TEZUKA JUNICHI / KITAKAMAE MASARU / HASEGAWA MOTONORI / HASHIMOTO TAKASHI

To provide a columnar foundation structure molding member that enhances the bondability between a slab floor and a column foundation and enables a slab floor forming step and a column foundation forming step to be efficiently performed, and a construction method of a building foundation using the same.SOLUTION: A columnar foundation structure molding member for forming a columnar foundation structure erected in a mat foundation main bar structure that constitutes a mat foundation of a detached building has a cylindrical covering member whose top and bottom form open surfaces, and a plurality of supports that support the covering member. The covering member is formed with a notch on one open surface side to engage the support. The support has a round bar-shaped column base bolt with a male screw formed on the peripheral surface over the entire length, and a support member in which an engaging portion to be inserted into the notch and a screwed portion having a female screw to be screwed with the column base bolt are integrally formed.SELECTED DRAWING: Figure 1
