Description

TECHNICAL FIELD The present invention relates to exterior wall panels used for building exterior walls.

Conventionally, as a form of joining external wall materials of ceramic siding, there is known a sealing-less construction method that makes joints inconspicuous in appearance and improves design. As a sealing-less construction method, the joint edge of the two exterior wall materials to be joined is processed with a seawall, and a joiner (joining accessory) is used at the joint to create a seal inside the exterior wall so that it is not exposed to the outside. (See, for example, Patent Document 1)

When carrying out the construction method described in Patent Document 1, of the two exterior wall materials to be joined, one of the exterior wall materials on one side of which the joint edge has been subjected to backing lathe processing is used. On the other hand, in the case of using a sealing construction method with better sealing performance, an exterior wall material without interlocking is used. It is difficult to join using the exterior wall material described in Patent Document 1 in terms of construction of the sealing method. This is because the edges of the outer wall material are subjected to backing lamination processing, making it difficult to enclose the sealing material in the joints.

In the construction of building exterior walls, the above-mentioned sealing method and sealing-less method may be used in combination depending on the location, but it is difficult to use exterior wall materials together, and it is necessary to prepare dedicated exterior wall materials for both. Therefore, it is necessary to manage the number of each material according to the design specifications of the building, and to distinguish the outer wall material for each construction method by the construction worker at the construction site. It is a burden in material management and construction work.

Japanese Patent No. 5541903

In order to solve the above problems, it is desired to develop exterior wall materials that are compatible with both sealing and non-sealing methods. According to such an exterior wall material, only one type of exterior wall material needs to be prepared, and there is no need to distinguish between different exterior wall materials during construction, which reduces the burden of material management and construction work. In addition, it is possible to prevent human errors such as mistaking panels when distinguishing exterior materials.

The present invention has been made in view of the above, and it is an object of the present invention to provide an exterior wall panel that can be used in combination with both the sealing method and the non-sealing method in the installation work of ceramic siding used on the outer wall of a building, and its installation structure. .

Embodiments of the present invention will be described below, but the present invention is not limited to the following embodiments.

<First embodiment>
As a first embodiment of the present invention, a first installation structure 100 for a building outer wall shown in FIG. 3 will be described below.

The first installation structure 100 includes a square plate-shaped outer wall panel 1 having a right vertical side formed with a backing hole portion 10 and a left vertical side formed with a vertical end face without step processing, and a backing hole portion 10 . a plate-like protrusion 23 inserted into the outer wall panel 1, and joins the two outer wall panels 1 with the backing shell 10 of one outer wall panel 1 and the longitudinal end surface of the other outer wall panel 1. This is an installation structure for a building outer wall by a sealing-less construction method, comprising an object 2 and a sealing material 24 covering both sides of a plate-shaped protruding part 23 .

In the first installation structure 100, the two outer wall panels 1 are joined by the first joining accessory 2 at the joining portion between the backing shell portion 10 of one outer wall panel 1 and the longitudinal end face of the other outer wall panel 1. ,
A protrusion 23 and sealant 24 are inserted into the backing shell 10 to form a sealing surface at the joint.

FIG. 1 is a horizontal cross-sectional view of an exterior wall panel 1 of the present invention.
The outer wall panel 1 is a square plate-shaped outer wall panel having a backing seam portion 10 formed on the right vertical side and a vertical end face without step processing formed on the left vertical side. As a material constituting the exterior wall panel 1, a ceramic siding that is generally used for exterior wall panels of buildings is used. Although the upper and lower sides are not particularly limited, the upper and lower sides may also be formed with seawalls so that a plurality of exterior wall panels 1 are arranged vertically and installed by a sealingless construction method.

In the outer wall panel 1, the lateral width of the backing shell 10 is designed to be narrower than that of the shell formed in the outer wall panel for the conventional sealingless construction method, and is used for the first joining function described later. It is larger than the plate thickness of the plate-shaped protruding portion 23 of the object 2 and equal to or less than the sum of the plate thickness of the protruding portion 23 and the thickness of the sealing material 24 . Specifically, it is preferably 0.5 to 6.0 mm.

As a result, when the two exterior wall panels 1 are joined together, the protruding portion 23 and the sealing material 24 are inserted between the backing shell portion 10 of one of the exterior wall panels 1 and the stepless longitudinal end surface of the other exterior wall panel 1. It becomes possible and the joint of the two outer wall panels 1 is sealed. Further, since the width of the backing shell 10 is formed narrow, even when it becomes necessary to carry out the backing shelling process on site, the backing shell 10 can be formed only by shallowly notching the outer wall panel. It can be processed more easily than before.

