DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tight frame used for attaching a folded roof to a purlin or a beam, for example.

[0002]

2. Description of the Related Art Conventionally, as this kind of tight frame, a plurality of ridges corresponding to the bent shape of a folded roof are continuously provided in a longitudinal direction, and a male bolt called a sword-point bolt is provided at the top of each ridge. It is known that a screw is protruded.

When mounting a folded roof using such a tight frame, first, a tight frame is fixed to a beam or the like, and a male screw is mounted while the peaks of the folded roof and the tight frame overlap each other. Place the folded roof on a tight frame while punching the folded roof with the sharp part provided at the tip of the. Then, a female screw having a water-stopping member is sequentially screwed into a male screw projecting upward from the folded roof and fastened to fix the folded roof on each tight frame.

[0004]

However, in the above-mentioned mounting method, in order to punch a folded roof with a male screw,
In addition to the need for the operator to hit the top of the peak of the folded roof placed in an unstable state on the sharp part of the male screw with a hammer, etc., and after that work, as described above, A female screw has to be screwed into the male screw, and there is a problem that the workability is complicated.

In view of the above, a method has been considered in which the folded roof is fastened and fixed to the tight frame by a tapping screw without providing a male screw on the tight frame. In other words, by screwing a tapping screw from the folded roof side to the peak of the tight frame so as to penetrate the folded roof, there is no need to previously drill a prepared hole in the folded roof or the tight frame, and The folded roof can be fixed by one operation of screwing in the tapping screw.

However, since the tight frame is hidden under the folded roof and the worker cannot see the tight frame, it is determined where the tight frame is located in the longitudinal direction of the mountain of the folded roof. However, there is a problem that the screw cannot be accurately screwed into a desired screwing position.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and by enabling the position of a tight frame hidden under a folded roof to be easily confirmed, fastening of a tapping screw or the like from the folded roof side. An object of the present invention is to provide a tight frame into which a screw can be accurately screwed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a tight frame according to the present invention has a crest portion 2 corresponding to the bent shape of a folded roof 1. The folded roof 1 is placed so as to overlap with the crest portion 2, and a fastening screw 3 such as a tapping screw for fastening while drilling is screwed into the folded roof 1 from the folded roof 1 side. In the tight frame to be attached, when the fastening screw 3 is screwed in, the rising portion 6 of the peak portion 2 has a convex shape or a convex shape so that an operator can confirm the position of the tight frame hidden below the folded roof 1. It is characterized in that a concave marking part 7 is formed.

When a tight frame having the above structure is used, for example, if the folded roof 1 is placed on a tight frame in which a raised marking portion 7 is formed on the rising portion 6, the folded frame 1 is placed above the marking portion 7. Is pressed from the back side by the marking portion 7 and is deformed upwardly in a convex shape. Therefore, the worker can grasp the position of the hidden tight frame by the deformed folded roof portion 1 and screw the fastening screw 3 with the deformed portion by the marking portion 7 as a mark. The roof 1 can be mounted on a tight frame.

In a tight frame having a concave marking portion 7 formed thereon, when an operator presses the surface of the placed folding roof 1 downward, the folding plate located above the marking portion 7 is pressed. Since the roof 1 is depressed according to the shape of the marking portion 7, the position of the tight frame can be confirmed thereby.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a tight frame according to the present invention will be described with reference to FIGS.
A crest 2 corresponding to the bent shape of the folded roof 1 is formed, and the folded roof 1 is placed so as to overlap with the crest 2, and a fastening screw 3 such as a tapping screw for fastening while drilling is provided.
The tight frame to which the folded roof 1 is attached by screwing from the folded roof 1 side will be described.

The tight frame according to the present embodiment is shown in FIG.
As shown in FIG. 3, three thin ridges 2 are formed in a row in the longitudinal direction of the tight frame by bending a thin metal plate, and the ridges 2 and the bottom 4 are formed.
Each crest portion 2 includes a flat top portion 5 and a rising portion 6 that is located on both sides of the top portion 5 and that is formed in a downwardly opening tapered shape.

Each of the rising portions 6 is provided with a convex so that an operator can confirm the position of the tight frame hidden under the folded roof 1 as shown in FIG. The marking part 7 is formed. Specifically, the convex marking portions 7 are formed along the longitudinal direction of the tight frame, and each marking portion 7 is formed so as to be substantially straight, and as shown in FIG. It is formed so as to protrude toward the surface side. The bottom 4 is provided with a mounting hole 8 for fixing the tight frame to a beam or the like with screws or the like.

