Abstract
Description
Technical Field
[0001] The present invention relates to a mounting fitting, and more particularly to a mounting fitting used for connecting column members and plate members that constitute a wall base material.
Background Art
[0002] Conventionally, in order to connect plate members and column members that constitute a wall base material of a building, it has been proposed to attach a plate member to a column member by using a plate-shaped mounting fitting (see, for example, Patent Document 1).
[0003] The mounting fitting described in Patent Document 1 includes a substrate (mounting portion) attached to the surfaces of a base reinforcement plate (plate member) and a partition support column (column member), and left and right fitting pieces (extending portions) disposed between the base reinforcement plate and the partition support column. A clamping piece extending parallel to the substrate is continuously provided at the rear end portion of the fitting piece. The substrate has screw holes (threaded holes) formed therein, and the mounting fitting is attached to the partition support column by screwing through the screw holes from the surface of the partition support column. Then, the base reinforcement plate is inserted between the substrate and the clamping piece and screwed from the surface of the base reinforcement plate, whereby the base reinforcement plate is attached to the partition support column.

Summary of the Invention
Problems to be Solved by the Invention
[0005] However, when inserting the base reinforcement plate between the substrate and the clamping piece in a mounting fitting such as that of Patent Document 1, an operator needs to support the base reinforcement plate and the mounting fitting with one hand while screwing, which may reduce workability and mounting accuracy.
[0006] Furthermore, with mounting brackets like the one described in Patent Document 1, the base plate covers the surface of the partition support column, and the screw heads protrude from the surface, which could result in an uneven surface. As a method to suppress surface unevenness, attaching the fitting piece of the mounting bracket to the side of the partition support column makes the work more difficult than screwing it to the partition support column from the surface, potentially reducing work efficiency and installation accuracy. Also, when screwing the fitting piece to the side of the partition support column, the base plate placed on the surface of the partition support column may spring up, potentially causing the mounting bracket to be uneven relative to the partition support column. Furthermore, if the mounting bracket is first attached to the base reinforcement plate, it is not possible to attach the mounting bracket to the side of the partition support column.
[0007] The present invention has been made in view of the above problems, and the object of the present invention is to provide a mounting bracket that can connect column members and plate members with high precision while improving workability. [Means for solving the problem]
[0008] The aforementioned problem is solved by the present invention, which provides a plate-shaped mounting bracket used to connect a column member and a plate member constituting a wall base material, comprising: a first mounting portion that is attached to overlap the surface of the plate member; a second mounting portion that extends from one end of the first mounting portion along the first mounting portion toward the column member and is attached to overlap the surface of the column member; and an extended portion that extends from one end of the first mounting portion toward the plate member in the thickness direction of the plate member and is sandwiched between the plate member and the column member, wherein a notch is formed in the extended portion for bending a part of the extended portion, and by the notch, a part of the extended portion is bent toward the back surface of the plate member, so that a part of the extended portion and the first mounting portion are arranged to sandwich the plate member in the thickness direction of the plate member.
[0009] With the above configuration, the mounting portion of the mounting bracket is attached to the surface of the column member and the plate member, allowing the mounting bracket to be screwed in from the surface of the column member, thus improving workability and mounting accuracy. Furthermore, the upward movement of the mounting portion placed on the surface of the column member can be suppressed, and the mounting bracket can be attached flat to the column member. In addition, the mounting bracket can be attached to the base plate first. Furthermore, since notches are formed in the extended portion, a part of the extended portion can be easily bent at the installation site. Therefore, by bending the extended portion to match the thickness of the plate member and pressing a part of it against the back surface of the plate member, the plate member can be clamped. As a result, the worker can screw it in with their hands free from the base plate and mounting brackets, improving work efficiency and installation accuracy. In addition, it is less bulky than when it is bent from the beginning, making it easy to carry and reducing the space required for transportation and storage.
