The present invention relates to a fixture and a wall structure for buildings.
Examples of fixtures of the related art are disclosed in PTL 1 to PTL 3. The fixture (fastener) disclosed in PTL 1 is used together with a joint filler that is disposed between left and right exterior wall plates (exterior materials) that are adjacent to each other. As shown in, for example,
By disposing the joint filler between the left and right exterior wall plates, transverse displacement of the left and right exterior wall plates is prevented.
The fixture (first securing metal fitting) that is disclosed in PTL 2 can be provided with a contact fitting (transverse displacement prevention metal fitting). The fixture extends in a horizontal direction, and includes an upper horizontal portion that is fixed to a metal backing member having the shape of a square wave. The contact fitting is such that the mounting portion includes an upper fixing plate and a lower fixing plate. By the fixture, the upper fixing plate is fixable to the metal backing and the lower fixing plate is fixable to the fixture, and at least one of the upper fixing plate and the lower fixing plate is fixed so as to extend through the metal backing. By disposing the contact fitting between facing side end portions of the left and right exterior wall plates, transverse displacement of the left and right exterior wall plates is prevented.
The fixture (securing jig main body) that is disclosed in PTL 3 can be provided with a contact fitting (left-right spacing plate). The fixture extends in a horizontal direction and is such that the substrate portion (rear plate) is fixed over a range of a plurality of backing members. Here, the fixing plate portion (fixing surface plate) to which the contact fitting of the fixture is fixed is formed on a side of the backing member so as to form a step with the substrate portion, and is disposed where the backing member does not exist. By disposing the erect piece (spacing piece) of the contact fitting (left-right spacing plate), fixed to the fixing plate portion, between facing side end portions of the left and right exterior wall plates (exterior wall materials), transverse displacement of the left and right exterior wall plates is prevented.

However, in the fixture described in PTL 1, since it is necessary to dispose the joint filler at a location that overlaps the vertical support bodies, the degree of layout freedom of the joint filler, which functions as a contact fitting, is low, and the degree of construction freedom of the exterior wall plates is not good. Here, the so-called “degree of layout freedom” refers to the degree of freedom in selecting the mounting position of the contact fitting with respect to a horizontal direction of the fixture, that is, a horizontal direction of the exterior wall plates. In addition, since construction for fixing the joint filler is always carried out on the vertical support materials, when the joint filler is fixed to the vertical support materials with a fastener, such as a screw, the strength and the durability of the vertical support materials may be reduced.
In the contact fitting described in PTL 2, since the contact fitting can be fixed to at least one of the metal backing member and the fixture, the degree of layout freedom of the contact fitting is higher than that in the fixture described in PTL 1. However, the procedure and content of the work differ when the lower fixing plate of the contact fitting is fixed to the upper horizontal portion of the fixture from when the upper fixing plate is fixed to the metal backing member, so that construction work tends to be complicated. Therefore, constructability is poor. In addition, since the fastener for fixing the contact fitting is fixed so as to extend through the metal backing, the strength and the durability of the backing may be reduced.
In the fixture described in PTL 3, since the contact fitting (left-right spacing plate) cannot be disposed at a location that overlaps the backing member, the degree of layout freedom of the contact fitting is low, and constructability of the exterior wall plates is not good. In addition, since the fixing plate portion (fixing surface plate) is formed on the side of the backing member so as to form a step with the substrate portion (rear plate), when a tapping screw screwed into the fixing plate portion for fixing the contact fitting is too long, the distal end of the tapping screw may damage a waterproof sheet or a column. Therefore, the waterproof property of the waterproof sheet and the strength and the durability of the column may be reduced.
The present invention has been made in view of the circumstances above of the related art, and an object of the present invention is to provide a fixture that can increase the degree of layout freedom of a contact fitting and facilitate construction and that can suppress a reduction in the strength and the durability of a building structure, and to provide a wall structure for buildings.
