Description

Bridge components and buildings

[0001] The present disclosure relates to a bridging member and a building.

[0002] A building with a loggia is known (for example, see Patent Document 1). The building in Patent Document 1 includes a building body, a loggia wall provided at a position separated from the building body, and an extension of a beam material connecting the building body and the loggia wall.

[0003] Japanese Patent Application Laid-Open No. 2023-015532

[0004] Incidentally, the bridging member spanning two walls may be made of steel material with a flange. The end of the bridging member is connected to the skeleton inside the wall. In this case, the flange interferes with the exterior wall panel covering the skeleton. For this reason, the exterior wall panel must be processed so that it does not interfere with the flange. However, processing the exterior wall panel in this way takes time and effort.

[0005] (1) A bridging member according to one aspect of the present disclosure is a bridging member that is bridged between a first wall and a second wall, and includes a web, a flange provided on at least one of the upper and lower ends of the web, and a connecting plate that is provided on at least one of both ends of the web so as to intersect with the web and is connected to the main body of the first wall or the main body of the second wall, and the flange has a notch that extends a predetermined length from the end of the web.

[0006] According to this configuration, the provision of the notch in the flange of the bridging member simplifies the structure of the end of the bridging member. This reduces interference between the exterior wall panel covering the frame and the flange of the bridging member at the connection portion of the bridging member in the first or second wall. This allows for more efficient installation of the exterior wall panel in the connection portion of the bridging member in the first or second wall.

[0007] (2) In the bridging member of (1) above, the web and the flange are painted. This configuration can suppress deterioration of the bridging member due to water. (3) A building according to one aspect of the present disclosure includes a first building having the first wall, a second building having the second wall, and the bridging member of (1) or (2) above, and the bridging member is bridged between the first wall and the second wall.

[0008] According to this configuration, since the flange has a notch, there is no need to process the exterior wall panel for the flange. This makes it possible to improve the efficiency of construction of buildings. (4) In the building of (3) above, the first building and the second building comprise a skeleton and an exterior wall panel covering the skeleton, the connecting plate of the bridging member is connected to the skeleton, and the exterior wall panel is attached to the skeleton so that a portion of the exterior wall panel is located within the notch.

[0009] According to this configuration, the exterior wall panel adjacent to the bridging member is positioned near the web. This improves the aesthetic appearance of the area around the bridging member in the exterior wall. (5) In the building described in (4) above, a gap is provided between the flange of the bridging member and the exterior wall panel. According to this configuration, the exterior wall panel can be easily attached. Also, rainwater falling on the bridging member can be prevented from flowing to the exterior wall.

[0010] (6) In any one of the buildings described in (3) to (5) above, the bridging member is exposed. This configuration allows the height and width dimensions to be smaller than when the bridging member is covered with an exterior member. Furthermore, because the bridging member is simple, the space spanned by the bridging member can be made appear larger. Furthermore, the opening near the bridging member can be enlarged in the exterior wall to which the bridging member is connected.

[0011] (7) In any one of the buildings (3) to (6) above, the first building is a building body having rooms or a loggia wall, and the second building is a building body having rooms or a loggia wall. With this configuration, the building bodies having rooms can be connected to each other via a bridging member, thereby improving the strength of the building. Furthermore, the loggia walls can be connected to each other via a bridging member, thereby improving the strength of the building. Furthermore, the building having rooms and the loggia wall can be connected to each other via a bridging member, thereby improving the strength of the building.

[0012] (8) In the building of any one of (3) to (6) above, the second building is a main building having a room or a loggia wall, and the second building is a part of the first building. With this configuration, the building can be reinforced by the bridging member.

[0013] According to the bridging member and building of the present disclosure, the construction of exterior wall panels can be made more efficient for the exterior wall panels in the portion of the wall where the bridging member is connected.

[0015] The building 1 and bridging member 20 of this embodiment will be described with reference to Figures 1 to 7. Figure 1 is a cross-sectional view of the building 1 taken along a plane that is parallel to the bridging member 20 and extends in the vertical direction.

