上記のサンドイッチパネルＳを施工するにあたっては、１枚のサンドイッチパネルＳを胴縁等の下地材１００の屋外側面に配置し、第二凹段部１７の底面から釘やビス等の固定具４を打ち込んで、下地材１００にまで貫通する。ここで、サンドイッチパネルＳのうち固定具４を打ち込む箇所に充填する端部芯材３０を硬質な芯材とすることで、サンドイッチパネルＳを下地材１００に対して強固に固定することができる。次に、取り付けたサンドイッチパネルＳの上側から、他のサンドイッチパネルＳを近づけ、下側のサンドイッチパネルＳの嵌合凸部５に上側のサンドイッチパネルＳの嵌合凹部６を嵌合させる。この時、上側のサンドイッチパネルＳの折り返しスカート部１１は下側のサンドイッチパネルＳの収納部１６に位置して収納され、上側のサンドイッチパネルＳの屋内側第二折り返し部２２は下側のサンドイッチパネルＳの収納部２４に位置して収納される。以上のようにして上下に隣接するサンドイッチパネルＳを凹凸嵌合により接続しながら複数枚のサンドイッチパネルＳを縦横に並べて施工することで、外壁を形成できる。なお、固定具４の頭部４０は、頭部収納凹部１８内に納められると共にこの頭部４０は収納部１６に収納された折り返しスカート部１１で覆われるため、屋外側から見えなくできる。また、図示は省略しているが、上側のサンドイッチパネルＳの補強部１５と下側のサンドイッチパネルＳの補強部１９の間と、上側のサンドイッチパネルＳの補強部２５と下側のサンドイッチパネルＳの補強部２６の間と、屋外側嵌合凸部５０の上端面と屋外側嵌合凹部６０の底面（略水平部７０）との間と、屋内側嵌合凸部５１の上端面と屋内側嵌合凹部６１の底面（略水平部７２）との間には、セラミックファイバー等の耐火材や防水パッキンが挟まれる。これにより接続部分の耐火性や水密性を高めることができる。なお、上側のサンドイッチパネルＳの補強部１５と下側のサンドイッチパネルＳの補強部１９の間と、上側のサンドイッチパネルＳの補強部２５と下側のサンドイッチパネルＳの補強部２６の間に挟まれる耐火材は、補強部１５から補強部２５に亘って設けられることが好ましい。 In constructing the above sandwich panel S, one sandwich panel S is disposed on the outdoor side surface of the base material 100 such as the trunk edge, and the fixing tool 4 such as a nail or a screw is attached from the bottom surface of the second concave stepped portion 17. It is driven in and penetrates to the base material 100. Here, the sandwich panel S can be firmly fixed to the base material 100 by making the end core material 30 filled in the portion into which the fixture 4 is driven out of the sandwich panel S into a hard core material. Next, the other sandwich panel S is brought closer from the upper side of the attached sandwich panel S, and the fitting concave portion 6 of the upper sandwich panel S is fitted to the fitting convex portion 5 of the lower sandwich panel S. At this time, the folded skirt portion 11 of the upper sandwich panel S is stored in the receiving portion 16 of the lower sandwich panel S, and the indoor second folded portion 22 of the upper sandwich panel S is the lower sandwich panel. S is stored in the S storage section 24. The outer wall can be formed by arranging a plurality of sandwich panels S in the vertical and horizontal directions while connecting the sandwich panels S vertically adjacent to each other by the concave and convex fitting as described above. The head 40 of the fixture 4 is housed in the head housing recess 18 and the head 40 is covered with the folded skirt 11 housed in the housing 16, so that it cannot be seen from the outdoor side. Although not shown, between the reinforcing portion 15 of the upper sandwich panel S and the reinforcing portion 19 of the lower sandwich panel S, and between the reinforcing portion 25 of the upper sandwich panel S and the lower sandwich panel S. Between the reinforcing portions 26, between the upper end surface of the outdoor side fitting convex portion 50 and the bottom surface (substantially horizontal portion 70) of the outdoor side fitting concave portion 60, and the upper end surface of the indoor side fitting convex portion 51 and the roof. A refractory material such as ceramic fiber or waterproof packing is sandwiched between the bottom surface of the inner fitting recess 61 (substantially horizontal portion 72). Thereby, the fire resistance and water tightness of a connection part can be improved. It is sandwiched between the reinforcing part 15 of the upper sandwich panel S and the reinforcing part 19 of the lower sandwich panel S, and between the reinforcing part 25 of the upper sandwich panel S and the reinforcing part 26 of the lower sandwich panel S. It is preferable that the refractory material to be provided extends from the reinforcing portion 15 to the reinforcing portion 25.

