Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention can be applied to a roof having a three-dimensional curved surface, which has been increasing in recent years, and a roof made of a polyhedron. In particular, the present invention is applicable to a case where an exterior material is directly laid on the upper surface of an H-section steel or the like. TECHNICAL FIELD The present invention relates to a building exterior structure that can be suitably used for a simple roof structure.

[0002]

2. Description of the Related Art In recent years, roofs having a dome shape, a conical shape, or the like, or roofs having a dome shape, a conical shape, or the like in part have increased due to diversification of external designs. For such a roof, a method is known in which the roof plate itself or a drainage plate is formed into a tapered shape and roofed. On the other hand, with the use of the effective volume in the building, the lightening of the roof structure, the reduction in the number of building materials used, etc., exterior materials are laid directly on the frame such as H-section steel to increase the surface strength. A roof structure that bears the exterior material has been proposed and partially implemented.

[0003]

However, the method for forming the roof slab into a tapered shape has the following problems. That is, various forming machines for forming a tapered roof shingle have been proposed, but most of them can form only one side edge of the left and right sides, and can only form side edges along the traveling direction of the forming material. Therefore, one side edge of the material cut in advance into a taper shape is formed, and after the material completely passes through the molding machine, the other side edge is brought into parallel with the traveling direction to another molding machine. You have to take the troublesome procedure of molding without making. In short, an operation of facing the other side edge so as to be parallel to the traveling direction and a space (length of the material in the traveling direction) for performing the operation are required. For this reason, even if two molding machines are arranged opposite to each other, twice as much labor and almost twice the molding space are required for roll molding that simultaneously processes both side edges as in the case of molding a roof plate with a constant width. There was a problem that it became necessary. Also, 2
When two molding machines are arranged in a row, it is necessary to install them at a distance apart in the direction of material movement, so that more than twice the molding space is required for the molding of a roof plate with a constant width. Becomes Furthermore, it is necessary to form the taper dimension according to the roof shape, and if there is a minute forming error, as in the case where there is a mounting error in the holding member or the like disposed on the roof surface, poor fitting etc. May have occurred. A similar problem occurs when the drainage plate is formed into a tapered shape. Further, as disclosed in Japanese Patent Application Laid-Open No. H10-266480, the present applicant has proposed a roof structure in which a roof plate having a constant width can be used by using a tapered cover material. Since the cover material has a smaller shape and a smaller volume of space than the exterior material, it can prevent or significantly reduce the increase in the molding space during taper processing. There is no improvement in the necessity of forming into a taper size according to the above. In particular, in a roof structure in which a shingle is laid directly on a skeleton, a more reliable rain-breaking property is required. Therefore, the present invention can be applied to a roof having a three-dimensional curved surface or a roof made of a polyhedron, and in particular, can be suitably used for a roof structure in which an exterior material is directly laid on an upper surface such as an H-shaped steel. The aim is to propose a structure.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above-mentioned circumstances, and is an exterior structure using a building exterior material having rising portions at both ends of a substantially central portion. The raised portion is extended substantially inwardly to form an overlapped portion, and the upper end of the other raised portion is extended outward to form a overlapped portion. The present invention relates to a building exterior structure characterized by being mounted so as to cover a portion to be overlapped, and being mounted by displacing the overlapping position of the overlapped portion and the portion to be overlapped in the width direction.

The present invention also relates to an exterior structure using an architectural exterior material having rising portions at both ends of a substantially central portion, wherein upper ends of both rising portions of the exterior material are substantially folded inward. It is characterized in that it is extended to form a portion to be polymerized, a cover material is attached so as to cover the portion to be polymerized of an adjacent exterior material, and the cover material and the portion to be polymerized are displaced in the width direction and attached. It also proposes a building exterior structure.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the architectural exterior structure of the present invention may be constituted by only an exterior material or by an exterior material and a cover material.

