DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical roofing exterior structure to be installed on a roof or an outer wall of a building which is expected to have a relatively high load load. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing exterior structure and a construction method thereof.

[0002]

2. Description of the Related Art Buildings have no problem in strength under assumed load conditions, and standards such as a Construction Standard Law, a construction order, and a notice of the Ministry of Construction are established so that they can be designed and constructed.
Here, the load condition assumed on the roof of the building will be described. Since most of the positive load depends on the building frame, it is important to consider the load load. Needless to say, the load weight is caused by the wind pressure, but the wind pressure acting on the roof, even in the same exterior surface,
A difference of about three times occurs depending on whether the site is an eave, a keraba, a ridge, or a central site other than the above site.

[0003] Conventionally, in a vertically-roofed roof structure represented by tile-roofing, when the load condition is low, a method is adopted in which the entire surface of the roof is held using a short piece-shaped partial hanger. If the load conditions are high, the roof shingle body may be held in the direction of the eaves ridge using a long sling, or a part where the strength is insufficient in addition to holding the roof shingle body with a partial hanger. For example, a method of fixing a horizontal bar for preventing floating to the vertical bar on the surface of the vehicle is adopted.

[0004]

However, when the whole roof is constructed by using a short piece-shaped partial hanger as described above, no problem occurs under a low load condition, but the strength is insufficient under a high load condition. The problem was that the construction could not be completed. In addition, it is possible to fix the crossbar for preventing the floating from rising to the eaves, the keraba or the ridge where the strength is insufficient, but there is a problem that the external design of the building is significantly impaired.

[0005] On the other hand, in the case of using a through-hook to cope with a high load condition, the strength is naturally sufficient.
There is a problem that excessive performance results in an economic loss. In addition, it is not technically impossible to construct using a partial hanger with an increased strength per fixed point of the partial hanger. However, to increase the strength of the piece member, it is necessary to increase the plate thickness or the number of processes. However, there is a problem that member costs are likely to increase remarkably because the increase in the number of members is indispensable.

BEST MODE FOR CARRYING OUT THE INVENTION A vertical roofing exterior structure according to the present invention generally comprises laying and fixing holding members 3 for holding a vertical roofing exterior material 1 on an exterior base 2 at appropriate intervals.
A long vertical roofing exterior material 1 having a bent portion (12 or 14) held by the holding member 3 at least on both side edges therebetween, and laid in the eaves ridge direction. The holding members 3 having different lengths according to the difference of the blowing wind pressure acting on the holding member 3 are provided.

First, the place where the holding member 3 is laid in the vertical roofing exterior structure of the present invention will be described. Prior to that, the Ministry of Construction Notification No. 109 “Roof based on the provisions of Article 39, paragraph 2 of the Building Standard Law Enforcement Order” According to the criteria for roofing materials, roofing materials and upholstery walls facing the outdoors, the general surface usually has a negative wind power coefficient of 0.5, whereas the length of the exterior surface from the eaves, keraba and ridge respectively The wind coefficient in the range corresponding to 10% of the above (3 m when exceeding 3 m) is 1.5. " Therefore, the present invention is not limited to the roof of a building, but can also be used for upholstered walls to which the above-mentioned standard is applied, for example, vertical wall materials used for forming outer walls. FIG. 1 shows a plan view of the most common gable roof, and the exterior surface (roof surface) is divided as follows according to the size. A range corresponding to 10% of the length in the left-right direction of the exterior surface on the keraba side of the exterior surface (3
m), that is, the outside of the two-dot chain line on the left and right in the figure is the keraba regions 21 and 21. A range corresponding to 10% of the length of the eaves of the exterior surface except for the keraba regions 21 and 21 corresponding to 10% of the length of the exterior surface in the eaves ridge direction (3 m when exceeding 3 m), that is, the two-dot chain line on the eaves side shown in the figure. The eaves side is an eaves tip area 22.
A range corresponding to 10% of the length of the ridge on the exterior surface except for the keraba regions 21 and 21 in the eaves ridge direction direction of the exterior surface (3 m when exceeding 3 m), that is, a two-dot chain line on the ridge side shown in the drawing. The ridge side is a ridge area 23. The exterior surface excluding the keraba areas 21 and 21, the eaves area 22 and the ridge area 23, that is, the inside of the two-dot chain line is a general area 24. In other words, in the above-mentioned rules, "the area corresponding to 10% of the length of the roof surface from the eaves, keraba, and ridge respectively (when exceeding 3m, 3m
The eaves area 22, the kerava area 21, and the ridge area 2
It was set to 3.

