図２及び３に示すように、受け部材４の下部側に設けた係止凹部２２は、左右対称の茸状或いはＴ字状に切欠かれた形状である。このため、係止凹部２２は、中心線（Ｐ）に対して左右対称の形状である。係止凹部２２には、具体的には、受け部材４の下端部から上方に切り欠かれた入口部３２、及び入口部３２の上部に形成され入口部３２よりも横幅の広い係止部３４が設けられている。係止部３４の下部側には、入口部３２の上部から左右に広がる形状の係止当部３６が形成されている。 As shown in FIGS. 2 and 3, the engagement recess 22 provided on the lower side of the receiving member 4 has a symmetrical mushroom shape or T-shaped notch shape. Therefore, the locking recess 22 has a symmetrical shape with respect to the center line (P). More specifically, the locking recess 22 includes an entrance portion 32 notched upward from the lower end of the receiving member 4 and a locking portion 34 formed above the entrance portion 32 and having a wider width than the entrance portion 32 . is provided. A locking contact portion 36 is formed on the lower side of the locking portion 34 so as to extend from the upper portion of the entrance portion 32 to the left and right.

また、受け部材４の左右の端部は、それぞれ係止凹部２２の中心線（Ｐ）に沿って切断した片半の係止凹部２３の形状に形成されている。つまり、各端部は、左右対称形状の係止凹部２２の中心線（Ｐ）の片側（片半分）の形状である。
このため、受け部材４の端部を他の受け部材４の端部と突き合せた場合（左の片半の係止凹部２３と右の片半の係止凹部２３とを一体化）には、この部位に一つの係止凹部２２が形成される。このため、隣り合う受け部材４同士は、どの箇所を見ても係止凹部２２が等間隔に形成される形態となる。そして、受け部材４は、必要により複数個を横に並べて接続（延設）して使用することができる。 Further, the left and right ends of the receiving member 4 are formed in the shape of half locking recesses 23 cut along the center line (P) of the locking recesses 22 . That is, each end has a shape of one side (one half) of the center line (P) of the symmetrical locking recess 22 .
Therefore, when the end portion of the receiving member 4 is butted against the end portion of the other receiving member 4 (the locking concave portion 23 of the left half and the locking concave portion 23 of the right half are integrated), , one locking recess 22 is formed at this portion. For this reason, the receiving members 4 adjacent to each other have a form in which the engaging recesses 22 are formed at regular intervals wherever viewed. If necessary, a plurality of receiving members 4 can be arranged side by side and connected (extended) for use.

また、受け部材４の縦板部１８の両端部の中央部近傍には、それぞれ位置を決めるために切り欠いた位置決め部３０が形成されている。受け部材４同士を並べて延設する場合、両受け部材４同士の上下位置が正確に合っているか否かを、位置決め部３０同士が合っていることで確認することができる。 Positioning portions 30 are formed near the central portions of both ends of the vertical plate portion 18 of the receiving member 4 so as to determine the respective positions. When the receiving members 4 are extended side by side, whether or not the vertical positions of both receiving members 4 are correctly aligned can be confirmed by checking that the positioning portions 30 are aligned with each other.

前記横材６としては、天井面材を取り付ける野縁材、或いは野縁材を受ける野縁受け材等が該当する。野縁受け材を横材とした場合には、この野縁受け材の下部に野縁材を接続して用いる。ここでは、横材６として野縁材６を用いる。
野縁材６は、上部が開口された断面Ｕ字状の長尺材である。野縁材６は、鋼板等の金属板材、或いはアルミニウム等の軽量金属が用いられる。野縁材６は、底板部４２、この左右部から立ち上る側板部４４，４４、及び各側板部の上部から、内側に逆Ｕ字状に屈曲形成された縁部４６，４６からなる。 The horizontal member 6 corresponds to a joist member for attaching a ceiling surface member, a joist receiving member for receiving a joist member, or the like. When the joist receiving member is a horizontal member, the joist member is connected to the lower part of the joist receiving member. Here, a hoisting member 6 is used as the horizontal member 6 .
The hoisting material 6 is an elongated material having a U-shaped cross section with an upper opening. A metal plate material such as a steel plate or a lightweight metal such as aluminum is used for the joist material 6 . The hoisting material 6 is composed of a bottom plate portion 42, side plate portions 44, 44 rising from the left and right portions, and edge portions 46, 46 bent inward in an inverted U shape from upper portions of the side plate portions.

