Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for remodeling an existing outer wall by forming an opening for entrance and exit.

[0002]

2. Description of the Related Art Conventionally, in order to form an opening for a doorway in an existing outer wall, the entire outer wall panel of the corresponding portion is removed,
This was done by installing a new outer wall panel with an opening.

[0003]

However, in the above-mentioned conventional example, since the outer wall panel is replaced, the remodeling work is troublesome, and since the outer wall panel having a new opening is replaced, the cost is reduced. There was a problem that it cost too much. The present invention has been made in view of the above-mentioned problems of the conventional example, and an object thereof is to easily form an opening / closing opening for an existing outer wall and to form an opening / closing opening for entrance / exit. Another object of the present invention is to provide a method of remodeling the outer wall that can prevent the strength of the damaged portion from decreasing.

[0004]

According to a method of remodeling an outer wall of the present invention, a part of an existing outer wall panel 1 is cut out to form an opening 2 for an entrance and exit, and the opening 2 for entrance and exit is positioned below both sides of the opening 2. The existing foundation 3 is scraped off to form the concave portion 4, and the reinforcing metal fitting 5 is fitted into the concave portion 4 to form the reinforcing metal fitting 5.
The connecting bolt 6 is attached to the frame, the connecting bolt 6 is welded to the frame 7 of the existing outer wall panel 1, the anchor 8 is embedded in the existing foundation 3, and the reinforcing metal fitting 5 is fixed to the anchor 8. By adopting such a method, the problems of the above-mentioned conventional example are solved and the object of the present invention is achieved.

[0005]

When forming the opening 2 for the entrance / exit in the existing outer wall panel 1, the existing outer wall panel 1 is used.
The opening 2 for the entrance / exit is formed by cutting off a part of the base 2, and the existing base 3 located on both lower sides of the opening 2 for the entrance / exit is scraped off to form the recess 4 and the recess 4 is reinforced. Fit the metal fitting 5 and connect the reinforcing bolt 5 to the connecting bolt 6
By attaching the connection bolt 6 to the frame 7 of the existing outer wall panel 1, embedding the anchor 8 in the existing foundation 3 and fixing the reinforcing metal fitting 5 to the anchor 8, the opening 2 for the doorway is formed. Both sides of the provided portion are firmly connected to the foundation 5 for reinforcement.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the accompanying drawings. The opening 2 for entrance and exit is formed by modifying the existing outer wall panel 1 incorporated in the building, but in the embodiment, the opening 2 for entrance and exit is formed on the outer wall panel 1 having the existing window 9. The formed example is shown. Here, the opening 2 for the entrance / exit is formed in the existing outer wall panel 1 as follows.

First, as shown in FIG. 2A, an existing window 9 is installed.
As shown in FIG. 2B, the existing outer wall panel 1 having the above is cut along both sides of the existing window 9 to form the opening 2 for the entrance and exit. In this case, the metal lower frame 10 of the existing outer wall panel 1 is to be cut at the portion corresponding to the opening 2 for the entrance / exit. In addition, the existing outer wall panel 1
The metal vertical frame 13 inside is exposed on both sides of the entrance / exit opening 2.

Next, as shown in FIG. 2 (c), the upper part of the existing base 3 located below both sides of the opening 2 for entrance and exit is scraped off to form a recess 4. The concave portion 4 is formed from below the cut portion of the lower fluff 10 of the outer wall panel 1 to below the uncut portion of the lower frame 10. Then, the reinforcing metal fitting 5 is put on the recessed portion 4 thus formed. In this case, the reinforcing metal fitting 5 as shown in FIG. 3 is inserted into the recess 4 from below the cut portion of the lower frame 10.
Then, the inverted U-shaped portion 11 of the lower portion of the reinforcing metal fitting 5 is fitted on the bottom portion of the concave portion 4, and in this state, the reinforcing metal fitting 5 is slid to be positioned below the end portion of the uncut lower frame 10.

Next, as shown in FIG. 1, the connecting bolt 6 is attached to the reinforcing metal member 5, and the connecting bolt 6 is welded to the vertical frame 13 which is the frame 7 of the existing outer wall panel 1. In this case, a hole is bored in the lower frame 10, the connecting bolt 6 is passed through this hole, and the lower portion of the connecting bolt 6 is passed through the hole 16 provided in the upper horizontal piece 15 of the pedestal 14 at the upper portion of the reinforcing metal fitting 5, and The connecting bolt 6 is welded to the frame 13 and the nut 17 is screwed into the connecting bolt 6 to connect the existing outer wall panel 1 and the reinforcing metal fitting 5.

Next, the anchor 8 is embedded in the existing foundation 3 and the reinforcing metal member 5 is fixed to the anchor 8.
As the anchor 8 used here, for example, the following can be used. That is, existing foundation 3
Next, make a hole 18 in the glass tube, and then use epoxy acrylate resin, which has excellent alkali resistance, strong adhesion, and does not change over time, as the main material, and hardener and magnesia clinker ceramic aggregate in a fixed mixing ratio into a glass tube. The housed and sealed resin capsule is inserted into the hole 18, and then the anchor bolt 19 is embedded in the hole 18 to break the resin capsule,
The anchor bolt 19 is fixed by curing the resin.

It is also possible to embed the anchor 8 in the base 3 in this way, fix the reinforcing metal fitting 5 to the base 3 by the anchor 8, and then tighten the nut 17 again.
The reinforcing metal fitting 5 is provided with a mortar filling hole 20 for filling the mortar 20 through the mortar filling hole 20, and the recess 4 is also backfilled or repaired with mortar.

An opening frame (not shown) is attached to the entrance / exit opening 2 formed in the existing outer wall panel 1 in this manner. Even if the opening 2 for the entrance and exit is formed in the outer wall panel 1 as described above, the lower ends on both sides of the opening 2 are firmly supported by the reinforcing metal fitting 5 on the foundation 3 through the reinforcing metal fitting 5. As a result, the structural strength can be maintained.

[0013]

As described above, according to the present invention, a part of the existing outer wall panel is cut out to form an opening for an entrance and exit, and the existing opening is located below both sides of the opening for entrance. The foundation is scraped off to form a recess, a reinforcing metal fitting is fitted into this recess, the connecting bolt is attached to the reinforcing metal fitting, the connecting bolt is welded to the frame of the existing outer wall panel, and the anchor is embedded in the existing foundation to create the anchor. Since the reinforcing metal fittings are fixed to, it is possible to firmly connect both sides of the part where the opening for the entrance and exit is provided to the foundation for reinforcement,
As a result, when forming the opening for entrance and exit in the existing outer wall panel by modifying, it is possible to easily modify the existing outer wall panel while keeping the existing outer wall panel without removing and replacing the outer wall panel. is there.
