Description

The present invention relates to a snow-proof ventilation ridge structure and a snow-proof ventilation ridge structure provided in a sloping roof ridge of a building such as a house.

In a building such as a house having a sloping roof, the structure of the ridge portion of the sloping roof may be a ventilation ridge structure for ventilation of the back of the hut (see, for example, Patent Document 1). In the ventilation ridge structure as described in Patent Document 1, a slit-shaped opening that communicates with the back of the hut along the ridge of the sloped roof is provided, and the upper part of the opening is formed in a substantially chevron shape with a slope substantially equal to that of the sloped roof. It has a structure covered with a ridge wrapping member. There is a gap between the lower ends on both sides of the ridge wrapping member and the roof surface of the sloped roof, and between the outside and the back of the cabin through the gap, the inner space of the ridge wrapping member, and the opening of the ridge. It is possible to ventilate at.

By the way, there are cases where it is desirable to adopt a ventilation ridge structure even in snowy areas. However, in the ventilation ridge structure, a gap for ventilation is provided between the ridge wrapping member and the roof surface, so in the case of a snowy area, snow blows into the ridge wrapping member from this gap and snow reaches the back of the cabin. There is a risk of intrusion. Therefore, it is necessary to have a ventilation ridge structure that can prevent the intrusion of snow.

In order to prevent such intrusion of snow, in the ventilation ridge structure of Patent Document 1, the ventilation path in the ridge wrapping member from the opening of the ridge to the gap formed between the ridge wrapping member and the roof surfaces on both sides. A porous body is provided on each of them. This porous body is formed in the shape of a perforated plate in which each hole is formed into a long tubular shape in a porous cross section, and is provided so that the communication direction of each hole is along the slope direction of the ridge, and is in the middle of the slope direction of the ridge. In addition to forming a space divided by, the structure is such that the end face on the outside of the ridge is cut so that it is horizontal. In Patent Document 1, this porous body prevents the intrusion of powdered snow and the like. It is described that since the end face of the outside of the ridge of the porous body is horizontal, it is possible to maintain sufficient ventilation performance without the powder snow remaining and falling by its own weight and the air permeability being impaired.

In addition, in Patent Document 2, by arranging a plug structure made of a non-woven fabric so as to cover the opening in the vicinity of the inside of the opening of the ventilation layer serving as a ventilation path, the open portion of the ventilation layer is formed. It is described to prevent rain and snow from blowing in. In the stopper structure, a sheet-shaped non-woven fabric is shredded into narrow pieces, then these are curved in a wavy shape, and the convex portions of the curved narrow-width ribbons are arranged so as to be in contact with each other. It is formed in a honeycomb shape by sequentially adhering it, and each non-woven fabric covers the entire opening of the ventilation layer so that the outside air passes through the inside of the fiber structure of the non-woven fabric instead of many through holes in the honeycomb. It is stated that the plug structure is installed in the ventilation layer. In addition, by adjusting the adhesive strength between each non-woven fabric of the plug structure so that it can be peeled off one by one from the outside after installation, if dust or dirt adheres and causes clogging, the ventilation capacity is reduced. However, it is stated that it can be dealt with by removing only the outermost non-woven fabric.

Further, Patent Document 3 includes a main body having a vent on the upper portion and fixed to the ridge, a cover mounted on the main body, and a ventilation member arranged in a gap between the main body and the cover. The ridge ventilation system is listed. The ventilation member is for ensuring sufficient ventilation and preventing the passage of rain and snow as much as possible, and is provided with a large number of narrow ventilation passages that penetrate vertically and horizontally at the time of installation. , It is described that a plurality of plastic plates in which a large number of air passages are arranged side by side are laminated and fixed.

As described above, by providing the porous body of Patent Document 1, the plug structure made of the non-woven fabric of Patent Document 2, or the ventilation member of Patent Document 3 on the ventilation path of the ventilation ridge, the ventilation ridge can be used even in a snowy area. It is thought that the invasion of snow can be prevented. However, in the case of Patent Document 1, it seems that the pores of the porous body need to be arranged in parallel, and the diameters of the pores need to be uniformly uniform. It costs money to keep. In addition, since each hole of the porous body must be kept in the correct orientation on the ventilation path of the ventilation ridge, it is necessary to pay attention to the orientation and position of the porous body when constructing the porous body. Because there is, it takes time and effort for construction. And since the end face of the outside of the ridge of the porous body needs to be cut so as to be horizontal, if the slope of the sloped roof is different, the angle of the end face that needs to be cut of the porous body is also different. If the end face of the porous body is cut according to the slope of the sloped roof, it will take time and effort for construction, and if multiple porous bodies whose end faces are cut in advance according to the slope of the sloped roof are prepared, it will be used for inventory management. It is costly and there is a risk of ordering mistakes.

