Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slide type cover that continuously covers an opening of a long storage body having a substantially bowl shape or a substantially ladder shape such as a cable rack, a cable duct, or a refrigerant pipe rack.
[0002]
[Prior art]
Conventionally, as a cover for continuously covering an opening of a cable rack for storing cables in a building or the like, or a refrigerant pipe rack for storing air-conditioning pipes, Japanese Patent Laid-Open No. 9-163539 previously proposed by the present applicant, The cover described in JP 2001-25128 A is used. These covers are formed by bending the longitudinal side edges of the flat top plate to form the locking pieces that are locked to the outside of the main rack of the cable rack. In addition, many other types of covers in which the top plate is bent into a roof shape are also used (see, for example, Japanese Patent Application Laid-Open No. 2000-023327).
[0003]
When covering a rack, etc. with these covers, all of them are used in combination with a cover with a regulated length, but since it is 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 the cover having a regulated length is cut and used, or a custom-made product having a size other than the regulated length is ordered from the manufacturer.
[0004]
Further, when these covers are used to connect a flat type cover with the top plate, they are connected in a state in which the adjacent cover ends are abutted. For example, according to the cover connection method described in Japanese Patent Application Laid-Open No. 9-163539, the end portions of the cover are brought into contact with each other, and the connection is made by screwing a substantially U-shaped joint on the side.
[0005]
On the other hand, in the type of cover bent into a roof shape, it is necessary to provide a step at one end of the cover. And when connecting this type of cover, it connects so that the one edge part attached may be piled up on the other step part, and the gap of a connection part is obstruct | occluded.
[0006]
[Problems to be solved by the invention]
When a cover with a regulated length is cut and used at the site, the cut part cut at the site does not become an exact straight line like a cover with a regulated length. For this reason, there is a case where an operation for straightening the cut portion is performed. However, if the straight portion cannot be obtained by this operation, a gap is generated at a portion where the cut end portions are abutted. Then, rainwater can easily enter from the gap, and therefore, a construction for connecting the cover connecting material described in JP-A-2001-25128 through the cut end is also performed.
[0007]
However, these series of operations, that is, cutting the regulated length of the cover on site, polishing, and continuously covering the cover with a cover connecting material as necessary, require a great deal of labor and time. , This kind of cover construction was delayed. In addition, there is means for ordering a cover with a length other than the standard as a custom-made product, but there is a disadvantage that it takes time from the ordering to delivery.
[0008]
On the other hand, when using a roof-type cover, it is necessary to form in advance a step that reduces the gap at the connection end of the cover, so the manufacturing cost of the cover is lower than that of a cover with a flat top plate. It was higher.
[0009]
Therefore, the present invention has been created to solve the above-mentioned problems, and it is possible to continuously cover the cover with extremely simple work, and the rainwater waterproofing effect is high without using a cover connecting material. And it aims at provision of the slide type cover which can hold down the manufacturing cost of a cover.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the first means of the present invention is a cover for continuously covering the upper opening portion of the housing body P having a substantially bowl shape for housing 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 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 the longitudinal end of the cover body 1 is made narrower 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 of the cover body 1 to the other end. The narrow end 4 is the narrow end 4, the wide end 3 is the wide end 3, and one wide end 3 of the adjacent cover is the other narrow end. The length of the cover is adjusted by slidably overlapping the upper surface of the portion 4.
[0011]
In the second means, the cover body 1 uses a cover body 1 having a flat upper surface.
[0012]
The cover body 1 of the third means uses the cover body 1 having a roof shape on the upper surface as means for solving the problem.
[0013]
According to the present invention, the length of the cover is adjusted by slidably superposing one wide end portion 3 and the other narrow end portion 4 of the adjacent covers.
[0014]
DETAILED DESCRIPTION OF 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 housing P having a substantially bowl shape (FIGS. 1 and 4). reference).
[0015]
The storage body P is, for example, a substantially bowl-shaped or substantially ladder-shaped storage body P such as a cable rack or cable duct that stores cables, or a storage body P such as a refrigerant tube rack or refrigerant tube duct that stores refrigerant tubes. Then, the slide type cover of the present invention is covered along the upper part of the opening of the storage body P so as to be adjustable in length.
[0016]
The cover body 1 is a strip-shaped part that covers the upper opening of the storage body. Examples of the cover body 1 include a cover body 1 having a flat upper surface (see FIGS. 1 and 3) and a cover body 1 having a roof shape on the upper surface (see FIGS. 4 and 6). The flat plate type cover body 1 is mainly used as a cover for covering a cable rack or the like for storing cables, and the roof type cover body 1 is mainly for covering a refrigerant pipe rack or the like for storing refrigerant pipes or the like. Used as a cover. The slide type 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 the 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 in width between 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 end in the longitudinal direction is narrower than the distance between the locking pieces 2 at the other end, and the distance between the locking pieces 2 is different from the one end of the cover body 1. It forms so that it may spread gradually toward an edge part (refer FIG. 2, FIG. 5). Then, if one end portion with a narrow interval is a narrow end portion 4 and the other end portion with a wide interval is a wide end portion 3, the wide end portion 3 of one adjacent cover is slid onto the upper surface of the other narrow end portion 4. The length of the whole cover is adjusted by freely polymerizing.
[0019]
As a material of the slide type cover of the present invention, for example, any material such as a melamine resin baked coating of a hot dip galvanized steel sheet, a hot dip galvanized finish of a hot rolled mild steel sheet, stainless steel, a galvalume steel plate can be selected. At this time, in the flat type cover, when the hot galvanized finish of the hot rolled mild steel plate was used and the cover having a total length of 1500 mm and a thickness of 1.6 mm was formed, the width of the narrow end portion 4 was set to 324 mm to 1024 mm. In this 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 from the inner dimension between the locking pieces 2 of the wide end 3 is set to 6 mm. 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, if the width of the narrow end 4 is 324 mm to 1024 mm, the inside of the locking piece 2 of the wide end 3 By setting the dimension to 334mm to 1034mm and the difference between the inner dimension between the locking pieces 2 of the wide end 3 to 10mm, it is possible to slide the entire surface, eliminate the restriction of length adjustment, and to any length 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 distance between the one locking piece 2 is made narrower than the distance between the other locking pieces 2 and the distance between the locking pieces 2 is gradually narrowed from one side to the other. The narrow end 4 is used as the wide end 3 at the other end with a wide interval, and one wide end 3 of the adjacent cover is slidably overlapped on the upper surface of the other narrow end 4 so as to cover the length of the cover. Therefore, the length of the cover can be adjusted by an extremely simple operation.
[0023]
As a result, the work of cutting the regulated length of the cover like the conventional cover, the work of rubbing the cut part, the construction using the cover connecting material at the cut end, the ordering of custom products, etc. It was no longer necessary, and it succeeded in rationally shortening the construction period by rationalizing the container P cover work.
[0024]
Moreover, according to the second and third aspects, the length of the cover body 1 having a flat upper surface as well as the cover body 1 having a roof shape on the upper surface can be similarly slid and adjusted. Therefore, it is not necessary to form a stepped portion on the cover body 1 having a roof shape on the upper surface, and manufacturing costs of various covers can be suppressed. Moreover, since the use purpose of the cover is not limited to one type, such as a rack for storing cables or a rack for storing refrigerant pipes, it can be used for various types of storage bodies P.
[0025]
As described above, according to the present invention, it is possible to continuously cover the cover with an extremely simple work, and the rainwater has a high waterproofing effect without using a cover connecting material, and the manufacturing cost of the cover is suppressed. This produces various effects such as the ability to
