DETAILED DESCRIPTION

[0027] The application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0028] Reference Figures 1-5 As shown in the figure, a flexible template structure includes a flexible template belt 1, a flexible inner lining plate 2, a stiffening rib 3, a reinforcing crossbeam 4, a tie rod assembly 5, and a fastening ring assembly 6.

[0029] The flexible template belt 1 is a belt-shaped whole formed by splicing a plurality of unit bodies 11 together. Since the two adjacent unit bodies 11 can be deformed to a certain extent, the flexible template belt 1 can form a linear template belt 12, a circular ring template belt 13, or an S-shaped template belt 14, thereby meeting different requirements of the construction of the enclosure.

[0030] The unit body 11 is a vertical bar structure, and the profile of the unit body 11 is U-shaped, specifically including an outer arc surface 111, an inner flat surface 112, and a side flat surface between the outer arc surface 111 and the inner flat surface 112. The outer arc surface 111 is in contact with the reinforcing support assembly on the outer side, and the reinforcing support assembly provides the force for the enclosure of the unit body 11. The inner flat surface 112 is a flat surface directly in contact with the concrete of the enclosure or a flat surface for supporting the flexible inner lining plate 2.

[0031] The side flat surface on one side of the unit body 11 is provided with a side notch 113, and the side flat surface on the other side of the unit body 11 is provided with an integral side protrusion 114. The side notch 113 and the side protrusion 114 are circular or elliptical and matched with each other. The side protrusion 114 of one unit body 11 is clamped in the side notch 113 of the adjacent unit body 11, thereby achieving the splicing of the two adjacent unit bodies 11.

[0032] The side protrusion 114 is rotationally matched in the side notch 113 with the length direction of the unit body 11 as the axis. The other side of the unit body 11 is integrally connected with the side protrusion 114 through a side extension section 115. The side extension section 115 provides space for the rotation of the side protrusion 114, and ensures that the rotation angle of the side protrusion 114 in the side notch 113 is 0-120 degrees. The rotation of the side protrusion 114 is used to realize the transformation of various shapes of the entire flexible template belt 1.

[0033] The flexible formwork belt 1 can be used as a direct enclosure support component, but in most cases a flexible inner lining plate 2 needs to be added inside the flexible formwork belt 1. The flexible inner lining plate 2 has the same shape as the flexible formwork belt 1, which is also linear, circular or S-shaped. The inner contour surface (i.e. the inner plane 112) of the flexible formwork belt 1 is attached to support the flexible inner lining plate 2, providing inward support force for the flexible inner lining plate 2.

[0034] The flexible inner lining plate 2 is provided with vertical buckle 21, which is buckled into the joint between the adjacent two unit bodies 11 (at the side extension section 115), so that the flexible formwork belt 1 and the flexible inner lining plate 2 are limited and positioned accurately, avoiding slipping.

[0035] For the enclosure requirements of rectangular pouring space, the flexible formwork belt 1 is reinforced and supported by the reinforcing ribs 3, reinforcing beams 4 and pull rod assemblies 5. At this time, the flexible formwork belt 1 is linear. The reinforcing ribs 3 are vertically arranged, and the pull rod assemblies 5 are connected between the opposite reinforcing ribs 3, which are pulled at the upper part of the reinforcing ribs 3 to provide support force by pulling.

[0036] The upper end of the reinforcing rib 3 is provided with a seam hook 31, which is hung on the joint (side extension section 115) between the adjacent two unit bodies 11, realizing the placement of the reinforcing rib 3. The seam hook 31 is provided with a pull hole 32 connected with the pull rod assembly 5, realizing the pulling action of the pull rod assembly 5, which is preferably an adjustable pull rod.

[0037] The reinforcing rib 3 is provided with a plurality of beam holes 33 for the reinforcing beams 4. The reinforcing beams 4 are supported on the outside of the flexible formwork belt 1 by the reinforcing ribs 3, which provide support for the reinforcing beams 4. The reinforcing beams 4 are used to support the unit bodies 11 (outer arc surface 111) of the flexible formwork belt 1, ensuring the stability of the whole flexible formwork belt 1.

[0038] For the enclosure requirements of circular pouring space, the flexible formwork belt 1 is reinforced and supported by the fastening ring assembly 6, which is circular at this time. The fastening ring assembly 6 is also annular and is arranged outside the flexible formwork belt 1. One end of the fastening ring assembly 6 is provided with a threaded section 61, and the other end is welded with an end ring 62. The threaded section 61 passes through the end ring 62 and is connected with a nut, which is tightened to tighten the flexible formwork belt 1 by the fastening ring assembly 6.

[0039] The flexible formwork structure is easy to assemble and is mainly used for the formwork support of arc-shaped components. It can be used for column and arc-shaped component formwork, and even through customization and parameterized modeling, it can realize the formwork installation and reinforcement of various special-shaped components, while ensuring the accuracy of the components.

[0040] The foregoing basic examples and their further alternative examples of the present invention can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present invention. In the present invention, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
