Description

Technical Field

[0001] The present invention relates to a mounting member for attaching a wall base to a beam of a building.

Background Art

[0002] Conventionally, a mounting member has been used to attach a wall base to a beam that constitutes a structural frame in a building. Patent Document 1 discloses a base material fixing metal fitting having a fitting portion with a cut groove that fits into a flange of a beam made of H-shaped steel, and a support portion connected to the fitting portion and supporting the upper portion of the wall base. The support portion has two abutting pieces facing each other for sandwiching the upper portion of the wall base in the inner and outer directions.

[0003] In the base material fixing metal fitting disclosed in Patent Document 1, since it is necessary to sandwich the upper portion of the wall base in the inner and outer directions between the two abutting pieces, if the fitting portion is fitted to the beam before the wall base is sandwiched by the support portion, it is necessary to move the wall base horizontally with respect to the abutting pieces to sandwich the upper portion of the wall base between the abutting pieces, making the construction of the wall base difficult. Therefore, when attaching the wall base to the beam using the base material fixing metal fitting, it is necessary to fix (support) the wall base to the support portion before fitting the fitting portion to the beam. Thus, with the base material fixing metal fitting and the wall base fixed to each other, the cut groove is applied to the flange of the beam, and the fitting portion is struck toward the beam using a hammer or the like to attach the wall base to the beam.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In buildings, to ensure thermal insulation, a wall substrate is sometimes used that includes a wall frame and insulating material covering the surface of the wall frame. When such a wall substrate is attached to a beam using the substrate fixing bracket described in Patent Document 1, it is necessary to sandwich the wall frame, which is more rigid than the insulating material, between the support parts. In this case, the insulating material on the surface of the wall frame becomes an obstacle when fitting the wall frame into the support parts, making it difficult to attach the substrate fixing bracket to the wall substrate. Furthermore, since the two contact pieces of the support part are fixed at a predetermined interval, it is necessary to prepare a support part that corresponds to the thickness of the wall substrate (wall frame).

[0006] Furthermore, the base material fixing bracket disclosed in Patent Document 1 is attached to the beam while integrated with the wall base, so the force required for attachment is greater compared to when the base material fixing bracket is attached to the beam by itself. As a result, the fitting portion may be damaged by a large reaction force from the beam when it is attached to the beam.

[0007] This invention has been made in view of the above problems, and aims to provide a mounting member for attaching a wall substrate to a beam, which can be easily attached to the wall substrate regardless of the thickness of the wall substrate, and which can suppress damage when attaching to the beam. [Means for solving the problem]

[0008] As a result of various studies, the inventors have found that the above objective can be achieved by the following invention.

[0009] An attachment member according to one aspect of the present invention is an attachment member for attaching a wall base to a beam in a building having a web and a flange extending from the web, interposed between the beam and the wall base, the attachment member comprising: a wall base attachment portion attached to the wall base; and a beam attachment mechanism connected to the wall base attachment portion and attached to the beam by fitting with the flange, wherein the wall base attachment portion has a contact surface that is open toward the other side in the inward / outward direction in order to contact one side of the wall base in the inward / outward direction; and a mounting portion that allows attachment to the wall base from one side in the inward / outward direction while the contact surface is in contact with one side of the wall base.

[0010] According to the above mounting member, the contact surface of the wall substrate mounting portion is open toward the other side in the inward / outward direction of the wall substrate, and the mounting portion allows attachment to the wall substrate from one side in the inward / outward direction. Therefore, with the beam mounting mechanism attached to the beam, the wall substrate can be brought into contact with the contact surface from the other side in the inward / outward direction (the open side), and in this state, the wall substrate can be attached to the mounting portion from one side in the inward / outward direction.

[0011] This allows the mounting part to be attached to the wall substrate from one side of the wall substrate, even if there is insulation material on the other side in the inward / outward direction. Furthermore, since the contact surface of the mounting part is open to the other side in the inward / outward direction, wall substrates of different thicknesses can be attached to this mounting part. In this way, the above mounting member can be easily attached to the wall substrate.

[0012] Furthermore, since the contact surface of the mounting member for the wall substrate is open to the other side in the inward and outward direction of the wall substrate, the wall substrate can be positioned in a predetermined location relative to the beam before attaching the mounting member to the beam, and then the beam mounting mechanism of the mounting member can be fitted to the beam before attaching the wall substrate to the wall substrate mounting part from the other side. As a result, the mounting member can be attached to the beam by itself, and the force required for nailing can be reduced, thus suppressing damage to the mounting member when attaching it to the beam.

