Summary of the Invention

Problems to be Solved by the Invention

[0005] Generally, a plurality of vertical barrel edges for supporting exterior materials are respectively supported by a plurality of gusset plates attached to an outer peripheral beam. In this case, it is necessary to attach a plurality of gusset plates to the outer peripheral beam according to the number of vertical barrel edges, so the construction of the gusset plates is laborious.

[0006] In consideration of the above facts, an object of the present invention is to improve the workability of gusset plates attached to an outer peripheral beam and supporting vertical barrel edges for exterior materials.

Means for Solving the Problems

[0007] Regarding the first aspectThe vertical furring strip support structure comprises: an outer perimeter beam erected on the outer perimeter column and supporting the slab; a plurality of gusset plates positioned below the slab and spaced apart in the direction of the outer perimeter beam's material axis, extending outward from the outer perimeter beam or the outer perimeter column; an intermediate support beam positioned below the slab and supported by the plurality of gusset plates; a plurality of brackets provided on the intermediate support beam and spaced apart in the direction of the intermediate support beam's material axis; and a plurality of vertical furring strips attached to the brackets and supporting the exterior material.

[0008] First aspect In the vertical furring strip support structure described herein, the outer perimeter beam is erected on the outer perimeter column and supports the slab. Multiple gusset plates extend outward from this outer perimeter beam or column. These multiple gusset plates are positioned below the slab and spaced apart in the direction of the outer perimeter beam's axial length. The intermediate support beam is supported by these gusset plates.

[0009] The intermediate support beam is positioned below the slab. Multiple brackets are provided on this intermediate support beam. These brackets are spaced apart along the axial direction of the intermediate support beam. Vertical furring strips, which support the exterior cladding, are attached to these brackets.

[0010] Thus, in this invention, by supporting an intermediate support beam, which is provided with multiple brackets for supporting vertical furring strips, with multiple gusset plates, the number of gusset plates can be reduced to less than the number of vertical furring strips. Therefore, the work required to attach the gusset plates to the outer perimeter beam is reduced, improving the workability of the gusset plates.

[0011] Furthermore, in this invention, when attaching an intermediate support beam to an outer beam or outer column via multiple gusset plates, construction errors in the outer beam or outer column can be absorbed. Therefore, the construction accuracy of multiple vertical furring strips can be improved.

[0012] Furthermore, since adjacent gusset plates are connected by intermediate support beams, these beams function as bracing members for the gusset plates. Therefore, the swaying of the gusset plates during an earthquake can be suppressed. In addition, since there is no need to provide separate bracing members for the gusset plates in addition to the intermediate support beams, costs can be reduced.

[0013] Regarding the second aspect The vertical purlin support structure is, Regarding the first aspect In the vertical furring strip support structure, the bracket extends from the intermediate support beam toward the exterior side.

[0014] Second aspect In the vertical furring strip support structure described herein, the bracket extends outward from the intermediate support beam. This allows the extension length of the gusset plate extending from the outer perimeter beam to be shortened compared to, for example, a configuration in which the bracket extends upward or downward from the intermediate support beam. Therefore, the swaying of the gusset plate can be suppressed during an earthquake.

[0015] Regarding the third aspect The vertical purlin support structure is, Regarding the first aspect In the vertical furring strip support structure, a slab deck is provided which is arranged along the lower surface of the slab that can bends outward from the outer peripheral beam and is supported by a plurality of gusset plates, and the slab deck is provided with a concrete stopper which is arranged along the outer end face of the slab.

[0016] Third aspect In the vertical furring strip support structure described herein, the slab deck is positioned along the underside of the slab that cantilevers outward from the outer perimeter beam. This slab deck is supported by multiple gusset plates. In other words, the gusset plates serve as both intermediate support beams and support members for the slab deck. Therefore, since there is no need to provide separate support members for the slab deck in addition to the gusset plates, costs can be reduced.

[0017] In addition, the slab deck is provided with a concrete stop portion arranged along the outdoor-side end face of the slab. Thereby, the concrete placed on the slab deck is suppressed from flowing down from the slab deck. Therefore, the workability of the slab is improved.

[0018] Regarding the fourth aspect The vertical flange support structure is Appearances 1 to 3 any one of related to In the vertical flange support structure, the number of the gusset plates is less than the number of the vertical flanges.

