Изобретение относитс к боргловочному оборудованию даг изготовлени предварительно напр женных железобетонных изделий, в частности к оборудованию дл изготовлени железобетонных шпал. °The invention relates to boring equipment for manufacturing prestressed concrete products, in particular, equipment for manufacturing concrete sleepers. °
Известное устройство даг форловани железобетонных шпал, включающее форму и плиту с фиксирущшли отверсти ми nojj пустотоооразователи, обладает большой трудоемкостью технологического ю процесса изготовлени железобетонных шпал, низким качеством выпускаеглых изделии и небольшим сроком службы съемных плит.The prior art device for forging reinforced concrete sleepers, including a mold and a slab with fixing nojj hollow holes, has a great complexity of the technological process of manufacturing reinforced concrete sleepers, poor quality manufactured products and a short service life of removable plates.
Цель изобретени - утленьшение тру- 15 доемкости технологического процесса и увеличение срока службы штаты.The purpose of the invention is to improve the labor intensity of the technological process and increase the service life of the staff.
Дл этого плита выполнена из упругого 171атериала с запрессовашшгл в нее металлическим сердечником с отверсти лш, 2о снабженным бобышками и фиксаторами.For this, the plate is made of an elastic material with a metal core pressed into it with a hole with a hole 2o, equipped with lugs and retainers.
На фиг.1 показана предлагаема плита , общий вид; на Фиг.2 - то же, разрез по А-А на фиг.1; на фиг.З - металлический сердечник; на Фиг.4 - то же, 25 вид сверхуFigure 1 shows the proposed plate, a general view; figure 2 is the same, the section along aa in figure 1; on fig.Z - metal core; figure 4 - the same, 25 top view
Устройство состоит из штаты I, с . Запрессованным в нее сердечником 2, снабженным бобышками 3, металлических пластин 4 сфиксаторами 5. Корпус I -. зоThe device consists of states I, p. The core 2 pressed in it, supplied with bosses 3, metal plates 4 fixtures 5. Case I -. zo

Устройство работает следующим образом .The device works as follows.
Плита I, выполненна из упругого материала , с металлическжл сердечником 2 крепитс к ctopie 7 крепежныьта детал ми 6. Перед формованием в форме 7с помощью фиксаторов 5 закрепл ютс пустотообразователи . Возникающие при передаче предварительного напр жени арматуры с формы 7 на бетой усили поглощаютс упругой плитой I устройстба. После распалубки плита остаетс в форме 7.The plate I, made of an elastic material, with a metal core 2 is attached to the ctopie 7 with fasteners 6. Before being molded in the form 7 with holders 5, the holders are fixed. The forces arising from the transfer of prestressing from form 7 to beta are absorbed by an elastic plate I device. After stripping, the slab remains in shape 7.
