入して野縁を支持受けする野縁支持受け部とを一体に備え、前記立上り片同士を対面当接させてボルト止め等により固定することで野縁を吊持するよう構成されると共に、前記組となる野縁取付金具は、野縁受けの側面側に配設される野縁受け側面側取付金具と、野縁受けの開口側に配設される野縁受け開口側取付金具とからなり、該野縁受け開口側取付金具の野縁受け取付け部には、その両側から野縁受けの上下開口幅と略同幅の長さを有して、野縁受けの開口内に挿入するよう折曲された野縁受け補強片を形成し、該野縁受け開口側取付金具は、野縁受けの開口内に挿入せしめた前記野縁受け補強片によって、野縁受けの開口側上下面に対する内方への圧縮振動負荷をその上下端で受け止め規制することで、野縁受けを耐震補強すべく構成してあることを特徴とするものである。
In order to solve the above-described problems, the field edge mounting bracket of the present invention includes a plurality of C-shaped or U-shaped field edge receivers that are supported on the casing ceiling portion with the opening side facing sideways through a suspension member. In a ceiling base for attaching a plurality of field edges having field edge bent pieces in which the upper ends of both side surfaces thereof are folded inward with the opening side facing upward, via a pair of field edge mounting brackets The field edge mounting bracket is formed with a field edge receiving part that faces the side surface or the opening side of the field edge receiving part, and is formed to rise above the field edge receiving attachment part and rise on the upper surface side of the field edge receiving part. The fixed rising piece to be formed, and a drooping portion formed to extend downward, are integrally provided with a field edge support receiving portion that is inserted into the back surface side of the field edge bent piece to support and receive the field edge, The rising pieces are brought into contact with each other and fixed by bolting or the like to suspend the field edge, and the front The pair of field edge mounting brackets is composed of a field edge receiving side surface mounting bracket disposed on the side surface of the field edge receiving member and a field edge opening side mounting bracket disposed on the field edge opening side. The field edge mounting portion of the field edge opening side mounting bracket has a length substantially the same as the width of the upper and lower openings of the field edge receiver from both sides thereof and is inserted into the opening of the field edge receiver. The bent edge receiving reinforcement piece is formed, and the edge receiving opening side mounting bracket is attached to the upper and lower surfaces on the opening side of the field receiving edge by the nose receiving reinforcement piece inserted into the opening of the field receiving. It is characterized in that the field receiver is configured to be seismically reinforced by receiving and restricting the inward compression vibration load at the upper and lower ends thereof.
本発明は、上記のように構成したことにより、天井下地における野縁受けに、その両側から一組の野縁取付金具を挟み込んで野縁を吊持するものでありながら、野縁受けの開口側に配設される野縁取付金具であっても、野縁受け取付け部に折曲形成された野縁受け補強片によって、野縁取付金具自体が補強され、ねじれや湾曲変形に対する剛性強度を高めることができると共に、地震等の揺れで水平方向やねじれ、傾斜方向の振動を受けた際に、野縁受けの開口側が上下方向へ圧縮されるような振動負荷を受けても、野縁受けの開口内に挿入された野縁受け補強片が、野縁受けの開口側上下面に対する内方への圧縮振動負荷を、その上下端で確りと受け止め支持する支持受け片として機能し、その湾曲変形を確実に防止して野縁受けを耐震補強することができ、野縁と野縁受けとの間のガタツキや野縁取付金具などの位置ズレを防止することができる。その結果、対向する縁受け取付け部同士を、通しネジを挿通して締め付け固定しても、締め付け過ぎや振動による野縁受け開口側取付金具（縁受け取付け部）の変形に対する剛性強度が高められ、両取付金具同士を野縁受けに確りと挟持させ、野縁受けに対する野縁支持受け部の離間や開き、滑りなどを規制して組付け剛性や耐震強度を高めることが可能となり、野縁受け補強片との共同耐震作用により、野縁支持受け部同士の振動による滑りや離間開きがより強固に防止されて、通しネジによる両者の締め付け挟持状態を長期に渡って保持することができる。
The present invention is configured as described above, so that a pair of field edge mounting brackets are sandwiched from both sides of the field edge receiver on the ceiling base so as to suspend the field edge. Even if the edge mounting bracket is arranged on the side, the field edge mounting bracket itself is reinforced by the field edge receiving reinforcing piece bent at the field edge receiving mounting portion, and the rigidity strength against torsion and bending deformation is increased. Even if it receives a vibration load that compresses the opening side of the field receiver