図４は、受け部材４の係止凹部２２に係止された野縁材６を示したものである。
ここで、隣り合う係止凹部２２間の中心線同士の間隔（Ｌ）は、野縁材６の側板部４４，４４同士の間隔（Ｍ）と同一（Ｌ＝Ｍ）にしている。また、受け部材４の隣り合う係止凹部２２に野縁材６の左右の縁部４６，４６をそれぞれ係止させた状態では、野縁材６の縁部４６，４６は、係止凹部２２（係止部３４）の内側（他の縁部４６側）に当接する状態となることが好ましい。 FIG. 4 shows the hoisting member 6 locked in the locking recess 22 of the receiving member 4. As shown in FIG.
Here, the interval (L) between the centerlines of the adjacent engaging recesses 22 is the same as the interval (M) between the side plate portions 44, 44 of the joist member 6 (L=M). Further, when the left and right edges 46, 46 of the joist material 6 are respectively engaged with the adjacent engaging recesses 22 of the receiving member 4, the edges 46, 46 of the joist material 6 It is preferable to be in a state of abutting on the inner side (the other edge portion 46 side) of the (locking portion 34).

詳しくは、受け部材４に野縁材６を係止させる際、係止凹部２２の入口部３２から係止部３４に突入した野縁材６の縁部４６は、その端部（下方向き）が係止凹部２２の係止当部３６に当たって係止される。この場合、野縁材６の側板部４４，４４は、少し外向きに開いた状態で、係止凹部２２の係止部３４に突入し、突入後は側板部４４，４４のバネ力で内向きに閉じる方向に作用し、野縁材６の縁部４６が係止部３４の側部に当たる状態となり、前記係止当部３６への係止が行われる。 Specifically, when the hoisting material 6 is locked to the receiving member 4, the edge 46 of the hoisting material 6 that protrudes from the entrance 32 of the locking recess 22 into the locking part 34 is the end (downward) abuts against the locking contact portion 36 of the locking recess 22 and is locked. In this case, the side plate portions 44, 44 of the hoisting material 6 enter the locking portion 34 of the locking recess 22 in a slightly outwardly opened state, and after the insertion, the spring force of the side plate portions 44, 44 inwards. The edge 46 of the hoisting member 6 hits the side of the locking portion 34, and the locking to the locking portion 36 is performed.

このため、野縁材６の縁部４６は、下方向の力が作用しても、その先端部が係止凹部２２の係止当部３６に当接し、この係止状態が維持され野縁材６が外れることはない。
ここでは、受け部材４に形成された各係止凹部２２同士の間隔（Ｌ）は全て一定としている。このため、受け部材４の下部に野縁材６を配置する場合、何れの係止凹部２２（及び隣り合う係止凹部２２）であっても自由に選択可能であり、所望する係止凹部２２に取り付けることができる。 For this reason, even if a downward force is applied to the edge 46 of the joist material 6, the tip of the joist 6 abuts the locking abutment 36 of the locking recess 22, and this locked state is maintained. The material 6 never comes off.
Here, the intervals (L) between the locking recesses 22 formed in the receiving member 4 are all constant. For this reason, when arranging the hoisting member 6 in the lower part of the receiving member 4, any of the locking recesses 22 (and the adjacent locking recesses 22) can be freely selected, and the desired locking recesses 22 can be attached to

