Description

本発明は、例えば窯業系の外壁板を構造躯体に留め付けるときに用いる留め付け金具、およびその留め付け金具を用いた外壁施工構造に関する。   The present invention relates to, for example, a fastener used when fastening a ceramic-type outer wall plate to a structural frame, and an outer wall construction structure using the fastener.

建物の外壁施工として、図５に示すような少なくとも上端縁と下端縁に実部４４，４２を有する外壁板４０を、留め付け金具を用いて躯体側に留め付け施工することが行われる（例えば、特許文献１：特開２００１−２７０３１号公報参照）。図６は特許文献１に記載される留め付け金具を示している。この留め付け金具５０は、一枚の鋼板を折り曲げ加工して形成されており、留め付け時に上下の建築板の裏面に当接される支持部５１ａ，５１ｂと、支持部５１の中央部分を連続的に折り曲げて形成される係止部５２と、支持部５１ａの上方の基板部５３と、支持部５１ｂ下端の屈曲部５４とからなる。躯体側へ留め付け金具５０を固定するときには、基板部５３と屈曲部５４の先端とが躯体側への固定部となる。   As an outer wall construction of a building, an outer wall plate 40 having actual parts 44 and 42 at least at an upper edge and a lower edge as shown in FIG. Patent Document 1: Japanese Patent Laid-Open No. 2001-27031). FIG. 6 shows a fastening bracket described in Patent Document 1. The fastening bracket 50 is formed by bending a single steel plate, and the support portions 51a and 51b that are in contact with the back surfaces of the upper and lower building boards during fastening and the central portion of the support portion 51 are continuously connected. The locking portion 52 is formed by being bent, a substrate portion 53 above the support portion 51a, and a bent portion 54 at the lower end of the support portion 51b. When the fastening metal fitting 50 is fixed to the housing side, the substrate portion 53 and the tip of the bent portion 54 become fixing portions to the housing side.

施工時には、上位の外壁板が、その下端縁の実部４２を係止部５２に係止し、かつ裏面を支持部５１ａに当接した状態で留め付けられ、下位の外壁板が、その上端縁の実部４４を係止部５２に係止し、かつ裏面を支持部５１ｂに当接した状態で留め付けられる。また、この留め付け金具５０では、支持部５１ａに躯体側に達する凹孔６１が形成されており、留め付け金具５０の躯体への取り付け状態を安定化している。外壁板を留め付けた状態では、外壁板裏面と構造躯体との間に、基板部５３の面と支持部５１の面との間隔分の空間が形成されるので、通気が確保される。   At the time of construction, the upper outer wall plate is fastened with the lower end edge of the real part 42 locked to the locking portion 52 and the back surface in contact with the support portion 51a. The edge real part 44 is locked to the locking part 52, and the back surface is fastened in contact with the support part 51b. Moreover, in this fastening metal fitting 50, a concave hole 61 reaching the housing side is formed in the support portion 51a, and the attachment state of the fastening metal fitting 50 to the housing is stabilized. In the state where the outer wall plate is fastened, a space corresponding to the space between the surface of the substrate portion 53 and the surface of the support portion 51 is formed between the rear surface of the outer wall plate and the structural housing, so that ventilation is ensured.

特許文献２（特開平９−３０２８８９号公報）には、図７に示すように、やはり、一枚の鋼板を折り曲げ加工して形成される留め付け金具７０が示される。この留め付け金具７０は、躯体側への固定部である基板部７１と、基板部７１の左右側端部に基板部より前方に突き出た状態で上下方向に形成される支持部７２，７２と、左右の支持部７２，７２の間に左右方向に形成され先端が前記支持部７２，７２よりも前方に位置する係止部７３とを備える。係止部７３は、基板部７１の下方領域を折り曲げて形成されており、その先端の両側部を上方に折り返した立ち上がり部７５，７５と、該先端の中央部を下方に折り曲げて形成した立ち下がり部７６とを備える。上位の外壁板は、その下端縁の実部４２を係止部７３に係止し、かつ裏面を支持部７２，７２に当接した状態で留め付けられ、下位の外壁板は、その上端縁の実部４４を係止部７３に係止し、かつ裏面を同様に支持部７２，７２に当接した状態で留め付けられる。外壁板を留め付けた状態では、外壁板裏面と構造躯体との間には支持部７２の高さ分の空間が形成されるので、通気が確保される。   Patent Document 2 (Japanese Patent Laid-Open No. 9-302889) shows a fastener 70 formed by bending a single steel plate as shown in FIG. The fastening bracket 70 includes a base plate portion 71 that is a fixing portion to the housing side, and support portions 72 and 72 that are formed in the vertical direction in a state of protruding forward from the base plate portion at the left and right side end portions of the base plate portion 71. And a locking portion 73 formed between the left and right support portions 72, 72 in the left-right direction and having a tip positioned forward of the support portions 72, 72. The locking portion 73 is formed by bending the lower region of the substrate portion 71. The rising portions 75 and 75 are formed by folding both side portions of the tip upward and the center portion of the tip is folded downward. And a descending portion 76. The upper outer wall plate is fastened with the real part 42 at the lower edge thereof locked to the locking portion 73 and the back surface is in contact with the support portions 72, 72. The real part 44 is locked to the locking part 73, and the back surface is similarly fastened in contact with the support parts 72, 72.

