Description
本發明係關於一種分隔用板、分隔壁及房間構造。 The present invention relates to a partition board, partition wall and room structure.
先前,於建築物中,針對每特定之面積(面積劃分),或者於倉庫與理貨室之交界等用途不同之房間之交界(異種用途劃分)設置有防火劃分區域,以謀求防止火災時之內部延燒。關於構成建築物之壁中構成防火劃分壁之分隔壁,根據建築基準法需要1小時之耐火性能。 Previously, in buildings, fire protection divisions were set up for each specific area (division of area), or at the junction of rooms with different uses (division of different uses) such as the junction of warehouses and tally rooms, in order to prevent fire hazards. Burning inside. As for the partition wall constituting the fire partition wall among the walls constituting the building, fire resistance performance of 1 hour is required according to the Building Standard Act.
且說,根據近來之物流需要之擴大,而冷凍冷藏倉庫趨於大型化,該等建築物亦成為防火劃分之對象,故而需要藉由分隔壁而劃分。然而,兼具耐火性、隔熱性,而且進而該分隔壁因自具有耐火性之地板連續至具有耐火性之屋頂而必須為長條,此情況亦使得材料選定越發困難。因此,先前暫時利用具有耐火性之輕量氣泡混凝土等分隔壁劃分,而且於該壁之兩側分別使用金屬夾層板等隔熱板構成成為冷凍冷藏倉庫之房間。 In addition, according to the recent expansion of logistics needs, and the refrigerated warehouses tend to be large-scale, these buildings have also become the object of fire protection division, so they need to be divided by partition walls. However, it has both fire resistance and heat insulation, and furthermore, the partition wall must be long because it continues from the fire-resistant floor to the fire-resistant roof. This situation also makes the selection of materials more difficult. Therefore, partition walls such as refractory lightweight cellular concrete have been used for the time being, and insulation panels such as metal sandwich panels are used on both sides of the wall to form a room for refrigerated warehouses.
然而,於該情形時,隔熱板與成為防火劃分區域之分隔壁之間成為空調溫度不同之空間,故而存在如下問題:容易於隔熱板之表面產生冷凝,進而由於該等之空間狹窄難以清掃,故而容易產生黴或蟲害。因此, 為了抑制此種危害,要求兼具耐火性與較高之隔熱性,進而能夠以長條使用之分隔壁。 However, in this case, the air-conditioning temperature is different between the heat insulation board and the partition wall serving as the fire compartment, so there is a problem that condensation is likely to occur on the surface of the heat insulation board, and it is difficult to Cleaning, so prone to mildew or insect damage. therefore, In order to suppress such hazards, a partition wall that has both fire resistance and high heat insulation and can be used in a long strip is required.
先前,作為建築用板,提出有將包括岩絨(rock wool)之芯材利用金屬板夾著並接著而成者(例如,參照專利文獻1)。然而,將岩絨設為芯材之建築用板雖然具有較高之耐火性,但是作為冷凍冷藏倉庫之分隔壁則隔熱性能不充分。 Conventionally, as a building board, a core material including rock wool (rock wool) is sandwiched between metal plates and then bonded (for example, refer to Patent Document 1). However, although the building board using rockwool as a core material has high fire resistance, it has insufficient heat insulation performance as a partition wall of a refrigerated warehouse.
為了使將岩絨設為芯材之分隔壁用作冷凍冷藏倉庫,不僅就岩絨所具有之隔熱性而言,壁厚成為極厚者,而且岩絨之水蒸氣或氣體之透過性較高,進而具有較大之吸濕性與吸水性。因此,容易產生內部冷凝,暫時進入至壁體內之水蒸氣或水分於壁體內自由地移動,受害較大進而難以修復。 In order to make the partition wall with rock wool as the core material used as a refrigerated warehouse, not only in terms of the thermal insulation of rock wool, the wall thickness becomes extremely thick, but also the water vapor or gas permeability of rock wool is relatively low. High, which in turn has greater hygroscopicity and water absorption. Therefore, internal condensation is easy to occur, and the water vapor or moisture temporarily entered into the wall moves freely in the wall, causing great damage and difficult to repair.
又,於專利文獻2中,提出有將包括添加有無機材之酚樹脂發泡體之芯材利用包括金屬材之正面材與背面材夾入而成之耐火板。然而,耐火板之耐火性於用作分隔壁時依然不充分,又,構造上難以用作長條之分隔壁。
In addition,
因此,於專利文獻3中,提出有於包括金屬材之正面材與背面材之間積層接著有機隔熱板層及無機板層而成之隔熱耐火夾層板。
Therefore, in

然而,即便根據專利文獻3中所記載之隔熱耐火夾層板,作為分隔壁之耐火性亦依然不充分,成為無法滿足上述1小時耐火性能之問題。
However, even according to the heat-insulating fire-resistant sandwich panel described in
因此,本發明之目的在於提供一種兼備較高之耐火性與隔熱性之分隔用板、進而將其長條地使用之房間構造。 Therefore, an object of the present invention is to provide a partition board having high fire resistance and heat insulation performance, and furthermore, provide a room structure in which it is used in a long strip.

以下,參照圖式對本發明之實施形態進行說明。圖1A表示本發明之分隔用板之一例之整體圖,圖1B表示寬度方向剖視圖之一部分。圖1A所示之分隔用板1之特徵在於具有:正面材11及背面材12,其等包括金屬
材;以及2片有機隔熱板層13、14及夾於該等2片有機隔熱板層13、14之間的無機板層15,其等配置於正面材11與背面材12之間。此處,上述2片有機隔熱板層之一者13與正面材11、及上述2片有機隔熱板層之另一者14與背面材12分別藉由有機系接著劑而接著,構成上述2片有機隔熱板層13、14之各者之樹脂包括熱硬化性樹脂。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1A shows an overall view of an example of a partition plate of the present invention, and FIG. 1B shows a part of a cross-sectional view in the width direction. The feature of the
於本實施形態中,如圖1B所示,正面材11及背面材12係其等之周緣部朝有機隔熱板層13、14側彎折。而且,彎折部(第一彎折部)11a、12a以卡合於設置在有機隔熱板層13、14之周緣部之凹部13a、14a之方式構成。於正面材11(背面材12)與有機隔熱板層13(14)之間,形成有包括有機系接著劑之接著劑層16(17),有機系接著劑之一部分進入至第一彎折部11a(12a)與有機隔熱板層13、14之間,提高正面材11(背面材12)與有機隔熱板層13(14)之一體性。
In this embodiment, as shown in FIG. 1B , the peripheral edges of the
正面材11及背面材12係以於加熱時自有機隔熱板層13、14剝離且向加熱側大幅度膨脹而變形之方式構成。正面材11及背面材12包括金屬材,可使用將金屬材藉由加壓成形、擠出成形、輥壓成形等而形成為特定之剖面形狀者。作為金屬材,例如,可使用熔融55%鋁-鋅鍍覆鋼板、熔融鋅鍍覆鋼板、塗裝熔融55%鋁-鋅鍍覆鋼板(塗裝:聚酯系樹脂、丙烯酸系樹脂、矽系樹脂、胺基醇酸系樹脂、氯乙烯系樹脂、氟系樹脂、環氧系樹脂、胺基甲酸酯系樹脂)、塗裝熔融鋅鍍覆鋼板(塗裝:聚酯系樹脂、丙烯酸系樹脂、矽系樹脂、胺基醇酸系樹脂、氯乙烯系樹脂、氟系樹脂、環氧