in the vertical direction when it receives vibration in the horizontal direction, torsion, or tilt direction due to shaking such as an earthquake, the field edge receiver The edge receiving reinforcement piece inserted into the opening of the rim functions as a supporting receiving piece that firmly receives and supports the compressive vibration load inward with respect to the upper and lower surfaces of the opening on the opening side of the field receiving edge. Seismic compensation of field receivers by preventing deformation It can be, it is possible to prevent positional deviation, such as backlash or ceiling joist mounting bracket between the receiving ceiling joist and ceiling joists. As a result, even if the opposite edge receiving attachment parts are tightened and fixed by inserting through screws, the rigidity strength against deformation of the edge receiving opening side mounting bracket (edge receiving attachment part) due to excessive tightening or vibration is increased. The mounting brackets can be securely clamped between the edge supports and the mounting rigidity and seismic strength can be increased by regulating the separation, opening, and sliding of the edge support receiving part with respect to the field receiver. Due to the joint seismic action with the receiving reinforcement piece, the sliding and separation opening due to the vibration between the field edge support receiving portions is prevented more firmly, and the tightening and clamping state of both through screws can be maintained for a long time.

次に、本発明の実施態様に係る野縁取付金具６に並設される耐震補強部材７を図４の（Ａ）〜（Ｄ）に基づいて詳細に説明する。耐震補強部材７は、野縁支持受け部６３によって支持受けされた野縁５の支持受け構造を耐震補強するための部材であり、野縁受け３の横幅と略同幅の長さを有して、野縁受け３の開口側となる下側リップ片３ａ側と側面側を下面側から被嵌するよう、その上半部の中央面域に上向きコ字状に切欠きされた野縁受け被嵌溝部７１と、該野縁受け被嵌溝部７１の両側に延出して、野縁５の側面に面当てされてネジ固定される野縁固定部７２とを有して、全体が凹状の板状体にて形成される。野縁固定部７２には、野縁受け被嵌溝部７１の下部面にプレス成型された補強リブ７２ａが設けられており、その両側の任意位置に野縁５にドリルネジ９ｃにより固定するためのネジ孔７２ｂ、７２ｂが穿設されている。なお、本実施例におけるネジ孔７２ｂの穿設位置は、ドリルネジ９ｃなどを螺入した際に、そのネジ山が垂下部６１ｂの補強リブ６１ｄに近接または接触するように配設されており、野縁受け取付け部６１（野縁支持受け部６３）同士の振動による滑りや離間（拡開）規制に寄与し、ガタツキや位置ズレ、変形の発生を防止できるようになっている。 Next, the seismic reinforcement member 7 arranged in parallel with the field mounting bracket 6 according to the embodiment of the present invention will be described in detail based on (A) to (D) of FIG. The seismic reinforcement member 7 is a member for seismic reinforcement of the support receiving structure of the field edge 5 supported and received by the field edge support receiving part 63, and has a length substantially the same as the lateral width of the field edge receiver 3. The lower edge lip piece 3a, which is the opening side of the outer edge receiver 3, and the side edge of the upper edge portion of the upper edge portion of the lower edge lip piece 3a and the side surface side are fitted from the lower surface side. It has a fitted groove portion 71 and a field edge fixing portion 72 that extends to both sides of the field edge receiving groove portion 71 and is faced to the side surface of the field edge 5 and fixed by screws. It is formed of a plate-like body. The field edge fixing portion 72 is provided with a reinforcing rib 72a that is press-molded on the lower surface of the field edge receiving groove 71, and is a screw for fixing to the field edge 5 with a drill screw 9c at any position on both sides thereof. Holes 72b and 72b are formed. In this embodiment, the screw hole 72b is drilled so that when the drill screw 9c or the like is screwed in, the thread is close to or in contact with the reinforcing rib 61d of the hanging portion 61b. This contributes to slip and separation (expansion) regulation due to vibration between the edge receiving attachment portions 61 (field edge support receiving portions 63), and can prevent rattling, positional deviation, and deformation.
