  Next, the operation of this embodiment will be described.

  In the case of a fire due to a fire from the room 24 side of the building unit 12, in the unit building 14, as shown in FIG. B is mentioned. The first path A is a path through which the inner plate 68 of the docking portion X of the column member 18 cracks and the temperature of the column member 18 rises or the inner plate 68 peels off, and the flame reaches the column member 18. As a result, the side surface 18C of the column member 18 on the indoor 24 side is directly struck by a flame and the temperature rises.

  Further, the second path B is a path through which the inner plate 68 adjacent to the docking portion X cracks, the temperature of the side surface of the column member 18 rises, or the inner plate 68 peels off, and the flame reaches the column member 18. With this, the side surface 18B of the column member 18 is directly struck by a flame and the temperature rises.

  For this reason, in the present embodiment, the first route and the second route are blocked.

(Blocking the first route)

  As shown in FIGS. 1 and 2, in the present embodiment, a fireproof board 60 is provided between the column member 18 and the inner plate 68 </ b> A on the indoor 24 side of the column member 18. The fireproof board 60 blocks heat transfer from the indoor 24 side to the column member 18 (including the case where heat transfer is suppressed).

  And the reinforced gypsum board is used for the inner board 68A. This reinforced gypsum board is a fireproof board containing glass fiber and has higher fire resistance than a normal fireproof board (described later). Therefore, only the portion of the inner plate 68 corresponding to the docking portion X of the outer plate 26, that is, the portion that can face the column member 18 is a reinforced plaster plate.

  Since the cost of the reinforced gypsum board is higher than that of a normal fireproof board, the fireproof performance of the building structure 10 can be improved at low cost by minimizing the use of this reinforced gypsum board. Moreover, since it is only necessary to employ the inner plate 68A having excellent fireproof and fireproof performance at the portion corresponding to the docking portion X of the outer plate 26, stable performance can be ensured without performing complicated work.

  Here, FIG. 5A shows a case where a general fireproof board (indicated by a dotted line) is used for the inner plate 68A by a method according to the heating temperature and measurement position in the combustion test of ISO834, and a reinforced gypsum plate. A change in temperature of the side surface 18C of the column member 18 (measured at a position 12 mm or 5 mm away from the side surface 18C of the column member 18) is shown when using (shown by a solid line).

  When the temperature of the column member 18 reaches 600 ° C., the building unit 12 is assumed to collapse. Therefore, here, as the time until the surface temperature of the column member 18 reaches about 500 ° C., the temperature change in 7 minutes is taken. It was measured.

  According to this, after about 3.5 minutes from the occurrence of the fire, the temperature difference gradually increases between the general fireproof board and the reinforced gypsum board. The temperature difference is about 80 ° C. Then, after 6 minutes have passed since the occurrence of the fire, the temperature difference further increases, and after 7 minutes, the temperature is about 130 ° C.

  That is, it can be seen that the fireproof performance is improved by using the reinforced gypsum board as compared with the case of using a general fireproof board for the inner plate 68.

  In the present embodiment, a reinforced gypsum plate is used as the inner plate 68A and the fireproof board 60 is provided between the inner plate 68A and the column member 18, but it is not always necessary to use both of them. For example, as shown in FIG. 6, in the state where the fireproof board 60 is provided between the inner plate 68A and the pillar member 18, the inner plate 68A may use the same fireproof board as the inner plate 68B.

  Further, a reinforced gypsum plate may be used for the inner plate 68A in a state where the fireproof board 60 (see FIG. 1) is not provided (space) between the inner plate 68A and the pillar member 18. That is, by applying either one of the specifications, the fire resistance performance of the building structure 10 is improved as compared with a case where at least nothing is applied.

(Blocking the second route)

  As shown in FIGS. 1 and 2, in this embodiment, the column member 18 is disposed between the vertical beam 52A for fixing the horizontal beam 52B of the outer wall frame 52 and the vertical beam 58A for fixing the horizontal beam 58B of the inner wall frame 58. A prismatic wooden member 56 extending over the entire region in the height direction is provided.

  Thereby, not only can the air permeability between the horizontal beam 52B of the outer wall frame 52 and the horizontal beam 58B of the inner wall frame 58 and the column member 18 be secured via the wooden member 56, but also the space 66 and the space 49 The building structure is closed by blocking the heat transmitted from the interior 24 side through the horizontal rail 58B of the inner wall frame 58 to the side surface 18B of the pillar member 18 (including the case where the heat transfer is suppressed). The fire resistance of 10 can be improved.

  Here, since the wooden member 56 that blocks the flame from the side surface of the column member 18 only needs to extend over the entire region in the height direction of the column member 18, an expensive fireproof and fireproof material is provided on the side surface 18B of the column member 18. Is unnecessary. Further, since the building unit 12 can be assembled in the assembly plant, stable performance can be ensured and quality control is easy.

  Furthermore, since it is only necessary to extend the wooden member 56 over the entire region of the column member 18 in the height direction, the workability is improved as compared with the case where the column member 18 is covered with a fireproof coating material. The structure of 18 can be simplified and workability improves.

  Here, in FIG. 5B, the vertical beam 52A for fixing the horizontal beam 52B of the outer wall frame 52 and the horizontal beam 58B of the inner wall frame 58 are fixed by a method according to the heating temperature and measurement position in the combustion test of ISO834. When the wood member 56 provided between the vertical bars 58A is intermittently arranged in the height direction of the column member 18 (indicated by a dotted line), it extends over the entire region in the height direction of the column member 18. In the case (shown by a solid line), the temperature change of the side surface 18B of the column member 18 (measured at a position 12 mm or 5 mm away from the side surface 18B of the column member 18) is shown.

  According to this, after about 3.5 minutes from the occurrence of the fire, the temperature difference gradually increases between the case where the wooden members are arranged intermittently and the case where they are continuously arranged, and 5 minutes have passed since the occurrence of the fire. Then, the temperature difference is about 80 ° C. The temperature difference gradually increases further, and after about 7 minutes, the temperature difference is about 300 ° C.

  That is, it can be seen that the fire resistance is improved when the wooden members 56 are continuously arranged as compared with the case where the wooden members are arranged intermittently.

  Although not shown, a fireproof film may be wound around the surface of the wooden member 56. Since the wooden member 56 has a higher surface friction coefficient than the surface of the column member 18 that is a steel material, it is easier to wind a fire-resistant film on the surface than the column member 18 and the operation is easy. Moreover, the fireproof performance of the building structure 10 can be improved by winding a fireproof film around the surface of the wooden member 56 and improving the fireproof performance of the wooden member 56.

  On the other hand, a long plate-like plywood 46 and a reinforced gypsum board 48 are provided on the side surface 18B of the column member 18 so as to cover the side surface 18B of the column member 18 in the entire height direction of the column member 18. Yes. Thereby, the heat transmitted to the side surface 18B of the column member 18 can be shut off. The reinforced gypsum board 48 is not necessarily provided.