Further, in the case of Patent Document 2, it is a honeycomb-shaped stopper structure in which a nonwoven fabric of a plurality of corrugated narrow ribbons is adhered, and the stopper structure is formed so that outside air passes through the inside of the fiber structure of the nonwoven fabric instead of the honeycomb. Since it is necessary to arrange the plug structure and fix it in the correct position in the correct direction during construction, it takes time and effort for construction. Further, the non-woven fabric has a problem that clogging is likely to occur due to dust and dirt. Regarding this, Patent Document 2 states that it can be dealt with by adjusting the adhesive strength of each non-woven fabric of the plug structure so that the non-woven fabrics can be peeled off one by one and removing only the outermost non-woven fabric causing the first clogging. When the plug structure of Patent Document 2 is installed in the ventilation ridge, the ventilation ridge is provided in the building which is the top of the sloped roof. It is usually difficult to go to remove the non-woven fabric, and it is also difficult to check if it is clogged.

Further, in the case of Patent Document 3, as the ventilation member, a plurality of plastic plates in which a large number of ventilation passages are arranged side by side are laminated and fixed, and the ventilation passage of the ventilation member is vertically oriented on the ventilation passage of the ventilation ridge. Since it is installed in a direction that penetrates through the floor, it is necessary to fix and install the ventilation member in the correct direction and position during construction, which takes time and effort.

As described above, in the snow-proof ventilation ridge structure for preventing snow from blowing in the conventional ventilation ridge, a specific direction such as the porous body of Patent Document 1, the plug structure of Patent Document 2, or the ventilation member of Patent Document 3 Snow-proofing members formed to prevent snow from blowing in are placed in specific directions and positions on the ventilation path of the ventilation ridge, making the ventilation ridge special for installing snow-proofing members. It was necessary to have a structure, and the snow-proof member itself had a complicated structure. In addition, when constructing the snowproof member, it is necessary to fix and install the snowproof member by using some fixing means such as screws and bolts while confirming that the snowproof member is in the correct orientation, which is complicated. ..

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a snow-proof ventilation ridge structure having a simple structure and easy construction.

In order to solve the above problems, in the snow-proof ventilation ridge structure according to the present invention, the upper part of the ridge ventilation port formed in the ridge with a sloped roof is covered with a ridge wrapping member, and the ridge wrapping member and the ridge with the sloped roof A ventilation ridge in which ventilation gaps are formed between the roof surfaces on both sides, and each roof surface of the inner space of the ridge wrapping member along each of the ventilation gaps in order to prevent snow from blowing in from each of the ventilation gaps. Each of the snowproof members is provided with a snowproof member placed on the roof, and each of the snowproof members has a substantially cylindrical outer shape, has rigidity that the outer shape does not deform in the radial direction due to its own weight, and the ventilation corresponding to the diameter. It is characterized in that it is formed larger than the width of the gap.

Preferably, in the snow-proof ventilation ridge structure according to the present invention, the snow-proof member is a cylinder composed of a core portion arranged in the center and a large number of hair materials extending linearly from the core portion around the core portion. It is characterized by being formed in the shape of a brush.

The construction method of the snow-proof and ventilation ridge structure according to the present invention is the above-mentioned construction method of the snow-proof and ventilation ridge structure, and the ridge-wrapping member is placed on the roof surfaces on both sides of the ridge before the ridge-wrapping member is attached to the ridge. It is provided with a snow-proof member mounting step for mounting the snow-proof member and a ridge-wrapping member mounting step for covering the ridge-wrapping member so as to cover the ridge ventilation port and each of the ridge-proof members and attaching the ridge-wrapping member to the ridge. It is a feature.

Preferably, the construction method of the snow-proof ventilation ridge structure according to the present invention is a ridge-wrapping member mounting tool installation step in which a plurality of ridge-wrapping member mounting tools are installed in the building at intervals before the snow-proofing member mounting step. The ridge wrapping member is further provided with locking claws that project inward at each edge portion forming the ventilation gap, and each ridge wrapping member attachment is stretched on both sides of the ridge. A locking portion in which the overhanging portion, a hanging portion extending downward from both ends of the overhanging portion, and the locking claws of the ridge wrapping member formed on the outside of each of the hanging portions are locked. In the snow-proof member mounting step, the snow-proof member is mounted on the roof surface so as to be hooked on the inside of the hanging portion of the ridge-wrapping member mounting tool, and the ridge-wrapping member mounting step. In the above, the ridge wrapping member is pushed into the plurality of ridge wrapping member attachments from above, and the locking claws provided on each of the edge portions of the ridge wrapping member are each of the plurality of ridge wrapping members. It is characterized in that the ridge wrapping member is attached to the ridge by locking the fitting to each of the locking portions.

