DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a cross-sectional view after construction, and FIG. 2 shows a perspective view with a part omitted. An anchor bolt 7 is driven into an existing concrete wall 1, a channel-type support fitting 8 is attached to the anchor bolt 7 with a nut, and a channel-type attachment fitting 9 is attached to the support fitting 8 with a bolt. A stud frame 10 is bolted to the mounting bracket 9 to form a repair base 11. Thus, the structure for fixing the stud frame 10 to the existing wall 1 is generically referred to as the attachment means 2, but the structure can be variously modified.

The new wall 3 is constructed by connecting the heat insulating panels 15 ... Thermal insulation panel 1
In No. 5, a foamable resin material such as polyurethane or polyisocyanurate in which a polyol, an isocyanate, a catalyst, a foaming agent and the like are blended between two metal skins 12 and 13 is injected from a nozzle and foamed to form two metal shells. Metal skin 11,1
A foaming resin heat insulating material 14 is foam-filled between the two and cut into an appropriate length by a cutting device, and its width has a standardized predetermined dimension, for example, a working width of 910 mm or 600 mm.
It has become. The heat insulating panel 15 is fixed to the stud frame 10 by a fixture 19 such as a bolt. Then, the new wall 3 is attached to the front surface of the existing wall 1 via the attachment means 2 with different heights.

In the embodiment shown in FIG. 1A, the new wall 3 is mounted lower than the existing wall 1. The auxiliary cover 5 is made of a metal plate having a function of a headstock, and is bent in a substantially inverted U shape. A connection piece 5a is hung on the front surface of the existing wall 1 of the auxiliary cover 5. On the other hand, the base cover 4 having the draining function is connected to the connection receiving piece 4 from the rear edge thereof.
a is standing up. A fixing piece 16 is formed at the lower end of the base cover 4. Then, on the back of the existing wall 1, L
The metal-shaped fitting 17 is fixed with a bolt 18.
An L-shaped fixture 20 is attached to the upper end of the new wall 3 with a bolt 19.
Is fixed. The fixing piece 16 is brought into contact with the fixture 20 and fixed with the bolt 21 to cover the upper end of the new wall 3 with the base cover 4. With the auxiliary cover 5 placed on the existing wall 1, the fixing piece 22 is brought into contact with the fixture 17, and the bolt 23
Then, the back portion of the auxiliary cover 5 is fixed to the back surface of the existing wall 1. Then, the connection piece 5a and the connection receiving piece 4a are fixed to the existing wall 1 by the fixture 6. A caulking agent 24 is filled in the fixing portions of the fixing tool 6 and the bolts 23 and 16 so as to be watertight. In the embodiment of FIG. 3, the new wall 3 is constructed higher than the existing wall 1.

As described above, since the construction of the new wall 3 with the height different from that of the existing wall 1 can be performed, the degree of freedom of construction can be greatly increased, and the workability at various sites can be enhanced. In this case, it is divided into an auxiliary cover 5 that covers the top surface of the existing wall 1 and a base cover 4 that covers the top surface of the new wall 3, and compared to the conventional structure in which one piece is constructed, one piece Since the structure for raising and supporting the basic cover 4 that has become absent is omitted, the construction is remarkably facilitated and the construction is greatly improved. Further, the auxiliary cover 5 that covers the top of the existing wall 1 and the base cover 4 that covers the top of the new wall 3 have a connection piece 5a and a connection receiving piece 4 extending from them.
a is water-tightly fixedly connected to the existing wall 1 or the attachment means 2 by a fixing tool 6, and the auxiliary cover 5 and the base cover 4 are separated to improve the workability, and the fixing tool 6 for connecting the two is effective. Is used to increase the fixing strength of the auxiliary cover 5 and the base cover 4.

[0015]

According to the first aspect of the present invention, new walls having different heights are attached to the front surface of the existing wall through the attaching means, the upper end of the existing wall is covered with the auxiliary cover, and the upper end of the new wall is provided with the base cover. The connecting piece extending from the rear edge of the base cover to the auxiliary cover, the connecting piece extending from the rear edge of the auxiliary cover, and the connecting piece and the connecting piece fixed to the existing wall or the attachment means. Since it is water-tightly connected and fixed at, it is possible to perform construction with the height of the new wall different from that of the existing wall, greatly increasing the freedom of construction.
The workability at various sites can be improved, and
It is divided into an auxiliary cover that covers the top surface of the existing wall and a foundation cover that covers the top surface of the new wall. Compared to the conventional construction in which one piece is installed, the level of the base cover becomes one piece. There is an advantage in that the construction for supporting and supporting can be omitted, the construction can be remarkably facilitated, and the workability can be greatly improved. Moreover, the auxiliary cover that covers the top of the existing wall and the base cover that covers the top of the new wall are watertightly connected to the existing wall or the attachment means by the connecting piece and the connection receiving piece that are extended from these. There is an advantage that the auxiliary cover and the base cover can be fixedly connected to each other and the auxiliary cover and the base cover can be separated from each other to enhance the workability, and the fixing tool for connecting the both can be effectively used to increase the fixing strength of the auxiliary cover and the base cover. .

In the present invention, since the auxiliary cover is directly mounted on the upper end surface of the existing wall, the auxiliary cover can be temporarily placed and the auxiliary cover and the base cover can be easily connected. Also in this respect, there is an advantage that the workability can be enhanced. In Claim 3, the height of the new wall is lower than that of the existing wall, the connecting piece of the auxiliary cover hangs down, the connection receiving piece of the foundation cover stands up, and the connection is made between the upper end of the new wall and the upper end of the existing wall. Since the piece and the connection receiving piece are connected and fixed with a fixture, it is possible to construct a structure in which the new wall is lower than the existing wall, while utilizing the difference in height in this case and the auxiliary cover. There is an advantage that the workability of connecting to the base cover can be enhanced.

In the present invention, the height of the new wall is higher than that of the existing wall, the connecting piece of the auxiliary cover stands up, the connecting receiving piece of the foundation cover hangs down, and the space between the upper end of the new wall and the upper end of the existing wall is increased. In the above, since the connecting piece and the connecting receiving piece are connected and fixed by the fixing tool, the auxiliary cover and the base cover can be connected by utilizing the difference in height while heightening the new wall to enhance the appearance. It is also possible to improve workability in this respect.