また、次に、本発明の実施態様に係る野縁取付金具６の取付手順について、図５、図６を参照して説明する。図５は野縁取付金具６と耐震補強部材７を天井下地への取付け状態を示す正面図、図５（Ｂ）は立上り片６２の他の固定手段を示す部分正面図であり、図６（Ａ）は図５の側面図、図６（Ｂ）は図５（Ｂ）の部分側面図である。これらの図に示すように、先ず、野縁受け開口側取付金具６ａと野縁受け側面側取付金具６ｂを、それぞれ野縁受け３の開口側と側面側の近傍位置で、野縁支持受け部６３を野縁５の長手方向に向けて野縁５の上側開口から内部に挿入して回転させ、野縁受け３の下面に位置する野縁折曲片５１の裏面に当接させ、係止部６１ａを野縁受け３の上面に面接させた状態で、上り片６２、６２の同士を対向面接させてセットする。 Next, a procedure for attaching the field edge fitting 6 according to the embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a front view showing a state in which the field edge fitting 6 and the seismic reinforcement member 7 are attached to the ceiling base, and FIG. 5B is a partial front view showing another fixing means of the rising piece 62. FIG. 6A is a side view of FIG. 5, and FIG. 6B is a partial side view of FIG. As shown in these drawings, first, the field edge support opening side mounting bracket 6a and the field edge receiving side surface side mounting bracket 6b are respectively positioned in the vicinity of the opening side and the side surface side of the field edge receiving member 3 at the field edge support receiving portion. 63 is inserted into and rotated from the upper opening of the field edge 5 in the longitudinal direction of the field edge 5, and is brought into contact with the back surface of the field edge bent piece 51 located on the lower surface of the field edge receiver 3. In a state where the portion 61a is in contact with the upper surface of the field receiver 3, the ascending pieces 62 and 62 are set to face each other.
次いで、両取付金具６ａと６ｂを手で保持した状態で、締結ボルト９をボルト挿通孔６２ａを介してナット部６２ｂに螺入操作することで、立上り片６２、６２の上端同士を当接させた状態で仮固定する。係止部６１ａは、内方に僅かに傾斜した状態で折曲形成され、立上り片６２も同様に内方に僅かに傾斜した状態となっており、この仮固定状態では、立上り片６２の上端同士が僅かなハ字状隙間を存して当接し、立上り片６２と係止部６１ａの角部が野縁受け３の上面に当接された状態でセットされる。この状態から更に締結ボルト９を締め付け操作していくと、立上り片６２、６２同士が僅かに変形しつつ圧着され、この圧着操作に追随して、係止部６１ａの角部側が野縁受け３の上面に押圧（圧接）されながら、両取付金具６ａと６ｂが僅かに上動して野縁支持受け部６３の上端が野縁折曲片５１の裏面に圧接係止されて、野縁受け３を両側から挟み込んで野縁５を吊持する固定がなされる。 Next, the upper ends of the rising pieces 62 and 62 are brought into contact with each other by screwing the fastening bolt 9 into the nut portion 62b through the bolt insertion hole 62a while holding both the mounting brackets 6a and 6b by hand. Temporarily fix in the state. The locking portion 61a is bent in a state slightly inclined inward, and the rising piece 62 is also slightly inclined inward. In this temporarily fixed state, the upper end of the rising piece 62 is formed. They are set in a state in which they are in contact with each other with a slight C-shaped gap and the corners of the rising piece 62 and the locking portion 61 a are in contact with the upper surface of the field edge receiver 3. When the fastening bolt 9 is further tightened from this state, the rising pieces 62 and 62 are pressure-bonded while being slightly deformed. Following this pressure-bonding operation, the corner portion side of the locking portion 61a is connected to the field edge receiver 3. Both mounting brackets 6a and 6b move slightly upward while being pressed (pressed) on the upper surface of the frame, and the upper end of the field edge support receiving portion 63 is pressed and locked to the back surface of the field edge bent piece 51, so that the field edge receiver 3 is sandwiched from both sides and fixed to suspend the field edge 5.
