点があった。However, this structure has drawbacks that the cost is huge, the repair period is long, and the residence must be stopped. Further, the structure of (3) is not only difficult to apply to concrete or the like and is inferior in workability, but also has disadvantages such as waterproofness, dew condensation, corrosion of a fixture due to impermeability, and lack of heat insulation.
Further, in the structure of (1), since the C-shaped channel is usually used, it is necessary to fix the portion of the dry type outer wall material that comes into contact with the furring strip with tapping screws. As a result, the work efficiency is poor, and there is a disadvantage that it is necessary to form a large fool hole especially when the expansion is large due to heat like aluminum. In addition, there is a large void between the existing outer wall and the new outer wall material, which is a drawback that the function of the outer heat insulating structure is poor.
本発明はこのような欠点を除去するため、胴縁を少なく

たものである。An embodiment of a repaired outer wall structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 (a) is a partially cutaway perspective view showing a case where a refurbished outer wall according to the present invention is applied to a concrete wall, and 1 is an existing outer wall, such as a concrete wall, a mortar wall, a tile wall, or a block wall. It consists of seeds. 2 is the furring strip (horizontal furring in the figure), and the existing outer wall 1
It is arranged on the upper side at a predetermined pitch P 1 and is fixed to the existing outer wall 1 via a fixing tool 6 such as anchor bolts, nails (only for a mortar wall). Reference numeral 8 denotes a clip, which is made of one kind of steel plate and aluminum, is mainly made of an elastic and rigid material, and has sufficient elasticity for holding. 13 Male / female connection type dry outer wall material. To further explain,
2 has a structure shown in FIGS. 2 (a) to (d), in which a mounting portion 3 composed of a vertical piece 3a for mounting a clip, a horizontal fixing portion 4 for reinforcement, and an appropriate pitch for the fixing portion 4 are provided. Fixed with P 2 (welding,
The mounting legs 5 are also bonded and fixed (including fixing by screws (not shown), bolts, nuts, etc.). More specifically, the mounting portion 3 has a second shape.
As shown in (a), (d) and FIG. 3 (a), for example, a vertical piece 3a having a substantially N-shaped cross section and a flat vertical piece formed separately.
3a, etc., which is fixed and adhered to one side wall of the fixed portion 4,
They are integrated by fastening. Further, the mounting portion 3 is a vertical piece as shown in FIGS. 2 (b), (c) and 3 (b).
The member 3a and the mounting portion 3 are combined into one member, and the structure is advantageous for weight reduction and cost reduction. Further, the fixed portion 4 has at least a horizontal surface 4a as shown in FIGS. 2 (a) to (d) and FIG. 3 (b), and an L-shaped reinforcing portion 4b is formed if necessary. It was done.
The mounting portion 3 and the fixed portion 4 are formed by molding, extruding, etc., a shape steel, a steel plate (a plate thickness of 2 to 5 mm), and aluminum as shown in the drawing. The mounting leg 5 is a metal fitting having an L-shaped cross section for fixing the furring strip 2 to the existing outer wall 1 via anchor bolts and nails (only in the case of a mortar wall) mounting tool 6, and if necessary. The mounting hole 5a. Of course, the mounting legs 5 are short, and the space 7 formed between the mounting legs 5 on the surface of the existing outer wall 1 and between the fixed portions 4 as shown in FIG. 1 (b) is used for an air cycle. It is a thing. As shown in FIGS. 1 (a), (b), and FIG. 4, the clip 8 is for attaching and mounting the dry outer wall material 13 and the furring strip 2 integrally under elastic force without using nails. The material is an elastic material, for example, a metal material, a synthetic resin material, or a laminated or composite of two or more kinds.
It has a thickness of 0.3-1mm.
Rank is preferred. To further illustrate, the clip 8 is fixed portions 13 of the U-shaped specific clamping portion 9 and a dry exterior wall member 13 for clamping resiliently under no withdrawal clips 8 itself to the mounting portion 3 of the furring strip 2
It is formed integrally with a flat plate-shaped insertion portion 10 that holds a. The size Δt of the gap 11 is determined by the plate thickness of the mounting portion 3 and the added state of elasticity, and the heights h 1 and h 2 are set according to the clamping force and rigidity, and l 1 and l 2 are about 10 to 50 mm. Rank. Reference numeral 12 denotes a ventilation layer, which is a space formed between the back surface of the dry outer wall material 13 and the existing outer wall 1, and is communicated through the void 7 or between the back surfaces of the dry outer wall material 13. . The dry type outer wall material 13 is made of one kind of a metal siding material 14 and a ceramic siding material 18, as shown in FIGS. 5 (a) and 5 (b). In particular, the metal siding material 14 is formed by integrally forming a surface material 15, a core material 16 made of plastic foam, and a back material 17 as shown in FIGS.

To do. Therefore, the scaffold is assembled around the existing outer wall 1, and then the furring strip 2 as shown in FIG. 2 (a) is fixed to the existing outer wall 1 via a fixture (anchor bolt) 6.
Next, the metal siding material 14 is arranged vertically and its fixing portion 13
A is attached to the attachment portion 3 of each furring strip 2 with a clip 8 (stainless steel plate having a thickness of 0.5 mm) shown in FIG. 4, and is sandwiched under elasticity. Therefore, in order to form the new outer wall 19, such steps may be sequentially repeated from one direction to the other. In addition, a well-known accessory (not shown) should be installed on the base, the exit, the corners, or around the window, or those that can be installed after the metal siding material 14 can be installed last, and the caulking material is filled in the necessary places. It is a thing. The above described is only an example of a refurbishment external wall structure according to the present invention, the clip 8
Can also be formed as shown in FIGS. 7 (a)-(i). It is to be noted that FIG. 9A shows a clip 8 which is bent to make it easy to insert one piece of the holding portion 9, (b), (c), (d),
(F) is a clip 8 in which an add-on fold 8a, a recess 8b, and a rib 8c are formed for strengthening the engaging force, (h) is a clip 8 used when pulled up from the opposite direction, (i) is an insertion part It is a clip 8 in which the tip of 10 is bent to act as a stopper and a guide. The sandwiching portion 9 of the clip 8 may be mounted so that the dry outer wall material 13 is mounted on the furring strip 2 and then tightened with a tool to further strengthen the sandwiching force. Also, the seventh
When the clip 8 shown in FIG. 6G is used, the furring strip 2 can also be used as a vertical furring strip.
