Description
【０００１】[0001]
この考案は、外壁パネル間に形成される目地に乾式目地工法で施される外壁の 目地構造に関するものである。 This invention relates to a joint structure of an outer wall which is formed by a dry joint method on a joint formed between outer wall panels.
【０００２】[0002]
従来、図６に示すように、一対の外壁パネル３１，３１の外壁材３２，３２間 に形成される目地３３は、バックアップ材３４と湿式シーリング材３５とによる 湿式シーリング工法で水密処理している。３６は外壁下地材である。 Conventionally, as shown in FIG. 6, joints 33 formed between outer wall members 32, 32 of a pair of outer wall panels 31, 31 are watertightly treated by a wet sealing method using a backup material 34 and a wet sealing material 35. .. Reference numeral 36 is an outer wall base material.
【０００３】[0003]
しかし、湿式工法であるため、次の各種の問題点がある。すなわち、ａ．施工 時期が天候に左右されて工期が長くなる。ｂ．専門の職人が必要になるうえ、汚 れ作業であるため、職人の確保が難しい。ｃ．品質が職人の腕により左右して安 定しない。ｄ．外壁材３２の伸縮によりシーリング材３５が切れることがある。 However, since it is a wet method, it has the following various problems. That is, a. The construction period depends on the weather, and the construction period becomes longer. b. Specialized craftsmen are required, and it is difficult to secure craftsmen because it is a dirty work. c. The quality depends on the skill of the craftsman and is not stable. d. The sealing material 35 may be broken due to the expansion and contraction of the outer wall material 32.
【０００４】 このため、乾式目地工法が種々試みられているが、単に弾性シール材を目地溝 に圧入する等の構造では、確実な水密性を得ることが難しい。For this reason, various dry joint construction methods have been tried, but it is difficult to obtain reliable water tightness with a structure in which an elastic seal material is simply press-fitted into a joint groove.
【０００５】 この考案の目的は、工期の短縮、専門職の不要化、品質の安定、および外壁材 の伸縮によるシール切れの防止が図れる外壁の目地構造を提供することである。An object of the present invention is to provide a joint structure for the outer wall, which can shorten the construction period, eliminate the need for a professional, stabilize the quality, and prevent the seal from breaking due to the expansion and contraction of the outer wall material.
【０００６】[0006]
この考案の外壁の目地構造は、各々パネルフレームの屋外面に外壁下地材を介 して外壁材を張付けた一対の外壁パネルを、柱の両側に並設した外壁に適用され る。このような外壁において、外壁材の側縁を前記柱の前方へ延出させると共に 、外壁下地材を外壁材よりも幅狭に貼りひかえる。前記柱の屋外面には、弾性体 からなる内側シール材を貼付け、この内側シール材は両リップ部が両外壁パネル の外壁材の裏面に各々接触する断面略Ｃ字状のものとする。両外壁パネルの外壁 材間には弾性体からなる外側シール材を嵌合させる。 The joint structure of the outer wall of the present invention is applied to the outer wall in which a pair of outer wall panels each having an outer wall material attached to the outdoor surface of the panel frame are attached to both sides of the column. In such an outer wall, the side edge of the outer wall material is extended to the front of the pillar, and the outer wall base material is attached narrower than the outer wall material. An inner sealing material made of an elastic material is attached to the outdoor surface of the pillar, and the inner sealing material has a substantially C-shaped cross section in which both lip portions contact the back surfaces of the outer wall materials of both outer wall panels. An outer sealing material made of an elastic material is fitted between the outer wall materials of both outer wall panels.
【０００７】 前記内側シール材は、両リップ部の内面に、先端が内側シール材のウエブ部に 当接する弾性補強脚を一体に設けたものであっても良い。The inner sealing material may have elastic reinforcing legs integrally provided on the inner surfaces of both lip portions, the tips of which contact the web portion of the inner sealing material.
