Description

本発明は、圧潰防止具及び複合パネルに関する。   The present invention relates to a crush prevention device and a composite panel.

従来から、軸組架構の外周部を構成する外周軸組架構の屋外側に断熱部材を配置して断熱層を形成し、断熱層の更に屋外側に軽量気泡コンクリート(ALC)の帳壁を配置して外装仕上げ層を形成する建物の外周壁構造が知られている(特許文献1参照)。また、特許文献1には、ALCパネルに設けたボルトを断熱部材としての断熱板の厚さ方向に貫通させて建物の軸組架構に締結する際に断熱板に作用する圧縮力に対抗するスリーブと、このスリーブと一体化された補強板とを備える圧潰防止具としての補強部材が開示されている。   Conventionally, a heat insulating member is formed on the outdoor side of the outer peripheral frame structure that forms the outer periphery of the shaft frame structure to form a heat insulating layer, and a lightweight aerated concrete (ALC) book wall is further arranged on the outdoor side of the heat insulating layer. And the outer peripheral wall structure of the building which forms an exterior finishing layer is known (refer patent document 1). Further, Patent Document 1 discloses a sleeve that opposes a compressive force acting on a heat insulating plate when a bolt provided on an ALC panel is passed through in a thickness direction of a heat insulating plate as a heat insulating member and fastened to a shaft frame structure of a building. And the reinforcement member as a crush prevention tool provided with the reinforcement board integrated with this sleeve is disclosed.

特許第4169659号公報Japanese Patent No. 4169659

ところで、特許文献1に開示された補強部材は、断熱板の両側から厚み方向と完全に平行して圧縮力が作用する際には、スリーブが圧縮力に対抗し、圧潰防止効果を十分に発揮することができるが、スリーブの一端のみに補強板が一体化されている構成であるため、断熱板に対する取り付けは容易であるものの、断熱板に作用する圧縮力の方向が厚み方向から若干ずれ、厚み方向と一致しない場合には、スリーブの周方向に均等に圧縮力が作用せず、スリーブの曲げ変形や、この曲げ変形によって断熱部材に局所的な潰れが生じるおそれがある。   By the way, the reinforcing member disclosed in Patent Document 1 has a sleeve that resists the compressive force when the compressive force acts completely in parallel with the thickness direction from both sides of the heat insulating plate, and sufficiently exhibits a crush preventing effect. Although it is a configuration in which the reinforcing plate is integrated only at one end of the sleeve, the mounting to the heat insulating plate is easy, but the direction of the compressive force acting on the heat insulating plate is slightly shifted from the thickness direction, When the thickness direction does not coincide with the thickness direction, the compressive force does not act evenly in the circumferential direction of the sleeve, and there is a possibility that the sleeve is bent or locally crushed by the bending deformation.

It is.

圧潰防止具1は、2枚のパネル間に挟み込まれる断熱部材に内蔵されるものであり、断熱部材が2枚のパネルにより挟み込まれる際に、2枚のパネルにより挟み込まれ、断熱部材が所定厚さ以下に潰れないようにするスペーサーとしての機能を有するものである。ここでは、2枚のパネル31及び33と、この2枚のパネル31及び33の間に挟み込まれる断熱部材32と、を備える複合パネル2において、圧潰防止具1を適用した構成を例示説明する。   The crush prevention device 1 is built in a heat insulating member sandwiched between two panels, and when the heat insulating member is sandwiched between two panels, the heat insulating member is sandwiched between the two panels, and the heat insulating member has a predetermined thickness. It has a function as a spacer that prevents it from being crushed below. Here, a configuration in which the crush prevention device 1 is applied to the composite panel 2 including the two panels 31 and 33 and the heat insulating member 32 sandwiched between the two panels 31 and 33 will be described as an example.

まず、圧潰防止具1単体の詳細について説明する。図1(a)に示すように、圧潰防止具1は、円筒状の筒部11と、この筒部11の一端に設けられた第1鍔部12と、筒部11の他端に設けられた第2鍔部13と、を備えている。第1鍔部12及び第2鍔部13の少なくとも一方の鍔部は、筒部11に対して着脱可能に装着される。本実施形態では、第1鍔部12は筒部11と一体で成形されており、第2鍔部13が筒部11に対して着脱可能に装着される。   First, the details of the crush prevention tool 1 alone will be described. As shown in FIG. 1A, the crush prevention device 1 is provided at a cylindrical tube portion 11, a first flange portion 12 provided at one end of the tube portion 11, and the other end of the tube portion 11. A second collar 13. At least one collar part of the 1st collar part 12 and the 2nd collar part 13 is attached with respect to the cylinder part 11 so that attachment or detachment is possible. In this embodiment, the 1st collar part 12 is shape | molded integrally with the cylinder part 11, and the 2nd collar part 13 is mounted | worn with respect to the cylinder part 11 so that attachment or detachment is possible.

