[0001] The present invention relates to a runner support fitting provided on a structural beam for supporting a runner material.

Background Art

[0002] Conventionally, as a structure of an interior wall such as a partition wall, a partition wall, or a partition wall, a structural beam that supports a floor slab on the upper surface of one side in the width direction of the upper flange, and a mortar receiving plate having an L-shaped cross section that is supported on the side where the floor slab is not supported on the upper surface of the upper flange, mortar filled between the mortar receiving plate and the floor slab, a runner material supported by the mortar, a stud supported by the runner material, and a fireproof coating material covering the floor beam are known (see, for example, Patent Document 1). According to this structure, the upper surface of the structural beam can be covered with the floor slab and mortar, and the fireproof coating material does not need to be wound up to the upper surface of the structural beam.

[0003] However, in the structure of the interior wall as described above, there is a possibility that the accuracy of the wavy wall finish deteriorates due to the filling pressure of the mortar on the mortar receiving plate. Therefore, a structure has been proposed in which a metal runner support fitting is used to fix the runner material instead of the mortar (see Patent Document 2). In this structure, the runner support fitting is formed in a U-shape in side view, and one end of the fireproof coating material that covers the beam from below is wound inside the runner support fitting and connected to the side surface of the floor slab above the structural beam, thereby fireproof coating the structural beam.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the case of runner support brackets like those in Patent Document 2, the lower surface of the U-shaped runner support bracket is brought into contact with the upper surface of the structural beam and fastened with bolts and nuts. However, since there is no gap in the runner support bracket to insert power tools, the bolts and nuts are fastened using manual tools such as spanners and wrenches, which makes the installation time-consuming.

[0006] Therefore, the present invention aims to provide a runner support bracket and wall structure that can reduce the amount of work involved. [Means for solving the problem]

[0007] The first invention, which solves the above problems, is a runner support fitting interposed between a structural beam of a building and a runner material laid on the structural beam to form the base of an interior wall, comprising: a main body having a bottom plate fixed to the upper surface of the structural beam; a receiving portion positioned above the bottom plate at a distance from it and having a tool insertion gap; and a connecting portion connecting the bottom plate and the receiving portion; and an upper body positioned parallel to the bottom plate and on the receiving portion so as to close the tool insertion gap, and which can be moved to a state where the tool insertion gap is open, and on which the runner material is fixed.

[0008] The second invention is a runner support fitting of the first invention, wherein the main body is formed by bending a metal plate, and the upper body is flat and thinner than the metal plate forming the main body.

[0009] The third invention is a runner receiving fitting of the first or second invention, wherein the upper body is slidably fixed to the receiving portion, and the sliding motion transitions the tool insertion gap between an open state and a closed state.

[0010] The fourth invention is a runner support fitting according to the first to third inventions, wherein the upper body is detachably engaged with the receiving portion to close the tool insertion gap.

[0011] Although a third invention in which the upper body is slidable relative to the receiving portion and a fourth invention in which the upper body is detachably engaged with the receiving portion have been described above, the upper body may be of any configuration that allows it to transition between a state in which the tool insertion gap of the receiving portion is closed and a state in which it is open.

[0012] The fifth invention is a wall structure formed by fixing the runner material on the runner support fittings of the first to fourth inventions, erecting studs on the runner material to form a wall base, and attaching an interior wall surface material to the wall base, wherein the main body of the runner support fitting is U-shaped in side view, and the end of a fire-resistant covering material that covers at least the side of the structural beam is attached to the upper surface of the bottom plate of the runner support fitting.

[0013] The sixth invention is a wall structure of the fifth invention, wherein the interior wall surface material is arranged across the runner material and the lower floor wall base formed below the structural beam and fixed to each of them. [Effects of the Invention]

[0014] According to the runner support fitting of the first invention, the main body comprises a bottom plate, a receiving portion positioned above the bottom plate at a distance, and a connecting portion connecting the bottom plate and the receiving portion. A tool insertion gap is formed in the receiving portion of the main body, and an upper body is formed to be positioned parallel to the bottom plate in the receiving portion so as to close the tool insertion gap, and to be able to move to a state where the tool insertion gap is open. By moving the upper body to a state where the tool insertion gap is open, a tool can be inserted into the tool insertion gap from above and bolts and nuts can be fastened to fix the runner support fitting to the structural beam. Alternatively, by moving the upper body to a state where the tool insertion gap is closed, the runner material can be screwed onto the upper body, thereby reducing the labor required for construction.

