Description

Technical Field

[0001] This utility model relates to the field of wind power technology, and in particular to a circular steel template that is easy to disassemble. Background Technology

[0002] In the construction of hybrid tower wind turbine foundations, the cavity is typically designed as a circular structure, with the inner formwork composed of multiple arc-shaped steel formwork panels. Because the outer arc length of the circular formwork is greater than the inner arc length, traditional methods prevent horizontal demolding; instead, a crane is used to lift the formwork upwards for removal, typically by 2-4 meters. However, after the concrete is poured, the expansion effect compresses the formwork, increasing friction and demolding difficulty during vertical removal, thus reducing construction efficiency. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a circular steel formwork that is easy to disassemble. By optimizing the formwork structure, it reduces the difficulty of demolding and improves construction efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A circular steel formwork that is easy to disassemble is composed of multiple arc-shaped steel formwork panels. The multiple arc-shaped steel formwork panels are divided into initial dismantling formwork, temporary formwork and standard formwork. A temporary formwork panel is spliced ​​on each side of the initial dismantling formwork panel, and several standard formwork panels are spliced ​​on the other side of the temporary formwork panel to splice the remaining inner formwork.

[0006] The two sides of the first dismantling template form a certain angle with the outer arc surface, and the angle is greater than 90°.

[0007] The inner arc length of the first dismantling template is greater than or equal to the outer arc length.

[0008] One side of the adjacent template is perpendicular to the arc surface, and the other side forms a certain angle with the outer arc surface, the angle being less than 90°.

[0009] Both sides of the standard template are perpendicular to the curved surface.

[0010] The included angle between the two sides of the first dismantling template and the outer arc surface is 100°.

[0011] The included angle between the collar side of the adjacent template and the outer arc surface is 80°.

[0012] The initial dismantling template, temporary template, and standard template are all made of Q355B steel plate with a thickness of 3mm.

[0013] The beneficial effects of this utility model are: the angle of the first demolding template is designed so that it can be easily demolded in the horizontal direction, and then the adjacent template is removed. The friction of the removal is significantly reduced, making it easy to disassemble. This effectively reduces the difficulty of demolding the template, shortens the construction time, and reduces the frequency of use of hoisting machinery, thus saving construction costs.

[0020] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] A circular steel formwork that is easy to disassemble is composed of multiple arc-shaped steel formwork 1s spliced ​​together. The multiple arc-shaped steel formwork 1s are divided into a first dismantling formwork 11, a temporary formwork 12 and a standard formwork 13. A temporary formwork 12 is spliced ​​on each side of the first dismantling formwork 11, and several standard formwork 13s are spliced ​​on the other side of the temporary formwork 12 to splice the remaining inner formwork.

[0023] The two sides of the first dismantling template 11 form a certain angle with the outer arc surface, and the angle is greater than 90°.

[0024] The inner arc length of the first dismantling template 11 is greater than or equal to the outer arc length.

[0025] One side of the adjacent template 12 is perpendicular to the arc surface, and the other side forms a certain angle with the outer arc surface, the angle being less than 90°.

[0026] The standard template 13 has two sides perpendicular to the arc surface and is mainly used for splicing integral circular steel templates.

[0027] The angle between the two sides of the first demolition template 11 and the outer arc surface is 100°. This angle design allows the first demolition template 11 to be easily disassembled in the horizontal direction after the concrete is poured. The first demolition template 11 can be removed by horizontal pushing and pulling or mechanical hoisting during the disassembly process, and no additional reinforcement support is required during the disassembly process.

[0028] The included angle between the collar side edge and the outer arc surface of the adjacent template 12 is 80°.

[0029] The first dismantling template 11, the temporary template 12 and the standard template 13 are all made of Q355B steel plate with a thickness of 3mm. The arc-shaped steel template 1 adopts a modular design, and each arc-shaped steel template 1 is a standardized component, which is convenient to assemble or disassemble according to construction needs.

[0030] After the concrete has been poured and reached its design strength, remove the formwork according to the following steps:

[0031] First, remove the initial demolding template 11 and utilize its angled features to allow for easy demolding in the horizontal direction;

[0032] Then remove the adjacent template 12. Since the first template 11 on one side has been demolded, the friction is significantly reduced, and it can be easily disassembled.

[0033] Finally, remove standard template 13 in sequence.

[0034] The above steps effectively reduce the difficulty of formwork removal, shorten construction time, and reduce the frequency of hoisting machinery use, thus saving construction costs.

[0035] For circular foundations with larger diameters, in order to speed up the construction progress, the number of initial dismantling formwork 11 and temporary formwork 12 can be increased and distributed in the same proportion. The initial dismantling formwork 11 should be set at symmetrical positions of the circular steel formwork to adapt to different construction needs.

[0036] Circular steel formwork is suitable for wind power foundation cavity structures of different diameters, and the number and splicing method of arc-shaped steel formwork can be adjusted according to the changes in cavity size to adapt to the construction requirements of foundations of different specifications.
