Description

I   I

Изобретение относитс  к исследованию т строительных материалов.,..Известен способ определени  прочности бетона в головных бетонных и железобетонных юде и х, включающий нанесение удара молотком со сферическим индектором, и замер величины образовавшейс  лунки, по которой суд т о прочности бетона 1.The invention relates to the study of construction materials. .. A method is known for determining the strength of concrete in concrete and reinforced concrete headworks and x, including striking a hammer with a spherical indicator, and measuring the value of the resulting hole, which is used to judge the strength of concrete 1.

Недостаток способа состоит в том, что величина лунки зависит не только, от прочности бетона, но и от скорости молотка перед ударом, котора  не учитываетс .;The disadvantage of the method is that the size of the hole depends not only on the strength of the concrete, but also on the speed of the hammer before the impact, which is not taken into account;

Наиболее близок к описываемому изобретению способ определени  прочности бетона, включающий приложение к поверхности бетона ударной нагрузки посредством индентора и измерение скорости индентора 2.,Closest to the described invention is a method for determining the strength of concrete, which involves applying a shock load to the concrete surface by means of an indenter and measuring the speed of the indenter 2.,

Недостатком способа  вл етс  необходимость замера диаметра лунки.The disadvantage of the method is the necessity of measuring the diameter of the well.

Цель изобретени  - повышение точности ,, определени  прочности бетона.The purpose of the invention is to improve the accuracy, to determine the strength of concrete.

Цель достигаетс  тем, что в способе определени  прочности бетона, включающем прийОжениё к поверхности бетона ударной п грузкн посредством индентора и измерение скорости индентора, дололингель о измер ют врем  длитчгль ости удара и путем сравнени  скорости ййй(ентдр:а Г В1)еменй длительности удара исследуемого и эталонного бетона суд т 9 прочности исследуемого бетон. На фиг. 1 изобр ажено устройство, по сй ющее осуществление npieHJiaraeMoro способа, обшрий вид; на фиг. 2 - кривые зависимости BpeivieHH йп ит льнбс1и удара от скорЬсти индентора.The goal is achieved by the fact that in the method of determining the strength of concrete, which involves hitting the concrete surface with a shock by means of an indenter and measuring the speed of the indenter, the dololingel measures the duration of impact and comparing the velocity of the impact (measure: and reference concrete trial t 9 the strength of the investigated concrete. FIG. 1 shows a device illustrating the implementation of the npieHJiaraeMoro method, a wide view; in fig. 2 - curves of BpeivieHH yp it lnbs1i blow from the speed of the indenter.

Устройство вкл ючаёт корпус 1 молотка, йндентор 2, руко тку 3, приспособление дл  определени  скорости; содержащее подвижный контакт 4, укрегшенный на ползуне 5, вьшо ненном в виде стержни, расположенного в направлшощшс 6, закрегтентк на корпусе. Относительно корпуса неподвижно укреплены два контакта 7.The device includes a hammer body 1, an indentor 2, a handle 3, a device for determining the speed; containing a movable contact 4, ukreggshenny on the slider 5, mounted in the form of rods located in the direction of the pad 6, located on the housing. Regarding the hull two contacts are fixedly fixed 7.

Кроме того, устройство содержит приспособленне дш определени  времени длительности удара, содержащее инерционный контакт 8, прикрепленный при. помощи стержн In addition, the device contains a device for determining the duration of the impact, containing an inertial contact 8 attached at. relief rod
