Description

[Detailed Description of the Invention] This invention relates to a horizontal step roofing structure used mainly for the exterior of a roof.

Metal-based roofs generally have an excellent appearance of luxury and beauty, and here we will discuss a conventional example of the exterior structure of a horizontally tiered roof, which is constructed by interconnecting multiple horizontally long metal plates, as shown in Figure 1. This will be explained with reference to FIG.

The base material 1 that forms the base material is a single wooden board, and the outer panels 2A, 2B, 2 of each stage are made of a horizontally long metal plate.
C is a uniform plate with a fixed length and a fixed width.

Therefore, the shape of each of the outer panels 2A to 2C is such that the upper half thereof is formed into a flat plate that overlaps the base plate 1, and at the upper end of the upper half, there is a protrusion 3 that is bent diagonally outward in a wave shape. and an edge 4 with a dish-shaped cross section following the protrusion 3 are formed.

On the other hand, the lower half of the outer plates 2A to 2C is formed into a floating slope, and a joint 5 having a cross-sectional shape that wraps around the protrusion 3 is formed at the lower end of the slope.

These outer panels 2A to 2C are attached sequentially starting from the lower outer panel. That is, first, the joint 5 is hooked onto the protrusion 3 of the lower outer panel, and then the edge 4 is attached downward with a nail 6. Main plate 1
This process is repeated to cover the entire surface of the base plate 1 with the outer panels.When the roof is full, each of the outer panels 2A to 2
C is fixed to the base plate 1 at two places, the upper end and the lower end, and the nails 6 are hidden inside and cannot be seen from the outside.

However, such a conventional exterior structure has the following problems.

(a) The waterproofness of the joint is low.

Since a gap is likely to be formed at the contact surface between the joint 5 and the protrusion 3, rainwater sucked up to the upper surface of the protrusion 3 by capillary action accumulates in the edge 4, thereby corroding the nailed part of the base board 1.

(b) Weak wind resistance.

Since the lower half of the outer panels 2A to 2C is floating, in strong winds, the entire outer panel is likely to float up from the base plate 1 and become damaged. Especially if the nails 6 are not fastened properly, even a slight breeze will cause the entire outer panel to float upwards. The outer panel is easily deformed or peeled off.

(C) Sound insulation effect is low.

Since there is a space between the outer panel and the base panel 1, external noise enters the room through the roof.

(d) Appearance is poor.

Since the roof surface is almost flat, it lacks a solid appearance when viewed from the ground.

(e) The workability of the outer panel is poor.

Since the outer panels 2A to 2C are directly nailed to the base board 1,
Not only is it troublesome to position the outer panel, it is difficult to correct the mounting position, and it is troublesome to repair or replace the outer panel.

The present invention was made to solve the above problems, and the purpose of the present invention is to provide waterproof, windproof,
To provide a horizontal step roofing exterior structure that has high sound insulation properties, is easy to construct, and has an excellent appearance.

Hereinafter, the present invention will be explained based on an illustrated embodiment in which a body plate is used as the metal plate.

In the exterior structure of the embodiment, as shown in FIGS. 3 and 5, the base to which the outer panels 7A to 7C are attached is formed of multiple stages of base plates 8 that extend horizontally, and each stage has a base plate 8. The connecting portion between them is attached so that a step slightly larger than the thickness of the base plate 8 is formed.

To explain this more specifically, joiners 10 made of hard non-combustible material are provided along the edges of the base plate at regular intervals on the rafters 9 of the roof, and these joiners 10 are shown in FIG. As shown, the cross section is approximately S-shaped, and the upper plate 10
In the upper engaging groove 10c formed between b and the middle stage,
The lower end of the base plate 8 is engaged, and the middle stage and the base plate 10
The lower engagement groove 10d between the above-mentioned engagement groove 10C and
It has a structure in which the upper ends of the downstream base plates 8 are fitted alternately to the base plates fitted to the base plates 8.

Note that the board 10a of the joiner 10 is fixed to the rafters 9 by driving nails 16, and in addition, the upper surface of the base plate 8 is usually covered with a waterproof base sheet, but this is omitted in the figure. has been done.

Each of the outer panels 7A to 7C has a vertical width of 30 cm, for example.

It is a metal plate member of a fixed length and uniform shape, such as 8 m in width, and is formed into a sheet metal by roll forming and press forming.The formed shape will be described below.

The outer panels 7A to 7C are flat veneers except for the upper and lower ends, but in order to reinforce the molding rigidity of the flat surfaces and to reduce expansion and contraction due to temperature, It is also possible to provide a large number of projections and recesses 11 on the entire surface.

Note that the illustrated unevenness 11 has an irregular uneven shape.

Next, at the upstream ends of the outer panels 7A to 7C, a folded part 12 is formed with a step corresponding to the thickness of the joiner 10 and the size of the engagement groove, and on the downstream side of this folded part, there is an overlapping part. A folded collar 14 having a hook-shaped cross section is provided.

This brim 14 is folded over and over, increasing its rigidity.
In addition, the brim 14 provides shade to the roof, resulting in a dignified exterior structure.

Further, the folded outer plate of the collar 14 is shaped to further extend to the upper surface and be superimposed on the upper plate 10b of the joiner.

Further, the lower ends of the outer panels 7A to 7C are bent inward, and a seam 15 for tightening the collar 14 is formed.

