Description

Tank pole {still pole for electric railway}

The present invention relates to a pontoon that is installed on the rail line of the electric railway to support the tram line for supplying electricity to the electric vehicle.

To explain this in more detail, the catenary can be formed into a door-shaped trust type, but divided into a holding bar, a corner connecting bar, and a beam (cross bar) so as to be disassembled and combined, and each connecting end forms a binding protrusion and a binding recess correspondingly. In order to allow easy and reliable coupling, the pontoon, that is, the support bar, the corner connecting bar, and the beam (cross bar) relates to the catenary pontoon formed by forming a cross-section thereof into a polygon including an oval or a quadrilateral.

Iron bars used in the prior art were used by assembling a mountain angle (ANGLE) or used H-shaped steel.

The iron rods made by assembling the angle angle had problems that the assembly was not easy and the assembly time was too long, resulting in poor workability, not only easy maintenance, but also high maintenance costs. There was a problem, because the complex assembling the angle does not give a good impression even aesthetics.

In case of using H-beam as a pontoon, the weight of H-beam itself is too heavy to handle, and the construction property is remarkably inferior, and the construction cost and maintenance cost are also a problem. Since it is not absorbed and extinguished, the vibration is severely distorted and easily deformed, as well as a problem that does not give a good image in appearance.

In order to solve such a problem, it is known to use a steel pipe column having a circular cross section as a pontoon, which will be described with reference to FIG. 1. The iron rod of the round steel pipe is connected to the beam (2) and the support bar (3) by the corner connecting bar (4) and connected to the buried bar (5) at the bottom of the support bar (3) and embedded in the concrete fixture (20) And binding plates 6 and 7 in which binding grooves 6-1 and 7-1 are drilled at both ends of the beam 2, the holding bar 3, and the corner connecting bar 4, respectively. Fixing by means of the binding plate (6) (7) and each of the beams (2) and the holding bar (3) and the outer surface of the corner connecting bar (4) is connected to each other by the plurality of support pieces (8) is fixed .

However, the iron rod made of a circular steel pipe constructed and used as described above has a completely circular cross section, but can be installed with a beautiful appearance, but has a very weak bearing force because the cross section is completely circular.

As shown in FIG. 1, when the iron column is installed, the beam 2 is subjected to a large load downward and the support bar 3 is loaded inward due to the load of the facilities installed in the beam 2. There was a problem in that the iron rod was formed in a circular cross section without considering the state of force. That is, since a strong force is applied to the support bar 3 to the inside, a phenomenon occurs that the support bar 3 made of circular steel pipe gradually bends outward, and the beam 2 has a strong load to the lower side. There was a problem that will be bent to the lower side.

In addition, at both ends of the beam 2, the support bar 3, and the corner connecting bar 4, only the binding plates 6 and 7 through which the binding holes 6-1 and 7-1 are fixed are fixed. When binding them to each other by a fixing means such as a bolt nut, even if the corner connecting bar 4 and the beam 2 are lifted using separate equipment, the binding holes 7-1 and 7-1 on both sides are There was a problem that it was not easy to fit, it was dangerous, and workability was very poor. Especially, since the binding plates 6 and 7 connecting the corner connecting bar 4 and the beam 2 were kept vertical, the beam ( 2) was not easy to combine, and there was a problem of weak cohesion and support.

The present invention is to provide an improved tank line iron column to solve the above problems.

The present invention allows the catenary to be divided into a beam (cross bar), a corner connecting bar and a holding bar, and a buried bar, but the binding ends of the beam (cross bar), the corner connecting bar, the holding bar, and the buried bar are connected to each other. The binding groove is formed to face each other so that the binding stone piece can be inserted into or separated from the binding groove, and the cross section of the beam (cross bar) and the corner connecting bar and the holding bar is formed into an elliptical or quadrangular cross section, in particular, the beam It is an object of the present invention to provide a catenary pontoon formed by inclining outwardly each binding plate connected to the edge connecting bar and the edge connecting bar.

Another object of the present invention is to form a binding stone piece and a binding groove facing each other at the connection end of the beam (cross bar), the corner connecting bar, the holding bar, and the buried bar so that the binding stone piece can be inserted into or separated from the binding groove. It is possible to easily install, and in particular to provide a chariot pontoon so that the binding stone piece and the binding groove is formed in an oval or polygon corresponding to each other to maintain the combined state by combining them.

Another object of the present invention is to form a cross section of the beam (cross bar) and the corner connecting bar, the holding bar and the buried bar into a polygon including an oval or a quadrilateral to strengthen the strength, in particular when formed in an oval When formed with a long polygon and is provided to the tram line to be able to further strengthen the strength by installing the long side facing outwards.
