[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tight frame suitable for attaching a ceiling plate to an upper surface of a beam.

[0002]

2. Description of the Related Art A tight frame is used for laying a folding plate having an uneven shape on a beam material. The tight frame is usually fixed at a position on the beam material corresponding to the convex mountain portion, and a suspension member or a sword point is used. The folded plate is roofed via bolts and the like.

[0003]

However, in some cases, it is necessary to attach a ceiling plate to the upper surface side of the beam for the purpose of heat insulation or the like. In this case, it is only necessary to attach a ceiling plate between tight frames arranged at predetermined intervals on the same beam, but it is not necessary to fix the ceiling plate between beams arranged in the gradient direction of the roof. And the mounting condition is not stable. Therefore, it is conceivable to hang long rafters between beams and attach ceiling boards between these rafters.

However, since both the rafters and the tight frame are fixed on the beam, the tight frame hinders the installation of the ceiling plate. Therefore, the present invention aims to provide a tight frame to which a ceiling plate can be attached.

[0005]

Means for solving the above-mentioned problems will be described with reference to FIG. 3 of the embodiment. The structure is fixed on a beam member 10 and folded plates 16 and 16 are upward. The tight frame 1 to be roofed ,
Hit the main body 2 into a predetermined shape corresponding to the tight frame 1.
Pull the metal substrate 2a to the upper and lower ends of the left and right sides.
The receiving plate 4 and the supporting plate 5 are bent and the metal substrate 2
a in the left or right middle position or the left and right part
A long step 23a or a rib 43a is formed, and the beam 1
A support arm 3 for supporting rafter members 14, 14 for receiving edges of the ceiling plates 15, 15 is attached to a lower portion of the tight frame 1 main body 2 so that the ceiling plates 15, 15 are attached to the upper surface side of the tight frame 1. The tight frame 1 is formed to have an appropriate length along the gradient direction of the folding plate.

[0006]

According to the above construction, when the tight frame is fixed on the beam, the rafter member may be supported by the support arm of the tight frame. Attachment of the ceiling plate can be performed to this rafter member.

[0007]

As a result of the above, according to the present invention, the support arm is provided at the lower portion of the tight frame so that the rafter member receiving the edge of the ceiling plate can be supported, so that it is stable and has good appearance. Ceiling plate can be installed in any condition. Moreover, in the construction, the rafters
Position is set by the positioning of the tight frame
Therefore, workability is improved.

[0008] Further, the body of the tight frame itself,
At the middle position on the left or right, or on the left or right part,
Or the tight frame body is reinforced.
It is.

[0009]

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an exploded perspective view showing a tight frame 1. The tight frame 1 includes a main body 2 and a support arm 3 fixed to a lower portion of the main body 2.

The main body 2 is formed by bending a metal substrate 2a punched into a shape as shown in FIG. The shape is a left-right symmetrical shape, and the receiving plates 4 and 4 and the supporting plates 5 and 5 are formed at the upper end and the lower end at predetermined intervals. In addition, an insertion hole 6 through which the above-mentioned support arm 3 is inserted is formed at a lower middle position in the left-right direction, and burring holes 7 for fixing the support arm 3 are formed on both sides thereof. At the upper part, square holes 8, 8 for attaching the suspension elements are formed.

The metal substrate 2a is folded in either a mountain or a valley at the broken line and the alternate long and short dash line shown in the figure. Then, at the left and right intermediate positions, the support arm 3 is shifted by the thickness of the metal substrate 2a and the support arm 3 so that the mountain-folded side is closer to the front, and the support arm 3 can be inserted into the above-described insertion hole 6. I do.

The above-mentioned support arm 3 is formed in a strip shape having an appropriate length as shown in FIG. 1 and is inserted through the insertion hole 6 of the main body 2 so that the lengths of the projecting portions 3a are uniform. The burring holes 9, 9 are also formed at the positions corresponding to the burring holes 7, 7 when they are set.

The fixing between the main body 2 and the support arm 3 is performed as follows.
As described above, it does not depend on burring, but may be performed by an appropriate method, either by welding or by using a bolt and nut. As shown in FIG. 3, the tight frame 1 configured as described above fixes the lower end support plates 5 and 5 at predetermined positions on the beam member 10 with the support arm 3 facing the slope direction of the roof, and A hook 11 is fixed to one of the square holes 8 formed in the upper part by bolt nuts 12 and 13. And rafter members 14, 14 corresponding to the length between substantially beam members 10
Is supported and attached to the protruding portions 3a of the support arm 3. The rafter members 14, 14 have a substantially inverted V-shaped cross section, have an insertion groove 14a at an intermediate portion, and have receiving portions 14b, 14b projecting in the left-right direction at the lower end.

The ceiling boards 15, 15 are attached by the above-mentioned rafter members 14, which are supported by the projections 3a, 3a of the support arm 3.
Folding plate 1 for supporting the edges on the receiving portions 14b, 14b of 14 and fixing to the suspenders 11 of the tight frame 1
It is performed by pressing down from above at the valleys 16a, 16a. In addition, the above-mentioned ceiling boards 15 and 15 are rafter members 14,
14 is a band shape having a width dimension corresponding to the interval of 14. The extension in the gradient direction of the roof may be performed, for example, at the beam 10 position. Although the decorative sheet 15b made of vinyl chloride is adhered to the lower surface, a ceiling plate made of another material may be used. Further, the folding plate may be fixed with a sword point bolt or the like.

Therefore, the support arm 3 is provided at the lower portion of the tight frame 1 so that the rafter members 14, 14 which receive the edge of the ceiling plate 15 can be supported. The ceiling boards 15, 15 can be attached. Moreover, in the construction, the rafter member 1
Since the positions of the beams 4 and 14 on the beam member 10 are set by positioning the tight frame 1, workability is improved.

In the above embodiment, one strip-shaped support arm 3 is fixed, but separate support arms 22, 22 can be turned up and down like a tight frame 21 shown in FIG. In this case, the angles of the support arms 22 can be adjusted according to the inclination of the folding plate 16. The tight frame 31 shown in FIG.
The support arms 32, 32 may be integrally formed as shown in FIG. In each of FIGS. 4 and 5, the height of the step 23a at the intermediate portion of the main body 23 and the thickness of the support arms 22, 22 are adjusted so that the line connecting the projecting support arms 22, 22, 32, 32 is straight. The support arms 32, 3
2 is provided with an appropriate step 32a.

Further, the tight frame 4 shown in FIG.
1, the support arms 42, 42 are integrally formed, and no step is provided in the support arms 42, 42 and the intermediate portion of the main body 43, and the ribs 43a, 43a provided on the left and right portions of the main body 43 reinforce the main body 43. May be performed. Note that FIG.
Although the support arms 32 and 42 in FIG. 6 protrude in the horizontal direction, they may be inclined in accordance with the inclination of the folded plate 16.