In the snow-proof ventilation ridge structure according to the present invention, in order to prevent snow from blowing in from the ventilation gap formed between the ridge-wrapping member of the ventilation ridge and the roof surface, the snow-proof member is the roof surface of the inner space of the ridge-wrapping member. It is provided so that it can be placed on top. The snow-proof member placed on the roof surface has a substantially cylindrical outer shape and has rigidity that the outer shape does not deform in the radial direction due to its own weight, so that it will naturally roll down due to gravity along the slope of the roof surface. However, since the diameter of the snow-proof member is formed to be larger than the width of the ventilation gap, the snow-proof member is located in the inner space of the ridge-wrapping member so as to be caught by the ridge-wrapping member and close the ventilation gap. Therefore, the snow-proof member prevents snow from being blown through the ventilation gap. Further, even when the snow-proof member is moved by a strong wind or the like, the snow-proof member naturally rolls down along the roof surface due to gravity and returns to the original position of closing the ventilation gap, and exhibits snow-proof performance. As described above, the snow-proof member of the snow-proof ventilation ridge structure according to the present invention does not need to be fixed to the roof surface, the ridge wrapping member, or the like, and is simply placed on the roof surface of the inner space of the ridge wrapping member. Therefore, construction is easy. In addition, the ventilation ridge does not need to be specially configured for snowfall areas, and the upper part of the ridge ventilation port formed in the ridge with a sloping roof is covered with a ridge wrapping member on both sides of the ridge wrapping member and the ridge with a sloping roof. If the ventilation building has a ventilation gap formed between it and the roof surface and a space is provided in the inner space of the ridge wrapping member so that the snow-proof member can be installed, the snow-proof member is installed in the space. Since the snow-proof ventilation ridge structure according to the present invention can be used, the ventilation ridge of the snow-proof ventilation ridge structure according to the present invention uses the ventilation ridge for general land and members that do not require the snow-proof function in common. It can be configured and the cost can be reduced. Further, even if the existing ventilation ridge has the same configuration as the ventilation ridge of the snow-proof ventilation ridge structure according to the present invention, the snow-proof specification can be easily obtained by simply installing the snow-proof member according to the present invention. Can be done.

Preferably, in the snow-proof ventilation building structure according to the present invention, the snow-proof member is a cylinder composed of a core portion arranged in the center and a large number of hair materials extending linearly from the core portion around the core portion. Since it is formed in a brush shape, a large number of fine gaps are formed between a large number of hair materials, and even if a snow-proof member is provided so as to close the ventilation gap, the space between the hair materials is provided. It is possible to ventilate through the gaps formed in the area, and the snow that is about to be blown from the outdoor side cannot pass through the gaps formed between the hair materials because it is a collection of ice crystals that have grown to a certain size. The entry is prevented. At this time, since the hair material extends in a radial linear shape from the core portion, the gap formed between a large number of hair materials becomes narrower as it gets closer to the core portion, and the snow-proof member moves away from the core portion. The closer to the outer peripheral surface, the wider the interval tends to be. The snow caught in the gaps between many hair materials melts into water, or when the snow gathers and becomes a certain weight, it tries to flow down due to gravity, but below the core, the hair material Since the gap between them will try to flow from the narrow side to the wide side, water and snow will not be held in the gap between the hair materials for a long time and will easily flow out to the outside of the snowproof member, and the snowproof performance will be ensured while ensuring ventilation performance. Can be demonstrated.

The construction method of the snow-proof and ventilation ridge structure according to the present invention is the above-mentioned construction method of the snow-proof and ventilation ridge structure, respectively, on the roof surfaces on both sides of the ridge before the ridge wrapping member is attached to the ridge. It is provided with a snow-proof member mounting step for mounting the snow-proof member and a ridge-wrapping member mounting step for covering the ridge-wrapping member so as to cover the ridge ventilation port and each of the ridge-proof members and attaching the ridge-wrapping member to the ridge. As a feature, the snowproof member can be installed simply by placing the snowproof member on the roof surface and attaching it to the ridge so as to cover the ridge wrapping member from above, so that the construction is easy.

Preferably, the construction method of the snow-proof ventilation ridge structure according to the present invention is a ridge-wrapping member mounting tool installation step in which a plurality of ridge-wrapping member mounting tools are installed in the building at intervals before the snow-proofing member mounting step. The ridge wrapping member is further provided with locking claws that project inward at the edges forming the ventilation gaps, and the ridge wrapping member attachments are stretched on both sides of the ridge. A locking portion in which the overhanging portion, a hanging portion extending downward from both ends of the overhanging portion, and the locking claws of the ridge wrapping member formed on the outside of each of the hanging portions are locked. In the snow-proof member mounting step, the snow-proof member is mounted on the roof surface so as to be hooked on the inside of the hanging portion of the ridge-wrapping member mounting tool, and the ridge-wrapping member mounting step. In the above, the ridge wrapping member is pushed into the plurality of ridge wrapping member attachments from above, and the locking claws provided on each of the edge portions of the ridge wrapping member are each of the plurality of ridge wrapping members. The ridge wrapping member is attached to the ridge by locking it to each of the locking portions of the ridge, and each of the ridge wrapping member fittings is locked with the locking claws of the ridge wrapping member. It has a locking part, and multiple ridge wrapping members are installed at intervals in the ridge to attach the ridge wrapping member. Since the ridge wrapping member can be attached to the ridge by pushing the wrapping member from above and locking the locking claws of the ridge wrapping member to the locking portion of each ridge wrapping member mounting tool, the ridge wrapping member can be installed. It's easy. Further, before the ridge wrapping member is attached to the ridge in the ridge wrapping member mounting process, the snow proof member is installed in the snow proof member mounting process. At this time, a plurality of ridge wrapping member attachments are installed in the ridge. .. In the process of mounting the snow-proof member, the slope of the sloped roof is large by hooking the snow-proof member on the inside of the hanging portion of the ridge wrapping member mounting tool so that the snow-proof member is placed on the roof surface. Even in this case, the snow-proof member is prevented from rolling down by the hanging of the ridge-wrapping member attachment for attaching the ridge-wrapping member without taking special measures to prevent the snow-proof member from rolling down along the roof surface. Then, in the subsequent step of attaching the ridge wrapping member, the ridge wrapping member can be easily installed.

