Description

[Technical field]

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

[0002] Buildings with loggias are known (for example, Patent Document 1). The building in Patent Document 1 comprises a building body, a loggia wall provided at a position away from the building body, and an extension of a beam material connecting the building body and the loggia wall. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-015532 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the bridging member that spans two walls may be made of steel material with a flange. The end of the bridging member is connected to the structure inside the wall. In this case, the flange interferes with the exterior wall panel that covers the structure. For this reason, it is necessary to process the exterior wall panel so that it does not interfere with the flange. However, such processing of the exterior wall panel requires time and effort. [Means for solving the problem]

[0005] (1) A bridging member that solves the above problem 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 connection plate provided on at least one of both ends of the web so as to intersect with the web and connected to a structure of the first wall or a structure of the second wall, wherein the flange is provided with a cutout portion extending a predetermined length from the end of the web.

[0006] According to this configuration, the notch is provided in the flange of the bridging member, so that the end of the bridging member has a simple structure. Therefore, at the connection portion of the bridging member in the first or second wall, there is less interference between the exterior wall panel covering the framework and the flange of the bridging member. This makes it possible to efficiently install the exterior wall panel in the portion of the first or second wall where the bridging member is connected.

[0007] (2) In the bridging member of (1) above, the web and the flange are painted. With this configuration, deterioration of the bridging member caused by water can be suppressed.

[0008] (3) A building that solves the above problem comprises a first building having the first wall, a second building having the second wall, and a bridging member as described in (1) or (2) above, wherein the bridging member is bridged between the first wall and the second wall.

[0009] According to this configuration, since the flange has a notch, it is not necessary to process the exterior wall panel for the flange, which makes it possible to improve the efficiency of construction of buildings.

[0010] (4) In the building of (3) above, the first building and the second building comprise a structure and an exterior wall panel covering the structure, the connection plate of the bridging member is connected to the structure, and the exterior wall panel is attached to the structure so that a portion of the exterior wall panel is positioned within the cutout portion.

[0011] According to this configuration, the exterior wall panel adjacent to the bridging member is disposed close to the web, which improves the aesthetic appearance of the area around the bridging member in the exterior wall.

[0012] (5) In the building of (4) above, a gap is provided between the flange of the bridging member and the exterior wall panel. This configuration makes it easier to attach the exterior wall panel. Also, it is possible to prevent rainwater falling on the bridging member from flowing to the exterior wall.

[0013] (6) In the building of any one of (3) to (5) above, the bridging member is exposed. With this configuration, the height and width dimensions can be made smaller than when the bridging member is covered with an exterior member. In addition, since the bridging member is simple, the space across which the bridging member spans can be made to look larger. In addition, the opening near the bridging member can be made larger in the exterior wall to which the bridging member is connected.

[0014] (7) In any one of the buildings (3) to (6) above, the first building is a building main body having rooms or a loggia wall, and the second building is a building main body having rooms or a loggia wall. With this configuration, the building main bodies having rooms can be connected to each other via a bridging member, thereby improving the strength of the building. Also, the loggia walls can be connected to each other via a bridge member, thereby improving the strength of the building. Also, 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.

[0015] (8) In the building of any one of (3) to (6) above, the second building is a building body 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. Effect of the Invention

[0016] 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 portions of the wall where the bridging member is connected. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] A building 1 and a 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.

[0019] The building 1 includes a first building 3, a second building 4, and a bridging member 20. The bridging member 20 is disposed between a first wall 5 of the first building 3 and a second wall 6 of the second building 4.

[0020] In this embodiment, the building 1 refers to the entirety of a plurality of 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 part of the first building 3 and the second building 4. The loggia space SL may be provided between a part of the first building 3 and a part 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. The first wall 5 of the first building 3 is connected to the second wall 6 of the second building 4 via the bridging member 20, so that the building 1 becomes strong as a whole.

[0021] 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 framework 10 and an exterior wall panel 11 covering the framework 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 framework 14 and an exterior wall panel 15 covering the framework 14.

[0022] As shown in FIG. 1, in this embodiment, the first building 3 is a building body 7 having a room R. The building 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 framework 10 made of steel material 10A. An exterior wall panel 11 is attached to the framework 10 with metal fittings. The first building 3 has a first wall 5. The first wall 5 forms a part of an exterior wall 7B of the house 7A.

