Description

[Detailed Description of the Invention] (+?Field of Application of Industry) This invention relates to a horizontal roofing board made of metal steel plate, and more specifically, the baking for rust prevention is done by applying a predetermined +1'l coating or the like. In the horizontal roofing plate, in which eave side 1 ridge side engaging portions having a predetermined cross-sectional shape for engagement are formed in advance on both ends of a long metal steel plate, in particular, the eave side 9 Building side phase U
This invention relates to improvements in the shapes of each of the engaging portions and the supporting portion.

[Conventional technology]

Conventionally, many types and configurations of horizontal roof panels made of long metal steel plates of this type have been proposed.

The shape and configuration of the combined engagement part intended to prevent rain water from entering the engagement part of the eaves side from the engagement part of the first building side, etc. Research and development is active.

Here, conventional examples of connections and support shapes at the engagement portions of the nine eaves sides that are generally adopted in horizontal roof panels made of long metal steel plates are shown in Fig. 10 and Fig. 10. 1st
FIG. 1 shows the effects of wind and rain pressure on the connecting and engaging portions and supporting portions, and the effects of fourfold loads due to snow accumulation, etc., are shown in FIG. 12.

FIG. 1θ is a cross-sectional perspective view showing a conventional horizontal roof plate, FIG. 11 is a vertical cross-sectional view of the same roof structure in a state where it is covered, and FIG. 12 is an explanatory view of the same operation.

In these conventional examples shown in Fig. 1O and Fig. 11, the horizontal roofing board (1) is made of a long metal steel plate of a predetermined unit length, for example, with a predetermined r.f. A fully bent steel plate is formed using a roll forming machine or the like, leaving a face plate part (2) in the center along the long hair direction, forming an eave side forming part (3) on the - side of the plate, and forming a ridge side on the other side. 'if! (4) are formed by continuously molding each of them.

Therefore, the eave side molded part (3) includes the face plate part (2).
Bend the crown (5) slightly diagonally outward and downward at a predetermined length from the lateral side of (7) is bent inward to form an engaging piece (8), and its end edge is formed into a bent portion (9).

In addition, in the ridge side molded part (4), in addition to the face plate part (2), a holding part (lO) is folded inward from the 011811 side so as to hold the edge bent part (9). At the same time, bend the tip outward again to form a folded part (11).
Then, the protruding part (12) is raised upwards, and then the protruding part (12) is gently tilted downward to extend the part (13) flatly, and the terminal part (14) is slightly raised. It's a lie.

In this conventional example, the roof assembly on the building side is mounted on the rafters (15), and the horizontal roof plate (1) on the front side (eaves side) is first attached. The inner space is filled with wood wool board (as a back-up material).
16), etc., and the installation is done with the part (13) interposed.
) to fix the installation as appropriate, and then attach the horizontal roof that will be the next stage (ridge side) to the ridge side molding part (4) of the horizontal roof board (1) on the previous stage side. The eave side molded part (3) of the board (1) is engaged and connected, and this roof L-edge engagement assembly is repeated sequentially from the eave side to the ridge side, that is, from the bottom to the top, to achieve the desired result. The horizontal roof structure is constructed with thatched roofs.

That is, more specifically, the front ridge side molding part (4)
The edge bending part (9) including the engagement piece part (8) is inserted into and engaged with the holding part (10) so that the next eave side molded part (3) is fitted into the end edge. Fold back the inner surface of part (6) (
11), and in this engaged and connected state, the engaging piece part (8) and the edge bending part (9) are held in the holding part (10). At the same time, the lower edge (7) of the edge portion (6) is in line contact with the surface of the face plate portion (2), and the protruding edge of the folded portion (11) is in line contact with the inner surface of the edge portion (8), Roughly, the protrusion (12) is located at the lower part of the inside of the crown part (5), and the terminal end part (14) is located at the lower part of the inside of the face plate part (2).

Therefore, in the case of this conventional structure, the concept of the engagement connection part and the support part in the horizontal roof structure is different from each other, as is clear from the above-mentioned structures. The lower edge (7) is brought into line contact with the surface of the face plate part (2), and the line contact part, that is, the front ridge side molding part (0 and the next eave side molding part) of the horizontal roof board (1) is The engaging joint edge part (1) with the part (3)
8) to prevent rainwater from entering 11-, and the holding part (11-)
0) Inward engagement piece i'? Edge bend (9) including R (8)
Based on the insertion, engagement and holding of the
This is due to the fact that the gap between 2) and the end portion (14) provides a so-called water return effect.

[Problem that the invention seeks to solve]

However, in the case of a conventional horizontal roof structure made of metal steel plates constructed in this way, the influence of wind and rain pressure on the engagement joints, as well as the influence of wind and rain pressure on the engagement joints, as described below. There is a serious problem with 33% of the load such as snow accumulation on the face plate.

