[0002] A pitched roof refers to a roof with a slope greater than 3% (as defined in Article 2.0.1 of the "Technical Specification for Pitched Roof Engineering" GB 50693-2011). During the construction of the ridge of a pitched roof, the beam and column structures are often connected by welding, a method that is time-consuming, labor-intensive, and results in low connection accuracy. Errors in this process necessitate rework, reducing efficiency and hindering cost savings.

[0003] Therefore, there is an urgent need for a connection node to enable the assembly of beam and column structures. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a mortise and tenon joint connection node for a ridge beam-column cross-beam of a pitched roof, which includes a central member 1, a first connector 2, and a second connector 3. The end of the central member 1 is configured to connect to the column structure 100. Multiple first connectors 2 are provided, spaced apart circumferentially along the central member 1. The first connectors 2 extend radially along the central member 1. One end of each first connector 2 is connected to the central member 1, and the other end is configured to connect to a first beam 200. A second connector 3 is disposed between two adjacent first connectors 2. One end of each second connector 3 is connected to the central member 1, and the other end is configured to connect to a second beam 300. The second beam 300 is rotatable relative to the second connector 3 about a rotation axis.

[0031] In this embodiment, the end of the central component 1 can be directly connected to the column structure 100, simplifying the assembly process between the column structure 100 and the connection node. Multiple first connecting components 2 are spaced apart circumferentially along the central component 1 to meet the design requirements of different pitched roof ridges. One end of each first connecting component 2 is connected to the central component 1, and the other end is configured to connect to the first beam 200, thus meeting the connection requirements of the first beam 200. A second connecting component 3 is disposed between two adjacent first connecting components 2. One end of the second connecting component 3 is connected to the central component 1, and the other end is configured to connect to the second beam 300. The second beam 300 can rotate relative to the second connecting component 3 around a rotation axis, thereby adjusting the rotation angle of the second beam 300 relative to the second connecting component 3, thus meeting the installation requirements of the second beam 300 to adapt to different pitched roof ridge designs. Through the above configuration, the mortise and tenon joint connection node of the pitched roof ridge cross ridge beam-column in this embodiment can efficiently and accurately realize the assembly operation of the beam and column structure, saving construction costs.

[0032] It should be noted that in this embodiment, the central component 1 extends vertically, and its bottom end can be directly connected to the column structure 100. The axis of rotation of the second beam 300 relative to the second connecting component 3 is horizontal. In other embodiments, the central component 1 can extend horizontally, with one end connected to the column structure 100, and the second beam 300 can rotate vertically relative to the second connecting component 3. That is, the specific arrangement of the above components can be adjusted according to the design of different pitched roof ridges, and is not limited here.

[0033] The following is a detailed explanation of the mortise and tenon joint connection between the beam and column at the intersection of the ridge line of a pitched roof:

[0034] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, one end of the central component 1 has a square structure, and the column structure 100 is inserted into the square structure and fixed by bolts, thereby realizing the rapid assembly of the column structure 100 and the central component 1. In other embodiments, one end of the central component 1 can be set as a circular structure, as long as it can adapt to the cross-sectional shape of the column structure 100, and no further limitations are imposed here.

[0035] More specifically, such as Figure 1 and Figure 2 As shown, the central component 1 has multiple first connecting holes 11 spaced apart along its circumference. The column structure 100 is inserted into the central component 1, and bolts pass through the first connecting holes 11 and are connected to the column structure 100. This allows the column structure 100 to be connected to the central component 1 through the first connecting holes 11, which can distribute the force at the connection point and thus enhance the stability of the entire connection node. It can be understood that when the column structure 100 is inserted into the central component 1, the bolts passing through the first connecting holes 11 and screwed to the column structure 100 can achieve a stable connection between the column structure 100 and the central component 1.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the first beam 200 is height-adjustably connected to the first connector 2, allowing construction workers to precisely adjust the position of the first beam 200 according to the actual tilt angle and height changes of the pitched roof, thereby adapting to the design requirements of different pitched roofs.