以上のようにして嵌合凸部５と嵌合凹部６との凹凸嵌合によって接続されたサンドイッチパネルＳでは、屋外側嵌合凸部５０の屋内側面５２の被係止用凹部８と、屋外側嵌合凹部６０の屋内側の側壁６３の屋外側面６４の係止用凸部７とが、パネル厚み方向に距離をおいて対向している。 In the sandwich panel S connected by the concave / convex fitting between the fitting convex portion 5 and the fitting concave portion 6 as described above, the locked concave portion 8 on the indoor side surface 52 of the outdoor side fitting convex portion 50, The engaging convex portion 7 of the outdoor side surface 64 of the indoor side wall 63 of the outer fitting concave portion 60 is opposed to the panel thickness direction with a distance.

この接続状態にあるサンドイッチパネルＳでは、サンドイッチパネルＳは、上端部は固定具４によって下地材１００に固定されているものの、下端部は凹凸嵌合によってのみ保持されている。そのため、この接続状態にあるサンドイッチパネルＳに負の風荷重が強くかかると、図２に示すように、上側のサンドイッチパネルＳの下端部が、下側のサンドイッチパネルＳとの嵌合位置から屋外側上方へとずれる場合がある。 In the sandwich panel S in this connected state, the sandwich panel S has its upper end fixed to the base material 100 by the fixture 4, but its lower end is held only by uneven fitting. Therefore, when a negative wind load is applied to the sandwich panel S in this connected state, the lower end portion of the upper sandwich panel S is opened from the fitting position with the lower sandwich panel S as shown in FIG. There may be a case where it shifts outward and upward.

このように上側のサンドイッチパネルＳの下端部が屋外側へとずれる場合に、本実施形態では、屋外側嵌合凹部６０に設けた係止用凸部７が、屋外側嵌合凸部５０に設けた被係止用凹部８に係止される。これにより、本実施形態では、上側のサンドイッチパネルＳの下端部の嵌合凹部６が、下側のサンドイッチパネルＳの上端部の嵌合凸部５を屋外側へと乗り越えることを抑制でき、接続状態にある２枚のサンドイッチパネルＳの接続が外れてしまうことを抑制できる。なお、上述のように屋外側端縁部１２と屋内側端縁部２３の間に充填する端部芯材３０を硬質な芯材とすることで、被嵌合凹部８に係止する際の係止用凸部７の変形を抑制できるため、被係止用凹部８に対して係止用凸部７をより確実に係止させることができる。 Thus, when the lower end part of the upper sandwich panel S is shifted to the outdoor side, in this embodiment, the locking convex part 7 provided in the outdoor side fitting concave part 60 becomes the outdoor side fitting convex part 50. It is locked in the provided recessed portion 8 to be locked. Thereby, in this embodiment, it can suppress that the fitting recessed part 6 of the lower end part of the upper sandwich panel S gets over the fitting convex part 5 of the upper end part of the lower sandwich panel S to the outdoor side, and is connected. It is possible to suppress the disconnection of the two sandwich panels S in the state. As described above, the end core member 30 filled between the outdoor side edge portion 12 and the indoor side edge portion 23 is a hard core material, so that it can be locked in the mating recessed portion 8. Since the deformation of the locking projection 7 can be suppressed, the locking projection 7 can be more reliably locked to the locked recess 8.

