Description

Technical Field

[0001] This utility model relates to the field of timber splicing technology, and in particular to a size-adjustable and recyclable waste timber splicing component. Background Technology

[0002] Construction projects require a large amount of building timber for formwork systems, reinforcement measures, and decoration. Due to factors such as daily management, usage, and natural depreciation, the materials become worn and damaged. Furthermore, to accommodate different structural parts, timber is often cut shorter than it should be, making it difficult to reuse multiple times. To save materials and improve timber utilization, existing methods involve splicing scrap timber, typically using glue. This involves processing the ends of the scrap timber into a serrated shape and then gluing them firmly, or directly smoothing the ends and then gluing them together. However, this method requires processing the timber ends, and the bonding effect is difficult to guarantee, resulting in lower overall load-bearing capacity of the spliced ​​timber. Additionally, the use of glue does not conform to the concept of green environmental protection. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-5 and Figure 7 This is the first embodiment of the present invention, which provides a reusable and adjustable-size scrap timber splicing component. The component includes a lower steel plate 1, on which an upper steel plate 2 is slidably mounted. The lower steel plate 1 has a sliding groove 1-1, and the upper steel plate 2 has a circular hole 2-1. A screw 3 is inserted into the circular hole 2-1. The lower steel plate 1 and the upper steel plate 2 are similarly U-shaped and their shapes match each other. The widths of the lower steel plate 1 and the upper steel plate 2 are the same, matching the width of the scrap timber 16. They can slide relative to each other. When splicing the scrap timber 16, two scrap timbers 16 are first joined together, and then the lower steel plate 16 is spliced... The steel plate 1 is fitted onto the lower end of the two square timbers 16 near the joint. The lower end of the square timbers 16 is in contact with the end face of the steel plate 1. Then, the upper steel plate 2 is snapped into place from above, with the upper end face of the square timbers 16 in contact with the inner top wall of the upper steel plate 2. This allows the lower steel plate 1 and the upper steel plate 2 to adjust their relative height according to the different heights of the square timbers 16. Then, the screw 3 is inserted into the round hole 2-1, passes through the sliding groove 1-1, and is screwed into the inside of the square timbers 16, making the screw 3 fit tightly with the lower steel plate 1. This locks the positions of the square timbers 16, the lower steel plate 1, and the upper steel plate 2. The rigid structure, combined with the screw 3, reinforces the joint and ensures the strength and safety of the load.

[0028] A cylinder 4 is fixed on the upper steel plate 2, and a fixed column 5 is fixed on the lower steel plate 1. A rotating plate 6 is rotatably connected to the fixed column 5. An extension plate 7 is slidably arranged inside the rotating plate 6. A slide rail 8 is fixed on the extension plate 7. An arc groove 8-1 is opened on the slide rail 8. The cylinder 4 can slide in the arc groove 8-1. One end of the arc groove 8-1 is provided with an opening. The center of the arc of the arc groove 8-1 does not coincide with the center of the fixed column 5. The extension plate 7 slides in the rotating plate 6, so that the distance between the slide rail 8 and the fixed column 5 can be changed, thereby adapting to square timber 16 of different heights.

[0029] After the upper steel plate 2 and the lower steel plate 1 are engaged near the joints of the two square timbers 16, adjust the position of the extension plate 7 within the rotating plate 6 so that when the rotating plate 6 is pushed to rotate, it drives the slide rail 8 to rotate and gradually approach the cylinder 4. Then, the cylinder 4 can enter the arc groove 8-1 from the opening position. After that, the rotating plate 6 continues to rotate. Since the arc center of the arc groove 8-1 does not coincide with the center of the fixed column 5, when the slide rail 8 rotates with the fixed column 5 as the center, the highest point of the arc groove 8-1 will gradually decrease, and the cylinder 4 will slide within the arc groove 8-1. The arc groove 8-1 applies a downward pushing force to the cylinder 4, making the upper steel plate 2 and the lower steel plate 1 fit more tightly. The two will then fit together synchronously with the middle square timber 16, thereby strengthening the connection.

[0030] Example 2 Reference Figures 4-6This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the lower steel plate 1 and the upper steel plate 2 together form a cavity 1-2. The square timber 16 is inserted into the cavity 1-2. The width of the steel plate 1 and the upper steel plate 2 can be customized according to the square timber 16 of different widths. The width of the cavity 1-2 is fixed, while the height of the cavity 1-2 can be adjusted according to the square timber 16 of different heights.

[0032] Specifically, there are four sliding grooves 1-1 and four round holes 2-1, and four screws 3 in total. When the cylinder 4 enters the arc groove 8-1 and the rotating plate 6 is rotated, the screws 3 can be inserted into the round holes 2-1 and the sliding grooves 1-1, screwed into the inside of the square timber 16, and tightly fitted with the outer end face of the lower steel plate 1, thereby locking the relative positions of the upper steel plate 2, the lower steel plate 1, and the square timber 16.

[0033] Specifically, the rotating plate 6 has a threaded groove, and a bolt 9 is threadedly connected to the rotating plate 6. The rotating plate 6 also has a lifting groove 6-1 corresponding to the extension plate 7. The extension plate 7 slides in the lifting groove 6-1, and the bolt 9 is threadedly connected to the threaded groove. The end face of the bolt 9 will gradually come into contact with the end face of the extension plate 7. Under the action of friction, the position of the extension plate 7 in the lifting groove 6-1 will be locked, thereby locking the distance between the slide rail 8 and the fixed column 5, so as to adapt to the splicing of square timber 16 of different heights.

