Description

Technical Field

[0001] This application relates to the field of structural building technology, and in particular to a ridge beam connection structure for wooden roofs. Background Technology

[0002] In traditional timber-framed buildings, the roof ridge is a crucial load-bearing node, typically constructed from components such as the ridge purlin and diagonal rafters. Traditional connection methods rely heavily on mortise and tenon joints or simple metal connectors, which have the following problems:

[0003] It is difficult to flexibly adjust to accommodate different roof slopes or angle changes between diagonal rafters, requiring custom components for each angle, which increases manufacturing costs and complexity.

[0004] When subjected to external forces such as wind and earthquakes, traditional nodes are prone to loosening or deformation, leading to a decrease in structural stability.

[0005] Therefore, there is an urgent need in this field for a wooden roof ridge beam connection structure that is infinitely adjustable, highly adaptable, easy to install, and can significantly improve structural stability and seismic performance. Summary of the Invention

[0006] The purpose of this application is to provide a wooden roof ridge beam connection structure to solve the above problems, which can automatically adapt to different installation angles between the first and second diagonal rafters through multiple hinges and universal adjustment, and form a stable triangular support system.

[0007] This application achieves the above objectives through the following technical solutions:

[0008] A ridge beam connection structure for a wooden roof includes a ridge purlin, a first diagonal rafter, and a second diagonal rafter. The first diagonal rafter and the second diagonal rafter overlap the ridge purlin, and there is an angle between the first diagonal rafter and the second diagonal rafter. Its characteristic is that:

[0009] It also includes two first connectors, a crossbeam, and multiple second connectors;

[0010] The two first connectors are respectively installed on the first diagonal rafter and the second diagonal rafter;

[0011] The two ends of the crossbeam are hinged to the bottom of the two first connectors via hinge assemblies, so that the first connectors can be adjusted to accommodate the installation angles of the first and second diagonal rafters.

[0012] Each of the first connectors is connected to the second connector on both sides by a connecting rod, and the second connector is fixedly connected to the ridge purlin;

[0013] Both ends of the connecting rod are provided with universal structures, which can be used to adjust the installation position and angle of the second connecting member to accommodate different installation angles between the first and second diagonal rafters.

[0014] In some embodiments, the first connector is U-shaped and is respectively mounted on the first diagonal rafter and the second diagonal rafter by connector fasteners.

[0015] In some embodiments, the hinge assembly includes a support and a pin. The support is fixedly connected to the first connector, and the pin is fixedly connected to the support. Both ends of the crossbeam are integrally formed with blades, and the blades are rotatably connected to the pin to realize the hinge connection between the crossbeam and the first connector.

[0016] In some embodiments, the universal structure includes a sphere, a mounting plate, a first column, and a second column;

[0017] The sphere is fixedly connected to the end of the connecting rod;

[0018] The mounting plate is fixedly connected to the first connector or the second connector;

[0019] The first column is fixedly connected to the mounting plate, and the second column is detachably connected to the first column. The first column and the second column have spherical cavities adapted to the sphere. When the first column and the second column are assembled, they form a complete spherical cavity. The sphere is movably disposed in the spherical cavity to achieve universal adjustment.

[0020] In some embodiments, a prismatic ring is further included, which is sleeved at the joint between the first column and the second column. The outer wall of the prismatic ring is a polygonal prism. At least two prismatic ring fasteners are provided on each side of the prismatic ring. The prismatic ring fasteners are respectively connected to the first column and the second column to fasten the prismatic ring to the first column and the second column, thereby fixing the sphere inside the spherical cavity.

[0021] In some embodiments, the outer wall of the prismatic ring is a pentagonal prism, a quadrilateral prism, or a hexagonal prism.

[0022] In some embodiments, the second connector is plate-shaped and is fixedly connected to the ridge purlin by connector fasteners.

[0023] In some embodiments, the crossbeam is hinged to the two first connectors via the hinge assembly to form a support structure, thereby stabilizing the angles of the first and second diagonal rafters; simultaneously, the connecting rod is connected to the first and second connectors via the universal joint to form a triangular structure, thereby increasing the stability and seismic resistance between the ridge purlin, the first diagonal rafter, and the second diagonal rafter.

[0024] Compared with existing technologies, this application achieves stepless adjustment of the connection structure in multiple directions through the hinged connection between the crossbeam and the bottom of the first connecting member, and the universal structure set at both ends of the connecting rod. It can perfectly adapt to various roof slopes and rafter angles, and has strong versatility.

[0025] The crossbeam provides the main support at the bottom, forming a triangular structure with the first and second diagonal rafters, while the first connector, connecting rod, and second connector form a stable triangular support structure. This multi-member, multi-angle connection method effectively distributes and transfers loads, enhancing the overall stiffness and deformation resistance of the ridge joint.

[0026] Because each connection point is adjustable, the requirements for the precision of the wooden components in processing and the precision of on-site installation are reduced. During installation, the main components can be initially fixed first, and then the universal joints and hinge points can be adjusted to make the components fit tightly together. Finally, the fasteners can be tightened. Attached Figure Description

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] like Figure 1-4 As shown, a ridge beam connection structure for a wooden house is mainly used to connect the main ridge purlin 1, the first diagonal rafter 2, and the second diagonal rafter 3 of the wooden house roof. The ends of the first diagonal rafter 2 and the second diagonal rafter 3 are usually overlapped on the main ridge purlin 1 at a certain angle to form the framework of the roof.