図６に示される留め付け金具５０は、鋼板を二重に積層して係止部５２を形成しているため、やや重くかつ使用鋼板量も大きくなって高コストとなっていた。   The fastening metal fitting 50 shown in FIG. 6 has a steel plate double stacked to form the locking portion 52, so that it is somewhat heavy and the amount of used steel plate is large, resulting in high cost.

図７に示す留め付け金具７０では、係止部７３は一枚板構成であり、軽量化と低コスト化が図られる。しかし、係止部７３が、躯体側への固定部である基板部７１から延出する構成とされているため、図６に示した留め付け金具５０のように係止部５２が支持部５１から延出する構成とされているものと比べると、留め付け金具７０では係止部７３の長さが長くなっているため、特に重量のある大型の外壁板を留め付けるような場合には、係止部７３の強度にやや問題があった。   In the fastening metal fitting 70 shown in FIG. 7, the locking portion 73 has a single plate configuration, and weight reduction and cost reduction are achieved. However, since the locking portion 73 is configured to extend from the substrate portion 71 that is a fixing portion to the housing side, the locking portion 52 is the support portion 51 like the fastening metal fitting 50 shown in FIG. Since the length of the locking portion 73 is longer in the fastening metal fitting 70 than the one configured to extend from the case, particularly in the case of fastening a large-sized outer wall plate having a heavy weight, There was a slight problem with the strength of the locking portion 73.

また、留め付け金具７０では、左右の支持部７２，７２のみで外壁板の裏面を支持する構成とされているため、特に左右に隣接する２枚の外壁板の隣接部分を１つの留め付け金具７０で留め付けるような場合には、左右いずれか１つの支持部７２のみで各外壁板の裏面を支持することとなり、留め付け状態の安定性にやや問題があった。   Further, since the fastening bracket 70 is configured to support the back surface of the outer wall plate only by the left and right support portions 72, 72, the adjacent portion of the two outer wall plates adjacent to the left and right in particular is one fastening bracket. In the case of fastening with 70, the rear surface of each outer wall plate is supported by only one of the left and right support portions 72, and there is a slight problem in the stability of the fastening state.

本発明は、上記のような事情に鑑みてなされたものであり、一枚の鋼板から形成される留め付け金具において、少ない鋼板量で製造が可能であり、軽量化と低コスト化が図られると共に、係止部が十分な強度を有し、外壁板を安定して支持することのできる、改良された留め付け金具を提供することを目的とする。また、本発明の他の目的は、前記の留め付け金具を用いた安定性の高い外壁板施工構造を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and can be manufactured with a small amount of steel sheet in a fastening member formed from a single steel sheet, thereby achieving weight reduction and cost reduction. In addition, an object of the present invention is to provide an improved fastening member in which the locking portion has sufficient strength and can stably support the outer wall plate. Another object of the present invention is to provide a highly stable outer wall plate construction structure using the above-described fastener.

本発明による留め付け金具は、外壁板用の留め付け金具であって、その左右の側部には、留め付け時に外壁板裏面に当接される左側支持部および右側支持部が設けられており、該左側および右側支持部に挟まれた中間領域には、上方から下方にかけて、躯体側への固定部となる基板部と、留め付け時に外壁板裏面に当接される中央支持部と、該中央支持部の下端から延出し、留め付け時に外壁板の上下端に係止される係止部と、留め付け時に外壁板裏面に当接される下側支持部と、が設けられており、該留め付け金具は１枚の鋼板から形成されていて、鋼板の上方領域の一部を裏面側に陥没させられた状態とすることにより前記基板部が形成されており、また、鋼板の下方領域の一部を表面側に切り起こされた状態とすることにより前記係止部が形成されていることを特徴とする。   The fastening bracket according to the present invention is a fastening bracket for an outer wall plate, and a left side support portion and a right side support portion that are brought into contact with the back surface of the outer wall plate at the time of fastening are provided on the left and right sides thereof. The intermediate region sandwiched between the left and right support portions, from above to below, is a base plate portion to be fixed to the housing side, a central support portion that comes into contact with the back surface of the outer wall plate when fastened, A locking portion that extends from the lower end of the central support portion and is locked to the upper and lower ends of the outer wall plate when fastened, and a lower support portion that comes into contact with the back surface of the outer wall plate when fastened, The fastening bracket is formed of a single steel plate, and the substrate portion is formed by setting a part of the upper region of the steel plate to be depressed on the back surface side, and the lower region of the steel plate. The locking is achieved by cutting and raising a part of the surface to the surface side. Wherein the but has been formed.

