〔Example〕

Hereinafter, different embodiments of a ventilation structure member and a ventilation structure according to the present invention will be described in detail with reference to FIGS. 1 to 8.

FIG. 1 shows a first ventilation structure member according to the first invention.
FIG. 2 is a cross-sectional plan view of the above-lined portion; FIG. 3 is a perspective view showing a connecting member for connecting the ventilation structure members to each other; FIG. 4 is a perspective view of each of these members. A front view showing an embodiment of the ventilation structure according to the second invention configured by integrally combining the
Figures 5a and 5b are enlarged longitudinal sectional side views of the Va-Va and Vb-Vb line sections, respectively, and Figure 6 is a partial plan view showing details of the connecting parts when the ventilation structures are connected in the longitudinal direction. It is.

First of all, in the configuration of the first embodiment of the first invention shown in FIGS. Above and below each base 21, 21, respectively, bulges 23, 23 and guide portions 24, 24 extending obliquely outward, and above each bulge 23, 23, respectively. The connecting portion 22 has shielding portions 25, 25 extending inward at an angle, and has an appropriate number of vertical communication holes 26 and mounting holes 27 at a plurality of predetermined positions.

Here, the pair of base parts 21, 21 are made up of vertical parts 21a, 21a extending vertically at a predetermined height and facing each other at a predetermined interval, and the connecting part 22 is , the substantially middle portions of these facing vertical portions 21a, 21a are connected to each other by a relatively thick horizontal portion 22a for reasons such as maintaining strength, and with this configuration, A type of groove-like space 28, 29 is formed above and below surrounded by each of these parts.

Further, each of the bulging portions 23, 23 includes inclined portions 23a, 23a which are expanded outward and upward by a predetermined length from the upper end of each of the vertical portions 21a, 21a, respectively, and each of the inclined portions 23a, 23a. part 2
Vertical portions 23b, 2 that extend upward from the ends of 3a, 23a so as to face each other at a predetermined height.
3b, and the ends of the respective vertical portions 23b, 23b as the respective shielding portions 25, 25,
Together with the inclined portions 25a, 25a which are each narrowed toward the outside by a predetermined length, it is surrounded by these portions, and is directly inserted into the space 28 and through the communication hole 26 into the space 29. , a bulge-shaped space 30 is formed that is continuous with each other, thereby making the top and bottom of each space open.

Furthermore, each of the guide portions 24, 24 is comprised of an inclined portion 24a, 24a which is expanded outwardly and downwardly by a predetermined length from the lower end of each of the vertical portions 21a, 21a.

It is preferable that each of these parts 21 to 24 be formed into a series of elongated pieces by extrusion molding of an aluminum material, for example, by cutting the same member into a predetermined size and forming the communication hole 26 and the mounting hole. It is effective to form a product by drilling holes 27, and in this way, the ventilation structure member 20 can be constructed integrally.

In this embodiment, the communication hole 26 and the mounting hole 27 are formed separately, but as will be described later, a part of the communication hole 26 can also serve as a corresponding part of the mounting hole 27. In this case, in principle, it is sufficient to punch out at least only the communication hole 26.

Therefore, in the ventilation structure member 20 according to the first embodiment of the first invention, the base 21, the bulging part 23, the guide part 24, and the shielding part 25, which form a pair, are connected to the base 21. Since the parts are connected by the connecting part 22 and at least the communicating hole 26 is opened in the connecting part 22, a series of spaces 28 with upper and lower sides open as a ventilation structure are created inside surrounded by these parts. 30 can be integrally formed, and as will be clear from the explanation below,
When used with one side facing outdoors, the shielding part 25 prevents rainwater blown from the outside into the upper opening from directly entering the surface of the bulging part 23. The guide part 24 is located at the upper part of the space 30 and directs the rainwater flowing down the surface of the bulge 23 to the outer side of the space 30 as much as possible. Furthermore, the inner surface of the inclined portion 23a of the bulging portion 23 serves to effectively direct the rainwater that has flowed in from the space 28 to the space 29 side through the communication hole 26, and to weaken the force and drain it out. Moreover, in the ventilation structure member 20 configured in this way, unlike the conventional example, the entire structure can be integrated without using any fixing bolts or nuts.

Next, in FIGS. 3 to 6, the ventilation structure 35 according to the embodiment of the second invention has a plurality of ventilation structure members 20 corresponding to the required number of ventilation surface stages as shown in FIG. The required number of connecting members 36 shown
and fixing bolts 38 with a predetermined effective length corresponding to the required number of stages shown in FIGS. Here too, the whole is integrated and constructed.

Here, the coupling member 36 has a hollow rectangular tube shape with a mounting hole 37 formed in the center in the axial direction, and the width of one side of the outer surface thereof is the same as that between the bases 21 and 21 of the ventilation structure member 20. As is clear from FIG. 6, each end face fitting member 40, 42 is set to have a dimension that allows it to be inserted into the ventilation structure member 20, and as is clear from FIG. One member 40 has a protruding strip 41 and the other member 42 has a concave strip 43 at the center of the end face in order to enable the two members to be fitted and connected to each other. The protruding stripes 41 and the grooved stripes 43 are formed so that they can be engaged with each other.

