Description

Technical Field

[0001] The utility model relates to the technical field of steel structure beam-column connection, in particular to a mortise and tenon type steel structure beam-column connection node. Background Art

[0002] At present, high-strength bolt connection, welding or bolt-welding hybrid connection is commonly used for prefabricated steel structure beam-column node connection. For fully welded connection where both flange and web are welded, and bolt-welding hybrid connection where upper and lower flanges are welded and web is connected with high-strength bolts, since it is necessary to install before welding during construction, it is easy to generate large welding residual stress, which affects the mechanical performance of the node. In addition, welding will damage the paint coating of the steel structure and need to be repainted.

[0003] Traditional steel structure main beam connection nodes use welding and bolt connection methods, which have problems such as too many bolt holes and bolts and complicated welding methods. This leads to cumbersome overall production and installation steps, and the construction speed is slow due to drilling holes and tightening bolts, which is not conducive to construction operations.

[0004] Therefore, in view of the above problems, a mortise and tenon type steel structure beam-column connection node is proposed to solve the above problems. Utility Model Content

The utility model is plug-in installed, has a simple structure and is easy to install, and at the same time improves the efficiency of steel structure beam-column installation.

[0006] The technical solution of the utility model to solve the technical problem is as follows: the utility model provides a mortise and tenon type steel structure beam-column connection node, including a top plate, a tenon and a mortise sleeve, the mortise sleeve has a "U"-shaped cross-section, including a connecting plate, two plug-in plates and two connecting frames, one end of the two connecting frames is vertically provided with a plug-in plate 1, the other ends of the two connecting frames are connected through a connecting plate 1, a cavity 1 is provided in the two connecting frames, and a cavity 2 for plugging in the tenon is formed between the two connecting frames along the vertical direction, and a cavity 3 for plugging in the top plate is provided in the tenon.

[0009] As an optimization, the top plate includes a plug-in plate three, a connecting plate and a top plate body. Four connecting plates are arranged at the bottom of the top plate body, and a plug-in plate three is arranged above the end of the top plate body. The width of the plug-in plate three is the same as the spacing between the two plug-in plates one. When the top plate is plugged into the tenon, the top of the plug-in plate three is flush with the top of the plug-in plate one, and the connecting plates are respectively in contact with the inner walls of the cavity three of the tenon.

[0010] As an optimization, a connection hole one is opened on the connection frame, a connection hole two is opened on the tenon, and a connection hole three is opened on the connection plate.

[0023] like Figures 1 to 5As shown, a mortise and tenon type steel structure beam-column connection node includes a top plate 1, a tenon 2 and a mortise sleeve 3. The mortise sleeve 3 has a "U"-shaped cross-section and includes a connecting plate 32, two plug-in plates 33 and two connecting frames 31. A plug-in plate 33 is vertically arranged at one end of each of the two connecting frames 31. The other ends of the two connecting frames 31 are connected via a connecting plate 32. A cavity 34 is arranged in the two connecting frames 31, and a cavity 35 for inserting the tenon 2 is formed between the two connecting frames 31 along the vertical direction. A cavity 21 for inserting the top plate 1 is arranged in the tenon 2.

[0024] In this example, the top of the plug board 33 is higher than the top of the connection frame 31.

[0025] In this example, the tenon 2 is arranged at the end of the beam 22, and the width of the mortise 3 is the same as the width of the end of the beam 22. When the tenon 2 and the mortise 3 are plugged in, the top of the plug-in plate 33 is flush with the top of the beam 22.

[0026] In this example, the top plate 1 includes a plug-in board 3 11, a connecting board 12 and a top plate body 13. Four connecting boards 12 are arranged at the bottom of the top plate body 13, and a plug-in board 3 11 is arranged above the end of the top plate body 13. The width of the plug-in board 3 11 is the same as the spacing between two plug-in boards 1 33. When the top plate 1 is plugged into the tenon 2, the top of the plug-in board 3 11 is flush with the top of the plug-in board 1 33, and the connecting boards 12 are respectively in contact with the inner walls of the cavity 3 21 of the tenon 2.

[0027] In this example, a connection hole 1 311 is formed on the connection frame 31, a connection hole 23 is formed on the tenon 2, and a connection hole 3 121 is formed on the connection plate 12. The positions of the connection hole 1 311, the connection hole 23 and the connection hole 3 121 are adapted to each other.

[0028] In this example, the connection node also includes bolts 4 and nuts 5 for fixing the connection hole 1 311 , the connection hole 23 , and the connection hole 3 121 .

[0029] In this example, a rib plate 14 is provided between the plug board 3 11 and the top plate body 13. The rib plate 14 enhances the stability of the structure.

[0030] Working process:

[0031] (1) Beam-column installation: The tenon 2 on one side of the beam 22 is positioned and plugged into the mortise sleeve 3 through the cavity 2 35. The tenon 2 and the mortise sleeve 3 are nested in an inverted trapezoidal structure. The "dovetail tenon" structure makes the connection stable, achieving a stable bite between the two components.

[0032] (2) Top plate installation: The plug-in board 3 11 of the top plate 1 is inserted between the two plug-in boards 1 33 for positioning, and the bottom connecting board 12 is inserted into the cavity 3 21 of the tenon 2.

[0033] (3) Bolt installation: The bolt 4 is inserted into the connection hole 1 311 of the mortise 3, the connection hole 23 of the tenon 2, and the connection hole 3 121 of the top plate 1 in sequence, and then tightened with the nut 5. After the final tightening is completed, the connection gap between the top plate 1 and the mortise 3 is welded to complete the installation.

[0034] The combined plug-in installation of the beam 22 is achieved by adopting the tenon 2 and the mortise 3. The "dovetail tenon" structure makes the connection stable, the structure is simple and the installation is convenient, which reduces the problems of excessive number of bolts and excessive holes in the steel plate during the installation of traditional beams and columns, innovates the connection structure of steel structure beams and columns, and improves the efficiency of steel structure beam and column installation.

[0035] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
