Abstract
Изобретение относитс к дорожному строительству, а именно к контролю качества покрытий. Цель изобретени - измерение деформации покрыти под нагрузкой. Устройство содержит корпус с опорой и выемкой дл призмы подпружиненного рычага, который посредством поводка св зан с измерительным приспособлением. Поводок снабжен защитным кожухом, а опора. и выемка расположены на взаимно противоположных сторонах корпуса с возможностью контакта опоры и призмы со стенками скважины в покрытии за счет собственной массы. 2 ил.FIELD OF THE INVENTION The invention relates to road construction, namely to the quality control of coatings. The purpose of the invention is to measure the deformation of the coating under load. The device comprises a housing with a support and a recess for a prism of a spring-loaded lever, which is connected by means of a driver with a measuring device. The leash is equipped with a protective cover and support. and the groove is located on mutually opposite sides of the body with the possibility of contact of the support and the prism with the walls of the well in the coating due to its own weight. 2 Il.

Изобретение относитс к дорожному строительству, а именно к контролю качества покрытий.FIELD OF THE INVENTION The invention relates to road construction, namely to the quality control of coatings.
Цель изобретени - измерение деформации покрыти под нагрузкой.The purpose of the invention is to measure the deformation of the coating under load.
На фиг. 1 показано устройство, разрез; на фиг. 2 - кинематическа схема устройства.FIG. 1 shows the device section; in fig. 2 - kinematic diagram of the device.
Устройство содержит корпус 1 с опорой 2 и, выемкой 3. На корпусе 1 жестко закреплен защитньй кожух 4, внутри которого ра сположен поводок 5 измерительного приспособлени 6. Конец поводка 5 входит в выемку 7 рычага 8, который подпружинен ст жкой 9 и жестко соединен с призмой 10, вход щей .в выемку 3 корпуса 1 . На фиг. 1 позицией 11 показана скважина , позицией 12 - испытуемое покрытие , позицией 13 - предохранителна прокладка с прорезью 14.The device comprises a housing 1 with a support 2 and, a recess 3. On the housing 1, a protective cover 4 is rigidly fixed, inside which the lead 5 of the measuring device 6 is located. The end of the lead 5 enters the notch 7 of the lever 8, which is spring-loaded with with a prism 10, entering into the recess 3 of the housing 1. FIG. 1, position 11 indicates a well, position 12, a test coating, position 13, a safety gasket with a slit 14.
Устройство работает следукицим образом.The device works in the following way.
Корпус 1 с подпружиненным рычагом 8 размещают в скважине 11 испытуемого покрыти 12 с возможностью контакта призмы 10 и опоры 2 с точками А и В стенки скважины 11 за счет собственной массы устройства, дл чего его центр т жести смещен от опоры 2 к измерительному приспособлению 6. На испытуемое покрытие 12 устанавливают предохранительную прокладку 13 с прорезью 14 дл защиного кожуха 4.The housing 1 with the spring-loaded lever 8 is placed in the borehole 11 of the test coating 12 with the possibility of contact of the prism 10 and the support 2 with the points A and B of the borehole wall 11 due to its own weight of the device, for which its center of gravity is shifted from the support 2 to the measuring device 6. A safety gasket 13 with a slit 14 for a protective casing 4 is installed on the test coating 12.
Через предохранительную прокладку 13 на покрытие 12 передают распределенную нагрузку. Деформаци сжати покрыти Лh измен ет положение точки А стенки скважины 11. При этом призма 10 поворачивает рычаг 8 относительно выемки 3 корпуса 1 в точке С. Верхний конец рычага 8 в точке D перемещает поводок 5 на величину а 1, пропорциональную деформации сжати покрыти йЬ, что фиксирует измерительное приспособление 6.Through the safety strip 13 to the floor 12 transfer the distributed load. The compression deformation of the coating Lh changes the position of point A of the borehole wall 11. At the same time, the prism 10 rotates the lever 8 relative to the notch 3 of the housing 1 at point C. The upper end of the lever 8 at point D moves the driver 5 by an amount a 1 proportional to the deformation of the coating y, which fixes the measuring device 6.
