Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for remodeling an outer wall of a building, and more particularly to a structure for remodeling an aging outer wall (building side wall and roof surface) with a plurality of exterior panels.

[0002]

[Background Art] When repairing the exterior wall of a dilapidated building, in recent years, instead of removing the existing exterior wall or overcoating the existing exterior wall with mortar, multiple exterior panels made of aluminum or the like have been used in recent years. The method of attaching to is adopted.

By the way, when an exterior panel is used,
It is necessary to surely perform joint treatment between panels, especially waterproof treatment. For this reason, conventionally, as shown in FIG. 9, one edge of the exterior panel 90 adjacently arranged is extended as a trough portion 91 to the lower side of the other panel 90, and provisionally provided between the panels 90. Even if the sealing material 92 provided is cut and rainwater enters, the gutter 91 receives the rainwater and drains it outside the building.

[0004]

However, in such a structure, the exterior panels 90 are arranged side by side in the inclination direction of the exterior panel 90, that is, in the vertical direction for the outer peripheral wall and in the water gradient direction for the roof ( In the case of horizontal joints), since the gutter portion 91 is divided, it is necessary to connect the gutter portion 91 with a joint member or to use a long exterior panel 90 so that the gutter portion 91 is not divided. . Therefore, there are problems that the installation work of the exterior panel 90 becomes complicated and the workability is deteriorated, and the size of the exterior panel 90 limits the building that can be remodeled.

When the panels 90 are arranged in a zigzag pattern in consideration of replacement of the panel 90 after construction, the panel 90
There is also a problem in that the gutter portion 91 cannot be provided and the sealing material 92 alone must be used for waterproofing since the end portion of the is divided into zigzags. Therefore, the seal must be frequently repaired as the sealing material 92 deteriorates, and the repair work is complicated and the cost is high.

An object of the present invention is to provide an exterior wall remodeling structure for a building in which the exterior panel can be easily installed and the rain finish of the joint portion of the exterior panel can be improved.

[0007]

An outer wall remodeling structure for a building according to the present invention is an outer wall remodeling structure for a building, wherein an outer panel for refurbishment is attached to a surface side of an existing outer wall of the building to cover the existing outer wall. A plurality of gutter-shaped vertical members laterally separated by a predetermined distance on the surface of the existing outer wall were attached over the entire length of the outer wall in the vertical direction, and were vertically separated by a predetermined distance between the gutter-shaped vertical members. A plurality of base materials for panel mounting are installed by straddling, the upper and lower edges of the exterior panel are mounted on the base material for panel mounting, and vertical joints between the left and right end edges of the exterior panel are made into the gutter-shaped vertical materials. On the other hand, it is characterized in that it is arranged at a position in the direction orthogonal to the outer wall surface.

Further, in the outer wall remodeling structure of the present invention, a plurality of gutter-shaped vertical members arranged laterally on the surface of the existing outer wall at predetermined intervals are attached over the entire length of the outer wall in the vertical direction,
A plurality of piece-shaped panel-mounting base materials are attached along the gutter-shaped vertical members in each gutter-shaped vertical member, and the left and right edges of the exterior panel are positioned relative to the gutter-shaped vertical members in the direction perpendicular to the outer wall surface. And may be fixed to the panel mounting base material.

In the present invention, the outer wall of the building includes not only the outer wall on the side of the building but also the roof of the building. Therefore, the vertical direction in which the gutter-shaped vertical members are installed means the vertical direction on the side surface of the building and the direction along the water gradient on the roof surface.

[0010]

In the present invention as described above, the gutter-shaped vertical members are attached to the existing outer wall of the building over the entire length in the vertical direction of the outer wall,

Also, the exterior panels 4 and 5 are attached to the outer walls 2 and 3 for remodeling, and most of them can be attached by bolts, so that so-called dry construction can be performed, The renovation work can be simplified and the construction period can be shortened.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope of achieving the object of the present invention are included in the present invention. For example, in the above-described embodiment, a so-called horizontal type exterior panel 4 for fixing the upper and lower edges 4A of the panel with screws is attached to the inclined outer wall 2 of the building 1, and the left and right edges 5B and 5C of the panel are attached to the vertical outer wall 3. The so-called vertical type exterior panel 5 which is screwed is attached, but both types of exterior panels 4 and 5 may be attached to the outer walls 2 and 3 opposite to each other, or either one of the exterior panels 4 and 5. Both outer walls 2 and 3 may be refurbished using only 5, and the mounting type of the exterior panel may be appropriately set according to the outer wall to be installed.

The present invention also relates to the outer wall 2 on the side surface of the building 1.
Not only 3 but also applicable to the renovation of the roof surface of the building 1. Furthermore, the exterior panel, like the above-mentioned embodiment,
It is not limited to those arranged in the vertical direction, but may be arranged in a staggered manner as shown in FIG. In this case, the gutter-shaped vertical members 81 are arranged on the panels 8 so that the left and right edges 80B and 80C of the outer panels 80 are arranged on the gutter-shaped vertical members 81.
It suffices to install a plurality of pieces at intervals of half the width dimension of zero. Therefore, when the trough portion 91 is provided at the end of the conventional exterior panel 90, the exterior panels 80 can be arranged in a zigzag pattern in which the trough portions are cut and cannot be installed. The replacement work of 80 can be easily performed.
