Q1

The invention relates to the construction, in particular to the joints of the connection of the elements of the metal frames of buildings and structures, mainly prefabricated columns and crossbars of I-sections.

The aim of the invention is to simplify and assemble as well as increase strength.

FIG. Figure 1 shows the assembly of the column with the pins before assembly; in fig. 2 - the same in the collection.

Top 1 and bottom 2 columns

for its sheet production 11 to enter the gap between the end ribs 8 of the crossbars, and the stops 6 are placed between the supporting flanges 4. The installation is completed by tightening the end ribs 8 with the upper bolts 9 and attaching the flanges 4 to the flanges of the crossbars with bolts 14.

The shear forces arising from the operational loads in the contact planes of the girders and ends of the columns are perceived by stops and flanges, and the vertically acting forces are transmitted from the column to the column.

connected to girders 3 by clamping 5 At the walls of the supporting ends of girders,

reinforced diaphragms 10 and end ribs 8 and are perceived by bolts and sheet releases.

neither from the supporting ends between the ends of the columns having supporting flanges 4, fixed to the tooiam shelves of column 1 and the flange 5 in the butt end of the wall of the column 2, the upper shelves of crossbars 3 are made with stops 6 mounted inside the flange between the supporting flanges 4, and the lower shelves are made with stops 7, installed in the circumference of the flange 5. The contacting side faces of the stops and (} of the trenches can be made with lateral bevels. The supporting ends of the crossbars 3 have end 8 connected to each other, for example, bolts 9, as well as. The diaphragm 10, gesture - - ko connected to the walls and straight bolts and columns 1 and 2 placed in the planes of the shelves. Each column may have walls welded into their walls, directed towards each other and pinched between the front ribs 8, and sheet releases 11. The supporting flanges 4 of the adjacent column 1 can be reinforced ribs 12 stiffness.

The assembly of the assembly is carried out in the following sequence.

Crossbars.3 lower the supporting ends on the column 2 installed in the design position in such a way that the stops 7 will rest on both sides
