Description

本発明は、主として嵌合ハゼを採用している屋根に使用する他部材取付金具に関するものである。   The present invention relates to another member mounting bracket mainly used for a roof that employs a fitting gob.

薄金属板葺きの屋根は、金属板の連結部分がハゼ構造（重合折曲）となっており、当該屋根上に雪止め構造や、その他種々の構造物を設ける場合に、当該ハゼ構造に部材固定の根拠を求めているものである。   Thin metal plate roofing has a goby structure (overlapping folding) at the metal plate connection part, and when a snow stop structure or other various structures are provided on the roof, members are fixed to the goby structure. This is what we are looking for.

特にハゼ構造が立ち上がり形状に形成されている屋根においては、下方開口コの字状部材や２枚の部材を採用し、対向板部に貫通緊締ボルトと緊締ナットを付設し、両者の螺合緊締によって所定個所（ハゼ構造個所）を挟圧して固定する金具本体を用い、当該金具本体に、雪止めアングルや雪止め板を装着して屋根の雪滑り止めを実現したり、その他の構造物を装着して屋根上に設置しているものである。   In particular, in roofs where the goby structure is formed in a rising shape, a U-shaped member with a downward opening or two members is used, and through-tightening bolts and tightening nuts are attached to the opposing plate, and both are tightened with screws. Using a metal fitting body that clamps and fixes a predetermined location (a goby structure location) by attaching a snow stop angle or snow stop plate to the metal fitting body to achieve snow slip prevention on the roof, or other structures It is installed and installed on the roof.

本発明は、特にハゼ構造部分が中空構造となっている所謂嵌合ハゼ（折版屋根の嵌合式ハゼ、嵌合立平）を採用している屋根を対象とするものである。従前の公知の嵌合ハゼ方式の屋根に装着する金具は、貫通緊締ボルトと緊締ナットの緊締螺合によって、ハゼ部全体を挟圧抱持する挟持部を備えた器具（特許文献１）、対向板部の下縁を内方に折曲して、ハゼ嵌合個所下方の重合部分を挟圧する爪縁を備えた器具（特許文献２）等が知られている。   The present invention is particularly directed to a roof that employs a so-called mating goby (a mated goby of a folded plate roof, a mating upright) having a hollow structure portion. A metal fitting to be mounted on a conventional well-fitted roof-type roof is an instrument having a clamping part that holds and holds the entire goby part by fastening screwing of a through-tightening bolt and a fastening nut (Patent Document 1), A device (Patent Document 2) having a claw edge that bends the lower edge of the plate portion inward and clamps the overlapped portion below the goby fitting portion is known.

特開平１１−１２４９６９号公報。Japanese Patent Application Laid-Open No. 11-124969. 登録実用新案第３１４８１３０号公報。Registered Utility Model No. 3148130.

嵌合ハゼ部分を挟圧抱持する器具においては、抱持圧力が充分でなければ滑り落ち易いので、嵌合ハゼ部が変形する程度の強い抱持圧力を加える必要があり、屋根装着作業が必ずしも効率的に行えるとは云い難い。   In instruments that hold the mated goby part under pressure, it is easy to slide down if the holding pressure is not sufficient, so it is necessary to apply a strong holding pressure to the extent that the mated goby part is deformed, It is not necessarily efficient.

また嵌合ハゼ部の下方重合部分を挟圧する器具は、例えば嵌合立平と称されている嵌合ハゼ部は、下方重合部分は内方に空間を有する構造であり、当該個所を金具の爪縁で挟圧すると容易に変形してしまい、屋根材を傷めてしまう。更に嵌合ハゼにおける外側板の端縁と内側板面との間は、本来なら前記の端縁が跳ね上がって広い間隙となっているのに、挟圧変形によって狭くなり、当該個所の毛細管現象で雨水を吸い上げ、屋根下地材を傷める原因となる。   In addition, an instrument that clamps the lower overlapping portion of the fitting goby portion is, for example, a fitting goby portion called a fitting standing flat, and the lower overlapping portion has a structure having an inner space, and the portion is attached to the bracket. If it is pinched with a claw edge, it will be easily deformed and the roofing material will be damaged. Furthermore, the gap between the edge of the outer plate and the inner plate surface of the fitting gouge is normally narrowed by pinching deformation, although the above edge jumps up and becomes a wide gap. It can cause rainwater to be sucked up and damage the roof substrate.