The holding members 3 (3A to 3C) having different lengths are provided in each area. In this case, the long vertical roofing exterior material 1 provided has a constant width in the eaves ridge direction. Therefore, the holding members 3 are disposed at a certain interval in the lateral direction. That is, the holding members 3 are arranged on parallel lines at a constant interval.

The first holding member 3A having a length substantially equal to the length of the exterior surface in the eaves ridge direction is provided in the keraba regions 21 and 21.
Is arranged. The first holding member 3A is made of an extruded product made of aluminum, hard resin, ceramic, or the like, or a roll-formed product such as a plated steel plate or a stainless steel plate. In addition, the first holding member 3A may be an on-site integrally molded product having a length substantially equal to the length of the exterior surface in the eaves ridge direction. May be connected as needed.

In the eaves area 22 and the ridge area 23, a second holding member 3B having a length substantially equal to the eaves ridge direction length of the eaves area 22 and the ridge area 23 is provided. As described above, since the eaves ridge direction length of the eaves ridge area 22 and the ridge area 23 is 10% of the eaves ridge direction length of the exterior surface, it is the same,
In both cases, the second holding member 3B is provided. The second holding member 3B is made of the same material as the first holding member 3A. Therefore, there are cases where a plurality of the second holding members 3B are connected to form the first holding member 3A. In that case, the number of members is reduced, which is useful in production, transportation, and site management (storage).

In the general area 24, short third holding members 3C are arranged at appropriate intervals. This third holding member 3C
May be manufactured by pressing a plated steel plate, a stainless steel plate, or the like, but it is preferable in terms of production efficiency to cut the piece formed into a long piece by extrusion or roll forming into a piece-shaped short piece. . In addition, the third holding member 3
C is formed into a size of approximately 50 to 150 mm.

As described above, according to the present invention, the exterior surface is divided into a region under a high load condition (loading region 21, eaves region 22, ridge region 23) and a region under a low load condition (general region 24). ), And using the holding members 3A, 3B, 3C of corresponding lengths, it is possible to rationally and economically construct a vertical roofing exterior structure of a building in which relatively high load conditions are assumed. can do. It is also useful when you want to set a safety factor that greatly exceeds the building standards for the entire exterior surface for the required load conditions.

As shown in FIGS. 2 and 3, even in the case of a similar gable-shaped roof, the fourth holding member, which is longer than at least the third holding member 3C, instead of the first holding member 3A is provided in the keraba area 21. The 3Ds may be arranged in a substantially ladder pattern or a substantially staggered pattern. In these cases, the third holding member 3C is provided in the general area 24. Further, as shown in FIG. 3, the third holding member 3C may be used for adjustment in the fluffy region 21 as well.

[0015] The fourth holding member 3D is approximately 650-1.
000 mm. That is, when the eaves ridge direction length of the exterior surface is 6.5 to 10 m, the fourth holding member 3D and the second holding member 3B may be the same. FIGS. 2 and 3 correspond exactly to this.

Also, as shown in FIGS.
The second holding member 3B may be replaced with a fourth holding member 3D in a substantially ladder pattern or a substantially staggered pattern in the second and ridge areas 23 as well.

As described above, according to the present invention, the first holding member 3
A fourth holding member 3D may be used in place of A or the second holding member 3B. In this case, the vertical-roofing exterior structure can be constructed even more rationally and economically. In particular, in the case of FIGS. 4 and 5 in which the fourth holding member 3D is used instead of the first holding member 3A and the second holding member 3B in the keraba area 21, the eaves area 22 and the ridge area 23, the holding member used is the third holding member. There are two types, the member 3C and the fourth holding member 3D, which are useful in terms of production, transportation, and site management (storage).