上記の留め付け金具では、係止部が、金具の材料となる鋼板の一部を切り欠き、それを利用して構成されるので、すべて一枚板構成とすることができ、図６に示した従来の留め付け金具５０に比べて軽量化と低コスト化が図られる。そして、係止部が支持部から延出する構成とされているので、図７に示した従来の留め付け金具７０のように係止部７３が基板部７１から延出している場合に比べ、係止部の長さは短くてすみ、そのため、係止部が一枚板で構成されているにも関わらず十分な強度を発揮することができる。   In the above fastening bracket, the locking portion is formed by cutting out a part of the steel plate used as the material of the bracket, and is configured by using it. Compared with the conventional fastening metal fitting 50, the weight and cost can be reduced. And since it is set as the structure which a latching | locking part extends from a support part, compared with the case where the latching | locking part 73 is extended from the board | substrate part 71 like the conventional fastening metal fitting 70 shown in FIG. The length of the locking portion may be short, and therefore sufficient strength can be exhibited even though the locking portion is constituted by a single plate.

さらに、留め付け金具の左右の側部と、係止部の上下とに設けられた各支持部によって外壁板の裏面を支持するようにしているので、図７に示した従来の留め付け金具７０のように左右２つの支持部のみで外壁板裏面を支持する場合に比べて、外壁板裏面をより確実に支持することができる。特に、２枚の外壁板が左右に隣接する部分において、両方の外壁板の下端を１つの留め付け金具で固定するような場合であっても、それぞれの外壁板を、左右いずれかの支持部と中央支持部との二箇所で支持することができるので、安定した状態で外壁板を留め付けることができる。   Furthermore, since the back surface of the outer wall plate is supported by the support portions provided on the left and right side portions of the fastener and the upper and lower portions of the locking portion, the conventional fastener 70 shown in FIG. Thus, the outer wall plate back surface can be more reliably supported as compared with the case where the outer wall plate back surface is supported by only the two left and right support portions. In particular, in a portion where two outer wall plates are adjacent to each other on the left and right, even if the lower ends of both outer wall plates are fixed with one fastening bracket, each outer wall plate is attached to either the left or right support portion. Since it can support in two places with a center support part, an outer wall board can be fastened in the stable state.

好ましくは、前記係止部は、その先端部に、少なくとも１つの立ち上がり部と少なくとも１つの立ち下がり部とを備える。この態様では、係止部を簡単な折り曲げ加工によって形成することができ、かつ外壁板の上下端を確実に係止することができる。   Preferably, the locking portion includes at least one rising portion and at least one falling portion at a tip portion thereof. In this aspect, the locking portion can be formed by a simple bending process, and the upper and lower ends of the outer wall plate can be reliably locked.

好ましくは、前記係止部の立ち下がり部の左右両側の下端近傍が留め付け金具の裏面側へ折曲しており、該折曲部は留め付け時に外壁板に圧接するようになっている。この態様では、外壁板を支持部に向けて押圧した姿勢に維持できるので留め付け状態が安定する。さらに、折曲部の先端が外壁板表面に食い込むような形状とすることにより、楔効果による固定安定性も確保できる。   Preferably, the vicinity of the lower ends of the right and left sides of the falling portion of the locking portion is bent toward the back side of the fastening bracket, and the bent portion is pressed against the outer wall plate when fastened. In this aspect, since the outer wall plate can be maintained in a posture pressed toward the support portion, the fastening state is stabilized. Furthermore, fixing stability due to the wedge effect can be ensured by adopting a shape in which the tip of the bent portion bites into the surface of the outer wall plate.

好ましくは、前記左側、右側および下側支持部のうち少なくとも１つの支持部は、その外側縁部からさらに外側に延出する鍔部を備えており、該鍔部は前記基板部と同一平面上に位置する。この態様では、基板部に加えて鍔部も躯体側に当接されることにより、留め付け金具の躯体側への固定はより安定したものになる。   Preferably, at least one of the left side, the right side, and the lower side support portion includes a flange portion that extends further outward from an outer edge portion thereof, and the flange portion is flush with the substrate portion. Located in. In this aspect, since the collar portion is also brought into contact with the housing side in addition to the substrate portion, the fixing of the fastener to the housing side becomes more stable.