その際、野縁受け開口側取付金具６ａは、上側リップ片３ａに野縁受け補強片６４の上端が当接（僅かな間隙交差を有しても良い）する。次いで、従来のもののでは、野縁受け側面側取付金具６ｂをネジ孔６１ｃを介して短尺のドリルビスによりビス固定することで本固定状態がなされるのであるが、この様な固定方法を採用すると、野縁受け開口側取付金具６ａは、締結ボルト９による１点による支持固定となり、かつ、野縁受け３の開口側が上下方向へ圧縮されるような振動負荷を野縁受け取付け部６１のみで受けるため、締結ボルト９との２点により支持固定された野縁受け側面側取付金具６ｂに比して、その下方となる野縁支持受け部６３側の支持受けに対する組付け耐震強度の性能が劣り、滑りやガタツキ、変形などを生じ易いという問題が生じる。ところが本発明における野縁受け開口側取付金具６ａには、野縁受け補強片６４が形成されているので、対向する両垂下部６１ｂ、６１ｂのネジ孔６１ｃ、６１ｃ同士を介して通しネジ９ｂ（ドリルビスや締結ボルト）を挿通し、両者を締め付け固定しても、締め付け過ぎや振動による縁受け取付け部６１（垂下部６１ｂ）が挫屈等の変形を生じることが無く、両取付金具６ａと６ｂ（野縁支持受け部６３と６３）同士を野縁受け３に確りと挟持させ、両者の離間や開きを規制して組付け剛性や耐震強度が高めることが可能となる。 At that time, the upper edge of the field edge receiving reinforcing piece 64 is in contact with the upper lip piece 3a of the field edge opening side mounting fitting 6a (may have a slight gap crossing). Next, in the conventional one, this fixed state is made by screwing the field edge receiving side side mounting bracket 6b with a short drill screw through the screw hole 61c, but when such a fixing method is adopted, The field edge receiving opening side mounting bracket 6a is supported and fixed at one point by the fastening bolt 9, and receives the vibration load such that the opening side of the field edge receiving member 3 is compressed in the vertical direction only by the field edge receiving mounting part 61. Therefore, as compared with the field receiving side mounting bracket 6b supported and fixed by two points with the fastening bolt 9, the performance of the assembled seismic strength with respect to the support receiving on the side of the field supporting support 63 on the lower side is inferior. There arises a problem that slippage, rattling, deformation, etc. are likely to occur. However, in the field edge receiving opening side mounting bracket 6a according to the present invention, a field edge receiving reinforcing piece 64 is formed, so that a through screw 9b (through the screw holes 61c, 61c of the opposite hanging parts 61b, 61b is provided. Even if a drill screw or a fastening bolt is inserted and the both are tightened and fixed, the edge receiving mounting portion 61 (hanging portion 61b) is not deformed such as buckling due to excessive tightening or vibration, and both mounting brackets 6a and 6b The (field edge support receiving portions 63 and 63) can be securely held by the field edge receiver 3, and the separation and opening of both can be regulated to increase the assembly rigidity and the earthquake resistance.
また、締結ボルト９に換えて、図５（Ｂ）、図６（Ｂ）に示す如く、立上り片６２に所定間隔を存して穿設された２個所のネジ孔６２１、６２１に、ドリルネジ９ａ、９ａを用いてネジ固定するようにしても良い。この様に立上り片６２の所定間隔を存して両側２個所にネジ固定することにより、野縁受け３の長手方向に揺れを受けた際に、締結ボルト９を中心に回動方向への力が加わり、回転ズレによる締結ボルト９の緩みなどを生じてしまうことが回避され、野縁受け補強片６４による野縁５の長手方向やねじれ、傾斜方向に対する耐震補強機能との共同作用により、野縁５と野縁受け３との間にガタツキや、両者間の位置ズレの発生の防止機能に対して更なる向上を図ることができる。 Further, in place of the fastening bolt 9, as shown in FIGS. 5B and 6B, drill screws 9a are inserted into two screw holes 621 and 621 drilled in the rising piece 62 at a predetermined interval. , 9a may be used to fix the screws. In this way, by fixing the screws at two positions on both sides with a predetermined interval between the rising pieces 62, when the field receiver 3 is swayed in the longitudinal direction, the force in the rotational direction around the fastening bolt 9 is obtained. And the loosening of the fastening bolt 9 due to rotational displacement is avoided, and the joint action of the field edge receiving reinforcement piece 64 with the seismic reinforcement function in the longitudinal direction, twisting, and inclination direction of the field edge 5 It is possible to further improve the function of preventing the occurrence of rattling between the edge 5 and the field edge receiver 3 and the positional deviation between the two.
