DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building exterior material and an exterior structure of a building used for a building in which peaks and valleys are alternately formed in a construction state.

[0002]

2. Description of the Related Art Conventionally, as an exterior material used for a building in which peaks and valleys are alternately formed in a construction state,
There are exterior materials called folded plates and tile rods, and the connection type is mainly bolt-tight or goby-tight. However, in recent years, from the viewpoint of the shortage of construction workers and the improvement of the working environment, an elastic fitting type, which has excellent workability, has been shifting. As the exterior structure connected by the elastic fitting, there is a practically open flat type 6-79.
925 and Japanese Patent Application Laid-Open No. 6-117061. Both of these proposed exterior structures include a concave fitting provided on the upper edge of the left and right rising portions of the exterior material in a convex fitting portion of a fixing bracket (exterior material holding member) provided in a tight frame or the like. The joint is elastically fitted. An exterior material having a concave fitting portion used for this exterior structure is:
Since the upper side wall portion bears the positive load and the lower side wall portion bears the load, the strength is superior to the fitting type exterior material having only the lower side wall portion. The strength of a general elastic fitting type exterior structure is proportional to the strength of the fitting, but the fitting operation tends to be the opposite. That is, when the thickness of the material of the exterior material is reduced or the fitting relationship with the fixing fitting is loosened, the fitting work is improved, but the strength of the structure is reduced. Conversely, when the thickness of the material of the exterior material is increased or the fitting relationship with the fixture is tight, the workability is relatively reduced, but the strength of the structure is improved. In general, the fitting operation is performed by a worker adjusting the mutual position of the exterior material and the fixing bracket and stepping on the foot. At this time, since the worker located above the exterior material cannot visually see the fitted portion of the fixing bracket, the positional relationship is specified by a tactile sensation while sliding the exterior material up and down.

[0003]

However, the conventional elastic fitting type exterior material as described above has the following problems.・ Since it is configured to fit so that the concave fitting part of the exterior material covers the convex fitting part of the fixing bracket, even if the mutual positional relationship is not appropriate, the mistake is not noticed. Work is often continued. In other words, the worker easily misunderstands that the fitting is tight even though the mutual positional relationship is not appropriate, so that an excessive load is applied by, for example, kicking in a place to be stepped on with a foot. I will.
In general, since the exterior material is thin and has low strength with respect to the fixture, the side wall portion of the fitting portion is easily deformed by the operation of the excessive load. -Since the exterior material deformed by the inappropriate work cannot be used as it is, a repair work is required, and as a result, the originally intended high workability may not be obtained.・ If the deformation is extremely severe, it is difficult to repair, so you will have to use a spare exterior material, but if this spare exterior material is not prepared enough, it will be necessary to reproduce it. The construction period may be adversely affected. The improper work is unlikely to occur by making the thickness of the material of the exterior material thinner than the normal thickness of 0.6 to 1.2 mm or broadening (loosely) the fitting relationship. The means directly reduces the strength of the exterior material and the exterior structure, and is not practical as a technical solution at all. Also, a number of basic fitting modes are known in which the exterior material is vertically dropped into the holding member, and at the same time, the concave fitting portion of the exterior material is fitted to the holding member. Although there is no problem when a positive load is applied, when a load is applied, the force in the mounting direction and the force in the dismounting direction are almost directly opposed, and there is a high possibility that the force is released with almost the same force as the mounting load during construction. Furthermore, there are many known structures in which the exterior material is dropped vertically and fitted to the inclined surface in a substantially vertical direction.
When a positive load or a load is applied, only one contact of the fitting portion bears the load, and cannot withstand a large load. Further, a structure in which a plurality of contacts can be obtained by providing a constricted portion in a concave fitting portion is also known, but as described above, the exterior material is thin and easily deformed as compared with the holding member. There are problems caused by this.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an exterior material 1 according to the present invention generally has a face plate portion 2 in the center and inclined rising portions 3 and 3 on the outside. It is a configuration in which a bulging fitting portion 31 having a constricted portion 311 on the outside is formed at an angle substantially orthogonal to the inclination in the middle of the direction, and peaks and valleys are formed alternately in the connected state. Things. The exterior material 1 forms an exterior structure together with the exterior material holding member 5 fixed on the exterior base 4 as shown in FIG.

