Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a support structure for columns, and can be used to support porch columns made of lightweight cellular concrete on the foundation of a concrete entrance porch or the like.

[Background technology]

Conventionally, many pillars have been used in buildings such as houses.

For example, as shown in FIG. 6, a porch 52 is formed at the entrance of a house 51 by pouring concrete or arranging blocks. A porch roof 53 extends above the porch 52 from the outer wall of the house 51, and a pair of porch pillars 54 forming a gate shape are used to support the tip of the porch roof 53.

Such porch pillars 54 usually have their upper ends connected to the porch roof 5.
3, and the porch 5 is positioned in accordance with this roof 53.
2, the anchor member 55 protruding from the bottom of the column is inserted into a sheath pipe (not shown) buried in the foundation of the pouch 52, and the grout filled in the sheath pipe A structure is adopted in which the anchor member 55 is fixed to the foundation of the pouch 52.

Normally, in order to attach the porch pillar 54 to the foundation, first, a sheath pipe buried in the foundation in advance is filled with grout, and the anchor member 55, which is provided protruding from the bottom of the porch pillar 54 in advance, is inserted into the sheath pipe. The porch pillars 54 are supported on the foundation. In this state, since there is a gap between the outer surface of the anchor member 55 and the inner surface of the sheath tube, the pouch column 54 is supported by the foundation in an inclined state. Therefore, in order to fix the porch columns 54 at right angles to the foundation, it is necessary to correct the inclination of the porch columns 54.

[Problem to be solved by the invention]

By the way, since a predetermined amount of grout is required to securely fix the anchor member 55 to the foundation, a predetermined space is provided between the outer surface of the anchor member 55 and the inner surface of the sheath tube. Therefore, the inclination of the porch pillars 54 is large, and combined with the heavy weight of the porch pillars 54, a large force is required to correct the porch pillars 54. Therefore, there has been a desire for a pillar support structure that allows easy correction of the tilted porch pillar 54 when the porch pillar 54 is attached to the foundation.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a column support structure that allows a tilted column to be easily corrected to be perpendicular to the foundation.

[Means to solve the problem]

The pillar support structure of the present invention is a structure in which a pillar is supported on a foundation by inserting an anchor member protruding from the bottom of the pillar into a sheath pipe buried in the foundation and filled with grout, the anchor member being inserted into a sheath pipe filled with grout. A spacer member larger than the width of the member and smaller than the width of the sheath tube is attached to the anchor member, and this spacer member is inserted into the sheath tube to support the pillar on the basis.

Here, a protrusion is formed on the surface of the anchor member,
The spacer member is formed into a hollow body having a hole in the outer wall through which the grout material in the sheath pipe flows into the spacer member, and the spacer member has at least one of a bottom and a top that engages with the protrusion. A locking portion may be formed to prevent the anchor member from coming off.

[Function] In the present invention having such a configuration, in order to support a column on a foundation, first, a sheath tube is buried in the foundation in advance, an anchor member is provided protruding from the bottom of the column, and a spacer member is attached to the anchor member. Attach. Thereafter, without filling the sheath pipe with grout material, or immediately after filling the grout material, the spacer member attached to the anchor member is inserted into the sheath pipe to support the column on the foundation. At this time, in order to attach the spacer member to the anchor member, the spacer member may be placed inside the sheath tube, and the anchor member may be inserted through the spacer member.

When the column is supported on the foundation, the gap between the spacer member and the source tube is small, and the inclination of the column with respect to the foundation is almost non-existent, or even if there is, it is small.

Here, if a hollow body having a hole in the outer wall and a locking part formed in the bottom etc. is used as the spacer member, the grout in the sheath pipe will flow into the spacer member through the hole. As a result, the amount of grout that can be filled into the sheath pipe can be increased to securely fix the column to the foundation.Furthermore, the protrusion formed on the surface of the anchor member is locked to the locking part of the spacer member. Therefore, the anchor member does not come off from the spacer member, and the column can be reliably supported to the foundation.
