Description

[Technical Field]

[0001] The present invention relates to a vertical furring strip support structure. [Background technology]

[0002] BACKGROUND ART Mounting structures for mounting exterior wall panels to the outer periphery of a perimeter beam or a slab are known (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-97054 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-94787 Summary of the Invention [Problem to be solved by the invention]

[0004] In the technology disclosed in Patent Document 1, the vertical furring strips of the exterior wall panels are placed on the outside of the edge of the slab and are joined to fasteners attached to the edge of the slab. Therefore, with the technology disclosed in Patent Document 1, the vertical furring strips of the exterior wall panels cannot be installed before or in parallel with the construction of the slab, which may reduce the ease of installation of the vertical furring strips.

[0005] In consideration of the above, the present invention aims to improve the workability of vertical furring strips that support exterior wall panels. [Means for solving the problem]

[0006] The vertical furring strip support structure described in claim 1 comprises an outer perimeter beam that supports the slab, a plurality of support members that are spaced apart in the material axis direction of the outer perimeter beam and each protrude from the outer perimeter beam to the outside of the room, horizontal support members formed from channel steel or angle steel that are bridged between adjacent support members and are arranged along the end faces of the slab, and vertical furring strips that are attached to the horizontal support members and support exterior wall panels.

[0007] According to the vertical furring strip support structure of claim 1, multiple support members are arranged at intervals in the material axis direction of the perimeter beam. These support members each protrude from the perimeter beam to the outside of the room. In addition, horizontal support members are bridged between adjacent support members.

[0008] The horizontal support members are made of channel steel or angle steel and are positioned along the end faces of the slab that are supported by the perimeter beams. The vertical furring strips that support the exterior wall panels are attached to the horizontal support members.

[0009] By bridging the horizontal support members across the multiple support members that protrude from the perimeter beams in this way, the vertical furring strips that support the exterior wall panels can be attached to the horizontal support members before or in parallel with the construction of the slab, thereby improving the ease of installation of the vertical furring strips.

[0010] As mentioned above, the horizontal support members are placed along the edge of the slab. In other words, the horizontal support members also function as formwork (flow stoppers) for the edge of the slab, improving the workability of the slab.

[0011] In this way, the present invention can improve the workability of the slab while also improving the workability of the vertical furring strips that support the exterior wall panels.

[0012] The vertical furring strip support structure of claim 2 is the vertical furring strip support structure of claim 1, which is provided with a position adjustment means for supporting the horizontal support member relative to the support member in an adjustable manner in the protruding direction of the support member.

[0013] According to the vertical furring strip support structure of claim 2, the position adjustment means supports the horizontal support member relative to the receiving member so that it can be adjusted in the direction of protrusion of the receiving member. By adjusting the horizontal support member in the direction of protrusion of the receiving member using this position adjustment means, the position of the vertical furring strip can be adjusted in the direction of protrusion of the receiving member. Therefore, the workability of the vertical furring strip is further improved.

[0014] The vertical furring strip support structure described in claim 3 is the vertical furring strip support structure described in claim 1 or claim 2, and is provided with a slab deck that is bridged between the outer perimeter beam and the horizontal support member and is arranged along the underside of the slab.

[0015] According to the vertical furring strip support structure of claim 3, the slab deck is bridged between the perimeter beams and the horizontal support members and is arranged along the underside of the slab. In other words, the horizontal support members also function as support members for supporting the slab deck. This further improves the workability of the slab. [Effects of the Invention]

[0016] As described above, according to the present invention, the workability of vertical furring strips that support exterior wall panels can be improved. [Brief explanation of the drawings]

[0018] (Vertical furring strip support structure) Figures 1, 2, and 3 show the outer periphery of a structure 10 to which the vertical furring strip support structure according to this embodiment is applied. The structure 10 is made up of multiple floors. The structure 10 includes perimeter beams 20, slabs 30 (see Figures 2 and 3), exterior wall panels 110, and exterior wall base units 60. Note that the slab 30 is not shown in Figure 1.

[0019] (peripheral beam) 2 and 3, the perimeter beams 20 are arranged along the perimeter of the structure and are erected on a pair of columns (not shown). The perimeter beams 20 are steel beams (perimeter steel beams) formed from H-shaped steel, and support a slab 30. The perimeter beams 20 have an upper flange portion 22 and a lower flange portion 24 that face each other in the vertical direction, and a web portion 26 that connects the upper flange portion 22 and the lower flange portion 24.