The exterior material 1 is not particularly limited in its material, but typically has a surface decorative steel sheet, a laminated steel sheet, a plated steel sheet, a stainless steel sheet, an aluminum alloy sheet having a thickness of about 0.4 to 1.6 mm. A known metal material such as a titanium alloy plate or a copper plate is formed into a predetermined shape by roll forming or other means. It is to be noted that a similar shape can be formed by using a hard resin plate, a carbon fiber laminate plate, or the like, and that all of them can be constructed with them, or can be constructed in combination with the above-mentioned metal material. Also, 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. The exterior material 1 shown in FIG. 1 is, specifically, a folded-plate roof plate having inclined rising portions 3, 3 raised about 60 degrees outside a substantially flat face plate portion 2. In the middle of the rising portion 3 in the height direction, a fitting portion 31 bulging into a substantially cylindrical shape having a constricted portion 311 at a base end is formed outside at an angle substantially perpendicular to the inclination. I have. still,
The fitting portion 31 is scissored to form the upper rising portion 3 as a rising upper portion 32 and the lower rising portion 3 as a rising lower portion 33.
The (bulged) shape of the fitting portion 31 is not particularly limited as long as it can be smoothly inserted into the fitted portion 51 of the exterior material holding member 5 described later. It can be formed in a spade shape, an elliptical shape, a perfect circle shape, a wedge shape, or the like. The fitting portion 31 of the illustrated embodiment has a shape in which one corner of a square tubular shape is opened, and is formed to extend on a support surface 331 formed by bending an upper end of a rising lower portion 33. The opening edge of the formed open portion 312 is a narrowed portion 311, and the top facing the open portion 312 is a tip portion 313. The open portion 312 is a space that allows the narrowed portion 311 to be elastically displaced and the fitting portion 31 to be reduced in width, but the fitted portion 51 of the exterior material holding member 5 is elastically deformed. Only in the case of a possible configuration, this open portion 312 is not necessary, and after all, the fitting portion 31 may be substantially closed. Further, an upright mating piece 321 is formed at the tip of the rising portion 3 (the rising upper portion 32).

The exterior material holding member 5, which constructs the exterior structure shown in FIG. 2 together with the exterior material 1, basically has at least a fitted portion 51 elastically fitted with the fitting portion 31. In addition, conventionally known members such as hangers and tight frames, and a combination of a plurality of members are also included. The material for the exterior material holding member 5 may be appropriately selected according to the size of the exterior material 1 and the required strength.
It is formed by pressing a stainless steel plate or a plated steel plate of about 2 mm or the like. The exterior material holding member 5 used in the exterior structure shown in FIG. 2 is made up of three pieces (5A, 5A, 5B) formed by bending a relatively thick short width material, and two pieces are the same. A shaped upper member 5A,
It is a substantially U-shaped member in which a vertical upright piece 53 and a V-shaped vertical piece 54 are raised from both ends of a horizontal piece 52. Standing piece 5
Folded pieces 531 and 541 extending inward and downward respectively extend from upper ends of the third piece 3 and the vertical piece 54. The lower member 5B to which the upper member 5A is attached has a shape in which a horizontal receiving piece 55 and a fixing piece 56 along the exterior base 4 are connected by inclined leg pieces 57, and the horizontal receiving piece 55 and the inclined leg piece 57 The table-shaped crest has a trough formed by the fixing piece 56 and the inclined leg piece 57, and also serves as the lower member 5 </ b> B of the adjacent exterior material holding member 5. Then, the horizontal piece 52 of the upper member 5A and the horizontal receiving piece 55 of the lower member 5B are integrally fixed by appropriately joining together by means (connecting tool 58). The two-piece upper members 5A, 5A are
The three were fixed so that they were back to back. The gap (introduction gap 511) between the lower end of the folded piece 531 and the upper end of the vertical piece 54 in the exterior material holding member 5 is equal to the gap (opening portion 312) of the narrowed portion 311 of the fitting portion 31 of the exterior material 1. ) Is formed at substantially the same interval as that of FIG.

