Split installation type concrete foundation stone for props and installation method of the foundation stone

摘要

The present invention relates to a split installation type concrete foundation stone for a post and a method for installing the foundation stone. The base block is first installed in the excavated ground, and then the core block is combined and installed therein to facilitate construction and installation. In order to increase the overall construction efficiency by reducing heavy equipment and construction period because mortar input is unnecessary around the core block and the base block for fixing the block, the ground 2 is dug in the dug space part ( 3) the base block 10 to be seated on the horizontal bottom surface (4) in; The base block 10 is formed by a plurality of side walls 12 formed of concrete, each of which has an outer side 15 and an inner side 13, so that an installation space 19 is formed inside, and the A ring groove 16 for movement of the base block 10 is formed on the outer surface 15 , and is inserted into the installation space 19 of the base block 10 to be seated on the horizontal floor surface 4 . being a core block 30; The core block 30 is inserted into the installation space 19, the inner surface 13 of the base block 10 and the outer surface 32 facing with a spaced portion w of 3 to 10 cm The lower insert 31 is formed so as to be positioned, and a reduced step is formed on the upper portion of the lower insert 31 to be exposed to the ground 2, and a plurality of anchor bolts 37 for fixing the posts 9 ) is formed by the upper installation jaw 36 protruding, and the spaced portion w formed between the inner surface 13 of the base block 10 and the outer surface 32 of the core block 30 is in the space It is characterized in that it is formed by filling with mortar or sand so that the inner surface 13 of the base block 10 and the outer surface 32 of the core block 30 are positioned to be fixed to each other by filling.
