Abstract

The present invention relates to a traffic facility steel pole facilitating connection of an attaching bar, and more specifically, to a novel technique which conveniently connects an attaching bar to a steel pole by insertion to simplify installation and greatly improve a support force of the attaching bar. A conventional traffic facility steel pole has a small contact area to decrease a support force of an attaching bar when a pair of insertion fixing plates for supporting the attaching bar are tightly fixed on an inner surface of an attaching bar fixing holder, and a deflection load is concentrated on a contact portion between the attaching bar and the insertion fixing plates to cause a problem of bending and weak structural strength. To resolve the problem, the present invention tightly fixes an insertion fixing cap of an attaching bar inserted and fixed in an attaching bar fixing holder installed on a steel pole on the entire area of the inner surface of the attaching bar fixing holder to extend a contact area.

Description

[Transportation facilities steel pole with easy connection to adherence stick]

The present invention relates to a novel concept that not only simplifies construction by connecting an attachment stand to a pontoon, but also greatly improves the supporting force of an attachment stand.

In general, it is preferable that the traffic facilities (signposts, streetlights, traffic lights, milestones, etc.) are installed at a predetermined height above the road so that the driver can easily see them. In addition, Traffic facilities The pontoon is composed of a pontoon, which is vertically erected at the top of a pontoon foundation embedded in one side of the road, and an attachment pier extending from the top of the pontoon to the road side.

In order to increase the bearing capacity of the connecting rod having a length of about 3 to 6 meters, the conventional barrel having a weight of 80 kg is connected to the rod by a flange coupling type .

As a representative prior art related to the above-mentioned transportation facilities, there has been proposed a patent application No. 1520644 entitled "

This prior art eliminates the necessity of components such as a conventional integral flange and a connecting flange for connecting a steel rod to a mounting base, thereby eliminating expensive laser processing and welding work. The cost is reduced remarkably, and there is no protruding portion protruding outwardly of the pillar, so that when the pillar is loaded on the vehicle, the occupied area is small, thereby increasing the amount of the pillar and reducing the transportation cost.

However, in the prior art, when the pair of insertion and fixing plates, which serve to support the attachment table, are tightly fixed to the inner surface of the attachment table and the fixing holder, the supporting surface of the attachment table is inevitably reduced, The deflection load concentrates on the contact portion of the contact portion, resulting in warpage and weak structural strength.

In addition, since the welding work for integrally mounting the pair of insertion and fixing plates in a state of being separated from the mounting base is required at two places, it is difficult and time-consuming to manufacture, and it is costly to process and equip the two insertion and fixing plates .

In order to solve the above-mentioned problems, the present invention provides a method of mounting a mounting cap on an attachment base fixedly mounted on an inner surface of an attachment base, Technology to make it happen.

In addition, the present invention is characterized in that a work path formed on the outer circumferential surface of the spindle and the bottom of the fixture holder fixture, and the worker's hand is inserted into the work path formed on the bottom surface of the insertion fixation cap and the attachment stand, And to make it possible to smoothly carry out the bolting work.

According to the present invention, the inserting / fixing cap coupled to one side of the mounting base is tightly fixed to the entire region of the inner surface of the mounting base and the fixing holder, thereby greatly enlarging the grounding area, thereby improving the supporting force of the mounting base, .

Also, the grounding area between the mounting block and the insertion fixing cap is enlarged to prevent the deflection load from concentrating on the contact portion between the mounting block and the insertion fixing cap, thereby increasing the structural strength and improving the durability.

In addition, since the welding operation between the mounting table and the insertion fixing cap is performed only at one place, the welding operation is very easy, the working range is short and the manufacturing time is shortened. Thereby reducing the cost required.
