[0002] In the installation of construction equipment, the installation of a suspended ceiling for building decoration, etc., a hanger rod needs to be connected with a floor slab or a beam. The connection of a hanger rod with a reinforced concrete floor slab or a beam is generally achieved by using a pre-buried part or a post-embedded expansion anchor bolt, and the connection of a hanger rod with an I-shaped steel beam is generally achieved by welding or using a special form of a clamp. In the connection with an I-shaped steel beam, the direct welding method is a secondary welding operation when the I-shaped steel beam is in a stressed state, which has a certain adverse effect on the stress performance and state of the I-shaped steel beam. In the connection using a special form of a clamp, the existing connection structure node has the following adverse effects: the size of the connection part is large, the size needs to be customized according to the size of the I-shaped steel beam plate, the I-shaped steel beam needs to be perforated, and the I-shaped steel beam is subjected to eccentric torsion. SUMMARY

[0003] The present application aims to provide a hanger rod and I-shaped steel beam lower flange connection node which is light and small, has strong versatility, and is easy to install, and the connection hanger rod does not have an adverse effect on the eccentric torsion of the original I-shaped steel beam.

[0004] The present application is achieved by the following measures: an asymmetric U-shaped clamping groove is clamped on one side of the lower flange of an I-shaped steel beam, fixed with the I-shaped steel beam by tightening a fixing bolt, a nut is arranged at the upper end of the hanger rod, and the nut is passed through the slot before the U-shaped clamping groove is installed, the hanger rod is centered with the web of the I-shaped steel beam by moving horizontally, and the hanger rod is fixed with the U-shaped clamping groove by tightening the nut.

[0005] The asymmetric U-shaped clamping groove is an open thin-walled member, the side edge is turned up, the thickness of the clamping groove is greater than the thickness of the lower flange of the I-shaped steel beam, the short limb is located above the lower flange of the I-shaped steel beam and has a length less than the width of one side of the lower flange of the I-shaped steel beam, and full-thread bolt holes are arranged in the middle region; the long limb is located below the lower flange of the I-shaped steel beam and has a length greater than half the width of the lower flange of the I-shaped steel beam, a slot is arranged in the middle region, and the slot covers the centering region of the web of the I-shaped steel beam.

[0006] The fixing bolt corresponds to the full-thread bolt hole in the middle region of the short limb of the U-shaped clamping groove in terms of specification, and the fixing bolt is fixed with the I-shaped steel beam by being tightened.

[0007] The upper end of the suspender is provided with a nut, which passes through the slot of the middle region of the long limb of the U-shaped clamping groove, and the centering of the suspender and the web of the I-shaped steel beam is realized by moving the suspender horizontally, and the suspender and the U-shaped clamping groove are fixed by tightening the fixing nut after the centering of the suspender and the web of the I-shaped steel beam.

[0008] Compared with the prior art, the beneficial effects of the node are that the connecting piece has good versatility, can be moved longitudinally along the I-shaped steel beam, has certain adjustability for different widths and thicknesses of the lower flange of the I-shaped steel beam, can be centered with the web of the I-shaped steel beam transversely, and the suspender load will not cause eccentric torsion of the I-shaped steel beam. The connection between the U-shaped clamping groove and the I-shaped steel beam is realized by tightening the fixing bolt to achieve friction connection, without the need to open holes in the web or flange of the I-shaped steel beam, and direct welding connection with the I-shaped steel beam is also avoided, which will not adversely affect the stress performance and state of the I-shaped steel beam.
