b, a third locking portion 33 that locks to the first locking portion 31 or the second locking portion 32, and a fourth locking portion that locks to the third fixing piece 12 above the tight frame 3. It is characterized by a folded-plate roof fixing structure in which the portion 34 is formed.

A tight frame body 6 fixed to the base material 2 and a fixing metal 9 mounted and fixed on the tight frame main body 6 are provided. One side of the fixing metal 9 has a folded plate roof 1. A first fixing piece 10 and a second fixing piece 11 for respectively locking two places of a first locking part 31 and a second locking part 32 formed above and below one side edge 1a are formed vertically. On the other side of the fixing bracket 9, upper and lower 2 formed on the other side edge 1b of the folded-plate roof 1.
The third fixing piece 12 for locking the lower fourth locking part 34 of the three locking parts 33 and 34 is formed, and the fixing metal 9 is connected to the first fixing piece 10 and the second fixing piece. Eleventh and third
The tight frame 3 is formed by joining a first metal member 13 having any two fixing pieces 10 and 12 of the fixing pieces 12 and a second metal member 14 having another one fixing piece 11. It is characterized by the following.

Further, it is composed of a tight frame main body 6 fixed to the base material 2 and a fixing metal 9 mounted and fixed on the upper portion of the tight frame main body 6. A first fixing piece 10 and a second fixing piece 11 for respectively locking two places of a first locking part 31 and a second locking part 32 formed above and below one side edge 1a are formed vertically. On the other side of the fixing bracket 9, the lower fourth locking portion 34 of the upper and lower two locking portions 33, 34 formed on the other side edge 1b of the folded plate roof 1.
And a tight frame 3 formed by pressing a single metal plate.

Referring to FIG. 11 of the embodiment, a first locking portion and a second locking portion formed above and below one side edge of a folded plate roof are provided on one side of the upper portion of the tight frame body. The first fixed piece 10 and the second fixed piece 11 for locking the two places are vertically formed, and the other side of the upper part of the tight frame main body is formed on the other side edge of the folded plate roof. Third fixing piece 1 for locking the lower fourth locking part of the two locking parts
2, and the tight frame 3 is configured such that the first fixing piece or the third fixing piece is formed integrally with at least the tight frame main body.

Referring to FIG. 1 and FIG. 13 of the embodiment, in the above-mentioned folded plate roof fixing structure, both ends are required to increase waterproofness, improve design feeling, and increase strength. A long cap 4 having elastic locking portions 41 and 42 on its edge is provided, and the elastic locking portion 41 on one side edge of the cap 4 is provided.
Of the folded plate roof 1 fixed to the tight frame 3
The elastic member 42 is formed on the tight frame 3 so that it can be locked to the locking portion 31, the second locking portion 32, or the third locking portion 33, and the other side edge of the cap 4 is elastically locked. The fourth locking portion 34 of the folded plate roof 1 or the fifth locking portion 39 formed at a position along the vertical direction of the fourth locking portion may be formed so as to be lockable.

[0012]

According to the structure of the first aspect, one side edge of the folded-plate roof is fixed at two upper and lower portions of the first fixed piece and the second fixed piece of the tight frame, and the negative pressure acts on the one side edge. Even when a force is applied in a direction in which the first locking portion and the second locking portion come off,
The deformed folded-plate roof has a different curvature depending on the part, and the locking of both does not come off at the same time. Further, even if one of the members receives a greater force in the direction in which it comes off, the other applies a force in a direction in which it does not come off against this force. In addition, the other side edge of the folded plate roof is also strongly locked at two places, the first locking portion or the second locking portion, and the third fixing piece.

According to the second to fourth aspects of the present invention, the first fixing piece and the second fixing piece respectively lock one side edge of the folded plate roof. Therefore, for example, even when a negative pressure is applied and a force is applied in a direction in which the first locking portion and the second locking portion of the folded-plate roof are disengaged, the deformed folded-plate roof has a different curvature ratio depending on a portion. However, the locking of both does not come off at the same time. Also, even if one of the members receives a greater force in the direction in which it comes off, the other applies a force in a direction in which it does not come off against this force. The other side edge of the folded plate roof is also locked at the position corresponding to the first fixing piece or the second fixing piece and the third fixing piece.

