Detailed Implementation

[0033] The following non-limiting examples are used to illustrate the present invention.

[0034] Example 1

[0035] refer to Figures 1-4 As shown, a construction method for a flexible formwork includes the following steps.

[0036] Step 1: Assemble the flexible template strip 1. According to the needs of the enclosure, assemble the independent unit 11 into the whole flexible template strip 1.

[0037] Unit 11 is a vertical strip structure with a U-shaped outline. Specifically, it includes an outer arc surface 111, an inner plane 112, and a side plane between the outer arc surface 111 and the inner plane 112. The outer arc surface 111 is in contact with the outer reinforcement support component, which provides the unit 11 with the enclosure force. The inner plane 112 serves as a plane that directly contacts the enclosure concrete or supports the flexible inner lining plate 2.

[0038] A side slot 113 is provided on one side plane of unit body 11, and a side protrusion 114 is provided on the other side plane of unit body 11. The side slot 113 and the side protrusion 114 are mutually matching circles or ellipses. The side protrusion 114 of one unit body 11 is engaged in the side slot 113 of the adjacent unit body 11. The side protrusion 114 rotates and engages in the side slot 113 with the length direction of unit body 11 as the axis, so as to realize the splicing between two adjacent units body 11. Then, several units body 11 are spliced ​​together to form a strip-shaped integral flexible template strip 1.

[0039] The side protrusion 114 rotates within the side groove 113 about the length of the unit 11. The other side of the unit 11 is integrally connected to the side protrusion 114 via a side extension 115. The side extension 115 provides space for the rotation of the side protrusion 114, ensuring that the rotation angle of the side protrusion 114 within the side groove 113 is 0 degrees to 120 degrees. The rotation of the side protrusion 114 enables the entire flexible template strip 1 to achieve various shape transformations.

[0040] Step 2: Install flexible formwork strip 1 to form the pouring space.

[0041] The flexible formwork strip 1 is formed by splicing together several unit bodies 11 into a strip-shaped whole. Since a certain degree of rotational deformation can occur between two adjacent unit bodies 11, the flexible formwork strip 1 can form a straight formwork strip 12, a circular formwork strip 13 or an S-shaped formwork strip 14, which can meet different construction needs of the enclosure.

[0042] Depending on the needs of the enclosure, the flexible formwork strip 1 can be one or more of the following: straight formwork strip 12, circular formwork strip 13, or S-shaped formwork strip 14. It can be used for construction enclosure of rectangular pouring space, circular pouring space, or other irregular pouring space.

[0043] Step 3: Install flexible inner lining plate 2 on the inside of flexible template strip 1. Use flexible template strip 1 to provide support for flexible inner lining plate 2. The shape and outline of flexible inner lining plate 2 are consistent with flexible template strip 1, and are also straight, S-shaped or circular.

[0044] The flexible inner lining plate 2 is provided with an integrated buckle 21 on the outside. The buckle 21 is arranged vertically and is inserted into the joint formed between two adjacent unit bodies 11 (i.e., at the side extension section 115). Thus, the flexible template strip 1 and the flexible inner lining plate 2 are mutually locked and limited to ensure the accuracy of their positions and prevent them from slipping.

[0045] Step 4: Install reinforcement support components on the outside of the flexible formwork strip 1. Use the reinforcement support components to provide support for the flexible formwork strip 1, realize the overall formwork enclosure and support, and avoid bulging and displacement of the formwork during pouring.

[0046] The reinforcement support assembly includes reinforcing ribs 3, reinforcing beams 4, and tie rod assemblies 5. Several reinforcing ribs 3 are vertically and equidistantly arranged on the flexible template strip 1. Reinforcing beams 4 supporting the outside of the flexible template strip 1 are installed on the reinforcing ribs 3. Tie rod assemblies 5 are connected between opposite reinforcing ribs 3.

[0047] For the enclosure requirements of rectangular casting spaces (walls), the flexible formwork strip 1 is reinforced and supported by reinforcing ribs 3, reinforcing beams 4, and tie rod assemblies 5. At this time, the flexible formwork strip 1 is straight. The reinforcing ribs 3 are arranged vertically, and tie rod assemblies 5 are connected between opposite reinforcing ribs 3. The tie rod assemblies 5 are installed on the upper part of the reinforcing ribs 3 to provide support force through tension.

[0048] 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) formed between two adjacent unit bodies 11 to realize the placement of the reinforcing rib 3. The seam hook 31 is provided with a pull hole 32 for connecting the pull rod assembly 5 to realize the pull action of the pull rod assembly 5. The pull rod assembly 5 is preferably an adjustable pull rod.

