Description

Technical Field

[0001] This utility model relates to the field of connection component technology, and in particular to a steel-wood connection component for traditional building repair. Background Technology

[0002] Steel-wood connection is a key technology for combining steel and wood. It mainly uses metal connectors to achieve a firm bond between the two materials, including bolt connections, screw connections, and sleeve connections. It is commonly used in construction, furniture and other fields. In the use of steel and wood, steel provides strength and stability, while wood can reduce the overall weight. In addition, the wood fibers inside the wood have excellent shock absorption properties.

[0003] In existing steel-wood connection structures, the wooden beams are mainly fixed to the steel beams using tee or cross sleeves and fastening bolts. Especially in the field of traditional building restoration, using steel beams as support beams can improve the structural strength of the building and ensure its long-term use after restoration. Wooden beams can further restore the structural details of traditional buildings. However, after the building is restored, due to the difference in strength between steel and wood, the steel-wood connection point bears the greatest load when encountering vibrations (such as impacts to the steel beams or strong winds). Furthermore, the wooden beams are prone to shaking inside the sleeves. The continuous shaking of the wooden beams can cause the fastening bolts to loosen, or even cause the wooden beams to fall off, posing certain safety hazards. Moreover, if the wooden beams need to be replaced during later maintenance, the wooden beams, being fixed to the sleeves for a long time, can become stuck inside the sleeves, making it difficult to remove them and increasing the difficulty of maintenance. Therefore, a steel-wood connection component for traditional building restoration is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel-wood connection component for traditional building repair. It has the advantages of buffering vibrations to wooden beams, improving the stability of steel-wood connections, increasing the bonding strength between the wooden beam and the transverse sleeve when the wooden beam is subjected to vibration, preventing the wooden beam from loosening, and facilitating the disassembly and maintenance of the wooden beam. This solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a steel-wood connection component for traditional building repair, comprising a main sleeve, a transverse sleeve, and fastening screws. The transverse sleeve is fixedly connected to the middle of the outer surface of the main sleeve. An upper steel beam and a lower steel beam are fixedly connected to the inside of the main sleeve via fastening screws. A wooden beam is fixedly connected to the inside of the transverse sleeve via fastening screws. A buffer device is provided inside the wooden beam. A fastening device is provided on the buffer device. The buffer device includes a slot. The slot is opened on the end face of the wooden beam located inside the transverse sleeve. A rubber damper for buffering the vibration of the wooden beam is fixedly connected inside the slot. An inclined groove for easy clamping is opened on the outer surface of the wooden beam located inside the transverse sleeve.

[0006] Preferably, the fastening device includes a locking block, which is fixedly connected to the end face of the rubber damper away from the wooden beam. A bolt for fastening is rotatably connected to the middle of the end face of the rubber damper away from the wooden beam, and the outer surface of the bolt is provided with thread one and thread two.

[0007] Preferably, the outer surface of the bolt is fitted with a connecting plate for support at the second thread, and the upper and lower ends of the connecting plate are fixedly connected with wedges for fastening. The upper and lower end faces of the locking block are provided with clearance grooves to facilitate the movement of the wedges.

[0008] Preferably, the dimensions of the inclined groove and the wedge are matched, the first thread and the second thread have opposite directions of rotation, and the bolt is connected to the side wall of the main sleeve through the first thread.

[0009] Preferably, the end of the bolt away from the main sleeve is connected to a valve core structure via a thread.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the design of rubber dampers, inclined grooves, locking blocks, and bolts, allows for the buffering of vibrations during use by installing rubber dampers inside the wooden beams, especially in the event of vibrations or strong winds. Simultaneously, the rubber dampers expand under the pressure of the wooden beams, applying outward tension and ensuring the beams adhere tightly to the inner wall of the transverse sleeve. Furthermore, the deformation of the rubber dampers applies pressure to the locking blocks, causing them to engage with the wedges through the clearance grooves, thus stabilizing the wedges' position at the inclined grooves and improving the stability of the wooden beams.

[0011] 2. This utility model, through the design of bolts, thread one, thread two, connecting plates, and wedges, allows for the following installation process: by rotating the bolt clockwise, the bolt moves outward from the main sleeve. At this time, the bolt pulls the locking block to move synchronously, causing the clearance groove on the locking block to lock with the wedge. Simultaneously, since thread two is in the opposite direction to thread one, as the bolt moves outward from the main sleeve, the connecting plate moves in the opposite direction to the bolt. This causes the wedge to move towards the inclined groove, thereby locking the wooden beam and preventing it from loosening.

