Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tight frame suitable for mounting a ceiling plate on the upper surface side of a beam.

[0002]

[Prior art]

 A tight frame is used to cover an uneven plate on a beam, and is usually fixed at a position on the beam that corresponds to the convex peaks, and a hanger or sword bolt is used. I am printing an edition.

[0003]

[Problems to be solved by the device]

 However, it may be necessary to attach a ceiling plate to the upper surface of the beam for heat insulation and other purposes. In this case, the ceiling plate should be installed between the tight frames lined up at a predetermined interval on the same beam, but it is possible to fix the ceiling plate between the beams lined up in the slope direction of the roof. I cannot do it, and the installation is not stable. Therefore, it is conceivable to hang a long rafter between the beams and attach a ceiling plate between the rafters.

However, since both the rafter and the tight frame are fixed on the beam member, the tight frame becomes an obstacle, and there is a problem in that the ceiling plate cannot be properly attached. Therefore, the present invention aims to provide a tight frame to which a ceiling plate can be attached.

[0005]

[Means for Solving the Problems]

 A means for solving the above-mentioned problem will be described with reference to FIG. 3 of an embodiment. The structure is a tight frame 1 in which a beam member 10 is fixed and folding plates 16 and 16 are roofed upward. In order to mount the ceiling plates 15, 15 on the upper surface side of the beam member 10, the support arm 3 for supporting the rafter members 14, 14 for receiving the edges of the ceiling plates 15, 15 is provided in the tight frame 1 main body 2 It is characterized by a tight frame 1 formed in an appropriate length in the lower part of the plate along the gradient direction of the plate.

[0006]

[Action]

 That is, according to the above configuration, when fixing the tight frame on the beam member, the rafter member may be supported by the supporting arm of the tit frame. The ceiling board can be attached to this rafter member.

[0007]

[Effect of device]

 As a result of the above, according to the present invention, since the supporting arm is provided at the lower part of the tight frame so that the rafter member for receiving the edge portion of the ceiling plate can be supported, the ceiling is stable and the appearance is good, and the ceiling is in a good condition. You can install the board.

Moreover, in the construction, since the position of the rafter member on the beam is set by the positioning of the tight frame, the workability is improved.

【Example】

 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 is composed of 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 symmetrical with respect to the left and right, and the receiving plates 4 and 4 and the supporting plates 5 and 5 are formed on the upper end and the lower end at predetermined intervals, respectively. An insertion hole 6 for inserting the above-mentioned support arm 3 is formed at an intermediate position in the left-right direction in the lower portion, and burring holes 7, 7 for fixing the support arm 3 are formed on both sides of the insertion hole 6. And square holes 8 for attaching the suspension are formed in the upper part.

Such a metal substrate 2a is either mountain-folded or valley-folded along the broken line and the alternate long and short dash line shown in the figure. At the intermediate position between the left and right, the metal base plate 2a and the support arm 3 are displaced by a thickness corresponding to the thickness of the support arm 3 so that the mountain-folded side comes to the front so that the support arm 3 can be inserted into the insertion hole 6. To

The support arm 3 is formed in a strip shape having an appropriate length as shown in FIG. 1, and is inserted into the insertion hole 6 of the main body 2 so that the protrusions 3a, 3a have the same length. When this is done, the burring holes 9, 9 are also formed at the positions corresponding to the burring holes 7, 7.

The main body 2 and the support arm 3 may be fixed by a suitable method, not by burring as described above, but by welding or by bolts and nuts. As shown in FIG. 3, the tight frame 1 configured as described above fixes the support plates 5 and 5 at the lower end to predetermined positions on the beam member 10 with the support arm 3 oriented in the slope direction of the roof. The suspension 11 is fixed to one of the square holes 8 and 8 formed in the upper part with bolt nuts 12 and 13. Then, the rafter members 14, 14 corresponding to the length between the beam members 10 are supported and attached to the projecting portions 3 a, 3 a of the support arm 3. The rafter members 14, 14 have a substantially inverted V-shaped cross section, have an insertion groove 14a in the middle portion, and have receiving portions 14b, 14b protruding in the left-right direction at the lower end.

The ceiling plates 15 and 15 are attached by supporting the edges of the receiving portions 14b and 14b of the rafter members 14 and 14 which are supported by the projecting portions 3a and 3a of the support arm 3 and by supporting the tight frame 1 It is carried out by pressing from the top with the valley portions 16a, 16a of the folding plates 16, 16 fixed to the suspension 11 of. The ceiling plates 15 and 15 described above are strip-shaped members having a width dimension corresponding to the interval between the rafter members 14 and 14, and the addition in the slope direction of the roof can be performed, for example, at the beam member 10 position. The ceiling plates 15 and 15 shown in the figure are made by compressing glass wool 15a and affixing a vinyl chloride decorative sheet 15b on the lower surface, but they may be ceiling plates made of other materials. In addition, the stencil bolts may be used to fix the folded plate.

Therefore, since the supporting arm 3 is provided below the tight frame 1 so that the rafter members 14, 14 for receiving the edge of the ceiling plate 15 can be supported, it is stable and has a good appearance. The ceiling plates 15 and 15 can be attached with. Moreover, in the construction, the positions of the rafter members 14, 14 on the beam member 10 are set by the positioning of the tight frame 1, so that the workability is improved.

In the previous embodiment, one strip-shaped support arm 3 is fixed, but separate support arms 22 and 22 can be rotated up and down like a tight frame 21 shown in FIG. However, in this case, the angles of the support arms 22 and 22 can be adjusted in accordance with the inclination of the folding plate 16. Further, like the tight frame 31 shown in FIG. 5, the support arms 32, 32 may be integrally formed. In both cases of FIGS. 4 and 5, the thickness of the step 23a in the middle part of the main body 23 and the thickness of the support arms 22, 22 are adjusted so that the line connecting the protruding support arms 22, 22, 32, 32 is straight. And adjusting the support arms 32, 32 with appropriate steps 32a, 32a.

Further, like the tight frame 41 shown in FIG. 6, the support arms 42, 42 are integrally formed, and no step is provided in the support arms 42, 42 or in the intermediate portion of the main body 43. The main body 43 may be reinforced by ribs 43a, 43a provided on the portions. Although the support arms 32 and 42 in FIGS. 5 and 6 are projected in the horizontal direction, they may be obliquely provided so as to correspond to the inclination of the folding plate 16.
