Abstract

The invention relates to the manufacture of precast concrete and reinforced concrete products and reduces the laboriousness of changeovers for the manufacture of products of various sizes. This is achieved by the fact that in the multiplace form for the manufacture of products from concrete mixes, the locks are made in the form of eccentric stops 5 with clamps 6 of their position and L-shaped grippers 3 in contact with them fixed respectively to the supporting frame 1 and the extreme flexible elements of pallet 2. 5 silt

This invention relates to the manufacture of precast concrete and reinforced concrete products.

The aim of the invention is to reduce the laboriousness of retooling the mold for the manufacture of products of various sizes.

Figure 1 is a schematic representation of a multi-part form for the manufacture of products from concrete mixtures, top view; figure 2 - section aa in figure 1, in the working position; fig.Z - the same at the time of stripping; Fig. 4 is a view of B in Fig. 2.; Fig. 3, view B in Fig. 3.

The multi-sided form for the manufacture of products from concrete mixes consists of a supporting frame 1, a composite pallet 2 of flexible elements with an i-shaped cross section connected to each other by vertical walls. The pallet is mounted on the frame, and its extreme sections are made with L-shaped grippers 3 and are connected to the frame by means of locks 4. Locks 4 are eccentric stops 5 with clamps 6 of their position, mounted on brackets 7 of the support frame 1. There are also removable stops 8 on the form for tensioned reinforcement 9 and end inserts 10.

Re-equipment of the form and manufacture of products in it is carried out in the following manner.

In frame 1, for the type of product, formative flexible pallet 2, which are secured by means of L-shaped grippers 3 to the frame 1, are fixed to the frame 1, supports 8

for tensioned reinforcement, inserts 10, forming the end part of the product.

Locks work as follows.

The forming flexible pallet 2 is installed with L-shaped grippers 3 in locks 4 and fixed with an eccentric stop 5. The fixation of the eccentric stop is accomplished by moving the retainer 6 to the extreme left position. Dp smen1 forming flexible pallet latch 6 is moved in the opposite direction, freeing from fixation eccentric stop 5.

After laying and tensioning the core reinforcement, the concrete mixture is supplied into the mold, compacted and heat-treated.