さらに、本実施例においては、この様に野縁支持受け部６３によって支持受けされた野縁５の支持受け構造を耐震補強するために耐震補強部材７が並設される。耐震補強部材７を取り付けするには、先ず、野縁受け被嵌溝部７１を野縁受け３の下面側に被嵌させた状態で、野縁５の側面に面当てして、ネジ孔７２ｂ、７２ｂを介してネジ固定すれば取付作業が完了する。野縁受け被嵌溝部７１は野縁５の両側面にそれぞれ配置固定されている。
この様に耐震補強部材７を並設すると、野縁受け補強片６４の耐震共同作用により、ねじれ方向を含む振動負荷をしっかりと受け止め、直交して直接面当て配設された野縁５と野縁受け３同士、および野縁５と野縁支持受け部６３同士の振動による滑りや離間、ガタツキ、位置ズレを確実に防止して、野縁５と野縁受け３との直交する密着状態を長期に亘って維持し、天井下地全体の耐震強度を向上させすることができる。
Further, in the present embodiment, the earthquake-resistant reinforcing member 7 is arranged in parallel in order to seismically reinforce the support receiving structure of the field edge 5 supported and received by the field edge support receiving portion 63 in this way. In order to attach the seismic reinforcement member 7, first, the field edge receiving groove 71 is applied to the side surface of the field edge 5 in a state where the field edge receiving groove 71 is fitted to the lower surface side of the field edge receiver 3, and screw holes 72b, If the screw is fixed via 72b, the mounting operation is completed. The field edge receiving groove portions 71 are arranged and fixed on both side surfaces of the field edge 5, respectively.
When the seismic reinforcement members 7 are arranged side by side in this way, the vibration load including the torsional direction is firmly received by the seismic joint action of the field edge reinforcement piece 64, and the field edge 5 and the field area arranged in direct contact with each other perpendicularly Slip, separation, rattling, and positional displacement due to vibration between the edge receivers 3 and between the field edge 5 and the field edge support receiving part 63 are surely prevented, and the perpendicular contact state between the field edge 5 and the field edge receiver 3 is prevented. It can be maintained over a long period of time and the seismic strength of the entire ceiling foundation can be improved.
叙述の如く構成された本発明の実施の形態において、いま、天井下地の施工において、野縁５を一組の野縁取付金具６（６ａ、６ｂ）を介して野縁受け３に取り付けるのであるが、本発明にかかる野縁取付金具６は、野縁受け３の側面又は開口側に面当てされる野縁受け取付け部６１と、野縁受け取付け部６１の上方に延出されて野縁受け３の上面側に立上り形成される固定用の立上り片６２と、下方に延出形成される垂下部６１ｂに、野縁折曲片５１の裏面側に挿入して野縁５を支持受けする野縁支持受け部６３とを一体に備え、立上り片６２、６２同士を対面当接させてボルト止め等により固定することで野縁５を吊持するよう構成されると共に、組となる野縁取付金具６は、野縁受け３の側面側に配設される野縁受け側面側取付金具６ｂと、野縁受け３の開口側に配設される野縁受け開口側取付金具６ａとからなり、該野縁受け開口側取付金具６ａの野縁受け取付け部６１には、その両側から野縁受け３の上下開口幅と略同幅の長さを有して、野縁受け３の開口内に挿入するよう折曲された野縁受け補強片６４を形成し、該野縁受け開口側取付金具６ａは、野縁受け３の開口内に挿入せしめた野縁受け補強片６４によって、野縁受け３の開口側上下面に対する内方への圧縮振動負荷をその上下端で受け止め規制することで、野縁受け３を耐震補強すべく構成されている。 In the embodiment of the present invention configured as described above, the field edge 5 is now attached to the field edge receiver 3 via a set of field edge mounting brackets 6 (6a, 6b) in the construction of the ceiling foundation. However, the field edge mounting bracket 6 according to the present invention includes a field edge receiving attachment part 61 that faces the side surface or the opening side of the field edge receiving member 3 and a field edge that extends above the field edge receiving attachment part 61. A fixed rising piece 62 that rises on the upper surface side of the receiver 3 and a hanging portion 61b that extends downward are inserted into the back surface side of the field bent piece 51 to support and receive the field edge 5. The field edge support receiving part 63 is integrally provided, and the rising edges 62 and 62 are brought into face-to-face contact and fixed by bolting or the like, so that the field edge 5 is suspended and the field edge to be paired The mounting bracket 6 is mounted on the side surface side of the field receiver 3. And a field edge receiving opening side mounting bracket 6a disposed on the opening side of the field edge receiving member 3, and the field edge receiving mounting portion 61 of the field edge receiving opening side mounting member 6a has a field edge from both sides thereof. A field edge receiving reinforcing piece 64 having a length substantially the same as the upper and lower opening width of the receiver 3 and bent to be inserted into the opening of the field receiver 3 is formed. The metal fitting 6a receives and regulates the compression vibration load inward with respect to the opening side upper and lower surfaces of the field edge receiver 3 at the upper and lower ends thereof by the field edge reinforcement piece 64 inserted into the opening of the field edge receiver 3. The field guard 3 is configured to be seismically reinforced.