FIG. 6 shows a plan view of a roof without a keraba. The roof is divided as follows according to the size of the exterior surface (roof surface). 1 of the length of the eaves on the exterior surface in the direction of the eaves on the exterior surface
A range corresponding to 0% (3 m when exceeding 3 m), that is, the outermost substantially ring-shaped region shown in the figure is the eaves tip region 22. The ridge area 23 is a range corresponding to 10% of the length of the ridge on the exterior face in the eaves ridge direction (3 m when exceeding 3 m), that is, the innermost substantially circular area shown in the figure. The exterior surface excluding the eaves area 22 and the ridge area 23, that is, a substantially donut-shaped area is defined as a general area 24.

The holding members 3 (3B, 3C) having different lengths are provided in each area. In this case, the long vertical roofing exterior material 1 provided from the ridge to the eaves is provided. The holding member 3 has a width that increases at a constant rate.
Are arranged in the horizontal direction at intervals that widen at a fixed rate toward the eaves. That is, the holding member 3 is disposed on radiation at a constant angular interval (11.25 degrees).

In the eaves area 22 and the ridge area 23, the second holding member 3B having a length substantially equal to the eaves ridge direction length of the eaves area 22 and the ridge area 23 is provided. The short third holding members 3C are disposed at appropriate intervals.

As described above, according to the present invention, even on a roof without a keraba, the area under the high load condition (eave area 22, ridge area 23) and the area under the low load condition (general area 24) generated by the blowing wind pressure are applied. ), And using the holding members 3B and 3C having the length corresponding to each of them, it is possible to rationally and economically construct a vertical roofing exterior structure of a building where a condition of relatively high load weight is assumed. Can be. Although not shown, a fourth holding member 3D may be provided in the eaves area 22 or the ridge area 23 in a substantially ladder pattern or a substantially zigzag pattern instead of the second holding member 3B.

Further, according to the present invention, whether the roof 201 shown in FIG.
The present invention can be similarly applied to a dome deformed shape like the roof 202 shown in FIG. 7B or a kamaboko shape like the roof / outer wall 203 shown in FIG. 7C. For example, in order to construct a conical roof 201, the roofing material 1 and the holding member 3 are so arranged that the width direction is a curved surface that is convex upward.
May be used. In addition, in order to construct the dome-shaped roof 201, it is sufficient to use the vertical-roofing exterior material 1 and the holding member 3 that have a curved surface that is convex upward not only in the width direction but also in the eaves ridge direction. Note that, in these cases, the vertical covering material 1 has a width that widens at a fixed rate from the ridge to the eaves as described above. The construction of the dome-shaped roof 202 is the same as the construction of the dome-shaped roof 201, except that the central portion 202 'is provided with the vertical roofing material 1 having a constant width from the ridge toward the eaves. You can use it. In order to construct the kamaboko-shaped roof / outer wall 203, it is sufficient to carry out the same manner as the central portion 202 'of the dome-shaped roof 202.

As described above, in the present invention, four kinds of holding members 3A, 3B, 3C and 3D having different lengths are used in an appropriate combination, and these differences will be described in more concrete illustrated embodiments. Show. The detailed description of each part of the holding member 3 shown in FIGS. 8 to 11 will be described later, but reference numeral 35 is a fixing part to the exterior base. Assuming that the holding member 3 in FIG. 8 is the shortest third holding member 3C, the holding member 3 in FIG. 9 corresponds to the other first holding member 3A, second holding member 3B, and fourth holding member 3D. FIG. 9 omits most of them. FIG.
Is such that it is sufficient to form the fixing portion 35 at two places (although not particularly limited) near both ends in the length direction.
The holding member 3 having a length of about 650 to 1000 mm is shown.
Such a holding member 3 is used as a second holding member 3B and a fourth holding member 3D. FIG. 11 shows the fixing portion 35
The holding member 3 is a long fixed-length member having a length of a few meters, such that a plurality of members need to be formed at appropriate intervals in the length direction (although not particularly limited). Such a holding member 3
Is used as the first holding member 3A by being appropriately connected as necessary. Also, the second holding member 3 is cut into appropriate lengths.
B, the third holding member 3C, and the fourth holding member 3D may be used. Note that the fixing portion 35 may be formed by cutting out a part (upper portion) of the raised portion 33 at the site. Further, depending on the length of the holding member 3, the fixing portion 35 is formed at an appropriate position inside both ends in the length direction as shown in FIGS. As shown in FIG. 11B, there is a case where the fixing portion 35 is formed by cutting out the upper part of the raised portion 33 located at both ends in the length direction.

