As shown in FIG. 11, the outer wall panels to be joined by real bonding have a male panel 2 and a female panel 3 formed on both longitudinal edges of the outer wall panel 1, and as shown in FIG. Attach the board 1' to the base 4 with the male part 2 facing upward, and join the female part 3 of the upper outer wall board 1'' to the male part 2 to form the actual joint part A. In this way, sequentially from the bottom to the top An outer wall board is installed facing the base 4 to prevent rainwater etc. from entering the base 4.

Recently, a space has been created between the foundation of a building and the back side of the exterior wall material to improve vertical ventilation and dissipate moisture and condensation in the exterior wall panels to the outside air, increasing the durability of the building structure. Ventilation methods have begun to be used.

The above-mentioned ventilation method is carried out in a conventional manner. That is, as shown in the plan view in FIG. 13, pillars 5 of buildings, etc.
An interior material 8 is attached to the inside of the studs 6 via a waterproof sheet 7, but a base 4 serving as a windproof layer is provided on the outside of the waterproof sheet 7 to fill the spaces between the pillars and studs. A base material 9 called a rim or a stud is attached along the pillars 5 and studs 6 to create a double structure, and this base material 9
An outer wall board 1 is attached to the space 10 to form a space 10 communicating in the vertical direction.

[Problem that the invention seeks to solve]

By the way, the above-mentioned commonly used ventilation method requires skilled manpower, and furthermore, there is a lot of wastage of materials, and the cost is high.
There was a drawback.

In view of the above circumstances, the present invention provides a method for fastening external wall boards that does not require skill and allows for easy fastening of external wall boards by creating a space between the back surface of the external wall board and the base surface with a small amount of manpower. The purpose is to provide construction methods.

[Means for solving problems]

The present invention has been made to achieve the above-mentioned object, and the gist of the present invention is to connect the external wall boards to be joined in the horizontal direction by actual joining, and to fasten the external wall boards at a predetermined distance from the base surface. Fastening is a construction method that consists of a chevron-shaped clamping plate that is held along the actual joint of the joined upper and lower exterior wall boards, and a flat plate-shaped locking plate that is secured by touching the base surface with its surface. and a connecting plate part that connects the edge of the back side of the outer wall board of the clamping plate part and the lower edge of the locking plate part, and maintains the distance between the base surface and the back surface of the outer wall board at a predetermined dimension, Additionally, there is a construction method for fastening exterior wall panels using fastening numbers that are integrally formed by bending metal plates.

[Effect]

In the metal fittings used in the construction method of the present invention, the clamping plate part is held between the main joint parts, so movement in the direction perpendicular to the base surface of the upper and lower external wall panels is prevented, and the locking plate part is fixed to the base surface. Since the holding plate part and the locking plate part are integrally connected by the connecting plate part, the distance between the back surface of the outer wall board and the base surface is maintained constant.

〔Example〕

Figures 1 and 2 show the first embodiment of the construction method of the present invention. Figure 1 is a perspective view of the metal fitting B used in this construction method, and Figure 2 is a perspective view of the metal fitting B used in the construction method. Exterior wall board 11.
A partially cross-sectional side view showing the state in which 1't is fastened.
Components that are the same as those in FIG. 8 are given the same reference numerals, and their explanations will be omitted.

The metal fitting 8 is constructed as follows. That is,
Clamping plate part 1 with a chevron-shaped cross section that is clamped along the real joint part A
-1, and a flat plate-shaped locking plate portion 12 that is locked by contacting the surface of the base 4, and the edge 11a of the clamping plate portion 11 on the back side of the outer wall board, and the locking plate portion 12 The lower edge 12a of the upper outer wall board 1'' is connected integrally with the connecting plate part 13.
A rising part 13a is formed by rising along ``a'', and at a point where the rising part 13a passes the level of the innermost part 3a of the female fruit 3, it is bent at right angles to the back surface 1''a and becomes horizontal. Surface part 13
b is formed, and this horizontal surface portion 13b is connected to the lower edge 12a of the locking plate. The metal fitting B consisting of the holding plate part 11, the locking plate part 12, and the connecting plate part 13 is made by bending a single metal plate. The locking plate portion 12 is provided with a screw insertion hole 12b, and a drain hole 14 is provided near the horizontal surface portion 13b and back side edge 11a of the connecting plate portion 13 as required.

To fasten an exterior wall board using the metal fitting B, first, abut the holding plate part 11 of the metal fitting B against the male stud 2 of the lower external wall plate 1',
The locking plate portion 12 is fastened to the surface of the base 4 with screws 15. Next, the female cone 3 of the lower exterior wall board 1'' is fitted into the male cone 2 to clamp the clamping plate part 11, and then the male cone of the lower exterior wall board 1'' is similarly fixed to the base 4 with the metal fittings B. The outer wall is thus formed by attaching the outer wall boards 1 from the bottom upward.

