Description

  The present invention relates to a mounting aid for mounting a wall panel such as an extruded cement board or a lightweight cellular concrete board to a base material of a building, and a wall structure using the same.

  2. Description of the Related Art Conventionally, dry-type wall panels such as an extruded cement board and a lightweight cellular concrete board have been widely used in buildings due to demands for reducing the weight of a building body and increasing the efficiency of construction. For example, when an extruded cement board is attached to a building, a base material attached to a building body (“base material” in the specification and the claims) has a predetermined thickness, (Including a plate-like material, a shaped steel material, and the like) extending in the short direction with the short dimension of (i.e., the lengthwise direction of the extruded cement plate). ing.

  The Z-clip is attached to the extruded cement plate with bolts. However, after being subjected to vibration, earthquake, wind pressure, or the like for a long time after the application, stress is applied, and the axial force of the bolts may be weakened.

  Therefore, in order to prevent the Z-clip from rotating after construction, it is necessary to weld the Z-clip on the upper side of the extruded cement plate to the base material for vertical tension, and to weld all the Z-clips to the base material for horizontal tension. Is being done. However, when welding the Z clip and the base material, time and labor are required. Moreover, when the welded portion of the Z-clip is located in the beam structure, welding may be performed by the sense of a welder, which takes a lot of trouble in construction and causes an increase in cost.

  In addition, as a mounting bracket for preventing rotation without performing welding, a W clip having a wide bracket and two bolt portions may be used. However, due to the structure of the W clip, the unit price of the clip is high, and the cost of the wall panel increases.

  Therefore, as a prior art for preventing the rotation of the Z-clip, an elastic piece is formed at one end of a thin plate-shaped main body, and a locking piece is formed at the other end. There is an anti-rotation plate provided with a rotation-preventing piece that can be bent to face (for example, see Patent Document 1). In this rotation preventing plate, a base material (angle material) is fitted between the elastic piece and the locking piece, and the rotation preventing pieces are bent toward the main body side and positioned on both sides of the Z clip, so that the bolt of the Z clip is provided. Prevents rotation around.

  Further, as another prior art, a base material is sandwiched between holding portions, and fastening portions slightly protruding from the base material are positioned on both sides of the Z clip so that rotation of the Z clip around a bolt is prevented. There is also a mounting aid that has been used (for example, see Patent Document 2).

JP 2003-74166 A JP 2013-28999 A

  However, in Patent Literature 1, the rotation preventing pieces provided at one end of the thin plate-shaped main body are each bent at the site to prevent the rotation of the Z clip. For this reason, although rotation during normal times can be effectively prevented, when a strong force acts on the Z-clip due to, for example, a displacement during an earthquake, the rotation preventing piece is deformed to prevent rotation. Function may be lost.

  Further, in the above-mentioned Patent Document 2, since the thickness direction of the base material is sandwiched by the holding portion of the auxiliary tool and closely adhered, it takes time to insert the base material into the base material, and the workability is deteriorated, resulting in poor workability and time and labor. May be required.

  Therefore, an object of the present invention is to provide a wall panel mounting aid capable of preventing a mounting member of a wall panel from rotating and improving workability at the time of mounting, and a wall structure using the same. .

  In order to achieve the above object, a wall panel mounting aid according to the present invention includes a wall mounted between a mounting member of a wall panel mounted on a base material extending in a longitudinal direction with a predetermined short dimension and the base material. A panel mounting aid, having a predetermined thickness, a plate-shaped member that is in contact with the wall panel, and protruding from the plate-shaped member toward both short-side end portions of the base material in a short direction of the base material. A clamping member that clamps the mounting member from both ends, the clamping member is engaged with one end with a gap in the thickness direction of the base material, and the mounting member is positioned on both sides of the mounting member. An engagement member that prevents rotation of the base material, and an engagement member that is locked to the other end of the base material and that sandwiches the short direction of the base material from both ends with the engagement member. . The term "short direction of the base material" in the specification and the claims refers to a direction in which the length direction of the continuously extending base material is a long direction and is orthogonal to the long direction.

  With this configuration, according to the holding member that sandwiches the short direction of the base material from both ends, one engaging member having a gap in the thickness direction of the base material can easily engage with the base material, and the other locking member Can be easily mounted on the base material, and the mounting member of the wall panel can be prevented from rotating by the engaging member after mounting. Therefore, it is possible to provide a wall panel attachment aid that can prevent rotation of the attachment member of the wall panel and can enhance workability at the time of attachment.

