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. 58-17869 is known as this type of construction method. In other words, the base frame is vertically extended onto the exterior wall made of dry exterior wall material and extends to the cut edge of the prefabricated exterior wall, and the liner material is fixed horizontally to the foundation either directly or via the 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) In the construction method described in n11, the base frame is not fixed to the foundation, so it lacks stability, and the starting material protrudes outward from the base, and the base frame protrudes from the existing external wall. There was a disadvantage that there was a large difference between the dimensions and the actual size, which made construction difficult and spoiled the aesthetic appearance. Furthermore, there was a drawback that there was no guide at all when fixing the underlying bone, resulting in 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 the mounting body horizontally,
Fit the cut-out part of the lower end of the vertical rim into the notch of this mounting body, fix it vertically at a position corresponding to the frame of the existing external wall, and then horizontally attach the starter 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. It is fixed vertically and functions as a mounting body for the starter and the new exterior wall material.Furthermore, the mounting body closes the opening formed between the lower ends 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, where the soil is the frame of an existing wall, such as studs, and 2 is an existing mortar wall (hereinafter simply referred to as wall) structure. To explain further, the wall 2 is on the outer surface of the frame.
For example, it consists of a mortar wall structure made of wood slate, waterproof sheet, lath sheet, and mortar wall material in the order of 5+. 3
is a foundation, 4 is a foundation, and i is a foundation drainer, which is installed horizontally at the lower end of wall 2 to form the base of a new wall to be described later. To explain further, the foundation drainage work is shown in Figure 2 t.
It is formed as shown in a+ to (e) to strengthen 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. ■ is a mounting body that forms a bonfire 9a at a corresponding position on the frame of the wall 2 as shown in Fig. 3, and mainly closes the opening near the base of the new external wall described later, and also vertically This is for guiding and fitting the circumference of the furring. The river is perpendicular to the position corresponding to the frame of the wall 2 at the vertical edge, and its lower end fits into the notch 9a of the mounting weight, and its back surface abuts the surface of the wall 2, and the nail 17 It is fixed onto the building frame through the

In addition, as shown in Fig. 4, according to the vertical rim rule, a notch 10a is formed at the lower end, which fits into the notch 9a of the mounting weight, and the total thickness is determined by the vertical rim rule. The thickness is the same as that of . ■ is a starter that is fixed horizontally to the lower end of the two vertical rims, 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 something that cannot be prevented. Its shape consists of an elongated body with a cross section as shown in Figure 5 fal~(fl. That is, Figures (a)~(Cj) are of the hook type, (Figures d1~ff1 are of the drop type). Exterior wall material 1
6 is suitable for mounting. Specifically, the nailing steps 1 are formed by roll forming, pressing, etc. a thin metal plate.
2. It is large and consists of a bottom part 13 and an engaging part 14. ■ is a new exterior wall, and the dry exterior wall material I6 is applied horizontally sequentially.
The exterior wall material 16 is shown in Fig. 6(a).
It has a cross section as shown in ~U) and is made of any one of a long composite plate, a single plate (not shown), etc.

The structure of the connecting portion of the outer wall material 16 is either a hook type or a drop type. ! 7: Use nails to drain the foundation, starter plate, installation weight, vertical sillage, exterior wall material 16
It is used for fixing on the building frame. 18 is a waterproof sheet that is used as necessary between the wall 2 and the exterior wall material (6), and mainly functions as a dew condensation prevention material, rust prevention material, waterproof material, and cushioning material for the wall 2. Specific examples include asphalt felt and Kufelt.

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 drain as shown in FIG. The mounting body 1 is placed horizontally on the mounting portion 6 of the
Fix it so that the notches 9a are aligned with the spacing on the frame. Next, the notch 10a at the lower end of the longitudinal rim is fitted into the notch 9a and fixed vertically at the corresponding position to the body. Next, a starter plate as shown in FIG. 5(b) is fixed via nails 17. After that, the outer wall material 16 as shown in FIG. Therefore, in order to form a new outer wall mold, it is sufficient to repeat the steps described above one after another.

(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 does 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 aligned vertically using the mounting body as a guide, and corresponds to the frame of the existing wall. The starter and new exterior wall materials were constructed on the pupil side edge while fixed in position, resulting in a uniform exterior appearance. Furthermore, it is simple and easy to install, as all you need to do is add a foundation drainer, vertical rim, short spacer, starter, and exterior wall material to the existing wall soil, and since the opening at the bottom of the new wall is also closed, there is no possibility of condensation. (The back side of the exterior wall material and the surface of the existing wall are characterized by less deterioration. Also, when the exterior wall is formed using the exterior wall repair method according to the present invention, it has a double wall structure with the existing wall, and has excellent heat insulation, soundproofing, and fireproofing properties.) It is characterized by a unique wall structure.