[0020] A plurality of studs (headed studs) 28 are provided on the upper surface of the upper flange portion 22. The plurality of studs 28 are embedded in a slab 30 provided on the perimeter beam 20. The perimeter beam 20 and the slab 30 are joined via these studs 28 so that shear forces can be transmitted between them.

[0021] The studs 28 are an example of a member for transmitting shear force and tension force. The outer perimeter beams 20 are not limited to steel construction, but may be made of reinforced concrete or steel-framed reinforced concrete, for example.

[0022] (Slab) The slab 30 forms the floor of a given floor of the structure 10. The slab 30 is made of reinforced concrete, with multiple slab reinforcements 32 buried inside. The end (periphery) of the slab 30 protrudes from the periphery beam 20 to the outside (arrow OUT side). An exterior wall panel 110 is arranged on the outside of the end of the slab 30.

[0023] (exterior wall panel) The exterior wall panel 110 is formed, for example, from an ALC panel or the like, and forms the exterior wall of the structure 10. The exterior wall panel 110 is disposed on the outdoor side of the perimeter beam 20, facing the side of the perimeter beam 20. The exterior wall panel 110 is supported via an exterior wall base unit 60 by a plurality of support members 40 provided on the perimeter beam 20.

[0024] (receiving member) As shown in Fig. 1, a plurality of support members 40 are provided on the exterior side of the perimeter beam 20. The plurality of support members 40 are also arranged at intervals in the material axis direction of the perimeter beam 20. Each support member 40 is made of steel.

[0025] As shown in Figure 3, each receiving member 40 has a base portion 42, a support portion 44, and a beam-side fastener portion 50. The base portion 42 is formed of a rectangular steel plate or the like in a plan view. The base portion 42 extends approximately horizontally from the upper flange portion 22 of the perimeter beam 20 toward the outside of the room. One end of the base portion 42 is butted against one end of the upper flange portion 22 of the perimeter beam 20 and joined by welding or the like.

[0026] A lateral support member 70, which will be described later, is placed on the base portion 42. The slab 30 is also provided on the base portion 42. In other words, the base portion 42 also functions as a bottom formwork for the slab 30.

[0027] 3, the support portion 44 is formed of a trapezoidal steel plate or the like when viewed from the material axis direction of the perimeter beam 20, and is provided in the form of a rib on the outdoor surface of the web portion 26 of the perimeter beam 20. This support portion 44 extends toward the outdoor surface from between the upper flange portion 22 and the lower flange portion 24 of the perimeter beam 20, and supports the underside of the base portion 42.

[0028] The support portion 44 is joined by welding or the like to the upper flange portion 22, the lower flange portion 24, the web portion 26, and the base portion 42 of the perimeter beam 20. A reinforcing rib 46 is provided on the surface of the web portion 26 of the perimeter beam 20 facing the interior (the side of the arrow IN).

[0029] 4, the beam-side fastener portion 50 is formed of a rectangular steel plate or the like when viewed from the material axis direction of the outer peripheral beam 20, and extends upward from the upper surface of the upper flange portion 22 of the outer peripheral beam 20. The lower end of this beam-side fastener portion 50 is joined by welding or the like while abutting against the upper surface of the base portion 42.

[0030] A plurality of bolt holes 52 are formed in the beam-side fastener portion 50. The plurality of bolt holes 52 are arranged at intervals in the direction in which the receiving member 40 projects (the directions of the arrows OUT and IN). Each bolt hole 52 is a through-hole that penetrates the beam-side fastener portion 50 in the thickness direction.

[0031] Each bolt hole 52 is an elongated hole extending in the direction in which the receiving member 40 projects. The beam-side fastener portion 50 is embedded in the slab 30 (see FIG. 3) while being bolted to an outer wall-side fastener portion 90 of the lateral support member 70, which will be described later.

[0032] (Exterior wall base unit) As shown in Figure 5, the exterior wall base unit 60 has horizontal support members 70 and multiple vertical furring strips 100. These horizontal support members 70 and vertical furring strips 100 are erected in a pre-assembled state by ground assembly or the like. Then, the above-mentioned exterior wall panel 110 is attached to the outdoor side of each vertical furring strip 100.

[0033] The horizontal support member 70 is a support member that supports the vertical furring strips 100 that serve as base materials for the exterior wall panel 110, while being bridged across the adjacent support members 40. In other words, the horizontal support member 70 is not a horizontal furring strip that directly supports the exterior wall panel 110.

[0034] The horizontal support members 70 are arranged along the width direction of the exterior wall foundation unit 60 (exterior wall panel 110). In addition, the horizontal support members 70 are arranged at intervals in the height direction (vertical direction) of the exterior wall foundation unit 60 (exterior wall panel 110).