系樹脂、胺基甲酸酯系樹脂)、塗裝不鏽鋼鋼板(塗裝:聚酯系樹脂、丙烯酸系樹脂、矽系樹脂、胺基醇酸系樹脂、氯乙烯系樹脂、氟系樹脂、環氧系樹脂、胺基甲酸酯系樹脂)、覆氯乙烯樹脂膜/金屬板、高耐候性軋壓鋼材(塗裝:環氧系樹脂、胺基甲酸酯系樹脂)、雙面聚酯樹脂系塗裝/熔融鋁鍍覆鋼板、鐵氧體系不鏽鋼鋼板、雙面丙烯酸樹脂系塗裝/鋅合金板等。再者,一般而言,上述金屬板之塗裝不僅於表面實施,而且亦於與有機隔熱板接著之面實施,於該情形時,自接著劑之常溫時之接著性與加熱時之初期之燃燒性之方面而言選擇樹脂,較佳為使用聚酯樹脂、胺基甲酸酯樹脂及丙烯酸樹脂等。
The
正面材11及背面材12之尺寸可根據設計而適當地設定,例如,可設為長度為0.6~12m,寬度為300~1000mm。又,正面材11及背面材12之厚度自強度或重量、經濟性之方面而言,可設為0.3~1.6mm,但更佳為0.4~1.0mm。
The size of the
有機隔熱板層13、14為用以使分隔壁具有隔熱性之層,有機隔熱板層13、14只要為使無機板層15變厚且不使背面側之有機隔熱板層14之溫度上升且進而耐熱性較高者,則材料並不限定。作為構成此種有機隔熱板層之樹脂,可使用聚醯亞胺發泡體或PET(polyethylene terephthalate,聚對苯二甲酸乙二酯)樹脂發泡體等。但是,於使無機板層15極力變薄而謀求輕量化之情形時,自加熱側之無機板層15之被覆效果、非加熱側有機隔熱板層14之耐熱性之方面而言,作為有機隔熱板層13、14,較佳為使用
構成之樹脂包括熱硬化性樹脂之有機隔熱板層。藉此,於將正面材11(背面材12)加熱時,於將正面材11(背面材12)與有機隔熱板層13(14)剝離之後,可將有機隔熱板層13(14)留在無機板層15之表面。
The organic heat insulating board layers 13 and 14 are layers used to make the partition wall have heat insulation properties. The organic heat insulating board layers 13 and 14 only need to thicken the
再者,於圖1A及圖1B中,使有機隔熱板層由2片構成,且於其等之間夾有無機板層15,但有機隔熱板層可由3片以上構成。例如,可使有機隔熱板層由4片構成,於第2片與第3片之間夾入無機板層15。
Furthermore, in FIG. 1A and FIG. 1B , the organic heat insulating board layer is composed of two sheets, and the
作為上述熱硬化性樹脂,可使用聚胺基甲酸酯樹脂、異氰脲酸酯樹脂、酚樹脂等。其中,由於具有較高之難燃性,作為熱硬化性樹脂較佳為使用酚樹脂,進而,更佳為選擇於加熱碳化時具有膨脹性者。 As said thermosetting resin, polyurethane resin, isocyanurate resin, phenol resin, etc. can be used. Among them, it is preferable to use a phenolic resin as a thermosetting resin because of its high flame retardancy, and it is more preferable to select a phenolic resin that has expandability during heating and carbonization.
有機隔熱板層13、14可使用將熱硬化性樹脂或硬化劑、發泡劑等一起混合後發泡並硬化,將所獲得之樹脂發泡體製成板狀者。又,有機隔熱板層13、14自成形上之方便性或與正面材11(背面材12)或無機板層15之接著性等之方面而言,亦可使用於正面背面具有面材者。
The organic heat insulating board layers 13 and 14 can be formed by mixing a thermosetting resin, a curing agent, a foaming agent, etc., foaming and hardening, and forming the obtained resin foam into a plate shape. In addition, the organic heat-insulating board layers 13 and 14 can also be used in those with front and back face materials in terms of the convenience of forming or the adhesion with the front material 11 (back material 12) or the
具有此種樹脂發泡體及面材之有機隔熱板層13、14可於使將熱硬化性樹脂、硬化劑、發泡劑等混合於面材上而成之混合物對以固定速度移行之面材上噴出混合物之後,於硬化爐內之輸送帶間成形為板狀而形成。又,有機隔熱板層13、14亦可藉由預先將正面材11、背面材12及無機板層15以特定間隔之間隙設置之後,對該間隙注入有機樹脂材料之方法來構
成。於該情形時,若適當地選定上述有機樹脂材料,則可藉由其自接著力而兼用接著劑。
The organic heat insulation board layers 13 and 14 with such resin foam and surface material can move at a fixed speed when the mixture of thermosetting resin, hardener, foaming agent, etc. is mixed on the surface material. After the mixture is sprayed on the surface material, it is formed into a plate shape between the conveyor belts in the curing furnace. In addition, the organic heat-insulating board layers 13, 14 can also be constructed by pre-setting the
作為上述面材,可使用聚酯不織布、聚丙烯不織布、鋁箔、不燃性之加工紙、及將該等材料組合而成者等。於介隔該面材而將有機隔熱板層13、14接著於無機板層15之情形時,關鍵在於,在耐火試驗時不讓有機隔熱板層13、14自無機板層15之表面長時間脫落。因此,使用不燃性之面材或耐熱性接著劑於耐火性能上最有利,但由於其等均價格高昂,故而亦可於不損及耐火性之範圍使用有機系之面材。又,針對在耐火試驗時自無機板層15產生之水蒸氣集聚於面材與無機板層15之間時產生之接著剝離等之對策亦較為重要,亦以使用具有透濕性之面材為佳。自該等之方面而言,有機系之面材之中聚酯不織布具有綜合價格、耐熱性、透濕性之性能,而較佳。
As the surface material, polyester nonwoven fabric, polypropylene nonwoven fabric, aluminum foil, non-combustible processed paper, or a combination of these materials can be used. When the organic heat-insulating board layers 13 and 14 are attached to the
有機隔熱板層13、14之尺寸可根據分隔用板1之設計而適當地設定。有機隔熱板層13、14如圖2A所示,可於長度方向將複數片有機隔熱板13b(14b)排列而構成,關於超過板1之長度之量可切斷而使長度對齊。又,有機隔熱板層13、14可於寬度方向將複數片有機隔熱板13b(14b)排列而構成,關於超過板1之寬度之量可切斷而使寬度對齊。如此,有機隔熱板層13、14可包括於其面內方向相鄰之複數片有機隔熱板13b(14b)。
The dimensions of the organic heat insulation board layers 13 and 14 can be appropriately set according to the design of the
該等相鄰之有機隔熱板13b(14b)之切口間亦可接著,但尤其於使用碳化時具有膨脹之特性之樹脂之情形時即便省略亦不會降低耐火性,只要
以作為板之彎曲強度、剪切強度及製造上之方便性決定即可。又,亦可於相鄰之有機隔熱板13b(14b)之切口間設置間隙而配置。於該情形時,於將有機隔熱板13b(14b)與正面材11(背面材12)使用有機系接著劑來接著時若將正面材11與背面材12加壓,則有機系接著劑進入至上述間隙,相鄰之有機隔熱板13b(14b)被牢固地固定,可提高板1之強度性能。於有機隔熱板13b(14b)較薄之情形時,可獲得與於切口整個面塗佈接著劑進行接著變化不大之強度。
The cuts of the adjacent
再者,於有機隔熱板13b(14b)包括上述樹脂發泡體與面材,將相鄰之有機隔熱板13b(14b)之切口間接著之情形時,於切口面塗佈接著劑並將有機隔熱板13b(14b)彼此壓抵。此時,樹脂發泡體部分具有彈性故而被壓縮,相對於此,面材不具有彈性,故而切口面附近之面材變得成為剩餘,切口面之密接性降低而有機隔熱板13b(14b)間之接著性降低。
Furthermore, when the organic
因此,如圖2B所示,較佳為將有機隔熱板13b(14b)之切口面附近之角部去除。藉此,由於將切口面附近之面材13c去除,故而於將相鄰之有機隔熱板13b(14b)彼此壓抵時,切口面附近之面材13c並無剩餘,進而形成在將切口面彼此壓抵時多餘且集中於切口面之下方之接著劑之積存部,藉此可提高切口面之密接性。如此一來,可提高有機隔熱板13b(14b)間之接著強度。上述角部之去除之剖面範圍係考慮接著劑之塗佈量、黏性及壓抵切口面之壓力等而適當設定,但一般而言只要對半徑為1mm~5mm之1/4圓狀或1邊為1mm~5mm之三角形狀之部分進行即可。進而,一般而言於長度方向遍及全長而設置,但較佳為將邊之端部等容易積存接著劑之
部分大幅度去除。
Therefore, as shown in FIG. 2B , it is preferable to remove the corners near the notch surface of the
再者,如上所述,由於樹脂發泡體13d具有彈性,故而可藉由有機隔熱板13b(14b)彼此之壓抵,吸收由切口面本身之平坦度或上述角部之去除所致之尺寸之誤差。
Moreover, as mentioned above, since the
又,自隔熱性或強度、經濟性之方面而言,有機隔熱板層13、14之厚度設為20~150mm,更佳為設為30~100mm,密度設為20~80,更佳為設為25~50kg/m3。 Also, from the aspects of heat insulation, strength, and economy, the thickness of the organic heat insulation board layers 13 and 14 is set to 20-150mm, more preferably 30-100mm, and the density is set to 20-80, more preferably It is set to 25~50kg/m 3 .
