DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a base pipe slidably fitted in a base pipe buried in the ground, or a support body fixed to the buried base pipe and erected on the ground.
Alternatively, the present invention relates to a pillar base structure for directly fixing and erection of a pillar body on a cast foundation, and a method of constructing the foundation structure.

[0002]

2. Description of the Related Art For example, a strut composed of a foundation pipe and a strut main body, wherein the strut body is fitted inside a foundation pipe buried in the ground and slidably retractable with respect to the foundation pipe, is a conventionally known strut. Things. This foundation pipe is formed of a pipe that is substantially longer than the main body of the strut and is placed in the excavated ground, and a certain range around the foundation pipe is surrounded by a wooden form material to form a formwork. It was constructed by pouring concrete into the formwork outside the foundation pipe, removing the formwork material after the foundation concrete had solidified, and backfilling the surroundings.

[0003] In addition, the construction of a pillar foundation in the case of fixing the pillar body to the buried foundation pipe and erecting it on the ground, or directly fixing the pillar body to the cast foundation, and erecting the same, is almost as described above.ゞ The same work has been done.

[0004]

The means for constructing these pillar foundations requires an operation of transporting a wooden form material to a work site and cutting it to a predetermined size. The assembling work is extremely troublesome and time-consuming, and the work of removing the form material after the solidification of the concrete is also complicated, and the waste of materials, labor, work time, and the like due to these can not be ignored.

According to a third aspect of the present invention, one end of a plate-shaped stay is fixed to the outer periphery of the underground portion of the pillar body along the axial direction along the one edge of the plate-shaped stay, and the other end of each stay is fixed. In addition to mounting the form plates, the adjacent edges of the form plates are joined to each other, and the inside of the form formed by the outer form plates at the lower part of the support body is hardened with concrete. It is a basic structure of a pillar that is a feature.

According to a fourth aspect of the present invention, the stay is fixed by inserting one end into a plurality of guide grooves formed on the outer periphery along the axial direction of the underground portion under the pillar body. 4. The strut according to claim 3, wherein one end edge is inserted into a plurality of guide grooves formed on an outer periphery of the band member which is surrounded and tightened around the embedded portion, and is fixed via the band member. Is the basic structure.

According to a fifth aspect of the present invention, there is provided the pillar base structure according to any one of the first to fourth aspects, wherein adjacent edges of the form plate are joined by a joint member.

According to a sixth aspect of the present invention, the number of the stays is three or four, and the form plate is attached to the other end of the stay and both end edges of the form plate are joined to form a triangular or four-sided stay.

A method of constructing a support pillar substructure, characterized in that one end edge is inserted and fixed via the band member.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION A strut applied to a strut substructure according to the present invention is such that a strut body is fitted inside a foundation pipe buried in the ground and hardened with concrete, and is slid up and down in the foundation pipe. It may be of a structure that can be retracted and retracted, or it may be one that only fixes the base part of the support body to the foundation pipe and only stands the support body on the ground, It is also possible to use a pillar that is directly fixed to concrete and erected on the ground by fixing the underground portion below the pillar body. Since the foundation pipe applied to the column only having the column main body standing on the ground may be short, the formwork to be set has a shallow depth.

The stay fixed to the underground portion of the foundation pipe or the pillar body of the foundation structure is inserted into a plurality of guide grooves formed on the outer circumference along the axial direction of the underground portion of the foundation pipe or the pillar body. In addition, the band member may be surrounded and tightened around the outer periphery of the foundation pipe or the underground buried portion of the lower part of the support body, and one end edge of the stay may be fixed to a plurality of guide grooves formed on the outer periphery of the band member. It may be inserted and fixed.

The band member may be a band member formed by combining the divided members, or may be a single band member that is not divided. Any band member that surrounds the outer circumference of the underground buried portion of the main body and tightens the main body may be used.

The band member, the stay, the form plate and the like for setting the base pipe of the base structure or the underground portion under the column main body may be made of any of metal and plastic. However, it is inexpensive, can be mass-produced, is lightweight and easy to transport and handle. It is preferable that the band member, the stay, the form plate, and the like be made of recycled waste plastic.

The number of guide grooves formed in the longitudinal direction of the outer circumference of the underground portion of the base pipe or the lower part of the support body may be plural as long as it is plural. There is also no particular limitation, and there is no particular limitation on the length or width of the stay attached to the guide groove.

The form plates attached to the stays may be connected to each other to form a flat plate that forms a rectangular frame as a whole in plan view. Alternatively, the form plates connected to each other are entirely circular in plan view. Alternatively, a curved form plate forming an oval or other frame may be used. However, for simple and advantageous construction, it is not preferable to form a mold having a complicated shape. The number of the guide grooves provided on the outside of the foundation pipe is three or four, and the guide grooves are fixed to these guide grooves. Each of the three or four stays is fitted with the central part of the same three or four plate-shaped form plates, and the corners formed at both edges of the form plate are preferably used as corner joints or the like. It is desirable to form a triangular or quadrangular formwork in plan view by joining with a joint member.

In the method for constructing a pillar base structure according to the present invention, the band member, the stay, the form plate, etc., which are set around the foundation pipe or the underground portion under the pillar body, are made of plastic. As described above, it is easy to handle and the concrete can be buried even after the concrete has been poured in, so that the man-hours and work time of the construction can be saved, and the construction cost can be reduced.

[0020]

According to the present invention, there is provided a pillar base structure, which comprises a base pipe for supporting a pillar body or an underground buried portion under a pillar body which is easily assembled in advance into the ground. Since a formwork plate is used, the production and assembly of the formwork can be performed easily and quickly.
By forming these materials into plastic moldings, they are lightweight and can be more advantageously transported and handled.

Further, the method for constructing a pillar base structure according to the present invention relates to a band member, a stay, a form plate and a joint used as needed around a foundation pipe or a buried portion under the pillar body underground. Since it is only necessary to sequentially connect the frame materials such as members and simply assemble them, it is possible to easily and quickly construct the basic structure without requiring the hands of a skilled person. In particular, a more advantageous construction can be achieved by using a plastic which is inexpensive and can be left even after embedding the form materials such as the band member, the stay, the form plate and the joint member.