より具体的に、本実施形態の圧潰防止具1は、図1(b)に示す筒状部材21と、図1(c)に示す鍔部材22との2部材により構成されている。図1(b)に示すように、筒状部材21は、筒部11と、この筒部11の一端から径方向外側に突設された環状の第1鍔部12と、を備えている。第1鍔部12の中央部には開口12aが形成されており、筒状部材21は、筒部11の軸方向において貫通した貫通孔15を区画している。   More specifically, the anti-crush device 1 of the present embodiment is composed of two members, a cylindrical member 21 shown in FIG. 1 (b) and a flange member 22 shown in FIG. 1 (c). As shown in FIG. 1B, the tubular member 21 includes a tubular portion 11 and an annular first flange portion 12 that protrudes radially outward from one end of the tubular portion 11. An opening 12 a is formed in the central portion of the first flange portion 12, and the tubular member 21 defines a through hole 15 that penetrates in the axial direction of the tubular portion 11.

図1(c)に示すように、鍔部材22は、第2鍔部13と、この第2鍔部13の一方の面から突設されており、筒状部材21の筒部11内に挿入されて筒部11と接続される円筒状の接続部14と、を備えている。第2鍔部13の中央部には開口13aが形成されており、鍔部材22は、接続部14の軸方向において貫通した貫通孔16を区画している。なお、接続部14は、第2鍔部13と一体で成形されている。   As shown in FIG. 1 (c), the flange member 22 protrudes from the second flange portion 13 and one surface of the second flange portion 13 and is inserted into the tube portion 11 of the tubular member 21. And a cylindrical connecting portion 14 connected to the cylindrical portion 11. An opening 13 a is formed in the center portion of the second flange portion 13, and the flange member 22 defines a through hole 16 penetrating in the axial direction of the connection portion 14. The connecting portion 14 is formed integrally with the second flange portion 13.

図1(a)に示すように、鍔部材22は、筒状部材21の筒部11のうち、第1鍔部12が一体成形されている一端とは反対側の他端に装着される。具体的に、筒部11の他端から接続部14が挿入されることにより、鍔部材22は筒状部材21に装着される。なお、筒部11の他端が第2鍔部13における第1鍔部12と対向する表面に当接するまで、接続部14を筒部11内に挿入することにより、筒状部材21に対する鍔部材22の装着は完了する。筒部11の内径は接続部14の外径と略等しく形成されているため、接続部14は、接続部14の外周面が筒部11の内周面と当接して密着することにより、筒部11により嵌合保持される。したがって、鍔部材22を、筒部11の軸方向において、接続部14の外周面と筒部11の内周面との間の摩擦力に抗して筒状部材21から離間する方向に引き抜くことにより、鍔部材22を筒状部材21から取り外すことができる。つまり、鍔部材22は、筒状部材21に対して着脱可能に装着される。なお、「着脱可能に装着」とは、例えば上述した摩擦力による嵌合や、後述するねじ接合(図6参照)など、着脱可能な取り付け手段を用いて装着されていることを意味するものである。   As shown to Fig.1 (a), the collar member 22 is mounted | worn with the other end on the opposite side to the end where the 1st collar part 12 is integrally molded among the cylinder parts 11 of the cylindrical member 21. As shown in FIG. Specifically, the flange member 22 is attached to the tubular member 21 by inserting the connecting portion 14 from the other end of the tubular portion 11. In addition, the flange member with respect to the cylindrical member 21 is inserted by inserting the connection part 14 into the cylinder part 11 until the other end of the cylinder part 11 contacts the surface of the second flange part 13 facing the first flange part 12. The installation of 22 is completed. Since the inner diameter of the cylindrical portion 11 is formed to be substantially equal to the outer diameter of the connecting portion 14, the connecting portion 14 is in contact with the inner peripheral surface of the cylindrical portion 11 in close contact with the inner peripheral surface of the cylindrical portion 11. The portion 11 is fitted and held. Therefore, the flange member 22 is pulled out in the direction away from the cylindrical member 21 against the frictional force between the outer peripheral surface of the connecting portion 14 and the inner peripheral surface of the cylindrical portion 11 in the axial direction of the cylindrical portion 11. Thus, the flange member 22 can be removed from the tubular member 21. That is, the flange member 22 is detachably attached to the tubular member 21. Note that “removably attached” means that the attachment is made by using a detachable attachment means such as the above-described frictional force fitting or screw joining (see FIG. 6) described later. is there.