[0012] 3. When the wooden beam needs to be removed for maintenance, press the guide rod to release the gas inside the rubber damper. Then, turn the bolt counterclockwise to move the bolt towards the inside of the main sleeve. At this time, the threaded plate will move in the opposite direction with the connecting plate, and the connecting plate will move synchronously with the wedge, causing the wedge to leave the inclined groove. During the movement, the bolt will push against the locking block, thereby using the thrust of the bolt against the locking block to push the wooden beam out of the transverse sleeve, making it easier to remove the wooden beam and reducing the difficulty of maintenance. After maintenance, the gas can be refilled into the rubber damper through the valve core structure to make the wooden beam clamped on the transverse sleeve. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6A steel-wood connection assembly for traditional building repair includes a main sleeve 1, a transverse sleeve 2, and fastening screws 3. The transverse sleeve 2 is fixedly connected to the middle of the outer surface of the main sleeve 1. A reinforcing rib 4 is fixedly connected between the main sleeve 1 and the transverse sleeve 2. Two symmetrically positioned limiting plates 5 are fixedly connected inside the main sleeve 1. An upper steel beam 6 and a lower steel beam 7 are fixedly connected inside the main sleeve 1 via the fastening screws 3. The upper steel beam 6 and lower steel beam 7 are fixed to the main sleeve 1 via the fastening screws 3 to form a main beam, which improves the strength and stability of the building. The upper steel beam 6 is located above the upper limiting plate 5, and the lower steel beam 7 is located below the lower limiting plate 5. A wooden beam 8 is fixedly connected inside the transverse sleeve 2 via the fastening screws 3. The design of the wooden beam 8 reduces the overall weight of the building. The wooden beam 8 has internal... The device includes a buffering device with a fastening mechanism. The buffering device includes a slot 81, which is located on the end face of the wooden beam 8 inside the transverse sleeve 2. A rubber damper 82 for buffering the vibration of the wooden beam 8 is fixedly connected inside the slot 81. The rubber damper 82 is composed of a rubber material in the middle and hard steel plates on both sides. When the wooden beam 8 is vibrated, the vibration is transmitted to the rubber damper 82, and then the rubber damper 82 is compressed and expanded. The expanded rubber damper 82 also applies pressure to the wooden beam 8 while buffering the vibration, so that an outward tension is formed inside the wooden beam 8. Under the action of the outward tension, the wooden beam 8 will fit tightly with the transverse sleeve 2 to improve the stability of the wooden beam 8. An inclined groove 83 is provided on the outer surface of the wooden beam 8 inside the transverse sleeve 2 for easy clamping.

[0017] Please see Figure 2 and Figure 3 The fastening device includes a locking block 84, which is fixedly connected to the end face of the rubber damper 82 away from the wooden beam 8. This ensures that the rubber damper 82 can apply pressure to the locking block 84 after it expands due to vibration. A bolt 85 for fastening is rotatably connected to the middle of the end face of the rubber damper 82 away from the wooden beam 8. The bolt 85 is connected to the hard steel plate of the rubber damper 82 through a ball bearing to facilitate the rotation of the bolt 85. The outer surface of the bolt 85 is provided with a thread 1 86 and a thread 2 87. A square hole for the bolt 85 to pass through is opened in the middle of the locking block 84, ensuring that when the bolt 85 moves through the thread 1 86, the bolt 85 can pull the locking block 84 to move synchronously while rotating.

[0018] Please see Figure 3 and Figure 4The outer surface of bolt 85 is connected to a connecting plate 88 for support at thread 87. Both the upper and lower ends of the connecting plate 88 are fixedly connected to wedges 89 for fastening. The upper and lower end faces of the locking block 84 are provided with clearance grooves 841 to facilitate the movement of the wedges 89, ensuring that the wedges 89 can fit tightly against the inclined groove 83, so that the wooden beam 8 and the transverse sleeve 2 form an interference fit, thereby fixing the wooden beam 8 on the transverse sleeve 2, which improves the stability of the wooden beam 8 and prevents the wooden beam 8 from loosening.

[0019] Please see Figure 3 The dimensions of the inclined groove 83 and the wedge 89 are matched. The threads 86 and 87 are opposite in direction. The bolt 85 is connected to the side wall of the main sleeve 1 through the thread 86. When the bolt 85 moves using the thread 86, the connecting plate 88 connected to the bolt 85 through the thread 87 can move in the opposite direction of the bolt 85. Then, the connecting plate 88 moves the wedge 89 synchronously, so as to achieve the engagement and separation of the wedge 89 and the inclined groove 83.

[0020] Please see Figure 4 and Figure 5 The end of bolt 85 away from the main sleeve 1 is connected to valve core structure 851 by thread.