[0013] In the above-described mounting member, the beam mounting mechanism comprises a pair of beam mounting plates facing each other in opposing directions perpendicular to the inward and outward directions, each having a groove that opens to one or the other side of the inward and outward directions and has a width dimension into which the flange can be fitted, and at least one of the pair of beam mounting plates has an inclined portion that is inclined with respect to a reference direction perpendicular to the inward and outward directions and the opposing directions so as to approach the other beam mounting plate, and the groove in the beam mounting plate having the inclined portion may be formed in the inclined portion, extend parallel to the thickness direction of the inclined portion and have a pair of inner surfaces facing the reference direction.

[0014] In this embodiment, the mounting members can be securely attached to the beam because a pair of beam mounting plates can be fitted to the beam flange with a gap between them in the opposing direction.

[0015] On the other hand, because a gap is provided between the pair of beam mounting plates, depending on the positional relationship with members (e.g., braces) provided around the flange, there is a risk that the mounting position of the mounting member may be restricted. However, in this embodiment, because a groove is formed in the inclined portion, the gap between the pair of beam mounting plates is narrowed in the portion where the groove is formed, thus improving the degree of freedom in mounting to the flange, which would otherwise be restricted in terms of mounting position.

[0016] Furthermore, a groove is formed in the inclined portion of the beam mounting plate, and since the inner surface of the groove facing the reference direction is parallel to the thickness direction of the inclined portion, the groove and the flange make line contact. Therefore, the beam mounting mechanism can be fitted into the flange with less force compared to when the groove and the flange make surface contact.

[0017] In the above-described mounting member, the beam mounting mechanism may have a deformation restricting mechanism that restricts the deformation of the inclined portion in a direction along the reference direction.

[0018] If a groove is provided in the inclined portion of the beam mounting plate, having an inner surface parallel to the thickness direction of the inclined portion, when the beam mounting mechanism is fitted to the flange, a reaction force is generated that deforms the inclined portion of the beam mounting plate so that the inner surface of the groove aligns with both the front and back surfaces of the flange (so that the inclined portion aligns with the reference direction). When the inclined portion of the beam mounting plate deforms so that the inner surface of the groove aligns with both the front and back surfaces of the flange, the minimum gap of the groove in the reference direction widens, reducing the force with which the beam mounting plate fits to the flange, which may lead to an unstable fixing state of the wall substrate to the beam.

[0019] However, in this embodiment, even if a reaction force is generated in the inclined portion that causes the inner surface of the groove to deform along both the front and back surfaces of the flange, the deformation restricting mechanism can restrict the deformation of the inclined portion, thus allowing the wall base to be stably fixed to the beam.

[0020] In the above-described connecting member, the deformation regulating mechanism may include a connecting portion that connects the pair of beam mounting plates, and an angle maintaining portion that extends across the beam mounting plate and the connecting portion so as to maintain the connection angle between the beam mounting plate and the connecting portion.

[0021] In this embodiment, the connecting portion can suppress changes in the distance between the pair of beam mounting plates, and the angle maintenance portion can maintain the connection angle between the beam mounting plate and the connecting portion. This makes it possible to restrict the deformation of the inclined portion in the direction along the reference direction.

[0022] In the above-described mounting member, the connecting portion connects one end of the pair of beam mounting plates in the inward and outward direction, and the mounting member may also have another connecting portion that connects the ends of the pair of beam mounting plates in the inward and outward direction that are opposite to the ends connected by the connecting portion.

[0023] In this embodiment, the connecting portion and another connecting portion can suppress changes in the distance between the pair of beam mounting plates from both the inward and outward directions. This makes it possible to more reliably restrict deformation of the inclined portion in the direction along the reference direction.

[0024] In the above mounting member, the deformation restricting mechanism may have a reinforcing portion that extends along the inner and outer direction at one edge of the groove portion in the reference direction in the inclined portion and increases the bending rigidity of the inclined portion with respect to the inner and outer direction.

[0025] In this aspect, the reinforcing portion can improve the bending rigidity of the inclined portion, and can suppress the inclined portion from bending and deforming in a direction orthogonal to the inner and outer direction. Thereby, it is possible to restrict the inclined portion from deforming in a direction along the reference direction.

[0026] In the above mounting member, the deformation restricting mechanism may include a restricting member that is detachably attached to the pair of beam mounting plates so as to restrict the inclined portion from deforming in a direction along the reference direction.

[0027] In this aspect, by attaching the restricting member to the beam mounting plate, a function of restricting the inclined portion from deforming in a direction along the reference direction can be added to the beam mounting plate.