ここで、図1(a)に示すように、本実施形態の圧潰防止具1は、筒状部材21に鍔部材22が装着された状態では、筒状部材21の貫通孔15と鍔部材22の貫通孔16とが連通して繋がり、筒部11の軸方向(接続部14の軸方向と同じ方向)において第1鍔部12の開口12aから第2鍔部13の開口13aまで貫通する連通孔17を区画する。   Here, as shown in FIG. 1A, the crush prevention device 1 of the present embodiment has the through-hole 15 of the tubular member 21 and the heel member 22 in a state where the heel member 22 is attached to the tubular member 21. The through hole 16 communicates with and communicates with each other and penetrates from the opening 12a of the first flange 12 to the opening 13a of the second flange 13 in the axial direction of the cylindrical portion 11 (the same direction as the axial direction of the connecting portion 14). A hole 17 is defined.

なお、圧潰防止具1は金属材料から構成されている。但し、硬質の合成樹脂材料により形成することも可能であり、かかる場合には、筒部11を備える筒状部材21は、筒部11から着脱可能な第2鍔部13を備える鍔部材22よりも断熱性の高い樹脂材料により形成されることが好ましい。   In addition, the crush prevention tool 1 is comprised from the metal material. However, it can also be formed of a hard synthetic resin material. In such a case, the cylindrical member 21 including the cylindrical portion 11 is more than the flange member 22 including the second flange portion 13 that is detachable from the cylindrical portion 11. Is preferably formed of a resin material having high heat insulating properties.

以下、上述した圧潰防止具1を備える複合パネル2の詳細について説明する。   Hereinafter, the detail of the composite panel 2 provided with the crush prevention tool 1 mentioned above is demonstrated.

複合パネル2は、建物の軸組架構の周囲に連接され、建物の外壁を構成するものである。このような建物としては、例えば、鉄骨造の軸組みを有する2階建ての工業化住宅が挙げられ、地盤に固定された鉄筋コンクリート造の基礎構造体と、柱や梁などの軸組部材で構成された軸組架構を有し、基礎構造体に固定された上部構造体と、で構成することができる。なお、軸組架構を構成する軸組部材は、予め規格化(標準化)されたものであり、予め工場にて製造されたのち建築現場に搬入されて組み立てられる。   The composite panel 2 is connected to the periphery of the building frame and constitutes the outer wall of the building. An example of such a building is a two-story industrialized house with a steel frame, and is composed of a reinforced concrete foundation structure fixed to the ground and a frame member such as a column or beam. And an upper structure fixed to the foundation structure. The shaft members constituting the shaft frame structure are standardized (standardized) in advance, and are manufactured in advance at a factory and then brought into a building site for assembly.

基礎構造体は、軸組架構の下方に位置し、軸組架構を支持する。例えば、基礎構造体は、鉄筋コンクリート造の断面T字状の布基礎であり、フーチング部と、基礎梁としての立ち上がり部とを備える。また、基礎構造体の立ち上がり部の上端部には、露出型固定柱脚工法により軸組架構の柱の柱脚を固定するための柱脚固定部が設けられ、アンカーボルトが立ち上がり部の上面から突出している。   The foundation structure is located below the shaft frame and supports the shaft frame. For example, the foundation structure is a cloth foundation having a T-shaped cross section made of reinforced concrete, and includes a footing portion and a rising portion as a foundation beam. In addition, a column base fixing part is provided at the upper end of the rising part of the foundation structure to fix the column base of the column of the frame frame by the exposed fixed column base method. It protrudes.

上部構造体は、複数の柱及び柱間に架設された複数の梁から構成される軸組架構と、この軸組架構の外周部を構成する外周軸組架構の屋外側を取り囲む外壁と、軸組架構の梁上に固定される床部材と、を備える。   The upper structure is composed of a plurality of columns and a plurality of beams installed between the columns, an outer wall that surrounds the outer side of the outer peripheral shaft structure that forms the outer periphery of the shaft structure, and a shaft. A floor member fixed on the beam of the frame structure.

