Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metal roofing structure (9%) that is suitable for wrapping material applied to tile rods.

(Conventional technology) As for the conventional metal roofing structure.

As shown in Figures 8 to 1 (IJ), the applicant of the present application previously proposed, in 1987-147917, an example in which a wrapping material and a reinforcing material were combined and applied to tile rods for roofing. Disclosed.

That is, between the tile rods 2 installed on the shedding board 1 along the slope of the K-hung roof from one building to the eaves (direction of arrow A),
A roof plate 3 made by bending a rectangular short metal plate is combined with other pieces and laid continuously, or a long metal plate roof plate (not shown) is continuously laid, and then Reinforcement material 4
゜Wrapping material 5. A cap 6 etc. was applied to each tile rod 2 to fix the entire roof sheet 3 while processing both side edges of the roof sheet 3 relative to the tile rod 2.

When installing roof #3 one by one, install it in the 9 width direction (arrow B
After forming locking portions 8 in the shape of what is commonly known as a “haze-fold” by folding back on-site the short length plates along the respective ends along the “direction”,
A rising portion 9 is formed by bending both sides along the longitudinal direction (direction of arrow C) upward and engaging with the side surface 2a of the tile bar 2.

A plurality of metal plates are vertically roofed between the eaves and eaves by combining the locking parts 8 with the side surfaces 2a of the tile rods 2 and the rising parts 9 in contact with each other. When using a mackerel board as the roof board 3, a relatively low-hardness copper board, for example, should be used, and the roof board should be folded at appropriate pitches at the site, commonly known as "iris folding".
(not shown), the rising portions 9 are formed upward as described above, and vertical roofing is applied between each tile rod 2.

The reinforcing material 4 used for this roofing is the head 1 of the wrapping material 5.
7 has a head 11 having an outer surface shape corresponding to the inner surface shape of 0, and a pair of left and right ribs 12 are bent in the left and right direction of the head 11 along the longitudinal direction. The bottom surface 13ri of this rib 12 can freely come into contact with the top surface 2b of the tile bar 2.

The rib 12 is formed with a slight gap left at its base end, and the base ends 14a and 141) are in a non-contact state. Furthermore, clamping portions 15 are provided at both ends of the reinforcing material 40. This clamping portion 15 is.

It holds the side surface 2a of the tile rod 2 together with the roof plate 3, and when forming the reinforcing material 4 or providing the rib 12, the 2
A width W2, which is slightly smaller than the width W between the side surfaces 2a of the tile bar 2, is left between the both ends, and both ends are bent slightly inward to form the holding part 15 so as to provide elasticity.

(Problems to be Solved by the Invention) However, compared to such a conventional metal roofing structure, the cross-sectional shape of the roofing board 3 is a simple "-" shaped seed shape. from.

The shape makes it easy to combine with the wrapping material 5 and the reinforcing material 4, which improves the drainage performance of the 2 parts of the tile rod, and further improves the strength (durability) of the 2 parts of the tile rod against external force (pressure force). It is something.

Furthermore, connecting multiple rectangular short metal plates through the seam folds requires a lot of time and effort to form one bend. In some cases, if the cross-leaf folding at each predetermined pitch becomes inaccurate, it may cause distortion in the terminal part 1, for example near the eaves, because of the long length.These points are also desired to be improved. :,,.

This invention was made by focusing on such conventional technology, and it further improves drainage performance and strength (durability) against external force (pressure force), and requires less time and effort in construction, making it far more effective than conventional methods. To provide a metal roof shingle roofing structure that can be easily constructed and does not cause distortion near the end portion of the roof shingles.

(Ninth way to solve the problem) The metal roof shingle roofing structure according to the present invention is as follows.

To achieve the above purpose, a long metal plate.

Flattened in an S-shape, folded parts are formed across the entire width at predetermined pitches in the longitudinal direction, and then tile rods with symmetrical curved parts that spread upward are attached to both side edges of this metal plate. The rising part of the joint is bent to form a gutter-shaped roof board, and this roof board is laid between the alternating rods from the eaves of the roof to the ridge, and the rising part is engaged with the side of the tile rod. Each of the curved portions and adjacent curved portions are covered with a wrapping material made of tile rods.

(Function) If 11 base plates are laid continuously from the ridge to the eaves on the field board between the tile bars, the rising part will engage the side of each tile bar, and the curved part will touch the top surface of each tile bar. At this time, if a reinforcing material had been fitted to the tile rod in advance, the curved portion would be located above this reinforcing material. In this state, if the upper part of the rising part is further covered with a tile rod wrapping material, the cylindrical head of the wrapping material will be located and adjacent to each other so as to cover the curved part formed in the rising part. Conversely, the cylindrical head of the wrapping material is reinforced on the back side of the cylindrical portion formed by the curved portion, and the back surface of the wrapping material and the curved portion are brought into close contact. If the reinforcing material is applied in advance as described above, the curved portion may be sandwiched between the reinforcing material and the wrapping material with the curved portion extending between the cylindrical heads of both the reinforcing material and the wrapping material. In any case, the elongated roof sheet properly engages the side surface of the tile rod through the rising portions and curved portions formed on both edges thereof, and the cylindrical head of the wrapping material on the back side. This results in a structure that is closely connected to the back surface while reinforcing it.

