In the present embodiment, a multi-storey building adopts a configuration in which a veranda with a pillar is provided on the upper floor (for example, the second floor of a two-story building), and the roof of the building covers the top of the veranda. Is provided. The building is a unit type building constructed by a plurality of building units made of, for example, a steel frame.

  FIG. 1 is a perspective view of a veranda in a building as viewed obliquely from below, and FIG. 2 is a longitudinal sectional view showing a configuration of a roof portion of the veranda.

  As shown in FIG. 1, the building 10 has a first floor portion 11 as a lower floor portion and a second floor portion 12 as an upper floor portion, and a roof portion 13 is provided above the second floor portion 12. . The second floor portion 12 is provided with a veranda 15 so that a part of the outer wall 14 is recessed from the protruding corner of the first floor portion 11. That is, a corner is provided in the outer wall 14 of the second floor portion 12, and a veranda 15 is provided there. The veranda 15 is surrounded on both sides by the outer wall 14 and is open on both sides, and a waist wall portion 16 is provided on the open side. Further, the veranda 15 is provided with a veranda column 17 for supporting the roof portion 13 projecting above, and the protruding corner portion of the waist wall portion 16 is fixed to the veranda column 17.

  In the unit structure of the building 10, a veranda is formed above the building unit of the first floor portion 11 by placing the building unit of the second floor portion 12 backward (set back) with respect to the building unit of the first floor portion 11. Space is secured.

  A portion of the outer wall 14 that partitions the second-floor indoor space and the veranda space (a veranda outer wall 14a) is provided with a window 18 as an opening, and a sash door 19 as an opening / closing body is provided in the window 18. Yes. The window 18 is a sweep window, and a person can enter and exit the veranda 15 through the window 18.

  The roof portion 13 constitutes an inclined roof such as a dormitory roof or a gable roof. As shown in FIG. 2, the roof portion 13 is formed on a rafter 21 as a roof frame extending in the roof inclination direction, a field board 22 as a roof base material provided on the rafter 21, and the field board 22. The roof tiles 23 are provided as roof finishing materials. In the roof portion 13, a portion protruding from the outer wall 14 to the outdoor side is an eave portion 25, and a nose tip tree 26 is fixed to the tip portion of the rafter 21 in the eave portion 25. As shown in FIG. 1, the length from the outer wall surface to the eaves tip is different in the eaves portion 25 between the veranda 15 and the other portions, and the eave length is larger than the other portions in the veranda 15. Yes. In the eaves portion 25, a portion above the veranda 15 (a portion having a long eave length) is supported by the veranda pillar 17.

  In this embodiment, the eaves part 25 (especially the eaves part above a veranda) is equivalent to the incidental structure provided in the site | part adjacent to the outer wall surface overhanging from the outer wall surface.

  A plurality of eaves top members 27 constituting the eaves top part are provided at the lower part of the eaves part 25 (that is, the back of the eaves). The eaves top member 27 is made of a plate-like incombustible material having predetermined fire resistance, and is provided between the outer wall 14 and the nose tip tree 26.

  A shutter device 30 as equipment is provided above the window 18 in the outer wall 14a of the veranda. The shutter device 30 includes a shutter curtain 31 that moves up and down along the window 18 (the outdoor surface of the sash door), and a horizontally long shutter case 32 that houses the shutter curtain 31 in a wound state. The shutter curtain 31 is, for example, a slat type shutter curtain. Particularly in the present embodiment, the shutter case 32 is attached to the veranda outer wall 14 a so that a part of the shutter case 32 is embedded in the eaves portion 25, and only a part of the shutter case 32 is located below the eaves ceiling member 27. It is supposed to be exposed. In this case, in addition to enabling the shutter device 30 to be installed by effectively using the eave roof space above the eave roof material 27, it is possible to expect the effect that the window portion 18 can be expanded upward on the veranda outer wall 14a.

  It is also possible to provide the shutter case 32 so as to be embedded in the eaves part 25 as a whole. In this case, the height position of the lower surface of the eaves top member 27 and the height position of the lower surface of the shutter case 32 substantially coincide.

  The eaves part 40 is provided with an eaves frame 40 as a structural frame. Next, the structure of the eaves frame 40 will be described. FIG. 3 is a plan view showing the configuration of the eaves frame 40. In FIG. 3, HL indicates the outer edge of the building body, and RL indicates the outer edge of the roof portion 13.

