Description

  TECHNICAL FIELD The present invention relates to a steel formwork level difference processing structure capable of constructing a foundation using steel molds having different heights when connecting and constructing foundations having different finishing levels at the top.

  When constructing the foundation of a small-scale building such as a house, a steel formwork is generally used as the formwork of the foundation rising portion. The construction method of this steel formwork will be briefly explained. First, the steel formwork is opened at a predetermined interval on the steel formwork holder placed on the ground industry constructed by crushed stone, crushed stone and the like. The steel molds are assembled by aligning the top levels of the steel molds so as to face the two rows. Next, a ruler member (see, for example, Patent Document 1) is installed at the top end of the steel mold in order to ensure accuracy according to the steel mold. This ruler member is also used to hold the anchor bolt in a predetermined position. The ruler member is often made of a flat steel member in order to ensure a predetermined accuracy. This is because a steel member that has been subjected to bending, welding, or the like is likely to be crumpled with precision during production or storage.

By the way, there are various sizes of steel molds. However, as described above, since the ruler member installed at the top end of the steel mold is made of a flat member, it is necessary to align the top end level of the steel mold. For example, the perimeter foundation provided in the outer periphery of the building and the partition foundation provided in the indoor portion of the building differ in height by the height of the floor, and the top end level of the partition foundation is the top of the outer foundation. Although it is finished lower than the end level, the steel formwork used for construction is made of steel with the same height dimension even though the top end level of the partition foundation is lower at the connection part of the outer periphery foundation and the partition foundation. A formwork is used.