The arrangement of the various holding members 3 and the like in the present invention have been described above. The following description focuses on the combination (relationship) between the holding members 3 and the vertical roofing exterior material 1. Are described. In addition, in order to avoid duplication of description, the same reference numerals are given to portions that have been described once and their effects even if there is some change in shape, and description thereof will be omitted.

The vertical roofing exterior material 1 used in the vertical roofing exterior structure of the present invention is not limited to other configurations as long as it has a bent portion (12 or 14) held by the holding member 3. Without, it is formed from known metal materials such as surface decorative steel plate, laminated steel plate, plated steel plate, stainless steel plate, aluminum alloy plate, titanium alloy plate, copper plate, brass plate, lead plate, carbon fiber laminate plate, hard resin plate, etc. When the material is a metal plate, it is formed (formed) by roll forming, press forming, or a combination of both. When the material is a non-metal material, it is mainly formed by molding. The thickness of the material is not particularly limited, but is generally about 0.4 to 1.6.
mm. Further, the exterior base 2 in the present invention is:
Wood, steel frame, concrete, etc., all types of building frames to which fixtures such as nails, screws, anchors, etc. can be attached can be used. Wood wool cement boards, etc., laid on the frame as required for heat insulation or other purposes Including boards. Therefore, in principle, a fixing tool for fixing the holding member (lower holding member), except for a case where the boards interposed between the roofing exterior material 1 and the skeleton have the fixing strength of the fixing tool. Are fixed to auxiliary members such as purlins and rafters which form the skeleton by penetrating the boards.

The holding member 3 used in the exterior structure shown in FIG.
The upright portions 31, 31 facing left and right are the upright portions 31,
Flat portions 32, 32 are formed inside 31 and
An upwardly protruding ridge 33 is formed inside the flat portion 32. On the left and right of the raised portion 33, engaged portions 34, 34 elastically engaged with the engaging portions of the vertical covering material 1.
Is formed, and a fixing portion 35 to the exterior base 2 is formed by cutting out a part of the protruding portion 33 in the longitudinal direction.
A top end engaging portion 36 having a substantially circular cross section is formed at the upper end of 3.

Vertical roofing exterior material 1 used in the exterior structure of FIG.
In the figure, a face plate portion 11 is formed in the center, and an upward inner bent portion 12 is formed on the left and right side edges thereof, and an upward outer bent portion 14 is formed outside the inner bent portion 12 through a drain groove 13. It is a configuration to be formed. The inner bent portion 12 is provided with a face plate portion 11.
A space 121 is formed on the back side of the inner part of which is raised at the side edge and an outer part whose upper end is folded downward. The outer bent portion 14
Is formed so as to be inclined outwardly, is provided with an engaging portion 141 that is bent inward and bent outward again in the middle, and has an upper end folded inward. . Also,
An elastic heat-insulating backing material such as polyethylene foam may be stuck or interposed on the back surface of the face plate portion 11 for preventing dew condensation and soundproofing.

The exterior structure shown in FIG. 12 has a structure in which a cap member 4 is mounted between adjacent roofing exterior materials 1 and 1. The left and right edges of the attachment portion 41 have vertical pieces 42, 42 which are bent downward, the lower ends of which are bent inward, subsequently bent downward, and the lower ends are inclined upward inward. It has mounting portions 43, 43 folded in a shape. This cap member 4
Is basically formed from the same material as the vertical roofing material 1, but may be an extruded product made of aluminum or hard resin. The thickness of the material is not particularly limited, but is generally about 1.2 to 2.5 mm for an extruded product. On the back surface of the cap member 4, an elastic heat-insulating backing material such as polyethylene foam is attached or interposed on the back surface of the face plate portion 11 of the vertical roofing exterior material 1, similarly to the back surface of the face plate 11, for preventing dew condensation and soundproofing. Is also good.