A fixture of a first embodiment of the present invention is capable of be provided with a contact fitting and is provided for mounting a wall material on a bolding structure, the fixture including:
a substrate portion hat is fixable to the building structure;
a first side wall portion that protrudes with respect to the substrate portion from one of side edges of the substrate portion;
a second side wall portion that protrudes from another of the side edges of the substrate portion towards a side that is same as a side towards which the first side wall portion protrudes;
a support portion that extends from a distal edge of the first side wall portion so as to face the substrate portion, and that approaches the second side wall portion;
a first locking portion that protrudes from the support portion towards a side opposite to the substrate portion, and that is bent towards a side of the first side wall portion;
a second locking portion that protrudes from the support portion towards the side opposite to the substrate portion, and that is bent towards a side of the second side wall portion; and
a fixing plate portion that extends from a distal edge of the second side wall portion so as to face the substrate portion, and that is disposed at a location closer than the support portion to the substrate portion,
wherein the contact fitting includes
In the fixture of the first embodiment, the fixing plate portion can extend along the substrate portion without being restricted by, for example, the uneven shape of the building structure and the location of, for example, a furring strip that constitutes the building structure. Therefore, it is possible to fix the mounting portion of the contact fitting at any location on the fixing plate portion.
Regardless of where the mounting portion of the contact fitting is fixed to the fixing plate portion, the procedure and content of the work are the same, so that the construction work is simplified.
Further, a fastening member, such as a screw, for fixing the contact fitting to the fixing plate portion is disposed apart from the substrate portion by a certain amount due to the length of the second side wall portion. Therefore, since the distal end of the fastening member is unlikely to damage a waterproof sheet and a column, it is possible to suppress a reduction in the waterproof property of the waterproof sheet and a reduction in the strength and the durability of the column.
Therefore, in the fixture of the first embodiment of the present invention, it is possible to increase the degree of layout freedom of the contact fitting and to facilitate construction, and to suppress a reduction in the strength and the durability of the building structure.
As a second embodiment of the present invention, it is desirable that the contact fitting include a restricting portion that protrudes from the mounting portion in a direction opposite to the erect piece, and that is contactable with a distal edge of the fixing plate portion.
In this case, by bringing the restricting portion of the contact fitting into contact with the distal end portion of the fixing plate portion of the fixture, the restricting portion helps to position the contact fitting. Therefore, construction work of an exterior wall plate is facilitated.
As a third embodiment of the present invention, it is desirable that the contact fitting include a facing piece that extends from the restricting portion so as to face the mounting portion, and that forms a gap between the facing piece and the mounting portion, a size of the gap being substantially equal to a plate thickness of the fixing plate portion.
In this case, by bringing the mounting portion of the contact fitting into contact with the fixing plate portion, bringing the restricting portion into contact with the distal edge of the fixing plate portion, and interposing the fixing plate portion between the mounting portion and the facing piece, the contact fitting can be easily positioned at the fixing plate portion of the fixture and temporarily fixed. Therefore, it is possible to easily and safely fix the contact fitting to the fixing plate portion by the fastening member.
As a fourth embodiment of the present invention, it is desirable that the contact fitting include a protruding piece that protrudes from the restricting portion in a direction opposite to the facing piece.
In this case, by holding the protruding piece of the contact fitting, a worker can easily bring the mounting portion of the contact fitting into contact with the fixing plate portion of the fixture, can easily bring the restricting portion into contact with the distal edge of the fixing plate portion, and can easily interpose the fixing plate portion between the mounting portion and the facing piece.
As a fifth embodiment of the present invention, it is desirable that the fixture have a through hole that is formed in, of the first side wall portion and the second side wall portion, at least the first side wall portion.
In this case, since, in the vicinity of the fixture, ventilation can be maintained and rainwater or the like can flow downward due to a space between a rear surface of an exterior wall plate and the fixing plate portion and due to the through hole, it is possible to suppress a reduction in the strength and the durability of the exterior wall plate and the building structure.
As a sixth embodiment of the present invention, it is desirable that the second side wall portion be inclined so as to approach the first side wall portion with decreasing distance to a side of the fixing plate portion from a side of the substrate portion.
In this case, since, for example, rainwater that has reached the second side wall portion from the building structure is allowed to flow in a direction away from the building structure due to the inclination, it is possible to suppress deterioration of the building structure.
As a seventh embodiment of the present invention, it is desirable that a slit that is recessed from a distal edge towards the support portion be formed in at least one of the first locking portion and the second locking portion.
In this case, even if at least one of the first locking portion and the second locking portion is locally deformed, it is possible to suppress the deformation from influencing the entire fixture by the slit.
As a result, it is possible to suppress torsional deformation of the fixture. In addition, when slits are formed at a certain interval, it is possible to easily measure the length of the fixture on the basis of, for example, the number of slits and the positional relationship between each slit and an end portion of the fixture.