また、本実施形態においては、嵌合凸部５（屋外側嵌合凸部５０）の屋内側面５２のうち、上部ではなく下部に被係止用凹部８を設けたことで、ここに係止する係止用凸部７を下部に備えた嵌合凹部６（屋外側嵌合凹部６０）が、接続状態にあるサンドイッチパネルＳに負の風荷重が強くかかった場合に、上方へとずれにくい。そのため、嵌合凸部５（屋外側嵌合凸部５０）の屋内側面５２のうち、嵌合凹部６（屋外側嵌合凹部６０）によって屋外側へ押される箇所が、上方へとずれることを抑制でき、この嵌合凸部５（屋外側嵌合凸部５０）を屋外側に倒す方向にかかるモーメントが大きくなることを抑えることができる。これにより、本実施形態では嵌合凸部５（屋外側嵌合凸部５０）が屋外側へと倒れにくく、接続状態にある２枚のサンドイッチパネルＳの接続がより外れにくくなっている。 Moreover, in this embodiment, it is locked here by providing the recessed portion 8 to be locked in the lower portion, not the upper portion, of the indoor side surface 52 of the fitting convex portion 5 (outdoor fitting convex portion 50). The fitting concave portion 6 (outdoor fitting concave portion 60) having the locking convex portion 7 to be lower does not easily shift upward when a negative wind load is strongly applied to the sandwich panel S in a connected state. . Therefore, in the indoor side surface 52 of the fitting convex portion 5 (outdoor side fitting convex portion 50), the portion pushed to the outdoor side by the fitting concave portion 6 (outdoor side fitting concave portion 60) is shifted upward. It can suppress, and it can suppress that the moment concerning the direction which falls this fitting convex part 5 (outdoor side fitting convex part 50) to the outdoor side becomes large. Thereby, in this embodiment, the fitting convex part 5 (outdoor side fitting convex part 50) is hard to fall down to the outdoor side, and the connection of the two sandwich panels S in a connected state is harder to come off.

なお、本実施形態では、係止用凸部７と被係止用凹部８とは、嵌合凸部５と嵌合凹部６とが嵌合した嵌合位置において、サンドイッチパネルＳの厚み方向にずれて上下に重ならない位置関係となるように形成されている。そのため、鉛直下向きに嵌合凹部６を嵌合凸部５に嵌め込む際や、鉛直上向きに嵌合凸部５から嵌合凹部６を引き抜く際に、係止用凸部７が嵌合凹部６に引っ掛かりにくい。これにより、本実施形態では、隣接するサンドイッチパネルＳの接続や、位置調整等のための隣接するサンドイッチパネルＳの接続解除を、係止用凸部７に邪魔されることなく、簡単に行うことができる。 In this embodiment, the locking convex portion 7 and the locked concave portion 8 are arranged in the thickness direction of the sandwich panel S at the fitting position where the fitting convex portion 5 and the fitting concave portion 6 are fitted. It is formed so as to have a positional relationship that is shifted and does not overlap vertically. Therefore, when the fitting concave portion 6 is fitted into the fitting convex portion 5 vertically downward, or when the fitting concave portion 6 is pulled out from the fitting convex portion 5 vertically upward, the locking convex portion 7 is fitted into the fitting concave portion 6. It is hard to get caught in. Thereby, in this embodiment, connection of adjacent sandwich panels S and connection release of adjacent sandwich panels S for position adjustment etc. are easily performed without being obstructed by the locking projections 7. Can do.

続いて、図３に示す第二実施形態のサンドイッチパネルＳの接続構造について説明する。第二実施形態では、補強片９を備えている点でのみ第一実施形態と異なる。なお、図３には、第一実施形態のサンドイッチパネルＳと同じ構成には同じ符号をつけている。 Subsequently, a connection structure of the sandwich panel S of the second embodiment shown in FIG. 3 will be described. The second embodiment differs from the first embodiment only in that the reinforcing piece 9 is provided. In FIG. 3, the same components as those of the sandwich panel S of the first embodiment are denoted by the same reference numerals.

