Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slide-type cover that continuously covers an opening of a long trough-like or substantially ladder-like long storage body such as a cable rack, a cable duct, and a refrigerant pipe rack.
[0002]
[Prior art]
Conventionally, as a cover for continuously covering openings such as a cable rack for storing cables in a building or a refrigerant pipe rack for storing air-conditioning pipes, Japanese Patent Application Laid-Open No. 9-163439 previously proposed by the present applicant, The cover described in JP 2001-25128 A is used. These covers are formed by bending both longitudinal side edges of a flat top plate to form locking pieces for locking to the outside of the main girder or the like of the cable rack. Further, as another cover, a cover in which a top plate is bent into a roof shape is often used (for example, refer to Japanese Patent Application Laid-Open No. 2000-023327).
[0003]
When covering a rack, etc. with these covers, they are all used in combination with covers of regulated length, but because they are constructed according to the site, a size other than the regulated length is required. There is. In this case, a measure is taken such that a cover of a regulated length is cut and used, or a custom-made product having a size other than the regulated length is ordered from a manufacturer.
[0004]
Furthermore, when these covers are used to connect a cover having a flat top plate, the covers are connected in a state where the ends of the adjacent covers are in contact with each other. For example, according to the cover connecting method described in Japanese Patent Application Laid-Open No. 9-163538, the ends of the covers are brought into abutment with each other and connected by screwing a substantially U-shaped side fitting.
[0005]
On the other hand, in the case of a cover bent into a roof shape, it is necessary to provide a step at one end of the cover. When this type of cover is connected, one end of the cover is connected to the other step so as to overlap with the other step, thereby closing the gap between the connected portions.
[0006]
[Problems to be solved by the invention]
In the case where a cover of a regulated length is used by cutting it on site, the cut portion cut at the site does not become a straight line as accurately as the cover of the regulated length. For this reason, there is a case where an operation of straightening the cut portion by sanding is performed. However, if the operation cannot be performed in a straight line, a gap is generated in a portion where the cut end portions abut. Then, rainwater easily penetrates from the gap, and thus a construction for connecting a cover connecting material via a cut end described in JP-A-2001-25128 is also performed.
[0007]
However, such a series of operations, that is, cutting and polishing a cover of a regulated length at the site, and continuously covering the cover with a cover connecting material as necessary requires a great deal of labor and time. However, this type of cover construction has been delayed. There is also a means for ordering a cover of a length other than the standard as a custom-made product, but there is a disadvantage that it takes time from ordering to delivery.
[0008]
On the other hand, when using a roof-type cover, it is necessary to form a step portion in advance to reduce the gap at the connection end of the cover, so that the manufacturing cost of the cover is lower than that of a cover having a flat top plate. I was raising it.
[0009]
Therefore, the present invention has been created in order to solve the above-mentioned problems, and it is possible to continuously cover the cover with extremely simple work, and the waterproof effect of rainwater is high without using a cover connecting material. Further, it is an object of the present invention to provide a slide-type cover capable of suppressing the manufacturing cost of the cover.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a first means of the present invention is to provide a cover for continuously covering the upper opening of a substantially trough-shaped storage body P for storing a cable or a refrigerant pipe, And a pair of locking pieces 2 that are bent from both longitudinal side edges of the cover body 1 and overlap with the outside of the longitudinal side edge P1 along the longitudinal side edge P1 of the storage body P. The distance between the locking pieces 2 at one longitudinal end of the cover 1 is made smaller than the distance between the locking pieces 2 at the other end, and the distance between the locking pieces 2 is changed from one end to the other end of the cover 1. , One end having a narrow interval is a narrow end 4, the other end having a large interval is a wide end 3, and one wide end 3 of an adjacent cover is the other narrow end. The purpose is to adjust the length of the cover by slidably overlapping the upper surface of the portion 4.
[0011]
In the second means, the cover 1 uses a cover 1 having a flat upper surface.
[0012]
The cover body 1 of the third means is a means for solving the problem using the cover body 1 having a roof-shaped upper surface.
[0013]
According to the present invention, the length of the cover is adjusted by slidably overlapping one wide end 3 and the other narrow end 4 of the adjacent covers.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The sliding cover of the present invention is composed of a cover body 1 and a locking piece 2 and continuously covers the upper opening of the storage body P having a substantially gutter shape (FIGS. 1 and 4). reference).
