(5) FORM FOR THE MANUFACTURE OF REINFORCED CONCRETE PRODUCTS

one

The invention relates to the manufacture of building products, in particular to the production of reinforced concrete products in multiplace forms.

A known form-carriage for the manufacture of building products, comprising a pallet, movable longitudinal and end beads, guides for moving these boards and levers mounted on the ends of the boards and connecting them with each other til.

A disadvantage of this device is that only one product can be molded therein and the process of their removal is laborious.

 Also known is a form for the manufacture of reinforced concrete products, containing a pallet with sliding sides, guides placed in opposite sides of the form and a dividing partition installed in them in the form of inserts having cavities in which lifting loops 2 are mounted on the axles.

The disadvantage of the device is that it cannot form products with a complex profile, for example, the profile of unified products of a single catalog.

The purpose of the invention is the expansion of technological capabilities by forming articles of a complex profile.

The goal is achieved by the fact that, in a form for the manufacture of iron 10 concrete products containing a pallet with sliding sides, guides placed in opposite boards of the form and a dividing wall installed in them in the form of contributions 15 necks having cavities in which axes are fitted with lifting loops , each insert is provided with a hinged lever and mounted on it

Claims (2)

20 with a profiler, and the lifting loop has a vertical groove under the axis and a beveled side in contact with the profiler, and on the axis of the lifting loop there are two pairs of articulated between, a tg, with one ends of tg being hinged to the liner, and others the ends are pivotally connected to one of the shoulders of the two shoulders. FIG. 1 shows a device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section of the BBB in FIG. 2; in fig. A - section BB in FIG. 2. The form contains a pallet 1 with movable sides 2 and 3, guides A, placed in opposite sides 2 and 3, and a divided partition installed in them, an effective partition in the form of inserts 5. Each liner has a cavity 6, in which axle 7 is installed lifting loop 8 with a vertical groove 9 and two pairs of tg 10 and 11, one ends of which are hinged by means of an axis 12 connected to a bracket 13 fixed on a liner 5 and others to one of the arms of the double-arm I. The two-arm lever 1 is hinged by an axis 15 mounted on the bracket 16 mounted on the insert 5. On d The arm of the two-arm lever 1C is attached to the profile-former 17 mounted on the pallet 1. In this case, the axis 15 of the rotation of the two-arm lever 1 lies on the straight line Г-Г (Fig. 2) with the protrusion of the profile former T7 and can be shifted from it to the side of the molded product . Lifting loop 8 has a bevelled side 18 in contact with the profile by the former 17 in the working position. The device operates as follows. To bring the mold into position, the beads 2 and 3 are brought together and mounted on their inclined guides A liners 5. Concrete is poured in, compaction and heat treatment are carried out. After shaping and heat treatment, demoulding is performed. The divorce boards 2 and 3 are perpendicular to each other. A hook of a lifting device (not shown) clings to the lifting loop 8 and starts lifting. In this case, the loop 8 rises, the bevelled side 18 24 releases the profile-former 17, the axis 7 slides along the vertical groove 9 until it stops against its wall. After that, the force from the hook is transmitted to the gigs 10 and 11, which, when turned, transfer this force to the double-arm lever N. The latter, turning around its axis 15, releases the profile-former 17 fixed on its shoulder from the finished product. After that, the liner is removed. Due to the location of the RCI 15 on the same line YYY (or offset to the side of the product) with the protrusion of the most distant point of the profile former 17 (Fig. 2), the last exit of the product does not experience sliding friction and does not destroy it, thereby ensuring the safety of the product . Claims The form for the manufacture of reinforced concrete products, containing a pallet with sliding sides, guides, placed in opposite sides of the form and the dividing wall installed in them in the form of inserts having cavities, in which axes have been stopped, which differs from in order to expand the technological capabilities by forming articles of a complex profile, each insert is provided with a shirring attached to it by means of a double-arm and mounted on the base of the profile The body and the lifting loop have a vertical groove under the axis and a beveled side in contact with the profile-former, and on the axis of the lifting loop there are two pairs of hinged and hinged parts, with one ends of the hg hinged to the liner, and the other ends are hinged connected to one of the shoulders of the two shoulders.
