Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses an extrusion molded product made of a ceramic inorganic material such as Cera'z 17x as a roof ridge structure, more specifically as a ridge structural member. This project concerns a new type of roof ridge structure that is different in terms of function and design from the conventional roof ridge structures made of tiles and metal.

[Conventional technology]

As roof ridge structures, structures using tiles have been known for a long time, and on the other hand, as materials other than tiles, many metal ridge structures developed for metal roofs are known. Conventional ridge structures for metal M roots involve fixing a pair of ridge supports on the roof on both the left and right sides of the ridge pole, and installing the ridge members straddling these ridge supports. The basic structure as shown in FIG.

[Problem to be solved by the invention]

Of course, metal roofs are advantageous in that they are easier to construct and lighter than tiled roofs, but it is an undeniable fact that they are inferior to tiled roofs in terms of corrosion resistance. Therefore, it is clear that the conventional metal ridge structure described above similarly has problems in terms of durability. In addition, since the metal ridge structure consists of a ridge support material and a ridge material that have a cross section similar to that of an aluminum profile, the cross section of the locking hook of each member is small, and therefore the engagement by the locking hook is difficult. However, there is a problem in terms of strength, and each member must be fixed to each other using fixing means such as screws, rivets, caulking, or other auxiliary fixing pieces so that they do not come out of their retaining relationship. Therefore, with a metal ridge structure, the construction is complicated due to fixing the ridge supporting material and the ridge material using fixing means other than their respective locking hooks, and the provision of these fixing means has a long-term impact. The problem was that rainwater treatment was not always appropriate in the case of rainwater.

[Means to solve the problem]

In order to solve the above-mentioned problems with the conventional metal ridge structure, the present invention has developed a ceramic roof tile that has the same durability as clay roof tiles.
A long ridge support material and ridge material with a predetermined cross section are extruded or shaped using a ceramic inorganic material such as S7, and both members are easily and securely engaged only by securing their respective locking hooks. The aim is to provide a roof ridge structure that can be fixed easily.

As a specific means for that purpose, the present invention provides a pair of elongated plate-shaped ridge supporting materials extruded and shaped using an inorganic material such as seratonox, and a pair of long plate-shaped ridge supporting materials on these ridge supporting materials. It consists of a combination of a long ridge member of the same quality that is installed across the ridge, and the ridge support member has a locking hook having an S-shaped curved surface in which the upper end of a rising piece protruding from the upper edge is bent toward the lower edge side. and a water return surface on the lower edge side wall surface of the thick part whose wall thickness is gradually increased by an upwardly inclined surface from the lower part of the rising piece to the center of the surface, and the said ridge support is provided on the back side of both sides of the ridge material. A locking hook having an S-shaped curved surface that corresponds to the locking hook of the material, and a hollow part for open sealing that corresponds to the water return surface of the ridge support material in the thick part on the back side of the locking hook. It is characterized by the fact that

Furthermore, the roof ridge structure according to claim 3 basically consists of a combination of the ridge support material and the ridge material shown in claim 1, and the upper surface of the ridge material has internally provided along the length direction. The thick part has a ridge-shaped thick part with a plurality of pores, and inside this thick part, there are a plurality of ventilation holes bored perpendicularly to the pores along the slope of the ridge material, and The ridge material is characterized by having a ventilation hole bored from the back side of the ridge material so as to communicate with the pores in the thick portion.

[Effect]

In the roof ridge structure according to the present invention, the ridge material is inserted from the end direction of the ridge into both ridge support materials fixed in advance on the left and right sides of the ridge so that the locking hooks of the upper and lower art materials engage with each other. Just by doing this, the bonding between the ridge support material and the ridge material is ensured.

The locking hook of the rising piece provided on the upper edge of the ridge support material and the locking hook provided on the back side of the ridge material are both shaped to have corresponding S-shaped curved surfaces, so that the upper and lower locking In the state where the locking hooks are engaged, the contact angle between the engaging surfaces of both locking hooks can be freely varied with a relatively small gap. Therefore, the left and right slope angles of the ridge materials are set to 1/2 and 1/2 in advance.
If the angle is set so that it can be applied to any of the three slope roofs, even if the ridge support is installed on a 1/2 or 1/3 slope W root, each member can be attached to the upper and lower locking hooks. Due to the rotational contact of the S-shaped curved surface, it is possible to engage without force through both locking hooks.

On the other hand, on the back side of the locking hook of the ridge material, there is an open seal cavity at the upper position corresponding to the water return surface provided in the center of the surface of the ridge support material, so rainwater can be absorbed into the ridge support. When rainwater is blown up from below along the surface of the material, it is returned to the bottom by the water return surface, but when the rainwater overcomes this water return surface, the rain ice is forced into the cavity above. After that, the rainwater is returned to the front part of the water return surface by the internal air pressure, and it is possible to prevent rainwater from overcoming the water return surface and directly penetrating toward the upper and lower locking hook contact surfaces.

Next, an embodiment of the ridge structure according to the present invention shown in the drawings will be described.
