Technical Field

[0001] This utility model relates to the field of plastic timber technology, and in particular to a plastic timber assembly structure for power tunnel well construction. Background Technology

[0002] With the continuous advancement of urban power grid construction, the scale and complexity of power tunnel shaft construction are increasing daily. Plastic-coated timber, due to its lightweight, corrosion resistance, ease of transportation and storage, and reusability, is widely used in power tunnel shaft construction, becoming an important material for constructing temporary support structures and formwork systems. However, the structural designs of power tunnel shafts are diverse, and during construction, plastic-coated timber often needs to be spliced ​​in different ways according to actual working conditions to meet complex spatial layouts and stress requirements.

[0003] Currently, most of the plastic timber assembly structures commonly used in power tunnel construction adopt a simple plug-in structure. However, the traditional plug-in structure is limited, and it can only be spliced ​​horizontally. Therefore, it cannot be flexibly adjusted according to different assembly requirements. Thus, there is a need for a splicing structure that can be spliced ​​both horizontally and vertically. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a plastic square timber assembly structure for power tunnel well construction. This structure can solve the problem that the traditional plug-in structure is simple and mostly allows plastic square timber to be spliced ​​in the horizontal direction, thus it cannot flexibly adjust the assembly structure of plastic square timber according to different assembly requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic square timber assembly structure for power tunnel shaft construction, comprising a first plastic square timber and a second plastic square timber. A butt groove is provided on one side of the second plastic square timber, and a splicing component is provided on one side of the first plastic square timber. The splicing component includes a butt block, one end of which is fixedly connected to one end of the first plastic square timber. The outer surface of the butt block is slidably connected to the inner wall of the butt groove. Rotating columns are fixedly connected to both ends of the butt block. A first threaded groove is provided on the opposite ends of the two rotating columns. Positioning grooves are provided on both sides of the inner wall of the butt groove, and the interiors of the two positioning grooves are slidably connected to the surfaces of the corresponding rotating columns.

[0006] Preferably, the second plastic square timber has a second threaded groove on both sides, and the interior of the two second threaded grooves is connected to the interior of the corresponding positioning groove.

[0007] Preferably, the inner walls of the two second threaded grooves are threaded with fixing bolts, and the opposite ends of the two fixing bolts are respectively threaded with the inner threads of the corresponding first threaded grooves.

[0008] Preferably, a through groove is formed on one side of the first plastic square timber, and a sliding block is slidably connected to the inner wall of the through groove. A snap-fit ​​groove is formed on one side of the sliding block.

[0009] Preferably, a slot is provided on one side of the second plastic square timber, and the interior of the slot is slidably adapted to the surface of the sliding block.

[0010] Preferably, a limiting groove is formed on the bottom surface of the inner wall of the through groove, and a limiting block is slidably connected inside the limiting groove, with the top end of the limiting block slidably connected to the bottom end of the sliding block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The plastic square timber assembly structure for power tunnel shaft construction uses rotating columns to slide along the positioning slots on both sides of the docking groove until the docking block is fully inserted into the docking groove. This facilitates the horizontal splicing of the first and second plastic square timbers. At the same time, the two rotating columns drive the docking block to rotate, which facilitates the vertical splicing of the first plastic square timber on one side of the second plastic square timber. This allows for flexible adjustment and assembly of the plastic square timber according to different assembly requirements, further improving the practicality of the plastic square timber.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a plastic square timber assembly structure for power tunnel shaft construction, including a first plastic square timber 1 and a second plastic square timber 2. A butt joint groove 6 is provided on one side of the second plastic square timber 2. A splicing component is provided on one side of the first plastic square timber 1. The splicing component includes a butt joint block 3. One end of the butt joint block 3 is fixedly connected to one end of the first plastic square timber 1. The outer surface of the butt joint block 3 is slidably connected to the inner wall of the butt joint groove 6. Rotating columns 4 are fixedly connected to both ends of the butt joint block 3. A first threaded groove 5 is provided at the opposite ends of the two rotating columns 4. Positioning grooves 7 are provided on both sides of the inner wall of the butt joint groove 6. The interior of the two positioning grooves 7 is slidably connected to the surface of the corresponding rotating column 4.

