Description

[Detailed description of the invention]

【0001】

[Industrial Application Field] This invention applies from top to bottom,
In other words, it relates to a horizontal metal roof that is roofed from the ridge side to the eave side.

【0002】

BACKGROUND OF THE INVENTION Conventionally, most metal roofs and exterior walls are roofed in order from the bottom to the top. Therefore, it is not possible to decide in advance where the roofing will end, at the ridge in the case of roofing materials, or at the eaves in the case of exterior wall materials.
The roofing was done sequentially from the bottom to the top, and the work was completed by cutting and processing the materials to fit the ridge or eaves. However, this type of fitting work is carried out at a high place, the fitting of each part is troublesome, and various problems remain in terms of rain protection.

[0003] Therefore, the present inventor first developed a structure that can be roofed from the top to the bottom. FIGS. 7 and 8 show, as an example, the case where the present invention is applied to metal roofing. In the figure, 11 is a C-channel shaped main building, and 12 is a rafter which is a face plate mounting member fixed perpendicularly to the main building 11 with fixing devices 13 such as bolts and nuts. On the upper part of the rafters 12, there is a horizontal roofing material 20 made of a metal face plate etc.
A pair of claws 14, 15 of a pitch corresponding to the width of the roof 20 are cut and raised at equal intervals, and the lower part of the roof 20 is fixed with the respective brackets, that is, the claws 14, 15, and the roof is successively roofed from the ridge side to the eaves side. I'm trying to keep it that way. For this reason, the connections between each roofing material are as follows.

[0004] That is, as shown in FIG. 8, the eave side molded part 1 of each roofing material 20 is formed with a receiving piece 20a that is curved inward in a U-shape, and is extended to the lower end of this receiving piece 20a. The edge of the extension piece 20b is held by the claw 15, and the tip of the receiving piece 20a is held by the claw 1.
By locking and fixing at 4, it is fixed on the rafter 12. Moreover, the ridge side molded part 4 of the roof material 20 has a curved part 20c facing upward, and a V-shaped bent part 20d below the curved part 20c. Then, a receiving piece 20 of the roof material 20 on the upper side
By fitting the ridge-side molded part 4 of the lower roofing material 20 into the inside a and fixing it with claws 14 and 15, the roofing extends to the eaves side.

【0005】

[Problem to be solved by the invention] Each roofing material 20
Due to the presence of a bent portion 20d and a curved portion 20c inside the receiving piece 20a at the connecting portion between them, rainwater that has entered from the gap S as shown by the arrow is returned by these, and generally no rain leaks occur. However, in the event of heavy rain accompanied by strong winds blowing up toward the ridge, such as during a typhoon or strong winds and rain, rainwater may enter through the gap between the curved portion 20c and the receiving piece 20a, causing rain leaks. I was afraid. In order to solve this problem, it is necessary to create a more complicated labyrinth structure between the roofing materials 20. Therefore, an object of the present invention is to provide a roof structure in which a metal roof is covered from the ridge side to the eave side, which greatly improves rain protection without impairing workability. It is something.

【0006】

[Means for Solving the Problems] In order to achieve the above object, in the present invention, in a roof that is roofed by engaging the metal face plate 32 from the ridge side to the eave side, the eave side molded part 1 of the face plate 32 has the following features: is the hanging part 33
, a first bent portion 34 bent toward the ridge, a holding portion 35 consisting of a rising portion 2, a second bent portion 30a bent toward the ridge, and an inner hanging portion 3; A third bent portion 37 extending directly below the rising portion 40 of the side molded portion 4, a hanging piece portion 38, and a fixing portion 39 are sequentially formed.
0, a first bent portion 41 bent toward the ridge side, a rising portion 42, a second bent portion 30b bent toward the ridge side, and a bent portion 43 held by the holding portion 35 are sequentially formed, Upper locking part 2 for locking the face plate 32 at one end
02, and has a lower locking part 203 at the other end for fixing the face plate 32, and a hanger 200 provided with a fitting hole 201 into which a pair of claws 14 and 15 protruding from the rafter 12 are fitted. The hanger 200 is fixed on the rafter 12 by caulking a pair of claws 14 and 15 provided on the rafter 12, and the eave side molded part 1 is fixed on the rafter 12, and this eave side It is characterized in that the ridge side molded part 4 is fitted and locked to the molded part 1.

【0007】

[Function] When the eave side molded part 1 and the ridge side molded part 4 are engaged with each other with the above configuration, rain blown up along the face plate by the rising part 40 is
In addition to making it difficult to enter the mating surface, since a plurality of bent portions and spaces are formed inside the engaging portion, rainwater can be reliably prevented from entering.