好ましくは、前記基板部の上側縁には、前記左側および右側支持部の付近に切り込みが設けられている。この態様では、留め付けた外壁板に大きな風圧（負圧）が作用した場合でも、基板部の上記切り込み付近が一時的に変形して風圧（負圧）を吸収することにより、係止部に係止された外壁板の実部に荷重がかかるのを緩和することができる。それにより、安定性の高い留め付け態様を長期にわたり保持することができる。   Preferably, the upper edge of the substrate portion is provided with cuts in the vicinity of the left and right support portions. In this aspect, even when a large wind pressure (negative pressure) acts on the clamped outer wall plate, the vicinity of the notch in the substrate portion is temporarily deformed to absorb the wind pressure (negative pressure), thereby It is possible to reduce the load applied to the real part of the locked outer wall plate. Thereby, a highly stable fastening mode can be maintained over a long period of time.

本発明は、また、上記の留め付け金具を用いた外壁施工構造として、留め付け金具が前記基板部を躯体側の固定面に当接して多段に取り付けてあり、少なくとも上端縁と下端縁に実部を有する外壁板が、その裏面を留め付け金具の前記左側、右側、中央、下側の各支持部に当接し、上端縁の実部を上位に位置する留め付け金具の前記係止部に係止し、下端縁の実部を下位に位置する留め付け金具の前記係止部に係止した状態で、多段に留め付けられていることを特徴とする外壁施工構造をも開示する。   According to the present invention, as the outer wall construction structure using the above-described fastening bracket, the fastening bracket is attached in multiple stages by contacting the base plate portion with the fixing surface on the housing side, and at least at the upper edge and the lower edge. The outer wall plate having a portion abuts the back surface of each of the left side, right side, center, and lower side support portions of the fastener, and the real portion of the upper end edge is positioned on the latch portion of the fastener. Also disclosed is an outer wall construction structure that is locked and multi-staged with the real part of the lower end edge being locked to the locking part of the fastening metal fitting positioned below.

上記の外壁施工構造では、留め付け金具の軽量化と低コスト化が図られているので、施工コストを低減すると共に、確実な留め付け状態を得ることができる。また、留め付けた外壁板の裏面には通気用の空間が形成されているため、結露などの不都合が生じるのを回避できる。   In the outer wall construction structure described above, the weight and cost of the fastener are reduced, so that the construction cost can be reduced and a reliable fastening state can be obtained. Further, since a ventilation space is formed on the back surface of the fastened outer wall plate, it is possible to avoid the occurrence of inconvenience such as condensation.

上記のように本発明による留め付け金具は、全体が一枚板で構成されているため軽量であり低コスト品でありながら、係止部および支持部により外壁板を確実に支持することができる。そのために、本発明による外壁施工構造では、外壁板の留め付け状態を長期にわたり安定した状態に保持することができる。   As described above, since the fastening metal fitting according to the present invention is composed of a single plate as a whole, the fastening plate and the support portion can reliably support the outer wall plate while being lightweight and low-cost. . Therefore, in the outer wall construction structure according to the present invention, the fastening state of the outer wall plate can be maintained in a stable state over a long period of time.

以下、図面を参照しながら、本発明による留め付け金具とそれを用いた外壁施工構造の一実施の形態を説明する。図１は本発明による留め付け金具の一実施の形態を示す斜視図であり、図３はそれを用いた外壁施工構造を示す斜視図である。   Hereinafter, an embodiment of a fastening metal fitting according to the present invention and an outer wall construction structure using the same will be described with reference to the drawings.

Further, in the middle region sandwiched between the left and right support portions 12L and 12R, from above to below, the substrate portion 11 that is a fixing portion to the housing side, and the central support that comes into contact with the rear surface of the outer wall plate when fastened A portion 12C, a locking portion 21 locked to the upper and lower ends of the outer wall plate at the time of fastening, and a lower support portion 12U to be brought into contact with the back surface of the outer wall plate at the time of fastening are provided.

