Description

Изобретение относитс  к области изготовлени  бетонных и железобетонных конструкций, а именно к устройствам дл  образовани  каналов в бетонных и железобетонных издели х.The invention relates to the field of concrete and reinforced concrete structures, and specifically to devices for the formation of channels in concrete and reinforced concrete products.

Известен пустотообразователь, корпус которого соединен с валом посредством рычагов tl.A hollow core is known, the housing of which is connected to the shaft by means of levers tl.

Недостатком этого пустотообразовател   вл етс  сложность конструкции и невозможность измен ть диаметр корпуса.The disadvantage of this hollow core is the complexity of the design and the inability to change the diameter of the body.

Наиболее близким по технической сущности  вл етс  пустотообразователь , включающий корпус, выполненный в виде оболочки и прикрепленный; к ее внутренней поверхности в-ал Недостатком этого пустотообразовател   вл етс  невозможность изменени  диаметра в процессе его эксплуатации .The closest in technical essence is a hollow core, comprising a shell made in the form of a shell and attached; to its inner surface in-al The disadvantage of this core-former is the impossibility of changing the diameter during its operation.

Цель изобретени  - расширение технологических возможностей использовани  .пустотообразовател .The purpose of the invention is to expand the technological possibilities of using a formative agent.

Цель достигаетс  тем, что в пустотообразователе , включающем корпус и вал, закрепленный Ма внутренней поверхности корпуса, последний выполнен из упругого листового материала в виде спиральной трубы и снабжен The goal is achieved by the fact that in the hollow core, which includes the body and the shaft fixed to the inner surface of the body, the latter is made of an elastic sheet material in the form of a spiral pipe and is equipped with

стопорным кольцом, установленньюл на наружной поверхности корпуса.snap ring installed on the outer surface of the housing.

На фиг. 1 изображен пустотообразователь , продольное сечение; на фиг.2сечение А-А на фиг.1.FIG. 1 shows a core former, longitudinal section; Fig.2section aa in Fig.1.

Пустотообразователь дл  образовани  каналов разных диаметров в издели х из бетона и железобетона состоит из корпуса 1, к внутренней The hollow core for the formation of channels of different diameters in products made of concrete and reinforced concrete consists of body 1, to the inner

10 поверхности которого жестко прикрюплен вал 2 с воротком 3, на наружной поверхности корпуса установлено стопорное кольцо 4.10 of the surface of which the shaft 2 is rigidly attached with a crank 3, a retaining ring 4 is installed on the outer surface of the housing.

Пустотообразователь работает сле15 дующим образом.The void generator works as follows.

Перед формовкой издели  необходимый диаметр пустотообразовател  достигаетс  путем закручивани  упругого листового корпуса 1 воротком 3 через Before forming the product, the required diameter of the core former is achieved by twisting the elastic sheet body 1 with the driver 3 through

20 вал 2. Затем необходимый диаметр фиксируют стопорным кольцом 4, внутренний диаметр которого равен проектному диаметру канала в изделии. После термообработки издели  при закручивании 20 shaft 2. Then the required diameter is fixed with a retaining ring 4, the inner diameter of which is equal to the design diameter of the channel in the product. After heat treatment of the product when twisting

25 корпуса 1 по спирали валом 2 происходит уменьшение диаметра корпуса, что обеспечивает отрыв его от стенок издели .25 housing 1 in a spiral shaft 2 decreases the diameter of the housing, which ensures separation from the walls of the product.

Изобретение позвол ет примен ть The invention allows the use of

30 пустотообразователь дл  образовани 30 vortex formers

каналов в бетонных издели х различного диаметра, что расшир ет технологические воаможности его использовани .channels in concrete products of different diameters, which expands the technological possibilities of its use.
