Abstract

Usage: the construction of steel frames of buildings. SUMMARY OF THE INVENTION: multi-story columns and crossbars are formed of two channels. Channel bars of the columns are shelves to each other and are interconnected by plates. To the latter, support tables are mounted under and above the crossbars, which are located in two mutually perpendicular directions with a gap relative to the upper table and the vertical column shapes in which the spacers are placed. The channels of the crossbars are arranged side by side to each other and are connected to the supporting tables and packaging by means of bolts. 4 ill.

Description

The invention relates to construction and can be used in the construction of steel frames of buildings.

The closest in technical essence and the achieved result is the steel frame of the building, which includes composite columns with bezels and girders, the latter of which are located in two mutually perpendicular directions and are rigidly attached to the columns.

A disadvantage of the known frame is the increased complexity of manufacturing and installation.

The aim of the invention is to reduce the complexity of manufacturing and installation.

This goal is achieved by the fact that in the steel frame of the building the columns are multi-storey, and the crossbars and columns are in the form of paired channels, and the channels of each column are mounted outward, connected by shelves by means of overlays and equipped with supporting tables attached to the latter and the walls of the channels under and above crossbars, the last of which are installed with a gap relative to the shelves of the crossbars, and the shapes of the columns are attached vertically to the walls and overlays and installed between the walls of the channels of the crossbars with a gap flax them and supporting tables, the channels of each set Riegel shelves outward equipped with steel spacers mounted in the gaps between the walls of the U-sections luminaire crossbars and columns, and connected to the latter and with the support tables columns.

The steel frame of the building comprises columns 1 and crossbars 2, rigidly attached to columns 1 and arranged in two mutually perpendicular directions.

Columns 1 and crossbars 2 are made in the form of paired channels 3 ,. The columns have a height of several floors.

The channels 3 of each column 1 are installed by the wall 5 to the outside, interconnected by shelves 6 by means of plates 7 and provided with supporting tables 8, which are attached to the plates 7 and walls 5 of the channels 3 both under and above the crossbar 2.

The upper supporting tables 8 are installed with a gap of 9 relative to the shelves 10 of the crossbars 2.

Shapes 11 of the columns 1 are attached vertically to the walls 5 and plates 7 and installed between the walls 12. channels k crossbars 2 with a gap of 13 relative to them.

The channels k of each crossbar 2 are installed with the shelves 10 to the outside and are equipped with steel gaskets 1, which are installed in the gaps between the walls 12 of the channels k, the crossbars 2 with the chamfers of 11 columns 1. The channels of the 4 crossbars with chamfers 11 columns of the tables 7 columns of bolts 15.

The installation of the steel frame is carried out in the following order.

Columns T are mounted. After this, the installation of crossbars 2 begins. Two channels 4, crossbar 2 are immediately suspended from the crane hook on the lines and lowered on both sides of the tables 8. Then the ends of the channels 4 are introduced into the space formed by the tables 8 and

to each other and to the tables with 8 bolts 15.

With this installation of the frame there is no welding work.

The frame construction allows one to obtain both hinge assemblies of the columns 1 and crossbars 2, as well as rigid ones, for example, in case of using the hinge assembly, it is sufficient to attach the channels k of the crossbar 2 to the vertical gusset 11 and the lower supporting table 8.

When the crossbar 2 is rigidly connected to the column 1, the first one is still bolted to the upper table 8 and, in addition, a plate is inserted into the gap 9.