また、特定の隣り合う係止凹部２２同士の間隔（Ｌ）を、野縁材６の側板部同士の間隔（Ｍ）と同じ（Ｌ＝Ｍ）とし、他の隣り合う係止凹部２２同士の間隔（Ｌ）を自由に設定するようにしてもよい。但し、この場合、前記特定の隣り合う係止凹部２２同士の間にのみ野縁材６の配置が可能となる。また、前記特定の隣り合う係止凹部２２同士は、所定の間隔（一定の間隔）をおいて複数個所設けることとしてもよい。 In addition, the interval (L) between specific adjacent locking recesses 22 is the same as the interval (M) between the side plate portions of the hoisting material 6 (L=M), and the other adjacent locking recesses 22 You may make it set the space|interval (L) freely. However, in this case, the hoisting material 6 can be arranged only between the specific adjacent locking recesses 22 . Further, the specific adjacent locking recesses 22 may be provided at a plurality of locations at predetermined intervals (constant intervals).

図５に示すように、前記クリップ部材８は、背面部５０と左右の側部５２，５２を有する断面コの字状の形状である。クリップ部材８は、板状の鋼材等を屈曲加工して得たものである。各側部５２，５２の下部側には、背面部５０との間が切欠かれた側片部５４，５４が形成されている。 As shown in FIG. 5, the clip member 8 has a U-shaped cross-section having a back portion 50 and left and right side portions 52 , 52 . The clip member 8 is obtained by bending a plate-shaped steel material or the like. Side piece portions 54 , 54 are formed on the lower side of each of the side portions 52 , 52 with a notch between them and the back portion 50 .

前記背面部５０は、左右部位の下部側がそれぞれ切欠かれた凹部５６，５６が形成され、また中央部の下部寄りの位置にバーリング加工等によるネジ孔部５８が形成されている。このネジ孔部５８には、内周部にネジ溝が刻設されている。
また、前記各側部５２の背面部５０側は、それぞれ前記凹部５６が少し食い込んだ状態で切り欠かれている。そして、各側部５２の下部側の側片部５４の中央部にはそれぞれ孔部５５が設けられ、また下部の左右の角部はそれぞれ面取り部５７が形成された形状である。 The rear portion 50 has recesses 56, 56 formed by notching the lower portions of the left and right portions, respectively, and a screw hole portion 58 formed by burring processing or the like at a position near the lower portion of the central portion. A thread groove is formed on the inner periphery of the screw hole portion 58 .
In addition, each side portion 52 on the side of the back portion 50 is notched in such a manner that the concave portion 56 slightly bites into each portion. A hole portion 55 is provided in the central portion of the side piece portion 54 on the lower side of each side portion 52, and chamfered portions 57 are formed at the left and right corner portions of the lower portion.

次に、前記天井構造およびその施工方法について説明する。
建物の構造躯体に係る構造材２として、母屋材２はそれぞれ屋根裏に沿う状態で横向き（水平）に配置される。また、各母屋材２同士は、通常屋根裏の傾斜面の上部から下部にかけて階段状（高低差）に配置され、屋根の傾斜により各母屋材２同士は高さが異なる。 Next, the ceiling structure and its construction method will be described.
As the structural members 2 related to the structural frame of the building, the purlin members 2 are arranged sideways (horizontally) along the attic. Further, the purlin materials 2 are usually arranged in a stepped manner (height difference) from the upper part to the lower part of the sloped surface of the attic, and the heights of the purlin materials 2 differ according to the inclination of the roof.

このため、受け部材４は母屋材２に沿って取り付けられるが、受け部材４の下部にこれと交差（直交）する向きに取り付けられる野縁材６は、屋根の傾斜角度と同様な角度で傾斜した状態で配置される。また、野縁材６の下部（底板部４２）に取り付けられる天井面材１０は、自然と野縁材６の傾斜角度、つまり屋根の傾斜角度と同様な傾斜角度（傾斜面）で敷設される。 For this reason, the receiving member 4 is attached along the purlin material 2, but the hoisting material 6 attached to the lower part of the receiving member 4 in a direction crossing (perpendicular to) this is inclined at an angle similar to the inclination angle of the roof. It is placed in a state where In addition, the ceiling surface material 10 attached to the lower part (bottom plate part 42) of the joist material 6 is naturally laid at an inclination angle (inclined surface) similar to the inclination angle of the joist material 6, that is, the inclination angle of the roof. .