於本發明中,關鍵在於正面材11(背面材12)與有機隔熱板層13(14)藉由有機系接著劑而接著。藉此,於將正面材11(背面材12)加熱時,在250~400℃左右,有機系接著劑燃燒而失去接著性,可使正面材11(背面材12)與有機隔熱板層13(14)良好地剝離。其結果,有機隔熱性板層13、14、無機板層15及背面材12不會追隨正面材11之變形,防止於其等產生較大之變形、龜裂或者產生材料間或材料內部之剝離,可維持該等材料之一體性與平面性,發揮耐火性。
In the present invention, the key point is that the front material 11 (back material 12) and the organic heat insulating board layer 13 (14) are bonded by an organic adhesive. In this way, when the front material 11 (back material 12) is heated, at about 250-400°C, the organic adhesive burns and loses its adhesiveness, so that the front material 11 (back material 12) and the organic heat insulation board layer 13 (14) Good peeling. As a result, the organic
有機系接著劑只要為正面材11(背面材12)於加熱初期燃燒而失去作為接著劑之功能者,則並不特別限定。作為此種有機系接著劑,可使用胺基甲酸酯樹脂系(主成分:胺基甲酸酯樹脂,溶劑:酯類、酮類)、環氧樹脂系(主成分:(主劑)環氧樹脂、(硬化劑)改性聚胺、改性聚硫醇,溶劑:酯 類、酮類、醇類)、乙酸乙烯酯樹脂系(主成分:乙酸乙烯酯樹脂,溶劑:醇類、酯類、酮類)、改性矽系者。其中,自適合於低溫下之使用之方面而言,較佳為使用胺基甲酸酯樹脂系或環氧樹脂系者作為有機系接著劑。 The organic adhesive is not particularly limited as long as it burns at the initial stage of heating and loses its function as an adhesive. As such organic adhesives, urethane resins (main component: urethane resin, solvents: esters, ketones), epoxy resins (main component: (main agent) cyclo Oxygen resin, (hardener) modified polyamine, modified polythiol, solvent: ester Classes, ketones, alcohols), vinyl acetate resins (main component: vinyl acetate resin, solvent: alcohols, esters, ketones), modified silicones. Among them, it is preferable to use a urethane resin-based or an epoxy resin-based adhesive as an organic adhesive from the viewpoint of being suitable for use at low temperatures.
無機板層15係為了發揮作為板之耐火性重要之層,可包括輕量氣泡混凝土、石膏板、矽酸鈣板等。其中,無機板層15較佳為包括輕量氣泡混凝土。作為輕量氣泡混凝土,較佳為高溫高壓養護且利用對內部實施特殊防銹處理之鋼筋墊子或金屬格網(metal lath)(鋼製之金屬網)補強之比重0.5左右者,比重0.35左右者隔熱性及輕量性進而優異而較佳。又,輕量氣泡混凝土自其製造方法之特徵而言可於內部容易地配置金屬格網或鋼筋墊子。
The
於無機板層15包括石膏板或矽酸鈣板之情形時,該等材料結晶水較多,先前多用於防耐火之用途,但結晶水釋放之後翹曲或龜裂大量地產生,故而必須使厚度變大,或者於內部裝填不燃性之補強材。於目前之成型方法中難以於內部裝填補強材,故而必須使用重疊複數片並夾於其間等方法。上述石膏板、矽酸鈣板之接著亦可使用有機系接著劑,但若使用將水玻璃或膠體二氧化矽等作為黏合劑、將氧化鋁等氧化物作為填料之無機系接著劑,則於加熱時間中或加熱結束後均可長時間維持接著性,故而較佳。
In the case where the
又,作為上述不燃性之補強材,可使用玻璃纖維網或金屬格網等。 In addition, as the above-mentioned incombustible reinforcing material, a glass fiber mesh, a metal mesh, or the like can be used.
無機板層15之尺寸可根據分隔用板1之設計而適當地設定。無機板層15如圖2C所示,可於長度方向將複數片無機板15a排列而構成,關於超過板1之長度之量可切斷而使長度對齊。又,無機板層15可於寬度方向將複數片無機板15a排列而構成,關於超過板1之寬度之量可切斷而使寬度對齊。如此,無機板層15可包括於其面內方向相鄰之複數片無機板15a。
The size of the
再者,圖2C所示之構成無機板層15之複數片無機板15a以縱接縫錯開之方式配置,但亦可以縱接縫排列成一直線之方式配置。
Moreover, the plurality of
於無機板層15包括複數片無機板15a之情形時,較佳為,將複數片無機板15a之切口面相互藉由耐火接著劑而接著,或於複數片無機板15a之切口面間裝填熱膨脹性片材,或將複數片無機板15a藉由連結金屬件而相對於面外方向、面內方向、或面外方向及面內方向之移動相互固定,或一併使用該等方法。
In the case where the
作為耐火接著劑,可使用以矽酸鈉為主成分,添加氧化矽、高嶺土、滑石、黏土礦物等無機成分而成者,或進而添加苯乙烯-丁二烯共聚物等有機系之添加劑來改善作業性者。另外,亦可使用對水泥系材料適當添加黏合劑而成者。 As a refractory adhesive, sodium silicate can be used as the main component, and inorganic components such as silicon oxide, kaolin, talc, and clay minerals can be added, or organic additives such as styrene-butadiene copolymer can be added to improve Workers. Moreover, what added the binder suitably to the cement type material can also be used.