そこで本発明は、嵌合ハゼ部の上方の中空部分を挟圧する新規な屋根用他部材取付金具を提案したものである。   Therefore, the present invention proposes a new roof other member mounting bracket that clamps the hollow portion above the fitting gob.

本発明に係る屋根用他部材取付金具は、 対向板部に貫通した緊締ボルトに緊締ナットを螺合装着して、対向板部で装着対象の屋根ハゼ部を挟圧して屋根上に固着する屋根用他部材取付金具において、対向板部から内方に折曲した折曲板部を設けると共に、前記折曲板部の端縁に、使用対象屋根の嵌合ハゼ部における棒出中空部分に当接して、対向板部の近接で嵌合ハゼ部を挟圧する挟持突起部と、緊締ボルトの貫通位置より下方において、対向板部の近接間隔を一定以上に制限する衝突ストッパー部とを備えてなることを特徴とするものである。 The other member mounting bracket for roof according to the present invention is a roof in which a tightening nut is screwed and attached to a tightening bolt penetrating the opposing plate portion, and the roof gouge portion to be attached is sandwiched between the opposing plate portions and fixed on the roof. The other member mounting bracket is provided with a bent plate portion bent inward from the opposing plate portion, and at the end edge of the bent plate portion, it is in contact with the sticking hollow portion of the fitting gouge portion of the roof to be used. In contact therewith, a clamping projection that clamps the fitting gob in the proximity of the opposing plate and a collision stopper that limits the proximity of the opposing plate below a certain level below the tightening bolt penetration position. It is characterized by this.

而して前記金具を屋根上の嵌合ハゼ部に跨がせ、緊締ボルトに螺合した緊締ナットを締め付けて対向板部を近接させると、挟持突起部が嵌合ハゼ部の中空個所（嵌合ハゼ上方部分）に食い込んで当該個所を凹ませ、所定の食い込み状態となると（対向板部が一定以上近接すると）、衝突ストッパー部が当接状態となり、対向板部のそれ以上の接近を阻止し、挟持突起部の食い込みも当該状態で停止する。   Thus, when the metal fitting is straddled over the fitting gouge portion on the roof and the fastening nut screwed to the fastening bolt is tightened to bring the opposing plate portion close to each other, the sandwiching projection portion becomes a hollow portion (fitting) of the fitting gouge portion. The upper part of the joint gob) is recessed and the corresponding part is recessed, and when the predetermined bite state is reached (when the opposing plate part is close to a certain distance), the collision stopper part comes into contact and prevents further approach of the opposing plate part. However, the biting of the sandwiching protrusions also stops in this state.

従って前記金具は、作業者が緊締ボルト・ナットの螺合作業を行った場合に、締め付け過ぎが生ずることなく、所定の固着力（ずり落ち抵抗）を保持して、器具が嵌合ハゼに装着されるものである。   Therefore, when the operator performs the tightening bolt / nut screwing operation, the fitting is not over-tightened and maintains a predetermined fixing force (slipping resistance), and the tool is mounted on the fitting gouge. It is what is done.

また本発明（請求項２）は、前記の屋根用他部材取付金具において、対向板部が、下方開口コの字状の本体の両側部分で構成してなり、対向板部の前後縁を内方に折曲して折曲板部を形成すると共に、対向板部の下縁部分を内外に折曲して安定板部としてなるもので、挟持突起部及び衝突ストッパー部を容易に形成することができるものである。 Further, according to the present invention (invention 2), in the other member mounting bracket for roof, the opposing plate portion is constituted by both side portions of the U-shaped main body of the lower opening, and the front and rear edges of the opposing plate portion are arranged inside. co If by bending towards forming the bent plate portion, by bending the lower edge portion of the pair towards the plate portion to the inner and outer made of a stabilizer unit, easily formed clamping projections and collision stopper portion Is something that can be done.

本発明は上記の構成のとおりで、嵌合ハゼ葺きの屋根において、挟持突起を嵌合中空部分に食い込ませることで器具を固着するので、当該食い込みによって充分な固着力（ずり落ち抵抗）を備え、ハゼ部分を大きく変形したり、傷付けることなく器具の固着を実現すると共に、衝突ストッパー部を備えることで、前記の食い込み程度を一定に制限し、緊締ボルト・ナットの締め付け過ぎを防止して、施工時の作業能率が高められるものである。   The present invention has the above-described configuration, and in the fitting roof, the instrument is fixed by biting the holding protrusion into the fitting hollow portion, and therefore, sufficient biting force (sliding resistance) is provided by the biting. In addition to realizing the fixing of the instrument without greatly deforming or damaging the goby part, by providing a collision stopper part, the above biting degree is limited to a constant, and over tightening of the tightening bolt and nut is prevented, The work efficiency at the time of construction is increased.

