BACKGROUND OF THE INVENTION In recent years, in the Building Standards Law, fireproof and fireproof performance grades such as fireproof buildings and semi-fireproof buildings have been set for buildings, and the buildings can be constructed according to the use, number of floors, scale and location of the building. It defines the range. Along with this, the fire-related regulations for wooden buildings have been greatly streamlined. For example, a structure other than a fireproof structure including a wooden structure and having fireproof performance similar to that of a fireproof structure has been newly positioned as a quasifireproof structure. The fire resistance performance of this quasi-fire resistant structure is the ability to withstand heating during a normal fire for a certain period of time, depending on the type of building part. Designate a structure recognized as having that performance as a quasi-fire resistant structure. I am trying.

Walls, columns, floors, beams, roofs, etc. are included in the types of building parts to be made into this semi-fireproof structure. Among them, the wall includes not only an outer wall and a partition wall, but also a doorway wall for separating adjacent dwelling units such as an apartment house. Therefore, as a matter of course, such a doorway wall is also required to have a sufficient fireproof structure.

FIG. 4 shows a conventional example in which a continuous wall between dwelling units such as an apartment house is constructed using outer wall panels. The doorway wall K shown in the figure is a double wall in which the outer wall panels P1 and P2 of the adjacent dwelling units A and B overlap each other, and is a structural example in which a gypsum board for fire protection is placed on the wall center side. That is, here, the outer wall panel P of the adjacent dwelling units A and B
As 1, P2, a structure having a pair of face materials (gypsum board) 2, 3 arranged in parallel with each other on both sides of the frame body 1 surrounding the periphery is used, and a little between the outer wall panels P1, P2. This is a so-called double-boundary wall structure in which both are overlapped with each other with a gap α.

By the way, it is required that the doorway wall that separates the adjacent dwelling units has a structure having sufficient sound insulation performance in addition to the required fire resistance performance. On the other hand, when the space α is formed between the outer wall panels P1 and P2, the transmission of sound between the outer wall panels P1 and P2 is reduced by the existence of the air layer due to the space α, and a good sound insulation effect is exhibited. However, on the other hand, there is a problem that the heat insulating property is poor because no heat insulating material is arranged in each of the outer wall panels P1 and P2.

Therefore, as shown in FIG. 5, heat insulating materials 4 and 5 are arranged between the vertical core members of the outer wall panels P1 and P2, respectively, and a gypsum board on the wall center side is not provided instead. It is also possible. By doing so, it is possible to enhance the heat insulating property of the doorway wall portion and at the same time eliminate the construction work and material cost of the gypsum board to be inserted into the wall center side. However, in such a structure, the vertical core member 6 on the outer wall panel P1 side and the vertical core member 7 on the outer wall panel P2 side face each other, and this causes an unfavorable problem from the viewpoint of the fire prevention structure. This is because if the longitudinal core members are close to each other in a form of facing each other, a problem of fire spread will occur between them.
From the viewpoint of eliminating the problem of the fire spread, it is sufficient to provide the gypsum board 2 on the wall core side in addition to the heat insulating material, but then the amount of material used becomes unnecessarily large and the design is excessive. Therefore, it is not a good solution because the construction cost increases accordingly.

According to the present invention, in a building including a plurality of independent dwelling units, a doorway wall located at a boundary between a first dwelling unit and a second dwelling unit adjacent to each other is defined as Applies to buildings with a double-boundary wall structure by the outer wall panels of the first and second dwelling units. That is, each outer wall panel includes a frame body surrounding the periphery, a plurality of vertical core members arranged in parallel with each other in the frame body, a heat insulating material arranged between the vertical core members, and the frame. With respect to the body, a face material made of a fireproof board provided on the indoor side surface of the dwelling unit. Then, the vertical core members of the outer wall panel of the first dwelling unit and the vertical core members of the outer wall panel of the second dwelling unit are set to have a staggered arrangement relationship with each other. Since there is a heat insulating material between the vertical core materials of each outer wall panel and a fire resistant board on the indoor side, the fire resistant performance required for a doorway wall can be obtained. In that case, since the vertical core members of the outer wall panel of the first dwelling unit and the vertical core members of the outer wall panel of the second dwelling unit have a staggered arrangement relationship with each other,
The vertical core members do not face each other between the outer wall panels, and the vertical core members are sufficiently separated from each other. Therefore, the problem of fire spread due to the vertical core members facing each other facing each other can be basically eliminated.

Here, the gap between the outer wall panel of the first dwelling unit and the outer wall panel of the second dwelling unit in the portion forming the double boundary wall does not necessarily need to be provided, but sound insulation is required. It is desirable to provide this in order to improve the property. However, it is better to set the size of the gap smaller. This is because the thickness of the doorway wall can be reduced accordingly. Moreover, since the vertical core members are arranged in a staggered arrangement, the distance between the vertical core members is hardly influenced by the size of the gap. As for the fireproof board, it is preferable to use a double-laid gypsum board in consideration of the improvement of the fireproof performance of the boundary wall, the construction cost and the material cost.

