The invention relates to the production of concrete and reinforced concrete building products with veneer.

The purpose of the invention is to increase the reliability of fastening of facing slabs to concrete.

The essence of the method lies in the fact that before laying the concrete mixture into a mold, a matrix is installed, made with jagged protrusions with vertical abutment surfaces, and of the hem, facing slabs with an overlap relative to the jagged protrusions equal to 0.01-0.1 of the slab length, and laying the concrete mix is made from the side opposite to the admission of the facing plates. The fixing of the facing plates is carried out with rods by passing them through the holes in the sides of the mold. under the overlap of each plate.

The facing plates are laid with an overlap relative to the projections of the relief matrix, which ensures the pinching of the protruding part of the plate in the structural layer of the product, which acts as an anchor. In addition, in the finished product, protruding above the surface of the tor1; s plates, closing the horizontal seams of the cladding, protect it from moisture from atmospheric precipitation.

The concrete mix is placed from the side of the founding in the cavities of the matrix of facing plates, which prevents their separation from the matrix, increases adhesion to the structural layer and eliminates the leakage of the cement milk under the front surface of the plates.

The ends of the plates, located in the hollows of the relief matrix, are pressed by fixing elements across the entire width of the matrix, which increases the rigidity of fixing the plates on the matrix, thereby eliminating their displacement during vibratory compaction of the concrete mix.

Figure 1 shows a mold for making products with plates laid on it, top view; figure 2 - section aa in figure 1; on fig.Z - node 1 in figure 2.

The form for the manufacture of building products consists of a pallet 1, sides 2 attached to it and a relief matrix 3 laid on pallet 1 and fastened with screws on it. The form is equipped with retaining rods.

4, passed through the holes 5 in the opposite sides of the form.

The matrix 3 is made with toothed protrusions with vertical abutment surfaces 6 and edges 7 inclined thereto. The height of the vertical abutment surface 6 is equal to the sum of the width of the horizontal seam 8 of the facing and the thickness of the facing plate 9. The width of the inclined face 7 is equal to the difference of the side size of the laid plate 9 and the magnitude of the inlet 10 of the plate 9 relative to the vertical stop surface 6. The fixing rods 4 are located close to the vertical stop surface 6 of the matrix 3 and at a distance equal to the thickness of the facing plate 9.

The method of facing building products is carried out as follows.

On the pallet I of the form they lay the relief matrix 3, on the inclined edges

5 7 protrusions of the relief matrix 3 stack the slab with an overlap of 10 equal to 0.05 of the length of the facing tiles 9. The ends of the plates 9, located in the hollows of the relief matrix, press the fixing rods 4 to it across the entire width of the matrix. З.г Laying the concrete mix of the structural layer 11 is started from the side of the pressed ends of the plates 9. After that,

g compaction of the concrete mix on the vibrating table for 50 s. Then, through the holes 5 in the beads 2 of the form, the fixing rods 4 are removed. At the same time, grooves (tears) 12 are formed at the locations of the fixing rods 12. After this, heat treatment is performed at 85 ° C for 10 hours, then the product is held for 3 hours under normal conditions and . dismantling for5 m1.

The size of the inlet of slabs less than 0.01 the length of the facing slab does not ensure the reliability of its attachment to concrete. The size of the inlet plates more than 0.1

0 the length of the facing plate leads to a deterioration of the seam filling.

Test data on the adhesion of facing plates to concrete are presented