又,作為熱膨脹性片材,可將成形為包含一半左右以上無機材料之片狀者加工為特定尺寸來使用,該無機材料於150~200℃左右開始膨 脹,於300℃膨脹為5~15倍左右,於600℃膨脹為10~30倍左右,於作為加熱溫度之900℃左右亦不消失。作為組成,例如可使用對形成膨脹層之硼酸等無機填充材添加作為膨脹材之膨脹石墨,進而添加礦物油、碳黑等添加劑與丁基橡膠等黏合劑,成形為片狀者等。又,於使用硼酸作為無機填充材之情形時,相對於硼酸添加以重量比計0.45以上1.5以下之氧化鋁,且使矽酸化合物、鎂鹽及鈣鹽之合計含量相對於硼酸以重量比計未達10%,藉此,可提高膨脹後之熱膨脹性片材之形狀保持能力,故而較佳。 In addition, as a heat-expandable sheet, it can be used by processing a sheet shape containing more than half of the inorganic material into a specific size, and the inorganic material begins to expand at about 150~200°C. It expands about 5-15 times at 300°C, 10-30 times at 600°C, and does not disappear at about 900°C as the heating temperature. As a composition, for example, an inorganic filler such as boric acid that forms the expansion layer is added with expanded graphite as an expansion material, further additives such as mineral oil and carbon black, and a binder such as butyl rubber are added to form a sheet. Also, when boric acid is used as the inorganic filler, alumina is added in a weight ratio of 0.45 to 1.5 relative to boric acid, and the total content of the silicic acid compound, magnesium salt, and calcium salt is calculated in a weight ratio relative to boric acid. If it is less than 10%, it is preferable because the shape retention ability of the expanded thermally expandable sheet can be improved.
於在2片有機隔熱板層13、14之間配置無機板層15時,如圖2D所示,較佳為,有機隔熱板層13、14中之橫接縫及無機板層15中之橫接縫於長度方向錯開。藉此,可提高分隔用板1之強度。該錯開較佳為設為有機隔熱板層13、14之厚度之1~3倍左右。又,自耐火性或隔熱性之方面而言,亦較佳為設置相同程度之錯開。
When the
關於無機板層15與有機隔熱板層13、14之接著,關鍵在於以使於耐火試驗時碳化之有機隔熱板儘量不脫落之方式選擇材料。藉由使用無機系接著劑,而耐火性提高,但作為板1之製作需要工夫。於使用有機系接著劑之情形時,考慮於耐火試驗時無機板之加熱側表面溫度於無機板層15之結晶水蒸發之期間長時間止於100℃,必須選擇至少於100℃維持充分之接著力,進而不因噴出之水蒸氣而導致接著力降低之材料。作為具有此種性質之材料,較佳為使用胺基甲酸酯樹脂、環氧樹脂等。又,若使用與正面材11(背面材12)及有機隔熱板層13(14)之接著劑相同者,則製作效率優異,故而較佳。
Regarding the bonding of the
又,接著劑之塗佈量較佳為大概每一層100~500g/m2,根據各接著劑層之母材之種類、表面之平坦度、塗佈後之加壓之壓力、時間及作為分隔用板之目標性能來決定。 In addition, the coating amount of the adhesive is preferably approximately 100~500g/m 2 per layer, depending on the type of base material of each adhesive layer, the flatness of the surface, the pressure and time of pressing after coating, and as a partition Determined by the target performance of the board.
於作為分隔用板1追求較大之彎曲負載之情形時,必須藉由各接著劑層牢固地接著直至產生母材破壞為止,作為接著劑之塗佈量,正面材11(背面材12)與有機隔熱板層13(14)之間較佳為100~300g/m2左右,有機隔熱板層13、14相互間較佳為100~300g/m2左右,有機隔熱板層13(14)與無機板層15之間較佳為200~500g/m2左右。
In the case of pursuing a large bending load as the
若正面材11(背面材12)與有機隔熱板層13(14)之間之塗佈量過多,則要考慮直至於火災時加熱之情形時剝離為止之期間之時間,如此較佳為100~500g/m2。較佳為,各層均藉由加壓而接著劑於整體均勻地擴散,根據接著劑之黏度與接著材料之平坦度、接著劑之易擴散度,來決定接著劑之塗佈量與加壓壓力。若有機隔熱板層13(14)相互間及有機隔熱板層13(14)與無機板層15之間塗佈量過多,則從自加壓時之樓層間之接著劑漏出防止(外觀)之觀點而言較佳為100~500g/m2。
If the amount of coating between the front material 11 (back material 12) and the organic heat-insulating board layer 13 (14) is too much, then the time until the period during the peeling in the case of heating during a fire will be considered, so it is preferably 100 ~500g/m 2 . Preferably, the adhesive spreads evenly throughout the entire layer by applying pressure. The amount of adhesive applied and the pressure applied are determined according to the viscosity of the adhesive, the flatness of the adhesive material, and the ease of spreading of the adhesive. . If the amount of coating between the organic heat-insulating board layers 13 (14) and between the organic heat-insulating board layers 13 (14) and the
再者,於使用接著劑來使無機板層15與有機隔熱板層13、14接著時,較佳為於塗佈接著劑之前,於無機板層15之表面預先塗佈底塗劑。藉此,使底塗劑含浸於無機板層15,可提高無機板層15與有機隔熱板層13、14之接著強度。
Furthermore, when using an adhesive to bond the
藉由塗佈底塗劑,不僅即便將接著劑之塗佈量減少相應量亦可獲得同等之接著強度,而且可省去無機板層15之表面之粉塵等之清掃之工夫,或不易受到無機板層15之含水狀態之影響,或減小接著強度之不均。進而,亦可壓縮與接著相關之材料費整體。
By applying the primer, not only the same adhesive strength can be obtained even if the coating amount of the adhesive is reduced by a corresponding amount, but also the work of cleaning the dust on the surface of the
作為上述底塗劑,藉由使用環氧系、胺基甲酸酯系及酚系等熱硬化性樹脂,可提高耐熱性。另一方面,丙烯酸系之底塗劑為熱塑性,但耐熱性相對良好,作業性或價格方面特別優異,故而亦可將該等性能綜合地考慮而使用。 Heat resistance can be improved by using a thermosetting resin, such as an epoxy type, a urethane type, and a phenol type, as said primer. On the other hand, acrylic primers are thermoplastic, but they have relatively good heat resistance and are particularly excellent in terms of workability and price, so they can also be used in consideration of these properties.
又,於無機板層15之厚度相對較小之情形時,若如上所述使用接著劑來將無機板層15與有機隔熱板層13、14接著,則有無法在因火災等而置於高溫環境時維持接著之虞。於此種情形時,若將非加熱側之有機隔熱板層14與無機板層15機械固定,則於非加熱側之有機隔熱板層14與無機板層15之接著斷開之後,無機板層15亦不會馬上脫落而可維持耐火性。再者,於上述說明中將有機隔熱板層13設為加熱側,但於火災在分隔壁之相反側產生之情形時加熱側成為非加熱側,故而必須將有機隔熱板層13與無機板層15亦機械固定。
Also, when the thickness of the
具體而言,可使用如圖3A所示之錨定材A或如圖3B所示之螺釘V等,將有機隔熱板層13、14與無機板層15機械固定。藉此,可在置於高溫環境時維持非加熱側之有機耐火性。
Specifically, the organic thermal insulation board layers 13, 14 and the
作為錨定材A,可使用前端擴張型之錨定件或前端擴張型之釘。其等為用以將無機板層15固定於有機隔熱板層13(14)者。無機板層15堆疊,其自重傳遞至下段,最終經由下部接縫材傳遞至樓板(floor slab),故而只要有一體化所需之拉拔耐力即可,但為了安全,若可將一片一片之無機板層15之自重利用各錨定材A負擔,則更佳。為了確保拉拔耐力,重要的是錨定材A之頭部之與軸向正交之剖面之面積,但為了支持作用於鉛直方向之自重,重要的是錨定材A之軸向剖面與有機隔熱板層13(14)接觸之面積。於該情形時,較佳為使用軸部為直徑5~8Φ左右者。
As the anchor material A, a front-expanded anchor or a front-expanded nail can be used. These are used to fix the
又,於螺釘V之情形時,亦只要與上述錨定材A同樣地考慮即可,但若配置於有機隔熱板層13(14)之部分不設置螺絲而保持線狀,則用以負擔鉛直方向之負載之接觸狀態更佳。又,螺釘V之頭部之形狀亦較佳為不僅使與軸向正交之面積變大,而且設為盤頭或鍋形狀,使軸向之剖面面積變大。 In addition, in the case of the screw V, it is enough to consider the same as the above-mentioned anchor material A, but if the part arranged on the organic heat insulation board layer 13 (14) does not provide a screw and maintains a linear shape, it will be used as a burden. The contact state of the load in the vertical direction is better. Also, it is preferable that the shape of the head of the screw V not only enlarges the area perpendicular to the axial direction, but also has a pan head or pot shape to enlarge the cross-sectional area in the axial direction.