[0037] like Figure 1 As shown, the connection structure mainly includes two first connecting members 4, a crossbeam 6, and four second connecting members 7. In some preferred embodiments, the two first connecting members 4 are respectively fixed to the bottom of the first diagonal rafter 2 and the second diagonal rafter 3 by connecting fasteners 16 (e.g., high-strength bolts or self-tapping screws). The crossbeam 6 is horizontally arranged, and its two ends are connected to the bottom of the two first connecting members 4 by hinge assemblies, which will be detailed below, thereby providing a downward support force for the two diagonal rafters and allowing them to swing freely within a certain angle range.

[0038] Furthermore, a connecting rod 8 is connected to each of the two sides (i.e., the two outer walls of the U-shaped opening) of each first connector 4. The other end of each connecting rod 8 is connected to a second connector 7. Therefore, a total of four connecting rods 8 and four second connectors 7 are used. These second connectors 7 are fixedly installed on the sides of the ridge purlin 1 by connector fasteners 16. In this way, two symmetrical triangular stable structures are formed between the ridge purlin 1 and each diagonal rafter, consisting of the first connectors 4, the connecting rods 8, and the second connectors 7.

[0039] like Figure 2 As shown, the first connector 4 is designed in a U-shape, which can clamp the bottom and sides of the diagonal rafter like a clamp, and is secured by connector fasteners 16 that penetrate its sidewalls. This structure provides a stable connection.

[0040] Furthermore, a support 14 is fixedly connected to the bottom outer side of the first connecting member 4. A pin 15 is fixedly installed on the support 14, and the axis of the pin 15 is approximately horizontal. The two ends of the crossbeam 6 are not directly connected to the support 14, but are integrally formed with outwardly extending blades 18. In some specific embodiments, the blades 18 can be one or more parallel lugs with through holes. The through holes on the blades 18 are fitted onto the pins 15, thereby achieving a hinge connection between the crossbeam 6 and the first connecting member 4. This means that when the included angle between the first diagonal rafter 2 and the second diagonal rafter 3 changes, the two first connecting members 4 can rotate slightly around their respective pins 15, and the crossbeam 6 will adjust accordingly without generating constraint stress.

[0041] The universal joints at both ends of link 8 provide the entire connection structure with a high degree of adjustability. Please refer to the following for details. Figure 3 and Figure 4 .

[0042] The universal structure mainly includes a ball 9, a mounting plate 10, a first column 11, and a second column 12. The ball 9 is fixedly connected to the end of the connecting rod 8, for example, by welding or by machining one end of the connecting rod 8 into an integral part of the ball 9.

[0043] Furthermore, the mounting plate 10 is used to fix the entire universal structure to the target component. Specifically, for the universal structure connected to the first connector 4, the mounting plate 10 is fixed to the side of the first connector 4 by fasteners; for the universal structure connected to the second connector 7, the mounting plate 10 is fixed to the second connector 7.

[0044] One end of the first column 11 is fixedly connected to the mounting plate 10, and the other end is provided with a hemispherical cavity. Correspondingly, the second column 12 is also provided with a matching hemispherical cavity. When the first column 11 and the second column 12 are aligned, their cavities together form a complete spherical cavity for accommodating the sphere 9.

[0045] In some preferred embodiments, in order to securely lock the first column 11 and the second column 12 together, and simultaneously lock the sphere 9, this application also provides a prismatic ring 13. The inner wall shape of the prismatic ring 13 is adapted to the outer wall shape formed after the first column 11 and the second column 12 are engaged. The outer wall of the prismatic ring 13 is designed as a polygonal prism, such as a quadrilateral, pentagonal, or hexagonal prism.

[0046] Furthermore, at least two (preferably an even number) prismatic ring fasteners 17 are provided on each side of the prismatic ring 13. These prismatic ring fasteners 17 can be screws or bolts. They are screwed in from the outside of the prismatic ring 13, and their ends are respectively connected to the first post 11 and the second post 12. By uniformly tightening all these prismatic ring fasteners 17, the prismatic ring 13 generates a strong clamping force, tightly holding the first post 11 and the second post 12 together, preventing them from separating, thereby preventing the ball 9 from detaching. When adjustment is required, the connecting rod 8 changes its angle, causing the ball 9 to rotate in any direction within the spherical cavity, so that the first connecting member 4 and the corresponding second connecting member 7 always maintain a stable structure.

[0047] When installing the connection structure described in this application, the following steps can be followed:

[0048] Initially clamp the two first connectors 4 to the predetermined positions of the first diagonal rafters 2 and 3. Connect the blades 18 at both ends of the crossbeam 6 to the pins 15 at the bottom of the first connectors 4 to complete the construction of the bottom support frame. Initially fix the four second connectors 7 to the predetermined positions of the ridge purlin 1. Connect the four connecting rods 8. The ball 9 can rotate in any direction within the spherical cavity, thereby adjusting the angle of the four connecting rods 8 to adapt to the installation position of the second connectors 7. Slowly adjust the entire roof truss structure so that the ridge purlin 1, the first diagonal rafters 2, and the second diagonal rafters 3 move to the designed positions and are initially fixed. During this process, all hinge points and universal joints will automatically adapt and find the most suitable positions. At this time, check whether all connectors are in close contact with the surface of the wooden components. After confirming that the positions are correct, tighten the fasteners 16 on the first connectors 4 and the second connectors 7.

[0049] When subjected to external forces (such as wind or earthquake), the crossbeam 6 can form a triangular structure with the first diagonal rafter 2 and the second diagonal rafter 3, providing the main bending resistance and support. The multiple triangular structures formed by the first connector 4, the connecting rod 8, and the second connector 7 can effectively distribute and transfer the load to the ridge purlin 1 and the supporting structure below, avoiding stress concentration and significantly improving the energy dissipation capacity of the joint and the overall stability.

Those skilled in the art should understand that this application is not limited to the above embodiments.
