As a result, it is possible to carry out work more conveniently and quickly, thereby pursuing simplicity of construction and providing a Euroform fixed band for cement columns that can significantly reduce labor costs by shortening air.

Euroform fixed band for cement columns according to the present invention, a pair of first square pipes having one side of the flat iron is attached to each end at the same time, the inclined surface is formed at the end of one of the flat iron and the length adjustment hole is formed on the other flat iron, and one side A length adjusting hole is inserted into the flat iron of the first square pipe and fitted into a pair of second square pipes having protruding brackets on the other side, and fixed to each of the length adjusting holes formed in the first and second square pipes. A binding pin, a connecting bolt which is assembled to the shaft so as to be rotatable within the inclined surface of the first square pipe, and which is fitted into the protruding bracket of the second square pipe, and a tightening nut which is fastened through a washer to the connecting bolt. The pair of first and second square pipes are fixed to each other by a binding pin inserted into the length adjusting hole in each diagonal direction. At the same time, the fastening nut is fastened to the connecting bolts inserted into the protruding brackets of the second square pipes.

In addition, the length adjusting hole formed in the second square pipe is characterized by consisting of an elliptical shape inclined in the 45 ° direction.

In addition, the protruding bracket is divided into two by the notch and at the same time the V-shaped groove is formed on the upper surface, the lower surface of the corresponding washer is characterized in that the triangular projection is formed to be engaged with each other.

According to the cement-formed euro-foam fixing band of the present invention as described above, it is possible to fix the euro-foam to be used in the case of constructing the cement column of the building more conveniently and quickly to perform more efficient work.

In addition, since it does not use a separate tie bolt, it is possible to shorten the air by simple construction, as well as to reduce labor costs, durability and lower the product price.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
