Abstract

The present invention relates to installation structure of a removal working rail for an FRP grating platform, comprising: a plurality of projections for rail installation on an upper side of a beam framework forming a platform; and a plurality of through holes wherein the projections for the rail installation are penetrated on a deck plate as the deck plate is installed in the upper side of the beam framework by using an FRP grating material. As a working rain is installed in an upper portion of the deck plate, a rail supporter connected with the projections for the rail installation of the beam framework is installed in the upper portion of the deck plate for a working load to be directly transferred to the beam framework. By directly transferring the working load to the beam framework, not to the deck plate, working is performed without damage to FRP grating during installing a machine and transferring a heavy product. By installing the working rail to be removable, the working rail installation is quickly performed during installing a machine and transferring a heavy product, and having an effect of freely passing as the working rail is dismantled on an ordinary day.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a FRP grating platform,

In the present invention, in installing a working rail on an upper part of a FRP grating used as a deck plate of a platform, a rail supporter for directly transmitting a work load transmitted through a working rail to a FRP grating without being transmitted to the FRP grating, The present invention relates to a removable work rail installation structure of an FRP grating platform that enables a worker to quickly install a work rail when installing a machine and transporting a heavy object so that work can be performed without damaging the FRP grating.

Generally, the platform of the offshore structure is equipped with a grating. The grating is provided as a moving path for supporting an object placed on the platform, or for moving the operator and the vehicle. The grating is supported and fixed to the supporter beam.

A method of installing the grating on the supporter beam is to form a hole in the supporter beam using a hilti, fix the bolt to the hole, and then connect the grating and the bolt with a fastener.

In general, the grating uses a steel grating, which has a strong strength but can be constructed at a low cost, has a workability advantage, but is heavy in weight, has a high corrosion resistance, The problem is very short, about 25 years.

Recently, FRP grating has been used as a substitute for steel grating. FRP grating is one third of weight of steel grating. It is easy to install because it is lighter than steel grating. It has no corrosion and has a useful life of at least 100 years, which is advantageous to produce various colors.

However, since the FRP grating is weak in structural strength compared with steel grating, there is a problem that it is difficult to carry and install heavy materials such as large-sized mechanical equipment.

Further, the rail supporter is formed with a " C "-shaped rail mounting portion with an upper opening, and a projection engaging portion is formed at a lower portion of the rail mounting portion to be fitted into the rail mounting projection of the beam frame.

In this case, the protrusion coupling portion is a tubular protrusion structure in which the rail mounting protrusion is fitted.

The deck plate of the offshore platform is formed of FRP grating material and a work rail detachably coupled to the beam frame is installed on the deck plate so that the working load is directly transmitted to the beam frame without being transmitted to the deck plate , It is possible to perform the work without damaging the FRP grating at the time of machine installation work and heavy material transportation.

In addition, the present invention provides a detachable mounting of working rails, which can quickly perform the installation work of the work rails during the machine installation work and the heavy material transportation work, and disassemble the work rails at ordinary times, .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an enlarged view of the main part of FIG. 1, and FIG. 3 is a side view of a detachable working rail installation structure of the FRP grating platform according to the present invention. And FIG. 4 is an assembled cross-sectional view showing a removable working rail installation structure of the FRP grating platform according to the present invention.

As shown in the figure, a beam frame 110 for forming a platform is installed. The beam frame 110 forms a frame of a marine platform as a frame of a structure using an H beam.

A plurality of rail mounting projections 111 are formed on the upper surface of the beam frame 110.

The rail mounting projections 111 may be equally spaced along the longitudinal direction of the beam frame 110. The rail mounting protrusion 111 may be a protrusion in the form of a circular column.

A deck plate 120 using FRP grating material is installed on the beam frame 110.

Here, the fiberglass reinforced plastic (FRP) refers to a glass fiber reinforced plastic in which glass fibers are intensively and continuously arranged and thoroughly mixed and combined with a resin (polyester or vinyl ester resin).

The deck plate 120 is formed with a plurality of through holes 121 through which the rail mounting projections 111 pass.

At this time, the height of the rail mounting protrusion 111 is formed to be higher than the depth of the through hole 121, that is, the thickness of the deck plate 120. Further, the inner diameter of the deck plate 120 may be formed to be larger than the diameter of the rail mounting protrusion 111 so that clearance is generated between the two.

The work rails 130 are installed on the deck plate 120. As shown in FIGS. 1 and 2, the work rail 130 provides a path for transporting the bogie 101, and can be used for transporting large machinery and materials.

The work rail 130 is installed on the deck plate 120 using the rail supporter 140. The rail supporter 140 is installed to be coupled to the beam frame 110 directly through the deck plate 120 So that the working load (the load due to the transportation of the machinery and the material) is directly transmitted to the beam frame 110 without being transmitted to the deck plate 120.

The rail supporter 140 is formed with a racket 141 having an upper opening and a rail mounting projection 111 of the beam frame 110 is fitted to a lower portion of the rail mounting portion 141, Thereby forming a projection-engaging portion 143 to be engaged.

At this time, the projection-engaging portion 143 may have a tubular projection structure in which the rail mounting projection 111 is fitted.

In other words, the protrusion coupling portion 143 may be a tubular protrusion structure inserted into the clearance space provided between the rail mounting protrusion 111 and the through hole 121 of the deck plate 120.

The rail mounting protrusion 111 may be formed in a tubular protrusion structure and the outer diameter of the protrusion fitting portion 143 may be smaller than the diameter of the rail mounting protrusion 111 so as to be axially coupled.

As described above, according to the present invention, a rail supporter, which allows a working load of a working rail provided on an upper part of a deck plate of a FRP grating material to be directly transferred to a beam frame, is detachably mounted on a rail deck plate, The work can be performed quickly without damaging the deck plate, and the work rail can be disassembled at a normal time, so that the work can be freely performed, thereby improving the space utilization.

For example, a person skilled in the art can change the material, size and the like of each constituent element depending on the application field or can combine or substitute the embodiments in a form not clearly disclosed in the embodiments of the present invention, Of the range. Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and that such modified embodiments are included in the technical idea described in the claims of the present invention.
