Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention is used to form a roof or an outer wall.

[0002]

[Prior art]

 To form a roof or outer wall using a folded plate, the folded plate was applied to a supporting metal fitting such as a tight frame fixed to the base material, and fixed with a bolt or a nut. However, a tightening machine is indispensable for tightening the food, and if it takes time to raise it to a high place, it must be said that the work is time-consuming. Further, when using the bolts and nuts, it is necessary to individually screw them, and in this case as well, it was troublesome. In addition, the bolts and nuts are exposed on the outer surface, so the reduction in design value was also a problem.

Therefore, for example, as disclosed in Japanese Patent Publication No. 7-1169797, a fixing structure has been devised which does not use a fastening or a bolt nut for fixing a folding plate. In this structure, both side edges of the folded plate are formed so as to correspond to the half shape in the left-right direction of the mountain-shaped tight frame, and both side edges are arranged between the tight frames while being locked to the tight frame. At the ends of adjacent folded plates, long caps for fixing both folded plates to the tight frame are fitted and fixed.

In this folded plate fixing structure, it is not necessary to fix the folded plates sequentially from one side, and there is an advantage that the work can be appropriately performed according to the situation, but since the cap is required, the two-stage fixing work is performed. However, the number of parts was increased and management was troublesome.

[0005]

[Problems to be solved and means therefor]

 Therefore, this invention proposes a folding plate fixing structure, a tit frame, and a folding plate that can be fixed very simply by a true one-touch method and that does not impair aesthetics. The challenge is to provide.

In the structure of the folded plate fixing structure for that purpose, the tight frame is arranged on the base material, and the folded plate is fixed to the tight frame in order from one direction while overlapping the side edges. With a folded plate fixing structure, the tight frame is bent into a divergent, substantially mountain-like shape using a strip-shaped metal plate, and the top is formed with locking parts that project to the left and right sides. A receiving portion for receiving the lower surface of the locking convex portion of the folding plate is formed at a position spaced apart from the above portion by a predetermined distance, and the folding plate is fitted at one side edge thereof to the tit frame. A first locking part having two locking projections which are positioned in a locking space between the locking part and the receiving part when worn, and which are locked to the locking part and prevented from falling off. The first locking part of the adjacent folded plate fitted to the tight frame above the other side edge. And a second locking portion having a locking convex portion at the tip thereof which covers the first locking portion and locks with one locking convex portion on the width direction intermediate side of the folding plate in the first locking portion. It is a feature.

The tight frame is formed by bending a strip-shaped metal plate so that it rises inward from both open legs and forms a generally chevron shape that spreads toward the end, and is fitted from above. Is a tight frame in which locking parts for locking the folding plate are provided on both left and right sides, and the locking parts are formed on the top part, and below the locking parts, at predetermined positions. It is characterized in that the receiving portion for receiving the lower surface of the locking convex portion of the folding plate is formed by projecting to the left and right sides.

[0008] Furthermore, the folding plate is a folding plate in which the side edge members are sequentially fitted and fixed to the tight frame arranged on the base material while being overlapped with each other. On one side edge that is on the side, in order to fit into a tight frame that has a substantially mountain shape as a whole and has locking parts protruding to the left and right sides at the top, there are locking projections on both the left and right inner side surfaces that form a substantially mountain shape. The first locking portion having the first locking portion is formed, and the other side edge that is on the upper side at the time of stacking covers the first locking portion from above, and the width of the folding plate of the two locking projections. It is characterized in that a second locking portion having a locking projection that locks to one locking projection on the middle side in the direction is formed.

[0009]

[Action and effect]

 According to each of the above-described configurations, when fixing the folded plate, the tight frame is first fixed on the base material, and then the other side edge having the second locking portion is attached to the tight frame. One side edge having the first locking portion is fitted and fixed to the tight frame while being locked to the locking portion. The locking of the second locking portion is performed by locking one locking convex portion forming the second locking portion with one of the two locking convex portions forming the first locking portion from the outside. The first locking portion is locked by the two locking projections being locked below the locking portion of the tight frame. Further, since the lower surface of the first locking portion is received by the receiving portion of the tight frame, it can be supported even if a load is applied.

