Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall structure in which a new outer wall panel is attached to an existing outer wall of a building.

[0002]

2. Description of the Related Art Conventionally, there is known an outer wall structure in which an outer wall material having a required exterior coating applied thereto is pasted on the surface of an existing outer wall to refresh the outer wall of the building. In this case, no large-scale construction is required, and the necessary surface painting is performed in advance at the factory. Although there is a great advantage that there is no need to do it, it was not just a range of renovating the outer wall and it did not improve the livability of the house.

[0003] In particular, a building that requires such exterior wall renovation is an old building that has been built for more than 10 years.
For this reason, there is a problem that functions such as heat insulation are far inferior to current buildings. Therefore, an outer wall structure has been proposed in which an outer wall material provided with a heat insulating material or the like is directly adhered to the surface of an existing outer wall to improve not only mere remodeling but also improve heat insulation performance and improve comfort.

[0004]

However, in the prior art, in any case, the flat outer wall material is simply adhered along the existing outer wall, and particularly in the corner portion of the existing outer wall, The outer wall members are adjacent to each other at right angles with the corner therebetween, and the corner-side end surfaces of these outer wall members are exposed. Therefore, in order to cover this exposed portion, consideration must be given to attaching the corner material across the surface of the outer wall material adjacent to the corner, which increases the man-hours and deteriorates the workability. Was.

Moreover, in this case, not only is the corner material conspicuous and the overall appearance is inconsistent, but also there is a step between the new outer wall material and the corner material, or the corner member is not attached. There was a problem that the head of the screw was exposed on the outer wall surface and the appearance was deteriorated.

[0006] In view of the above, the present invention provides an outer wall structure of a building that can improve not only mere renovation of the outer wall but also habitability, and can also improve workability and design. It is intended to provide.

[0007]

In order to solve the above-mentioned problems, according to the present invention, in an outer wall structure in which a new outer wall panel provided with a heat insulating material is directly adhered to the surface of an existing outer wall, A corner outer wall panel formed by pasting a heat insulating material having a predetermined thickness on the back surface of the L-shaped siding material is directly bonded to the surface of the corner portion.

The corner outer wall panel is formed by connecting two planar siding members to which a heat insulating material is attached so as to be orthogonal to each other by a connecting member attached so as to straddle between the back surfaces thereof.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an exploded perspective view of an outer wall structure according to an embodiment of the present invention. As shown in FIG. (2) The design of the outer wall surface is renewed by directly bonding (3) and (3).

[0010] The flat outer wall panel (2) is attached to a flat portion of the existing outer wall (1), and has a design pattern and a coating on the surface, for example, a thickness obtained by applying a coating to the surface of an embossed pattern. A siding material (4) of about 5 mm and a required thickness, for example, a thickness of 30 mm, on the back side of the siding material (4)
A material to which a certain amount of heat insulating material (5) is bonded in advance is used. As the heat insulating material (5), for example, a hard foamed polystyrene resin or the like is used.

Then, an adhesive (8) is applied so as to be applied to several places on the surface of the existing outer wall panel (7) constituting the existing outer wall (1), and the same applies to the four circumferences of the existing outer wall panel (7). An adhesive (8) is applied in a bead shape, and the flat outer wall panel (2) is adhered to the existing outer wall panel (7).

The corner outer wall panel (3) is an existing outer wall (1).
As shown in FIG. 2, two siding materials (4) and (4) with heat insulating materials (5) and (5) pre-adhered to the back surface, as shown in FIG. Those connected so as to be orthogonal to each other by an L-shaped connecting member (10) bonded so as to be straddled are used.

In the corner outer wall panel (3),
The end surface of the heat insulating material (5) of the other siding material (4) is brought into contact with the back surface of the heat insulating material (5) on the one siding material (4), thereby increasing the strength. In addition,
The siding material (4) and the heat insulating material (5) in the corner outer wall panel (3) are the same material and the same thickness as those used for the flat outer wall panel (2).

Then, the adhesive is applied so as to be provided at several places on the surface of the corner material (11) constituting the existing outer wall (1).
(8) is applied, and an adhesive (8) is similarly applied in a bead shape around the four corners of the corner material (11), and the corner outer wall panel (3) is adhered to the corner material (11) for construction. It is supposed to.

FIG. 3 is a cross-sectional view of a corner portion of the outer wall structure. In the figure, (15) and (15) are frame supports made of channel steels arranged so as to be orthogonal to each other, and the outer surfaces of the frame supports (15) and (15) have the above-mentioned existing outer wall. Panels (7) and (7) are attached respectively. These existing exterior panels (7) and (7) have a U-shaped iron frame (16),
Siding material (17) attached to the front side of the iron frame (16)
And a back plate (18) also attached to the back side, and a heat insulating material filled between the siding material (17) and the back plate (18).
(19).

Reference numeral (20) denotes a corner support made of an L-shaped steel member disposed at a corner between the frame supports (15) and (15). Corner material (11) is attached. This corner material (11)
It has outer surfaces (21) (21) orthogonal to each other, and these outer surfaces (21) (21) are flush with the siding materials (17) (17) of the adjacent existing outer wall panels (7) (7). It has become.

The joints between the corner members (11) and (11) and the existing outer wall panels (7) and (7) are provided with the outer surface (21) in advance.
A joint sheet (22) is stuck between (21) and the siding material (17) (17), and an adhesive (8) is applied as described above to apply a flat outer wall panel (2) and a corner outer wall. panel
(3) is adhered. And a new exterior wall panel (2)
After filling the joint portion between (3) and the joint filler (23), a sealing material (24) made of synthetic resin is fitted from the outside.

[0018]

As is apparent from the above description, according to the present invention, a corner outer wall panel formed by attaching a heat insulating material to the back surface of an L-shaped siding material is directly bonded to the surface of the corner portion of the existing outer wall. This eliminates the need for special work such as attaching a corner material after pasting the outer wall panel as in the past, and improves the workability by easily performing refresh work on the corners of the existing outer wall. be able to. In addition, it is possible to solve the problem that a step is formed at the corner portion of the existing outer wall or the head of the screw is exposed, and it is possible to improve the design as a uniform appearance as a whole. Further, it is possible to improve not only the outer wall renovation but also the heat insulation performance to improve the livability.

The corner outer wall panel has an extremely simple structure in which two planar siding members to which a heat insulating material is attached are connected by a connecting member, thereby increasing the productivity of the corner outer wall panel. And the construction cost can be reduced.