The exterior base material 4 for fixing the exterior material holding member 5 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, or a configuration in which a steel frame or a wood hut is laid on a concrete frame, The exterior material holding member 5 may be directly attached to the concrete surface whose foundation has been adjusted. Therefore, the exterior base 4 to be applied in the present invention is:
Includes all building frames to which the exterior material holding member 5 can be attached by various fixing means such as nails, screws, anchors, welding, etc., and heat insulation or other wool cement laid on the frame as required. It includes boards such as boards.

The exterior structure shown in FIG. 2 has a configuration in which a cover material 6 that covers adjacent exterior materials 1 and 1 and that also covers the open portion 312 of the fitting portion 31 on the right and left side edges is attached. The cover member 6 has a configuration in which a lower covering portion 63 is formed on the left and right sides of the mountain-shaped upper covering portion 61 so as to extend slightly outward and downward through a pair of left and right held portions 62. At the front end of the lower covering portion 63, an attached portion 631 that is further deeply inclined is provided.

The construction of the exterior structure according to the present invention is generally performed by placing the exterior material holding member 5 on a steel frame base 4 such as a beam, a purlin, or a rim.
Is mounted, and the exterior material 1 is attached to the exterior material by elastic fitting. A more detailed construction situation will be described below. First, the exterior material holding member 5 having the above-described configuration is attached on the exterior base 4 in advance, and FIG.
The exterior material 1 is made to face between adjacent exterior material holding members 5 and 5 as shown by a solid line on the left half side of (b). Next, when the lower portion is lowered as it is, as shown by a dotted line, the lower portion slides down in a state where the distal end portion 313 of the fitting portion 31 is in contact with the upper surface of the folded piece 531 of the exterior material holding member 5. ,
The rising portions 3 (31, 32, 33) are urged in the vertical direction against the elasticity. The exterior material 1 is supported by the end of the face plate portion 2 (the base end of the rising lower portion 33) abutting on the inclined leg piece 57 of the exterior material holding member 5, and the introduction gap 511 of the fitting portion 51. Is in a state in which the fitting portion 31 is facing so as to close. Next, when the fitting portion 31 of the exterior material 1 is pressed as shown by a dotted line on the right half side of FIG. 2B, the rising portion 3 tilts with its lower end as a center point, and A, B, and C in order. In the state, finally, it is elastically fitted to the fitted portion 51 of the exterior material holding member 5. During this process, particularly in the states A to B, the fitting portion 31 is narrowed and deformed so as to have the same outer diameter as the introduction gap 511, and the narrowed portion 311 is elastically displaced and narrowed. In the state C, the fitting portion 31 is elastically restored, and the narrowed portion 311 is located in the introduction gap 511 and is firmly held. Note that, in this process, the distal end portion 313 of the fitting portion 31 performs an arc-shaped displacement indicated by the illustrated arrow.
2, a jig (not shown) having a rod-shaped or blade-shaped projection is inserted, and the inner surface of the tip portion 313 is pressed so that the fitting portion 31 is elastically fitted to the fitted portion 51. May be. In this way, the exterior material 1 is attached to the exterior material holding member 5, and the lower part of the rising lower part 33 of the exterior material 1 is on the inclined leg piece 57 , and the support surface 331 of the rising lower part 33 is on the upper end of the vertical piece 51 , respectively. Supported. Then, the cover member 6 is attached to cover the adjacent exterior members 1 and 1 and to cover the open portion 312 of the fitting portion 31 at the left and right side edges. In this case, the held portion 62 of the cover member 6 is
, The elastic member is elastically engaged with the folded piece 531 of the exterior material holding member 5, and the tip of the lower covering portion 63 is attached to the support surface 331 of the exterior material 1, so that the inner space of the upper covering portion 61,
The space surrounded by the lower cover portion 63 and the fitting portion 31 is closed, and the decompression space 7 is formed. The connecting portion between the rising portions 3 and 3 of the adjacent exterior material 1 is a mountain portion, and the exterior material 1 is connected.
Face plate 2 forms a valley.

