Description

The present invention relates to a rain closing structure for a roof on which a projection such as a chimney is loaded.
In particular, we propose a new structure for flushing (rain-breaking member, rain-shielding plate or shut-off skirt) by installing a clean burn chimney of a wood-burning stove through the roof.

  The technology to completely prevent rainwater (liquid), dew, and moisture from entering (flooding) in the roof's rain closing structure is based on the technical level of complete waterproofing unless it is a method of constructing the entire roof with a single member. It is difficult to achieve, and in particular, a supporting device and waterproofing in a structure where a double-stacked chimney of wood-burning stove and a relatively heavy chimney with a stack stack top etc. on the chimney are provided in the middle of the roof Is said to be exceptionally difficult.

  Rather than providing a chimney and other projections for the roof structure at the design stage, it is increased to a rainy structure for a later-installed roof in which a hole is provided in the completed roof and a projection such as a chimney is attached and loaded. When it comes to renovation, it becomes a more difficult structure and work.

  In the conventional rain structure of the roof when loading protrusions, when a large amount of rainwater (liquid mist) pours into the roof and contacts (pours) the member during a certain period of time, such as during heavy rain or typhoon, Due to the looseness of the members and wind and rain pressure, rainwater (liquid) could not be completely waterproofed, and some of the water soaked into the house (inundation).

  For example, in the publication of Japanese Utility Model Publication No. 56-105026, the contact portion between the rainwater umbrella and the rainwater partition plate is one point (one place) in a circular shape with the chimney, and the waterproof portion is the portion, the chimney, and the heat resistance. It can be confirmed from this document that there are only two points of the packing and the fastening screw portion.

Published Utility Model Gazette No. 56-105026

However, in the case of the public utility model publication No. 56-105026, the contact portion between the rainwater umbrella and the rainwater partition plate is one point (one place) in a circular shape with the chimney,
When used in the double chimney flushing, which is indispensable for the latest wood burning stove aiming at clean burn, there was much room for improvement due to the strength and waterproofness of the components.
Incidentally, in the contact portion of the above-mentioned document, the reinforcing content such as welding connection is not performed.

  Further, in the case of the published utility model publication No. 56-105026, there still remains a problem that a complicated structure and costly parts such as a fastening piece, a fastening screw and a heat-resistant packing are required.

The problems to be solved concerning the rain closing structure of the roof are as follows.
(1) Increase the waterproofing point and make sure that it prevents rainwater, mist-like water droplets, etc. from entering the house.
(2) The structure should be such that the construction, connection, engagement, and pressure welding between each member of the present invention and the roof member can be easily performed even in the front-end construction and the back-end construction.
(3) By making the structure so as not to become complicated when performing construction work, it shall be easy to standardize by standardizing the construction.
(4) The structure can be provided at a low price as a structure in which the number of members is reduced and the processing is not complicated.

  The main object of the present invention is to provide a roof rain closing structure that is excellent in waterproofing and has a projection such as a chimney attached to the roof.

  Here, the present invention is a rain closing structure using a blocking plate for waterproofing a mounting hole when an indoor penetration such as a chimney is mounted on a roof, and has a hole for mounting the chimney etc. in a substantially rectangular shape in plan view. A clogging plate provided with a cylindrical portion and a double side of the refraction edge, leaving one side (lower side) and standing up, and a water absorbing material ridge provided between the double refraction edges, and a refraction inside the clogging plate A rain closing structure is proposed in which the refracting edge of the roof member is combined with the edge in a substantially Z shape.

The inner refracting edge is formed by welding a substantially side surface strip member to the surface of the closing plate.
The outer refracting edge of the closing plate has a substantially side ridge shape that is raised to the front side and inclined and bent inward.
The refracting edge can be manufactured by bending.

The water absorbing material ridges are laid at a small interval between the outer refractive edge and the inner refractive edge of the closing plate.
The water-absorbing material ridges are arranged in a row on the left and right sides in a plan view, but can be provided in two rows on the left and right sides if the distance between the inner and outer refractive edges is increased for some reason.
The water absorbent ridge is a material that maintains sufficient water absorption even when deformed by being pressed between the roof member and the closing plate.
The water-absorbing material ridges are pressed between the roof member and the closing plate, the upper surface is in contact with the roofing material, and the lower surface is in contact with the closing plate.
It is preferable that an adhesive layer is formed on the lower surface for adhesion.
The shape is a thick tape shape or a square bar shape, and a shape having a thin and tapered shape at the square bar tip is also proposed. This is in order to increase the efficiency of water droplet spraying at lower places.

