Description

In this invention, in a building such as a house, when a roofing material or an outer wall material is attached using a nail or a screw, a waterproof plate is interposed between the exterior material and the wooden base, and the wooden base and the external material are interposed. The present invention relates to a method for attaching an exterior material to provide air permeability.

  Conventionally, when attaching, for example, a roofing exterior material in a wooden house, the following work process has been performed. First, from the top of the wooden rafters that make up the framework of the roof, nailing and fastening a sheet-like underlay, and then nailing or tacking a sheet-like waterproof base material from there, and then from the top surface Was nailed and stopped, and finally the roofing exterior material was sown and nailed. In addition, the roof exterior material may be attached directly to the roof base without using the tiles. In this case, a hole is made in the roof exterior material in advance, and a nail is driven into the base plate etc. and fixed. It was.

  There are various materials such as roofing, colonial firing, single firing, metal plate firing, slate firing, etc., as roofing exterior materials, all of which were attached to a wooden base using nails. A waterproof sheet is interposed between the roof exterior material and the wooden base to prevent permeation of rainwater and the like that cannot be compensated for by the roof exterior material. Conventional waterproof base materials are generally waterproof paper in which tar or asphalt is infiltrated into felt paper, or a sheet material made of a synthetic resin such as plastic or vinyl.

  However, the nail for attaching the roofing exterior material is driven through the waterproof sheet covering the surface of the wooden base, so that there is a hole in the waterproof sheet, which may impair the waterproof performance of the waterproof sheet. Also, there is a problem that rainwater and the like easily enter from around the nails.

  In addition, there is a part called “Karabana” at the edge of the roof, and here the following structure was adopted. Mount a climbing tree along the flow direction of the roof, and attach a waterproof sheet on the top of the field board, including the top of the climbing tree, and the exterior of the roof. It was covered with drainage and covered with a waterproof sheet from the upper part corresponding to the climbing tree. The climbing tree has been used by preserving wood that has been formed long along the roof flow direction. In addition, the drainage was made by processing a thin metal plate and had a cross-sectional structure for wrapping a climbing tree.

  However, rainwater or the like sometimes penetrated the climbing tree along the nail that fixed the drainer to the climbing tree. In addition, the climbing tree gradually faded due to repeated wet and dry, and sometimes the nail lifted up. For this reason, there have been problems such as retightening of nails and replacement / repair of climbing trees. The nail lift accompanying the thinning of the wood may occur in the general part of the roofing exterior material.

In order to improve the various problems that occur when nailing the exterior material in this way, for example, the following conventional techniques have been proposed.
JP-A-7-300948 JP-A-9-328871 JP, 2001-254491, A Here, in patent documents 1, by attaching a waterproofing material beforehand to the part which contacts the roof ground surface of the nail nailing part used for attaching the exterior material for roof to a wooden ground, A structure for preventing water leakage from a nail hole has been disclosed. Waterproof material is a sheet of material that retains waterproof properties even when the nail penetrates, such as asphalt felt, urethane-based, acrylic-based, silicone-based sealing materials, water-absorbing resin, synthetic rubber, etc. Or it formed in ring shape, plate shape, etc.

Patent Document 2 discloses a sheet material in which a waterproof base material is formed of a resin composition containing thermoplastic rubber and a thermoadhesive resin as essential components. This is to maintain elasticity in the entire material of the waterproof base material, and thereby the gap around the penetrating nail is restored and pressed, so that the entry of rainwater can be prevented.

  Patent Document 3 discloses a structure in which a metal plate is attached instead of a wooden base material. This is because the part that was made up of the traditional driftwood and peltier drainer, the pelbar part that is long in the roof flow direction, the top plate part that covers the upper part of the basin part and the outer panel that covers the outside of the roof It is changed to the insertion plate part that is sandwiched between the top and bottom of the waterproof sheet and the roof material above it on the inner side of the part and its roof, which is formed with a thin metal plate and can be screwed in any place with screws or nails It was a configuration.

  However, the conventional structure in which the waterproof material is attached only to the portion that contacts the lower ground of the nailing portion has poor versatility, and cannot be applied at all to other roof materials and outer wall materials. In addition, since the conventional waterproof sheet material used a flexible material, if there is unevenness in the wooden base, there is no effect of straightening this, and the fine uneven shape of the base is reflected on the exterior surface There was a fear. Moreover, in the structure using a metal plate instead of the wooden base, the degree of freedom is small, and it cannot be widely applied to general buildings, for example, each component mounting position of a roofing material, an outer wall mounting portion, and the like.

  In addition, when a flat exterior material is directly attached to a wooden base surface such as a colonial method, there is a drawback that the exterior material and the base surface are in close contact with each other, resulting in poor air permeability. When such a close contact structure is adopted for the roofing material, there is a possibility that rainwater that has infiltrated from the nail hole may stay.

The present invention was made to solve the above-mentioned problems of the conventional exterior material mounting method, and can be used to attach a general building exterior material widely at an arbitrary location. Using a waterproof board for mounting exterior materials that prevents penetration of the wooden base, prevents thinning of the wooden base as much as possible, and prevents the nail from lifting up. It aims to provide a method.

