Description
本発明は、主に、耐震性が求められる建物の天井下地に用いられ、野縁取付金具を介して組付けられた野縁受けと野縁との組付け構造を補強することで、両者の組付け剛性強度を高めて耐震強度を向上することのできる耐震補強金具に関する。
The present invention is mainly used for a ceiling foundation of a building that requires earthquake resistance, and by reinforcing the assembling structure of the field edge receiver and the field edge assembled via the field edge mounting bracket, The present invention relates to a seismic reinforcing metal fitting that can improve the seismic strength by increasing the assembly rigidity strength.
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、上方に開口した両側面部の上端内方に逆Ｕ字状溝を有し、野縁取付金具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によって構築される天井下地によって構成される。
かかる天井下地における野縁は、野縁取付金具に形成された逆Ｕ字状溝内に挿入される野縁支持受け部によって支持受けされた構成となっており、地震等の揺れを受けた際に、その振動負荷により、野縁支持受け部が逆Ｕ字状溝から離間して変形を生じたり、野縁が野縁受けや野縁取付金具よりも薄板材で形成され、これらに比して強度的に弱いものである場合には、逆Ｕ字状溝の部位に変形を生じるなどして、野縁受けと野縁との間にガタツキが生じ、野縁取付金具などが位置ズレしてしまい、その様な状態で更なる振動を受けると、ガタツキや位置ズレが増大されて、天井下地全体が歪んだり、天井パネルの脱落につながる惧れがある。
In general, the conventional ceiling is inverted to the upper end inward of the plurality of field receivers (channel materials) supported by the frame ceiling portion via suspension members (suspending bolts, suspension wires, etc.) and the side surfaces opened upward. It has a U-shaped groove and is composed of a ceiling base constructed by a plurality of channel-shaped field edges supported by the field edge receiver via field edge mounting brackets, and a ceiling panel screwed to the field edge The
The field edge in the ceiling base is configured to be supported and received by a field edge support receiving part inserted into an inverted U-shaped groove formed in the field edge mounting bracket. In addition, due to the vibration load, the field edge support receiving part is separated from the inverted U-shaped groove and deformed, or the field edge is formed of a thin plate material than the field edge receiver or the field edge mounting bracket. If it is weak in strength, the reverse U-shaped groove part will be deformed, causing looseness between the field edge receiver and the field edge, and the field edge mounting bracket will be misaligned. Therefore, if further vibration is received in such a state, rattling and positional deviation are increased, and the entire ceiling base may be distorted or the ceiling panel may fall off.
そこで、近年、この様な天井下地において、既設、新設を問わずその耐震性を向上するために、特許文献１や２に開示されたもののように、野縁取付金具全体を補強する野縁の耐震補強構造や、野縁支持受け部による野縁の支持受け構造を補強する耐震補強金具なるものが提案されている。
すなわち、特許文献１のものは、耐震強度の劣る指圧変形可能な薄板材で形成された既設のシングル固定タイプの野縁取付金具（５）に対して、その表面全体を覆うように密着重合することのできる指圧変形不能な厚板材にて形成された新たな野縁取付金具（６）を外嵌して野縁受け（４）に挟圧させ、野縁係止片（６２）を、既設係止片（５２）と共同して逆Ｕ字状溝（７１）を隣接支持受けする構成によって耐震補強する構造となっている。
しかしながら、このものは、既設の野縁取付金具（５）自体の変形を規制し、野縁（７）を逆Ｕ字状溝（７１）内で共同して支持受けできるものの、依然として逆Ｕ字状溝（７１）に依存した支持受け構造を補強するものであるため、野縁（７）が薄板材であるが故に、傾動等を伴う振動負荷が加わった際に、支持受け部位となる逆Ｕ字状溝（７１）の変形や、直交する交差角度ズレを生じ、ガタツキや位置ズレを生じる危惧があるだけでなく、挟込み固定タイプのものを含め、耐震強度を有する指圧変形不能な厚板材で形成された野縁取付金具が用いられた天井下地に採用することができないという問題がある。
Therefore, in recent years, in such a ceiling foundation, in order to improve the earthquake resistance regardless of whether it is an existing installation or a new installation, as in those disclosed in Patent Documents 1 and 2, a field edge that reinforces the entire field edge mounting bracket is used. A seismic reinforcing structure or a seismic reinforcing metal fitting that reinforces the support support structure of the field edge by the field support support part has been proposed.
That is, the thing of patent document 1 carries out close_contact | adherence superposition | polymerization so that the whole surface may be covered with respect to the existing single fixed type field edge mounting bracket (5) formed with the thin plate material which can be deformed by acupressure with inferior seismic strength. A new field edge fitting (6) formed of a thick plate material that cannot be deformed with finger pressure can be externally fitted and clamped by the field edge receiver (4), and the field edge locking piece (62) is installed. The structure is such that the inverted U-shaped groove (71) is adjacently supported and received in cooperation with the locking piece (52) and is seismically reinforced.