【０００８】[0008]
この構成によると、一次シールとなる外側シール材と外壁材との間から雨水が 浸入しても、二次シールとなる内側シール材で屋内への浸入が阻止され、確実な シール性能が得られる。前記の外側シール材の内側に浸入した雨水は、内側シー ル材内の縦樋状の空間を流下して排出される。内側シール材は、断面略Ｃ字状の 弾性体からなり、リップ部が外壁材の裏面に接して止水面を形成するため、外壁 材の伸縮による目地幅の狂いにも対応でき、シール切れが防げる。 施工に際しては、内側シール材を柱に貼り付けておき、外壁パネルを建込むだ けで、内側シール材の施工が完了する。外側シール材は、外壁パネルの建込み後 に取付ける。 According to this configuration, even if rainwater enters between the outer seal material that serves as the primary seal and the outer wall material, the inner seal material that serves as the secondary seal prevents the entry of indoor water, and reliable sealing performance can be obtained. .. The rainwater that has entered the inside of the outer seal material flows down through the space of the inner seal material in the form of a gutter and is discharged. The inner sealing material is made of an elastic body with a roughly C-shaped cross section, and the lip part contacts the back surface of the outer wall material to form a water stop surface, so it is possible to cope with joint width deviation due to expansion and contraction of the outer wall material, and seal breakage will occur. Can be prevented. At the time of construction, the inner sealing material is pasted on the pillar and the outer wall panel is installed, and the construction of the inner sealing material is completed. The outer sealing material is installed after the outer wall panel is installed.
【０００９】 内側シール材のリップ部に弾性補強脚を設けた場合は、内側シール材の弾力が 増大して外壁材裏面との接触圧が増大する。また、外壁材裏面がリップ部に加圧 状態に接触したときにリップ部先端が内側へ撓んで外壁材から離れることが防止 され、一様な面接触が確保される。When the elastic reinforcement leg is provided at the lip portion of the inner seal material, the elasticity of the inner seal material increases and the contact pressure with the back surface of the outer wall material increases. Further, when the back surface of the outer wall material comes into contact with the lip portion under pressure, the tip of the lip portion is prevented from bending inward and separating from the outer wall material, and uniform surface contact is secured.
【００１０】[0010]
この考案の一実施例を図１および図２に基づいて説明する。この外壁の目地構 造は、一対の隣接する外壁パネル１，１間の目地２に適用される。各外壁パネル １は、図２に示すように溝形鋼からなるパネルフレーム３の屋外面に枠状の外壁 下地材４を介して外壁材５を貼付けたものであり、各外壁パネル１のパネルフレ ーム３は角パイプ等からなる柱６に取付けられる。外壁下地材４は、耐水合板等 からなり、外壁材５にはセメント板やスレート板等が用いられる。 An embodiment of this invention will be described with reference to FIGS. The joint structure of the outer wall is applied to the joint 2 between the pair of adjacent outer wall panels 1 and 1. As shown in FIG. 2, each outer wall panel 1 is formed by attaching an outer wall material 5 to an outdoor surface of a panel frame 3 made of channel steel via a frame-shaped outer wall base material 4 and a panel frame of each outer wall panel 1. The boom 3 is attached to a pillar 6 made of a square pipe or the like. The outer wall base material 4 is made of waterproof plywood or the like, and the outer wall material 5 is a cement plate or a slate plate.
【００１１】 各外壁パネル１，１の外壁材５，５は、側縁を柱６の前方に突出させ、外壁下 地材４は外壁材５よりも幅狭に貼り控える。The outer wall members 5 and 5 of each outer wall panel 1 and 1 have side edges protruding forward of the pillar 6, and the outer wall lower base member 4 is narrower than the outer wall member 5 and is not attached.
【００１２】 前記柱６の屋外面に、ゴム等の弾性体からなる断面略Ｃ字状の内側シール材７ を外向きに貼付け、そのリップ部７ａを外壁材５の裏面に弾性的に圧接させる。 隣合う外壁材５，５間の隙間には、化粧仕上げ材を兼用する外側シール材８を圧 入状態に嵌合させる。An inner sealing material 7 having an approximately C-shaped cross section made of an elastic material such as rubber is attached to the outer surface of the pillar 6 outwardly, and its lip portion 7 a is elastically pressed against the back surface of the outer wall material 5. .. An outer seal material 8 which also serves as a decorative finish is fitted into the gap between the adjacent outer wall materials 5 and 5 in a press-fitted state.
