[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for a reinforcing rib of a column and a rib cover.

[0002]

2. Description of the Related Art Conventionally, props such as protective fences, lightings, and sign posts are fixed to steel and concrete floors with anchor bolts. In order to reinforce the welding strength of the column and the base plate against the bending that acts, a reinforcing rib material is generally provided.

However, this reinforcing rib material impairs the external appearance, there is a risk of the tires directly hitting the ribs at the time of a vehicle collision, the tires burst, and the traveling of the collision vehicle is hindered. It has the drawback of being severely damaged and falling.

Further, the corrosion of the anchor bolt is remarkable,
Conventionally, only the anchor bolt was covered with a cap.

[0005]

[Problems to be solved by the device]
It is an object of the present invention to provide a reinforcing rib cover for a column that solves the above-mentioned drawbacks, improves the appearance, allows the collision vehicle to move smoothly, and helps prevent corrosion of the anchor bolt.

[0006]

Therefore, according to the present invention, an upper opening having a size enclosing a column is formed on an upper surface, and a lower opening having a size enclosing a bottom of a reinforcing rib is formed on a lower surface. Part or all of the cover is provided with a cover main body formed on inclined surfaces along the respective inclinations of the reinforcing ribs of the supporting column, a hole is formed in one side surface of the cover main body, and the reinforcing rib of the supporting column is formed in advance in the hole. The projecting end of the hook that is locked to the locked piece is fixed to the end with a tightening fixture such as a nut.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The optimum construction of the present invention will be described with reference to FIGS. 1, 2, 5, and 6.
An upper opening a of a size enclosing the bottom of the reinforcing rib Y is formed on the lower surface of the reinforcing rib Y. The cover main body 1 is formed on the inclined surface of the cover main body 1, and the elongated hole 2 is formed in one side surface of the cover main body 1. The locked piece formed in advance in the reinforcing rib Y of the column X in the elongated hole 2 The end of the hook 3 locked to Z is projected, and a fastening fixture 4 such as a nut is attached to the end.
It is a fixing structure of a reinforcing rib and a rib cover in a column, which is characterized by being tightened and fixed by.

Further, another embodiment of the present invention will be described with reference to FIGS. 3 and 4. An upper opening a having a size enclosing the column X is formed on the upper surface, and a bottom portion of the reinforcing rib Y is formed on the lower surface. A lower opening portion b having a size enclosing the side wall, a part or all of the side surface is formed as an inclined surface along each inclination of the reinforcing rib Y of the support column X, and one of the four circumferences is provided independently. U-shaped cover 1 in which the cover 1a and the other three surfaces are integrally formed
b and the cover body 1 is provided, one or a plurality of holes 5 are formed in the flat cover 1a, and tap screws 7 are inserted from the holes 5 of the flat cover 1a into the tap holes 6 formed in the reinforcing rib Y of the column X in advance. It comprises a fixing structure of a reinforcing rib and a rib cover in a column, which is characterized by being inserted and tightened and fixed.

The material of the cover body 1 is a steel plate,
It may be made of a plastic or rubber material, or may be formed of a plurality of layers of these materials.

Further, it is desirable that the locked piece and the tap hole formed on the column X be formed on the reinforcing rib located on the back side.

[0011]

The method of use of the present invention will be described. The cover body 1 is inserted into the support column X in advance, and the reinforcing ribs Y of the support column X are inserted.
Is fixed to a steel and concrete floor via a base plate, the reinforcing ribs Y are covered and the cover body 1 is fixed to the reinforcing ribs Y by fixing means.
In addition, the cover body 1 includes a flat cover 1a and a U-shaped cover 1b.
Those divided into can be used for already fixed columns or can be used for repairs.

[0012]

According to the present invention, since the reinforcing rib Y of the column X is covered with the cover body 1 according to the present invention, dust is not collected near the rib material. The appearance is further improved, and the rib material is not exposed, so the collision vehicle will slide smoothly in the event of an emergency.
Further, as a result of coating the anchor bolts fixed via the base plate, the anchor bolts also have an extremely beneficial effect such as being able to contribute to the prevention of corrosion at the same time.