The exterior structure shown in FIG. 1 is a case where only the exterior material is used, and the upper end of one (right side) rising portion 12 of the exterior material 1 is extended substantially inward (left) in a folded manner. To form an overlapped portion 14, and the other (left side) rising portion 1
This is a configuration in which the overlapping portion 15 is formed by extending the upper end of 2 outward (left). Then, one of the rising portions 12 of the exterior material 1 is attached to the base 4 with the holding member 2 and the support member 3, and the overlapping portion 15 is attached so as to cover the overlapped portion 14 of the adjacent exterior material 1, thereby forming the exterior structure. Building.

As shown in FIG. 2A, the exterior material 1 used in FIG. 1 has a substantially horizontal rising portion 12 at both ends of a substantially central portion 11. The one (right) rising portion 12 is formed into a substantially V-shape by bending outward (right) side downward, then outward (right) side upward, and further inward (left) side downward. The first engaged portion 121, the inclined surface portion 122, and the second engaged portion 123 formed in a substantially inverted V shape are formed in this order from below. A drainage groove 13 extends on the inner (left) side of the second engaged portion 123, and on the inner (left) side, a substantially horizontal overlapped portion 14 whose tip is bent downward. Is extended. A substantially horizontal piece-shaped overlapping portion 15 extends outside the upper end (left side) of the other (left side) rising portion 12, and the tip is bent downward.

As shown in FIGS. 2 (b) and 2 (e), a holding member 2 for holding the exterior material 1 used in FIG. 1 has a substantially √-shaped lower piece 21 and a substantially L-shaped upper piece 22. Are connected to each other in a hinge shape, and a V-shaped lower jaw 2 is attached to a side end (lower end) of the lower piece 21.
An upper U-shaped upper jaw 221 is formed at a side end of the upper piece 22, and a through hole 25 such as a bolt 23 (nut 24) is formed in the center of each of the horizontal pieces of the lower piece 21 and the upper piece 22. Are formed, and can be joined in close contact. In the holding member 2, the upper piece 22 is rotatable with respect to the lower piece 21, that is, the upper jaw 221 is configured to be rotatable with respect to the lower jaw 211. Note that at least the lower jaw 211 is upward, and the upper jaw 2
21 is provided with downward locking pieces, and these are arranged and fixed to face each other, so that the first engaged portion 121, the slope portion 122, and the second
The engaged portion 123 can be locked so as to be gripped from above and below.

In FIG. 1, the holding member 2 is
It is arranged and fixed on a support member 3 such as a tight frame fixed on a base 4 such as a mold steel. As shown in FIG. 2 (c), the support member 3 includes inclined legs 32, 32 inclined downward and to the left and right of a substantially horizontal fixed receiving portion 31.
2 is provided with a fixing portion 33 along the base 4 at a lower end thereof, and the fixing receiving portion 31 and the inclined leg portion 32 of the support member 3 are provided.
The lower piece 21 of the holding member 2 is fixed so as to be in close contact with the holding member 2.
It should be noted that a nut 24 is fixed to the back surface of the fixing receiving portion 31 in the illustrated embodiment in advance by welding or the like, and is fixed integrally with the bolt 23. Further, the base member 4 for fixing the support member 3 is generally a steel frame such as a beam, a purlin or a rim, but is not limited thereto. For example, a configuration in which a base material such as a wood wool cement board, a wood chip cement board, a lightweight cellular concrete board, or the like is laid on the steel frame body,
There is also a configuration in which a steel frame or a wooden hut is laid on a concrete frame, or the support member 3 may be directly attached to a concrete surface whose foundation has been adjusted. Therefore, the foundation 4 to be constructed in the present invention refers to all building frames to which the support member 3 can be attached by means of fixing means such as nails, screws, anchors, welding, adhesives, etc. It includes all the bases with boards or the like required for performance.