FIG. 2 is a horizontal cross-sectional view of the first joining accessory 2. As shown in FIG.
In the first installation structure 100, the first joining accessory 2 is formed by performing step processing on two laterally adjacent outer wall panels 1 with the backing shell portion 10 of one outer wall panel 1 and the step processing of the other outer wall panel 1. Used for joining with non-existent longitudinal edges.

The first joint accessory 2 is a metal part extending vertically along the vertical side of the outer wall panel 1, and includes a plate-shaped base 20 and two parts of the same length extending vertically from both ends of the base 20 to one side. It is interposed between the water stop portions 21 and 22 and the two water stop portions 21 and 22, and is longer than the two water stop portions 21 and 22 in parallel with the two water stop portions 21 and 22 from the base portion 20. and an extending plate-like protrusion 23 . A sealing material 24 is provided at the tip of the projecting part, and is interposed between the two outer wall panels 1 to prevent rainwater from entering from the joint part. A spacer 25 is provided on the other side of the base 20 .

The shape of the sealing material 24 is not particularly limited as long as it can prevent rainwater from entering. The sealing material 24 has elasticity, and exerts a sealing property by being inserted into the seam between the two exterior panels 1 and contracting.

As shown in FIG. 3 , in the first installation structure 100 , two outer wall panels 1 are joined using the first joining accessory 2 and attached to the building inner wall 5 with fasteners 3 and screws 4 . At this time, the plate-like projecting portion 23 of the first joining accessory 2 is inserted into the backing shell portion 10 . Furthermore, between the projecting portion 23 and the backing shell portion 10, and between the plate-like projecting portion 23 and the vertical end face without step processing, a sheet-like seal is provided at the tip of the projecting portion 23. A sealing surface is formed by interposing the material 24 by winding it.

With such an installation structure, the joint ends of the two outer wall panels 1 can be constructed so that the seam is inconspicuous in appearance. This improves the design of the outer wall of the building. In addition, since one joint end is a vertical end face without step processing, even if one end of the outer wall panel 1 is cut to fit the size of the actual building at the construction site, it can be joined as it is. It is not necessary for the builder to form the interlocking part on the spot, and the working efficiency of the construction is improved.

The two water stop parts 21 and 22 of the first joining accessory 2 have their tips abutted against the two outer wall panels, respectively, so as to prevent the rainwater that has entered from the joint part from penetrating deep into the back side of the outer wall panel 1. stop the water. In addition, the area surrounded by the base portion 20, the water stop portions 21 and 22, the projecting portion 23, and the vicinity of the joint end of the outer wall panel 1 communicates in the vertical direction, and functions as a rain gutter to drain water. Therefore, intrusion of rainwater can be prevented more effectively.

Furthermore, by adopting a structure in which the protrusion 23 is shaped like a plate and a sealing material is provided on both sides of the plate, the lateral width of the backing hole 10 can be reduced. , can be designed narrowly. As a result, the steps at the joint ends of the outer wall panels 1 can be formed shallow, so that the outer wall panels 1 can be used in combination with a sealing method that provides a better seal, as shown in a second embodiment described later. Since both construction methods can be used together with one type of panel, the burden of material management and construction work can be reduced, and human errors such as mixing up panels can be prevented.

FIG. 4 is a diagram schematically showing the first installation structure 100 of the outer wall of the building at the window side in the first embodiment.
Since the lateral width of the back-to-back lapel portion 10 of the outer wall panel 1 is narrow, the space for fixing the fasteners 3 becomes large even when the length of the outer wall panel 1 is shortened, so that the window side portion is narrow. The workability of the installation construction at the place is improved.

Specifically, for example, in a window side portion of a building, it is necessary to adjust the length dimension of the exterior wall panel 1 according to the arrangement of the windows 8 on the exterior wall surface of the building. When the distance from the edge of the adjacent outer wall panel 1 to the window 8 is short, the outer wall panel 1 cut short according to the distance is provided at the window side. From the viewpoint of mounting stability, it is preferable to apply the metal fitting method to the outer wall panel using the metal fittings 3, but when the outer wall panel 1 is cut short, the width for mounting the metal fittings 3 is insufficient, and the metal fittings are not fastened. Construction can be difficult. In particular, when the backing is lined, there is no room for the fastener 3 to be attached. On the other hand, if the backing bark portion 10 is formed narrowly, it becomes easier to fix the fastener 3, the workability of the mounting work is improved, and the metal fitting method can be performed more reliably, so that the mounting stability is improved. improves.

