[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Please see Figure 1-2 The present invention provides a technical solution: a prefabricated steel structure beam-column joint tenon and mortise connection structure, including a first pressing component and a second pressing component, wherein the first pressing component is installed on the upper end of the column-type tenon and mortise component, and the second pressing component is installed on one side of the column-type tenon and mortise component.

[0021] In this invention, the first pressing assembly includes a first pressing ball 1, a first connecting post 2, an upper fixing plate 3, a lower fixing plate 4, and a first pressing plate 5. One end of the first connecting post 2 is connected to the first pressing ball 1, and the other end of the first connecting post 2 passes through the upper fixing plate 3 and the lower fixing plate 4 respectively and is fixed to the connecting seat 6. The first pressing plate 5 is fixedly installed on the outer wall of the first connecting post 2 and is disposed between the upper fixing plate 3 and the lower fixing plate 4. It also includes a first compression spring 7, which is sleeved on the outside of the first connecting post 2 and is located between the first pressing plate 5 and the lower fixing plate 4.

[0022] In this invention, the second pressing assembly includes a second connecting post 8, a second pressing plate 9, a second pressing ball 10, and an insert post 11. The second connecting post 8 is perpendicular to the first connecting post 2. One end of the second connecting post 8 is connected to the second pressing ball 10. The second pressing plate 9 is installed outside the second connecting post 8, and the other end of the second connecting post 8 is connected to the insert post 11. The assembly also includes a second compression spring 12, which is installed outside the second connecting post 8 and is located between the second pressing plate 9 and the insert post 11.

[0023] Working principle: The beam-type mortise and tenon component enters the column-type mortise and tenon component. Pressing the first pressing ball causes the first connecting column to move down, which in turn causes the connecting seat to move down. The connecting seat is inserted into the insertion hole in the beam-type mortise and tenon component, and a groove is formed between the lower fixing plate and the connecting seat. Then, pressing the second pressing ball causes the second connecting column to move, which in turn causes the insertion column to move. The insertion column is then inserted into the groove for fixation.

[0024] In summary, the present invention has a novel structural design that combines prefabricated connections and mortise and tenon connections, which can improve the firmness of the connection between column-type mortise and tenon components and beam-type mortise and tenon components. It can make construction more convenient and simple, and greatly reduce the difficulty of disassembly. It can also allow the steel structure to be reused or recycled.