なお、建物の構造材２として、梁材等の架設の高さが一定（水平位置）のものを用いる場合には、受け部材４及び野縁材６等は何れも水平に配置され、天井面材１０についても水平な状態で敷設される。また、構造材２として、例えば建物の屋根が比較的平坦な（屋上形式）屋根裏の母屋材２については、何れの母屋材２も高さが一定に架設されるため、この場合も同様に水平な状態で敷設される。 In addition, when beams or the like having a constant erection height (horizontal position) are used as the structural members 2 of the building, the receiving members 4 and the joist members 6 and the like are all arranged horizontally, and the ceiling surface The material 10 is also laid horizontally. In addition, as the structural material 2, for example, the purlin material 2 of the attic where the roof of the building is relatively flat (rooftop type), since any purlin material 2 is erected at a constant height, in this case also the horizontal installed in good condition.

前記母屋材２を利用して受け部材４が取り付けられるが、この場合、母屋材２の側面部１４の下寄りの箇所に受け部材４を取り付ける。ここでは、母屋材２の側面部１４は縦（垂直）向きの平坦な面であり、受け部材４の縦板部１８は下向きに配置される。
他に、母屋材２の側面部１４が斜め下方に傾斜した形態であっても、同様に側面部１４の下寄りの箇所に受け部材４を取り付けることができる。この場合、受け部材４は斜め下向きに傾斜した状態で配置される。 The receiving member 4 is attached using the purlin material 2 . In this case, the receiving member 4 is attached to the lower part of the side surface portion 14 of the purlin material 2 . Here, the side surface portion 14 of the purlin 2 is a vertically (vertically) flat surface, and the vertical plate portion 18 of the receiving member 4 is arranged downward.
Alternatively, even if the side surface portion 14 of the purlin material 2 is inclined downward, the receiving member 4 can be attached to the lower portion of the side surface portion 14 in the same manner. In this case, the receiving member 4 is arranged in a state of being inclined obliquely downward.

受け部材４を構造材２の側面部１４に取り付ける際、その配置の上下位置により天井面材１０の敷設位置が決定される。この場合、受け部材４に設けた上下に長い長孔２８を利用する。受け部材４を構造材２に取り付けるとき、この受け部材４の上下位置を決める際、当該長孔２８に止着具としてのネジ６０で仮止め（仮固定）する。なお、ネジ６０としては、セルフドリリングネジ等が用いられる。 When the receiving member 4 is attached to the side surface portion 14 of the structural member 2, the laying position of the ceiling panel 10 is determined by the vertical position of the arrangement. In this case, a vertically elongated hole 28 provided in the receiving member 4 is used. When the receiving member 4 is attached to the structural member 2 and the vertical position of the receiving member 4 is determined, the elongated hole 28 is temporarily fastened (temporarily fixed) with a screw 60 as a fastener. A self-drilling screw or the like is used as the screw 60 .

長孔２８は、一つの受け部材４に６箇所設けられており、必要な箇所の長孔２８をネジ６０で仮止めし、受け部材４の全体の高さ位置が定められた高さに配置されているかを確認する。そして、ネジ６０のねじ込み具合により、受け部材４を長孔２８の範囲で上下に移動させ、受け部材４の高さ位置を調整する。受け部材４の高さが決まれば、長孔２８へのネジ６０をかたく締めておく。 Six long holes 28 are provided in one receiving member 4, and the long holes 28 at required positions are temporarily fixed with screws 60, and the overall height position of the receiving member 4 is arranged at a predetermined height. Check if it is The height position of the receiving member 4 is adjusted by moving the receiving member 4 up and down within the range of the elongated hole 28 depending on how the screw 60 is screwed. Once the height of the receiving member 4 is determined, the screw 60 to the long hole 28 is tightly tightened.