A wall building structure for buildings according to an eighth embodiment of the present invention is a wall structure in which a wall material is mounted on a building structure by using a fixture that is capable of being provided with a contact fitting, wherein
the fixture includes
a substrate portion that is fixable to the building structure;
a first side wall portion that protrudes with respect to the substrate portion from one of side edges of the substrate portion,
a second side wall portion that protrudes from another of the side edges of the substrate portion towards a side that is same as a side towards which the first side wall portion protrudes,
a support portion that extends from a distal edge of the first side wall portion so as to face the substrate portion, that approaches the second side wall portion, and that is capable of supporting a rear surface of the wall material,
a first locking portion that protrudes from the support portion towards a side opposite to the substrate portion, that is bent towards a side of the first side wall portion, and that is capable of locking one end portion of the wall material,
a second locking portion that protrudes from the support portion towards the side opposite to the substrate portion, that is bent towards a side of the second side wall portion, and that is capable of locking another end portion of the wall material, and
a fixing plate portion that extends from a distal edge of the second side wall portion so as to face the substrate portion, and that is disposed at a location closer than the support portion to the substrate portion,
wherein the contact fitting includes
According to the wall structure for buildings of the eighth embodiment of the present invention, due to the operational effects provided by the fixture of the first embodiment, it is possible to increase the degree of layout freedom of the contact fitting and to facilitate construction, and to suppress a reduction in the strength and the durability of the building structure.
A fixture according to a ninth embodiment of the present invention is a fixture for mounting a wall material on a building structure, the fixture including:
a substrate portion;
a first side wall portion that protrudes with respect to the substrate portion from one of side edges of the substrate portion;
a second side wall portion that protrudes from another of the side edges of the substrate portion towards a side that is same as a side towards which the first side wall portion protrudes;
a support portion that extends from a distal edge of the first side wall portion so as to face the substrate portion, and that approaches the second side wall portion;
a first locking portion that protrudes from the support portion towards a side opposite to the substrate portion, and that is bent towards a side of the first side wall portion;
a second locking portion that protrudes from the support portion towards the side opposite to the substrate portion, and that is bent towards a side of the second side wall portion; and
a fixing plate portion that extends from a distal edge of the second side wall portion so as to face the substrate portion, and that is disposed at a location closer than the support portion to the substrate portion.
In the fixture of the ninth embodiment, the fixing plate portion having the above-described structure can extend along the substrate portion without being restricted by, for example, the uneven shape of the building structure and the location of, for example, a furring strip that constitutes the building structure. Therefore, an additional member, such as a member for preventing transverse displacement of the wall material, can be easily fixed to any location on the fixing plate portion.
Further, a fastening member, such as a screw, for fixing such an additional member to the fixing plate portion is disposed on a side opposite to the building structure with respect to the substrate portion. Therefore, since the distal end of the fastening member is unlikely to damage the waterproof sheet and the column, it is possible to suppress a reduction in the waterproof property of the waterproof sheet and a reduction in the strength and the durability of the column.
Therefore, in the fixture of the ninth embodiment of the present invention, it is possible to facilitate construction and to suppress a reduction in the strength and the durability of the building structure.
In the fixture and the wall structure for buildings of the present invention, it is possible to increase the degree of layout freedom of the contact fitting and to facilitate construction, and to suppress a reduction in the strength and the durability of the building structure.

Further, a plurality of exterior wall plates 2 are mounted on the fixtures 10 from thereabove so as to be adjacent to each other in the left-right direction. Even in this case, as shown in
Here, the fixtures 10 are used when mounting the plurality of exterior wall plates 2 so as to be adjacent to each other in the left-right direction. As shown in
Accordingly, the fixture 10 supports corner portions of a plurality of exterior wall plates 2 that are abutted against each other, that is, a four-side shiplap portion. By bringing the support portion 14 of the fixture 10 into contact with the rear surfaces 2B of the exterior wall plates 2, a ventilation space is ensured between the a wall surface of the building structure 8 and the rear surfaces 2B of the exterior wall plates 2.
By performing such work on the other exterior wall plates 2, the exterior wall plates 2 that are adjacent to each other in the up-down direction and the left-right direction are supported by the building structure 8, and cover the wall surface of the building structure 8.