In the exterior structure constructed in this manner, peaks and valleys are alternately formed in the construction state.
Since the convexly bulging fitting portion 31 formed on the exterior material 1 is fitted to the concave fitting portion 51 of the exterior material holding member 5,
The alignment is easier than when a conventional concave fitting portion is fitted. For example, if the fitting portion 31 is in a state of contacting the rising lower portion 33 or the rising upper portion 32, almost no elasticity is felt even when pressed, but is pressed in a state facing the fitted portion 51 (a loosely fitted state). Then, the user feels elasticity and can easily recognize at least the state in which it is not in contact with the rising lower part 33 or the rising upper part 32. In addition, even if there is some misalignment in the positional relationship between the fitting portion 31 and the fitted portion 51, if the pressing is performed in this state, the exterior material 1 automatically shifts to a regular position, so that the fitting portion 31 can be easily moved. 31 can be guided to the fitted portion 51. Further, when the operator performs the above-mentioned fitting operation,
Even if an excessive load is applied to the
1 has a high strength by exhibiting a pipe shape, and therefore is not easily deformed. Therefore, the exterior structure of the present invention can significantly suppress the occurrence of deformation as compared with the exterior structure of the conventional configuration, and achieves high workability of the fitting type exterior material 1 stably. Become. In addition, the fitting portion 31
Has a pipe shape, so that the exterior material 1 does not incline outward due to its own weight or the like even between skeleton spans where there is no fitted portion (exterior material holding member), so that the effect of suppressing the displacement in the width direction is achieved. Can also be expected.

Further, in this exterior structure, the cover material 6 that covers the adjacent exterior materials 1 and 1 and covers the open portion 312 of the fitting portion 31 at the left and right side edges is attached, so that the decompression space 7 is stable. Is obtained. The depressurized space 7 prevents the capillary phenomenon and suppresses the infiltration of rainwater. Even if it does so, the fitting portion 31 functions as a gutter and flows down reliably, so that high rain performance can be obtained.

Further, since the fitting portion 31 in the illustrated embodiment has a shape in which one corner portion of a rectangular tube is opened, the formability and the fitting workability are lower than those in the case of forming into another polygonal tube. Excellent in balance. For example, a fitting portion having a triangular cylindrical shape with one corner opened is easy to form, but the fitting operation is extremely difficult (substantially impossible) because the large diameter portion is the insertion tip. Therefore, it is preferable that the insertion distal end of the fitting portion 31 of the present invention is not a maximum width portion but has a sharp shape so as to facilitate the insertion operation.

The exterior material 1 used for the exterior structure shown in FIGS. 3 and 4 has a configuration in which an engaging portion 332 projecting in a V-shape is provided in the middle of the rising portion 33. The exterior material holding member 5 used in this exterior structure is the same as the exterior material holding member 5 used in the exterior structure shown in FIG.

This is a configuration in which a cover portion 34 that covers the other edge is integrally formed on one edge. Specifically, one (right side in the drawing) rising upper part 3
2, a mountain-shaped cover portion 34 extending to cover the other rising portion 32 is extended, and the upper end of the rising portion 3 (rising portion 32) of the exterior material 1 on the other side (the left side in the drawing) is set to the upper member 5 </ b> A.
It was located between the standing portions 53 of 5A. Then, the held portion 341 formed in the cover portion 34 was elastically engaged with and connected to the folded piece 531 of the exterior material holding member 5 via the fitting portion 31. Structures other than these are the same as those in the exterior structure of FIG. 2 described above, and the same reference numerals are given and description thereof is omitted.

In the exterior structure shown in FIG. 5, there is no need to provide the cover member 6 as in each of the exterior structures shown in FIGS. 2 to 4, so that the effect of reducing the number of members in material procurement, transportation management, construction man-hours, and the like can be obtained. can get.

