Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening structure of a corrugated plate structure, and in particular, it is possible to easily form a rectangular opening for a lighting window or the like in the corrugated plate structure. The present invention relates to an opening structure of a corrugated plate structure in which stress concentration does not occur in the opening.

2. Description of the Related Art Conventionally, as shown in FIG. 8, for example, for the purpose of daylighting a structure 1 such as a warehouse, which is constructed by a corrugated steel plate curved in an arc shape in a direction orthogonal to a corrugating direction. The rectangular window 2 was formed as follows. That is, as shown in FIG. 9, a part of the corrugated plate constituting the structure is cut into a rectangular shape by gas cutting or the like to form the opening 3
The plate-shaped edge member 4 is welded to the edge of the opening 3 thus formed, and the transparent plate 5 such as a glass plate or a transparent resin plate is attached in the edge member 4. Hereinafter, this structure is referred to as Prior Art 1.

As another structure, as shown in FIGS. 10 and 11, a fixed frame 6 having a rectangular opening 9 and the same shape and the same curvature as the corrugated plate of the structural portion, and the fixed frame 6 are formed. A window unit including a plate-shaped edge member 7 fixed to the edge of the opening 9 and a transparent plate 8 such as a glass plate fixed in the edge member 7 is manufactured in advance. The fixing frame 6 is superposed on a predetermined portion of the structure and bolted.
Hereinafter, this structure is referred to as Prior Art 2.

[0004]

However, the above-mentioned prior arts 1 and 2 have the following problems, that is, the edge members 4 and 7 are accurately positioned at the edges of the openings 3 and 9 without any gap. In order to fix it to, it is necessary to cut the corrugated steel sheet into an accurate rectangular shape. In this case, it is easy to cut the corrugated steel sheet in a direction orthogonal to the corrugating direction, but it is not easy to accurately and linearly cut along the corrugating direction.
Therefore, it is indispensable to rework the cut surface after cutting, and it takes a lot of time and labor to attach the window.

In the prior arts 1 and 2, the stress acting on the structure due to wind, snow, etc. is mainly caused by the openings 3, 9
Acts on the lower corners of the. Therefore, this portion is easily damaged.

In the prior art 2, it takes time to manufacture the window unit, and moreover, it is not easy to align the bolt holes when the fixing frame 6 is bolted to the structure 1.

Therefore, it is an object of the present invention, when forming an opening in a corrugated plate that constitutes a structure, that it is not particularly necessary to finish the cut surface in the corrugating direction with high precision, and
An object of the present invention is to provide an opening structure formed in a corrugated plate structure that can prevent stress from being concentrated on the corners of the opening.

[0008]

According to the present invention, there is provided a corrugated plate structure constructed of corrugated plates having a rectangular opening formed as a window or the like. Upper and lower U-shaped edge members fitted to the upper and lower edges of the opening, and at least one of the upper and lower U-shaped members fitted to the upper and lower edges and the front and back edges of the opening. The upper and lower spacing members are inserted into a gap formed between the upper and lower spacing members and are fixed to the structure, and the lengths of the upper and lower spacing members are the upper and lower edge portions of the opening. It is characterized by being longer than the length.

Another feature of the present invention is that the upper U-shaped member fitted in the upper edge of the opening has a drainage hole, and the drainage hole is a valley portion of the structure. It is formed in the position of.

Still another feature of the present invention is that at least one of the upper and lower spacers is L-shaped steel or flat steel.

[0011]

[Function] After cutting the corrugated plate to form a rectangular opening in the structure, if a U-shaped edge member is fitted into the upper and lower edges of the opening, the corrugated plate cut surface in the corrugating direction is raised. Eliminates the need to finish with precision. Moreover, if a spacer that is longer than the length of the lower edge of the opening is inserted between the lower U-shaped member and the front surface of the edge of the opening, and the spacer is fixed to the structure, the stress applied to the structure is reduced. No more concentration on the lower corner of the opening.