進而,於使用表面帶有不織布等面材者作為有機隔熱板層13(14)之情形時,若以極力保留面材之狀態裝設螺釘V,則不僅拉拔方向之頭部陷落強度提高,而且鉛直方向之耐力亦提高,故而較佳。 Furthermore, when using surface materials such as non-woven fabrics on the surface as the organic heat insulation board layer 13 (14), if the screw V is installed in a state where the surface material is kept as much as possible, not only the head collapse strength in the pulling direction is improved , and the endurance in the vertical direction is also improved, so it is better.
如圖3A及圖3B所示,於有機隔熱板層13(14)具有雙層構造之情形時,即,於將有機隔熱板層13(14)於無機板層15之單側以2片重疊使用之情形時,較佳為無機板層15側之有機隔熱板層13(14)之背面側之表面使用
頭部之背面側形狀為平坦之鍋形狀者。
As shown in Fig. 3A and Fig. 3B, when the organic heat insulation board layer 13 (14) has a double-layer structure, that is, when the organic heat insulation board layer 13 (14) is placed on one side of the
另一方面,如圖3C所示,於有機隔熱板層13(14)具有單層構造之情形時,即,於將有機隔熱板層13(14)於無機板層15之單側僅使用1片之情形時,必須以不與背面材12接觸之方式使頭部整體稍微下沉,但於該情形時,若螺釘V作為盤頭連同面材一起下沉,則更佳。再者,於圖3C中,於無機板層15之切口面間填充有熱膨脹性片材21。
On the other hand, as shown in FIG. 3C, when the organic heat insulating board layer 13 (14) has a single-layer structure, that is, when the organic heat insulating board layer 13 (14) is placed on one side of the
又,尤其於僅使用1片有機隔熱板層13(14)之情形時,於使螺釘頭沉入並施工之情形時,若螺釘頭與背面材12藉由接著劑而接著,則不易產生螺釘頭之鉛直方向之偏移或旋轉,鉛直方向之耐力提高。於該情形時,螺釘頭設為1~5mm左右之沉入於將背面材12與有機隔熱板層14利用接著劑貼合之情形時,接著劑易於蔓延,故而較佳。然而,藉由背面材12與有機隔熱板層14之貼合時之加壓,而於有機隔熱板層14產生由加壓壓力所致之變形,故而較佳為考慮該量來決定使螺釘頭沉入之量。
In addition, especially when only one organic heat insulation board layer 13 (14) is used, when the screw head is sunk and constructed, if the screw head and the
又,於螺釘頭過多地沉入之情形時,於將背面材12接著於有機隔熱板層14之前,可對螺釘頭下沉之部分預先填充接著劑。又,萬一於背面材12與螺釘頭之接著剝離時,亦為了作為剪切阻力起作用,較佳為使螺釘頭為平緩之曲面狀,或設置較大之槽。又,藉由使螺釘頭表面較背面材12為粗面,亦於螺釘頭側殘留接著劑,作為剪切阻力起作用,故而有效。
Also, when the screw head sinks too much, before the
另一方面,於正面材11及背面材12較薄之情形時,為了讓正面材11
及背面材12在螺釘頭之細微之行為之下不易出現歪曲,而強行以螺釘頭與正面材及背面材並不接著之方式進行設計。
On the other hand, when the
為了不使拉拔方向之頭部陷落強度過大,提高鉛直方向之耐力,關鍵在於不使螺釘頭之直徑過大而使之較厚。 In order not to make the head sink strength in the pulling direction too large and improve the endurance in the vertical direction, the key is not to make the diameter of the screw head too large and make it thicker.
若考慮該等情況,則鍋頭之螺釘較佳為使用軸部直徑4~7Φ,頭部直徑9~15Φ,頭部厚度4~9mm左右者,於盤頭之情形時,較佳為使用軸部直徑4~6Φ,頭部直徑9~15Φ,盤頭之角度為30~60°左右者。又,錨定材A及螺釘V係自正面材11側與背面材12側之兩者打入,較佳為,以其等不干涉之方式,相隔無機板層厚度之1.5倍以上打入,進而較佳為相隔2倍以上打入。再者,若使用螺釘V,則不會產生由賦予至打設時之無機板層15之打擊等所致之損傷,於欲使打入錨定材A及螺釘V之間隔較小之情形時較佳。
If these circumstances are considered, it is better to use a shaft diameter of 4~7Φ, a head diameter of 9~15Φ, and a head thickness of about 4~9mm for the screw of the pan head. In the case of a pan head, it is better to use a shaft The head diameter is 4~6Φ, the head diameter is 9~15Φ, and the angle of the pan head is about 30~60°. In addition, the anchor material A and the screw V are driven in from both the side of the
此處,對用以使包括分隔用板1之分隔壁(參照圖4A及圖4B所示之本發明之分隔壁2)於1小時之加熱及3小時之跟蹤之耐火試驗合格之方法進行說明。於將分隔壁2自正面材11側加熱之情形時,正面材11於加熱初期大幅度變形,加熱側之有機隔熱板層13於1小時之加熱時間中碳化之後消失。然後,必須使無機板層15、非加熱側之有機隔熱板層14及背面材12之3層直至最後其位置關係不破壞,防止火焰或熱之貫通。
Here, the method for passing the fire resistance test of heating for 1 hour and tracking for 3 hours for the partition wall including the partition board 1 (refer to the
該3層係首先於樓板22、23等主體藉由上部錨定材24b及下部錨定材
25b而固定上部安裝材24c及下部安裝材25c(以下,有時將上部安裝材24c及下部安裝材25c合併簡稱為「安裝材」),利用上部安裝材24c及下部安裝材25c將分隔用板1向面外方向約束。於上部安裝材24c及下部安裝材25c分別使用上部固接材24a及下部固接材25a(以下,有時將上部固接材24a及下部固接材25a合併簡稱為「固接材」)緊固於背面材12。其次,將非加熱側之有機隔熱板層14藉由有機系接著劑而固定於背面材12。最後,將無機板層15使用有機系接著劑及機械固定手段固定於有機隔熱板層14。
The 3-layer system first uses the
上部安裝材24c及下部安裝材25c係使用不鏽鋼鋼板或熔融鋅鍍覆鋼板,考慮設想之地震力或火災時之熱之變形來設計,作為上部安裝材24c,較佳地使用厚度2~6mm且鉛直方向40~100mm、水平方向30~60mm左右之剖面者,作為下部安裝材25c,較佳地使用厚度2~6mm且鉛直方向40~100mm、水平方向30~60mm左右之剖面者。上部安裝材24c及下部安裝材25c之長度係根據施工方法來設計,但若施工時之一側使用1.8~5.4m左右者,另一側使用0.1~0.9m左右者,則可實現如於施工時首先建成較長者、且利用較短者以不倒之方式壓入之施工,故而方便。
The
上部安裝材24c及下部安裝材25c具備錨定材施工用之貫通孔及固接材施工用之貫通孔。藉由於上部安裝材24c及下部安裝材25c預先設置固接材施工用之貫通孔,能夠使用薄鋼板用之自攻螺釘以將正面材11及背面材12固定。其等係直徑為4~5Φ,長度為15~30mm,螺紋高度為0.4~1.0,螺紋間距為0.5~1.0左右,小型但施工為薄鋼板之情形時之剪切力、