軸組架構の柱は、例えば、角形鋼管で構成される。柱の側面の所定位置にはボルト孔が穿設され、大梁が接合される梁接合部が形成される。隣接する柱同士を連結する大梁は例えばH形鋼からなり、H形鋼の両端には、柱の梁接合部に形成されたボルト孔に対応する位置にボルト孔が穿設された接合プレートが溶接される。そして、梁接合部と接合プレートとが高力ボルトにより剛接合されることにより、柱と大梁とが接合される。   The column of the frame structure is composed of, for example, a square steel pipe. Bolt holes are drilled at predetermined positions on the side surfaces of the columns to form beam joints to which the large beams are joined. The large beam connecting adjacent columns is made of, for example, H-shaped steel, and at both ends of the H-shaped steel, there are joined plates having bolt holes drilled at positions corresponding to bolt holes formed in the beam joints of the columns. Welded. The beam joint and the joining plate are rigidly joined with a high-strength bolt, thereby joining the column and the large beam.

軸組架構における外周軸組架構の屋外側の周囲には外壁が取り付けられる。具体的に、外壁は、外周軸組架構の梁に対して位置が固定され、外周軸組架構の屋外側の周囲を取り囲む耐火層と、この耐火層の屋外側の周囲を取り囲む断熱層と、この断熱層の屋外側の周囲を取り囲む外装仕上げ層と、を備えている。なお、耐火層の屋内側には、下地材にビス等の締結部材により固定された内装仕上げ部材としての石膏ボードが設けられる。   An outer wall is attached to the periphery of the outer peripheral shaft frame structure in the shaft frame structure on the outdoor side. Specifically, a position of the outer wall is fixed with respect to the beam of the outer peripheral shaft frame structure, a fireproof layer surrounding the periphery of the outer peripheral shaft frame structure on the outdoor side, and a heat insulating layer surrounding the outer periphery of the fireproof layer, An exterior finish layer surrounding the periphery of the heat insulating layer on the outdoor side. In addition, the gypsum board as an interior finishing member fixed to the base material by fastening members such as screws is provided on the indoor side of the fireproof layer.

このように、軸組架構の外周軸組架構から屋外側に耐火層、断熱層の順に配置することにより、外周軸組架構の梁の位置に対して屋外側の位置であっても、断熱層よりも屋内側に位置する耐火層を外周軸組架構の梁に対して固定でき、外周軸組架構の梁の位置にかかわらず、耐火層の屋外側の表面に沿って外周軸組架構の周囲を連続的に取り囲むように断熱層を形成することが可能である。そのため、外周軸組架構の梁自体や、耐火層と外周軸組架構の梁との接続に用いる金物が断熱層の屋内側に位置し、断熱層を分断する位置に配置されないため、外周軸組架構の柱梁及び上記金物が屋内外間の熱移動の媒体(熱橋)となることを防ぐことができる。また、外周軸組架構の柱に対して屋外側の位置であっても、柱が断熱層に干渉せず、断熱層の厚みを薄くする必要がない。そのため、外周軸組架構の周囲全域に亘って、断熱層を一様な厚みで形成することが容易になり、断熱層内の位置によって断熱性能がばらつくことを抑制可能である。   In this way, by arranging the fireproof layer and the heat insulating layer in this order from the outer peripheral shaft frame structure of the shaft frame structure to the outdoor side, the heat insulating layer even at the outdoor position relative to the beam position of the outer shaft frame structure The refractory layer located on the indoor side can be fixed to the beam of the outer shaft frame structure, and the periphery of the outer shaft frame structure along the outdoor surface of the refractory layer regardless of the position of the beam of the outer shaft frame structure It is possible to form a heat insulating layer so as to continuously surround the substrate. For this reason, the outer shaft assembly is not located at the indoor side of the heat insulation layer, and the metal used to connect the fireproof layer to the beam of the outer shaft assembly is not located at the position where the heat insulation layer is divided. It is possible to prevent the column beam of the frame and the hardware from becoming a heat transfer medium (thermal bridge) between the inside and outside. Moreover, even if it is a position of the outdoor side with respect to the pillar of an outer periphery axial frame structure, a pillar does not interfere with a heat insulation layer, and it is not necessary to make thickness of a heat insulation layer thin. Therefore, it becomes easy to form the heat insulating layer with a uniform thickness over the entire periphery of the outer peripheral shaft frame structure, and it is possible to suppress variation in heat insulating performance depending on the position in the heat insulating layer.

