Method for preparation of woody material samples, preferably shoots of woody plants, for strength tests, in particular for shear strength test and the device for execution of this method

摘要

in the preparation of samples of tree, especially of woody plants to stress tests, in particular to test for shear strength should be a maximum of 10 cm in length, momentum and do the following: face m diameter of momentum and put him in the samples, tighten the screws holding the sample (17) in such a waythat momentum not przekru0119cau0142 and not pushed, then set the dimension scale, defining it by placing a resistor adjusted by screws the knives and depth of cuts (11) to perform an incision on the right side, should be placed in the sample holder glimmer jne location left, with the sample holder is adjusted by adjusting bolts (8), a sample holdersubsequently, by regulating the screw less (10) move forward rise less, until the impact in the resistors, and then perform an incision using knives (4), after the incisions withdraw element also through regulating the bolts (10), and less stu0119pnie by right turning knives (4) to make knives (4) and marked the location,which will be later cut off part of momentum, and to perform an incision on the left side, should proceed similarly as in the performance of incision on the right side, with the difference that the element should be set in the extreme position.the object of the application is also a device for the preparation of samples of tree, especially of woody plants to stress tests.