[0019] Fourth aspect According to the vertical flange support structure according to , the number of the gusset plates is less than the number of the vertical flanges. Therefore, the work of attaching the gusset plates to the outer peripheral beam is reduced, and the workability of the gusset plates is improved.

Effect of the Invention

[0020] As described above, according to the present invention, the workability of the gusset plate attached to the outer peripheral beam and supporting the vertical flange for the exterior material can be improved.

Mode for Carrying Out the Invention

[0022] Hereinafter, the vertical flange support structure according to one embodiment will be described with reference to the drawings.

[0023] (Vertical framing support structure) Figure 1 shows the outer perimeter of a structure (building) 10 to which the vertical furring strip support structure according to this embodiment is applied. The structure 10 consists of multiple floors. As shown in Figure 2, the structure 10 comprises outer perimeter columns 20, outer perimeter beams 30, slabs 40, intermediate support beams 60, and exterior panels 80.

[0024] Note that the exterior panel 80 is not shown in Figure 1. Also, the slab 40 and the slab deck 42 are not shown in Figure 2. Furthermore, the arrows IN shown in each figure indicate the interior side of the structure 10, and the arrows OUT indicate the exterior side of the structure 10.

[0025] (Perimeter pillars) The outer perimeter columns 20 are arranged at intervals around the outer perimeter of the structure 10. These outer perimeter columns 20 are steel columns (outer perimeter steel columns) formed from square steel pipes. In addition, outer perimeter beams 30 are installed between adjacent outer perimeter columns 20.

[0026] Furthermore, the outer perimeter columns 20 are not limited to square steel pipes; they may also be formed from round steel pipes or H-shaped steel. In addition, the outer perimeter columns 20 are not limited to steel frames; they may also be made of reinforced concrete or steel-reinforced concrete, etc.

[0027] (Perimeter beam) The outer perimeter beams 30 are arranged along the outer perimeter of the structure 10. Furthermore, the outer perimeter beams 30 are installed vertically, spaced apart from the outer perimeter columns 20 and other outer perimeter columns (not shown). These outer perimeter columns 20 and outer perimeter beams 30 constitute the outer perimeter frame.

[0028] As shown in Figure 3, the outer perimeter beam 30 is a steel beam (outer perimeter steel beam) formed from H-shaped steel. This outer perimeter beam 30 has an upper flange portion 32 and a lower flange portion 34 that face each other in the vertical direction, and a web portion 36 that connects the upper flange portion 32 and the lower flange portion 34.

[0029] Multiple studs 38 are provided on the upper surface of the upper flange portion 32. The multiple studs 38 are spaced apart in the direction of the axial direction of the outer perimeter beam 30. In addition, the multiple studs 38 protrude upward from the upper surface of the upper flange portion 32 and are embedded in the slab 40. The outer perimeter beam 30 and the slab 40 are joined via these studs 38 in a way that allows for the transmission of shear forces.

[0030] Note that the studs 38 can be omitted as appropriate. Also, the outer perimeter beams 30 are not limited to steel frame construction; they may also be made of reinforced concrete or steel-reinforced concrete, etc.

[0031] (Slavic) Slab 40 is made of reinforced concrete, with slab reinforcement (not shown) embedded inside. Slab 40 is also erected on the outer perimeter beam 30 and an adjacent inner beam (not shown) to the outer perimeter beam 30. Slab 40 has an overhang 40A that extends outward from the outer perimeter beam 30.

[0032] The overhang section 40A is formed by pouring concrete onto a slab deck 42 that is erected on the outer perimeter beam 30 and the intermediate support beam 60, which will be described later. Multiple gusset plates 50A, 50B (see Figure 2) are arranged on the underside of this slab deck 42.

[0033] (Gusset plate) As shown in Figure 2, the multiple gusset plates 50A and 50B support the intermediate support beam 60 and also serve as support members for the slab deck 42. In other words, the multiple gusset plates 50A and 50B serve as support members for both the intermediate support beam 60 and the slab deck 42.

[0034] Multiple gusset plates 50A and 50B are formed from steel plates or the like and are arranged at intervals along the axial direction of the outer perimeter beam 30. Furthermore, multiple gusset plates 50A and 50B are provided on the exterior side (exterior panel 80 side) of the outer perimeter columns 20 and outer perimeter beam 30, respectively. The number of these gusset plates 50A and 50B is less than the number of vertical furring strips 70 and exterior brackets 64.

