Description

На фиг. 1, 2 и 3 схематического чертежа изображены виды спереди, сбоку и сверху предлагаемого прибора и на фиг. 4-дуга с делени ми.FIG. Figures 1, 2 and 3 of the schematic drawing show front, side and top views of the proposed device, and FIG. 4-arc with divisions.

Прибор состоит из (например чугунной ) линейки 3, двух струбцин 5, шкива, 2, стрелки 4 и дуги 1 с делени ми , насаженной на струбцины. Последние три части прибора могут выполн тьс  из меди. Линейка прикрепл етс  при помощи шурупов 7 к струбцинам , при чем последние зажимным винтом 10 прикрепл ютс  к соответствующей части мостовой фермы (к нижнему по су при измерении проп0ов и к опорной стойке прилзмерении линейных перемещений ферм). В прорези дуги ходит стрелка, наса данна  на общую с блоком ось 8, при чем дл  одновременного вращени  шкива и стрелки, последн  , соединена с ним штифтом 11. Дл  лучшего регулировани  дуги, один конец последней снабжен прорезью .The device consists of (for example, cast-iron) ruler 3, two clamps 5, a pulley, 2, an arrow 4 and a split arc 1, mounted on clamps. The last three parts of the device can be made of copper. The ruler is attached with screws 7 to the clamps, the latter being attached to the corresponding part of the bridge truss by clamping screw 10 (to the bottom of the cube when measuring proposes and to the support stand for measuring the linear displacements of the trusses). An arrow goes in the arc slot, which is pushed onto a common axis with the block 8, with the latter being connected to it with a pin 11 for simultaneous rotation of the pulley and the arrow. For better control of the arc, one end of the latter is provided with a slot.

При помощи перекинутого через блог Tpioca с мертвым грузом, спускаемым на дно реки (при измерении прогиба) и противовеса , стрелка при прогибах фермы вместе с блоком вращаетс , при чем стрелка дает показани  увеличенные в четыре раза. Дл  возможности фиксации максимума и минимума показаний (при отсутствии наблюдател  у прибора) к дуге прикреплены пружинные ползунки 9. Дл  измерений линейных перемещений ферм прибор прикрепл етс  к опорной стойке, а один конец проволоки, перекинутой через шкив, прикрепл етс  к опоре (устою или быку).With Tpioca thrown over the bottom of the river (when measuring deflection) and a counterweight, thrown over the Tpioca blog, the arrow rotates with the block when the trusses deflect, and the arrow gives four times increased readings. To fix the maximum and minimum readings (in the absence of an observer at the device), spring sliders 9 are attached to the arc. For measuring the linear displacements of trusses, the device is attached to the support post, and one end of the wire, thrown over the pulley, is attached to the support (leg or bull) ).