Advantages of the Invention

[0028] According to the present invention, it is possible to provide a mounting member that can be easily attached to a wall base regardless of the thickness of the wall base and can suppress breakage when attached to a beam.

[Modes for carrying out the invention]

[0030] (First Embodiment) Hereinafter, a mounting member according to the first embodiment of the present invention will be described with reference to the drawings.

[0031] In this embodiment, the inward / outward direction of the building 1 shown in Figure 1 (the thickness direction of the wall 5) is defined as the first direction X, and the normal direction of the plane of Figure 1 is defined as the second direction Y. The first direction X and the second direction Y are orthogonal. Within the first direction X (inward / outward direction), the rightward direction in Figure 1 (direction from outside to inside) is defined as the +X direction, and the leftward direction (direction from inside to outside) is defined as the -X direction. Within the second direction Y, the depth direction of the plane of Figure 1 is defined as the +Y direction, and the forward direction is defined as the -Y direction. Furthermore, the direction that is orthogonal to both the first direction X and the second direction Y is defined as the third direction Z (reference direction), and within the third direction Z, the upward direction in Figure 1 is defined as the +Z direction, and the downward direction is defined as the -Z direction.

[0032] Figure 1 is a partial cross-sectional view of the area around a beam in a building where the mounting member according to this embodiment is used, and Figure 2 is an enlarged view of the area around the mounting member in Figure 1. Figure 3 is a front view of the mounting member, and Figure 4 is a cross-sectional view taken along line IV-IV in Figure 3.

[0033] Building 1 comprises a structural frame and attached members attached to the structural frame. As shown in Figure 1, the structural frame includes a first beam 2 extending in a first direction X and a second beam 3 (beam) extending in a second direction Y. Both the first beam 2 and the second beam 3 are made of H-shaped steel. Specifically, as shown in Figure 2, the second beam 3 has a web 3a, upper flanges 3b extending from the upper end of the web 3a to both sides in the first direction X, and lower flanges 3c extending from the lower end of the web 3a to both sides in the first direction X. The first beam 2 has a similar configuration.

[0034] The attached components include a ceiling 4 suspended from the first beam 2 via a suspension member (not shown), a wall 5 attached to the second beam 3 and covering the outer perimeter of the building 1, and an attachment member 10 interposed between the wall 5 and the second beam 3 to attach the wall 5 to the second beam 3.

[0035] The ceiling 4 includes a furring strip 4a suspended from the first beam 2, a ceiling board 4b installed below the furring strip 4a, and a fibrous insulation material 4c made of glass wool or the like placed on top of the furring strip 4a and the ceiling board 4b.

[0036] The wall structure 5 comprises an interior wall base 6 (wall base) positioned below the second beam 3, an interior wall panel 7 provided on the interior side (+X direction side) of the interior wall base 6, and an exterior wall panel 8 provided on the exterior side (-X direction side) of the interior wall base 6 and the second beam 3.

[0037] The interior wall substrate 6 comprises an interior wall frame 6a made of a material having higher rigidity than fibrous insulation material (for example, wood), and a fibrous insulation material 6b made of glass wool or the like attached to the -X side of the interior wall frame 6a.

[0038] The mounting member 10 is a member interposed between the second beam 3 and the interior wall base 6 to attach the interior wall base 6 to the second beam 3. The mounting member 10 comprises an interior wall base mounting portion 12 attached to the interior wall base 6, a beam mounting mechanism 14 connected to the interior wall base mounting portion 12 and attached to the lower flange 3c of the second beam 3, and a connecting member 16 that connects the interior wall base mounting portion 12 and the beam mounting mechanism 14 so that their inward and outward positions can be adjusted. The connecting member 16 has a bolt 16a and a nut 16b that screws onto the bolt 16a.

[0039] The interior wall substrate mounting portion 12 includes a mounting portion body 12b that is attached from the inside (+X direction side) to one side (the side facing the +X direction) of the interior wall substrate 6 in the inward-outward direction (first direction X), a connecting portion 12c for connecting the mounting portion body 12b to the beam mounting mechanism 14 so that it can slide inward and outward, a screw 12d for fixing the mounting portion body 12b to the interior wall substrate 6, and a threaded portion 12e that screws into the bolt 16a.

[0040] As shown in Figure 2, the mounting body 12b is a plate-shaped portion arranged along the YZ plane. The mounting body 12b also has a contact surface 12a that is open toward the other side in the inward / outward direction (-X direction) in order to contact one side (the side facing the +X direction) of the inner wall substrate 6 in the inward / outward direction (first direction X), and a mounting body 12b that allows attachment to the inner wall substrate 6 from one side in the inward / outward direction while the contact surface 12a is in contact with one side of the inner wall substrate 6.

