Description
Количество склеиваемых слоев определяет ширину лестничного марша.The number of layers to be glued determines the width of the flight of stairs.
На чертеже Фиг.1 показан чертеж лестничного марша 1, состоящего из слоев фанеры 2, соединенных между собой слоями эпоксидной смолы 3. Форма слоев фанеры, составляюш;их лестничный марш, определяется из физиологических требований к лестничным маршам 1, в которых удвоенная высота подступенка 4 и ширина проступи 5 в сумме равны среднему шагу человека 0,600,65 м. На практике высота подступенка (Д) обычно выбирается 0,12-0,17 м. Ширина проступи (L) 0,25-0,33 м. Ширина марша (У) определяется числом склеенных слоев фанеры. Соединение марша с поверхностью площадки 6 осуществляется с помощью винтов 7. Некоторые слои фанеры, например, слои 8 могут быть заменены слоями стекла для увеличения стойкости к истиранию.The drawing of Fig. 1 shows a drawing of a flight of stairs 1, consisting of layers of plywood 2, interconnected by layers of epoxy resin 3. The shape of the layers of plywood, compose; their flight of stairs, is determined from the physiological requirements for flights of stairs 1, in which the riser height is 4 and the width of the tread 5 in total is equal to the average step of a person 0.600.65 m. In practice, the height of the riser (D) is usually 0.12-0.17 m. The width of the tread (L) 0.25-0.33 m. The width of the march ( Y) is determined by the number of glued plywood layers. The march is connected to the surface of the pad 6 using screws 7. Some layers of plywood, for example layers 8, can be replaced with layers of glass to increase abrasion resistance.
