DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the fitting of a horizontal joint when an exterior plate such as a siding is vertically adjacently mounted.

[0002]

2. Description of the Related Art When an exterior panel such as a siding is used as an exterior of a building, a horizontal joint of the exterior panel that is mounted adjacently in the up-down direction must be fitted in consideration of the rain and deformation and expansion / contraction. . FIG. 3 is a cross-sectional perspective view showing a general fitting of a horizontal joint when siding is used as an exterior of a building by a frame wall method. The horizontal joint shown in the figure is a vertical torso rim 5 nailed at predetermined intervals to a structural face material 6 which is an outer wall underlaying material.
Then, sidings 1 and 2 are mounted via a crank-shaped drainer M, and a curtain plate 4 is mounted from above.

[0003]

However, the fitting of such a horizontal joint has the following problems. (1) The drainage hardware M itself is relatively expensive, and the mounting of the drainage hardware M is performed as hardware work separate from the sidings 1 and 2, which causes a cost increase. (2) Since the drainage metal M is in a crank shape having no flexibility, it is necessary to mount the drainage metal M after the lower siding 2 is attached, and then attach the upper siding 1 to the construction. Lack of procedure flexibility. That is, the procedure of mounting the lower siding 2 after mounting the upper siding 1 cannot be adopted, and the range of the process change is restricted, so that it is difficult to shorten the construction period. (3) Since the drainage hardware M is made of inflexible metal, it is difficult to absorb construction errors in the sidings 1 and 2, and it is difficult to reduce the on-site work through the pre-cutting of the sidings 1 and 2. .

Accordingly, the present invention has been made in view of the above problems,
Replacement of drainage fittings with relatively inexpensive materials without the need for additional new construction, as well as flexibility in the construction procedure, and provision of exterior panels that easily absorb construction errors The purpose is to reduce costs, shorten the construction period, and reduce on-site work.

[0005]

That is, according to the first aspect of the present invention, in a horizontal joint in which an upper armor plate and a lower armor plate are adjacent to each other, an upper end portion is located behind the upper armor plate and a lower end portion. Comprises a waterproof paper disposed outside the lower exterior plate, and a curtain plate laid over the upper exterior plate and the lower exterior plate in a state of concealing the waterproof paper from the outside. This is a feature of the outer panel.

[0006] According to the fitting of the exterior plate, the waterproof paper blocks rainwater entering from the horizontal joint as in the case of the conventional water-draining hardware. The construction can be performed in a single step as a part of the same exterior construction as the exterior panel, so that the cost of building construction can be reduced as compared with the conventional case. In addition, since the waterproof paper has flexibility, it is also possible to mount the lower armor plate after mounting the upper armor plate, and it is possible to shorten the construction period by expanding the range of process change. Furthermore, since the waterproof paper has flexibility, it is easy to absorb the construction error of the exterior plate, and it is possible to reduce the on-site work through the precut of the exterior plate.

According to a second aspect of the present invention, in the first aspect of the present invention, a ventilation layer is provided behind the upper outer panel and the lower outer panel, and the waterproof paper is moisture-permeable. And

[0008] According to the housing of the outer panel, the ventilation layer is provided behind the upper and lower outer panels and the waterproof paper is permeable to moisture, so that the moisture generated behind the outer panel passes through the ventilation layer and passes through the waterproof paper. And is discharged to the outside, thereby effectively preventing dew condensation in the wall.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the description, the same elements will be denoted by the same reference symbols, without redundant description.

FIG. 1A is a cross-sectional perspective view showing an embodiment of a housing of an exterior plate according to the present invention, and shows a housing of a horizontal joint when a siding is used as an exterior of a building by a framed wall method. It is a representation. FIG. 1B is a longitudinal sectional view of a main part of FIG. 1A. In these figures, reference numerals 1 and 2 denote siding as an exterior plate, reference numeral 3 denotes waterproof paper, reference numeral 4 denotes a curtain plate, reference numeral 5 denotes a vertical trunk edge as a mounting base for the sidings 1 and 2, and reference numeral 6 denotes a lower part of an outer wall. Reference numeral 7 denotes a structural surface material as an upholstery, and reference numeral 7 denotes a ventilation layer formed by being surrounded by the sidings 1 and 2, the vertical waist edge 5, and the structural surface material 6.

As shown in FIG. 1 (a), the sidings 1 and 2 are mounted on an outer wall structural body composed of structural face materials 6 and the like with the vertical trunk edge 5 as a base. At this time, deformation of each member including siding 1 and 2
In consideration of expansion and contraction, a horizontal joint is formed at a predetermined interval between the lower end of the siding 1 and the upper end of the siding 2. Therefore, waterproofing paper 3 which plays a role similar to that of a conventional drainage is attached to the horizontal joint in consideration of raining so that rainwater does not flow to the back side of the sidings 1 and 2.