The materials of the holding member 2 and the exterior material 1 are not particularly limited. For example, the holding member 2 is usually 0.6 mm depending on the size, strength, and the like of the exterior material 1.
It is formed by pressing a stainless steel plate, a plated steel plate, or the like having a thickness of about 3.2 mm, or the like, but an extruded aluminum material may be used. The exterior material 1 is typically made of a surface-decorated steel sheet, a stainless steel sheet, a laminated steel sheet, a hot-dip galvanized steel sheet, a galvanium steel sheet, or another rust-proofing steel sheet having a thickness of about 0.4 to 1.6 mm, a special steel, and a non-ferrous metal ,
A known metal material such as an aluminum alloy plate, a lead plate, a zinc plate, a titanium alloy plate, or a copper plate is formed into a predetermined shape by roll forming, press forming, or other means. In particular, a relatively thick plate thickness of about 0.8 to 1.6 mm is preferable in order to ensure the strength of the positive and negative pressures as the surface. Furthermore, on the back surface of the exterior material 1,
For reasons of dew condensation prevention, soundproofing, and fireproofing measures, a backing material such as polyethylene foam or glass wool sheet may be added as necessary.

In order to apply the exterior structure shown in FIG. 1 to a roof having a three-dimensional curved surface or a roof made of a polyhedron, first, the arrangement interval of the support members 3 on the base 4 (interval in the horizontal direction). Is narrow on the ridge side and wide on the eave side, that is, it is installed in a substantially tapered shape so that it gradually expands from the ridge to the eave. The arrangement interval of the support members 3 with respect to the roof surface is easily set by computer analysis. Then, the lower piece 21 of the holding member 2 is welded and fixed to the fixing receiving portion 31 of the support member 3 along the horizontal piece. Alternatively, the lower piece 21 of the holding member 2 may be fixed to the support member 3 in advance with an adhesive, a bolt, a nut, or the like. In this way, the lower jaw 211 is placed and fixed on the base 4 before disposing the exterior material 1.

Next, when the exterior material 1 is to be laid (laid), it is arranged so that the first engaged portion 121 is engaged with the lower jaw 211. At this point, since the upper piece 22 of the holding member 2 is rotatable, the outer piece 1 may be provided by rotating the upper piece 22 in a floating state.

Subsequently, the upper piece 22 is rotated so that the upper jaw 221 presses the second engaged portion 123 of the exterior material 1 from above, and the horizontal piece is closely attached to the horizontal piece of the lower piece 21. And fixed integrally with bolts 23 and nuts 24.

Thereafter, the overlapping portion 15 extending to the rising portion 12 on the other side (left side) of the exterior material 1 is connected to the overlapped portion 14 extending to the rising portion 12 on one side (right side) of the exterior material 1 adjacent to the left side. Screw to cover the screw (screw 1
6) Fix. At this time, the screw stop (screw 16) position is on the base end side of the overlapping portion 15 on the relatively ridge side as shown in FIG. 3A, but is relatively on the eave side as shown in FIG. 3C. The position of the screw stop (screw 16) is displaced to the tip side of the overlapping portion 15, and the overlapping portion 15 and the overlapped portion 14 in the eaves ridge direction.
Is mounted with its overlapping position displaced in the width direction. This screwing may be performed at a position where the holding member 2 and the supporting member 3 do not exist, and can be performed at appropriate intervals. In addition, when the overlapping position of the overlapping portion 15 and the overlapped portion 14 is displaced in the width direction, it is possible to finely adjust the substantially inclined rising portion 12 by intentionally inclining it.

FIG. 3 (b) is a cross-sectional view which is located at an intermediate position between the relatively ridge side position in FIG. 3 (a) and the relatively eave side position in FIG. 3 (c). Support member 3
Is provided with a lower jaw 61 and an upper jaw 62 similar to the lower jaw 211 and the upper jaw 221 of the holding member 2 in a part where the holding member 2 is not provided. The hanging part 63 is extended.

