Description

この発明は、建築物の外壁を構成するパネル間の目地部を閉塞する外壁パネル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 panel that closes a joint portion between panels constituting the outer wall of a building.

近年では、コンビニエンスストア，ファミリーレストラン等のフランチャイズ店や仮設住宅等の建築物の需要が高まっている。これらの建築物は使用期間が限られているものが多いため、その構成部材は解体後も保管，再利用可能な構造となっている。   In recent years, there has been an increasing demand for franchise stores such as convenience stores and family restaurants, and buildings such as temporary housing. Since many of these buildings have a limited period of use, their components can be stored and reused after dismantling.

外壁についても解体後は、保管，再利用可能とするために、複数のパネルを所定の場所に配置させて壁面を構成する構造が採られている。   In order to enable storage and reuse of the outer wall after dismantling, a structure is adopted in which a plurality of panels are arranged at predetermined locations to constitute the wall surface.

ところで、これら外壁を構成するパネルの目地部からの雨水等の水分浸入をどのように防ぐかが問題となっている。   By the way, there is a problem of how to prevent water intrusion such as rainwater from the joints of the panels constituting these outer walls.

パネル間の目地部の水密構造として、例えばパネル間の目地部にコーキング材を充填する構造のものが知られている（例えば、特許文献１参照）。また、別の水密構造として、パネル間の目地部に軟質部を有する目地材を一方のパネル端部に接着した構造のものが知られている（例えば、特許文献２参照）。
実開平５−８９６１２号公報（実用新案登録請求の範囲、図１，図４） 特開平１１−２４７３１４号公報（特許請求の範囲、図１） As a watertight structure of the joint portion between the panels, for example, a structure in which a caulking material is filled in the joint portion between the panels is known (for example, see Patent Document 1). As another watertight structure, there is known a structure in which a joint material having a soft part at the joint part between the panels is bonded to one panel end part (see, for example, Patent Document 2).
Japanese Utility Model Laid-Open No. 5-89612 (Utility Model Registration Request, FIGS. 1 and 4) Japanese Patent Laid-Open No. 11-247314 (Claims, FIG. 1)

しかしながら、前者すなわち実開平５−８９６１２号公報に記載の構造のものは、外壁パネル間の目地部にコーキング材を充填されているため、損傷や老朽化等により外壁パネルを交換する際には、まずコーキング材を剥がし取り、新たな外壁パネルを配置した後、再びコーキング材を充填する必要がある。また、後者すなわち特開平１１−２４７３１４号公報に記載の構造においては、目地材が外壁パネルに接着されているため、これにおいても損傷や老朽化等により外壁パネルを交換する際には、目地材を剥がし取り、新たな外壁パネルを配置した後、再び目地材を接着する必要がある。   However, the former, that is, the structure described in Japanese Utility Model Laid-Open No. 5-89612 is filled with a caulking material in the joint portion between the outer wall panels, so when replacing the outer wall panel due to damage or aging, First, the caulking material must be peeled off, a new outer wall panel is placed, and then the caulking material must be filled again. In the latter case, that is, in the structure described in JP-A-11-247314, the joint material is bonded to the outer wall panel. Even in this case, when replacing the outer wall panel due to damage or aging, the joint material is used. After peeling off and placing a new outer wall panel, it is necessary to bond the joint material again.

したがって、従来のこの種の目地構造においては、いずれも作業に熟練と労力を要する上、コーキング材や目地材自体は再利用不可能であるという問題があった。また、コーキング材や目地材自身が軟質であるため、物理的な力や腐食，紫外線等により劣化や損傷を受け易いという問題もあった。   Therefore, each of the conventional joint structures of this type has a problem that the work requires skill and labor, and the caulking material and the joint material itself cannot be reused. In addition, since the caulking material and the joint material itself are soft, there is a problem that they are easily deteriorated or damaged by physical force, corrosion, ultraviolet rays or the like.

この発明は、上記事情に鑑みなされたのもので、容易に取り付け，取り外しが可能で、かつ、耐久性及び水密性に優れた外壁パネルの目地構造を提供することを課題とする。   This invention is made in view of the said situation, and makes it a subject to provide the joint structure of the outer wall panel which can be attached or detached easily, and was excellent in durability and watertightness.

この場合、目板部６０は、略中央に室外側に開口し長手通しに形成される凹溝６３と、凹溝６３の開口両端部から外壁パネル材１の目地部側端部に向かって延在すると共に、先端部がシール部材５１を介してパネル体１０に当接する一対の目地片６４とによって形成されている。   In this case, the eye plate part 60 has a groove 63 that is open to the outside of the room at a substantially center and is formed in the longitudinal direction, and extends from both ends of the groove 63 toward the joint part side end of the outer wall panel material 1. And a pair of joint pieces 64 whose front ends abut against the panel body 10 via the seal member 51.