この様に構成すると、天井下地における野縁受け３に、その両側から一組の野縁取付金具６を挟み込んで野縁５を吊持するものでありながら、野縁受け側面側取付金具６ｂに比して、その下方となる野縁支持受け部６３側の支持受けに対する組付け耐震強度の性能が劣り、滑りやガタツキ、変形などを生じ易い野縁受け開口側取付金具６ａであっても、野縁受け取付け部６１に折曲形成された野縁受け補強片６４によって、野縁受け開口側取付金具６ａ自体が補強され、ねじれや湾曲変形に対する剛性強度を高めることができる。
したがって、地震等の揺れで水平方向やねじれ、傾斜方向の振動を受けた際に、野縁受け３の開口側が上下方向へ圧縮されるような振動負荷を受けても、野縁受け３の開口内に挿入された野縁受け補強片６４が、野縁受け３の開口側上下面に対する内方への圧縮振動負荷を、その上下端で確りと受け止め支持する支持受け片として機能し、その湾曲変形を確実に防止して野縁受け３を耐震補強することができ、野縁５と野縁受け３との間のガタツキや野縁取付金具６などの位置ズレを防止することができる。
With this configuration, a pair of field edge mounting brackets 6 are sandwiched from both sides of the field edge receiver 3 on the ceiling base and the field edge 5 is suspended. Compared to the lower edge support receiving portion 63 side support receiver, the assembled seismic strength performance is inferior, and even the edge receiving opening side mounting bracket 6a that easily causes slipping, rattling, deformation, etc. The field edge receiving opening mounting bracket 6a itself is reinforced by the field edge receiving reinforcing piece 64 formed by bending the field edge receiving mounting part 61, and the rigidity strength against torsion and bending deformation can be increased.
Therefore, even if a vibration load is applied such that the opening side of the field edge receiver 3 is compressed in the vertical direction when subjected to vibrations in the horizontal direction, torsion, and inclination direction due to shaking such as an earthquake, the opening of the field edge receiver 3 The edge receiving reinforcement piece 64 inserted into the inside functions as a support receiving piece that firmly receives and supports the inward compression vibration load on the upper and lower surfaces of the opening on the opening side of the field receiving receiver 3, and its curvature Deformation can be reliably prevented and the field edge receiver 3 can be seismically reinforced, and rattling between the field edge 5 and the field edge receiver 3 and displacement of the field edge mounting bracket 6 can be prevented.
