Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mento door that significantly prevents rainwater from entering and allows easy drainage of rainwater once it has entered.

[Conventional technology and its problems]

Conventionally, when repairing the above-water side of a folded-plate roof, a mento was inserted between the below-water side of a ridge cover or wall joint, etc., and the valley of the folded-plate roof. Normally, there is a small gap between the periphery of most of the doorways and the valley of the folded plate roof, which can prevent rainwater from entering to some extent in cases of low rainfall and weak rain. However, during strong winds and rain, a large amount of rainwater infiltrates through the gaps.

Furthermore, if the area around the door is substantially sealed with a sealant or the like, there is a problem that the rainwater that has entered the door will not be drained away, but instead will accumulate inside the door. However, there were also problems such as early corrosion due to this accumulated rainwater.

[Means for solving the problems] Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention by forming an opening at the bottom of the main plate of the inverted trapezoidal door. The opening is surrounded by a weir-like plate, and a weir-like cut-off part is provided on the main door plate with a small space between the main door plate and the weir-like plate, making it possible to drain rainwater. This method solves the above-mentioned problems by making it extremely difficult for rainwater to infiltrate and making it possible to easily drain rainwater once it has infiltrated.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 9.

A is a side door of the present invention, and an opening 1a is formed in the lower part of a side door main plate 1 having a substantially inverted trapezoidal shape.
The main door plate 1 is formed to have a shape substantially equivalent to the cross section of a valley portion 3a of a roof plate 3 of a folded plate roof B, which will be described later. The opening 1a is formed in a substantially rectangular shape at the lower part of the main door plate 1. In addition, as shown in FIGS. 6 and 7, there is also one in which a cut is made in the center of the lower part of the main door plate 1, and the cut portion is bent so that the cross section is V-shaped.

At the upper end of the door main plate 1, an upper part 1b is bent on the surface side (the surface facing below the water when attached to the folded plate roof B). A protrusion 1c that bulges upward along the longitudinal direction is formed on the upper portion 1b (see FIGS. 1, 5, and 6).

Reference numeral 2 denotes a weir-like blocking portion, in which a mounting portion 2b is integrally formed from the upper end of a weir-like plate 2a (see FIGS. 5 and 6). The weir-like flat plate 2a is formed into a flat plate shape (see FIG. 5) or a curved shape (see FIG. 6). The mounting portion 2b is formed as a horizontal portion by bending the upper end side of the weir-like plate 2a, and the mounting portion 2b is bent upward from the end of the horizontal portion (see FIGS. 5 and 6). Further, the weir-like plate 2a, the horizontal portion, and the attachment portion 2b form a substantially Z-shaped cross section. The weir-like plate 2a of the weir-like blocking part 2 surrounds the opening 1a of the main door plate 1, and is mounted with a small space between the main door plate 1 and the weir-like plate 2a. The portion 2b is fixed to the main door plate 1.
Here, the width of the weir-like plate 2a is preferably wider than the width of the opening 1a (see FIG. 4).

In addition, as shown in Fig. 8, only the lower center of the main door plate 1 is bent on the back side of the main door plate 1 (the side facing the water side when attached to the folded plate roof B). In some cases, the weir-like plate 2a is formed integrally with the main door plate 1 with a slight distance therebetween. In this case, the lower end of the door main plate 1 and the lower end of the weir-like plate 2a are configured to be located on the same horizontal plane.

Further, the weir-like blocking portion 2 may be attached to the front surface side of the main door plate 1.

B is a folded plate roof, and the roof plate 3 constituting this has peaks 3b, 3b integrally formed on both sides of a valley 3a, which are made of a metal plate of an appropriate length or length in the longitudinal direction. It is formed. If the bottom of the valley portion 3a is wide, the intermediate mountain portion 3c may be
A bulge is formed (see Figure 9). In the folded plate roof B, the mountain part 3b on one side of the roof sheet 3 is placed on the roof bracket 4, and the mountain part 3b of the adjacent roof sheet 3 is overlapped on the mountain part 3b of the roof sheet 3. The peak portions 3b, 3b and the roof bracket 4 are fixed to drill screws, bolts, nuts, etc., and these steps are repeated in order to construct the folded plate roof B.

