Description

Technical Field

[0001] This utility model relates to the field of aluminum plate connection, and in particular to an aluminum plate connection structure for the inner formwork of elevator shaft concrete pouring. Background Technology

[0002] With the continuous development of construction technology, the requirements for construction efficiency have become more stringent. In construction, the traditional internal formwork for concrete pouring in elevator shafts is mostly made of wood or steel. Wood formwork is prone to moisture, deformation, and warping, resulting in poor flatness and verticality of the concrete surface, and has a low turnover rate. Steel formwork is heavy, cumbersome to install and dismantle, has low construction efficiency, and also poses safety hazards such as formwork collapse. At the same time, the limited operating space of both wood and steel formwork further increases the difficulty and cost of construction. With the development of the construction industry, aluminum alloy formwork has gradually been applied due to its advantages such as light weight, high rigidity, smooth surface, and reusability.

[0003] In the aluminum plate connection structure of the inner formwork for elevator shaft concrete pouring, a closed inner formwork system is formed by combining high-strength aluminum plates (with reinforcing ribs) with standardized connectors such as angle brackets and bolts. The rigid connection of angle brackets and bolts disperses and transmits the lateral pressure of concrete to the overall structure and external support system. The mechanical compression and secondary sealing of rubber sealing strips and sealant block the leakage channels. The precise positioning and fine adjustment of aluminum plates are achieved by using positioning pin holes and elongated hole bolts to ensure the dimensional accuracy of the shaft. At the same time, the quick-assembly and quick-disassembly design is adopted to adapt to layered pouring. Ultimately, the inner formwork can be quickly assembled, stably stressed, sealed and leak-proof, dimensionally controllable, and reusable.

[0004] The lack of a quick and stable installation structure in existing technologies leads to time-consuming and labor-intensive formwork assembly, poor positioning accuracy, and uneven stress during concrete pouring, resulting in formwork deformation and grout leakage at joints. This not only affects the quality of shaft forming and construction efficiency but may also increase labor costs due to repeated disassembly and adjustment, and even cause safety hazards due to structural instability, making it difficult to meet the high-precision and high-efficiency construction requirements of elevator shafts.

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an aluminum plate connection structure for an inner formwork of an elevator shaft concrete pouring system. The structure includes an elevator aluminum plate 1 and an elevator aluminum plate 2, which are the core materials constituting the inner formwork. After being spliced ​​together by the connection structure, they form a complete pouring cavity. An operating mechanism 3 is installed on the outside of the elevator aluminum plate 1. The operating mechanism 3 is a key component for initially fixing the two aluminum plates, providing basic connection force for splicing. A locking mechanism 4 is installed on the outside of the elevator aluminum plate 2. The locking mechanism 4 is used to strengthen the fixation from the center position, improving the overall connection stability. The operating mechanism 3 includes a fixing block 31, which is the mounting base of the operating mechanism 3, providing stable support for subsequent components. The bottom of the fixing block 31 is fixedly connected to the outside of the elevator aluminum plate 1. This fixing method can transfer the force of the operating mechanism 3 to the aluminum plate, avoiding local stress concentration. The front of the fixing block 31... A connecting ring 32 is fixedly connected to the end of the connecting ring 32. The connecting ring 32 is a bridge connecting the fixed block 31 and other moving parts, enabling force transmission. A fixing bolt 33 is slidably connected to the front end of the connecting ring 32. The fixing bolt 33 can slide within the connecting ring 32, providing a range of motion for the rotation of the connecting block 34. A connecting block 34 is slidably connected to the outside of the fixing bolt 33. The connecting block 34 can be adjusted in position by sliding to adapt to different connection requirements. A fixing bolt 36 is rotatably connected to the outside of the connecting block 34. The rotation of the fixing bolt 36 can drive the connecting rod 37 to move synchronously, realizing the length adjustment function. A connecting rod 37 is fixedly connected to the top of the fixing bolt 36. The connecting rod 37 is a direct component connecting the two aluminum plates. After its position is fixed, a rigid connection can be formed. A limiting component 38 is provided at the front end of the connecting rod 37. The limiting component 38 can limit the connecting rod 37 to prevent it from accidentally detaching.

