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 outer wall in which an opening for an entrance is formed in an existing outer wall.

[0002]

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

[0003]

However, in the above-mentioned conventional example, since the entire outer wall panel is replaced, the remodeling work is troublesome, and furthermore, since the outer wall panel having a new opening is replaced, the cost is reduced. Was also expensive. SUMMARY OF THE INVENTION 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 for an entrance on an existing outer wall, and form an opening for an entrance. It is an object of the present invention to provide a method for remodeling an outer wall which can prevent a decrease in strength of a portion which has been made.

The anchor 8 is buried in the existing foundation 3 and the reinforcing bracket 5 is fixed to the anchor 8 so that both sides of the portion where the opening 2 for the entrance is provided are firmly connected to the foundation 5 for reinforcement. It is supposed to.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the accompanying drawings. The opening 2 for the entrance is formed in the existing outer wall panel 1 incorporated in the building by remodeling. In the embodiment, the opening 2 for the entrance is formed in the outer wall panel 1 in which the existing window 9 is formed. The example formed is shown. Here, the formation of the opening 2 for the entrance in the existing outer wall panel 1 is performed as follows.

[0007] First, as shown in FIG.
As shown in FIG. 2 (b), the existing outer wall panel 1 is cut along both sides of the existing window 9 to form an opening 2 for an entrance. In this case, the metal lower frame 10 of the existing outer wall panel 1 is cut at a portion corresponding to the opening 2 for the entrance. In addition, the existing outer wall panel 1
The metal vertical frame 13 inside is exposed on both sides of the access opening 2.

Next, as shown in FIG. 2 (c), a recess 4 is formed by shaving off the upper part of the existing foundation 3 located below both sides of the opening 2 for the entrance. The recess 4 is formed from below the portion where the lower frame 10 of the outer wall panel 1 is cut to below the portion where the lower frame 10 is not cut. Then, the reinforcing metal fitting 5 is put on the recess 4 thus formed. In this case, a reinforcing metal fitting 5 as shown in FIG.
Then, the inverted U-shaped portion 11 at the lower portion of the reinforcing metal fitting 5 is fitted to the bottom of the concave portion 4, and in this state, the reinforcing metal fitting 5 is slid to be positioned below the uncut end of the 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 drilled in the lower frame 10, a connection bolt 6 is passed through the hole, and a lower portion of the connection bolt 6 is passed through a hole 16 provided in an upper horizontal piece 15 of a receiving stand 14 on the upper part of the reinforcing metal fitting 5. The connection bolt 6 is welded to the frame 13, and the nut 17 is screwed into the connection bolt 6 to connect the existing outer wall panel 1 and the reinforcing bracket 5.

Next, the anchor 8 is buried in the existing foundation 3 and the reinforcing member 5 is fixed to the anchor 8.
As the anchor 8 used here, for example, the following can be used. That is, the existing foundation 3
A hole 18 is formed in the glass tube. Then, the base material is an epoxy acrylate resin which has excellent alkali resistance, has a strong fixing force, and does not change with time, and a hardening agent and a magnesia clinker ceramic aggregate are mixed into a glass tube at a fixed mixing ratio. 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.

After the anchor 8 is buried in the foundation 3 and the reinforcing metal member 5 is fixed to the foundation 3 by the anchor 8, the nut 17 may be tightened again.
The reinforcing fitting 5 is provided with a mortar filling hole 20 for filling the mortar 20 from the mortar filling hole 20. The mortar is also used for backfilling and repairing the recess 4.

An opening frame (not shown) is attached to the opening 2 for the entrance formed on the existing outer wall panel 1 in this manner. Thus, even if the opening 2 for the entrance 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 foundation 3 via the reinforcing metal 5 by the reinforcing metal 5. In other words, the structural strength can be maintained.

[0013]

According to the present invention, as described above, the existing
Both sides a portion of the existing external wall panel having a window of existing windows
Cut along the edge to form an opening for the doorway.
Enter and exit the vertical metal frame inside the existing exterior panel
It is exposed on both sides of the opening for the opening, and the existing foundation located below both sides of the opening for the entrance is shaved off to form a recess, a reinforcing bracket is fitted in this recess, and a connecting bolt is connected to the reinforcing bracket. Attach and attach the connecting bolts to the frame of the existing outer wall panel, embed the anchor in the existing foundation, and fix the reinforcing bracket to this anchor .
Cut out exterior wall panels to form openings for doorways
Cut along both sides of the existing window
Can be easily and accurately removed.
Just cut along both sides of the window
Existing metal vertical frame opening for easy entrance
Can be exposed on both sides of the
Existing members that will be on both sides of the opening for the exit
The metal vertical frame of the outer wall panel can be firmly connected to the foundation via the reinforcing metal to reinforce, and as a result, the opening for the entrance is formed in the existing outer wall panel by remodeling. Without removing and replacing the outer wall panel,
It can be modified easily and with strength while leaving the existing outer wall panel.