[0010] In this case, the extended portion has a first extended portion that overlaps the side surface of the plate member and a second extended portion that protrudes beyond the plate member in the thickness direction of the plate member, and a part of the second extended portion is bent toward the back surface of the plate member by the notch formed in the second extended portion, so that a part of the second extended portion and the first mounting portion clamp the plate member in the thickness direction of the plate member, and it is preferable that the contact portion of the part of the second extended portion that abuts against the back surface of the plate member has a sawtooth shape. With the above configuration, the contact portion of the second extension has a sawtooth shape, which suppresses misalignment when the extension is brought into contact with the back surface of the plate member. Therefore, the mounting bracket can more effectively clamp the plate member.
[0011] In this case, the second mounting portion has a stepped portion provided at the base end of the second mounting portion on the side of the first mounting portion, and it is preferable that the stepped portion protrudes from the first mounting portion on the opposite side of the extended portion in the direction in which the extended portion extends. With the above configuration, the mounting portion on the column member side is positioned towards the front due to the stepped base, so that the mounting bracket can be attached flat to the column member and the plate member. To elaborate, generally, steel is used for the column members that make up the wall base material, and plywood is used for the panel members. Therefore, screws are less likely to be fixed to the panel members than to the column members, and the screw heads of the screws attached to the panel members can easily cause the wall base material to become uneven. Therefore, by positioning the first mounting portion on the plate member side, where screws are difficult to secure, towards the rear, the position of the screw heads of the screws attached to each mounting portion can be made flat. As a result, unevenness in the wall substrate caused by the screw heads can be suppressed.
[0012] In this case, the first mounting portion has a screw hole for attaching the plate member, and it is preferable that a raised portion is formed on the periphery of the screw hole, extending outwards from the first mounting portion toward the plate member. With the above configuration, a raised portion is formed on the first mounting portion, which ensures that the screw threads are secured, allowing for firm screw fastening. More specifically, because a raised portion is formed in the screw hole on the plate member side, where screws are more difficult to secure than in the column member, screws can be firmly fastened to the plate member, even though screws are difficult to secure. In other words, screws can be fastened so that the screw head does not protrude from the surface of the plate, thereby suppressing unevenness in the wall base material caused by the screw head. Furthermore, the raised portion created by the burring process provides a stronger grip on the plate member, thus suppressing misalignment.
[0013] In this case, the second mounting portion is preferably formed by cutting and bending a part of the extended portion. With the above configuration, since a portion of the extended part is cut and bent, multiple mounting brackets can be stacked and carried to the installation site. Therefore, multiple mounting brackets can be easily carried in a compact manner, and the space required for transportation and storage can be reduced.
[0014] At this time, the notch is formed in a first edge portion that is an edge portion in a crossing direction intersecting the extending direction of the extending portion among the edge portions of the extending portion. The notch extends from the first edge portion in the crossing direction. In the bent portion when a part of the extending portion is bent by the notch in the extending portion, a folding line for bending a part of the extending portion may be formed. With the above configuration, since the notch is formed in the edge portion of the extending portion, the notch can be easily formed when manufacturing the mounting bracket. Furthermore, by forming the folding line, it can be easily bent at the mounting work site.
[0015] At this time, the notch is formed in a second edge portion that is an edge portion in the extending direction of the extending portion among the edge portions of the extending portion. The notch has a first notch portion extending from the second edge portion in the extending direction and a second notch portion extending from the first notch portion and bending in a direction intersecting the extending direction. In the bent portion when a part of the extending portion is bent by the first notch portion and the second notch portion in the extending portion, a folding line for bending a part of the extending portion may be formed. With the above configuration, since the notch is formed in the edge portion of the extending portion, the notch can be easily formed when manufacturing the mounting bracket. Furthermore, by forming the folding line, it can be easily bent at the mounting work site.
Effect of the Invention
[0016] According to the mounting bracket of the present invention, while enhancing workability, the column member and the plate member can be accurately connected.