According to the fifth aspect of the present invention, the long cap covering the overlapped portion of the two folded-plate roofs enhances the fixing state to the tight frame, improves the waterproofness, and improves the design feeling. .

[0015]

As a result of the above, according to the folded plate roof fixing structure of the present invention, both the one side edge and the other side edge of the folded plate roof are locked at two places, so that the locking force is increased, A strong fixed state can be obtained. In particular, since one side edge of the folded plate roof is locked at the upper and lower two places, even if a negative pressure acts and the folded plate roof is curved, the two places are not simultaneously unlocked. Then, even if a higher force in the detaching direction acts on one of the locking portions, the other locking portion suppresses the force, so that the locking force is extremely high. As one side edge of the folded plate roof is firmly fixed in this way, the other side edge of the folded plate roof, which is partially overlapped with this and locked, naturally becomes strong, as a whole A good fixed state is obtained.

Moreover, the operation of obtaining such a firmly fixed state is very easy, since it is only necessary to fix the tight frame on the base material and then sequentially fit the folded-plate roofs.

Further, since one side edge of the folded plate roof is locked at two places, the shape can be changed as compared with the conventional folded plate roof fixing structure, and a novel design feeling can be provided. .

[0018] According to the tight frame of the second, third and fourth aspects, one side edge and the other side edge of the folded plate roof are both set to two.
Since the parts are locked, the locking force can be increased and a strong fixed state can be obtained. In particular, since the upper and lower portions are locked at one side edge of the folded-plate roof, even if the folded-plate roof is curved due to a negative pressure, the two portions are not simultaneously released. Even if a force in the higher release direction acts on one of the locking parts,
Since this is suppressed at the other locking portion, the locking holding force is extremely high. As one side edge of the folded plate roof is fixed firmly in this way, the fixed state of the other side edge of the folded plate roof, which is partially overlapped with this and locked, can of course be firmly fixed, as a whole A good fixed state is obtained.

Further, since the first fixed piece, the second fixed piece, and the third fixed piece are formed on the tight frame, a novel design feeling can be obtained, which has never been achieved in the related art. A beautiful appearance can be imparted to the fixed state.

In particular, in the tight frame according to the second aspect, since the fixing bracket on the upper portion of the tight frame is composed of two members, for example, if the two members are fixed to the tight frame main body with bolts and nuts, the folding frame can be folded. Locking at two locations on one side edge of the flat roof can be easily performed without requiring excessive force. That is, the bolts and nuts may be loosened when the folded plate roof is locked, and the bolted nuts may be tightened after the folded plate roof is brought into a predetermined locked state without being deformed.

In addition, by making the corresponding surfaces of the two members constituting the fixing member into surface contact with each other to form a double structure, the strength can be improved without forming a special reinforcing structure.

In the tight frame according to the third aspect, since the fixing bracket on the upper portion of the tight frame is formed by one member, the number of parts can be reduced, and management and handling can be facilitated.

Further, in the tight frame of the fourth aspect, a first fixing piece and a second fixing piece are formed vertically on one side of the upper part of the tight frame main body, and a third fixing piece is formed on the other side of the upper part of the tight frame main body. Since the fixing piece is formed and the first fixing piece or the third fixing piece is integrally formed at least with the tight frame body, the shape of the member can be simplified, and the cost can be reduced and the management can be made. Can be facilitated.

According to the folded roof fixing structure of the fifth aspect, the long cap is fitted to the overlapping portion of one side edge of the folded roof and the other side edge of another folded roof adjacent thereto. It is possible to enhance the locking state of the folded plate roof with respect to the tight frame. At the same time, the waterproofness can be improved and the design feeling can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

(First Embodiment) FIG. 1 is a sectional view showing an example of a folded plate roof fixing structure. As shown in this figure, the folding plate roofs 1 and 1 are fixed to base materials such as beams and purlins. After fixing the tight frame 3 on the top 2, the folded plate roofs 1 and 1 and the cap 4
Are sequentially fitted.

First, the structure of the tight frame 3 will be described. The tight frame 3 is formed by pressing a metal plate. The tight frame 3 has fixed legs 5, 5 opened in the shape of an isosceles trapezoid fixed on the base material 2. And a fixing bracket 9 mounted and fixed by a bolt 7 and a nut 8 on the upper part of the upper part.