與拉拔相關之耐力及直至破壞為止之變形能力優異,故而較佳。

為了於火災時上述3層自立,僅利用非加熱側之上部固接材24a於鉛直方向支持背面材12與固著於背面材12之有機隔熱板層14及無機板層15之重量之自重。壁材通常時自兩面藉由安裝材夾住而不會傾倒,但於火災時壁材剖面之加熱側之有機隔熱板層13消失,而大幅度變形。因此,於非加熱側之上部固接材24a經由背面材12而產生與背面材12及固著於背面材12之有機隔熱板層14及無機板層15之重量對應的剪切力、以及與藉由熱之變形而產生之偏心對應之拉拔力,故而必須充分地考慮該等進行設計。
In order for the above three layers to be self-supporting in the event of a fire, only the
該3層由於在3小時之跟蹤試驗之最終向面外大幅度彎曲,故而必須考慮彎曲時之影響進行設計。進而,於在上部固接材24a產生鉛直方向之位移及旋轉之情形時,於本發明之構造中,固接材配置於背面材12及有機隔熱板層14內。
Since the 3 layers were largely bent out of the plane at the end of the 3-hour tracking test, it was necessary to consider the influence of bending when designing. Furthermore, when the
無機板層15即便為較小之局部負載亦容易產生破裂,但不受上部固接材24a之位移及旋轉之影響,不會損及作為防火材之功能。另一方面,由於有機隔熱板層14包括柔軟之材料,故而亦不會產生如因上部固接材24a之位移及旋轉之影響而使熱容易地傳遞至背面材12之損及耐火性之缺損及脫落等。
The
為了讓上部固接材24a支持上述3層之自重,較佳為上部固接材24a貫通之上部安裝材24c之孔於鉛直方向不具有較大之遊隙,設為圓孔或長徑
為10~20mm左右之長孔。再者,設置於下部安裝材25c之下部固接材25a之貫通用孔亦可為圓孔,但為了吸收因上述鉛直方向之自重而產生於壁材之位移,較佳為將長徑設為20~40mm左右。
In order for the
如上所述,於圖3A及圖3B中,於無機板層15之兩面分別配置有2層之有機隔熱板層13、14,將與無機板層15相鄰之有機隔熱板層13機械固定於無機板層15。於該情形時,錨定材A及螺釘V之頭部埋沒於相鄰之有機隔熱板層13,故而無問題。
As mentioned above, in FIG. 3A and FIG. 3B, two layers of organic heat-insulating board layers 13 and 14 are arranged on both sides of the
另一方面,如圖3C所示,於無機板層15之兩面分別配置有1層之有機隔熱板層13,於將有機隔熱板層13、14固定於無機板層15之情形時,錨定材A及螺釘V之頭部接觸於包括金屬材之正面材11及背面材12。因此,較佳為,將收容錨定材A及螺釘V之頭部之凹部設置於有機隔熱板層13、14之正面材11及背面材12側之表面。
On the other hand, as shown in FIG. 3C , one layer of organic heat-insulating
但是,若將錨定材A或螺釘V之頭部之形狀設為相對較薄,進而於打入頭部背面側時容易埋沒於有機隔熱板層13、14之形狀,則無須預先設置上述凹部。 However, if the shape of the anchor material A or the head of the screw V is set to be relatively thin, so that it is easy to be buried in the shape of the organic heat insulation board layers 13, 14 when it is driven into the back side of the head, then it is not necessary to pre-install the above-mentioned recessed part.
又,若將錨定材A或螺釘V之頭部之有機隔熱板13、14之陷入強度設計得較向無機板層15之固定強度更小,則於拉伸力作用於錨定材或螺釘V時亦可防止無機板15損傷,自耐火性之方面而言更佳。
Also, if the sinking strength of the anchor material A or the
其次,對本發明之分隔壁進行說明。圖4A表示本發明之分隔壁之較佳之一例之整體圖。又,圖4B表示圖4A所示之分隔壁之鉛直方向剖視圖。該圖所示之分隔壁2係架設於建築物之樓層間,即樓板22、23之間,且利用其上下端固定之縱式之分隔壁。分隔壁2除了固定於樓板以外,亦可固定於配置在天花板或地板之耐火被覆之鋼架樑等。又,於必須在地板面亦配置隔熱材之用途之情形時,於該分隔壁之兩面自樓板面堆積隔熱材之後,對該隔熱材上打設混凝土作為地板面完工之情況亦較多。分隔壁2係將上述本發明之分隔用板1以複數片於寬度方向相鄰而配置。
Next, the partition wall of the present invention will be described. Fig. 4A shows an overall view of a preferred example of the partition wall of the present invention. 4B is a vertical cross-sectional view of the partition wall shown in FIG. 4A. The
圖5表示本發明之分隔壁2之寬度方向剖視圖,圖5A係整體圖,圖5B係板間之接縫部分之放大圖。較佳為於上述複數片板1之切口間填充有熱膨脹性片材21。該熱膨脹性片材21並非裝填於板1之全厚,而如圖5B所示,僅裝填於加熱時間中及加熱後具有強度且殘存之無機板層15之部分則效率最好。進而,熱膨脹性片劑21未必需要裝填於無機板層15之全厚,只要考慮設想之無機板層15間之間隙與熱膨脹性片材21之膨脹率等決定即可,較佳為厚度為1~3mm、寬度為15~50mm左右者。又,於板1間之接縫打設有密封材28。
Fig. 5 shows a cross-sectional view in the width direction of the
分隔壁2之下部藉由下部固接材25a及下部錨定材25b介隔下部安裝材25c而固定於樓板23。雖然未圖示,但分隔壁2之上部亦同樣地,藉由上部固接材24a及上部錨定材24b介隔上部安裝材24c而固定於樓板22。又,於分隔壁2與樓板22之間之接縫填充有上部接縫材26,於分隔壁2與樓板
23之間之接縫填充有下部接縫材27。
The lower part of the
上部錨定材24b及下部錨定材25b係選擇可耐於作為通常之分隔壁之設計負載之地震時起作用之1G左右之慣性力者,一般而言,將直徑為M8~10左右、埋入長度為30~70mm左右之混凝土用錨定材根據可負擔之耐力而配置需要根數。
The
作為填充於上述複數片板1間之接縫之熱膨脹性片材21,可使用與用於將上述無機板層15排列複數片之情形時之接縫之熱膨脹性片材相同者。
As the heat-
又,上部接縫材26及下部接縫材27係用以於火災時於壁材產生位移或旋轉之情形時不產生使火焰或熱貫通之間隙,又不產生損及作為壁材之防火材之功能之缺損或脫落,進而於平常時使熱貫流變小之材料。作為上部接縫材26及下部接縫材27,可使用陶瓷纖維、鹼土矽酸鹽毛毯(生物溶解性纖維)等。
Also, the upper
圖6表示板1間之接縫構造之例。於圖6A所示之接縫構造中,正面材11(背面材12)沿著將有機隔熱板層13(14)之凹部13a(14a)劃分之側壁彎折1次形成第一彎折部11a、12a,於相鄰之第一彎折部11a相互間填充有密封材28。
FIG. 6 shows an example of a joint structure between
再者,密封材28只要其底面為接著於有機隔熱板層13(14),但於凹部13a(14a)處露出未貼附有面材之樹脂層之面,則不會阻礙密封之自由變
形。
Furthermore, as long as the bottom surface of the sealing
又,於圖6B所示之接縫構造中,正面材11(背面材12)沿著將有機隔熱板層13(14)之凹部13a(14a)劃分之側壁及底面彎折2次,形成第一彎折部11a、12a及第二彎折部11b、12b。藉由將第二彎折部11b(12b)相互間連結,可於火災時緩和來自分隔用板1之接縫部之火熱之侵入,並且可避免由來自相鄰之正面材11a間之加熱所致之熱之直射,提高耐火性。