MODE FOR CARRYING OUT THE INVENTION
[0018] <First Embodiment> Hereinafter, based on FIGS. 1 to 7, the mounting bracket 1 of an embodiment of the present invention (hereinafter, this embodiment) will be described. In the following description, as shown by the arrows shown in FIG. 1, the “vertical direction” means the vertical direction of the column member S in the erected state. The “left-right direction” means the direction in which the erected column member S and the plate member P are arranged side by side. The “front-back direction” is a direction orthogonal to the vertical direction and the left-right direction, and the front side of the column member S and the front side of the plate member P are the “front side”, and the back side of the column member S and the back side of the plate member P are the “back side”.
[0019] <Mounting Bracket> As shown in FIGS. 1 to 7, the mounting bracket 1 is plate-shaped and is used to connect the column member S and the plate member P that constitute the wall base material. More specifically, the mounting bracket 1 is screwed to the plate member P by a fixing tool B (screw). Then, the mounting bracket 1 screwed to the plate member P is screwed to the column member S by the fixing tool B. By doing so, the column member S and the plate member P are connected by the mounting bracket 1, and the plate surface P1 and the column surface S1 are arranged side by side in the left-right direction, thereby constituting the wall base material.
[0020] As shown in Figure 1, the column member S is a stud (partition column) with a substantially rectangular cross-section. The column members S are arranged on the runner at predetermined intervals when erected. The column member S is, for example, made of metal, and the column surface S1 has an uneven structure formed on it. The column member S may also have a substantially U-shaped cross-section.
[0021] As shown in Figure 1, the plate member P is a plate-shaped base plate (plywood). The plate member P is placed between the column members S, and is attached at a position where the column side S2 of the column member S and the plate side P2 of the plate member P face each other. At this time, the plate surface P1 of the plate member P and the column surface S1 of the column member S are connected in a substantially flush state.
[0022] As shown in Figure 1, the mounting bracket 1 includes a first mounting portion 10 that is attached to the plate surface P1 of the plate member P by overlapping it, a second mounting portion 20 that extends from one end 10a of the first mounting portion 10 along the first mounting portion 10 toward the column member S and is attached to the column surface S1 of the column member S by overlapping it, and an extended portion 30 that extends from one end 10a of the first mounting portion 10 toward the plate member P in the thickness direction of the plate member P and is sandwiched between the plate member P and the column member S. The mounting bracket 1 is formed by punching out a single sheet of metal and then pressing it.
[0023] As shown in Figures 2 and 3, the first mounting portion 10 is a roughly rectangular shape that is elongated in the vertical direction and is attached by overlapping it with the plate surface P1 of the plate member P. The first mounting portion 10 has a plurality of screw holes 11 for attachment to the plate member P. The first mounting portion 10 is attached to the plate member P by being screwed to the plate surface P1 of the plate member P by a fastener B via the screw hole 11.
[0024] The screw hole 11 is formed by burring the first mounting portion 10. By burring, a raised portion 12 is formed on the periphery of the screw hole 11, which rises from the first mounting portion 10 toward the plate member P.
[0025] As shown in Figure 5, the raised portion 12 protrudes from the back surface of the first mounting portion 10 toward the rear at the periphery of the screw hole 11. The formation of the raised portion 12 ensures that even if the first mounting portion 10 is a thin metal plate, the necessary thickness for screw fastening can be secured. In this way, the raised portion 12 is formed by the burring process, which makes it easier for the fastener B to bite into the plate member P. Therefore, the screws can be fastened without the screw heads protruding from the plate surface P1, and unevenness of the wall base material caused by the screw heads can be suppressed. Furthermore, the raised portion 12 formed by the burring process makes the clamping of the plate member P stronger, thus suppressing misalignment.
[0026] As shown in Figures 2 and 3, the second mounting portion 20 is a roughly rectangular shape that is elongated in the vertical direction and is attached by overlapping it with the column surface S1 of the column member S. The second mounting portion 20 has a plurality of fixing holes 21 for attachment to the column member S. The second mounting portion 20 is attached to the column member S by being screwed to the column surface S1 of the column member S by a fastener B via the fixing hole 21.