[0016] The building 1 includes a first building 3, a second building 4, and a bridging member 20. The bridging member 20 spans between a first wall 5 of the first building 3 and a second wall 6 of the second building 4. In this embodiment, the building 1 refers to the entire set of multiple buildings connected to each other by the bridging member 20. The building 1 has a loggia space SL. The loggia space SL is provided between the first building 3 and the second building 4. The loggia space SL may be provided between a portion of the first building 3 and the second building 4. The loggia space SL may be provided between a portion of the first building 3 and a portion of the second building 4. Specifically, the loggia space SL is provided between the first wall 5 of the first building 3 and the second wall 6 of the second building 4. The bridging member 20 is bridged between the first wall 5 and the second wall 6 so as to pass through the loggia space SL. By connecting the first wall 5 of the first building 3 to the second wall 6 of the second building 4 via the bridging member 20, the building 1 becomes strong as a whole. In this specification, the loggia space SL may refer to, for example, a semi-outdoor space. In one example, it refers to a space enclosed in a box shape by exterior wall materials. However, it is not limited to this.

[0017] The first building 3 is a building main body 7 or a loggia wall 8 having a room R. The first building 3 comprises a skeleton 10 and an exterior wall panel 11 covering the skeleton 10. The second building 4 is a building main body 7 or a loggia wall 8 having a room R. The second building 4 comprises a skeleton 14 and an exterior wall panel 15 covering the skeleton 14.

[0018] As shown in FIG. 1 , in this embodiment, the first building 3 is a building main body 7 having a room R. The building main body 7 is a two-story house 7A. Other examples of the first building 3 include public facilities, community centers, hospitals, and stores. The first building 3 has a skeleton 10 made of steel material 10A. Exterior wall panels 11 are attached to the skeleton 10 with metal fittings. The first building 3 has a first wall 5. The first wall 5 forms part of an exterior wall 7B of the house 7A.

[0019] In this embodiment, the second building 4 is a loggia wall 8. The loggia wall 8 is located a predetermined distance away from the residence 7A. The loggia wall 8 is erected parallel to the first wall 5 of the exterior walls 7B of the residence 7A. The loggia wall 8 has a framework 14 made of steel material 14A. Exterior wall panels 15 are attached to the framework 14 with metal fittings. The loggia wall 8 has a second wall 6. The second wall 6 forms part of the loggia wall 8.

[0020] 2 and 3, the bridging member 20 is connected to the portion of the house 7A between the first and second floors. The bridging member 20 is perpendicular to the exterior wall 7B and the loggia wall 8. In one example, the bridging member 20 is located on the exterior wall 7B of the house 7A at a position higher than the first floor sash 7C and lower than the second floor sash 7D. Note that in some countries, such as the United Kingdom and Australia, the "first floor" in this specification can be interpreted as the "ground floor" and the "second floor" can be interpreted as the "first floor," as appropriate.

[0021] The bridging member 20 has a first end 20X, which is one end in the longitudinal direction, and a second end 20Y, which is the end opposite to the first end 20X. In this embodiment, the first end 20X is a portion connected to the skeleton 10 of the first building 3.

[0022] 4, the bridging member 20 includes a web 21, a flange 22, and a connecting plate 23. The flange 22 is provided on at least one of the upper and lower ends of the web 21. In this embodiment, the flange 22 is provided on each of the upper and lower ends of the web 21.

[0023] The connection plate 23 is provided on at least one of both ends of the web 21 so as to intersect with the web 21. The connection plate 23 is connected to the skeleton 10 of the first wall 5 or the skeleton 14 of the second wall 6. The skeleton 10 of the first wall 5 is part of the skeleton 10 of the first building 3. The skeleton 14 of the second wall 6 is part of the skeleton 14 of the second building 4. In this embodiment, a connection plate 23 is provided on each end of the web 21 in the longitudinal direction.

