Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of exterior panels used as exterior and interior materials for buildings, and more particularly, to a mounting bracket used when attaching the exterior panels to a wall base. The present invention relates to a wall structure formed thereby.

[0002]

2. Description of the Related Art Conventionally, as an exterior panel constituting a wall surface of a building, an exterior panel using a ceramic plate material has been generally widely used. In recent years, an exterior panel in which a heat insulating plate made of a foam material having extremely high heat insulating properties such as isocyanurate foam or rigid urethane foam is bonded to the back side of a ceramic plate is also used. Since the exterior panel to which the heat insulating plate is attached has excellent heat insulating properties, it is expected to be used more and more as an exterior material for an energy-saving house.

[0003]

In the case where the above-mentioned exterior panel is mounted on the base of the wall, nailing or screwing has hitherto been the mainstream. However, in the case of nailing construction, the nail head is conspicuous after construction and becomes unsightly. Therefore, when the color of the colored nails falls after nailing, the repair liquid is applied, but it does not match the color of the exterior panel, or it is painted more than the area of the nail head and it becomes noticeable after 2-3 years There are some difficult problems. Therefore, even if the color of the nail head has come off, sometimes the painted area is left as it is better than discoloring later. In the case of screw fixing, the color is applied directly to the screw head, or after the screw head is buried with putty and dried, the color is applied. Both materials are discolored later because of the various materials, and appear to rise up to about 10 yen coins, and the repair liquid applied to the screw head like a nail discolors later, etc. May cause problems after construction.

[0004] In order to avoid these problems, the use of a dedicated mounting bracket for mounting the exterior panel on the wall base has recently become mainstream. However,
In any of the above types of exterior panels, the thickness of the ceramic-based plate material may not be uniform.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a first type of mounting bracket according to the present invention, wherein (a) is a front view,
(B) is a side view.

The mounting bracket A is made of a single metal plate having a thickness of about 1 mm, such as a stainless steel plate, and is bent forward in the middle while leaving the legs 1a on both lower sides of the base 1. This forms a shorter arm 1b. And
The arm portion 1b has a downward bent portion 1c at its tip, and has receiving portions 2 extending forward from both sides of the lower end of the downward bent portion 1c. An upward bending portion 3 and a downward bending portion 4 which are bent vertically or substantially vertically are formed. Further, a downward locking portion 5 extending below the receiving portion 2 is provided at a position where the receiving portion 2 is not provided in the downward bent portion 1c. In the figures, reference numerals 6 and 7 denote nail holes.

FIG. 2 is a sectional view of a wall structure constructed by using the above-mentioned mounting bracket A. An airtight sheet (not shown) is attached to the wall outside shown in FIG. 1 as needed on the outdoor side of a wall base constituted by pillar members 10 such as pillars and studs, and a plurality of sheets are mounted on the outside with an attachment fitting A from above. It was constructed by attaching the exterior panel 20.

The exterior panel 20 used in this example is made of a well-known ceramic plate such as a calcium silicate plate, a cement pearlite plate, and a fiber-containing cement plate.
The upper and lower sides are cut to the conventional one. That is, a protrusion 20a is formed on the upper side of the exterior panel 20 by cutting out the front side, and a groove 20b corresponding to the thickness of the mounting bracket is formed on the lower side.

In order to improve the airtightness, a waterproof seal made of a foam-based hot melt or a rubber-based soft material is provided in the longitudinal direction at an appropriate position at the end. Also, the left and right edges of the exterior panel 20 may be cut so as to have a joint shape.

The construction of the wall using the exterior panel 20 and the mounting bracket A is performed in the following procedure. First, the mounting member A for supporting the lowermost exterior panel 20 is attached to the column member 10.
Is fixed with a fastener N such as a nail. In this case, one mounting bracket A is assigned to the joint of the two exterior panels 20. Next, the lowermost exterior panel 20 is placed so that the groove 20b on the lower side fits into the upwardly bent portion 3 of the mounting bracket A. Next, the lowermost exterior panel 20
The protrusion 20a on the upper side of the lower part of the mounting bracket A is
The fitting A is fixed to the column member 10 with a fastener N such as a nail.

