The present application includes a system configured to simplify the application of plugs into holes created in concrete slabs during a termiticide treatment process. The system includes a flexible plug for insertion into the hole one or more times. A plug tip is coupled to a tool and selectively adjusted to a particular depth. A locating element is included to prevent the over protruding of the plug tip in the hole. The tool is used by the user to insert the plug tip into the hole wherein the depth is governed by the location of the locating element. The plug tips may be interchanged or adjusted in depth along with the locating element. Once the plug has been located properly, a patch is then applied to the remaining hole.

A method for manufacturing a concrete structure comprises an installation step of installing a formwork 30 for concrete placement, a placement step of performing concrete placement in a state where a curing sheet 10 is attached to an inner surface of the formwork 30, and a demolding step of removing the formwork 30 after placement of concrete C. A contact angle of a contact surface of the curing sheet 10 for use in the placement step with water is 50 degrees or more, wherein the contact surface faces the concrete. Thus, generation of bleeding water is suppressed.

Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

A sealing plug including an elastic body and a stem coaxially assembled to one another. The elastic body has a main body which is suitable for being expanded radially when pulling on the free end of the stem which emerges out of said elastic body. The elastic body also has a head attached to the main body, the head having a compressive strength less than that in the main body.

Formwork tube consisting of a first portion with a first conical end, and a second portion with a second conical end. The first portion and the second portion are coupled to each other, so that the tube can be completely extracted from the formwork after use. The first portion is extracted from one of the sides of the formwork while the second portion is extracted from the other side of the formwork. The formwork tube is suitable for housing therein a transverse tie rod.

Various implementations described herein are directed to a bracket of a formwork system. In one implementation, the bracket includes: a first member having a first plurality of openings; and a second member having a second plurality of openings. The first member and the second member are configured to: be perpendicular to each other, and provide lateral adjustment via the first plurality of openings and/or the second plurality of openings.

A plug for closing a hole in a concrete wall. The plug includes a main body and elastic retention means. The retention means includes at least one hook partially embedded in the main body and partially projecting from the main body, the at least one hook being configured for cooperating with the hole in the concrete wall for retaining the plug in the hole.