However, although this restricts deformation of the existing field edge fitting (5) itself and can jointly receive the field edge (7) in the inverted U-shaped groove (71), it is still inverted U-shaped. Since the support receiving structure depending on the groove (71) is reinforced, since the field edge (7) is a thin plate material, when the vibration load accompanied by tilting or the like is applied, the reverse becomes a support receiving part. Not only is there a risk of deformation of the U-shaped groove (71) or crossing angle at right angles, which may cause rattling or misalignment, but it also has a seismic strength, such as a pinch-fixed type, and cannot be deformed with acupressure. There is a problem in that it cannot be used for a ceiling base using a field edge mounting bracket formed of a plate material.
一方、特許文献２のものは、特許文献１のような支持受け部位となる逆Ｕ字状溝（７１）の振動負荷による変形を規制するために、野縁（７）に固定される野縁被嵌部（６１）と、野縁（７）の逆Ｕ字状溝（７１）間に介在され、野縁被嵌部（６１）から内方に折曲されて、野縁支持受け部（５２）の下面域を覆ってその振動を規制する傾動規制部（６２）とを一体的に備えた耐震補強金具（６）を取り付けすることによって、野縁取付金具（５ａ）の支持受け部位に対する耐震強度を向上させる補強を行うことができるようにしている。
しかしながら、野縁支持受け部（５２）の部位のみを野縁被嵌部（６１）により野縁（７）に被嵌補強したものでは、特許文献１のものと同様に、逆Ｕ字状溝（７１）に依存した支持受け構造を補強するものであるため、殊に、シングル固定タイプの野縁取付金具が用いられた天井下地においては、野縁（７）の長手方向への振り子状の傾動やねじれなどを伴う振動負荷が加わった際に、野縁（７）と野縁受け（４）の下面域との離間や、直交する交差角度ズレを生じてしてしまうだけでなく、野縁（７）が薄板材であるが故に、挟込み固定タイプのものを含め、野縁受け（４）下面の押圧負荷を受けて、補強されない当該部位の逆Ｕ字状溝（７１）や両側面域に変形を生じる危惧がある。しかも、かかる耐震補強金具（６）を耐震強度の劣る指圧変形可能な薄板材で形成された野縁取付金具に採用することができないという問題がある。
On the other hand, the thing of patent document 2 is a field edge fixed to a field edge (7) in order to control the deformation | transformation by the vibration load of the inverted U-shaped groove | channel (71) used as a support receiving part like patent document 1. It is interposed between the fitted portion (61) and the inverted U-shaped groove (71) of the field edge (7), bent inward from the field edge fitted portion (61), and the field edge support receiving portion ( 52) by attaching an anti-seismic reinforcement bracket (6) that integrally includes a tilt regulating portion (62) that covers the lower surface area and regulates its vibration, to the support receiving part of the field edge mounting bracket (5a). Reinforcement that improves seismic strength can be performed.
However, in the case where only the portion of the field edge support receiving portion (52) is fitted and reinforced to the field edge (7) by the field edge fitted portion (61), the inverted U-shaped groove is the same as that of Patent Document 1. Since the support receiving structure depending on (71) is reinforced, the pendulum-like shape in the longitudinal direction of the field edge (7) is used particularly in a ceiling foundation using a single fixed type field edge mounting bracket. When a vibration load accompanied by tilting or twisting is applied, not only the separation between the field edge (7) and the lower surface area of the field edge receiver (4), but also the crossing angle deviation perpendicular to each other occurs. Since the edge (7) is a thin plate material, the inverted U-shaped groove (71) and both sides of the part that is not reinforced by receiving the pressure load on the lower surface of the field edge receiver (4) including those of the pinned and fixed type There is a risk of deformation in the surface area. In addition, there is a problem that such a seismic reinforcement bracket (6) cannot be employed in a field edge mounting bracket formed of a thin plate material that is inferior in seismic strength and can be deformed with acupressure.