FIG. 5 is a perspective view showing an installation state of the outer wall panel 1 in the first installation structure 100. FIG.
As shown in FIG. 5, the sealing material is not exposed at the seam of the two outer wall panels 1 joined by the first installation structure 100, and the outer wall of the building has a high degree of design.

The first installation structure 100, which is the first embodiment of the present invention, has been described above. According to the first installation structure 100, in the sealingless construction method for installing the outer wall of the building, designability, workability of construction, and sufficient water stoppage can be ensured. can be designed narrowly.

As a result, the outer wall panel 1 for the sealingless construction method can also be used in the sealing construction method. Since both construction methods can be used together with one type of panel, the burden of material management and construction work can be reduced, and human errors such as mixing up panels can be prevented. In addition, it becomes easier to carry out the construction of the metal fitting method, and the workability and stability of installation in a narrow place such as a window side part are improved.

<Second embodiment>
Next, a second embodiment of the invention will be described. 2nd Embodiment is the 2nd installation structure 200 of the building outer wall shown in FIG.

The second installation structure 200 has the outer wall panel 1 and a hat-shaped shape, and the horizontal width of the hat-shaped protrusion 8 is formed to be wider than the plate thickness of the protrusion of the first joining accessory. The installation structure 200 of the building outer wall by the sealing construction method is configured to have the second joining accessory 6 and the wet sealing material 7 .

In the second installation structure 200, the two outer wall panels 1 are joined by the second joining accessory 6 at the joining portion between the backing shell portion 10 of one outer wall panel 1 and the longitudinal end surface of the other outer wall panel 1. , the protrusion 8 is partially inserted between the two second outer wall panels, and the wet sealing material 7 is enclosed in the joint surrounded on three sides by the two outer wall panels 1 and the protrusion 8; It is the installation structure 200 of the building outer wall by the sealing method.

The same outer wall panel 1 as in the first embodiment can be used together. In general, it is difficult to enclose the sealing material in the joint part of the external wall panel for the sealing-less construction method, where the seam is formed at the joint end, and it cannot be applied to the sealing method. difficult. Since the outer wall panel 1 of the present embodiment has a shallow step on the joint end surface due to the backing shell portion 10, the sealing material can be enclosed in the same way as in the case of an outer wall panel having no step on the joint end surface. Therefore, according to the outer wall panel 1, it is possible to install by the sealing method.

The second joining accessory 6 is a metal part that extends vertically along the vertical side of the outer wall panel 1, and has a hat-shaped horizontal cross section as shown in FIG. In the second installation structure 200, the second joining accessory 6 is arranged so that the two laterally adjacent outer wall panels 1 are separated from each other by the backing jagged portion 10 of one outer wall panel 1 and the other outer wall panel 1 without step processing. Used for joining at longitudinal edges.

For the sealing material 7, materials and construction methods used in ordinary sealing methods can be used. That is, a sealing material such as urethane or silicon can be used, and it may be formed by enclosing a paste-like sealing material in the joint of the two exterior panels 1 and curing it.

As shown in FIG. 6 , in the second installation structure 200 , the two outer wall panels 1 are joined using the first joining accessory 2 and attached to the building inner wall 5 with fasteners 3 and screws 4 . At this time, the convex portion 8 of the second joining accessory 6 is inserted between the two outer wall panels 1, and the sealing material 7 is enclosed in the area surrounded on three sides by the two outer wall panels 1 and the convex portion 8. be.

With such an installation structure, the joint ends of the two outer wall panels 1 are joined with high sealing performance, like the end faces without a step. This improves the water resistance of the outer wall of the building. In addition, since it is easy to use both the sealing-less construction method, which is highly designed, and the sealing method, which is excellent in sealing performance, depending on the part of the building, the efficiency of the installation work as a whole is improved.

The second installation structure 200, which is the second embodiment of the present invention, has been described above. According to the second installation structure 200, the exterior wall panel 1 used in the sealing-less construction method can be used in combination with the sealing method of the building exterior wall installation construction, and it is excellent as in the case of the exterior wall panel without a step on the joint end surface. It can exhibit sealing performance.

The outer wall panel 1 shown in the first embodiment and the second embodiment can be used in correspondence with both the sealingless construction method and the sealing construction method. For example, on walls that are conspicuous from the outside, a highly designed sealing-less construction method is used, and on places that are not conspicuous from the outside, such as windows and outdoor units of air conditioners, etc., a high-sealing construction method is used. Since it becomes easy to use both construction methods together, it is possible to easily realize a building outer wall with both good design and water resistance.

INDUSTRIAL APPLICABILITY The configuration of the present invention can be widely applied to installation structures for joining plate-like exterior wall panels of ceramic siding.