受け部材４は、構造材２の側面部１４の下寄りの位置に配置する。具体的には、構造材２の側面部１４の下端部に、受け部材４の上下の略中央部が配置される位置に取り付ける。
なお、前後の必要な箇所にそれぞれ受け部材４を配置し（仮固定）、これらの係止凹部２２間に野縁材６を仮係止させ、野縁材６の配置状態により受け部材４の高さ位置を確認するようにしても良い。
受け部材４の位置が決まれば、受け部材４の各固定孔２６にネジ６０を螺着し、受け部材４を母屋材２に固定（本固定）する。 The receiving member 4 is arranged at a lower position of the side surface portion 14 of the structural member 2 . Specifically, it is attached to the lower end portion of the side surface portion 14 of the structural member 2 at a position where the substantially central portion of the upper and lower portions of the receiving member 4 is arranged.
In addition, the receiving members 4 are arranged (temporarily fixed) at the necessary places in the front and rear, and the hoisting members 6 are temporarily locked between these locking recesses 22. Depending on the arrangement of the hoisting members 6, the receiving members 4 You may make it confirm a height position.
Once the position of the receiving member 4 is determined, screws 60 are screwed into the respective fixing holes 26 of the receiving member 4 to fix (permanently fix) the receiving member 4 to the purlin 2 .

また、受け部材４の長さは、例えば２０００～３０００ｍｍである。このため、母屋材２の長さによっては、複数の受け部材４を横に並べて配置する。そして、隣り合う受け部材４間は、各端部同士を突合して配置する。この際、各受け部材４の各端部に設けられた位置決め部３０を互いに合致させることで、両受け部材４の配置位置が正確に定まる。 Moreover, the length of the receiving member 4 is, for example, 2000 to 3000 mm. Therefore, depending on the length of the purlin material 2, a plurality of receiving members 4 are arranged side by side. Adjacent receiving members 4 are arranged so that their ends are abutted against each other. At this time, by aligning the positioning portions 30 provided at the ends of the receiving members 4 with each other, the arrangement positions of the receiving members 4 are accurately determined.

さらに、受け部材４の端部を他の受け部材４の端部と突き合せた場合、一方の受け部材４の片半の係止凹部２３と他方の受け部材４の片半の係止凹部２３同士が一体化し、この部位に一つの係止凹部２２が形成される。これにより、複数の受け部材４が形状的に一体化し、一個の受け部材４と同様の形態で配置することができる。
このように、隣り合う受け部材４同士は、どの箇所を見ても係止凹部２２が等間隔に形成される形態となる。そして、受け部材４は、必要により複数個を横に並べて接続（延設）して使用することができる。 Furthermore, when the end of the receiving member 4 is butted against the end of the other receiving member 4 , the engaging recess 23 on one half of the receiving member 4 and the engaging recess 23 on one half of the other receiving member 4 They are integrated with each other, and one locking recess 22 is formed at this site. As a result, the plurality of receiving members 4 can be integrated in shape and arranged in the same manner as one receiving member 4 .
In this way, the receiving members 4 adjacent to each other have a form in which the engaging recesses 22 are formed at equal intervals wherever viewed. If necessary, a plurality of receiving members 4 can be arranged side by side and connected (extended) for use.

受け部材４は母屋材２に沿って配置され、受け部材４の端部は、通常母屋材２の端部近傍に位置する。他の母屋材２についても、同様に受け部材４を配置する。各母屋材２同士は、屋根の傾斜により高さが異なり（階段状）、各受け部材４についても同様である。
このため、受け部材４と交差（直交）して取り付けられる野縁材６は、傾斜（屋根の傾斜角度と同様）した状態で配置される。また受け部材４は、互いに平行な状態で複数列並べて配置する。 The receiving member 4 is arranged along the purlin 2 , and the end of the receiving member 4 is generally positioned near the end of the purlin 2 . For other purlin materials 2, receiving members 4 are arranged in the same manner. The purlin members 2 have different heights (stepped) depending on the inclination of the roof, and the same applies to the receiving members 4 .
For this reason, the hoisting members 6 attached to intersect (perpendicularly) with the receiving members 4 are arranged in an inclined state (similar to the inclination angle of the roof). Further, the receiving members 4 are arranged in a plurality of rows parallel to each other.

