Summary of the Invention

Problems to be Solved by the Invention

[0004] When the runner is fixed to the mounting portion of the runner fixing fitting, the runner fixing fitting may be deformed due to a load being applied to the runner fixing fitting. If the runner fixing fitting is deformed, for example, the mounting state of the runner fixing fitting with respect to the lower flange of the steel beam may become unstable.

Means for Solving the Problems

[0005] (1) A runner mounting bracket that solves the above problem is a runner mounting bracket for attaching a runner to a horizontal member having a web extending in the vertical direction, an upper flange provided at the upper end of the web, and a lower flange provided at the lower end of the web, the runner mounting bracket being positioned below the horizontal member and having a horizontal portion and two vertical portions extending downward from the horizontal portion, the runner mounting bracket being positioned between the lower flange and the horizontal portion and having a flat plate-shaped base portion to which the horizontal portion is fixed by a fixing member, and a hook portion that is hooked onto the lower flange, The lower flange has a first hooking portion that hooks onto a portion located on one side of the web, and a second hooking portion that hooks onto a portion located on the other side of the web, wherein the hooking portion has an upright portion extending upward from the base, a mounting portion extending from the upright portion toward the web and resting on the lower flange, and a support portion extending from the upright portion toward the web and extending vertically between the lower flange and the base.

[0006] With this configuration, when the horizontal portion of the runner is fixed to the base of the runner mounting bracket, the support portion braces between the lower flange and the base, thereby suppressing deformation of the hook portion. Therefore, deformation of the runner mounting bracket can be suppressed.

[0007] (2) In the runner mounting bracket of (1) above, the hook portion is formed by bending the portion extending from the base portion, and the hook portion is provided with a through hole that spans from the upright portion to the mounting portion described above. With this configuration, compared to cases where there is no through hole in the hook portion, the portion extending from the base becomes easier to bend, making it easier to form the hook portion.

[0008] (3) In the runner mounting bracket of (2) above, the surface that partitions the through hole has two partition surfaces facing each other in the direction in which the horizontal member extends, and the support portion is composed of a first support piece connected to one of the partition surfaces and a second support piece connected to the other partition surface.

[0009] The through-hole is formed by punching out the hook portion. With the above configuration, the portion punched out when forming the through-hole can be used to form the first support piece and the second support piece.

[0010] (4) In any one of the runner mounting brackets described in (1) to (3) above, one first hooking portion and one second hooking portion are provided. This configuration makes it easier to miniaturize the runner mounting brackets in the direction in which the horizontal member extends, compared to cases where multiple first and second hooking parts are provided. Miniaturizing the runner mounting brackets increases the flexibility of their placement. For example, even if a brace is provided at the end of the horizontal member, the runner mounting brackets are less likely to interfere with the brace, allowing them to be placed at the end of the horizontal member.

[0011] (5) In any one of the runner mounting brackets described in (1) to (4) above, there are two auxiliary support parts that extend upward from the base and are located on both sides of the hooking part in the direction in which the horizontal member extends, and the auxiliary support parts extend vertically between the lower flange and the base.

[0012] With this configuration, when the horizontal portion of the runner is fixed to the base of the runner mounting bracket, the auxiliary support portion braces between the lower flange and the base, thereby suppressing deformation of the base. Consequently, deformation of the runner mounting bracket can be suppressed.

[0013] (6) In any one of the runner mounting brackets described in (1) to (5) above, there are two extensions that extend downward from the base and are positioned on both sides of the runner in directions perpendicular to both the direction in which the horizontal member extends and the vertical direction. This configuration makes it possible to suppress misalignment of the runners relative to the runner mounting brackets in directions perpendicular to both the direction in which the horizontal members extend and the vertical direction.

[0014] (7) A building that solves the above problems comprises a horizontal member having a web extending in the vertical direction, an upper flange provided at the upper end of the web, and a lower flange provided at the lower end of the web; a runner positioned below the horizontal member and having a horizontal portion and two vertical portions extending downward from the horizontal portion; and a runner mounting bracket for attaching the runner to the horizontal member, wherein the runner mounting bracket is one of the runner mounting brackets described in (1) to (6) above.

