Description

この発明は、物流施設等の鉄骨系建物等における建物躯体への外壁パネルの取付け構造に関する。 The present invention relates to a mounting structure of the outer wall panels to the building structures in steel-framed buildings, etc. distribution facilities.

物流施設、コンビニエンスストア等の建物の外壁では、ロックウールなどの不燃断熱材を鋼板で挟み込んだ構造の金属サンドイッチ構造の耐火パネルである外壁パネルを、上下に複数枚並べて構築するものがある。このような外壁を施工するのに、従来は、図１４のようにスラブ５１，梁５３、５４、柱（図示せず）等からなる建物躯体５０に、下地となる胴縁５３を先行して取付け、この胴縁５３に前記複数枚の外壁パネル５２を取り付ける。この場合、スラブ５１の上部に胴縁固定用のピース５５を取り付けてそこに胴縁５３を固定する。その胴縁５３に、外部足場（図示せず）を利用して、足場側から外壁パネル５２を下段から順にビスで固定していく。   Some of the outer walls of buildings such as logistics facilities and convenience stores are constructed by arranging a plurality of outer wall panels, which are fireproof panels of a metal sandwich structure in which a non-combustible heat insulating material such as rock wool is sandwiched between steel plates. In order to construct such an outer wall, conventionally, as shown in FIG. 14, a body frame 53 as a foundation is preceded by a building housing 50 including a slab 51, beams 53 and 54, columns (not shown), and the like. The plurality of outer wall panels 52 are attached to the trunk edge 53. In this case, a piece 55 for fixing the trunk edge is attached to the upper part of the slab 51 and the trunk edge 53 is fixed thereto. The outer wall panel 52 is fixed to the trunk edge 53 with a screw in order from the lower stage using an external scaffold (not shown).

外壁パネル５２の胴縁５３へのビス固定作業は、胴縁５３と反対側に設けられた足場から行われ、外壁パネル５２が外壁面を構成する場合は、外部足場から行われる。この時、外壁パネル５２は１枚１枚ウインチなどによって吊り上げられ、胴縁５３に取り付けられる。   The screw fixing work to the trunk edge 53 of the outer wall panel 52 is performed from a scaffold provided on the opposite side to the trunk edge 53, and when the outer wall panel 52 constitutes the outer wall surface, it is performed from the outer scaffold. At this time, the outer wall panels 52 are lifted one by one by a winch or the like and attached to the trunk edge 53.

近年、建築施工では省力化や短工期化が求められているが、上記した従来の外壁パネルの施工方法では、外壁パネル５２を１枚ずつ吊り上げ、建物躯体５０の胴縁５３に取り付けるので、省力化や短工期化は期待できない。また、外壁パネル５２を胴縁５３に取付ける作業は高所作業となるため、建物躯体５０の外周に足場が必要であり、外壁パネル５２の取付け施工の間、足場を解体できないことから、例えば外構工事など足場に影響する工事が滞るなどの問題がある。   In recent years, there has been a demand for labor saving and shortening the construction period in building construction. However, in the above-described conventional method for constructing an outer wall panel, the outer wall panels 52 are lifted one by one and attached to the trunk edge 53 of the building frame 50. No shortening or shortening of construction period can be expected. Further, since the work of attaching the outer wall panel 52 to the trunk edge 53 is a work at a high place, a scaffold is required on the outer periphery of the building housing 50, and the scaffold cannot be disassembled during the installation work of the outer wall panel 52. There is a problem that construction works that affect the scaffolding such as construction work are delayed.

このような課題を解決する対策として、建物躯体５０に取付けられる複数枚の外壁パネル５２を、下地となる胴縁５３に地組みして下地一体型の外壁パネルユニット（図示せず）としておき、この下地一体化外壁パネルを一度に吊り上げて建物躯体の外壁パネル取付面に取付けることで、省力化や短工期化を図ることを考えた。   As a countermeasure to solve such a problem, a plurality of outer wall panels 52 attached to the building housing 50 are grounded on a trunk edge 53 serving as a base to form a base-integrated outer wall panel unit (not shown). We thought about saving labor and shortening the construction period by lifting this foundation-integrated outer wall panel at once and mounting it on the outer wall panel mounting surface of the building frame.