[0021] Please see Figure 6 The valve core structure 851 has an internal gas groove 852, a stepped groove 853 and a conical groove 854 for gas transmission. The gas groove 852 and the conical groove 854 are connected through the stepped groove 853.

[0022] Please see Figure 6 A spring 855 for resetting is fixedly connected inside the stepped groove 853. A stopper 856 for sealing the conical groove 854 is fixedly connected to one end of the spring 855 facing the conical groove 854. A guide rod 857 for venting is fixedly connected to the middle of the end face of the stopper 856 facing the spring 855. The side wall of the stopper 856 fits against the inner wall of the conical groove 854, ensuring that the stopper 856 moves synchronously with the guide rod 857 when it moves. Then, the spring 855 is used to reset the stopper 856, and the movement of the stopper 856 is used to open and close the conical groove 854.

[0023] Please see Figure 5 and Figure 6The bolt 85 has an internal slot 858 for gas transmission. The opening of the slot 858 near the valve core structure 851 communicates with the conical groove 854, and the opening of the slot 858 away from the valve core structure 851 communicates with the rubber damper 82. When venting is required, simply press the guide rod 857, causing the guide rod 857 to move towards the slot 858 along with the stopper 856. At this time, the stopper 856 no longer blocks the conical groove 854, allowing the gas inside the rubber damper 82 to pass through. The gas is discharged sequentially through the through groove 858, the conical groove 854, the stepped groove 853 and the air groove 852, thus releasing the gas from the rubber damper 82. When inflation is required, the inflation device (such as an air cylinder or air pump) is connected to the valve core structure 851, and then the rubber damper 82 is inflated. After the rubber damper 82 is fully inflated, the air pressure and the potential energy of the spring 855 cause the stopper 856 to seal the conical groove 854, preventing the gas inside the rubber damper 82 from leaking out.

[0024] Working principle: In use, the upper steel beam 6 and lower steel beam 7 are fixed to the main sleeve 1 by the fastening screw 3, and then the wooden beam 8 is fixed to the transverse sleeve 2 by the fastening screw 3. At this time, the inclined groove 83 on the wooden beam 8 is in contact with the wedge 89. Then, the bolt 85 is rotated clockwise, causing the bolt 85 to move outward from the main sleeve 1. At this time, because the first thread 86 and the second thread 87 have opposite directions of rotation, the connecting plate 88 moves towards the wooden beam 8. The connecting plate 88 moves with the wedge 89, causing the wedge 89 to be stuck in the inclined groove 83. At the same time, the bolt 85 will pull when it moves. As the locking block 84 moves synchronously, the clearance groove 841 on the locking block 84 fits tightly against the wedge block 89, thereby fixing the position of the wedge block 89 and preventing the wooden beam 8 from falling off. When the wooden beam 8 is vibrated, the vibration is transmitted to the rubber damper 82, which buffers the vibration of the wooden beam 8 and prevents the fastening screw 3 on the wooden beam 8 from loosening. At the same time, when the rubber damper 82 is compressed, it applies pressure to the wooden beam 8, causing the wooden beam 8 to generate outward tension, which makes the wooden beam 8 fit tightly against the wedge block 89 through the inclined groove 83, improving the stability of the wooden beam 8. When it needs to be removed for maintenance, first unscrew the fastening screw 3 on the transverse sleeve 2, then press the guide rod 857, causing the guide rod 857 to move with the stop 856 and open the conical groove 854. Then, the gas inside the rubber damper 82 will be discharged through the through groove 858, causing the rubber damper 82 to retract and thus release the pressure applied to the wooden beam 8. Then, turn the bolt 85 counterclockwise. At this time, the bolt 85 moves into the main sleeve 1 through the thread 1 86, while the connecting plate 88 moves in the opposite direction through the thread 2 87. The connecting plate 88 moves synchronously with the wedge block 89, causing the wedge block 89 to move in the opposite direction. As bolt 85 moves away from inclined groove 83 and towards the interior of main sleeve 1, it applies a pushing force to locking block 84, causing the gap between the relief groove 841 and wedge block 89 to loosen. The pushing force acting on locking block 84 pushes wooden beam 8 to move, causing wooden beam 8 to disengage from the position of transverse sleeve 2, thus facilitating the removal of wooden beam 8 and reducing maintenance difficulty. After maintenance, the rubber damper 82 can be inflated through valve core structure 851, causing the rubber damper 82 to expand again and apply pressure to wooden beam 8, causing wooden beam 8 to be locked onto transverse sleeve 2, further improving the stability of wooden beam 8.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