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、野縁を、その逆Ｕ字状溝内に挿入される野縁支持受け部によって支持受けすることで、野縁取付金具を介して野縁受けに組付けされた構造を補強するものでありながら、当該野縁支持受け部による野縁の支持受け構造を利用し、かつ、当該野縁取付金具自体やその支持受け構造に依存しない独立一体化した組付け構成をもって、野縁の周辺域を含め、縁受けと野縁との組付け剛性強度を高め、シングル固定タイプや挟込み固定タイプ、指圧変形が可能・不能などの如何にかかわらず、種々の野縁取付金具が用いられた天井下地に採用することのでき、しかも、地震等の揺れにより、前後左右等に傾動する振動負荷を受けた際に、野縁受け等他の部材よりも薄板にて形成される野縁自体のねじれや変形を防止して、両者間の密着状態を好適に保持し、野縁固定金具への振動負荷による影響を減少または回避することができ、野縁受けと野縁との間のガタツキや位置ズレを防止し、直角度を維持することのできる耐震補強金具を提供することを目的とする。
The present invention was devised to eliminate the above-mentioned problems, and the field edge is supported and received by a field edge support receiving portion inserted into the inverted U-shaped groove, thereby providing a field edge. While reinforcing the structure assembled to the field edge receiver via the mounting bracket, the field edge support receiving structure by the field edge support receiving part is used, and the field edge mounting bracket itself and its support are used. With an independently integrated assembly structure that does not depend on the receiving structure, the mounting rigidity strength between the edge receiver and the field edge including the peripheral area of the field edge is increased, and the single fixed type, pinched fixed type, and acupressure deformation are possible. Regardless of whether it is impossible or not, it can be used for ceiling bases with various field edge mounting brackets, and when subjected to a vibration load that tilts forward, backward, left, right, etc. due to earthquakes, etc. It is formed of a thin plate than other members such as edge holders. By preventing twisting and deformation of the field edge itself, it is possible to favorably maintain a close contact state between them, and to reduce or avoid the influence of vibration load on the field edge fixing bracket. An object of the present invention is to provide an anti-seismic reinforcing metal fitting that can prevent rattling and misalignment and maintain a squareness.

As shown in these figures, the seismic reinforcing metal fitting 7 is formed by press molding with a thick plate material having a plate thickness of 1.2 to 1.6 mm, and is formed so as to cover the field edge receiving mounting portion 61 so as to face the edge edge receiving covering portion 61. 71 and a pair of field edge receiving fitting fixing parts 72, 72 extending in both sides of the field edge receiving covering part 71 and formed in a U shape in a side view and externally fitted to the field edge receiver 3. And a pair of field-fitting insertion fixing parts 73, which are bent in an L shape on the lower surface pieces 723 of the field edge receiving and fixing parts 72, 72, and are respectively face-fitted to both side surfaces of the field edge 5. 73 is integrally provided.
野縁受け被覆部７１は、野縁受け取付け部６１に被覆した際に、非接触状態で対向離間するよう、野縁取付金具６の横幅よりも広幅で、野縁受け３の縦幅よりも幅狭な板体の両端を円弧状に湾曲折曲させた、平面視凹状（倒伏〔状）に形成されており、その中央部には、野縁受け取付け部６１が野縁受け３の側面にネジ固定されている場合に、ネジ頭が当接しないように縦長小判状のバカ孔７１ａが穿設されている。バカ孔７１ａの上方に形成された円弧面は、バカ孔７１ａの孔径の大きさ（形状）に付随して補強用に形成される。つまり、野縁受け被覆部７１の野縁受け３の側面と離間する凹状幅は、種々の野縁取付金具６の形状の違いによって、野縁受け３に取着された野縁受け取付け部６１の膨出幅が異なっていても、野縁受け嵌装固定部７２を野縁受け３の側面に面当て被嵌した際に、非接触状態で被覆できるようになっている。 The field edge receiving cover 71 is wider than the lateral width of the field edge mounting bracket 6 and is larger than the vertical width of the field edge receiving 3 so as to face and separate in a non-contact state when the field edge receiving attachment 61 is covered. Both ends of the narrow plate body are bent in a circular arc shape, and are formed in a concave shape (inclined [shape] in plan view). A vertical oblong hole 71a is formed so that the screw head does not come into contact with the screw. The circular arc surface formed above the fool hole 71a is formed for reinforcement in association with the size (shape) of the hole diameter of the fool hole 71a. In other words, the concave width of the field edge receiving cover 71 that is separated from the side surface of the field edge receiver 3 is different from the shape of the various field edge mounting brackets 6 so that the field edge receiver mounting part 61 attached to the field edge receiver 3 is used. Even if the bulge widths of the two are different, when the field edge receiving and fixing portion 72 is fitted to the side surface of the field edge receiver 3, it can be covered in a non-contact state.
