Description
Изобретение относитс к области строитель ства и может найти применение при изготовлении предварительно напр женных плит, балок, ферм и других элементов покрытий и перекрытий здани .The invention relates to the field of construction and may find application in the manufacture of prestressed slabs, beams, trusses, and other elements of the coatings and floors of the building.
Цель изобретени -- снижение трудоемкости предварительного напр жени .The purpose of the invention is to reduce the labor intensity of prestressing.
На фиг. 1 изображена конструкци устройства; на фиг. 2 - вариант конструк ши устройства; на фиг. 3 - сечение А-А на фиг. 1 и 2; на фиг. 4 - сечение Б-Б на фиг. 1 и 2.FIG. 1 shows the structure of the device; in fig. 2 - a variant of the device design; in fig. 3 is a section A-A in FIG. 1 and 2; in fig. 4 is a section BB in FIG. 1 and 2.
Два несущих жестких элемента 1 и 2 соедин ют распорным устройством с шарнирами 3 и составной зат жкой 4, прикрепленной к крайним выносным упорам 5.The two supporting rigid members 1 and 2 are connected by a spacer with the hinges 3 and the composite fastener 4 attached to the extreme outriggers 5.
Распорное устройство, состоит ил соединенных шарнирами 3 жестких корытообразных элементов 6 с фланцами 7, шарнирно соединенных между собой двухсторонними накладками 8. Элементы 6 упираютс в смежные выносные упоры 5 фланцами 7 и крен тс к ним болтами 9. Нат жение зат жки 4 осуществл ют нат жением распорного устройстваThe spreader device consists of 3 rigid trough-shaped elements 6 connected with hinges with flanges 7 pivotally connected to each other by double-sided lining 8. Elements 6 abut against adjacent outboard supports 5 with flanges 7 and roll them towards them with bolts 9. Tension 4 is tensioned spacer

до соприкосновении зат жки 4 с упорами 5 (фиг. 2) и закреплени ее к ним с помощью анкеров 10 (фиг. 4), заранее прикрепленных к зат жке 4. При повороте элементов 6 распорного устройства по горизонтального положени зат жка 4 с анкерами 10 и разъемной муфтой располагаетс внутри корытообразных элементов 6 по оси упоров 5 и шарниров 3, что обеспечивает совпадение сил обжати от зат жки 4 и от корытообразных элементов 6 на упоры и упрощает как процесс предварительного напр жени , так и разъединение зат жки 4. Затем зат жку разъедин ют и снимают распорное устройст- 5 во. В результате зтого образуютс отдельные предварительно напр женные конструкции.until the fastening 4 is in contact with the stops 5 (Fig. 2) and is fixed to them with the help of anchors 10 (Fig. 4) attached in advance to the fastening 4. When the elements of the spacer 6 are rotated horizontally by tightening 4 with anchors 10 and a detachable sleeve is located inside the trough-shaped elements 6 along the axis of the stops 5 and the hinges 3, which ensures the coincidence of the pressing forces from the tightening 4 and from the trough-shaped elements 6 to the stops and simplifies both the prestressing process and the disconnection of the tightening 4. Then tightening are disconnected and removed Noah ustroyst- 5 in. As a result, separate prestressed structures are formed.
При выполнении торцов корытообразных элементов 6 с закругленными опорными 20 фланцами 7 (фиг. 2) и с эллиптическими отверсти ми жесткие элементы 1 и 2 располагают горизонтально, а предварительное напр жение зат жки 4 осуществл ют только поворотом элементов 6 распорного устройства.When the ends of the trough-shaped elements 6 are made with rounded support 20 flanges 7 (Fig. 2) and with elliptical holes, rigid elements 1 and 2 are arranged horizontally, and the preload tension 4 is carried out only by turning the elements 6 of the spacer.
