[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] See also Figures 1 to 4 As shown, this embodiment provides a connection structure between an integrated steel and a crossbeam, which includes an interface 1 arranged on the integrated steel, a tenon 2 arranged at the end of the crossbeam, and a brake iron 3.

[0028] The end edge of the tenon 2 extends beyond the side wall of the tenon 2 to form a limiting edge 21 . Specifically, the tenon 2 includes an I-beam 22 welded to the crossbeam, and an end plate 23 is provided at the end of the I-beam 22 . The edge of the end plate 23 forms the limiting edge 21 .

[0029] An installation cavity is formed on the interface 1, and two wedge blocks 11 are respectively arranged on both sides of the installation cavity. Specifically, the interface 1 includes a bottom plate 12 and a side plate 13 welded on the integrated steel. The installation cavity is enclosed by the bottom plate 12 and the two side plates 13, and the wedge blocks 11 are fixed on the inner walls of the side plates 13.

[0030] The two wedge blocks 11 are arranged at intervals to form a mounting gap 14 that gradually narrows from top to bottom. The tenon 2 is placed into the mounting cavity from top to embed the limit edge 21 into the mounting gap 14 to complete the pre-connection. Afterwards, the brake iron 3 is inserted into the gap between the limit edge 21 and the mounting gap 14, and the limit edge 21 is tightened. The brake iron 3 and the bevel of the wedge block 11 have the same inclination angle, preferably 70° to 80°.

[0031] In particular, a notch 15 is provided on the bottom plate 12 opposite to the installation seam 14 for observing the assembly status and for conveniently ejecting the brake iron 3 and the tenon 2 during disassembly.

[0032] The cooperation between the brake iron 3 and the wedge block 11 can fully reduce the assembly gap, limit the lateral displacement of the beam, and improve the assembly effect. However, there is still a risk of vertical movement of the beam. Therefore, after the brake iron 3 is inserted, a locking bolt 4 is passed across the two side plates 13. The locking bolt 4 is located above the tenon 2 to upper limit the tenon 2, thereby fully ensuring the connection reliability.

[0033] In this regard, the present embodiment further provides a method for connecting an integrated steel and a crossbeam, comprising the following steps:

[0034] 1) Before leaving the factory, weld the interface 1 on the integrated steel and weld the tenon 2 on the end of the beam;

[0035] 2) During on-site construction, the tenon 2 is placed from above into the installation seam 14 of the interface to complete the pre-assembly;

[0036] 3) Insert the brake iron 3 into the gap of the installation seam 14 to tighten the tenon 2;

[0037] 4) Screw the locking bolt 4 into the interface 1 to lock the tenon 2.

[0038] In summary, the connection structure and connection method of the integrated steel and the beam replace the original connection method of bolt connection and welding, and realize fast and reliable installation on site through splicing and clamping, which reduces the connection gap, eliminates the welding operation, ensures the connection strength, reduces the difficulty of on-site assembly, and provides a new idea for the installation method of the beam.

[0039] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