[0035] 6, the horizontal support member 70 is formed from a channel steel (C-shaped steel). The horizontal support member 70 has a pair of upper and lower flange portions 72 and 74 that face each other in the height direction of the exterior wall foundation unit 60, and a web portion 76 that connects the pair of upper and lower flange portions 72 and 74.

[0036] As shown in Figure 5, one end (upper end) of multiple vertical furring strips 100 is connected to the horizontal support member 70. The multiple vertical furring strips 100 are formed, for example, from lip channel steel, and are arranged along the height direction of the exterior wall foundation unit 60 (exterior wall panel 110). The multiple vertical furring strips 100 are also arranged at intervals in the width direction of the exterior wall foundation unit 60 (exterior wall panel 110). The other end (lower end) of the multiple vertical furring strips 100 is connected to the horizontal support member 70 of another exterior wall foundation unit 60.

[0037] The ends of the vertical furring strips 100 are bolted to brackets 80 attached to the horizontal support members 70. Specifically, as shown in Fig. 6, a plurality of bolt holes 102 are formed at the top and bottom ends of the vertical furring strips 100. Each bolt hole 102 is a circular through-hole that penetrates the end of the vertical furring strip 100 in the thickness direction.

[0038] The brackets 80 are formed from steel plates or the like, and are arranged at intervals in the longitudinal direction of the horizontal support member 70. The brackets 80 are arranged with their thickness direction aligned with the longitudinal direction of the horizontal support member 70. The brackets 80 are joined in a crosswise manner to the horizontal support member 70, with their upper and lower ends extending from the horizontal support member 70 to both sides of the exterior wall foundation unit 60 in the height direction.

[0039] Specifically, a pair of slits are formed in the bracket 80. With the upper flange portion 72 and the lower flange portion 74 of the lateral support member 70 inserted into the pair of slits, the bracket 80 and the lateral support member 70 are joined by welding or the like.

[0040] The upper and lower ends of the bracket 80 serve as mounting portions 80A. A plurality of bolt holes 82 are formed in each of these mounting portions 80A. The plurality of bolt holes 82 are arranged at intervals in the direction in which the receiving member 40 protrudes. Each bolt hole 82 is a through hole that penetrates the mounting portion 80A in the thickness direction. Each bolt hole 82 is also an elongated hole (loose hole) that extends in the height direction of the exterior wall foundation unit 60.

[0041] The end of the vertical furring strip 100 is overlapped with the mounting portion 80A of the bracket 80. In this state, the mounting portion 80A of the bracket 80 and the end of the vertical furring strip 100 are bolted together by a bolt 84 and a nut 86 (see FIG. 1) inserted into the bolt holes 82, 102 of the bracket 80 and the vertical furring strip 100.

[0042] The bolts 84 are movable along the bolt holes 82 in the height direction of the exterior wall base unit 60. This makes it possible to adjust the position of the vertical furring strips 100 relative to the horizontal support members 70 in the height direction of the exterior wall base unit 60.

[0043] In this embodiment, the bolt hole 82 of the bracket 80 is an elongated hole, but at least one of the bolt holes 82, 102 of the bracket 80 and the vertical furring strip 100 can be an elongated hole. The bolt hole 82, bolt 84, and nut 86 are an example of height adjustment means. It is also possible to omit the height adjustment means and make both the bolt holes 82, 102 of the bracket 80 and the vertical furring strip 100 circular holes.

[0044] Although not shown, it is also possible to form through holes in the bracket 80 to allow the slab reinforcement 32 of the slab 30 to pass through, thereby enhancing the unity between the bracket 80 and the slab 30.

[0045] 1 and 2, an exterior wall panel 110 is attached to the exterior side of the vertical furring strip 100 with screws or the like (not shown). When the exterior wall panel 110 is attached to the vertical furring strip 100, a gap is formed between the exterior wall panel 110 and the web portion 76 of the horizontal support member 70. This gap can be filled with a fire-resistant material such as rock wool.

[0046] 1, the lateral support member 70 spans between adjacent receiving members 40. Specifically, the lateral support member 70 is placed on the base portion 42 of the adjacent receiving member 40.

[0047] In this embodiment, two types of support members 40 with different sizes of base portions 42 are provided on the peripheral beam 20. The larger base portion 42 is used to place the end portion of the lateral support member 70 (described later) in the material axis direction, and the smaller base portion 42 is used to place the middle portion of the lateral support member 70 in the material axis direction.