[0035] The configurations of gusset plates 50A and 50B are the same. Therefore, the configuration of gusset plate 50A, which is installed on the outdoor side of the outer perimeter beam 30, will be described below, and the configuration of gusset plate 50B, which is installed on the outdoor side of the outer perimeter column 20, will be omitted.

[0036] As shown in Figure 3, the gusset plate 50A, which is provided on the exterior side of the outer perimeter beam 30, is positioned below the slab 40. The gusset plate 50A is formed in an L-shape when viewed in the thickness direction (the axis direction of the outer perimeter beam 30). This gusset plate 50A has a rib-like portion 52 and an extended portion 54.

[0037] The rib-like portion 52 is provided in a rib-like manner on the outdoor outer surface of the web portion 36 of the outer peripheral beam 30. Furthermore, the rib-like portion 52 extends across the upper flange portion 32 and the lower flange portion 34 of the outer peripheral beam 30, and is joined to the upper flange portion 32, the lower flange portion 34, and the web portion 36 by welding or the like.

[0038] In this embodiment, a rib plate 56 is provided on the side of the outer perimeter beam 30 opposite to the rib-shaped portion 52 relative to the web portion 36. However, the rib plate 56 can be omitted as appropriate.

[0039] The extension portion 54 of the gusset plate 50A extends outward from the upper part of the rib-shaped portion 52 along the underside of the slab 40 (slab deck 42). An intermediate support beam 60 is joined to the tip of this extension portion 54 in the direction of extension. The slab deck 42, which will be described later, is provided on top of the extension portion 54.

[0040] (Intermediate support beam) The intermediate support beam 60 is a beam that supports multiple vertical furring strips 70 and also reinforces multiple gusset plates 50A. In other words, the intermediate support beam 60 serves as both a support member for multiple vertical furring strips 70 and a reinforcing member (bracing member) for multiple gusset plates 50A.

[0041] The intermediate support beam 60 is positioned along the outer perimeter of the structure 10. More specifically, the intermediate support beam 60 is positioned between the outer perimeter beam 30 and the exterior panel 80, along the material axis direction of the outer perimeter beam 30. The intermediate support beam 60 is a steel beam formed from square steel pipes. Multiple inner brackets 62 are provided on the inner surface of the intermediate support beam 60 on the interior side (outer perimeter beam 30 side). On the other hand, multiple outer brackets 64 are provided on the outer surface of the intermediate support beam 60 on the exterior side (exterior panel 80 side).

[0042] Furthermore, the intermediate support beam 60 is not limited to square steel pipes; for example, it may be formed from H-shaped steel or C-shaped steel. Also, the intermediate support beam 60 is not limited to steel frame construction; it may be reinforced concrete or steel-reinforced concrete.

[0043] As shown in Figures 2 to 4, the multiple inner brackets 62 are formed from steel plates or the like, and are arranged at intervals in the axial direction of the intermediate support beam 60 according to the number of gusset plates 50A. The multiple inner brackets 62 also extend from the inner surface of the intermediate support beam 60 toward the interior. The ends of the multiple gusset plates 50A are joined to these inner brackets 62 by bolts 66 and nuts 68 (see Figure 1) (bolted connection).

[0044] The multiple inner brackets 62 may be joined to the inner surface of the intermediate support beam 60 by welding or the like at the factory or site yard, or they may be joined to the inner surface of the intermediate support beam 60 by welding or the like at the site.

[0045] Multiple outer brackets 64 are formed from steel plates or the like, and are arranged at intervals in the direction of the intermediate support beam 60's material axis, corresponding to the number of vertical furring strips 70. Furthermore, the multiple outer brackets 64 extend outwards from the outer surface of the intermediate support beam 60. The vertical furring strips 70 are attached to these outer brackets 64, for example, by bolts 72 and nuts 74 (see Figure 2).

[0046] As shown in Figure 3, in the lower floor's intermediate support beam 60, two vertical furring strips 70 are connected via an outer bracket 64. On the other hand, as shown in Figure 5, in the upper floor's intermediate support beam 60, the middle section of one vertical furring strip 70 in the direction of the material axis is attached to the outer bracket 64. Therefore, the outer bracket 64 on the lower floor is larger than the outer bracket 64 on the upper floor.