【００１３】 外側シール材８は、内向きの略溝形に成形され、ウエブ部から両側に張り出し て外壁材５の端部外面に被さるカバー片８ａを有すると共に、外壁材５の端部内 面に係合する係合片８ｂと、外壁材５の端面に弾性的に圧接する小ひれ部８ｃと が設けられている。The outer sealing material 8 is formed in a substantially inward groove shape, has a cover piece 8 a that projects from the web portion to both sides and covers the outer surface of the end of the outer wall material 5, and the inner surface of the outer wall material 5 has an inner surface. An engaging piece 8b to be engaged with each other and a small fin portion 8c elastically pressed against the end surface of the outer wall member 5 are provided.
【００１４】 この構成の目地構造によると、外側シール材８から雨水が浸入したとしても、 内側シール材７で止水され、内側シール材７内の縦樋状の空間９を流下して排出 される。このように、外側シール材８と内側シール材７とで二重に止水が行え、 確実なシール性が得られる。また、外壁パネル５の伸縮により目地幅に多少の狂 いが生じても、内側シール材７は外壁材５の裏面に接触して止水面を形成するた め、シール切れの問題がない。外側シール材８も断面略溝形の弾性体からなるた め、前記目地幅の狂いに弾性変形で対応でき、シール性の低下が防止される。According to the joint structure of this configuration, even if rainwater enters from the outer seal material 8, the water is stopped by the inner seal material 7, and flows down through the vertical gutter-shaped space 9 in the inner seal material 7 to be discharged. It In this way, the outer sealing material 8 and the inner sealing material 7 can double stop water, and a reliable sealing property can be obtained. Further, even if the joint width slightly varies due to expansion and contraction of the outer wall panel 5, the inner seal material 7 contacts the back surface of the outer wall material 5 to form a water stop surface, so that there is no problem of seal breakage. Since the outer sealing material 8 is also made of an elastic body having a substantially groove-shaped cross section, it is possible to deal with the deviation of the joint width by elastic deformation, and the deterioration of the sealing performance is prevented.
【００１５】 外側シール材８は着脱可能であり、後に取外すことによって目地部のシール性 を点検することができる。また、外側シール材８は、外壁材５がプレコート材の 場合に、外壁材５に対応した色のものに作ることができ、色合せが容易である。The outer sealing material 8 is removable, and the sealing property of the joint can be checked by removing it later. Further, when the outer wall material 5 is a precoat material, the outer seal material 8 can be made in a color corresponding to the outer wall material 5, and the color matching is easy.
【００１６】 施工に際しては、前記のように全て乾式に施工でき、そのため施工時期が天候 に左右されたり、シーリング材の硬化を待つ必要がなく、工期が短縮される。し かも、外壁パネル１の建込みと同時に内側シール材７の施工も完了するので、よ り一層施工が迅速に行える。また、湿式シーリングのような専門職が不要で、安 定した品質が得られ、汚れ作業を伴うこともない。As for the construction, all of the construction can be carried out in a dry manner as described above, so that the construction time can be shortened because it is not necessary to wait for the construction time to depend on the weather or to cure the sealing material. However, since the construction of the inner sealing material 7 is completed at the same time when the outer wall panel 1 is built, the construction can be carried out more quickly. In addition, it does not require professionals such as wet sealing, can obtain stable quality, and does not involve dirt work.
【００１７】 図３および図４は、この考案の他の実施例を示す。この例は、内側シール材７ のリップ７ａの内面に、先端が内側シール材７のウエブ面に当接する弾性補強脚 ７ｂを一体に形成したものである。3 and 4 show another embodiment of the present invention. In this example, an elastic reinforcing leg 7b is integrally formed on the inner surface of the lip 7a of the inner seal material 7 with its tip abutting the web surface of the inner seal material 7.
【００１８】 このように弾性補強脚７ｂを設けた場合、内側シール材７の弾力が増大して外 壁材５の裏面との接触圧が増大し、また弾性劣化に対しても接触圧が維持できる 。しかも、つぎのようにリップ部７ａと外壁材５との接触面が一様となる。When the elastic reinforcing legs 7b are provided in this manner, the elasticity of the inner sealing material 7 increases, the contact pressure with the back surface of the outer wall material 5 increases, and the contact pressure is maintained even when the elasticity is deteriorated. it can . Moreover, the contact surface between the lip portion 7a and the outer wall member 5 becomes uniform as follows.