野縁受け嵌装固定部７２は、野縁受け被覆部７１の表面から面落ちするよう、その円弧端から延出形成され、野縁受け取付け部６１との接触を回避するよう、その両側となる野縁受け３の側面に直接面当てされてネジ固定される野縁受け固定片７２１と、その上端にＬ字状に折曲形成されて野縁受け３の上面に係止される上面片７２２と、下端にＬ字状に折曲形成されて野縁受け３の下面を支持受け状に係止する下面片７２３とを有して、側面視コ字状に一体形成される。上面片７２２は、野縁受け３の上面幅（厚さ幅）よりも短めの幅（長くても良い）をもって形成されており、下面片７２３は、その先端側を、野縁受け３の下面域を通過する長さ幅をもって延出形成されている。また、野縁受け固定片７２１の略中央の野縁５寄りにネジ孔７２ａが穿設されている。 The field edge receiving and fixing portion 72 is formed to extend from the end of the arc so as to fall from the surface of the field edge receiving covering portion 71, and both sides thereof to avoid contact with the field edge receiving attachment portion 61. A field edge receiving piece 721 which is directly faced to the side surface of the field edge receiver 3 and fixed by screws, and an upper surface piece which is bent in an L shape at the upper end and is engaged with the upper surface of the field edge receiver 3 722 and a lower surface piece 723 that is bent in an L shape at the lower end and engages the lower surface of the field receiver 3 in a support receiving shape, and is integrally formed in a U shape in side view. The upper surface piece 722 is formed with a width (may be longer) that is shorter than the upper surface width (thickness width) of the field receiver 3, and the lower surface piece 723 has its tip side on the lower surface of the field receiver 3. It is extended and formed with a length that passes through the zone. Also, a screw hole 72a is formed near the field edge 5 at the approximate center of the field edge receiving fixing piece 721.
野縁嵌挿固定部７３は、その先端側が延出形成された下面片７２３から、野縁５の側面に面接されるようにＬ字状に折曲形成されており、基端側が野縁受け３の側面よりも外方、つまり、野縁受け３の下面幅（厚さ幅）よりも外方に延出形成されている。野縁嵌挿固定部７３の先端側と基端側端部の延出部位に、それぞれ野縁受け３の下面域（厚さ幅）よりも外方に位置する２個所にネジ孔７３ａ、７３ｂが穿設されている。そして、野縁嵌挿固定部７３、７３は、野縁５の両側面にオーバーラップ（重合）された状態で嵌挿固定され、野縁受け３に組付けられた野縁５の側面周辺域を補強できるようになっている。また、特に、先端側ネジ孔７３ａの穿設位置は、野縁受け３と野縁５とが振動負荷による離間応力を受け易い側であることから、野縁受け固定片７２１のネジ孔７２ａから充分に離間した、野縁受け３の厚さ幅の２倍強の長さ位置となっており、それぞれをネジ固定した際に離間方向への応力を確りと受け止めて、両者を一体化された状態で密着傾動が行なわれるよう組付け固定され、離間や開きを規制して耐震剛性強度を高めることが可能な配置構成となっている。 The field edge fitting and fixing portion 73 is bent in an L shape so as to be in contact with the side surface of the field edge 5 from the lower surface piece 723 having its distal end extended and formed. 3 is formed to extend outward from the side surface of 3, that is, outward from the lower surface width (thickness width) of the field edge receiver 3. Screw holes 73a and 73b are provided at two positions located outside the lower surface area (thickness width) of the field edge receiver 3 at the extended portions of the distal end side and the proximal end side end part of the field edge insertion fixing part 73, respectively. Is drilled. Further, the field edge insertion and fixing portions 73 and 73 are inserted and fixed in a state of being overlapped (polymerized) on both side surfaces of the field edge 5, and the side edge peripheral area of the field edge 5 assembled to the field edge receiver 3. Can be reinforced. In particular, the drilling position of the tip side screw hole 73a is on the side where the field edge receiver 3 and the field edge 5 are susceptible to separation stress due to a vibration load, and therefore, from the screw hole 72a of the field edge receiving fixing piece 721. It is a well-spaced position that is more than twice the thickness width of the field edge receiver 3, and when the screws are fixed to each other, the stress in the separation direction is reliably received, and both are integrated. It is assembled and fixed so that the close-contact tilting is performed in the state, and the seismic rigidity strength can be increased by regulating separation and opening.
さて、上記のように構成した耐震補強金具７を用いて、野縁取付金具６により組付けられた野縁受け３と野縁５の組付け構造を補強する取り付け手順について、図５、図６を参照して詳細に説明する。図５は野縁受け３と野縁５に取り付けした状態を示す正面図、図６の（Ａ）は耐震補強金具７を野縁受け３の側面側に配設した一部破断側面図、（Ｂ）は野縁受け３の開口側に配設した側面図である。これら図に示すように、本発明の実施態様に係る耐震補強金具７を取り付けするには、新設、既設を問わず、野縁受け３と野縁５とが野縁取付金具６を介して組付けられた天井下地において、先ず、耐震補強金具７（野縁受け被覆部７１）を傾斜状態で、野縁受け取付け部６１の部位となる野縁受け３の側方、即ち、野縁受け３の側面側または開口側に配置させ、上面片７２２、７２２の先端を野縁受け３の上面に当接セットさせる。 Now, with respect to the mounting procedure for reinforcing the assembled structure of the field edge receiver 3 and the field edge 5 assembled by the field edge mounting bracket 6 using the seismic reinforcement bracket 7 configured as described above, FIGS. Will be described in detail with reference to FIG. FIG. 5 is a front view showing a state in which the field edge receiver 3 and the field edge 5 are attached, and FIG. 6A is a partially broken side view in which the seismic reinforcement bracket 7 is disposed on the side surface side of the field edge receiver 3. B) is a side view arranged on the opening side of the field receiver 3. As shown in these drawings, in order to attach the seismic reinforcement bracket 7 according to the embodiment of the present invention, the field edge receiver 3 and the field edge 5 are assembled via the field edge attachment metal 6 regardless of whether they are newly installed or existing. In the attached ceiling base, first, the seismic reinforcement bracket 7 (the edge receiving cover portion 71) is inclined, and the side of the field receiving edge 3 serving as the portion of the field edge receiving mounting portion 61, ie, the field edge receiving 3 The top surfaces of the upper surface pieces 722 and 722 are set in contact with the upper surface of the field edge receiver 3.
