Description

  The present invention relates to a ridge ventilation device installed at a ridge portion of a roof, and in particular, a ridge that can perform good ventilation with excellent rain performance and has a simple structure and can be easily constructed without stepping on a roof tile. It relates to ventilation equipment.

  Conventionally, gable roofs have been widely used in wooden detached houses and wooden buildings such as storehouses. The gable roof is a roof in which two inclined surfaces have a mountain shape from the top ridge of the roof to the ground. When the plan shape of the building is a quadrangle, the use of a gable roof has the advantage that the roof can be constructed with only two surfaces, so that the construction cost can be reduced and there is less concern about leakage. The gable roof also has the advantage that the risk of collapse of the house due to the weight of snow is small in heavy snowfall areas because it is difficult for snow to accumulate on the roof.

  By the way, in the conventional wooden prefabricated house, airtightness is improved and air conditioning equipment is advanced. And since the roof slope is restrained compared with a gable roof, the dormitory roof is widely used in the urbanized area where it is highly necessary to consider the shading regulation with the adjacent land. However, on the dormitory roof, which is relatively short of ventilation function compared to the gable roof, dew condensation is likely to occur on the roof panel such as field boards. Therefore, when plywood is used for the field board, this dew condensation may require replacement work of the field board on the dormitory roof, and the property value of the building was greatly impaired. . Therefore, financial institutions in charge of housing finance need to maintain the property value of the building that is the secured property during the loan period. It is becoming necessary to maintain the collateral value over a period of 35 years or more.

  Thus, various ventilation devices for roof ridges have been proposed. For example, in Patent Document 1, when a wing wrapping material is placed and fixed on a ventilation ridge member fixed to a ridge portion so as to cover a roof ridge ventilation opening, the ridge bulge portion of the ventilation ridge member is inclined. A ridge ventilation device has been proposed in which a duct-like ventilation gap is formed by the bottom portion and the chevron portion and the bent portion of the wing wrapping material so that air can be circulated. However, this building ventilation system is not applied to roof construction using pier tiles, but to roof construction using flat roof materials such as slate tiles. The roof structure. In addition, since the wrapping material is placed on the roof plate 2 that is laid on the top of the roof, there is a problem that even if the roof ridge can be ventilated, it is not sufficient for the performance of rain during the rain. .

  Moreover, in patent document 2, it is comprised with the path | route formation member for the ventilation path formation provided with the 1st, 2nd ventilation opening provided between the purlin support means provided with the ventilation opening, the purlin, and this purlin and the roof tile. A ridge ventilation system has been proposed. However, because the pier is provided separately from the auxiliary member as a tile residue to fix the tile bottom of the roof tile, the fixing between the stationary roof tile that goes to the top of the roof and the ridge tile is not reliable, and ventilation is an auxiliary member This is a structure that uses the ventilation opening of the purlin and the purlin support member, and there is a problem that the effect of preventing rainwater intrusion by the roof tile is not considered.

  Therefore, Patent Document 3 is a ridge tile support member that supports a ridge tile obtained by laminating tiles along a roof ridge, and has a space that allows air to pass through the roof tile along the top of the roof ridge. A roof tile support member having a long frame main body mounted on the roof has been proposed. And, when the ridge tile is constructed using the ridge tile support member, the roof tile that goes to the top of the roof is hooked on the long frame portion having the step portions provided on both sides of the frame body. As a result, the frame roof that is attached and fixed along the roof ridge is constructed so that the roof tiles that reach the top of the roof are accurately and reliably spread to the predetermined positions on both sides of the roof ridge. It has become.

On the other hand, as described above, in order to prevent the occurrence of condensation on the field board, the effective ceiling area of the ventilation building is usually calculated based on, for example, the flat 35 (Housing Finance Support Organization) loan standard. According to the loan standard, “the back wall of the eaves or the back of the shed has an air intake hole, and the exhaust hole is provided at the top of the shed as much as possible using an exhaust pipe or other equipment. The ratio of the effective area of the hole to the ceiling area is 1/900 or more, and the ratio of the effective area of the exhaust hole to the ceiling area is 1/600 or more. Is prescribed.
Therefore, the installation of a building support material having an opening with respect to the building is only required to ensure that the ratio of the effective area of the opening to the ceiling area is 1/1600 or more, which is a financing condition based on the current standards of the Housing Finance Support Organization. However, in the structure of the roof tile support member of Patent Document 3, the frame main body is housed in a narrow ventilation space formed between the roof tile and the field plate, so that the effective area of the opening is ensured. The height of the frame body was higher than the height of the tiles.