上記凹溝６３には、上記目地支持材４０の目地支持片４２に当接すると共に、凹溝６３内に収容される固定部材すなわち固定ねじ１８によって目地支持片４２に固定される底部６３ａが形成されると共に、凹溝６３の両開口端から開口部内方に向かって突出する係合突起６３ｂが形成されている。なお、凹溝６３には、凹溝６３の開口部を目隠しする化粧材６５が着脱可能に取り付けられている。   The concave groove 63 is formed with a bottom 63 a that abuts the joint support piece 42 of the joint support member 40 and is fixed to the joint support piece 42 by a fixing member, that is, a fixing screw 18 accommodated in the concave groove 63. In addition, an engaging protrusion 63b is formed that protrudes from both ends of the groove 63 toward the inside of the opening. In addition, the decorative material 65 which blindfolds the opening part of the ditch | groove 63 is attached to the ditch | groove 63 so that attachment or detachment is possible.

上記化粧材６５は、凹溝６３側に開口を有する断面略コ字状に形成されており、凹溝６３の開口部を目隠しする状態において、開口内に上記固定ねじ１８の頭部を収容すると共に、一対の側片の基端部に凹溝６３の開口端に設けられた係合突起６３ｂに係合可能な***部６５ａを形成してなる。このように形成される化粧材６５は、例えばアルミニウム合金製押出形材あるいは合成樹脂製部材時等にて形成される。   The decorative material 65 is formed in a substantially U-shaped cross section having an opening on the groove 63 side, and accommodates the head of the fixing screw 18 in the opening in a state where the opening of the groove 63 is hidden. At the same time, a ridge 65a that can be engaged with an engaging protrusion 63b provided at the opening end of the groove 63 is formed at the base end of the pair of side pieces. The decorative material 65 formed in this way is formed by, for example, an aluminum alloy extruded shape member or a synthetic resin member.

このように目地材６の凹溝６３に化粧材６５を嵌入することで、凹溝６３を目隠しすることができるので、目地部の美観の向上を図ることができる。   By fitting the decorative material 65 into the concave groove 63 of the joint material 6 in this way, the concave groove 63 can be concealed, so that the appearance of the joint portion can be improved.

一方、目地片６４は、パネル体１０に対して水平に形成されており、先端部の室内側にシール部材５１を着脱可能に装着するチャンネル状の収容溝６４ａが形成されている。   On the other hand, the joint piece 64 is formed horizontally with respect to the panel body 10, and a channel-shaped accommodation groove 64 a on which the seal member 51 is detachably mounted is formed on the indoor side of the tip portion.

上記シール部材５１は、外壁パネル材１のパネル体１０に弾性を有して当接する断面略く字状のシール部と、弾性変形可能な中空状の嵌合部とで形成されている。   The seal member 51 is formed by a substantially cross-sectionally-shaped seal portion that elastically contacts the panel body 10 of the outer wall panel member 1 and a hollow fitting portion that can be elastically deformed.

このように形成されるシール部材５１によって、外壁パネル材１の目地部に目地材６を取り付けた際、目地材６とパネル体１０とを気水密にすることができる。   When the joint material 6 is attached to the joint portion of the outer wall panel material 1 by the seal member 51 formed in this way, the joint material 6 and the panel body 10 can be air-tight.

上記突出部６１は、目板部６０の凹溝６３の一方の側部（図４ないし図８において左側）から室内側に向かって延在されている。   The protruding portion 61 extends from one side (left side in FIGS. 4 to 8) of the concave groove 63 of the eyeplate portion 60 toward the indoor side.

上記折曲部６２は、突出部６１の先端から図４ないし図８において右側に略直角に折曲されており、室内側面に例えば接着剤等の接着手段によりパッキン５０が取り付けられている。   The bent portion 62 is bent at a substantially right angle from the tip of the protruding portion 61 to the right side in FIGS. 4 to 8, and the packing 50 is attached to the indoor side surface by an adhesive means such as an adhesive.

上記パッキン５０は、耐候性，耐熱性等に富む弾性を有する材料、例えばエチレン・プロピレン共重合体（ＥＰＤＭ）によって形成されている。このパッキン５０は、上記両水密保持片３２に当接されると共に、両水密保持材３０間に形成される隙間Ｓを塞ぐように弾性変形することによって、目地材６と水密保持材３０とを密接することができるので、目地部の気水密性の向上を図ることができる。   The packing 50 is made of an elastic material rich in weather resistance, heat resistance, etc., for example, an ethylene / propylene copolymer (EPDM). The packing 50 is brought into contact with the two watertight holding pieces 32 and elastically deforms so as to close the gap S formed between the two watertight holding members 30, thereby connecting the joint material 6 and the watertight holding member 30. Since close contact can be achieved, the airtightness of the joint can be improved.

