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 exterior 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, there was a drawback that there was no guide at all when fixing the underlying bone, making it difficult to install and having poor workability. (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, and forms a notch on the attachment part to serve as a guide for the vertical rim. Install a mounting body horizontally, fit the cut-out part of the lower end of the vertical rim into the notch of this mount, and fix it on the existing external wall. Next, attach the starter horizontally to the lower end of the vertical rim. A dry exterior wall material is placed horizontally on this and attached to form the first stage exterior wall.
Next, a new exterior wall is constructed by sequentially repeating the process of engaging the lower end of the second-tier exterior wall material with the upper end of the first-tier exterior wall material until the required 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. It is fixed vertically and functions as a mounting body for the starter and new exterior wall material.Furthermore, the mounting body closes the opening formed between the lower end of the vertical rim and guides the fixing position of the vertical rim. belongs to. (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. 1 is a frame of an existing external wall, for example, studs, and 2 is an existing mortar wall (hereinafter referred to as an end wall) structure. To explain further, the wall 2 is made of a mortar wall structure in which, for example, lath, a waterproof sheet, a lath sheet, and a mortar wall material are applied in this order to the outer surface of the frame 1 .
3 is the foundation, 4 is the foundation, and 5 is the foundation drainer, which is placed horizontally at the bottom of wall 2 to form the base of the new wall to be described later. To explain further, the base drainer 5 is formed as shown in FIG. 2 a to e,
This will strengthen the waterproofness, corrosion resistance, and aesthetics of the lower end of the new exterior 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 mounting body, which has a notch 9a formed in the wall 2 at a position corresponding to the frame 1 as shown in FIG. It is for guiding and fitting the edge 10 . Reference numeral 10 denotes a vertical rim, which is perpendicular to the position corresponding to the frame 1 of the wall 2, and whose lower end is connected to the mounting body 9.
It fits into the notch 9a of the wall 2, and its back surface abuts the surface of the wall 2 and is fixed to the frame 1 via nails 17. In addition, as shown in FIG. 4, the vertical furring 10 has a notch 10a formed at its lower end, which fits into the notch 9a of the mounting body 9 , and whose total thickness is equal to the vertical furring. The thickness is the same as that of No. 10 . Reference numeral 11 denotes a starter, which is fixed horizontally to the lower end of the vertical rim 10 , and is mainly used to lock and fit the new exterior wall material 16, as well as to prevent wind and rain from entering the lower end of the new wall. It is for the purpose of Its shape consists of an elongated body with a cross section as shown in FIGS. 5a to 5f. That is, figures a to c are suitable for attaching a hanging type exterior wall material 16, and figures d to f are a drop-in type. Specifically, the nail driving part 12 and the bottom part 1 are formed by roll forming, pressing, etc. a thin metal plate.
3 and an engaging portion 14. 15
6 is a new exterior wall, which is constructed by sequentially roofing dry exterior wall materials 16 in the horizontal direction. The exterior wall materials 16 have cross sections as shown in FIGS. It consists of one type of plate or the like. The connecting portion structure of the outer wall material 16 is either a hook type or a drop type. 17: Drain the base with nails 5 , Starter 1
1. Attachment body 9 , vertical rim 10 , outer wall material 16 to frame 1
It is used for fixing. 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 structure of the wall 2 as shown in FIG. 1, a foundation drainer 5 as shown in FIG. 2a is horizontally fixed to the lower end of the wall 2 via nails 17. Next, the mounting body 9 is fixed horizontally onto the mounting portion 6 of the base drainer 5 so that the notch portions 9a are located in correspondence with the spacing of the frame 1 . Next, the notch 10a at the lower end of the vertical furring 10 is fitted into the notch 9a and fixed vertically at a position corresponding to the frame 1 . Next, a starter 11 as shown in FIG. 5b is fixed via nails 17. After that, the outer wall material 16 as shown in FIG . Fix it. Therefore, in order to form the new outer wall 15 , it is sufficient to sequentially and repeatedly perform the above-described steps. (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 base drainer is provided at the lower end of the mortar wall, a mounting body is fixed on the base drainer, and the vertical rim is fixed vertically using the mounting body as a guide and on top of the prefabricated outer wall. Since the starter and new exterior wall materials were constructed on this vertical rim, the construction has a uniform appearance. Furthermore, all you need to do is install the foundation drain, vertical rim, starter, and exterior wall materials on the existing exterior wall.
It is simple and easy, and since the opening at the bottom of the new wall is also closed, there is no condensation, and the back side of the exterior wall material
It also has the characteristic that there is little deterioration of the existing wall surface. 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 the existing outer wall, and has a feature that the wall structure has excellent heat insulation, soundproofing, and fireproofing properties.