The exterior structure shown in FIG. 12 constructed from these members is used for laying the vertical roofing exterior material 1 when the inner bent portion 1 is used.
2 in the space 121 on the back side.
And the engaging portion 141 of the outer bent portion 14 is elastically engaged with the engaged portion 34 of the holding member 3, and the upper end of the outer bent portion 14 is raised to the raised portion 33 of the holding member 3. Is elastically pressed (engaged) with the distal end engaging portion 36 of the second member. Further, the cap member 4 is exposed so as to cover between the vertically roofed exterior materials 1 and 1 which are adjacent in the horizontal direction, and the held portion 43 and the vertically roofed exterior material 1 are covered.
And the cap holding portion (the inside of the engaging portion 141) of the outer bent portion 14 is elastically engaged and held.

The following effects are provided by the various structures employed in the exterior structure shown in FIG.

An upright standing portion 31 is formed on the holding member 3, and the upstanding portion 31 is connected to the inner bent portion 12 of the vertical roofing exterior material 1.
, The displacement in the direction of the center of the working width is suppressed, and the durability is excellent when the wind pressure (load load) is applied and when the snow load (positive load) is applied. . In addition, the upright portion 31 can prevent plastic deformation of a configuration outside the inner bent portion 12 of the roofing exterior material 1,
The function of rain closing and holding relation can be maintained stably.

An engaging portion 141 is formed on the outer bent portion 14 of the roofing exterior material 1, and an engaged portion 34 elastically engaged with the engaging portion 141 is formed on the holding member 3. The holding member 3 allocated and fixed on the exterior base material 2 holds the inner bent portion 12 of the vertically-lined exterior material 1 at the upright portion 31, and furthermore, the outer-folded portion of the vertically roofed exterior material 1 at the engaged portion 34. 14 (engaging part 1
41) can be held. In other words, the vertical covering material 1 can be stably held by the holding member 3, and the position adjustment after the vertical covering material 1 is laid is unnecessary. In addition, since the upper end of the outer bent portion 14 is elastically pressed (engaged) with the distal end engaging portion 36 of the raised portion 33 of the holding member 3, the vertical covering material 1 is firmly held by the holding member 3, The workability is high, and the safety against gusts and the like during construction is also high. Therefore, consideration is given to the increasing public awareness of safety as seen in the enforcement of the PL law in recent years.

The vertical covering material 1 has an upwardly bent inner bent portion 1.
Since the drain 13 is formed on the outside of the eaves 2, even if rainwater that exceeds the inner bent portion 12 occurs due to strong wind or the like, the drain 13 allows the invading rainwater to flow down in the eave direction smoothly and to be discharged from the eaves. It has high rain performance.

The upwardly bent inner portion 12 of the vertical covering material 1
Since the space 121 is formed on the back surface side of the surface plate, even if the thermal expansion and contraction in the width direction acts on the face plate portion 11 due to the solar radiation, it can be absorbed to prevent or reduce the generation of distortion.

The face plate portion 11 of the vertical covering material 1 is
Since it is formed at a position higher than the bottom of 3 and is positioned on or near the neutral axis of the cross-section, even if the exterior base 2 requires curved surface processing to follow a curved building, compression strain may occur. It is easy and beautiful. Further, the vertical covering material 1 includes a face plate portion 11 and an exterior base material 2.
Is formed, the face plate portion 11 does not come into contact with the exterior base 2 (asphalt-based waterproof sheet), and even if the face plate portion 11 becomes hot, the heat is transferred to the asphalt-based waterproof sheet. There is no propagation, and even if the asphalt waterproof sheet is thermally softened, it does not hinder the expansion and contraction action.

