Description
кладки lO, пружин II, нижней металлической рамки 12 и верхней металлической рамки 13.masonry lO, springs II, lower metal frame 12 and upper metal frame 13.
Устройство работает следуюпшм образом .The device works as follows.
Форма 3 с насадкой, 4, заполненные бетонйой смесью устанавливаютс в . вакуум-кам е, I, наход щейс на вибростоле 2. Крышкой 5 с нагл ухо. закрепленным к ней штампом 6 закрывают вакуум-, камеру I, путем опускани -на ее кра резиновой прокладкой Ю устройства вертикального пере 1ещенн , состо щего из прорезин« ной ткани 9, металлических рамок 12 и 13. К крышке 5 прорезиненна ткань 9 наглухо крепитс с пс лошью металлической рамки 12. Эта же ткань 9 раст нута пружинами II. Давлением массы крышки 5 и штампа 6 : пружин ы 11 прижимают резиновую прокладку IО к стенкам вакуум-камеры 1 и герметизируют ее. Создание вакуума в вакуум-камере производитс через штуцер 7. Фиксаторы 8 удерживают .штамп 6 и крышку 5 от -пх вертикальных перемещений вниз под действием разности давлений .(вакуума в камере и атмосферного). Вначале бетонна смесь вакуумируетс в процессе ее вибрации. После виброваку умировани смеси освобождаетс фиксатор 8 и штамп 6 с крышкой 5 опускаетс на ее поверхность под действием атмосфергного давлени .Form 3 with a nozzle, 4, filled with a concrete mix is installed in. vacuum chamber, I, located on the vibrating table 2. Cover 5 with impudent ear. fixed to it by a stamp 6, they close the vacuum chamber I, by lowering a rubber gasket 10 of the vertical transfer device, consisting of rubberized fabric 9, metal frames 12 and 13, onto the edge of the device. Rubberized fabric 9 is tightly fastened to the cover 5 ps lyny metal frame 12. The same fabric 9 stretched springs II. The pressure of the mass of the cover 5 and the stamp 6: the springs s 11 press the rubber gasket IO against the walls of the vacuum chamber 1 and seal it. The creation of a vacuum in the vacuum chamber is carried out through the fitting 7. The fixers 8 hold the stamp 6 and the cover 5 from down-down vertical movements under the action of the pressure difference. (Vacuum in the chamber and atmospheric pressure). Initially, the concrete mixture is evacuated during its vibration. After vibrating the mixture, the fixer 8 is released and the stamp 6 with the cover 5 is lowered onto its surface under the influence of atmospheric pressure.

При этом сжимаютс пружины 11 не наруша герметизации вакуум-камеры I После вибровакуумсилевого уплотнени бетонной смеси в вакуум-камеру I посредством крана на штуцере 7 впускаетс атмосферный воздух, снимаетс крышка 5 со штампом 6, извлекаетс форма 3 с насадкой 4 и удал етс из фор мы 3 отформованное изделие. Далее процесс повтор етс .At the same time, the springs 11 are compressed without disturbing the sealing of the vacuum chamber I. After vibrating vacuum compaction of the concrete mix, atmospheric air is injected into the vacuum chamber I by means of a crane at fitting 7, the cover 5 with the die 6 is removed, and the mold 3 is removed 3 molded product. The process then repeats.
