Description

BOTTOM VENTILATION TUBE

The present invention relates to a bottom floor ventilation pipe for buildings where there is a solid space under the cable base, comprising a horizontal pipe passing through a plinth of the building, a vertical pipe connecting to the horizontal pipe, and a protective cap to prevent debris and rain. having a vent on the side facing away from the building, allowing the air to enter and exit the ventilation duct.

Previously known and in use base vents are made of ordinary circular plastic or steel tubes, and have an inverted cup-shaped protective cap larger than the diameter of the vertical tube, whereby the passage of ventilation air is limited to the outer wall of the protective cap and the vertical tube. The problem with such a design is that warm air remains inside the protective cap and no ventilation actually occurs. This has been confirmed, for example, in official investigations commissioned by the Ministry of the Environment.

It is an object of the present invention to provide a ventilation duct with good ventilation properties. This is accomplished by a vent pipe, which is characterized by a closed protective cap and a vertical section in the form of a flattened circle on the side of the building with a wide vent opening in the side wall of the protective cap. laterally over about 25 sectors about 180 °.

Depending on the location of the ventilated subfloor, the vent pipe can be routed through the plinth of the building, either above or below the ground.

Preferably, an outer ring flange is mounted on the horizontal pipe casing at such a position that the ring flange is positioned against the plinth of the building when installing the vent pipe, thereby preventing water from entering the plinth.

Preferably, the vent pipe is made of plastic by injection molding, whereby the pipe can be made to the desired shape. Preferably, the horizontal tube is completely circular in cross-section and is formed at its outer end with a body forming the lower part of the vertical tube, with a water socket and an outlet hole at the bottom for removing condensation and any rainwater.

The length of the vertical tube is freely selectable. It preferably consists of the aforementioned lower part, the middle part and said protective cap. For example, the length of the vertical tube may be varied by cutting off the center section at a suitable point or possibly leaving the center section completely off and installing a protective cap directly over the lower section.

The required length of the vertical tube depends on whether the vertical tube is underground or • above the ground and how thick a layer of snow can be expected with this mounting bracket. Namely, the ventilation pipe must be installed so that its ventilation opening is always located above the snow cover.

Injection molding technology allows the ventilation pipe to be easily colored to the wall of the installation site, thus minimizing attention when installed.

5 For sale, the vent pipe can be packaged in a complete package that includes mounting screws and installation instructions. For shelving, ventilation pipes can be manufactured, for example, in two different pipe sizes, 110 and 160 mm, and in six different colors.

In the following, the invention will be described in more detail with reference to the accompanying drawing, in which FIG. 1 shows an example of a ventilation pipe according to the invention, seen from the side, FIG. Fig. 2 is a front view of the ventilation pipe of Fig. 1, fig.

1-4, the bottom floor ventilation pipe comprises a horizontal pipe 1, which is a • · • ·, ** | made to pass through a plinth 2 of a building where under the rope base 3 is a closed space 4, which must be ventilated to prevent moisture and odor damage., • ♦ a vertical pipe 5 connected to the hood 1 and mounted at its upper end protective hat 6.

. ·. ·. 25 The shield 6 is closed at its upper end and has a vertical section 5 • · · • ·. 1 · ·. shaped such that the vertical portion of the vent pipe has a length of ···. 1. same size cross-section. The side wall of the shield hat 6 has a wide ventilation opening 8 on the front side thereof, i.e., 4 facing away from the building, covered by the grille 7.

In the illustrated embodiment, the vertical pipe 5 and the protective cap 6 of the vent pipe are shaped in a circular cross-section from the side of the building wall 9, which allows the vertical pipe 5 and the protective cap 6 to protrude from the building wall 9 as little as possible.

Depending on whether the ventilated space 4 is located above ground 10 (as in Figures 10 and 4) or below (as in Fig. 6), the horizontal pipe 1 of the ventilation pipe is respectively passed through a plinth 2 of the building above or below ground 10. Preferably, the horizontal pipe 1 is completely circular in cross-section and has an outer annular flange 11 formed on its casing which, when the ventilation pipe is installed, is intended to rest against the plinth 2 of the building and thereby prevent water from flowing along the horizontal pipe 1 into the plinth.

The vent pipe according to the invention is preferably made of plastic by injection molding technology. At the outer end of the horizontal pipe 1 is formed a body forming a lower part of the vertical pipe 5, with a water socket and an outlet hole at its lowest point: to remove condensation and any rainwater.

According to a preferred embodiment, the vertical pipe is made of three parts, such that it consists of said lower part 5a, middle part 5b and said protective cover 6. As a condition for trouble-free operation of the ventilation duct, the protective cap • · ·. · · 25 6 is located so high that it is never covered by snow. Because of this, the length of the vertical tube 5 can be varied by installing the entire central portion 5b of the vertical tube 5 ', or cutting the central portion 5b to the desired size, for example to half its length, as shown in Figure 5, or omit the entire central portion 5b and.:. install the protective cap 6 directly over the lower part 5a.

···· ....: so

In order to achieve the best possible ventilation effect, the wide ventilation opening 8 in the side wall 6 of the protective cap 6 extends laterally over a sector of approximately 180 °, with all wind blowing on the wall 9 of the installation site Ventilation performance is also affected by the construction of the grille 7 covering the vent 8. In the preferred embodiment shown, said sash 5 comprises a plurality of horizontal outwardly projecting slats that allow ventilation air to enter and exit the ventilation duct, but effectively prevent debris and rain from entering the ventilation duct.

The upper surface of the protective cap 6 is also configured to be slightly outwardly inclined so that the rainwater 10 applied thereto flows outwardly from the vent pipe and not into the gap between the vertical pipe 5 and the wall 9 of the building.

Injection molding technology allows the vertical pipe of the vent pipe to be provided with integrated wall brackets 13a, 13b during manufacture to secure the vent pipe-15 to the building wall 9. The central part 5b of the vertical pipe 5 can preferably be provided with at least two wall brackets 13b wall bracket 13b.
