In the conventional ceiling structure, the ceiling plate mounting member a is a long member arranged between adjacent base materials 1 or across one or a plurality of base materials. Its weight is extremely heavy. Therefore, it is difficult to position and fix the ceiling plate mounting member a to the base material 1, which reduces workability. Further, since the ceiling plate 2 only rides on the flange portion b of the hat-shaped ceiling plate mounting member a and the base material 1, there is a problem that the ceiling plate 2 is easily lifted from the flange portion b and the base material 1 due to wind. Yes, to prevent this, mount the ceiling plate 2 on the flange b.
It requires extra work such as having to fix it with bolts etc.

The present invention has been made in view of the above circumstances, and by devising a structure for fixing a ceiling plate mounting member and a base material, and a structure of the ceiling plate mounting member itself, the ceiling plate mounting member and the ceiling are mounted. An object of the present invention is to provide a ceiling structure that can improve workability when attaching a plate and that does not cause a situation in which the attached ceiling plate floats up.

[0006]

According to the ceiling structure of the invention of claim 1, a leg portion of a short fitting having an engaging portion at a lower portion is provided on a base material such as a beam or a purlin, and is attached to an end portion. The ceiling plate is mounted by engaging the engaging portion of the ceiling plate mounting member with the engaging portion of the ceiling plate, which includes the groove portion having the joint portion and capable of fitting the end portion of the ceiling plate over the entire side length. The member is attached to the base material, and the end portion of the ceiling plate is held in a fitted state in the groove of the ceiling plate attachment member.

According to the ceiling structure of the invention of claim 2, in addition to the structure of the invention of claim 1, the leg portions of the fixture are attached to the bottom plate portion of the frame while being guided.

[0008]

In the invention of claim 1, the mounting position of the ceiling plate mounting member on the base material is determined by the mounting position of the mounting tool on the base material. Since the fixture is short and relatively light in weight, if such a fixture that is easy to handle is accurately positioned and fixed to the base material, the ceiling plate attachment member will not have the engaging portion at its end. The ceiling plate mounting member is accurately positioned with respect to the base material only by engaging with the engaging portion of the mounting tool. Moreover, the end portion of the ceiling plate, which is held in the groove portion of the ceiling plate mounting member in a fitting manner, is prevented from rising by the groove wall above the groove portion.

According to the second aspect of the invention, since the fixture is positioned by the frame, it is not necessary to position the fixture with respect to the base material.

By the way, when the space between the base materials 1 is wide, it is generally necessary to use the ceiling plate 2 having a large size accordingly. However, if the ceiling plate 2 is large, the ceiling plate 2 tends to droop due to its own weight. In addition, when the base material 1 has a large mutual interval, it may be necessary to separately work on a scaffold. However, there are cases where such a need can be eliminated by using the ceiling plate mounting member 5. less than,
This point will be described.

As shown in FIGS. 2 and 3, the ceiling plate mounting members having the same cross-sectional shape are disposed between the ceiling plate mounting members 5 and 5 arranged at a right angle to the base material 1 at a predetermined interval. 5A ... Are laid in parallel to the base material 1.

In this embodiment, the engaging piece 47 is formed by forming the notch 48 in the leg portion 46 of the engaging portion 42 of the fixture 4, and the engaging piece 47 is fitted into the opening 36 of the frame 3. Although the fitting 4 is positioned by means of the above, the engaging piece 47 may be eliminated by forming a notch over the entire portion of the leg 46 excluding both ends. In this case, if the width of the cut, that is, the mutual distance between the leg portions 46 on both sides of the cut is matched with the width of the bottom plate portion 31 of the frame, both ends of the leg portion 46 are fitted into the bottom plate portion 31 of the frame 3. As a result, the leg portions 46 of the fixture 4 are guided by the bottom plate portion 31 and are attached in a positioned state. In this case, the opening 36 of the frame 3 can be omitted. Further, instead of the opening 36, a pair of slit-shaped openings corresponding to the pair of engaging pieces 47, 47 may be formed, and the engaging piece 47 may be fitted into the slit-shaped opening. Similarly, the side plate portion 3 of the frame 3

Further, as shown by a phantom line in FIG. 3, the beam 9 of the ceiling plate mounting member 5 is covered and fixed with the clip 9, and the ceiling plate 2 is pressed by the presser seat 91 of the clip 9. It is possible to more surely prevent the floating when the wind is blown by the wind. It is to be noted that the fixture 4 and the frame 3 attached to the base material 1 as shown in FIGS. 3 and 5 may be fixed by tightening with a bolt inserted through them and a nut screwed to the bolt. In that case, it may not be necessary to weld and fix the fixture 4 to the frame 3 or the like.

Since the frame 3 described in the above embodiment is a member for supporting the folded plate 8 through the suspension 7, it is similar to the roof receiving frame e having the shape shown in FIG. It can be replaced with a frame having a shape (for example, a frame having a structure in which a folded roof plate is fixed by a sword bolt instead of the hanger i). If you do so, the fixture 4
Although it is necessary to position and accurately fix the base material 1 to the base material 1, the mounting tool 4 is easy to handle because it is short and lightweight as described above. Will not be difficult. In addition,
When the roof receiving frame e of FIG. 6 is used, the fixture 4 is fixed directly to the base material 1 below the mountain portion of the roof receiving frame e, or is attached at the valley portion of the roof receiving frame e via the valley portion. The tool 4 may be fixed to the base material 1. The same applies when a frame having a shape similar to the roof receiving frame e is used.