しかし、その場合、図１４に示す従来の外壁パネル５２の胴縁５３の取付構造では、胴縁５３が上下のスラブ５１で挟まれるように取付けられている。そのため、下地一体型の外壁パネルユニットを取付けようとする場合、外壁パネルユニットの胴縁５３を上下のスラブ５１，５１間に嵌合させる作業が必要となり、その嵌合作業が非常に困難となる。さらに、下地一体型の外壁パネルユニットの取付けの効率が非常に悪くなる。そのため、下地一体型の外壁パネルユニットとして建物躯体へ取付ける施工方法の実現が難しい。   However, in that case, in the conventional structure for attaching the trunk edge 53 of the outer wall panel 52 shown in FIG. 14, the trunk edge 53 is attached so as to be sandwiched between the upper and lower slabs 51. Therefore, when it is intended to mount the base wall-integrated outer wall panel unit, it is necessary to fit the trunk edge 53 of the outer wall panel unit between the upper and lower slabs 51, 51, and the fitting work becomes very difficult. . Furthermore, the efficiency of attachment of the base-integrated outer wall panel unit becomes very poor. Therefore, it is difficult to realize a construction method for attaching to a building frame as a base-integrated outer wall panel unit.

この発明の目的は、複数枚の外壁パネルを下地となる胴縁と共に下地一体型の外壁パネルユニットとして纏めて建物躯体に取付けることができ、かつその取付け時に胴縁を上下スラブ間へ嵌合する作業が不要で作業性が良く、省力化、短工期化が可能な外壁パネルの取付け構造を提供することである。 An object of the present invention is to assemble a plurality of outer wall panels together with a trunk edge as a foundation as a foundation-integrated outer wall panel unit and attach it to a building frame, and fit the trunk edge between the upper and lower slabs at the time of attachment. work well unnecessary and workability, it is to provide a labor-saving, the mounting structure of a short construction period reduction can outer wall panels.

この発明の外壁パネルの取付け構造は、上下方向に並ぶ複数枚の外壁パネルが、この外壁パネルの横幅方向の複数箇所で上下方向に延びる複数本の胴縁に取付けて外壁パネルユニットとされ、この外壁パネルユニットの前記胴縁が、建物躯体のスラブよりも屋外側に位置して、前記外壁パネルユニットが前記建物躯体に取付けられることを基本構成とする。 Mounting structure of the outer wall panels of the invention, the outer wall panels of a plurality arranged in a vertical direction, is an outer wall panel unit is attached to the plurality of furring strips extending vertically at a plurality of positions in the width direction of the outer wall panel, the the barrel edge of the outer wall panel unit, located on the outdoor side of the slab of the building structures to be the basic structure of the exterior wall panel unit is eclipsed attached to the building structures.

この構成によると、複数枚の外壁パネルを胴縁に取付けて下地一体型の外壁パネルユニットとしたため、複数の外壁パネルを纏めて建物躯体に取付けることができる。そのため、個々の外壁パネルを１枚ずつ建物躯体に取付ける従来の外壁パネルの取付け構造に比べて、省力化、短工期化が可能となる。外壁パネルユニットの胴縁を建物躯体に取付ける作業は、建物躯体内のスラブや梁上等から行えるため、建物躯体の外周に従来は必要であった足場が不要で、足場の構築，撤去作業が不要になるうえ、足場に起因した工事の遅延などの影響も少なくなる。
また、外壁パネルユニットの胴縁を、建物躯体のスラブよりも屋外側に位置させる。そのため、下地一体型の外壁パネルユニットとして纏めて建物躯体に取付ける構成でありながら、胴縁を上下スラブ間へ嵌合する作業が不要で困難な作業を伴わず、下地一体型の外壁パネルユニットを建物躯体に簡単かつ迅速に取り付けることができる。 According to this configuration, since the plurality of outer wall panels are attached to the trunk edge to form the base-integrated outer wall panel unit, the plurality of outer wall panels can be collectively attached to the building frame. Therefore, it is possible to save labor and shorten the construction period compared to a conventional outer wall panel mounting structure in which individual outer wall panels are mounted one by one on the building frame. Since the work of attaching the outer edge of the outer wall panel unit to the building frame can be performed from the slabs or beams on the building frame, there is no need for a scaffold on the outer periphery of the building frame. In addition to being unnecessary, the impact of construction delays due to the scaffolding is reduced.
Moreover, the trunk edge of the outer wall panel unit is positioned on the outdoor side of the slab of the building frame. For this reason, the base-integrated outer wall panel unit can be attached to the building frame as a base-integrated outer wall panel unit without the need to fit the trunk edge between the upper and lower slabs. It can be easily and quickly attached to the building frame.