その結果、対向する両者のネジ孔６１ｃ、６１ｃ同士を通しネジ９ｂで締め付け固定しても、締め付け過ぎや振動による縁受け取付け部６１の変形に対する剛性強度が高められ、両取付金具６ａと６ｂ同士を野縁受け３に確りと挟持させ、両者の離間開きを規制して組付け剛性や耐震強度が高めることが可能となり、野縁受け補強片６４との共同耐震作用により、野縁支持受け部６３、６３同士の振動による滑りや離間開きがより強固に防止されて、野縁受け取付け部６１（垂下部６１ｂ）が圧縮振動負荷により湾曲変形などを生じることが回避され、通しネジによる両者の締め付け挟持状態を長期に渡って保持することができる。
しかも、この様に野縁支持受け部６３、６３によって支持受けされた野縁５の支持受け構造を耐震補強部材７によって耐震補強するにあたり、耐震補強部材７は、既に、野縁受け開口側取付金具６ａ自体が補強され、圧縮振動負荷を受ける野縁受け３の開口側における湾曲変形の防止や、通しネジ９ｂによる野縁支持受け部６３、６３同士の振動による離間開きの防止が図られた支持受け構造に採用されるので、直交して直接面当て配設された野縁５と野縁受け３同士、および野縁５と野縁支持受け部６３同士の振動による滑りや、ガタツキ、位置ズレを防止して直角度を維持できる機能に特化した、所謂、野縁受け被嵌溝部７１を有した凹状の板材であればよく、極めて簡易な構成のものとして製作することができる。
As a result, even if both screw holes 61c, 61c facing each other are tightened and fixed with screws 9b, the rigidity strength against deformation of the edge receiving mounting portion 61 due to excessive tightening or vibration is increased, and both mounting brackets 6a and 6b are connected to each other. Can be securely clamped by the field edge receiver 3, and the separation opening of both can be regulated to increase the assembly rigidity and the earthquake resistance. 63 and 63 are prevented more securely from sliding and separating apart, and it is avoided that the field edge mounting portion 61 (hanging portion 61b) is bent and deformed by a compressive vibration load. The clamped state can be held for a long time.
In addition, when the support receiving structure of the field edge 5 supported and received by the field edge support receiving parts 63 and 63 is seismically strengthened by the earthquake resistance reinforcing member 7, the earthquake resistance reinforcing member 7 has already been attached to the field edge opening side. The metal fitting 6a itself is reinforced to prevent bending deformation on the opening side of the field edge receiver 3 that receives a compressive vibration load, and to prevent separation opening due to vibration of the field edge support receiving parts 63 and 63 by the through screw 9b. Since it is employed in the support receiving structure, slipping, rattling, and position due to vibrations between the field edge 5 and the field edge receiver 3 and the field edge 5 and the field edge support receiving portion 63 that are disposed in direct contact with each other in an orthogonal manner. A concave plate material having a so-called field edge receiving groove portion 71 specialized in the function of preventing the deviation and maintaining the squareness can be used, and can be manufactured with a very simple configuration.
また、野縁受け側面側取付金具６ｂと縁受け開口側取付金具６ａとは、それぞれの野縁受け取付け部６１、６１同士を通しネジ９ｂにより締め付け固定させて、野縁受け３に挟持してあるので、野縁受け側面側取付金具６ｂの野縁受け取付け部６１（垂下部６１ｂ）は、野縁受け３の側面にネジ固定された密着状態で、野縁受け補強片６４、６４によって補強された野縁受け取付け部６１に螺入された通しネジ９ｂにより、野縁受け開口側取付金具６ａを野縁受け３の開口側（本実施例ではリップ片３ａ、３ａ側）に引き寄せした圧接状態で締め付け固定することができ、両取付金具６ａと６ｂ同士を野縁受け３に確りと挟持させ、両者の離間開きを規制して組付け剛性や耐震強度が高めることができるだけでなく、締め付け過ぎや振動による縁受け取付け部６１（垂下部６１ｂ）の挫屈等の変形を生じることも回避できる。 Further, the field edge receiving side surface mounting bracket 6b and the edge receiving opening side mounting bracket 6a are clamped and fixed to the field edge receiver 3 through the respective field edge receiving mounting portions 61, 61 through screws 9b. Therefore, the field edge receiving attachment portion 61 (the hanging part 61b) of the field edge receiving side surface side mounting bracket 6b is reinforced by the field edge receiving reinforcing pieces 64 and 64 in a close contact state fixed to the side surface of the field edge receiving 3 with screws. Press contact in which the field edge receiving opening side mounting bracket 6a is pulled toward the opening side of the field edge receiving 3 (in this embodiment, the lip piece 3a, 3a side) by a through screw 9b screwed into the field edge receiving attaching part 61 It can be fastened and fixed in a state where both mounting brackets 6a and 6b are securely clamped between the edge receivers 3 and the separation opening of both is restricted to increase assembly rigidity and seismic strength. Due to overshoot and vibration Can be avoided to cause deformation such as buckling of the edge receiving the mounting portion 61 (depending portion 61b).