[0015] With this configuration, when the horizontal portion of the runner is fixed to the base of the runner mounting bracket, the support portion braces between the lower flange and the base, thereby suppressing deformation of the hook portion. Therefore, deformation of the runner mounting bracket can be suppressed. [Effects of the Invention]

[0016] According to the runner mounting bracket and building of this disclosure, deformation of the runner mounting bracket can be suppressed. [Brief explanation of the drawing]

[Figure 3] This is an exploded perspective view showing the beam, runner mounting bracket, and upper runner. [Figure 4] This is a side view of the beam, runner mounting bracket, and upper runner. [Figure 5] This is a cross-sectional view of the beam, runner mounting bracket, and upper runner. [Modes for carrying out the invention]

[0018] Referring to Figures 1 to 5, the runner mounting bracket 16 and the building 10 of this embodiment will be described. As shown in Fig. 1, the building 10 includes a beam 12 as a horizontal member. In the horizontal direction, the direction in which the beam 12 extends is defined as the first direction X, and the direction orthogonal to the first direction X is defined as the second direction Y. The beam 12 of the present embodiment is composed of H-shaped steel. The beam 12 has a web 20 extending in the vertical direction Z, an upper flange 21 provided at the upper end of the web 20, and a lower flange 22 provided at the lower end of the web 20. Of the lower flange 22, the portion located on one side of the web 20 in the second direction Y is defined as the first portion 22a, and the portion located on the other side of the web 20 in the second direction Y is defined as the second portion 22b.

[0019] The building 10 includes a wall base material 13 located below the beam 12. The wall base material 13 is a base material for a partition wall or a boundary wall. The wall base material 13 has an upper runner 14a, a lower runner 14b, and a plurality of studs 15.

[0020] The upper runner 14a and the lower runner 14b each extend in the first direction X. The lower runner 14b is located below the upper runner 14a. The upper runner 14a and the lower runner 14b each have a horizontal portion 40 and two vertical portions 41 extending in the thickness direction of the horizontal portion 40 from both ends of the horizontal portion 40 in the second direction Y. In the upper runner 14a, the two vertical portions 41 extend downward from the horizontal portion 40. In the lower runner 14b, the two vertical portions 41 extend upward from the horizontal portion 40.

[0021] Each stud 15 extends in the vertical direction Z between the upper runner 14a and the lower runner 14b. The plurality of studs 15 are arranged at intervals in the first direction X. The upper end portion of each stud 15 is sandwiched by the two vertical portions 41 of the upper runner 14a. The lower end portion of each stud 15 is sandwiched by the two vertical portions 41 of the lower runner 14b.

[0022] The building structure 10 is equipped with a runner mounting bracket 16 for attaching the upper runner 14a to the beam 12. The runner mounting bracket 16 in this embodiment is formed by bending and punching a single metal plate. The thickness of the metal plate is, for example, 0.5 mm or more and 1.0 mm or less. In the following description, the upper runner 14a will be simply referred to as "runner 14a".

[0023] <Runner mounting bracket> As shown in Figures 2 and 3, the runner mounting bracket 16 is positioned between the beam 12 and the runner 14a. Figure 2 shows the runner mounting bracket 16 after installation. Figure 3 shows the runner mounting bracket 16 before installation.

[0024] The runner mounting bracket 16 has a flat base portion 60. The base portion 60 is positioned between the lower flange 22 of the beam 12 and the horizontal portion 40 of the runner 14a. The upper surface of the base portion 60 faces the lower surface of the lower flange 22. A gap G is provided between the lower surface of the lower flange 22 and the upper surface of the base portion 60. The runner 14a is positioned such that the upper surface of the horizontal portion 40 overlaps the lower surface of the base portion 60.

[0025] As shown in Figures 4 and 5, the horizontal portion 40 of the runner 14a is fixed to the base portion 60 of the runner mounting bracket 16 by screws 17 acting as fixing members. The screws 17 penetrate the horizontal portion 40 and the base portion 60 from below the horizontal portion 40 upwards. The tip of the screw 17 protrudes from the upper surface of the base portion 60. In this embodiment, two screws 17 are provided at each end of the base portion 60 in the second direction Y. The two screws 17 located at each end of the base portion 60 in the second direction Y are located on both sides of the hook portion 61, which will be described later, in the first direction X.