Opposing ends of the body edges of the matching outer wall panel units may be connected to each other. The beam may be a beam that supports a slab, a wind-resistant beam at an intermediate height position between upper and lower slabs , or the like. In this way, when the trunk edge is positioned so as to straddle the beam or slab of the building frame, the scaffold construction is further facilitated.

上記基本構成において、前記外壁パネルは、不燃断熱材を鋼板で挟み込んだ金属サンドイッチパネルであっても良い。このような金属サンドイッチパネルを用いると、軽量で不燃性、断熱性の良い外壁が構築できる。このような金属サンドイッチパネルを用いた外壁に、この発明を適用することで、その胴縁を建物躯体のスラブよりも屋外側に位置させる外壁パネルの取付け構造とした上記の各効果が効果的に発揮される。 In the above basic configuration , the outer wall panel may be a metal sandwich panel in which an incombustible heat insulating material is sandwiched between steel plates. When such a metal sandwich panel is used, an outer wall that is lightweight, incombustible, and has good heat insulation can be constructed. By applying the present invention to the outer wall using such a metal sandwich panel, each of the above effects can be effectively achieved as an outer wall panel mounting structure in which the trunk edge is positioned on the outdoor side of the slab of the building frame.

この発明の第１の実施形態を図１ないし図１０と共に説明する。この外壁パネルの取付け構造が適用される建物は、例えば物流施設となる倉庫やコンビニエンスストア等の鉄骨系建物であり、各階の床は、デッキプレート上にコンクリートを打設したスラブ３１で構成される。   A first embodiment of the present invention will be described with reference to FIGS. Buildings to which this outer wall panel mounting structure is applied are, for example, steel-framed buildings such as warehouses and convenience stores that serve as distribution facilities, and the floors of each floor are composed of slabs 31 in which concrete is placed on deck plates. .

図１において、この外壁パネルの取付け構造は、上下方向に並ぶ複数枚の外壁パネル２２を、この外壁パネル２２の横幅方向の複数箇所で上下方向に延びる複数本の胴縁２３に取付けて図３，図１０に示すような外壁パネルユニット２１とし、この外壁パネルユニット２１の前記胴縁２３を、図１のように建物躯体２６のスラブ３１よりも屋外側に位置させて、前記外壁パネルユニット２１を建物躯体２６に取付けたものである。外壁パネルユニット２１は、上下左右に複数並べて設置される。   In FIG. 1, the outer wall panel mounting structure is constructed by mounting a plurality of outer wall panels 22 arranged in the vertical direction on a plurality of trunk edges 23 extending in the vertical direction at a plurality of positions in the lateral width direction of the outer wall panel 22. , The outer wall panel unit 21 as shown in FIG. 10, and the trunk edge 23 of the outer wall panel unit 21 is positioned on the outdoor side of the slab 31 of the building housing 26 as shown in FIG. Is attached to the building frame 26. A plurality of outer wall panel units 21 are installed side by side in the vertical and horizontal directions.

