Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy formwork technology, specifically to a pull-tab type aluminum alloy formwork reinforcement structure. Background Technology

[0002] As is well known, in the field of existing building formwork technology, aluminum alloy formwork has become the mainstream choice for cast-in-place concrete structure construction due to its lightweight, high strength and high turnover rate.

[0003] Traditional aluminum alloy formwork often uses bolts or pins for connection, which results in problems such as low installation efficiency and difficulty in disassembly. In particular, in complex structures such as shear walls, formwork misalignment and concrete bulging are prone to occur.

[0004] Specifically, in existing technologies, the tie-plate reinforcement scheme can improve the overall integrity of the formwork through lateral constraints, but the positioning accuracy of ordinary tie plates is insufficient, which easily leads to frequent grout leakage at the joints. In addition, traditional reinforcement components mostly rely on manual thread tightening, which is not only labor-intensive but also makes it difficult to ensure uniform stress at each connection point, affecting the accuracy of the formwork for repeated use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a pull-tab type aluminum alloy template reinforcement structure.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pull-tab type aluminum alloy template reinforcement structure, comprising an aluminum alloy plate, an auxiliary pull tab disposed between the aluminum alloy plates, the auxiliary pull tab being attached to the aluminum alloy plate, a first fixing hole disposed on the auxiliary pull tab, multiple sets of second fixing holes on the aluminum alloy sidewall, the first fixing hole and the second fixing hole being overlapped, a fixing rod disposed at the overlapped point, a fixing component for fixing the fixing rod disposed on the aluminum alloy plate, and an aluminum alloy tube disposed on the rear sidewall of the aluminum alloy plate.

[0009] To achieve rapid assembly and precise positioning, this utility model is improved as follows: the fixing component includes a fixing box, a limiting rod, a locking rod, and an assist shaft. The fixing box is located inside the aluminum alloy plate, the limiting rod passes through the fixing box, the locking rod is on the limiting rod and threadedly connected to it, the locking rod is fitted to and slidably connected to the inner side wall of the fixing box, the assist shaft is located at the upper end of the limiting rod, and auxiliary holes are provided at both ends of the fixing rod. The locking rod passes through the auxiliary holes and is slidably connected to them.

[0010] To further improve positioning, the present invention is improved by providing detachable limiting blocks at both ends of the fixing rod.

[0011] To provide an ergonomic operating handle, the present invention is improved by providing a turning block at the upper end of the assist shaft.

[0012] In order to effectively disperse the lateral pressure of the concrete and suppress the deformation of the formwork, the present invention is improved by providing reinforcing ribs at the splicing points of the aluminum alloy plates, and the reinforcing ribs and the auxiliary tie plates are arranged alternately.

[0013] To extend the service life of the components, the present invention includes the following improvement: the surface of the auxiliary pull tab is coated with an anti-corrosion layer.

[0014] To reduce cement residue on the template surface, the present invention includes the following improvement: the aluminum alloy plate surface is coated with a photocatalytic self-cleaning coating.

[0015] To enhance the damping effect between the assist shaft and the limiting rod and prevent accidental loosening caused by construction vibration, this utility model is improved by providing a friction plate between the assist shaft and the limiting rod.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a pull-tab type aluminum alloy template reinforcement structure, which has the following beneficial effects:

[0018] This pull-tab type aluminum alloy formwork reinforcement structure is equipped with auxiliary pull tabs and aluminum alloy plates to form a precise positioning system, ensuring the accuracy of formwork splicing. The design of the fixing rod passing through the overlapping hole creates a rigid connection node, effectively preventing the formwork from shifting and deforming during the concrete pouring process.

[0019] The aluminum alloy tube backing and auxiliary tie plates form a double support structure at the front and rear, which evenly distributes the lateral pressure of the concrete and avoids the bulging of the formwork caused by local stress concentration.