[0024] The connection plate 23 includes a first portion 23A that protrudes in the width direction DX from a first surface 21A of the web 21 with respect to the web 21, and a second portion 23B that protrudes in the width direction DX from a second surface 21B opposite the first surface 21A of the web 21. Bolt holes 23C for inserting bolts are provided in the first portion 23A and the second portion 23B. The connection plate 23 is configured flat so that it can come into contact with the web 10B of the steel material 10A of the skeleton 10.

[0025] A first end 20X of the bridging member 20 is connected to the skeleton 10 of the first wall 5 via a connecting plate 23. The connecting plate 23 provided at the first end 20X is connected to the skeleton 10 with bolts and nuts. A second end 20Y of the bridging member 20 is connected to the skeleton 14 of the second wall 6 via the connecting plate 23. The connecting plate 23 provided at the second end 20Y is connected to the skeleton 14 with bolts and nuts.

[0026] As shown in Figure 4, the flange 22 has a first flange portion 22A protruding in the width direction DX from the first surface 21A of the web 21 and a second flange portion 22B protruding in the width direction DX from the second surface 21B of the web 21.

[0027] The flanges 22 are provided with cutouts 25. The cutouts 25 are formed so as to extend a predetermined length from the ends of the web 21 in the longitudinal direction of the bridging member 20. The predetermined length is greater than the thickness of the exterior wall panel 11. In this embodiment, the cutouts 25 are provided at both ends of the upper flange 22 and both ends of the lower flange 22 in the longitudinal direction. Specifically, the cutouts 25 are provided in the upper flange 22 so that both ends in the longitudinal direction are cut away. The cutouts 25 are provided in the lower flange 22 so that both ends in the longitudinal direction are cut away. By providing such cutouts 25, the bridging member 20 has plate-like portions 26 extending in the up-down direction near the first end 20X and the second end 20Y. The plate-like portions 26 do not have flanges 22.

[0028] The bridging member 20 is made of steel material 20A. In one example, the bridging member 20 is made of an H-shaped steel or an I-shaped steel. The bridging member 20 may also be made of two C-shaped steels. In this case, the webs 21 of the two C-shaped steels are joined together.

[0029] The connecting plate 23 is made of a steel plate. The connecting plate 23 is connected to the web 21 by welding. The connecting plate 23 may be joined to the web 21 by angle fittings and fastening members.

[0030] The web 21 and the flange 22 are painted. Preferably, the web 21, the flange 22, and the connecting plate 23 are painted. In one example, the web 21, the flange 22, and the connecting plate 23 are surface-treated by hot-dip galvanizing coating and fluorine baking coating. The fluorine baking coating is performed after the hot-dip galvanizing coating.

[0031] 1 , the first end 20X of the bridging member 20 is connected to the skeleton 10 of the first building 3. The second end 20Y of the bridging member 20 is connected to the skeleton 14 of the second building 4. The structure of the vicinity of the connection portion of the second end 20Y of the bridging member 20 is similar to the structure of the vicinity of the connection portion of the first end 20X of the bridging member 20. The connection structure of the first end 20X of the bridging member 20 will be described below.

[0032] 5 and 6, the bridging member 20 is connected perpendicularly to the steel members 10A of the skeleton 10. The bridging member 20 may be connected to the steel members 10A as beams or to the steel members 10A as columns.

[0033] The connection plate 23 comes into contact with the web 10B of the steel material 10A of the skeleton 10. The connection plate 23 is connected to the web 10B of the steel material 10A with bolts and nuts. When the bridging member 20 is connected to the skeleton 10, the cutout 25 is located at the same position as the exterior wall panel 11 in the direction perpendicular to the exterior wall 7B (hereinafter referred to as the exterior wall vertical direction DV). In other words, the plate-like portion 26 of the bridging member 20 is located at the same position as the exterior wall panel 11 of the first building 3 in the exterior wall vertical direction DV. The exterior wall panel 11 is attached to the skeleton 10 so that a portion of the exterior wall panel 11 is located within the cutout 25.

