Preferably, the first fixing part fixes the steel beam and the steel column through alignment bolts.

More preferably, the first fixing part is also bound and fixed to the rigid beam through a wire rope.

More preferably, the two first fixing parts opposite to each other on the steel column are bound and fixed to the steel column by a wire rope.

Preferably, the first fixing part and the second fixing part are groove structures, including a first side, a second side and a recessed area between the first side and the second side.

Preferably, the steel columns are connected to the rigid beams at equal intervals.

Preferably, the rigid beam is an H-shaped steel beam.

Compared with the prior art, the present invention has the advantages of:

1) The diagonal brace of the present invention is connected with the rigid beam and the steel column to form a triangular steel structure, which is stable in structure, and the connection with the rigid beam and the steel column is a detachable connection, which replaces the welding fixation in the prior art, and realizes the fire-free connection;

2) The present invention uses prestressed tie rods to connect and fix the diagonal braces with steel beams or rigid columns, and skillfully transfers the load of the portal steel frame to the steel columns, further enhancing the stability of the portal frame structure.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Example 1

Referring to Fig. 1 to Fig. 4, the portal frame reinforcement structure of the present embodiment includes: diagonal braces 1, prestressed tension rods 2, rigid beams and a plurality of steel columns 4 connecting steel beams 3 at equal intervals, and the diagonal braces 1 are located at Between the rigid beam and the steel column 4, the diagonal brace 1, the rigid beam and the steel column 4 are connected to each other to form a triangular steel structure; one end of the prestressed tension rod 2 is connected to the prestressed tension rod 2, and the other end is connected to the rigid beam or steel column 4; the rigid beam is preferably H-shaped Steel beam 3.

As shown in Figure 2, the two ends of the brace 1 are provided with first fixing parts for detachably connecting the rigid beam and the steel column 4, and the brace 1 is provided with a plurality of second fixing parts for detachably connecting the prestressed tie rods 2. fixed part. The first fixing part and the second fixing part are configured as a groove structure, including a first side, a second side and a recessed area between the first side and the second side. During installation, the first fixing part is sheathed on the steel beam 3 or the rigid column, and its recessed area contacts the connected rigid beam and/or steel column 4 .

Further, the first fixing part connects and fixes the rigid beam and the steel column 4 through alignment bolts. At the same time, the steel wire rope 5 is also used to bind the first fixing part and the rigid beam, and the binding position of the steel wire rope 5 is clamped and fixed by an electric hardware fastener 51, and its connection structure is shown in FIG. 3 . When a rigid column is connected with two diagonal braces 1 at the same time, and the first fixing parts of the two diagonal braces 1 are arranged opposite to each other, the steel wire rope 5 is also used to bind the first fixing part and the rigid column. The connection structure is shown in Figure 4 shown.

Example 2

As shown in Figure 5, the difference between the portal frame reinforcement structure of this embodiment and Embodiment 1 is that two steel beams 3 with different horizontal heights are connected and fixed on the steel column 4; The first fixed part is fixed on the steel column 4 through alignment bolts, and the steel wire rope 5 is used to bind and fix the first fixed part with the rigid column. Other structures are the same as those in Embodiment 1, and will not be repeated here.
