RU54059U1 - INTERFACE FOR METAL TWIN-BEAM METALS OF THE SAME HEIGHT - Google Patents

Abstract

Usage: in the construction of domes, girders, floors. SUBSTANCE: node of coupling of metal I-beams includes a main beam, a secondary beam and a metal plate welded to the lower shelves of the beams, in the main beam in the upper shelf there is a triangular cut with an angle at the apex of the triangle of 85-90 degrees, and the secondary beam has protrusions of the upper shelf in the form of a triangle with an angle at the apex of the triangle 85-90 degrees and a cutout of the lower shelf by the size of the protrusion of the lower shelf of the main beam. The upper shelves and the walls of the beams are fixed to each other for assembly welding. Between the wall of the secondary beam and the lower shelf of the main beam there is a gap of 3-3.5 mm. The advantage of the proposed node pair of metal I-beams is that the reliability of the connection.

Description

The utility model relates to construction, namely to the pairing of metal beams, can be used in the construction of domes, beam platforms, floors.

A known node pair of metal I-beams of the same height, including the main beam, the secondary beam and a metal plate welded to the lower shelves of the beams (1).

The disadvantage of this node pairing metal I-beams is that during installation and operation is possible deflection of a metal plate welded to the lower shelves of the beams.

The technical problem, which the utility model is aimed at, is to ensure higher reliability of the connection with the same complexity of manufacturing a node for pairing metal I-beams.

The technical result is achieved by the fact that the proposed utility model includes a main beam, a secondary beam, a plate welded to the lower shelves of the beams. The main beam has cutouts in the upper shelf of a triangular shape with an angle at the apex of the triangle of 85-90 degrees, and the secondary beam has protrusions of the upper shelf in the form of a triangle with an angle at the apex of the triangle of 85-90 degrees and a cutout of the lower shelf. The upper shelves and the walls of the beams are fixed for assembly welding.

The utility model is illustrated in the drawing. Figure 1 shows the node pair of metal I-beams of the same height and its cross-section 1-1 and 2-2.

The junction of metal I-beams consists of a main beam 1, a secondary beam 2, in the upper shelf of which there are protrusions 4 of a triangular shape, and a plate 3 welded to the lower shelves of the beams. Between the wall of the secondary beam and the lower shelf of the main beam there is a gap of 3-3.5 mm.

This utility model is performed in the following sequence: in the main beam, cuts are made in a triangular shape with an angle at the apex of the triangle 85-90 degrees, weld the plates to the lower shelf of the main beam, make protrusions in the upper shelf of the secondary beam in the form of a triangle with an angle at the top of the triangle 85- 90 degrees and cutouts of the lower shelf of the secondary beam by the size of the protrusion of the lower shelf of the main beam. After mounting the main beams on the plate, a secondary beam is installed and the upper shelves of the beams, walls and the lower shelf of the secondary beam and plate are welded.

The advantage of the proposed node pair of metal I-beams is that the reliability of the connection.
