Description
в авторском свидетельстве N«49416 описан способ испытани прочности бетона в уже готовых сооружени х, согласно которому о прочности бетона в сооружении возможно судить по силе, потребной дл вырывани предварительно забетонированных в сооружении кернов различной формы . Однако, вырывание кернов, забетонированных вблизи поверхности бетона, не дает возможности судить о прочности бетона в самом массиве последнего. Предлагаемое устройство служит дл устранени указанного недостатка, что достигаетс применением разрезного стержн , отдельные звень которого последовательно св заны между собой отрезками троса и при испытани х подвергаютс последовательному вырыванию из бетона один за другим.The author's certificate No. 49416 describes a method for testing the strength of concrete in ready-made structures, according to which the strength of concrete in a structure can be judged by the force required to tear pre-concreted core structures of various shapes. However, pulling out the cores, concreted near the surface of the concrete, does not make it possible to judge the strength of the concrete in the massif itself. The proposed device serves to eliminate this drawback, which is achieved by using a split rod, the individual links of which are successively interconnected by cable segments and, when tested, are pulled out of the concrete one after the other.
На чертеже схематически изображено предлагаемое устройство.The drawing schematically shows the proposed device.
Устройство состоит из отрезков / труб, соединенных между собой хомутами 2 таким образом, чтобы отрезки труб находились на одной пр мой линии и чюбы между трубами оставались зазоры. В трубы закладываютс отрезки 3 круглого железа , закрывающие зазоры между трубами и частично вход щие в самые трубы. Дл удержани отрезков 3 железа в определенном положении между ними в трубы 1 закладываютс отрезки труб 4 несколько меньшего диаметра, чем отрезки 1. па которые и опираютс отрезки 3 круглого железа. Последние между собой соединены отрезками троса 5, которые, однако, не выбраны втугую, а имеют некоторую слабину.The device consists of lengths / pipes interconnected by clamps 2 so that the lengths of the pipes are on the same straight line and the gaps between the pipes remain. Pipes 3 are inserted into the pipes of round iron, closing the gaps between the pipes and partially entering the pipes themselves. To hold the iron pieces 3 in a certain position between them, the tubes 1 are laid with the segments 4 of a somewhat smaller diameter than the pieces 1. and the segments 3 of the round iron are supported. The latter are interconnected by segments of the cable 5, which, however, are not chosen tightly, but have some slack.
Указанное приспособление устанавливаетс в опалубке до бетонировки сооружени с таким расчетом, чтобы верхний конец отрезков 1, снабженный фланцем 7, выходил на поверхность сооружени . При бетонировке бетон придет в соприкосновение с трубами и отрезками 5, наход щимис в зазорах между отрезками /.The said fixture is installed in the formwork prior to the concreting of the structure so that the upper end of the segments 1, equipped with a flange 7, extends to the surface of the structure. During concreting, the concrete will come in contact with the pipes and segments 5, which are in the gaps between the segments.
При испытании производитс выдергивание стержней 3 из бетона, т. е. определ етс сцепление бетона с железом, которое пропорционально механическим свойствам бетона.During the test, the rods 3 are pulled out of concrete, i.e. the adhesion of concrete to iron is determined, which is proportional to the mechanical properties of the concrete.
Предмет изобретени . 1. Устройство дл определени прочности бетона в сооружени х, служащее дл осуществлени способа по авторскому свидетельству № 49416, отличающеес тем, что, с целью определени прочности бетона не только вблизи поверхности, но к в глубине массива сооружени , вырываемые из последнего по основному авторскому свидетельству стержни выполнены разрезными в виде отдельных отрезков, св занных между собой отрезками троса.The subject matter of the invention. 1. A device for determining the strength of concrete in structures, which serves to carry out the method according to the author's certificate No. 49416, characterized in that, in order to determine the strength of concrete, not only near the surface, but to deep in the massif of the structure, pulled out of the latter according to the main author's certificate the rods are cut in the form of individual segments, connected by cable segments.
2. В устройстве по п. 1 применение св занных между собой хомутами 2 отрезков / труб, между концами которых расположены отрезки 3 вырываемого из массива бетона разрезного стержн .2. In the device according to claim 1, use of 2 segments / pipes connected with clamps, between the ends of which are located segments 3 of a split rod pulled out of the concrete mass.