更に、外周軸組架構の梁の屋内側を囲むように断熱部材を設ける必要がないため、外周軸組架構の梁の屋内側を囲むように無機繊維フェルト等を設ける梁の耐火被覆作業が容易である。特に、耐火層としてALCパネルを用いる場合には、外周軸組架構の梁の屋内側を囲む断熱部材を設けない構成とすれば、ALCパネルが含有する水分が屋内側に放出され易く、ALCパネルの調湿効果が発揮され易い。その結果、外周軸組架構の梁の表面に結露が生じることを抑制することができる。そのため、ALCパネルの含水率を規定値以下となるように乾燥させる工程が不要となるため施工性も向上する。また更に、本実施形態の外壁では、性能(耐火性能、断熱性能、防火性能)ごとに層を分けているため、いずれか1つの層が損失しても、他の層が担う性能に大きな影響を与えない。   Furthermore, since it is not necessary to provide a heat insulating member so as to surround the indoor side of the beam of the outer peripheral shaft frame structure, it is easy to carry out the fireproof coating of the beam provided with inorganic fiber felt or the like so as to surround the indoor side of the beam of the outer peripheral shaft frame structure. It is. In particular, when an ALC panel is used as the refractory layer, if the heat insulating member surrounding the indoor side of the beam of the outer peripheral shaft frame is not provided, the moisture contained in the ALC panel is easily released to the indoor side. The humidity control effect is easy to be demonstrated. As a result, it is possible to suppress the formation of condensation on the surface of the beam of the outer peripheral shaft frame. Therefore, since the process of drying so that the moisture content of an ALC panel may become below a specified value becomes unnecessary, workability is also improved. Furthermore, in the outer wall of this embodiment, since layers are divided for each performance (fire resistance performance, heat insulation performance, fire prevention performance), even if any one layer is lost, it greatly affects the performance of other layers. Not give.

上述した外壁は、図2及び図3に示す複合パネル2を連接することにより形成することができる。つまり、外壁は、厚み方向において耐火部材31、断熱部材32、外装仕上げ部材33の順に配置されて一体化された複合パネル2を軸組架構の周囲(外周軸組架構の周囲)に連接することにより構成することができ、かかる場合には、耐火部材31により上述した外壁の耐火層が形成され、断熱部材32により上述した外壁の断熱層が形成され、外装仕上げ部材33により上述した外壁の外装仕上げ層が形成される。   The outer wall described above can be formed by connecting the composite panels 2 shown in FIGS. That is, the outer wall is connected to the periphery of the shaft frame structure (the periphery of the outer peripheral shaft frame structure) by integrating and integrating the fireproof member 31, the heat insulating member 32, and the exterior finishing member 33 in this order in the thickness direction. In such a case, the above-described fireproof layer of the outer wall is formed by the fireproof member 31, the heat insulating layer of the outer wall is formed by the heat insulating member 32, and the exterior of the outer wall described above by the exterior finishing member 33. A finishing layer is formed.

図2に示すように、複合パネル2は、矩形板状に形成された、耐火部材31、断熱部材32及び外装仕上げ部材33を、間に通気層を設けることなく積層させて一体化したものであり、全体としても矩形板状の3層構造を有している。   As shown in FIG. 2, the composite panel 2 is formed by integrating a fireproof member 31, a heat insulating member 32, and an exterior finish member 33, which are formed in a rectangular plate shape, without stacking a ventilation layer therebetween. There is a three-layer structure of a rectangular plate as a whole.

外壁の耐火層を構成する複合パネル2の耐火部材31は、目地等が形成されていない平坦な表面を有するALCパネルにより構成されている。また、外壁の断熱層を構成する複合パネル2の断熱部材32は、例えばフェノールフォームなどの発泡樹脂パネルにより構成されている。更に、外壁の外装仕上げ層を構成する複合パネル2の外装仕上げ部材33は、耐火層を構成するALCパネルよりも薄く、表面上に防水性を有する塗膜が施されたALCパネルにより構成されている。塗膜は、外装仕上げ部材33のALCパネルの屋外側表面に吹き付け塗装等することにより形成することができる。なお、断熱層20bを構成する断熱部材22としては、上述したフェノールフォームの他に、ポリエチレンフォーム、ポリエチレンフォーム等の発泡樹脂パネルを用いることも可能である。また、断熱層20bを構成する断熱部材22として、グラスウール、ロックウール等の繊維系断熱材としてもよく、かかる場合には、比較的高密度なものであることが好ましい。   The fireproof member 31 of the composite panel 2 constituting the fireproof layer of the outer wall is composed of an ALC panel having a flat surface on which no joints or the like are formed. Moreover, the heat insulation member 32 of the composite panel 2 which comprises the heat insulation layer of an outer wall is comprised by foamed resin panels, such as a phenol foam, for example. Further, the exterior finishing member 33 of the composite panel 2 constituting the exterior finishing layer of the outer wall is composed of an ALC panel that is thinner than the ALC panel constituting the fireproof layer and has a waterproof coating on the surface. Yes. The coating film can be formed by spraying or the like on the outdoor side surface of the ALC panel of the exterior finishing member 33. In addition, as the heat insulation member 22 which comprises the heat insulation layer 20b, it is also possible to use foamed resin panels, such as a polyethylene foam and a polyethylene foam, other than the phenol foam mentioned above. Further, the heat insulating member 22 constituting the heat insulating layer 20b may be a fiber heat insulating material such as glass wool or rock wool. In such a case, it is preferable that the heat insulating member 22 has a relatively high density.