[0015] According to the runner support fitting of the second invention, the upper body is formed thinner than the metal plate forming the main body, so the runner support fitting as a whole can be formed with sufficient strength, and because the upper body, which is the position where the runner material is fixed, is thin, it is easier to drive screws when fixing the runner material, thus reducing the labor required for construction while maintaining sufficient strength.

[0016] According to the runner support fitting of the third invention, the upper body is slidably fixed to the receiving part, allowing the tool insertion gap to transition between an open and closed state. When fixing the runner support fitting to a structural beam, the tool insertion gap can be opened while a part of the upper body is hooked onto the receiving part. This allows a tool to be inserted into the tool insertion gap to fasten the main body to the structural beam, and then the upper body, which is partially hooked onto the receiving part, can be slid to close the tool insertion gap. This eliminates the need to separately store the upper body during the work, reducing the effort required during construction.

[0017] According to the runner support fitting of the fourth invention, since the upper body is detachably engaged with the receiving part, when fixing the runner support fitting to the structural beam, the upper body can be removed from the receiving part to open the tool insertion gap, a tool can be inserted into the tool insertion gap to fasten the main body to the structural beam, and then the tool insertion gap can be closed by attaching the upper body to the receiving part. This reduces construction time with an extremely simple shape.

[0018] According to the wall structure of the fifth invention, the main body of the runner support bracket is U-shaped in side view, and the end of the fire-resistant covering material that covers at least the side of the structural beam is attached to the upper surface of the bottom plate of the runner support bracket, so that the fire-resistant covering material can be wrapped around to the upper surface of the structural beam without interfering with the runner support bracket.

[0019] According to the wall structure of the sixth invention, the interior wall surface material is positioned across the runner material and the lower floor wall base formed below the structural beam and fixed to each of them, so that the upper and lower wall base materials are connected by the interior wall surface material, and the wall structure can be formed firmly.

Embodiments for Carrying Out the Invention

[0021] The embodiments of the runner support bracket 1 and wall structure 2 of the present invention will be described below with reference to the figures. The wall structure 2 is, for example, a partition wall structure that separates a dwelling unit 3 and an atrium 4 in an apartment building. The building in the present invention is not limited to apartment buildings, but may be various facilities or detached houses, etc. Furthermore, the wall structure 2 is not limited to a partition wall, but may be, for example, a partition wall, a vertical shaft partition such as an elevator room, or a common corridor wall separating an outdoor common corridor from a dwelling unit, and the wall structure 2 should have fire resistance to prevent the spread of fire in the event of a fire. Furthermore, the wall structure 2 is not limited to separating a dwelling unit 3 and an atrium 4, but may separate two spaces where one side of the wall structure 2 is at a normal floor height and the other side is at a low floor height, such as a bathroom, or it may separate two spaces where both sides of the wall structure 2 are atriums or low floors.

[0022] As shown in Figure 1, the wall structure 2 comprises a structural beam 5 supported by a structural column (not shown), a lower floor wall base 6 whose upper end is fixed to the structural beam 5, a floor slab 7 whose end is fixed to half of the widthwise upper surface of the structural beam 5, a runner support bracket 1 fixed to the upper surface of the structural beam 5 on the side opposite to the floor slab 7, an upper floor wall base 8 fixed to the upper surfaces of the floor slab 7 and the runner support bracket 1 respectively, a fire-resistant covering material 9 covering the structural beam 5, and an interior wall surface material 10 fixed to the upper floor wall base 8 and the lower floor wall base 6.