補強片９は、図３（ａ）に示すように、最も屋外側に位置する嵌合凸部５（つまりは屋外側嵌合凸部５０）の屋外側面５３に配置されて、この嵌合凸部５（屋外側嵌合凸部５０）が屋外側に倒れることを防止する。詳しくは、補強片９は、図３（ａ）及び図３（ｂ）に示すように、第二凹段部１７の屋外側面（底面）に固定される固定板部９０と、屋外側折り返し部１４の屋外側面５３に沿うように配置される抑え板部９１とを備える。固定板部９０と抑え板部９１とは連続して一体に形成されており、固定板部９０には固定具４が挿通される挿通孔９２が設けられている。 As shown in FIG. 3A, the reinforcing piece 9 is disposed on the outdoor side surface 53 of the fitting convex portion 5 (that is, the outdoor-side fitting convex portion 50) located on the most outdoor side. The part 5 (outdoor side fitting convex part 50) is prevented from falling to the outdoor side. Specifically, as shown in FIGS. 3A and 3B, the reinforcing piece 9 includes a fixed plate portion 90 fixed to the outdoor side surface (bottom surface) of the second concave stepped portion 17, and an outdoor side folded portion. 14, and a holding plate portion 91 arranged along the outdoor side surface 53. The fixed plate portion 90 and the holding plate portion 91 are integrally formed continuously, and the fixed plate portion 90 is provided with an insertion hole 92 through which the fixture 4 is inserted.

補強片９は、固定具４によって固定板部９０が第二凹段部１７の屋外側面に固定されると、抑え板部９１が屋外側折り返し部１４の屋外側面５３の屋外側に位置する。これにより、サンドイッチパネルＳに負の風荷重がかかった際、この補強片９によって屋外側嵌合凸部５０が屋外側嵌合凹部６０の屋内側の側壁６３に押されて屋外側へと倒れることを抑制できる。ここで、屋外側嵌合凸部５０を屋外側へと倒れにくくしたことで、屋外側嵌合凸部５０に備える被係止用凹部８が変形しにくく、被係止用凹部８と係止用凸部７との係止強さを確保できる。また、屋外側嵌合凸部５０を屋外側へと倒れにくくしたことで、屋外側嵌合凸部５０が倒れて屋外側嵌合凸部５０の上下長さが短くなることを防止できるため、屋外側嵌合凹部６０と屋外側嵌合凸部５０との嵌合深さを確保できる。このように係止強さと嵌合深さとを確保することで、第二実施形態のサンドイッチパネルＳの接続構造では、負の風荷重によって、凹凸嵌合により接続したサンドイッチパネルの接続が外れてしまうことをさらに抑制することができる。 When the fixing plate 90 is fixed to the outdoor side surface of the second concave stepped portion 17 by the fixture 4, the reinforcing plate 9 is positioned on the outdoor side of the outdoor side surface 53 of the outdoor side folded portion 14. Accordingly, when a negative wind load is applied to the sandwich panel S, the outdoor side fitting convex portion 50 is pushed by the indoor side wall 63 of the outdoor side fitting concave portion 60 by the reinforcing piece 9 and falls to the outdoor side. This can be suppressed. Here, by making the outdoor side fitting convex portion 50 difficult to fall to the outdoor side, the locked recess portion 8 included in the outdoor side fitting convex portion 50 is not easily deformed, and is locked with the locked recess portion 8. The locking strength with the convex portion 7 can be ensured. In addition, by making the outdoor side fitting convex part 50 difficult to fall to the outdoor side, it is possible to prevent the outdoor side fitting convex part 50 from falling and shortening the vertical length of the outdoor side fitting convex part 50. The fitting depth of the outdoor side fitting recessed part 60 and the outdoor side fitting convex part 50 is securable. By securing the locking strength and the fitting depth in this way, in the sandwich panel S connection structure of the second embodiment, the connection of the sandwich panel connected by the concave-convex fitting is disconnected due to a negative wind load. This can be further suppressed.

なお、上述した第一実施形態のサンドイッチパネルＳでは、屋外側嵌合凸部５０に被係止用凹部８を設け、屋外側嵌合凹部６０に係止用凸部７を設けていたが、係止用凸部７と被係止用凹部８とを設ける位置はこれに限らない。 In the sandwich panel S of the first embodiment described above, the locked concave portion 8 is provided in the outdoor-side fitting convex portion 50, and the locking convex portion 7 is provided in the outdoor-side fitting concave portion 60. The position where the locking convex part 7 and the locked concave part 8 are provided is not limited to this.

