2. The installation according to claim 1, characterized in that it is made sectional with intermediate spacer blocks, and the separating diaphragms are common to all sections,

3. Installation on PP. 1 and 2, characterized in that, with

1. The invention relates to the construction materials industry, mainly to installations for the manufacture of flat slabs on a cement in a binder.

The purpose of the invention is to increase the productivity of the plant and the manufacture of prestressed products.

FIG. I depicts a cassette box, a top view before concrete slab; in fig. 2 the same, after concreting the slabs; in fig. 3 shows section A-A in FIG. one; FIG. 4, a three-section cassette installation with intermediate spacer blocks, top view; Fig. 5 shows a cassette installation after stripping with prestressed reinforcement, the cross section; Fig 6 is the same in the working position.

The cassette installation consists of a base 1, rigid end and side longitudinal walls 2 and 3, separation diaphragms 4, anchor blocks 5, intermediate spacer blocks 6 and an assembly and disassembly mechanism 7.

Rigid end walls 2 are mounted on the base 1 between the separation diaphragms.4 and are attached to the guide beams 8 of the transverse displacements.

The side longitudinal walls 3 and one of the anchor blocks 5 have stops 9 for power devices, for example, jacks 0 of the assembly and disassembly mechanism 7, designed to move them. Separating diaphragms 4 are fixed to the anchor blocks 5 using plates P, bolts 12 and anchors 13. Heating elec- ters are placed between the separating diaphragms 4

In order to manufacture prestressed products, the end walls are made up of two parts with grooves along the connector line for tensioned reinforcement, both parts being attached in pairs to the separating diaphragms constituting the molding section.

ment 14 for heat treatment of products 15 with prestressed reinforcement 16.

The device works as follows.

The surfaces of the separation diaphragms 4, the end walls 2 are greased. The separation diaphragms 4 are tensioned by the movement of the anchor blocks 5 using jacks 10 after the tension of the position of the anchor blocks 5 is fixed to the fastening devices. Then the rigid side longitudinal walls 3 are moved with the help of power devices, while the end walls 2 and the separation diaphragms 4 tightly press one other. The separating diaphragms 4 are displaced in the plan, forming on the edges with the end walls 2 tilt angles, which are intended to ensure good conditions for the removal of slabs. The position of the lateral longitudinal walls 3 is also fixed fixing devices.

After the mold is filled with concrete, vibrated, and the required strength is reached, the form is removed.

Stripping is carried out in reverse order. The locking parts are removed. With the help of jacks 10, rigid lateral longitudinal walls 3 are pulled away. Since the separating diaphragms 4 are strained and there are fracture angles of the surface, they tend to straighten and follow the moving lateral piercing walls 3. At the same time, the separating diaphragms 4 open from 15, Removing the pre-stress of the isolating diaphragms

4 is generally not performed by moving the support block 5.

When performing a cassette installation, multisectional separation diaphragms A are installed to the full length of all sections. Between the sections, intermediate spacer blocks 6 are installed.

Item 15 installs rigid end walls 2, which consist of two parts with grooves along the connector line for tensioned reinforcement 16, so that after pressing one to the other, openings are formed for the passage of tensioned reinforcement 16.

After fixing the stripping of the product 15 is removed and the work cycle is completed.