[0023] The structural beam 5 is formed from an H-shaped steel beam horizontally erected by connecting the upper and lower flanges 11 and 12 with a web 13. Although not shown, the upper and lower flanges 11 and 12 are provided with circular holes for fixing various members. The structural beam 5, in combination with the structural columns, forms the structural frame of a heavy steel rigid frame structure. A runner attachment member (not shown) is attached to the lower flange 12 of the structural beam 5, supporting the upper end of the lower floor wall base 6. The lower floor wall base 6 is a steel base formed by combining lower floor runner members 15 provided on the floor and ceiling surfaces of the lower floor, and a plurality of lower floor studs 16 erected between the lower floor runner members 15. Of the lower floor runner members 15 that make up the lower floor wall base 6, the upper lower floor runner member 15 is fixed to the lower flange 12 via a runner attachment member.

[0024] The floor slab 7 is, for example, an ALC panel. The ends of the floor slab 7 are placed and fixed to half of the width of the upper flange 11 of the structural beam 5. The sides of the floor slab 7 are located approximately in the center of the width of the upper surface of the upper flange 11 of the structural beam 5. A moisture-proof sheet 17 and particle board 18 are laid on the upper surface of the floor slab 7 to form a floor finishing layer. The floor slab 7 is connected to the upper flange 11 of the structural beam 5 by fixing fittings (not shown).

[0025] The runner support fitting 1 is a fitting installed between the structural beam 5 and the runner material 19, which is laid on the structural beam 5 and forms the upper floor wall base 8. As shown in Figure 2, the runner support fitting 1 comprises a main body 20 fixed to the structural beam 5 and an upper body 21 to which the runner material 19 is fixed.

[0026] The main body 20 is U-shaped in side view and has a rectangular flat bottom plate 22 fixed to the upper surface of the structural beam 5, a receiving portion 23 positioned parallel to and above the bottom plate 22 at a distance, and a connecting portion 24 connecting the bottom plate 22 and the receiving portion 23. The main body 20 is formed into a U-shape by bending a flat steel plate. The bottom plate 22 has an insertion hole 27 formed approximately in its center for inserting a bolt 25 to fix the bottom plate 22 to the upper flange 11 of the structural beam 5. The receiving portion 23 is rectangular flat and has a tool insertion gap 28 that is open except for the periphery. The tool insertion gap 28 is a rectangular through hole that is open except for the periphery of the receiving portion 23. The tool insertion gap 28 is not limited to a through hole formed in the receiving portion 23; a part of the peripheral edge of the receiving portion 23 may be open, and the receiving portion 23 may be shaped like a C or a U, with the inside of the C or U shape being the tool insertion gap 28. The bottom plate 22 and the receiving portion 23 are connected by a connecting portion 24. The connecting portion 24 is positioned to extend upward from the center in the width direction of the upper flange 11 of the structural beam 5. The shape of the main body 20 is not limited to a U-shape in side view, but it is preferable that the shape of the bottom plate 22 allows the fire-resistant covering material 9, described later, to be wrapped around the upper surface of the structural beam 5 from the side.

[0027] As shown in Figures 2 and 3, the upper body 21 is positioned above the receiving portion 23 so as to close the tool insertion gap 28. The upper body 21 closes the tool insertion gap 28 by being detachably engaged with the receiving portion 23, and the tool insertion gap 28 can be opened by removing the upper body 21 from the receiving portion 23. The upper body 21 is formed in a flat plate shape that is approximately the same size as the receiving portion 23, and a hanging portion 29 is formed at the end of the upper body 21 on the connection portion 24 side, which bends downward and is slightly inserted into the tool insertion gap 28. The hanging portion 29 is formed to be approximately equal in length to the tool insertion gap 28 along the connection portion 24. The hanging portion 29 catches in the tool insertion gap 28, which restricts the movement of the upper body 21 in the longitudinal direction of the structural beam 5 and restricts the movement of the upper body 21 toward the floor slab 7. This prevents the movement of the runner material 19 attached to the upper body 21 when the inner wall surface material 10 is screwed in with wall fixing screws 37. The shape of the upper body 21 is not limited to this, and for example, it may have a shape in which a hanging portion is formed on the outer circumference of the upper body 21 to cover the receiving portion 23, or it may have a shape in which a rib is fitted into the tool insertion gap 28 on the lower surface of the upper body 21.

[0028] As shown in Figure 4, the main body 20 and the top body 21 are made of the same material and are in the shape of steel plates, with the top body 21 being thinner than the metal plate forming the main body 20. Runner material 19, which will be described later, is fixed to the top body 21 with screws 31.

