Connection system for rectangular steel pipe curtain wall cross beam and vertical column

Abstract

The invention discloses a connection system for a rectangular steel pipe curtain wall cross beam and vertical column. The connection system comprises the rectangular steel pipe vertical column and the rectangular steel pipe cross beam; the end of the cross beam is fixed to the side wall of the vertical column through a lateral connection component; and the front wall of the cross beam is fixed to the front wall of the vertical column through a front connection component. The lateral connection component comprises an elasticoplastic-deformation aluminum connection piece, one end of the aluminum connection piece is provided with a spring pine, and the other end of the aluminum connection piece is in threaded with an adjusting bolt; and the connection piece and the adjusting bolt jointly abut against the interior of a sealed cavity at the end of the cross beam by adjusting the depth of the adjusting bolt screwed into the aluminum connection piece. The front connection component comprises a vertical column connection part fixed to the front wall of the vertical column, the two sides of the vertical column connection part are connected with cross beam connection parts, and the cross beam connection parts are both fixed to the positions, on the two sides of the vertical column, of the corresponding front wall of the cross beam. Through the connection system, the rectangular steel pipe cross beam and the rectangular steel pipe vertical column can be firmly connected, the bearing capacity is high, the torsional rigidity is good, the phenomenon that the cross beam is twisted is avoided, the milling position avoiding problem does not exist, machining and installing are easy, convenient and quick, and the construction efficiency is high.

Description

technical field [0001] The invention relates to a beam and column connection system of a rectangular steel pipe curtain wall, belonging to the technical field of rectangular steel pipe curtain walls. Background technique [0002] The existing connection structure of the beam and column of the rectangular steel pipe curtain wall is as follows: Figure 1 to Figure 3 As shown, the connection between the rectangular steel pipe column 10 and the rectangular steel pipe beam 20 is realized by angle steel 32 and bolts 31. Specifically, a steel plate of the angle steel 32 is arranged on the end position of the beam 20, and the spacer 33 is placed through the bolt 31 is fixed on the side wall of the column 10, such as image 3 As shown, after the other steel plate of the angle steel 32 abuts on the front wall of the beam 20, it is fixed by screws 34. After the column 10 and the beam 20 are connected, the bases 42, 62 (the base 42 is fixed on the front wall of the column 10 by the scr...

Problems solved by technology

[0003] It can be seen from the actual implementation that image 3 As shown, the end of the rectangular steel pipe beam 20 needs to be opened to avoid the position, so that the angle steel 32 can be placed at the end of the beam 20. This connection structure belongs to eccentric force, and the stress state is not good, which is easy to cause the beam 20 torsion defect

Moreover, it is difficult to process the gap at the end of the beam 20, and the quality is difficult to control, and the sub-frames and other components at the position of the angle steel 32 also need to be milled and avoided, so there is a problem of complicated processing

In addition, for the superimposed curtain wall, the angle steel 32 and the bolt 31 occupy the position of the base, which will cause the problem that the corner of the glass panel 50 cannot be fixed