受け部材４間に野縁材６を架け渡す際には、野縁材６を前後（傾斜方向）の各受け部材４の該当する係止凹部２２に取り付ける。この際、各受け部材４の端部は、係止凹部２２が全て同じ位置に配置されるようにしておく。これにより、受け部材４間に架け渡される野縁材６の取り付け場所等が簡単かつ正確に定められる。 When the hoisting materials 6 are bridged between the receiving members 4, the hoisting materials 6 are attached to the corresponding locking recesses 22 of the receiving members 4 in the front and rear (inclination directions). At this time, the end portions of the receiving members 4 are arranged such that all of the engaging recesses 22 are arranged at the same position. Thereby, the attachment place of the hoisting material 6 bridged between the receiving members 4, etc. are determined simply and correctly.

さて、前記配置された受け部材４の下部に、これと交差（直交）する方向に野縁材６を取り付ける。この野縁材６の取り付けに際しては、先ず野縁材６を受け部材４に仮止め（仮固定）し、さらにクリップ部材８を用いて両者を接合し固定（本固定）する。
なお、野縁材６は、屋根裏に階段状に配置された各母屋材２（高低差）に沿う状態となるため、屋根の傾斜角度と同程度の傾斜角を有して配置される。 Now, the hoisting material 6 is attached to the lower part of the receiving member 4 arranged as described above in a direction crossing (perpendicular to) this. When attaching the hoisting material 6, first, the hoisting material 6 is temporarily fixed (temporarily fixed) to the receiving member 4, and then both are joined and fixed (permanently fixed) using the clip member 8.
In addition, since the hoisting material 6 is in a state along each purlin material 2 (height difference) arranged in a stepped manner in the attic, it is arranged with an angle of inclination approximately the same as the angle of inclination of the roof.

また、受け部材４に取り付ける野縁材６の位置決めに際しては、受け部材４の下部に係止凹部２２が規則的に設けられていることから、野縁材６を取り付けるべき位置の係止凹部２２を記録（端部から何番目か等）しておけば、野縁材６の取り付け箇所（位置決め）が正確に定められる。また、隣り合う野縁材６同士の間隔についても、両野縁材６間の係止凹部２２の並び状態（個数等）を定めておけば、全体の野縁材６の配置位置が正確に決められる。 In addition, when positioning the ceiling joist material 6 attached to the receiving member 4, since the locking recesses 22 are regularly provided in the lower part of the receiving member 4, is recorded (such as the number from the end), the mounting location (positioning) of the hoisting material 6 can be determined accurately. In addition, regarding the interval between the adjacent joist materials 6, if the alignment state (number etc.) of the locking recesses 22 between both joist materials 6 is determined, the arrangement position of the entire joist material 6 can be accurately determined. be decided.

野縁材６は受け部材４の下部に配置し、取り付け箇所に該当する両（隣り合う）係止凹部２２，２２に係止させる。そして、野縁材６の両側板部４４，４４を、それぞれ両係止凹部２２，２２に差し込む。この場合、野縁材６の各側板部４４の上部に形成された各縁部４６を、それぞれ各係止凹部２２に係止させる。 The hoisting member 6 is arranged under the receiving member 4 and is locked to both (adjacent) locking recesses 22, 22 corresponding to the mounting location. Then, the both side plate portions 44, 44 of the hoisting material 6 are inserted into the both engaging recesses 22, 22, respectively. In this case, each edge 46 formed in the upper part of each side plate part 44 of the joist material 6 is each latched by each latching recessed part 22. As shown in FIG.