[0026] As shown in Figures 2 and 5, the runner mounting bracket 16 has a hook portion 61 that hooks onto the lower flange 22 of the beam 12. The runner mounting bracket 16 has a first hook portion 61a that hooks onto a first portion 22a of the lower flange 22, and a second hook portion 61b that hooks onto a second portion 22b of the lower flange 22. In this embodiment, one first hook portion 61a and one second hook portion 61b are provided. The runner mounting bracket 16 is suspended from the beam 12 by the first hook portion 61a and the second hook portion 61b hooking onto the lower flange 22.

[0027] The first hook portion 61a and the second hook portion 61b are spaced apart in the second direction Y. The distance between the upright portion 62 (described later) of the first hook portion 61a and the upright portion 62 (described later) of the second hook portion 61b in the second direction Y is slightly larger than the dimension of the lower flange 22 in the second direction Y. In this embodiment, the first hook portion 61a and the second hook portion 61b are located inside both ends of the base portion 60 in the second direction Y. In this embodiment, the distance from the first end of the base portion 60 to the first hook portion 61a in the second direction Y is shorter than the distance from the second end of the base portion 60 to the second hook portion 61b in the second direction Y. The distance from the first end of the base portion 60 to the first hook portion 61a in the second direction Y may be the same as the distance from the second end of the base portion 60 to the second hook portion 61b in the second direction Y.

[0028] In the runner mounting bracket 16 after installation, the hook portion 61 has an upright portion 62, a mounting portion 63, and a support portion 64. The upright portion 62 extends upward from the base portion 60. The lower flange 22 is sandwiched between the upright portion 62 of the first hook portion 61a and the upright portion 62 of the second hook portion 61b.

[0029] The mounting portion 63 extends from the upright portion 62 toward the other hook portion 61. That is, the mounting portion 63 of the first hook portion 61a extends from the upright portion 62 toward the second hook portion 61b. The mounting portion 63 of the second hook portion 61b extends from the upright portion 62 toward the first hook portion 61a. The mounting portion 63 extends from the upright portion 62 toward the web 20 of the beam 12. The mounting portion 63 is mounted on the lower flange 22.

[0030] As shown in Figure 3, in the runner mounting bracket 16 before construction, the hook portion 61 extends upward from the base portion 60. Hereinafter, the hook portion 61 in the state extending upward from the base portion 60 will be referred to as the pre-processing hook portion 61x. The hook portion 61 is formed when the portion of the pre-processing hook portion 61x located above the upper surface of the lower flange 22 is bent during the construction of the runner mounting bracket 16. The erected portion 62 is composed of the portion located on the base end side of the bent position in the pre-processing hook portion 61x. The mounting portion 63 is composed of the portion located on the tip side of the bent position in the pre-processing hook portion 61x.

[0031] The support portion 64 extends from the upright portion 62 toward the other hook portion 61. That is, the support portion 64 of the first hook portion 61a extends from the upright portion 62 toward the second hook portion 61b. The support portion 64 of the second hook portion 61b extends from the upright portion 62 toward the first hook portion 61a.

[0032] As shown in Figures 4 and 5, the support portion 64 extends from the upright portion 62 toward the web 20. The support portion 64 extends vertically in the Z direction between the lower flange 22 and the base 60. Specifically, the support portion 64 of the first hook portion 61a extends vertically in the Z direction between the first portion 22a of the lower flange 22 and the base 60. The support portion 64 of the second hook portion 61b extends vertically in the Z direction between the second portion 22b of the lower flange 22 and the base 60. The dimensions of the support portion 64 in the vertical direction Z are approximately the same as the distance from the lower surface of the lower flange 22 to the upper surface of the base 60 in the vertical direction Z. In this embodiment, the upper surface of the support portion 64 is in contact with the lower surface of the lower flange 22. The lower surface of the support portion 64 is in contact with the upper surface of the base 60.