[0027] The second mounting portion 20 extends from one end 10a of the first mounting portion 10 along the first mounting portion 10 toward the column member S. In other words, the first mounting portion 10 and the second mounting portion 20 are arranged side by side in the left-right direction so that the surfaces of the first mounting portion 10 and the second mounting portion 20 are substantially horizontal.
[0028] Specifically, as shown in Figures 2 and 3, the base end portion 20a of the second mounting portion 20 is continuously provided on the upper and lower right ends of one end portion 10a of the first mounting portion 10. In other words, the second mounting portion 20 is provided on a portion of one end portion 10a of the first mounting portion 10. Therefore, the surface area of the second mounting portion 20 is smaller than that of the surface area of the first mounting portion 10. In this way, by making the surface area of the second mounting portion 20 smaller than the surface area of the first mounting portion 10, it is possible to suppress the second mounting portion 20 from warping upward when it is screwed onto the column surface S1 of the column member S.
[0029] The corners 20b of the second mounting portion 20 are rounded (R-shaped). By rounding the corners 20b of the second mounting portion 20, it is possible to prevent the second mounting portion 20 from warping upward when it is screwed onto the column surface S1 of the column member S. Furthermore, the shape of the corner portion 20b is not limited to rounded edges; for example, it may be chamfered. Also, the shape of the second mounting portion 20 is not limited to a roughly rectangular shape; for example, it may be semicircular. Rounded edges are preferable to prevent bulkiness when stacking and storing the mounting brackets 1 and to suppress warping.
[0030] As shown in Figures 2 and 5, the second mounting portion 20 is formed by cutting and bending a portion of the extended portion 30. Because it is formed by cutting and bending a portion of the extended portion 30 (corresponding to the opening 35 described later), multiple mounting brackets 1 can be stacked and carried to the installation site.
[0031] As shown in Figures 2 and 3, the second mounting portion 20 has a stepped portion 22 provided at the base end portion 20a on the first mounting portion 10 side of the second mounting portion 20. Due to the stepped portion 22, the second mounting portion 20 protrudes from the first mounting portion 10 on the opposite side (front side) from the extended portion 30 in the direction in which the extended portion 30 extends (front-rear direction).
[0032] As shown in Figure 5, the stepped portion 22 is a portion that protrudes forward by a predetermined distance h from the surface of the first mounting portion 10. By forming the stepped portion 22, the first mounting portion 10 on the plate member P side, where the fastener B is difficult to fix (where the screws do not easily bite in), can be positioned behind the second mounting portion 20. Therefore, the positions of the screw heads of the fastener B attached to the first mounting portion 10 and the second mounting portion 20 can be aligned flat.
[0033] As shown in Figures 2, 4, and 5, the extended portion 30 is a roughly rectangular shape that is elongated in the vertical direction and is positioned between the roughly plate member P and the column member S. The extended portion 30 extends from one end 10a of the first mounting portion 10 toward the plate member P side (rear side) in the thickness direction (front-rear direction) of the plate member P. In other words, it is positioned along the gap between the plate side surface P2 of the plate member P and the column side surface S2 of the column member S.
[0034] The extended portion 30 has a first extended portion 31 that overlaps the side surface P2 of the plate member P, and a second extended portion 32 that protrudes rearward from the plate member P in the thickness direction of the plate member P. The extended portion 30 has a notch 33 for bending a part of the extended portion 30, a fold 34 for bending a part of the extended portion 30 (bending piece 32a), and an opening 35 which is the part of the second mounting portion 20 that has been cut up. The notch 33 causes a portion of the extended portion 30 to be bent toward the back surface P3 of the plate member P, so that the portion of the extended portion 30 and the first mounting portion 10 are positioned to sandwich the plate member P in the thickness direction (front-to-back direction) of the plate member P.