  The engaging member includes an engaging portion that engages with one end of the base material in a state where there is a gap in a thickness direction of the base material, and rotation prevention that extends from the engaging portion in a short direction of the base material. May be included. According to this structure, the engaging member can be easily engaged by being hooked on the base material, and the rotation preventing portion extending in the short direction of the base material from the engaging portion of the engaging member allows the mounting member of the wall panel to be attached. Can be prevented from rotating.

  Further, the locking member may be configured such that a distance between an engaging portion of the engaging member that engages with the base material and a portion of the locking member that locks the base material can be adjusted. Good. With this configuration, even when the short dimension of the base material is different, the distance between the engaging portion of the engaging member that engages with the base material and the portion that locks the locking member with the base material is adjusted. As long as the distance between the locking members can be adjusted, it can be used for a base material having a different short dimension. Therefore, even in a building in which a plurality of types of base materials having different short-dimensions are used, the same wall panel mounting aid can be used.

  Further, the plate-shaped member may further include a spacer member that protrudes from the plate-shaped member in a direction in which the holding member protrudes, and maintains a space between the wall panel and the base material. With this configuration, even when the wall panel is attached at a predetermined interval to the base material, the space between the base material and the wall panel can be stably maintained by the spacer member. Even if such a situation occurs, the distance between the wall panel and the base material can be appropriately maintained.

  Further, the plate-like member and the holding member may be formed as an integral body formed by bending a part of a metal plate. With such a configuration, the wall panel mounting aid can be easily manufactured by punching, bending, or the like of a metal plate, and the manufacturing time and manufacturing cost of the wall panel mounting aid can be reduced.

  On the other hand, the wall structure according to the present invention is a wall structure using any one of the wall panel mounting aids, wherein the base material at a position where the mounting member of the wall panel is mounted has a short direction of the base material. The engaging member of the holding member is engaged with one end of the holding member, and the locking member of the holding member is locked with the other end of the base material. The wall panel mounting aid is mounted so as to be held by a holding member, and the wall panel mounting member is mounted so as to be located between the engaging members of the wall panel mounting aid.

According to this configuration, the holding member of the wall panel mounting aid can easily engage one of the engaging members with the base material, and lock the other locking member with the base material. The mounting aid can be easily attached to the base material, and the mounting member of the panel can be prevented from rotating by the engaging member of the mounted wall panel mounting aid.
Therefore, it is possible to provide a wall structure in which the workability of mounting the wall panel mounting aid on the base material is good, and after mounting, rotation of the mounting member of the wall panel can be prevented for a long period of time.

  ADVANTAGE OF THE INVENTION According to this invention, it can mount | wear easily so that the short direction of a base material may be pinched from both ends, and the operability at the time of mounting can be improved, and the mounting member of a wall panel rotates after mounting. This makes it possible to provide a wall panel mounting aid that can prevent such a situation for a long period of time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiment, an angle material of a shaped steel material will be described as an example of the base material 50. Further, an extruded cement plate will be described as an example of the wall panel 60, and a Z-clip 61 will be described as an example of a mounting member of the wall panel 60. Further, an example will be described in which the wall panel attachment aids 1 and 2 in the following embodiments include a spacer member 17 that holds the wall panel 60 at a predetermined interval T with respect to the base material 50.

  As shown in FIG. 1, the wall panel attachment aid 1 according to the first embodiment includes a plate member 10 in contact with a wall panel 60 (FIG. 3) and a short direction of the base material 50 from the plate member 10 (see FIG. 1). (Upper and lower directions of the drawing), and a holding member 11 that sandwiches the short direction of the base material 50 from both ends (up and down directions in the figure). The holding member 11 includes an engagement member 12 that engages with one short end (upper part in the figure) of the base material 50 and a locking member 15 that is locked with the other end (lower part in the figure) of the base material 50. And

  The engaging member 12 protrudes from one end of the plate-shaped member 10 toward the base material 50 so as to engage with the base material 50 with a gap S in the thickness direction of the base material 50, and a predetermined gap S between the base material 50 and the base material 50. Are formed in such a manner as to bend in a direction parallel to the plate-shaped member 10 at the position having the above, and to extend in the short direction of the base material 50. The engagement member 12 is formed large so as to have a gap S in the thickness direction of the base material 50, so that there is a clearance when the engagement member 12 is engaged with the base material 50. A portion of the engaging member 12 protruding from the plate-like member 10 is an engaging portion 13, and a formed portion extending from the engaging portion 13 in the short direction of the base material 50 is a rotation preventing portion 14. . As described later, the rotation preventing portions 14 are located on both sides of the Z clip (mounting member) 61 (FIG. 4) of the wall panel 60, and are arranged to prevent the rotation of the Z clip 61.