In addition, in the seam structure shown in FIG. 6B, the front material 11 (back material 12) is bent twice along the side wall and the bottom surface that divide the
第二彎折部11b(12b)無須遍及板1之全長而形成,例如,亦可以300~1500mm左右之間隔利用鉚釘固定或焊接等方法來固著於第一彎折部11a、12a。而且,於正面材11(背面材12)之相互間積層之部分利用螺釘V以300~1500mm左右之間隔連結,於相鄰之第一彎折部11a相互間填充有密封材28。
The second
藉由上述連結,亦可減少接縫部之移動,使密封高壽命化。又,寬度方向之最外部由包括金屬材之正面材11或背面材12構成,故而可防止作為芯材之有機隔熱板層13、14及無機板層15之切口之損傷。進而,於作為分隔壁之建入時,包括金屬材之正面材11及背面材12之出入調節變得容易。
Through the above connection, the movement of the seam can also be reduced, and the life of the seal can be increased. Moreover, the outermost part in the width direction is composed of the
再者,於第二彎折部11b(12b)之面外側敷設有用以防止密封材28之三面接著之防黏結材料(bond breaker)29。再者,亦可代替防黏結材料29而使用發泡樹脂製之襯墊料,但該等材料多為於作為耐火試驗中之背面溫
度之規定值之180+氣氛溫度附近具有收縮性狀者,導致自加熱相反側之密封之底面側之附著斷開,有使耐火性降低之虞,故而需要注意。
Furthermore, an anti-adhesive material (bond breaker) 29 for preventing the three sides of the sealing
圖6C表示圖6B所示之接縫構造之較佳之態樣。於圖6B所示之分隔壁中,相鄰之分隔用板中之一者(於圖6B中為左側之分隔用板)之第二彎折部11b及12b之兩者配置於有機隔熱板層13、14側。
Fig. 6C shows a preferred form of the seam structure shown in Fig. 6B. In the partition wall shown in FIG. 6B, both of the second
相對於此,於圖6C所示之接縫構造中,相鄰之分隔用板1a、1b中之1a之正面材11之第二彎折部11bi配置於有機隔熱板層13側,相鄰之另一個分隔用板1b之第二彎折部11bo配置於螺釘V側。又,分隔用板1a之背面材12之第二彎折部12bo配置於螺釘V側,另一個分隔用板1b之第二彎折部12bi配置於有機隔熱板層14側。
In contrast, in the seam structure shown in FIG. 6C , the second bent portion 11bi of the
藉由如此構成,可於相鄰之分隔用板1a之第二彎折部11bi與12bo之間隔和另一個分隔用板1b之第二彎折部11bo與12bi之間隔存在誤差之情形時亦容易於現場建入。即,於接著預先於特定之位置施工之分隔用板1a繼續施工下一分隔用板1b時,使各分隔用板之第二彎折部11bi與11bo及12bo與12bi以於厚度方向稍微錯開之狀態以使寬度方向成為特定尺寸之方式牽引之後於厚度方向壓入至特定位置為止,藉此,第二彎折部彼此不會碰撞,可容易地施工。
With such a configuration, it is possible to easily fix the gap between the second bent portions 11bi and 12bo of the
又,於圖6C所示之接縫構造中,螺釘V之位置偏向第一彎折部11a(12a)側而配置,並且與有機隔熱板層13、14相鄰之第二彎折部
11bi(12bi)之寬度方向之長度較長。藉此,可使螺釘V之擰入至第二彎折部11bo、11bi、12bo及12bi之螺釘V之邊隙變大,可提高相鄰之分隔用板彼此之連結強度。又,於因各種因素而於施工現場中較設計值擴大接縫寬度進行施工時,亦可容易確保強度上需要之邊隙。
In addition, in the seam structure shown in FIG. 6C, the position of the screw V is biased toward the
進而,於圖6C所示之接縫構造中,熱膨脹性片材21偏向相鄰之分隔用板1a、1b中之一個(於圖6C中為1b)而配置。藉此,於在相互相鄰之分隔用板1a、1b之間配置熱膨脹性片材21時,只要使一個分隔用板之無機板層15之寬度變短而設置凹部,於所設置之凹部填充熱膨脹性片材21即可,故而可使施工性大幅度提高。再者,如圖6C所示,亦可於無機板層15與熱膨脹性片材21之間空開間隙(例如,於寬度方向為1mm左右)。
Furthermore, in the joint structure shown in FIG. 6C, the heat-
如上所述,本發明之分隔壁2由於利用其上下端固定於主體,故而於將分隔壁2之正面材11(背面材12)加熱時,正面材11(背面材12)膨脹,可使正面材11(背面材12)與有機隔熱板層13(14)剝離,板層13、14、15不會變形而破損,可保持分隔壁2之耐火性。如此,本發明之分隔壁2係兼備較高之耐火性與隔熱性者。
As mentioned above, the
繼而,對本發明之房間構造進行說明。圖7係表示本發明之房間構造之一例。該圖所示之房間構造3係將包括屋頂31、地板32及外壁33之建築物之內部藉由上述本發明之分隔壁2而分隔,進而於該分隔壁2之中間位置連接高隔熱性之天花板材34a(35a),藉此,於至少該分隔壁2之一者,具
有由該分隔壁2與該天花板材34a(35a)及壁材34c(35c)、地板材34b(35b)而分隔之房間34(35)。而且,該房間34(35)由高隔熱性之地板材34b(35b)及壁材34c(35c)與分隔壁2及天花板材34a(35a)而劃分。上述房間34(35)例如為冷凍冷藏庫。
Next, the room structure of this invention is demonstrated. Fig. 7 shows an example of the room structure of the present invention. The
又,建築物之屋頂31、地板32、外壁33包括例如混凝土或輕量氣泡混凝土等。再者,該分隔壁2之上部並不固定於屋頂31,亦可根據建築物構造而固定於上層之地板或耐火被覆之鋼架或鐵筋混凝土製之樑。又,於圖7中於地板32之上,設置有地板材34b、35b,但藉由將隔熱材配置於地板32之下側,而地板面之強度提高,方便貨物搬運車輛等之行駛。
Also, the
如圖8所示,於先前之冷凍冷藏倉庫之房間構造30中,使用具有耐火性之輕量氣泡混凝土等之分隔壁20,冷凍冷藏庫等房間36(37)由高隔熱性之天花板材36a(37a)、地板材36b(37b)及壁材36c(37c)而劃分。然而,由於壁材36c(37c)與成為防火劃分區域之分隔壁20之間成為空調溫度不同之空間,故而容易於隔熱板之表面產生冷凝,進而該等空間狹窄難以清掃,故而存在容易產生黴或蟲害之問題。
As shown in Fig. 8, in the
相對於此,於本發明之房間構造3中,兼備較高之隔熱性及耐熱性之分隔壁2構成房間34(35)之壁之一部分。藉由如此構成,而於如先前之房間構造30中所存在之壁材34c(35c)與分隔壁2之間不存在間隙。其結果,不易於分隔壁2中產生冷凝,可抑制黴或蟲害。
On the other hand, in the
又,如圖9A表示圖7所示之分隔壁2與隔熱材34a、34b之連接部分之放大圖般,於分隔壁2中,將熱導率相對較高之無機板層15配置於分隔壁2(分隔用板1)之中央,將熱導率相對較低之有機隔熱板層13、14配置於外側。因此,於貫通房間34(35)之內外之板之表層部傳遞之熱量變少,不易產生熱橋。相對於此,於使用如圖9B所示之將有機隔熱板層13、14與無機板層15調換之分隔壁之情形時,由於表層部附近包括容易傳遞熱之材料,故而產生較圖9A之構造大之熱橋。
Also, as shown in FIG. 9A showing an enlarged view of the connection portion between the
以下,對本發明之實施例進行說明,但本發明並不限定於實施例。 Hereinafter, examples of the present invention will be described, but the present invention is not limited to the examples.
