The single-storey frame-panel building contains foundations 1 with glasses 2, wall panels 3 with horizontal edge 4, window opening 5 and vertical edges 6, ribbed plates 7 of the gable floor 8. Wall panels 3 have one window opening 5 or more window openings 5, like this is shown in FIG. 3. Vertical edges 6 are located on the outside of the wall panels 3 and along the edges of the window opening 5 (central in variant

those wall panels 3 with several window openings 5) and are made with a protrusion 9 beyond the outer edge 10 of panel 3 and a notch

11 in the upper end. The wall panels 3 are articulated to the foundations 1 by installing protrusions 10 in the glasses 2 of the foundations 1. The horizontal edge 4 of the wall panels 3 is located along the central transverse axis of the panel 3 between the vertical edges 6 and acts as a spacer.

The plates 7 of the coating 8 are made with one pre-stressed longitudinal edge 12 of variable cross-section, located along the central axis, and transverse ribs 13. The plates 7 of the coating 8 are supported freely and cantilevered by the longitudinal edge

12, the upper end of the vertical rib 6 of the wall panels 3 at the site of the notch 11. The joined edges of the longitudinal rib 12 and the vertical rib 6 are Z-shaped.

The fastening of the plates 7 of the coating 8 with the wall panels 3 is carried out using inclined tacks 14 connecting the outer end of the longitudinal ribs 12 of the plates

7cover 8 with vertical edge 6 of wall panels 3 in its lower part. The angle of inclination of the tips 14 to the vertical edge 6 is equal to the angle a of the inclination of the plates 7 of the cover

8k horizontal. The joint between the shafts 14 and the longitudinal edge 12 is located above the neutral axis of the plates 7 of the coating 8.

The longitudinal ribs 12 of the plates 7 of the coating 8 are interconnected along the central axis of the building in the ridge hinge with bolts 15 and overlays 16. On the plates 7 of the coating 8, an insulated roof is installed from the insulation layer 17 and the roofing 18. In the longitudinal direction the plates of the coating 8 are interconnected welding of embedded parts 19, followed by sealing the joints with a sealant.

To reduce the thickness of the shelves 20 of the plate 7 of the cover 8, they are provided with transverse ribs-diaphragms.

The wall panels 3 are made of three layers with an external base layer 21 made of heavy concrete, an intermediate layer made of structural heat insulation layer 22 made of polystyrene or large pore ceramisite concrete and an internal layer 23 made of lightweight concrete.

The wall panels 3 are reinforced with spatial frames 24 including longitudinal 25 and transverse 26 rods, made in conjunction with frames 27 and 28 of vertical 6 and horizontal 4 edges. In the nadoporny zone, additional reinforcement 29 is installed in the form of a set of curvilinear rods located diagonally and crosswise in plan.

The frame-panel building was erected in the following order.

Foundations 1 are installed on the prepared base, on which wall panels 3 are mounted and fixed by side mounting braces. Then they are placed on the wall panels 3 of the slab 7 of the coating 8, resting their longitudinal ribs 5 and 12 on the vertical ribs 6 of the panels 3 of them

Z-shaped edges. Connect plate 7

cover 8 in ridge knot overlays 16

and bolts 17 with the formation of a hinge. With

In this case, the slab 7 of the cover 8 is supported on a height-adjustable tower.

Then, the plates 7 of the coating 8 are connected to the wall panels 3 by means of inclined tacks 14c fixing them in the attachment points by the plates 30, washers 31 and nuts

5 32.

After aligning the vertical position of the wall panels 3 and the free working length of the grout 14, remove the side mounting braces and gradually reduce

0 height of the mounting tower, thereby ensuring the uniform inclusion of the tool 14 in the work. The wall panels 3 are interconnected by welding the inserts 33. Sealing the joints between the wall pa-.

5, 3 is carried out by compressing the sealant, for example, a vapor-insulated cord, previously attached in the joint zone to one of the adjacent wall panels 3. For mounting 7 covering plates 8 and

0 wall panels 3 they are made with mounting and lifting loops 34.

The tightening device 14 provides for the formation of a triangular stiffener, while bending moments occur

5 only in the fins 12 of the slab 7 of the coating 8. The bending moment is almost unambiguous along the entire length, which makes it possible to rationally and fully use the prestressing of the reinforcement in one

0 plane.

Similarly, the voltage is optimally distributed from the vertical forces, i.e. the vertical edges 6 of the wall panel 3 work only in compression, and the puff 14 and

5, the prestressed reinforcement in the slab 7 of the cover 8 only works in tension.

2, the shape of the butt surfaces of the longitudinal ribs 12 plates 7 of the cover 8. vertical ribs 6 of the wall

the panels 3 and the free support of the plates 7 of the panel 3 in the plane of their ribs 6 avoids the need to arrange the horizontal rib 4 in the upper part of the wall panel 3 and simplify the joint, which reduces the metal consumption of the joint and the material consumption of the wall panel 3.

The equality of the angles between the tie 14 and the vertical edge 6 of the wall panel 3, between the slab 7 of the cover 8 and the horizontal provides minimal effort in all elements of the building, if they are unambiguous across the entire plane of the elements.

The location of the top fixing unit of the shafts 14 above the neutral axis of the plate 7 of the coating 8 allows both stretched reinforcement of the rib 12 and part of the compressed reinforcement of the shelf 20 to be activated, which reduces the consumption of materials of the plates 7 of the coating 8.

The interconnection of the vertical fins 6 of the wall panels 3 by the horizontal edge 4, located along the central transverse axis of the panel 3, provides a 20–45% reduction in shear stresses in the vertical fins 6.

Placing a horizontal edge in any other plane leads to a mismatch between the center of torsion and the center of gravity of the section, which causes the occurrence of additional shear stresses.

The invention makes it possible to reduce the material consumption of a building and the laboriousness of its construction, as well as to increase its operational reliability.