[0033] As shown in Figures 2 and 4, the hook portion 61 of this embodiment is provided with a through hole 61h. The through hole 61h is provided so as to span from the upright portion 62 to the mounting portion 63. The through hole 61h is formed by punching out the hook portion 61. The surface that demarcates the through hole 61h has two demarcation surfaces 610 facing the first direction X.

[0034] The support portion 64 in this embodiment is composed of a first support piece 64a and a second support piece 64b. The first support piece 64a is connected to one section screen 610. The second support piece 64b is connected to the other section screen 610. The first support piece 64a and the second support piece 64b are perpendicular to the upright portion 62.

[0035] The support pieces 64a and 64b are formed using a portion of the metal plate portion that is punched out to the same shape as the through hole 61h when the metal plate portion that is processed into the hook portion 61 is punched out. In other words, the portion of the metal plate portion that is processed into the hook portion 61 that will later become the support pieces 64a and 64b is punched out in such a way that it is not punched out. After punching, the portion located inside the through hole 61h in the hook portion 61 is bent to form the support pieces 64a and 64b.

[0036] As shown in Figures 3 and 4, the runner mounting bracket 16 of this embodiment has two auxiliary support parts 65. The two auxiliary support parts 65 extend upward from the base 60. The two auxiliary support parts 65 are located on both sides of the first hook part 61a and the second hook part 61b in the first direction X. In this embodiment, the auxiliary support parts 65 are located at both ends of the base 60 in the first direction X. The auxiliary support parts 65 are constructed by bending both ends of a metal plate upward in the first direction X. The dimensions of each auxiliary support part 65 in the vertical direction Z are the same as, or slightly smaller than, the dimensions of the support part 64 in the vertical direction Z. The auxiliary support parts 65 extend in the vertical direction Z between the lower flange 22 and the base 60.

[0037] As shown in Figure 5, the runner mounting bracket 16 of this embodiment has two extensions 66. The two extensions 66 extend downward from the base 60. In this embodiment, the extensions 66 are located at both ends of the base 60 in the second direction Y. The extensions 66 are formed by bending both ends of the metal plate downward in the second direction Y. Each extension 66 is not formed in the portion where the hook portion 61 is provided in the first direction X. The distance between the two extensions 66 in the second direction Y is slightly greater than the dimensions of the runner 14a in the second direction Y. The runner 14a is positioned between the two extensions 66. In other words, the two extensions 66 are positioned on both sides of the runner 14a in the second direction Y. One extension 66 faces one vertical portion 41, and the other extension 66 faces the other vertical portion 41.

[0038] [Operation of this embodiment] The operation of this embodiment will now be explained. The runner mounting bracket 16 is attached to the beam 12 as follows: The runner mounting bracket 16 is positioned below the beam 12 such that the upper surface of the support portion 64 contacts the lower surface of the lower flange 22. Of the pre-processed hook portion 61x, the portion located above the upper surface of the lower flange 22 is bent toward the web 20 and then placed on the lower flange 22. As a result, the hook portion 61 is hooked onto the lower flange 22, and the runner mounting bracket 16 is attached to the beam 12.

[0039] Runner 14a is attached to the runner mounting bracket 16 as follows: Runner 14a is positioned so that the upper surface of its horizontal portion 40 overlaps the lower surface of the base portion 60 of the runner mounting bracket 16. Runner 14a is fixed to the runner mounting bracket 16 by driving screws 17 through from below the runner 14a upwards, passing through both the horizontal portion 40 of the runner 14a and the base portion 60 of the runner mounting bracket 16.

[0040] When the screw 17 is driven in, an upward load is applied to the runner mounting bracket 16. Therefore, if the runner mounting bracket 16 is not provided with a support portion 64 and an auxiliary support portion 65, the runner mounting bracket 16 may deform. Specifically, the runner mounting bracket 16 may deform so that the first hook portion 61a and the second hook portion 61b move apart from each other, or the base portion 60 may bend upward when viewed from the first direction X. In this case, the hook portion 61 may not engage sufficiently with the lower flange 22, which may cause the mounting state of the runner mounting bracket 16 to the beam 12 to become unstable.