外壁パネル２２は、耐火性および断熱性を有する横長の耐火パネルである。外壁パネル２２は、具体例を挙げると、図４に示すように、不燃断熱材２７を屋外側および屋内側の鋼板２８，２９で挟み込んだ金属サンドイッチパネルとされる。不燃断熱材２７は、ロックウール等の非定形の材料であるが、けい酸カルシウム板や石膏ボード等であっても良い。
図５は、上下に隣り合う外壁パネル２２，２２の継手部分を断面図で示している。上下の外壁パネル２２，２２は、互いに嵌まり合う突条部分および凹溝条部分を有し、その蛇行した嵌まり合い面で雨水や風の侵入を阻止し、または侵入した雨水が流下し易くなる継手形状とされる。 The outer wall panel 22 is a horizontally long fireproof panel having fire resistance and heat insulation. For example, as shown in FIG. 4, the outer wall panel 22 is a metal sandwich panel in which an incombustible heat insulating material 27 is sandwiched between steel plates 28 and 29 on the outdoor side and the indoor side. The incombustible heat insulating material 27 is an amorphous material such as rock wool, but may be a calcium silicate plate or a gypsum board.
FIG. 5 is a cross-sectional view showing joint portions of the outer wall panels 22 and 22 adjacent to each other in the vertical direction. The upper and lower outer wall panels 22 and 22 have a protruding ridge portion and a recessed groove portion that fit together, and the meandering fitting surface prevents rainwater or wind from entering, or the rainwater that has entered easily flows down. The joint shape is as follows.

図１において、胴縁２３は、建物躯体２６への外壁パネル２２の取付け用の下地となる棒状の下部材であって、ここでは断面Ｃ字状の軽量形鋼のリップ溝形鋼が用いられている。この胴縁２３は、そのＣ字の開口側が胴縁２３の並び方向つまり外壁パネル２２の幅方向を向くように設けられる。胴縁２３は、この他に角パイプ等の軽量形鋼であっても良く、またリップ溝形鋼と角パイプとを混在させても良い。   In FIG. 1, the trunk edge 23 is a rod-like lower member that serves as a base for mounting the outer wall panel 22 to the building frame 26, and here, a lip groove steel of a lightweight section steel having a C-shaped cross section is used. ing. The trunk edge 23 is provided so that the C-shaped opening side faces the arrangement direction of the trunk edges 23, that is, the width direction of the outer wall panel 22. In addition, the body edge 23 may be a lightweight steel such as a square pipe, or a lip groove steel and a square pipe may be mixed.

外壁パネル２２の胴縁２３への取付けには、図２（Ｂ）に示すようにドリル付きタッピングビス等の軸状の固着具３０が用いられる。同図において、固着具３０の頭部が外壁パネル２２の表面から沈み込んで図示されているのは、外壁パネル２２における継手部分の凹み部２２ａ（図４、図５）内に固着具３０の頭部が位置しているためである。   For attaching the outer wall panel 22 to the body edge 23, as shown in FIG. 2B, a shaft-like fixing tool 30 such as a tapping screw with a drill is used. In the same figure, the head of the fixing tool 30 is shown sinking from the surface of the outer wall panel 22, and the fixing tool 30 is placed in the recess 22 a (FIG. 4, FIG. 5) of the joint portion of the outer wall panel 22. This is because the head is located.

図１において、外壁パネルユニット２１の胴縁２３を建物躯体２６に取付ける構造としては、建物躯体２６のスラブ３１の端部および耐風梁３２にファスナ１４を取付け、これらファスナ１４に、外壁パネルユニット２１の胴縁２３をボルトまたは溶接で固定する構造とされる。スラブ３１は、建物躯体２６の梁４１上にデッキプレートを載せ、その上にコンクリートを打設した構成とされ、外壁側の木口面は内向きの溝形鋼等の形鋼３１ａで構成されている。スラブ３１のファスナ１４は、上記形鋼３１ａの上面に溶接等で固定されている。ファスナ１４は、Ｌ形鋼の切片等からなり、各胴縁２３と対応する箇所に部分的に設けられている。   In FIG. 1, as a structure for attaching the trunk edge 23 of the outer wall panel unit 21 to the building housing 26, the fastener 14 is attached to the end of the slab 31 of the building housing 26 and the wind-resistant beam 32, and the outer wall panel unit 21 is attached to these fasteners 14. The body edge 23 is fixed with bolts or welding. The slab 31 has a structure in which a deck plate is placed on the beam 41 of the building frame 26, and concrete is placed thereon, and the end face of the outer wall side is formed of a shape steel 31a such as an inward grooved steel. Yes. The fastener 14 of the slab 31 is fixed to the upper surface of the shape steel 31a by welding or the like. The fastener 14 is made of an L-shaped steel piece or the like, and is partially provided at a portion corresponding to each trunk edge 23.

