[0005]

[Means for Solving the Problems]

 A means for solving the above-mentioned problem will be described with reference to FIG. 1 of an embodiment. The structure is a tight frame 1 formed by bending a single metal plate punched into a predetermined shape. Notches 5 and 5 into which the ends of the joiner are inserted are formed in an intermediate portion 4 between the folded plate fixing portion 2 formed in the upper portion and the leg portion 3 formed in the lower portion. It is characterized in that the lower part is a tight frame 1 with the support parts 6 and 6 of the joiner.

In order to make the joiner fit well and to increase the strength of the tight frame 1, the shape of the cutouts 5 and 5 lower part 5a is a straight line whose height becomes lower toward the outer end side. Alternatively, a curved inclined shape may be set.

Further, in order to strengthen the fixed state of the tight frame 1 to the beam member, the lower end surfaces of the support portions 6 and 6 may be set flush with the lower surface of the leg portion.

[0008]

[Action]

 That is, according to the above configuration, when manufacturing the tight frame, it is sufficient to bend a single metal plate punched into a predetermined shape. To use it, the lower leg is fixed to the beam by welding, etc., and the joiner end is inserted into the notch formed in the middle part to support the horizontal position of the joiner by the support part. Then, place the ceiling boards on both sides of the joiner. Then, the folded plate roof may be fixed to the upper fixed portion of the folded plate through a hanging member or the like.

[0009]

[Effect of device]

 As a result of the above, the effect achieved by the present invention will be described below.

In the tight frame according to the first aspect, the number of parts required for manufacturing is only one and the material cost, management cost and the like can be reduced, so that the tight frame can be manufactured at low cost. In addition, it does not require bolting work as in the past, so it is extremely easy to manufacture.

In the tight frame according to claim 2, since the shape of the lower portion of the notch is set to be an inclined shape in which the height becomes lower toward the outer end side, unlike the case where the shape is set horizontally, the length and height of the joiner Even if there is some error in the size, the error can be absorbed, and it is possible to obtain a favorable support state that is well-contained.

Further, since the base of the supporting portion is not at a right angle, it is possible to prevent the load from being concentrated on only the base, so that the strength of the tight frame can be increased and maintained.

In the tight frame of claim 3, since the lower end surface of the supporting portion, which is different in directionality from the leg portion, also contacts the beam member, the leg portion is fixed to the beam member at the same time. As compared with the case where only the legs are fixed, the tight frame can be firmly fixed to the beam member.

Further, when fixing the tight frame, the positioning can be performed easily and accurately by using the support portion as a reference.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. (First Embodiment) FIG. 1 is a perspective view showing a tight frame 1. As shown in FIG. 1, the tight frame 1 has a folding plate fixing portion 2 at an upper portion and leg portions 3 at a lower portion. The notches 5 and 5 are formed in the middle portion 4 between them. The lower portions of the cutout portions 5 and 5 are used as support portions 6 and 6 for supporting the joint A (see FIG. 3).

This tight frame is formed by bending a single metal plate 1a punched into a shape as shown in FIG. That is, the shape is symmetrical to the left and right, and in the upper part of the main body part 7, the receiving plates 8 and 8 forming the folding plate fixing part 2 and the square holes 9 and 9 for fixing the suspension are formed, and in the lower part. The fixing plates 10 and 10 and the connecting plates 11 and 11 that form the leg portion 3 are formed.

The receiving plates 8 and 8 have a horizontal portion 8a bent at a right angle to the main body and an inclined portion 8b bent downward from the horizontal portion 8a by a predetermined angle. The left and right receiving plates 8 and 8 are bent in opposite directions (front side or the other side).

The fixed plates 10 and 10 have a rectangular shape having an appropriate area, and are connected to the connecting plates 11 and 11 on one side. It is connected to the inside of the support portions 6 and 6 on one side with different directions. Then, the fixing plates 10 and 10 and the connecting plates 11 and 11 are also bent in the left and right directions opposite to each other (front side or the other side).