すなわち、図４（ａ）に示す第三実施形態のサンドイッチパネルＳのように、屋外側嵌合凸部５０ではなく屋内側嵌合凸部５１に被係止用凹部８を設け、屋外側嵌合凹部６０ではなく屋内側嵌合凹部６１に係止用凸部７を設けるようにしてもよい。つまり、屋内側嵌合凸部５１の屋内側面５２に被係止用凹部８を備え、屋内側嵌合凹部６１の屋内側の側壁６３の屋外側面６４に係止用凸部７を備えるようにしてもよい。なお、図４（ａ）には、第一実施形態のサンドイッチパネルＳと同じ構成には同じ符号をつけている。このような構成とすることによっても、凹凸嵌合により接続したサンドイッチパネルＳの接続が外れてしまうことを抑制できる。また、図４（ａ）には図示していないが、補強片９を屋外側嵌合凸部５０の屋外側面５３に取り付け、接続が外れることをさらに抑制するようにしてもよい。なお、第二凹段部１７の屋内側に充填する端部芯材３０を硬質な芯材とすることで、この端部芯材３０を土台とする屋内側第一折り返し部２１の強度を向上させて、嵌合の際にこの屋内側第一折り返し部２１に備える被係止用凹部８が変形することを抑制できる。 That is, like the sandwich panel S of the third embodiment shown in FIG. 4A, the recessed portion 8 to be locked is provided not on the outdoor side fitting convex portion 50 but on the indoor side fitting convex portion 51, and the outdoor side fitting is performed. You may make it provide the convex part 7 for a latch not in the joint recessed part 60 but the indoor side fitting recessed part 61. FIG. That is, the recessed portion 8 to be locked is provided on the indoor side surface 52 of the indoor side fitting convex portion 51, and the locking convex portion 7 is provided on the outdoor side surface 64 of the indoor side wall 63 of the indoor side fitting concave portion 61. May be. In FIG. 4A, the same reference numerals are given to the same components as those of the sandwich panel S of the first embodiment. Also by setting it as such a structure, it can suppress that the connection of the sandwich panel S connected by uneven | corrugated fitting will remove | deviate. Although not shown in FIG. 4A, the reinforcing piece 9 may be attached to the outdoor side surface 53 of the outdoor side fitting convex portion 50 to further suppress disconnection. In addition, the strength of the indoor side first folded portion 21 using the end core material 30 as a base is improved by using the end core material 30 filling the indoor side of the second concave step portion 17 as a hard core material. Thus, it is possible to suppress deformation of the locked recessed portion 8 provided in the indoor first folded portion 21 during fitting.

また、図４（ｂ）に示す第四実施形態のサンドイッチパネルＳのように、屋外側嵌合凸部５０と屋内側嵌合凸部５１の両方に被係止用凹部８を設け、屋外側嵌合凹部６０と屋内側嵌合凹部６１の両方に係止用凸部７を設けるようにしてもよい。つまり、屋外側嵌合凸部５０と屋内側嵌合凸部５１の屋内側面５２に被係止用凹部８を備え、屋外側嵌合凹部６０と屋内側嵌合凹部６１の屋内側の側壁６３の屋外側面６４に係止用凸部７を備えるようにしてもよい。なお、図４（ｂ）には、第一実施形態のサンドイッチパネルＳと同じ構成には同じ符号をつけている。このような構成とすることで、２箇所で係止することとなり、凹凸嵌合により接続したサンドイッチパネルの接続が外れてしまうことをさらに抑制することができる。また、図４（ｂ）には図示していないが、補強片９を屋外側嵌合凸部５０の屋外側面５３に取り付けて、接続が外れることをさらに抑制するようにしてもよい。なお、屋外側端縁部１２と屋内側端縁部２３の間に充填する端部芯材３０を硬質な芯材とすることで、屋外側の被嵌合凹部８に係止する際の係止用凸部７の変形を抑制できるため、この被係止用凹部８に対して係止用凸部７をより確実に係止させることができる。また、第二凹段部１７の屋内側に充填する端部芯材３０を硬質な芯材とすることで、この端部芯材３０を土台とする屋外側折り返し部１４と屋内側第一折り返し部２１の強度を向上させて、嵌合の際にこの屋外側折り返し部１４と屋内側第一折り返し部２１にそれぞれ備える被係止用凹部８が変形することを抑制できる。 Moreover, like the sandwich panel S of the fourth embodiment shown in FIG. 4B, the recessed portions 8 to be locked are provided on both the outdoor side fitting convex portion 50 and the indoor side fitting convex portion 51, and the outdoor side The locking convex portion 7 may be provided in both the fitting concave portion 60 and the indoor side fitting concave portion 61. That is, the recessed portion 8 to be locked is provided on the indoor side surface 52 of the outdoor side fitting convex portion 50 and the indoor side fitting convex portion 51, and the side wall 63 on the indoor side of the outdoor side fitting concave portion 60 and the indoor side fitting concave portion 61. You may make it equip the outdoor side surface 64 of this with the convex part 7 for latching. In FIG. 4B, the same reference numerals are given to the same components as those of the sandwich panel S of the first embodiment. By setting it as such a structure, it will latch at two places and it can further suppress that the connection of the sandwich panel connected by uneven | corrugated fitting will remove | deviate. Although not shown in FIG. 4B, the reinforcing piece 9 may be attached to the outdoor side surface 53 of the outdoor-side fitting convex portion 50 to further suppress disconnection. Note that the end core member 30 filled between the outdoor side edge portion 12 and the indoor side edge portion 23 is a hard core material, so that the engagement with the recessed portion 8 on the outdoor side can be performed. Since the deformation of the locking projection 7 can be suppressed, the locking projection 7 can be more reliably locked to the locked recess 8. In addition, the end core member 30 that fills the indoor side of the second concave step portion 17 is a hard core member, so that the outdoor-side folded portion 14 and the indoor-side first folded portion having the end core member 30 as a base are used. The strength of the portion 21 can be improved, and deformation of the locked recesses 8 provided in the outdoor side folded portion 14 and the indoor side first folded portion 21 during fitting can be suppressed.

