Description

  The present invention relates to a building exterior structure capable of absorbing an error caused by marking and molding during construction on a normal roof or a tapered roof, and realizing construction that does not require marking.

Inking is to display the line, shape, and dimensions (height, angle, width) necessary for the progress of construction, and the position to attach the suspension (holding member) on the roof surface in roof construction etc. It is necessary to work out ink.
Even in the case of vertical roofs, in the complete fitting method in which the roofing material and the cap material are pressed and fitted from above, high dimensional accuracy is required for the molding of the roofing material and the cap material. Even if the material or the cap material is molded, if the inking operation is not properly performed, the predetermined construction cannot be performed. That is, there is a possibility that an exterior material or a cap material cannot be fitted due to a slight inking error, or an accident occurs that the material is detached after construction.

  In particular, in a taper roof with a spherical or three-dimensional convex curved roof, when the curvature of the roof surface is large with respect to the effective width of the roof plate, an elastic force due to bending acts on the fitting part, so that the construction described above Accidents that came off later became a major problem.

For this reason, the applicant of the present application has a roof structure described in Patent Document 1 having a fixed width roof plate having at least one valley between rising portions on both side edges, and a mountain mounted between the roof plates. The roof structure made of a taper-shaped cover material that forms the part is provided as a roof structure described in Patent Document 2 with a substantially symmetric overlapping and extending part extending outward from the rising part of both side edges. The roof structure in which the exterior material is laid so that the polymerization allowance of the polymerization extension portion is tapered is used as the roof structure described in Patent Document 3, and a double cover material including an adjustment portion that can be displaced in the width direction is used. A thatched roof structure was proposed.
Japanese Patent Laid-Open No. 10-266480 JP-A-10-212797 JP 2001-182226 A

However, the roof structure described in Patent Document 1 only uses a taper-shaped cover material, and requires ink marking like a general roof, and hinders construction depending on molding errors of exterior materials and the like. The same problem occurs.
In addition, the roof structure described in Patent Document 2 can finely adjust the mounting width by making the polymerization allowance of the polymerization extension portion tapered, but an excess polymerization extension portion is provided in advance. Since it is necessary, the member cost is wasted.
Furthermore, the roof structure described in the above-mentioned Patent Document 3 adjusts the degree of opening of the adjustment portion that can be displaced in the width direction formed in a substantially U shape, a substantially V shape, or the like of the cover material. Although fine adjustment is possible, since the adjustment unit itself has an excessive configuration, the member cost is wasted.

  Therefore, the present invention can realize construction that does not require inking without incurring the above-mentioned wasteful costs, and can also absorb errors caused by inking and forming in construction on a tapered roof or the like. The purpose is to propose an exterior structure.

  The present invention has been proposed in view of the above, and is an architectural exterior structure in which a longitudinally wound exterior material is laid and fixed between retaining members installed on a base, and the retaining member is The vertical facing exterior material is provided with a fitting portion that protrudes outward on the left and right side edges, and the vertical facing exterior material of the holding member is fitted to the fitted portion of the holding member. The present invention relates to an architectural exterior structure characterized in that fitting portions are fitted to each other by adjusting an attachment angle, and a cover material is disposed between the longitudinally wound exterior materials.

  In the exterior structure for building according to the present invention, the holding member includes a tower-like portion at the center, an upright standing portion on the left and right sides thereof, and a fitted portion between the tower-like portion and the standing portion. We propose an exterior structure for buildings characterized by this.

  Further, the present invention provides the building exterior structure as described above, wherein the vertical facing exterior material includes a face plate portion at the center, an inner rising portion at the left and right side edges thereof, a water guide groove at the outer side thereof, and an outer rising portion at the outer side thereof, A building exterior structure is also proposed in which a fitting portion is formed by a drainage groove and an engagement portion provided in the outer rising portion.

The building exterior structure of the present invention has an attachment angle when fitting a fitting portion provided in the holding member, which is recessed obliquely downward, and a fitting portion projecting outwardly provided in the vertical facing exterior material. By adjusting and fitting, it is possible to absorb errors caused by inking and molding when performing construction on a normal roof or a tapered roof. In addition, it is possible to achieve construction that does not require ink marking.
And even if there is an error in marking or molding failure of the exterior material, the exterior material and the holding member can be stably fitted, scattering due to poor fit or poor fit after construction, poor fit Therefore, it can be avoided that the exterior material is deformed to impair the design.

  Further, when the holding member includes a tower-like portion in the center, an upright standing portion on the left and right sides thereof, and a fitted portion between the tower-like portion and the upright portion, the holding member has a vertical winding having an inner rising portion described later. When the exterior material is disposed, the face plate portion can be a flow path through which rainwater flows.

  Further, the vertical facing exterior material includes a face plate portion at the center, an inner rising portion at the left and right side edges thereof, a water guide groove at the outer side thereof, and an outer rising portion at the outer side thereof, and is provided on the water guide groove and the outer rising portion. When the fitting portion including the joint portion is formed, when the holding member having the upright portion is disposed, the influence of the fluttering of the face plate portion cannot be exerted on the outside of the inner rising portion, so that the mounting stability is improved. It will be expensive.

