Description

Technical Field

[0001] This application relates to the technical field of timber frame connection structures, and in particular to node connection structures for glued laminated timber mesh shell structures. Background Technology

[0002] Glulam (glulam) structures offer advantages such as lightweight, environmental friendliness, and ease of construction and installation. They also allow for prefabricated construction, making them highly suitable for buildings with special functions or those requiring a timber-frame aesthetic. Glulam materials are a renewable resource, aligning with the current trend in architectural design towards green, environmentally friendly, and prefabricated installation methods.

[0003] However, most current large-span space grid shell structure engineering projects are steel or aluminum alloy structures. Due to the uneven material composition of glued laminated timber (GLLT) structures, its cross-grain stress is relatively weak. Achieving rigid connections between GLLT beams is difficult, making many structural systems unsuitable. Therefore, GLLT structures are rarely used in engineering projects.

[0004] Regarding the aforementioned technologies, it has been found that in the existing wood mesh shell installation process, the wooden frames are often connected by mortise and tenon joints or directly fixed by bolts. The mortise and tenon joints require a relatively complex installation, while the direct fixing by bolts can easily lead to uneven stress on the wooden frame, resulting in deformation or even damage. Utility Model Content

[0005] To achieve stable connections and strength between timber frames, this application provides a node connection structure for glued laminated timber shell frames.

[0006] The node connection structure of the glued laminated timber reticulated shell frame provided in this application adopts the following technical solution:

[0007] The node connection structure of the glued laminated timber frame includes a first timber frame and a second timber frame. The first timber frame is connected to the second timber frame through a node frame, and both the first and second timber frames are fixedly connected to the node frame. The node frame includes a middle seat, an upper clamping plate, and a lower clamping plate. There are two sets of both the upper and lower clamping plates. The middle seat, upper clamping plate, and lower clamping plate are integrally formed. The first timber frame is installed on the upper end face of the middle seat, and the upper clamping plate is fixedly connected to the first timber frame through a connector. The second timber frame is installed on the lower end face of the middle seat, and the lower clamping plate is fixedly connected to the second timber frame through a connector.

[0008] By adopting the above technical solution, the arrangement of the first and second wooden frames facilitates the demonstration of how the wooden frames are connected and fixed through node frames. When the first and second wooden frames need to be connected to each other, the node frame can be installed between the two sets of wooden frames to fix the first and second wooden frames to each other. At the same time, by designing the node frame as a structure with a middle seat, upper clamping plate and lower clamping plate in cooperation, it is easy to use. The upper clamping plate and lower clamping plate can be connected to each other through the middle seat. In this way, when connected to the wooden frame, the two sets of upper clamping plates can be used to clamp the first wooden frame, and the two sets of lower clamping plates can be used to clamp the second wooden frame. After the first and second wooden frames are installed on the clamping plates, they can be locked by connectors to ensure that the first and second wooden frames are fixed on the node frame, thus achieving the purpose of fixing the first and second wooden frames to each other.

[0009] Optionally, the lower end face of the first wooden frame is provided with a first slot that mates with the middle seat, and the first wooden frame is also provided with a first through hole that communicates with the first slot.

[0010] By adopting the above technical solution, by opening a first slot on the lower end face of the first wooden frame, it is easy to use to install the middle seat on the node frame through the first slot. During installation, it can be quickly positioned and installed after being engaged with the middle seat through the first slot. At the same time, the setting of the first through hole facilitates pre-fixation.

[0011] Optionally, the upper end face of the second wooden frame is provided with a second slot that cooperates with the middle seat, and the second wooden frame is also provided with a second through hole that communicates with the second slot.

[0012] By adopting the above technical solution, by opening a second slot on the upper end face of the second wooden frame, it is easy to use to install the middle seat on the node frame through the second slot. During installation, after the second slot is engaged with the middle seat, it can be quickly positioned and installed. At the same time, the second through hole is set to cooperate with the first through hole for pre-fixing.

[0013] Optionally, the center of the middle seat is provided with a central groove corresponding to the first slot and the second slot, and positioning wooden pins are inserted and fixed in the first slot, the second slot and the central groove.

[0014] By adopting the above technical solution, a central groove corresponding to the first and second slots is opened in the center of the middle seat. This ensures that the first slot is connected to the second slot through the central groove, and the positioning wooden pin is better inserted during the later pre-positioning. This ensures that the first and second wooden frames are stably installed on the node frame, and facilitates better installation of connecting parts in the later stage.

[0015] Optionally, both the upper and lower clamping plates are symmetrically provided with a number of connection holes for installing connectors.