[0034] The limiting component 38 includes a fixing block 381, which serves as the mounting base for the limiting component 38 and ensures the stability of the buckle plate 382. The bottom of the fixing block 381 is fixedly connected to the outside of the elevator aluminum plate 1. This fixing method allows the limiting component 38 to form an integral unit with the aluminum plate, improving the reliability of the limiting action. The buckle plate 382 is fixedly connected to the outside of the fixing block 381. The slot of the buckle plate 382 can lock the connecting rod 37, achieving mechanical locking. A handle 35 is fixedly connected to the rear end of the connecting block 34. The handle 35 provides a force point for the operator to manually adjust the position of the connecting block 34. The rear side of the handle 35 is movable. A fixing bolt 39 is connected, which can move on the handle 35. At the same time, the connecting chain 310 provides a double safety function. The top of the fixing bolt 39 is fixedly connected to the connecting chain 310, which can limit the excessive rotation of the handle 35 and prevent the connecting rod 37 from coming off. One end of the connecting chain 310 is fixedly connected to the connecting plate 311, which fixes the connecting chain 310 to the fixing block 313, forming a stable constraint structure. Multiple fixing blocks 313 are fixedly connected to the outside of the elevator aluminum plate 1. The fixing blocks 313 provide the installation position for the connecting plate 311 and enhance the fixing effect of the connecting chain 310.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The locking mechanism 4 includes two locking frames 41, which correspond to two aluminum plates respectively, forming a symmetrical locking structure. The bottom of one locking frame 41 is fixedly connected to the outside of the elevator aluminum plate 1, ensuring a stable connection between the locking mechanism 4 and the aluminum plate. Both locking frames 41 have two lock cylinders 43 rotatably connected inside. The rotation of the lock cylinders 43 can change the locking state, realizing the switching between unlocking and locking. The lock cylinders 43 are fixedly connected to the outside of a lever 42. The lever 42 allows the operator to manually adjust the angle of the lock cylinders 43, simplifying the operation process. The lever 42 is slidably connected to the outside of the locking frame 41. This sliding connection can cooperate with the rotation of the lock cylinders 43, while limiting the range of motion of the lever 42.

[0036] Reference Figure 1 and Figure 4The bottom of the connecting plate 311 is fixedly connected to the outside of the fixing block 313, so that one end of the connecting chain 310 is fixed, forming a complete constraint loop. The fixing block 313 has multiple screws 312 on its external thread. The screws 312 firmly fix the fixing block 313 to the aluminum plate through the threaded connection to prevent loosening. The other end of the screws 312 is threadedly connected to the inside of the elevator aluminum plate 1. This double threaded connection can improve the installation strength of the fixing block 313. The outside of the connecting rod 37 contacts the slot of the buckle plate 382. The shape of the slot is adapted to the connecting rod 37, and it can fit tightly to achieve effective fixation. The locking frame 41 has a sliding groove on its outside. The sliding groove provides a path for the sliding of the toggle rod 42 to ensure that its movement is smooth and does not jam.

[0037] Working principle: By installing a running mechanism 3 and a locking mechanism 4 on the outside of elevator aluminum plate 1 and elevator aluminum plate 2, the splicing and fixing between the two aluminum plates is achieved. Four screws 312 are used to fix a fixing block 31 on the outside of elevator aluminum plate 1 to ensure the stability of the overall structure of the running mechanism 3. The fixing block 31 is connected to a connecting ring 32, which is movably connected to a connecting block 34 via a fixing bolt 33. The connecting block 34 is connected to a handle 35. When the operator pulls the handle 35, it will cause the connecting block 34 to rotate around the fixing bolt 33. The rotation of the connecting block 34 further drives the fixing bolt 36 to rotate. A connecting rod is fixedly connected to the top of the fixing bolt 36. 37. Therefore, the rotation of the fixing bolt 2 36 can adjust the length of the connecting rod 37. After adjusting the length of the connecting rod 37, it is fastened in the buckle plate 382 of the limiting component 38. The bottom of the fixing block 381 of the limiting component 38 is fixedly connected to the outside of the elevator aluminum plate 1. The buckle plate 382 plays the role of limiting and fixing the connecting rod 37, thereby fixing the elevator aluminum plate 1 and the elevator aluminum plate 2 together, realizing the splicing of the two aluminum plates. In order to prevent the handle 35 from popping open and causing the aluminum plate to separate from the aluminum plate, the fixing bolt 39 is inserted in the middle of the handle 35. The fixing bolt 39 is equipped with a connecting chain 310. The other end of the connecting chain 310 is fixedly connected to the connecting plate 311.

[0038] When the handle 35 springs open, the fixing bolt 39 and the connecting chain 310 will restrict it, preventing the handle 35 from rotating excessively and preventing the connecting rod 37 from coming off the buckle plate 382, ​​thus preventing the aluminum plate from separating from the aluminum plate. At the same time, it can also prevent the fixing bolt 39 from being lost. A locking mechanism 4 is installed at the center connection of the upper and lower aluminum plates. The bottom of the locking frame 41 is fixedly connected to the elevator aluminum plate 1. The lock cylinder 43 is movably connected inside the locking frame 41. The angle of the lock cylinder 43 can be adjusted by two levers 42. When the lock cylinder 43 rotates to the appropriate angle, it can lock the locking mechanism 4, further reinforcing the connection between the two aluminum plates from the center connection. This device uses the running mechanism 3 to splice and fix the elevator aluminum plate 1 and the elevator aluminum plate 2, and then reinforces the connection from the center position through the locking mechanism 4, realizing a stable splicing between the two aluminum plates.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