[0037] More specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the first connecting member 2 is provided with a second connecting hole 21, which extends vertically. The first beam 200 is connected to the first connecting member 2 through the second connecting hole 21, thereby achieving height adjustment of the first beam 200. It can be understood that by inserting bolts through the second connecting hole 21 and screwing them onto the first beam 200, a stable connection between the first beam 200 and the first connecting member 2 can be achieved. When construction personnel need to adjust the height of the first beam 200 relative to the first connecting member 2, they first loosen the bolts, then slide the bolts vertically to adjust their height position in the second connecting hole 21, and then tighten the bolts again so that they abut against both sides of the opening of the second connecting hole 21, thereby locking the first beam 200 onto the first connecting member 2 and fixing the first beam 200 at a preset height.

[0038] More specifically, in other embodiments, the first connecting member 2 has multiple through holes along the vertical direction, and a bolt passes through one of the through holes and is connected to the first beam 200. By adjusting the position of the through hole through which the bolt passes, the height of the first beam 200 can be adjusted. It is understood that those skilled in the art know how to achieve height adjustment of the first beam 200, and therefore the specific technical means will not be described in detail here.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the first connector 2 has a first groove 22, and the first beam 200 is inserted into the first groove 22, thereby achieving precise alignment between the first beam 200 and the first connector 2, which helps to reduce installation errors and improve the stability of the overall structure. Furthermore, bolts can be inserted through the first groove 22 and the first beam 200 to increase the connection strength between them.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the mortise and tenon joint between the beam and column at the intersection of the ridge lines of the pitched roof also includes a third connector 4. The third connector 4 is rotatably connected to the second connector 3 and has a second groove 41. The second beam 300 is inserted into the second groove 41, so that the second beam 300 can be stably connected to the third connector 4. Construction workers can adjust the angle of the second beam 300 relative to the second connector 3 by rotating the third connector 4. Through the above settings, the connection joint can better adapt to the design requirements of different pitched roof ridges, ensuring that the beam structure can be installed according to the predetermined tilt angle and layout.

[0041] More specifically, such as Figure 1 and Figure 2As shown, the end of the third connector 4 furthest from the second beam 300 is hinged to the second connector 3, thus simplifying the installation process and enabling construction workers to complete the assembly and adjustment of the connection nodes more quickly. At the same time, the relatively intuitive and simple adjustment process also improves the accuracy and efficiency of the construction.

[0042] More specifically, such as Figure 1 and Figure 2 As shown, the third connector 4 is provided with two connecting plates 42, which are parallel to each other and spaced apart, and are rotatably connected to the second connector 3. The second connector 3 is disposed between the two connecting plates 42, thus providing a stable support surface for the rotatable connection and ensuring the stability of the third connector 4 when rotating relative to the second connector 3. The second connector 3 adopts a plate-like or block-like structure to facilitate its stable insertion between the two connecting plates 42 and achieve rotatable engagement.

[0043] Specifically, the third connecting member 4 includes two interlocking and detachably connected buckle plates. When the two buckle plates are interlocked, they form a second groove 41 to facilitate the insertion of the second beam 300. When the second beam 300 is inserted into the second groove 41, bolts are passed through the buckle plates and the second beam 300 and screwed onto nuts, achieving a stable connection between the second beam 300 and the third connecting member 4. This also facilitates disassembly and maintenance, making it more convenient. Furthermore, a connecting plate 42 is provided on the buckle plates and has openings. When the two buckle plates are interlocked, pins pass through the corresponding openings on the two connecting plates 42 and the second connecting member 3, allowing the third connecting member 4 to be rotatably connected to the second connecting member 3. This, in turn, enables the second beam 300 to rotate relative to the center member 1 around the rotation axis.

[0044] Specifically, such as Figure 1 and Figure 2 As shown, the extension direction of the first connector 2 is set at an angle to the extension direction of the second connector 3 to meet the installation requirements of the first beam 200 and the second beam 300 and ensure the stress performance of the connection node.

[0045] It should be noted that in this embodiment, the central component 1, the first connecting component 2, and the third connecting component 4 can all be made of square steel pipes, which is not only convenient for obtaining materials locally but also easy to process. In other embodiments, the above components can also be made of round steel pipes. The specific structure and material of the above components are not limited here, as long as they can achieve the above functions. Furthermore, during the installation process, anti-loosening washers are provided at the bolt and nut connections to improve the stability of the components during connection.

[0046] 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.
