Description

Technical Field

[0001] This utility model relates to the field of connection structure technology for wooden buildings, specifically a lightweight connection structure suitable for wooden buildings. Background Technology

[0002] Traditional wooden buildings often use mortise and tenon joints or metal connectors (such as bolts and steel plates) to connect components. While mortise and tenon joints offer advantages such as convenient construction and no need for additional materials, their earthquake resistance and lateral load resistance are relatively weak, making them prone to loosening due to vibration or wind, thus affecting structural stability. Although metal connectors can enhance the stiffness of joints, they have the following problems:

[0003] For example, the use of prefabricated panel modules in lightweight modular timber structures simplifies on-site assembly, but the connection nodes still rely on traditional mortise and tenon joints or metal parts, which still have the problem of insufficient stability. Some existing patents propose gear transmission or multi-directional clamp designs, which can achieve tool-free installation, but the mechanism is complex and the manufacturing cost is high, making it difficult to promote. Therefore, we provide a lightweight connection structure suitable for timber buildings to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight connection structure suitable for wooden buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lightweight connection structure suitable for wooden buildings includes a connector for connecting multiple wooden components. The connector has positioning grooves on all four sides and installation grooves at its four corners. A first installation hole penetrating the connector is formed in the bottom wall of each installation groove. A positioning block is fixed to the end of each wooden component and is movably engaged within the positioning groove. The wooden component and the connector are connected by a mortise and tenon joint. The positioning block and the connector are connected by a bolt locking assembly. An elastic stop assembly is provided within the positioning groove to limit the top of the positioning block after it is movably engaged within the groove.

[0007] As described above, a lightweight connection structure suitable for wooden buildings includes tenons fixed around the connector and mortises on both sides of the wooden component, wherein the tenons and mortises are movably engaged.

[0008] As described above, a lightweight connection structure suitable for wooden buildings includes a bolt locking assembly comprising a second mounting hole on the inner sidewall of the mounting groove and a third mounting hole on the positioning block. The positioning block and the connector are locked together by locking bolts inserted into the second and third mounting holes.

[0009] As described above, a lightweight connection structure suitable for wooden buildings includes an elastic stop assembly comprising a slot formed in the inner wall of a positioning groove, a wedge block disposed within the slot, the wedge block being slidably engaged within the slot via a snap-fit ​​assembly, and a spring being fixedly connected between the wedge block and the inner wall of the slot.

[0010] A lightweight connection structure suitable for wooden buildings as described above: the snap-fit ​​assembly includes a sliding plate fixed to both ends of a wedge block and a sliding groove formed on the inner walls of both sides of the slot, wherein the sliding plate is movably snapped into the inside of the sliding groove.

[0011] As described above, a lightweight connection structure suitable for wooden buildings is provided: the thickness of the positioning block is adapted to the depth of the positioning groove so that when the positioning block is embedded and engaged inside the positioning groove and its bottom surface contacts the bottom wall inside the positioning groove, the wedge block can abut against the top of the positioning block.

