Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall device formed by press molding a metal plate material such as a stainless steel plate. More specifically, the present invention provides an outer wall device that can be easily formed of a metal plate material having low workability such as a stainless steel plate and that has good drainage of rainwater.

[0002]

2. Description of the Related Art Conventionally, as a makeup wall for an outer wall of a building or the like, a tile of ceramics is generally attached with cement mortar. However, such an outer wall is not preferable in terms of safety since it is troublesome to construct and requires skill and the outer wall tiles may be peeled off.

In order to solve such a problem, recently, an outer wall is often made of a metal plate material.
In many cases, in order to facilitate the construction, for example, a frame member is attached to a wall foundation of a building frame, and a unitized metal surface plate is attached to these frame members.

However, in such a structure, rainwater penetrates into the joints of the surface plates, that is, the joints, and passes through the gaps between these joints or the gaps between the joint and the wall base on the back side of the joints. Flow down. Especially, in such an outer wall, in order to simplify the construction and the structure of the base frame member,
The joints are attached in a so-called potato joint arrangement, which is continuous in a grid pattern. In such a structure, vertical joints in the vertical direction are continuous in a straight line from the upper part to the lower part of the entire wall.
Therefore, most of the rainwater that has fallen on the surface plate of such an outer wall generally flows into the vertical joints that are continuous in the vertical direction and flows down the vertical joints. For this reason,
A lot of rainwater flows in the back of this vertical joint,
Impairs the waterproofness of the wall base. In addition, water that has entered the vertical joints from the surface members may accumulate along the wall base material while flowing down, and may flow out from the vertical joints to the surface of the surface member at the lower part of the wall. In such a case, there was a problem that dust on the surface of the wall base or a substance dissolved from concrete remained on the trace of rainwater flowing near the vertical joint, impairing the appearance.

In order to prevent such a problem, it is conceivable to apply a waterproof joint or waterproof caulking to the joint of the surface plate. However, if waterproof joints or waterproof caulks are applied to all joints of these surface plates, there is a problem that the construction is troublesome, the efficiency is lowered, and the cost is increased. Furthermore, such waterproof joints and waterproof caulks have a problem such as impairing the appearance of the outer wall.

Further, it is preferable to use a stainless steel plate as at least the surface plate of the outer wall device made of the metal plate material as described above. This stainless steel material has features such as high corrosion resistance, high surface hardness, low chemical activity on the surface, stain resistance, and easy cleaning.

However, this stainless steel material has a low workability, and when such a material is used for the outer wall device, the plate material of this stainless steel material is press-formed into a simple shape in view of the manufacturing cost and the like. It is necessary to reduce the number of parts to be machined and other processed as much as possible. In addition, as a matter of course, such an outer wall device must have a simple structure and easy construction, and can reduce the cost.

[0008]

SUMMARY OF THE INVENTION The present invention has been made based on the above circumstances. Drainage of rainwater is good, the waterproofness of the wall foundation is not impaired, and traces of rainwater may remain. And an outer wall device that is easy to process and can reduce costs even when using a material with low workability such as a stainless steel plate, has a simple structure, is easy to install, and has a good appearance Is.

Therefore, the rainwater does not flow down the wall base on the back side of the joint portion, and the waterproofness of the wall base is not impaired. Further, once the rainwater that has entered the joint portions flows into the trough-shaped mounting frame member, it will flow down to the lower portion of the mounting frame member as it is, and will not flow out from the joint portions of these surface members again. Absent. Therefore, no trace of rainwater flow is left on the joint portion of the surface member, and the appearance is not impaired.

Further, the surface member and the mounting frame member have a simple structure in which the edges of the metal plate material are simply bent. Even if a hard material such as a stainless steel plate is used as the metal plate material, its processing is performed. Is easy and cost is reduced, and construction is easy.

According to a second aspect of the present invention, the mounting frame member is provided with a fitting receiving portion formed by bending both side edge portions of a strip-shaped metal plate material so as to face each other, A groove portion having a deepened back is formed by the central substrate portion of the strip-shaped metal plate member and the fitting receiving portions on both sides.

Therefore, since the structure is simple and the surface member can be securely held, and since the groove portion which is widened in the back is formed, the rainwater that has once entered the groove portion through the joint portion of the surface member. Will flow down without leaking to the outside again, ensuring the waterproofness of the wall foundation and also reliably preventing the trace of rainwater flowing down at the joint portion.

According to a third aspect of the present invention, the mounting frame member is mounted on the wall base of the frame along the vertical direction, and the surface member slides on these mounting frame members. They are freely fitted and these surface members are pressed against each other by gravity.

