Abstract

Use: for the manufacture of hollow building stones. The essence of the invention: removable pallet installation is equipped with roller bearings. The dividing walls are rigidly attached to the rig, which is connected to the removable pallet by means of fixing elements. The total surface area of the hollow cores and the pallet exceeds the total surface area of the walls along the inner perimeters of the cells formed by the pallet and the partition walls. 8 il.

Description

The invention relates to the building materials industry and can be used to make hollow concrete products.

A well-known multi-site installation for the manufacture of hollow building stones, comprising a base with a block of hollow-forming structures, a removable tray with openings for the latter, a closed side panel with mutually perpendicular partition walls installed in it.

A disadvantage of the known construction is low productivity due to the fact that the products at the first stage of the formwork are released only on two sides, while the other two and the base remain in conjunction with the internal formwork and are released only in the next final stage of the formwork. In addition, at the final stage of stripping, the adjoining of each product in three planes to the installation makes it difficult to remove the products without damage, which degrades the quality of the latter.

The aim of the invention is to increase productivity and improve product quality.

This is achieved by the fact that in a multi-site installation for the manufacture of voids, a removable pan with openings for the latter, a closed boron rig with mutually perpendicular partition walls installed in it, according to the invention, the removable pan is provided with Roller supports, the separators are rigidly attached to related equipment

removable pallet by means of fixing elements, while the total surface area of the hollow cores and the pallet exceeds the total surface area of the walls along the internal perimeters of the cells formed by the pallet, rolled up with boarding equipment and dividing partitions.

Fig. 1 shows a multi-site installation for the manufacture of hollow construction stones assembled with products and a set of contact evacuation boards, a longitudinal section; in Fig. 2 - the same, a transverse section; on fig.Z - the same, type in the plan; figure 4 - closed airborne equipment with dividing partitions, cross-section; figure 5 is a removable pallet, cross-section; figure 6 is a base with a block hollow, a cross-section; Fig. 7 shows a section A-A in Fig. 3, the relative position of the closed landing gear, the removable pallet and the base; on Fig - the finished product with non-through voids.

The multi-site installation for the production of hollow construction stones comprises a base, made in the form of a frame 2 permanently installed on supports 1, covered with sheet 3, to which hollow formers 4, rigidly attached in the required order, are made with inverse technological slopes. On the base there is a removable pallet consisting of a frame 5 covered by a sheet 6 with openings for the passage of hollow cores 4. On the frame 5 there are fixed supports 7 placed outside the working area of this installation, lug 8 (for lifting and moving the removable pallet) and holes 9. Buffer pads 10 are fixed on the lugs 8 to prevent the removable pallets from hitting each other while moving (for example, on rails).

Onboard equipment is mounted on a removable pallet, made in the form of a frame 11, inside which mutually perpendicular dividing partitions 12 are rigidly fixed.

On the frame 11, lugs 13 are mounted for demolding articles with a lifting device (not shown). A frame 14 with holes 15 for fixing is fixed on the frame 11 at the bottom along the perimeter.

The enclosed landing gear and removable pallet are interconnected by locking elements 16 passing through openings 9 and 15.

Inside the closed board equipment placed product 17.

In order to accelerate the compaction of the concrete mix, a set of contact evacuation boards is provided in this installation. Pins 19 are mounted on the removable pallet on the installation on the removable pallet. The shields 18 are suspended on the cross bar 20 on which the supports 21 with holes for the pins 19 are mounted. In the supports 21 there are holes for slinging the cable 22. The total surface area of the walls is

the perimeter of the cells formed by the base closed by the rigging and dividing partitions is less than the total area of all hollow cores located in this cell.

An example of calculation.

The number of voids in the product we denote K, the end of the product denote I, the longitudinal wall - II, and its bottom - III. Accordingly, the sides of the figure forming the void in the product are denoted by 1, 2, 3, and its upper plane is 4.

The area of the sides of the product will be equal to:

Si (Bi + B2) 0.5H; Sn () 0.5H

The sum of the areas of the side surfaces of the product will be equal to:

S6oK 2Si + 2Sn H (B + Bi + L + i).

Accordingly, for a figure that forms a void form (in this case, a truncated pyramid), the area of its side walls will be equal to:

S6oK 2S + 2Sii H (B + Bi + l + H).

The bottom area of the product is: SnrB-L;

The area of the bottom of the figure forming the void: I.

The area of the bottom of the product without voids: -ZZ.

The area of the upper face of the figure that forms the void:

For the correct sequence of stripping, the following condition must be met: (8bok + 8b) -) - 5d, i.e. H (B + Bi + L + Li) (b + bi + l + H) + bili + BL-kbl

For the calculation example, in this case, any given technological parameters can be taken.

Multiple installation for the manufacture of hollow building stones works as follows. A removable pallet is lowered onto the base with the block of hollowers 4 by means of a lifting mechanism, while the sheet 6 is mounted with holes 6 onto the hollow cores 4 and thereby fixed to the base. Then, a closed side rig is installed on top, holes 9 and 15 are aligned, and a fixing element 16 is inserted into them. After this, the installation is filled with concrete mixture of the required plasticity. Then, a set of contact evacuation boards 18 is installed on the installation using a lifting mechanism, with the pins 19 being installed in the holes of the supports 21.

The concrete mix undergoes vacuum compaction.

At the end of this process, a set of shields 18 is removed and the products are disassembled 17. In this case, the closed side equipment and the removable pallet are first unlocked, then the closed side equipment and the removable product pallet 17 are lifted in succession with a load-lifting mechanism. 7 to guides (not shown) for further transportation to the dosing chamber. A new removable pallet is installed on the base, the closed-type tooling is fixed and the process is repeated.