The seams 15 serve to firmly fix the collar 14, further reinforce the collar 14, and significantly increase the rigidity of the collar.

The collar 15 also serves to prevent rainwater from entering, but even if the layer penetrates, the flap 15 will extend until the folded outer panel of the collar 14 further overlaps the upper panel 10b of the joiner 10. This further improves the effectiveness of preventing rainwater from entering.

As shown in FIG. 3, are the outer panels 7B and 7C adjacent to each other below? In A and 7B, each seam 15 is folded into the back side of the lower collar 14 by processing during assembly.

These outer panels 7A to 7C are sequentially attached to the rafter 9 by the respective joiners 10 starting from the lower outer panel, that is, first, the ribs 15 are hooked onto the ribs 14 of the adjacent panels. Thereafter, using a suitable tool, the flap 15 is folded in and crimped onto the collar 14 as described above.

In addition to driving the nails 16 described above, the joiner 10 can join the rafters 9 by means of screws, bolts, screws, anchors, welding, etc.
Fixed to.

In addition, a water return 13 having a convex cross section may be provided at the center of the upper surface of the folded portion of the outer panel to further enhance the effect of preventing rainwater from entering.

The upper end of the folded portion of this outer panel has a structure in which the upper end of the joiner is wrapped around and fixed.

With this, the joiner does not only join the base plate 8e, but the outer plate? A.

7B, and the strength of the horizontal step roofing exterior structure is further improved.

Furthermore, the space formed by the upstream end of the outer panel and the roll-up fixing part of the joiner becomes a retention area for even rainwater that has penetrated, and the effect of preventing rainwater infiltration is significantly enhanced.

The joiner can be formed, for example, in the following shape other than the shape described above.

(a) Separate 1 (see Figure 6) This joiner 20 is formed by folding the upper plate 20a to form a double plate, and the strength of the winding and locking of the tip of the floating part of the outer plate and the outer plate are the same. This is intended to increase the plate holding strength.

<bl Separate 2 (see FIG. 7) This joiner 21 has an upper engagement frame 22 and a lower engagement frame 23 separated and fastened together with screws 24. This is intended to simplify the manufacturing process of the joiner 21.

(C) Separate 3 (See Figure 8) This joiner 25 is made by integrating an upper frame 22 similar to the joiner 21 in the previous section and a double-legged lower frame 26 with screws 24. This is intended to increase the strength of attachment to 9.

The exterior structure of the embodiment configured as described above has the following excellent characteristics.

(a) Waterproofing of the connecting part of the outer panel Since the seam 15 and the collar 14 are crimped with a tool, there is almost no gap in the connecting part, and even if there is some gap, it will not be necessary to close the upstream part of the outer panel. By extending the folded part until it overlaps with the upper plate 10b of the joiner, and by providing a water return 13 in this folded part as necessary, the overlap space between the outer panels is increased, and the joining part is By providing a gap, rainwater is prevented from rising through the polymerization space by capillary action.

Furthermore, for the same reason, the space formed by the end of the folded portion of the outer panel and the rolled joint of the joiner also serves to further prevent rainwater from penetrating.

(b) There is no space between the wind-resistant outer panel and the base plate 8, and the folded parts 12 and seams 15 of the outer panel increase the molding rigidity of the flap 14, and the plate surface does not bulge or bend. The outer panels 7A to 7C do not become bulky due to hardness or other reasons, and furthermore, the tips of the folded portions 12 are fixed to the joiner 1.
Since it is wrapped around the top plate 10b of 0, the bonding strength between the outer plate, the base plate, and the joiner is high, and the wind resistance of the outer plate is extremely high.

(e) Sound insulation As mentioned above, since there is no space between the outer panel and the base panel 8, external noise does not escape and rain noise does not resonate in the attic, furthermore, the acoustic effect is important. In the case of a building where the outer panel and base board 8 are in close contact with each other,
It is easy to separately install a sound insulating plate between both members.

(d) The external appearance is based on a rectangular well-aligned shape, and the thickness of the brim and the depth of the stepped drop give it a sense of shading and solidity, giving it a luxurious overall appearance.

(e) Equipability Since the outer panel is fixed to a structure such as rafters 9 through a joiner, it can be easily attached to the exterior or interior walls of a building. Needless to say, it can be mounted directly on the wall.

(f) Productivity and workability Production can be automated by standardizing the outer panels.
Productivity and construction efficiency are easy to achieve.

In addition, for the structure of the continuous part between the side edges of each outer panel, and the structure of the upper and lower ends of the top and bottom outer panels, known structures related to gutters and other attached mechanisms can be used. It is.

Furthermore, the unevenness 11 may be omitted if necessary.

As described above, according to the exterior structure according to the present invention, a head is provided between the base plates of each tier by the above-mentioned joiner, and the upper surface of each base plate on the outer surface of the joiner is covered with a metal outer plate. , a double collar with a hook-shaped cross section is formed at the upper end of the lower outer plate, and the upstream end of the folded part is fixed by wrapping around the upper end of the joiner,
The structure is such that the brim of the lower outer panel is secured by seaming with the edge of the lower edge of the upper outer panel, resulting in an exterior structure with excellent waterproofness, wind resistance, sound insulation, ease of installation, production workability, and appearance. Not only is it effective for general buildings such as theaters and halls, it is also useful not only for the exterior of roofs but also for the interior and exterior of buildings in general. It has the effect of increasing ease of use, ease of use, and availability.