[0041] In contrast, the hook portion 61 of the runner mounting bracket 16 in this embodiment has a support portion 64 that extends in the vertical direction Z between the lower flange 22 and the base portion 60. Therefore, when fixing the horizontal portion 40 to the base portion 60, the support portion 64 braces between the lower flange 22 and the base portion 60, thereby suppressing deformation of the hook portion 61 that would cause the first hook portion 61a and the second hook portion 61b to separate from each other. Consequently, it is possible to prevent the mounting state of the runner mounting bracket 16 to the beam 12 from becoming unstable.

[0042] The runner mounting bracket 16 of this embodiment has two auxiliary support parts 65 that extend in the vertical direction Z between the lower flange 22 and the base 60. Therefore, when fixing the horizontal part 40 to the base 60, the auxiliary support parts 65 brace between the lower flange 22 and the base 60, thereby suppressing deformation of the base 60 that would cause it to bend upward when viewed from the first direction X.

[0043] [Effects of this embodiment] The effects of this embodiment will now be explained. (1) The runner mounting bracket 16 has a flat base portion 60, a first hook portion 61a as a hook portion 61, and a second hook portion 61b as a hook portion 61. The base portion 60 is positioned between the lower flange 22 of the beam 12 and the horizontal portion 40 of the runner 14a. The horizontal portion 40 is fixed to the first hook portion 61a by a screw 17. The first hook portion 61a is hooked onto the first portion 22a of the lower flange 22. The second hook portion 61b is hooked onto the second portion 22b of the lower flange 22.

[0044] The hook portion 61 has an upright portion 62, a mounting portion 63, and a support portion 64. The upright portion 62 extends upward from the base portion 60. The mounting portion 63 extends from the upright portion 62 toward the web 20 of the beam 12. The mounting portion 63 is mounted on the lower flange 22. The support portion 64 extends from the upright portion 62 toward the web 20. The support portion 64 extends vertically in the Z direction between the lower flange 22 and the base portion 60.

[0045] With this configuration, when fixing the horizontal portion 40 of the runner 14a to the base portion 60 of the runner mounting bracket 16, the support portion 64 braces between the lower flange 22 and the base portion 60, thereby suppressing deformation of the hook portion 61. Therefore, deformation of the runner mounting bracket 16 can be suppressed.

[0046] (2) The mounting portion 63 is formed by bending the pre-processed hook portion 61x which extends upward from the base portion 60. The hook portion 61 is provided with a through hole 61h that spans from the upright portion 62 to the mounting portion 63.

[0047] With this configuration, compared to the case where the hook portion 61 does not have a through hole 61h, the hook portion 61x before processing becomes easier to bend, making it easier to form the hook portion 61. (3) The surface that demarcates the through hole 61h has two demarcation surfaces 610 facing the first direction X. The support portion 64 is composed of a first support piece 64a connected to one of the demarcation surfaces 610 and a second support piece 64b connected to the other demarcation surface 610.

[0048] The through hole 61h is formed by punching out the hook portion 61. With the above configuration, the portion punched out when forming the through hole 61h can be used to form the first support piece 64a and the second support piece 64b.

[0049] (4) One first hook portion 61a and one second hook portion 61b are provided. This configuration makes it easier to miniaturize the runner mounting bracket 16 in the first direction X compared to the case where multiple first hooking parts 61a and second hooking parts 61b are provided. Miniaturizing the runner mounting bracket 16 increases the degree of freedom in its placement. For example, if a brace is provided at the end of the beam 12, the runner mounting bracket 16 is less likely to interfere with the brace, so the runner mounting bracket 16 can be placed at the end of the beam 12.

[0050] (5) The runner mounting bracket 16 has two auxiliary support parts 65. The two auxiliary support parts 65 extend upward from the base 60 and are located on both sides of the hook part 61 in the first direction X. The auxiliary support parts 65 extend in the vertical direction Z between the lower flange 22 and the base 60.

[0051] With this configuration, when fixing the horizontal portion 40 of the runner 14a to the base portion 60 of the runner mounting bracket 16, the auxiliary support portion 65 braces between the lower flange 22 and the base portion 60, thereby suppressing deformation of the base portion 60. Therefore, deformation of the runner mounting bracket 16 can be suppressed.

[0052] (6) The runner mounting bracket 16 has two extensions 66. The two extensions 66 extend downward from the base 60 and are positioned on both sides of the runner 14a in the second direction Y.