In the present embodiment, a case where the pair of roof surfaces 22 of the sloped roof 2 is remodeled by the layered roofing method is shown as an example. As shown in FIG. 2, a plurality of rafters 32 are erected on the main building 31, the main building (not shown) and the eaves girder (not shown) at an angle diagonally downward from the building 21 side toward the eaves side. The lower ground of the roof surface 22 is formed by laying the field board 33 on these rafters 32. Then, after the existing roofing for waterproofing is laid on the field board 33, the existing roofing material 35 is covered to form the existing roof surface 22 which was the roof surface 22 before the remodeling. The existing roofing 34 is a sheet-shaped waterproofing material, and asphalt roofing in which asphalt is impregnated into a base material such as paperboard or felt, which is generally widely used as a waterproofing material for roofs, is used. The existing roofing material 35 is a flat roofing material, and a flat plate-shaped decorative slate material containing cement as a main component, which is generally widely used as a roofing material, is used. If the existing roofing 34 or the existing roofing material 35 is damaged due to aged deterioration or the like, it may cause problems such as rain leaks, and therefore reform is performed.

In the present embodiment, a flat slate roofing material is used as the existing roofing material 35, and the existing roof surface formed by roofing the existing roofing material 35 is substantially flat, and the existing roofing 34 and the existing roofing material 35 are installed. Without removing the roofing material 35, a new roofing 36 is laid on the existing roofing surface formed by the existing roofing material 35 as it is, and the new roofing material 37 is laid on the new roofing material 37 to make the new roofing surface. It is remodeled from the existing roof surface to the new roof surface by the layered roofing method to be formed. The new roof surface formed by roofing the new roof material 37 is the roof surface 22. The new roofing 36 is a sheet-shaped waterproof material, and asphalt roofing is used as in the existing roofing 34. The new roofing material 37 is a metal roofing material formed of a lightweight thin plate-shaped metal plate because it is roofed on the existing roofing material 35 without removing it, and the galvanized steel plate is used as a base material. A metal roofing material based on a hot-dip 55% aluminum-galvanized steel sheet, which has higher corrosion resistance than the tin roofing material, is used. In the present embodiment, the newly installed roofing material 37 is formed horizontally and has engaging portions at the upper end and the lower end, and the building 21 is provided one step at a time from the eaves side of the roof surface 22 toward the building 21. The new roofing material 37, which is roofed along the extending direction and is adjacent to each other in the upper and lower stages, engages the engaging portion of the upper end portion of the new roofing material 37 in the lower stage with the engaging portion of the lower end portion of the new roofing material 37 in the upper stage. It is connected by matching. Further, in the present embodiment, the new roofing material 37 is provided with a rising portion on the lower end side, and the new roof surface is a stepped roof that inclines substantially in a step shape from the ridge 21 side toward the eaves side. It is a face. The heat insulating material 38 is formed in the space having a substantially triangular cross section formed between the new roofing material 37 and the new roofing 36 laid on the existing roof surface by the rising portion provided on the lower end side of the new roofing material 37. Is filled to enhance the heat insulating property of the sloped roof 2. The heat insulating material 38 is a general roof heat insulating material, and polystyrene foam is used.

The ventilation ridge 4 has a structure for ventilation of the cabin back 23 provided in the ridge 21 of the sloped roof 2 as described above. The ventilation ridge 4 includes a ridge ventilation port 41 formed in the ridge 21 of the sloped roof 2 and a ridge wrapping member 42 that covers the upper part of the ridge ventilation port 41. The ridge ventilation port 41 is a slit-shaped opening that penetrates the sloped roof 2 to the cabin back 23 along the ridge 21, and ventilation is possible between the cabin back 23 and the outdoor side via the ridge ventilation port 41. There is. The ridge ventilation port 41 may be provided over the entire length of the ridge 21, or may be provided in a part of the ridge 21.

The ridge wrapping member 42 is attached to the ridge 21 so as to cover the upper part of the ridge ventilation port 41. Since the ridge ventilation port 41 is an opening that penetrates the ridge 21 of the sloped roof 2 in the vertical direction, it will rain from the ridge ventilation port 41 to the back of the cabin 23 when it rains. Therefore, by covering the upper part of the ridge ventilation port 41 with the ridge wrapping member 42, it is possible to prevent rain from directly falling on the back of the cabin 23. The ridge wrapping member 42 may be formed to have a length that covers the ridge ventilation port 41, and when the ridge ventilation port 41 is formed over the entire length of the ridge 21, the ridge wrapping member 42 also covers the entire length of the ridge 21. When the ridge ventilation port 41 is provided and is formed only in a part of the ridge 21, the ridge wrapping member 42 may be provided in only a part of the ridge 21 so as to cover the ridge ventilation port 41.

Since the ventilation ridge 4 is a structure for ventilation of the back of the hut 23, the ridge wrapping member 42 is attached to the ridge 21 so as to cover the upper part of the ridge ventilation port 41, and at that time, the ridge wrapping member 42 and the ridge wrapping member 42 are attached. A ventilation gap 43 is formed between the pair of roof surfaces 22 on both sides of the ridge 21.