以上まとめると、第一乃至第四実施形態のサンドイッチパネルの接続構造では、２枚の金属板１，２の間に芯材３を介装したサンドイッチパネルＳの一方の端部に複数の嵌合凸部５をパネル厚み方向に所定の間隔をおいて設けている。このサンドイッチパネルＳの他方の端部に複数の嵌合凹部６をパネル厚み方向に所定の間隔をおいて設けている。隣接する２枚のサンドイッチパネルＳを嵌合凸部５と嵌合凹部６との嵌合により接続している。そして、少なくとも１つの嵌合凹部６の屋内側の側壁６３の屋外側面６４に係止用凸部７を設け、この嵌合凹部６に嵌合する嵌合凸部５の屋内側面５２に、この嵌合凹部６が嵌合位置から屋外側にずれた際に係止用凸部７が係止される被係止用凹部８を設けている。 In summary, in the sandwich panel connection structure of the first to fourth embodiments, a plurality of fittings are provided at one end of the sandwich panel S in which the core material 3 is interposed between the two metal plates 1 and 2. Protrusions 5 are provided at predetermined intervals in the panel thickness direction. A plurality of fitting recesses 6 are provided at predetermined intervals in the panel thickness direction at the other end of the sandwich panel S. Two adjacent sandwich panels S are connected by fitting the fitting convex part 5 and the fitting concave part 6 together. And the convex part 7 for latching is provided in the outdoor side surface 64 of the indoor side wall 63 of the at least one fitting concave part 6, and the indoor side surface 52 of the fitting convex part 5 fitted to the fitting concave part 6 A locked recess 8 is provided to which the locking projection 7 is locked when the fitting recess 6 is shifted from the fitting position to the outdoor side.

このような構成とすることで、嵌合により接続された２枚のサンドイッチパネルＳに負の風荷重がかかった際に、嵌合凹部６が嵌合位置から屋外側にずれると、嵌合凹部６に設けた係止用凸部７が嵌合凸部５に設けた被係止用凹部８に係止される。このように負の風荷重がかかった場合に嵌合凹部６が嵌合凸部５に係止されるようにしたことで、嵌合凹部６が嵌合凸部５を屋外側に乗り越えることを抑制でき、凹凸嵌合による接続が外れにくくなっている。 With such a configuration, when a negative wind load is applied to the two sandwich panels S connected by fitting, when the fitting recess 6 is shifted from the fitting position to the outdoor side, the fitting recess The locking projection 7 provided on 6 is locked to the locked recess 8 provided on the fitting projection 5. In this way, when the negative wind load is applied, the fitting concave portion 6 is locked to the fitting convex portion 5 so that the fitting concave portion 6 gets over the fitting convex portion 5 to the outdoor side. It is possible to suppress the connection due to the uneven fitting, and it is difficult to disconnect.

