The invention relates to the construction of coatings for industrial buildings with chimneys and installation of ventilation units.

The purpose of the invention is to ensure the reliability of work when attaching a pipe to trusses covering an industrial structure.

FIG. Figure 1 shows the coating, an industrial building in terms of upper farms, secondary, type; in fig. 2 - the same, in terms of lower farms; in fig. 3 shows section A-A in FIG. 1 and 2; in fig. 4 — node I in FIG. one; in fig. 5 — node II in FIG. 2; in fig. 6 — node III in FIG. four; in fig. 7 is a section BB in FIG. 6; in fig. 8 - node IV in FIG. five; in fig. 9 is a section bb of FIG. eight; in fig. 10 shows a section of YYY in FIG. 6

The coating of an industrial building consists of parallel-mounted trusses 1 with regular pitch, perpendicular to them placed beams 2 and rows of exhaust pipes 3, stirred symmetrically with respect to the pitch of farms and fixed in the planes of the upper and lower trusses 1 by means of the corresponding. their top 4 and bottom 5 lattice elements. The upper joints are made in the form of frames 6 of horizontal laying legs, their rods 7 and stiffening ribs 8, and vertical swivel joints 9 of the exhaust pipes and the cover.

The lower nodes 5 of the interface are made in the form of frames 10 of horizontal-vertical support from supporting rods — the main 11 and auxiliary 12 and rigid attachment 13 of the chimney and non-identical rods of the frames 10.

The support for the supporting rods 7 of the horizontal support frames 6 are the upper trusses of the trusses I. The support for the supporting rods of the frames 10 of the horizontal vertical support are the beams 2 adjacent to the attachment points of the lower trusses 1.

The exhaust pipe 3 in the zone of passage through the upper frame 6 is provided with one annular stiffening rib 14 connected to the supporting rods 7 of the frame 6 by means of vertical hinged joints 9, made in the form of bent plates 15, and angles 16 enabling the pipe to move 3 in a vertical plane.

The carrier rods 7 are rigidly connected with profiled flooring 18 by means of self-tapping screws 17, and are connected to sheet 19 to allow the passage of pipes 3 and interconnect with each other by a sheet section 20 provided with a circular opening 19 for the bowl 19, which is attached to the sheet diaphragm 20 by means of corners 21.

In the zone of passage through the frame 10 of the lower lattice element, the exhaust pipe 3 is equipped with two annular stiffening ribs 14, into the gap of which, during the installation of the pipe 3, the support table 22 is fixed, resting on top of the main 11 and auxiliary 12 bearing rods of the frame 10 of the lower unit 5 mates The rigid attachment 13 of the exhaust pipe to the supporting rods of the frame 10 is made by bolting the annular ribs 14 with the table 22 and the table 22 with the supporting rods 11, 12.

For more reliable operation of the annular ribs 14 stiffness in the level of the upper ring 14 (see Fig. 9, 10) a transverse stiffening rib 23 is welded corresponding to the wall of the support table 22.

The forces acting on the coating are distributed in it as follows.

The main 11 and auxiliary 12 rods of the frames 10 adjacent to the transverse beams 2 transfer the vertical loads from the exhaust pipes 3 to the attachment points of the roof trusses 1. The main supporting rods 11 of the frames 10 together with the trusses themselves and the horizontal stiffeners 24 that perform the role of a diagonal lattice with the inclusion of beams 2 as racks in the communication system of this lattice; 5 create a horizontal longitudinal wind farm. The wind farm supports are vertical links of the coating, connected to it with the help of spacers of the cover.

The transverse wind farm is created by a system of the same horizontal stiffening elements 24 and bearing rods 11 of one of the frames K. The trusses themselves are beams 2. The transverse wind load is thus transmitted directly to the lower nodes of the truss trusses on the braces. 5 Through the support table 22, the force arising from the weight of the exhaust pipe is transmitted to the lower attachment points of the trusses.

In the upper level of the sa horizontal rigidity elements 24, together with the trusses themselves, create horizontal longitudinal wind trusses, similar to the trusses at the level of the lower trap and perceive only horizontal wind loads.