  The architectural exterior structure of the present invention comprises a holding member that is fixed on a base, a vertical facing exterior material, and a cover material that is disposed between the vertical facing exterior materials, and the fitting that the diagonally downward provided in the retaining member is recessed. The fitting portion is adjusted to be fitted when fitting the fitting portion and the fitting portion that protrudes outwardly and downwardly provided on the vertical casing material.

The procedure for constructing the building exterior structure constituted by these members is not particularly limited, but as an example, the positions where the holding members 1A, 1B, 1C having the above-described configuration are attached to the base 4 in advance are marked. In addition, the exterior material 2 having the above-described configuration is laid between the holding members 1A and 1A adjacent in the horizontal direction (between 1B and 1B, 1C and 1C).
Then, the fitting portions 25a, 25b, and 25c of the exterior material 2 are fitted to the fitted portions 14A, 14B, and 14C of the holding members 1A, 1B, and 1C by adjusting the attachment angles. At that time, there is no need for any particularly troublesome adjustment operation, and the mounting angle is adjusted and the fitting is performed simply by disposing it from above.

More specifically, as described above, the fitted portions 14A, 14B, and 14C are larger in the order of 14A, 14B, and 14C toward the water side, and are provided outside. 24 is formed so that the elastic drag acts in the outward direction in the laid state, so that it can be fitted by adjusting the mounting angle as described above.
FIG. 1D shows a state in which the fitting portion 25a faces the fitted portion 14A of the holding member 1A, and FIG. 1E shows the fitted portion of the holding member 1B. 14B shows a state where the fitting portion 25b is faced.
Since the fitting portions 25a, 25b, and 25c attached in the respective fitted portions in this way try to return to the direction in which the elastic drag acts and the inclination angle becomes smooth, the smallest fitted portion on the water side. In 14A, the fitting portion 25a has a tilt angle closest to the vertical direction, and in the fitted portion 14C having the largest underwater side, the fitting portion 25c has a tilt angle closest to the horizontal direction.

  Thereafter, the cover material 3 is disposed. As described above, the covering portion 31 is formed inwardly and the leg piece 33 is formed in such a manner that elastic drag acts in the downward direction. By simply disposing, the covering portion 31 is expanded, the engaging portion 32 is engaged with the engaged portion 241, and the leg piece 33 is disposed in contact with the upper end of the inner rising portion 22.

  The architectural exterior structure of the present invention constructed from each of these members is provided with fitted portions 14A, 14B, 14C that are recessed obliquely downward in the holding members 1A, 1B, 1C, and projects outwardly downward from the exterior material 2. Since the fitting portions 25a, 25b, and 25c are provided, the fitting angle is adjusted and the fitting portions are adjusted so that the fitting is performed, and when the taper roof or the like as in the illustrated embodiment is constructed, the ink marking or molding is performed. It is possible to absorb errors caused by

  Moreover, although the illustrated embodiment is a tapered roof, when only one type of holding member is used (without using a plurality of holding members), and an exterior material having the same cross-sectional shape over the length direction is used, For example, since the normal roof shown in the cross-sectional views of FIG. 1 (a) and FIG. 2 (a) is used, a new drawing is not particularly created. It can absorb errors caused by it.

  FIG. 3 shows a side-by-side construction on a normal roof, but the holding member 1 is exactly the same as the holding member 1A on the water side, and the exterior material 2 ′ has the same cross section except that it has the same cross section in the length direction. It is exactly the same as the exterior material 2, and the cover material 3 is exactly the same as that used in the above embodiment.

First, as shown in FIG. 3A, the holding member 1 is assembled in advance on the left side edge of the exterior material 2 ′. In this case, the plurality of holding members 1 are elastically fitted to the back side of the exterior material 2 ′, but it is desirable to temporarily fix them with a double-sided tape or the like so that the holding members 1 do not fall off.
Next, it faces from above the holding member 1 already fixed on the base 4 and is attached on the base 4 as indicated by a black arrow. At the time of attachment, the fitting portion 25 of the exterior material 2 is fitted to the fitted portion 14 of the holding member 1 by adjusting the attachment angle as described above, but no particularly troublesome adjustment operation is required at all. The mounting angle is adjusted as shown in FIG. 3 (b), and the fitting is performed simply by disposing it from above.
Thereafter, the cover material 3 is disposed, but it is elastically fitted and disposed only by being disposed so as to be pressed from above as described above.
Such an operation is continued in succession so that the exterior material 2 'is constructed from the right side to the left side to construct the exterior structure.

  Thus, the exterior structure of the present invention is a so-called piece that is laid from the right side to the left side with the holding member 1 assembled to one side edge (in this case, the left side edge) of the exterior material 2 ′. It is also possible to perform construction by follow-up construction, and it is possible to realize construction that does not require ink marking.