(Example) The present invention will be described below based on the drawings. Hereinafter, the same reference numerals are given to the same parts as in the conventional art, and redundant explanation will be omitted. 1 to 7 are diagrams showing an embodiment of the present invention.

In the illustrated example, the metal roof shingle roofing structure (hereinafter simply referred to as roofing structure) is constructed by fitting a reinforcing material 4 onto each tile rod 2, and then bending a long metal plate 20. Lay the flattened roofing board 21 on the roofing board 1 between each tile rod 2 and nail it 25 from the side.
Then, a wrapping material 5 is applied to each tile rod 2 from above. Using this wrapping material 5, a curved portion (described later) is positioned between the cylindrical heads 10 and 11 of both the reinforcing material 4 and the wrapping material 5, and is fixed from the side of the wrapping material 5 with nails 25, and finally each tile A cap 6 is fitted onto the tip of the rod 2.

This roof plate 21 includes a long metal plate 20 in the longitudinal direction (
The folded portions 22, which are flattened and have an S-shaped cross section, are formed at predetermined pitches in the direction of arrow C) over the entire width. Also, on both sides along the longitudinal direction,
The width size W of the reinforcing material 4 corresponds to approximately A, and the reinforcing material 4
A rising portion 24 with a curved portion 23 extending approximately to the head 11 position is formed symmetrically.

This roofing board 21 is made of ceramic, and from the viewpoint of processing accuracy, efficiency, and effort, the folded part 22 is machined all at once at the factory. Figure 4) 1
It is then wound into a coil for convenient transportation and storage (see Figure 5).

The roofing board 21 wound into a coiled shape is necessarily carried to the construction site according to the IVC, and is rewound again into a long shape. It is separately delivered to the site, machined by nine machines to form the overall shape described above, and then laid on the roofing board 1.

Next, the action will be explained.

In a state where the reinforcing material 4 is fitted onto the tile rod 2 and the side surface 2a of the tile rod 2 is held between the clamping portions 15.

After unrolling the 7 tm root plate 21 wound into a coil and bending the rising portion 24 and the curved portion 23, this long roof sheet metal is laid between each tile rod 2. At this stage, the rising portions 24 on both sides of the longitudinal direction (direction of arrow O) of the roof board 21 come into contact with the side surfaces of the clamping portions 15 of the reinforcing material 4 (and are formed on the rising portions 24). The curved portion 23 extends above the head 11 of the reinforcing material 4 and is positioned in a well-protruded state.Next, by attaching the wrapping material 5 to the upper surface 2b side of each tile rod 2, the adjacent roof panels are 21 curved portion 23
Each tile bar 2 is covered with the tile rod 2 and fixed with nails 25.

As a result, the rising portion 24 of the roof plate 21. Especially the curved part 23
extends between each head 10°11 of the reinforcing material 4 and wrapping material 5,
Since it is located in an overhanging state and is in close contact with each head 10.11 of both the reinforcing material 4 and the wrapping material 5, it prevents rainwater from entering upward into the rising portion 24 of the roof board 21, further improving drainage performance. At the same time, external forces applied from each direction are effectively dispersed to improve the durability of the wrapping material 10 against external forces and to relatively improve its strength.

In other words, when an external force or pressing force is applied from above (in the direction of the arrow) or diagonally upward (in the direction of the arrow) in Figure 1, the pressing force is applied to the reinforcing member 4 and the curved portion projecting above the reinforcing member 4. 23
Even if an excessive pressing force is applied, the wrapping material 10 is received and dispersed, effectively supplementing the strength of the wrapping material 10 and preventing its deformation.

(Effects) Since the metal roofing structure of the present invention is as explained above, it has the following effects.

(b) The rising part of the roof board is curved and extended, making it easy to prevent water from entering, and even in cases where there is a large amount of rainfall and a high degree of rainwater infiltration, such as during a typhoon, water drainage is maintained. You can improve even more.

In addition, the curved portion comes into close contact with the back surface of the head of the wrapping material, further improving drainage performance.

(b) Since the back side of the head of the wrapping material is reinforced at the curved part of the roof board, the strength of the wrapping material is relatively improved and deformation can be prevented.

(c) If the VC roofing board is laid between the tile bars, the rising part of the roofing board will engage with the side surface of the tile bar, and the curved part will protrude above the upper surface of the tile bar.

Next, when covering it with a wrapping material, it is guided by the curved part and the rising part, so that the ninth step of attaching the wrapping material is easy and requires no effort.

2) Since the folded part is pre-processed into a long metal plate all at once, it can be processed with high precision, and it is possible to prevent end partial pressure distortion from occurring when vertically roofing is done, making construction easier. The effect of... can be expected.

Further, according to the embodiment, the following incidental effects can also be obtained.

(e) When reinforcing material is attached to the tile rod in advance.

Since the curved part of the roof board is sandwiched between the heads of both the reinforcing material and the wrapping material and brought into close contact with each other, the function of preventing water from entering is enhanced, and the degree of reinforcement to the wrapping material is also improved.
