The boiler room must be equipped with a device which guarantees unhindered access to the combustion air required by the boiler. Dios generally happens in '11 through an opening made in the outer cellar wall, through which the outside air enter and with the help of a on the inside wall of the cellar in the vicinity of the shaft the basement floor can be forwarded. The manufacture of a u-type ventilation device using of bricks, sheet steel, asbestos-cement pipes and the like. more is labor intensive and costly.

The subject of the present application is a ventilation shaft made of prefabricated concrete parts, which is also used by Hichtfachleuten is easy and inexpensive to manufacture. A special advantage of this one composed of prismatic hollow bodies Shaft consists in the fact that only two types of shaped stone are required for its construction, namely "channel stones" and "corner stones". Height and width dimensions of both types of shaped stone are equal to each other, preferably the size of 1-stone thick masonry is chosen. The clear cross-section the shaped stones is rectangular and corresponds in terms of its size to that of the cross-section of the Chimney-dependent requirement. The channel stones can be used without any significant change in the form of manufacture Height all around with a triangular hat, which makes it possible, if necessary, a normal stone in two To dismantle half-stones. In this way, both for the wall breakthrough and for the shaft height above the basement floor all common dimensions (1-stone, 1 1/2 stone, 2-stone, etc.) to achieve.

In the attached drawing, a ventilation shaft is made Precast concrete shown, and zv \, j? demonstrate:

Fig.1- $ : the one made from "channel stones" a and "corner stones"b; composite ventilation shaft in elevation, side elevation and floor plan,

Fig. 4: a canal stone in parallel perspective with an in half the height of the outer wall running triangular! Groove for separating the stone into two half stones.

The breakthrough through the, for example, 1 1/2 stone strong Basement exterior wall is using a whole and a half a-stone lined. This is followed in the interior of the cellar by the one from the upper corner stone b, the one required in each case Number of channel stones a and the lower corner stone b as a shaft foot composite vertical shaft part. The remaining The difference in height between the basement floor and the lower edge of the shaft foot is compensated for by half an a-brick.

In the case of boiler rooms located deep in the ground, the ventilation shaft can be extended upwards with the help of a corner stone b 'arranged on the outer wall and one or more channel stones a ^J - (both indicated by dash-dotted lines in the drawing).

A threshold d made of mortar is provided in the corner stone at the shaft foot, which is carried approximately by the draft Holds back dust.

Accumulating condensation water can be drained off through slots e_ will.

The inlet cross-section of the channel stone a in the wall opening is provided with a sieve made of stainless wire mesh, I = to prevent insects, small animals, leaves, etc. from entering to prevent.