[0029] As shown in Figure 1, the upper floor wall base 8 is formed by combining runner material 19 fixed to the upper body 21 with screws 31, studs 30 erected on the runner material 19, and ceiling runner material (not shown), and serves as the base for forming the interior wall surface to which the interior wall material 10 is screwed with wall fixing screws 37. By fixing the runner material 19 and studs 30 to the upper body 21, the weight of these runner material 19 and studs 30 prevents the upper body 21 from coming off the main body 20. The runner material 19 and ceiling runner material are formed in a steel groove shape and face each other. The studs 30 are steel rectangular columns and are erected sandwiched between the runner material 19 and ceiling runner material.

[0030] The fire-resistant covering material 9 is made of a fire-resistant material such as heat-resistant rock wool. The fire-resistant covering material 9 covers the structural beam 5 from below. One end of the fire-resistant covering material 9 abuts against the underside of the floor slab 7 and is wrapped around the side of the structural beam 5, from the underside to the opposite side. The other end of the fire-resistant covering material 9 is inserted between the bottom plate 22 and the receiving portion 23 and is wrapped around up to the top surface of the bottom plate 22.

[0031] In this embodiment, the interior wall panel 10 is a double layer of gypsum board. The interior wall panel 10 is fixed to the runner material 19 and studs 30 of the upper floor wall base 8 with wall fixing screws 37, and is also fixed to the lower floor runner material 15 and lower floor studs 16 of the lower floor wall base 6 with wall fixing screws 37. An atrium 4 connecting the upper and lower floors is provided on the outside of the interior wall panel 10, and the interior wall panel 10 is formed continuously from the upper floor to the lower floor. In addition, wall bases are formed on the upper surface of the floor slab 7 and on the lower flange 12 of the structural beam 5 on the side opposite to the atrium 4, and gypsum board is attached to them, forming the interior walls of the upper and lower floors.

[0032] When constructing the wall structure 2 as described above, first, as shown in Figure 5, the main body 20 of the runner support bracket 1 is fixed to the structural beam 5. The runner support bracket 1 has its upper body 21 removed from the receiving part 23 and stored separately, and the tool insertion gap 28 formed in the receiving part 23 is exposed. The main body 20 is placed on the upper flange 11 of the structural beam 5 so that the connecting part 24 abuts against the side surface of the floor slab 7. At this time, the circular hole formed in the upper flange 11 of the structural beam 5 and the insertion hole 27 formed in the bottom plate 22 of the main body 20 are aligned. Then, the main body 20 and the upper flange 11 are fixed by inserting bolts 25 into the circular hole and insertion hole 27 from below the upper flange 11 and fitting nuts 26 onto the bolts 25 from above the bottom plate 22 and tightening them. Since the tool insertion gap 28 is exposed, the power tool 34 can be inserted from above the main body 20 through the tool insertion gap 28 toward the bottom plate 22, making the tightening of bolts 25 and nuts 26 easier.

[0033] After attaching the main body 20 to the upper flange 11 of the structural beam 5, the fire-resistant covering material 9 is then wrapped around the structural beam 5, as shown in Figure 6, with one end in contact with the lower surface of the floor slab 7 and the other end inserted between the bottom plate 22 and the receiving part 23, and wrapped up to the upper surface of the bottom plate 22. Then, the upper body 21 is attached to the receiving part 23 so that the tool insertion gap 28 is closed.

[0034] Subsequently, as shown in Figure 7, the runner material 19 is placed on the upper body 21 and the bottom surface of the runner material 19 is fixed to the upper body 21 with screws 31. At this time, since the upper body 21 is formed thinner than the main body 20 of the runner receiving bracket 1, the screwing work can be made easier. After that, studs 30 are erected on the runner material 19 to form the upper floor wall base 8, and the interior wall surface material 10 is screwed to the lower floor wall base 6 and the upper floor wall base 8 with wall fixing screws 37 to complete the wall structure 2. In this way, the interior wall surface material 10 is positioned across the runner material 19 that forms the upper floor wall base 8 and the lower floor wall base 6 that is formed below the structural beam 5 and is fixed to each of them, so that the upper and lower wall base materials are connected by the interior wall surface material 10, and the indoor wall surface of the atrium 4 can be firmly formed.

