[0010] The following describes a building according to an embodiment of the present disclosure with reference to the drawings. The embodiment shows one aspect of the present disclosure, does not limit the present disclosure, and can be modified as desired within the scope of the technical concept of the present disclosure.

[0011] First Embodiment (composition) Fig. 1 is a diagram that schematically shows the configuration of a building 1 according to the first embodiment. As illustrated in Fig. 1, the building 1 includes a steel beam 2, a panel receiving member 4, and an NLT panel 6. Note that Fig. 1 shows a portion of the building 1 to explain the steel beam 2, the panel receiving member 4, and the NLT panel 6, but the building 1 also includes components other than those shown in Fig. 1 (for example, walls).

[0012] In the present disclosure, the horizontal direction perpendicular to the up-down direction D1 in which the steel beams 2 extend is referred to as the extension direction D2, and the horizontal direction perpendicular to the extension direction D2 is referred to as the left-right direction D3.

[0013] One end of the steel beam 2 is connected to a beam-column joint 3 and is joined to a column 5 via the beam-column joint 3. The steel beam 2 includes a steel frame 8 extending along the extension direction D2. In the embodiment illustrated in FIG. 1 , the steel frame 8 is an H-shaped steel including an upper flange 10, a lower flange 12 positioned below the upper flange 10, and a web 14 connecting the upper flange 10 and the lower flange 12. The steel beam 2 includes a first steel frame 8a (8), a second steel frame 8b (8) provided separately from the first steel frame 8a, and a joint portion 20 including a splice plate 22 for joining the first steel frame 8a and the second steel frame 8b. In the first embodiment, one end of the first steel frame 8a is joined to the beam-column joint 3 and the other end is joined to the second steel frame 8b. The beam-column joint 3 may have any configuration as long as it is configured to be able to join the steel beam 2 and the column 5. The first steel frame 8a and the second steel frame 8b may be joined to each other by a method other than the joint portion 20 including the splice plate 22, and may be joined to each other by, for example, welding.

[0014] The joint portion 20 will now be described. In the first embodiment, as illustrated in FIG. 1 , the upper flange 10 of the first steel frame 8a and the upper flange 10 of the second steel frame 8b are sandwiched between splice plates 22, 22 from both sides in the up-down direction D1. The upper flange 10 of the first steel frame 8a, the upper flange 10 of the second steel frame 8b, and the splice plates 22, 22 are fastened together with high-strength bolts 24, thereby joining the first steel frame 8a and the second steel frame 8b to each other. Hereinafter, the term "splice plate 22" refers to the upper splice plate 22. Note that the joint portion 20 may include splice plates that sandwich the lower flange 12 from both sides in the up-down direction D1, or splice plates that sandwich the web 14 from both sides in the left-right direction D3.

[0015] FIG. 2 is a diagram illustrating the configuration of the panel receiving member 4 according to the first embodiment, showing the panel receiving member 4 as viewed from the extension direction D2. As shown in FIG. 2, the panel receiving member 4 is joined to a side surface 7 of a steel beam 2. The panel receiving member 4 includes a receiving surface 9 facing upward. In the present disclosure, the side surface 7 of the steel beam 2 includes a side surface 7a of the upper flange 10, a side surface 7b of the lower flange 12, and a side surface 7c of the web 14. In the first embodiment, as illustrated in FIG. 2, the panel receiving member 4 is a plate 4A(4) having a plate shape. The plate 4A is made of metal and is welded to the side surface 7a (right side surface) of the upper flange 10 so that the receiving surface 9 and the upper surface 11 of the upper flange 10 are flush with each other. The plate 4A may be welded over the entire extension direction D2 of the side surface 7a of the upper flange 10, or may be welded to a portion of the extension direction D2 of the side surface 7a of the upper flange 10. In some embodiments, a plurality of plates 4A are welded to the side surface 7a of the upper flange 10 at intervals in the extension direction D2.

[0016] The NLT panel 6 will now be described. FIG. 3 is a diagram schematically illustrating the configuration of the NLT panel 6 according to the first embodiment. As illustrated in FIG. 3, the NLT panel 6 includes a plurality of long wooden pieces 30 and nails 32. The wooden pieces 30 are two-by-four lumber such as 2x4 lumber. Each of the wooden pieces 30 is end-standing and fastened with nails 32, and is stacked on top of each other along the short-side direction D4 of the wooden pieces 30 (NLT: Nail Laminated Timber). In the first embodiment, a flat floor surface 6a is formed by stacking the wooden pieces 30 on top of each other. Furthermore, the NLT panel 6 uses wooden pieces 30 of different lengths, thereby forming an avoidance space 13, which is a portion where the wooden pieces 30 are not stacked. The avoidance space 13 penetrates the NLT panel 6 in the vertical direction D1. The floor surface 6a may have any shape; for example, the floor surface 6a may have a curved shape or a stepped shape that protrudes upward. The avoidance space 13 may be located at the edge of the NLT panel 6 as shown in Fig. 3, or may be located in the center of the NLT panel 6. In the first embodiment, each of the plurality of wooden pieces 30 is fastened by a nail 32, but the present disclosure is not limited to this. For example, screws may be used instead of the nails 32.

