Description

Technical Field

[0001] The utility model relates to the technical field of beam-column assembly, in particular to an assembled steel structure beam-column. Background Art

[0002] Existing connections between beams and columns are usually welded, bolted, or indirectly connected through angle steel. However, when the other end of the beam is subjected to a large force, the connecting end of the beam is subjected to a large torque. If it is only connected by bolts or welding, there is often a possibility of breakage, and the strength needs to be improved. Utility Model Content

[0003] The purpose of the present invention is to provide a prefabricated steel structure beam-column to solve the problem of poor torsional resistance at the beam-column connection mentioned in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled steel structure beam column, comprising a column and a beam, both of which are H-shaped steels, a connecting plate fixedly connected to each other on the two notch sides of the column, a protrusion is provided on one side of the two connecting plates close to each other, and two grooves are formed between the protrusions, the two sides of the notch of the column are respectively inserted into the grooves, the end of the beam is fitted with the column, the protrusions at both ends of the connecting plate are inserted into the notch of the beam and fixed thereto, and the upper and lower widths of the connecting plate are equal to the width of the notch of the beam.

[0005] Preferably, the upright posts and the connecting pieces are fixed by bolts, and the two ends of the connecting pieces and the crossbeams are fixed by bolts.

[0006] Preferably, the connection points of the upright column, the connecting plate and the crossbeam are all provided with a socket, and a sleeve is inserted into the socket, and a bolt is inserted into the sleeve.

[0007] Preferably, the protruding length of both ends of the connecting piece relative to the pillar is 10-20 cm.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The utility model provides an assembled steel structure beam-column, which fixes the crossbeam by connecting plates at both ends. The connecting plates are stronger than traditional bolts, and can enable the connection between the crossbeam and the column to withstand greater torque, thereby preventing the connection from breaking.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-4 The cam 6 of the present invention is a kind of H-shaped steel structure, and the cam 6 of the present invention is a kind of H-shaped steel structure.

[0017] Specifically, the column 1 and the connecting piece 3 are fixed together by bolts 4, and the ends of the connecting piece 3 are fixed to the crossbeam 2 by bolts 4. This connection facilitates installation and removal. The connection points of the column 1, the connecting piece 3 and the crossbeam 2 are all provided with sockets 8, and the sockets 8 are inserted into the sockets 8. The bolts 4 are inserted into the sleeves 7. Together, the sleeves 7 and the bolts 4 can improve the shear resistance. At the same time, when the bolts 4 are twisted, the smooth outer wall of the sleeves 7 makes it easy to remove them together.

[0018] The protruding length of both ends of the connecting piece 3 relative to the column 1 is 10-20 cm. The protruding length of the connecting piece 3 should not be too long, otherwise the bending resistance effect will be poor, nor too short, otherwise the connection with the beam 2 will not be sufficient.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
