外壁構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is effective for attaching a dry type outer wall material to a furring strip on an existing outer wall through a special clip instead of a nail and is effective between the existing outer wall and the new outer wall. The present invention relates to an outer wall structure modified to have an air cycle space.

造のいずれかであった。To refurbish the outer walls of existing buildings and houses, a structure in which all the outer walls are removed and a new wall is formed, the existing outer wall is used as a base, and the dry outer wall material is directly fixed to this with nails, the existing outer wall Wooden furring strip, C-shaped furring strip fixed with nails and anchor bolts, dry outer wall material fixed with nails, screws, etc. The existing outer wall and new outer wall are separated by a horizontal furring strip. It was one of the structures that blocked the air cycle.

不利があった。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.
In addition, since the C structure normally uses a C-type channel, the cost is high and there are many construction sites. In addition, the dry outer wall material was fixed by tapping screws at the portion in contact with the furring strip. 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. further,
In this structure, since air does not flow between the old and new outer walls, the dew condensation water generated on the back surface of the outer wall material connection part or the rainwater leaking from the outer wall material connection part is stored on the back surface of the new outer wall and corrodes the furrows, nails, etc. There was a flaw. Of course, there is a disadvantage that water vapor from the inside of the room that evaporates from the surface of the existing outer wall damages these components.

It proposes a refurbished outer wall structure in which the existing outer wall and the new outer wall are formed into an air cycle structure, in order to reduce the cost by further installing it and to shorten the construction period, without requiring skill in construction. .

に形成したものである。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 is a partially cutaway perspective view showing a case where a refurbished outer wall according to the present invention is constructed on a concrete wall, and 1 is an existing outer wall, for example, concrete, mortar, ALC, tile, block, dry outer wall material, etc. It consists of seeds. Reference numeral 2 denotes a furring strip, which is fixed on the existing outer wall 1 at a predetermined pitch via fixing tools α such as nails and anchor bolts. To further explain, the furring strip 2 is the second
As shown in the figure, the mounting piece 3, the bottom side 4, and the tip of the bottom piece 4 are formed in parallel with the mounting piece 3 and a fixing portion 5 extending in the opposite direction to the mounting piece 3 to form a deformed N-shaped cross section as a whole. At the same time, ventilation holes 6 for air cycles are formed in the bottom piece 4 at an appropriate pitch, and mounting holes 7 are provided in the fixing portion 5.
The vent holes 6 and the mounting holes 7 are not limited to the circular shape, but may be oval,
It can also be formed in a polygonal shape or a polygonal shape. . Also furry
2 is a metal plate (Al, Fe, stainless steel, galfan, galvalume steel plate, etc.) roll-molded product, extruded product, injection-molded product. The plate thickness is about 1 to 5 mm, preferably the width of the hat channel. It is good to cut in half in the direction. Further, the length L of the furring strip 2 is about 1800 to 7272 mm, and the widths W 1 and W 2 are 10
The height H is about 0.5 to 50 mm. Reference numeral 8 denotes a clip, as shown in FIG. 3, which is an elastic material, for example, a metal material, a synthetic resin material, or a laminated composite of two or more kinds, and is composed of a holding portion 9 and an insertion portion 10. As shown in FIG. 1, the dry outer wall material 12 is attached to the furring strip 2 without using nails. More specifically, the clip 8 has a U-shaped holding portion 9 for holding the clip 8 itself on the mounting piece 3 of the furring strip 2 without elastically separating it, and a dry outer wall material 12 described later.
The flat plate-shaped insertion portion 10 to be inserted into the fixed piece portion 12c is integrally formed. The size Δt of the void 9a is determined by the charging portion.
Determined by the plate thickness of 10 and the added state of elasticity, 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. Reference numeral 11 denotes a ventilation layer, which is an air layer formed between the existing outer wall 1 and the new outer wall 13 and connects all the spaces through the ventilation holes 6 of the furring strip 2 . Further, the dry type outer wall material 12 is shown in FIG.
As shown in (g), it is made of one kind of metal siding material 12a and ceramic siding material 12b, and is mainly laid vertically. In particular, the metal siding material 12a is formed by integrally forming the surface material 14, the core material 15 made of plastic foam, and the back surface material 16.

Therefore, the scaffold is assembled around the existing outer wall 1 , and then the furring strip 2 as shown in FIG.
It is fixed to the existing outer wall 1 via (anchor bolt). Next, the metal siding material 12a is arranged vertically, and the fixing piece portion 12c is attached to the attaching piece 3 of each furring strip 2 by the clip 8 (made of stainless steel having a plate thickness of 0.5 mm) shown in FIG. is there. If necessary, the clip 8 can be made narrower with a tool to narrow the gap 9a to enhance the gripping force. Therefore, in order to form the new outer wall 13, such a process may be sequentially repeated from one direction to the other direction. The base,
A well-known accessory (not shown) is applied to the exit, entry corners, and windows, or the metal siding material 12a that can be applied after the application is applied last, and caulking material is filled in the necessary places. As a matter of course, the base and the accessory on the shaft top side are those having a vent, or those formed so that the vent can be opened and closed.

That is, the figure (a) shows a furring strip 2 which is effective when the clip 8 is engaged with the through hole 3a of the mounting piece 3 and the new outer wall 13 is laterally stretched, and the figures (b) and (c) show the clip 8. The shape of the furring strip 2 has notches 3b and recesses 3c as guides and stoppers so that it can be more strongly clamped by the shape of Fig. 2 , (d) and (e). The furring strip 2 has ribs 3e and 3d. Further, the clip 8 is determined according to the furring strip 2 and the dry outer wall type 12 as shown in FIGS. 6 (a) to 6 (h). Adder folds, ribs, bends, etc. may be damaged by reinforcement and other members. It is provided in order not to give. The clip 8 shown in (g) and (h) is used for horizontal lining. Further, as the metal siding material 12a, a member for lateral lining as shown in FIGS. 7 (a) to 7 (h) can be used. Other,
A cushioning material (indicated by a chain double-dashed line in FIG. 2) may be continuously or partially provided on the furring strip 2 to add vibration damping properties.