In the present embodiment, the roof surface 22 of the sloped roof 2 is remodeled by superimposing a new roof surface on the existing roof surface, and the ventilation ridge 4 is also provided at the time of the remodeling. Here, as shown in FIG. 2, a pair of field boards 33 forming the lower ground of the pair of roofing surfaces 22 are arranged so as to form a slit-shaped gap between the top portions of each. The existing roofing 34 and the existing roofing material 35 are laid on the field board 33 so as not to close the gap, and an opening penetrating to the back of the hut 23 is formed in the ridge 21 on the existing roof surface. .. A base material 45 is provided at the top of each of the pair of existing roof surfaces along the opening formed in the ridge 21 of the existing roof surface. The base material 45 is a square lumber having a rectangular cross section, and mounting brackets and the like are placed on the existing roof surface formed by the existing roof material 35 whose bottom surface of the base material 45 has an inclined surface substantially equal to the slope of the field board 33. The upper surface facing the bottom surface of each base material 45 is located above the existing roof surface and is inclined diagonally downward with a slope substantially equal to the slope of the field board 33 toward the eaves side. It has become. The side surfaces and the upper surface of each base material 45 on the eaves side are covered with a new roofing 36 laid on each existing roof surface to provide waterproof measures. The new roofing material 37 forming the new roof surface is covered from the eaves side to the ridge 21 side to the front of the base material 45. Since the new roofing material 37 is provided with a rising portion on the lower end side, the new roofing surface formed by the new roofing material 37 is a substantially stepped roof surface, as shown in FIG. Assuming that the surface parallel to the field plate 33 passing through the top of the rising portion of each new roofing material 37 of this new roofing surface is the reference roofing surface 221 and the surface parallel to the field plate 33 is set, the upper surface of the base material 45 is above the reference roofing surface 221. It is designed to protrude.

Then, a covering portion covering from the upper end of the upper surface of the base material 45 and the side surface on the eaves side to a substantially position where the side surface and the reference roof surface 221 intersect, and the reference roof surface 221 from the lower end side of the covering portion toward the eaves side. A draining plate 46 having an extending portion extending diagonally downward along the surface is attached to each base material 45. In the present embodiment, the draining plate 46 is formed by using a metal plate material based on a molten 55% aluminum-zinc alloy plated steel plate, similarly to the new roofing material 37. The upper surface of the extension portion of the drainer plate 46 is arranged on substantially the same plane as the reference roof surface 221. It is located above the new roofing material 37, and the upper part of the engaging portion at the upper end of the new roofing material 37 is covered with the extending portion of the draining plate 46. A watertight material 47 is provided between the extending portion of the draining plate 46 and the new roofing material 37 thatched on the most side of the ridge 21 to prevent rainwater and the like from entering. As the watertight material 47, a general waterproof packing material made of foam rubber or the like can be used. As described above, in the present embodiment, the extending portion of the draining plate 46 is provided on substantially the same plane as the reference roof surface 221 of the new roof surface formed by the new roofing material 37, and the extending portion of the draining plate 46 is provided. The protruding part is also regarded as the roof surface 22.

The covering portion of the draining plate 46 covers the entire upper surface of the base material 45, and the end portion of the covering portion of the draining plate 46 on the ridge 21 side is from the end side of the upper surface of the base material 45 on the ridge 21 side. May be provided so as to project toward the ridge 21 side, but the protruding length is the end of the covering portion of the draining plate 46 provided on the base material 45 on both sides of the ridge 21 on the ridge 21 side. The length is such that a gap of a predetermined interval is provided between the portions. The gap formed between the ends of the covering portions of the draining plates 46 on both sides of the ridge 21 on the ridge 21 side is an opening constituting the ridge ventilation port 41, and the opening is the reference roof surface 221. It is provided at a position raised upward by the base material 45. As described above, in the present embodiment, the ridge 21 of the sloped roof 2 is raised above the reference roof surface 221 by the base material 45, and the ridge ventilation port 41 is raised in the raised ridge 21 and the back of the cabin 23. It is formed so as to penetrate in the vertical direction.

At the end of the covering portion of the draining plate 46 on the ridge 21 side, a return piece portion is provided as if the edge portion of the covering portion on the ridge 21 side was bent upward and the tip thereof was formed toward the eaves side. May be. Further, a protruding angle portion protruding toward the eaves may be provided at a folded portion from the surface of the covering portion of the draining plate 46 that covers the upper surface of the base material 45 to the surface that covers the side surface of the base material 45 on the eaves side. The protruding corner portion is bent toward the side surface of the base material 45 on the eaves side after projecting the surface covering the upper surface of the base material 45 of the covering portion toward the eaves side from the surface covering the side surface of the base material 45 on the eaves side. It is formed in this way. Since the ridge ventilation port 41 is provided at a position raised above the roof surface 22 by the base material 45, even if rainwater comes up the roof surface 22 during a strong wind or the like, the ridge ventilation port 41 is provided from the roof surface 22. The side surface of the base material 45 on the eaves side and the drain plate 46 covering it prevent rainwater from reaching the ridge ventilation port 41. Further, even if rainwater adheres to the surface covering the upper surface of the base material 45 of the covering portion of the draining plate 46 due to water splashing or the like, the surface is inclined downward toward the eaves side like the upper surface of the base material 45. Therefore, rainwater flows down to the eaves side. The protruding corner portion provided on the draining plate 46 reduces rainwater from adhering to the surface covering the upper surface of the base material 45 of the covering portion of the draining plate 46, and the return piece portion allows rainwater to adhere to the covering portion of the draining plate 46. When it adheres to the surface covering the upper surface of the base material 45, it surely prevents rainwater from entering the building ventilation port 41.

