Description

The invention relates to the field of construction, and more particularly to the construction of multi-storey buildings of frame type with transverse load-bearing walls and longitudinal self-supporting walls.

Enclosing structures of a multi-storey building are known, including transverse load-bearing walls and longitudinal self-supporting walls connected by a supporting frame (see RF certificate for utility model No. 24481, class E04B 2/02, 2002). One of the significant drawbacks of the known design is the low strength of the connection of the bearing walls with self-supporting longitudinal walls.

The closest analogue to the claimed technical solution is the application of R.F. No. 2006103118, class 04B 1/76, 2006, including a frame of reinforced concrete beams, transverse load-bearing walls and longitudinal self-supporting walls, hollow core slabs. At the junction of the transverse walls with the longitudinal wall, support pillows with embedded elements are installed in the transverse walls. Reinforced concrete beams are also installed on the support pillows, also equipped with embedded elements. Embedded elements of pillows and beams are welded together by electric welding. Masonry transverse and longitudinal walls at the intersection made in the dressing. However, the strength of the connection is insufficient.

The technical result of the claimed technical solution is the increased strength of the entire building. This is achieved by the fact that in the known device for connecting the outer walls of multi-storey frame buildings, including a frame of reinforced concrete beams, transverse bearing walls and longitudinal self-supporting walls with hollow core slabs, there are monolithic sections at the intersection of transverse and longitudinal walls made of concrete with reinforcement in mutually perpendicular vertical planes, moreover, installed along the axis of the transverse wall

continuous rods, and across it - split rods, and all of them are connected by mounting rods, forming a reinforcing system, and under the reinforced concrete beams embedded parts in the form of plates equipped with anchors and holes through which additional reinforcing rods are passed.

In addition, the technical result is achieved by the fact that an reinforcing cage is additionally installed above the reinforced concrete beams, the length of which is equal to the width of the monolithic section.

The technical result is achieved by the fact that in places where the floor slabs support the transverse end walls, wall elements are installed in the form of plates with holes in the form of a parallelogram in which the insulation is located.

Further, the technical result is achieved by the fact that under the reinforced concrete beams installed another reinforcing cage in a monolithic concrete belt, the length of which exceeds the width of the monolithic section.

The technical result is also achieved by the fact that at the borders of the monolithic section transverse walls and their continuation - loggias are made in a sawtooth shape. All these structural differences significantly increase the strength of the walls, especially if tensile forces arise along the axis of the transverse walls.

The claimed technical solution as an example is illustrated by drawings, where figure 1 shows a floor plan of a building; figure 2 shows the node "A" in figure 1; figure 3 is a section aa of figure 1; figure 4 is a section bB of figure 1; figure 5 is a section bb In figure 2; figure 6 is a section GG of figure 4; Fig.7 is a section DD DD of Fig.4; in Fig.8 - embedded part pos.19; in Fig.9 is a section EE in Fig.8; figure 10 shows the wall element pos.32.

The building in which the claimed technical solution is used consists of transverse walls 1 (Fig. 1), transverse end walls 2, to the outer layer of which a heater 3 is installed, and a facing layer 4 is installed behind the heater.

In the supporting end wall 2 and the facing layer 4, a masonry net 5 is installed through 4 rows.

The transverse wall 2 ends with the wall of the loggia 6.

The transverse wall 1 ends with the wall of the loggia 7. Between the transverse walls 1 there are hollow slabs 8, between the transverse walls 1 and 2 there are hollow slabs 9. Between the walls of the loggias 7 there are slabs 10, between the walls of the loggias 6 and 7 - slabs 11. Walls of the loggias 6 and 7 are insulated with insulation 12. The longitudinal walls 13 are made of two rows of blocks 14, between which foam concrete 15 is poured with a volume weight of 200-300 kg / m ³ (Fig. 1). Blocks 14 of the longitudinal walls 13 are mounted on prestressed reinforced concrete beams 16 (FIGS. 2, 3). Between the beams 16, a heater 17 is located (Fig. 4). At the ends of the beams 16 there are embedded parts 18 that are installed on embedded parts 19 located in the monolithic sections 20 of the transverse walls 1 and 2. The embedded part 19 is made in the form of a metal plate 21 with anchors 22 welded to it and two holes 23 (Fig. 8 and 9). Monolithic sections 20 are arranged in walls 1 and 2 on one side and the walls of loggias 6 and 7 on the other side.

In places where the floor slabs 9 are supported (FIG. 3), wall elements 32 are installed on the transverse end walls 2 in the form of flat plates with holes 33 in the form of a parallelogram in which an effective insulation is located. Brick masonry (figure 4) in the walls 1, 2 and walls 6 of 7 loggias is made in such a way that the bricks of the adjacent rows are offset relative to each other by 1/2 brick, as a result, the masonry of the walls at the border of the monolithic section has a sawtooth shape, which ensures reliable connection of the monolithic section with the walls of the building. The monolithic section 20 has reinforcement, which consists of vertical split rods 24, vertical continuous rods 25, which are installed in two mutually perpendicular planes, horizontal mounting fittings 26, grids of indirect reinforcement 27 (Figs. 4, 5, 6). Under the embedded part 19 in the monolithic section 20

(Fig.4) is the reinforcement of a monolithic belt, consisting of longitudinal reinforcement 28 and clamps 29 (Fig.7). Above the beams 16 is a reinforcing cage consisting of longitudinal reinforcement 30 and clamps 31.

If necessary, a monolithic belt with rods 28, 29 under the embedded part 19 can pass along walls 1, 2 and serves to absorb tensile stresses, in the absence of the latter, its length is limited by the width of the monolithic section 20 (Fig. 4). In this case, the reinforcement of the monolithic section takes up the efforts from the embedded parts 19 arising from loads through the beams 16. For more reliable fastening of the beams 16 in the monolithic sections 20, reinforcing bars 34 are installed in the holes 23 of the embedded parts 19, to which the grids 35 are attached.

Warming of the transverse end walls 2 is carried out by pouring monolithic foam concrete between the main bearing part of the wall and the facing layer 4 made of brick 120 mm thick.

The cladding layer 4 is laid on the wall elements 32, which are installed in one part on the supporting part of the transverse end wall 2, and the hollow plates 9 rest on them, and the second part of the wall elements cantilever protrudes from the wall, and the cladding layer 4 is laid on the cantilever part.

In the wall elements 32, thermal liners of effective heat-insulating materials in the form of parallelograms are installed between the wall and the facing layer. Filling of foam concrete can be carried out in two ways:

Option I is carried out after the completion of the masonry of the wall and the facing layer and the installation of wall elements and hollow slabs, through the holes in the thermal liners. This option is applicable mainly in the warm period of time.

II option. Wall masonry is carried out year-round; straight tubes in the transverse end bearing wall (left) are installed

and L-shaped and control tubes, necessary for monitoring the level of poured foam concrete.

Warming according to the second option is carried out in a warm period of time.

Masonry of walls, facing layer, installation of floor slabs, loggia plates, load-bearing beams, monolithic sections is carried out year-round.

To eliminate the formation of cold bridges in the walls of the loggias 6, 7 in the slabs of the loggias 10, 11 openings 36 are arranged in which a thermal liner 37 made of highly efficient heat-insulating material is installed.