図3に示すように、複合パネル2は、厚み方向において、耐火部材31、断熱部材32及び外装仕上げ部材33を貫通する貫通孔が形成されており、複合パネル2の外装仕上げ部材33側の表面から貫通孔にボルト34を挿通し、耐火部材31側の表面からナット35を締め付けることにより、耐火部材31、断熱部材32及び外装仕上げ部材33は、ボルト34の頭部及びナット35に挟み込まれて一体化されている。なお、複合パネル2では、上述した貫通孔が複合パネル2の面内方向(厚み方向と直行する方向)に所定間隔を隔てて複数形成されており、各貫通孔が形成された位置には、上述したボルト34及びナット35が取り付けられている。但し、貫通孔の両端、少なくとも外装仕上げ部材33側の一端は、ボルト34及びナット35が取り付けられた後、モルタルやシーリング材等が充填され閉塞される。   As shown in FIG. 3, the composite panel 2 has a through-hole penetrating the fireproof member 31, the heat insulating member 32, and the exterior finish member 33 in the thickness direction, and the surface of the composite panel 2 on the exterior finish member 33 side. The bolt 34 is inserted into the through-hole and the nut 35 is tightened from the surface on the fireproof member 31 side, whereby the fireproof member 31, the heat insulating member 32, and the exterior finish member 33 are sandwiched between the head of the bolt 34 and the nut 35. It is integrated. In the composite panel 2, a plurality of the above-described through holes are formed at predetermined intervals in the in-plane direction of the composite panel 2 (a direction perpendicular to the thickness direction), and at the position where each through hole is formed, The bolt 34 and nut 35 described above are attached. However, at both ends of the through hole, at least one end on the exterior finishing member 33 side, a bolt 34 and a nut 35 are attached, and then mortar, a sealing material, etc. are filled and closed.

また、図3に示すように、複合パネル2の貫通孔のうち断熱部材32が位置する部分(断熱部材32に形成された貫通孔)には、断熱部材32が耐火部材31であるALCパネルと外装仕上げ部材33であるALCパネルとに挟み込まれて圧潰することを防止するため、耐火部材31と外装仕上げ部材33とに挟み込まれて圧縮力に対抗する圧潰防止具1が内挿されている。   Further, as shown in FIG. 3, in the through hole of the composite panel 2, in the portion where the heat insulating member 32 is located (through hole formed in the heat insulating member 32), the ALC panel in which the heat insulating member 32 is the fireproof member 31 and In order to prevent crushing by being sandwiched between the ALC panel which is the exterior finishing member 33, the crush prevention device 1 which is sandwiched between the fireproof member 31 and the exterior finishing member 33 and opposes the compressive force is inserted.