[0034] As shown in Figure 7, two exterior wall panels 11 arranged to sandwich the plate-shaped portion 26 of the bridging member 20 are provided with panel cutout portions 12 to avoid the plate-shaped portion 26. The plate-shaped portion 26 of the bridging member 20 is arranged between the panel cutout portions 12 of the two exterior wall panels 11.

[0035] The gap between the plate-shaped portion 26 of the bridging member 20 and the end face of the exterior wall panel 11 is sealed with the sealant 16. In addition, the gap between the end faces of the exterior wall panels 11 is sealed with the sealant 16.

[0036] 5 , when the bridging member 20 is connected to the steel material 10A of the skeleton 10 and the exterior wall panel 11 is attached to the skeleton 10, a gap S is provided between the flange 22 of the bridging member 20 and the exterior wall panel 11 in the exterior wall vertical direction DV. The gap S is set to a length equal to or greater than a first predetermined distance to ensure ease of attachment of the exterior wall panel 11. The gap S may also be set to a length equal to or greater than a second predetermined distance to prevent rainwater from the bridging member 20 from flowing onto the exterior wall 7B.

[0037] The bridging member 20 is exposed. In other words, the bridging member 20 is not covered by a wall material. Since the bridging member 20 is essentially composed only of steel material 20A, it appears slimmer than a bridging portion covered by a wall material. Because the bridging member 20 is slim, the opening provided in the exterior wall 7B to which the bridging member 20 is connected in the first building 3 can be made larger than a bridging portion covered by a wall material. Specifically, the sash 7C or sash 7D can be made larger.

[0038] [Operation of the Present Embodiment] When a component with a complex cross-sectional structure, such as an H-shaped steel beam, is used as the bridging member 20 in an exposed state, the processing of the exterior wall panel 11 becomes complicated at the portion where the bridging member 20 connects to the exterior wall 7B. For example, when an H-shaped steel beam is placed between two exterior wall panels 11, it is necessary to form a notch groove in the exterior wall panel 11 to accommodate the flange 22. The process of forming such a notch requires time and effort. Furthermore, the strength of the exterior wall panel 11 is reduced and the aesthetic appeal is impaired. In contrast, in the present embodiment, the flange 22 is provided with a notch 25 extending a predetermined length from the end of the web 21. This reduces the processing of the exterior wall panel 11. Specifically, it is not necessary to form a notch groove in the exterior wall panel 11 to accommodate the flange 22. Therefore, the bridging member 20 improves the efficiency of construction of the wall to which the bridging member 20 is connected.

[0039] [Advantages of this embodiment] The advantages of this embodiment will be described below. (1) The bridging member 20 includes a web 21, a flange 22, and a connection plate 23 connected to the skeleton 10 of the first wall 5. The flange 22 is provided with a notch 25 extending a predetermined length from the end of the web 21.

[0040] According to this configuration, the provision of the notch 25 in the flange 22 of the bridging member 20 simplifies the structure of the end of the bridging member 20. This reduces interference between the exterior wall panel 11 and the flange 22 of the bridging member 20 at the connection portion of the bridging member 20 in the first wall 5. This improves the efficiency of installation of the exterior wall panel 11 at the portion of the first wall 5 or the second wall 6 where the bridging member 20 is connected.

[0041] (2) The web 21 and the flange 22 are painted. For example, the web 21 and the flange 22 are surface-treated by hot-dip galvanizing and fluorine baking coating. This configuration can suppress deterioration of the bridging member 20 due to water.

[0042] (3) The building 1 comprises a first building 3 having a first wall 5, a second building 4 having a second wall 6, and a bridging member 20. The bridging member 20 spans between the first wall 5 and the second wall 6. With this configuration, the flange 22 has a cutout 25, so there is no need to process the exterior wall panel 11 for the flange 22. This makes it possible to efficiently construct the building 1.