[0016] By adopting the above technical solution, and by symmetrically opening connection holes on the upper and lower clamping plates, it is ensured that the connectors can be directly inserted through the connection holes during installation, making it easier to connect and fix them.

[0017] Optionally, the connector includes a nut, a screw, and a locking nut. The nut is fixedly installed at one end of the screw, and the locking nut is installed at the other end of the screw, with the locking nut threadedly connected to the screw.

[0018] By adopting the above technical solution, the connector is designed with a nut, screw and locking nut in a matching structure. When easy to use, the screw can be inserted into the connection hole for connection. At the same time, by setting the nut and locking nut at both ends of the screw, it can be quickly locked when in use.

[0019] Optionally, a cover assembly consisting of a protective nut and a locking nut is installed between the upper and lower clamping plates, and both the upper and lower clamping plates are bonded and fixed to the cover assembly.

[0020] By adopting the above technical solution, a cover assembly is installed between the upper and lower clamping plates. During use, the cover assembly can protect the installed protective nuts and locking nuts, ensuring their safety during use and preventing corrosion.

[0021] Optionally, the cover assembly includes a first cover, a second cover, and a connecting corner plate, wherein the connecting corner plate is installed between the first cover and the second cover, and the first cover, the second cover, and the connecting corner plate are integrally formed.

[0022] By adopting the above technical solution, the cover assembly is designed as a structure in which a first cover, a second cover, and a connecting angle plate cooperate. When in use, the first cover and the second cover can protect the nuts and locking nuts on both sides respectively. At the same time, the connecting angle plate ensures that the first cover and the second cover can be fixed perpendicularly to each other, thus facilitating more stable protection.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By setting a node frame between the first and second wooden frames, the wooden frames can be connected through the node frame when easy to use. Furthermore, by designing the node frame as a structure in which the middle seat, upper clamping plate, and lower clamping plate cooperate, the wooden frame can cooperate with the middle seat through the slots on the wooden frame when easy to use. After the wooden frame is engaged with the middle seat through the slots, it can be locked by positioning wooden pins, which facilitates better installation of connectors. Moreover, after the wooden frame is installed on the node frame, it can be clamped by two sets of clamping plates, which can effectively increase the strength of the wooden frame connection position and has the advantages of easy and flexible installation and high connection strength.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses the node connection structure of a glued laminated timber reticulated shell frame. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, the node connection structure of the glued laminated timber frame includes a first timber frame 1 and a second timber frame 2. The first timber frame 1 is connected to the second timber frame 2 through a node frame 3, and both the first timber frame 1 and the second timber frame 2 are fixedly connected to the node frame 3. The node frame 3 includes a middle seat 31, an upper clamping plate 32, and a lower clamping plate 33. There are two sets of upper clamping plates 32 and lower clamping plates 33. The middle seat 31, upper clamping plate 32, and lower clamping plate 33 are integrally formed. The first timber frame 1 is installed on the upper end face of the middle seat 31, and the upper clamping plate 32 is fixedly connected to the first timber frame 1 through a connector 4. The second timber frame 2 is installed on the lower end face of the middle seat 31, and the lower clamping plate 33 is fixedly connected to the second timber frame 2 through a connector 4. The setup of the first wooden frame 1 and the second wooden frame 2 facilitates the demonstration of how the wooden frames are connected and fixed together via the node frame 3. When the first wooden frame 1 and the second wooden frame 2 need to be connected to each other, the node frame 3 can be installed between the two sets of wooden frames to fix the first wooden frame 1 and the second wooden frame 2 together. At the same time, by designing the node frame 3 as a structure in which the middle seat 31, the upper clamping plate 32 and the lower clamping plate 33 cooperate, it is easy to use. The middle seat 31 can be used to connect the upper clamping plate 32 and the lower clamping plate 33 together. In this way, when connected to the wooden frame, the two sets of upper clamping plates 32 can be used to clamp the first wooden frame 1, and the two sets of lower clamping plates 33 can be used to clamp the second wooden frame 2. After the first wooden frame 1 and the second wooden frame 2 are installed on the clamping plates, they can be locked by the connector 4 to ensure that the first wooden frame 1 and the second wooden frame 2 are fixed on the node frame 3, thus achieving the purpose of fixing the first wooden frame 1 and the second wooden frame 2 together. The lower end face of the first wooden frame 1 is provided with a first slot 11 that mates with the middle seat 31, and the first wooden frame 1 is also provided with a first through hole 12 that communicates with the first slot 11. By providing the first slot 11 on the lower end face of the first wooden frame 1, it is easy to use to mate and install the middle seat 31 on the node frame 3. During installation, it can be quickly positioned and installed after the first slot 11 is engaged with the middle seat 31. At the same time, the first through hole 12 facilitates pre-fixation.