本発明器具は前記の嵌合ハゼ部Ａに装着する金具で、下方開口コの字状の本体Ｂにおいて所定の構成部を形成したものである。尚嵌合ハゼ部Ａに添う方向を前後方向として以下説明する。   The instrument of the present invention is a metal fitting to be mounted on the above-mentioned fitting gouge part A, and a predetermined component is formed in a main body B having a U-shaped lower opening. In the following description, the direction along the fitting seam A will be described as the front-rear direction.

本体Ｂの基本構成は、上面板部１と、左右に対面する対向板部２ａ，２ｂと、対向板部２ａ，２ｂの前後縁を内方に折曲して形成した折曲板部３ａ，３ｂと、対向板部２ａ，２ｂの下縁部分の一部を内方に折曲して形成した挟持安定板部４ａ，４ｂと、対向板部２ａ，２ｂの下縁部分の一部を外方に折曲して形成した載置安定板部５ａ，５ｂとを備え、適宜な他部材取付部６を設けているものである。   The basic structure of the main body B includes an upper surface plate portion 1, opposing plate portions 2a and 2b facing left and right, and a bent plate portion 3a formed by bending the front and rear edges of the opposite plate portions 2a and 2b inward. 3b, sandwiching stabilizing plate portions 4a and 4b formed by bending inward a part of the lower edge portion of the opposing plate portions 2a and 2b, and a part of the lower edge portion of the opposing plate portions 2a and 2b It is provided with mounting stabilization plate portions 5a and 5b formed by bending toward each other, and an appropriate other member mounting portion 6 is provided.

対向板部２ａ，２ｂには、緊締ボルト７を貫通装着し、対向板部２ｂから突出させたボルト軸に緊締ナット８を螺合して、対向板部２ａ，２ｂの挟圧操作を行うものである。   The opposing plate portions 2a and 2b are fitted with through-tightening bolts 7, and a tightening nut 8 is screwed onto a bolt shaft protruding from the opposing plate portion 2b to perform the clamping operation of the opposing plate portions 2a and 2b. It is.

折曲板部３ａ，３ｂは、器具装着時に嵌合ハゼ部Ａが邪魔にならないように切欠部３１としておき、且つ器具装着時に嵌合ハゼ部Ａにおける膨出中空部分に対面する個所に切欠部３１へ突出する挟持突起部３２を設けたものである。   The bent plate portions 3a and 3b are notched portions 31 so that the fitting gouge A does not get in the way when the instrument is mounted, and the cutout portions are formed at locations facing the bulging hollow portion of the fitting goby A when the instrument is mounted. A pinching protrusion 32 protruding to 31 is provided.

尚前記の挟持突起部３２は、先端を尖らせ、且つ膨出中空部分でも、左右方向において挟圧耐久力を備えた上方に偏った位置に対応させるのが好ましい。   The pinching protrusion 32 preferably has a sharpened tip and corresponds to an upwardly biased position having pinching durability in the left-right direction even in the bulging hollow portion.

更に前記の折曲板部３ａ，３ｂは、対向板部２ａ，２ｂを所定位置まで近接した際、即ち器具装着状態において、挟持突起部３２の嵌合ハゼ部（膨出中空部分）Ａへの食い込みが充分である位置でその端縁（衝突ストッパー部）３３が当接する長さを内方に張り出させたものである。   Furthermore, the bent plate portions 3a and 3b are arranged so that the opposing plate portions 2a and 2b are brought close to a predetermined position, that is, in a state where the instrument is mounted, to the fitting protrusion portion (bulging hollow portion) A of the holding projection portion 32. The length with which the end edge (collision stopper portion) 33 abuts at a position where the biting is sufficient protrudes inward.

また挟持安定板部４ａ，４ｂは、器具装着時に嵌合ハゼ部Ａにおける搾り部ｂ２の位置で、且つ前記搾り部ｂ２に当接する程度の内方突出長さとしてなる。更に載置安定板５ａ，５ｂは、器具装着時における屋根板上に位置するように設けたものである。   Moreover, the clamping stabilization board parts 4a and 4b become the inward protrusion length of the grade which contacts the said squeezing part b2 in the position of the squeezing part b2 in the fitting goby part A at the time of instrument mounting | wearing. Furthermore, the mounting stabilization plates 5a and 5b are provided so as to be positioned on the roof plate when the appliance is mounted.