このとき、内側に屈曲形成された縁部４６は、係止凹部２２の係止当部３６に係止され、野縁材６は受け部材４に対して係止状態が維持されるため簡単には外れない。これにより、野縁材６は受け部材４に仮固定される。受け部材４と野縁材６が交差（直交）する箇所では、同様にして受け部材４に野縁材６を仮固定する。
なお、野縁材６は受け部材４の面に対して、直角より傾斜（屋根の傾斜）した状態で配置されるが、野縁材６の縁部４６と受け部材４の係止凹部２２との係止状態に何ら影響はない。 At this time, the edge portion 46 bent inwardly is engaged with the engaging portion 36 of the engaging recess 22, and the joist member 6 is maintained in the engaging state with respect to the receiving member 4, so that it can be easily removed. does not come off. Thereby, the hoisting member 6 is temporarily fixed to the receiving member 4 . At a location where the receiving member 4 and the hoisting material 6 intersect (perpendicularly), the hoisting material 6 is temporarily fixed to the receiving member 4 in the same manner.
In addition, the joist material 6 is arranged in a state inclined (roof inclination) from a right angle with respect to the surface of the receiving member 4, but the edge 46 of the joist material 6 and the locking recess 22 of the receiving member 4 has no effect on the locked state of

受け部材４に野縁材６を仮固定した後、クリップ部材８を用いて野縁材６を受け部材４に固定（本固定）する。クリップ部材８は、受け部材４の下寄りの部位に取り付ける。これによりクリップ部材８は、構造材２の側面部１４の下端部より下方に配置される。また、野縁材６は構造材２の少し下方に配置され、野縁材６の下部に取り付ける天井面材１０は構造材２の近くに敷設される。 After the hoisting material 6 is temporarily fixed to the receiving member 4 , the hoisting material 6 is fixed (permanently fixed) to the receiving member 4 using the clip member 8 . The clip member 8 is attached to the lower portion of the receiving member 4 . Thereby, the clip member 8 is arranged below the lower end portion of the side surface portion 14 of the structural member 2 . Moreover, the joist material 6 is arranged slightly below the structural material 2, and the ceiling surface material 10 attached to the lower part of the joist material 6 is laid near the structural material 2. - 特許庁

この場合、先ずクリップ部材８を受け部材４に取り付ける。クリップ部材８は、その背面部５０を受け部材４の該当する部位（野縁材６の中心上方）の前部に配置し、また側部５２，５２はそれぞれ野縁材６の側板部４４，４４の外側に配置する。そして、受け部材４の孔部２４を利用し、受け部材４側からネジ６２（又はボルト）を挿入し、クリップ部材８の背面部５０に設けたネジ孔部５８に螺着する。これで、受け部材４の下部側にクリップ部材８が取り付けられる。 In this case, the clip member 8 is first attached to the receiving member 4 . The clip member 8 has its back portion 50 arranged in front of the corresponding portion of the receiving member 4 (above the center of the hoisting member 6), and the side portions 52, 52 are the side plate portions 44 and 44 of the hoisting member 6, respectively. 44 outside. Using the hole 24 of the receiving member 4 , the screw 62 (or bolt) is inserted from the side of the receiving member 4 and screwed into the screw hole 58 provided in the rear surface portion 50 of the clip member 8 . The clip member 8 is now attached to the lower side of the receiving member 4 .

さらに、クリップ部材８の側部５２，５２の各孔部５５から、内側の野縁材６の側板部４４に向けてネジ６４を螺着する。これにより、クリップ部材８を介して、受け部材４の下部に野縁材６が接合（本固定）される。したがって野縁材６は、受け部材４の係止凹部２２により及びクリップ部材８を介して、受け部材４に支持され取り付けられる。
なお、野縁材６が傾斜して配置されていても、クリップ部材８の側部５２に対して、野縁材６の側板部４４は平面同士が合う形態であるため、両者の接合における前記傾斜による影響はない。 Further, a screw 64 is screwed from each hole 55 of the side portions 52, 52 of the clip member 8 toward the side plate portion 44 of the hoisting member 6 on the inner side. Thereby, the hoisting member 6 is joined (mainly fixed) to the lower part of the receiving member 4 via the clip member 8 .