[0041] The mounting part body 12b has a plurality of through holes 12b1 that penetrate through the mounting part body 12b in the thickness direction (first direction X). The mounting part body 12b is attached to the inner wall base 6 (inner wall frame 6a) by driving screws 12d into the inner wall base 6 through the through holes 12b1 while the inner wall base 6 (inner wall frame 6a) is in contact with the contact surface 12a from the -X direction side.

[0042] The connected portion 12c has a lower connected portion 12f that extends in the -X direction from the upper end of the mounting portion body 12b and is placed on the inner wall frame 6a, and an upper connected portion 12g provided on the lower connected portion 12f such that a slide groove 12f2 extending in the first direction X is formed between it and the lower connected portion 12f.

[0043] The lower connected portion 12f includes a mounting plate portion (not shown) that is placed on the inner wall frame 6a, and a mounting surface 12f1 that is located in the center of the mounting plate portion in the second direction Y, on the +Z direction side of the upper surface of the mounting plate portion, and extends in the first direction X, to which the upper connected portion 12g is attached.

[0044] The upper connecting portion 12g is attached to the lower connecting portion 12f while resting on the mounting surface 12f1. Since the mounting surface 12f1 is located on the +Z direction side of the upper surface of the mounting plate portion, when the upper connecting portion 12g is attached to the mounting surface 12f1, a slide groove 12f2 is formed between the upper surface of the mounting plate portion and the lower surface of the upper connecting portion 12g, opening in the +Y direction and -Y direction, respectively, and extending in the first direction X.

[0045] The threaded portion 12e extends upward from the -X-direction end of the upper connected portion 12g and is provided with a threaded hole 12e1 into which a bolt 16a can be screwed.

[0046] Next, the beam mounting mechanism 14 will be described. The beam mounting mechanism 14 of this embodiment includes a pair of beam mounting plates 14a facing each other in an opposing direction (second direction Y) perpendicular to the inward-outward direction (first direction X), a deformation restricting mechanism 14b that suppresses deformation of the beam mounting plates 14a, and a sliding part 14c that is slidably fitted into the slide groove 12f2 of the inner wall base mounting part 12.

[0047] Each of the pair of beam mounting plates 14a is inclined in the second direction Y with respect to a reference direction (third direction Z) that is perpendicular to the inward / outward direction (first direction X) and the opposing direction (second direction Y), so that each plate approaches the other beam mounting plate 14a. Specifically, both beam mounting plates 14a are inclined so that their respective upper ends approach each other.

[0048] The pair of beam mounting plates 14a have grooves 14d that open to one side in either the inward or outward direction and have a width dimension that allows the lower flange 3c of the second beam 3 to be fitted. In this embodiment, the grooves 14d open in the -X direction. The grooves 14d extend parallel to the thickness direction of the inclined beam mounting plate 14a and have a pair of inner surfaces 14d1 that face the reference direction. That is, the pair of inner surfaces 14d1 are inclined in a second direction Y with respect to the reference direction according to the inclination angle of the beam mounting plate 14a.

[0049] The deformation regulating mechanism 14b includes a connecting portion 14b1 that connects a pair of beam mounting plates 14a, and an angle maintaining portion 14b2 that extends across the beam mounting plates 14a and the connecting portion 14b1 so as to maintain the connection angle between the beam mounting plates 14a and the connecting portion 14b1.

[0050] In the mounting member 10 of this embodiment, the connecting portion 14b1 connects the +X ends of a pair of beam mounting plates 14a. The connecting portion 14b1 is provided with a through hole 14b3 through which a bolt 16a can be inserted. The bolt 16a is attached to the connecting portion 14b1 in a state where its movement in the X direction is restricted relative to the connecting portion 14b1, and where it can rotate together with the nut 16b. Specifically, the nut 16b is fixed to the threaded portion of the bolt 16a. The nut 16b is fixed to the threaded portion of the bolt 16a with a gap between it and the head of the bolt 16a corresponding to the thickness dimension of the connecting portion 14b1, and the connecting portion 14b1 is positioned in this gap.

[0051] Figure 5 is a cross-sectional view along line VV in Figure 3. As shown in the figure, the angle-maintaining portion 14b2 is provided across the beam mounting plate 14a and the connecting portion 14b1 so as to recess the joint between the beam mounting plate 14a and the connecting portion 14b1 toward the other beam mounting plate 14a. In this embodiment, two angle-maintaining portions 14b2 are provided for each beam mounting plate 14a.

