Disadvantages: insufficiently high installation performance.

As the closest analogue, the known installation for forming volumetric blocks in the description of the invention to patent No. 2106962, IPC B28B 7/22, from 04/14/1993, publ. 03/20/1998, including a core with rotary longitudinal and transverse shields, tilters, assembly, molding, heat treatment and formwork posts. The device is equipped with an additional core with rotary longitudinal and transverse shields and an additional post of heat treatment. The cores are made with supports for the boards and are mounted with the possibility of reciprocating movement along the installation axis from the molding station to the heat treatment stations and vice versa, and the heat treatment stations are located on opposite sides with respect to the tilters.

Disadvantages: insufficiently high performance.

The prototype has a large number of details for the preparation and implementation of the molding process. The device consists of assembly, molding, heat treatment and stripping posts, two movable cores and an additional one. The cores have supports for shields and are equipped with wheels, with the help of which they move along the rail track. For the implementation of the process requires a lot of time to engage all structural elements, resulting in a large amount of work. The assembly and disassembly of the mold is carried out using manual labor, and not mechanically, which reduces productivity.

Technical result: increased productivity of the installation. The technical result in the installation for the manufacture of volumetric blocks is achieved due to the fact that it includes a frame with a flat platform, a pair of longitudinal, end and balcony panels, a skirt and a core, while the rails are fixed to the frame, the skirt, which is the basis of the future block room, the core of the vertical direction, and the core of the vertical direction is equipped with hydraulic jacks for lifting and lowering, and pairs of longitudinal, end and balcony panels with hydraulic jacks, vibrators, a locking system for fixing end shield with longitudinal shields, the movement of which is carried out with the help of hydraulic jacks, with carriages moving on rails, while inside the cavity of each specified shield and core there is a steam shirt that provides heating and a set of strength of the product.

Compared with the prototype, the inventive device does not require a large amount of work - removal of the shields from the supports and translating them into a horizontal position is carried out semi-automatically.

The inventive device provides the exclusion of physical labor mechanical actions. The movement of the sides in the horizontal direction from the core is carried out using hydraulic jacks along the rail track of the frame using carriages that are attached to each of the shields. The core is lifted in the vertical direction as high as possible using hydraulic jacks lifting and lowering. Exposure of the shields close to the skirt is carried out using hydraulic jacks of the shields, which are fixed by the rod on the shields and the tail to the frame rack. Using hydraulic jacks, a locking system is fixed with a locking system. The concrete mixture located in the formed molding cavity is compacted with shield vibrators and depth vibrators, the product is heated using steam shirts, the internal cavities of the core and side panels, into which steam is supplied with a temperature of 100-115 degrees Celsius for a period of time from 5 to 10 hours depending on the concrete mix. After heat treatment, the locking system is opened using hydraulic jacks. Using the same hydraulic jacks, the panels are separated from the product, and they are rolled back using the rail of the carriages. Similarly, open the longitudinal shields. The core is lowered as far as possible with the help of hydraulic jacks lifting and lowering. After a short exposure with a bridge crane using a traverse (not shown), the product is removed from the volume unit, i.e. stripping is carried out. The presence of a movable core in the vertical direction with expansion under the cone allows, after lowering it during stripping, to get the block room out of the molding cavity between the core and the airborne elements without damage and deformation.

As a result of this, the inventive device improves productivity.

The presence of essential features distinctive from the prototype allows us to recognize the claimed technical solution as new.

The possibility of implementing the claimed utility model in industry allows us to recognize it as meeting the criterion of industrial applicability.
