Description
【０００１】[0001]
本考案は建物の外壁の目地構造に関するものである。 The present invention relates to a joint structure of an outer wall of a building.
【０００２】[0002]
従来、外壁の目地部のクラック発生を防止するための外壁の目地構造としては 、実開平２−３２５４７号、実開平２−３９０３６号、実開平２−６８９５１号 等が挙げられる。 Conventionally, as joint structures of the outer wall for preventing the occurrence of cracks in the joints of the outer wall, there are, for example, Utility Model No. 2-352547, Utility Model No. 2-339036, and Utility Model No. 2-68951.
【０００３】[0003]
しかしながら、上記従来の目地構造では、外壁材の目地部に弾性シ−リング材 を充填し、該弾性シ−リング材の表面に弾性クロスを介在した弾性パテ層を形成 し、弾性パテ層の表面に弾性塗料あるいは厚吹塗装を施したものであり、このた め、表面の塗料が弾性塗料の場合、目地部裏面と下地材との接着処理がなされて おらず、外壁材の寸法が変化し易く、クラックの発生を防止できても、目地部に 目やせ（凹み）を発生し易いという問題があり、他方、表面の塗料が非弾性塗料 の場合、外壁材の動きに追随できるのは弾性シ−リング材であって、非弾性塗料 が硬性であるため外壁材の寸法変化に追随できずクラックを生じ易いという問題 を有していた。 また、外壁材を下地材に接着剤を介すことなく単に釘又はビスで止着した場合 には、外壁材の目地部の釘又はビスの止着部に外壁材の伸縮時の伸縮応力が集中 してクラックが入り易いという問題を有していた。 そこで本考案は、外壁材が伸縮傾向を生じても外壁材の動きを下地材により拘 束して目地部の伸縮を防止すると共にその伸縮応力を緩和する外壁の目地構造を 提供し、もって上記の従来技術の問題を解決しようとするものである。 However, in the above-mentioned conventional joint structure, the joint portion of the outer wall material is filled with the elastic sealing material, and the elastic putty layer with the elastic cloth interposed is formed on the surface of the elastic sealing material. The surface coating is made of elastic paint.Therefore, if the surface coating is made of elastic paint, the back surface of the joint and the base material have not been bonded, and the dimensions of the outer wall material may change. Although it is easy to prevent cracks from occurring, there is a problem that it is easy to cause skinning (dents) in the joints. On the other hand, when the surface coating is an inelastic coating, the movement of the outer wall material can follow the movement. As a sealing material, the non-elastic coating material has a problem that it is hard to follow the dimensional change of the outer wall material and is apt to crack because the non-elastic coating material is hard. Also, when the outer wall material is simply fixed to the base material with nails or screws without an adhesive, expansion / contraction stress of the outer wall material at the joints of the joints of the outer wall material during expansion / contraction of the outer wall material is There was a problem that cracks tended to occur when concentrated. Therefore, the present invention provides a joint structure of the outer wall that restrains the expansion and contraction of the joint by restraining the movement of the outer wall material by the base material even when the outer wall material tends to expand and contract, and also reduces the expansion and contraction stress. It is intended to solve the problems of the prior art.
【０００４】[0004]
すなわち、本考案は、外壁材の側端部を合わせた目地部において、該外壁材の 目地部の裏面を接着剤で木質の下地材に接着させると共に、釘又はビスで前記外 壁材の目地部を前記木質の下地材に止着したことを特徴とする外壁の目地構造を 要旨とする第１の考案と、この第１の考案において、目地部の表面に弾性シ−リ ング材又は弾性パテを介在して弾性塗料層を形成した第２の考案を包含するもの である。 That is, according to the present invention, in the joint portion where the side edges of the outer wall material are joined together, the back surface of the joint portion of the outer wall material is adhered to the wood base material with an adhesive, and the joint of the outer wall material is joined with a nail or a screw. In the first invention, the joint structure of the outer wall is characterized in that the joint portion is fixed to the wooden base material, and in the first invention, an elastic sealing material or an elastic member is attached to the surface of the joint portion. It includes a second invention in which an elastic paint layer is formed with a putty interposed.
【０００５】[0005]
このようにした目地構造にあっては、外壁材が伸縮傾向を生じると外壁材に接 着剤により接着した下地材が外壁材の動きを拘束して目地部の伸縮を防止し、そ の際目地部に生じる伸縮応力を木質の下地材で緩和させる。 In this joint structure, when the outer wall material expands or contracts, the base material adhered to the outer wall material with the adhesive restrains the movement of the outer wall material and prevents the joint part from expanding or contracting. The wooden base material is used to relieve the expansion and contraction stress generated in the joints.