[0052] Figure 6 is a partial cross-sectional view showing a modified example of the angle-maintaining part in the same area as in Figure 5. The angle-maintaining part is not limited to being formed by recessing the joint between the beam mounting plate 14a and the connecting part 14b1 as shown in Figures 2 to 5, but may also be an angle-maintaining part 14b6 formed to connect the connecting part 14b1 and the beam mounting plate 14a, as shown in Figure 6.

[0053] The sliding portion 14c extends in a second direction Y from the lower end of each beam mounting plate 14a toward the other beam mounting plate 14a. Both sliding portions 14c are inserted into the slide grooves 12f2 from both sides in the second direction Y of the mounting surface 12f1 of the lower connected portion 12f. As a result, the beam mounting mechanism 14 is mounted to the inner wall base mounting portion 12 in a state where movement in a third direction Z is restricted, and movement in a first direction X is permitted. In this embodiment, by rotating the bolt 16a in the screw hole 12e1 of the threaded portion 12e, the beam mounting mechanism 14, which follows the bolt 16a, moves in the first direction X relative to the inner wall base mounting portion 12.

[0054] The mounting member 10 is assembled as follows: With the direction in which the groove 14d of the beam mounting plate 14a opens and the direction in which the contact surface 12a of the inner wall base mounting portion 12 faces, the sliding portion 14c of the beam mounting mechanism 14 is inserted into the guide path provided on the upper connected portion 12g of the inner wall base mounting portion 12, thereby combining the beam mounting mechanism 14 and the inner wall base mounting portion 12. As a result, the movement of the beam mounting mechanism 14 in the third direction Z relative to the inner wall base mounting portion 12 is restricted by the lower connected portion 12f and the upper connected portion 12g, and the movement of the beam mounting mechanism 14 in the second direction Y relative to the inner wall base mounting portion 12 is restricted by the slide groove 12f2.

[0055] With the beam mounting mechanism 14 and the inner wall base mounting part 12 assembled, the bolt 16a of the connecting member 16 is inserted through the through hole 14b3 of the connecting part 14b1 and screwed into the nut 16b located on the -X side of the connecting part 14b1. Then, the bolt 16a is inserted into the threaded hole 12e1 of the inner wall base mounting part 12 and screwed into the threaded part 12e. This completes the mounting member 10.

[0056] A method for attaching the interior wall base 6 to the second beam 3 using the mounting member 10 will be explained with reference to Figure 2.

[0057] With the beam mounting plate 14a positioned on the second beam 3 so that the lower flange 3c and groove 14d of the second beam 3 face the first direction X, the beam mounting mechanism 14 (connecting part 14b1) is struck with a hammer or the like. As a result, the beam mounting mechanism 14 fits into the lower flange 3c, and the mounting member 10 is attached to the second beam 3.

[0058] Before or after attaching the mounting member 10 to the second beam 3, the interior wall base 6 is positioned at a predetermined installation location below the second beam 3. The interior wall base 6 has a fibrous insulation material 6b on the -X direction side of the interior wall frame 6a.

[0059] In this state, the inner wall frame 6a is brought into contact with the contact surface 12a of the inner wall base mounting part 12 from the -X direction side, and the mounting part body 12b is attached to the inner wall frame 6a with screws 12d.

[0060] In this embodiment, the mounting member 10 allows the threaded portion 12e of the mounting portion 12 of the mounting part 12 to be moved in the first direction X by rotating the bolt 16a of the connecting member 16 after the mounting part 6 of the mounting part 3 of the mounting part 12

[0061] (Second embodiment) A mounting member according to a second embodiment of the present invention will now be described. In this embodiment, the mounting member 10 is provided with an upper connecting portion 17 and a lower connecting portion 18 (another connecting portion) in addition to the connecting portion 14b1 of the beam mounting mechanism 14 of the mounting member 10 according to the first embodiment.

[0062] Figure 7 is a perspective view of the beam mounting mechanism 14 according to this embodiment. In the following description, components that are substantially the same as those shown in Figures 1 to 4 are denoted by the same reference numerals, and their descriptions are omitted.

[0063] In this embodiment, the pair of beam mounting plates 14a have an upper connecting portion 17 and a lower connecting portion 18 that connect the ends opposite to the ends connected by the connecting portion 14b1 in the inward-outward direction (first direction X) of the beam mounting plates 14a.

[0064] The upper connecting portion 17 connects the ends of the pair of beam mounting plates 14a on the -X side above the groove portion 14d. The lower connecting portion 18 connects the ends of the pair of beam mounting plates 14a on the -X side below the groove portion 14d.