[0034] Reference Figure 2 As shown, the upper end face of the second wooden frame 2 is provided with a second slot 21 that mates with the middle seat 31, and the second wooden frame 2 is also provided with a second through hole 22 that communicates with the second slot 21. By providing the second slot 21 on the upper end face of the second wooden frame 2, it is easy to use to mate and install the middle seat 31 on the node frame 3. During installation, after the second slot 21 is engaged with the middle seat 31, it can be quickly positioned and installed. At the same time, the second through hole 22 is provided to cooperate with the first through hole 12 for pre-fixation.

[0035] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the center of the middle base 31 has a central groove 311 corresponding to the first slot 11 and the second slot 21, and positioning wooden pins 312 are inserted and fixed in the first slot 11, the second slot 21 and the central groove 311. By opening a central groove 311 corresponding to the first slot 11 and the second slot 21 in the center of the middle base 31, it is ensured that the first slot 11 is connected to the second slot 21 through the central groove 311. This facilitates the insertion of the positioning wooden pins 312 during later positioning, ensuring that the first wooden frame 1 and the second wooden frame 2 are stably installed on the node frame 3, and facilitating the later installation of the connectors 4. Several connecting holes 321 for installing the connectors 4 are symmetrically opened on both the upper clamping plate 32 and the lower clamping plate 33. By symmetrically opening connecting holes 321 on the upper clamping plate 32 and the lower clamping plate 33, it is ensured that the connector 4 can be directly inserted through the connecting holes 321 during installation, which facilitates better connection and fixation through the connector 4.

[0036] Reference Figure 3 As shown, the connector 4 includes a nut 41, a screw 42, and a locking nut 43. The nut 41 is fixedly installed at one end of the screw 42, and the locking nut 43 is installed at the other end of the screw 42, with the locking nut 43 threadedly connected to the screw 42. By designing the connector 4 with a structure in which the nut 41, screw 42, and locking nut 43 mate, it is easy to use by inserting the screw 42 into the connecting hole 321 for connection. At the same time, by setting the nut 41 and locking nut 43 at both ends of the screw 42, it ensures that it can be quickly locked during use.

[0037] Reference Figure 2 and Figure 7 As shown, a cover assembly 5 consisting of a protective nut 41 and a locking nut 43 is installed between the upper clamping plate 32 and the lower clamping plate 33. Both the upper clamping plate 32 and the lower clamping plate 33 are glued and fixed to the cover assembly 5. By installing the cover assembly 5 between the upper clamping plate 32 and the lower clamping plate 33, the installed protective nut 41 and locking nut 43 can be protected during use, ensuring the safety of the nut 41 and locking nut 43 during use and preventing corrosion. The cover assembly 5 includes a first snap shell 51, a second snap shell 52, and a connecting angle plate 53. The connecting angle plate 53 is installed between the first snap shell 51 and the second snap shell 52, and the first snap shell 51, the second snap shell 52, and the connecting angle plate 53 are integrally formed. By designing the cover assembly 5 into a structure in which the first cover 51, the second cover 52, and the connecting angle plate 53 cooperate, it is easy to use. The first cover 51 and the second cover 52 can protect the nuts 41 and the locking nuts 43 on both sides respectively. At the same time, the connecting angle plate 53 ensures that the first cover 51 and the second cover 52 can be fixed perpendicularly to each other, thus facilitating more stable protection.

[0038] The implementation principle of the node connection structure of the glued laminated timber frame in this application embodiment is as follows: During actual connection, the first timber frame 1 is engaged with the upper end of the middle seat 31 through the first slot 11, and the second timber frame 2 is engaged with the lower end of the middle seat 31 through the second slot 21. Then, the positioning wooden pin 312 is inserted from the lower end of the second through hole 22 of the second timber frame 2, and after passing through the central groove 311 of the middle seat 31, it can be inserted and fixed in the first through hole 12 of the first timber frame 1. In this way, the first timber frame 1 and the second timber frame 2 can be pre-fixed on the node frame 3 by the positioning wooden pin 312, which makes it easy for the operator to easily insert and install the connector 4. When installing the connector 4, the locking nut 43 on the screw 42 can be removed, and then the screw 42 can be passed through the connecting hole 321 on the clamp to fix the timber frame and the clamp to each other. The operation is very convenient.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