[0047] Note that the outer bracket 64 is just one example of a bracket. Furthermore, multiple outer brackets 64 may be joined to the outer surface of the intermediate support beam 60 by welding or other means at the factory or site yard, or they may be joined to the outer surface of the intermediate support beam 60 by welding or other means at the construction site. Also, the outer brackets 64 may extend from the intermediate support beam 60 not to the exterior, but to at least one of the upper and lower sides.

[0048] (Vertical furring strips) As shown in Figure 2, the multiple vertical furring strips 70 are a base material that supports the exterior panel 80. The exterior panel 80 is formed from an exterior wall panel such as ALC. The exterior panel 80 is positioned on the exterior side of the multiple vertical furring strips 70 and is supported by these vertical furring strips 70. Note that the exterior panel 80 is just one example of an exterior material.

[0049] Multiple vertical furring strips 70 are formed from C-shaped steel and are spaced apart in the width direction of the exterior panel 80. The exterior panel 80 is fixed to the exterior surface 70S2 of these vertical furring strips 70 on the outdoor side by screws or the like (not shown).

[0050] (Deck for slabs) As shown in Figures 3 and 5, the slab deck 42 is formwork for the overhang portion 40A of the slab 40 that can be projected outward from the outer perimeter beam 30. This slab deck 42 is formed from a flat deck or deck plates.

[0051] The slab deck 42 is installed on the upper surface of the outer perimeter beam 30 and the upper surface of the intermediate support beam 60. The slab deck 42 is also supported from below by multiple gusset plates 50A that connect the outer perimeter beam 30 and the intermediate support beam 60. The slab deck 42 is provided with concrete retaining sections 42T.

[0052] The concrete retaining section 42T functions as formwork to form the exterior end face 40E of the slab 40. This concrete retaining section 42T extends upward in a wall-like manner from the exterior end of the slab deck 42 along the interior surface 70S1 of the vertical furring strip 70.

[0053] Concrete for the slab 40 is poured onto the slab deck 42. This forms the overhang 40A of the slab 40. In addition, the concrete retaining portion 42T forms the outdoor end face 40E of the overhang 40A (slab 40). In other words, when the overhang 40A (slab 40) is formed, the concrete retaining portion 42T is positioned along the outdoor end face 40E of the overhang 40A.

[0054] (Construction method for vertical furring strip support structure) Next, an example of a construction method for the vertical furring strip support structure according to this embodiment will be described.

[0055] Figure 4 shows the outer perimeter beam 30 installed on the outer perimeter of the structure 10. Multiple gusset plates 50A, 50B (see Figure 2) are attached to the outer perimeter beam 30.

[0056] In this state, the intermediate support beam 60 is lifted by a crane or the like (not shown), and the multiple inner brackets 62 of the intermediate support beam 60 are bolted to the gusset plates 50A and 50B (see Figure 2) of the outer perimeter beam 30 and outer perimeter column 20, respectively. Note that the multiple inner brackets 62 and multiple outer brackets 64 are pre-attached to the intermediate support beam 60 by welding or the like.

[0057] Next, the vertical purlins 70 are lifted using a crane or the like (not shown), and the vertical purlins 70 are bolted to the outer brackets 64 of the intermediate support beams 60.

[0058] Next, a slab deck 42 is erected on the upper surface of the outer perimeter beam 30 and the upper surface of the intermediate support beam 60, and the slab deck 42 is placed on multiple gusset plates 50A, 50B (see Figure 2). In addition, formwork for the slab 40 (not shown) is appropriately installed on the interior side of the outer perimeter beam 30.

[0059] Next, reinforcement bars (not shown) are placed on the slab deck 42, and concrete for the slab 40 is poured. At this time, the concrete retaining portion 42T of the slab deck 42 functions as formwork (flow stopper) for the exterior end face 40E of the slab 40. This forms the slab 40, including the overhang portion 40A.

[0060] Next, as shown in Figure 3, the exterior panels 80 are attached to the multiple vertical furring strips 70. In this way, the exterior panels 80 are supported by the outer perimeter beams 30 and outer perimeter columns 20 via the multiple vertical furring strips 70, the intermediate support beams 60, and the multiple gusset plates 50A.