Therefore, since these surface members are pressed and fixed to each other by gravity and play or rattling is prevented, it is not necessary to specially fix these surface plates. Therefore, the structure becomes simple, and at the time of construction, it is only necessary to sequentially fit the surface member from the upper end portion of the mounting frame member and slide it downward, and the construction becomes extremely easy.

According to a fourth aspect of the present invention, a second gutter surrounded by the fitting edge portion of the surface member and the attachment receiving portion of the attachment frame member is provided. The shaped part is formed. Therefore, the rainwater that has entered from the joint first flows down in the second gutter-shaped portion and is more reliably prevented from reaching the wall foundation.

According to a fifth aspect of the present invention, the fitting edge portion of the surface member and the fitting receiving portion of the mounting frame member are fitted to each other at right angles to the longitudinal direction of the mounting frame member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention, which is an outer wall device for makeup of an outer wall of a building. Reference numeral 1 in the figure is a wall foundation of this building structure. The wall base 1 is simply waterproofed in preparation for rainwater intrusion. For example, if the body is concrete,
No special waterproofing is required.

A plurality of mounting frame members 10 are attached to the wall base 1 along the vertical direction at predetermined intervals by concrete nails 15 or the like. A plurality of surface members 2 are fitted and held on these mounting frame members 10. In the case of this embodiment, both the surface member 2 and the mounting frame member 10 are formed by press-molding a stainless steel plate, and this embodiment uses a hard stainless steel plate having such low workability. In consideration of this, the structure is easy to process. In addition,
Each of the above surface members 2 has a rectangular shape with the same shape and size, and is attached in a so-called potato joint arrangement in which joints of these joints form a lattice.

The surface member 2 is formed by bending an edge portion of a stainless steel plate as shown in FIG. 4, and has a flat surface portion 3 serving as a decorative plate on the surface and each edge portion inside. And flanges 4a and 4b formed by bending the same at approximately 90 degrees. Then, as shown in FIG. 2, of these flange portions, for example, the tip edge portions of the pair of flanges 4b at the both side edge portions are further bent by approximately 90 ° in the opposite directions, and the fitting edge portions 6 are respectively formed. Are formed. In addition, the width of the flange portions 4b at the both side edge portions is formed to be wider than the width of the flange portion 4a at the upper and lower edge portions, and therefore, the tip edges of these flange portions 4a and the fitting edge portion 6 described above. A gap is formed between them.

In this embodiment, the surface member 2
The stainless steel plate of is a matte finish with a metallic luster,
The surface portion 3 is a flat surface, but depending on the specifications, the surface portion 3
Can be colored or an uneven pattern can be formed.

The mounting frame member 10 is formed by bending a strip-shaped member of stainless steel plate so that both side edges thereof face each other as shown in FIG. This bent portion is bent by 180 ° and is overlapped and closely adhered to both side edge portions of the substrate portion 11 in the central portion of the belt-shaped member, and the tip edge of these overlapped edge portions 12 is overlapped. And a fitting receiving portion 13 formed by further bending the portion.

The fitting receiving portion 13 is the substrate portion 11 described above.
And is bent in a chevron shape, and the tip of the fitting receiving portion 13 is inclined with respect to the base plate portion 11. The tip edges of these fitting receiving portions 13 are separated from each other by forming a predetermined gap. Therefore,
The board portion 11 and the fitting receiving portions 13 form a groove portion 14 having a cross-sectional shape with an enlarged depth. In addition,
The mounting frame member 10 is formed by roll-forming or the like of the band-shaped stainless steel plate as described above, and has a long gutter shape as a whole.

Then, mounting holes 15 are formed at a predetermined interval so as to penetrate through the above-mentioned overlapping edge portion 12 of the mounting frame member 10 and both side edge portions of the substrate portion 11, and concrete nails that penetrate these mounting holes 15 are formed. 16 and so on, this mounting frame member
0 is attached to the wall base 1.

These mounting frame members 10 are continuously mounted from the upper end to the lower end of the wall along the vertical direction at intervals substantially corresponding to the width of the surface member 2. Then, in the fitting receiving portion 13 of the mounting frame member 10, the surface member 2
The fitting edge portions 6 of are fitted and the surface members 2 are attached to the wall base 10 via the attachment frame members 10.

The surface member 2 is slidably fitted in the mounting frame member 10 in its longitudinal direction, that is, in the vertical direction. The flange portions 4a at the upper and lower edges of the vertically adjacent surface member 2 are in close contact with each other, and the flange portions 4b at both side edges of the vertically adjacent surface member 2 are also in close contact with each other. The surface members 2 are pressed against each other in the vertical direction by gravity, and are fixed so as to prevent play or rattling with respect to the mounting frame member 10. The uppermost surface member 2 is fixed to the mounting frame member 10 or the wall base 1 by an appropriate means such as a screw or a nail.