In order to solve the object and the problems, the present invention has the above-described configuration and has the following technical effects.
a: In addition to the roof member and the inner refracting edge being combined in a substantially Z shape, there is a water-absorbing material and a folded structure (outer refracting edge) at the back, which enhances the waterproofness of the roof.
b: Construction work can be easily performed because the main members of the rain-finished structure have a simple structure that can be factory-produced.
c: Engagement pressure contact (construction, dismantling) with an existing roof member is easy.
d: Refractive edges of the roof member and the blocking plate were combined in a Z shape to make them engageable and difficult to peel off. In this engaging and press-contacting operation, the water absorbing material is firmly arranged at the same time, and there is work economy.
e: Since each member has a simple configuration, it can be mass-produced inexpensively without requiring a complicated process in the manufacturing process.

  Even if the waterproof part is provided in multiple layers (double or triple), even if it passes through the waterproof line that comes into contact with water first, the next waterproof line can surely prevent water from entering, Water resistance is significantly improved compared to conventional technologies.

  Another problem is that the construction work when installing the rain closing structure of the present invention on the roof from the beginning of the development is easy to proceed, and the installation of a blocking plate, draining strips, and water absorbent ridges The structure is such that can be easily performed.

The water-absorbing material is a sponge or the like of a convex strip (a long strip with a height) and is light, and even when it is disposed long, there is little burden on the roof member, and it does not cause anxiety about the weight.
In addition, the water-absorbing material is disposed in the shape of a bowl or П on an inclined surface, so that a small amount of absorbed water is efficiently discharged and dried.

One end of a roof member such as an iron plate (steel plate fired) forms a refracted edge refracted at an acute angle on the lower side, and the shape of a part of the engagement point with the end face hook-shaped ridge member (refractive edge) is changed to a Z shape. Each is formed in a refractive shape so as to be combined.
The roof member refracting edge and the ridge member refracting edge form a substantially flat surface once they are engaged and pressed into a Z shape, so they will not peel off even when subjected to strong winds, etc. Exhibits sufficient waterproofness against rainwater.

The closing plate constituting the present invention is mainly processed by welding the cylindrical portion and the inner refractive edge and forming the outer refractive edge, and thus can be mass-produced inexpensively without requiring a complicated process in the manufacturing process. .

The best mode for carrying out the present invention will be described.
As shown in the figure, it is a rain closing structure using a blocking plate (1) for waterproofing the mounting hole when a penetrating object such as a chimney (5) is installed on the roof, leaving one side (lower side). A closing plate (1) having a water-absorbing material ridge (3) provided between the double refracting edges (12) and (2); A rainy structure in which the refractive edge (2) on the inner side of the closing plate (1) is combined with the refractive edge (61) of the roof member (6) in a substantially Z shape is a basic form.

The angle, width, and length of the internal angle from the horizontal plane to the refractive edge of the refracting edges (2) and (12) provided on the closing plate (1) of the present invention are set according to the roof and its members. It is necessary to set the width and length relative to the construction site member.
The refracting edge (2) and the refracting edge (61) are engaged and pressed against each other, and the refracting edge (12) is pressed against the back surface of the roof member.

The components such as the closing plate (1) and the refractive edge (2) of the present invention are made of stainless steel. It is more durable than the iron plate roof member (6).
In addition, a metal plate such as a stainless alloy plate or a hard synthetic resin plate can be used. The material is not limited, but a suitable durable material is selected.
The water absorbing material ridge (3) of the present invention is a water absorbing material formed in a tape shape having a height. It is a long and thick ridge. In terms of construction, it is preferable to form an adhesive layer (weather resistance) on the bottom surface.

In the construction, the water absorbing material ridge (3) is pressed and clamped between the closing plate (1) and the roof member (6), so that it is a flexible material that can be deformed and the water absorbing performance does not extremely decrease. .
The water-absorbing material protrusion (3) is a flexible elastic material having a large number of foamed holes, and a tape-like sponge or the like can be used.
Other water-absorbing materials may be materials such as silica porous material, PVA sponge, porous wood, ceramic porous material, and nonwoven fabric.
If it has a certain thickness and width and can be constructed without moving the position, the adhesive layer is not necessarily provided.

The obstruction plate (1) is provided with a cylindrical portion (4) on the inclined flat surface (11) and releases the lower side (the direction in which the water droplets flow down). In the case of a triangle, a refraction edge (12) refracted on the front side is provided on the left and right sides in the case of a triangle.
The shape is not limited as long as it can be engaged and connected to a roof member (6) described later, and may include a shape including a partially elliptical portion.

