Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a roof connecting portion for covering a roof rack on a refrigerant pipe rack used for a piping duct of a building air conditioner or a cable rack installed on the roof of a building. Cover construction structure.

[0002]

2. Description of the Related Art The present applicant has already proposed a roof-type rack cover device (Japanese Patent Laid-Open No. 7-107637). This cover device prevents the cover from bending due to its own weight, and allows the covers to be connected to each other in a close state.

[0003] Thereafter, the roof rack cover was improved and, in addition to the roof cover used for straight lines, FIG.
A cover having a different diameter shown in (a) and an L-shaped branch cover shown in (b) are used in combination. These different-diameter covers and L-shaped branch covers are provided with a flange 10 to be overlapped on a connecting portion with an adjacent straight cover, and the flange 10 is overlapped on a connecting portion between the covers so that no gap is generated. It is.

[0004]

However, in the conventional cover having a different diameter or an L-shaped branch cover, there has been a problem that the construction conditions of the roof-shaped cover are partially restricted.

[0005] For example, it was not possible to directly connect a cover having a different diameter shown in FIG. 7A to an L-shaped branch cover shown in FIG. 7B. This is because the flanges of the cover having the different diameter and the L-shaped branch cover interfere with each other, so that they cannot be directly connected to each other.
As a result, the construction conditions of the roof-shaped cover were partially restricted.

[0007] Further, the reduced diameter cover shown in FIG. 7 (a) connects the ridge line of the adjacent straight cover and the ridge line 20 of the reduced diameter cover so as to coincide with each other. It must always be installed in the center of the rack. Therefore, as shown in FIG. 3, the cover having the different diameter cannot be installed on one side of the rack, and the construction condition of the roof-shaped cover is also partially limited here.

In the case of the cover having the different diameter shown in FIG. 7A, the cover having the different diameter is manufactured for each size having a different diameter, so that the number of types of the cover having the different diameter becomes extremely large, and the manufacturing cost is increased. Many inconveniences have also occurred in transportation work and inventory management.

Further, when the cover having the different diameter shown in FIG. 7A is to be formed for one side, the manufacturing process must be more complicated than that of the conventional cover having the different diameter, and the diameter of the cover must be increased as described above. Since different diameter covers are manufactured for different sizes, it is not realistic to manufacture a single diameter cover for one side.

Accordingly, the present invention has been made to solve the above-mentioned problems, and the installation of a roof cover having a different diameter is not restricted by construction conditions, and a rack connection that can be installed according to the conditions of the site is possible. The purpose of the present invention is to provide a roof-type cover connection structure for a section.

The cover S is placed on the upper surface of the support 1 so that the roof covers S having different diameters are connected to each other.

Further, the third means is that, in the connection structure of the roof-shaped cover S, the closing fitting 2 for closing the opening of the large-diameter rack P1 is connected between the large-diameter rack P1 and the small-diameter rack P2. Means for solving the problem.

The fourth means is a support fitting 1 for supporting a connection portion at which a rack P intersects with a roof-shaped cover S along a width direction of an inner surface of the roof-shaped cover S.
And the support bracket 1 is erected at the open end of the other rack P, which abuts against the side surface of the one rack P, and the open end of the linear roof-shaped cover S covering the other rack P is It is to be placed on the upper surface of the support fitting 1 and to close the open end of the roof-shaped cover S with the side surface of the support fitting 1.

According to the present invention, the connecting portion of the racks P having different diameters supports the roof-shaped cover S for covering the large-diameter rack P1 with the support fitting 1 erected at the end of the large-diameter rack P1. The open end of the roof-shaped cover S that covers the rack P2 is covered with the support fitting 1 in a continuous state. At this time, the roof-shaped cover S covering the small-diameter rack P2 is supported and reinforced by erecting the support fitting 1 at the end of the small-diameter rack P2. The support member having a substantially mountain shape for supporting the end of the roof cover closes the open end of the roof cover having a different diameter.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting structure according to an embodiment of the present invention;

Reference numeral S shown in the figure is a roof-shaped cover having a different diameter. This roof-shaped cover S is formed for a straight line, and variously formed according to the width of the rack P (see FIG. 1).

Reference numeral 1 denotes a support bracket that supports the roof-shaped cover S for a straight line along the width direction of the inner surface. The support fitting 1 is provided between the parent girders of the rack P and is erected above the rack P. The support fitting 1 which is formed in a substantially mountain shape has an opening of the roof-shaped cover S. It is formed so as to substantially match the shape (see FIG. 1). The support fitting 1 is also formed in a plurality of sizes in accordance with the roof-shaped cover S.

Then, a roof-shaped cover S for covering a connection portion between racks P having different diameters is continuously formed in the following structure.

First, the supporting bracket 1 is attached to the end of the large-diameter rack P1.
And a linear large-diameter roof-shaped cover S1 for covering the large-diameter rack P1 is placed on the support fitting 1. And a small-diameter roof-shaped cover S2 for a straight line covering the small-diameter rack P2.
Is connected to the side surface of the support fitting 1. At this time, preferably, when the opening end of the small-diameter roof-shaped cover S2 is brought into contact with the support fitting 1, the gap between the continuous portions of the roof-shaped covers S can be eliminated, thereby preventing rainwater and dust from entering. it can. Also, large diameter roof cover S
One end may be extended toward the small-diameter roof-shaped cover S2, so that the ends of the roof-shaped cover S are overlapped. In this case, the opening end of the small-diameter roof-shaped cover S2 may be separated from the support fitting 1.

In the illustrated example, in addition to the large-diameter support fitting 1A for supporting the large-diameter roof cover S1, a small-diameter roof cover S2 is provided.
