Description

The invention relates to installations for the manufacture of reinforced concrete products of complex configuration, in particular window sill ventilation units for the influx of outdoor air.

A known form for the manufacture of reinforced concrete products, consisting of a pallet with a hollow core and sides (see SU, copyright certificate, 421509, class B28B 7/00, 1974).

The disadvantage of this form is that it is not suitable for receiving products with through holes.

The prototype of the invention is a device for the manufacture of double-row concrete heating devices, including a pallet with a divided wall mounted on a rigid frame with spindles, on which end walls with inserts for forming horizontal holes are fixed, longitudinal sides connected to the pallet and to the end sides by clamping locks ( see RU, patent 2101168, class B28B 7/00, 7/18, 1998).

A disadvantage of the known device is the inability to manufacture products with through horizontal holes and an internal chamber with a partition dividing the holes into two parts.

The invention is aimed at providing the possibility of manufacturing products with through horizontal holes shared by an internal chamber with a partition.

The result is achieved by the fact that the device for the manufacture of window sill ventilation units for the inflow of external air, containing a pallet mounted on a rigid frame equipped with spindles, to which end walls with rods and an insert for forming horizontal holes are attached, and longitudinal sides connected to the pallet and the end sides of the clamping locks, according to the invention is equipped with a removable U-shaped box, one wall of which on the inside has a zigzag surface, and the upper wall and - a longitudinal opening, fixed on the frame via rods and screws and condensate drain formed as a box with a pipe.

The result is also achieved by the fact that in the method of manufacturing window sill ventilation units for the influx of outdoor air, which consists in preparing the device for manufacturing in working condition with the installation of forming parts in the form of rods, insert; cleaning and lubricating surfaces; installation on a vibrating platform, filling the mold with concrete followed by compaction, concrete hardening, disassembling the device for manufacturing and shipment of the finished block, according to the invention, an U-shaped box is additionally mounted on the frame and the mold is filled with concrete in 2 stages, first filled with concrete to the top of the U-shaped box, after the concrete has hardened, the U-shaped box is removed, installed on the hole obtained and the steam trap is fixed, the tube of which is installed in the provided end hole block and fill the form to the top edge of the sides.

Figure 1 schematically shows a device for the manufacture of window sill ventilation units for the influx of external air, General view (the right lead screw, rods and liner are not shown conventionally); figure 2 is a section 1-1 before removing the U-shaped box; figure 3 - section 1-1 after installation of the steam trap.

The device comprises a base plate 1 with a rigid frame 2, with spindles 3 and attached to the base plate 1 and frame 2 using fixed channels 4, a shape consisting of a pallet 5 connected to it by hinges 6 of the longitudinal sides 7 and 8.

The end walls 9 and 10, in order to ensure the possibility of their movement, are connected by means of plates 11 to the lead screws 3. For the formation of horizontal horizontal holes in concrete, the rods 12 and the insert 13, made of a rectangular shape with a small technological cone, are welded to the inner surface of the end walls 9 and 10 .

U-shaped box 14 with the help of rods 15 and screws 16 is attached to the frame 2. The walls of the box 14 have small slopes to provide easier removal from the product. One wall of the box on the inside has a zigzag surface, and the upper wall has a longitudinal hole.

The movable end 9, 10 and longitudinal 7, 8 sides are tightly pressed between each other and the pallet by clamping locks 17. The end board 10 has a groove 18 for passing the steam trap tube 19, made in the form of a box with a tube, and a stopper (in figure 1 not shown) for fixing the tube in a predetermined position. The dimensions of the trap box are consistent with the dimensions of the U-shaped box. 20 - loop, 21 - plate-plate welded to the rods 15, is used to extract the U-shaped box 14.

A method of manufacturing a window sill ventilation unit for the influx of outdoor air is as follows. To prepare the device for manufacturing the block, the clamping locks 17 are unscrewed, the end plates 9 and 10 are pushed to the right and left, the longitudinal sides 7 and 8 are opened, the U-shaped box 14 is installed and fixed with screws 16 on the frame 2, then cleaned and lightly lubricate the entire inner surface of the mold with lubricating oil, i.e. pallet 5, the surface of the U-shaped box 14, the end walls 9 and 10 with the rods 12 and the liner 13, the longitudinal sides 7 and 8. After that, close the longitudinal sides 7 and 8 and return the end walls 9 and 10 with the lead screws 3 to the original position, and close the clamping locks 17.

The device is moved to a vibrating platform under a paver, where in 2 stages the mold is filled through a funnel with a light concrete mixture of the desired composition and compacted. Control over filling the mold with concrete is carried out visually. At the 1st stage, the form is filled to the top of the U-shaped box 14. After that, the funnel of the paver is removed and after the concrete has hardened with the help of the lifting mechanism, hooking on the loops 20, the U-shaped box is removed 14. At the 2nd stage, the hole from A U-shaped duct 14 is installed with a steam trap 19, the tube of which has a slight upward slope and enters the groove 21 of the end face 10. The steam trap 19 is fixed with a locking screw (not shown in the drawings). After checking the correct installation of the steam trap 19, the mold is filled with light concrete mixture to the upper edge of the sides of the mold. Then produce heat treatment. The form from the steaming chamber is moved to the formwork station, where first the steam trap tube 19 is released from the locking screw and the lock locks are unscrewed, the end walls 9, 10 are pushed out with the help of the lead screws 3 and the longitudinal movable sides 7 and 8 are opened, then with the help of the lifting mechanism and special lifting devices lift the finished unit and sent to the warehouse.

After cleaning and lubricating, the device is ready for use again.

The proposed device allows the manufacture of reinforced concrete products with complex internal voids.