筒部11は、断熱部材32の厚みと略等しい軸方向長さを有しており、断熱部材32に形成された貫通孔に挿通されている。第1鍔部12は、断熱部材32と外装仕上げ部材33との間に延在している。第2鍔部13は、断熱部材32と耐火部材31との間に延在している。そして、上述したボルト34は、圧潰防止具1の連通孔17内を通過するように、複合パネル2の貫通孔に挿通されている。つまり、ボルト34は、筒部11内、第1鍔部12の開口12a、及び第2鍔部13の開口13aを通じて、2枚のパネルとしての耐火部材31及び外装仕上げ部材33と、断熱部材32とを厚み方向に貫通している。そして複合パネル2は、このボルト34にナット35を締め付けることにより一体化される。ボルト34に対してナット35を締め付けると、圧潰防止具1の筒部11が圧縮力に対抗するため、断熱部材32の圧潰が抑制される。また、筒部11の両端には第1鍔部12及び第2鍔部13が一体又は別体で固定されているため、外装仕上げ部材33及び耐火部材31からの圧縮力が筒部11の周方向全域に作用するように分散される。そのため、筒部11の周方向の一部のみに過大な圧縮力が作用することを抑制でき、筒部11の曲げ変形や座屈の発生を防ぐことができる。そのため、圧潰防止具1の近傍において、断熱部材32に局所的な潰れが生じることを抑制することができる。   The cylinder part 11 has an axial length substantially equal to the thickness of the heat insulating member 32, and is inserted through a through hole formed in the heat insulating member 32. The first flange 12 extends between the heat insulating member 32 and the exterior finishing member 33. The second flange 13 extends between the heat insulating member 32 and the refractory member 31. The bolt 34 described above is inserted into the through hole of the composite panel 2 so as to pass through the communication hole 17 of the crush prevention device 1. That is, the bolt 34 passes through the opening 11 a of the first flange portion 12 and the opening 13 a of the second flange portion 13 in the cylindrical portion 11, the fireproof member 31 and the exterior finishing member 33 as two panels, and the heat insulating member 32. And penetrates in the thickness direction. The composite panel 2 is integrated by tightening a nut 35 to the bolt 34. When the nut 35 is tightened with respect to the bolt 34, the cylindrical portion 11 of the crush prevention device 1 opposes the compressive force, so that crushing of the heat insulating member 32 is suppressed. In addition, since the first flange portion 12 and the second flange portion 13 are integrally or separately fixed at both ends of the cylindrical portion 11, the compressive force from the exterior finishing member 33 and the fireproof member 31 is Distributed to act across the direction. Therefore, it is possible to suppress an excessive compressive force from acting only on a part of the cylindrical portion 11 in the circumferential direction, and it is possible to prevent bending deformation and buckling of the cylindrical portion 11. Therefore, local crushing of the heat insulating member 32 in the vicinity of the crush prevention device 1 can be suppressed.

このように、ボルト34により複合パネル2を一体化する際に、圧潰防止具1の連通孔17を利用してボルト34を挿通させることで、複合パネル2の一体化作業の効率を向上させることができる。また、最も圧縮力が作用する位置に圧潰防止具1を配置するため、圧潰防止効果が高い。   Thus, when integrating the composite panel 2 with the bolt 34, the efficiency of the integration operation of the composite panel 2 is improved by inserting the bolt 34 using the communication hole 17 of the crush prevention device 1. Can do. Moreover, since the crush prevention tool 1 is arrange | positioned in the position where compressive force acts most, the crush prevention effect is high.

なお、筒部11は断熱部材32を厚み方向に貫通しているが、筒部11を、硬質の合成樹脂材料で形成すれば、中空構造と相まって、筒部11自体が屋内外間の熱移動の媒体(熱橋)にはなり難い。また、筒部11内に挿通されている接続部14についても、硬質の合成樹脂材料で形成すれば、中空構造と相まって、接続部14自体が屋内外間の熱移動の媒体(熱橋)にはなり難い。   In addition, although the cylinder part 11 has penetrated the heat insulation member 32 in the thickness direction, if the cylinder part 11 is formed with a hard synthetic resin material, coupled with the hollow structure, the cylinder part 11 itself is a heat transfer between the indoor and the outdoor. It is difficult to become a medium (heat bridge). In addition, if the connecting portion 14 inserted into the cylindrical portion 11 is also made of a hard synthetic resin material, the connecting portion 14 itself is used as a medium for heat transfer between indoors and outdoors (thermal bridge) when combined with the hollow structure. It ’s hard to be.

ここで、圧潰防止具1は、鍔部材22が装着されていない筒状部材21の筒部11先端を断熱部材32単体に形成された貫通孔に対して厚み方向の一方から他方に向かって挿通し、厚み方向の他方から筒部11先端に対して鍔部材22の接続部14を装着することにより、断熱部材32に対して取り付けられる。そして、圧潰防止具1が取り付けられた断熱部材32を、耐火部材31を構成するパネルと外装仕上げ部材33を構成するパネルとで挟み込み、ボルト34及びナット35により一体化し、複合パネル2を形成する。   Here, the crush prevention tool 1 inserts the front-end | tip part of the cylindrical part 21 of the cylindrical member 21 in which the collar member 22 is not mounted | worn from one side of the thickness direction with respect to the through-hole formed in the heat insulation member 32 single-piece | unit. And it attaches with respect to the heat insulation member 32 by mounting | wearing the connection part 14 of the collar member 22 with respect to the cylinder part 11 front-end | tip from the other of the thickness direction. Then, the heat insulating member 32 to which the crush prevention device 1 is attached is sandwiched between the panel constituting the fireproof member 31 and the panel constituting the exterior finishing member 33 and integrated by the bolt 34 and the nut 35 to form the composite panel 2. .

