[0002] In traditional construction, building components are typically built piecemeal on-site. However, in prefabricated construction, building components such as wall panels, floor slabs, and roofs are prefabricated in a factory environment. These prefabricated components are produced under strict quality control conditions, then transported to the construction site and assembled together using efficient connection methods.

[0003] For pitched roof building structures, the ends of each sloping beam are erected on the beam or column to form a connection node. However, since the included angles between each sloping beam are different, the construction difficulty of the connection node is increased, making it unsuitable for different pitched roof building structures.

[0004] Therefore, there is an urgent need for a sloping beam connection node to solve the above-mentioned technical problems. Utility Model Content

[0031] like Figures 1-3As shown, this embodiment provides a mortise and tenon joint for a sloping roof eaves beam, which includes a support frame 1, a first connector 2, and a second connector 3. The first connector 2 is sleeved on the support frame 1 along a first direction and can rotate relative to the support frame 1 about the first direction. A first connecting part 21 is rotatably provided on the first connector 2. The first connecting part 21 is configured to connect to the first sloping beam 100 and can adjust the rotation angle of the first sloping beam 100 relative to the support frame 1. The second connector 3 is detachably provided on the support frame 1, can interfere with the rotation of the first connector 2, and lock the first connector 2 to the support frame 1. A second connecting part 31 is rotatably provided on the second connector 3. The second connecting part 31 is configured to connect to the second sloping beam 200 and can adjust the rotation angle of the second sloping beam 200 relative to the support frame 1.

[0032] In this embodiment, the first connector 2 is sleeved on the support frame 1 along the first direction, allowing the first connector 2 to rotate relative to the support frame 1 and drive the first connecting part 21 and the first inclined beam 100 to adjust their orientation to adapt to the installation of the inclined beam in different extension directions. The second connector 3 is detachably mounted on the support frame 1, interfering with the rotation of the first connector 2 and locking the first connector 2 onto the support frame 1, thereby fixing the rotation angle of the first connecting part 21 and the first inclined beam 100, which helps to improve the stability of the connection node. Moreover, through the detachable installation of the second connector 3, construction personnel can rotate the first connecting part 21 to a suitable angle and fix it, making the operation more convenient and faster. The first connector 2 is rotatably provided with a first connecting part 21 connected to the first inclined beam 100. The first connecting part 21 can adjust the rotation angle of the first inclined beam 100 relative to the support frame 1. The second connector 3 is rotatably provided with a second connecting part 31 connected to the second inclined beam 200. The second connecting part 31 can adjust the rotation angle of the second inclined beam 200 relative to the support frame 1, thereby adapting to the installation of inclined beams with different included angles and meeting the needs of different pitched roof building structures. Through the above settings, the mortise and tenon joint of the pitched roof eaves inclined beam in this embodiment can adapt to the construction of different pitched roof building structures, and the operation is efficient and convenient.

[0033] The following is a detailed explanation of the mortise and tenon joint connection node of the eaves beam of a pitched roof:

[0034] Specifically, such as Figures 1-3 As shown, the support frame 1 includes a base plate 12 and a support cylinder 13. The base plate 12 serves as the basic load-bearing part of the connection node, which can effectively transfer force and bending moment to other structural components. The support cylinder 13 is disposed on the base plate 12 and extends along the first direction. The first connector 2 is sleeved on the outer peripheral wall of the support cylinder 13, so that the first connector 2 can rotate relative to the support cylinder 13 around the first direction, thereby adjusting the orientation of the first connecting part 21 on the first connector 2 to meet the connection and assembly of the inclined beam.

[0035] It should be noted that the inclined beams include a first inclined beam 100, a second inclined beam 200, and a third inclined beam, etc. The specific number of the first connecting part 21 and the second connecting part 31 can be set according to the specific number of inclined beams. The specific structure and number of the above components are not limited here, and those skilled in the art can adjust them according to the actual working conditions. Moreover, the first direction includes a vertical direction or an inclined direction at an angle to the horizontal plane, which can be adjusted according to the construction conditions, and will not be described in detail here.

[0036] Specifically, such as Figures 1-3 As shown, the first connector 2 is provided with two first ear plates 22, which are parallel to each other and spaced apart. The first connecting part 21 is rotatably disposed between the two first ear plates 22, which not only provides stable support for the first connecting part 21, but also ensures the stability of the first connecting part 21 during rotation.

[0037] More specifically, such as Figures 1-3 As shown, the mortise and tenon connection node of the sloping roof eaves beam also includes a first bolt and a first nut. A first through hole 221 is provided on the first ear plate 22. The first bolt passes through the first through hole 221 and the first connecting part 21, and is threaded to the first nut, making the connection between the first connecting part 21 and the first ear plate 22 more stable. Through the above settings, the first connecting part 21 is firmly connected to the first connecting member 2, and the construction personnel can adjust the tightness between the first bolt and the first nut, thereby adjusting the rotation angle of the first connecting part 21 relative to the first connecting member 2, so as to adapt to the connection and installation of the first sloping beam 100 in different extension directions, making the operation more convenient and faster.

