DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. One embodiment of the present invention is shown in FIGS. As shown in FIG. 2, a part of the outer wall surface of the building A is retracted inward to form a setback space 1 such as a front porch. In the embodiment shown in the drawing, the setback space 1 is formed by retracting the outer wall surfaces of the corner portion of the building A that are adjacent to each other at right angles to the inside. This building A is constructed by the panel construction method, and the outer wall surface is the adjacent outer wall panel 3
They are configured by connecting each other with a connecting metal piece 10. Then, the upper end portions of both outer wall panels 3 which constitute the non-retracted portion of the outer wall surface and whose side end portions are located at the inlet 2 side end portion of the setback space 1 intersect the extension lines of both outer wall panels 3. Beams 5 are connected to the independent columns 4 that are erected in the portions (that is, the corners of the building A). That is, according to the present invention, the set-back inlet configuration in which the vertical wall panel portion 31 is integrally connected to the panel body portion 30 laterally from the upper end of the side end portion of the conventional panel body portion 30 as shown in FIG. It is characterized in that, instead of the outer wall panel 31 for use, the wall surface of this portion is divided into a rectangular non-open outer wall panel 3 and a beam 5 connected thereto. By dividing the outer wall panel 3 and the beams 5 in this way, the outer wall panel 32 for the setback entrance configuration having a special shape and structure as in the related art is not required, and the manufacturing, transportation, and construction can be simplified. It is like this.

The outer wall panel 3 is constructed by attaching a structural face plate 7 to a frame member 6, and as shown in FIGS. 5 and 6, an end plate 11 provided at one end of the beam 5 is attached to the outer wall panel 3. Frame material 6
7, the end plate 11 is provided on the other end portion of the beam 5 in the same manner as the independent column 4 as shown in FIG. 1
It is fixed by 2.

When a part of the outer wall surface of the building A of the panel construction method is retracted inward to form the setback space 1, the wall surface at the corner of the setback space 1 is as shown in FIGS. 1 and 3. The setback outer wall panel 8 is used. Similar to the outer wall panel 3, the setback outer wall panel 8 is also constructed by attaching the structural face plate 7 to the frame member 6, and two setback outer wall panels 8 forming the corners of the setback space 1. The one side ends are connected to each other at right angles by the connection hardware 10. The other ends of the setback outer wall panels 8 connected at right angles are connected to the inlet side end of the setback space 1 of the outer wall panel 3, respectively. To connect the other end of the setback outer wall panel 8 to the inlet side end of the setback space 1 of the outer wall panel 3 at right angles to this, for example, as shown in FIG. 4 and FIG. The upper end of the side end portion is brought into contact with the side surface of the beam 5 near the connection portion with the outer wall panel 3 and fixed by the bolt 12, so that the upper end portion of the other end of the setback outer wall panel 8 is fixed to the outer wall panel 3. The other end of the setback outer wall panel 8 is connected to the other end of the setback via a beam 5, and the lower end of the other end of the setback outer wall panel 8 is connected to the outer wall panel 3 by a bolt 12 via a connection metal fitting 10. . Here, the connecting metal fitting 10 for connecting the lower end of the other side end of the setback outer wall panel 8 and the lower end of the side end of the outer wall panel 3 is fixed to the foundation 15 by anchor bolts 16. In this case, the inlet side end of the setback space 1 of the outer wall panel 3 and the other end of the setback outer wall panel 8 may be directly connected.

Here, when the outer wall panel 3 and the beam 5 are divided, when an out-of-plane force such as seismic force or wind pressure acts as shown by arrows a and b in FIG. As described above, the outer wall panel 3, the beam 5, and the connecting portion of the beam may be deformed, but in the present invention, as described above, the set is a structural panel in which the structural face plate 7 is attached to the frame member 6. By connecting the side end portion of the back outer wall panel 8 to the side end portion of the outer wall panel 3, an out-of-plane force such as seismic force or wind pressure, which is indicated by arrows a and b in FIG. 8A, acts. Also, the setback outer wall panel 8 which is a structural panel can firmly support the end portion of the setback space 1 on the inlet 2 side of the outer wall panel 3 including the connecting portion between the outer wall panel 3 and the beam 5, whereby the outer wall Even though the panel 3 and the beam 5 are divided and connected, a set bar for the outer wall panel 3 is provided. So that the inlet 2 side end portion of the click space 1 is prevented from being deformed.