この傾斜セット状態から、野縁嵌挿固定部７３、７３を野縁５の両側面に挿入させ、回転させながら、野縁受け固定片７２１、７２１を野縁受け３の側面側（または開口側）に、下面片７２３、７２３を野縁受け３の下面にスライド当接させれば、野縁嵌挿固定部７３、７３もスライド嵌挿されてセット状態とすることができる。次いで、ドリルタッピングビス等のネジ９を用いて、野縁受け固定片７２１をネジ孔７２ａを介して野縁受け３の側面にそれぞれネジ固定した後、野縁嵌挿固定部７３をネジ孔７３ａ、７３ｂの２個所で、野縁５の両側面にそれぞれネジ固定すれば取付け作業が完了する。
なお、耐震補強金具７を野縁受け３の開口側に取り付けする場合には、通しネジ９ａ（ドリルビスや締結ボルト）を用い、野縁受け３の側面に挿通してネジ固定すれば良く、この側面へのネジ固定と野縁支持受け部６３との共同作用により、野縁受け３の下面と逆Ｕ字状溝５ａとの振動による離間をより強固に規制することができる。
From this inclined set state, the field edge receiving and fixing portions 73 and 73 are inserted into both side surfaces of the field edge 5 and rotated, while the field edge receiver fixing pieces 721 and 721 are moved to the side surface side (or the opening side) of the field edge receiver 3. If the lower surface pieces 723, 723 are slidably brought into contact with the lower surface of the field edge receiver 3, the field edge insertion fixing parts 73, 73 are also slid into the set state. Next, using a screw 9 such as a drill tapping screw, the field edge receiving fixing piece 721 is fixed to the side surface of the field edge receiving member 3 via the screw hole 72a, and then the field edge fitting insertion fixing part 73 is connected to the screw hole 73a. , 73b, the mounting operation is completed if screws are fixed to both sides of the field edge 5, respectively.
In addition, when attaching the seismic reinforcement metal fitting 7 to the opening side of the field edge receiver 3, it is sufficient to use a through screw 9a (drill screw or fastening bolt) and insert it into the side surface of the field edge receiver 3 to fix the screw. By the joint action of the screw fixing to the side surface and the field edge support receiving portion 63, the separation between the lower surface of the field edge receiver 3 and the inverted U-shaped groove 5a can be more firmly regulated.
この様にネジ固定して取り付けすると、野縁受け３と野縁５とが、野縁取付金具６自体やその支持受け構造に依存することなく、野縁受け３の下面と逆Ｕ字状溝５ａの上面とが密着した状態で、それぞれが野縁受け嵌装固定部７２と野縁嵌挿固定部７３とによって、独立一体化された新たな組付け構造をもって組付けすることができる。殊に、ネジ孔７２ａのネジ固定部位の野縁受け固定片７２１を中心に、ハ字状に末広がりして野縁受け３の下面幅（厚さ幅）よりも外方に位置する２個所のネジ孔７３ａと７３ｂのネジ固定部位が三角形状に３点配置され、振動負荷応力を分散して、組付け剛性強度が向上された耐震構造を得ることができ、野縁受け３の下面が下面片７２３に密着支持受けされた状態で、かつ、Ｌ字状に折曲形成された野縁嵌挿固定部７３が、野縁受け３の下面域周辺となる野縁５の開口側とその側面域全体が耐震補強された状態で、両者間に互いに圧接するような振動負荷が直接的に加わることが規制され、野縁５自体の剛性強度が高められ、直交する交差角度ズレすることなく密着状態と直角度が維持され、三者が密着一体化された状態で揺れの共同化が図られ、ねじれや傾動を受け止めて、これらが有機的に一体となった共同剛性力によって、野縁受け３と野縁５との間の離間やガタツキ、位置ズレ等を防止るとができる。
When fixed with screws in this manner, the field edge receiver 3 and the field edge 5 are not dependent on the field edge mounting bracket 6 itself or its support receiving structure, and the lower surface of the field edge receiver 3 and the inverted U-shaped groove. In a state where the upper surface of 5a is in close contact with each other, each can be assembled with a new assembling structure that is independently integrated by the field edge receiving and fixing part 72 and the field edge insertion and fixing part 73. In particular, there are two locations that are spread out in a C shape and located outside the lower surface width (thickness width) of the field edge receiver 3 around the field edge receiving piece 721 at the screw fixing portion of the screw hole 72a. The screw fixing portions of the screw holes 73a and 73b are arranged at three points in a triangular shape, and the vibration load stress can be dispersed to obtain an earthquake resistant structure