[0035] [Modified example of runner support bracket 1] The runner support fitting 1 is not limited to the one described above. In the above embodiment, the upper body 21 is detachably engaged with the receiving portion 23, but it is not limited to this. In a modified example of the runner support fitting 1, the upper body 21 is slidably fixed to the receiving portion 23, and this sliding motion allows the tool insertion gap 28 formed in the receiving portion 23 of the main body 20 to transition between an open state and a closed state. Specifically, as shown in Figures 8 to 10, the upper body 21 of the runner support fitting 1 has folded-over portions 32 formed on both sides of its edge. The folded-over portions 32 are shaped to allow the side edges 33 of the receiving portion 23 to be inserted, and the upper body 21 is slidable along the side edges 33 of the receiving portion 23. With this type of runner support fitting 1, by sliding the upper body 21, it is possible to transition between a state where the tool insertion gap 28 is closed, as shown in Figure 9, and a state where the tool insertion gap 28 is open, as shown in Figure 10. Therefore, when fixing the runner support fitting 1 to the structural beam 5, as shown in Figure 10, by keeping the tool insertion gap 28 open while a part of the upper body 21 is caught on the receiving part 23, the tool 34 can be inserted into the tool insertion gap 28 to fasten the main body 20 to the structural beam 5, and then the upper body 21, which is partially caught on the receiving part 23, can be slid to close the tool insertion gap 28. This eliminates the need to separately store the upper body 21 during the work, reducing the effort required during construction. Note that the mechanism for making the upper body 21 slidable is not limited to the above configuration, and any shape is acceptable as long as the upper body 21 or the receiving part 23 can slide relative to each other.

[0036] [First modified example of wall structure 2] Note that the wall structure 2 is not limited to the one described above. As shown in Figure 11, the wall structure 2 may also be used to separate two spaces where one side has a normal floor height and the other side has a lower floor height, such as a bathroom. In this wall structure 2, the edge of the first floor slab 35 is placed on one side in the width direction of the upper flange 11 of the structural beam 5 to form a floor of normal height, and the second floor slab 36 is placed at a lower position on the side of the structural beam 5 to form a lower floor. In this floor structure, the interior wall surface material 10 is divided between the upper and lower floors in order to fix the second floor slab 36 to the structural beam 5, but the configuration is the same as in the above embodiment in which the atrium 4 is formed, so a detailed explanation will be omitted.

[0037] [Second modified example of wall structure 2] Furthermore, the wall structure 2 may separate two spaces that have open spaces or low floors on both sides. As shown in Figure 12, in the wall structure 2 that separates two spaces with open spaces on both sides, the floor slab 7 is not fixed to both sides of the structural beam 5, and runner support brackets 1 are fixed with bolts 25 to both sides in the width direction of the upper flange 11 of the structural beam 5. Above and below the structural beam 5, upper floor wall base 8 and lower floor wall base 6 similar to the embodiment described above are formed on both sides of the structural beam 5, and interior wall surface material 10 is attached to these upper floor wall base 8 and lower floor wall base 6 respectively, so that open spaces are formed on both sides of the structural beam 5.

[0038] As described above, the runner support bracket 1 and wall structure 2 of the embodiments and each modified version of the present invention allow the tool insertion gap 28 to be opened and closed, making it easy to fix the main body 20 of the runner support bracket 1 to the structural beam 5 using a power tool 34. Furthermore, the upper body 21 is formed thinly, making it easy to drive screws when fixing the runner material 19, thus reducing the labor required for construction.

[0039] It goes without saying that the embodiments of the present invention are not limited to those described above, and can be modified as appropriate without departing from the scope of the spirit of the present invention.

[0040] This specification discloses the following technologies:

[0041] [Note 1] The runner support fitting described in Appendix 1 is a runner support fitting interposed between a structural beam of a building and a runner material laid on the structural beam to form the base of an interior wall, comprising: a main body having a bottom plate fixed to the upper surface of the structural beam; a receiving portion positioned above the bottom plate at a distance from it and having a tool insertion gap; and a connecting portion connecting the bottom plate and the receiving portion; and an upper body positioned parallel to the bottom plate and on the receiving portion so as to close the tool insertion gap, and which can be moved to a state where the tool insertion gap is open, and on which the runner material is fixed.