[0053] This configuration makes it possible to suppress misalignment of the runner 14a relative to the runner mounting bracket 16 in the second direction Y. (7) As a method for fixing the runner 14a to the runner mounting bracket 16, for example, screws can be driven in from both sides of the runner mounting bracket 16 so as to penetrate the extended portion 66 of the runner mounting bracket 16 and the vertical portion 41 of the runner 14a. However, in this case, the tip of the screw protrudes from the inner surface of the vertical portion 41 of the runner 14a. Therefore, when sliding the stud 15 in the first direction X between the upper runner 14a and the lower runner 14b in order to adjust the position of the stud 15 in the first direction X, the screw gets in the way.

[0054] In contrast, in this embodiment, the runner 14a is fixed to the runner mounting bracket 16 by driving a screw 17 through the horizontal portion 40 of the runner 14a and the base portion 60 of the runner mounting bracket 16, from below the runner 14a upwards. In this case, the screw 17 does not protrude from the inner surface of the vertical portion 41 of the runner 14a. Also, the amount of protrusion of the screw 17 from the lower surface of the horizontal portion 40 of the runner 14a is very small. Therefore, when sliding the stud 15 in the first direction X between the upper runner 14a and the lower runner 14b, the screw 17 is less likely to get in the way. Consequently, the position adjustment of the stud 15 in the first direction X becomes easier.

[0055] In particular, when the dimensions of the wall in the first direction X are small, it may be necessary to slide the stud 15 through the runner mounting bracket 16 when sliding it in the first direction X, or to position the stud 15 at the location where the runner mounting bracket 16 is provided. For this reason, if the tip of the screw protrudes from the inner surface of the vertical portion 41 of the runner 14a, when sliding the stud 15 to pass through the runner mounting bracket 16, it is necessary to remove the screw, slide the stud 15, and then re-drive the screw. Also, if the tip of the screw protrudes from the inner surface of the vertical portion 41 of the runner 14a, it is not possible to position the stud 15 at the location where the runner mounting bracket 16 is provided. Therefore, the fixing method of this embodiment is particularly effective when the dimensions of the wall in the first direction X are small.

[0056] (8) As a method to suppress deformation of the runner mounting bracket 16, for example, the thickness of the metal plate can be increased, but in this case it becomes difficult to drive in the screws 17. In contrast, in this embodiment, deformation of the runner mounting bracket 16 can be suppressed without increasing the thickness of the metal plate, so it does not become difficult to drive in the screws 17.

[0057] (9) As described above, when the runner mounting bracket 16 is attached to the beam 12, the runner mounting bracket 16 is positioned below the beam 12 such that the upper surface of the support portion 64 contacts the lower surface of the lower flange 22. Therefore, the dimensions of the gap G between the lower surface of the lower flange 22 and the upper surface of the base portion 60 are determined by the dimensions of the support portion 64 in the vertical direction Z. In other words, the support portion 64 not only suppresses deformation of the hook portion 61 but also has the effect of positioning the base portion 60 in the vertical direction Z relative to the lower flange 22.

[0058] <Example of changes> The above embodiments are illustrative of possible forms of the runner mounting bracket 16 and the building 10, and are not intended to limit their form. The runner mounting bracket 16 and the building 10 may take forms different from those illustrated in the above embodiments. Examples include forms in which some of the configurations of the embodiments are replaced, modified, or omitted, or forms in which new configurations are added to the embodiments. Modifications of the embodiments are shown below.

[0059] The horizontal members are not limited to beams 12. The horizontal members may also be girders. The fixing member for securing the horizontal portion 40 of the runner 14a to the base portion 60 of the runner mounting bracket 16 is not limited to a screw 17.

[0060] The hook portion 61 does not necessarily have to have a through hole 61h that spans from the upright portion 62 to the mounting portion 63. Even in this case, at least the effect (1) of the above embodiment can be obtained. The configuration of the support section 64 may be changed as appropriate.

[0061] For example, if the hook portion 61 does not have a through hole 61h, the support portion 64 may extend from the center of the upright portion 62 in the first direction X toward the web 20.