  The eaves frame 40 is provided at a position above the eaves ceiling material 27 so as to extend in the horizontal direction (see FIG. 2). The eaves frame 40 has one end fixed to a building body column (a column of a building unit or a ceiling beam), and extends from the outer wall surface (the outer surface of the veranda outer wall 14a provided with the window 18) in a direction perpendicular thereto. A pair of projecting beams 41 and a pair of connecting beams 42 extending in a direction perpendicular to the projecting beams 41, that is, in a direction horizontal to the outer wall surface and coupled to the tip portion and the middle portion of the projecting beam 41, respectively. Have. Each connecting beam 42 is provided at a position separated from the outer wall surface. The overhanging beam 41 and the connecting beam 42 are each made of channel steel having a U-shaped cross section. The overhanging beams 41 are provided in such a direction that the groove openings are on the center side of the frame, and the connecting beams 42 are provided so that the groove openings face each other. For convenience of explanation, the connecting beam 42 connected to the tip portion of the overhanging beam 41 is also referred to as “tip connecting beam 42a”, and the connecting beam 42 connected to the intermediate portion is also referred to as “intermediate connecting beam 42b”.

  Specifically, for example, a fixing bracket is attached to a column of a building unit by welding or the like, and the protruding beam 41 is fixed to the fixing bracket by a bolt or the like. One end of the veranda 15 on the protruding corner side is supported by the veranda pillar 17 and the other end opposite to the end connecting beam 42a is connected to the building body.

  A plurality of small beams 43 are provided between the pair of connecting beams 42 in a direction parallel to the protruding beam 41. The small beam 43 is made of a steel material having a smaller cross-sectional dimension than the overhanging beam 41 and the connecting beam 42, and is, for example, a grooved steel or a square steel. The small beam 43 is a member for fixing a support member for supporting the eaves ceiling material 27 by suspending it. Further, an intermediate beam 44 is provided between the pair of connecting beams 42 at the center in the longitudinal direction of the connecting beam 42.

  As shown in FIG. 2, a suspension support member 45 extending downward is fixed to the beam 43, and a base material 46 of the eaves ceiling member 27 is fixed to the lower end of the suspension support member 45. The base material 46 is made of a long material extending in the same direction as the eaves edge, and the eave ceiling material 27 is suspended and supported by a suspension support material 45 at a portion below the eaves frame 40. Further, in a portion other than the lower side of the eaves frame 40, the base material 46 is fixed to a suspension support material 47 that extends downward from the rafter 21 and is different from the suspension support material 45. A top member 27 is supported by being suspended.

  Moreover, in the eaves part 25, it is desirable to employ a reinforcing structure in order to increase the horizontal resistance force in the eaves part 25. However, in the configuration in which the shutter device 30 (shutter case 32) is attached to the eave portion 25 so as to be partially embedded as described above, there is a concern that the shutter device 30 and the reinforcing structure interfere with each other. That is, as shown in FIG. 2, the eaves frame 40 and the shutter device 30 are arranged side by side in the horizontal direction. For example, when a reinforcing structure is provided on the entire eave frame 40, the reinforcing structure is used as the shutter device. 30.

  Therefore, in this embodiment, the eaves frame 40 is provided with a reinforcing structure at a position where it does not interfere with the shutter device 30, that is, at a position separated from the veranda outer wall 14 a to which the shutter device 30 is attached by a predetermined distance or more. In this embodiment, a brace structure is adopted as the reinforcing structure.

  Specifically, as shown in FIG. 3, the width dimension in the front-rear direction of the shutter device 30 is W, and the intermediate connecting beam 42 b of the eave frame 40 is larger than the width dimension W of the shutter device 30 from the veranda outer wall 14 a. It arrange | positions in the position which separated the distance L1. Thereby, the shutter installation space S is ensured between the veranda outer wall 14a and the intermediate connection beam 42b. The shutter installation space is not provided with a reinforcing structure, and a brace reinforcing portion 50 as a reinforcing structure is provided on the distal end side (eave side).

  FIG. 4 is a view showing an outline of the brace reinforcing portion 50. In FIG. 4, the small beam 43 is omitted.

  In FIG. 4, the eaves frame 40 is provided with two sets of brace reinforcing portions 50 sandwiching the intermediate beam 44 at a position between the connecting beams 42. In this case, the two sets of brace reinforcing portions 50 are provided side by side in a direction parallel to the outer wall surface (the outer surface of the veranda outer wall 14 a provided with the window 18), that is, in the longitudinal direction of the eave frame 40.

