Construction of the inspection

inspect projectThe inspection box is made of thick boards 38 mm (1,5 cala). The width of the box is equal to the length of the inspection window used to cover it, and its length is 4…6 window width. The height of the walls depends on the planned cultivation, e.g.. for the production of tomato seedlings you need the height. 40 cm, and for other species it may be less. The north side of the box should be higher than the south by 10 cm, which gives the necessary angle of inclination of the window. The corners of the box are reinforced with posts made of diagonally cut square timber with dimensions of 10×10 cm. The longer sides are connected by crossbars with dimensions of 4×6 cm, on the so-called. dovetail joints, flat, into the edges of the crate walls. Slats are nailed on the south wall, preventing windows from sliding down.
The frame box can be made of bales of pressed straw, which are obtained with the mechanical harvesting of cereals. Need 14 nice 100 x 25 x 35 cm. The gable walls are two bales tightly adjacent to each other with their shorter sides. Side walls are placed perpendicular to them, po 5 bales on each side. The resulting inspect has internal dimensions 130 x 500 cm. It is covered with windows or a frame covered with foil, to make two layers, with empty space inside. Inspect does not need to be covered with heating material. In the fall, it is covered with foil and used to store root vegetables, cabbage and onions.

The most frequently used window is a standard window with dimensions 100 x 150 cm, glazed with 2 thickness glass…3 mm. Size panes 30 x 50 cm are arranged three in three rows, thus the window has two sash bars. The modified window is slightly better, with one astragal and four shafts. While the previous type of window requires puttying, the panes in the modified window can be inserted into the frame and sash bars. The inspection equipment includes ventilators for supporting the windows during airing, rye straw mats with dimensions 120 x 190 cm for covering windows and a paper shade, canvases, reeds or thin slats connected with a string, used to cover the inspection area during strong sunlight.
