Description

Technical Field

[0001] This invention relates to the field of timber beam connections. More specifically, this invention relates to a timber beam connection node that can rotate and move in both directions. Background Technology

[0002] As one of the three major prefabricated building forms, timber structure boasts advantages such as lightweight, environmental friendliness, and a high degree of prefabrication, making it highly suitable for buildings with special functions or those requiring the aesthetic appeal of timber structures. Timber is a renewable resource, and its warm, natural characteristics align with the current trend in architectural structural design towards green environmental protection and prefabricated installation. However, due to the uneven texture and low hardness of timber, most timber components are connected using steel plates, bolts, and self-tapping screws. The joint areas of timber components require pre-reserved grooves and bolt holes, and precise alignment with the steel plates. In actual projects, errors in the fabrication and installation of timber components make on-site correction difficult and time-consuming, often necessitating factory remanufacturing and replacement, which is extremely inconvenient. For example, CN 111379317 B provides a joint connection structure for a glued laminated timber (Glulam) mesh shell frame, composed of glued laminated timber components, cross-shaped steel inserts, and bolts. By changing the groove angle and the design of the steel connectors, the angle between the overlapping glued laminated timber components can be altered, effectively reducing exposed metal connectors and improving joint durability. This node is a typical insert-plate bolt connection. The grooves in the wooden components and the cross-shaped steel inserts, as well as the pre-drilled bolt holes in the wooden components and the bolt holes on the steel inserts, must be highly aligned. This places high demands on the tolerance for horizontal relative position or angular errors during the fabrication and installation of the wooden components. Furthermore, this node type requires that the wooden components not overlap on the same plane, preventing the convergence of force lines and direct force transmission. CN113323149B provides a glued laminated timber prestressed sleeve bolt node and its construction method. The node includes a wooden column, a wooden beam, an inner round outer square sleeve, a T-shaped steel clamp, and bolts. The flanges of the T-shaped steel clamp are fixed to the sidewalls of the wooden column by bolts, and the wooden beam is connected to the web of the T-shaped steel clamp by bolts and the inner round outer square sleeve. This node is also a typical insert-plate bolt connection. The grooves in the wooden beam and the web of the T-shaped steel clamp, as well as the pre-drilled bolt holes in the wooden beam and the bolt holes on the web of the T-shaped steel clamp, must be highly aligned. This also places high demands on the tolerance for horizontal relative position or angular errors during the fabrication and installation of the wooden components. Summary of the Invention

[0003] One object of the present invention is to provide a wooden beam connection node that can rotate and move in both directions, so as to at least solve the above-mentioned problems.

[0004] To achieve the objectives and other advantages of this invention, a bidirectional rotatable and bidirectional movable wooden beam connection node is provided, comprising: a first wooden beam, a second wooden beam, and a T-shaped steel plate connector, wherein the first wooden beam and the second wooden beam are connected by the T-shaped steel plate connector; wherein...

[0005] The T-shaped steel plate connector includes a wedge-shaped steel plate, a transition steel plate, and a connecting steel plate. The wedge-shaped steel plate is connected to the first wooden beam. The transition steel plate intersects with and is rotatably connected to the wedge-shaped steel plate. The connecting steel plate is parallel to the transition steel plate, and one end of the connecting steel plate is rotatably connected to the transition steel plate, while the other end is connected to the second wooden beam.

[0006] Furthermore, the wedge-shaped steel plate is provided with a plurality of elliptical elongated holes, each elliptical elongated hole being arranged along the length direction of the first wooden beam, and the first wooden beam being provided with a first through hole that mates with the elliptical elongated holes, and the wedge-shaped steel plate being connected to the first wooden beam via a first bolt passing through the elliptical elongated holes and the first through hole.

[0007] Furthermore, the wedge-shaped steel plate has a protruding central portion and a circular slot, which is arranged along the width direction of the wedge-shaped steel plate. Both ends of the circular slot are provided with internal threads, and the side of the circular slot away from the wedge-shaped steel plate has an elongated opening that penetrates the sidewall of the circular slot. One end of the transition steel plate is fixed with a cylindrical joint, and the transition steel plate and the wedge-shaped steel plate are rotatably connected via the cylindrical joint inserted into the circular slot and fixed by a second bolt that is screwed to the internal thread.

[0008] Furthermore, the transition steel plate is provided with a central hole and a plurality of arc-shaped elongated holes, the plurality of arc-shaped elongated holes being arranged in an array at equal intervals around the central hole. One end of the connecting steel plate is provided with a first bolt hole and a plurality of second bolt holes. The first bolt hole mates with the central hole and is connected by a third bolt. The plurality of second bolt holes mate with the plurality of arc-shaped elongated holes and are connected by a fourth bolt.