In the present embodiment, the ridge wrapping member 42 extends downward from the upper plate portion 421 formed in a substantially mountain-shaped cross section and the opposite end sides of the upper plate portion 421 across the top of the substantially mountain-shaped cross section. It is provided with a hanging plate portion 422. The ridge wrapping member 42 is arranged above the ridge ventilation port 41 so that the top of the upper plate portion 421 having a substantially mountain-shaped cross section is parallel to the direction in which the ridge 21 extends, and diagonally downward from the top to both sides. A pair of inclined surfaces having a substantially mountain-shaped cross section of the upper plate portion 421 extending to the ridge 21 are attached to the ridge 21 so as to be substantially parallel to the reference roof surface 221 of the pair of roof surfaces 22 respectively. The ridge 21 is raised above the reference roof surface 221 by the base material 45, and the eaves side end edges of each pair of inclined surfaces of the upper plate portion 421 are drain plates 46 covering the upper surface of the base material 45. The hanging plate portion 422 projects downward from each eaves side end side of the pair of inclined surfaces of the upper plate portion 421 so as to protrude toward the eaves side from the eaves side end portion of the surface of the covering portion. The height position of the lower end side of the portion 422 is positioned above the roof surface 22 immediately below the lower end side by a predetermined distance L1. The slit-shaped gap formed between the lower end side of each of the hanging plate portions 422 and the roof surface 22 below the lower end plate portion 422 extending in the direction of the ridge 21 at a distance L1 is a ventilation gap 43, respectively. The area surrounded by the upper plate portion 421 of the ridge wrapping member 42, the hanging plate portions 422 on both sides thereof, and the pair of roof surfaces 22 of the sloped roof 2 is the inner space of the ridge wrapping member 42, and the back of the hut 23. When the air and moisture of the roof are discharged to the outside, they enter the inner space of the ridge wrapping member 42 from the back of the roof 23 through the ridge ventilation port 41, and both sides sandwiching the ridge 21 in the inner space of the ridge wrapping member 42. It flows along any one of the roof surfaces 22 and is discharged to the outside through the ventilation gap 43. As described above, in the ventilation ridge 4, the ridge ventilation port 41, the inner space of the ridge wrapping member 42, and the ventilation gaps 43 on both sides thereof serve as a ventilation route from the back of the cabin 23 to the outside. In the present embodiment, the eaves side end edges of the pair of inclined surfaces of the upper plate portion 421 are the extending portions of the draining plate 46 extending from the eaves side side surface of the base material 45 to the eaves side along the reference roof surface 221. Positioned above, each hanging plate portion 422 extends substantially vertically downward, and each ventilation gap 43 is formed between the lower end side of each hanging plate portion 422 and the extending portion of the draining plate 46 below the lower end side. It has become like. Since each eaves side end side portion of the upper plate portion 421 protrudes toward the eaves side from the portion raised by the base material 45 of the ridge 21, each hanging plate portion 422 has each base material. It is arranged at a distance from the eaves side side surface of the 45, and the inner space of the ridge wrapping member 42 is the surface of the covering portion of the draining plate 46 covering the eaves side side surface of the hanging plate portion 422 and the base material 45, respectively, on both sides. , A space surrounded by the upper plate portion 421 and the extending portion of the draining plate 46 which is the roof surface 22 in the present embodiment is provided, and the snowproof member 5 is arranged in each of the spaces. It has become.

Each of the snowproof members 5 is provided in the inner space of the ridge wrapping member 42 in order to prevent snow from blowing into the cabin back 23 through the ventilation gaps 43 formed between the ridge wrapping member 42 and the pair of roof surfaces 22. Each is provided along the ventilation gap 43. Each snowproof member 5 has a substantially cylindrical outer shape, has a rigidity that the outer shape does not deform in the radial direction due to its own weight, and is formed to have a diameter larger than the width of the corresponding ventilation gap 43. In the snow-proof ventilation ridge structure 1, the snow-proof member 5 is placed on the roof surface 22 in the inner space of the ridge-wrapping member 42 without being fixed to the roof surface 22, the ridge-wrapping member 42, or the like. ing. Since the snowproof member 5 has a substantially cylindrical outer shape and has rigidity that the outer shape does not change in the radial direction due to its own weight, the snowproof member 5 is placed on the roof surface 22 so that its central axis extends in the direction of the ridge 21. , Trying to roll down to the eaves side according to the slope of the roof surface 22. However, the hanging plate portion 422 exists on the eaves side of the inner space of the ridge wrapping member 42, and a ventilation gap 43 is formed between the lower end side of the hanging plate portion 422 and the roof surface 22, and the snowproof member 5 Since the outer diameter of the outer shape is formed to be larger than the width of the ventilation gap 43, the snow-proof member 5 that is about to roll down is caught in the hanging plate portion 422 and locked. Therefore, in the snow-proof ventilation ridge structure 1 according to the present embodiment, it is not necessary to perform precise positioning work or fixing work of the snow-proof member 5, and when the ridge-wrapping member 42 is attached to the ridge 21, the snow-proof member 5 is attached to the roof surface. By simply placing it on the ridge 22 and covering it with the ridge wrapping member 42, the snowproof member 5 is naturally arranged at a position in the inner space of the ridge wrapping member 42 so as to close the ventilation gap 43. The snow-proof member 5 prevents snow from being blown from the ventilation gap 43.

