    The invention relates to the manufacture of precast concrete and reinforced concrete products and enables the manufacture of sleepers for turnouts of railway tracks. This is achieved by the fact that in the form for the manufacture of prestressed sleepers made of reinforced concrete, the trays are made up of interchangeable sections in contact with the ends of the sections with grooves forming windows between them. The diaphragms 13 are provided with protrusions 15 arranged in the windows and horizontal parallel bridges 16. The bridges 16 connect the opposite edges of the slots 14 for the passage of the reinforcement. 9 hp ff, 15 ill.

    Claims (7)
    [1]
    Claim ! A mold for the manufacture of prestressed reinforced concrete sleepers, comprising a supporting frame with tensioning devices mounted opposite to the ends, external and intermediate support beams mounted on them with inclined sides, forming parallel molding compartments with pallets, in the windows of which the lower ends of the devices for forming through channels are placed under the bolts for fastening the rail to the sleepers, and transverse partitions in contact with equidistant surfaces with the surfaces of the molding compartments in the form of horizontal traverses with pins mounted at their ends located in the landing holes of the sides, pins interlocked in pairs and connected to each other in each pair by diaphragm spacers having slots for the passage of the product reinforcement, characterized in that, in order to ensure the manufacture of sleepers for turnouts of railway tracks, pallets are made of composite of contacting ends of interchangeable sections with recesses forming windows between them, and diaphragms with horizontal and horizontal protrusions arallelnymi webs joining opposed edges of slots for armature passage.
    [2]
    2. The mold according to claim 1, characterized in that the spacers are made in the form of vertical plates connected to the lower surface of horizontal traverses having sling holes.
    [3]
    3. The form of popp. 1 and 2, it is clear that the pins are arranged vertically and fixed on the lower surface of the horizontal traverses.
    •
    [4]
    4, The form of claims. 2 and 3, it is clear that each horizontal yoke has grips for attaching the diaphragms.
    [5]
    5. The form of claims. 1-4, with the exception that the supporting frame is made with transverse ties in the form of plates connected by means of threaded connections to removable sections of pallets.
    [6]
    6. The mold according to claim 5, characterized in that the interchangeable sections of the pallets are provided with stops in contact with the plates by means of threaded bushes.
    7. The form of claims. 1-6, characterized in that the devices for the formation of through channels for bolts for fastening the rail to the sleepers are made in the form of removable, non-removable threaded dowels made of synthetic material and coupling elements passed through them and connected by threaded connections to removable sections of pallets.
    8. The form of claims. 1-7, characterized in that the inclined sides mounted on the intermediate beam are made elastic.
    9. The form of claims. 1-8, characterized in that the supporting frame is made in the form of longitudinal and transverse crossbars rigidly connected to each other, on which external and intermediate beams made box-shaped are fixed.
    10. The mold according to claim 9, characterized in that the intermediate beam is made with a rectangular cross-section, and the inclined sides mounted on it are connected to each other in the upper part using a horizontal longitudinal plate 1 of the plate.
    11. The mold according to claim 10, with the fact that the lower parts of the inclined sides mounted on the intermediate beam are supported on the latter by means of elastic elements.