[0009] Furthermore, the other end of the connecting steel plate is provided with multiple rows of third bolt holes, and the second wooden beam is provided with a groove and a second through hole that mates with the third bolt holes. The other end of the connecting steel plate is inserted into the groove and connected to the second wooden beam through a fifth bolt that passes through the second through hole and the corresponding third bolt hole.

[0010] Furthermore, after the first wooden beam and the second wooden beam are connected to the T-shaped steel plate connector, adhesive is filled into the first through hole, the groove and the second through hole respectively, and then the first bolt and the fifth bolt are tightened.

[0011] The present invention has at least the following beneficial effects:

[0014] Third, the wooden beam connection nodes of the present invention can also be simplified and adjusted according to the accuracy requirements of the actual project. For example, if it is only necessary to reduce the accuracy requirements of the vertical height and horizontal angle, the arc-shaped holes on the connecting steel plate and the transition steel plate and the elliptical long holes on the wedge-shaped steel plate can be eliminated, and only the long oval hole in the center of the wedge-shaped steel plate can be retained, and the wooden components can be directly connected by the transition steel plate.

[0025] like Figures 1-6 As shown, the present invention provides a bidirectional rotatable and bidirectional movable wooden beam connection node, comprising: a first wooden beam 1, a second wooden beam 2, and a T-shaped steel plate connector, wherein the first wooden beam 1 and the second wooden beam 2 are connected by the T-shaped steel plate connector; wherein the T-shaped steel plate connector comprises a wedge-shaped steel plate 3, a transition steel plate 4, and a connecting steel plate 5, wherein the wedge-shaped steel plate 3 is connected to the first wooden beam 1, the transition steel plate 4 intersects with and is rotatably connected to the wedge-shaped steel plate 3, the connecting steel plate 5 is parallel to the transition steel plate 4, and one end of the connecting steel plate 5 is rotatably connected to the transition steel plate 4, and the other end is connected to the second wooden beam 2.

[0026] In the above embodiments, the first wooden beam 1 and the second wooden beam 2 can be made of glued laminated timber or logs. The first wooden beam 1 and the second wooden beam 2 are located in the same plane and are connected by a T-shaped steel plate connector. The T-shaped steel plate connector includes a wedge-shaped steel plate 3, a transition steel plate 4, and a connecting steel plate 5, such as... Figure 1 As shown, the length direction of the first wooden beam 1 is defined, that is... Figure 1 The vertical direction is the horizontal direction, and the width direction of the wedge-shaped steel plate 3 is... Figure 1 The front-to-back direction is vertical. The wedge-shaped steel plate 3 can move horizontally (the length direction of the first wooden beam) and is connected to the first wooden beam 1 by bolts or screws. The transition steel plate 4 intersects with the wedge-shaped steel plate 3. The connecting steel plate 4 can move vertically (i.e., the width direction of the wedge-shaped steel plate 3) and rotate horizontally. The connecting steel plate 5 is parallel to the transition steel plate 4, and one end of the connecting steel plate 5 is vertically rotatably connected to the transition steel plate 4, while the other end is connected to the second wooden beam 2 by bolts or screws. The T-shaped steel plate connector allows for bidirectional rotation and movement during installation, enabling adjustments to the rotation angle and movement distance based on actual engineering precision. This achieves a connection between the wooden beam and the T-shaped steel plate connector in the same plane. Therefore, the wooden beam connection node of this invention has a high tolerance for errors in component manufacturing and structural installation, reducing the requirements for component manufacturing and installation precision and facilitating assembly.

[0027] In another embodiment, the wedge-shaped steel plate 3 is provided with a plurality of elliptical elongated holes 6, each elliptical elongated hole 6 being arranged along the length direction of the first wooden beam 1. Preferably, the plurality of elliptical elongated holes 6 are respectively provided on both sides of the wedge-shaped steel plate 3. The first wooden beam 1 is provided with a first through hole that mates with the elliptical elongated holes 6. The wedge-shaped steel plate 3 and the first wooden beam 1 are connected by a first bolt 7 passing through the elliptical elongated holes 6 and the first through hole. The elliptical elongated holes enable the wedge-shaped steel plate to move in the horizontal direction, and the elliptical elongated holes, the first through hole, and the first bolt enable the connection between the wedge-shaped steel plate and the first wooden beam.

[0028] In another embodiment, the wedge-shaped steel plate 3 has a protruding central portion and a circular slot, which is positioned along the width of the wedge-shaped steel plate 3. The two ends of the circular slot are internally threaded, and a long, narrow opening penetrating the sidewall of the circular slot is located on the side of the circular slot away from the wedge-shaped steel plate 3. A cylindrical connector 8 is fixed to one end of the transition steel plate 4. The transition steel plate 4 and the wedge-shaped steel plate 3 are rotatably connected via the cylindrical connector 8 inserted into the circular slot and secured by a second bolt 9 threaded to the internal threads. The circular slot and cylindrical connector enable the transition steel plate to move vertically and rotate horizontally. After the movement distance and rotation angle of the transition steel plate are adjusted, the second bolt secures the transition steel plate.