[0020] Equipped with a fixing component, the fixing box integrates a threaded linkage structure of a limit rod and a locking rod to ensure uniform force at each connection point. The turning block at the top of the assist shaft, in conjunction with the damping control of the friction plate, enables labor-saving operation. A single worker can easily complete the locking operation, simplifying the installation process and reducing reliance on tools. Attached Figure Description

[0029] Please see Figure 1-4 A pull-tab type aluminum alloy template reinforcement structure includes an aluminum alloy plate 1, with auxiliary pull tabs 7 arranged between the aluminum alloy plates 1. The auxiliary pull tabs 7 are attached to the aluminum alloy plates 1. The auxiliary pull tabs 7 are provided with a first fixing hole 12. The aluminum alloy sidewall has multiple sets of second fixing holes 13. The first fixing hole 12 and the second fixing hole 13 can overlap. A fixing rod 4 is provided at the overlapping point. A fixing component for fixing the fixing rod 4 is provided on the aluminum alloy plate 1. An aluminum alloy tube 11 is provided on the rear sidewall of the aluminum alloy plate 1. Removable limiting blocks 5 are provided at both ends of the fixing rod 4.

[0030] During use, the construction personnel first tightly attach the two aluminum alloy plates 1 according to the design position, ensuring that the plate surfaces are flat and aligned. At this time, the second fixing holes 13 on the side wall of the aluminum alloy plate 1 are symmetrically distributed. Then, the auxiliary pull tab 7 is inserted into the joint between the two plates. After it is in place, the first fixing hole 12 on the pull tab is rotated and finely adjusted to make it completely coincide with the second fixing hole 13 of the aluminum alloy plate 1, forming a through channel. The operator selects the fixing rod 4 and pushes it smoothly into the coinciding hole group. At this time, the auxiliary hole 8 on the fixing rod 4 is aligned with the locking mechanism axis of the fixing component. The operator uses the fixing component to fix and limit the fixing rod 4. Finally, the limiting block 5 passes through both ends of the fixing rod 4 for further fixation.

[0031] In practical use, rapid assembly and precise positioning are required. To meet these requirements, in this embodiment, the fixing assembly includes a fixing box 2, a limiting rod 9, a locking rod 6, and an assist shaft. The fixing box 2 is located inside the aluminum alloy plate 1. The limiting rod 9 passes through the fixing box 2. The locking rod 6 is on the limiting rod 9 and threadedly connected to it. The locking rod 6 is fitted against and slidably connected to the inner wall of the fixing box 2. The assist shaft is located at the upper end of the limiting rod 9. Auxiliary holes 8 are provided at both ends of the fixing rod 4. The locking rod 6 passes through the auxiliary holes 8 and is slidably connected to them. A turning block 3 is provided at the upper end of the assist shaft. A friction plate 10 is provided between the assist shaft and the limiting rod 9.

[0032] The operator uses a torque wrench to rotate the hexagonal tightening block 3. The power steering shaft amplifies the rotational force applied to the tightening block 3 by the operator (similar to the power steering system of a car). The limit rod 9 rotates accordingly. Under the limit of the fixed box 2, the locking rod 6 descends with the rotation of the limit rod 9, passes through the auxiliary hole 8, and limits the fixed rod 4 to achieve mechanical interlocking. At this time, the friction plate 10 is in a pre-compressed state and fits against the limit rod 9. Its viscoelastic properties will generate hysteresis resistance. When the manual force is removed, the static friction torque is always greater than the residual torque of the system, achieving zero displacement maintenance.

[0033] In practical use, it is necessary to effectively disperse the lateral pressure of concrete and suppress the deformation of the formwork. In order to meet the above requirements, in this embodiment, the aluminum alloy plate 1 is provided with reinforcing ribs at the splice, and the reinforcing ribs and the auxiliary tie plate 7 are arranged alternately.

[0034] In actual use, it is necessary to extend the service life of components. In order to meet the above requirements, in this embodiment, the surface of the auxiliary pull tab 7 is coated with an anti-corrosion layer.

[0035] In practical use, it is necessary to reduce cement residue on the template surface, reduce cleaning costs, and maintain the smoothness of the concrete forming surface. In order to meet the above requirements, in this embodiment, the surface of the aluminum alloy plate 1 is coated with a photocatalytic self-cleaning coating.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