図２（Ｂ）は胴縁２３のファスナ１４への取付部分を拡大して示したものである。同図の例では、ファスナ１４の横片１４ａが形鋼３１ａの上面に固定され、立片１４ｂに胴縁２３がボルト４２およびナット４３により固定される。ナット４３は、リップ溝形の胴縁２３のフランジ内面に溶接等で固定してもよく、またボルト締め時に屋内側から固定しても良い。なお、胴縁２３は、ファスナ１４に対しボルト４２に代えて溶接で固定しても良い。   FIG. 2B is an enlarged view of the attachment portion of the trunk edge 23 to the fastener 14. In the example of the figure, the lateral piece 14a of the fastener 14 is fixed to the upper surface of the section steel 31a, and the trunk edge 23 is fixed to the standing piece 14b by bolts 42 and nuts 43. The nut 43 may be fixed to the inner surface of the flange of the lip groove-shaped body edge 23 by welding or the like, or may be fixed from the indoor side when bolted. The trunk edge 23 may be fixed to the fastener 14 by welding instead of the bolt 42.

図１において、耐風梁３２は、上下のスラブ３１，３１間の中間高さ位置に設けられて外壁パネル２２に作用する風荷重を内側から支える梁である。耐風梁３２に対する外壁パネルユニット２１の胴縁２３の取付けも、スラブ３１への取付けと同様にファスナ１４とボルト・ナットまたは溶接で行われている。   In FIG. 1, a wind resistant beam 32 is a beam that is provided at an intermediate height position between upper and lower slabs 31 and 31 and supports a wind load acting on the outer wall panel 22 from the inside. The body edge 23 of the outer wall panel unit 21 is attached to the wind-resistant beam 32 by fasteners 14 and bolts / nuts or welding in the same manner as the attachment to the slab 31.

外壁パネルユニット２１の高さは、同図の例では上下のスラブ３１，３１間の高さよりも低く、各外壁パネルユニット２１の胴縁２３は、スラブ３１、梁４１、及び耐風梁３２のいずれか対して上下に跨っている。上下に並ぶ外壁パネルユニット２１，２１は、胴縁２３の対向する端部が相互に連結されている。そのため、同図の例では、各外壁パネルユニット２１の胴縁２３の下部は直接には建物躯体２６に取付けられていないが、下側に連結された胴縁２３の上部が建物躯体２６に取付けられることで、胴縁２３の下部も建物躯体２６に堅固に支持される。   The height of the outer wall panel unit 21 is lower than the height between the upper and lower slabs 31, 31 in the example of the figure, and the trunk edge 23 of each outer wall panel unit 21 is any of the slab 31, the beam 41, and the wind resistant beam 32. On the other hand, it straddles up and down. The outer wall panel units 21, 21 arranged vertically are connected to each other at opposite ends of the trunk edge 23. Therefore, in the example of the figure, the lower part of the trunk edge 23 of each outer wall panel unit 21 is not directly attached to the building frame 26, but the upper part of the trunk edge 23 connected to the lower side is attached to the building frame 26. As a result, the lower portion of the trunk edge 23 is also firmly supported by the building frame 26.