  On the other hand, a locking member 15 projecting from the other end of the plate-shaped member 10 to the base material 50 side is provided so as to face the above-mentioned engaging member 12, and is provided between the engaging member 12 and the locking member 15. The distance H between them is slightly smaller than the short dimension of the base material 50 (in the figure, the state before mounting on the base material 50 is indicated by a solid line). The locking member 15 is provided so as to protrude at a predetermined width from both ends in the longitudinal direction of the base material 50 at the other end of the plate-shaped member 10, and extends from the plate-shaped member 10 toward the engagement member 12. A bent portion 16 is provided, which projects obliquely and bends toward the side opposite to the engaging member. The provision of the bent portion 16 serves as a guide when the locking member 15 is locked to the base material 50. By forming the locking member 15 in this manner, the locking member 15 has a spring property that can be slightly displaced in a direction in which the distance from the engaging member 12 changes.

  Further, the plate member 10 is provided with a spacer member 17 projecting from the plate member 10 in the projecting direction of the sandwiching member 11 and maintaining a space T between the wall panel 60 and the base material 50. The spacer member 17 has a configuration in which a part of the plate member 10 is protruded in the direction in which the holding member 11 protrudes. By forming a spacer member 17 by plastically deforming a part of the plate member 10, the spacer member 17 is integrated with the plate member 10 without using another member as the spacer member 17.

  As such a wall panel attachment aid 1, for example, a flat plate-shaped base material (a plate material before performing bending or the like) is punched from a flat metal plate (for example, a plate thickness of 1 to 2 mm), and the flat plate is formed. Manufacturing the wall panel mounting aid 1 by forming the spacer member 17 of a base material by projecting with a press and bending the engaging member 12 and the locking member 15 by bending. Can be. The end deformation of the plate member 10 between the illustrated engaging members 12 and between the locking members 15 is a material deformation caused by plastically deforming the spacer member 17 by press working. By manufacturing the wall panel mounting aid 1 made of a hard metal plate in this way, compared to a configuration in which a plurality of members are integrated by welding or the like, manufacturing time and manufacturing cost are reduced, and production efficiency is improved. Can be achieved.

  According to such a wall panel mounting auxiliary tool 1, the gap S between the engaging member 12 and the spacer member 17 of the wall panel mounting auxiliary tool 1 is formed to be larger than the thickness of the base material 50, and Since a margin is provided in the direction, the engagement member 12 can be easily engaged with the base material 50. Further, after the engaging member 12 is engaged with one end of the base material 50 in the short direction, the locking member 15 is locked with the other end of the base material 50, so that the spring property of the locking member 15 is improved. In addition, the short direction of the base material 50 is sandwiched from both ends by the engaging member 12 and the locking member 15 so that the base material 50 can be easily mounted on the base material 50. Moreover, when the base material 50 is held in the short direction, the elasticity of the locking member 15 allows the base material 50 to be held firmly.

[Second embodiment]
Drawing 2 is a figure showing wall panel attachment auxiliary equipment 2 concerning a 2nd embodiment, (A) is a front view and (B) is a side view. The wall panel attachment aid 2 of the second embodiment is different from the wall panel attachment aid 1 of the first embodiment only in the configuration of the locking member 15, but is otherwise the same. The same components have the same reference characters allotted, and detailed description thereof will not be repeated.

  As shown in the figure, the locking member 25 of the wall panel mounting aid 2 in the second embodiment is bent largely from the plate member 10 in the direction of the engaging member 12 and projects obliquely, and has a long length. Have been. The distal end is provided with a bent portion 26 bent toward the opposite side of the engagement member. The width dimension of the locking member 25 is the same as that of the first embodiment. By forming the locking member 25 to be greatly bent in this manner, the locking member 25 can be largely displaced in a direction in which the locking member 25 approaches or separates from the engagement member 12. Further, like the first embodiment, the locking member 25 has a spring property that can be slightly displaced in a direction in which the distance from the engaging member 12 changes.