The fitting edge portion 6 of the surface member 2 and the fitting receiving portion 13 of the mounting frame member 10 are fitted to each other by dimensioning each portion so that a predetermined play is generated in the left and right direction. There is. The surface members 2 are attached so as to press each other from both the left and right sides of the wall, and the flange portions 4b on both side edge portions of the surface members 2 adjacent to each other on the left and right are also in close contact with each other.

The surface member 2 and the mounting frame member 10 described above are used.
Since the play as described above is formed in the left-right direction of the mounting frame member 10, that is, in the direction orthogonal to the longitudinal direction of the mounting frame member 10, after the surface members 2 are fitted into these mounting frame members 10, As described above, the flange portions 4b of the surface member 2 can be moved left and right so as to be in close contact with each other. Further, due to this play, it is possible to absorb the error in the interval when the mounting frame members 10 are mounted. Further, since such play is formed, a joint member can be interposed between the flange portions 4a and 4b of these surface members 2.

When the outer wall device as described above is constructed, the mounting frame members 10 are first mounted on the wall base 1 along the vertical direction at predetermined intervals. Next, a stopper member (not shown) made of an angle member or the like is attached to the lower ends of the mounting frame members 10 so that the surface member 2 at the lowermost end is supported on the stopper member. It should be noted that this stopper member can be constructed with an appropriate structure at the construction site according to the condition at the construction site or the structure of the wall foundation. When constructing the stopper member, drainage is carried out from inside the gutter-shaped mounting frame member 10 so as not to close the lower end portion of the mounting frame member 10.

Next, the surface member 2 is fitted from the upper ends of the mounting frame members 10 as described above, and the surface member 2 is slid downward along the mounting frame member 10 so that these surfaces are The members 2 are sequentially stacked. Along with this, these surface members 2 are moved in the horizontal direction, and the flange portions 4b at both side edge portions thereof are brought into close contact with each other. After all the surface members 2 are attached in close contact with each other in this manner, the uppermost surface member 2 is fixed with screws, nails or the like, if necessary.
In addition, the upper edge of the uppermost surface member 2 is waterproofed to prevent rain. If necessary, the surface members 2 on both the left and right sides of the wall are also fixed so that no gap is formed on both sides of these surface members 2.

In such an outer wall device, by simply fitting the surface member 2 from the upper end of the mounting frame member 10 and sliding the surface member 2 as described above, the surface members 2 are pressed against each other by gravity and fixed. , Fixed so that no play occurs.
Therefore, the construction is simple and efficient.

The rainwater that has poured down on the surface member 2 enters the gap between the flange portions 4a and 4b, that is, the joint portion. In this case, since the joint between the flange portions 4a at the upper and lower edges is in the horizontal direction, the amount of rainwater that invades this joint is small, and this invading rainwater does not flow into the wall base 1 on the back surface. Absent.

On the other hand, the flange portions 4 on both the left and right edges
Rainwater that has entered the joints in the vertical direction between b flows downward in the joints. In this case, since the vertical joint is continuous from the upper part to the lower part of the wall, the rainwater that has invaded into the vertical joint gradually accumulates and gradually increases as the amount of runoff goes to the lower part. Therefore, when the wind and rain are strong, the amount of rainwater flowing down along the vertical joints is large and overflows to the back surface. For this reason, a considerable amount of rainwater flows along the wall base 1, impairing the waterproofness of the wall base 1, and rainwater may enter the interior. Further, in the lower part of the wall, rainwater once invading to the back surface may flow down along the wall base material 1 and may overflow again to the surface of the surface member 2 through the vertical joints. In such a case, this wall foundation 1
If the surface dust of the surface or the wall base 1 is a concrete wall, its components will dissolve into the rainwater, and this will remain in the trace of the rainwater flowing near the vertical joints of the surface member 2,
The appearance may be impaired.

However, since the above-mentioned trough-shaped mounting frame member 10 is continuously provided on the back side of this vertical joint, rainwater that has invaded the back surface from this vertical joint is not attached to this mounting frame member. It flows down in 10 and is drained from its lower end.
Therefore, the rainwater that has entered from the vertical joint does not flow down the wall base 1, and the waterproofness of the wall base 1 is not impaired. Further, since the mounting frame member 10 has a gutter shape, the rainwater that has entered the inside thereof quickly reaches the lower end portion and is drained. Therefore, the rainwater does not flow out again to the surface of the surface member 2 through the vertical joints, and no trace of the rainwater flows near the vertical joints of the surface member 2.
In addition, in this embodiment, since the inside of the mounting frame member 10 is formed in the groove portion 14 having the above-described deep spreading,
Rainwater that once flows into the groove portion 14 is reliably prevented from flowing out of the groove portion 14 again.

