Description

Technical Field

[0001] This utility model belongs to the field of prefabricated steel structure technology, and in particular relates to a connection structure between the bottom of a steel H-beam and a box column. Background Technology

[0002] In prefabricated steel structure residential buildings, the connection between box columns and steel beams is frequently involved. The traditional method of column-beam connection is to add a transverse diaphragm inside the box column. There are two types of transverse diaphragms: the first is the column-integrated type, where the transverse diaphragm has an opening in the middle and is located inside the box column; the second is the through type, where the transverse diaphragm has an opening in the middle and extends out of the box column after being cut off at all four sides. In the first type, the steel beam is welded to the outer surface of the box column, and the welding position corresponds to the transverse diaphragm. In the second type, the steel beam is welded to the transverse diaphragm, and in some cases, a square tube sleeve is installed on the surface of the box column, which is then fixed to the H-beam, making installation and construction more convenient.

[0003] The H-beam and the box column are fixed together by welding the web. However, the lack of a connection structure between the bottom of the steel beam and the box column leaves the bottom of the steel beam suspended, resulting in insufficient support. Therefore, a connection structure between the bottom of the H-beam and the box column is needed to provide stable support between them, thereby increasing the support capacity of the H-beam and improving the stability of the connection between the H-beam and the box column.

This allows the I-beam to connect the H-beam and the box column, thus achieving stable support between the bottom of the H-beam and the box column, thereby increasing the supporting force on the H-beam and improving the stability of the connection between the H-beam and the box column.

[0012] 2. By setting an elastic washer, this utility model increases the friction on the surface of the nut block, preventing the nut block from loosening and falling off due to external vibration, thereby improving the stability of the nut block installation.

[0013] 3. This utility model uses the combination of a limiting slider and a sliding groove to limit and guide the movement of the locking block, avoiding the locking block from shaking during the rotation of the threaded rod, thereby improving the convenience of locking and aligning the locking block with the I-beam.