[0065] (Third embodiment) A mounting member according to a third embodiment of the present invention will now be described. The deformation restricting mechanism 14b of the mounting member 10 according to this embodiment has an upper reinforcing portion 14b4 (reinforcing portion) and a lower reinforcing portion 14b5 (reinforcing portion) that extend along the inward and outward direction (first direction X) at both edges of the groove portion 14d of the beam mounting plate 14a in the reference direction (third direction Z), for increasing the bending rigidity of the beam mounting plate 14a in the inward and outward direction.

[0066] Figure 8 is a cross-sectional view of the area around the groove of the beam mounting mechanism 14 according to this embodiment, perpendicular to the first direction X (a cross-sectional view at the position corresponding to the line VIII-VIII in Figure 2). The upper reinforcing portion 14b4 extends in the first direction X at the upper edge of the groove 14d. The upper reinforcing portion 14b4 is formed by recessing the beam mounting plate 14a on which the upper reinforcing portion 14b4 is provided in a direction away from the other beam mounting plate 14a. In this embodiment, the upper reinforcing portion 14b4 is formed by recessing it in a direction away from the other beam mounting plate 14a, but it may also be formed by recessing it in the opposite direction.

[0067] The lower reinforcing portion 14b5 is a plate-shaped member extending in the first direction X, and is fixed to the lower edge of the groove 14d in the beam mounting plate 14a. In this embodiment, the lower reinforcing portion 14b5 is fixed to the side of the beam mounting plate 14a opposite to the other beam mounting plate 14a, but it may also be provided on the side facing the other beam mounting plate 14a.

[0068] The upper reinforcing portion 14b4 and the lower reinforcing portion 14b5 may both be formed by recessing the beam mounting plate 14a, as shown in Figure 8 for the upper reinforcing portion 14b4. Conversely, the upper reinforcing portion 14b4 and the lower reinforcing portion 14b5 may both be formed by plate-shaped members, as shown in Figure 8 for the lower reinforcing portion 14b5.

[0069] Alternatively, only one of the upper reinforcing portion 14b4 or the lower reinforcing portion 14b5 may be provided.

[0070] Furthermore, in the mounting member 10 according to this embodiment, the connecting portion 14b1 and the angle maintenance portion 14b2 described in the first embodiment can be omitted from the deformation restricting mechanism 14b.

[0071] (Fourth embodiment) A mounting member according to a fourth embodiment of the present invention will now be described. The deformation restricting mechanism 14b of the mounting member 10 according to this embodiment includes a restricting member 20 that is detachably attached to a pair of beam mounting plates 14a so as to restrict the inclined beam mounting plate 14a from deforming in a direction along the reference direction (third direction Z).

[0072] Figure 9 is a plan view of the regulating member 20, and Figure 10 is a side view showing the regulating member 20 in use with the mounting member 10. The regulating member 20 has a first mounting portion 21 and a second mounting portion 22, which are respectively placed on the lower inner surface 14d1 of the groove portion 14d so as to span across a pair of beam mounting plates 14a.

[0073] The first mounting portion 21 includes a first main body portion 21a placed on the inner surface 14d1, a first reinforcing portion 21b extending downward from the -X direction end of the first main body portion 21a to increase the bending rigidity of the first main body portion 21a, and a pair of restricting portions 21c that restrict the deformation of each beam mounting plate 14a in the second direction Y when the first main body portion 21a is placed on the inner surface 14d1. The pair of restricting portions 21c each have a pair of claw portions (not shown) extending in the -Z direction from the first main body portion 21a. When the first main body portion 21a is placed on the inner surface 14d1, the pair of claw portions are each positioned on both sides of the beam mounting plate 14a in the second direction Y.

[0074] The second mounting portion 22 is mounted on the inner surface 14d1 and includes a second main body portion 22a connected to the portion between the pair of restricting portions 21c of the first main body portion 21a, and a second reinforcing portion 22b extending upward from the end of the second main body portion 22a opposite to the connection portion with the first mounting portion 21 (+X direction side), which increases the bending rigidity of the second main body portion 22a.

[0075] The restricting member 20 is used when the width of the groove 14d of the beam mounting mechanism 14 is wider than the thickness of the lower flange 3c of the second beam 3, and the mounting member 10 can be used even when the lower flange 3c is thin. In other words, the first main body portion 21a and the second main body portion 22a can fill the gap between the groove 14d and the lower flange 3c.

[0076] In the mounting member 10 according to this embodiment, the connecting portion 14b1 and the angle maintenance portion 14b2 described in the first embodiment can be omitted from the deformation restricting mechanism 14b.