[0034] Specifically, a pressure plate 10 is fixed on the rotating plate 6. A handle 11 is rotatably connected to one side of the pressure plate 10. The pressure plate 10 is relatively long. The rotatable connection between the handle 11 and the pressure plate 10 is damped. Only when a certain external force is applied can the two rotate relative to each other. When it is necessary to rotate the rotating plate 6, the handle 11 is rotated to make it perpendicular to the pressure plate 10 for easy operation. When it is not in use, the handle 11 can be rotated to make the handle 11 parallel to the pressure plate 10 to reduce the space occupied.

[0035] When the cylinder 4 enters the interior through the opening of the arc groove 8-1, and it is necessary to further compress the upper steel plate 2 and the lower steel plate 1, the pressure plate 10 is rotated downward by pressing down the handle 11, which can easily drive the rotating plate 6 to rotate around the fixed column 5, thus saving effort.

[0036] Example 3 Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, a moving groove 10-1 is provided in the pressure plate 10, and a locking block 12 is slidably disposed in the moving groove 10-1. The locking block 12 also slides in the rotating plate 6. A corresponding locking groove 5-1 is provided on the fixed column 5. The locking block 12 is rectangular, and the locking groove 5-1 is of a corresponding shape. When the locking block 12 engages with the locking groove 5-1, the rotation of the rotating plate 6 around the fixed column 5 will be restricted, thereby locking the position of the slide rail 8 relative to the cylinder 4, and thus locking the relative position of the lower steel plate 1 and the upper steel plate 2, so as to facilitate the subsequent screwing in of the screw 3 to complete the final locking.

[0038] Specifically, a spring 13 is fixed to one end of the locking block 12, and the other end of the spring 13 is fixed to the inner wall of the moving groove 10-1. The spring 13 ensures that the locking block 12 always tends to move towards the locking groove 5-1, thus ensuring that the locking block 12 can contact the locking groove 5-1.

[0039] Specifically, there are multiple locking slots 5-1. By setting multiple locking slots 5-1, the rotating plate 6 can be locked at multiple angles.

[0040] Specifically, a pull plate 14 is fixed to one side of the locking block 12. The pull plate 14 is L-shaped. The pressure plate 10 has a sliding groove 9-2 corresponding to the pull plate 14. The pull plate 14 is designed to release the movement of the locking block 12 and the locking groove 5-1. When it is necessary to rotate the rotating plate 6, the pull plate 14 is pulled first to compress the spring 13, thereby moving the locking block 12 away from the locking groove 5-1. When the two are completely separated, the rotating plate 6 can rotate around the fixed column 5.

[0041] Specifically, a guide post 15 is fixed inside the slide groove 9-2, and a corresponding guide groove 14-1 is opened on the pull plate 14. Through the cooperation of the guide post 15 and the guide groove 14-1, the pull plate 14 can be smoothly slid inside the slide groove 9-2.

[0042] In use, first, put the two square timbers 16 together, then put the lower steel plate 1 on the lower end near the joint of the two square timbers 16, with the lower end of the square timber 16 in contact with the end face of the steel plate 1. Then, from above, snap the upper steel plate 2 into place with the lower steel plate 1, with the upper end face of the square timber 16 in contact with the inner top wall of the upper steel plate 2. Adjust the position of the extension plate 7 in the rotating plate 6 so that when the rotating plate 6 is pushed to rotate, it drives the slide rail 8 to rotate and gradually approach the cylinder 4. Tighten the bolts 9 to lock the position of the extension plate 7 in the lifting groove 6-1, thereby locking the distance of the slide rail 8 relative to the fixed column 5, so as to adapt to the extension of square timbers 16 of different heights.

[0043] Then, pulling the pull plate 14 compresses the spring 13, causing the locking block 12 to move away from the locking groove 5-1. This pushes the rotating plate 6 to rotate. Once the cylinder 4 enters the interior through the opening of the arc-shaped groove 8-1, pressing down the handle 11 causes the pressure plate 10 to rotate downwards, easily rotating the rotating plate 6 around the fixed post 5. Because the center of the arc of the arc-shaped groove 8-1 does not coincide with the center of the fixed post 5, as the slide rail 8 rotates around the fixed post 5, the highest point of the arc-shaped groove 8-1 gradually decreases, while the cylinder 4 slides on the arc-shaped groove. Inside the groove 8-1, the arc-shaped groove 8-1 applies a downward pushing force to the cylinder 4, thereby making the upper steel plate 2 and the lower steel plate 1 fit more tightly together. The two will then fit more tightly with the square timber 16 in the middle, thereby strengthening the connection. Then, the pull plate 14 is released, and the spring 13 returns to its original position, causing the locking block 12 to engage with the locking groove 5-1. The rotation of the rotating plate 6 around the fixed column 5 will be restricted, thereby locking the position of the slide rail 8 relative to the cylinder 4, and further locking the relative position of the lower steel plate 1 and the upper steel plate 2, thus facilitating the subsequent screwing in of the screw 3 to complete the final locking.

[0044] Finally, screw 3 is inserted into the round hole 2-1, passes through the sliding groove 1-1, and is screwed into the inside of the square timber 16, so that screw 3 fits tightly with the end face of the lower steel plate 1, thereby locking the position of the square timber 16, the lower steel plate 1, and the upper steel plate 2. The joint strength and stress safety are ensured by the rigid structure and the screw 3 for reinforcement.

[0045] To disassemble, simply unlock the rotating plate 6, flip it away from the cylinder 4, and then remove the screws 3 to complete the disassembly. It can be reused in the future.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
