(54) MULTI-PLACE FORM FOR THE MANUFACTURE OF REINFORCED CONCRETE PRODUCTS

The invention relates to the industrial production of precast concrete and reinforced concrete products in factories, landfills and construction industry sites. The known form for the manufacture of reinforced concrete products, including a multi-seat cassette mounted on a horizontally aligned support with a flexible sheet-goddon, outer and middle partition walls and the bead connecting elements combined with the cassette 1. The disadvantage of this form-chisel is the need to perform labor-intensive separation operations beads from the cassette manually. Also known is the form for the manufacture of reinforced concrete products, containing a flexible pallet with outer and inner longitudinal sides, end boards connected by removable rods hinged to the outer longitudinal sides 2. A disadvantage of the known form is the high labor intensity of dismantling products without slinging loops. The purpose of the invention is to reduce the labor intensity of dismantling products. The goal is achieved by the fact that in the form containing flexible pogdon with external and internal longitudinal sides, transverse boards connected by removable strings, pivotally connected to external longitudinal sides, removable rods are made with bearing pads and connected to external longitudinal sides by means of biaxial levers. In addition, the form is equipped with protective pads rigidly mounted on the outer longitudinal sides. FIG. 1 shows the multi-seat form in the plan; in fig. 2 is a transverse section of the TT nafig. one; in fig. 3 - form at the time of stripping nzdely. The form shown in the drawings includes multi-cassettes with a flexible base 1, middle and outer edges 2 mounted on aligned supports 3, which are fastened with end flanges 5 by means of power brackets 4. Boards 5 are screwed together by means of screw connections 6, which are mounted pivoting stops 8, their lower parts are made with support sites 9.

Between the outer sides of the 2 cassettes and the supporting rods 7. The pine levers 10 are placed by the dvz;

To the outer sides of the 2 cassettes there are {{) clamps 12, covering the two-axle levers 10, hinges 11, pivot-stops 8 with supporting pads 9 and not carrying the bar 7 from clogging them with concrete.

For the removal of formed products without lifting loops, stand 13 is used with convex jacking supports 14, the height of which provides lifting and unfolding of cassettes with disassembled products above the top of the sides of the form 5.

In the assembled form, the beads 5 tightly abut the torps of the pallets 1 and the beads of the 2 cassettes.

The removal and removal of products from the mold is carried out as follows.

By rotating the supporting rods 7, the tightening of the screw joints 6 in the beads 5, the front beams 5 from the flexible bottom and the longitudinal sides 2 of the outer cassettes are loosened. Then the shape of the line and the crane are mounted on the wall 13, resting its cassettes with arms on the convex supports 14. At the same time, due to the weight of the cassettes with products, they rise upward, extend over the sides 5 and unbend on the convex supports 14 of the stand 13.

The outer longitudinal beads 2, connected by biaxial levers 10 to the rods 7, separating the lottery from the extreme products in the cassettes, the products are completely separated from the forming surfaces and, manually or with a special device, are disassembled. . Assemble the form, remove it with a crane from the stand 13 and install 9 pivot stops 8 on the leveled base with support sites. ten

Claims (2)

1. Multiple form for manufacturing (1) reinforced concrete products, containing a flexible 15 pallets with outer and inner longitudinal sides, transversal boards, connected by removable rods, hinged to the outer longitudinal sides, which is, in order to reduce labor intensity the process of stripping products without building loops, removable rods are fitted with supporting platforms and connected to the outer longitudinal sides by means of biaxial levers. 2. The form according to claim 1, is different because it is equipped with protective nakl Kami, rigidly fixed on the outer longitudinal sides.
