以下、この発明の実施の形態を添付図面に基づいて説明する。
図1(A)および図1(B)に示すように、この実施形態の天井下地構造1は、天井板(石こうボード等)11が取り付けられる天井下地フレーム2を、大梁12に設けられた支持部材13によって支持している。具体的には、上記支持部材13のクランプ部13aは、上記大梁12の下フランジ部に12aに固定されている。上記クランプ部13aの上部には、高さ調整螺子部13bが設けられており、この高さ調整螺子部13bの下部にはフレーム装着部13cが設けられている。そして、このフレーム装着部13cに上記天井下地フレーム2が下側から装着されている。上記大梁12には交差状に小梁14が固定されており、これらには、図示はしていないが、耐火被覆処理が施されている。
Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1 (A) and FIG. 1 (B), the ceiling foundation structure 1 of this embodiment is provided with a ceiling foundation frame 2 to which a ceiling board (gypsum board or the like) 11 is attached. It is supported by the member 13. Specifically, the clamp portion 13a of the support member 13 is fixed to the lower flange portion of the large beam 12 at 12a. A height adjusting screw portion 13b is provided at the upper portion of the clamp portion 13a, and a frame mounting portion 13c is provided at the lower portion of the height adjusting screw portion 13b. The ceiling base frame 2 is mounted on the frame mounting portion 13c from below. Small beams 14 are fixed to the large beams 12 so as to intersect with each other, and although not shown, a fireproof coating process is performed on them.

上記天井下地フレーム2は、第1フレーム部21と第2フレーム部22と備えており、四角形枠状に形成されている。上記第2フレーム部22の端部は箱曲げされており、上記第1フレーム部21の縦板部にカシメ留めされている。上記第1フレーム部21は、上記フレーム装着部13cに嵌め込まれている。上記天井下地フレーム2は、例えば、上記第1フレーム部21が3640mmで、上記第2フレーム部22が910mmの長方形状に形成される。   The ceiling base frame 2 includes a first frame portion 21 and a second frame portion 22 and is formed in a rectangular frame shape. The end portion of the second frame portion 22 is box-bent and is crimped to the vertical plate portion of the first frame portion 21. The first frame portion 21 is fitted into the frame mounting portion 13c. For example, the ceiling base frame 2 is formed in a rectangular shape in which the first frame portion 21 is 3640 mm and the second frame portion 22 is 910 mm.

上記第1フレーム部21は、上記大梁12の側に位置している。そして、上記第1フレーム部21は、上記大梁12の側に開口を有し且つ上リップ部および下リップ部を有している。   The first frame portion 21 is located on the large beam 12 side. The first frame portion 21 has an opening on the large beam 12 side and has an upper lip portion and a lower lip portion.

上記大梁12の長手方向と交差する方向に当該大梁12から離れて位置する隣り合う2枚の天井下地フレーム2、2は、天井下地連結部材3によって、連結されている。上記大梁12の芯から隣り合う2枚の天井下地フレーム2の上記第1フレーム部21の外端となる上下リップ部までの距離は、例えば83mm程度とされており、上記耐火被覆処理の影響を受けずに上記天井下地フレーム2の設置が行えるようにしている。   Two adjacent ceiling base frames 2 and 2 that are located away from the large beam 12 in a direction intersecting the longitudinal direction of the large beam 12 are connected by a ceiling base connecting member 3. The distance from the core of the large beam 12 to the upper and lower lip portions which are the outer ends of the first frame portion 21 of the two adjacent ceiling base frames 2 is, for example, about 83 mm. The ceiling base frame 2 can be installed without receiving.

上記天井下地連結部材3は、図2(A)、図2(B)および図2(C)に示すように、例えば、金属の板材をプレス加工することにより作製されている。上記天井下地連結部材3の本体部30は、断面が略コ字形状をなしている。そして、上記天井下地連結部材3は、上記第1フレーム部(チャンネル部材)21の上リップ部に係合する上切欠き部31を、一方の端側の上部側に2箇所、他方の端側の上部側に2箇所有しており、上記第1フレーム部21の下リップ部に係合する下切欠き部32を、一方の端側の下部側に2箇所、他方の端側の下部側に2箇所有している。   As shown in FIGS. 2A, 2B, and 2C, the ceiling base connecting member 3 is manufactured by, for example, pressing a metal plate material. The main body 30 of the ceiling base connecting member 3 has a substantially U-shaped cross section. The ceiling base connecting member 3 has two upper cutout portions 31 that engage with the upper lip portion of the first frame portion (channel member) 21 on the upper side of one end side and the other end side. The lower notch 32 that engages with the lower lip portion of the first frame portion 21 is provided at two locations on the lower side on one end side and on the lower side on the other end side. Has two locations.