The holding member used in the exterior structure shown in FIG. 13 is composed of two members, a lower holding member 6 having a substantially mountain shape and an upper holding member 7 having a substantially umbrella shape. As described above, the holding member may be constituted by a plurality of members, and although not specifically shown, the lower holding member and the upper holding member may each be constituted by a plurality of members. The lower holding member 6 has, inside the standing portion 61, second standing portions 63, 63 having substantially the same height as the upwardly outwardly bent portion 14 of the vertical covering material 1 via the flat portion 62, The portion between the second upright portions 63 serves as a fixing portion 65 to the exterior base 2. Further, a connection receiving portion 6 which is connected to the upper holding member 7 and the connection portion 71 in an engagement manner at the upper end of the second upright portion 63.
6, the length from the corner-shaped engaged portion 64 formed in the connection receiving portion 66 to the inner base portion of the upright portion 61 is the same as the length of the outer bent portion 14 of the vertical covering material 1. Or slightly longer. The upper holding member 7 has, at the center, a connecting portion 71 that fits into the connection receiving portion 66 of the lower holding member 6, and a holding portion 72 that extends outward and downward from the connecting portion 71.
72 extend in an inclined manner. The holding portion 72 has substantially the same length as the outer bent portion 14 of the vertical roofing exterior material, and a substantially wedge-shaped cap holding portion 73 is formed in the middle outside.

The roofing exterior material 1 has a step portion 122 which is widened downward from the middle of the inside piece portion of the upwardly bent inside bent portion 12, and the upwardly bent outside bent portion 14 has a straight cross section. It is.

The cap member 4 is a relatively large curved surface having a semicircular cross section in which the adhered portion 41 is continuous, and substantially also serves as a vertical piece (42). In addition, a holding concave portion 46 for holding the upper half portion of the inside bent portion 12 of the vertical covering material 1 is provided inside the attached portion 41. Further, a through-extruded material 5 that supports a part of the adhered portion 41 of the cap member 4 from below.
Is engaged with the upper part of the upper holding member 7.

In the exterior structure shown in FIG. 13 constructed from these members, the vertical roofing exterior material 1 is laid with the lower holding member 6 fixed to the exterior foundation. Since the upper end of the bent portion 14 is pressed against the engaged portion 64 of the lower holding member 6 and is elastically engaged and held, the upper end of the outer bent portion 14 becomes the engaging portion 141. After that, the upper holding member 7 is slid to connect the connection portion 71 to the connection receiving portion 66 in a fitting manner to be integrated with the lower holding member 6 and to fold the holding portion 72 outside the vertical roofing exterior material 1. It is arranged along the curved portion 14.

As described above, the holding portion 72 that presses and holds the upwardly outwardly bent portion 14 of the vertical roofing exterior material 1 is formed on the upper holding member 7, so that the mounting strength of the vertical roofing exterior material 1 can be increased. Possible, and the workability is also improved. Further, the synergistic effect of the holding portion 72 and the upright portion 61 of the lower holding member 6 improves both the position regulating effect and the deformation preventing effect. Note that the same effect can be obtained by holding the upwardly bent inner portion 12 or the inner base or drainage groove 13 of the vertical covering material 1.

Since the upper holding member 7 is provided with the cap holding portion 73 for elastically engaging and holding the cap member 4 as described above, the product can be manufactured in comparison with the case where the vertical roofing exterior material 1 itself has the cap holding portion. Accuracy and construction accuracy can be improved.

As described above, the cap member 4 is formed with the holding concave portion 44 for supporting the upper half portion of the upwardly bent portion 12 of the vertical covering material 1. Deformation can be prevented or reduced.

The step 122 is positioned at a position higher than the depth of the wet side of the vertical covering material 1 (the surface in contact with the water of the object in the flow rate calculation), and the side edge of the cap member 4 is higher than the step 122. If it is stored at the position, rainwater can be prevented from penetrating from the contact portion between the cap member 4 and the inside bent portion 12 due to the capillary phenomenon. In addition, the step portion 122 makes the lower part of the inner bent part 12 of the vertical covering material 1 and the lower part (side) of the attachment part 41 of the cap member 4 substantially flush with each other, so that the appearance is smooth. Therefore, the design of the bar-shaped portion is improved, and blowing from the contact point due to wind and rain from the girder direction can be reduced. Further, the step portion 122 increases the space 121 corresponding to the expansion / contraction action.

When the through-extruded material 5 is a long material that is continuous in the length direction of the construction surface, even if the cap member 4 is a fixed-length material, waterproof water that does not allow infiltration water from the seam to drop onto the fixing portion 65 is formed. There is a cap effect.