  Therefore, in the structure of the roof tile support member of Patent Document 3 described above, there is a problem in that the roof tiles and the frame main body are different in height, and thus the cracks of the roof tiles are likely to occur. The roof tile construction work is performed at the top of the high roof, and it is also exposed to the dangers of craftsmen accustomed to high places. In such a situation, when a tread crack occurs in the roof tile, it becomes necessary to transport the alternative roof tile to the construction site, which causes a problem that the construction procedure is significantly delayed.

Therefore, as a result of intensive studies and researches to solve the above-mentioned problems, the inventor has a structure accommodated in a narrow ventilation space formed between the roof tile and the field plate, and prevention of treading of the roof tile or the flat roof tile. Devised a ridge ventilation system that can simultaneously plan.
In other words, the present invention solves the above-described problems, and has a well-ventilated function, can prevent the occurrence of condensation on the field board, and can take measures to prevent inundation inside the roof even in the presence of rain with strong winds. At the same time, it is an object to provide a ridge ventilation device capable of preventing treading cracks during construction.

It is a perspective view of the state which removed the roof tile opposing main-body part in A). FIG. 2 is an enlarged cross-sectional view of the main part of the building for explaining a state in which the building ventilation device of the present invention is applied to the flat roof tile. FIG. 3 is an enlarged cross-sectional view of the main part of the building for explaining a state in which the building ventilation device of the present invention is applied to the Japanese roof tile.

First, the main part of the building, which is the installation location of the building ventilation device, will be described with reference to FIGS. In the case of the flat roof tile shown in FIG. 2, the main part of the building is composed of a base plate 1, a roof tile 2, a roof tile 3, a building core 4, a roof tile 5, and a roof ventilation passage 6. In the case of the Japanese tile shown in FIG. 3, the main part of the ridge is composed of a base plate 1, a tile 2, a tile pier 3, a ridge part core material 4, a roof ventilation passage 6, and funnel tiles 7 a to 7 e. It is composed of a swing tile 8 and plaster 9.
The field board 1 is a base material of a roof material such as a straight or tile, and is a board stretched on a rafter which is a roof structure material. An asphalt waterproof sheet or the like is preferably affixed on the base plate 1 in order to ensure waterproofness. Two types of roof tiles, flat roof tiles and cross roof tiles, are generally used. Flat roof tiles are rectangular Western-style roof tiles, and are a generic term for flat roof tiles that eliminate the wave shapes of mountains and valleys on Japanese roof tiles. The roof tile is a tile with a corrugated cross-section, with a cut in one or two corners.

  The tile pier 3 is a cross member that is struck to the base plate 1 for hooking the tile 2, and is preferably made of a material that has a cross section of, for example, 15 × 30 mm or more and does not easily corrode. When the ridge tile 5 is installed in the ridge portion of the roof, the ridge core material 4 ensures the fixation of the ridge tile 5 and enhances durability against strong winds and heavy rain. For example, as shown in FIG. 2, the ridge core material 4 is fixed to the base plate 1 located on both sides of the ridge with a fixing bracket 4 c made of, for example, stainless steel. Or the ridge part core material 4 is fixed to the purlin provided in the indoor side rather than the field board 1 with the bolt 4b made from stainless steel, for example, as shown, for example in FIG. The purlin (not shown) is attached in parallel with the main building and the girder. When the roof has a roof structure, it is a member at the highest position of the roof structure material.

  The roof tile 5 is a roof tile used for a roof ridge. In the case of a flat roof tile, a flat roof tile 5 is used. The flat roof tile 5 has a simple cross-sectional shape as compared with a Japanese roof tile, because the corrugated roof tiles of the Japanese roof tile are not provided with the wave shapes of the peaks and valleys. The flat roof tile 5 is fixed to the ridge core 4 with, for example, stainless steel bolts 4a.

  On the other hand, when the ridge tile 5 is a Japanese tile, the ridge tile 5 is configured by combining the roof tiles 7a to 7e, the swing tile 8 and the demon tile. The glazed roof tiles 7a to 7e are strip-shaped flat roof tiles used for stacking ridges. The swing tile 8 is a round tile placed on the top of the building. Oni tiles are plate-like tiles that are installed at the edges of Japanese style buildings. Furthermore, in the roof tile 5 for a Japanese-style roof tile, for example, as shown in FIG. 3, plaster 9 is filled corresponding to the wave shape of the mountains and valleys on the roof tile. The plaster 9 is also filled between the roof tiles 7a to 7e, the roof tiles 8 and the wing core material 4 to firmly fix them, thereby improving the durability of the roof, and even in the case of strong winds and storms. , Preventing rainwater from entering the cabin.

  Next, the ridge ventilation device of the present invention will be described with reference to FIG. As shown in FIG. 1, the ridge ventilation device 10 of the present invention includes a roof tile facing main body 11, a field plate abutting portion 20, a ridge side connection portion 30, an eaves side connection portion 40, a tile field plate ventilation passage 50, And the intermediate part shielding member 60 is provided.