Further, the fitting receiving portion 13 of the mounting frame member 10
Since the tip end of the surface member 2 is angled and inclined,
Even if the fitting edge portion 6 of the above-mentioned fitting contact the fitting receiving portion 13, the contact point is only one point of the tip edge of the fitting receiving portion 13, and the fitting edge portion 6 is fitted to the surface of the fitting edge portion 6. There is no close contact with the surface of the receiving portion 13, rainwater does not accumulate in the gap between them due to the capillary force, and drainage becomes good. In addition, since the fitting receiving portion 13 is bent in a mountain shape in cross section, it has high rigidity and high strength.

As described above, such an outer wall device has a simple structure and is low in cost, and the construction is simple and efficient. In addition, because the drainage of rainwater is good as described above,
There is no need to waterproof the joints, so the construction is easy and the appearance is good. In the above-described embodiment, the flange portions 4a and 4b of the surface member 2 are directly adhered to each other, but as described above, the joint widths are adjusted to make the unevenness inconspicuous, or a design effect is obtained. Therefore, a joint member that also serves as a spacer may be interposed between them. Even in this case, it is as described above that the joint member is not required to be waterproofed.

In the above embodiment, the mounting frame member 10 is mounted in the vertical direction. However, in the case of a wall having a low height and a wide width, the mounting frame member 10 is mounted in the horizontal direction. May be. In this case, joints between the flange portions 4a of the surface members 2 are vertical joints that are continuous in the vertical direction, and rainwater flows in the vertical joints. Rainwater flowing in these vertical joints flows into the mounting frame member 10 for each step, flows in the groove portions 14 and is drained. In this case, since the mounting frame members 10 are arranged in the horizontal direction, the efficiency of drainage in the groove portion 14 is low. However, since only the rainwater that has fallen on the surface member 2 for one step flows into each of the mounting frame members 10, sufficient drainage is possible in the groove portion 14 of each mounting frame member 10. In addition, in this case, it is necessary to perform drainage construction such as forming a gap for drainage at the seam of each mounting frame member 10, etc. However, these drainage constructions may be performed on-site as appropriate according to the state of the site. You can do it.

FIG. 5 shows a second embodiment of the present invention. In this case, the mounting frame member 30 is a gutter-shaped member having a fitting receiving portion 31 having a U-shaped cross section. The fitting edge portion of the surface member 2 is composed of a tapered fitting slope portion 33 and a tip fitting edge portion 34 in which the tip edge portions of the fitting slope portion 33 are bent so as to face each other. Has been done.

In this case, when the surface members 2 are pressed against each other, the above-mentioned fitting slope portion 33 causes the fitting receiving portion 3 of the mounting frame member.
The front surface member 2 is moved to the front side by abutting on the front end portion of the first member 1. In this state, the front end fitting edge portion 34 is fitted and held by the front end portion of the fitting receiving portion 31. And the above-mentioned fitting receiving portion 3
A second gutter-like portion 35 surrounded by the tip end portion 1, the fitting slope portion 33, and the tip end fitting portion 34 is formed.

Therefore, the rainwater that has entered the joint portion between the flange portions 4b flows down in the trough portion 35. Further, the rainwater leaking from the gutter-shaped portion 35 flows down in the gutter-shaped mounting frame member 30, so that the rainwater is reliably prevented from flowing down along the wall base. In addition,
The second embodiment has the same structure as that of the first embodiment except for the above points, and the portions corresponding to those of the first embodiment in FIG. Is omitted.

The present invention is not limited to the above embodiment. For example, the cross-sectional shape of the above-mentioned mounting frame member is not necessarily limited to the one described above, and if the fitting edge portion of the surface member can be fitted and has a gutter shape, another shape is adopted. can do. Further, the materials for the surface member and the mounting frame member are not necessarily limited to the stainless steel plate as described above, and an aluminum plate, a corrosion-resistant steel plate, or the like can be used.

[0043]

As described above, according to the present invention, the rainwater that has entered the vertical joint portion flows down through the trough-shaped mounting frame member and is drained. Therefore, this rainwater flows down along the wall base material. Therefore, the waterproof property is not impaired, and the rainwater once flowing into the mounting frame member does not immediately flow down and flow again from the joint portion to the surface to leave a trace of rainwater. Further, since this structure has a simple structure, it is possible to easily process a material having low workability such as a stainless steel plate, and the construction is simple and the cost can be reduced.