with improved assembly rigidity strength. The side edge fitting insertion and fixing portion 73 bent and formed in an L shape in a state of being closely supported and received by the piece 723 has an opening side and a side surface of the field edge 5 around the lower surface area of the field edge receiver 3. In a state where the entire area is reinforced with earthquake resistance, it is restricted that vibration loads that are pressed against each other are directly applied to each other, the rigidity strength of the field edge 5 itself is increased, and the crossing angle does not shift at right angles. The state and perpendicularity are maintained, and the shaking is shared while the three parties are closely integrated. Achieved is by receiving a twisting and tilting, by joint rigidity they become organically integrated, spaced and rattling between the field edge receiving 3 and ceiling joists 5, it is collected by Ru prevent positional deviation or the like.
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、既設や新設施工が行われた躯体天井部１に対して、野縁取付金具６により組付けられた野縁受け３と野縁５の組付け構造を、耐震補強金具７によって耐震補強するのであるが、本発明にかかる耐震補強金具７は、野縁受け取付け部６１に対向被覆するよう形成された野縁受け被覆部７１と、該野縁受け被覆部７１の両側に延出されて野縁受け３に側方から外嵌される側面視コ字状に形成された一対の野縁受け嵌装固定部７２、７２と、この野縁受け嵌装固定部７２の下面片にＬ字状に折曲形成されて、野縁５の両側面にそれぞれ面接嵌挿される一対の野縁嵌挿固定部７３、７３とを一体的に備えると共に、野縁嵌挿固定部７３を、野縁受け嵌装固定部７２を野縁受け３に外嵌させた際に、その先端側が野縁受け３の下面域を通過する長さ幅をもって延出形成せしめ、野縁受け嵌装固定部７２と野縁嵌挿固定部７３は、それぞれ野縁受け３に外嵌させ、野縁５に嵌挿させた状態で、野縁受け嵌装固定部７２を野縁受け３の側面にネジ固定し、かつ、野縁嵌挿固定部７３を、その基端側部位と野縁受け３の下面域よりも外方に位置する先端側部位の２個所で、野縁５の側面にネジ固定するよう構成されている。 In the embodiment of the present invention configured as described above, the field edge receiver 3 and the field edge 5 assembled by the field edge mounting bracket 6 with respect to the frame ceiling part 1 which has now been installed or newly constructed. The seismic reinforcement metal fitting 7 according to the present invention includes a field edge receiving covering portion 71 formed to cover the field edge receiving attachment portion 61, and a seismic reinforcing metal fitting 7 according to the present invention. A pair of field edge receiving fitting fixing portions 72, 72 extending in both sides of the field edge receiving covering 71 and externally fitted to the field edge receiver 3 from the side, A pair of field edge fitting and fixing portions 73 and 73 that are bent and formed in an L-shape on the lower surface piece of the field edge receiving and fixing portion 72 and are surface-inserted into both side surfaces of the field edge 5 are integrally formed. In addition, the field edge fitting insertion fixing part 73 and the field edge receiving insertion fixing part 72 are externally fitted to the field edge receiver 3. Further, the tip end side is extended and formed with a length and width passing through the lower surface area of the field edge receiver 3, and the field edge receiving and fixing part 72 and the field edge inserting and fixing part 73 are respectively fitted to the field edge receiver 3. Then, in the state of being inserted into the field edge 5, the field edge receiving and fixing part 72 is screwed to the side surface of the field edge receiver 3, and the field edge inserting and fixing part 73 is It is configured to be screwed to the side surface of the field edge 5 at two positions on the tip side portion located outside the lower surface area of the field edge receiver 3.
