Description

The invention relates to construction and can be used in the manufacture of hollow-core reinforced concrete floor panels.

The goal and the invention is to increase the reliability and ability to manufacture products with multiple openings.

FIG. 1 shows an installation for forming hollow core panels, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section B-B-B in FIG. one; in fig. 4 is a view of B in FIG. 3; in fig. 5 - section GG in figure 1 .; in fig. 6 —formed panel, вид view from above; in fig. 7 — node I in FIG. 6; in fig. 8 is a section of the EE of FIG. 7; in fig. 9 is a section of an LF in FIG. 7; in fig. 10 is a composite luminaire.

The installation for forming hollow-core panels consists of a base 1, on which the vibrating plate 2 is fixed. On the latter, a pallet 3c is mounted with an on-board equipment consisting of transverse 4 and longitudinal 5 beads. The installation is equipped with a drive crossmember 6 on the rollers 7, on which the holders 8 are hinged. Traverse 6 is mounted on the rail track 9.

Cables 10 of the reversing drive 11 are attached to the traverse, thanks to which it is able to move the iio to the track 9 forward and backward. The reversible drive 11 is an electric motor with a gearbox and cables 10 slung over the blocks 12. The free ends of the formers 8 are supported on the support roller 13.

For insertion of void formers 8 into the form in the front transverse board 4, holes 14 are made, and in the back one - holes 15 of smaller diameter for trapping the nasal parts of the pusor current generators 8. Above the form at the facility there are devices for maintaining the nasal formers 8

form.

The device is made in the form of a different frame 16 with wheels 17 mounted on the track 9, and a frame 18 with rotatable L-shaped vertical holding elements 19. The frame is equipped with a reversing drive 20, which is

drawn on blocks 22.

On the frame 16 mounted vertical. Rack 23 with thread. Nuts 24 are screwed on the thread, the outer side surface of which is made in the form of gear rims (sprockets) for putting on the stub-roller chain 25.

On racks 23, by means of nuts 24, a stationary was installed, moving vertically along racks 23 while rotating nuts 24. Motor nuts 26 are provided for rotation of the nuts, connected to nuts in a roller-roller chain 25. Power supply to motor gearbox 26 comes through a flexible cable 27.

T-shaped supporting elements 19 are mounted on the frame. These elements have the ability to rotate 90 ° around the vertical axis using the device 28, which can be manually (from the handle 29) or mechanically driven.

For the manufacture of vertical openings in the plates, the installation is equipped with removable hollow cross-bars 30 mounted on top of the form with fixtures 31 fixed to them. The housing of each penetrator 31 is made of composite, for example, of three parts: two elements 32 and one element 33. parts 32 and 33, having wedge side faces, makes it possible to mold openings that expand into the interior of the product. In the lower part of the crosspiece 30 there are spikes 34 for fixing the elements 32 and 33, in their upper parts there are recesses for these spikes.

Traverses 30 are hollowed out. Winches, for example, of shaft 35 with ratchet mechanism 36, are mounted in their internal cavities. Cables 37 are attached to the winches, attraction elements 32 and 33 are attached to each other and to traverse 30. Removable crossheads 30 are fixed on boards 5 of the form using folding clamps 38..

The composite housing of the spacer 31 is designed in the form of a hexagon having a vertical axis and a symmetry axis. Its upper S and lower B bases have the form of a rectangle. Two side faces 2.9 parallel to the axis

void-forming 8, made at an angle to the base, descending downwards. and have longitudinal grooves of a segmented section with a radius equal to the radius-with-void-forming 8. Two other lateral faces W, are made at an angle to the base, diverging downwards. On the lower base, L, a longitudinal puzzle of a segmented section is made.

with a radius equal to the radius of the reinforcing bar 39, which passes under the puncher 31.

The location of the resulting vertical blind apertures 40 on the molded floor slab 41 is determined by the corresponding installation on the shape of the removable cross member 30 with the spacers 31.

The installation works as follows.

Pull on the armature. The formers 8 are introduced into the mold through the holes 14 in the front side 4 per part of their length. For example, with a length of 6 m, a hollow core 8 is inserted in 0.8-1 m. A drive 11 is used to move the hollow core 8.

On the removable cross braces 30, the elements 32 and 33 of the punchers 31 are secured with spikes 34. The elements 32 and 33 are fastened with the cable 37 by rotating the winch shaft 35. The winch ratchet mechanism 36 keeps the cable 37 in a tight position.

Removable crossheads 30 are installed on the sides of the form 5, passes the coreformers 8 into the grooves E of the segment section of the coreformers 31. The crossheads 30 are shifted to the front board of the four forms. The device is put into operation to support the nose section of the hollow formation 8. To do this, the frame 16 is moved by means of the actuator 20. The T-shaped retaining elements 19 are lowered, for which the gear motor 26 is lowered through the cable 27 and lowers the frame 25 by rotating the nuts 24 16 with elements 19 on racks 23.

The retaining elements 19 are included in the gaps between the hollow-forming elements 8. By moving the handle 29 of the device 28 elements

Then, actuators 11 and 20 are simultaneously turned on, and further void-forming 8 is pushed into the mold. The linear speeds of movement of the void-forming units 8 and the device for maintaining their bow parts are set to be equal. T-shaped elements 19 all the way forward support the void-forming 8, not allowing them to bend under the force of gravity. When the bow portions of the core holders 8 enter into the openings 15 of the tailgate, the actuators 11 and 20 turn off.

By the handle 29, the T-shaped elements 19 are turned by 90 and the reversible gearmotor 26 is turned on, which raises the frame 18 with the elements 19 to the extreme position above the form.

The supporting device using the actuator 20 is moved along the track 9 beyond the limits of the form. The removable cross braces 30 with the cutter 31 are moved to the working positions and fixed on the longitudinal sides of the mold 5. The form is filled with concrete and vibrated with vibrating plate 2,

Then the cables 37 are cut and the cross braces 30 are removed from the sides 5 of the mold. At the same time, the piercer 31 remains inside the molded article. A loading shield is lowered onto the form with the product with a lifting mechanism; and the concrete mix is additionally compacted by vibrating plate 2.

Then the waste formers 8 are removed from the product, the loading shield is removed. The pallet 3 with the molded article is sent to the steaming. After steaming, the hole formers 31 are removed from the products 41, for which their elements 33 are then removed, and then the elements 32. Non-vertical vertical openings 40 remain in the product. In the latter, the clamps of the load-lifting mechanism are placed. Products 41 remove the molds and send them to the finished goods warehouse.
