Description
II
Изобретение относитс к строительству , а именно к устройствам дл внутреннего уплотнени бетонных смесей в массивах .The invention relates to the construction, in particular to devices for the internal compaction of concrete mixtures in arrays.
Известен передвижной глубинный виброуплотнитель , содержащий вибраторы и рабочий орган, перемешаемый при помощи тележки внутри уплотн емого массива бетона rijНаиболее близким к изобретению вл етс устройство дл уплотнени бетонной смесп, содержащее возбудители ко- лебаш1Н и рабочий орган в виде жестко закрепленных на раме верхними торцами параллельных пластин 2.Known mobile depth vibratory compactor containing vibrators and a working body mixed with a trolley inside a compacted array of concrete rij. The device for compacting concrete mix containing causative agents of rolls 1H and working body in the form of rigidly fixed to the frame upper ends of parallel plates is the closest to the invention. 2
Непостатком указанных устройств &л етс низкое качество уплотнени вследствие неравномерного воздействи на бетонную смесь, а также высокие энергозатраты .The disadvantage of these devices is the poor quality of compaction due to the uneven effect on the concrete mix, as well as high energy costs.
Целью изобретени вл етс повьзле- ние качества уплотнипн смесп и снижение трудозатрат.The aim of the invention is to improve the quality of compacting and reduce labor costs.
Указанна цель достигаетс тем, что 8 устройстве дл уплотнешш бетонной смеси, содержащем возбудители колебаний и рабочий орган в В1ще жестко закрепленных на раме верхними торцами параллельных пластин, последние попарно соединены с возбудител ми копебашш, размешенными в промежутках между никш.This goal is achieved by the fact that a device for compaction of concrete mixture containing exciters and a working body in B1, rigidly fixed to the frame with upper ends of parallel plates, are connected in pairs with copebash exciters placed between nicks.
На чертеже изображено устройство дл уплотнени бетонной смеси обн вThe drawing shows a device for compacting concrete mix OBN in
В1Щ.В1Щ.
Устройство дл уплотнени бетонной смеси содержит четное число параллельных гибких пластин 1, жестко соединенных своими верхними концами с рамой 2 и попарно св занных с вибровозбудител ми 3, установленными в промежутках между пластинами. В 1сачестве вибровозбудителей используютс , например, магнитострикщюнные вибраторы.The device for compacting the concrete mix contains an even number of parallel flexible plates 1 rigidly connected by their upper ends with frame 2 and connected in pairs with vibration exciters 3 placed between the plates. As a vibration exciter, for example, magnetostrictile vibrators are used.
Дл обеспечени возможности установки рабочего органа и его поворота под juo6uM углом устройство шаргшрии крепитс к мехашюму передвижени к фиксируетс в нужном положении любым известным способом.In order to enable the working device to be installed and rotated at a juo6uM angle, the Shargshria device is fastened to the movement's movement and fixed in the desired position by any known method.
Устройство работает следующим образом .The device works as follows.
При нахождении устройства в восшухе и при йключенных вибраторах 3 параллельные пластины колеблютс в режиме сто чей волны попарно в противофазе. Частота приложени возмущающей силы вибраторов соответствует третьей или более высокой собственной частоте плас тин.When the device is in dry condition and when the vibrators are switched on, the 3 parallel plates oscillate in the standing wave mode in pairs in antiphase. The frequency of application of the disturbing force of the vibrators corresponds to the third or higher natural frequency of the plates.
Приложение возмущаюшей силы вибраторов в пучност х сто чих волн обеспечивает резонансный режим колебаний.The application of the disturbing force of the vibrators in the antinodes of the standing waves provides a resonant mode of oscillation.
При погружении свободных ко1щов параллельных пластин в бето1шую смесь в резулиате поглощени колебательной энергии последней по пластинам начина ют распростран тьс бегущие волны, пеWhen the free sides of the parallel plates are immersed in the concrete mixture in the absorption resultant of the vibrational energy of the latter, traveling waves begin to propagate through the plates;
родпющло энергию от вибратопоп Пгпоимую смесь.Rinse the energy from the vibrotop Ugoy mixture.
