DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shingle joining structure for connecting adjacent shingles with each other using a hook and a cap.

[0002]

2. Description of the Related Art A fitting type roof shingle joint structure using a long gutter-shaped through-hook as a joining element is disclosed in Japanese Patent Publication No. 3-63622.
It is known in the publication. There, a through-hook having a U-shaped cross section in front view is screwed to a roof base plate, and a roof plate is joined thereto. More specifically, a connecting portion extends outward from both left and right sides of the upper end of the through-hook, and the connecting portion provided on the roof plate is put on the connecting portion of the through-hook from above to engage the two connecting portions. Finally, the cap is fixed by press-fitting the cap from above. The two connecting portions are each formed in a substantially R-shape.

[0003]

The fitting type roof shingle joint structure requires more labor and time than conventional tile roofing in which the three members of the through-hook, the roof shingle and the cap are fastened together. It has the feature of being significantly reduced. On the other hand, since the joined state is maintained only by the elastic stress of the through-hanger, the roof panel, and the cap, there is a problem in that it is difficult to sufficiently obtain the joint strength of the three members and the load resistance and wind resistance are small. In particular, when a negative pressure acts on the roof slab to lift the roof slab away from the roof slab, the joint between the roof slab and the through suspension is easily dissociated.

In the above-mentioned Japanese Patent Publication No. 3-63622,
The connecting part of the roof shingle is put on and connected to the connecting part of the slinger from above. For this reason, it is difficult to obtain wind resistance when a negative pressure acts on the roof slab. This is because only the cap mainly maintains the connected state against the negative pressure, and the connecting portion on the side of the through-hanger hardly contributes to maintaining the connected state when the negative pressure acts. When the connecting portion of the roof plate is engaged with the connecting portion of the through sling from below, the connecting portion of the through sling and the cap cooperate with each other to oppose the negative pressure. However, there is a limit to this, and the wind resistance when a negative pressure acts is still insufficient.

[0005] Increasing the thickness of the roof slab, through-hanger, and cap can improve the connection strength of the joint to some extent, but in this case, material costs and processing costs are high. The ease of construction may be impaired.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the connection strength of a joint in a fitting type roof slab joint structure using a through-hanger, and to enhance the load resistance and wind resistance of this type of roof.
SUMMARY OF THE INVENTION An object of the present invention is to improve the structure of a through-hanger to improve the connection strength of a joint without significantly increasing the cost, and to obtain an economically advantageous fitting type roof shingle joint structure. .

And a cap 5 for maintaining the connected state of the cap 4. The roof plate 4 has connecting arms 7 rising upward on both left and right side edges thereof.
And a connecting portion 8 that engages from the lower surface side. Further, an engagement rib 9 with which the cap 5 is engaged from the outside is provided in the middle part of each connecting arm 7 in the vertical direction. The through hook 3 is formed in a gutter shape that opens upward with a pair of left and right arms 11 that rise upward and a bottom 12 that connects the lower ends of both arms 11, and is connected from the upper end of each arm 11. The portion 13 is formed so as to project outward, and a fastening seat 17 through which a fastener 19 is inserted is provided on the bottom portion 12. A step portion 24 is protruded from the upper portion of the outer surface of each arm portion 11, and the connecting portion 8 of the roof plate 4 is engaged with the step portion 24. Specifically, the through hanging element 3

In the assembled state, the cap 5 is located on the outermost surface, and the connecting portion 13 of the through sling 3 and the connecting portion 8 of the roof plate 4 sequentially weight inside the cap 5. That is, the connecting portion 8 of the roof panel 4 is engaged and held from below on the connecting portion 13 of the through-hanger 3 on the upper surface side.
In addition, the free end of the connecting portion 8 of the roof plate 4 is received by the step portion 24 protruding above the outer surface of the arm portion 11, thereby preventing the entire connecting portion 8 from tilting downward. As described above, when the connecting portion 8 of the shingle 4 is located at the innermost surface, and the connecting portion 13 and the step portion 24 have a joint structure in which the connecting portion 8 of the shingle 4 is restrained so as not to be tiltable downward. Even if an external force is applied to the roof plate 4 in a direction (P direction in FIG. 2) that floats away from the roof base material 1 due to a strong wind or the like, the connecting portion 8 of the roof plate 4 collides with the step portion 24. In this case, the connected state can be reliably maintained. According to the through hook 3 in which the vertically extending reinforcing rib 23 is provided on the arm portion 11 and the step portion 24 is formed on the upper end thereof, the deformation stress of the arm portion 11 connected to the connecting portion 13, particularly the arm portion 11 The bending stress at the time of bending in the middle part is enhanced, and the connection strength of both connection parts 8 and 13 is further improved.