As described above, since the folding plate can be fixed only by sequentially fitting it from one side, a true one-touch without using other members such as a conventional cap member. It can be done with a formula very easily, and the workability can be further improved.

Further, since the bolts and nuts are not exposed in the fixed state, it is possible to prevent the appearance from being impaired, and if the tight frame is formed from a single metal plate, the tight frame can be formed. The production of can be done only by simple press working, and the number of parts can be suppressed as much as possible.

Further, since the tight frame is formed with the receiving portion that receives the lower surface of each locking projection of the first locking portion of the folding plate, the load can be supported and the folding plate can be fixed with high strength. You can get the structure.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a folded plate fixing structure. In this folded plate fixing structure, a tight frame 2 is arranged on a base material 1, and a folded plate 3 is placed on the tight frame 2 in order from one direction. , The side edges were overlapped with each other and fixed with a one-touch method.

First, the structure of the tight frame 2 will be described. The tight frame 2 is made of a strip-shaped metal plate and is bent into a divergent mountain-like shape. At the top, locking portions 4 and 4 projecting to the left and right sides are formed. A receiving portion 7 for receiving the lower surface of the locking convex portion 6 of the folding plate 3 is formed at a position below the predetermined distance (locking space 5).

More specifically, as shown in FIG. 2, the tight frame 2 is composed of a main body 8 and a plate member 9, and the main body 8 is opened from a grounding portion 10 joined to the base material 1. The legs 11 and 11 are formed, and the legs 11 are raised upward inward, and are bent horizontally inward at an intermediate position in the height direction to form the above-mentioned receiving portion 7, and the receiving portion 7 having a predetermined width is formed. After the tip is raised again inward and upward, the horizontal top surface 12 is formed. A widthwise intermediate portion extending from one leg portion 111 to the receiving portion 7, the top surface 12, and the other leg portion 11 and both widthwise end portions of the top surface 12 are reinforced with downward convex portions. Forming ribs 13 and 14 for use.

The plate-shaped member 9 is for forming the locking portion 4 described above, and is formed by using another band-shaped (rectangular-shaped) metal plate. The plate-shaped member 9 has an intermediate portion 15 in the left-right direction formed in a planar shape and a square hole 16 formed in the center. The left and right edges are formed with the above-mentioned engaging portions 4 which are inclined downwards like a claw and then bent downwards. Further, when the lower surface of the plate-shaped member 9 is brought into surface contact with the top surface 12 of the main body 8 on any one of the front and rear sides of the above-mentioned intermediate portion 15, the positional relationship between the two members can be kept constant. Therefore, the anti-rotation piece 17 is provided vertically. The engaging portion 4 may be formed by raising a part of the main body 8 having the above-described shape, or may be integrally formed by double-folding, but it is better to form it separately. It is easy to make.

The plate-shaped member 9 is placed on the main body 8 by means of a root angle bolt 18, a washer 19, a spring washer 20, and a nut 21. For this reason, a through hole 22 through which the root angle bolt 18 can be inserted is formed at an intermediate position in the width direction on the top surface 12 of the main body 8. FIG. 3 shows a mounted state. Placement may be done by rivets or welding in addition to bolts and nuts. Further, in the drawings, the tight frame is drawn as a double type, but it may be a single type or a triple type.

Next, the structure of the folded plate will be described. As shown in FIG. 4, the folded plate 3 is formed in a shape corresponding to the ups and downs of the tight frame, and one side edge which is the lower side at the time of stacking has a substantially chevron shape as a whole, and the above-mentioned locking portion 4, In order to fit into the tight frame 2 having 4, the first locking portions 23 having the locking projections 6 and 6 are formed on the left and right inner side surfaces which are substantially chevron-shaped, and are formed on the other side edge which is on the upper side at the time of stacking Covers the first locking portion 23 from above, and of the two locking projections 6 and 6 of the first locking portion 23, one locking projection on the widthwise intermediate side of the folding plate 3.
