Description

В авторском свидетельстве ° 51829, 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, ° 51829, 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 strength required to pull 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 чтобы 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 7 закладываютс  отрезки труб 4 несколько меньщего диаметра, чем отрезки /. на которые и опираютс  отрезки 5 круглого железа. Последние между собой соединены отрезками троса 5,. которые, однако, не выбраны втугую, а имеют некоторую слабину.The device consists of pieces / pipes interconnected by clamps 2 so that the pieces of pipes are on the same straight line and that gaps remain between the pipes. 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 7 are laid with the lengths of the tubes 4 of a somewhat smaller diameter than the segments /. on which the circular iron pieces 5 are supported. The latter are interconnected segments of the cable 5 ,. which, however, are not chosen vint, but have some slack.

Указанное приспособление устанавливаетс  в опалубке до бетонировки сооружени  с таким расчетом, чтобы верхний конец отрезков /, снабженный фланцем 7, выходил на поверхность сооружени . При бетонировке бетон придет в соприкосновение с трубками 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 / provided with the flange 7 extends to the surface of the structure. During concreting, the concrete will come in contact with the tubes 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 testing, the rods 3 are made of concrete, i.e., the adhesion of concrete to iron is determined, which is proportional to the mechanical properties of the concrete.
