The invention relates to construction and can be used in the construction of vaulted buildings in permafrost areas.

The purpose of the invention is to increase reliability and reduce material consumption and labor intensity in the construction of a vaulted building with a ventilated underground.

FIG. 1 shows a vaulted building; in fig. 2 — node I in FIG. one.

The vaulted building includes the construction of the arch 1, supported on the foundations 2, taps 3, the floor slabs 4 and the supports 5.

The foundations 2 are made in the form of trusses 6, mounted on supports 5 in the places of the joining: at the extreme posts 7 with the lower catfish and partially buried in the ground 9.

Extreme pillars 7 and lower along with 8 trusses 6 have a hollow section and are interconnected with the union of their cavities. Extreme supports 7 are made with openings 10 for the passage of cold air. The plugs 3 are formed by the upper core of 11 trusses 6. The supports 5 are made of pipes, filled with eutectic and hermetically sealed at the ends.

Fastening of the structure of the roof I with the upper 6 cattle 11 trusses 6 is made on the installation welding. The draw bars 3, the trusses 6 and the supports 5 are made of steel: the fixings 3 are made of channel bars, the outer posts 7, the bottom B of the trusses 6 and the supports 5 are made of pipes. In places of the openings 10, the outermost supports 7 can be equipped with nozzles 12 for connecting fans.

The vaulted building functions as follows.

The load from the dead weight of the roof structure 1, snow and overhead transport (if available) is transmitted through the supporting parts of the roof 1 structure to the foundations 2, which function as a truss 6. The horizontal component of the load (thrust) is perceived by the upper rim 11 truss 6. The vertical component of the load from the structure of the roof 1. and the load from the overlap are perceived by the trusses 6 and transmitted through the bottom 8 to the ground 9 of the base. To level the plot of the stresses in the ground 9, the extreme legs 7 of the trusses 6 have supports 5, which accumulate cold due to filling them with eutectic and reduce the depth of ground 9 of the base along the building perimeter during the summer period. Preservation of soil 9 of the base in the frozen state is mainly provided by a ventilated underground unit 13, which is formed by means of trusses 6, partially embedded in the ground 9. To quickly form the design temperature of the soil 9 of the base during construction or during operation (in case of emergency thawing)

hollow outer posts 7 and lower 8 ca 6 trusses are used, the cavities of which communicate with each other. Cold air is blown through them, the intake and extraction of which is carried out through the holes 10 specially provided for in the extreme uprights.

The installation of the vaulted building is carried out as follows.

After the preparation device, the supports 5, the top of which is located at the preparation level, are installed from the non-soil soil, then the trusses 6 are installed and after the vertical connections are established between the two extreme trusses 6 and the soil is filled up to the desired level, the installation of the arch 1 and slabs is completed block 4 farms 6.

When arranging the vertical leveling with bedding, and cutting for the installation of trusses 6, trenches are laid, in the places of installation of the supports 5 they are made broadening. After installing the trusses 6, trenching is performed.

Due to the fact that the puffing 3 and the top som 8 of the trusses 6 are the same element, the tensile forces arising in the pulling 3 from perceiving the thrust of the structure of the roof 1, and the compressive forces acting in the upper All 11 farms 6, partially or fully compensate each other. The cross section of the clamping 3 (upper section - 11 of the truss 6) is selected according to the resulting value of the indicated efforts. The trusses 6, partially embedded in the ground 9, are at the same time the foundations 2. The trusses 6 work as structures on an elastic foundation, and as a result, the total bending moment in them and the normal forces in them are reduced.
