In the upper region 12 and in the region facing the building, the light shaft is designed to be open. The adjoining the upper region 12 lateral surface 18 of the light shaft is semicircular. Thereafter, the light shaft according to the invention has a three-dimensional curvature, which extends in the present example into the lower region 13. The lateral surface 18 is surrounded on three sides by a flange 11, with which the light shaft rests against the building wall. The flange 11 may have a groove 6, which is located in the region of the flange on its side facing the building. This groove 6 is filled with a sealant to prevent ingress of moisture between the flange and the building wall. On the flange 11 hook-shaped fastening means 5 (only one shown) are formed on both sides, with which the light shaft 21 is attached to the building wall. Furthermore, pockets 3 are formed in the flange on both sides, the function of which will be explained later. In the region of the flanges and in the vicinity of the plane of symmetry of the light shaft rows 2 are arranged by bulges having a plurality of teeth which form-fit with indentations, which are arranged on the essay, positively and / or non-positively co-operate, which For example in the Figures 4-6 is shown. At the upper edge of the light shaft is an angular Stiffening 1 arranged to increase the stability of the light shaft, in particular in the upper region,

FIG. 2 shows the attachment 22 according to the invention, which has an upper region 16 and a lower region 15. In the upper area 16 of the tower is designed rectangular, so that rectangular light grid can be placed on him, in the lower part of the essay is designed semicircular, so that it is complementary to the semicircular shape of the upper portion of the light shaft. Right and left, the article on flanges 23, with which the article rests against the building wall and where sealing means can be arranged. With regard to the sealing means and their arrangement, reference is made to the comments on Figure 1.

On the screw with which the fastening means of the attachment is screwed, an L-shaped clamping means 10 is additionally screwed, which does not cover the flange of the attachment prior to the final assembly, as shown in Fig. 5. The person skilled in the art recognizes that the clamping means can also at least partially cover the flange during the construction phase. The vertical forces occurring during the construction phase on the attachment are intercepted by the fastening means and / or introduced by the interlocking teeth of the attachment and the light shaft in the light shaft, possibly also occurring vertical forces are also transmitted from the cam 14 on the light shaft. The screws press the light shaft and the attachment to the building wall. During the construction phase, the excavation pit can already be filled to the lower edge of the attachment. In a later required height adjustment, the screws of the attachment element are released so far that the teeth of the attachment are no longer engaged with the teeth of the light shaft in engagement. The attachment is then in the desired height adjusted and the teeth brought back into engagement. The fastener 19 is now above the screw and now no longer cooperates with the screw. The clamping element 10, which is screwed on in the initial assembly in a vertical position, is turned 90 ° as shown in Fig. 6 and, after re-tightening the screw, applies the required contact pressure to the wall The excavation pit can then be completely filled.