[0015]
The storage body P is, for example, a substantially trough-shaped or substantially ladder-shaped storage body P such as a cable rack or a cable duct for storing a cable, or a storage body P such as a refrigerant pipe rack or a refrigerant pipe duct for storing a refrigerant pipe. Then, the slide type cover of the present invention is covered along the upper portion of the opening of the storage body P so as to be freely adjustable in length.
[0016]
The cover body 1 is a band-shaped part that covers the upper opening of the storage body. The cover body 1 includes, for example, a cover body 1 having a flat upper surface (see FIGS. 1 and 3) and a cover body 1 having a roof-like upper surface (see FIGS. 4 and 6). The flat type cover body 1 is mainly used as a cover for covering a cable rack or the like that stores cables, and the roof type cover body 1 mainly covers a refrigerant pipe rack or the like that stores refrigerant pipes or the like. Used as a cover. The sliding cover of the present invention is applied to any of these types of cover bodies 1.
[0017]
The locking piece 2 is formed by bending both longitudinal side edges of the cover body 1 (see FIGS. 3 and 6). The locking piece 2 is provided so as to overlap with the outside of the longitudinal side edge P1 of the storage body P. The distance between the opposing locking pieces 2 is slightly changed at one end and the other end of the cover body 1.
[0018]
That is, in the cover body 1, the distance between the locking pieces 2 at one longitudinal end is made smaller than the distance between the locking pieces 2 at the other end, and the distance between the locking pieces 2 is different from one end of the cover body 1. It is formed so as to gradually spread toward the end (see FIGS. 2 and 5). When one end having a small gap is the narrow end 4 and the other end having a large gap is the wide end 3, the wide end 3 of one adjacent cover is slid on the upper surface of the other narrow end 4. By freely polymerizing, the overall length of the cover is adjusted.
[0019]
As the material of the sliding cover of the present invention, any material can be selected, for example, melamine resin baked coating of hot-dip galvanized steel sheet, hot-dip galvanized finishing of mild steel sheet, stainless steel, galvalume steel sheet, and the like. At this time, the width of the narrow end portion 4 was set to 324 mm to 1024 mm when forming a cover with a total length of 1500 mm and a thickness of 1.6 mm using a hot-rolled mild steel sheet in a flat-plate type cover. In the case, the inner dimension between the locking pieces 2 of the wide end 3 is set to 330 mm to 1030 mm, and the difference between the inner dimension between the locking pieces 2 of the wide end 3 is set to 6 mm, so that the entire surface can be smoothly adjusted. The slide becomes possible.
[0020]
On the other hand, when forming a roof-type cover of the same material with a total length of 1500 mm and a thickness of 1.6 mm, when the width of the narrow end 4 is set to 324 mm to 1024 mm, the width of the locking piece 2 of the wide end 3 is reduced. By setting the size between 334mm and 1034mm and making the difference between the inner size between the locking pieces 2 of the wide end 3 10mm, the entire surface can be slid, eliminating restrictions on length adjustment, Can be adjusted.
[0021]
【The invention's effect】
The present invention achieves the original object by being configured as described above.
[0022]
That is, the gap between the locking pieces 2 is made smaller than the gap between the other locking pieces 2 and the gap between the locking pieces 2 is formed so as to gradually decrease from one side to the other side. The narrow end 4 is used, the other end with a large interval is used as the wide end 3, and one wide end 3 of the adjacent cover is slidably overlapped on the upper surface of the other narrow end 4 to cover the length of the cover. The length of the cover can be adjusted with a very simple operation.
[0023]
As a result, operations such as cutting a cover of a regulated length on site like a conventional cover, sanding the cut part, constructing the cover connecting material at the cut end, and ordering special order products are required. There is no need at all, and we have succeeded in rationalizing the work to cover the container P and significantly shortening the construction period.
[0024]
In addition, according to the second and third aspects, the length of the cover body 1 having a flat top surface as well as the cover body 1 having a roof-shaped top surface can be similarly adjusted. Therefore, it is not necessary to form a step on the cover body 1 having a roof-shaped upper surface, and the manufacturing costs of various covers can be suppressed. In addition, the purpose of use of the cover is not limited to one type, such as use in a rack for storing cables, a rack for storing refrigerant tubes, and the like.
[0025]
As described above, according to the present invention, it is possible to continuously cover the cover with an extremely simple operation, and the waterproof effect of rainwater is high without using a cover connecting material, and the manufacturing cost of the cover can be reduced. It produces various effects such as being able to perform.