[0038] Specifically, such as Figure 1 As shown, the first connecting part 21 includes two first cover plates 211. One end of each of the two first cover plates 211 is rotatably connected (e.g., via a pin, hinge, or other connection method) to the first connecting member 2, and the other end can be interlocked and fitted onto the first inclined beam 100. This not only simplifies the installation process but also improves the stability of the connection. When the two first cover plates 211 are interlocked and tightly fitted onto the first inclined beam 100, a stable support groove structure is formed, ensuring that the first inclined beam 100 is inserted into the support groove without loosening or displacement.

[0039] More specifically, one end of the first inclined beam 100 is clamped between two first cover plates 211. A through hole is provided on each first cover plate 211, and bolts are inserted through the through hole and the first inclined beam 100, threaded onto a nut, thus achieving a stable connection between the first cover plate 211 and the first inclined beam 100. Furthermore, this arrangement facilitates the disassembly and assembly of the components by construction personnel, making construction more convenient.

[0040] Specifically, such as Figures 1-3 As shown, the second connector 3 is provided with two second ear plates 32, which are parallel to each other and spaced apart. The second connecting part 31 is rotatably disposed between the two second ear plates 32, which not only provides stable support for the second connecting part 31, but also ensures the stability of the second connecting part 31 during rotation.

[0041] Specifically, such as Figures 1-3 As shown, the mortise and tenon connection node of the sloping roof eaves beam also includes a second bolt and a second nut. A second through hole 321 is provided on the second ear plate 32. The second bolt passes through the second through hole 321 and the second connecting part 31, and is threaded to the second nut, making the connection between the second connecting part 31 and the second ear plate 32 more stable. Through the above settings, the second connecting part 31 is firmly connected to the second connecting member 3. Construction personnel can adjust the tightness between the second bolt and the second nut, thereby adjusting the rotation angle of the second connecting part 31 relative to the second connecting member 3, thus adapting to the connection and installation of the second sloping beam 200 in different extension directions, making the operation more convenient and faster.

[0042] Specifically, such as Figures 1-3 As shown, the second connecting part 31 includes two second cover plates 311. One end of each second cover plate 311 is rotatably connected (e.g., via a pin, hinge, or other connection method) to the second connecting member 3, and the other end can be interlocked and fitted onto the second inclined beam 200. This not only simplifies the installation process but also improves the stability of the connection. When the two second cover plates 311 are interlocked and tightly fitted onto the second inclined beam 200, a stable support groove structure is formed, ensuring that the second inclined beam 200 is inserted into the support groove without loosening or displacement.

[0043] More specifically, one end of the second inclined beam 200 is clamped between two second cover plates 311. The second cover plates 311 have through holes, through which bolts pass and onto the second inclined beam 200, and are threaded onto nuts, thus achieving a stable connection between the second cover plates 311 and the second inclined beam 200. Furthermore, this facilitates the disassembly and assembly of these components by construction personnel, making construction more convenient.

[0044] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the second connector 3 is provided with multiple slots 33, and the support frame 1 is provided with multiple protrusions 11. The multiple slots 33 are spaced apart circumferentially along the second connector 3 and can be respectively engaged with the multiple protrusions 11, making the connection between the second connector 3 and the support frame 1 more stable and reliable, effectively resisting external forces and preventing the connection node from loosening or shifting during use. It can be understood that in other embodiments, the slots 33 are formed on the support frame 1, and the protrusions 11 are provided on the second connector 3, and the above function is achieved through the engagement between the slots 33 and the protrusions 11. The specific positions of the protrusions 11 and the slots 33 are not limited here.

[0045] More specifically, the slot 33 is opened at the end of the second connector 3 facing the support frame 1, and the protrusion 11 is set on the inner peripheral wall of the support cylinder 13. The second connector 3 is inserted into the support cylinder 13, so that multiple slots 33 and multiple protrusions 11 are interlocked with each other, thereby realizing a detachable connection between the second connector 3 and the support frame 1, and the connection stability is better.

[0046] More specifically, such as Figure 1 and Figure 3 As shown, in other embodiments, when the first connector 2 is sleeved on the support cylinder 13, one end of the second connector 3 can extend into and be threadedly connected to the support cylinder 13 of the support frame 1, so that the first connector 2 is sandwiched between the base plate 12 and the second connector 3, thereby realizing a detachable connection between the second connector 3 and the support frame 1. It is understood that the detachable connection method between the second connector 3 and the support frame 1 is not limited, as long as the above-mentioned functions can be achieved.

[0047] Specifically, such as Figures 1-3 As shown, when the first connector 2 is sleeved on the support cylinder 13, the second connector 3 can abut against the first connector 2, that is, the first connector 2 is sandwiched between the base plate 12 and the second connector 3, so that the first connector 2 is locked relative to the support frame 1, and the first connector 2 is firmly fixed on the support frame 1, reducing the safety hazards caused by loose connection. Moreover, it can prevent the first inclined beam 100 from being displaced or loosened due to external force during installation and use, thereby ensuring the overall stability and safety of the pitched roof structure.

[0048] It should be noted that in this embodiment, the first connecting member 2 and the second connecting member 3 include components such as steel pipes and steel sheets, and are prefabricated. In other embodiments, both the first connecting member 2 and the second connecting member 3 include steel columns, which not only facilitates the use of locally available materials but also provides higher strength; that is, the specific structure of the above components is not limited. Furthermore, during the installation of the above components, washers are provided at the connection points between the bolts and nuts to improve the connection stability of each component during installation and prevent loosening.

[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.
