Description

The invention relates to the production of precast concrete and reinforced concrete.

The aim of the invention is to reduce the complexity of manufacturing products.

FIG. 1 shows schematically a mold for the manufacture of ribbed products from concrete mixtures, a plan view; in fig. 2 shows section A-A in FIG. 1 (option to install the liner on the coil springs); in fig. 3 shows section A-A in FIG. 1 (option to install the liner on the leaf springs); in fig. 4 is a view B in FIG. 2

The form for the manufacture of ribbed concrete mixtures consists of a pallet 1 with a fixed caisson 2 and elastic end boards 3 rigidly attached to the pallet 1 forming the edges of the product, movable longitudinal sides 4 and lock locks 5 on the ends of the adjacent sides 3 and 4.

In the lower part of the shaping walls 6 and 7, respectively, of the caisson 2 and the elastic end boards 3, shaped grooves are made in which the liners 8 which are spring-loaded in the vertical direction are installed to form through-grooves on the edges of the product. Wedge-shaped copiers 9 are fixed at the ends of elastic end boards 3, and stops 10 are attached to adjacent longitudinal sides 4, between which, with closed boards, there is a guaranteed clearance 5 The height of the copier 9's slope h and its height relative to the pallet are set in such a way that opening of elastic end boards 3 occurs only within the elastic deformations of the material of its wall 7.

The liner 8 can be mounted on the brackets 11 and 12 of the pallet 1 by means of cylindrical compression springs 13 or by means of a plate spring 14- fixed rigidly on the bracket 15 of the pallet 1, and pressed against the walls of the shaped groove of the shaping walls 6 and 7. The manufacture of ribbed concrete products works as follows.

After forming and heat treatment, the product is dismantled, the longitudinal edges 4 are opened. At the time of tearing the longitudinal edges 4 from the spun-out product due to the clearance ff, the copiers 9 and the stops 10 initially do not contact each other and only after the separation of the longitudinal edges 4 from the product and the choice of the gap S, the stops 10 are in contact with the copiers 9 with the further opening of the longitudinal sides 4, and due to the wedge-shaped shape of the copiers 9, the elastic face edges 3 are detached from the product and opened by a predetermined value. When the elastic end beads 3 are opened, the latter with the shaping wall 7 acts on the forming surface of the inserts 8 which mate with them, which rotate together with the elastic end flanges 3 to position B and detach from the spun-out product. At the end of the opening of the longitudinal sides 4, the horizontal sections 16 of the stops 10 are in contact with the horizontal sections 17 of the copiers 9 and hold the elastic face boards 3 in the open position.

After removing the product from the mold, the longitudinal beads 4 are closed, and after releasing the contact of the portions 16 and 17, the elastic front beads 3 under the action of the elastic properties of their walls 7 return to their original position, and the spring-loaded inserts 8 as the elastic end beads 3 close also return to their original position position.
