Description

Изобретение относитс к строительной технике, в частности к оборудованию дл изготовлени железобетонных изделий с предварительно напр женной или ненапр женной арматурой, 5The invention relates to construction equipment, in particular, equipment for the manufacture of reinforced concrete products with prestressed or non-stressed reinforcement, 5

Известна форма дл изготовлени железобетонных изделий, включающа торцовые и продольные борта, укрепленные на поддоне, выполненном из двух частей, соединенных между собой при 10 помощи подвижного соединени , к которому прикреплен средний продольный борт, причем подвижное соединение выполнено в виде упругой пластины, жестко прикрепленной к поддону и средне- 5 му продольному борту 13.The known form for the manufacture of concrete products, including end and longitudinal beams, mounted on a pallet made of two parts interconnected with 10 using a movable joint, to which is attached an average longitudinal bead, the movable joint being made in the form of an elastic plate rigidly attached to pallet and medium-longitudinal board 13.

Известна тажке дЛ изготовлени парных железобетонных изделий, включак ца поддон откидные продольные и торцовые борта и средний борт, 20 причем поддон формы выполнен из двух частей, соединенных между собой с помощью шарнирной опоры, к которой прикреплен средний продольный борт, а каждый откидной продольный борт 25 св зан шарнирными т гами с противоположной частью поддона Known for the manufacture of paired reinforced concrete products, including a pallet with folding longitudinal and end boards and a middle board, 20 with the mold tray made of two parts interconnected by means of a hinge support to which the middle longitudinal board is attached, and each folding longitudinal side 25 connected by hinge gami with the opposite part of the pallet

Недостатком этой формы вл етс то, что она не обеспечивает необходимых условий распалубки.30The disadvantage of this form is that it does not provide the necessary conditions for stripping.

Цель изобретени - улучшение условий распалубки.The purpose of the invention is to improve the conditions of stripping.

Эта цель достигаетс тем, что в форме , включающей откидные борта, поддон, состо щий из двух шарнирно соединенных частей с фор юобразу1ощими чейками на каждой, и зачемленный между ними разделитель, части поддона снабжены опорными катками, разделитель выполнен в виде съемного вкладьоаа с двухсторонними выступами, а каждый формообразующий отсек выполнен с пазом в днище дл выступа вкладьвиа .This goal is achieved by the fact that, in a form that includes flaps, a pallet consisting of two pivotally connected parts with shape of cells on each, and why there is a separator between them, the parts of the pallet are provided with support rollers, the separator is made in the form of a removable insert with double projections and each forming compartment is made with a groove in the bottom for the protrusion of the insert.

На фиг. 1 изображена форма дл изготовлени железобетонных изделий, вид сверху; на фиг. 2 - то же, разрез А-А на фиг. 1; на фиг. 3 - то же, в положении распалубки изделий.FIG. Figure 1 shows a form for the manufacture of concrete products, top view; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 - the same, in the position of dismantling products.

Claims

The form contains a pallet 1, made of two parts 2 and 3, connected by an axis 4; the shape of the compartments 5 and b, forming the configuration of individual products 7 and 8 and fixed coaxially on the parts of the pallet 2 and 3, the insert 9 placed between the parts 2 and 3 of the pallet with the support 10, resting on the axis 4, and with two-sided projections 11 and 12, embedded in the bottom 14 and 13 of the compartments 5 and 6, common end boards 15 and 16, connected by hinges 17 and 18 with parts 2 and 3 of the pallet. To secure and tension the reinforcement 19, as well as to fix it on the form after the tension, the end flanges 1 and 16 are equipped with fixed anchors 20, movable anchors 21 and an anvil plate 22. To facilitate movement in the regular way 23, the form is equipped with supporting rollers 24 and 25. For trimming the reinforcement in the beads 15 and 16, as well as in the liner 8, windows 26, 27 and 28 are provided. The manufacture of products in the form is carried out as follows. For manufacturing products with pre-stressed reinforcement, reinforcement rods 20 and 21 are placed in compartments 5 and 6. Rebar 19 is applied. Tension is applied to movable anchors 21 and reinforcement tension is fixed on the mold by moving the stop bar 22 to the left entering it into the grooves of the movable anchors. The tension is then removed, and the mold is fed under the molding. The compartments 5 and 6 are filled with concrete, and then, after steaming, the mold is served under the stripping. The fittings are trimmed through the windows in the sides and in the insert. The sides 15 and 16 are opened, turning them around the hinges 17 and 18. A lift is then brought under the axis 4, and the form is lifted upwards in the direction of the arrow P. At this product 7 and 8, resting against the projections 11 and 12 of the insert 9, they are detached from forming compartments 5 and 6. Then the special cross member is connected with the opening 29 of the insert 9 and the hooks of the cross section take the products together with the insert 9 from the mold. Then the insert 9 is returned to the form. The mold is lowered down and reset. On this cycle of manufacture of products with pre-stressed reinforcement is completed. Claim Form For the manufacture of concrete products, including flaps, a pallet consisting of two hinged parts with formative chambers on each, and a separator clamped between them, in order to improve the conditions of dismantling, the parts of the pallet are equipped with supporting rollers, the separator is made in the form of a removable liner with double-sided protrusions, and each formative compartment is made with a groove in the bottom for the protrusion of the liner.