Next, an example of use of the tight frame will be described. First, a plurality of tight frames are fixed to a beam or the like with a predetermined interval. In addition to the stop, there is a method of fixing the bottom 4 to a beam or the like by welding.

After fixing to a beam or the like, as shown in FIG.
The folded roof 1 is placed on the tight frame such that the peak 9 and the bottom 10 of the folded roof 1 overlap with the peak 2 and the bottom 4 of the tight frame, respectively.

Next, the placed folded roof 1 is attached to each tight frame with a fastening screw 3. At this time,
Since the folded roof 1 and the tight frame overlap each other, it is possible to distinguish between the peak portion 2 and the bottom portion 4 of the tight frame, but the tight frame is hidden below the folded roof 1 so that it is tight from the worker side (upper side). The frame itself cannot be checked visually. Therefore, as shown in FIG. 4, when the screwing position R of the fastening screw 3 is the top 5 of the peak 2, the tight position of the peak 9 of the folded roof 1 in the longitudinal direction (the direction of the arrow Q in FIG. 3). It is necessary to determine whether the top 5 of the frame is located.

However, since the raised portion 6 of the tight frame according to the present embodiment is formed with the convex marking portion 7, as shown in FIG. 3 and FIG.
The rising portion 11 is pressed from the back side by the marking portion 7 and is deformed in a convex shape so as to rise upward. And since the marking part 7 is formed in each rising part 6 and is provided substantially straight along the longitudinal direction of the tight frame, each deformed part 12 of the folded roof 1 is also substantially straight, Screwing position R using the deformed portion 12 as a mark
Can be specified, the fastening screw 3 can be securely inserted, and the folded roof 1 can be attached accurately and quickly.
If the folded roof 1 is not thin but relatively thick,
The rising portion 11 of the folded roof 1 may be hit with a hammer or the like.

In this embodiment, a tapping screw is used as the fastening screw 3.
As shown in FIG. 4, the tip portion 13 has a drill shape,
Thereby, it can be perforated in the folded roof 1 and the tight frame, and can be screwed and fixed by the screw portion 14 on the root side. In addition, between the head 15 of the tapping screw and the folded roof 1, an inverted dish-shaped washer 16 and a ring-shaped water blocking member 17 made of felt that has absorbed coal tar are interposed. The washer 16 and the water-stopping member 17 are integrally screwed into the tapping screw using a screw inserted and fixed in advance.

In the above configuration, the convex marking portion 7 is provided.
The concave marking portion 7 is formed as shown in FIG.
May be formed. In this case, the deformation part 12 as described above is not formed only by placing the folded roof 1,
When the worker presses the surface of the folded roof 1 downward, the rising portion 11 of the folded roof 1 is easily elastically deformed according to the shape of the marking portion 7 as shown by the two-dot broken line in FIG. The screwing position R can be similarly specified using the position as a mark. When the folded roof 1 is relatively thick, a dent can be formed by hitting with a hammer or the like. By providing the marking portion 7 along the longitudinal direction as shown in FIGS. 1 and 5, the marking portion 7 also has a function as a rib, and the advantage is large in terms of strength.

The position and the shape of the marking portion 7 are not particularly limited. In addition to the above-described structure, for example, as shown in FIG. The part 7 may be formed. In any case, the top 5
Is preferably provided with a marking portion 7 other than the top portion 5, so that the marking portion 7 does not hinder the screwing of the fastening screw 3 into the top portion 5. Since the adhesion to the folded roof 1 is further enhanced,
Installation becomes easier.

In addition, the shape and number of the peaks 2 are not particularly limited, and a pilot hole for inserting a fastening screw may be formed in the top 5.

[0022]

As described above, even if the tight frame cannot be visually confirmed, its position can be easily confirmed by the marking portion formed on the rising portion, so that the fastening screw can be accurately inserted from the folded roof side. In addition, the mounting operation can be performed extremely simply and quickly.

Also, since the top is provided not at the top of the peak but at the rising portion, the tight frame and the top of the folded roof more closely adhere to each other than when provided at the top, and the fastening screw is screwed to the top. In the case of insertion, there is also an effect that the fastening can be securely performed without disturbing the presence of the marking portion during the screwing operation.
