Description

Technical Field

[0001] The present invention relates to a corner post receiving member for forming a ventilation layer above a corner post in a wooden house.

Background Art

[0002] Conventionally, in a general gabled wooden house, the upper parts of the corner posts and the vertical posts are on the same plane and receive the rough plywood. At this time, since both sides of the corner post are independent spaces, ventilation does not occur at the upper part of the corner gable, and air stays, making it easy for the temperature and humidity to rise.

[0003] Especially in recent years, in housing-intensive areas such as big cities, in order to secure the right to sunlight of the neighboring land on the north side, the building height is often restricted, and a pitched ceiling or a lowered main roof is often adopted. In a pitched ceiling or a lowered main roof, since the space directly under the roof becomes a living space, the rise in temperature in the corner gable part has a great influence on the living space.

[0004] As a structure for providing a ventilation path along the corner post, the structures described in Patent Documents 1 and 2 are known.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In Patent Document 1, it is described that a notch is made in the corner post to form an air flow path, but it is necessary to notch the corner post into a special shape, which results in high costs. Furthermore, Patent Document 2 describes a configuration in which a ventilation material is placed on top of the corner rafter, but the roof sheathing is offset by more than the width of the corner rafter and supported by the rafter. And because the roof sheathing has a special processing shape, it is difficult to form it using a pre-cutting machine and it needs to be processed on site.

[0007] This invention was made in view of the above points, and aims to provide a corner rafter support material that can easily and inexpensively form a ventilation layer on top of the corner rafter. [Means for solving the problem]

[0008] The present invention provides a corner rafter support material for the roof structure of a wooden house, which is placed on a corner rafter to support the roof sheathing plywood, and which consists of two parallel support material bodies, each rectangular in both plan and cross-sectional views, and a sheet material that is placed between the bottom surfaces of the two parallel support material bodies and adhered to each of the support material bodies. The sheet material is cuttable, and the two support members can be separated by cutting the sheet material between the two support member bodies. One or more parallel grooves may be provided on the bottom surface of the support body.

[0009] Furthermore, the present invention provides a ventilation structure for the upper part of a hip rafter in the roof structure of a wooden house, characterized in that a hip rafter support member of the present invention is placed on the upper surface of the hip rafter, the roof sheathing plywood is supported on the upper surface of the hip rafter support member, and a ventilation layer is formed between the upper surface of the hip rafter and the lower surface of the roof sheathing plywood. The upper surface of the rafter fixed to the side of the hip rafter may be above the upper surface of the hip rafter, and the upper surface of the rafter may support the roof sheathing plywood. At the intersection of the two corner rafters and the ridge beam, the corner rafter support members, which are placed on the upper surface of each corner rafter, may be made by cutting the sheet material between the two support member bodies to divide it into two support members, and arranging the two support members offset from each other so that the distance between the end faces where the two corner rafters meet and the ends of the two support members is approximately equal. [Effects of the Invention]

[0010] The present invention has at least one of the following effects. <1> By forming a ventilation layer on the upper part of the corner post, it is possible to prevent the temperature and humidity from rising due to the stagnation of air in the upper part of the corner column. <2> A ventilation layer can be formed simply by arranging a corner post receiving member on the corner post, and no processing of the corner post is required.

Modes for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described in detail while referring to the drawings.

Embodiment

[0013] <1> Outline of the ventilation structure at the upper part of the corner post The ventilation structure at the upper part of the corner post of the present invention forms a ventilation layer V at the upper part of the corner post by arranging a corner post receiving member 1 on the upper surface of the corner post 2 and receiving the field plywood 3 (Figs. 1, 2). A plurality of corner post receiving members 1 are arranged with a gap S of 100 to 150 mm provided in the longitudinal direction of the corner post.

[0014] <2> Corner post receiving member The corner post receiving member 1 is composed of two parallel receiving member bodies 11 and a sheet material 12 connecting the receiving member bodies 11 (Figs. 3, 4) The receiving member body 11 is a long member made of resin or wood, rectangular in plan view and cross-sectional view. The receiving member body 11 is provided with one or a plurality of parallel grooves 111 in the longitudinal direction of the bottom surface. Two receiving member bodies 11 are arranged in parallel at a predetermined interval, and a sheet material 12 is disposed across the bottom surfaces thereof. The sheet material 12 is adhered and connected to each receiving member body 11. The receiving member body 11 and the sheet material 12 are cuttable, and by cutting, the length of the corner receiving member 1 can be adjusted on site.

[0015] <3>Ventilation layer Since the two receiving member bodies 11 of the corner receiving member 1 are connected by a foldable sheet material 12 at a predetermined interval, when the corner receiving member 1 is disposed on the upper surface of the corner beam 2, each receiving member body 11 can be disposed along the inclined surface of the upper surface of the corner beam 2. The groove 111 provided on the lower surface of the receiving member body 11 serves as an anti-slip measure to prevent dropping when the corner receiving member 1 is temporarily disposed on the upper surface of the corner beam 2. Also, since the anti-slip measure is the groove 111, it is easy to adjust the arrangement position. The width of the receiving member body 11 is configured to be shorter than the width of the inclined surface of the upper surface of the corner beam 2. Then, the purlin 4 disposed on the side surface of the corner beam 2 raises the upper surface by a height (for example, 12 mm) from the upper surface of the corner beam 2, and receives the rough plywood 3 with the upper surface of the receiving member body 11 and the upper surface of the purlin 4 being in the same plane. By configuring in this way, a ventilation layer V surrounded by the upper surface of the corner beam 2, the lower surface of the rough plywood 3, the side surface of the corner receiving member 1, and the purlin 4 is formed. By simply disposing the corner receiving member 1 on the corner beam 2, no processing of the corner beam 2 is required, and the ventilation layer V can be easily formed on the upper part of the corner beam 2 at a low cost. By forming the ventilation layer V on the upper part of the corner beam 2, it is possible to prevent an increase in temperature and humidity due to air stagnation in the upper part of the corner gable. Particularly in the case of a pitched ceiling or an under-roof space, by being ventilated by the ventilation layer V in the upper part of the corner beam 2, an increase in temperature of the corner gable can be prevented, and the influence on the living space can be reduced.

[0016] <4>Arrangement form of the corner receiving member at the uppermost part of the corner beam At the intersection of the two corner rafters 2 with the uppermost ridge beam 5, the sheet material 12 between the support body 11 of the corner rafter support material 1, which is placed on the upper surface of each corner rafter 2, may be cut to divide it into two support body 11. The two support body 11 may then be offset so that the distance between the end faces where the two corner rafters 2 meet and the ends of the two divided support body 11 are approximately equal (the gap between the support body 11 placed on both sides is about 20 mm).

[0017] <5> Fixing the corner rafter support with nails The corner rafter support member 1 is secured with two nails 7 for each support member body 11, for a total of four nails 7. At this time, nails 7 are driven into the parts other than the rafter 4 width to secure the plywood 3, so that the nails 7 do not interfere with the nails that secure the roof sheathing 3.