[0008] Furthermore, since the eave side end of the third bent portion 37 and the lower end of the rising portion 40 of the ridge side molded portion 4 are joined, the face plate 32 can be reliably supported.

[0009] Moreover, since the hanger 200 is provided separately and the engaging portion of the eaves side molded part 1 can be firmly fixed with the hanger 200 through the pair of claws 14 and 15, it is possible to prevent strong winds. It has great durability against rain. Moreover, since the hanger 200 is a separate piece, it can easily adjust the width and position of the roofing material, and it can also be made of a material that matches the material of the roof, which prevents electrochemical corrosion, for example. Measures can be taken such as:

[0010] Furthermore, the design effect can be increased by increasing the step difference, and it can be installed using only a tool such as a hammer, and it is also excellent in workability because it only needs to be hooked from the top to the bottom.

As shown in FIG. 2, the hanging portion 33 of the eave side molded portion 1 and the rising portion 40 of the ridge side molded portion 4 are formed so as to be substantially on the same plane at the engagement position.

[0015] In FIG. 3, 12 is a metal rafter, and a pair of locking claws 14 and 15 are cut and formed on the rafter 12. 200 is a hanger, and this hanger 200 is obtained by press molding a thick metal plate, etc.
An upper locking portion 202 is formed in advance in the shape of a hook on the upper edge, a tongue-shaped lower locking portion 203 is formed on the lower edge, and the locking claws 14 and 1 are formed in the center of the hanger 200.
A pair of fitting holes 201 are bored corresponding to the holes 201 to be locked. Then, the locking claws 14 and 15 are passed through the fitting hole 201 of the hanger 200, and the locking claws 14 and
By caulking 15, the hanger 200 is fixed on the rafter 12.

[0016] The above-described bent shape is obtained by processing both longitudinal ends of a long metal material, such as a steel plate, a stainless steel plate, or a colored iron plate, which is the forming material of the face plate 32, using a roll forming machine.

[0017] Hereinafter, in order to roof from the ridge side to the eave side using the roof plate face plate 32 formed in this way, first, the face plate 3 is attached to a fixing member (not shown) on the ridge side.
The ridge side molded portion 4 of No. 2 is fixed. Next, the fitting hole 201 of the hanger 200 is fitted between the pair of claws 14 and 15 on the rafter 12, and the fixing part 39 of the eave side molding part 1 is inserted into the upper locking part 202 and the lower locking part 203, respectively. and the locking protrusion 36, and bend and deform the lower locking part 203 with a hammer or the like to attach the eave side molded part 1 to the rafter 1.
2. Fix it on top.

[0018] Next, the ridge side molded part 4 of the eave side face plate 32
is inserted into the fitting space d, the rising part 42 of the ridge side molded part 4 is brought into contact with the rising part 2 of the eave side molded part 1, and the first bent part 41 and the bent part 43 are made to correspond to each other. The first bent part 34 and the second bent part 30a of the eave side molded part 1 are joined so as to fit tightly. In this case, the lower locking portion 203 is bent in advance, and the fixing portion 3 is inserted into the lower locking portion 203.
It is also possible to force fit using the elasticity of No. 9. Note that f is the second
Bent parts 30a and 30b, rising part 2 and bending part 43
It is a space formed by Therefore, by performing the above-mentioned work sequentially from the ridge side to the eaves side, the roof surface will be raised.

[0019] FIG. 4 is a configuration diagram of main parts of a modified example of the present invention. The difference from the first embodiment is that the hanger 20
A U-shaped bent part 401 is formed at the point where the shape of the upper locking part 202 of 0 extends so as to cover the holding part 35 of the eaves side molded part 1, and at the rising part 40 of the ridge side molded part 4. This is the point.

[0020] In the modified example shown in FIG. 4, since the hanger 200 is large, it is possible to lock up to the holding part 35 of the eave side molded part 1, and the fixing of the face plate 32 to the rafter 12 is similar to that of the first embodiment. It is even stronger than the original. Moreover, since the U-shaped bent portion 401 discharges rainwater in a U-shape, the effect of preventing rainwater from entering can be further enhanced.

[0021] FIGS. 5 and 6 are main part configuration diagrams of other modified examples of the present invention. The difference from the first embodiment is that there is no locking protrusion 36 protruding toward the ridge side at the lower part of the inner hanging part 3 of the eave side molded part 1, and the hanger 200