[0043] (4) In the building 1, the first building 3 and the second building 4 each include a skeleton 10 and exterior wall panels 11 that cover the skeleton 10. The connection plates 23 of the bridging members 20 are connected to the skeleton 10. The exterior wall panels 11 are attached to the skeleton 10 so that a portion of the exterior wall panels 11 is positioned within the cutouts 25. With this configuration, the exterior wall panels 11 adjacent to the bridging members 20 are positioned near the webs 21. This improves the aesthetic appearance of the area around the bridging members 20 in the exterior wall 7B.

[0044] (5) In the building 1, a gap S is provided between the flange 22 of the bridging member 20 and the exterior wall panel 11. This configuration makes it easier to attach the exterior wall panel 11. It also prevents rainwater falling on the bridging member 20 from flowing to the exterior wall 7B.

[0045] (6) In the building 1, the bridging member 20 is exposed. With this configuration, the height and width dimensions can be reduced compared to when the bridging member 20 is covered with an exterior member. Furthermore, because the bridging member 20 is simple, the loggia space SL across which the bridging member 20 spans can be made to appear larger. Furthermore, the opening near the bridging member 20 can be enlarged in the exterior wall 7B to which the bridging member 20 is connected.

[0046] (7) The first building 3 is a main building 7 having a room R. The second building 4 is a loggia wall 8. With this configuration, the building 1 having the room R and the loggia wall 8 can be connected via a bridging member 20, thereby improving the strength of the building 1.

[0047] <Modifications> The above embodiment is an example of the form that the building 1 and the bridging member 20 can take, and is not intended to limit the form. The building 1 and the bridging member 20 can take a form different from the form exemplified in the above embodiment. Examples of such forms include forms in which part of the configuration of the embodiment is replaced, changed, or omitted, or forms in which a new configuration is added to the embodiment. Modifications of the embodiment are shown below.

[0048] As shown in Figure 8, the first building 3 and the second building 4, which are components of the building 1, may be of the same type. For example, the first building 3 and the second building 4, which are components of the building 1, may both be loggia walls 8. In one example, the two loggia walls 8 are connected to a residential building 9. A bridging member 20 is bridged between the two loggia walls 8. With this configuration, the loggia walls 8 are connected to each other via the bridging member 20, thereby improving the strength of the building 1.

[0049] 9, the first building 3 and the second building 4, which are components of the building 1, may both be main building bodies 7 having rooms R. A bridging member 20 is bridged between the two main building bodies 7 having rooms R. With this configuration, the main building bodies 7 having rooms R can be connected to each other via the bridging member 20, thereby improving the strength of the building 1.

[0050] 10 , a second building 4, which is a component of a building 1, may be part of a first building 3. For example, the first building 3 including the second building 4 is a main building 7 having a room R. A bridging member 20 is provided so as to span between a first wall 5 and a second wall 6 of the main building 7.

[0051] As shown in Figure 11, a first building 3, which is a component of a building 1, may be part of a second building 4. For example, the second building 4, which includes the first building 3, is a loggia wall 8. The loggia wall 8 extends from a residential building 9. Specifically, in the loggia wall 8, which has a first wall 5 and a second wall 6, a bridging member 20 is provided so as to span between the first wall 5 and the second wall 6.

[0052] In the embodiment, the loggia wall 8 of the second building 4 is erected away from the main building 7 of the first building 3. Alternatively, as shown in FIG. 12 , the loggia wall 8 may be connected to the main building 7. In the example shown in FIG. 12 , the first building 3, which is a component of the building 1, includes a first building portion and a second building portion intersecting the first building portion. The loggia space SL is provided to include an inside corner of the first building 3. The first building 3 has a first wall 5 as one of the walls constituting the inside corner. The loggia wall 8 of the second building 4 is positioned to face the first wall 5 of the first building 3. The loggia wall 8 has a second wall 6. The bridging member 20 is provided to bridge between the first wall 5 of the first building 3 and the second wall 6 of the loggia wall 8.
