[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Example 1

[0030] A slipform construction concrete formwork, such as Figure 1 As shown, it includes a steel formwork 1, a slipform formwork 2 and connecting parts, wherein the steel formwork 1 is connected to the slipform formwork 2, the slipform formwork 2 is arranged on the inner side of the steel formwork 1, and a plurality of connecting parts are arranged on the outer side of the steel formwork 1, the connecting parts include a galvanized steel plate 3 and a steel pipe 4, one side of the galvanized steel plate 3 is connected to the steel formwork 1, and the lower end of the galvanized steel plate 3 is connected to the steel pipe 4.

[0031] In this embodiment, the slipform formwork 2 uses a polytetrafluoroethylene plate. Polytetrafluoroethylene has the physical properties of high strength (high strength-to-weight ratio), low friction coefficient, and low water absorption. It is an ideal material for making the slipform formwork 2. By pasting a polytetrafluoroethylene plate (5mm-8mm) on the inside of the original steel formwork 1 of the slipform, and then fixing it to the edge of the formwork with a flat-head chamfered hexagon socket screw 6, the adhesion between the formwork and the concrete can be effectively reduced, thereby reducing the cracking caused by the adhesion of the concrete.

[0032] like Figure 2 As shown in the figure, the template provided in this embodiment comprises, from the outside to the inside, a 4mm steel template 1, epoxy resin glue 5, and a 5mm polytetrafluoroethylene sheet. The 4mm steel template 1 serves to strengthen the template rigidity, while the 5mm polytetrafluoroethylene sheet reduces friction and is adhered to the steel template 1 via epoxy resin glue 5.

[0033] like Figure 3 As shown, in some embodiments, the templates can be connected to each other by multiple M16 torsion shear type high-strength bolts 7 according to the area of ​​the object to be used, and the sizes of each template are consistent.

[0034] like Figure 4As shown, the template also includes a connecting piece, which is connected to the 34*4 seamless steel pipe 4 through a 5mm galvanized steel plate 3 with a groove on the outside of the steel template, thereby playing the role of fixing and supporting the template.

[0035] Of course, the above specific models and values ​​can be adjusted in other embodiments.

[0036] In some embodiments, the template can also be combined with a slipform casting machine. The template is set on the outer walls on both sides of the concrete, and the slipform casting machine can be used to achieve continuous slipform casting of concrete.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made by those skilled in the art that fall within the spirit and principles of the present invention and do not require creative effort shall be included within the scope of protection of the present invention.