The fixing bracket 9 has, on one side thereof, a first fixing piece 10 and a second fixing piece 11 for locking two places of one side edge 1a of the folded-plate roof 1, and on the other side thereof. And a third fixing piece 12 that locks the inside of two places of the other side edge 1b of the folded-plate roof 1.

The fixing fitting 9 has a first fixing piece 10 having two fixing pieces, the first fixing piece 10 and the third fixing piece 12 described above.
It is composed of a metal member 13 and a second metal member 14 having the second fixing piece 11. As shown in FIG. 2, the first metal member 13 has a first fixing piece 10 projecting obliquely downward and outward on one side (left side in the figure) and a third fixing member on the other side (right side in the figure). The piece 12 protrudes obliquely downward and outward, and has a thin bottomed box-shaped seat portion 15 at an intermediate portion.

The seat portion 15 may have a flat seating surface. However, as shown in the drawing, a square step portion 15a projecting downward is formed, and the tight frame body 6 If the concave portion 6a into which the step portion 15a is fitted is formed on the upper surface, it becomes a detent when the fixing bracket 9 is placed and fixed on the tight frame main body 6, so that a correct positional relationship can be easily obtained. Good. In addition, the shape can be naturally reinforced.

A round hole 15b is formed in the center of the step portion 15a of the above-mentioned seat portion 15, and a square hole 6b is formed in the concave portion 6a of the tight frame body 6, and the above-mentioned bolt 7 (see FIG. 1)
Allows the insertion of Reinforcing ribs 16 are formed from both side surfaces of the seat 15 to the first fixing piece 10 and the third fixing piece 12.

The above-mentioned second fitting member 14 has a second fixing piece 11 projecting obliquely downward at one end (left side in the drawing) at the upper end.
And the other side (right side in the figure) at the lower end via the standing piece 17
Is formed at a right angle toward the support piece 18. A long hole 18a is formed in the support piece 18, and the first
The metal member 13 is movable in the left-right direction within the step 15a. This is so that the fitting of one side edge 1a of the folded plate roof 1 can be easily and easily performed as necessary, and when the one side edge 1a of the folded plate roof 1 (see FIG. 1) is fitted. Bolt 7
This is because if the nut 8 is loosened, the second fixing piece 11 can be moved to the other side (right side in the figure), and the bolt 7 and the nut 8 need only be tightened after obtaining a predetermined locking state. FIG.
Reference numeral 19 denotes a washer, and reference numeral 20 denotes a spring washer.

Further, reinforcing pieces 21 and 2 bent toward the other side (right side in the figure) are provided on both front and rear edges of the standing piece 17.
1 are integrally formed.

The support piece 18 may be a round hole 18b instead of the long hole 18a. If there is some margin, the bottle 7 and the nut 8 are loosened to change the posture of the second metal member 14 to the second fixing piece 1 as shown by the phantom line in FIG.
This is because the direction 1 can be changed to the direction in which the lock with the folded plate roof 1 is released.

The one side surface (left side in the figure) of the seat portion 15 of the first metal member 13 and the standing piece 17 of the second metal member 14
When the folded-plate roof 1 is locked so as to be in surface contact with each other, a double structure is obtained. For example, high strength can be obtained without taking special reinforcing means against deformation in the left-right direction.

In the above description, the first fitting member 13 and the second
Although the metal member 14 is made separable, it may be welded in advance and integrated. Similarly, the fixture 3 and the tight frame body 6 may be integrated in advance by welding.

The fixing pieces 10, 10 of the first metal member 13 and the second metal member 14 forming the fixing metal 9 are respectively provided.
The combination of 11 and 12 may be changed, for example, as shown in FIGS. The fixing fitting 9 in the example of FIG. 4 includes a first fitting member 13 having a second fixing piece 11 and a third fixing piece 12 and a second fitting member 14 having a first fixing piece 10. The members 13 and 14 are formed in a substantially U-shape as viewed from the front, are arranged on the left and right, and are fastened with bolts 7 and nuts 8. On the contrary, in the fixing fitting 9 of FIG. 5, the first fitting member 13 having the first fixing piece 10 and the second fixing piece 11
And a second fitting member 14 having a third fixing piece 12. Also in this case, each of the bracket members 13 and 14 is substantially U-shaped when viewed from the front.

