Description of the Related Art Conventionally, when a wide rack such as a refrigerant pipe rack R installed on the roof of a building is covered, various covers are provided on the entire cover R1 in order to maintain the strength of the cover R1 itself. A reinforcing rib R2 was provided (see FIG. 5).

[0003] Further, since the refrigerant pipe racks R of this kind are wide in width, the refrigerant pipe racks R cross over the upper part of the refrigerant pipe rack R so that an operator can get over the installed refrigerant pipe rack R and perform other work. Bridge S was installed (see FIG. 5).

On the other hand, in the case of a cable rack or the like installed outdoors, a rack cover for covering the cable rack is sometimes used (see Japanese Utility Model Laid-Open No. 62-19018 and Japanese Utility Model Laid-Open No. 2-125515). ).

[0005]

However, even if the strength of the cover is increased, it is difficult to keep the connecting portions of the covers in close contact with each other. Then, it was necessary to screw these covers and the fixed joint together. Therefore, the work of connecting the covers is a major cause of delay in the work of covering the cover.

In addition, with the conventional cover, it is difficult to reinforce the upper part of the cover so that a worker can cross it, and the installation of a bridge for traversing the rack is indispensable for the subsequent work. The work of installing this bridge is also an issue of work rationalization.

On the other hand, a cover for a cable rack to be installed outdoors is provided with a mountain-shaped slope or a flat cover with a different height via a spacer to improve drainage. And it was difficult to strengthen the top of the cover so that workers could cross it.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a cover device for a large rack, which enables a large rationalization of a cover operation for a large rack.

[0009]

In order to achieve the above object, a first means of the present invention is that a plate is bent into a mountain-shaped cross section,
A cover body 1 in which a ridge 1A is arranged along the longitudinal direction of the rack P, and a cover body 1
Support member 2 for supporting the cover body 1 arranged along the lower surface of the
And The support bracket 2 includes a locking hook 2A that locks to the outside of the rack opening, a contact piece 2B that contacts an opposing inner edge of the rack opening, and a lower surface of the cover 1 along a mountain shape. It has a plurality of support protrusions 2C of different supporting heights, and the upper surface of the cover body 1 in the range supported and reinforced by the support fitting 2 is used as the sidewalk surface for traversing the rack.

Further, the upper surface of the cover body 1 supported by the support bracket 2 is used as a sidewalk surface for traversing the rack within a range supported and reinforced by the support bracket on the upper surface of the cover body 1, and a sidewalk surface is provided on the upper surface of the cover body 1. Is provided as a means for solving the problem.

[0011]

That is, according to the present invention, the cover body 1 bent into a mountain-shaped cross section strengthens the structure of the cover body 1 itself. Then, the support bracket 2 erected between the parent girders P1 of the rack P reinforces the connection portion of the cover body 1.

The support fitting 2 reinforces the structure of the cover 1 with its support protrusions 2C, and reinforces the structure of the opening of the rack P with a contact piece 2B that contacts the opposing side edge of the parent girder P1.

The upper surface of the cover body 1 reinforced by the support fittings 2 is a sidewalk surface traversed by an operator, and the display section 1C displays this sidewalk surface.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings.

Reference symbol P is a rack such as a refrigerant pipe rack used for a piping duct of a building air conditioner or a large cable rack having a width exceeding 1 m (in the illustrated example, a ladder-shaped refrigerant pipe used for a piping duct is shown). Rack). The cover 1 covers the opening of the rack P (see FIG. 1).

The cover body 1 is formed by bending a plate body into a mountain-shaped cross section and ridges 1A are arranged along the longitudinal direction of the rack P. The use of a steel plate coated with hot-dip zinc is planned. In addition, other metal plate members, plastic plate members, and the like can be used. In the illustrated example, the cover body 1 is provided with locking pieces 1B that are bent at both side edges of the rack P in contact with the parent girder P1 and are parallel to the ridge line 1A (see FIG. 1). And
The overlapping piece 1D is bent at one end of the cover body 1 so that the connecting portions of the cover bodies 1 overlap. Further, in order to screw the cover body 1 to the opening of the rack P with the fastening screw 3, a screw insertion hole 1 </ b> E is formed in a portion located above the rack P.

The support fitting 2 is provided between the openings of the rack P and is disposed along the lower surface of the cover body 1. In the illustrated example, the support fitting 2 is provided between the parent girders P1. A locking hook 2A that locks the outer side of the main girder P1 and contact pieces 2B that abut on opposing inner edges of the main girder P1 are provided at both ends of the rod. The illustrated support fitting 2 uses a lip grooved steel as a rod, and has hook-shaped locking hooks 2 at both ends of the rod.
A is provided, and the end of the rod is used as the contact piece 2B. Furthermore,
A plurality of support protrusions 2C for supporting the lower surface of the cover body 1 from the rod material are protruded. The support projection 2C is for supporting along the inclined inner side surface of the cover 1 having a mountain-shaped cross section, and its length is changed depending on the position where the cover 1 is supported (see FIG. 1). At this time, the support projection 2C shown in FIG. 2 uses a bolt that penetrates the rod material.
As shown in the figure, the fixing nut 2D is welded to the surface of the rod,
A bolt is screwed to this fixing nut 2D to form a support projection 2
C may be used.

The method of using the support fitting 2 is as follows.
, And in particular, is reinforced so that the overlapping piece 1D of the cover body 1 is superimposed in a close state.

Further, the cover body 1 is strengthened by arranging a plurality of support fittings 2 at a narrow interval, and the upper surface of the cover body 1 located between these support fittings 2 can be used as a sidewalk surface (FIG. 1). reference). This sidewalk surface allows a worker to pass over the cover body 1 after the rack P is covered, and is different from a conventional bridge S for crossing a rack (see FIG. 5). Therefore, a display unit 1C is provided on the upper surface of the cover body 1 to indicate the position of the sidewalk surface (see FIG. 3). The illustrated display unit 1C is a striped display unit 1C imitating a crosswalk.
Although the display unit 1C has a shape imitating a footprint, the shape of the display unit 1C is appropriate. The display unit 1C may have any display means such as sticking a sticker or painting the surface of the cover 1.

[0020]

According to the present invention, the above-mentioned configuration achieves the original object. That is, according to the first aspect, the structure of the cover body 1 can be strengthened. Therefore, it is possible to prevent the cover bodies 1 from bending due to their own weight, and to connect the cover bodies 1 in a close state.
From this, it is possible to prevent water leakage or the like from the connecting portion caused by the bending of the cover body 1. In addition, since the opening of the cover 1 can be reinforced by the support fitting 2, when many pipes and pipes are stored in the rack P, the rack P may be bent by this load, and the opening of the rack P may be narrowed. Can be resolved.

Further, since the support fitting 2 can forcibly shape the bending of the cover body 1, for example, a bending caused by plating, such as a steel sheet subjected to hot-dip galvanizing, or
The support metal 2 can correct the bending or the like in storage or transportation with the cover 1 stacked.

Further, it is not necessary to install the conventional bridge S for traversing the racks, and the operator can directly traverse the cover 1, so that the work can be streamlined.

According to the second aspect, the reinforced position of the cover body 1 can be known on the display section 1C for displaying the sidewalk surface on the upper surface of the cover body 1, so that extremely safe use becomes possible.

As described above, according to the present invention, it is possible to achieve various industrially useful effects such as a large rationalization of the operation of covering a large rack.