The exterior material 1 used for the exterior structure shown in FIG.
As in the case of the exterior structure shown in FIG.
4 is formed integrally. Specifically, instead of one (right side in the drawing) rising upper part 32, a mountain-shaped cover portion 34 covering the other rising part 32 is extended, and the other (left side in the drawing) rising part 32 of the exterior material 1 is extended. A bent piece 36 that is bent outward is provided at the upper end of the. The other rising portion 32 and the bent piece 36 are covered with the cover part 34, and the held part 341 formed on the cover part 34 is elastically attached to the folded piece 531 of the exterior material holding member 5 via the fitting part 31. And connected. The exterior material holding member 5 used in this exterior structure has a standing piece 53 extending outward in place of one upper member 5A among the exterior material holding members 5 used in each of the exterior structures in FIGS. And bent upwards to engage the locking portion 53
This is a configuration using the upper member 5A ′ on which the second member 2 is formed. still,
The bent portion 36 provided on the exterior material 1 on the left side of the drawing is locked to the locking portion 532. Structures other than these are the same as those in the exterior structure of FIG. 2 described above, and the same reference numerals are given and description thereof is omitted.

In the exterior structure shown in FIG. 6, the exterior material 1 on the left side of the drawing is held by the exterior material holding member 5 not only with the fitting portion 31 and the engagement portion 332 but also with the bent piece 36. The resistance to a positive load is higher than that of the exterior structure of FIG.

The exterior material 1 used for the exterior structure shown in FIG.
A fitting portion 31 having a spade-like cross-sectional shape is formed,
A pair of left and right cover material holding portions 322 for engaging the held portions 62 of the cover material 6 by folding the upper ends of the fitting pieces 321 in an inclined manner toward the face plate portion 2 were formed. The fitting portion 31 in this exterior structure is provided below the fitting portion 31 in each of the exterior structures in FIGS. 3 to 5, and is located substantially at the center of the height of the rising portion 3. In addition, the exterior material holding member 5 used in the exterior structure has a U-shape formed by punching a flat plate material instead of the upper members 5A, 5A formed by bending a relatively thick short width material. Upper member 5 formed by bending into
C is integrally fixed to the lower member 5B ″ in which the inclined leg piece 57 is long. The fitted member 31 elastically fitted to the fitting portion 31 of the exterior material 1 having a spade-shaped cross-sectional shape. Part 51
Is formed as a blanking portion in the upper member 5C. The outer shape of the upper half of the upper member 5C is formed to be substantially the same as the cross-sectional shape of the rectangular-shaped rising upper portion 32. In the description of the fitting portion 31 of the exterior material 1, the fitting portion 31 may be substantially closed only when the fitted portion 51 of the exterior material holding member 5 is configured to be elastically deformable. Although it was explained that it is good, for example, an elastic material such that at least the fitting portion can be fitted and the introduction gap is smaller than the maximum width portion of the fitting portion on the inner surface of the large gap formed in the hard material. In the case where it is attached, the fitted portion 51 is configured to be elastically deformable. The cover member 6 includes only an upper cover part 61 and a held part 62 that cover the space between the adjacent exterior materials 1 and 1. Structures other than these are the same as those in the exterior structure of FIG. 2 described above, and the same reference numerals are given and description thereof is omitted.

In the exterior structure shown in FIG. 7, since the expanding guide portion 512 is formed outside the introduction portion 511 of the fitted portion 51, the fitting portion 31 of the exterior material 1 is fitted. In this case, the positioning can be easily performed, and the guiding can be reliably performed by the fitted portion 51. Further, since the fitting portion 31 is provided so as to be located substantially at the center of the rising portion 3, even if the engaging portion 332 is not provided as in each of the exterior structures of FIGS. The resistance to is high.
Further, in each of the exterior structures shown in FIGS. 2 to 4, the cover material 6 is attached to the exterior material holding member 5 via the fitting portion 31. However, as shown in FIG. (322)). In this case, the article processing becomes easier as compared with the case where the cover material holding portion is provided on the exterior material holding member 5.