Further, according to the present invention, as a panel for constituting a doorway wall, a frame surrounding the periphery thereof, a pair of face members arranged in parallel to each other on both sides of the frame, and inside the frame, Including a plurality of vertical core members arranged in parallel at intervals, each of the vertical core members, one of the pair of face members is fixed to one face member side, the other surface is the other face member A first vertical core group composed of a plurality of vertical cores separated from each other, and a first vertical core group having one surface fixed to the other surface side and the other surface formed of a plurality of vertical cores separated from the one surface material. It is configured to include two vertical core members. Then, the vertical core members of the first vertical core member group and the vertical core members of the second vertical core member group are arranged in a zigzag relationship with each other, and furthermore, a heat insulating member is arranged between the vertical core members. . When the panel for a doorway wall having such a configuration is used, the doorway wall itself can be configured as a single wall. Therefore, there is an advantage that it can be made thinner than in the case of the double boundary wall structure. Moreover, since the vertical core members are arranged in a staggered arrangement, it is possible to secure the spread-fire prevention effect and the necessary sound insulation effect together.

Here, the face material may have a structure in which a fire resistant board is directly attached instead of a plywood which is normally used. By doing so, panel manufacturability and material costs can be reduced. As a fireproof board,
From the standpoint of ensuring sufficient fire resistance, it is preferable to double-use gypsum board, which is more excellent in terms of reliability and material cost. In addition, the thickness (width) between the one surface and the other surface of each vertical core member is 1/2 of the distance between the pair of surface materials.
The above is preferable. If it is ½ or less, the strength of the vertical core material is lowered, and further, the strength of the entire panel is lowered, which is not preferable.

Further, the outer wall panel P of the first dwelling unit A.
The vertical core members 11 of No. 1 and the vertical core members 21 of the outer wall panel P2 of the second dwelling unit B are set to have a staggered arrangement relationship with each other. Although various methods can be considered for the staggered arrangement relationship, the number of the vertical core members 11 of the outer wall panel P1 and the number of the vertical core members 21 of the outer wall panel P2 are different here. In the embodiment, three vertical core members 11 of the outer wall panel P1 are arranged at equal intervals, and four vertical core members 21 of the outer wall panel P2 are arranged. Therefore, the outer wall panels P1 and P2 are composed of two types of outer wall panels having different numbers and arrangement relationships of the vertical core members 11 and 21, respectively. The outer wall panels P1 and P2 are basically the same except for the vertical core member.

The frame members 10 and 20 and the vertical core members 11 and 21 are made of wood. The frame bodies 10 and 20 are formed by assembling wooden square members into a rectangular frame shape, and are portions that surround the entire circumference of the outer wall panels P1 and P2. Further, rock wool or glass wool having a thickness of 50 mm is used for the heat insulating materials 12 and 22. Regarding the face materials 13 and 23,
Here, two plaster boards 13a, 13b and 23a, 23b each having a thickness of 12 mm are superposed on one surface side of the frame body 10, 20, that is, on the surface located on the indoor side of each dwelling unit A, B. It is stuck. The gypsum boards 13a and 13b are for enhancing the fireproof performance on the indoor side. Of the plaster boards, the plaster boards 13b and 23b on the front side are of course the outer wall panel P.
After the P1 and P2 are built in the predetermined position, they may be provided by the field work.

In a building including such a double-boundary wall portion, the fireproof boards 13 and 23 provided on the indoor side of each adjacent dwelling unit, and the heat insulating material 12 arranged in each outer wall panel P1 and P2, 22 and the action of the air layer due to the presence of the gap α provide the required fire resistance performance. In that case, in particular, since the vertical core members 11 on the outer wall panel P1 side and the vertical core members 21 on the outer wall panel P2 side have a staggered arrangement relationship, the vertical core members 11, 21 facing each other approach each other. Without doing so, it becomes a form in which they are sufficiently spaced apart from each other, and therefore the problem of fire spread through the vertical core can be fundamentally solved. In addition, such a staggered arrangement makes it possible to make the outer wall bending P1 and P2 sufficiently close to each other to further reduce the gap α. Thereby, the double boundary wall T can be thinned, and the occupied area of the dwelling units A and B can be expanded correspondingly.

When the panel for a doorway wall having such a configuration is used, the doorway wall itself can be configured as a single wall. Therefore, there is an advantage that it can be made thinner than in the case of the double boundary wall structure. Moreover, since the vertical core members 33 and 34 are arranged in a staggered manner, it is possible to secure the spread of fire prevention effect and the necessary sound insulation effect. In particular, since each of the vertical core members 33, 34 has a structure surrounded by a fireproof board and a heat insulating material, it has a convenient form in terms of fireproof performance.