The refracting edge (12) is a refracted edge located on the outer side (outer periphery) of the closing plate (1).
Further, the rib member (2) is welded to the surface of the closing plate (1) in parallel with the outer refractive edge (12) at a small interval so as to be the inner refractive edge (2).
Since the strip member (2) to be the refracting edge (2) is made as a separate part and welded, the flow path (10) is formed as a space in the gap between the refracting edge (2) and the refracting edge (12). It can be formed with an arbitrary width.
A water absorbing material ridge (3) is provided between the double refracting edges (12) and (2). The water absorbent ridge (3) is usually joined near the middle of the gap.

The refractive edges (2) and (12) and the water absorbing material ridge (3) have the same height or the dimensions of the water absorbing material ridge (3) are high. Since the roof member (6) covering the water absorbent material ridge (3) is pressed flatly, the double refracting edges (12) and (2) flatten the roof member (6) together with the water absorbent material ridge (3). To support.
The lower side of the closing plate (1) is installed so as to cover the lower roof member (6) connected to it. With this configuration, rainwater does not stay on the lower side.
The periphery of the closing plate (1) does not actually cause unevenness by crimping, but forms a flat and inclined roof slope that is substantially the same as the surroundings.

Even if the obstruction plate (1) is installed on an inclined roof and rainwater drops invade it, there is a refraction edge (2) (12) for draining water, and it will initially become a refraction edge (2) as an inundation path. It can be inferred that it enters the interior of the water-absorbing material ridge beyond the strip member (2), but even in that case, the water-absorbing material ridge (3) absorbs water and does not penetrate into the house, and the inclined surface is not Since there is a refracting edge (12) for drainage and further drainage, it is unlikely that water drops will enter.

By the way, when carrying out the test of the rain performance structure of the present invention, even in a long heavy rain environment, there are almost no water droplets exceeding the inner refracting edge (2), and an extremely fine mist is formed in the inner flow path (10). Although there was only generation | occurrence | production, since there existed a water absorbing material protrusion (3) in that case, it did not reach the adjacent flow-path (10) space.

The water-absorbing material ridge (3) forms a flow path (10) in a space where the water-refracting edges (2) and (12) are doubled and the two refractive edges (2) and (12) surround it. Since it is divided, the waterproofness is double and triple, which is extremely high.
In this way, the water absorbing material ridges (3) are provided in the gaps between the refraction edges (2) and (12) to form the flow path (10) and to limit the flow path even if water drops should enter. This makes it easier to discharge rainwater and enhances the effect of preventing water intrusion.

One example of how to proceed with the post-installation work is to first provide holes in the existing roof base plate (62), and provide holes in the roof member (6) that are equal to or greater than the holes in the base plate (62).
Refractive edge where the horizontal plane (21) and the inclined surface (22) are adjusted by adjusting the position so as to engage with the cylindrical part (4) having a hole for fixing the chimney (5) and the roof member refractive edge (61). (2) is spot-welded, the water-absorbing material ridges (3) are laid, and the closing plate (1) provided with a refractive edge (12) on the outside is installed.

The roof member (6) located around the closing plate (1) is refracted at its end to form a refractive edge (61) of the roof member.
The roof member (6) is bent into an inverted bowl shape at the end, and is engaged with the inner refractive edge (2), which is a side surface ridge member fixed to the closing plate (1), in a substantially Z shape. (6) and the obstruction | occlusion board (1) become a structure which presses a water absorbing material protrusion (3) inside the space which forms, and forms an inclined flow path (10) inside.

Although depending on the size of the closing plate (1), the usual process in the case of retrofitting is to remove one or two roof members of a predetermined size and refract the remaining roof member (6). The edge (61) is used to engage the inclined surface (22) of the refractive edge (2) of the closing plate (1).
The chimney (5) and the cylinder (4) are welded in a watertight manner, but the work can be carried out at the site or in advance in the factory depending on the circumstances.
As described above, the post-installation work of the rain closing structure according to the present invention is a drilling work performed on the site and the installation of the closing plate (1), so that it can be performed very easily and quickly.

If the angle of the inclined surfaces of the refraction edges (2), (12), and (61) is matched in advance after the roof drilling work, the closing plate (1) is inserted from below and the refraction edges (2 ) And the refracting edge (61) of the roof member (6) are closely aligned and engaged, and the lower part is processed to attach the chimney (5), so that the workability is further improved.