If the above-water side is configured as a ridge, the ridge bracket 5 is placed and fixed on the roof holder 4, as shown in FIGS. The mountain portion 3b is placed on the ridge support fitting 5 and fixed with a drill screw or the like.

Further, as shown in FIG. 3, a wall portion C may be provided at the upper end of the folded plate roof B on the water side.

As shown in FIGS. 1 to 3, etc., a stop door 6 is fixed to the water-side upper end of the valley 3a of the roof board 3 in a watertight manner, or the height of the valley 3a of the roof board 3 is If it is low, as shown in Figure 9, the valley 3
An end rising portion 3d is bent and formed at the upper end on the water side of a. In order to form the end rising portion 3d, both sides of the valley portion 3a are bent in a 800-degree direction.

7 is a long metal draining material, and there are two types: a ridge-wrapping type (see Figures 1 and 2) and a wall-mounting type (see Figure 3).
The gently inclined parts 7a, 7a are formed symmetrically, forming a chevron-shaped part having a substantially F-shaped cross section, and folded edges 7b, 7b are formed below both ends of the chevron-shaped part. A protrusion 7c, which engages with the protrusion 1c, is bent and formed on the folded edges 7b, 7b.

Further, in the wall-mounted type, a vertical rising portion 7e is bent on one side of the upper surface portion 7d, and a folded edge 7b is formed on the other side (see FIG. 3). At this time, a protrusion 7c is also formed in a bent manner on the folded edge 7b.

First, the upper part 1b of the mendo A of the present invention is
The gently sloped part 7a and the folded edge 7b (or the upper surface part 7
d and the folded edge 7b), the ridges 1c and 7c overlap, and the side door A is fixed to the draining material 7. Next, the side door A is inserted into the valley part 3a of the roof plate 3 of the folded plate roof B, and the side door A
A sealing material or the like is filled as necessary around the roof plate 3, and a drainage material 7 such as a ridge wrapper or wall joint is placed at the ridge part or the joint part between the wall part C and the folded plate roof B. It is fixed to the peak part 3b using a fixing tool such as a drill screw or a bolt/nut.

In the figure, 8 is a structural member such as a purlin beam, and 9 is a watertight rubber plate for a spacer.

[Effect of idea]

In the present invention, an opening 1a is formed at the lower part of the main door plate 1 having an inverted trapezoidal shape, and this opening 1a is surrounded by a weir-like plate 2a, and between the main door plate 1 and the weir-like plate 2a. By providing the door with weir-like blocking parts 2 on the main plate 1 of the door with a slight interval, first of all, it is extremely difficult for rainwater to enter, and once the rainwater has entered, it can be easily drained. Secondly, it is possible to prevent foreign matter from entering the inside of the door while forming the opening 1a, and thirdly, it has a simple structure and can be manufactured easily, and can be provided at an extremely low price. It has various effects.

To explain these effects in detail, the mendo A of the present invention has an opening 1a formed at the lower part of the main door plate 1, so by providing the mento A on the folded plate roof B, the folded plate roof can be improved. Even if rainwater enters from around the valley 3a of B and the area around the door A, this infiltrated rainwater is drained from the opening 1.
Water can be drained without interruption from a. moreover,
Since the weir-like plate 2a surrounds the opening 1a and is provided at a small distance from the main plate 1 of the door A, the opening 1a of the door A is
The weir-like plate 2a blocks rainwater flowing into the opening 1a, thereby preventing rainwater from entering through the opening 1a. That is, the opening 1a makes it extremely difficult for rainwater to enter, and allows for easy drainage of rainwater once it has entered. Therefore, in the case of strong winds and rain, with conventional mendo,
Rainwater that has entered through the gap between the folded plate roof and the area around the door is not drained from the gap due to the wind pressure on the outside of the door, and instead accumulates inside the door, causing rain to leak indoors. However, the present invention can solve these problems.

Next, the weir-like plate 2a is attached to the opening 1 of the main door plate 1.
Since it is provided surrounding a, it prevents foreign objects such as pebbles and leaves swept away by the wind from entering the inside of the door, which has the advantage of preventing staining of the folded plate roof. There is.

Next, the men door A of the present invention is composed only of the main door plate 1 and the weir-like blocking part 2, and the weir-like blocking part 2 also has an extremely simple structure, can be easily manufactured, and has an extremely low cost. price can be provided.
