In addition, a receiving recess 24 is provided at a portion in the middle of the longitudinal direction of the horizontal member 11 where objects to be joined having a relatively small vertical dimension (the fourth beam 37 and the fifth beam 38 in FIG. 1) are joined. It does not have to be (see also FIG. 5).
In addition, when the partition wall 9 (see FIG. 1) is joined in the middle of the wall panel 1 in the wall width direction, the upper end side member 23 is provided with a missing portion so that the partition wall 9 can be received. 24A may be provided as a receiving recess (see FIG. 5). In other words, it is also possible to adopt a configuration in which the cutout portion 24A for receiving the partition wall 9 is provided by dividing the upper end side member 23 in the longitudinal direction midway in the wall width direction. In the illustrated example, an example is shown in which a missing portion 24A is provided in the middle of the longitudinal direction of the upper end side member 23 of the second wall panel 1B. The cutout portion 24A is provided so as to cut the upper end side member 23 over the entire vertical direction.

Further, in the illustrated example, the upper end side member 23 of the wall panel 1 shows an example in which a plurality of face members are formed in the wall width direction, and the adjacent side ends of these face members form the bottom of the receiving recess 24. It shows an example in which side parts are partitioned. In other words, a projecting portion for partitioning the bottom side portion of the receiving recess 24 is provided at the adjacent side end portions of the plurality of face members forming the upper end side member 23 .
The dimension along the wall width direction of each face member forming the upper end side member 23 may be the same as the width dimension of the standard dimension face members (outer wall side member 21 and lower side member 29). The thickness dimension of the upper end side member 23 may be about 9 mm to 25 mm, or may be 12 mm or more.
Instead of the above-described mode, a projecting portion that defines the bottom side portion of the receiving recess 24 is provided only on one adjacent side end of the side members adjacent in the wall width direction that constitute the upper end side member 23. It is good also as a structure provided. Alternatively, a configuration in which a face member for partitioning the bottom side portion of the receiving recess 24 is provided between adjacent side end portions of adjacent face members provided at intervals in the wall width direction constituting the upper end side member 23. may be
壁パネル１の第１柱材１２Ａに、当該壁パネル１とによって屋内側に入隅部を形成するように直交状に他の壁パネル１が接合される場合には、上端側面材２３の柱材側端部２６Ａを第１柱材１２Ａに重なり合わないように壁幅方向内側に位置させた構成としてもよい（図２（ａ）及び図５参照）。このように上端側面材２３の柱材側端部２６Ａを第１柱材１２Ａに重なり合わないように壁幅方向内側に位置させて欠落させた部位を受入凹所として把握してもよい。図例では、第１壁パネル１Ａ及び第３壁パネル１Ｃの上端側面材２３の柱材側端部２６Ａを第１柱材１２Ａに重なり合わないように壁幅方向内側に位置させた構成とした例を示している。
上端側面材２３に設けられる受入凹所２４や受入凹所を構成する欠落部２４Ａとしては、上記のような構成に限られず、接合対象に応じて適宜の変形が可能である。
When another wall panel 1 is joined orthogonally to the first pillar material 12A of the wall panel 1 so as to form an internal corner on the indoor side with the wall panel 1, the pillar of the upper end side material 23 The material side end portion 26A may be positioned inside in the wall width direction so as not to overlap the first pillar material 12A (see FIGS. 2(a) and 5). In this way, the pillar-side end portion 26A of the upper end side member 23 may be positioned inward in the wall width direction so as not to overlap the first pillar 12A, and the removed portion may be grasped as a receiving recess. In the illustrated example, the pillar member side end portions 26A of the upper end side members 23 of the first wall panel 1A and the third wall panel 1C are positioned inside in the wall width direction so as not to overlap the first pillar member 12A. shows an example.
The receiving recesses 24 provided in the upper end side member 23 and the missing portions 24A forming the receiving recesses are not limited to the configurations described above, and can be appropriately modified according to the objects to be joined.

An example of holding down is shown. The longitudinal ends of the joists 31 are held by the other joists 30 arranged orthogonally to the joists 31 and the joists 30 provided on both sides in the wall thickness direction of the partition wall 9. good. In other words, the edge 30 may function as a ceiling hook. The ceiling base for holding the ceiling material 7 is not limited to the steel base as shown in the figure, but may be a wooden base, and other various modifications are possible. Further, instead of providing the wall panel 1 with the edge 30 as described above in advance, the wall panel 1 may be fixed at the construction site.
開口部１９が設けられたパネル枠体１０の壁厚方向一方面には、図５に示すように、開口部１９を囲むように開口周囲面材２７が固定されている。このような構成とすれば、施工現場において開口部１９を囲むように切断等して面材を固定する必要がなく、施工性を向上させることができる。この開口周囲面材２７と上端側面材２３とは、パネル高さ方向に隣接して設けられている。このような構成とすれば、開口周囲面材２７と上端側面材２３との間に施工現場において面材を固定する必要がなく、施工性を向上させることができる。

With such a configuration, there is no need to fix the face material by cutting or the like so as to surround the opening 19 at the construction site, and workability can be improved. The opening surrounding surface member 27 and the upper end side surface member 23 are provided adjacent to each other in the panel height direction. With such a configuration, there is no need to fix a face member between the opening surrounding face member 27 and the upper end side face member 23 at the construction site, and workability can be improved.
The opening-surrounding surface member 27 is fixed in advance to the panel frame 10 by an appropriate fastener, with the upper end surface abutting against the lower end surface of the upper end side surface member 23 .