上記のように形成された目地材６によって外壁パネル材１の目地部を閉塞するには、以下の手順によって行う。まず、目地材６の両収容溝６４ａにシール部材５１を嵌装した状態で、図７及び図８に示すように、右側に位置する目地片６４の端部を外壁パネル材１のパネル体１０に当接させると共に、反対側すなわち左側に位置する目地片６４を外壁パネル材１から離れた位置に配置する。この状態において目地材６の折曲部６２が目地支持材４０の目地支持片４２と干渉しないように、右側の目地片６４の端部を中心にして目地材６を時計回りに回転させると共に、折曲部６２を目地支持片４２の室内側空間に移動させる。   To close the joint portion of the outer wall panel material 1 with the joint material 6 formed as described above, the following procedure is performed. First, in a state where the seal member 51 is fitted in both the receiving grooves 64a of the joint material 6, as shown in FIGS. 7 and 8, the end of the joint piece 64 located on the right side is the panel body 10 of the outer wall panel material 1. The joint piece 64 located on the opposite side, that is, on the left side is disposed at a position away from the outer wall panel material 1. In this state, the joint material 6 is rotated clockwise around the end of the right joint piece 64 so that the bent portion 62 of the joint material 6 does not interfere with the joint support piece 42 of the joint support member 40, and The bent part 62 is moved to the indoor space of the joint support piece 42.

次に、外壁パネル材１間の目地部を目地材６の目板部６０によって閉塞するように、目地材６の取り付け位置を決め、この状態で、目地材６の凹溝６３内に適宜間隔をおいて電動ドリル等によって凹溝６３の底部６３ａと目地支持材４０の目地支持片４２とを貫通する取付孔（図示せず）を穿設する。そして、この取付孔に固定ねじ１８を螺合することによって目地材６と目地支持材４０が固定されると共に、目地材６の折曲部６２に取り付けられたパッキン５０が両水密保持材３０に当接し、更に固定ねじ１８をねじ込むことによって、両水密保持材３０間に形成される隙間Ｓを塞ぐようにパッキン５０が弾性変形して、隙間Ｓを密閉することができる。また、両目地片６４の先端部に装着されたシール部材５１は、固定ねじ１８をねじ込むことによって、パネル体１０に当接すると共に、弾性変形するので、目地材６とパネル体１０の気水密性の向上を図ることができる。このように目地材６を外壁パネル材１の目地部に固定ねじ１８によって取り付けた後に、目地材６の凹溝６３に化粧材６５を嵌入することで、外壁パネル材１の目地部への目地材６の取付作業を終了する。   Next, the attachment position of the joint material 6 is determined so that the joint portion between the outer wall panel materials 1 is closed by the joint plate portion 60 of the joint material 6, and in this state, an appropriate interval is provided in the concave groove 63 of the joint material 6. A mounting hole (not shown) that penetrates the bottom 63a of the concave groove 63 and the joint support piece 42 of the joint support member 40 is formed by an electric drill or the like. The joint material 6 and the joint support member 40 are fixed by screwing the fixing screw 18 into the attachment hole, and the packing 50 attached to the bent portion 62 of the joint member 6 is attached to the both watertight holding members 30. By abutting and further screwing the fixing screw 18, the packing 50 is elastically deformed so as to close the gap S formed between the two watertight holding members 30, and the gap S can be sealed. In addition, the seal member 51 mounted on the tip portions of the joint pieces 64 is in contact with the panel body 10 and is elastically deformed by screwing the fixing screw 18, so that the air-tightness of the joint material 6 and the panel body 10 is improved. Can be improved. Thus, after attaching the joint material 6 to the joint portion of the outer wall panel material 1 with the fixing screw 18, the decorative material 65 is inserted into the concave groove 63 of the joint material 6, thereby joining the joint portion to the joint portion of the outer wall panel material 1. The work of attaching the material 6 is finished.

また、建物Ｂを解体する際に、外壁パネル材１の目地部から目地材６を取り外すには、上記説明と逆の手順を行えばよく、まず、目地材６の凹溝６３から化粧材６５を取り外し、凹溝６３内の固定ねじ１８を緩めることによって、目地材６と水密保持材３０との固定が解かれる。次に、目地部から目地材６を引き離すと共に、目地材６の折曲部６２が目地支持材４０の目地支持片４２と干渉しないように、右側に位置する目地片６４の端部をパネル体１０に当接させる。そして、この右側の目地片６４の端部を中心に目地材６を反時計回りに回転することによって、折曲部６２を目地支持片４２より室外側に移動させて目地材６を外壁パネル材１の目地部から取り外すことで、目地材６の取り外し作業を終了する。   In order to remove the joint material 6 from the joint portion of the outer wall panel material 1 when the building B is dismantled, the reverse procedure to the above description may be performed. First, the decorative material 65 from the concave groove 63 of the joint material 6 is used. Is removed and the fixing screw 18 in the concave groove 63 is loosened, so that the joint material 6 and the watertight holding member 30 are fixed. Next, while pulling the joint material 6 away from the joint portion, the end portion of the joint piece 64 positioned on the right side is arranged so that the bent portion 62 of the joint material 6 does not interfere with the joint support piece 42 of the joint support member 40. 10 is contacted. Then, by rotating the joint material 6 counterclockwise around the end of the right joint piece 64, the bent portion 62 is moved to the outdoor side from the joint support piece 42, and the joint material 6 is moved to the outer wall panel material. The removal work of the joint material 6 is completed by removing it from the joint part 1.