The actual joint A of the outer wall is prevented from moving in the perpendicular direction to the base 4 of the upper and lower outer wall panels 1'' and 1' by the chevron-shaped clamping plate portion 11, and the width of the horizontal surface portion 13b is appropriately selected. 10 can be freely adjusted.Also, when the outer wall receives wind pressure, the outer wall board is pressed, but its supporting force is strong because it is supported by the horizontal surface part 13b perpendicular to the back surface of the outer wall board. Due to the inclination of the outer wall board 1'', the legs 3b of the female nut 3 between the rising part 13a and the clamping plate part 11 are likely to break, but the rising part 13a is above the level of the innermost part 3a of the female fruit 2. Since it is elongated, it has high strength against bending. Further, even if rainwater or the like enters the space 10, the provision of the drain hole 14 prevents it from accumulating on the top surface. Also, as a matter of course, the metal fitting B is
Relatively narrow widths must be used at intervals to provide sufficient communication between the vertical direction of the space 10.

Note that 16 in the figure is a sealing material provided to prevent rainwater etc. from entering the actual joint A.

In addition, Figures 3 and 4 are views corresponding to Figures 1 and 2, respectively, showing a second embodiment of the construction method of the present invention, and the same parts are given the same reference numerals and their explanations are omitted. do.

The connecting plate portion 17 of the metal fitting B+ is formed in a flat plate shape and extends perpendicularly to the outer plate surface from the clamping plate portion 11a, and is connected to the lower edge 12a of the locking plate. This connection plate part 12
A drain hole 14 is provided as necessary.

When the outer wall board is attached using the metal fittings B1, there is no fear that the female leg 3b will break because it will not be caught between the metal fittings. Further, the metal fitting B+ has a simple structure and can be manufactured at low cost, and the installation of the outer wall board is easy because it is only necessary to fit the clamping plate portion 12.

5 and 6 are views corresponding to FIG. 1 and FIG. 2, respectively, showing a third embodiment of the construction method of the present invention, and the same parts are given the same reference numerals and the explanation thereof will be omitted.

The connection plate part 18 of the metal fitting B2 is as follows from the clamping plate part record 11a.
1. A curved portion 18a is formed by leaving the back surface 1''a of the outer wall board and rising up in a curved manner to form a hollow portion 19, and then coming into contact with the back surface 1"a at a position past the level of the innermost part 3a of the female fruit of the lower outer wall board. After forming, bend it at right angles to the back surface 1″a, and
8b, which is connected to the lower edge 12a of the locking plate. Drain holes 14 are provided near the horizontal surface portion 18b and the back side 111a as required.

The above metal fitting B2 is attached to the back of the female part of the lower exterior wall board 1'' and the metal fitting B2
Since the hollow part 19 is formed between the connecting plate part 18 and the curved part 18a, the female nut 3 can be rotated even if the outer wall board is tilted, and the legs 3b will not break.

7 and 8 are views corresponding to FIG. 1 and FIG. 2, respectively, showing a fourth embodiment of the construction method of the present invention, and the same parts are given the same reference numerals and the explanation thereof will be omitted.

The clamping plate part 11 of the metal fitting B3 is vertically divided into three parts, and the central part extends downward parallel to the locking plate part 12 and forms the flat plate 11.
b.

The lower outer wall plate 1' is pushed toward the space 10 by the sealant 16, which may reduce the watertight performance of the sealant and cause water leakage. In addition, even if there is no water leakage, the lower exterior wall board 1
’ upper edge is pressed, and the surface of the lower exterior wall board 1’ is pressed down to the lower exterior wall board 1”
However, the above-mentioned problem can be solved by using the metal fitting B3.

FIGS. 9 and 10 are views corresponding to FIGS. 1 and 2, respectively, showing a fifth embodiment of the construction method of the present invention, and the same parts are given the same reference numerals and the explanation thereof will be omitted.

The clamping plate portion 11 of the metal fitting B4 is vertically divided into two parts, one of which has only a chevron-shaped rising portion 11c.

Generally, exterior wall boards are installed upwards from the bottom, but
When installing walls at the same height laterally, it is common practice to line up adjacent exterior wall panels at the same time and fasten them with metal fittings.

However, when fastening vertically upwards and then fastening the next row vertically, if the end of the metal fittings protrudes from the edge of the external wall board, the clamping plate of the metal fittings will come from the side. It is necessary to fit the upper edge of the adjacent external wall board into the area, which reduces workability.

In this case, about half of the clamping plate part uses the metal fitting B4 of the rising part 11c with the front part removed, leaving only the rising part 11c protruding, and pressing the adjacent external wall board against this,
If the squared part is attached to the base using metal fittings, construction can be performed without reducing workability at all.

〔Effect of the invention〕

As described above, the construction method of the present invention forms an outer wall with a predetermined space between the base surface and the back surface of the outer wall panels by sequentially fastening the outer wall panels from the bottom upward using metal fittings. This method has many advantages, such as making it possible to perform construction using an efficient ventilation method without requiring any manpower.