上下の胴縁２３，２３の相互の連結は、この例では図６（Ａ）に拡大して示すように、両胴縁２３の端部外面に跨がって配置したジョイントプレート１５をそれぞれ両胴縁２３に、ボルト１６であるいは溶接で固定することにより行われている。ジョイントプレート１５は、同図（Ｂ）のように胴縁２３の内面に配置しても良い。   In this example, the upper and lower body edges 23 are connected to each other by connecting the joint plates 15 arranged over the outer surface of the end portions of both body edges 23 as shown in FIG. 6A. It is performed by fixing to the trunk edge 23 with a bolt 16 or by welding. The joint plate 15 may be disposed on the inner surface of the trunk edge 23 as shown in FIG.

両胴縁２３，２３の端部同士の連結は、この他に図７のように、中空部材である両胴縁２３，２３の端部間に渡って嵌まり込む嵌込み部材１７を設けることで行っても良い。嵌込み部材１７は、例えば上下のいずれかの胴縁に一部突出状態に嵌め込んで固定しておき、上側の外壁パネルユニット２１の設置時にその一部突出状態とした嵌込み部材１７の突出部分に胴縁２３を嵌め込む。この嵌め込みの後、嵌め込み部分を溶接やボルトで固定しても良いが、必ずしも固定しなくても良い。   In addition to this, as shown in FIG. 7, the end portions of both body edges 23, 23 are connected by providing a fitting member 17 that fits between the end portions of both body edges 23, 23 that are hollow members. You can go there. The fitting member 17 is, for example, partially fitted into and fixed to one of the upper and lower body edges and fixed, and the fitting member 17 is projected in a partially protruding state when the upper outer wall panel unit 21 is installed. The trunk edge 23 is fitted into the part. After this fitting, the fitting part may be fixed with welding or a bolt, but it is not necessarily fixed.

なお、図１（Ｂ）および図２（Ａ）に示すように、スラブ３１と外壁パネル２２との間には、外壁パネルユニット２１の胴縁２３をスラブ３１よりも屋外側に位置させることによって、スラブ３１の縁に沿う隙間ｄが生じるが、この隙間ｄは、モルタルやロックウール等の耐火材の充填部４５によって塞ぐ。   In addition, as shown in FIG. 1 (B) and FIG. 2 (A), between the slab 31 and the outer wall panel 22, by positioning the trunk edge 23 of the outer wall panel unit 21 on the outdoor side from the slab 31. A gap d is formed along the edge of the slab 31, and the gap d is closed by a filling portion 45 of a refractory material such as mortar or rock wool.

上記隙間ｄを小さくするために、図１１，図１２に示すように、スラブ３１の縁に切欠部３１ｂを設け、この切欠部３１ｂ内に胴縁２３を配置しても良い。切欠部３１ｂ内は上記耐火材を充填した充填部４５とする。この場合、切欠部３１ｂがない箇所では、スラブ３１の縁に外壁パネル２２が接して隙間ｄが生じないようにしても良く、また隙間ｄが少し残るようにしてその隙間ｄに上記耐火材の充填部４５で塞いでも良い。   In order to reduce the gap d, as shown in FIGS. 11 and 12, a notch 31b may be provided at the edge of the slab 31, and the body edge 23 may be disposed in the notch 31b. The inside of the cutout portion 31b is a filling portion 45 filled with the refractory material. In this case, in a place where the notch portion 31b is not provided, the outer wall panel 22 may be in contact with the edge of the slab 31 so that the gap d is not generated, and the gap d is left a little so that the refractory material can be left in the gap d. The filling portion 45 may be used for blocking.

図８〜図１０は、外壁パネルユニット２１の組み立てから、建物躯体２６への取付までの過程を示す。外壁パネルユニット２１を組み立てる地組み過程では、例えば図８，９に示す地組架台１を用いる。この地組架台１は、鉄骨で組まれた地組架台本体２に、下側および上側の治具取付桟１２，１３が互いに上下に位置して設けられ、これら治具取付桟１２，１３に胴縁支持用の複数の下端固定治具３および上側固定治具４が取付けられている。また、地組架台本体２の上端にクレーン等のパネル揚重装置２４が設置されている。   FIGS. 8-10 shows the process from the assembly of the outer wall panel unit 21 to the attachment to the building frame 26.