【００１９】 すなわち、図１の実施例の内側シール材７では、図５（Ａ）に示すように外壁 材５で内側シール材７に圧縮力Ｆを加えると、同図に破線で示すようにリップ部 ７ａの先端が内側へ撓み、そのため止水面となる接触部が線接触状態になる。 しかし、弾性補強脚７ｂが設けてあると、同図（Ｂ），（Ｃ）に示すように、 外壁材５から圧縮力Ｆが加わっても、リップ７ａの先端が内側へ撓むことが防止 され、外壁材５に対する一様な面接触状態が確保される。このように、弾性補強 脚７ｂによって接触圧が増大し、かつ接触が一様化するため、水密性がより一層 向上する。That is, in the inner seal material 7 of the embodiment shown in FIG. 1, when a compressive force F is applied to the inner seal material 7 by the outer wall material 5 as shown in FIG. The tip of the lip portion 7a bends inward, so that the contact portion, which serves as a water blocking surface, comes into line contact. However, if the elastic reinforcing legs 7b are provided, the tip of the lip 7a is prevented from bending inward even when the compressive force F is applied from the outer wall material 5, as shown in FIGS. As a result, a uniform surface contact state with the outer wall member 5 is ensured. In this way, the elastic reinforcing legs 7b increase the contact pressure and make the contact uniform, so that the watertightness is further improved.
【００２０】 また、弾性補強脚７ｂが設けてあると、柱６に接着するときに、内側シール材 ７のウエブ部が柱表面から浮き上がり難くなり、施工が行い易くなる。その他の 構成効果は前記実施例と同様である。Further, when the elastic reinforcing legs 7b are provided, the web portion of the inner sealing material 7 is less likely to be lifted from the surface of the pillar when it is bonded to the pillar 6, and the construction is facilitated. Other structural effects are the same as those of the above-mentioned embodiment.
【００２１】 なお、前記各実施例では外側シール材８を断面略溝形としたが、外側シール材 ８は種々の形状のものが使用できる。Although the outer seal material 8 has a substantially groove-shaped cross section in each of the above-described embodiments, various shapes can be used as the outer seal material 8.
【００２２】[0022]
この考案の外壁の目地構造は、柱に貼付けた断面略Ｃ字状の内側シール材を両 側の外壁パネルの外壁材裏面に接触させると共に、両側の外壁材間に外側シール 材を嵌合したため、全て乾式に施工でき、しかも内側シール材は外壁パネルの建 付けと同時に止水面が形成できる。そのため、施工が容易で工期が短縮され、専 門職が不要で品質も安定する。 また、外壁材の裏面に内側シール材が接触して止水面を形成するため、外壁材 の伸縮による目地幅の狂いに対応でき、シール切れが防止される。 In the joint structure of the outer wall of this invention, the inner seal material having a substantially C-shaped cross section attached to the pillar is brought into contact with the back surface of the outer wall material of the outer wall panels on both sides, and the outer seal material is fitted between the outer wall materials on both sides. All of them can be installed by dry method, and the inner sealing material can form the water blocking surface at the same time as the outer wall panel is installed. Therefore, construction is easy, the construction period is shortened, no professional occupation is required, and the quality is stable. Further, since the inner sealing material comes into contact with the back surface of the outer wall material to form the water stop surface, it is possible to cope with the deviation of the joint width due to the expansion and contraction of the outer wall material and prevent the seal from breaking.
【００２３】 請求項２の目地構造は、内側シール材のリップ部に弾性補強脚を設けたので、 外壁材裏面との接触圧が増大し、また弾性劣化等に対しても接触圧が維持でき、 さらにリップ部先端の撓み変形が防止できて、接触部が一様な面接触状態になる 。これらのため、より一層水密性が向上する。In the joint structure according to the second aspect, since the elastic reinforcing leg is provided at the lip portion of the inner sealing material, the contact pressure with the back surface of the outer wall material increases, and the contact pressure can be maintained even if the elasticity deteriorates. In addition, the tip of the lip can be prevented from bending and deforming, and the contact portion can be brought into a uniform surface contact state. For these reasons, the watertightness is further improved.