The holding member used for the exterior structure shown in FIG. 14 includes a lower holding member 6 having an upright portion 61 formed by inclining in the working width of the roofing exterior material 1 and an upper holding member 7 serving also as a cap member. And two members. In addition, the upwardly bent portion 12 of the roofing exterior material 1 is in an upright state in a non-combined state, and the inclined upright portion 61 is positioned in the back side space 121 in the combined state in the face-to-face state. The surface plate 11 is inclined toward the side 11, and the face plate 11 becomes concave due to the inclination of the upward bent portion 12.

As described above, the inclined holding portion 61 is provided on the lower holding member 6 with the upwardly bent inner portion 12 of the vertical covering material 1.
, The strength of the upright wind pressure is improved, the displacement of the central portion of the vertical covering material 1 itself is suppressed, and the face plate portion 11 is made concave. Thereby, the pocket wave phenomenon, which is most obvious at normal times, can be made invisible, and the design can be enhanced.

Further, since the upper holding member 7 also serves as the cap member as described above, the upper holding member 7 has higher rigidity than the cap member of the roll-formed product, the holding strength of the vertical roofing exterior material 1 and the bar-shaped portion. The compressive strength can be increased together.

In summary, according to the present invention, the holding members having different lengths according to the difference of the blowing wind pressure acting on the exterior surface are provided. By using three kinds of holding members of the third holding member, and by using two kinds of holding members of the second and third holding members for the exterior surface without the fluff, a condition of relatively high load weight is assumed. The specifications of the entire exterior structure can be optimized.
Conventionally, when the load condition is low, a short piece-shaped partial hanger, that is, the third holding member of the present invention is used, and when the load condition is high, a long through hanger in the eaves ridge direction is used. That is, although the first holding member according to the present invention was used, in each case, only one type of the hanging member (holding member) was used. In contrast to the necessity of fixing the horizontal cross to the vertical cross, there was a problem that the external appearance design was significantly impaired, or there was a problem that the performance was partially excessive, resulting in an economic loss.
As described above, the holding members having different lengths according to the difference of the blowing wind pressure acting on the exterior surface are provided, so that a horizontal bar for preventing floating is not required, and the vertical roof exterior structure of the building. Can be constructed reasonably and economically. It is also useful for setting a safety factor that greatly exceeds the building standards for the entire exterior surface for the required load conditions. Furthermore, although the present invention is directed to a heavy load condition as described above, the present invention is consequently useful under a positive load condition. For example, the roof of a building in a snowy area often has snow stoppers in the eaves area.However, the snow stoppers of a thatched roof are generally fixed at a position equivalent to a vertical bar, and the holding members support the brackets. Therefore, the positive load applied to the snow stopper can be dispersed by the holding member of the present invention.

Further, when a fourth holding member longer than at least the third holding member is arranged in a substantially ladder pattern or a substantially staggered pattern in place of the first holding member or the second holding member, the keraba area or the eaves area is provided. Since the allowable load can be adjusted in a high load area such as a ridge area, a vertical roofing exterior structure can be constructed even more rationally and economically.

The roofing exterior material has a face plate portion at the center, an upwardly bent portion on the left and right side edges, and an outwardly bent portion outside the inner bent portion via a drain groove. The outer bent portion has an engaging portion, and the holding member has an engaged portion that elastically engages with the engaging portion. The vertical roofing exterior structure, which is elastically engaged and held, has a drainage groove formed in the vertical roofing exterior material to smoothly infiltrate rainwater even if rainwater that exceeds the inside bent part is generated due to strong wind etc. Since it can be discharged down the eaves in the direction of the eaves, it has high rain-end performance. Also,
After the holding member is allocated and fixed on the roof foundation in advance,
Since the vertical covering material is laid, there is no need to adjust the position after laying, and the workability is high. Further, since the engaging portion formed on the outer bent portion of the vertical roofing exterior material is elastically engaged with the engaged portion of the holding member at the same time as the laying of the vertical roofing exterior material, the holding strength of the vertical roofing exterior material is high, and the workability is improved. Is also expensive.
