Description

 The invention relates to the production of reinforced concrete products, in particular monolithic volumetric blocks of the glass type.

 A known installation for the manufacture of volumetric blocks, including a rigid core and sliding vertical outer shields (see, for example, Monfred J. B. et al. Buildings from volumetric blocks. M: Stroyizdat, 1974, p. 253-274).

 Closest to the invention, the technical solution is a unit for forming volumetric blocks, including a core with rotary longitudinal and transverse shields, tilters, assembly, forming, heat treatment and formwork posts [1].

 Significant disadvantages of the known solutions are low efficiency, due to not quite sufficient productivity of the installation, as well as its significant material consumption.

 The aim of the invention is to increase the efficiency and reduce the material consumption of the installation by eliminating the noted disadvantages.

 The essence of the invention lies in the fact that the installation for forming volumetric blocks, including a core with rotary longitudinal and transverse shields, tilters, assembly, forming, heat treatment and stripping posts, is equipped with an additional core with rotary longitudinal and transverse shields and an additional heat treatment post, at the cores are made with supports for shields and installed with the possibility of reciprocating movement along the axis of the installation, and the heat treatment posts are located with opposite sides relative to tilters.

 In addition, the longitudinal and transverse panels can be equipped with airborne elements located along their perimeter, and airborne elements can be made folding or removable.

 Compared with the prototype [1], the invention contains new features, consisting in the presence of an additional core with rotary longitudinal and transverse shields and an additional post of heat treatment, while the cores are made with supports for the shields and are installed with the possibility of reciprocating movement along the installation axis, and heat treatment posts are located on opposite sides relative to the tilters.

 Longitudinal and transverse panels can be equipped with airborne elements located along their perimeter, and airborne elements can be made folding or removable.

 As follows from the foregoing, the invention is new because it is not known from the existing level of technology and, in addition, it has an inventive step, since it does not explicitly follow from it.

 The invention is industrially applicable, as it can be actually used in construction.

 In FIG. 1 shows a setup for forming volumetric blocks, side view; in FIG. 2 - the same, top view; in FIG. 3 - core with shields and product (fragment), horizontal section.

 The installation consists of two movable cores 1 and an additional 2, two pairs of longitudinal 3 and 4, two pairs of transverse shields 5 and 6. Cores 1 and 2 have supports 7 for shields and are equipped with wheels 8, with the help of which they move along the rail track 9.

 The installation also has stationary tilters 10 with hydraulic cylinders 11 that translate the boards from horizontal to vertical. The hydraulic cylinders 11 are connected to the pumping station 12.

 At the location of the tilters 10, a flyover 13 with a paver 14 is installed.

 At the end of the rail tracks 9 is located the mechanism 15 of the reciprocating (shuttle) movement of the cores with a chain or cable drive 16.

 At the location of the tilters 10 there is a stationary post 17 of stripping, cleaning and lubricating the core and, possibly, reinforcement panels, assembly panels, molding. Outside the tilters 10 to the right and left of them are two posts 18 and an additional 19 heat treatment with a supply of 20 coolant, such as steam.

 The design of the longitudinal shields 3 and 4 and the transverse shields 5 and 6 may be different. If it is necessary to form volumetric blocks with external wall panels, the panels have side elements 21 of a height corresponding to the thickness of a single-layer or multi-layer panel. The side elements 21 can be reclining or rigidly attached to the shields, as well as removable.

 The boards in the installation, depending on the purpose of the wall, can be changed to another set, for example, a shield for forming an internal wall or a shield for forming an external wall can be installed on the same tilter.

 The installation works as follows.

 The core 1 is located at a stationary post 17 in the area of the tilters 10, and an additional core 2 with shields 4 and 6 at the heat treatment station 19. At the post 17, longitudinal 3 and transverse 5 shields of the core 1 with tilters 10 with hydraulic cylinders 11 and stations 12 are torn off core 1, are removed from the supports 7 and are transferred to a horizontal position.

 An article is removed from the core 2 with a bridge crane using a traverse (not shown) - a volume unit, i.e. stripping is carried out. Next, the shields 3 and 5 and the core 1 are cleaned and lubricated, reinforcing cages are placed on the shields. On the shields of the outer wall panels with side elements 21, the concrete mixture is laid and compacted. This operation can also be carried out aside on a vibrating platform, where the panels are moved using a bridge crane (not shown).

 Next, the outer panels with concrete mix and the panels of the inner walls with reinforcing cages are transferred using tilters 10 from horizontal to vertical position, rely on supports 7 of core 1, are pressed to the core and locks are closed.

 In this case, the side side elements of 21 shields (see Fig. 3), on which the concrete mixture is laid, serve to prevent the destruction of the shape given to it and allow the use of more mobile mixtures than without them. If the block is transverse and longitudinal formed by external wall panels, then the lateral side element 21 of the transverse wall can be folded down after being pressed against the core, and the lateral side elements of the longitudinal wall can be rigidly connected to their shield and have a slight slope for stripping or, conversely, transverse board shields fixed elements, and in longitudinal - reclining. Folding the airborne element after raising the shield allows you to connect the longitudinal and transverse wall panels.

 Concrete mixture is fed into the formed molding cavity 22 between the inner wall shields and the core and onto the ceiling using the paver 14, it is compacted by the mounted vibrators of the shields, i.e. a new product is molded.

 Next, the tilters 10 are lowered, and the core 1 with shields 3 and 5 and the product is fed by a reciprocating mechanism 15 to the heat treatment station 18, where the energy carrier 20, for example steam, is connected and the product is heated.

 Then, at the post 17 with tilters 10, using the same reciprocating mechanism 15, the core 2 with its shields 4 and 6 and the heat-treated product at post 19 is rolled along the track 9. Here, the shields 4 and 6 with the help of tilters 10 are torn off from the product, transferred to a horizontal position and the manufacturing process of the volume unit is repeated. Then the core 2 with shields moves to the warming station 19, and from the heat treatment post 18 to the post 17 the core 1 is rolled.

 Thus, the shuttle movement of two cores with shields with one set of tilters allows you to double the productivity of the installation, reducing the cost of funds and metal on tilters, hydraulic cylinders, pumping stations, overpass and paver.
