Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is capable of accommodating the joint portion of the lateral ventilation passage formed on the lower side of the base and the longitudinal ventilation passage 7 formed on the outer wall, and is efficient. The present invention relates to a ventilation joint member having a water draining portion, which enables the water draining at the lower end of the outer wall to be performed at the same time.

(Problems to be Solved by Prior Art and Invention) Communication between an underfloor space, a lateral air passage formed between a top of a cloth foundation and a base, and a vertically extending air passage formed on an outer wall. For example, the air blown into the underfloor space is made to flow into the longitudinal ventilation passage through the lateral ventilation passage, and is discharged into the space above the ceiling and discharged from the rear attic ventilation hole to the outside. Buildings have been attracting attention in recent years because they can improve the habitability and can exhibit energy-saving effects.

In such an air circulation type building, in order to construct a ventilation joint portion between the lateral ventilation passage under the base and the longitudinal ventilation passage of the outer wall, the lateral ventilation passage and the longitudinal ventilation passage are connected to each other. Two constructions were required: the ventilation joint construction and the construction in which the water drainage at this ventilation joint portion is formed while ensuring watertightness.

The construction procedure of such a ventilation joint part is described in 5th-6th.
It will be as follows if it demonstrates based on a figure.

That is, in order to carry out the construction of such a ventilation joint portion, a lateral ventilation path d is formed by interposing a ventilation base member c between the cloth base top end a and the base b at a required interval and at the outer surface. In the state where the ventilation board f having a large number of protrusions e arranged side by side is attached to the wall base portion, the floating pieces g are fixed to the outer surface of the base b at a required interval in the lengthwise direction. A furring strip h is installed between the floating pieces g ... And a horizontal bar j functioning as a mortar backup material is fixed to the upper end portion of the outer surface of the cloth foundation i. Then, a Z-shaped draining member o formed by bending a rising piece 1 and a falling piece m on the inner and outer edges of the inclined piece k is fixed to the furring strip h at the rising piece l. After that, the outer wall material p is attached so as to cover the outer surface of the ventilation board f and the outer surface of the rising piece l of the draining member o, and the mortar q extends from the outer surface of the horizontal rail j to the lower surface.
The construction of the joint portion is completed by applying. Thus, the airtight joint part s that connects the lateral ventilation path d and the vertical ventilation path r is formed, and the drainage t is formed at the lower end portion of the outer wall.

However, in the case of such on-site construction,
Not only is there a problem that the construction efficiency is low due to the great amount of time and labor required, but there is also a problem that it is not always possible to construct a ventilation joint portion of uniform quality with excellent airtightness, and the construction cost is increased.

Is done as is formed. It should be noted that the groove line 23 provided parallel to the length direction on the upper surface of the inclined piece 20.
Each of the above functions as a ruler for setting the coating thickness when mortaring the outer wall surface. Particularly, in the present embodiment, the rectangular tubular bodies 25 and 26 having the bottom plate 11 as the upper surface portion and the inclined piece 20 as the upper surface portion are provided. Note that the inner side surface portion 27 forming the inner tubular body 25 is provided so as to be slightly more outward than the inner edge 29 of the bottom plate 11, and the inner edge portion 30 of the bottom plate 11 and the inner side surface portion 27 of the inner tubular body 25. Thus, the notch portion is formed as one of the inner edge portions of the bottom plate.

Further, on the inner edge portion of the bottom plate 11, that is, on the inner side surface portion 27 of the inner cylindrical body 25 in this embodiment, a flexible cylindrical airtight holding piece 32 that can be in close contact with the outer surface 31 of the fabric base is directed inward. The airtight holding piece 32 is formed so that its tip portion projects inwardly from the inner surface portion of the inner standing wall 12.

The upper end 33 of the connecting ventilation passage 17 formed by inserting the ventilation member 10 into the fitting portion 15 is formed so as to communicate with the vertical ventilation passage 7 formed on the outer wall.

The procedure for constructing the joint portion 35 of the lateral ventilation passage 5 and the vertical ventilation passage 7 using the ventilation joint member 1 having the above-described configuration will be described below.

First, by interposing the ventilation base member 36 between the cloth base top end 2 and the base 3 at a required interval, the lateral ventilation passage 5 is formed, and a large number of protrusions 37 are arranged side by side on the outer surface side. In the state where the ventilation board 39 is attached to the wall base portion, the main body member 9 is positioned so that the ventilation opening 19 provided in the inner standing wall 12 is in communication with the lateral ventilation passage 5.
The inner standing wall 12 is fixed to the outer surface of the base 3 by using, for example, staples. After that, the fitting portion of the main body member 9

The cylindrical airtight holding piece 32 protrudingly formed on the inner edge portion of the bottom plate 11 is brought into close contact with the cloth base outer surface 31 as shown in FIGS. After that, the outer wall material 40 is formed so as to entirely cover the outer surface portion of the ventilation board 39 and the outer surface portion of the outer standing wall portion 13a of the draining portion 22.
Stick. At the same time, when the mortar 41 is applied to the outer surface 31 of the cloth foundation by causing the airtight holding piece 32 that is in close contact with the outer surface of the cloth foundation to also function as a backup material, the lateral ventilation passage 5 and the vertical ventilation passage 7 are separated. The ventilation joint portion 38 is formed and the drainer 42 is formed at the lower end portion of the outer wall.

FIG. 4 shows another embodiment of the airtight holding piece 32,
The airtight holding piece 32 is formed as a soft tongue piece formed so that its tip portion projects inwardly from the inner surface of the inner standing wall 12. However, by fixing the inner standing wall 12 to the outer surface of the base, the tip side portion 43 of the tongue-shaped airtight holding piece 32 is fixed.
Becomes a curved state and comes into close contact with the outer surface 31 of the cloth foundation. In addition, the tongue-shaped airtight holding piece 32 that is in close contact with the tip portion in this manner is also a backup material when the mortar 41 is applied to the outer surface of the cloth base, as in the case of the tubular airtight holding piece described above. Function.