[0023] In this embodiment, the second building 4 is a loggia wall 8. The loggia wall 8 is placed a predetermined distance away from the house 7A. The loggia wall 8 is erected parallel to a first wall 5 of the exterior walls 7B of the house 7A. The loggia wall 8 has a framework 14 made of steel material 14A. An exterior wall panel 15 is attached to the framework 14 with metal fittings. The loggia wall 8 has a second wall 6. The second wall 6 constitutes a part of the loggia wall 8.

[0024] [Bridge member] 2 and 3, the bridging member 20 is connected to a 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 sash 7C of the first floor and lower than the sash 7D of the second floor.

[0025] 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.

[0026] 4, the bridging member 20 includes a web 21, a flange 22, and a connection plate 23. The flange 22 is provided on at least one of the upper end and the lower end of the web 21. In this embodiment, the flange 22 is provided on each of the upper end and the lower end of the web 21.

[0027] 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 structure 10 of the first wall 5 or the structure 14 of the second wall 6. The structure 10 of the first wall 5 is part of the structure 10 of the first building 3. The structure 14 of the second wall 6 is part of the structure 14 of the second building 4. In this embodiment, the connection plate 23 is provided on each of both ends of the web 21 in the longitudinal direction.

[0028] The connection plate 23 includes a first portion 23A protruding from a first surface 21A of the web 21 in the width direction DX with respect to the web 21, and a second portion 23B protruding from a second surface 21B opposite to the first surface 21A of the web 21 in the width direction DX. The first portion 23A and the second portion 23B are provided with bolt holes 23C through which bolts are inserted. The connection plate 23 is configured flat so as to be able to come into contact with the web 10B of the steel material 10A of the framework 10.

[0029] A first end 20X of the bridging member 20 is connected to the skeleton 10 of the first wall 5 via a connection plate 23. The connection 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 connection plate 23. The connection plate 23 provided at the second end 20Y is connected to the skeleton 14 with bolts and nuts.

[0030] As shown in FIG. 4, the flange 22 has a first flange portion 22A protruding from the first surface 21A of the web 21 in the width direction DX, and a second flange portion 22B protruding from the second surface 21B of the web 21 in the width direction DX.

[0031] The flange 22 is provided with a cutout portion 25. The cutout portion 25 is formed so as to extend over a predetermined length from the end of the web 21 in the longitudinal direction of the bridging member 20. The predetermined length is greater than the thickness dimension of the exterior wall panel 11. In this embodiment, the cutout portion 25 is provided at both ends of the upper flange 22 and both ends of the lower flange 22 in the longitudinal direction. Specifically, the cutout portion 25 is provided in the upper flange 22 so that both ends in the longitudinal direction are cut out. The cutout portion 25 is provided in the lower flange 22 so that both ends in the longitudinal direction are cut out. By providing such a cutout portion 25, the bridging member 20 has a plate-shaped portion 26 extending in the vertical direction near the first end 20X and near the second end 20Y. The plate-shaped portion 26 does not have a flange 22.

[0032] 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 be made of two C-shaped steels. In this case, the webs 21 of the two C-shaped steels are joined together.

[0033] The connection plate 23 is made of a steel plate. The connection plate 23 is connected to the web 21 by welding. The connection plate 23 may be joined to the web 21 by angle fittings and fasteners.

[0034] The web 21 and the flange 22 are painted. Preferably, the web 21, the flange 22 and the connection plate 23 are painted. In one example, the web 21, the flange 22 and the connection plate 23 are surface-treated by hot-dip galvanizing painting and fluorine baking painting. The fluorine baking painting is performed after the hot-dip galvanizing painting.

[0035] [Structure near the connection of bridging members] 1, a first end 20X of the bridging member 20 is connected to the structure 10 of the first building 3. A second end 20Y of the bridging member 20 is connected to the structure 14 of the second building 4. The structure of the vicinity of the connection part of the second end 20Y of the bridging member 20 is similar to the structure of the vicinity of the connection part 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.

[0036] 5 and 6, the bridging member 20 is connected perpendicularly to the steel materials 10A of the framework 10. The bridging member 20 may be connected to the steel materials 10A as beams, or may be connected to the steel materials 10A as columns.

[0037] 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 by bolts and nuts.

