Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy template structures, and in particular to a reinforcement structure for the corner of aluminum alloy templates for chimneys. Background Technology

[0002] Chimneys are tall structures used in industrial and civil buildings to discharge flue gas. As high-altitude, thin-walled structures, chimneys present complex construction conditions, placing far higher demands on formwork systems than ordinary building formwork.

[0003] The corners are subjected to greater stress and have complex shapes, making them prone to deformation or damage, which affects the stability and safety of the overall formwork. Existing reinforcement methods usually employ a single reinforcement approach, such as increasing the corner thickness or adding independent reinforcement components (reinforcing ribs, diagonal braces, etc.), which have limited effectiveness and are structurally complex and inconvenient to construct.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1-4 As shown in the figure, the present invention provides a reinforcement structure for the corner of an aluminum alloy template for a chimney, comprising: an L-shaped right-angle back rib and an L-shaped support frame, both of which are formed by welding multiple steel pipes.

[0026] The L-shaped right-angle back rib includes a first steel pipe 1 and a second steel pipe 2. The two first steel pipes 1 are arranged in parallel, and the two second steel pipes 2 are also arranged in parallel. The first steel pipes 1 and the second steel pipes 2 are welded together. Several connecting steel pipes 5 are welded between the two first steel pipes 1 and between the two second steel pipes 2.

[0027] Correspondingly, the L-shaped support frame includes a third steel pipe 3 and a fourth steel pipe 4. The two third steel pipes 3 are arranged in parallel, and the two fourth steel pipes 4 are also arranged in parallel, and the third steel pipes 3 and the fourth steel pipes 4 are welded together. Several connecting steel pipes 5 are welded between the two third steel pipes 3 and between the two fourth steel pipes 4.

[0028] In this embodiment, the first steel pipe 1, the second steel pipe 2, the third steel pipe 3, the fourth steel pipe 4, and the connecting steel pipe 5 are all rectangular steel pipes of 30×70×2.5 mm. The length of the first steel pipe 1 is 1030 mm, the length of the second steel pipe 2 is 1100 mm, the length of the third steel pipe 3 is 530 mm, the length of the fourth steel pipe 4 is 600 mm, and the length of the connecting steel pipe is 60 mm. Standardization of steel pipe specifications can reduce manufacturing costs.

[0029] The reinforcement structure for the corner of the aluminum alloy template for the chimney also includes fasteners. The L-shaped right-angle back rib and the L-shaped support frame are fixed by the fasteners to form an integrated reinforcement system.

[0030] Specifically, the fasteners include a screw 6, an L-shaped right-angled back rib fitted onto one end of the screw 6, and an L-shaped support frame fitted onto the other end of the screw 6. A fixing plate 7 is fitted onto the screw 6, with fixing plates 7 fixed to both the outer side of the L-shaped right-angled back rib and the inner side of the L-shaped support frame. A washer 8 is also fitted onto the screw 6, and the washer 8 fits snugly against the fixing plate 7. A nut 9 is fitted onto the screw 6, and the nut 9 fits snugly against the washer 8.

[0031] In use, firstly, two first steel pipes 1, two second steel pipes 2, two third steel pipes 3, and two fourth steel pipes 4 are welded together using multiple connecting steel pipes 5. Then, the welded first and second steel pipe groups are welded together to form an L-shaped right-angle back rib. The third and fourth steel pipe groups are then welded together to form an L-shaped support frame. Next, the assembled L-shaped right-angle back rib and L-shaped support frame are placed at both ends of the screw 6, and then the fixing plates 7 and washers 8 are assembled in sequence. Finally, nuts 9 are used for locking. After installation, it can be used to reinforce the corners of aluminum alloy templates at the ends of chimneys, sharing the corner bending moment and shear force. The modular welded structure simplifies on-site installation, and the method of fastening with screws 6 and nuts 9 also improves overall rigidity and disassembly.

[0032] The reinforcement structure employed in this application makes the reinforcement of aluminum alloy formwork more convenient and faster. Compared to traditional methods that involve increasing corner thickness or adding independent reinforcement components, it improves work efficiency, reduces construction difficulty, and streamlines procedures. In traditional methods, increasing corner thickness requires design during the initial formwork manufacturing phase, making it difficult to adapt to specific conditions. Independent reinforcement components typically consist of reinforcing ribs (vertical ribs) and diagonal braces, which require grinding of the formwork or anchoring to other formwork components during construction, resulting in low construction and dismantling efficiency. Therefore, this application employs L-shaped right-angle back ribs and L-shaped support frames, fixed to the corners of the formwork with fasteners, reinforcing the corners while improving structural strength, reducing deformation, and simplifying and increasing construction efficiency.

[0033] It is understandable that the welding process in this application can employ double-sided full welding, making the fixation between steel pipes more secure.

[0034] Working principle: In use, firstly, two first steel pipes 1, two second steel pipes 2, two third steel pipes 3, and two fourth steel pipes 4 are welded together through multiple connecting steel pipes 5. Then, the welded first and second steel pipe groups are welded together to form an L-shaped right-angle back rib. The third and fourth steel pipe groups are welded together to form an L-shaped support frame. Next, the assembled L-shaped right-angle back rib and L-shaped support frame are placed at both ends of the screw 6. Then, the fixing plate 7 and the washer 8 are assembled in sequence. Finally, the nut 9 is used to lock it.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