[0017] The above-mentioned NLT panel 6 is placed on the receiving surface 9 of the plate 4A (panel receiving member 4), as exemplified in Fig. 2. In the first embodiment, the NLT panel 6 is placed across both the receiving surface 9 of the plate 4A and the upper surface 11 of the upper flange 10. The NLT panel 6 may extend to the left of the steel beam 2. In this case, although not shown, the building 1 may further include a second plate 4A welded to the left side of the upper flange 10 (the surface opposite the right side in the left-right direction).

[0018] In the first embodiment, as illustrated in FIG. 2, the building 1 further includes an NLT mounting screw 16 that penetrates the plate 4A from below and has an upper end 17 located inside the NLT panel 6.

[0019] In the first embodiment, as illustrated in each of Figures 1 and 2, the building 1 further includes a plate-shaped board 18 attached to the floor surface 6a (upper surface) of the NLT panel 6. The board 18 is formed of a core material harder than the wood 30, for example, reinforced gypsum board. Note that the present disclosure is not limited to the board 18 being formed of a core material harder than the wood 30. The board 18 may also be formed of a core material softer than the wood 30, as long as it is possible to make the floor surface 6a of the NLT panel 6 smooth.

[0020] FIG. 4 is a diagram for explaining the configuration of the NLT panel 6 according to the first embodiment, showing the NLT panel 6 as viewed from above. Note that the board 18 is omitted from FIG. 4. In the first embodiment, as illustrated in FIG. 4, the NLT panel 6 and the joint portion 20 are arranged so as not to overlap each other when viewed from above. Specifically, the splice plate 22 and high-strength bolts 24 of the joint portion 20 are located within the avoidance space 13 formed in the NLT panel 6. In other words, the NLT panel 6 is arranged so that the avoidance space 13 is located above the joint portion 20.

[0021] (Actions and Effects) The functions and effects of the building 1 according to the first embodiment will be described. According to the first embodiment, the NLT panel 6 is placed on the steel beam 2 via the plate 4A. Therefore, even if an interfering object such as a splice plate 22 or a high-strength bolt 24 is provided on the upper surface of the steel beam 2, the NLT panel 6 can be placed on the steel beam 2 while avoiding the interference of the interfering object. Furthermore, the NLT panel 6 is formed simply by stacking pieces of wood 30 on top of each other along the short-side direction D4, so no special equipment is required. This makes it possible to simplify the manufacture of the building 1.

[0022] According to the first embodiment, the receiving surface 9 of the plate 4A and the upper surface 11 of the upper flange 10 are flush with each other, so that the NLT panel 6 can be placed across both the receiving surface 9 of the plate 4A and the upper surface 11 of the upper flange 10.

[0023] According to the first embodiment, the NLT panel 6 is arranged so that the avoidance space 13 is located above the joint portion 20, so that the NLT panel 6 can be prevented from coming into contact with the splice plate 22 and the high-strength bolt 24.

[0024] In the first embodiment, the plate 4A is welded to the side surface 7a of the upper flange 10, but the present disclosure is not limited to this configuration. FIG. 5 is a diagram schematically illustrating the configuration of a plate 4A according to a modification of the first embodiment. In the configuration illustrated in FIG. 5, the plate 4A is welded to the side surface 7c of the web 14 of the steel frame 8 of the steel beam 2. The building 1 further includes a rib 19 that is joined below the web 14 and supports the plate 4A. This configuration allows the NLT panel 6 to be positioned below the top surface of the steel beam 2, making it possible to accommodate the formation of a step. Furthermore, because the plate 4A is supported by the rib 19, deformation due to the load from the NLT panel 6 is suppressed.

[0025] In the first embodiment, the plate 4A is applied to simplify the configuration of the panel receiving member 4, but the present disclosure is not limited to this form.

[0026] Second Embodiment A description will now be given of a building 1 according to a second embodiment of the present disclosure. In the building 1 according to the second embodiment, a member other than the plate 4A is applied to the panel receiving member 4. In the second embodiment, the same components as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted.

[0027] (composition) Fig. 6 is a diagram illustrating the configuration of a panel receiving member 4 according to the second embodiment. As illustrated in Fig. 6, the panel receiving member 4 is an L-shaped member 4B(4) having an L-shape when viewed from the extension direction D2. The L-shaped member 4B is a so-called angle iron and is made of metal.