[0023] Furthermore, the second plastic square timber 2 has second threaded grooves 8 on both sides. The interior of the two second threaded grooves 8 is connected to the interior of the corresponding positioning grooves 7. The inner walls of the two second threaded grooves 8 are threaded with fixing bolts 9. The opposite ends of the two fixing bolts 9 are threaded with the interior of the corresponding first threaded grooves 5.

[0024] Furthermore, a through groove 11 is opened on one side of the first plastic square timber 1, and a sliding block 14 is slidably connected to the inner wall of the through groove 11. A buckle groove 15 is opened on one side of the sliding block 14.

[0025] Furthermore, a slot 10 is provided on one side of the second plastic square timber 2, and the interior of the slot 10 is slidably adapted to the surface of the sliding block 14.

[0026] Furthermore, a limiting groove 12 is formed on the bottom surface of the inner wall of the through groove 11, and a limiting block 13 is slidably connected inside the limiting groove 12. The top end of the limiting block 13 is slidably connected to the bottom end of the sliding block 14.

[0027] Furthermore, when splicing the first plastic square timber 1 and the second plastic square timber 2, the first plastic square timber 1 is first slidably inserted into the docking groove 6 on one side of the second plastic square timber 2 with the docking block 3 attached, so that the docking block 3 can be smoothly moved into the interior of the docking groove 6. Then, during the insertion of the docking block 3, the rotating columns 4 at both ends of the docking block 3 slide along the positioning grooves 7 on both sides of the inner wall of the docking groove 6 until the docking block 3 is fully inserted into the docking groove 6, and the first plastic square timber 1 and the second plastic square timber 2 complete the initial splicing.

[0028] Furthermore, after the docking block 3 and the docking groove 6 are spliced, the first threaded grooves 5 on both sides of the rotating column 4 are aligned with the second threaded grooves 8 on both sides of the second plastic square timber 2. Then, the two fixing bolts 9 are rotated so that the opposite ends of the two fixing bolts 9 are connected to the internal threads of the corresponding first threaded grooves 5. This allows the two rotating columns 4 to be fixed inside the two positioning grooves 7, thereby tightly fixing the first plastic square timber 1 and the second plastic square timber 2 together, enhancing the stability of the assembly structure and ensuring that it will not easily loosen during the construction of the power tunnel shaft.

[0029] Furthermore, when it is necessary to vertically splice and adjust the first plastic square timber and the second plastic square timber 2, firstly, unscrew the two fixing bolts 9 from the corresponding first threaded grooves 5, so that the two rotating columns 4 lose their fixing force inside the two positioning grooves 7. Then, the first plastic square timber 1 can be rotated, and the two rotating columns 4 will drive the connecting block 3 to rotate, so that the first plastic square timber 1 is perpendicular to one side of the second plastic square timber 2. At the same time, the through groove 11 is located above the slot 10 and directly facing the inside of the slot 10. Then, tighten the two fixing bolts 9 again, so that the two fixing bolts 9 are reconnected to the internal threads of the corresponding first threaded grooves 5. At this point, the first plastic square timber 1 and the second plastic square timber 2 can be initially vertically spliced. Then, the sliding block 14 is slid down and inserted into the slot 10 using the buckle groove 15, so that the first plastic square timber 1 and the second plastic square timber after vertical splicing are limited, thereby improving the stability of the first plastic square timber 1 and the second plastic square timber 2 after vertical splicing, thereby improving the stability of the entire splicing structure.

[0030] Furthermore, by allowing the limiting block 13 to slide within the limiting groove 12, the sliding direction and range of the sliding block 14 can be restricted, thereby making the movement of the sliding block 14 more stable.

[0031] Furthermore, by rotating the column 4 and sliding it along the positioning grooves 7 on both sides of the inner wall of the docking groove 6 until the docking block 3 is fully inserted into the docking groove 6, it is convenient to horizontally splice the first plastic square timber 1 and the second plastic square timber 2. At the same time, the two rotating columns 4 will drive the docking block 3 to rotate, which makes it convenient to vertically assemble the first plastic square timber 1 on one side of the second plastic square timber 2. Thus, the plastic square timber can be flexibly adjusted and assembled according to different assembly requirements, which further improves the practicality of the plastic square timber.