The upper end of the waterproof paper 3 has a siding 1
Is mounted between the siding 2 and the curtain plate 4 on the outside thereof. The mounting of the waterproof paper 3 in a state of being bent in a crank cross-sectional shape is based on the same reason as that of the conventional drainage hardware, and as shown by a single-line arrow in FIG. This is to prevent rainwater that has entered from between the siding 1 and the siding 1 from entering behind the sidings 1 and 2.

The reason why the curtain plate 4 is mounted as shown is not only to sandwich the lower end portion of the waterproof paper 3 between the siding 2 and the waterproof paper 3 as described above (see FIG. By concealing from the left side), it is also to improve the appearance of the outer wall and to secure the fire protection of the outer wall. As described above, the role of the curtain plate 4 in the present invention is added in that the role of the conventional curtain plate 4 shown in FIG.

Behind the sidings 1 and 2, there are formed a ventilation layer 7 surrounded by the sidings 1 and 2, the structural face material 6, and the vertical trunk edge 5. This ventilation layer 7 serves to release moisture generated behind the sidings 1 and 2 to the outside air, and as shown by a double-line arrow in FIG. Vertical ventilation is possible. If the waterproof paper 3 is made of a moisture permeable material, moisture can escape to the outside from the outside (indicated by a dotted line in the figure), so that dew condensation in the wall can be more effectively prevented. Note that the ventilation layer 7 is not always provided, but the ventilation layer 7
If the sidings 1 and 2 are not provided, the sidings 1 and 2 are attached to the outer wall structure by appropriate means, and the upper end of the waterproof paper 3 is sandwiched between the siding 1 and the outer wall structure. Need not be permeable to moisture.

When the sidings 1 and 2 are stored as described above, an inexpensive waterproof paper 3 is used in place of the conventional expensive drainage hardware. Unlike the case where the drainage hardware is constructed as the construction, the construction can be performed in one process as a part of the exterior construction at the same time as the siding 1 and 2, so that the cost of the construction work can be reduced.

Next, the procedure for constructing the sidings 1 and 2 as shown in FIG. 1 will be described with reference to FIG. FIG. 2A shows an example in which the upper end of the waterproof paper 3 is sandwiched between the siding 1 and the vertical waist edge 5, and then the lower end of the waterproof paper 3 is positioned so that the lower end of the waterproof paper 3 is outside the siding 2. , The procedure of mounting the siding 2 and mounting the curtain plate 4 while holding the siding. On the other hand, FIG.
(B), the lower end of the waterproof paper 3 is temporarily fixed to the outer upper end of the siding 2, and the upper end of the waterproof paper 3 is held so that the upper end of the waterproof paper 3 comes to the back side of the siding 1. This shows a procedure of mounting the siding 1 and further mounting the curtain plate 4.

As described above, in the present invention, since the flexible waterproof paper 3 is used instead of the conventional drainage fitting,
Not only the procedure of mounting the upper siding 1 after the lower siding 2 as shown in FIG. 2B, but also the lowering of the upper siding 1 as shown in FIG. May be adopted. Therefore, for example, it is possible to cope with the situation where the exterior work on the upper floor is performed earlier than the lower floor by changing the process. Can be achieved.

Further, in the present invention, since the flexible waterproof paper 3 is used instead of the conventional drainage, the distance between the lower end of the siding 1 and the upper end of the siding 2 after the construction is larger than the design dimension. Waterproof paper 3 large or small
By adjusting the tilt angle around the middle of As described above, since the use of the flexible waterproof paper 3 makes it easy to absorb the construction error of the sidings 1 and 2, it becomes easy to cope with the pre-cutting of the sidings 1 and 2, thereby reducing on-site work. Can be planned.

In this embodiment, the horizontal joints are shown in the case where the siding is used as the exterior of the building by the framing wall method. However, the present invention is not limited to this. Regardless of the structure type and construction method. For example, the present invention can be applied to a conventional wooden or reinforced concrete building, and can be applied to a case where an exterior plate other than siding is used.

[0020]

As described above, according to the first aspect of the present invention, the waterproof paper blocks rainwater entering from the horizontal joint as in the case of the conventional drainage hardware. In addition to being inexpensive, the construction of waterproof paper can be performed in one step as part of the exterior construction same as the exterior panel, so that the cost of construction work can be reduced as compared with the conventional case. In addition, since the waterproof paper has flexibility, it is also possible to mount the lower armor plate after mounting the upper armor plate, and it is possible to shorten the construction period by expanding the range of process change. Furthermore, since the waterproof paper has flexibility, it is easy to absorb the construction error of the exterior plate, and it is possible to reduce the on-site work through the precut of the exterior plate.

According to the second aspect of the present invention, the ventilation layers are provided behind the upper and lower outer panels and the waterproof paper is permeable to moisture, so that the moisture generated behind the outer panels passes through the ventilation layers. Thus, the water passes through the waterproof paper and is discharged to the outside, so that dew condensation in the wall can be effectively prevented.