[0048] As shown in Figure 2, the web portion 76 of the lateral support member 70 is disposed along the exterior end face 30E of the slab 30. A plurality of studs 78 are provided on the interior side of the web portion 76. By embedding these studs 78 in the slab 30, the adhesion between the lateral support member 70 and the slab 30 is increased.

[0049] The lateral support member 70 is provided with a plurality of outer wall fastener portions 90. The outer wall fastener portions 90 are formed from a steel plate or the like, and are arranged at intervals in the longitudinal direction of the lateral support member 70. The outer wall fastener portions 90 are also arranged with their thickness direction aligned with the longitudinal direction of the lateral support member 70.

[0050] 7, the exterior wall fasteners 90 are formed of L-shaped steel plates or the like when viewed from the material axis direction of the perimeter beams 20, and are provided in the form of ribs on the interior surface of the webs 76 of the lateral support members 70. The exterior wall fasteners 90 extend from between the upper flanges 72 and lower flanges 74 of the lateral support members 70 toward the interior, and are overlapped with the beam fasteners 50.

[0051] The outer wall fastener portion 90 is joined to the upper flange portion 72, the lower flange portion 74, and the web portion 76 of the lateral support member 70 by welding or the like.

[0052] A plurality of bolt holes 92 are formed on the tip side in the extending direction of the outer wall side fastener portion 90. The plurality of bolt holes 92 are arranged at intervals in the protruding direction of the receiving member 40 (see FIG. 4).

[0053] Each bolt hole 92 is a circular through-hole that penetrates the tip end of the outer wall-side fastener portion 90 in the thickness direction. As shown in Fig. 4, the beam-side fastener portion 50 and the outer wall-side fastener portion 90 are joined by bolts 54 and nuts 56 (see Fig. 1) inserted into the bolt holes 52, 92 of the beam-side fastener portion 50 and the outer wall-side fastener portion 90 so that the beam-side fastener portion 50 and the outer wall-side fastener portion 90 can be adjusted in the protruding direction of the receiving member 40.

[0054] In this embodiment, the bolt hole 52 of the beam-side fastener portion 50 is an elongated hole, but at least one of the bolt holes 52, 92 of the beam-side fastener portion 50 and the exterior wall-side fastener portion 90 can be an elongated hole. The bolt hole 52, the bolt 54, and the nut 56 are an example of a position adjustment means. It is also possible to omit the position adjustment means and make both the bolt holes 52, 92 of the beam-side fastener portion 50 and the exterior wall-side fastener portion 90 circular holes.

[0055] (Slab deck) As shown in Figure 2, a slab deck 34 is installed between the lower flange portions 74 of the horizontal support members 70 and the upper flange portions 22 of the perimeter beams 20 between adjacent support members 40. The slab deck 34 is arranged along the underside of the slab 30. The slab deck 34 functions as the bottom formwork for the slab 30.

[0056] It should be noted that the slab deck 34 is not shown in Fig. 1. Furthermore, instead of the slab deck 34, a conventional formwork can also be used.

[0057] (Construction method of 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.

[0058] 1 shows a perimeter beam 20 installed on the perimeter of a structure 10. A plurality of support members 40 are attached to the perimeter beam 20. Furthermore, the horizontal support members 70 and vertical furring strips 100 of the exterior wall base unit 60 are previously integrated by ground assembly or the like before erecting the exterior wall base unit 60.

[0059] In this state, the exterior wall base unit 60 is lifted by a crane or the like (not shown), and the horizontal support member 70 of the exterior wall base unit 60 is spanned across the adjacent support member 40.

[0060] Specifically, as shown in Figure 4, horizontal support members 70 are placed on the base portions 42 of multiple support members 40. Next, the beam-side fastener portions 50 and exterior wall-side fastener portions 90 are joined with bolts 54 and nuts 56 (see Figure 1). At this time, the bolts 54 are moved along the bolt holes 52 in the protruding direction of the support members 40 (directions of the arrows OUT and IN), thereby positioning the vertical furring strips 100 in the protruding direction of the support members 40. In addition, the lower ends of the vertical furring strips 100 of one exterior wall foundation unit 60 are connected to the horizontal support members 70 of the other exterior wall foundation units 60.

[0061] Next, as shown in Figure 2, the slab deck 34 is placed between the lower flange portions 74 of the horizontal support members 70 and the upper flange portions 22 of the perimeter beams 20 between the adjacent support members 40. In addition, a slab deck (not shown) is also laid on the indoor side of the perimeter beams 20.

