Description
Изобретение касаетс прибора дл измерени деформаций и внутренних напр жений в древесине при ее сушке. Известные приборы замер ют данные, относ щиес к определенному моменту, и не позвол ют .8 полной мере устаноЕиггь и изучить развитие деформаций и напр н ени1 1 в древесине, ио мере ее высыхани .This invention relates to a device for measuring deformations and internal stresses in wood when it is dried. The known instruments measure the data related to a certain moment and do not allow .8 to fully establish the pressure and to study the development of deformations and intensity 1 1 in wood, and to the extent of its drying.
Предлагаемый прибор упрощает измерение развити внутренних напр жений в образцах высушиваемой древесины, что поможет изучению этих влений.The proposed device simplifies the measurement of the development of internal stresses in samples of dried wood, which will help to study these phenomena.
Прибор выполнен в виде установленных на станине двух вертикальных поворотных стержней, снабженных в верхней части индикатором (мёссурой) дл измерени линейных деформаций и двух горизонтальных щтанг, причем одна из горизонтальных щтанг соедин ет вертикальмые стержни BKIHJS, а друга выполнена съемной и укреплена между вертикальными стержн ми над образцом древесины, удерлчиваемым между этими стержн ми посредством захватов.The device is designed as two vertical rotary rods installed on the frame, fitted in the upper part with an indicator (Mussura) for measuring linear deformations and two horizontal shthangs, one of the horizontal shthang connecting vertical rods BKIHJS, and the other made removable and fixed between vertical rods over a wood sample held between these rods by means of grippers.
На чертеже изображена принципиальна схема работы прибора прч 1:1;1сде,лои11 ; дсфсрмаций в процессе сушки.The drawing shows a schematic diagram of the operation of the device prl 1: 1; 1sde, loi11; Drying process.
Образец древесины / закрепл ют межд двум вертикальными щтангами 2, нижние концы которых жестко закреплены и рассто ние И между ними сохран етс посто нным. Верхние концы штанг имеют возможность поворачиватьс на некоторый угол « около точек А п Л, пр, удлинении или укорочении образца. Зиа соотношеии. илеч AD и ЛВ и замер индикатором величину отклонени верхних концов штанг, л подоби треугольн ков огфедел к1Т деформации образца.The wood sample / is fixed between two vertical legs 2, the lower ends of which are rigidly fixed and the distance And between them remains constant. The upper ends of the rods have the ability to rotate at a certain angle about the points A p L, pr, lengthening or shortening the sample. Zia Ratio. The heals are AD and LV, and the indicator measures the amount of deflection of the upper ends of the rods, likening triangles of specimen deformation.
Предмет изобретени Subject invention
Прибор дл измерени деформаций и внутренних напр жений в древесине , которые возникают, например, в процессе сушки ее в жидкг.х :;ли газообразных средах, от л п ч а го ши и с тем. что, с це.чью ynjxnueНИИ измерений внутренних напр жений в образце древесины, прибор выполнен в виде установленных на станине дв)х вертикальных поворотных стержней, верхние концы которых соединены съемными т гами с индикатором, и двух горизонтальных штанг, причем к одной из штанг вертикальные стержни присоединены внизу, а друга штанга выполнена съемной и укреплена между стержн ми над образцом древесины, удерживаемым между стержн ми посредством захватов.A device for measuring deformations and internal stresses in wood, which arise, for example, in the process of drying it in liquids: • whether gaseous media, from a PC, and so on. that, with the purpose of measuring internal stresses in a wood sample, the device is designed as two vertical pivot rods installed on a frame, the upper ends of which are connected by detachable rods with an indicator, and two horizontal rods, one of which is vertical the rods are attached at the bottom, and the other rod is made removable and strengthened between rods above a wood sample held between rods by means of clamps.