  According to the wall panel mounting aid 2 of this embodiment, as shown by the two-dot chain line, when the base material 50 is small, the state of the locking member 25 can be used at a distance H1 indicated by a solid line in the drawing. The short side direction of the base material 50 is sandwiched between the engaging member 12 and the locking member 25, and the sandwiched state can be maintained with a little elasticity.

  When the base material 51 is large, if the angle of the locking member 25 is adjusted as shown by a two-dot chain line and used as the distance H2, the engagement member 12 and the locking member 25 The pinch can be held in the short direction and held with a little elasticity. When the angle of the locking member 25 of the wall panel mounting aid 2 is changed, the distance between the locking member 25 and the engaging member 12 is adjusted to be slightly smaller than the short dimension of the base material 51 before use (shown by a solid line in the figure). Status). Also in the second embodiment, the engaging member 12 and the locking member 25 are formed as a single body by bending a part of the metal plate together with the plate member 10 by bending, as in the first embodiment. can do.

  Therefore, according to the wall panel mounting aid 2 of the second embodiment, the distance H1 (H2) between the engaging member 12 and the locking member 25 can be adjusted according to the short dimension of the base materials 50 and 51. In addition, when the short direction of the base material 50 is sandwiched between the engaging member 12 and the locking member 25, the state in which the base material 50 is held by the elasticity of the locking member 25 can be maintained. The adjustment of the distance between the engaging member 12 and the locking member 25 can be applied not only to the two types of base materials 50 and 51 shown in the figure but also to a base material having an intermediate size.

  Therefore, in a building in which the base materials 50 of different sizes are used, the work can be performed by a small number of types of wall panel attachment aids 2 when forming the wall structure 30. Therefore, it is possible to reduce the cost required for the wall panel mounting aid 2 and improve the work efficiency.

[Use condition of wall panel mounting aid]
FIG. 3 is a side view showing a use state of the wall panel attachment aid 1 shown in FIG. 1, and FIG. 4 is a front view of the wall panel attachment aid 1 in use. In FIG. 4, the building 70 is shown at a position excluding the configuration (beam 71). In these drawings, when the wall panel 60 is stretched vertically, an example in which the Z-clip 61 is attached to the base material 50 at the vertical position of the wall panel 60 will be described.

  As shown in FIG. 3, a base material 50 is fixed to a beam 71 of a building 70, and the base material 50 is provided so as to be integrated with the beam 71 by welding or the like. The engaging member 12 of the wall panel mounting aid 1 is engaged from the upper end of the base material 50, and the locking member 15 is locked to the lower end of the base material 50. As a result, the wall panel mounting aid 1 is mounted with the short end of the base material 50 sandwiched between the engaging member 12 and the locking member 15 from above and below. In the mounted state, the spacer member 17 comes into contact with the base material 50.

  Then, as shown in FIGS. 3 and 4, the Z clip 61 of the wall panel 60 is attached to the base material 50 on which the wall panel attachment aid 1 is attached. The Z clips 61 are mounted between the engaging members 12 so that the engaging members 12 of the wall panel mounting aid 1 are located on both sides. The illustrated wall structure 30 is an example in which a wall panel 60 is vertically stretched.

  Thus, even if the Z clip 61 attached to the base material 50 at the position where the wall panel attachment aid 1 is mounted is inclined about the attachment bolt 63, the engagement member 12 of the wall panel attachment aid 1 is inclined. (FIG. 4).

  Therefore, after the wall panel 60 is installed, even if the axial force of the mounting bolt 63 fixing the Z clip 61 to the wall panel 60 is weakened by receiving vibration, earthquake, wind pressure, or the like for a long period of time, the Z clip 61 will By tilting only between the engaging members 12 of the panel mounting aid 1 (two-dot chain line shown in FIG. 4), the state of being attached to the base material 50 can be maintained. This makes it possible to stably maintain the state in which the wall panel 60 is attached for a long period of time.

  A packing material 64 is provided between the illustrated wall panel 60 and the wall panel 60 provided below.

[Example of wall structure]
FIG. 5 is a perspective view showing a wall structure 30 provided with the wall panel attachment auxiliary tool 1 shown in FIG. 1, and is an example in which a wall panel 60 is attached in a horizontal state. In this figure, the beams of the building are not shown. The base material 50 fixed to a beam (not shown) is provided so as to extend in the vertical direction. This base material 50 is also an L-shaped steel material.