[0038] When the bridging member 20 is connected to the structure 10, the cutout portion 25 is disposed at the same position as the exterior wall panel 11 in the direction perpendicular to the exterior wall 7B (hereinafter, the exterior wall vertical direction DV). In other words, the plate-shaped portion 26 of the bridging member 20 is disposed 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 structure 10 so that a portion of the exterior wall panel 11 is located within the cutout portion 25.

[0039] 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.

[0040] 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.

[0041] 5, in a state in which 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 be set to a length equal to or greater than a second predetermined distance to prevent rainwater from the bridging member 20 from flowing to the exterior wall 7B.

[0042] 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 substantially composed of only the steel material 20A, it appears slimmer than the bridging portion covered by the wall material. Since the bridging member 20 is slim, in the first building 3, the opening provided in the exterior wall 7B to which the bridging member 20 is connected can be made larger than the bridging portion covered by the wall material. Specifically, the sash 7C or sash 7D can be made larger.

[0043] [Operation of this embodiment] When a member having a complex cross-sectional structure such as an H-shaped steel is used as the bridging member 20 in an exposed state, the processing of the exterior wall panel 11 becomes complex at the portion where the bridging member 20 is connected to the exterior wall 7B. For example, when an H-shaped steel is arranged between two exterior wall panels 11, it is necessary to form a notch groove into which the flange 22 is inserted in the exterior wall panel 11. The work of forming such a notch requires time or effort. In addition, the strength of the exterior wall panel 11 is reduced and the aesthetic appearance is impaired. In contrast, in this embodiment, the flange 22 is provided with a notch portion 25 that extends over 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 into which the flange 22 is inserted in the exterior wall panel 11. Therefore, the bridging member 20 can improve the efficiency of construction in the wall to which the bridging member 20 is connected.

[0044] [Effects of this embodiment] The effects of this embodiment will be described. (1) The bridging member 20 includes a web 21, a flange 22, and a connection plate 23 connected to the body 10 of the first wall 5. The flange 22 is provided with a notch 25 that extends a predetermined length from the end of the web 21.

[0045] According to this configuration, the cutout portion 25 is provided in the flange 22 of the bridging member 20, so that the end portion of the bridging member 20 has a simple structure. Therefore, at the connection portion of the bridging member 20 in the first wall 5, there is less interference between the exterior wall panel 11 and the flange 22 of the bridging member 20. This makes it possible to efficiently install the exterior wall panel 11 in the portion of the first wall 5 or the second wall 6 where the bridging member 20 is connected.

[0046] (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 caused by water.

[0047] (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 is disposed between the first wall 5 and the second wall 6. With this configuration, since the flange 22 has a notch 25, it is not necessary to process the exterior wall panel 11 for the flange 22. This makes it possible to efficiently construct the building 1.

[0048] (4) In the building 1, the first building 3 and the second building 4 include a skeleton 10 and an exterior wall panel 11 covering the skeleton 10. The connection plate 23 of the bridging member 20 is connected to the skeleton 10. 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 portion 25. With this configuration, the exterior wall panel 11 adjacent to the bridging member 20 is positioned near the web 21. This can improve the aesthetic appearance of the area around the bridging member 20 in the exterior wall 7B.

[0049] (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 easy to attach the exterior wall panel 11. In addition, rainwater falling on the bridging member 20 can be prevented from flowing to the exterior wall 7B.

[0050] (6) In the building 1, the bridging member 20 is exposed. With this configuration, the height and width dimensions can be made smaller than when the bridging member 20 is covered with an exterior member. In addition, because the bridging member 20 is simple, the loggia space SL across which the bridging member 20 spans can be made to look wider. In addition, in the exterior wall 7B to which the bridging member 20 is connected, the opening near the bridging member 20 can be made larger.

[0051] (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 the bridging member 20, thereby improving the strength of the building 1.

[0052] <Modification> 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 a form include a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0053] As shown in FIG. 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.

[0054] 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. The 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.

[0055] 10, the second building 4, which is a component of the building 1, may be a part of the 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 the first wall 5 and the second wall 6 of the main building 7.

[0056] 11, a first building 3, which is a component of a building 1, may be a part of a second building 4. For example, the second building 4 including 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 having 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.

[0057] In this embodiment, the loggia wall 8 as the second building 4 is built away from the building body 7 as the first building 3. In contrast, as shown in FIG. 12, the loggia wall 8 may be connected to the building body 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 with 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 as the second building 4 is disposed 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.
