Description

(54) ФОРМА ДЛЯ ИЗГОТОВЛЕНИЯ ЦЕНТРИФУГИРОВАННЫХ ТРУВЧАТЫХ ИЗДЕЛИЙ ИЗ БЕТОННЫХ СМЕСЕЙ(54) FORM FOR MANUFACTURING CENTRIFUGED DIFFERENT PRODUCTS FROM CONCRETE MIXTURES

Изобретение относитс  к производству трубчатых изделий в формах из бетонных смесей центрифугированием , а более конкретно - к устройствам дл5 уплотнени  стыковых разъемов полуформ.The invention relates to the production of tubular products in molds from concrete mixtures by centrifugation, and more specifically to devices for sealing the butt connectors of half-molds.

Известна форма дл  изготовлени  центрифугированных трубчатых изделий из бетонных смесей, содержаща  полуформы с продольными фланцами, между которыми прокладываетс  уплотнительна  резина или другой эластичный материал дл  герметизации стыков ij .The known form for the manufacture of centrifuged tubular concrete products, comprising half-molds with longitudinal flanges, between which sealing rubber or other elastic material is laid for sealing joints ij.

Теплова  обработка таких изделий производитс  непосредственно в формах .Heat treatment of such products is carried out directly in the forms.

Недостатком указанной формы  вл етс  быстрый износ уплотнени , вызванный вли нием высокой температуры и паровоздушной среды во врем  тепловой обработки отформованной трубы. В результате этого материал уплотнени  тер ет эластичность, нарушаетс  герметичность стыкового разъема, снижаетс  качество изделий из-за утечки цементного молока.The disadvantage of this form is the rapid wear of the seal caused by the effect of high temperature and vapor-air medium during the heat treatment of the molded tube. As a result, the compaction material loses its elasticity, the tightness of the butt connector is broken, the quality of the products is reduced due to leakage of the cement milk.

Целью изобретени   вл етс  повышение герметичности и качества формуемых изделий.The aim of the invention is to improve the tightness and quality of molded products.

Указанна  цель достигаетс  тем, что в известной форме, содержащей полуформы с продольными фланцами, контактирующими друг с другом посредством уплотнени , каждое уплотнение выполнено в виде жесткого стержн  с пневмооболочкой, а каждый фланец - с канавкой, в которой размещено уплотнение.This goal is achieved by the fact that, in a known form, comprising half-molds with longitudinal flanges in contact with each other by means of a seal, each seal is made in the form of a rigid rod with a pneumatic shell, and each flange is in a groove in which the seal is placed.

На фиг.1 изображена описываема  форма в разрезе; на фиг.2 - узел 1 фиг.1; на фиг.З - уплотнение.Figure 1 shows the described form in section; figure 2 - node 1 figure 1; on fig.Z - seal.

Форма содержит две полуформы 1 и 2 с продольными фланцами 3 и 4, имеющими канавками 5 и б, между которыми установлено уп.т1отнение. Последнее состоит из пневмооболочки 7, внутри которой находитс  жесткий стержень 8, ограниченный с одной стороны глухим наконечником 9, а с другой - корпусом 10, имеюцим устройство 11 дл  подачи воздуха с обратным клапаном 12 и устройство 13 дл  сброса воздуха с кнопкой 14. Пневмооболочка 7 герметично закреплена с одной стороны на наконечнике 9, а с другой - на корпусе 10.The form contains two half-molds 1 and 2 with longitudinal flanges 3 and 4, having grooves 5 and b, between which there is an upset. The latter consists of a pneumatic shell within which there is a rigid rod 8, bounded on one side by a blind tip 9, and on the other by a housing 10, having an air supply device 11 with a check valve 12 and an air discharge device 13 with a button 14. Pneumatic shell 7 hermetically sealed on the one hand on the tip 9, and on the other - on the housing 10.
