Description

[Detailed description of the invention] [Industrial application field] This invention relates to a connection structure for roofing materials in a horizontal roof using roofing materials made of iron plates or the like.

[Conventional technology]

When roofing is done using roofing materials such as iron plates, conventionally the simplest method is to overlap the roofing materials on the rafters that make up the roof and fix them with nails. There is also a connection structure as shown in FIG.

In this figure, 1 is a roofing material made of iron plates, 2 is a cap, 3 is a throw board, 4 is a decorative board,
These are also made of iron plates or the like.

5 is the base of the roof, which consists of wooden boards laid all over the rafters of the roof. The length of the cap 2 is shorter than the width of the roofing material 1, and the step board 3 and the decorative board 4 are longer than the width of the roofing material 1.

The step board 3 has sloped edges 6 on both sides thereof facing diagonally inward.
and multiple rows (two rows each on the left and right in the illustrated example) of reinforcing ribs 9.
form.

Further, both side edges of the decorative board 4 are folded inward at the lower part to form inward edges 10.

In the case of this conventional example, first, the base plate 3 is placed on the base 5.
, and the inverted T-shaped leg 11 at the bottom of the cap 2 is engaged with the center of the stop plate 3.

Next, insert the side edges of the left and right roofing materials 1 between the sill board 3 and the overhanging portions 12 on both sides of the upper part of the cap 2, and then insert the inward edges 10 on both sides of the decorative board 4 placed over the cap 2. It is inserted between the overhanging part 12 and the roof material 1.

Thereafter, the left and right roofing materials 1 are joined together by pressurizing and caulking the footboards 3 and decorative panels 4 protruding from both ends of the cap 2 using appropriate pressure means.

[Problem that the invention attempts to solve]

In the conventional connection structure mentioned above, where the roofing materials are overlapped on the rafters and fixed with nails, the nails are exposed to the outside and look unsightly, so it is recommended to put a patch between the parts where the nails penetrate to prevent rain leakage. However, even with this, there was a problem that leaks were likely to occur.

Although the structure shown in Fig. 5 has a good appearance, it has a complicated structure, and when assembling it, the edge of one roofing material 1 is placed on top of the roofing board 3, and then the entire cap 2 is attached. This requires a very labor-intensive construction process in which the decorative board 4 is attached on top of the roofing board 3, the edges of the other roofing material 1 are overlapped, and then the decorative board 4 is attached, resulting in a long construction period.

In addition, since the inward edge 10 of the decorative board 4 is in direct contact with the surface of the roofing material 1, when the roofing material 1 slides against the inward edge 10 due to temperature changes, the inward edge 10
There were problems such as the coating on the surface of the roofing material 1 peeling off at the tip of the roofing material 1 and accelerating corrosion.

[Means for solving problems]

In order to solve the above problems, this idea places a step board with multiple reinforcing ribs on the roof base, and places the side edges of the left and right roofing materials in the center of this step board as appropriate. They are placed facing each other with a gap between them, and on this gap, a central convex part in the longitudinal direction is provided at the center of the lower side, and convex parts with rounded edges on both sides of the lower surface are provided on both sides of the central convex part in the longitudinal direction. Further, on the lower side of the central convex part, a cap having a rectangular support plate with a width that can enter the gap between the roofing materials from above is fixed to the central convex part so as to be inclined laterally at a predetermined angle with respect to the central convex part. A gap is created between the roofing material and the cap by placing the protrusions on both sides on the left and right roofing materials, and the support plate is placed between the roofing material and the end plate in the gap between the roofing materials. By tilting it in the lateral direction, it is prevented from slipping out of the gap.

〔Example〕

FIG. 1 shows a house with a hipped roof in which this invention was implemented, and FIG. 2 is an enlarged sectional view taken along line A--A in FIG. 1.

