Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a steel column reinforced with stainless steel square columns.

(b) Conventional technology and problems to be solved by the present invention Conventionally, steel has been generally used for road sign posts and fire hydrant posts used in road safety protection facilities, etc., so they are susceptible to corrosion. Since it cannot withstand long-term use, paint is applied to the parts buried underground or the parts slightly exposed from the ground, but the disadvantage is that it corrodes very easily and requires a lot of effort and expense to replace. It was hot.

However, the exterior was simple and had no aesthetic sense, so it had the disadvantage of detracting from the city's beauty.

(c) Means for solving the problems In view of the above-mentioned problems, the present invention is an attempt to provide a steel support with a beautiful appearance and to make it robust.

That is, a reinforcing frame is protruded from the inside of the upper end, the outer periphery of the upper part of the protruding part is curved in an arc shape, and a steel support is fitted in the center of a stainless steel prismatic column fitted with a rim having a prismatic root. , whose roots protrude from the stainless steel rectangular column, and concrete or urethane resin is filled between the column and the reinforcing frame, as well as between the column and the stainless steel column.

(d) Embodiment and operation An example of the implementation of the present invention will be explained below with reference to the drawings.

In the figure, 1 is a stainless steel square column, and 2 is a reinforcing frame that has a hole 4 for inserting a steel column 3 on the inside of the upper end of the square column 1 and projects from the upper end of the square column 1.

Reference numeral 5 denotes a flange edge having a hole 6 for inserting the support post 3 on the upper surface, the outer periphery of the upper part being curved into an arc shape, and the root part being formed into a prismatic shape.

In 7, a steel column 3 is fitted into the center of the stainless steel column 1, its root protrudes downward from the stainless steel column 1, and concrete or urethane is placed between it and the reinforcing frame 2 and between the column and the stainless steel column. A curved mirror support consisting of a stainless steel square pillar 1 filled with resin and a steel support.

8 is a foundation concrete, in which the roots of the steel columns 3 and the roots of the stainless steel square columns 1 are buried.

Reference numeral 9 denotes a mirror mounting bracket attached to the top of the pillar 7 of the curved mirror.

Reference numeral 10 denotes a mirror angle adjustment fitting attached to the upper part of the mounting fitting 9.

Reference numeral 11 denotes a horizontal diamond-shaped mirror with rounded corners supported at the tips of the mirror mounting bracket 9 and the mirror angle adjustment bracket 10, and an eave 12 is attached to its upper edge.

Since the present invention is constructed as described above, when a steel support is to be installed, the reinforcing frame 2 protruding from the inside of the upper end of the stainless steel pillar 1 must be installed in advance.
The collar edge 5 and the stainless steel square column 1 fitted into the protrusion of
and the abutment surfaces of the stainless steel column 1 are welded together, and the column 3 is fitted into the center of the column, with the root of the column protruding downward from the lower end of the stainless steel column 1.
In addition, concrete or urethane resin is filled between the pillar 3 and the reinforcing frame 2 to form a stainless steel square pillar 1.
This is to be buried in the foundation concrete together with the roots of the concrete.

The contact surfaces between the reinforcing frame 2 and the flange 5 and the pillar 3 are welded in advance when the pillar is fitted to the stainless steel square pillar.

In addition, in the above embodiment, the model diamond-shaped mirror 11 with rounded corners is used, so the material cost can be reduced compared to the conventional circular mirror, and it harmonizes with the stainless steel prism 1. However, it also contributes to traffic safety because it can arouse the public's attention.

(e) Effects of the invention This invention has a reinforcing frame protruding from the inside of the upper end of a stainless steel prism, and a flange whose upper outer periphery is curved in an arc shape and whose root is prismatic is fitted into this protrusion. The support is fitted onto the stainless steel square pillar, the lower end of which projects downward from the stainless steel square pillar, and concrete or urethane resin is filled between the stainless steel square pillar and the support and between the reinforcing frame and the support before the foundation is built. Since the lower part of the stainless steel square pillar and the lower protruding part of the pillar are buried in concrete, the roots of the pillars, which are most prone to corrosion, can demonstrate the original performance of stainless steel and remain unaffected by wind, snow, and rainwater for a long time. Since it can be used, maintenance costs for the pillars can be significantly reduced, and the upper edge of the stainless steel square pillar is fitted with a rim with an arcuate upper circumference and a prismatic base. It has various characteristics such as being able to enhance the beauty of the city even when used as a support for a curved mirror.