[0012] As described above, a lightweight connection structure suitable for wooden buildings is provided: the upper edge of the wedge-shaped block is treated with a rounded transition.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When connecting wooden components and connectors, the positioning block, embedded in the positioning groove, enables rapid positioning and installation. After the positioning block is engaged in the groove, the tenon is engaged in the mortise. The mortise and tenon structure formed between the tenon and mortise secures the connection between the wooden component and connector, preventing horizontal displacement or detachment. The positioning block and connector are connected by a bolt locking assembly, which further secures them. Furthermore, this invention incorporates a positioning groove... An elastic stop component is provided to limit the top of the positioning block after it is movably engaged inside the positioning groove. Even if the bolt locking component loosens after the connection between the wooden component and the connector, it can ensure that the wooden component and the connector will not shift or fall off in the vertical direction, thus ensuring the stability of the wooden component and the connector after connection. Therefore, this utility model improves the pull-out resistance and anti-fall-off performance of the wooden component by stopping and limiting the top of the positioning block through the barbed protrusion structure of the elastic stop component. Moreover, the elastic stop component has a simple structure and is lightweight, meeting the requirements of efficient assembly and multi-directional stability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-5 As an embodiment of this utility model, a lightweight connection structure suitable for wooden buildings includes a connector 1 for connecting multiple wooden components 7. The connector 1 has positioning grooves 2 on its four sides and installation grooves 3 at its four corners. The bottom wall of the installation groove 3 has a first installation hole 4 that penetrates the connector 1. The end of the wooden component 7 is fixed with a positioning block 9 that is movably engaged in the positioning groove 2. The wooden component 7 and the connector 1 are engaged by a mortise and tenon structure. The positioning block 9 and the connector 1 are connected by a bolt locking assembly. The positioning groove 2 is provided with an elastic stop assembly for limiting the top of the positioning block 9 after it is movably engaged in the positioning groove 2.

[0023] In this embodiment, the first mounting hole 4 is used to connect the connector 1 to the main building with bolts. When connecting the wooden component 7 and the connector 1, the positioning block 9 is embedded and snapped into the positioning groove 2 to achieve quick positioning and installation between the wooden component 7 and the connector 1. After the positioning block 9 is snapped into the positioning groove 2, the tenon 6 is just snapped into the mortise 8. The tenon and mortise 8 form a tenon and mortise structure to fix the wooden component 7 and the connector 1, ensuring that the wooden component 7 and the connector 1 will not shift or fall off in the horizontal direction. The positioning block 9 and the connector 1 are connected by a bolt locking assembly, which further fixes the positioning block 9 and the connector 1. In addition, this utility model provides an elastic stop assembly in the positioning groove 2 to limit the top of the positioning block 9 after it is movably snapped into the positioning groove 2. Even if the bolt locking assembly loosens after the wooden component 7 and the connector 1 are connected, it can still ensure that the wooden component 7 and the connector 1 will not shift or fall off in the vertical direction, ensuring the stability of the wooden component 7 and the connector 1 after connection.

[0024] As a further embodiment of this utility model, the mortise and tenon structure includes tenons 6 fixed around the four sides of the connector 1 and mortises 8 opened on both sides of the wooden component 7, with the tenons 6 and mortises 8 engaging and locking with each other.

[0025] In this embodiment, a rigid connection is formed by the precise interlocking of the tenon 6 and the mortise 8, which achieves high-strength fixation between the wooden component 7 and the connector 1 without the need for metal nails. This design makes full use of the fiber strength and friction of the wood, making the structure difficult to loosen.

[0026] As a further embodiment of this utility model, the bolt locking assembly includes a second mounting hole 5 opened in the inner side wall of the mounting groove 3 and a third mounting hole 10 opened in the positioning block 9. The positioning block 9 and the connector 1 are locked together by locking bolts inserted into the second mounting hole 5 and the third mounting hole 10.

[0027] In this embodiment, a rigid connection between the wooden component 7 and the connector 1 is achieved by fixing the positioning block 9 and the connector 1 with a bolt locking assembly, ensuring that the wooden component 7 and the connector 1 will not loosen in the horizontal and vertical directions.

[0028] As a further embodiment of this utility model, the elastic stop assembly includes a slot 11 formed in the inner wall of the positioning groove 2, a wedge block 13 is provided in the slot 11, the wedge block 13 is slidably engaged in the slot 11 by a snap-fit ​​assembly, and a spring 14 is fixedly connected between the wedge block 13 and the inner wall of the slot 11.

