Cable Tray Upper Cover {Cable Tray Upper Cover}

The present invention relates to a structure of an upper cover that covers the upper opening of a cable tray for receiving a cable bundle and guiding the cable safely to a destination, and more specifically, the left and right side rails having a cross-section having a 'c' shape and connecting the same. The cover structure is formed of a rung (Rung) to cover the upper portion of the cable tray for guiding the cable to the destination, coupled to the upper end of each of the side rails 11 are arranged in a symmetrical arrangement, respectively the inclined surface on both sides A pair of inclined panels 100 to form; And a central connection member 200 coupled to each end of the pair of inclined panels 100 at a central upper portion of the cable tray to integrally connect the pair of inclined panels 100. It is characterized by.

In general, cables of large and small diameters are routed along floors, walls, or ceilings to supply power or fluids to ships, plants, or other industrial facilities. They were wired with the support of the cable trays so as not to inconvenience them.

In other words, the cable tray is designed to secure the path in which a large amount of cables are arranged in factories, ships, and large buildings in advance, to reduce the space for laying cables and to reduce the time for laying cables, and to effectively manage the cables. After that, the cables are arranged in sequence along the path of the installed cable trays. The conventional cable trays have a rung 22 supporting the cable to be wired and side rails 11 vertically attached to both left and right sides of the rung 22. It is composed of, and suspended in a space such as the ceiling using an angle member (not shown).

After the installation of the existing cable tray is completed, the cable is wired into the inner space (inner space consisting of the rung 22 and the side rails 11 on both sides). In some cases, it may be left alone, but in order to protect the cable from external foreign matters (to prevent damage or contamination of the cable), a separate cover is installed as shown in FIG. 1 to cover the openings between both side rails 11. .

In the case of Fig. 1 (a), the cover in the form of a flat plate is joined using bolts, and Fig. 1 (b) is the case in which the cover in the form of an inclined surface having a high center is joined using bolts. In the case of (d), there is shown a case in which the cover of the flat form (with a vertical piece bent at both ends) is joined using a clamp instead of a bolt, but such a conventional cover has the following problems.

In the case of a flat cover, deflection due to its own load occurs, and a contact occurs between the cover and the cable in the center of the cable tray.As a result of this contact, a short circuit and a short circuit due to deterioration of the cable sheath and peeling of the sheath are caused. There is a risk. In addition, the cable tray and bolts or clamps should be combined to provide a separate fastening bolt or clamp, and stainless steel fastening bolts or clamps are used to prevent corrosion, which is a significant material cost increase factor. However, there is a problem in that the fastening time is excessively increased and the working time and cost increase.

In the case of the cover of the inclined surface, unlike the flat plate can prevent the deflection, but still has the problem of increased material cost, work time and cost required when combined with the cable tray.

In addition, such an inclined cover (or a flat plate having a vertical piece bent at both ends) may have covers of different sizes according to the size of the cable tray (that is, the distance (width) between the side rails 11). However, in the case of a cover made by drawing FRP (Fiber Reinforced Plastic), there is a problem that a drawing die should be provided for each standard.

The purpose of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to provide a cover for a cable tray to prevent sagging of the central portion.

Secondly, another object of the present invention is to provide a cover for a cable tray that is easy to assemble.

Third, another object of the present invention is to provide a cover for a cable tray that can be applied to various standards by making the most of one drawing die.

The composition of the present invention created to achieve the above object is as follows.

The present invention relates to a cover structure for covering the upper part of the cable tray for guiding the cable to the destination consisting of a left and right side rails having a cross-section of the 'c' shape and a rung (Rung) connecting them, the side rail (11) A pair of inclined panels 100 coupled to each upper end and arranged in a left-right symmetrical form, respectively, and forming inclined surfaces on both left and right sides; And a central connection member 200 coupled to each end of the pair of inclined panels 100 at a central upper portion of the cable tray to integrally connect the pair of inclined panels 100. When the inclined panel 100 is provided with an elastic force and a force is applied from both left and right sides toward the center, the inclination panel 100 is deformed and narrowed. Characterized in that to maintain.

Technical effects according to the present invention of the above configuration is as follows.

First, it is possible to prevent the sag of the center portion to prevent the interference of the top cover and the cable.

In other words, unlike the flat cover, the central cover protrudes from the inclined surface to prevent the sagging of the central part and the interference between the top cover and the cable, thereby preventing the risk of safety accident due to the cable damage. can do.

Second, there is no need to fasten a separate bolt when assembling the cable tray and the top cover, it is possible to perform the top cover installation more quickly and simply.

In other words, in the case of the present invention, a separate bolt or clamp is not used and a force is applied to the upper cover itself to narrow the distance between the coupling grooves 110, and then the coupling grooves 110 are formed at the upper ends of the side rails 11. When fitted, the coupling state is maintained between the coupling groove 110 and the upper end of the side rail 11 while being restored by the elastic force of the upper cover itself. In addition, the load of the upper cover itself also acts in the direction in which the upper ends of the side rails 11 close to the coupling groove 110 may further increase the coupling force. Therefore, even without a separate fastening means (bolts or clamps) can be maintained in a stable state can reduce the cost of the raw material (fastening means) and can be carried out more quickly and easily mounting the top cover.

