Изобретение относитс к промышленности строительных материалов, оно может быть использовано при изготовлении изделий из бетона и железобетона на заводах стройиндустрии.The invention relates to the building materials industry, it can be used in the manufacture of concrete and reinforced concrete products in the construction industry plants.
Известен способ динамического уплотнени бетонной смеси при формовании изделий путем одновременного воздействи ударно-затухающих силовых импульсов и вибрации 1.There is a method of dynamically compacting a concrete mix during the molding of products by the simultaneous action of shock-damped power pulses and vibration 1.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс способ, включающий укладку бетонной смеси в форму и ударные воздействи на нее с частотой 3-5 гц до полного уплотнени 2 ,The closest to the proposed technical essence and the achieved result is a method that includes laying the concrete mixture into the mold and impacting it with a frequency of 3-5 Hz until complete compaction 2,
Однако при частоте 3-5 гц не происходит эффективного разжижени бетонной смеси.However, at a frequency of 3-5 Hz, the concrete mixture does not effectively dilute.
Целью изобретени вл етс интенсификаци процесса формовани бетонной смеси.The aim of the invention is to intensify the process of forming a concrete mix.
Это достигаетс за счет того, что в способе формовани бетонных изделий на ударной установке, включающем укладку бетонной сме,си в форму и ударные воздействи на нее с частотой 3-5 ГЦ до полного уплотнени ,бетонную смесь предварительно подвергают ударному воздействию с частотой 6-13 ГЦ в течение 2-3 мин.This is achieved due to the fact that in the method of molding concrete products on a drum set, which includes laying concrete mix, squeezing into a mold and impacting it with a frequency of 3-5 Hz until fully compacted, the concrete mix is preliminarily subjected to shock impact with a frequency of 6-13 HZ within 2-3 min.
Пример. В установленную на ударном столе форму укладывают бетонную смесь с жесткостью 60-90 с и подвергают ударному воздействию при частоте ударов 12 гц в течение 2 мин. После этого бетонную смесь Example. A concrete mix with a rigidity of 60-90 s is placed into a form installed on the impact table and subjected to a shock effect at a shock frequency of 12 Hz for 2 minutes. After this concrete mix
0 уплотн ют при частоте ударов 4 гц до полного уплотнени .0 compacted at a shock frequency of 4 Hz to complete compaction.
Данный способ позвол ет повысить качество изделий при пониженных трудовых и энергетических затратах за This method allows to improve the quality of products with reduced labor and energy costs for
5 счет сокращени времени формовани жестких бетонных смесей при изготовлении изделий сложной конфигурации.5 by shortening the molding time of hard concrete mixtures in the manufacture of products of complex configuration.