Subsequently, the second-stage exterior panel 20 is placed so that the groove 20b on the lower side is fitted into the upwardly bent portion 3 of the mounting bracket A located on the lowermost exterior panel 20. At this time, if a waterproof seal is provided on the upper edge of the exterior panel 20, even if a slight gap is generated between the edges of the exterior panel 20 due to the attachment metal A, airtightness is maintained. After that, the third and subsequent exterior panels 20 are similarly fixed to the wall surface base.

On the wall surface thus formed, the upper side ridge 20a of the lower exterior panel 20 is fitted between the downwardly bent portion 4 and the downwardly engaging portion 5 of the mounting bracket A, and The upwardly bent portion 3 of the mounting bracket A is fixed in a state in which the upwardly bent portion 3 of the mounting bracket A is fitted into the lower side groove 20 b of the exterior panel 20. Therefore, even if the thickness of the upper panel and the lower panel is different, the position is determined based on the front side and the upper ridge 20a and the lower groove 20b are cut and processed, so that the surface on the wall surface after the construction is formed. No step is generated. Further, in the case where the phase-separated portion is cut, it is desirable that the fitting be properly fitted without making play such that a step is formed on the surface when fitted with the mounting bracket A.

As shown in FIG. 3, it is preferable that the contact portion a between the upper and lower exterior panels 20 be inclined forward so that the rainwater hitting the wall surface can easily flow.

FIG. 4 is a side view showing another example of the mounting bracket of the first type. This mounting bracket A 'is more downwardly directed to the tip of the shorter arm 1b than that shown in FIG. It has no bent portion, and the receiving portion 2 projects straight.
Specifically, the point having the pedestal portion 1 and the arm portion 1b is the same as the first type, but the downward locking portion 5 is formed by bending at a part of the tip of the arm portion 1b. In addition to the above, there is a receiving portion 2 extending forward where there is no downward locking portion 5, and at the tip of the receiving portion 2, an upward bending portion 3 and a downward bending portion 4 which are bent vertically or substantially vertically, respectively. Is formed.

The mounting bracket A 'shown in FIG. 4 is used for forming a wall surface with an exterior panel made of a ceramic plate. And the procedure of construction is the same as that described in FIG. 2, and the formed wall surface is also the same as that described in FIG. Therefore, even if the thickness of the exterior panel material in the upper and lower exterior panels is different, by determining the position based on the front side and cutting the ridge on the upper side and the groove on the lower side, the surface on the wall surface after construction No step is generated.

FIGS. 5A and 5B show an example of a second type of mounting bracket according to the present invention, wherein FIG. 5A is a front view and FIG. 5B is a side view.

The mounting bracket B is made of a single metal plate having a thickness of about 1 mm, such as a stainless steel plate. The mounting bracket B is bent forward in the middle while leaving the legs 1a on both lower sides of the pedestal 1. This forms a longer arm 1b. And
The arm portion 1b has a downward bent portion 1c at its tip, and has receiving portions 2 extending forward on both sides of the lower end of the downward bent portion 1c, respectively. An upward bending portion 3 and a downward bending portion 4 which are bent vertically or substantially vertically are formed. Further, a downward locking portion 5 extending below the receiving portion 2 is provided at a position where the receiving portion 2 is not provided in the downward bent portion 1c. In the figures, reference numerals 6 and 7 denote nail holes.

FIG. 6 is a cross-sectional view of a wall structure constructed using the mounting bracket B described above. An airtight sheet (not shown) is attached to the wall surface shown in FIG. 1 as necessary on the outdoor side of the wall surface composed of pillar members 10 such as pillars and studs. It was constructed by attaching the exterior panel 30.