【０００６】[0006]
次に、本考案の図１に示す一実施例について説明すると、外壁材１の両側端部 ２、２の表面側には面取り部３及び立上り部４が設けられている。面取り部３の 面取り幅Ｗと面取り深さＤは、適当な長さが必要であって、外壁材１の収縮によ る後記する目地部の目やせを緩和するには或る程度必要であり、例えば、面取り 幅Ｗは２０〜４０mm、面取り深さＤは２〜４mmが適当である。また、面取り幅Ｗ は目地の不陸調整に際して幅が広い方が有利である。また、立上り部４は外壁材 １の厚みの斑による面取り幅Ｗの不揃いをなくすために設けてある。 本例は、この外壁材１、１の隣接する側端部２、２を突き合せ、建物の木質の 下地材５に側端部２、２の裏面を接着剤６で接着させると共に釘７、７で止着し 、表面側の面取部３、３でＶ字状の目地部８を形成し、目地部８には弾性シ−リ ング材９を充填し、弾性シ−リング材９の表面及び外壁材１、１表面には弾性塗 料層１０を形成している。 Next, one embodiment of the present invention shown in FIG. 1 will be described. The chamfered portion 3 and the rising portion 4 are provided on the surface sides of the both end portions 2 and 2 of the outer wall material 1. The chamfering width W and the chamfering depth D of the chamfered portion 3 are required to have appropriate lengths, and are necessary to some extent in order to reduce the seam of the joint portion, which will be described later, due to the contraction of the outer wall material 1. For example, it is suitable that the chamfer width W is 20 to 40 mm and the chamfer depth D is 2 to 4 mm. Further, it is advantageous that the chamfer width W is wide when adjusting the joint unevenness. Further, the rising portions 4 are provided in order to eliminate unevenness of the chamfer width W due to uneven thickness of the outer wall material 1. In this example, the adjacent side ends 2 and 2 of the outer wall materials 1 and 1 are butted, the backsides of the side ends 2 and 2 are adhered to the wood base material 5 of the building with the adhesive 6, and the nails 7, 7, and the chamfered portions 3 and 3 on the front surface side form a V-shaped joint portion 8. The joint portion 8 is filled with an elastic sealing material 9, and the elastic sealing material 9 is attached. An elastic coating layer 10 is formed on the surface and the outer wall materials 1 and 1.
【０００７】 この場合、接着剤６は、例えば酢酸ビニル系、アクリル系、ウレタン系、エポ キシ系等の接着剤が挙げられ、比較的硬質なものが望ましいが、粘着テ−プ等も 利用できる。下地材５は、木材の胴縁、合板等の木質の下地材が適当である。即 ち、外壁材１の伸縮応力が大きくなると、この応力を緩和する。このため、外壁 材１に無用な伸縮応力が発生せず、クラックの発生が防止される。弾性シ−リン グ材９はアクリル系、変性シリコ−ン系、ウレタン系、ポリサルファイト系等の 弾性シ−リング材を用い、外壁材１の伸縮を吸収すると共に目地部８からの雨水 の侵入を防止し、目地部８の縁に跨がって塗布して外壁材１、１の不陸を調整し ている。弾性塗料層１０は、合成ゴム系、アクリル樹脂系等で長期に弾力性を有 する塗料を用いる。In this case, examples of the adhesive 6 include vinyl acetate-based, acrylic-based, urethane-based, and epoxy-based adhesives, which are preferably relatively hard, but adhesive tape or the like can also be used. .. The base material 5 is preferably a wood base material such as a wooden furring strip or plywood. Immediately, when the expansion and contraction stress of the outer wall material 1 increases, this stress is relaxed. Therefore, unnecessary expansion and contraction stress is not generated in the outer wall material 1, and cracks are prevented from being generated. The elastic sealing material 9 is made of an acrylic, modified silicone, urethane, or polysulfite-based elastic sealing material, which absorbs the expansion and contraction of the outer wall material 1 and prevents rainwater from the joint portion 8. Invasion is prevented, and the outer wall members 1 and 1 are adjusted for unevenness by being applied over the edge of the joint portion 8. The elastic paint layer 10 is made of a synthetic rubber-based or acrylic resin-based paint that has elasticity for a long period of time.
【０００８】 このようにした目地構造にあっては、外壁材１が伸縮傾向を生じた場合、外壁 材１に接着剤６を介して固定した下地材５が外壁材１の動きを拘束して目地部８ の伸縮を防止し、外壁材１の伸縮傾向の増大により外壁材の目地部８の伸縮応力 が増大傾向を示すと、木質の下地材５が適度の弾力性を発揮してこの伸縮応力を 緩和する。このため外壁材の目地部８に無用な伸縮応力が発生せず、クラックの 発生が防止される。また、目地部８の弾性シ−リング材９、弾性塗料層１０は弾 力性により上記の伸縮傾向に順応し、目地部８のクラックを防止する。In this joint structure, when the outer wall material 1 tends to expand and contract, the base material 5 fixed to the outer wall material 1 with the adhesive 6 restrains the movement of the outer wall material 1. When the expansion / contraction stress of the outer wall material 1 tends to increase due to the expansion / contraction of the outer wall material 1 being prevented from expanding / contracting, the wood base material 5 exerts an appropriate elasticity to expand / contract. Relieves stress. Therefore, unnecessary expansion and contraction stress is not generated in the joint portion 8 of the outer wall material, and the generation of cracks is prevented. Further, the elastic sealing material 9 and the elastic paint layer 10 of the joint portion 8 adapt to the above-mentioned expansion and contraction tendency due to elasticity, and prevent the joint portion 8 from cracking.
【０００９】[0009]
以上説明したように本考案においては、外壁材が伸縮傾向を生じても、目地部 に接着剤で固着した木質の下地材が外壁材の動きを拘束して目地部の伸縮を防止 できると共に伸縮応力を緩和でき、目地部のクラック、反り上り、凹みを防止で きると共に防水性を向上できる。請求項２の考案においては、更に目地が目立た ない外壁の目地構造とすることができる。 As described above, in the present invention, even if the outer wall material tends to expand and contract, the wooden base material fixed to the joint portion with an adhesive can restrain the movement of the outer wall material and prevent the joint portion from expanding and contracting. The stress can be relaxed, cracks, warpage and dents at joints can be prevented and the waterproof property can be improved. According to the second aspect of the present invention, the joint structure of the outer wall can be made more inconspicuous.