上記上切欠き部31が上記第1フレーム部21の上リップ部に係合し、上記下切欠き部32が上記第1フレーム部21の下リップ部に係合することで、上記隣り合う2枚の天井下地フレーム2が連結される。この連結により、上記隣り合う2枚の天井下地フレーム2の間隔の精度は、上記一方の端側の切欠き部31(32)と上記他方の端側の切欠き部31(32)の精度により出ることになる。   The upper notch portion 31 engages with the upper lip portion of the first frame portion 21, and the lower notch portion 32 engages with the lower lip portion of the first frame portion 21, so that the two adjacent sheets The ceiling base frame 2 is connected. By this connection, the accuracy of the interval between the two adjacent ceiling base frames 2 depends on the accuracy of the notch 31 (32) on the one end side and the notch 31 (32) on the other end. Will come out.

上記天井下地連結部材3の幅Wは、上記第1フレーム部21における上記開口の幅(上リップ部先端と下リップ部先端の間隔)よりも狭くされている。このため、図3に示すように、上記天井下地連結部材3を、当該天井下地連結部材3が上記天井下地フレーム2を連結しているときの本来姿勢(図では実線で示している)に対して略90度回転させた状態(図では二点鎖線で示している)で、上記第1フレーム部21の開口に挿入することができる。   The ceiling base connecting member 3 has a width W that is narrower than the width of the opening in the first frame portion 21 (the distance between the tip of the upper lip and the tip of the lower lip). For this reason, as shown in FIG. 3, the ceiling base connecting member 3 is positioned relative to the original posture (shown by a solid line in the figure) when the ceiling base connecting member 3 connects the ceiling base frame 2. Then, it can be inserted into the opening of the first frame portion 21 in a state rotated by approximately 90 degrees (indicated by a two-dot chain line in the figure).

なお、上記天井下地連結部材3の長さは、隣り合う上記第1フレーム部21のリップ部間の間隔よりも長いので、上記開口への挿入は、上記天井下地連結部材3を鉛直軸回りに回してして行えばよい。   In addition, since the length of the ceiling base connecting member 3 is longer than the interval between the lip portions of the adjacent first frame parts 21, the insertion into the opening causes the ceiling base connecting member 3 to move around the vertical axis. Turn it around.

上記天井下地連結部材3を上述のようにして上記第1フレーム部21の開口に入れた後、この天井下地連結部材3を回転させることによって、上記天井下地連結部材3を上述した本来姿勢にする。このときに、上記上切欠き部31が上記上リップ部に係合され、上記下切欠き部32が上記下リップ部に係合されることになる。   After the ceiling base connecting member 3 is put into the opening of the first frame portion 21 as described above, the ceiling base connecting member 3 is brought into the original posture described above by rotating the ceiling base connecting member 3. . At this time, the upper notch portion 31 is engaged with the upper lip portion, and the lower notch portion 32 is engaged with the lower lip portion.

このように、隣り合う2枚の天井下地フレーム2が、上記天井下地連結部材3によって連結されるので、この連結のための螺子留めが不要になり、天井下地作製の作業時間を短縮することができる。   Thus, since two adjacent ceiling foundation frames 2 are connected by the ceiling foundation connecting member 3, screwing for this connection becomes unnecessary, and the work time for producing the ceiling foundation can be shortened. it can.

また、上記天井下地連結部材3を上述のように回転させることによって、上記上切欠き部31が上記上リップ部に係合され、上記下切欠き部32が上記下リップ部に係合される。すなわち、上記回転という簡単な作業により、当該天井下地連結部材3を上記天井下地フレーム2に係合させて、上記隣り合う2枚の天井下地フレーム2を連結することができる。   Further, by rotating the ceiling base connecting member 3 as described above, the upper notch portion 31 is engaged with the upper lip portion, and the lower notch portion 32 is engaged with the lower lip portion. That is, the two adjacent ceiling foundation frames 2 can be connected by engaging the ceiling foundation connecting member 3 with the ceiling foundation frame 2 by a simple operation of the rotation.

