Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building and a building
The present invention relates to a repair rim used for repairing an existing outer wall made of C member (lightweight cellular concrete) with a new outer wall.

[0002]

2. Description of the Related Art Conventionally, as a rim for repairing an existing outer wall using an ALC member, it is general to simply use square wood or various lightweight steel materials, which are rims for new construction, as they are. there were.

[0003]

A fixing device such as a nail or a screw screw is attached to the outer rim of the body at right angles to the outer rim. However, the ALC outer wall that has become old is cracked, partially dropped, and deteriorated in strength due to frost damage and changes over time due to its properties. And there is a danger of falling off or peeling off due to an external impact such as a typhoon or an earthquake.

[0004]

According to the present invention, in order to eliminate such drawbacks, the fixing portion of the repairing rim is formed to be inclined so that the fixing tool is driven into the existing outer wall with the inclination. As a result, the mounting strength of the body edge is improved, the body edge is prevented from falling off, and the body edge is formed from the two members of the locking body and the cover body, and the body edge is fixed by elastic fitting to be integrated. The present invention proposes a refurbishment rim in which, when the cover body is concealed by the cover body and a new outer wall material is attached to the cover body, the fixation part to which the body rim is attached does not become in the way.

An embodiment of the repairing rim A according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view of the repair rim A. The repair rim A is composed of two members, a locking body B and a cover C.

The locking member B has a cross-sectional shape as shown in FIG. 2 (a), and is formed of an elongated body as shown in FIG. 2 (b), and is formed by molding various lightweight steel materials into a predetermined shape. is there.
The cross-sectional shape is composed of a horizontal installation piece 1, a fixing portion 2 which is formed by projecting a part of the installation piece 1 by being inclined, and an engagement piece 3 in which both ends of the installation piece 1 are bent upward.

The installation piece 1 is a part to be installed on an existing outer wall, and the fixing part 2 is a part to which a fixing tool such as a nail or a screw is obliquely hit to attach the locking body B to the existing outer wall. More specifically, the shape of the fixing portion 2 will be described in more detail. A projecting portion 4 which is formed by projecting the middle of the installation piece 1 in a substantially convex shape, and a fixing surface in which the top surface of the projecting portion 4 is recessed downward into a substantially triangular shape. It is formed from a recessed portion 7 composed of pieces 5 and 6.

Further, as shown in FIG. 2 (b), the fixing pieces 5, 6 are provided with pilot holes 7 serving as guides for the fixing tool α to be described later.
May be formed in advance.

The engaging piece 3 is a portion for integrally attaching the cover C to be described later by elasticity. For example, the engaging piece 3 is bent in a V-shape as shown in FIG. This is to prevent it.

The cover C has a cross section as shown in FIG. 3A, for example, and is formed of an elongated body as shown in FIG. 3B.
It is formed by molding various lightweight steel materials into a predetermined shape. The cross-sectional shape includes a horizontal decorative surface 8 and a decorative surface 8.
And a fitting piece 9 having both ends protruding downward.

The decorative surface 8 is a portion serving as a lower ground for attaching a new outer wall material. In the drawing, a plurality of ribs 10 are formed. The rib 10 also has functions of reinforcing the strength of the cover body C and preventing slippage of the outer wall material when attaching a new outer wall material.

The right and left fitting pieces 9 are provided with the above-mentioned locking body B.
Are elastically integrated with each other, for example, as shown in the figure, are bent in the shape of a letter, thereby strengthening the elastic fitting force and strengthening the connection green with the locking body B.

Next, an example of the construction of the repair rim A according to the present invention will be described. Figure 4 shows the AL using the repair rim A
This shows a wall surface obtained by modifying an existing outer wall material 11 made of C with a new outer wall material 12 such as siding.

FIG. 5 corresponds to the cross-sectional view of FIG. 4, in which a locking member B is installed on an existing outer wall material 11 and a fixing tool α made of nails or screws is fixed to the fixing pieces 5 and 6 by an angle. It is inclined at θ and is driven into the existing outer wall material 11 to fix the locking body B.

At this time, the angle θ is about 45 degrees as a guide, and has the highest pull-out strength and a high fixing force. Next, the cover body C is elastically fitted to and attached to the locking body B, a new outer wall material 12 is provided with the decorative surface 8 of the cover body C as a mounting base surface, and the repair body edge is fixed by the fixing tool α. A new exterior wall material 12 is fixed to A and the wall surface is repaired.

In FIG. 4, reference numeral 13 denotes a waterproof sheet provided as needed. Further, depending on the type of the new outer wall material 12 to be attached, the repairing rim A can be attached in the vertical direction as shown in the drawing, or can be attached in the horizontal direction or in a rectangular frame.

What has been described above is a typical embodiment of the repairing rim A according to the present invention. The repairing rim A as shown in FIGS. That is, FIGS.
Shows other examples of the deformed locking body B. In particular, in FIGS. 7B and 7C, reference numeral 13 denotes a packing body for preventing vibration after mounting and improving the adhesion of fitting.

FIG. 8 shows another example of the cover C. In FIG. 8C, particularly, 13 is a packing, which is useful for preventing vibration and resonance after mounting and improving strength.

FIGS. 9A and 9B show an example in which the method of fitting the locking body B and the cover body C is modified.
Of course, it is possible to form a repair rim by combining these.

[0020]

As described above, according to the repairing rim according to the present invention, the fixing portion of the repairing rim is formed to be inclined, so that the fastener is driven into the existing outer wall so as to be inclined. Since it is performed, the mounting strength of the body edge is improved, and the falling off can be prevented. The edge of the body is a locking body and a cover body.
Formed from members and integrated by elastic fitting, the cover body conceals the fixture that fixes the body edge, and when attaching a new outer wall material to the cover body, the fixture that attaches the body edge Does not get in the way. There are effects and features such as.
