[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for an outer wall material in a narrow land.

[0002]

2. Description of the Related Art Conventionally, as a structure of a building outer wall, as shown in FIG. 6, a waterproof sheet or a ventilation windproof sheet or the like is provided on a wall plate mounting base surface comprising a base 2 provided with a base drainer 1 and a stud 5. A so-called dry construction method in which a sheet A is attached and the wall plate 4 is fixed using nails B and the like thereafter is widely known.

[0003]

[Problems of the prior art] By the way, the above-mentioned outer wall structure has no problem if there is enough vacant land around the construction site, but it is very difficult or almost impossible to construct it on narrow lands such as city center. There was a possible problem. That is, in the above-mentioned outer wall structure, since the base sheet A is stuck to the base surface of the wall base, the construction of the wall plate 4 has to be performed from the outside of the building, and the gap between the building and the adjacent building is extremely narrow such as 40 cm or less. When only a space can be secured, it is difficult to even bring in a wall plate, and construction is very difficult or almost impossible. Further, even if the wall plate can be successfully carried in by a loading machine such as a crane, there are various problems such as difficulty in fastening when driving nails into the wall plate 4 because there is no space for a tool such as a hammer. Was.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention has a structure for fixing an outer wall material in a narrow land where a wall plate can be fixed with good waterproofness even when the space between adjacent buildings is extremely narrow. The purpose of this is to provide.

[0005]

A resolution means for That is, the fixing structure of the outer wall material in narrow locations this invention is the foundation basis 2 provided with the base draining 1, the fixed piece 3A along the upper surface 2A of the base foundation 2, wherein along the outer surface of the base foundation 2, or one wall plate 4 bottom and support fittings 3 having a folded portion 3E on the lower side 3B to engage the fixing piece 3A portions on the upper surface of the base foundation 2 2
Is fixed to the A, the support hardware is the third folded portion 3E is engaged the lower end supporting said wall plate 4 is vertically opposite ends 4A of the wall plate 4 supported at the lower end, 4B is the wall plate 4 ends Fitting portions 6A and 6 of the vertical jointer 6 having a cross section of "E" shape fixed vertically along the stud 5 positioned at
It is inserted into and supported on the B, section L of the intermediate portion of the wall plate 4 along the studs 5A side and the wall plate back surface 4C between the studs 5
It is supported by the shaped fastening bracket 7, the vertical joints 4D, and a vertical joint Joyner 6 and the wall plate back surface 4C and an L-shaped fastening bracket 7 the wall plate back surface of said wall plate 4 4C
The sealing material 8 is filled between them.

[0006]

Next, an embodiment of the present invention will be described. FIG. 1 is a longitudinal sectional view of an embodiment of the present invention, FIG. 2 is a transverse sectional view of the embodiment, and FIGS. 3, 4 and 5 are enlarged sectional views of essential parts of the embodiment.

[0007] fixing structure of the outer wall material in narrow locations this invention is the foundation basis 2 provided with the base drainer 1, the Soil
A fixing piece 3A along the upper surface 2A of the base foundation 2, wherein the base foundation <br/> along the outer surface, or One the wall plate 4 bottom and support fittings 3 having a folded portion 3E on the lower side 3B to engage the Fixing piece 3
Is fixed to the upper surface 2A of the base foundation 2 in part A, the wall plate 4 a lower end engaged with the folded portion 3E of the support fittings 3 are made connected in the vertical direction is vertically supported.

[0008] Both ends 4A and 4B of the wall plate 4 whose lower end is supported are vertically joined along a stud 5 positioned at both ends of the wall plate 4 and have a vertical joint part 6 having an E-shaped cross section. Of the wall plate 4 is inserted into and supported by the fitting portions 6A, 6B.
C, and is supported by a fastening member 7 having an L-shaped cross section along C, and as shown in an enlarged view in FIG.
D, between the vertical jointer 6 and the wall plate back surface 4C as shown in an enlarged view in FIG. 4, and as shown in an enlarged view in FIG. Sealing material 8 is filled between back surface 4C. In addition,
In the figure, 7A is a nail for fixing the fixing member 7 to the side surface of the stud 5;
Denotes a screw or a tapping screw for fixing the fastening member 7 to the back surface of the wall plate 4.

In the above embodiment, the foundation 2 has the same structure as the conventional one in which the foundation girder 2B is fixed on the concrete foundation 2A with anchor bolts or the like. The supporting metal 3 depends on the total weight of the wall plate 4 to be supported, but if it is lightweight, it is formed by bending a thin metal plate, and if it is heavy, it is made of aluminum light alloy or steel. .

[0010] The wall plate 4 is fiber-reinforced cement board is used, the engaging stepped portion fitted form male and female relationship is provided on its upper and lower ends. Note that the shape of the engaging step portion is the shape of the wall plates 4 and 4.
When they are connected to each other, it is preferable that the upper side wall plate 4 is of a type in which the upper side wall plate 4 is independently supported by the engaging step portion of the lower side wall plate 4, for example, a real engaging step portion.

When the wall plate 4 is nailed to the stud 5, the nail is fixed by driving a nail in an oblique direction as shown by a chain line in FIG. When fixed in this way, even if the gap between the adjacent building (not shown) is narrow, it is easy to drive it in from the inside of the building with a hammer or the like. can get.

[0012]

In the structure for fixing an outer wall material on a narrow land according to the present invention, no base sheet such as a waterproof sheet is used on the base surface to which the wall plate 4 is fixed, so that the wall plate 4 is fixed from the inside of the building. It becomes possible. Also, since the sealing material 8 is filled in the joint between the wall plates 4 and 4 and the joint interface between the vertical jointer 6 and the rear surface 4C of the wall plate, the base sheet such as a waterproof sheet is not used at all. Regardless, good waterproofness can be obtained. In addition, since the middle portion of the wall plate 4 is fixed to the stud 5A or the like by the fastening member 7 having an L-shaped cross section, deformation such as warpage is prevented.

[0013]

[Effects of the Invention] Since the invention of the present invention is constructed as described above, construction can be performed from the inside of the building even on a small land, and construction of the outer wall, which has been difficult in the past, becomes very easy. In addition, since a base sheet such as a base sheet is not used, the structure of the outer wall becomes simpler and the outer wall can be constructed at low cost. Further, although the base sheet is not used, each joint portion is filled with the sealing material 8, so that there is an effect that the waterproof property is good.