Third, it is possible to manufacture a cover for a cable tray that can be applied to various standards by making the most of one drawing die.

In other words, in the case of the present invention, the left inclined panel 100 and the right inclined panel 100 are symmetrical in shape so that when the FRP is drawn out, the drawing for the drawing die and the inclined panel 100 for the center connecting member 200 is performed. Only one die is required. This is because the inclined panel 100 can be used in both left and right sides by drawing in the same form.

In addition, when the size of the cable tray (the distance between the left and right side rails 11) is changed, the conventional upper cover shown in FIG. 1 must be separately provided with a drawing die capable of drawing it according to its respective standard. .

On the contrary, in the case of the present design, even if the standard of the cable tray is changed in the case of the central connection member 200, one standard can be used as it is, and in the case of the inclined panel 100, the shape of the coupling groove 110 can be used as it is. Therefore, only the length of the inclination portion 120 may be changed and manufactured according to the standard.

Accordingly, the inclined portion 120 is provided with a draw die for the center connecting member and a draw die for the inclined panel 100 for manufacturing the inclined panel 100 that can be used for the cable tray of the largest standard, and the inclined portion 120 drawn out from the draw die for the inclined panel. Only the blocks (plates) inserted into the drawing die can be separated to meet the standard so that only the length of the sheet can be changed.

That is, it is possible to pull out the inclined panel 100 of various specifications with a single drawing die can reduce the manufacturing cost of the drawing die.

Hereinafter, with reference to the accompanying drawings a specific embodiment of the present invention will be described in more detail.

Figure 2 is a cross-sectional view of a specific embodiment of the present invention, the cable wired therein is not shown, Figure 3 shows a process of installing the top cover which is a specific embodiment of the present invention.

The present invention relates to a cover structure covering an upper portion of a cable tray configured to include left and right side rails 11 and a rung 22 connecting the left and right side rails 11 having a cross-section of a 'c' shape.

As shown in Figure 2, the upper cover of the present invention is composed of a central connection member 200 for connecting two inclined panels 100 into one.

The inclined panel 100 and the central connection member 200 may be made of various materials.

That is, in a specific embodiment of the present invention used a pulled (Pultrusion) FRP, but is not necessarily limited to the material of this embodiment, and in some cases, a synthetic resin such as plastic, various kinds of metal materials may be selected and used. .

FRP Pultruded molding means that glass fiber, which is a reinforcing material, is impregnated with a resin and then pulled through a heated mold with a certain shape and cured to be continuously formed. It refers to a continuous molding process for preparing a.

When using such a continuous molding process, it is possible to continuously produce the inclined panel 100 or the central connection member 200 having a constant cross-sectional shape as in the specific embodiment of the present invention.

Sloped panel 100 is provided with a coupling groove 110 is inserted into the upper end of the side rail (11) of the 'c' shape is coupled to the upper end of the side rail (11).

The shape of the coupling groove 110 should be formed to correspond to the shape of the upper end of the side rail 11, if a side rail 11 of a different shape from that shown in Figure 2 is used, 11) It is a matter of course that the shape of the coupling groove 110 to be appropriately changed according to the shape of the upper end.

The inclined panel 100 is composed of a coupling groove 110 and the inclined portion 120, the inclined portion 120 is bent in the upward direction in the coupling groove 110 extends.

Coupled to the upper left and right both sides of the cable tray of the inclined panel 100 configured as described above is arranged symmetrically, and serves as a roof forming an inclined surface in the upper left and right both sides of the cable tray.

Connecting the inclined panel 100 to one is the central connection member 200.

The central connection member 200 is coupled to the ends of each of the left and right pair of inclined panels 100 at the center upper portion of the cable tray serves as a central member for integrally connecting the pair of inclined panels 100.

Accordingly, the center connecting member 200 is formed by the left and right pair of inclined panels 100 formed by the left and right symmetric accommodating grooves 210 to accommodate the ends of each of the left and right inclined panels 100 as shown in FIG. 2. It is provided so that it may open at the same angle as an angle.

When the end of the inclined panel 100 is inserted into the receiving groove 210 is bonded (bonding) using an epoxy adhesive or the like.

Both the inclined panel 100 and the central connection member 200 are used in the FRP pull-molded product itself has an elastic force.

Therefore, as shown in FIG. 3, when a pair of left and right inclined panels 100 and a center connecting member 200 are applied to the center from left and right sides of the upper cover integrally assembled, deformation occurs to form a coupling groove on both sides. The distance between the (110) is narrowed to push the upper cover into the upper inside of the cable tray, and the force applied to the upper cover in a state where the position of the upper end of the coupling groove 110 and the side rails 11 coincides. When removed, the upper end of the side rail 11 is accommodated in the coupling groove 110 while being returned to its original shape by elastic force. When the installed top cover is separated from the cable tray, the reverse process of the process shown in FIG. 3 is performed.

As described above, the technical idea of the present invention has been described with reference to specific embodiments of the present invention, but the scope of protection of the present invention is not necessarily limited to these embodiments, and the scope of the present invention is not changed. Various design changes, addition or deletion of well-known technology, simple numerical limitations, material limitations, and local shape changes are clearly included in the protection scope of the present invention.