  The wall panel mounting aid 1 is attached to the base material 50 at a predetermined position. The mounting method of the wall panel mounting aid 1 is the same as that of the first embodiment except that the mounting direction is different by 90 °, and the description is omitted.

  When the wall panel 60 is mounted, the wall panel 60 is mounted so that the Z clip 61 is inserted between the engaging members 12 of the wall panel mounting aid 1. As described above, the wall panel 60 attached to the base material 50 maintains the state where the Z clip 61 is inserted between the engaging members 12. That is, since the wall panel mounting aid 1 is sandwiched by sandwiching the short-side end of the base material 50 from both ends (left and right directions), even when welding is not performed by the horizontal stretching method, the wall panel is not affected by an earthquake or the like. Even if the panel 60 is displaced, the rotation of the Z clip 61 can be prevented by the engagement member 12, so that the mounting state of the wall panel 60 can be maintained. In addition, since the spacer member 17 is provided integrally, the arrangement position of the wall panel 60 by the spacer member 17 can be maintained.

[Summary]
As described above, according to the wall panel mounting aids 1 and 2, the engaging member 12 having the gap S in the thickness direction of the base material 50 can be easily engaged with the base material 50, and the other member If the stop member 15 is locked to the base material 50, the wall panel mounting aids 1 and 2 can be easily mounted on the base material 50. Then, the Z-clip (mounting member) 61 of the wall panel 60 can be prevented from rotating around the mounting bolt 63 by the engaging members 12 of the wall panel mounting aids 1 and 2 after mounting. Therefore, it is possible to provide the wall panel mounting aids 1 and 2 which can enhance the workability at the time of mounting and can prevent the Z clip (mounting member) 61 of the wall panel 60 from rotating after mounting. Become.

  Further, according to the wall panel mounting aids 1 and 2, the base material 50 is attached while sandwiching both ends in the short direction, so that the vertical base material 50 and the horizontal base material 50 can be similarly mounted. It can be used regardless of how the wall panel 60 is stretched. In particular, in the case of horizontal stretching, the wall panel mounting aids 1 and 2 can be appropriately fixed without being temporarily fixed at a predetermined position, so that workability is improved.

  In addition, the distance H between the locking member 25 and the engaging member 12 can be adjusted so that the locking member 25 can be mounted even when the size of the base material 50 is different. It is possible to eliminate the need for the mounting aid 2. Therefore, even in the case of the wall structure 30 using a plurality of types of base materials 50, one type of wall panel mounting aid 2 can be used, and workability is improved as compared with a case where a plurality of types of wall panel mounting aids are properly used. And productivity can be improved.

  In addition, according to the wall panel mounting aids 1 and 2, even in a discontinuous portion (for example, a diaphragm portion) where the base material 50 changes from an L-shaped steel material to an I-shaped steel material, the short length of the I-shaped steel material is reduced. Mounting can be performed by sandwiching the direction (height direction) from both ends, and it can be applied to different base materials 50.

  Further, since the Z clip (mounting member) 61 of the wall panel 60 is not welded to the base material 50, the Z clip 61 can be displaced at the interface with the base material 50 during an earthquake. For this reason, even if displacement occurs in the wall panel 60 due to an earthquake or the like, a large stress does not occur in the wall panel 60. That is, the displacement force at the interface between the Z-clip 61 and the base material 50 can be displaced smaller than the displacement force between the mounting bolt 63 of the Z-clip 61 and the elongated hole 62. The part can be displaced without excessive force being applied. Further, even when the mounting bolt 63 is not provided at the center of the elongated hole 62 of the Z clip 61, the displacement can be absorbed at the interface between the Z clip 61 and the base material 50.

  In the above embodiment, two locking members 15 and 25 are provided in the longitudinal direction (length direction) of the base material 50 (51). One or three or more may be used, and the present invention is not limited to the above embodiment.

  Further, in the above-described embodiment, the configuration including the spacer member 17 has been described. However, the spacer member 17 is not necessarily required, and may be provided according to the wall structure 30, and is not limited to the above-described embodiment. .

  Furthermore, the above-described embodiment shows an example, and each configuration may be changed in various configurations within a range that does not impair the gist of the present invention, and the present invention is not limited to the above-described embodiment. .