[0077] Alternatively, the restricting member 20 may be inverted from the state shown in Figure 10 and placed on the inner surface 14d1 such that the first reinforcing portion 21b is located on the +X direction side. In this case, since the restricting portion 21c is positioned in the middle of the depth direction of the groove portion 14d, the restricting portion 21c can be used to position the end face of the lower flange 3c of the second beam 3 on the +X direction side. This prevents the beam mounting mechanism 14 from abutting against the web 3a of the second beam 3 when the length of the lower flange 3c in the first direction X is short.

[0078] (Effect, Action) According to the mounting member 10 of each embodiment described above, the contact surface 12a of the inner wall substrate mounting portion 12 is open toward the other side in the inward / outward direction of the inner wall substrate 6, and the mounting portion body 12b allows attachment to the inner wall substrate 6 from one side in the inward / outward direction (first direction X). Therefore, with the beam mounting mechanism 14 attached to a beam (for example, the second beam 3, and so on), the inner wall substrate 6 can be brought into contact with the contact surface 12a from the other side in the inward / outward direction (the open side), and in this state, the inner wall substrate 6 can be attached to the mounting portion body 12b from one side in the inward / outward direction.

[0079] As a result, even if there is a fibrous insulation material 6b or the like on the other side of the interior wall substrate 6 in the inward / outward direction, the interior wall substrate mounting part 12 can be attached to the interior wall substrate 6 from one side of the interior wall substrate 6. Furthermore, since the contact surface 12a of the interior wall substrate mounting part 12 is open to the other side in the inward / outward direction, interior wall substrates 6 of different thicknesses can be attached to this interior wall substrate mounting part 12. In this way, the mounting member 10 according to each of the above embodiments can be easily attached to the interior wall substrate 6.

[0080] Furthermore, in each of the above embodiments, the mounting member 10 has a contact surface 12a of the inner wall base mounting portion 12 that is open to the other side in the inward and outward direction of the inner wall base 6. Therefore, before attaching the mounting member 10 to the beam, the inner wall base 6 can be positioned in a predetermined location relative to the beam, and then the beam mounting mechanism 14 of the mounting member 10 can be fitted to the beam, and the inner wall base 6 can be attached to the inner wall base mounting portion 12 from the other side. As a result, the mounting member 10 can be attached to the beam by itself, and the force required for nailing can be reduced, thus suppressing damage to the mounting member 10 when attaching it to the beam.

[0081] Furthermore, in each of the above embodiments, the mounting member 10 can be fitted to the beam flange (for example, the lower flange 3c of the second beam 3, hereinafter the same) with a gap in the opposing direction (second direction Y) by a pair of beam mounting plates 14a, so that the mounting member 10 can be securely attached to the beam.

[0082] On the other hand, because a gap is provided between the pair of beam mounting plates 14a, depending on the positional relationship with members (e.g., braces) provided around the flange, there is a risk that the mounting position of the mounting member may be restricted. However, in the mounting member 10 according to each of the above embodiments, the entire beam mounting plate 14a is an inclined portion that is inclined with respect to the reference direction (third direction Z). Because a groove 14d is formed in the inclined portion, the gap between the pair of beam mounting plates 14a is narrowed in the portion where the groove 14d is formed, thus improving the degree of freedom in mounting to the flange, which would otherwise be restricted in terms of mounting position.

[0083] Furthermore, a groove 14d is formed in the inclined portion of the beam mounting plate 14a, and the inner surface 14d1 of the groove 14d facing the reference direction (third direction Z) is parallel to the thickness direction of the inclined portion, so the groove 14d and the flange make line contact. Therefore, the beam mounting mechanism 14 can be fitted onto the flange with less force compared to the case where the groove 14d and the flange make surface contact.

[0084] If a groove 14d having an inner surface 14d1 parallel to the thickness direction of the inclined portion is provided in the inclined portion of the beam mounting plate 14a, when the beam mounting mechanism 14 is fitted with the flange, a reaction force is generated in a direction that deforms the inclined portion of the beam mounting plate 14a so that the inner surface 14d1 of the groove 14d follows both the front and back surfaces of the flange. When the inclined portion of the beam mounting plate 14a deforms so that the inner surface 14d1 of the groove 14d follows both the front and back surfaces of the flange (so that the inclined portion follows the reference direction), the minimum gap of the groove 14d in the reference direction widens, reducing the force with which the beam mounting plate 14a fits onto the flange, which may lead to an unstable fixing state of the inner wall base 6 to the beam.

[0085] However, in the mounting member 10 according to each of the above embodiments, even if a reaction force is generated in the inclined beam mounting plate 14a (inclined portion) that causes the inner surface 14d1 of the groove 14d to deform along both the front and back surfaces of the flange, the deformation restricting mechanism 14b can restrict the deformation of the inclined portion, thereby enabling the inner wall base 6 to be stably fixed to the beam.