In order to solve the above-described problems, the exterior material mounting method of the present invention is a belt-like plate material interposed between a wooden base and the exterior material when the exterior material is attached to the wooden base of a building using nails or screws. A waterproof panel for mounting exterior materials, which is made by sticking metal nails that can be nailed on both sides of an intermediate material made of a nailing material that has at least waterproof performance and elastic force to restore Arranged in parallel on the ground surface, the exterior material is placed so that the nail position is overlapped with this waterproof board, and the exterior material is attached from the top surface of the exterior material using nails or screws. A gap that allows ventilation is provided between the two.

  As the intermediate material, for example, a rubber-based plate material is used, and this is sandwiched between thin metal plates. These easily penetrate the nail and seal the periphery of the nail with the restoring force of the intermediate material to prevent the penetration of rainwater, and at the same time, prevent the nail from moving in the direction of pulling out by deformation by punching a metal plate.

  When the roofing material is attached, the waterproof plate material flows from the ridge toward the eaves direction, and when the wall material is attached, it is arranged in the rising direction. The gap is set so that air can flow in from one end of the exterior material and flow out from the other end.

Since the waterproof material for attaching the exterior material uses a material having waterproof performance and restoring force for the intermediate material, rainwater can be prevented from penetrating into the wooden substrate through the nail. For this reason, it is possible to prevent the wooden base from fading due to the moisture absorption / drying cycle as much as possible, and to prevent the nail from lifting. Moreover, since the metal thin plate which can be nail | punched on both surfaces is provided, even if there is unevenness in a wooden base | substrate, this can be corrected evenly.

  Further, since the nail driven into the metal thin plate is not likely to come off due to secular change, the necessity for retightening the nail or replacing / repairing the wooden base is drastically reduced. Moreover, since the waterproof board can be cut at an arbitrary length, it can be applied according to the location where the exterior material is attached to the wooden base by nailing. That is, it can be cut and used in accordance with a wide variety of general building exterior materials, for example, each component of the roofing material, the outer wall member, and each mounting portion.

According to the exterior material mounting method of the present invention , a waterproof plate is interposed between the wooden base of the building and the external material, and an air permeable gap is provided, so that the ventilation performance is improved and the deterioration of the wooden base can be prevented. Further, even when a flat exterior roofing material is attached to a wooden base surface, the infiltrated rainwater can be discharged without stagnation.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a cross-sectional view of a roof using a waterproof board, FIG. 2 is a cross-sectional view of a waterproof board for mounting an exterior material, and FIG. 3 is a plan layout view of the roof. On a wooden rafter (not shown) constituting the frame of the roof, a water-resistant plywood base plate 1 (field base plate) is nailed and fixed, and a waterproof sheet 2 is pasted thereon, and a strip-like plate is formed thereon. The waterproof plate material 3 is placed, and a flat roof material 4 is fixed by using a nail 5. The roof material 4 has a substantially house shape, and a plurality of nailing holes 4a are provided as nailing portions in the upper half.

  The strip-shaped waterproof plate 3 is made by attaching metal thin plates 7 and 7 to both surfaces of an intermediate member 6 made of a rubber-based plate. The intermediate member 6 has waterproof performance and elastic force to restore and can be nailed. The right material. The waterproof plate 3 easily penetrates the nail 5 and seals the periphery of the nail 5 by the restoring force of the intermediate member 6 to prevent rainwater from penetrating, and at the same time, the nail 5 is deformed by punching the metal thin plate 7. Hug.

  As the metal thin plate 7, for example, a rust-proof metal plate such as aluminum or stainless steel is used. As a whole, the waterproof board 3 is a member having both surfaces that are smooth and rigid enough not to be easily deformed by a normal mounting operation. The thickness of the thin metal plate 7 is appropriately set so that the nail 5 can penetrate.

  The width of the waterproof plate 3 may be about 3 cm, for example, as long as the punched portion of the nail 5 can be waterproofed. However, when the nail 5 is arranged in a staggered manner as shown in FIG. Also, a large panel-shaped plate material may be appropriately cut according to the size of the installation location.

  When the roofing material 4 is constructed using the waterproofing plate material 3 formed as described above, the waterproof sheet 2 is pasted on the base plate 1 in advance, and the belt-shaped waterproofing plate material is matched to the nail-placed portion of the roofing material 4. 3 are arranged in parallel, a roof material 4 is placed thereon, a nail 5 is driven through a nail hole 4a, and the waterproof board 3 is penetrated and fixed to the base plate 1.

  A gap corresponding to the thickness of the waterproof plate 3 is continuously formed between the roofing material 4 and the base plate 1. For example, air flowing from the eaves is exhausted from the building. The rainwater that has infiltrated from the nail hole 4a is immediately discharged through this gap.

  Moreover, since the waterproof board 3 is smooth, even if the ground board 1 is uneven, it can be corrected. Further, since the nail 5 driven into the metal thin plate 7 is not likely to come out, it is unnecessary to retighten the nail.

  The waterproof board material of the present invention is not limited to the installation location of general roofing materials, but if it is at the edge of the roof, the nails are widely applied to the wooden base of the building, such as the ridge part at the top, the joint part to which the outer wall material is attached, etc. If it is a location which uses and attaches an exterior material, it can be used in arbitrary locations.

It is sectional drawing of the roof which uses a waterproof board material. It is sectional drawing of the waterproof board material for exterior material attachment. It is a plane arrangement view of a roofing material.