In the exterior structure of the present invention constructed in this manner, the overlapping position of the overlapping portion 15 and the overlapped portion 14 is displaced in the width direction in the eaves ridge direction without forming the exterior material 1 in a tapered shape. By installing the roof, a roof having a three-dimensional curved surface or a roof made of a polyhedron can be constructed. Also, the other rising portion 1 of the exterior material 1
2, the overlapping portion 15 is fixed to the overlapping portion 14 above the one rising portion 12 of the adjacent exterior material 1, so that rainwater temporarily drops from the screwed (screw 16) portion. Even so, it is guided on one rising portion 12 and does not cause water leakage to the inner surface of the exterior structure.

In particular, in the illustrated embodiment, since the drain groove 13 is formed outside the portion to be polymerized 14 of the exterior material 1, the portion between the overlapping portion 15 and the portion to be polymerized 14 is temporarily set from the screwing (screw 16) portion. Even if rainwater enters, the water can be prevented from entering further in the drain 13 and no water leaks to the inner surface of the exterior structure.

In the illustrated embodiment, the first engaged portion 121 of the exterior material 1 is provided on the lower jaw 211 of the holding member 2, the inclined surface 122 is provided on the inclined piece of the lower piece 21, and the second engaged portion is provided on the lower member 21. The first engaging portion 121, the inclined surface portion 122, and the second engaging portion 1 of the exterior material 1 are provided on the upper jaw portion 221 in close contact with each other.
The gripping portion formed by 23 is held by the gripping portion formed by the lower jaw 211 and the upper jaw 221 of the holding member 2 from above and below in a squeezed state, that is, gripped from above and below. Therefore, even when stress is applied to the exterior material 1 in the vertical and horizontal directions, the exterior material 1 is held extremely firmly without moving or coming off. Shifting movement due to expansion and contraction in the front-rear direction is also suppressed.

Although the embodiment shown in FIGS. 1 to 3 has a vertical roof structure, the present invention is not particularly limited, and can be applied to various roof foundations such as horizontal roofing, oblique roofing, and three-dimensional specifications. It can be applied as it is. In this case, it is desirable that the overlapping portion 15 of the exterior material 1 on the water side is superimposed on the overlapped portion 14 of the exterior material 1 on the water side in consideration of the rain flow direction on the roof surface and the like. Further, the example in which the overlapped portion 15 and the overlapped portion 14 are fixed with screws is shown, but the present invention is not limited to this, and the overlapped portion 15 and the overlapped portion 14 may be joined with an adhesive or the like. For example, a continuous linear concave portion may be formed in the overlapped portion 14, and an adhesive or the like may be excessively filled in the concave portion to join the overlapped portion 15. The same applies to the attachment of the cover member 5 and the overlapped portion 14 described later.

The embodiment shown in FIG. 4 is the same as the embodiment shown in FIGS. 1 to 3 except that the shapes of the gripping portion of the exterior material 1, the holding member 2, and the inclined legs 32 of the support member 3 are different. Therefore, the same reference numerals are given to the drawings and the description is omitted. That is, the shape and the like of each part of each member are not particularly limited to those described above, and may be any shape. Further, the rising portion 12 of the exterior material 1 is not limited to a substantially inclined shape, but may be, for example, a substantially vertical shape, or a combination of a substantially inclined shape and a substantially vertical shape.

The embodiment shown in FIG.
3 is substantially the same as the embodiment shown in FIGS. 1 to 3 except that a plurality of 3s are provided. That is, as described above, since the drain 13 prevents further intrusion of the infiltration water that has reached between the overlapped portion 15 and the overlapped portion 14, a plurality of such drains 13 are provided. This more reliably prevents water from leaking to the inner surface of the exterior structure.

The embodiment shown in FIG. 6 is substantially the same as the embodiment shown in FIGS. 1 to 3 except that the holding member 2 is separate from the upper and lower parts. . That is, the holding member 2 in this embodiment is composed of a lower holding member 2A, which is the same as the lower piece 21 in FIG. 1, and an upper holding member 2B, which is the same as the upper piece 22 in FIG. A lower jaw 26 is formed on 2A, and an upper jaw 27 is formed on the upper holding member 2B.