この様に構成すると、野縁５を、その逆Ｕ字状溝５ａ内に挿入される野縁支持受け部６３によって支持受けすることで、野縁取付金具６を介して野縁受け３に組付けされた構造を補強するものでありながら、当該野縁支持受け部６３による野縁の支持受け構造を利用し、かつ、当該野縁取付金具６自体やその支持受け構造に依存することなく、野縁受け嵌装固定部７２を野縁取付金具６の両側面で、野縁嵌挿固定部７３を野縁受け３の厚さ幅よりも外方位置となる２個所で、交差配設された野縁受け３と野縁５に対して、それぞれ直接ネジ固定による独立一体化した組付けが行えるだけでなく、野縁受け嵌装固定部７２の下面片７２３が野縁受け３の下面域を確りと密着させて受け止め支持した状態でネジ固定され、Ｌ字状に折曲された野縁嵌挿固定部７３の先端側が、当該下面域を通過する長さ幅をもって野縁５の側面にオーバーラップした状態で、野縁受け３のネジ固定部（ネジ孔７２ａ）を中心に、野縁５の２個所のネジ固定部（ネジ孔７３ａと７３ｂ）を結ぶ三角形状のハ字状に末広がりする３点部位で確りとネジ固定され、振動負荷応力を分散して、離間や圧接応力を受け易い側を強固に密着させた状態で、野縁受け３と野縁５との組付け剛性強度を高めることができ、しかも、当該下面域周辺となる野縁５の開口側（逆Ｕ字状溝５ａ）とその側面域全体を耐震補強することができる。 With this configuration, the field edge 5 is supported and received by the field edge support receiving portion 63 inserted into the inverted U-shaped groove 5 a, so that the field edge 5 is assembled to the field edge receiver 3 via the field edge mounting bracket 6. While reinforcing the attached structure, using the field edge support receiving structure by the field edge support receiving portion 63, and without depending on the field edge mounting bracket 6 itself or its support receiving structure, The field edge receiving / fixing portions 72 are arranged on both sides of the field edge mounting bracket 6, and the field edge insertion / fixing portions 73 are arranged at two positions outside the thickness width of the field edge receiver 3. In addition, the lower edge piece 723 of the field edge receiving and fixing portion 72 can be attached to the field edge receiver 3 and the field edge 5 by direct screw fixing. The field edge is fixed with screws in a state where it is firmly attached and received and supported, and bent into an L shape. In a state where the distal end side of the insertion and fixing portion 73 overlaps the side surface of the field edge 5 with a length and width passing through the lower surface area, the field edge 5 is centered on the screw fixing portion (screw hole 72a) of the field edge receiver 3. The two screw fixing parts (screw holes 73a and 73b) are securely fixed at three points that spread out in a triangular C shape, disperse the vibration load stress, and are susceptible to separation and pressure contact stress. Assembling rigidity strength between the field edge receiver 3 and the field edge 5 can be increased in a state where the sides are firmly adhered to each other, and the opening side of the field edge 5 around the lower surface area (inverted U-shaped groove) 5a) and the entire side area can be seismically reinforced.
その結果、シングル固定タイプや挟込み固定タイプ、指圧変形が可能・不能などのタイプの如何にかかわらず、種々の野縁取付金具６が用いられた既設、新設の天井下地に採用することができると共に、地震等の揺れにより、前後左右等に傾動する振動負荷を受けた際に、三者が密着一体化された状態でねじれや傾動を受け止めて、これらが有機的に一体となった共同剛性力によって、野縁受け３等他の部材よりも薄板にて形成される野縁５自体のねじれや変形を防止して、逆Ｕ字状溝に集中した野縁受け３への上動圧接や離間するような振動負荷を、野縁嵌挿固定部７３で確りと受け止めて分散することができ、野縁取付金具６への負荷影響が減少または回避され、両者間の密着状態を強固に維持し、直交する交差角度ズレを規制して直角度を維持することができ、野縁受け３と野縁５との間のガタツキや位置ズレを防止して、天井下地全体の耐震性を向上させることができる。 As a result, it can be used for existing and new ceiling bases that use various field edge mounting brackets 6 regardless of whether they are a single fixed type, a pinched fixed type, or a type in which finger pressure deformation is possible or impossible. At the same time, when subjected to a vibration load that tilts forward, backward, left, right, etc. due to shaking such as an earthquake, the joint rigidity of these three is organically integrated by receiving twisting and tilting in a state where they are closely integrated Due to the force, it is possible to prevent twisting and deformation of the field edge 5 itself which is formed of a thin plate than other members such as the field edge receiver 3, and the upper dynamic pressure contact with the field edge receiver 3 concentrated in the inverted U-shaped groove Vibration loads that are separated can be reliably received and distributed by the field edge fitting and fixing portion 73, and the influence of the load on the field edge mounting bracket 6 is reduced or avoided, and the close contact state between both is firmly maintained. Right angle by regulating the crossing angle deviation perpendicular to each other Can be maintained, to prevent rattling or displacement between the field edge receiving 3 and ceiling joists 5, it is possible to improve the vibration resistance of the entire ceiling foundation.