The exterior panel 30 used in this example is formed by bonding a heat insulating plate 32 made of a foam material to the back side of an exterior plate 31 with an adhesive or the like.
The upper side and lower side are cut. That is, a protrusion 31a is formed on the upper side of the exterior plate member 31 by cutting out the front side, and a groove 31b corresponding to the thickness of the mounting bracket is formed on the lower side.

In order to improve the airtightness, a waterproof seal made of a foam-based hot melt or a rubber-based soft material is provided in the longitudinal direction at an appropriate position at the end. Further, it is sufficient that the left and right edges of the exterior plate material 31 and the heat insulation plate material 32 are cut so as to have a joint shape. Alternatively, a step may be formed by displacing and attaching the exterior plate 31 and the heat insulating plate 32.

As the foaming material constituting the heat insulating plate 32 of the exterior panel 30, the same materials as those conventionally used, such as isocyanurate foam, hard urethane foam, foamed polystyrene and foamed polyethylene, are used. Thickness of about 10 to 100 mm is used.
On the other hand, a ceramic type is used as the exterior plate material 31. Specifically, a square decorative plate made of a calcium silicate plate, a cement perlite plate, a fiber-mixed cement plate, or the like, having a size of about 1 to 25 mm is used.

The construction of the wall using the exterior panel 30 and the mounting bracket B is performed in the following procedure. First, the mounting member B for supporting the lowermost exterior panel 30 is attached to the column member 10.
Is fixed with a fastener N such as a nail. In this case, one mounting bracket B is assigned to the joint of the two exterior panels 30. Next, the mounting panel B is placed so that the groove 31b on the lower side of the outer panel material 31 of the lowermost outer panel 30 is fitted into the upwardly bent portion 3 of the mounting bracket B. Next, the projection 31a on the upper side of the exterior plate material 31 of the lowermost exterior panel 30 is fitted between the downwardly bent portion 4 and the downward locking portion 5 of the mounting bracket B, and the mounting bracket B Is fixed to the pillar member with a fastener N such as a nail.

Subsequently, the groove 31b on the lower side of the exterior plate 31 of the second exterior panel 30 is fitted into the upwardly bent portion 3 of the mounting bracket B located above the exterior plate of the lowermost exterior panel 30. And place it. At this time,
If the upper side edge of the exterior panel 30 has a waterproof seal, airtightness can be maintained even if a slight gap is formed between the edges of the exterior panel 30 due to the interposition of the mounting bracket B. Thereafter, the third and subsequent exterior panels 30 are similarly fixed to the wall base.

In the wall surface thus formed, the ridge 31a on the upper side of the exterior plate 31 of the lower exterior panel 30 fits between the downwardly bent portion 4 and the downwardly engaging portion 5 of the mounting bracket B. Then, the upper bent portion 3 of the mounting bracket B is fixed in a groove 31b on the lower side of the outer plate material 31 of the upper outer panel 30 in a fitted state. Therefore, even if the thickness of the exterior plate material 31 in the upper and lower exterior panels 30 is different, the position is determined with reference to the front side and the upper ridge 31a and the lower groove 31b are cut and processed, so that There is no step on the surface of the wall. Further, in the case where the phase-separated portion is cut, it is desirable that the fitting be properly fitted without making play such that a step is formed on the surface when fitted with the mounting bracket A. Further, since the heat insulating plate 32 of the exterior panel 30 is not related to the step on the panel surface, the thickness of the heat insulating plate 32 may vary.

In the example shown in FIG. 6, the thickness of the outer panel material 31 in the upper and lower outer panels 30 is normal and the same, but FIG. 7 shows the case where the thickness of the outer panel material 31 in the lower outer panel 30 is the upper layer. It shows the case where it is thicker than the one,
FIG. 8 shows a case where the thickness of the exterior plate material 31 in the upper exterior panel 30 is thicker than that in the lower exterior panel.

