[0001] This utility model relates to the field of prefabricated steel structure technology, and in particular to a corner tenon and mortise connection structure for a single truss beam. Background Technology

[0002] Prefabricated construction refers to the process of prefabricating some or all of a building's components in a factory, transporting them to the construction site, and assembling them into a building using reliable connection methods. This construction method transfers a large amount of on-site work from traditional construction methods to the factory, employing standardized design, factory production, prefabricated construction, information management, and intelligent applications, offering advantages such as energy saving, environmental protection, and shorter construction periods.

[0003] During the construction of prefabricated steel structures, truss beams are often set at angles at corners, which brings many operational difficulties, inconveniences and low efficiency to on-site workers. Therefore, there is an urgent need for a truss beam corner connection structure to realize the on-site installation of truss beams. Utility Model Content

[0032] like Figures 1-5 As shown, this embodiment provides a corner tenon and mortise connection structure for a single truss beam, which includes a first fastener 1, a second fastener 2, and a locking assembly 3. The first fastener 1 has a first groove 11, and the second fastener 2 has a second groove 21. When the first fastener 1 and the second fastener 2 are fastened together, the first groove 11 and the second groove 21 are interconnected and form a connecting channel 111. The connecting channel 111 is configured to be sleeved on the chord 100. One end of the connecting channel 111 extends along a first direction, and the other end extends along a second direction. The first direction and the second direction are set at an angle. The locking assembly 3 can lock the first fastener 1 and the second fastener 2 together.

[0033] In this embodiment, the first fastener 1 has a first groove 11, and the second fastener 2 has a second groove 21. When the first fastener 1 and the second fastener 2 are fastened together, the first groove 11 and the second groove 21 are interconnected and form a connecting channel 111. The connecting channel 111 can be fitted onto the chord 100 to facilitate the on-site installation of the chord 100. One end of the connecting channel 111 extends along a first direction, and the other end extends along a second direction. The first direction and the second direction are set at an angle, so that the corner tenon and tenon connection structure of the single truss beam can fit tightly against the corner of the truss beam, improving the stability and reliability of the connection. The locking component 3 can lock the first fastener 1 and the second fastener 2 together, further improving the overall structural stability. Through the above settings, the corner tenon and tenon connection structure of the single truss beam of this application can simplify the installation work of the truss beam at the corner and improve construction efficiency.

[0034] The following is a detailed explanation of the mortise and tenon joint structure at the corner of a single truss beam:

[0035] Specifically, such as Figures 1-4 As shown, the first fastener 1 is provided with a first protrusion 12, and the second fastener 2 is provided with a second protrusion 22. When the first fastener 1 and the second fastener 2 are fastened together, the first protrusion 12 and the second protrusion 22 abut against each other and form a connecting protrusion 121. The locking component 3 is provided on the connecting protrusion 121 so that the first fastener 1 and the second fastener 2 can be locked together by the cooperation of the locking component 3 and the connecting protrusion 121.

[0036] More specifically, such as Figure 4 As shown, the first protrusion 12 is disposed on both sides of the opening end of the first groove 11, and the second protrusion 22 is disposed on both sides of the opening end of the second groove 21. This effectively prevents the first fastener 1 and the second fastener 2 from misaligning or slipping during the fastening process, thereby ensuring the accuracy and firmness of the connection. Moreover, this arrangement ensures that both sides of the opening ends of the first groove 11 and the second groove 21 can achieve a locking effect with the locking component 3, preventing the connecting channel 111 from opening due to external force.

[0037] Specifically, such as Figures 1-4 As shown, the locking component 3 includes a first locking member 31, which has a first slot 311 that slides with the connecting protrusion 121. The connecting protrusion 121 abuts against the inner wall of the first slot 311, ensuring a tight connection between the first fastener 1 and the second fastener 2, and is also easy to operate and more efficient.

[0038] More specifically, in this embodiment, both the first protrusion 12 and the second protrusion 22 are L-shaped protrusions. The end of the L-shaped protrusion facing away from the first fastener 1 and the second fastener 2 is spaced apart from the first fastener 1 and the second fastener 2, so that the connecting protrusion 121 formed by the first protrusion 12 and the second protrusion 22 can extend into the first slot 311 to achieve mutual locking of the first fastener 1 and the second fastener 2. Furthermore, as... Figure 3 and Figure 4 As shown, the first locking member 31 is a plate-shaped structure, and the first slot 311 is formed on the plate-shaped structure. When the first fastener 1 and the second fastener 2 are engaged with each other, the first protrusion 12 and the second protrusion 22 abut against each other and form a T-shaped connecting protrusion 121, so that the first slot 311 and the connecting protrusion 121 can slide together. In other embodiments, the first locking member 31 adopts a block-shaped structure, as long as the above-mentioned functions can be achieved, and the specific structure of the first locking member 31 is not limited here.