I made it possible. Further, a step portion 24 is provided on the arm portion 11 of the through hook 3, and the step portion 24 and the connecting portion 13 restrain the connecting portion 8 of the roof plate 4 from tilting downward so that the joint portion is dissociated. Prevented. Therefore, the connection strength of the joint portion is increased as compared with the conventional method, and the load resistance and wind resistance of this type of roof, particularly the wind resistance when a negative pressure is applied, can be sufficiently improved. The step portion 24 and the connecting portion 13 provided on the arm portion 11 of the pass-through hanger 3 prevent the connection portion 8 of the roof plate 4 from being dissociated, so that, for example, the cap 5, the roof plate 4, the pass-through hanger 3 Compared to the case where the thickness of the plate is increased to improve the connection strength, the fitting type roof can be constructed with less material cost and only by considering the increase in the processing cost required for forming the stepped portion 24. Can be inexpensive. According to the through hook 3 in which a group of vertically long reinforcing ribs 23 is provided on the arm portion 11 and the step portion 24 is formed at the upper end of the reinforcing rib 23, the deformation stress against an external force for bending the arm portion 11 can be increased. In addition, the connection strength between the through suspension 3 and the roof plate 4 can be improved. Structural strength against an external force that tends to crush the joint can also be improved.

The through hook 3 is formed in a long elongated gutter shape before and after opening upward by a pair of left and right arms 11 rising diagonally upward and a bottom 12 connecting lower ends of both arms 11. Each of the trapezoidal connecting portions 13 is formed to protrude outward from the upper end of the arm portion 11, and the engaging edge 14 is formed by bending inward at the free end of each connecting portion 13.

At the upper part of the outer surface of each arm portion 11, vertically long reinforcing ribs 23 are protruded at regular intervals in the longitudinal direction, and a step portion 24 is formed at the upper end of each group of these reinforcing ribs 23. On the bottom 12, a pair of left and right leg walls 15 that are continuous with the lower ends of the left and right arm portions 11 and a flat seat wall 16 that connects the upper ends of the two leg walls 15 are provided with an equiped base-shaped fastening seat 17. Form. By forming the fastening seat 17 in an upwardly projecting shape in this manner, an acute-angled gutter portion 18 can be formed in a V-shape between the lower ends of the respective leg walls 15 and the respective arm portions 11, and the fastener 19 is inserted. The seat wall 16 can be located above the gutter bottom. As the fastener 19, a self-drilling screw,
A tapping screw or the like is used, and as shown in FIG.
8, the seat wall 16 is fastened and fixed. By using the washer 28, the fastening force of the fastener 19 can be transmitted to the seat wall 16 via a wider contact surface. Even if rainwater infiltrates into the penetrating hanger 3, the rainwater flows to the eaves side via the gutter portion 18 and does not reach the fastener 19 on the seat wall 16, so that the rainwater flows under the penetrating hanger 3. It will not go around. As shown in FIG. 3, each connecting portion 13 of the through-hanger 3 has an upper wall 11a of the arm portion 11, a horizontal wall 13a extending horizontally outward from an upper end of the upper wall 11a, and an obliquely downward facing continuous horizontal wall 13a. And a vertical wall 13b formed in a trapezoidal shape.

The cap 5 is formed of a long frame having a flat trapezoidal cross section, and is passed through the left and right sides of the main surface wall 5a.
The engagement arms 20 which are fitted to the connecting portions 8 and 13 are bent downward, respectively, so that the lower ends of the respective engagement arms 20 are pressed into the engagement ribs 9 of the roof plate 4 from outside. A letter-shaped engaging edge 21 is provided. The tip of the engaging edge 21 is folded inward to avoid exposing the cut to the outer surface. The cap 5 and the through-hanger 3 can also be formed of various metal plates similarly to the roof plate 4, and in this example, a plated coated steel plate was used as a forming material.

At the time of construction, the shingle 4 and the through hook 3 are assembled alternately in the left-right direction. Specifically, after positioning the through-hanger 3, the fastener 1 is attached to the seat wall 16 of the fastening seat 17.

Further, the connecting portion 8 on the other side of the roof plate 4 is engaged with the lower surface side of the connecting portion 13 of the through-hanger 3, and the free end of the connecting portion 8 is engaged with the step portion 24 by latching. The engaging edge 14 is engaged with the engaging rib 9 from outside. Then, the newly joined through-hanger 3 is positioned with reference to the previously temporarily-mounted through-hanger 3, and is temporarily fixed by the fastener 19. In this state, the fastener 19 of the threader 3 temporarily fixed earlier is screwed in and permanently fixed.

As the fastener 19 is screwed into the roof base material 1, the seat wall 16 of the fastening seat 17 is strongly pressed by the washer 28,
The left and right leg walls 15 are inclined toward the inwardly inclined side. When the two leg walls 15 are inclined, the two arm portions 11 that come into line contact with the underlaying material 2 are also inclined in the same direction. As a result, since the left and right connecting portions 13 approach each other to draw the connecting portions 8.8 of the roof plate 4, the joining strength of the connecting portions 8 can be improved. Finally, the cap 5 is press-fitted, and the main surface wall 5a closes the upper surface of the opening of the through-hanger 3, and the engaging edge 21 is engaged with the engaging rib 9 from outside through the locking edge 14. .
