Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a construction method for repairing an exterior wall of an architecture or structure, such as a prefabricated exterior wall formed of a mortar wall or a tile wall. (Prior Art) Japanese Patent Publication No. 17869/1983 is known as this type of construction method. In other words, the base frame is vertically extended onto the exterior wall covered with dry-type exterior wall material and extends to the draining edge of the existing wall, and the liner material is fixed horizontally to the foundation either directly or through an attached foundation. A starter material is fixed onto this liner material, the first stage of new exterior wall material is installed, and the exterior wall is repaired by successively roofing. (Problems to be Solved by the Invention) The construction method described above lacks stability because the substratum is not fixed to the foundation, and the starting material protrudes outward from the foundation and the substratum protrudes from the existing exterior wall. There were disadvantages such as large discrepancies in dimensions, making construction difficult, and deteriorating the aesthetic appearance. Furthermore, since the liner material is exposed to the outside air and is exposed to wind and rain, there is a drawback that the liner material and the starter material corrode.
Furthermore, the above construction method requires a base frame and a liner material, which is disadvantageous in that it has poor workability and increases costs. (Means for Solving the Problems) In order to solve these drawbacks, the present invention fixes the base drainer to the lower edge of the existing external wall, abuts the lower end of the vertical rim on the attachment part, and It is fixed vertically at a position corresponding to the outer wall frame, and fixed with a short spacer interposed between the lower ends of this vertical rim at the same height as the vertical rim, and then the starter is horizontally attached to the lower end of the vertical rim. The first stage of external wall material is formed by installing dry external wall material horizontally on this, and then attaching the second stage of external wall material to the top of the first stage of external wall material. A new exterior wall is constructed by repeating the process of engaging the lower ends in sequence until the desired height is reached. (Function) The foundation drainer installed at the lower end of the existing exterior wall, the so-called foundation part, covers the lower end of the existing exterior wall and functions as a decorative material for the end, and the vertical trim extends from the top of the foundation drainer to the required height. The spacer is fixed vertically and functions as a mounting body for the starter and the new exterior wall material, and furthermore, the spacer closes the opening formed between the lower ends of the vertical rim. (Example) Hereinafter, an example of the outer wall repair method according to the present invention will be described using the drawings. FIG. 1 is a perspective view showing an example of the repair method according to the present invention, in which numeral 1 indicates a frame of an existing wall, such as a stud, and 2 an existing mortar wall (hereinafter simply referred to as wall) structure. To explain further, the wall 2 is made of wood, for example, on the outer surface of the frame 1.
It consists of a mortar wall structure constructed in the following order: waterproof sheet, lath sheet, and mortar wall material. 3 is a foundation, 4 is a base, and 5 is a foundation drainer, which is installed horizontally at the lower end of wall 2 to form the base of a new exterior wall to be described later. To explain further, the base drainer 5 is formed as shown in FIGS. 2a to 2e to enhance the waterproofness, corrosion resistance, and aesthetics of the lower end of the new outer wall. Its shape consists of a vertical mounting part 6, a horizontal or inclined drainage part 7, and a cover part 8 having a vertical decorative surface. Reference numeral 9 denotes a vertical rim, which is perpendicular to the position corresponding to the frame 1 of the wall 2, and whose lower end is a mounting part 6 for the base drainer 5.
It is located on the top of the wall 2 and is fixed to the frame 1 via nails 17 in contact with the surface of the wall 2. A spacer 10 is arranged and fixed horizontally between the lower ends of the vertical furring 9 to close an opening formed by the vertical furring 9, the wall 2, and an outer wall material to be described later. Reference numeral 11 is a starter that is fixed horizontally on the mounting part 6 of the foundation drainer 5, and is mainly used to lock and fit the outer wall material 16, as well as to prevent wind and rain from entering the lower end of the new wall. be. Its shape is shown in Figure 3 a~
It consists of a long body with a cross section as shown in f. In other words, figures a to c are hook type, and figures d to f are hook type.
The figure shows one suitable for installing a drop-in type exterior wall material 16. Specifically, the nailing part 12 is formed by roll forming, pressing, etc. a thin metal plate.
It is composed of a bottom part 13 and an engaging part 14. Reference numeral 15 denotes a new exterior wall, which is constructed by sequentially roofing dry exterior wall materials 16 in the horizontal direction.The exterior wall materials 16 are long composite boards, not shown, with cross sections as shown in Figures 4 a to j. It is made of one type of single plate or the like. The connecting portion structure of the outer wall material 16 is either a hook type or a drop type. Numeral 17 is used to fix the foundation drainer 5 , starter 11, spacer 10, and exterior wall material 16 to the frame 1 with nails. A waterproof sheet 18 is used as needed between the wall 2 and the outer wall material 16, and mainly functions as a dew condensation prevention material, a rust prevention material, a waterproof material, and a cushion material for the wall 2.
Specific examples thereof include asphalt felt and terfelt. Next, an embodiment of the exterior wall repair method according to the present invention will be described in detail. Now, in the existing wall structure as shown in FIG.
As shown in the figure, the base drainer 5 is fixed in the horizontal direction via nails 17. Next, the lower end of the vertical rim 9 is brought into contact with the mounting part 6 of the base drainer 5 and fixed vertically at a position corresponding to the frame 1 . Thereafter, the spacer 10 is fixed at the lower end between the vertical furring edges 9 and on the attachment part 6 of the base drainer 5 to close the opening formed at the lower end of the vertical furring edge 9. Next, a starter 11 as shown in FIG. 3b is fixed via nails 17. After that, the outer wall material 16 as shown in FIG.
The upper end is fixed to the frame 1 from above the wall 2 via the nails 17. Therefore, new exterior wall 1
5 can be formed by sequentially and repeatedly performing the steps described above. (Effects of the Invention) As described above, according to the exterior wall repair method according to the present invention, there is no need to dismantle the existing exterior wall, so the number of construction steps can be omitted, and the construction period can be significantly shortened. It has the characteristic that it will not cause any hindrance to residence during construction. In addition, in the present invention, a foundation drainer is provided at the lower end of the mortar wall, the vertical rim is fixed vertically on the foundation runner and at a position corresponding to the skeleton of the existing wall, and a starter is attached to this vertical rim image. , because it was created using a new exterior wall material, it has the characteristic of being constructed with a uniform appearance. Furthermore, it is easy and simple to install by simply installing the foundation drainer, vertical rim, short spacer, starter, and exterior wall material on the existing wall.
It is easy to install, and since the opening at the lower end of the new wall is also closed, there is no condensation and there is little deterioration of the back surface of the exterior wall material or the surface of the existing wall. Further, when an outer wall is formed using the outer wall repair method according to the present invention, it has a double wall structure with an existing wall, and has the characteristic of becoming a wall structure that is rich in heat insulation, soundproofing, and fireproofing properties.