[0029] In another embodiment, the transition steel plate 4 has a central hole 10 and multiple arc-shaped elongated holes 11, which are arranged in an equally spaced array around the central hole 10. One end of the connecting steel plate 5 has a first bolt hole and multiple second bolt holes. The first bolt hole mates with the central hole 10 and is connected by a third bolt 12. The multiple second bolt holes mate with the multiple arc-shaped elongated holes 11 and are connected by a fourth bolt 13. Vertical rotation of the connecting steel plate is achieved through the central hole and the arc-shaped elongated holes.

[0030] In another embodiment, the other end of the connecting steel plate 5 is provided with multiple rows of third bolt holes 14, and the second wooden beam 2 is provided with a groove and a second through hole that mates with the third bolt holes 14. The other end of the connecting steel plate 5 is inserted into the groove and connected to the second wooden beam 2 by a fifth bolt 15 passing through the second through hole and the corresponding third bolt hole 14. The bolted connection between the connecting steel plate and the second wooden beam is achieved through the groove, the second through hole, the third bolt holes, and the fifth bolt.

[0031] In another embodiment, after the first wooden beam 1 and the second wooden beam 2 are connected to the T-shaped steel plate connector, adhesive 16 is filled into the first through hole, the groove, and the second through hole, respectively, and then the first bolt 7 and the fifth bolt 15 are tightened. By filling the first through hole, the groove, and the second through hole with adhesive, the connection stability between the first wooden beam and the second wooden beam and the T-shaped steel plate connector is improved.

[0032] The following is a description of a specific embodiment.

[0033] Example 1

[0034] like Figures 1-4 As shown, a bidirectional rotatable and bidirectional movable wooden beam connection node is provided. A first through hole is formed on the first wooden beam 1, and a slot and a second through hole are formed on the second wooden beam 2. A T-shaped steel plate connector is fixed to the first wooden beam 1 by a first bolt 7 and adhesive 16. The T-shaped steel plate connector is connected to the second wooden beam 2 by a fifth bolt 15 and adhesive 16. The T-shaped steel plate connector consists of a wedge-shaped steel plate 3, a transition steel plate 4, and a connecting steel plate 5. The wedge-shaped steel plate 2 has a circular slot with internal threads at both ends along its width in the middle. Multiple elliptical elongated holes 6 are formed on both sides of the wedge-shaped steel plate 3. The transition steel plate 4 has a central hole 10 and multiple arc-shaped elongated holes 11. The connecting steel plate 5 has multiple rows of third bolt holes 14.

[0035] The installation steps are as follows: First wooden beam is installed in place → T-shaped steel plate connector is installed → Second wooden beam is installed. By adjusting the position and angle of each part of the T-shaped steel plate connector, it is ensured that the connecting steel plate 5 can be inserted into the groove of the second wooden beam and that the third bolt hole on the connecting steel plate and the second through hole on the second wooden beam can easily allow the fifth bolt 15 to pass through → Tighten the fourth bolt 13 → After all wooden components are installed in place, adhesive is added to the first through hole, groove and second through hole, and the remaining bolts are tightened → Installation is complete.

[0036] Example 2

[0037] like Figures 5-6 As shown, a vertically movable and horizontally rotatable wooden beam connection node is provided. Compared with embodiment 1, this embodiment eliminates the arc-shaped elongated hole 11 on the connecting steel plate 5 and the transition steel plate 4 and the elliptical elongated hole 6 on the wedge-shaped steel plate 1, and provides bolt holes corresponding to the first through hole and the second through hole on the wedge-shaped steel plate 3 and the transition steel plate 4 respectively.

[0038] The installation steps are as follows: First wooden beam is installed in place → T-shaped steel plate connector is installed → Second wooden beam is installed. The position and angle of the transition steel plate 4 on the T-shaped steel plate connector are adjusted to ensure that the transition steel plate 4 can be inserted into the groove of the second wooden beam and that the bolt holes on the transition steel plate 4 and the second through hole on the second wooden beam can be easily pierced by the fifth bolt 15 → After all wooden components are installed in place, adhesive is added to the first through hole, the groove and the second through hole, and the bolts are tightened → Installation is complete.

[0039] The number of devices and processing scale described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the bidirectional rotatable and bidirectional movable wooden beam connection nodes of the present invention will be readily apparent to those skilled in the art.

[0040] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