The snow-proof member 5 needs to have a structure that ensures ventilation performance from the ventilation gap 43 while preventing snow from blowing in from the ventilation gap 43. As shown in FIG. 4, the snow-proof member 5 of the present embodiment is a cylinder composed of a core portion 51 arranged in the center and a large number of hair members 52 extending linearly from the core portion 51 around the core portion 51. It is formed like a brush. A large number of fine gaps will be formed between the large number of hair materials 52, and even if the snow-proof member 5 is provided so as to close the ventilation gap 43 by appropriately adjusting the density of the hair materials 52. The snow that is about to be blown from the ventilation gap 43 is a collection of ice crystals that have grown to a certain size, while ensuring ventilation performance by ventilation through the gaps formed between the hair materials 52. It is possible to prevent entry without passing through the gap formed between the materials 52. At this time, since the hair material 52 extends in a radial linear shape from the core portion 51, the gap formed between the large number of hair materials 52 becomes narrower as it gets closer to the core portion 51, and the core portion 51 The closer to the outer peripheral surface of the snow-proof member 5 having a cylindrical outer shape, the wider the distance tends to be. The snow caught in the gaps between a large number of hair materials 52 melts and becomes water, or when the caught snow gathers and becomes a certain weight, it tends to flow down due to gravity, but below the core 51 Since the gap between the hair materials 52 tends to flow from the narrow side to the wide side, it is easy to flow out, and water and snow are not held in the gap between the hair materials 52 for a long time while ensuring ventilation performance. It can demonstrate snowproof performance. The size of the diameter of the snow-proof member 5 should be larger than the distance L1 which is the width of the ventilation gap 43 so that the snow-proof member 5 is locked to the hanging plate portion 422 without coming out from the ventilation gap 43. However, if the diameter of the snow-proof member 5 is formed to be about twice the diameter of the distance L1, the possibility that the snow-proof member 5 will escape from the ventilation gap 43 to the outside can be further reduced, and snow and water can be removed. It is more preferable because the ventilation gap 43 is closed by the hair material 52 in the lower half from the core portion 51 which easily flows out. As such a snowproof member 5, a general twisting brush manufactured by using two or four wires on the core portion 51 and twisting the hair member 52 between them can be used. The material of the hair material 52 is not particularly limited to resin, metal, natural animal or plant fibers, etc., and after being formed as the snow-proof member 5, the outer shape of the snow-proof member 5 as a whole is its own weight in the radial direction. As long as it has a rigidity that does not change depending on the type of scrubbing brush, a hair material used for a general scrubbing brush may be used. Therefore, the snowproof member 5 can be manufactured at low cost.

In the present embodiment, the ridge wrapping member attachment 6 is used to attach the ridge wrapping member 42. As shown in FIG. 5, a plurality of ridge wrapping member attachments 6 are installed in the ridge 21 at intervals from each other, and the ridge wrapping member 42 is attached to the ridge wrapping member attachments 6 to attach the ridge wrapping member 42 to the ridge. The wrapping member 42 can be attached to the ridge 21. In the present embodiment, the ridge ventilation port 41 is provided in a portion raised above the reference roof surface 221 by the base material 45 of the ridge 21, and the ridge wrapping member attachment 6 is the ridge 21 of the ridge 21. It can be attached to the raised part. The ridge wrapping member attachment 6 has an overhanging portion 61 overhanging on both sides of the ridge 21, a hanging portion 62 extending downward from both ends of the overhanging portion 61, and a locking formed on the outside of each hanging portion 62. A unit 63 is provided. The overhanging portion 61 covers the surface of the covering portion of the draining plate 46 that covers the upper surface of the ridge ventilation port 41 and the base material 45 on both sides thereof, and projects toward the eaves side from the eaves side end side of each surface. There is a gap between the hanging portion 62 extending downward from both ends of the overhanging portion 61 and the surface of the covering portion of the draining plate 46 covering the eaves side side surface of each base material 45. It is supposed to be. The distance between the outsides of the hanging portions 62 on both sides of the overhanging portion 61 is formed to be substantially equal to the distance between the insides of the hanging plate portions 422 on both sides of the ridge wrapping member 42, and the hanging portion 62 and the base material 45 are formed. The snowproof member 5 can be arranged in a space surrounded by the side surface on the eaves side, the overhanging portion 61, and the roof surface 22. Locking claws 423 projecting inward are formed at the edge portions of the ridge wrapping members 42 forming the ventilation gaps 43, that is, the lower ends of the hanging plate portions 422, and the ridge wrapping members 42 are ridges. The locking claws 423 provided on each hanging plate portion 422 are pushed into the plurality of ridge wrapping member attachments 6 installed in 21 from above, and the hanging claws 423 on both sides of each ridge wrapping member attachment 6 are lowered. It can be attached to the ridge 21 by locking it to the locking portion 63 provided in the 62. A spacer (not shown) such as a waterproof material is provided on the upper surface of the overhanging portion 61 of each ridge wrapping member attachment 6 so that each spacer is in contact with the lower surface of the upper plate portion 421 of the ridge wrapping member 42. May be good. As a result, the load applied to the ridge wrapping member 42 can be dispersed to reduce the risk of the upper plate portion 421 being deformed or the locking claw 423 and the locking portion 63 being damaged, and the ridge wrapping member can be reduced by at least the thickness of the spacer. The lower surface of the upper surface portion 421 of the 42 is arranged at a position higher than the ridge ventilation port 41, and the ridge wrapping member fittings 6 on which the spacers are arranged are provided at intervals from each other, so that the ventilation path can be provided. It will be secured.