The exterior material 1 used for the exterior structure shown in FIG.
As in the case of the exterior material 1 shown in FIG. 5, a cover portion 34 covering one edge is integrally formed on one edge. Specifically, a substantially fan-shaped cover part 34 is provided at the upper end of one (the right side in the drawing) rising part 32, and the rising part 3 (the rising part 32) of the exterior material 1 (the left part in the drawing) is extended. At the upper end, a covering portion 35 composed of a vertical piece and an inclined piece was extended, and a V-shaped cover holding portion 351 was formed on the covering portion 35. The held portion 341 formed on the cover portion 34 is elastically engaged with the cover holding portion 351 formed on the covering portion 35 to be connected. The configuration other than these is the same as in FIG.
And the same reference numerals are given and the description is omitted.

In addition, in each of the exterior structures shown in FIG. 5, the cover portion 34 is attached to the exterior material holding member 5 via the fitting portion 31, but as shown in FIG. 8, the exterior material 1 (the cover holding portion 351) is provided. You may be made to attach to. In this case, the article processing is easier than in the case where the cover holding member is provided on the exterior material holding member 5.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and may be implemented in any manner unless the structure described in the claims is changed. Can be implemented. For example, in the drawings of the embodiments, known waterproof materials such as asphalt roofing and asphalt felt are not shown, but they do not hinder their use. In the case where a fiber-based heat insulating material or the like is laid on the exterior base, it is preferable that the heat insulating material be stretched from the viewpoint of curing. In addition, the face plate portion of the exterior material of the present invention may be subjected to soothing wave processing as necessary, or may be formed with a bent portion below the rising portion in the middle. Furthermore, in the illustrated embodiment, the exterior material holding member has a two-piece or three-piece configuration, but may have a one-piece configuration.

[0026]

In summary, the building exterior material of the present invention is
When the conventional concave fitting part is fitted when fitting the concave fitting part formed on the exterior material holding member because the fitting part bulging in a convex shape is provided. Alignment becomes easier as compared with. Further, even if there is a slight deviation in the positional relationship between the fitting portion and the fitted portion, the fitting portion can be easily guided to the fitted portion. Further, even if an operator exerts an excessive load when pressing the fitting portion, the bulging fitting portion has a high strength by being formed in the shape of a pipe, and thus is hardly deformed. Therefore, as compared with the configuration of the conventional fitting type exterior material, the occurrence of deformation can be significantly suppressed, and the fitting operation can be performed stably.

Further, since the fitting portion has a pipe shape, the exterior material does not incline outward even between the frame spans where the fitting portion does not exist, so that the effect of suppressing the displacement in the width direction can be expected. . In addition, since the fitting portion in the present invention is formed at an angle substantially orthogonal to the inclination in the middle of the height direction of the rising portion, the fitting relationship with the fitted portion is a basic relationship of a positive load and a load weight. Since it is oblique to the direction (up and down) of the force, the fitting (mounting) direction and the direction of the external force do not face each other. Therefore, when the force at the time of attachment and the external force are equal, the fitting does not come off due to the external force. Furthermore, since the fitting portion has a bulging shape having a narrowed portion, a plurality of contacts can be obtained in relation to the corresponding fitted portion even when external forces in both the upper and lower directions act, and both contacts are as described above. Since it is not easily deformed, high strength can be obtained as compared with the conventional configuration.

In particular, when a cover part for covering the other edge is formed integrally with one edge of the exterior material, there is no need to prepare a separate cover material, so that the number of members is reduced in material procurement, transportation management, construction man-hours and the like. The effect is obtained.

In the case where a cover material that covers adjacent exterior materials and also covers the open portion of the fitting portion at the left and right side edges is applied to form a closed depressurized space, a function to prevent the capillary phenomenon is included. The reduced pressure space can be obtained stably. This decompression space prevents the capillary phenomenon and suppresses the infiltration of rainwater,
Even if it penetrates, the fitting portion functions as a gutter and flows down reliably, so that a high rain performance can be obtained. In addition, the infiltration water also ensures that it flows down in the reduced pressure space,
It has high rain performance.