[0039] Specifically, such as Figures 1-5 As shown, there are two first locking members 31. One first locking member 31 is slidably connected to the connecting protrusion 121 along the first direction, and the other first locking member 31 is slidably connected to the connecting protrusion 121 along the second direction. This allows the two first locking members 31 to be slidably connected to the connecting protrusion 121 along two different directions, thereby achieving bidirectional locking of the first fastener 1 and the second fastener 2, which enhances the stability and reliability of the overall structure under complex stress conditions.

[0040] More specifically, such as Figures 1-4 As shown, the locking assembly 3 also includes a first bolt 32 and a first nut 33. The first locking member 31 is provided with a first ear plate 312. When the two first locking members 31 are slidably connected to the connecting protrusion 121 in two different directions, one end of the two first locking members 31 can abut against each other. The first bolt 32 can pass through the two first ear plates 312 and be threadedly connected to the first nut 33, thereby locking the two first locking members 31 against each other and preventing the two first locking members 31 from disengaging from the connecting protrusion 121 in the first direction and the second direction, thereby strengthening the stability of the overall structure and making the locking effect of the second fastener 2 of the first fastener 1 better.

[0041] More specifically, in this embodiment, a first locking member 31 is provided with two first ear plates 312. Among the two first locking members 31, the first ear plate 312 on one of the first locking members 31 can extend between the two first ear plates 312 on the other first locking member 31. The first bolt 32 passes through the four first ear plates 312 and is threaded onto the first nut 33, so that the two first locking members 31 cannot be separated from each other, thereby improving the locking effect of the first fastener 1 and the second fastener 2.

[0042] Specifically, such as Figures 1-4 As shown, the locking assembly 3 also includes a second locking member 34. The second locking member 34 is provided with a second slot 341 that slides with the connecting protrusion 121. The connecting protrusion 121 abuts against the inner wall of the second slot 341, ensuring a tight connection between the first fastener 1 and the second fastener 2, and is also easy to operate and more efficient.

[0043] More specifically, such as Figures 1-4 As shown, in this embodiment, the first locking member 31 and the second locking member 34 are respectively disposed on opposite ends of the connecting protrusion 121 to ensure that the connecting protrusion 121 achieves a locking effect with the locking assembly 3 on both the inner and outer sides of the corner of the truss beam. Furthermore, in this embodiment, the second locking member 34 is a plate-like structure with a second slot 341, facilitating the sliding connection of the second locking member 34 to the connecting protrusion 121 by the operator. In other embodiments, the second locking member 34 is a block-like structure. The specific structure of the second locking member 34 is not limited here, as long as it achieves the aforementioned functional purpose.

[0044] Specifically, such as Figures 1-4 As shown, there are two second locking members 34. One second locking member 34 is slidably connected to the connecting protrusion 121 along the first direction, and the other second locking member 34 is slidably connected to the connecting protrusion 121 along the second direction. This allows the two second locking members 34 to be slidably connected to the connecting protrusion 121 along two different directions, thereby achieving bidirectional locking of the first fastener 1 and the second fastener 2, which enhances the stability and reliability of the overall structure under complex stress conditions.

[0045] More specifically, such as Figure 1 and Figure 2 As shown, the locking assembly 3 also includes a second bolt 35 and a second nut 36. The second locking member 34 is provided with a second ear plate 342. When the second ear plates 342 of the two second locking members 34 abut against each other, the second bolt 35 can pass through the two second ear plates 342 and be threaded to the second nut 36, so that the two second locking members 34 can form a more solid connection, preventing the two second locking members 34 from detaching from the connecting protrusion 121 from the first direction and the second direction respectively, thereby improving the stability of the overall structure.

[0046] Specifically, such as Figures 1-4 As shown, the first fastener 1 and / or the second fastener 2 are provided with a connecting part 13, which extends along a third direction and is configured to connect to the column 200. The third direction is perpendicular to the first direction and the second direction. This arrangement enables the first fastener 1 and / or the second fastener 2 to be connected to the column 200 in the third direction to meet the on-site installation requirements of the truss beam.

[0047] More specifically, in this embodiment, the connecting part 13 is a square sleeve with a cavity for the column 200 to pass through. The square sleeve has multiple connecting holes spaced apart along its circumference. Bolts pass through these connecting holes and the column 200, and are threaded onto a nut, thus achieving a tight connection between the connecting part 13 and the column 200. In other embodiments, the connecting part 13 is a circular cylinder; any design that facilitates the installation of the column 200 is acceptable, and the specific structure of the connecting part 13 is not limited here.

[0048] It should be noted that in this embodiment, the first and second directions are both horizontal, while the third direction is vertical, to facilitate the on-site installation of the truss beam. In other embodiments, the above directions may be adjusted according to the actual construction work, which will not be discussed in detail here.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