As described above, according to the snow-proof ventilation ridge structure 1 according to the present embodiment, the snow-proof member 5 can be manufactured at low cost with a simple configuration, and the snow-proof member 5 is also installed on the roof surface 22 respectively. Then, it can be easily constructed by simply covering the ridge wrapping member 42 from above. The snow-proof member 5 is constructed in the shape of a cylindrical brush composed of a core portion 51 arranged in the center and a large number of hair members 52 extending linearly from the core portion 51 around the core portion 51. Sometimes it is not necessary to worry about the orientation of the snowproof member 5, and compared to the case of a snowproof member in which ventilation holes are formed so as to be oriented in a specific direction, construction can be performed more easily and construction mistakes can be reduced. .. Since the snow-proof member 5 has a core portion 51 at the center of a substantially cylindrical outer shape, it is difficult to bend, and during construction, the snow-proof member 5 is placed on the roof surface 22 and covered with the ridge wrapping member 42. The snow-proof member 5 is easy to install because it does not bend significantly just by lightly pressing it so that the snow-proof member 5 does not fall. At this time, as a means for holding the snow-proof member 5 so that it does not fall, it is sufficient to hold it by hand without using any special tool or means. Further, when the ridge wrapping member attachment 6 is used for attaching the ridge wrapping member 42 as in the present embodiment, the hanging portion 62 of the ridge wrapping member attachment 6 is used at the time of construction. If the snow-proof member 5 is hooked on the hanging portion 62, it is not necessary to hold the snow-proof member 5 by hand, so that the construction is easier.

In the present embodiment, the ventilation gap 43 is formed between the ridge wrapping member 42 and the extending portion of the draining plate 46, but extends to the eaves side of the extending portion of the draining plate 46, for example. When the length to be taken out is short, or when the draining plate 46 is not provided, the eaves side end side of the upper plate portion 421 of the ridge wrapping member 42 extends above the newly installed roofing material 37. A ventilation gap 43 may be formed between the newly installed roofing material 37 and the lower end side of the hanging plate portion 422 of the ridge wrapping member 42. However, when a rising portion is provided on the lower end side or an engaging portion is provided on the upper end as in the new roofing material 37 of the present embodiment, they install the snowproof member 5. In such a case, the drainer plate 46 may be used as in the present embodiment because the slope of the surface of the new roofing material 37 on which the snowproof member 5 is placed may be too small. It is preferable to provide a ventilation gap 43 between the draining plate 46 and the roof wrapping member 42. Further, in the present embodiment, the extending portion of the draining plate 46 is arranged on substantially the same plane as the reference roof surface 221 but is not arranged on substantially the same plane as the reference roof surface 221. A ventilation gap 43 may be formed between the extending portion of the draining plate 46 and the ridge wrapping member 42. In this case, the extending portion of the draining plate 46 may be a surface that inclines diagonally downward toward the eaves side with a constant gradient.

The roof surface 22 of the sloped roof 2 of the present embodiment was remodeled by overlaying a new roofing material 37 on the existing roof surface, and the snow-proof ventilation ridge structure 1 was provided at the time of the remodeling. However, a snow-proof ventilation ridge structure 1 may be provided at the time of new construction. Further, if the same ventilation ridge 4 as in the present embodiment is already provided on the sloped roof 2 at the time of new construction or the like, the existing ventilation ridge 4 is used as it is without the overall remodeling of the roof. 5 can be easily constructed to form a snow-proof ventilation ridge structure 1 having a snow-proof function later. Further, the sloped roof 2 of the present embodiment is a gable roof that covers the entire upper part of the house, but in addition, only a part of the roof is used, for example, a hipped roof or an Irimaya building. Similarly, in a building having a roof such as a sloped roof 2, the snow-proof and ventilation building structure 1 can be applied to the portion of the sloped roof 2.

The snow-proof ventilation ridge structure according to the present invention is a structure for preventing snow from blowing in the ventilation ridge provided in the ridge portion of the sloped roof, but is also applicable to ventilation structures provided in other than the other ridge portions. there is a possibility.