[0049] The reinforcing rib 3 is provided with several beam holes 33 through which the reinforcing beam 4 passes. The reinforcing rib 3 is provided with a reinforcing beam 4 that supports the outside of the flexible template strip 1. The reinforcing rib 3 provides support for the reinforcing beam 4, and the reinforcing beam 4 supports the unit body 11 (outer arc surface 111) of the flexible template strip 1, so as to ensure the stability of the overall flexible template strip 1.

[0050] Step 5: Pour concrete into the flexible inner lining plate 2.

[0051] Example 2

[0052] refer to Figures 1-2 , Figures 5-6 As shown, a construction method for a flexible formwork includes the following steps.

[0053] Step 1: Assemble the flexible template strip 1. According to the needs of the enclosure, assemble the independent unit 11 into the whole flexible template strip 1.

[0054] Unit 11 is a vertical strip structure with a U-shaped outline. Specifically, it includes an outer arc surface 111, an inner plane 112, and a side plane between the outer arc surface 111 and the inner plane 112. The outer arc surface 111 is in contact with the outer reinforcement support component, which provides the unit 11 with the enclosure force. The inner plane 112 serves as a plane that directly contacts the enclosure concrete or supports the flexible inner lining plate 2.

[0055] A side slot 113 is provided on one side plane of unit body 11, and a side protrusion 114 is provided on the other side plane of unit body 11. The side slot 113 and the side protrusion 114 are mutually matching circles or ellipses. The side protrusion 114 of one unit body 11 is engaged in the side slot 113 of the adjacent unit body 11. The side protrusion 114 rotates and engages in the side slot 113 with the length direction of unit body 11 as the axis, so as to realize the splicing between two adjacent units body 11. Then, several units body 11 are spliced ​​together to form a strip-shaped integral flexible template strip 1.

[0056] The side protrusion 114 rotates within the side groove 113 about the length of the unit 11. The other side of the unit 11 is integrally connected to the side protrusion 114 via a side extension 115. The side extension 115 provides space for the rotation of the side protrusion 114, ensuring that the rotation angle of the side protrusion 114 within the side groove 113 is 0 degrees to 120 degrees. The rotation of the side protrusion 114 enables the entire flexible template strip 1 to achieve various shape transformations.

[0057] Step 2: Install flexible formwork strip 1 to form the pouring space.

[0058] The flexible formwork strip 1 is formed by splicing together several unit bodies 11 into a strip-shaped whole. Since a certain degree of rotational deformation can occur between two adjacent unit bodies 11, the flexible formwork strip 1 can form a straight formwork strip 12, a circular formwork strip 13 or an S-shaped formwork strip 14, which can meet different construction needs of the enclosure.

[0059] Depending on the needs of the enclosure, the flexible formwork strip 1 can be one or more of the following: straight formwork strip 12, circular formwork strip 13, or S-shaped formwork strip 14. It can be used for construction enclosure of rectangular pouring space, circular pouring space, or other irregular pouring space.

[0060] Step 3: Install flexible inner lining plate 2 on the inside of flexible template strip 1. Use flexible template strip 1 to provide support for flexible inner lining plate 2. The shape and outline of flexible inner lining plate 2 are consistent with flexible template strip 1, and are also straight, S-shaped or circular.

[0061] The flexible inner lining plate 2 is provided with an integrated buckle 21 on the outside. The buckle 21 is arranged vertically and is inserted into the joint formed between two adjacent unit bodies 11 (i.e., at the side extension section 115). Thus, the flexible template strip 1 and the flexible inner lining plate 2 are mutually locked and limited to ensure the accuracy of their positions and prevent them from slipping.

[0062] Step 4: Install reinforcing support components on the outside of the flexible formwork strip 1. These components provide support for the flexible formwork strip 1, achieving overall formwork enclosure and protection, preventing bulging and displacement of the formwork during pouring. The reinforcing support components include fastening ring components 6, which are clamped onto the outside of the flexible formwork strip 1.

[0063] For the enclosure requirements of circular casting spaces (cylinders), the flexible formwork strip 1 is reinforced and supported by the fastening ring assembly 6. In this case, the flexible formwork strip 1 is annular. The fastening ring assembly 6 is also annularly clamped on the outside of the flexible formwork strip 1. One end of the fastening ring assembly 6 is machined 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 to a nut. The fastening ring assembly 6 clamps the flexible formwork strip 1 by tightening the nut.

[0064] Step 5: Pour concrete into the flexible inner lining plate 2.

[0065] The above are just some examples of construction methods for flexible formwork, which can also be adapted to the construction of most curved components. The formwork itself has high rigidity, so construction does not require many reinforcing members, resulting in quick construction and good forming effect.

[0066] 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.

[0067] 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.