In each case, each fitting member 1
Since the opposing surfaces 3 and 14 are in surface contact with each other, they exhibit high strength particularly against deformation in the left-right direction, and have a folded-plate roof 1, 1
Can be kept firmly.

It should be noted that the tight frame 3 shown in FIGS. 1, 2 and 3 is, of course, at least in the case of the tight frame 3 shown in FIGS. 4 and 5, as shown in FIG. If one of the metal members 13 and 14 is formed to be long from the roof ridge to the eaves, the metal member (14 in the drawing) located on the other side functions as an inner gutter, and does not leak rainwater that has entered. In this case, the effect is maximized if a packing (not shown) is interposed between the bolt and nut.

Next, the structure of the folded roofs 1 and 1 will be described. As shown in FIG. 1, the folded plate roofs 1, 1 have rising portions 1c, 1c at least on both side edges thereof, and one side edge 1a.
(A left side in FIG. 1 and a right side of the folded plate roof) include a first locking portion 31 that locks to the first fixing piece 10 of the tight frame 3 described above.
And a second locking portion 32 that locks to the second fixing piece 11. The other side edge 1b (the right side in FIG. 1, the left side of the folded plate roof)
A third locking portion 33 for locking to the aforementioned second locking portion 32, and a fourth locking portion 3 for locking to the third fixing piece 12 of the tight frame.
And 4.

The first locking portion 31, the second locking portion 32, and the fourth locking portion 34 form substantially U-shaped grooves 35, 36, 37 protruding outward. It is formed by. An inclined surface 35 is provided at a portion corresponding to each fixing piece 10, 11, 12 so that the folded plate roof 1, 1 can be fitted and locked from above.
a and 37a are preferably formed. Although no inclined surface is formed in a portion corresponding to the second fixing piece 11, if the second metal member 14 forming the fixing metal 9 is configured to be movable in the left-right direction as described above, an unreasonable fitting will not occur. It becomes unnecessary.

The third locking portion 33 has a curved cross section that locks the second locking portion 32 from above. The third locking portion 33 may be set so as to be locked to the first locking portion 31 from above.

As shown in FIG. 7, the folded-plate roofs 1, 1 are also provided with rising portions 1c, 1c at an intermediate portion so that they can be fitted and fixed to a tight frame 3 having an appropriate shape. It may be something. In this case, the locking and fixing portion may be formed by combining the shape of the one side edge 1a and the shape of the other side edge 1b.
It may be eight.

Further, the folding roofs 1, 1 may be of a tough type. That is, as shown in FIG.
The first fixing piece 10 which locks two places of the one side edge 1a and the second
The fixing pieces 11 are formed up and down, and the second fixing pieces 11 located above are bent and formed for tightening. On the other side of the tight frame 3, the other side edge 1 b of the folded-plate roof 1, 1
A third fixing piece 12 for locking the inside of the portion is formed.

As described above, the folded-plate roof 1 has the first metal member 13 and the second metal member 14 having the fixing pieces 10, 11, and 12, respectively. A first locking portion 31 that locks to the first fixing piece 10 and a second locking portion 32 that is bent and formed for tightening and that locks to the second fixing piece 11 are formed in this order from the inside. Further, on the other side edge 1b of the folded-plate roof 1, a third locking portion 33 bent for tightening, which is locked to the second locking portion 32 fixed to the second fixing piece 11, is fixed. A fourth locking portion 34 that locks to the third fixing piece 12 is formed in order from the outside.

Next, the cap 4 will be described. As shown in FIG. 1, the cap 4 is formed to be long from the roof ridge to the eave, having elastic locking portions 41, 42 on both side edges. The elastic locking portions 41 on one side edge (left side in the drawing) of the above-described elastic locking portions 41 and 42 are attached to the first locking portions 31 of the folded-plate roofs 1 and 1 fixed to the tight frame 3.
The elastic locking portion 42 on the other side edge (right side in the drawing) is the fourth locking portion 34.
Then, it is locked by fitting from above.

As shown in FIG. 9, the elastic locking portion 41 on one side edge is locked to the third locking portion 33, and the elastic locking portion 42 on the other side edge is fixed to the folded plate roof 1. Fourth locking portion 3 on other side edge 1b
It may be locked to a fifth locking portion 39 that is bent above the fourth locking portion and at the same height as the third locking portion 33.