[0035] As shown in Figure 4, the notch 33 is formed in the first edge portion 30a of the extended portion 30, which is the edge portion (upper end portion and lower end portion) in the intersecting direction (up and down direction) that intersects with the extending direction (front and back direction) of the extended portion 30. The notches 33 extend in a direction perpendicular to the first edge 30a. Specifically, the upper notch 33 extends perpendicularly to the first edge 30a, downward from the upper first edge 30a, and is formed to a position above the opening 35. The lower notch 33 extends perpendicularly to the first edge 30a, upward from the lower first edge 30a, and is formed to a position below the opening 35.
[0036] As shown in Figure 4, the notch 33 is a slit provided along the boundary between the first extended portion 31 and the second extended portion 32. Note that the shape of the notch 33 is not limited to a slit; it may also be a weak point such as a perforation. As shown in Figure 6, the first extended portion 31 has approximately the same thickness as the plate member P. The notch 33 is provided along the first extended portion 31. Therefore, by simply bending the bent piece 32a of the second extended portion 32 toward the plate member P side using the notch 33 formed in the second extended portion 32, the bent piece 32a can be brought into contact with the back surface P3 of the plate member P.
[0037] In other words, the extended portion 30 is bent towards the back surface P3 of the plate member P by the notch 33 formed in the second extended portion 32, so that the bent piece 32a and the first mounting portion 10 can clamp the plate member P in the thickness direction of the plate member P. Furthermore, the direction in which the notch 33 is formed is not limited to a direction perpendicular to the first edge portion 30a, but may also extend in a direction that diagonally intersects the extending direction of the extended portion 30. By forming the notch 33 diagonally with respect to the vertical direction of the plate member P, the force with which the bent piece 32a presses against the back surface P3 of the plate member P can be increased.
[0038] The contact portion 33a of the bent piece 32a of the second extending portion 32, which abuts against the back surface P3 of the plate member P, has a sawtooth shape. Because the bent piece 32a has a sawtooth shape, misalignment can be suppressed when the bent piece 32a is brought into contact with the back surface P3 of the plate member P. Note that the contact portion 33a is not limited to a sawtooth shape; any shape that can suppress misalignment is acceptable. In addition, the contact portion 33a may be roughened to prevent slippage.
[0039] As shown in Figure 4, the fold line 34 is formed in the folded portion when a part of the extended portion 30 is folded by the cut 33. The fold line 34 can be easily folded by, for example, forming multiple elongated holes that extend along the folded portion. Note that the fold line 34 is not limited to multiple elongated holes, as long as it has a shape that allows for easy folding. For example, it may be a V-shaped groove that extends along the folded portion, or a fragile part such as a perforation.
[0040] <How to install the mounting bracket> Next, the method of connecting the column member S and the plate member P using the mounting bracket 1 will be explained based on Figures 6 and 7.
[0041] As shown in Figure 6, the worker attaches the mounting bracket 1 to the plate member P by screwing it to the plate member P using the fastener B. Specifically, the worker first positions the mounting bracket 1 on the board member P such that the first mounting portion 10 faces the board surface P1 and the extended portion 30 faces the board side P2. In this state, the worker folds the folding piece 32a along the crease 34 so that the contact portion 33a of the extended portion 30 contacts the back surface P3 of the board. In this way, the bent portion 32a of the extended portion 30 and the first mounting portion 10 can clamp the plate member P in the thickness direction of the plate member P.
[0042] The worker fastens the plate member P and the mounting bracket 1 with screws using the fastener B, while the plate member P is held between the bent piece 32a and the first mounting portion 10. In this way, the worker does not need to hold the plate member P or the mounting bracket 1 to prevent the mounting bracket 1 from shifting relative to the plate member P, and can therefore fasten the screws stably with both hands.
[0043] As shown in Figure 7, the worker connects the column member S and the plate member P by screwing the mounting bracket 1, which is screwed to the plate member P, to the column member S using the fixing device B. Specifically, the worker first positions the second mounting portion 20 facing the column surface S1 so that the extended portion 30 is sandwiched between the plate side P2 and the column side S2, and then positions the plate member P and the mounting bracket 1 relative to the column member S. In this state, the worker fastens the column member S and the mounting bracket 1 with screws using the fastener B. In this way, the column member S and the plate member P are connected by the mounting bracket 1 so that the plate surface P1 and the column surface S1 are aligned in the left-right direction.