[0028] The L-shaped member 4B includes an upper and lower extending portion 42 joined to the side surface 7 of the steel beam 2 and extending along the vertical direction D1, and a horizontal extending portion 44 including the receiving surface 9 and extending from the upper and lower extending portion 42 along a direction intersecting the vertical direction D1.

[0029] In the second embodiment, as illustrated in FIG. 6 , the vertical extension portion 42 is welded to the side surface 7a (right side surface) of the top flange 10. The upper end 43 of the vertical extension portion 42 is located higher than the top surface 11 of the top flange 10. The horizontal extension portion 44 extends from the upper end 43 of the vertical extension portion 42 so as to move away from the steel beam 2. Specifically, the horizontal extension portion 44 extends to the right from the upper end 43 of the vertical extension portion 42. The L-shaped member 4B may be welded over the entire extension direction D2 of the side surface 7a of the top flange 10, or may be welded to a portion of the extension direction D2 of the side surface 7a of the top flange 10. In some embodiments, a plurality of L-shaped members 4B are welded to the side surface 7a of the top flange 10.

[0030] In the second embodiment, as illustrated in Figure 6, the building 1 further includes an NLT mounting screw 16 that penetrates the horizontal extension portion 44 of the L-shaped member 4B from below and has an upper end 17 located inside the NLT panel 6.

[0031] (Actions and Effects) The following describes the action and effect of the building 1 according to the second embodiment. According to the second embodiment, the NLT panel 6 can be placed at any height by using the L-shaped member 4B as the panel receiving member 4. According to the second embodiment, the range of height positions at which the NLT panel 6 can be placed can be increased compared to when the plate 4A is used.

[0032] According to the second embodiment, the upper and lower extensions 42 are welded to the side surface 7a of the upper flange 10, which makes it easy to join the L-shaped member 4B to the steel beam 2. According to the second embodiment, the receiving surface 9 of the L-shaped member 4B is located above the upper surface 11 of the upper flange 10, so the NLT panel 6 can be placed above the upper flange 10. In this case, by placing the NLT panel 6 above the obstruction, it is not necessary to form an avoidance space 13 in the NLT panel 6.

[0033] In the second embodiment, the receiving surface 9 of the L-shaped member 4B is located above the upper surface 11 of the upper flange 10, but the present disclosure is not limited to this configuration. Fig. 7 is a diagram for explaining the configuration of the L-shaped member 4B according to a first modified example of the second embodiment. In the configuration illustrated in Fig. 7, the lower end 45 of the vertical extension portion 42 is located below the upper surface 11 of the upper flange 10. The horizontal extension portion 44 extends to the right from the lower end 45 of the vertical extension portion 42 so as to move away from the steel beam 2.

[0034] Although the horizontally extending portion 44 extends rightward from the upper end 43 of the vertically extending portion 42 in the second embodiment, the present disclosure is not limited to this configuration. FIG. 8 is a diagram illustrating the configuration of an L-shaped member 4B according to a second modified example of the second embodiment. In the configuration illustrated in FIG. 8, the horizontally extending portion 44 extends from the upper end 43 of the vertically extending portion 42 in the left-right direction D3 so as to approach the web 14. In other words, the receiving surface 9 of the L-shaped member 4B is located above the upper flange 10. The horizontally extending portion 44 has one end 49 opposite to the one end 48 connected to the upper end 43 of the vertically extending portion 42, and the other end 49 is located to the right of the web 14 in the left-right direction D3. FIG. 9 is a diagram illustrating the configuration of an L-shaped member 4B according to a third modified example of the second embodiment. In the configuration illustrated in FIG. 9, the other end 49 of the horizontally extending portion 44 is located to the left of the web 14 in the left-right direction D3. The other end 49 of the horizontally extending portion 44 may be located to the left of the left side surface of the upper flange 10 in the left-right direction D3.

[0035] Fig. 10 is a diagram illustrating the configuration of an L-shaped member 4B according to a fourth modified example of the second embodiment. In the example illustrated in Fig. 10, the portion of the vertical extension 42 between the upper end 43 and the lower end 45 in the vertical direction D1 is welded to the side surface 7a (right side surface) of the upper flange 10. In other words, the upper flange 10 is located between the upper end 43 and the lower end 45 of the vertical extension 42 in the vertical direction D1.

[0036] In the second embodiment, the vertical extensions 42 are welded to the side surface 7a of the upper flange 10, but the present disclosure is not limited to this configuration. Fig. 11 is a diagram illustrating the configuration of an L-shaped member 4B according to a fifth modified example of the second embodiment. In the configuration illustrated in Fig. 11, the vertical extensions 42 are welded to the side surface 7c (right side surface) of the web 14. Although not shown, in some embodiments, the vertical extensions 42 are welded to the side surface 7b of the lower flange 12.