With the above construction, the folded plate roof 1, 1
Are locked and fixed by the tight frame 3 at two locations on both side edges 1a and 1b. In particular, since the first locking portion 31 and the second locking portion 32 are locked at two points on one side edge 1a, even when a negative pressure is applied by blowing or the like,
In the deformation of the folded-plate roof 1 having the rising portion 1c, the curvature varies depending on the portion, and the first locking portion 31 and the second locking portion 32 are simultaneously disengaged from the first fixing piece 10 and the second fixing piece 11. Absent.

Further, even if the first locking portion 31 receives a greater force in the direction of disengagement, the second locking portion 32
Keeps the fixed state firmly, so that a resistance is given to the first locking portion 31 and the predetermined locking state is firmly held. Further, since the one side edge 1a of the folded roof 1 is firmly fixed in this way, the other side edge 1b of the adjacent folded roof 1 which is partially overlapped therewith and locked is also firmly fixed. Thus, the entire folded plate roofs 1, 1 can be in a good fixed state.

In order to obtain such a firmly fixed state, it is only necessary to fix the tight frame 3 on the base material 2 and then fit the folded roofs 1, 1 and the cap 4 sequentially. Extremely easy.

Further, since one side edge 1a of the folded plate roof 1 is locked at two places, the shape can be changed as compared with the conventional folded plate roof fixing structure, and a novel design feeling can be provided. Can also.

Further, since the cap 4 is fitted, it is possible to enhance the engagement of the folded plate roofs 1, 1 with the tight frame 3. And at the same time, improve waterproofing,
Good design feeling can also be obtained.

(Other Embodiments) As for the above-mentioned fixing fitting 9 constituting the tight frame 3, for example, as shown in FIG. 10, a single metal plate may be pressed to form the respective parts integrally. The configuration of each unit is denoted by the same reference numeral as in the case described above. With such a configuration, the number of components can be reduced, so that management and handling are facilitated.

Further, the tight frame 3 is not constituted by the tight frame body 6 and the fixing fitting 9, but a first fixing piece and a second fixing piece are formed vertically on one upper side of the tight frame body, and the tight frame body is formed. A third fixing piece may be formed on the other side of the upper part of the first frame, and the first fixing piece or the third fixing piece may be formed at least integrally with the tight frame body. For example, as shown in FIG. 11, a lower part has a fixed leg 5 fixed to the base material 2, a first member 51 having a first fixed piece 10 on the upper part, and a lower fixed leg 5 fixed to the base material 2. , The second having the third fixing piece 12 on the top
It is configured using the member 52.

That is, the first member 51 and the second member 52 are formed in the same shape, and the third member 53 having the second fixing piece 11 is disposed between the first member 51 and the second member 52 by the nut 7. 8 sandwiched between them. With such a configuration, the shapes of the members 51, 52, and 53 can be simplified, and costs can be reduced and management can be facilitated.

The second fixing piece 11 is integrally formed on one of the first member 51 and the second member 52 so that the two members 5
1, 52. Furthermore, each member 51,5
The integration of 2 and 53 may be performed by welding. Furthermore,
In the case of the above-described case including the first member 51, the second member 52, and the third member 53, as shown in FIG. 12, the opposite edges of the first member 51 and the second member 52 are engaged with each other. It is also possible to form engaging means that performs the engagement. This engaging means can be easily formed by, for example, comprising integrally formed engaging pieces 54 as shown in the figure. A receiving piece 53a that receives the lower end surface of the first member 51 is bent at the lower end of the third member 53. With this configuration, a correct positional relationship among the members 51, 52, and 53 can be ensured, and reinforcement can be performed naturally.

FIG. 13 shows an example in which the function of an inner gutter is added to the folded-plate roofs 1 and 1. That is, an inner gutter part 1e having a concave groove 1d is vertically provided at an end of one side edge of the folded plate roofs 1, 1. Should rainwater enter, this inner gutter 1e
Flows along. Since it is formed on the folded-plate roof 1, the configuration is simple, no special construction is required, and the handling is easy. In the drawing, reference numeral 14a is a reinforcing rib.