また、野縁受け嵌装固定部７２の下面片７２３の先端側は、野縁受け３の下面域を通過する長さ幅をもって延出され、野縁嵌挿固定部７３は、当該下面片７２３に折曲形成されてされているので、下面片７２３と野縁嵌挿固定部７３がＬ字状に折曲形成された補強構造となって、野縁受け３の下面が下面片７２３に密着支持受けされ、かつ、野縁嵌挿固定部７３が、野縁受け３の下面域周辺となる野縁５の開口側とその側面域全体が耐震補強され、これらが有機的に三位一体となった密着組付け状態による共同剛性力をもって、ねじれや傾動が一体化された状態で振動負荷を受け止めて、野縁受け３と野縁５との間に互いに圧接するような振動負荷が直接的に加わることが規制されると共に、直交する交差角度ズレを規制して、両者間の離間やガタツキ、位置ズレ等を防止し、直角度の恒久的な維持を図ることができる。 Further, the front end side of the lower surface piece 723 of the field edge receiving fitting fixing portion 72 is extended with a length width passing through the lower surface area of the field edge receiving member 3, and the field edge fitting insertion fixing portion 73 is connected to the lower surface piece 723. Since the lower surface piece 723 and the field edge fitting insertion fixing part 73 are bent in an L shape, the lower surface of the field edge receiver 3 is in close contact with the lower surface piece 723. The field edge fitting insertion fixing part 73 is supported and received, and the opening side of the field edge 5 and the entire side surface area around the lower surface area of the field edge receiver 3 are seismically reinforced, and these are organically trinically integrated. With the joint rigidity force due to the tightly assembled state, the vibration load is received in a state where the torsion and the tilt are integrated, and the vibration load is pressed directly between the field edge receiver 3 and the field edge 5. Is controlled, and the crossing angle deviation perpendicular to the Backlash to prevent misalignment and the like, it is possible to achieve a permanent maintenance of perpendicularity.
また、野縁嵌挿固定部７３は、その基端側が野縁受け３の側面よりも外方に延出形成され、該基端側の延出部位と先端側の延出部位とを、それぞれ野縁受け３の下面域よりも外方に位置するネジ孔７３ａと７３ｂの２個所で、野縁５の側面にネジ固定されているので、ネジ孔７２ａのネジ固定部位の野縁受け固定片７２１を中心に、ハ字状に末広がりして野縁受け３の下面幅（厚さ幅）よりも外方に位置する２個所のネジ孔７３ａと７３ｂのネジ固定部位が三角形状に３点配置され、振動負荷応力を分散して、組付け剛性強度が向上された耐震構造を得ることができる。 In addition, the base edge side of the field edge fitting and fixing portion 73 is formed to extend outward from the side surface of the field edge receiver 3, and the base part side extension part and the tip side extension part are respectively formed. Since the screw holes 73a and 73b are located outside the lower surface area of the field edge receiver 3 and are fixed to the side surface of the field edge 5, the field edge receiver fixing piece of the screw fixing part of the screw hole 72a is secured. Three screw holes 73a and 73b are arranged in a triangular shape at three points centered at 721 and spread outwardly in the shape of a letter C and located outside the lower surface width (thickness width) of the field edge receiver 3 In addition, the vibration load stress can be dispersed to obtain an earthquake resistant structure with improved assembly rigidity.
また、野縁受け被覆部７１は、野縁受け取付け部６１と離間して非接触状態で対向被覆するよう平面視略凹状に形成されているので、野縁受け被覆部７１の野縁受け３の側面と離間する凹状幅は、種々の野縁取付金具６の形状の違いによって、野縁受け３に取着された野縁受け取付け部６１の膨出幅が異なっていても、野縁受け嵌装固定部７２を野縁受け３の側面に面当て被嵌した際に、非接触状態で被覆することができるだけでなく、野縁受け嵌装固定部７２、７２を野縁受け３に精度良く密着固定することができ、野縁取付金具６自体やその支持受け構造に依存しない新たな組付け構成をもって、野縁受け３と野縁５とを耐震補強することができる。
Further, the field edge receiving cover portion 71 is formed in a substantially concave shape in a plan view so as to be separated from the field edge receiving mounting portion 61 and to cover the field edge receiving attachment portion 61 in a non-contact state. The concave width that is spaced apart from the side surface of the rim is not limited even if the bulge width of the ridge receiving portion 61 attached to the ridge receiving 3 is different due to the difference in the shape of the various rim mounting brackets 6. When the fitting fixing part 72 is fitted to the side surface of the field edge receiver 3, not only can it be covered in a non-contact state, but also the field edge receiver fixing parts 72, 72 can be accurately applied to the field edge receiver 3. It can be fixed firmly and can be seismically reinforced with the field edge receiver 3 and the field edge 5 with a new assembly structure that does not depend on the field edge mounting bracket 6 itself or its support receiving structure.
