Description

Euroform fixture {FIXING UNIT FOR EURO FORM}

The disclosed subject matter relates to a fixture for fixing the position of the euroform connecting portion used for installing the formwork.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

Usually, when constructing a concrete structure such as a building or apartment, a form is first made, and the concrete is poured into the form and then hardened to make structures such as walls and columns in stages. Such formwork is made in various types and shapes according to the characteristics or scale of the building being constructed. Recently, it is common to manufacture formwork using standardized Euroform.

The Euroform used for manufacturing such a conventional formwork is composed of a rectangular frame, a plate provided on one side of the frame, and a plurality of reinforcing members arranged in the frame to support the plate, and a plurality of pin grooves at regular intervals on the frame and A tie groove is formed.

The formwork is manufactured using a number of these Euroforms, so it is common to use pins and ties to fix the part where Euroform and Euroform are connected so that they do not flow when concrete is poured.

However, since the pin and the tie fix the side of the sheet material on which the Euroform and the Euroform are interviewed to each other, there is a disadvantage in that the portion where the edges of the Euroform meet cannot be completely fixed. In other words, when pressure is applied by the poured concrete, the Euroform and the corner where the Euroform is connected may flow.

Due to this problem, separate fixtures are installed at the corners where Euroform and Euroform meet, but there is no fixture that fixes the parts where the four corners meet. The disadvantage was that it took a long time.