[0042] According to the runner support fitting in Appendix 1, the main body comprises a bottom plate, a receiving portion positioned above the bottom plate at a distance, and a connecting portion connecting the bottom plate and the receiving portion. A tool insertion gap is formed in the receiving portion of the main body, and the top body is positioned parallel to the bottom plate to close the tool insertion gap and is formed so as to be able to move into a state where the tool insertion gap is open. By moving the top body to a state where the tool insertion gap is open, a tool can be inserted into the tool insertion gap from above and bolts and nuts can be fastened to fix the runner support fitting to the structural beam. Alternatively, by moving the top body to close the tool insertion gap, the runner material can be screwed onto the top body, thereby reducing the labor required for installation.

[0043] [Note 2] The runner support fitting in Appendix 2 is the same as the runner support fitting in Appendix 1, in which the main body is formed by bending a metal plate, and the upper body is flat and thinner than the metal plate forming the main body.

[0044] According to the runner support bracket described in Appendix 2, the upper body is formed thinner than the metal plate forming the main body. Therefore, the runner support bracket as a whole can be formed with sufficient strength. Furthermore, because the upper body, where the runner material is fixed, is thin, screwing in the runner material becomes easier, thus reducing installation time while maintaining sufficient strength.

[0045] [Note 3] The runner support fitting in Appendix 3 is the runner support fitting in Appendix 2, wherein the upper surface is slidably fixed to the support portion, and this sliding transitions between an open state and a closed state for the tool insertion gap.

[0046] According to the runner support fitting in Appendix 3, the upper body is slidably fixed to the receiving part, allowing the tool insertion gap to transition between open and closed states. Therefore, when fixing the runner support fitting to the structural beam, the tool insertion gap can be opened while a portion of the upper body is hooked onto the receiving part. This allows a tool to be inserted into the tool insertion gap to fasten the main body to the structural beam, and then the upper body, which is partially hooked onto the receiving part, can be slid to close the tool insertion gap. This eliminates the need to separately store the upper body during the work, reducing the effort required during construction.

[0047] [Note 4] The runner support fitting in Appendix 4, in the runner support fitting in Appendix 2, has the upper body detachably engaged with the receiving portion to close the tool insertion gap.

[0048] According to the runner support fitting in Appendix 4, the upper body is detachably engaged with the receiving part. Therefore, when fixing the runner support fitting to the structural beam, the upper body can be removed from the receiving part to open the tool insertion gap, a tool can be inserted into the tool insertion gap to fasten the main body to the structural beam, and then the tool insertion gap can be closed by reattaching the upper body to the receiving part. This allows for a very simple shape and reduces construction time.

[0049] [Note 5] The wall structure described in Appendix 5 is a wall structure formed by fixing the runner material on the runner support brackets described in Appendix 1 to Appendix 4, erecting studs on the runner material to form a wall base, and attaching an interior wall surface material to the wall base, wherein the main body of the runner support bracket is U-shaped in side view, and the end of the fire-resistant covering material that covers at least the side of the structural beam is attached to the upper surface of the bottom plate of the runner support bracket.

[0050] According to the wall structure described in Appendix 5, the main body of the runner support bracket is U-shaped in side view, and the end of the fire-resistant covering material that covers at least the side of the structural beam is attached to the upper surface of the bottom plate of the runner support bracket, so that the fire-resistant covering material can be wrapped up to the upper surface of the structural beam without interfering with the runner support bracket.

[0051] [Note 6] In the wall structure described in Appendix 6, the interior wall surface material is positioned across the runner material and the lower floor wall base formed below the structural beam, and is fixed to each of them.

[0052] According to the wall structure described in Appendix 6, the interior wall panel is positioned across the runner material and the lower floor wall base formed below the structural beam, and fixed to each of them. As a result, the upper and lower wall base materials are connected by the interior wall panel, creating a strong wall structure. [Industrial applicability]

[0053] The runner support bracket and wall structure according to the present invention are suitable as runner support brackets and wall structures used in interior walls such as boundary walls, partition walls, and room dividers. [Explanation of Symbols]
