Description

  The present invention relates to an attic shield member used for roof construction of a wooden building.

  Wooden buildings are often constructed by a frame construction method, and the roof of a wooden building is almost constant on the purlin and eaves girder and on the purlin girder placed between them, so that they are perpendicular to the girder. In general, after rafters are arranged at intervals, a roofing material such as a roof tile is spread on a rafter with a base plate and a waterproof sheet.

  Rainwater infiltration or leakage can cause decay of wood, including girders, rafters, and field boards, shortening the useful life of buildings, increase indoor humidity, and cause damage to household items such as tatami mats and furniture. Become. Although attempts have been made to prevent rainwater infiltration and leakage by placing a waterproof sheet such as synthetic resin sheet, waterproof paper, asphalt roofing, etc. on top of the ground plate, it is due to wind and rain, radiant heat from the sun, and long-term use. A part of the waterproof sheet may be damaged or deformed due to deterioration or the like, and infiltration or leakage of rainwater may be permitted. In addition, the waterproof sheet is generally attached to the base plate with a fastening material such as a nail or a staple, but there is a possibility that rainwater may infiltrate or leak from a slight gap generated at the fastening material attachment site. In order to avoid the decay of wood and prevent the indoor humidity from increasing, it is not sufficient to use only the above-mentioned waterproof sheet. By further waterproofing, the wood such as girders, rafters and field boards are dried. It is necessary to keep it in the same state.

  On the other hand, the temperature of the roofing material is increased by direct sunlight, and may reach about 70 ° C. Along with this, the indoor temperature rises, which not only makes the resident uncomfortable, but also may damage the resident's health and damage the household property. In order to solve these problems, it is necessary to improve the heat insulation so that the indoor temperature does not rise even if the temperature of the roofing material rises. The strength of wooden buildings is borne by the wood, and it is not practical to use heavy heat insulating materials such as concrete heat insulating materials. Therefore, if there is a member that is lightweight and can form a heat insulation layer, it is effective for heat insulation construction of a wooden building.

  An attic shield member or a roof structure using a shield member used for the purpose of preventing infiltration or leakage of rainwater or for the purpose of forming a heat insulating layer to avoid an increase in indoor temperature is disclosed.

  For example, the building member described in Patent Document 1 is provided with a hook portion having an inverted U-shaped cross section for fitting on the upper surface of a rafter along both side edges, and is lower than the upper surface of the hook portion between both hook portions. It is a building member formed by forming a U-shaped cross-section groove that is recessed.

  In addition, the inventor of the present invention bent the left and right sides of the thin plate material upward so as to fit between the rafters and rafters arranged at equal intervals on the roof girder of the wooden building to form a concave groove and bend There is disclosed a shield member for a roof of a wooden building, characterized in that an end is horizontally bent outwardly to provide an engaging portion for engaging an upper surface of a rafter (see, for example, Patent Document 2). reference).

Furthermore, Patent Document 3 includes:
Rafters on the back of the field plate,
A ventilation spacer provided between the rafters adjacent to each other and formed by bending a flat plate;
The ventilation spacer includes a ventilation spacer body that secures a ventilation space between the base plate, a first fixing plate portion formed at one end of the ventilation spacer body, and the ventilation spacer. A second fixing plate formed on the other end,
The first fixed plate portion is fixed to one rafter or a field plate of adjacent rafters, and the second fixed plate portion is fixed to the other rafter or the field plate.
There is disclosed a roof structure characterized in that at least one refracting portion capable of adjusting a refraction angle is formed on the ventilation spacer body.

  However, since the building member described in Patent Document 1 needs to be attached so as to cover the rafters by a hook portion having an inverted U-shaped cross section, it cannot be installed in a state where the field board is attached. Therefore, although it can be used when building a roof of a new building, it is necessary to remove the field plate once when it is used to renovate an existing building, and cannot be easily applied.

  Further, the interval between adjacent rafters and the size of the rafters vary depending on the contractor, and it is necessary to create the building member according to the building each time construction is performed. Mass-produced building materials cannot be applied to all buildings, which requires processing costs and high costs.

  In order to prevent rainwater infiltration or leakage, or to form a heat insulation layer and avoid an indoor temperature rise, use the very long building member having the same length as the rafter, or use a plurality of building members. It is necessary to connect them along the rafter so that some of them overlap. When using building members that are the same length as the rafters, the length of the rafters differs depending on the individual building, so it is necessary to create the members each time construction is performed, and expensive processing costs are required, and very long building members should be used. Therefore, it takes a great deal of labor for transportation, installation, etc., making it difficult to perform construction work safely. On the other hand, when a part of the building member is overlapped, the overlapping part of the member becomes thick, resulting in unevenness, and when the field board is attached, a gap is formed, and rainwater infiltration or leakage occurs from the gap. There is a risk.