[0061] The exterior panels 80 can be attached to multiple vertical furring strips 70 before or after the construction of the slab 40, or in parallel with the construction of the slab 40. Furthermore, the above construction procedure can be modified as appropriate.

[0062] (Mechanism of Action and Effects) Next, the operation and effects of this embodiment will be described.

[0063] As shown in Figure 2, according to this embodiment, the outer perimeter beam 30 is erected on the outer perimeter column 20 and supports the slab 40 (see Figure 3). Multiple gusset plates 50A and 50B extend outwards from the outer perimeter beam 30 or outer perimeter column 20.

[0064] Multiple gusset plates 50A and 50B are positioned below the slab 40 (see Figure 3) and spaced apart in the direction of the outer perimeter beam 30. The intermediate support beam 60 is supported by these gusset plates 50A and 50B.

[0065] As shown in Figure 3, the intermediate support beam 60 is positioned below the slab 40. Multiple outer brackets 64 are provided on this intermediate support beam 60. The multiple outer brackets 64 are spaced apart in the direction of the intermediate support beam 60's material axis. Vertical furring strips 70 that support the exterior panels 80 are attached to these outer brackets 64.

[0066] In this embodiment, by supporting the intermediate support beam 60, which is provided with multiple outer brackets 64 that support the vertical furring strips 70, with multiple gusset plates 50A and 50B, the number of gusset plates 50A and 50B can be reduced to less than the number of vertical furring strips 70. Therefore, the work required to attach the gusset plates 50A and 50B to the outer perimeter beam 30 is reduced, improving the workability of the gusset plates 50A and 50B.

[0067] Furthermore, as shown in Figure 2, in this embodiment, when attaching the intermediate support beam 60 to the outer perimeter beam 30 or outer perimeter column 20 via multiple gusset plates 50A, 50B, construction errors of the outer perimeter beam 30 or outer perimeter column 20 can be absorbed. Therefore, the construction accuracy of the multiple vertical furring strips 70 can be improved.

[0068] Furthermore, since the intermediate support beam 60 connects adjacent gusset plates 50A and 50B, the intermediate support beam 60 functions as a bracing member for the gusset plates 50A and 50B. Therefore, the swaying of the gusset plates 50A and 50B during an earthquake can be suppressed. In addition, since there is no need to provide a separate bracing member for the gusset plates 50A and 50B in addition to the intermediate support beam 60, costs can be reduced.

[0069] Furthermore, the outer bracket 64 extends outward from the intermediate support beam 60. This allows the extension length of the gusset plates 50A and 50B extending from the outer perimeter beam 30 to be shortened, compared to, for example, a configuration in which the outer bracket 64 extends upward or downward from the intermediate support beam 60. Therefore, the swaying of the gusset plates 50A and 50B during an earthquake can be further suppressed.

[0070] Furthermore, as shown in Figure 3, the slab deck 42 is positioned along the underside of the slab 40 that can bends outward from the outer perimeter beam 30. This slab deck 42 is supported by multiple gusset plates 50A and 50B. In other words, the gusset plates 50A and 50B serve as both support members for the intermediate support beam 60 and the slab deck 42. Therefore, since there is no need to provide separate support members for the slab deck 42 in addition to the gusset plates 50A and 50B, costs can be reduced.

[0071] Furthermore, the slab deck 42 is provided with a concrete stopper 42T positioned along the exterior end face 40E of the slab 40. This prevents the concrete for the slab 40, which has been poured onto the slab deck 42, from flowing off the slab deck 42. Consequently, the constructability of the slab 40 is improved.

[0072] (modified version) Next, a modified example of the above embodiment will be described.

[0073] In the above embodiment, gusset plates 50A and 50B are provided on the outer perimeter columns 20 and outer perimeter beams 30. However, gusset plates 50A and 50B can be provided on at least one of the outer perimeter columns 20 and outer perimeter beams 30. For example, gusset plates 50B may be provided only on adjacent outer perimeter columns 20, or gusset plates 50A may be provided only on the outer perimeter beams 30.

[0074] Furthermore, in the above embodiment, a protruding portion 40A is provided on the slab 40. However, the protruding portion 40A and the slab deck 42 can be omitted as appropriate.

[0075] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and of course, the invention can be implemented in various forms without departing from the spirit of the present invention.