Another embodiment of the present invention is shown in FIGS. In this embodiment, the upper ends of two setback outer wall panels 8 that are connected at a right angle and form the wall surface of the set corner portion of the setback space 1 are connected by a hitting material 9. Both ends of the flint material 9 are connected to the upper end of the end opposite to the end connecting the two setback outer wall panels 8 to each other. In this way, by connecting the upper ends of the two setback outer wall panels 8 with the fired material 9, the upper parts of the two setback outer wall panels 8 and the fired material 9 are connected.
Thus, a so-called triangular truss structure is formed. As a result, even if an out-of-plane force such as seismic force or wind pressure is applied, the truss structure prevents the connecting portion between the outer wall panel 3 and the beam 5 from being further deformed. For this reason, even if the setback outer wall panel 8 is formed with an opening 19 such as a doorway, the reinforcing effect against the out-of-plane force is high and the end portion of the outer wall panel 3 on the inlet 2 side of the setback space 1 is particularly high. It is possible to reliably prevent the deformation.

By the way, in the case of providing the hitting material 9 as described above, the flat roof is formed on the setback space 1, and in the case of not providing the hitting material 9, above the setback space 1. A floor panel on the second floor is provided in the floor, and the floor panel is connected to the structural material on the first floor such as the outer wall panel 3 so that the horizontal rigidity of the floor panel can prevent out-of-plane force such as seismic force or wind pressure. It is supposed to be restrained. In the case where the flat roof is formed on the setback space 1 and the flat roof is a flat roof, in the case where the flat roof is formed by a substantially horizontal roof panel, the horizontal rigidity of the substantially horizontal roof panel is set. Therefore, the out-of-plane force such as seismic force or wind pressure can be restrained, and in this case, the hitting material 9 need not be provided.

The construction can be simplified, and even though the outer wall panel and the beam are divided so as to simplify the manufacturing, transportation, and construction, the end portion of the setback space of the outer wall panel on the inlet side. And the side edges of the setback outer wall panel that has retreated to the inside of the building to form a setback space are connected, and the setback outer wall panel is configured by attaching a structural face plate to the frame material. , Setback which is a structural panel in which structural faceplates are attached to the frame material even if an out-of-plane force such as seismic force or wind pressure is applied. The setback of the outer wall panel including the connection part between the outer wall panel and the beam by the outer wall panel The end portion of the space on the inlet side can be supported, and the deformation of this portion can be reliably prevented.

Further, the outer wall surface adjacent to the corner portion of the panel construction method at a right angle is retracted inward to form a setback space, which constitutes a non-retracted portion of the outer wall surface and the side end portion is setback. Since the upper ends of both outer wall panels located at the entrance-side end of the space and independent columns standing at the intersections of the extension lines of both outer wall panels are connected by beams, they are formed at the corners of the building. The entrance of the set-back space can be composed of an outer wall panel, a beam, and an independent column. As a result, the vertical wall panel is integrated with the panel main body laterally from the upper end of the side end of the conventional panel main body. It does not require an external wall panel for the setback entrance configuration that has a special shape and structure in which parts are arranged in series, and simplifies manufacturing, transportation, and construction, and in this way, simplifies manufacturing, transportation, and construction. The outer wall Despite being divided into a flannel and a beam, the other end of the setback outer wall panel that is receded to the inside of the building and connected orthogonally to each other to form an entry corner of the setback space, Each of the outer wall panels is connected to the inlet side end of the setback space, the setback outer wall panel is constructed by attaching a structural face plate to the frame material, and the upper ends of both setback outer wall panels are connected with a flint. Therefore, even if an out-of-plane force such as seismic force or wind pressure is applied, the set-back outer wall panel with the structural face plate attached to the frame material will prevent the set-back space of the outer wall panel including the connecting portion between the outer wall panel and the beam. The entrance side end can be supported, and it is possible to reliably prevent this part from deforming, and a truss structure is formed by both setback outer wall panels that are structural panels connected at a right angle and the hitting material. Out-of-plane direction Strength are those that can be improved.