  Since the shield member described in Patent Document 2 is locked and fixed to the upper surface of the rafter, it cannot be attached in a state where the field board is already attached. Therefore, when it is used for renovation of an existing building, it is necessary to remove the field board once, and it cannot be easily applied.

  Since the locking part is a type that is hung on the top surface of the rafters, there is no need to worry about the difference between the rafter size contractors. It is necessary to create a shield member. The mass-produced shield member cannot be applied to all buildings, which may increase the processing cost.

  In order to prevent rainwater infiltration or leakage, or to form a heat insulating layer and avoid an indoor temperature rise, it is necessary to connect the shield members along a rafter so as to overlap each other. However, since the overlapped portion of the shield member is thick, unevenness is generated, and a gap is formed when the field plate is attached. Therefore, there is a possibility that rainwater infiltrates or leaks through the gap.

  The ventilation spacer according to the roof structure described in Patent Document 3 is an object that is attached to a roof and ceiling joint portion together with the building roof panel after being attached in advance to the building roof panel. Is essentially different from the attic shield member of the present invention attached to the roof. Ventilation spacers are attached to a part of a single roof panel for building, and have ventilation function. However, the ventilation spacers cannot be connected to each other. There is no.

  Even if it is assumed that only the ventilation spacer is attached to the roof, it cannot be used for renovation because it cannot be attached with the field plate attached when it is joined only to the rafter that corresponds to the rafter. . When it is attached to the roof of an existing building for renovation, it is necessary to attach it to the face material corresponding to the base plate using a fastening material such as staples or nails, and a gap is always generated in the portion where the fastening material is attached. Therefore, rainwater may infiltrate or leak from the gap.

  As described above, although an attic shield member for the purpose of preventing rainwater infiltration or leakage, or forming an insulating layer to avoid an increase in indoor temperature, is disclosed, it satisfies all functions simultaneously. Is not disclosed. In addition, all are only for new buildings and cannot be easily applied to renovation of existing buildings.

  In view of the above problems, the present invention is an attic shield member that prevents infiltration and leakage of rainwater, and prevents an increase in indoor temperature by forming a heat insulating layer on the attic, It is an object of the present invention to provide an attic shield member that can be used for renovation of buildings and can provide waterproofing and heat insulation regardless of the interval between rafters.

  In order to solve the above-mentioned problems, an attic shield member for a wooden building according to claim 1 of the present invention is characterized in that both rising wall portions erected by bending upward from both side ends of the groove portion, and both An attic shield member comprising a mounting edge provided with a crease from the upper end of the rising wall and bent outward, both of the groove and the rising wall, and the rising wall and the mounting edge. It becomes flexible at the crease.

  The attic shield member for a wooden building according to claim 2 is the attic shield member for a wooden building according to claim 1, wherein the length of the mounting edge in the front-rear direction is shorter than the length of the groove in the front-rear direction. The mounting edge front end and the groove front end are formed obliquely.

  Claim 3 is an attic shield member for a wooden building according to claim 1 or claim 2, wherein the width of the mounting edge in the left-right direction is wider than the distance between the upper and lower ends of the rising wall. It is characterized by becoming.

  According to a fourth aspect of the present invention, in the attic shield member for a wooden building according to the first to third aspects, the groove portion has one or a plurality of downward folds. It is an attic shield member of the wooden building of any one of Claim 3.

  A fifth aspect of the present invention is the attic shield member for a wooden building according to any one of the first to fourth aspects, wherein the shield member is made of a plastic corrugated cardboard material.

  The attic shield member of the wooden building of the present invention has a shape in which a rising wall portion and a mounting edge portion are provided on the left and right sides of the groove portion, respectively, so that the mounting edge portion is attached to the top surface of the rafter at the time of new construction. be able to. The angle formed by the groove and the rising wall and the angle formed by the rising wall and the mounting edge can be arbitrarily changed. Therefore, when renovating an existing building, the mounting edge is configured to face the rafters adjacent to each other. It can be easily attached as if it were joined. Therefore, the attic shield member of the present invention can be easily applied to a new building or a renovation of an existing building.

  Moreover, even if the space | interval between adjacent rafters differs, this invention can be attached by adjusting the angle which the groove part and the rising wall part make, and the angle which the rising wall part and the attachment edge part form. In addition, since the mounting edge is a rectangular parallelepiped shape and not an inverted U shape, it is not necessary to create the edge separately according to the size of the rafters. Even if the present invention is made in a single size and shape, it can be applied to various buildings, and can be provided at low cost by mass production.