In the embodiment shown in FIG. 2, the base 5 of the roof is the same as the conventional roof base 0 shown in FIG. 5, and a stop plate 15 made of an iron plate or the like is placed thereon. This step board 15 is a simple one having a plurality of reinforcing ribs 16 and sloped edges 17 on both the left and right sides, and the side edges of the left and right roofing materials 18 made of iron plates etc. are placed on top of it. A suitable gap a is provided between the opposing side edges of the material 18. Further, each roofing material 18 is engaged with a bent portion provided at an overlapping portion in the vertical direction, and the portion of the roofing material 18 below this overlapping portion is fixed to the base 5 with nails.

Reference numeral 21 in FIG. 2 is a cap, and a central convex portion 22 is provided at the center of its lower part.The central convex portion 22 has a width considerably narrower than the width of the gap a, and its center line and the center line of the cap 21 are similar to each other. are matched.

A rectangular support plate 23 made of an iron plate or the like is fixed to the lower part of the central convex portion 22 . This support plate 2
3 is inclined laterally with respect to the central convex portion 22 as shown in FIGS. 3 and 4, and is fixed integrally by welding or other arbitrary fixing means.

Furthermore, as shown in FIG.
2 is inserted into the gap a in parallel with the gap a, it should be such that it enters the lower part of the left and right roofing materials 18 from the lower part of both sides of the gap a.

Further, on both sides of the central convex portion 22 of the cap 21, there are provided convex portions 24 that are slightly lower than the convex portion 22 in the longitudinal direction.
shall have an appropriate radius.

The cap 21 is stacked so as to straddle the opposite side edges of the left and right roofing materials 18 fixed on the base 5 as described above, and is tilted laterally as shown in FIG. After covering and fitting the support piece 23 into the gap a in parallel with the gap a, lower it and position it below the roofing material 18, turn the cap 21 laterally to open the cap 21 as shown in Fig. 4. When made parallel to the gap a, the support plate 23 is inclined laterally with respect to the gap a, and the portions e near both ends thereof become the lower sides of the side edges of the roofing material 18 as shown in FIGS. 2 and 4. , it will not come out upwards.

At this time, the convex portions 24 on both sides are connected to the roofing materials 18 on both sides.
Place it on the side edge of the

The decorative board 25 is placed on the cap 21 in advance, and the left and right inward edges 2 of this decorative board 25
6 are wound around the lower surface of both sides of the cap 21 and fixed.

Note that both ends of the cap 21 and both ends of the decorative board 25 are appropriately engaged with engaging portions at both ends of the roof material 18 and fixed.

[Effects] As mentioned above, this idea
A step board with multiple reinforcing ribs is placed, and the side edges of the left and right roofing materials are placed facing each other with an appropriate gap in the center of this step board. has a central protrusion in the longitudinal direction, and is provided with rounded protrusions on both sides of the longitudinal direction and on both sides of the lower surface, and furthermore, on the lower side of the central protrusion, a hole is formed from above into the gap between the roofing materials. Since the cap is fixed to a support plate that can fit inside the roof and has a width wider than the central convex part and is tilted laterally at a predetermined angle with respect to the central convex part, it is necessary to first apply the roofing material and then cover the cap. If you insert the support plate into the gap between the roofing materials while tilting the cap laterally, and then make the cap parallel to the gap when the support plate is on the underside of the roofing material, the cap will completely fill the gap. The cover and support plate also prevents it from falling out.

Therefore, the structure of the connection part is significantly simpler than the conventional connection structure of roofing materials, and the connection work is also simple and easy.

In other words, in the past, it was necessary to overlap the side edges of one roof material with a waste board, then attach a cap, and then attach the other roof, but in the case of this invention, the roof material was placed on the underside of the cap. Since the support plate is slanted, the left and right roofing materials can be first fixed as described above, and then the cap can be attached, thereby significantly shortening the construction period.

In addition, the side edges of the protrusions on both sides of the lower surface of the cap are rounded, and the protrusions on both sides contact the top surface of the roofing material, creating a gap between the roofing material and both sides of the cap. Even if the roofing material expands and contracts due to temperature changes and sliding action occurs between the roofing material and the convex parts, there is no fear that the paint film on the surface of the roof sheet will peel off, and the decorative board placed on the cap will not peel off. This has the effect that the inward facing edges on both sides do not rub against the roof board and cause scratches on the paint film.