<Operational Effects>
In each fixture 10 and the wall structure of the first embodiment, as shown in
Regardless of where the mounting portion 31 of the contact fitting 30 is fixed to the fixing plate portion 17 of the corresponding fixture 10, the procedure and content of the work are the same. Therefore, the restricting portion 33 of the contact fitting 30 allows the contact fitting 30 to be no longer inclined with respect to the fixture 10, and the contact fitting 30 to be precisely positioned with respect to the corresponding fixture 10 in the up-down direction. Therefore, the construction work is simplified.
Further, as shown in
Therefore, in each fixture 10 and the wall structure of the first embodiment, it is possible to increase the degree of layout freedom of the contact fitting 30 and to facilitate construction, and to make it possible to suppress a reduction in the strength and the durability of the building structure 8.
As shown in
Further, as shown in
As shown in, for example,
Further, the second side wall portion 13 is inclined downward so as to approach the first side wall portion 12 with decreasing distance to a side of the fixing plate portion 17 from a side of the substrate portion 11. Therefore, since, for example, rainwater that has reached the second side wall portion 13 from the building structure 8 is allowed to flow in a direction away from the building structure 8, it is possible to suppress deterioration of the building structure 8.
As shown in, for example,
As shown in
In each fixture 210, the fixing plate portion 17 of each fixture 10 of the first embodiment is changed to a fixing plate portion 217. The fixing plate portion 217 is bent from a distal edge 13A of a second side wall portion 13 and extends upward and away from a first side wall portion 12. The plate thickness of the fixing plate portion 217 is the same as the plate thickness T1 of the fixing plate portion 17 according to the first embodiment. A separation length of the fixing plate portion 217 from a substrate portion 11 in the exterior direction is the same as the separation length L1 of the fixing plate portion 17 according to the first embodiment from the substrate portion 11 in the exterior direction. The length of a threaded portion of a screw 30B protruding from the fixing plate portion 217 in the interior direction is the same as the length L3 of the threaded portion of the screw 30B according to the first embodiment protruding from the fixing plate portion 17 in the interior direction.
In each contact fitting 230, the restricting portion 33, the facing piece 34, and the protruding piece 35 of the contact fitting 30 of the first embodiment are changed to a restricting portion 233, a facing piece 234, and a protruding piece 235. The restricting portion 33, the facing piece 34, and the protruding piece 35 according to the first embodiment are positioned below the mounting portion 31 and the erect piece 32 that is connected to the left edge of the mounting portion 31. In contrast, the restricting portion 233, the facing piece 234, and the protruding piece 235 differ from the restricting portion 33, the facing 34, and the protruding piece 35 only in that they ace positioned above a mounting portion 31 and an erect piece 32 that is connected to a left edge of the mounting portion 31.
The restricting portion 233 is bent at substantially right angles from an upper edge of the mounting portion 31 and protrudes in the interior direction.
The facing piece 234 extends downward from the restricting portion 233 so as to face the mounting portion 31. The protruding piece 235 is bent at substantially right angles from an interior-side edge of the restricting portion 233, and extends upward in a direction opposite to the facing piece 234. A gap between the facing piece 334 and the mounting portion 31 is the same as the gap W1 between the facing piece 34 and the mounting portion 31 according to the first embodiment. That is, by inserting an upper edge 217A of the fixing plate portion 217 into the gap Wi between the mounting portion 31 and the facing piece 234, it is possible to interpose the fixing plate portion 217 between the mounting portion 31 and the facing piece 234.
Even in each fixture 210 and the wall structure of the second embodiment having such a configuration, similarly to the fixtures 10 and the wall structure of the first embodiment, it is possible to increase the degree of layout freedom of the contact fitting 230 and to facilitate construction, and to suppress a reduction in the strength and the durability of the building structure 8.
Although, in the foregoing description, forms of the present invention are described in accordance with the first and second embodiments, the forms of the present invention are not limited to the first and second embodiments above. Needless to say, the forms can be changed as appropriate within a scope that does not depart from the spirit thereof, and applied.
For example, although, in the first and second embodiments, the slits 16S are formed only in each second locking portion 16, other structures are possible. For example, slits similar to the slits 16S may be formed in each first locking portions 15.
When the second side wall portion 13 is inclined downward so as to approach the first side wall portion 12 with decreasing distance to the side of the fixing plate portion 17 from the side of the substrate portion 11, a structure in which through holes 13H are not formed in the second side wall portion 13 is also included in the present invention. In case, for example, rainwater that has reached the second side wall portion 13 can be collected at a location away from the building structure 8.