And each of these members 36 and 40, 42
Similarly to the above, it is desirable to form a series of elongated members by extruding an aluminum material, for example, and it is effective to use the same member by cutting it into a predetermined size.

Note that the end face fitting members 40 and 42 are literally members for fitting and covering both end faces of each of the ventilation structure members 20 arranged in tiers in a well-fitting manner. Depending on the situation, it may be possible to use one without the protruding strips 41 and the concave strips 43, or to omit them altogether. This is convenient when the two are connected in the longitudinal direction.

Therefore, when the ventilation structural members 20 are assembled in stages, the upper and lower portions of each ventilation structural member 20 corresponding to the mounting holes 27, that is, the corresponding portions of the groove-shaped spaces 28 and 29 in this case, By inserting the upper and lower ends of the coupling member 36 into each of the shielding parts 25, 25 of the lower part 20, the guide parts 24, 24 of the upper part 20 are superimposed so as to overlap. , the space portion 30 is provided between the tip of each shielding portion 25, 25 and the outer surface of each base portion 21, 21.
A number of external and internal openings 44a and 44b corresponding to the number of stages are formed, and these mounting holes 27 and 44b are formed from below to communicate with each other.
A long fixing bolt 38 is inserted through the bolt 37 and tightened with a nut 39 to form an integrated structure. By tightly bonding the members 40 and 42, the desired ventilation structure 35 is constructed.

Therefore, when the ventilation structure 35 according to the embodiment of the second invention assembled in this way is applied to a building, as shown in FIG. Between the external and internal openings 44a and 44b, for example, as in the conventional example described above, the solid line path a provides ventilation inside and outside, and the dotted line path b removes rainwater from the outside. In addition to the above-mentioned effects on the individual ventilation structural members 20, the whole can be integrated and connected with a small number of fixing bolts and nuts with simple work. can.

Furthermore, FIG. 7 shows a second embodiment as a modification of the ventilation structure member 20, and in this second embodiment, the pair of bases 21, 21
, the upper and lower two connecting parts 22 have the same thickness as the other parts.
By configuring it in this way, on the one hand, the connection strength between the respective base parts 21, 21 can be maintained sufficiently, and on the other hand, the thickness of each part of the member can be made constant, making it possible to perform this type of extrusion. This makes it easier to mold the mold material.

Subsequently, the ventilation structure 50 according to the embodiment of the third invention shown in FIG. A similar arrangement, i.e.
The individual ventilation structural members 20 are arranged in multiple stages in the vertical direction, and between each shielding part 25, 25 of the lower part member 20,
The guide portions 24, 24 of the upper member 20 are overlapped so as to overlap each shield portion 25, 25.
External and internal openings 44a, 4 that communicate with each other are provided between the tips of the bases 21, 21 and the outer surfaces of the bases 21, 21.
4b, and in this arrangement, the ventilation structure members 20 of each stage are installed as appropriate in the part of the building to be ventilated, in other words, in the roof opening in the conventional example, etc. They are individually attached and fixed to the support members 51 and the like that are provided with bolts and nuts 52, and in the case of this third invention as well, the same functions and effects as described above can be achieved. There is no need to interconnect the ventilation structural members 20 of the invention.

In each of the above embodiments, the ventilation means according to this proposal is mainly applied to a ventilation opening in a roof structure of a building.
Of course, it can also be applied to any other ventilation openings.

〔Effect of the invention〕

As detailed above, according to the present invention, as a ventilation structural member, a pair of base, bulging part, guide part, and shielding part are integrally connected at the base part by a connecting part, and Since communication holes are opened at least in the connecting parts, a series of spaces with an open top and bottom ventilation structure can be formed on the inside surrounded by these parts, allowing for good ventilation. In addition, because of this symmetrical configuration, when one side is used facing outdoors, the shielding part prevents rainwater blown into the opening from the outside and prevents the bulge. The rainwater that flows out to the surface side of the part and flows down inside the space by the guide part can be effectively removed to the outside through the communication hole. Moreover, since the whole is integrated, the structure of the part itself can be simplified. In addition to being extremely easy to install in areas to be ventilated.

In addition, in the ventilation structure, the ventilation structure members of the above structure are arranged in multiple stages in the vertical direction, and each guide portion of the upper ventilation structure member is inserted between each shielding portion of the lower ventilation structure member by intervening the connecting member. However, the ventilation structural members of each stage can be integrally connected to each other by overlapping them at predetermined opening intervals, or the ventilation structural members of each stage can be connected to supporting members of the area to be ventilated, etc. Since it is attached directly to the floor, it is possible to form a series of open spaces as a ventilation structure between each stage and each stage, which not only provides ventilation from inside and outside, but also removes rainwater from the outside. It has excellent features such as being able to achieve the desired effects accurately and further promoting the above-mentioned actions and effects.