また、第二実施形態のサンドイッチパネルの接続構造では、複数の嵌合凸部５のうち最も屋外側に位置する嵌合凸部５の屋外側面５３に、この嵌合凸部５が屋外側に倒れることを防止するための補強片９を取り付けている。 Moreover, in the connection structure of the sandwich panel of the second embodiment, among the plurality of fitting projections 5, the fitting projection 5 is arranged on the outdoor side of the fitting projection 5 located on the most outdoor side. A reinforcing piece 9 for preventing the body from falling is attached.

このような構成とすることで、嵌合により接続された隣接する２枚のサンドイッチパネルＳに負の風荷重がかかった際に、嵌合凹部６の屋内側の側壁６３が最も屋外側に位置する嵌合凸部５を屋外側に押し倒そうとした場合に、補強片９によって嵌合凸部５が屋外側に倒れることを防止できる。このように最も屋外側に位置する嵌合凸部５を屋外側へと倒れにくいようにすることで、嵌合凸部５に設けた被係止用凹部８と嵌合凹部６に設けた係止用凸部７が、強く係止し合うことを促進できる。また、嵌合凹部６と嵌合凸部５との嵌合深さが浅くなることも抑制できる。このように係止強さを確保するとともに嵌合凹部６と嵌合凸部５との嵌合深さを確保することによって、第二実施形態のサンドイッチパネルの接続構造では、嵌合凹部６が嵌合凸部５を屋外側へと乗り越えることをより抑制でき、凹凸嵌合による接続がさらに外れにくくできる。 By adopting such a configuration, when a negative wind load is applied to two adjacent sandwich panels S connected by fitting, the indoor side wall 63 of the fitting recess 6 is located on the most outdoor side. When the fitting convex portion 5 to be pushed is pushed down to the outdoor side, the fitting convex portion 5 can be prevented from falling to the outdoor side by the reinforcing piece 9. In this way, the engagement convex portion 5 located on the most outdoor side is made difficult to fall to the outdoor side, so that the engagement concave portion 8 provided on the fitting convex portion 5 and the engagement concave portion 6 are provided. It can accelerate | stimulate that the convex part 7 for a stop strongly latches. Moreover, it can also suppress that the fitting depth of the fitting recessed part 6 and the fitting convex part 5 becomes shallow. In this way, in the sandwich panel connection structure of the second embodiment, the fitting recess 6 is formed by securing the engagement strength and securing the fitting depth between the fitting recess 6 and the fitting projection 5. It is possible to further suppress the fitting convex portion 5 from getting over to the outdoor side, and the connection due to the concave-convex fitting can be further prevented from coming off.

なお、上述の説明では、嵌合凸部５と嵌合凹部６をそれぞれ２つずつ備えたサンドイッチパネルＳについて説明したが、サンドイッチパネルＳは、嵌合凸部５と嵌合凹部６とを３つずつまたはそれ以上備えていてもかまわない。 In the above description, the sandwich panel S having two fitting protrusions 5 and two fitting recesses 6 has been described. However, the sandwich panel S includes three fitting protrusions 5 and three fitting recesses 6. You may have one or more.

また、係止構造（係止用凸部及び被係止用凹部）は、嵌合により接続するサンドイッチパネルの嵌合凸部と嵌合凹部のうち、負の風荷重がかかった際に接触する箇所に設ければよく、嵌合凸部と嵌合凹部の形状に合わせて、係止構造を設ける箇所は多様に変更できる。 Further, the locking structure (the locking convex portion and the locked concave portion) comes into contact when a negative wind load is applied between the fitting convex portion and the fitting concave portion of the sandwich panel to be connected by fitting. What is necessary is just to provide in a location, and the location which provides a latching structure can be variously changed according to the shape of a fitting convex part and a fitting recessed part.

以上、本発明を添付図面に示す実施形態に基づいて説明したが、本発明は上記の各実施形態に限定されるものではなく、本発明の意図する範囲内であれば、適宜の設計変更が可能である。 Although the present invention has been described based on the embodiments shown in the accompanying drawings, the present invention is not limited to the above-described embodiments, and appropriate design changes can be made within the intended scope of the present invention.