上記のように、上記天井下地連結部材3の上切欠き部31は、上記第1フレーム部21の長手方向に間隔をおいて2箇所に形成されているが、上記2箇所の上切欠き部31の間隔W1は、当該天井下地連結部材3の本体部30の幅Wよりも狭くされている(図2(A)参照)。これにより、上記天井下地連結部材を回転させる際に、上記第1フレーム部21の開口が無理に広げられるのを抑制することができる。上記上切欠き部31の間隔を狭くするには、上記本体部30の上面の延長面上に折れ線部を設定して、上記上切欠き部31が形成されている片部を斜めに折り曲げればよい。もちろん、上記上切欠き部31が形成されている片部を斜めに折り曲げることに限定されることはない。上記上切欠き部31の間隔狭くするために、上記上切欠き部31が形成されている片部を段形状に折り曲げてもよい。   As described above, the upper notch portions 31 of the ceiling base connecting member 3 are formed at two positions at intervals in the longitudinal direction of the first frame portion 21. The interval W1 of 31 is made narrower than the width W of the main body portion 30 of the ceiling base connecting member 3 (see FIG. 2A). Thereby, when rotating the said ceiling base connection member, it can suppress that opening of the said 1st frame part 21 is forcedly expanded. In order to narrow the interval between the upper notches 31, a fold line portion is set on the extended surface of the upper surface of the main body 30, and the one portion where the upper notches 31 are formed is bent obliquely. That's fine. Of course, it is not limited to bend the one part in which the said upper notch part 31 is formed diagonally. In order to narrow the interval between the upper notches 31, the piece on which the upper notches 31 are formed may be bent into a step shape.

また、上記2箇所の上切欠き部31の間隔W1が上記天井下地連結部材3の本体部30の幅Wよりも狭くされることに限らない。上記第1フレーム部21の長手方向に間隔をおいて2箇所に形成されている上記下切欠き部32の間隔を、当該天井下地連結部材3の本体部30の幅Wよりも狭くしてもよいものである。   Further, the interval W <b> 1 between the two upper notch portions 31 is not limited to be narrower than the width W of the main body portion 30 of the ceiling base connecting member 3. The interval between the lower notches 32 formed at two positions with an interval in the longitudinal direction of the first frame portion 21 may be narrower than the width W of the main body portion 30 of the ceiling foundation connecting member 3. Is.

ただし、上記2箇所の上切欠き部31の間隔W1を上記天井下地連結部材3の本体部30の幅Wよりも狭くする構造の方が、上記上切欠き部31が上記本体部30の上面板の近傍に位置するので、上記上切欠き部31に荷重が加わっても、当該天井下地連結部材3の変形は生じにくいし、また、上記天井下地連結部材3の本体部30の側板部にリブ33を形成することの妨げにもなりにくい。   However, in the structure in which the interval W1 between the two upper cutout portions 31 is narrower than the width W of the main body portion 30 of the ceiling base connecting member 3, the upper cutout portion 31 is located above the main body portion 30. Since it is located in the vicinity of the face plate, even if a load is applied to the upper notch 31, the ceiling base connecting member 3 is not easily deformed, and the ceiling base connecting member 3 has a side plate on the side plate portion of the main body 30. It is difficult to prevent the rib 33 from being formed.

上記天井下地連結部材3の本体部30の本体部30の側板部の各々の中央下部に係合部34を有してもよい。この係合部34の基部には横方向に入り込む切欠きが形成されており、天井下地となるチャンネル部材4のリップ付が上記切欠きに嵌まり、上記チャンネル部材4が上記係合部34に係合されることになる。上記係合部34に留め付けられた上記チャンネル部材4の下面は、上記第1フレーム部21の下面と略面一となる。上記チャンネル部材4の下面には上記天井板11を固定するための図示しないビスを打ち込むことができる。なお、上記チャンネル部材4の下面に間仕切り壁が設置される場合もある。   You may have the engaging part 34 in the center lower part of each side-plate part of the main-body part 30 of the main-body part 30 of the said ceiling base connection member 3. As shown in FIG. A notch is formed in the base of the engaging portion 34 so as to enter the lateral direction. A lip of the channel member 4 serving as a ceiling base is fitted into the notch, and the channel member 4 is formed in the engaging portion 34. Will be engaged. The lower surface of the channel member 4 fastened to the engaging portion 34 is substantially flush with the lower surface of the first frame portion 21. A screw (not shown) for fixing the ceiling plate 11 can be driven into the lower surface of the channel member 4. A partition wall may be provided on the lower surface of the channel member 4.

以上、図面を参照してこの発明の実施形態を説明したが、この発明は、図示した実施形態のものに限定されない。図示した実施形態に対して、この発明と同一の範囲内において、あるいは均等の範囲内において、種々の修正や変形を加えることが可能である。   As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