The side connecting the above-mentioned connecting plates 11 and 11 is set at the same position as the inside edge of the notches 5 and 5 or inside thereof. When the above-mentioned bending is performed, the dimensions are set so that the lower surfaces of the fixed plates 10 and 10 and the lower end surfaces of the support portions 6 and 6 are flush with each other.

The above-mentioned notches 5 and 5 are for making the metal plate 1a into a slim shape in which the middle portion 4 is constricted, and in particular, the shape of the lower portion 5a is such that the height becomes lower toward the outer end side. It is set in a slanted shape. At this time, the height of the roots of the supporting portions 6 and 6 formed by forming the notches 5 and 5 is set so as to correspond to the height of the joiner A. The shape of the cutouts 5, 5 lower part 5a may be a linear inclination.

In the figure, the broken lines 12 ... and the alternate long and short dash lines 13 ... Are lines for indicating the positions where they are bent in opposite directions, and are either mountain folds or valley folds.

In the manufacture of the tight frame 1, the metal plate 1a punched into the above-described shape is bent along the lines 12 ..., 13 ... As described above, and as shown in FIG. The parts 2 are staggered, and a step 14 having an appropriate height is formed in the middle part in the width direction. At this time, the folding plate fixing portion 2, the lower leg portion 3, and the intermediate portion 4 are formed with two reinforcing ribs 15 and 15 in different projecting directions along the height direction. Strengthen the shape. Further, reinforcing ribs 16 and 16 are also formed at right angles between the main body 7 and the horizontal portions 8a and 8a to strengthen the shape.

The cross-sectional shape of the above-described joiner A has receiving portions A1 and A1 for mounting ceiling plates B and B on both side edges of the lower portion, and a groove having a predetermined height in an intermediate portion in the width direction. It has a shape having A2, and its length corresponds to the width between the beam members B (see FIG. 3).

The tight frame 1 thus configured is used as shown in FIG. First, the lower leg portion 3 is fixed to a predetermined position on the beam C by welding. This welding may be performed not only on the fixing plates 10 and 10 but also on the lower ends of the supporting portions 6 and 6.

Then, the ends of the groove A2 in the intermediate portion of the joiner A are inserted into the notches 5 and 5 formed in the intermediate portion 4, and the supporting portions 6 and 6 support the horizontal position of the joiner A. The joining of the joiner A into the notch may be performed from the top by inserting one end and then drawing an arc as shown by a virtual line at the other end.

After that, the ceiling boards B, B are placed on the receiving parts A1, A1 of the joiner A, and then the folding plate roofs E, E are fixed via the suspenders D attached to the square holes 9. The ceiling boards B, B are pressed by the valley portions of the folded plate roofs E, E.

Therefore, since the tight frame 1 can be formed by only one component (the metal plate 1a), the material cost, management cost and the like can be reduced and the tight frame 1 can be manufactured at low cost. In addition, it does not require bolting work as in the past, so it is extremely easy to manufacture.

Moreover, since the shape of the lower portions 5a of the cutouts 5 and 5 is set to be an inclined shape in which the height becomes lower toward the outer end side, even if there is some error in the length or height of the joiner A, the error will be eliminated. It is possible to absorb, and it is possible to obtain a well-supported condition with good fit.

Further, since the roots of the support portions 6 and 6 are not at right angles, it is possible to prevent the load from being concentrated on only the root portions, so that the strength of the tight frame 1 can be increased and maintained.

Further, when welding on the beam C, not only the fixing plates 10 but also the lower end surfaces of the supporting portions 6 can be welded, so that the tight frame 1 is firmly fixed to the beam C. You can also

Further, when fixing the tight frame 1, the positioning can be performed easily and accurately by using the supporting portions 6 and 6 as a reference.

(Other Embodiments) FIG. 4 is a perspective view showing a tight frame 1 according to another embodiment. As shown in FIG. 4, the lower leg portion 3 is composed of only the fixing plates 10 and 10. You can do it. Also in this case, it is preferable to set the lower surfaces of the fixing plates 10 and 10 and the lower end surfaces of the supporting portions 6 and 6 so that they are flush with each other because the fixed state becomes firm and the positioning is easy. Not good. Reference numeral 17 in the drawing is a reinforcing rib.