  The attic shield member of the present invention forms a space in the attic together with the field board. By connecting the attic shield member of the present invention along the rafters, the space has openings only at two places near the eaves girder at the lower end of the roof and near the purlin at the top of the roof, and other parts are sealed. Become. Even if rainwater infiltrates or leaks through the field plate, the rainwater is received by the groove portion of the present invention, so that it is possible to prevent indoor leakage. Thereafter, rainwater is discharged from the vicinity of the eaves girder through the space to the outside, so that the surroundings of wood such as girders, rafters and field boards are maintained at a low humidity.

  Moreover, even if the roof is heated by the radiant heat from the sun, since the space exists, heat conduction to the inside can be prevented. Although the air in the space is heated, the air then rises in the space and is released to the outside from the vicinity of the purlin. By these actions, an increase in indoor temperature is avoided.

  Due to the above-described waterproofing and heat insulating functions, wood such as girders, rafters, and field boards are kept dry, and the occurrence of decaying fungi is suppressed, so that the useful life of the building can be extended.

  Since the attic shield member of the present invention does not need to be attached to the base plate with a fastening material such as a nail or staple, the attachment portion of the fastening material is not generated more than necessary on the base plate that is easily exposed to rainwater, It is possible to prevent rainwater from infiltrating or leaking from the gap between the attachment sites.

  In order to reliably prevent rainwater infiltration or water leakage, it is effective to connect a plurality of attic shield members and overlap a part of the grooves of adjacent attic shield members. In the attic shield member according to claim 2, since the length in the front-rear direction of the attachment edge is shorter than the length in the front-rear direction of the groove, it is possible to attach a part of the groove without overlapping the attachment edge. Is possible. If the present invention is continuously arranged on the upper surface of the rafter of the new building so that the mounting edges are in contact with the front and rear ends of the rafter, it is possible to avoid the formation of irregularities on the rafter and to attach the field board to the same level. Since an extra gap does not occur, infiltration or leakage of rainwater can be avoided more effectively.

  In the attic shield member according to claim 3, since the width in the left-right direction of the attachment edge is longer than the distance between the upper and lower ends of the rising wall part, when joining the attachment edge to the side surface of the rafter, the groove part and The rising wall does not interfere with the work, and the installation work for renovation is easy.

  When the attic shield member according to claim 4 is used, since the groove portion has a fold so as to be recessed downward, even when the amount of rainwater that has infiltrated or leaked is small, rainwater tends to collect near the fold due to the inclination. Can be efficiently discharged. As a result, the space formed by the present invention and the field plate and the periphery of the wood such as girders, rafters, and field plates can be kept dry, which contributes to the prevention of the growth of decaying fungi.

  The attic shield member according to claim 5 has a sufficient strength while being lightweight by using a plastic cardboard material as a material. It is difficult to be deformed by radiant heat from the sun and does not corrode, so it can be used for a long time. Since it has water repellency, it has a high ability to discharge rainwater, and it is possible to keep wood such as rafters and field boards in a more dry state.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings showing embodiments. The present invention is not limited to the present embodiment.

The groove portion X is lowest at the fold 1C. When the attic shield member of the present invention is attached and constructed, even if rainwater infiltrates or leaks through the field plate, rainwater can be efficiently collected near the fold, so that rainwater can be efficiently discharged outdoors. .

  The number of folds 1C is not necessarily limited to 1 and may be plural. However, if too many folds are formed, the strength of the attic shield member may be reduced. Therefore, it is preferable that about 1 to 3 creases are provided.

As in the first embodiment, the rising wall portions 1 and 1 have a right trapezoidal shape bent at the folds 1A and 1A, and the longer bases are in contact with both side ends of the groove portion X. The rear end of the portion 1 is on the same line as the rear end of the groove X in the developed view.
The front ends 1a and 1a of the rising wall portions 1 and 1 are formed in a straight line having an inclination that gradually increases toward the rear, and the front ends 2a and 2a of the mounting edge portions 2 and 2 are formed in parallel with the rear end. Yes.

  At the upper ends of the rising wall portions 1 and 1, mounting edge portions 2 and 2 that are symmetrical to each other are provided so as to be freely bent at the folds 1B and 1B. The attachment edge portion 2 has a rectangular parallelepiped shape, and the left and right ends thereof are parallel to the ridge lines at both left and right ends of the groove portion X, and the front and rear ends are parallel to the front and rear ends of the groove portion X. The length L2 in the front-rear direction of the attachment edge 2 is formed shorter than the length L1 in the front-rear direction of the groove X. When the attachment edges 2 and 2 are locked and joined on the rafter, the groove X overlaps even if the attachment edges 2 of adjacent attic shield members are attached so that the front and rear ends thereof are in contact. Since it can be mounted flush with the top surface of the rafters while achieving a higher sealing performance, it provides a higher level of waterproofing even after the field board is attached.