留め付け金具１０は、例えばステンレス鋼板や合金メッキ鋼板などの一枚の鋼板からの打ち抜きと、絞り、折り曲げ加工により形成される。図２は留め付け金具１０の材料となる鋼板を示している。この鋼板１００は厚さが１．０ｍｍ程度とされており、このようにやや厚みのある鋼板を使用することにより、留め付け金具１０に設ける補強リブが少数ですむようにしている。なお、鋼板１００の各部分が完成後の留め付け金具１０のどの部分に対応するかを示すため、図１における留め付け金具１０の各部の符号を、図２においてもカッコ付きで示している。   The fastener 10 is formed by punching from a single steel plate such as a stainless steel plate or an alloy plated steel plate, drawing, and bending. FIG. 2 shows a steel plate as a material for the fastener 10. The steel plate 100 has a thickness of about 1.0 mm. By using a steel plate having a slight thickness as described above, a small number of reinforcing ribs are provided on the fastener 10. In addition, in order to show which part of the fastener 10 after completion | finish to which each part of the steel plate 100 respond | corresponds, the code | symbol of each part of the fastener 10 in FIG. 1 is shown with the parenthesis also in FIG.

However, the fastening bracket of the present invention is not limited to this embodiment, and for example, the flange portion 13 and the notch 36 can be omitted.

次に、上記留め付け金具１０を用いた外壁施工構造について説明する。留め付け金具１０を用いて、図５に示したような外壁板４０を留め付けた状態が図３に示される。図４は、図３のＩＶ−ＩＶ線による断面図である。留め付け金具１０は、この例では基板部１１に形成した釘孔３４を利用して、構造躯体１に防水紙Ｐおよび胴縁２を介して釘３によって固定される。その際に、下位に位置する下外壁板４０Ａの上端縁の実部４４に、留め付け金具１０の係止部２１が外嵌合するようにして位置決めをし、その状態で釘孔３４を利用して固定する。釘孔３４は膨出部３２の上斜面３３に形成されており、釘打ち時に下方に向けて留め付け金具１０全体が押し下げられるので、固定状態は安定する。また、立ち下がり部２３の左右両側に形成した折曲部２３ａ，２３ａにより外壁板４０Ａは構造躯体１側に押し付けられるので、外壁板裏面は支持部１２Ｌ，１２Ｒ，１２Ｕに密着した状態となり、楔作用によって外壁板の左右移動が防止されるため、留め付け状態は一層安定する。なお、下外壁板４０Ａの上端縁の実部４４の根元付近には漏水防止のためコーキング材４が予め打設されている。   Next, the outer wall construction structure using the above-described fastener 10 will be described. FIG. 3 shows a state in which the outer wall plate 40 as shown in FIG. 5 is fastened using the fastener 10. 4 is a cross-sectional view taken along line IV-IV in FIG. In this example, the fastener 10 is fixed to the structural housing 1 by the nail 3 via the waterproof paper P and the trunk edge 2 using a nail hole 34 formed in the substrate portion 11. At that time, positioning is performed so that the locking portion 21 of the fastening bracket 10 is fitted to the real portion 44 of the upper end edge of the lower outer wall plate 40A located at the lower position, and the nail hole 34 is used in that state. And fix. The nail hole 34 is formed in the upper slope 33 of the bulging portion 32, and the entire fastening bracket 10 is pushed downward when nailing, so that the fixed state is stable. Further, since the outer wall plate 40A is pressed against the structural housing 1 by the bent portions 23a and 23a formed on the left and right sides of the falling portion 23, the rear surface of the outer wall plate is in close contact with the support portions 12L, 12R, and 12U, and the wedge Since the action prevents the outer wall plate from moving left and right, the fastening state is further stabilized. A caulking material 4 is previously placed in the vicinity of the base of the real part 44 at the upper end edge of the lower outer wall plate 40A to prevent water leakage.

所要個数の留め付け金具１０を同様にして水平方向に所定間隔で固定した後、上位に位置する上外壁板４０Ｂを、その下端縁の実部４２が留め付け金具１０の係止部２２の部分に内嵌合するようにして、必要枚数横方向に配置する。このようにして配置した上外壁板４０Ｂを下外壁板として、さらに、その上端縁の実部４４に前記と同様にして留め付け金具１０を取り付けた後、打ち付け固定する。以下、必要な段数だけ同じ工程を繰り返すことにより、本発明による外壁施工構造は完成する。   After fixing the required number of fasteners 10 in the same manner in the horizontal direction at a predetermined interval, the upper outer wall plate 40B positioned at the upper position is a part of the engaging portion 22 of the fastener 10 whose real part 42 at the lower edge is The required number is arranged in the lateral direction so as to fit inside. The upper outer wall plate 40B arranged in this way is used as the lower outer wall plate, and the fastener 10 is attached to the real part 44 at the upper end edge in the same manner as described above, and then fixed. Hereinafter, the outer wall construction structure according to the present invention is completed by repeating the same steps as many times as necessary.