The embodiment shown in FIG. 7 is the same as the embodiment shown in FIGS. 1 to 3 except that the lower jaw 321 is formed by welding or the like on the inclined leg 32 on one side (left side) of the support member 3. Since they are almost the same, the same reference numerals are given to the drawings and the description is omitted. That is, the holding member 2 in this embodiment is exactly the same as the upper holding member 2B in FIG.
7 and a lower jaw 321 is formed on the support member 3. In this case, since the number of construction members is smaller than in FIG.
Excellent workability.

In the dome-shaped roof surface shape shown in FIG. 8, part A in FIG. 8A is the ridge side, and as shown in FIG. Is on the eaves side,
As shown in FIG. 9B, the width of the ridge is widened.

The embodiment shown in FIG. 9 is a case in which an exterior structure is constituted by the exterior material 1 and the cover material 5, and the upper ends of both rising portions 12, 12 of the exterior material 1 are respectively substantially folded inward. And the cover portion 5 is formed by extending the cover member 5 so that the cover portion 5 is adjacent to the cover portion 1 of the exterior material 1.
4 and 14 so as to cover the cover material 5 and the portion to be polymerized 14.
And the overlapping position is displaced in the width direction and attached. The cover member 5 of the illustrated embodiment is a substantially horizontal parallel surface member whose both end edges are bent downward, and does not particularly limit the material configuration. For example, the cover member 5 is exemplified in the description of the exterior member 1 described above. Can be used. In the embodiment shown in FIG. 9, not only the one rising portion 12 of the exterior material 1 but also the other rising portion 12 is provided with a holding portion, and the holding portion for holding and holding these from above and below. A member 2 and a support member 3 for supporting the member 2 are provided on the left and right, respectively. That is, since both rising portions 12 of the exterior material 1 are attached to the base 4 by the holding member 2 and the supporting member 3, respectively, basically, the above-described one-sided type embodiment in which only one rising portion 12 is attached. The mounting strength is higher than that of.

In the embodiment shown in FIG. 9, since the cover member 5 is a parallel plane material, it is easy to form the cover member 5 in the eaves ridge direction in the same way as the overlap portion 15 in the one-sided type. The overlapping position may be displaced in the width direction. Further, since one ridge is constituted by the support members 3, 3 disposed on the left and right, the left and right support members 3, 3 may be disposed symmetrically with respect to the center of the ridge. The arrangement interval of the supporting members 3 and 3 with respect to the roof surface is easily set by computer analysis. Further, since the exterior material 1 has a constant width, the arrangement intervals of the two sets of the holding member 2 and the support member 3 to which one exterior material 1 is attached are always constant.

Further, the exterior structure of each of the above embodiments may be a lower roofing layer, and an upper roofing layer may be formed thereon to form a double roof. In this case, the overlapping portion 15 or the cover material 5 of the exterior material 1 serves as a support surface of the roofing layer. In that case, as a roofing layer, a roof of any type and structure may be applied.
The lower roofing layer constituting the double-roofed roof shown in FIG. 10 has a configuration in which the overlapped portion 14 of the exterior material 1 also serves as the second engaged portion 123 in which the upper jaw 221 of the holding member 2 is locked. The overlapping portion 15 is screwed to the overlapping portion 14 via the holding member 2. Also, except that the shapes of the substantially central portion 11 and the eave-side rising portion 12 of the exterior material 1 are different from each other,
The sectional structure is almost the same as that of the embodiment of FIG. 3 (horizontal roof specification).
Therefore, the same reference numerals are given to the drawings and the description is omitted.
Incidentally, reference numeral 222 denotes a rib. As described above, the overlapped portion 15 and the overlapped portion 14 may be attached via the holding member 2. In this case, since the overlapped portion 15 is supported by the holding member 2, the attachment can be performed more securely. And the shape stability of the to-be-polymerized part 14 improves. Although not shown, the cover member 5 and the portion to be overlapped 14 may be similarly attached via the holding member 2. Then, on such an underlaying layer, a roofing roof (horizontal roofing plate 81, rafter 91) having a heat insulating backup material (expanded polystyrene) 71 on the back surface is formed as a roofing layer.