なお、筒部11の長さのみが異なる規格化された複数種の筒状部材21を用意し、断熱部材32の厚みに応じて使用する筒状部材21を適宜選択できるようにすることができる。このようにすれば、断熱部材32の厚みによらず鍔部材22を1つの規格に統一でき、製造コストを抑えることができる。また、図4、図5に示すように、圧潰防止具50を、筒部11を構成する筒状部材51と、この筒状部材51に対して着脱可能に装着され、第1鍔部12を構成する第1鍔部材52と、筒状部材51に対して着脱可能に装着され、第2鍔部13を構成する第2鍔部材53と、により構成することも可能である。このような構成とすれば、筒状部材51の構成をより単純化でき、第1鍔部材52及び第2鍔部材53を共通の構成とすることができるため、製造コストをより抑えることが可能である。   Note that a plurality of types of standardized cylindrical members 21 that differ only in the length of the cylindrical portion 11 are prepared, and the cylindrical member 21 to be used can be appropriately selected according to the thickness of the heat insulating member 32. . If it does in this way, regardless of the thickness of the heat insulation member 32, the eaves member 22 can be unified into one standard, and manufacturing cost can be held down. Also, as shown in FIGS. 4 and 5, the crush prevention device 50 is detachably attached to the tubular member 51 constituting the tubular portion 11 and the tubular member 51, and the first flange portion 12 is attached to the tubular member 51. It can also be configured by a first collar member 52 that is configured and a second collar member 53 that is detachably attached to the tubular member 51 and that constitutes the second collar portion 13. With such a configuration, the configuration of the cylindrical member 51 can be further simplified, and the first flange member 52 and the second flange member 53 can be configured in common, so that the manufacturing cost can be further suppressed. It is.

図4に示す圧潰防止具50の筒状部材51、第1鍔部材52及び第2鍔部材53の相互間の取り付け構成は、上述した圧潰防止具1の筒状部材21及び鍔部材22の相互間の取り付け構成と同様、筒状の接続部14を筒部11内に嵌合保持させるものであるため、ここでは説明は省略する。また、図5に示す圧潰防止具50を備える複合パネル60についても、圧潰防止具50の構成以外は、上述した複合パネル2と同様であるため、ここでは説明を省略する。   The attachment structure among the cylindrical member 51, the first flange member 52, and the second flange member 53 of the crush prevention device 50 shown in FIG. 4 is the same as that of the tubular member 21 and the flange member 22 of the above-described crush prevention device 1. Since the cylindrical connecting portion 14 is fitted and held in the cylindrical portion 11 as in the case of the mounting configuration therebetween, the description thereof is omitted here. Further, the composite panel 60 provided with the anti-crush device 50 shown in FIG. 5 is the same as the above-described composite panel 2 except for the configuration of the anti-collapse device 50, and thus the description thereof is omitted here.

更に、図6は、圧潰防止具1の筒状部材21及び鍔部材22の接続構成の変形例を示す図である。図6に示すように、筒状部材21の筒部11は雌ねじ部71を備えている。また、接続部14は雌ねじ部71と螺合する雄ねじ部72を備えている。接続部14は、雄ねじ部72が雌ねじ部71と螺合することにより、筒部11に対して着脱可能に装着される。このような構成とすれば、筒部11に対して接続部14を回動させる、つまり、ねじ接合を締め付ける方向又は緩める方向に回動させることにより、第1鍔部12(図1参照)と第2鍔部13との対向距離を変動することができる。これにより、使用する断熱部材32(図2参照)の厚さに合わせて第1鍔部12と第2鍔部13との対向距離を調整することができ、1つの圧潰防止具1により対応できる断熱部材32の厚みの範囲を拡げることができる。   Further, FIG. 6 is a view showing a modification of the connection configuration of the cylindrical member 21 and the flange member 22 of the crush prevention device 1. As shown in FIG. 6, the tubular portion 11 of the tubular member 21 includes a female screw portion 71. The connecting portion 14 includes a male screw portion 72 that is screwed with the female screw portion 71. The connection portion 14 is detachably attached to the tube portion 11 by the male screw portion 72 and the female screw portion 71 being screwed together. With such a configuration, the connecting portion 14 is rotated with respect to the cylindrical portion 11, that is, by rotating in the direction in which the screw joint is tightened or loosened, the first flange portion 12 (see FIG. 1) and The facing distance to the second flange 13 can be changed. Thereby, the opposing distance of the 1st collar part 12 and the 2nd collar part 13 can be adjusted according to the thickness of the heat insulation member 32 (refer FIG. 2) to be used, and it can respond with one crush prevention tool 1. FIG. The range of the thickness of the heat insulating member 32 can be expanded.