  For details of the brace reinforcing portion 50, brackets 51 as brace mounting brackets are fixed to the connecting portion between the overhanging beam 41 and the connecting beam 42, and the connecting portion between the connecting beam 42 and the intermediate beam 44, respectively. The brace 52 is arranged in an X shape on the bracket 51. The brace 52 is fixed to the bracket 51 by bolt joining. In this configuration, the horizontal structural surface transmission force in the eaves portion 25 is ensured by the braces 52 in the eaves frame 40. The brace 52 is attached with a turnbuckle (not shown) as an adjustment mechanism for adjusting the tension.

  Each brace 52 is attached such that an angle (brace inclination angle θ) with respect to a direction extending parallel to the outer wall surface is smaller than 45 degrees. However, the eaves frame 40 is divided into two regions between the left and right overhanging beams 41 and each region is provided with a brace reinforcing portion 50. Therefore, only one brace reinforcing portion 50 is provided. The brace inclination angle θ is larger than that in the case (when not divided).

  The case where horizontal stress acts on the building 10 will be described with reference to FIG. FIG. 5 schematically shows a state in which horizontal stress P acts on the building 10 in a direction extending parallel to the outer wall surface, and the eaves portion 25 is displaced in the horizontal direction.

  Here, in the eaves frame 40, since two sets of brace reinforcing portions 50 are provided side by side between the left and right overhanging beams 41 in the longitudinal direction of the eaves frame 40, when the illustrated horizontal stress P acts, Axial force F (tensile stress) acting on each brace reinforcement 50 is dispersed in a plurality. That is, as compared with a configuration in which the single brace reinforcing portion 50 is provided between the left and right overhanging beams 41 in the eave frame 40, the brace burden load per one is reduced. Thereby, efficient stress transmission can be realized in the eaves frame 40, and the displacement amount δ (displacement angle) in the horizontal direction is reduced.

  Moreover, since the angle (brace inclination angle θ) formed between the direction parallel to the outer wall surface and each brace 52 is smaller than 45 degrees, in other words, the inclination of the brace 52 with respect to the outer wall surface is small. Therefore, compared to the case where the brace inclination angle θ is 45 degrees or more and the inclination of the brace 52 with respect to the outer wall surface is large, the structure is advantageous when the horizontal stress P in the direction parallel to the outer wall surface is applied.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the eave frame 40 of the eave portion 25 extending from the outer wall surface in the building 10 includes the brace reinforcing portion 50, the horizontal resistance force (surface rigidity) of the eave frame 40 is increased. Therefore, the structural strength of the eaves part 25 as an incidental structure can be increased. Moreover, since the brace reinforcement part 50 is provided in the position away from the outer wall surface, the empty space (shutter installation space S) in which the brace reinforcement part 50 is not provided in the edge part of the outer wall surface side in the eaves part 25 is provided. ) Is secured. Accordingly, the shutter device 30 can be provided at the same height as the eave frame 40 along the outer wall surface. As a result, it is possible to reduce restrictions on the degree of freedom of use for the eaves portion 25 protruding from the outer wall surface.

  The shutter device 30 is attached at the same height as the eaves frame 40 so as to be partially embedded in the eaves portion 25. Thereby, even if a dead space exists in the eaves part 25, the shutter device 30 can be attached by making good use of the dead space. In this case, as described above, in the eaves frame 40, since the brace reinforcing portion 50 is provided at a position separated from the outer wall surface, there is no restriction on the mounting of the shutter device 30, and the shutter device after effectively utilizing the space. 30 attachments can be realized.

  Moreover, it becomes possible to expand the window part 18 as much as possible in the veranda outer wall 14a. In this case, it is possible to increase the size of the window 18 on the veranda outer wall 14a while increasing the structural strength of the eaves 25.

  The angle (brace inclination angle θ) formed between the direction extending parallel to the outer wall surface and the brace 52 was made smaller than 45 degrees. Thereby, when the stress of the direction (direction along an eaves edge) parallel to an outer wall surface acts with respect to the eaves part 25, stress can be transmitted efficiently. This can be said to be a suitable configuration for protecting the eaves portion 25 that is a protruding structure.

  A plurality of brace reinforcing portions 50 are provided side by side in a direction parallel to the outer wall surface. Thereby, efficient stress transmission can be realized in the eaves frame 40, and the amount of displacement (displacement angle) in the horizontal direction can be reduced. By realizing efficient stress transmission in this manner, sufficient surface rigidity of the eaves frame 40 can be realized even if the brace reinforcing portion 50 is configured using a wire material having a relatively small diameter.
