[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figure 1-6 A modular steel frame structure includes columns 1, beams 2, and connecting plates 3. The columns are vertically arranged, and the beams are horizontally arranged between adjacent columns. The outer walls of the beam-column connection and the column-column connection are smoothly transitioned. The connecting plates are arranged on the inner side of the column-beam connection to form a frame unit with the column-beam. End plates 4 are provided at both ends of the columns. At least one connecting hole 41 is provided on the end plate, and the upper and lower columns are connected through the connecting hole by a bolt-like connector.

[0020] The column described in this embodiment is formed by bending a steel plate to create a structure with a first folded edge 11, a second folded edge 12, and a non-closed rectangle 13. That is, the internal shape of the column is rectangular, and the two ends of the crossbeam are overlapped and fixed on the first folded edge and the second folded edge.

[0021] The crossbeam described in this embodiment is made of channel steel.

[0022] In this embodiment, the shape of the end plate matches the hollow shape of the column, and it is welded and fixed to the column to form the closed end of the column.

[0023] In this embodiment, a reinforcing plate 5 is installed inside the rectangular column to strengthen the column.

[0024] See Figure 3 In this embodiment, the connecting plate 3 is formed by bending a steel plate into an L-shape. The bent edge 31 is attached to and fixedly connected with the bent edge of the column, or see [other details]. Figure 4 It is bent into a U-shaped plate, and the bent edge 31' is attached and fixedly connected to the folded edge of the column. The connecting plate can be fixed on the folded edge of a single column to replace the function of the reinforcing plate.

[0025] In this embodiment, multiple first bolt holes 14 are provided on the first and second folded edges, and second bolt holes and third bolt holes that cooperate with the first bolt holes are provided on the edge of the channel steel and the bent edge of the connecting plate.