[0086] In the mounting member 10 according to the first embodiment described above, the connecting portion 14b1 can suppress changes in the distance between the pair of beam mounting plates 14a, and the angle maintenance portion 14b2 can maintain the connection angle between the beam mounting plate 14a and the connecting portion 14b1. This makes it possible to restrict the deformation of the inclined portion in a direction along the reference direction.

[0087] In the mounting member 10 according to the second embodiment described above, the connecting portion 14b1, the upper connecting portion 17, and the lower connecting portion 18 can suppress changes in the distance between the pair of beam mounting plates 14a from both the inward and outward directions. This makes it possible to more reliably restrict the deformation of the inclined beam mounting plate 14a (inclined portion) in the direction along the reference direction.

[0088] In the mounting member 10 according to the third embodiment described above, the upper reinforcing portion 14b4 and the lower reinforcing portion 14b5 can improve the bending rigidity of the inclined beam mounting plate 14a (inclined portion), and can suppress bending deformation of the inclined portion in a direction perpendicular to the inward and outward directions. This can restrict deformation of the inclined portion in a direction along the reference direction.

[0089] In the mounting member 10 according to the fourth embodiment described above, by attaching the restricting member 20 to the beam mounting plate 14a, a function can be added to the beam mounting plate 14a that restricts the deformation of the inclined beam mounting plate 14a (inclined portion) in a direction along the reference direction.

[0090] (modified version) In the embodiments described above, the case was described in which both of the pair of beam mounting plates 14a are inclined with respect to the reference direction (third direction Z). However, neither of the pair of beam mounting plates 14a may be inclined with respect to the reference direction, i.e., they may extend in the reference direction. Also, one of the pair of beam mounting plates 14a may not be inclined with respect to the reference direction, while only the other is inclined with respect to the reference direction. Furthermore, an inclined beam mounting plate 14a does not have to be inclined with respect to the reference direction as a whole, but may have an inclined portion in which a part is inclined with respect to the reference direction. In the case of a beam mounting plate 14a having an inclined portion, the groove 14d is formed in the inclined portion. The groove 14d extends parallel to the thickness direction of the inclined portion and has a pair of inner surfaces facing the reference direction.

[0091] Furthermore, although the above embodiments described a case in which the beam mounting mechanism 14 has a pair of beam mounting plates 14a, the beam mounting mechanism 14 may also have a single beam mounting plate having a certain thickness (for example, the same thickness as the distance between the pair of beam mounting plates 14a).

[0092] Furthermore, in each of the above embodiments, the case in which the connecting portion 14b1 connects a pair of beam mounting plates 14a at the +X end of the beam mounting plate 14a has been described. However, as shown by the dashed line in Figure 7, the connecting portion 14b1 may also connect a pair of beam mounting plates 14a at the intermediate portion of both ends of the beam mounting plate 14a in the first direction X.

[0093] In the embodiments described above, the case in which the connecting portion 14b1 connects the inclined portions of the beam mounting plate 14a has been explained. However, the connecting portion 14b1 may also connect portions other than the inclined portions of the beam mounting plate 14a, or connect inclined portions to portions other than the inclined portions.

[0094] Furthermore, in the second embodiment, as shown in Figure 7, a case was described in which the mounting member 10 has an upper connecting portion 17 and a lower connecting portion 18 in addition to the connecting portion 14b1 and the angle maintaining portion 14b2.

[0095] However, if the mounting member 10 has an upper connecting portion 17 and a lower connecting portion 18, it is possible to restrict the deformation of the inclined portion of the beam mounting plate 14a even without having a connecting portion 14b1 and an angle maintaining portion 14b2. Furthermore, even if only one of the upper connecting portion 17 and the lower connecting portion 18 is present, it is possible to restrict the deformation of the inclined portion of the beam mounting plate 14a. In other words, the beam mounting mechanism 14 may consist of a pair of beam mounting plates 14a and a sliding portion 14c, and only one of the upper connecting portion 17 and the lower connecting portion 18. In this case as well, at least one of the upper reinforcing portion 14b4 and the lower reinforcing portion 14b5 may be provided as the deformation restricting mechanism 14b, or a restricting member 20 may be used.

[0096] The wall substrate to which the mounting member 10 is attached by the beam is not limited to the interior wall substrate 6. For example, in a configuration in which the exterior wall panel 8 is supported by a frame, the object to which the mounting member 10 is attached by the beam may also be the frame.
