Description

. Изобретение касаетс  приборов дл  определени  изгибающих моментов, опорных усилий и стрел прогиба неразрезнь1х балок, с- использованием пружинных динамометров и индикаторов, пружинной нажимной скобы, перестав ных опор и масштабной линейки. В пред . The invention relates to instruments for determining bending moments, supporting forces and deflection arrows of uncut beams, with the use of spring dynamometers and indicators, a spring clamp bracket, moving supports and a scale bar. In pre

л гаемом приборе применены трубчатые опоры,, через полость которых свобо;з;но проходит стержень, соедин ющий .указатель динамометра с:опорной частью испьттуемой балки;На чертенке фиг. 1 изображает продольный разрез прибора; фиг. 2-поперечный разрез его. - . f :A tube device, through which a cavity is free, is applied to the instrument, but a rod passes through which connects the dynamometer pointer to: the supporting part of the beam being drawn; 1 shows a longitudinal section of the device; FIG. 2 is a cross-section of it. -. f:

Прибор (фиг. 1) монтирован на станине , состо щий из основани  5, стойки 8,The device (Fig. 1) is mounted on a frame consisting of a base 5, a pillar 8,

The base 5 is fastened to the screws in the wooden board 6, into which and below are screwed into the four screws holding the rubber pads to protect them from jolts. Along the base

Он состоит из: головки, .ввинчивающейс  в седло 14 посредством резьбы Бинта большого шага. Резьба винта pacc.iHTaHa так, что при каждом полном повороте головки производитс  .давление силой в 5 , тонн; всего можно сделать два поворота, при чем доли поворотов винта отсчитываютс  при ПО station 5, move on the rack, with the help of gear 16, Poduzhnye support 4 and 7. On the rails 2 of the frame you can move the load-dvilkkok 1, transmitting differential pressure. It consists of: a head that is screwed into the saddle 14 by means of a large stride thread. The screw thread is pacc.iHTaHa so that each full turn of the head produces a pressure of 5 tons; a total of two rotations can be made, at which fractions of rotations of the screw are counted with software

Test beam 3 consists of two talnyh bands (Fig. 2), from which, for one band, the moments are calculated for. Delki, and on the other-Q. .

На одной из балок нанесены делени , характеризующие пролеты балки и ее консоли. Если балка разных моментов инерции, то ее привод т к одинаковым моментам инерции, увеличива  величину , пролета соответственно формуле-Мерш On one of the beams there are divisions that characterize the spans of the beam and its console. If the beam is of different moments of inertia, then it leads to the same moments of inertia, increasing the value of the span, according to the Mersch formula
