Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a foundation structure for constructing pillars such as poles for lighting lamps and poles for disaster prevention radio equipment.

[Conventional technology]

Conventional pillar foundations such as poles for lighting lamps are concrete foundations with a pillar hole formed by placing concrete into a predetermined formwork in the foundation hole, and the lower end of the pillar was inserted into the pillar hole. Later, a building pillar is constructed by filling the gap between the inner surface of the pillar hole and the outer surface of the pillar with mortar or the like.

[Problems to be solved by the device]

Since this conventional concrete foundation for building columns requires a concrete curing period of several days, building column work and backfilling around the foundation and leveling can only be performed after this, so the construction period is long, There is a problem that the cost is high.

Therefore, the present invention aims to enable the work from digging the foundation, building pillars, backfilling, and leveling to be performed all at once.

[Means for Solving the Problems]

According to the present invention, the above object is to stack a plurality of tubular concrete blocks each having a horizontally extending connecting screw hole so that the connecting screw holes correspond to the upper and lower sides and to connect the vertically extending connecting members to each other. It consists of a stack of tubular concrete blocks that are joined by fixing them through fastening bolts that screw into holes, and the top concrete block is screwed into a horizontal screw hole provided on the inner wall of the concrete block. And a foundation structure for a building column comprising a plurality of column support bolts extending toward the center of the concrete block.

[Action]

The foundation structure of the present invention is generally formed by sequentially stacking a plurality of concrete blocks in a dug foundation hole portion and connecting them to each other through fastening bolts and connecting members. Then, after inserting the lower end of the pillar to be built into the concrete block stacked joint, pull out the pillar support bolt toward the center and bring the head into contact with the pillar so that the pillar extends vertically in the center. The work is completed by a series of work in which concrete or mortar is poured into the stacked block of concrete blocks to carry out the building pillars, and then the surroundings of the foundation are backfilled to level the ground.

〔Example〕

The substructure of the present invention is, for example, as shown in the drawings, two rectangular tubular concrete blocks 11 in which inserts 12 with screw holes for forming screw holes for connection are embedded at four inner corners, and an inner concrete block 11 Embedding a threaded insert 14 that forms a threaded hole for connection at the four corners and embed another threaded insert 15 in the center of each side, and screw the pillar support bolt 16 into the threaded hole of the insert 15. 1
Put each square concrete block 13 in the foundation hole
It can be formed by stacking from the front two on the connection angle member 17 and the connection angle member 17 via the fastening bolts 18.

In the foundation structure thus formed, the lower end portion of the pillar 20 to be built thereafter is inserted into the inside, and four pillar support bolts 16
After supporting the central part by extending vertically by
The building pillar is made by filling concrete inside,
After this, the entire area will be completed by backfilling the foundation and leveling.

[Effect of device]

As is clear from the above, according to the foundation structure of the present invention, since it is not necessary to have concrete curing, it is possible to perform the work from digging the foundation to backfilling the building columns and foundations, and leveling all at once. .