他部材取付部６は、上面板部１と対向板部２ａ，２ｂの上方部分を前後に分割する溝部６１と、上面板部１に設けた透孔６２で構成されるものである。   The other member mounting portion 6 is configured by a groove portion 61 that divides the upper portion of the upper surface plate portion 1 and the opposing plate portions 2 a and 2 b into the front and rear, and a through hole 62 provided in the upper surface plate portion 1.

而して前記金具本体Ｂには、例えば雪止め金具として使用する場合には、図１（イ）に示すように、雪止め板Ｃを溝部６１に挿着し、透孔６２を利用して止着ボルトＤで雪止め板Ｃを取り付けたり、或いは図１（ロ）に示すように透孔６２を利用して雪止めアングルＥの抜け止め部材Ｆを付設して使用するものである。   Thus, for example, in the case of using as a snow stopper metal fitting in the metal fitting body B, as shown in FIG. A snow stop plate C is attached with a fixing bolt D, or a retaining member F having a snow stop angle E is provided by using a through hole 62 as shown in FIG.

そして前記の本体Ｂを嵌合ハゼ部Ａに取り付けるには、従前の金具と同様に本体Ｂを嵌合ハゼ部Ａに跨がせて、緊締ボルト７に螺合した緊締ナット８を締め付け、対向板部２ａ，２ｂを近接させ、挟持突起部３２を嵌合ハゼ部Ａの膨出中空部分に食い込ませてなるものである。   In order to attach the main body B to the fitting seam A, the main body B is straddled over the fitting seam A as in the case of the conventional metal fitting, and the tightening nut 8 screwed to the tightening bolt 7 is tightened and opposed. The plate portions 2a and 2b are brought close to each other, and the sandwiching projection portion 32 is bitten into the bulging hollow portion of the fitting gouge portion A.

従って嵌合ハゼ部Ａの中空膨出部分に挟持突起３２を食い込ませて、器具本体の屋根への固定を実現するもので、前記の食い込みによって充分な固着力（ずり落ち抵抗：前後方向への引張試験において引張強度２５０〜３００ｋｇｆ以上で金具の滑りが生じなかった）を備えるものである。   Therefore, the clamping protrusion 32 is bitten into the hollow bulging portion of the fitting gouge A, and the fixture body is fixed to the roof. By the biting, sufficient fixing force (slipping resistance: in the front-rear direction) is realized. In the tensile test, the metal fitting was not slipped at a tensile strength of 250 to 300 kgf or more.

しかも折曲板部２ａ，２ｂの端縁（衝突ストッパー部）が当接すると、緊締ナット８の操作による対向板部２ａ，２ｂの接近が阻止され、挟持突起部３２の食い込みも当該状態で停止してしまうので、器具本体Ｂの嵌合ハゼ部Ａへの装着作業に際しては、衝突ストッパー部３３の当接位置まで緊締ナット８の操作が為されることになるので、締め付け過ぎの注意をする必要が無く、作業能率が向上するものである。   Moreover, when the end edges (collision stopper portions) of the bent plate portions 2a and 2b come into contact with each other, the approach of the opposing plate portions 2a and 2b due to the operation of the tightening nut 8 is prevented, and the biting of the holding projection 32 is also stopped in this state. Therefore, when attaching the instrument main body B to the fitting seam A, the tightening nut 8 is operated up to the contact position of the collision stopper 33, so be careful not to over-tighten. There is no need to improve the work efficiency.

尚本発明は前記の実施形態に限定されるものではなく、挟持突起部３２及び衝突ストッパー部３３を折曲板部３ａ，３ｂに形成することなく、対向板部２ａ，２ｂから切り起こし等で直接形成するようにしても良い。また取付部も前記構成に限定されるものではなく、対向板部２ａ，２ｂの前後端を作用外方に張り出させて取付部とするようにしても良い。   In addition, this invention is not limited to the said embodiment, It does not form the clamping protrusion part 32 and the collision stopper part 33 in the bending board parts 3a and 3b, but cuts and raises from the opposing board parts 2a and 2b etc. You may make it form directly. Further, the mounting portion is not limited to the above-described configuration, and the front and rear ends of the opposing plate portions 2a and 2b may be projected outward to form the mounting portion.
