Formwork unit and method for constructing concrete structure

Abstract

Provided are; a formwork unit suitable for efficiently forming a concrete structure; and a construction method. This formwork unit, which is a formwork unit for pouring concrete, is provided with: atleast one embedded panel; and at least one fixture that has an end face for abutting the embedded panel, is screwed and fixed at the end face to the embedded panel, and can be connected to an assemblylocation side connection member. It is desirable for the faces installed facing the inside of a concrete filling partition among the faces of the embedded panels to include faces having improved adhesiveness.

Description

technical field [0001] The present invention relates to a formwork unit used when forming a concrete structure by pouring concrete, and a concrete structure construction method using the formwork unit. Background technique [0002] In the construction process of concrete poured concrete structures, the formwork used to distinguish the filling range of concrete raw materials is mostly assembled by assembling a plurality of plates that can be removed from the concrete structure after construction (hereinafter, also referred to as "demolition plates"). ”) to form. The technology related to such a formwork for concrete pouring is described in the following patent documents 1-3, for example. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 7-279410 [0006] Patent Document 2: Japanese Patent Laid-Open No. 2004-183466 [0007] Patent Document 3: Japanese Patent Laid-Open No. 2012-224990 [0008] For...

AI Technical Summary

Problems solved by technology

However, this method will lead to an increase in the work, time, and cost required for the construction of the concrete structure, so it is not preferable.

In addition, even after the concrete is hardened, especially the side walls such as walls, ceilings, and bottom surfaces of beams are easy to fall off, and there is a risk of collapse due to earthquakes, etc.