[0062] Next, slab reinforcement 32 is placed on the perimeter beams 20, support members 40, and slab deck 34, and concrete for the slab 30 is poured. In this way, the slab 30 is constructed. At this time, the web portions 76 of the horizontal support members 70 function as a formwork (flow stopper) for the outer end face 30E of the slab 30.

[0063] Next, the exterior wall panels 110 are attached to the multiple vertical furring strips 100 of the exterior wall foundation units 60. As a result, the exterior wall panels 110 are supported on the perimeter beams 20 via the exterior wall foundation units 60 and the multiple support members 40.

[0064] The exterior wall panel 110 can be attached to a plurality of vertical furring strips 100 before or after construction of the slab 30, or in parallel with construction of the slab 30. The above construction procedure can also be modified as appropriate.

[0065] (action) Next, the operation of this embodiment will be described.

[0066] As shown in Figure 1, multiple support members 40 are arranged at intervals in the material axis direction of the perimeter beams 20. These support members 40 each protrude from the perimeter beams 20 to the outside of the room (arrow OUT side). In addition, horizontal support members 70 of the exterior wall base unit 60 are bridged between adjacent support members 40.

[0067] 2 and 3, the horizontal support member 70 is formed of a channel steel, and its web portion 76 is arranged along the outer end face 30E of the slab 30. Vertical furring strips 100 that support the exterior wall panels 110 are attached to this horizontal support member 70.

[0068] In this embodiment, by bridging the horizontal support members 70 across the multiple support members 40 that protrude from the perimeter beams 20, the vertical furring strips 100 that support the exterior wall panels 110 can be attached to the horizontal support members 70 before or in parallel with the construction of the slab 30. This improves the ease of installation of the vertical furring strips 100.

[0069] In particular, in this embodiment, the horizontal support members 70 and the vertical furring strips 100 are integrated in advance by ground assembly or the like before erecting the exterior wall base unit 60. This makes it easy to attach multiple vertical furring strips 100 to the horizontal support members 70. Therefore, the workability of the vertical furring strips 100 is further improved.

[0070] As described above, the web portion 76 of the lateral support member 70 is disposed along the exterior end face 30E of the slab 30. In other words, the lateral support member 70 also functions as a formwork (flow stopper) for the exterior end face 30E of the slab 30. This also improves the workability of the slab 30.

[0071] In this way, in this embodiment, the workability of the vertical furring strips 100 that support the exterior wall panels 110 can be improved, while the workability of the slab 30 can also be improved.

[0072] Furthermore, the multiple bolt holes 52 formed in the beam-side fastener portion 50 of the receiving member 40 are elongated holes extending in the direction in which the receiving member 40 protrudes. By moving the bolts 54 along these bolt holes 52, the position of the vertical furring strip 100 can be adjusted in the direction in which the receiving member 40 protrudes.

[0073] Furthermore, the multiple bolt holes 82 formed in the brackets 80 of the horizontal support members 70 are elongated holes that extend in the height direction of the exterior wall base unit 60. By moving the bolts 84 along these bolt holes 82, the position of the vertical furring strips 100 can be adjusted in the height direction of the exterior wall base unit 60. This further improves the ease of installation of the vertical furring strips 100.

[0074] The slab deck 34 is also bridged between the perimeter beams 20 and the horizontal support members 70, and is positioned along the underside of the slab 30. In other words, the horizontal support members 70 also function as support members for supporting the slab deck 34. This further improves the workability of the slab 30.

[0075] (Variation) Next, a modification of the above embodiment will be described.

[0076] In the above embodiment, the lateral support member 70 is formed of a channel steel. However, the lateral support member 70 is not limited to a channel steel, and may be formed of, for example, an angle steel (L-shaped steel) in which the upper flange portion 72 is omitted from the lateral support member 70. Furthermore, the configurations of the receiving member 40 and the vertical furring strips 100 can also be changed as appropriate.

[0077] In the above embodiment, the horizontal support members 70 and the multiple vertical furring strips 100 are integrated in advance by ground assembly or the like before erection. However, for example, the upper and lower horizontal support members 70 and the multiple vertical furring strips 100 may be integrated in advance by ground assembly or the like before erection. Also, without integrating the horizontal support members 70 and the multiple vertical furring strips 100 in advance before erection, for example, it is possible to attach the vertical furring strips 100 to the horizontal support members 70 after bridging the horizontal support members 70 across adjacent support members 40.

[0078] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it goes without saying that the present invention can be implemented in various forms as long as it does not deviate from the gist of the present invention.
