A foundation structure for facilities is provided to reduce the removal time and improve the appearance of the building exterior. A foundation structure for facilities comprises: a first vertical member(10), a second vertical member(11), a third vertical member(12), and a fourth vertical member(13) of pipe shape having an upper female nut(21) and a lower female nut formed on the inside diameter center area with having a boundary; a support body(40) of quadrangle connected a plural number of space adjustment horizontal bar(30,31) by welding each other; a support bar(50) in which a tip end part of an upper part is made of a male screw(51) by bending a lower part, screwed on the lower female nut; a straight bolt(60) of stainless steel material screwed up on the upper female nut; and a stainless steel nut(70) connected with the straight bolt to have a top part of the straight bolt become exposed out.

Description

Facility foundation structure {Facilitate basis structure}

The present invention relates to a facility foundation structure to be used for the foundation work of various facilities, and more particularly, to install a facility by using it for the foundation work for installing street lamps in the street, the milestone construction for roadsides, the foundation work for installing bus stops in cities, etc. Before use, it is arranged to a certain size and is used to join with a nut by inserting the bolt into the through hole at the bottom of the facility.

In order to use the facility foundation structure, the earth and sand of the ground of the facility installation site is discharged, and then the facility foundation structure is put in the basement, and only the bolt part is exposed to the ground and used for finishing work with mortar.

In general, the facility foundation structure for installing the facility is used by fastening the nut to the bolt part after the foundation work of the ground. Generally, the upper part exposed to the ground is cut after bending to the standard dimension and then threading the upper part exposed to the ground. It is used for foundation work when constructing facilities such as bus stops, street lights, soundproof walls, etc., and it is conventionally made in one piece, and there is no problem in use.

This conventional facility foundation structure has no problem when installing and using the facility for the first time, but after a long time, rust on the exposed part of the ground is rusted, so the aesthetics are not good. have.

In order to solve the above problems, in recent years, the entire structure of facility foundations is made of stainless steel round rods. As construction costs rise, it is becoming a factor.

The present invention was developed to solve this problem, the part buried underground to install the structure is made of ordinary deformed steel bar and only the part exposed to the ground by using a stainless steel material that does not use the rust of the facility foundation structure To reduce the production cost, and after construction is to achieve the same effect as the conventional.

According to the present invention, the first vertical member, the second vertical member, the third vertical member, and the fourth vertical member are formed by forming an upper arm nut and a lower arm nut at the center portion of the inner diameter of the pipe shape cut into a predetermined length. In the support body, which is welded to the member by a plurality of upper and lower spacing rails, respectively, and joined in a rectangular shape, each lower arm nut is bent at the bottom and the upper end is screwed with a support made of a male screw, and the upper arm nut is made of stainless steel. It is intended to achieve the same effect as a product made of high-quality materials at low cost by screwing a flat bolt made of material and exposing the top of the flat bolt to the top of the upper female nut to form a structure by combining stainless nuts.

In the present invention, the parts buried underground have a low material cost, and when they are buried in the mortar used when buried underground, the use of deformed steel that does not rust reduces the cost and at the same time the parts exposed to the ground are not rusted stainless steel. By exposing the bolts of the material to prevent the rust from appearing, the aesthetics look beautiful, and the dismantling work can be done conveniently when dismantling the facility.

According to an embodiment of the present invention, the first vertical member 10 and the first vertical member 10 formed by forming an upper arm nut 21 and a lower arm nut 22 having a boundary portion 20 at a central portion of a pipe-shaped inner diameter cut to a predetermined length are provided. The support body 40 which combines the upper and lower space adjusting rails 30 and 31 to the two vertical member 11, the third vertical member 12, and the fourth vertical member 13 to form a quadrangular shape. In each lower arm nut 22, the lower end is bent and the upper end is screwed to the support 50 made of a male screw 51, the upper arm nut 21 is a stainless steel bolt (60) Screwed to and the upper part of the straight bolt 60 is exposed to the upper upper end of the nut nut 21 to combine the stainless nut 70 to the structure 100.

In the first vertical member 10, the second vertical member 11, the third vertical member 12, and the fourth vertical member 13, the boundary portion 20 is disposed at the center of the inner diameter of the support member 50. The male screw 51 and the flat head bolt 60 are respectively stopped at the same position when screwed to the lower arm nut 22 and the upper arm nut 21 for convenience of work and easy standardization. In order to be able to produce the same product all the time.

If you want to install in the installation place of the facility using the present invention as described above, and then cover the ground of the location to be installed, then the structure 100 of the present invention to the ground so that the support body 40 is buried underground And then put it in the part of the ground covered with mortar.

When the mortar is put into the covered ground as described above, the support body 40 is completely buried underground and at the same time works to expose only the portion of the straight bolt 60 to the ground.

After curing the mortar after the above operation, the stainless nut 70 is separated from the straight bolt 60, and then the lower part of the pillar of the facility, such as a street lamp, traffic sign, bus stop, etc. 60) and then combine the stainless nut (70) with a straight bolt (60) to complete the construction of the facility.