[0029] In this embodiment, when the positioning block 9 at the end of the wooden component 7 is inserted and engaged in the positioning groove 2 from top to bottom, it will squeeze the wedge block 13. Since the wedge block 13 is slidably engaged in the groove 11 through the engaging component, the wedge block 13 can move horizontally in the groove 11. Thus, the wedge block 13 will overcome the elastic force of the spring 14 and squeeze the spring 14 to move into the groove 11. When the positioning block 9 is inserted and engaged in the positioning groove 2 and the bottom surface contacts the bottom wall of the positioning groove 2, the positioning block 9 reaches the bottom of the wedge block 13. The spring 14 elastically resets and drives the wedge block 13 to move outward in the groove 11 so that the wedge block 13 can press against the top of the positioning block 9 to limit the top of the positioning block 9.

[0030] As a further embodiment of this utility model, the snap-fit ​​assembly includes a slide plate 15 fixed to both ends of the wedge block 13 and a slide groove 12 formed on the inner walls of both sides of the slot 11, with the slide plate 15 movably snapped into the inside of the slide groove 12.

[0031] In this embodiment, the sliding plate 15 is movably engaged inside the sliding groove 12 to limit the movement of the wedge block 13 inside the slot 11, thereby ensuring the stability of the wedge block 13 when moving horizontally.

[0032] As a further embodiment of this utility model, the thickness of the positioning block 9 is adapted to the depth of the positioning groove 2 so that when the positioning block 9 is embedded and engaged inside the positioning groove 2 and its bottom surface contacts the bottom wall inside the positioning groove 2, the wedge block 13 can abut against the top of the positioning block 9.

[0033] In this embodiment, when the positioning block 9 is embedded and snapped into the positioning groove 2 and its bottom surface contacts the bottom wall of the positioning groove 2, the positioning block 9 reaches the bottom of the wedge block 13. The spring 14 elastically resets and drives the wedge block 13 to move outward in the slot 11 so that the wedge block 13 can press against the top of the positioning block 9 to limit the top of the positioning block 9.

[0034] As a further embodiment of this utility model, the upper edge 16 of the wedge block 13 is treated with a rounded transition.

[0035] In this embodiment, the frictional resistance of the positioning block 9 when pressing against the wedge block 13 is reduced, making the downward movement of the positioning block 9 smoother.

[0036] In use, when connecting multiple wooden components 7 and connectors 1, firstly, the positioning block 9 at the end of the wooden component 7 is embedded and snapped into the positioning groove 2 to achieve quick positioning and installation between the wooden component 7 and the connector 1. After the positioning block 9 is snapped into the positioning groove 2, the tenon 6 is just snapped into the mortise 8. The mortise and tenon structure formed between the tenon 6 and the mortise 8 achieves the connection and fixation between the wooden component 7 and the connector 1, ensuring that the wooden component 7 and the connector 1 will not shift or fall off in the horizontal direction. The locking bolt is inserted into the second mounting hole 5 and the third mounting hole 10 to connect the positioning block 9 and the connector 1 through the bolt locking assembly. The bolt assembly further fixes the positioning block 9 and the connector 1. The positioning block 9 at the end of the wooden component 7 is embedded and snapped into the positioning groove 2 from top to bottom. When the wedge block 13 is pressed, it is slidably engaged in the slot 11 through the snap-fit ​​assembly, so the wedge block 13 can move horizontally in the slot 11. Thus, the wedge block 13 will overcome the elastic force of the spring 14 and push the spring 14 into the slot 11. When the positioning block 9 is embedded in the positioning groove 2 and its bottom surface contacts the bottom wall of the positioning groove 2, the positioning block 9 reaches the bottom of the wedge block 13. The spring 14 elastically resets and drives the wedge block 13 to move outward in the slot 11, so that the wedge block 13 can press against the top of the positioning block 9 to limit the top of the positioning block 9. After the connection between the wooden component 7 and the connector 1, even if the bolt locking assembly is loose, it can ensure that the wooden component 7 and the connector 1 will not be displaced or fall off in the vertical direction, thus ensuring the stability of the wooden component 7 and the connector 1 after connection.

[0037] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
