A siding wall configured by being joined to the upper end of a siding board 4 is known. This type of siding wall has become widespread in recent years due to its excellent workability, manufacturing workability, and fire resistance.
It had the following problems.

"Problems to be solved by the invention" In the conventional siding wall shown in FIG. Due to the partitioned structure, there is no place for the condensed water that forms in each partitioned space to escape, and as a result, the condensed water stays on the waterproof sheet 2 and the rim 3 that surround the space, causing damage over time. There was a risk that the trunk rim 3 would deteriorate.

``Purpose of the invention'' This invention was made in view of the above circumstances, and is a wall that provides ventilation to the space formed between the siding board and the outer wall to prevent the building materials surrounding the space from deteriorating. The purpose is to provide structure.

"Means for Solving the Problems" The present invention provides a plurality of siding boards arranged vertically on the outer surface of an exterior wall base material, each of which extends in the width direction of the exterior wall. In a siding wall in which the lower end of the upper siding board of the vertically adjacent siding boards is overlapped with the outer surface of the lower siding board, the furring edge is connected to the elongated base body and It consists of a plurality of protruding pieces protruding from one side of the base in the width direction at appropriate intervals in the length direction of the base, and the protruding pieces are attached with the protruding pieces facing downward, while the siding board is attached to the upper end of the base. are positioned and nailed to the protruding pieces, and further, the space between each of the siding boards and the exterior wall base material is vertically communicated through the gaps between the protruding pieces of the furring. It is something.

"Function" The space between the upper siding board and the exterior wall base material is communicated with the space between the lower siding board and the exterior wall base material through the gap between each protruding piece of the rim. , This allows the space to be ventilated.

"Embodiment" FIGS. 1 and 2 show an embodiment of the present invention, in which the outer wall A covers the outer surface of the wall structure 10 with a waterproof sheet (exterior wall base material) 11, and this waterproof sheet 11
The outer surface of the siding board 12 is covered with a plurality of siding boards 12. A plurality of elongated comb-shaped furrings 13 are attached to the outer surface of the waterproof sheet 11 horizontally and with appropriate intervals between them. The furring 13 is constructed by protruding a large number of protruding pieces 13B from one side in the width direction of a rod-shaped base 13A with an appropriate distance S between them. It is brought into contact with the waterproof sheet 11 with the protruding piece 13B facing downward.

The siding board 12 is constructed by pasting a decorative material 12B on the surface side of a substrate 12A, and a side hook-shaped locking piece 1 is attached to the upper edge of the decorative material 12B.
At the lower edge of the decorative material 12B, which slightly protrudes from the lower edge of the substrate 12A, a hook-shaped locking protrusion 12b that can be engaged with the locking piece 12a is formed. And each siding board 12
is the locking piece 12 of the lower siding board 12
The locking protrusion 1 of the upper siding board 12 is shown at a.
2b, while bringing the upper end of the siding board 12 into contact with the outer surface of the longitudinally central portion of the protruding piece 13B of the furring 13, so that the upper end of the siding board 12, the protruding piece 13B of the furring 13, and the waterproof sheet 1
1 into the wall structure 10.

Although it is omitted in the drawing, the topmost siding board 12 of the vertically stacked siding boards 12 is connected to the eaves of the house, and the space on the back side of this siding board 12 is connected to the space behind the eaves. The space behind the eaves is communicated with the outdoors through an opening formed in the eave ceiling material,
A space on the back side of the lowermost siding board 12 connected to the part near the foundation of the house is opened to the outdoors. In addition, since all the spaces on the back side of each siding board 12 fixed as described above are in communication via the gaps S between the protruding pieces 13, 13... of the siding board 13, the siding board On the back side of 12, a ventilation passage T is formed which communicates with the outdoors at the upper and lower parts.

In the case of the exterior wall A configured as described above, the wind blowing around the house blows into the ventilation path T, and moisture does not accumulate in the ventilation path T, so that the surface of the waterproof sheet 11 and the rim 13 are Even if dew condensation occurs on the outer surface or the back surface of the siding board 12, the condensed water will not remain, and deterioration of the waterproof sheet 11, the rim 13, etc. over time due to dew condensation can be prevented.

Further, the rim 13 is preferably made of preservative-treated wood or plastic. Furthermore, the siding board is not limited to the configuration of this embodiment, but may be made entirely of metal, or made of an inorganic material with locking pieces and locking protrusions formed on the board, etc.
It is best to use a widely known general siding board.

FIG. 3 shows another embodiment of the present invention. In this embodiment, an inclined surface 13c that descends as it moves away from the waterproof sheet 11 is formed on the upper surface of the rim 13, and other configurations are provided. is equivalent to the above embodiment.

In this embodiment, when condensed water or rainwater adhering to the waterproof sheet 11 enters and slides down along the waterproof sheet 11, the inclined surface 13c quickly removes the condensed water that has reached the trunk rim 13. Since the dew condensation water is guided to fall below the rim 13, the condensed water is not retained around the rim 13, which is more advantageous in terms of preventing deterioration of the rim 13. Other curing procedures were the same as in the previous example.

Note that the shape of the furring 13 is not limited to a comb shape. Furthermore, in the above embodiment, the waterproof sheet 11 is used as the base material for the outer wall, but the wall structure 1
Of course, there may be cases in which the waterproof sheet 11 also serves as an outer wall base material or a base layer provided on the outer surface of the waterproof sheet 11 serves as an outer wall base material.

"Effects of the Invention" As explained above, the present invention provides a plurality of furring edges extending in the width direction of the outer wall on the outer surface of the exterior wall base material, and a plurality of siding boards are arranged in the vertical direction to form the furring edges. In a siding wall in which the lower end of the upper siding board of the vertically adjacent siding boards is overlapped with the outer surface of the lower siding board, the furring edge is connected to a long base body, A plurality of protruding pieces are provided on one side in the width direction of the base body at appropriate intervals in the length direction of the base body, and the protruding pieces are attached with the protruding pieces facing downward. The upper end portion is positioned and nailed to the protruding piece, and further, the space between each of the siding boards and the outer wall base material is vertically communicated through the space between the protruding pieces of the rim. Because of this, the following excellent effects can be achieved.

(1) Each space on the back side of the siding board is
Because all of them communicate vertically through the gaps between the protruding pieces of the siding board, a ventilation path is formed on the back side of the siding board that communicates with the outdoors at the top and bottom. Ventilation is ensured, the wind that blows around the house blows into the ventilation passages, and moisture does not accumulate in the ventilation passages.

(2) The back side of the siding board has a structure in which the top and bottom are connected to the outdoors through the gap between the protruding pieces of the siding board, so there is no possibility of contact with the exterior wall base material, the outside surface of the siding board, or the outside surface of the siding board. Even if there is condensation on the back side, the condensed water passes through the various spaces on the back side of the siding board and flows down to the outside, so there is no accumulation of condensed water, and there is no possibility of damage caused by condensed water over time. can prevent physical deterioration.

In addition, since the rim has protruding pieces protruding from the base at appropriate intervals, siding can be easily removed by separating the upper end of the siding board from the base and nailing it to the protruding pieces. This has the effect of allowing the siding board to be attached by communicating the space between the board and the exterior wall base material.