It is a front view which shows an example. FIG. 4 is a cross-sectional view showing an installation example of the attic shield member shown in Example 1 in the case of renovation, and (b) is an illustration of the attic shield member shown in Example 1 in the case of a new construction. It is an oblique view sectional view which shows the example of attachment construction.

  When the present invention is attached to an existing building for renovation, as shown in FIGS. 3 (a) and 4 (a), the present invention is attached to the opposite side surfaces of two rafters 3, 3 adjacent to each other. Attach the edges 2 and 2 together. The means for joining is not particularly limited, but it is preferably attached by fastening materials 4,... Such as nails and staples in order to achieve sufficient joining strength.

  A plurality of the attic shield members of the present invention can be used in series. When the rear end of the attachment edge 2 of the first attic shield member S1 is attached so as to be in contact with the front end of the attachment edge 2 of the second attic shield member S2, the second attic shield member S2 Part of the vicinity of the front end of the groove X overlaps with the vicinity of the rear end of the groove X of the first attic shield member S1. When rainwater infiltrates or leaks through the field board attached on the present invention, rainwater flows down from the second attic shield member S2 to the first attic shield member S1. Even when three or more attic shield members are used, this phenomenon is repeated, so that rainwater is carried to the vicinity of the eaves girder and discharged to the outdoors.

  When attaching the present invention to a new building, as shown in FIGS. 3 (b) and 4 (b), the attachment edges 2 and 2 of the present invention are engaged with the upper surfaces of the two rafters 3 and 3 adjacent to each other. Stop and join. The means for joining is not particularly limited, but it is preferably attached by fastening materials 4,... Such as nails and staples in order to achieve sufficient joining strength.

  A plurality of the attic shield members of the present invention can be used in series. When the rear end of the attachment edge 2 of the first attic shield member S1 is attached so as to be in contact with the front end of the attachment edge 2 of the second attic shield member S2, the second attic shield member S2 Part of the vicinity of the front end of the groove X overlaps with the vicinity of the rear end of the groove X of the first attic shield member S1. When rainwater infiltrates or leaks through the field board attached on the present invention, rainwater flows down from the second attic shield member S2 to the first attic shield member S1. Even when three or more attic shield members are used, this phenomenon is repeated, so that rainwater is carried to the vicinity of the eaves girder and discharged to the outdoors.

  When the length in the front-rear direction of the attachment edge 2 is equal to the length in the front-rear direction of the groove X, in order to overlap the groove X of the adjacent attic shield member, the attachment edge 2 must also be overlapped, Unevenness due to the overlap occurs on the upper surface of the rafter. For this reason, the field board cannot be attached to the same plane, and a gap is generated due to the unevenness, and rainwater may infiltrate or leak. In the present invention, since the length in the front-rear direction of the mounting edge 2 is shorter than the length in the front-rear direction of the groove X, rainwater can be prevented from infiltrating or leaking without causing the above irregularities.

Construction example 2

  FIG. 5 is a side sectional view showing a construction example of a roof of a new building using the attic shield member shown in the first embodiment.

  As shown in FIG. 5, in the frame construction method, a purlin 6 is provided between a parallel purlin (not shown) and an eaves girder 5 in parallel with them, and then the upper part of the purlin, eaves girder, and purlin girder The rafters 3 are provided in the direction perpendicular to the girders. Attic shield members of the present invention are attached to the rafters 3 adjacent to each other. After that, a field board 7 is attached, a waterproof sheet 8 such as asphalt roofing is attached, and a roof material 9 such as a tile is further provided.

  Conventionally, attempts have been made to prevent rainwater from infiltrating or leaking only with the roofing material 9 and the waterproof sheet 8, but rainwater is infiltrated from a small gap in the field plate, which occurs in a fastening material attaching portion such as a nail or a staple. There is a risk of water leakage. According to the present invention, even if rainwater infiltrates or leaks from the field board, rainwater collects in the groove X and is discharged to the outside, so that it is avoided that the wood such as indoors and girders, rafters, field boards, etc. become humid. it can.

  Further, as shown in FIG. 5, when a plurality of attic shield members are arranged in the present invention, the space formed between them and the field board reaches from the eaves girder to the purlin. Even if the roofing material is warmed by the radiant heat from the sun, since the space exists, the indoor temperature rise is suppressed by heat conduction. Since the air heated in the space rises in the space and is discharged from the vicinity of the purlin to the outdoors, the indoor temperature rise is also suppressed thereby.

  As mentioned above, when the attic of a wooden building is constructed using the present invention, rainwater can be efficiently discharged outdoors, and wood such as girders, rafters, and field boards can be kept dry. it can. Since the air permeability is also high, the propagation of decaying fungi can be suppressed and the decay of wood can be avoided, so that the useful life of the building can be extended.