In other words, regarding the influence of wind and rain pressure on the engagement connection part of the IIF person, the engagement joint edge part (17) between the front ridge side molding part (4) and the next stage eave side molding part (3) is 2) is located at the corner of the inner corner where the lower edge (7) of Naturally, the wind and rain blowing up along the roof slope of section (2) concentrates in the vicinity of the engaging joint edge (17) exposed at the corner of this inner corner and blows away strongly. , and the end edge (G) heals and bounces upward, so that the wind and rain pressure (18) directly blows against this engaging joint edge (17).
The wind and rain pressure (19) that bounces in the L direction and the combined pressure (20) of both of these wind and rain pressures act.

In this case, on the one hand, the wind and rain pressure (18) may cause water to enter the structure from the engaging joint edge (17) due to capillary action, and on the other hand, the wind The first pressure (19) and the combined pressure (20) cause the edge (6) to float upward, and the interlocking joint edge (+7) is pushed open, causing further flooding. , and powerful wind and rain.

Since most of these are usually accompanied by sand, mud, and other dust, these impurities can enter the interior of the structure and cause rust and corrosion, and later these rust and corrosive components can be exposed to the outside. In addition to spilling out and staining the roof surface, especially in cold regions, 141
When water is retained in these impurities, it freezes and expands as the temperature drops, impeding the engagement of J1, and also causing the holding part (LO ), the edge bending part (9) including the engagement piece frB(8) abuts and engages with the flange of the folded part (11), and the edge part (
Since 6) is performed together with the inner impact,
If there is a difference in length between the engaging piece (8) and the folded-back part (11), for example, the engaging piece (8)
If the sides are long, the inner surface of the end edge (6) cannot abut against the protruding edge of the folded part (11);
) side is longer, the engagement piece (8) will fit into the holding part (10).
) There was a risk that the abutting engagement and holding of the bent edge portion (9) including the portion (9) would be hindered.

In addition, regarding the influence of the load on the latter engagement connection part and the face plate-A, the load on the entire surface due to snow accumulation, etc.

or partial loads caused by trampling by repair workers, etc.
In other words, it prevents deformation when load pressure (21) is applied.
- A wooden board (16
), but in such a stage,
The supporting strength against the load, in other words, the resistance force, is not sufficient, and the horizontal roof plate (1) itself, that is, the face plate (2) including the engagement connection part, is easily deformed, and similarly, the intended engagement is not achieved. In addition to inhibiting the mating mode, the presence of wood wool plates (16) [1
Regarding the body, it also had the disadvantage of unnecessarily complicating the structure.

The influence of wind and rain pressure on the engagement joint edge of the ridge side molding part and the next stage eave side molding part, and the influence of load transfer on the engagement joint part and the face plate H can be respectively eliminated, In addition, it is an object of the present invention to provide a horizontal IT roof board whose configuration itself is as simple as possible.

[Means for solving problems]

In order to achieve the above object, the horizontal roof board according to the present invention has a face plate part formed in the longitudinal center of a long metal steel plate, and molded parts on each side of the eaves and one ridge are formed on both sides of this face plate part. In a horizontal roof board, which forms a horizontal roof by engaging and connecting the eave side molding part on the previous stage with the ridge side molding part on the next stage side,
The eave side molded part includes a crown part disposed at the end of the face plate part, an edge part raised from the crown part, and an engaging piece part in which the lower end of the edge part is bent inward. Let it form and again 1i?
In the molding part on the i-marking side, there is a tL11 raised from the face plate part.
a holding part in which the L end of the standing part is folded back and bent outward to engage and hold the engaging piece part; a ficl part in which the holding part is folded back outward again; An attachment part is formed by lowering the crown support part and extending it flatly, and a face plate support part is formed by raising the attachment part and bending it anew to abut against the inner surface of the face plate part.

[For production]

That is, in this invention, the abutting portion between the lower edge of the rising part of the one eave-side molded part and the lower end edge of the edge of the ridge-side molded part is exposed to the outside at a position rising from the face plate part. Because of this, it is easy to avoid wind and rain concentrating on this abutting part, and only the engaging piece part of the eave side molding part is engaged and held by the holding part of the ridge side molding part. Because of this, the engagement and holding by this surface contact is perfect, and in conjunction with the arrangement of the abutting portion at a position standing from the face plate, it prevents the intrusion of rainwater, sand, mud, and other dust. In addition, since the inner surface of the crown of the head and the inner surface of the face plate are supported against the crown support and the face plate support, the supporting force against the quadruple load and the structure are improved. The overall strength can be significantly increased.