The double-roofed roof shown in FIG.

The double-roofed roof shown in FIG. 12 has a horizontal member (zinc steel plate) 72 as an overlying layer on an underlaying layer having substantially the same sectional structure as that of the embodiment of FIG. 3 (horizontal roofing specification). Along with fixing, a foamed styrene (thick) plate 74, a plywood 75, and a foamed polystyrene (thin) plate 76 are arranged in this order from above, and a core wood (aluminum extruded material) 92 and a roofing material (stainless steel) are placed thereon.
82, and a decorative panel 83 made of stainless steel is further mounted thereon.

In summary, the architectural exterior structure according to the present invention is formed by extending the upper ends of the rising portions of various exterior materials such as vertical roofing and horizontal roofing substantially inwardly to form a portion to be overlapped. The overlapping portion is formed by extending the upper end of the other rising portion outward so as to cover the overlapping portion of the adjacent exterior material, and the overlapping position of the overlapping portion and the overlapping portion. Since it is attached by being displaced in the width direction, it is possible to follow and respond to the roof shape such as a dome or a cone without damaging the roof shape such as a dome or a cone without previously forming the exterior material in a tapered shape according to the roof shape.
Further, even if a mounting error occurs in a holding member or the like disposed on the roof surface, the mounting position of the overlapped portion and the overlapped portion can be adjusted to absorb the mounting error. In addition, since the overlapping portion and the overlapped portion of the exterior material in the exterior structure of the present invention are fixed above the rising portion, rainwater falling from the screwed portion rises even if it is fixed with a screw, for example. Guided to the department. Therefore, in the exterior structure of the present invention, it becomes highly rain-repellent that can be applied to various exterior structures irrespective of the structure of the base, and is also suitable for a roof structure in which, for example, an exterior material is directly installed on a skeleton. Can be used. Further, the exterior structure of the present invention can be a double-roofed roof by forming an underlay layer having a superposed portion of the exterior material or a cover material as a support surface, and applying various over-layers thereon.

Further, the upper ends of both rising portions of the exterior material are extended substantially inwardly inwardly, respectively, to form an overlapped portion, and the parallel-surfaced cover material is connected to the adjacent overlapped portion of the exterior material. The same effect as described above can also be obtained when the cover member and the overlapped portion of the cover member and the overlapped portion are displaced in the width direction so as to cover, and the exterior material and the cover material are tapered according to the roof shape in advance. It is possible to follow and correspond without damaging the roof shape such as the dome and the cone without forming the shape. That is, since the cover material and the exterior material have the same cross section in the eaves ridge direction, a processing time and a processing place (molding space) for forming the tapered exterior material and the tapered cover material are required. Absent. For this reason, special molding is not required when manufacturing the exterior material and the cover material, so that it can be manufactured with the same equipment as before without newly investing equipment, and the manufacturing cost does not increase.

When one or more drainage grooves are formed outside the portion to be polymerized, the drainage grooves prevent further intrusion of the water that has entered between the overlapped portion (or the cover material) and the portion to be polymerized. can do.

By making the rising portion of the exterior material substantially inclined, when the overlapping position of the overlapping portion (or cover material) and the portion to be overlapped is displaced in the width direction, the rising portion is intentionally inclined. Can be fine-tuned.

Further, by using a relatively thick exterior material having a thickness of about 0.8 to 1.6 mm, the strength of positive and negative pressure as a surface can be secured, and the exterior material is laid directly on the frame. It can be suitably used for such a roof structure.
