Прибор относитс к устройствам дл испытани бетона в конструкци х без их разрушени и может быть использован в строительстве и промышленности строительных материалов..The device relates to devices for testing concrete in structures without destroying them and can be used in the construction and building materials industry.
Известен прибор ударного действи дл определени прочности бетонов, включающий упорную гильзу, в которой установлен подпружиненный корпус с крышкой и с подпружиненным ударником внутри, установленным на уширении корпуса, в котором выполнена продольна щель под закрепленное на упорной гильзе спусковое устройство 1.A percussion device for determining the strength of concrete is known, which includes a stop sleeve in which a spring-loaded housing with a lid and a spring-loaded hammer inside, mounted on the expansion of the housing, is installed, in which a longitudinal slit is made for the trigger device fixed on the stop sleeve.
Недостатком известного прибора вл етс сложность конструкции, а также Трудоемкость взвода ударной части.The disadvantage of the known device is the complexity of the design, as well as the complexity of the strike platoon.
Наиболее близким к изобретению вл етс прибор ударного действи дл определени прочности бетонов, содержащий упорную гильзу, размещенные в ней подпружиненный корпус с крышкой и ударник с выточкой , и спусковое приспособление в виде подпружииенной планки, размещенной в проушине упорной гильзы 2.The closest to the invention is a percussion device for determining the strength of concrete, containing a stop sleeve, a spring-loaded case with a lid and a drummer with a recess, and a trigger device in the form of a spring-loaded strap, placed in the eye of the stop sleeve 2.
Недостатком его вл етс наличие только одного значени энергии удара, что не позвол ет производить испытани в интервале от марки бетона М10 до 800 без замены диаметра индентора или пружины. ,The disadvantage of it is the presence of only one value of the impact energy, which does not allow testing in the range from the concrete grade M10 to 800 without replacing the diameter of the indenter or spring. ,
5 Цель изобретени - повышение точности испытаний.5 The purpose of the invention is to improve the accuracy of testing.
Достигаетс цель тем, что прибор ударного действи дл определени прочности бетонов, содержащий упорную гильзу, размещенные в ней подпружиненный корпусThe goal is achieved by the fact that the percussion device for determining the strength of concrete containing a resistant sleeve, placed in it a spring-loaded body
10 с крыщкой и ударник с выточкой, и спусковое приспособление в виде подпружиненной планки, размещенной в проущине упорной гильзы, снабжен упорным конусом и фиксаторами, причем ударник выполнен с10 with a lid and a drummer with a groove, and the trigger device in the form of a spring-loaded strip placed in the pro-wall of the thrust sleeve, is provided with a stop cone and retainers, and the drummer is made with
,5 дополнительными кольцевыми выточками, а корпус- с уступом, взаимодействующим с фиксаторами., 5 additional annular recesses, and the body with a shoulder interacting with the latches.
На фиг. I изображен предложенный прибор в разрезе; на фиг. 2 - фиксаторы в 20 разрезе.FIG. I shows the proposed device in section; in fig. 2 - clamps in 20 section.
Прибор имеет три энергии удара: основна и две дополнительных (2 фиксатора).The device has three impact energies: the main and two additional (2 clamps).