Also in the construction example using the second type of mounting bracket, in order to make it easy for rainwater to hit the wall surface to flow, the upper and lower exterior panels 30 are directed forward to the contact portions between the exterior plate members 31. It is the same as described above that it is preferable to provide a downward slope.

FIG. 9 is a side view showing another example of the mounting bracket of the second type. The mounting bracket B 'has a downwardly extending tip portion of the longer arm portion 1b as compared with that shown in FIG. It has no bent portion, and the receiving portion 2 projects straight.
Specifically, the point having the pedestal portion 1 and the arm portion 1b is the same as the first type, but the downward locking portion 5 is formed by bending at a part of the tip of the arm portion 1b. In addition to the above, there is a receiving portion 2 extending forward where there is no downward locking portion 5, and at the tip of the receiving portion 2, an upward bending portion 3 and a downward bending portion 4 which are bent vertically or substantially vertically, respectively. Is formed.

The mounting bracket B 'shown in FIG. 9 is used when a wall surface is formed by a heat-insulating exterior panel in which a heat-insulating plate is bonded to the back side of the exterior plate. The procedure of the construction is the same as that described with reference to FIG. 6, and the formed wall surface is the same as that described with reference to FIG. Therefore, even if the thickness of the exterior panel material in the upper and lower exterior panels is different, by determining the position based on the front side and cutting the ridge on the upper side and the groove on the lower side, the surface on the wall surface after construction No step is generated.

As described above, the present invention has been described in detail based on the embodiments. However, the mounting bracket according to the present invention is not limited to the above-described embodiments at all, and does not depart from the gist of the present invention. It goes without saying that various changes are possible.

For example, the pedestal may be raised by providing a step on the top and bottom of the pedestal by bending. In the straight type where the pedestal part is flat, when the mounting bracket is fixed to the wall surface base with nails or screws, the nail head or screw head will inevitably protrude, so such a floating type can substantially eliminate the protrusion . In addition, the strength of the mounting bracket can be improved by bending.

When mounting the wall surface, either a straight type or a floating type mounting bracket may be employed, but the straight type is preferable in order to maintain airtightness without forming a gap between the wall surface base and the mounting bracket. In the case of the straight type, nail heads and screw heads protrude, but in the case of the exterior panel where the insulation panel is attached to the back of the exterior panel, the back side is soft with foam material, and the nail or screw head easily sinks into it Therefore, there is no step on the front side. As for the strength, the material may be made slightly thicker or the strength of the material itself may be increased.

In the case where the mounting bracket is made of metal, if the exterior plate is cooled by cold outside air in winter, the mounting bracket may be cooled and dew may be formed on the surface. In order to prevent this dew condensation, it is preferable to coat the surface of any of the above-mentioned types of fittings with a resin.

[0038]

As described above, according to the mounting bracket of the present invention, the position of the exterior panel itself or the exterior panel material of the exterior panel to be attached to the wall surface is determined based on the front side, and the projection is formed on the upper side. When the wall is formed, the ridge on the upper side fits between the downward bending portion and the downward locking portion of the mounting bracket, and the groove on the lower side faces upward in the groove on the lower side. Since the bent portion is fixed in the fitted state, the wall surface can be constructed without generating a step on the surface.

Further, the wall surface structure of the present invention is intended for an exterior panel formed by determining a position with reference to the front side of the exterior panel itself or the exterior panel material of the exterior panel, and cutting a ridge on an upper side thereof and a groove on a lower side thereof. A wall surface is formed by the exterior panel using the above-mentioned mounting bracket, and a ridge on an upper side of the exterior panel or the exterior panel material of the exterior panel is fitted between a downward bent portion and a downward locking portion of the mounting bracket. In combination, the exterior panel is fixed to the wall surface with the upwardly bent portion of the mounting fitting fitted into the groove on the lower side, so that a beautiful finish with no level difference on the surface is obtained.