[0044] With the above-described method of connecting the mounting bracket 1, the column members S and plate members P can be connected with high precision while improving work efficiency, thereby suppressing unevenness in the column members S and plate members P that constitute the wall base material. In this embodiment, the mounting bracket 1 is attached to the plate member P first, and then the mounting bracket 1, which is screwed to the plate member P, is screwed to the column member S to connect the column member S and the plate member P. However, this is not limited to this method. For example, the mounting bracket 1 may be attached to the column member S first, and then the mounting bracket 1, which is screwed to the column member S, is screwed to the plate member P to connect the column member S and the plate member P.
[0045] <Second Embodiment> Next, the mounting bracket 100 of the second embodiment will be described with reference to Figure 8. Note that explanations that overlap with those for Mounting Bracket 1 described above will be omitted. In the mounting bracket 100 of the second embodiment, the configuration of the extended portion 130 is mainly different from that of the mounting bracket 1.
[0046] As shown in Figure 8, the extended portion 130 has a first extended portion 131 that overlaps the side surface P2 of the plate member P, and a second extended portion 132 that protrudes rearward from the plate member P in the thickness direction of the plate member P. The extended portion 130 has a notch 133 for folding a part of the extended portion 130 and a fold line 134 for folding a part of the extended portion 130 (folding piece 132a). The notch 133 causes a portion of the extended portion 130 to be bent toward the back surface P3 of the plate member P.
[0047] As shown in Figure 8, the notch 133 is formed in the second edge portion 130b of the extended portion 130, which is the edge portion in the extending direction (front-to-back direction) of the extended portion 130, among the edges 130a and 130b of the extended portion 130. The notch 133 has a first notch portion 133A that extends in the direction of extension from the second edge portion 130b, and a second notch portion 133B that bends from the first notch portion 133A and extends in a direction intersecting the direction of extension (up and down direction). Specifically, the first notch portion 133A extends perpendicularly to the second edge portion 130b, forward from the second edge portion 130b, and bends upward in the central part of the extended portion 130. The second notch portion 133B extends upward from the first notch portion 133A.
[0048] As shown in Figure 8, the second notch 133B is a slit provided along the boundary between the first extension 131 and the second extension 132. As shown in Figure 8, the first extended portion 131 has approximately the same thickness as the plate member P. The second notch portion 133B is provided along the first extended portion 131. Therefore, by simply bending the bent piece 132a of the second extended portion 132 toward the plate member P, the notch 133 formed in the second extended portion 132 allows the bent piece 132a to come into contact with the back surface P3 of the plate member P.
[0049] In other words, the extended portion 130 is bent towards the back surface P3 of the plate member P by the notch 133 formed in the second extended portion 132, which causes the bent piece 132a of the second extended portion 132 to be bent toward the back surface P3 of the plate member P.
[0050] The contact portion 133a of the bent piece 132a of the second extending portion 132, which abuts against the back surface P3 of the plate member P, has a sawtooth shape. Because the bent piece 132a has a sawtooth shape, misalignment can be suppressed when the bent piece 132a is brought into contact with the back surface P3 of the plate member P.
[0051] As shown in Figure 8, the fold line 134 is formed in the folded portion when a part of the extended portion 130 is folded by the cut 133. The fold line 134 can be easily folded by forming, for example, multiple elongated holes extending along the folded portion.
[0052] <Other Embodiments> The mounting bracket of the present invention is not limited to the embodiments described above. In this embodiment, the case in which a stud is connected as a column member S and a base plate is connected as a plate member P has been described as an example. However, it is not limited to this, and is also suitable for, for example, when connecting a light ceiling base and a base plate to form a ceiling base material for attaching a ceiling board.
[0053] In the above embodiments, the mounting bracket according to the present invention was mainly described. However, the embodiments described above are merely examples to facilitate understanding of the present invention and do not limit it. The present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included. [Explanation of Symbols]