製作本發明之分隔用板1。首先,分別準備作為正面材11及背面材12之塗裝鋁鋅矽熱鍍鋼板(註冊商標)2片(尺寸:3200mm×890mm,四周帶有10mm寬之彎折部,厚度:0.4mm),作為有機隔熱板層13、14之酚發泡體板4片(旭化成建材股份有限公司製造NEOMA FOAM(註冊商標),尺寸:1820mm×900mm,厚度32.5mm,密度:40kg/m3),作為無機板層15之輕量氣泡混凝土3片(旭化成建材股份有限公司製造Powerboard NEXT,尺寸:1820mm×606mm,厚度:36mm,密度350kg/m3)。
The
其次,將塗裝鋁鋅矽熱鍍鋼板(註冊商標)、酚發泡體板、輕量氣泡混凝土、酚發泡體板、塗裝鋁鋅矽熱鍍鋼板(註冊商標)依序使用胺基甲酸酯系接著劑(小西股份有限公司製造KU570)來積層接著。接著劑之塗佈量係
塗裝鋁鋅矽熱鍍鋼板(註冊商標)與酚發泡體板之間設為150~200g/m2,輕量氣泡混凝土與酚發泡體板之間設為200~300g/m2,以施加1t/m2之加壓之狀態進行1晚之養護。如此一來,獲得分隔用板1。
Secondly, the coated aluminum-zinc-silicon hot-dip steel sheet (registered trademark), phenol foam board, lightweight cellular concrete, phenol foam board, and coated aluminum-zinc-silicon hot-dip steel sheet (registered trademark) are sequentially applied with amino groups Formate-based adhesive (KU570 manufactured by Konishi Co., Ltd.) was used for lamination and adhesion. The coating amount of the adhesive is set at 150~200g/ m2 between the coated aluminum-zinc-silicon hot-dip steel plate (registered trademark) and the phenolic foam board, and between the light-weight cellular concrete and the phenolic foam board. 200~300g/m 2 , with a pressure of 1t/m 2 for 1 night curing. In this way, the
將4片以上述方式獲得之分隔用板1於寬度方向相鄰地配置,將各板1之上部及下部藉由上部安裝材(L-65×40×t=3.2mm)及下部安裝材(L-50×40×t=3.2mm)分別固定於天花板及地板。又,於板1間之接縫與板1內之輕量氣泡混凝土間之接頭裝填熱膨脹性片材(CRK股份有限公司製造Fireshut FST-A,厚度2mm×寬度30mm)。如此一來,將本發明之分隔壁2架設於建築物之樓層間。
Arrange the 4
關於以上述之方式準備之發明例1,根據建築基準方法中規定之方法,進行分隔壁耐火1小時之試驗。以下,對耐火試驗中之發明例1之分隔壁2之行為進行說明。
Regarding Invention Example 1 prepared in the above manner, a fire resistance test of the partition wall for 1 hour was carried out according to the method prescribed in the Building Standards Method. Hereinafter, the behavior of the
首先,如圖10(a)所示,若將分隔壁(分隔用板1)之正面材11利用燃燒器加熱,則圖10(b)所示,自剛加熱開始之後(自開始後5分鐘左右),正面材11開始向加熱側大幅度膨脹。此時,於板1中,正面材11與有機隔熱板層13由於利用有機系接著劑接著,故而於(300~400℃左右)加熱開始後數分鐘,有機系接著劑燃燒並消失,正面材11與有機隔熱板層13剝離,正面材11向加熱側變形。
First, as shown in FIG. 10(a), if the
若繼續加熱,則有機隔熱板層13以接著於無機板層15之狀態碳化。此時,由於正面材11向加熱側鼓出,故而有機隔熱板層13於碳化時向板1之厚度方向自由地膨脹,其結果,形成較厚之隔熱層,其結果,進入至無機板15之熱有效地被遮斷。而且,於60分鐘之加熱之時間內,如圖10(c)所示,有機隔熱板層13幾乎全部碳化。
If the heating is continued, the organic heat-insulating
自加熱開始經過60分鐘時停止加熱。隨即,板1所面對之耐火爐內之氧濃度急遽地增加,如圖10(d)所示,碳化之有機隔熱板層13再次燃燒固定時間。於本發明之板1中,於有機隔熱板層13碳化時,由於正面材11鼓出,故而有機隔熱板層13之表面不完全密閉,以低氧之狀態碳化。因此,正面材11與有機隔熱板13不剝離,與有機隔熱板層13以無氧狀態碳化之情形時相比,上述再燃燒時之產生熱量或燃燒時間較小。
Heating was stopped when 60 minutes had elapsed from the start of heating. Immediately, the oxygen concentration in the refractory furnace facing the
然後,如圖10(e)所示,碳化之有機隔熱板層13逐漸自無機板層15之表面脫落。於脫落之部分,露出之無機板層15之表面直接受熱影響而進行脫水,如圖10(f)所示,於無機板層15之表面產生龜裂C。
Then, as shown in FIG. 10( e ), the carbonized organic thermal
而且,如圖10(g)所示,若碳化之有機隔熱板層13自無機板層15脫落,則因伴隨脫水之收縮與溫度下降,而於無機板層15產生較多之龜裂C。隨著脫落部分增加,而於無機板層15產生較多之龜裂。繼而,若抑制脫落與龜裂之產生,則因爐內溫度降低而無機板層15之溫度降低,由溫度變化所致之收縮開始。然而,於該狀態下無機板層15亦不會倒塌,可確保分隔壁2之耐火性能。進而,於本發明例1之板1中,由於在內部裝填有補
強材,故而龜裂稍微擴展但板整體之尺寸變化變小,可防止板間之接縫大幅度擴展。因此,無機板層15內之龜裂、1片板內之無機板15a間之接縫、相鄰之板間之接縫均不會變大。作為其結果,無機板15a僅局部地碳化即可,又,關於非加熱側之有機隔熱板層14,亦如圖10(h)所示,僅局部形成有碳化部P之程度即可,整體上可滿足耐火性能。
Moreover, as shown in FIG. 10(g), if the carbonized organic heat-insulating
圖11係表示耐火試驗中之時間與分隔壁之溫度之關係的圖,圖11A係加熱溫度(爐內溫度),圖11B係背面溫度,表示15個熱電偶之測定結果。根據圖11A可知,加熱溫度(爐內溫度)自剛加熱開始之後急遽地上升,於加熱開始後1小時上升至930℃左右,若停止加熱,則溫度急遽地降低,自加熱停止3小時後降低至180℃左右。
Fig. 11 is a graph showing the relationship between the time and the temperature of the partition wall in the fire resistance test. Fig. 11A is the heating temperature (furnace temperature), and Fig. 11B is the backside temperature, showing the measurement results of 15 thermocouples. According to Fig. 11A, it can be seen that the heating temperature (furnace temperature) rises sharply immediately after the start of heating, and rises to about 930°
相對於此,根據圖11B可知,背面溫度於加熱開始後逐漸上升,即便加熱開始後經過1小時亦不到達至100℃。然而,於加熱結束後溫度上升固定時間,最大上升至120℃左右。然後,溫度逐漸降低,自加熱停止3小時後降低至70℃左右。如此,於耐火試驗之期間,背面溫度維持為最大值未達180℃+氣氛溫度(25℃),平均溫度未達140℃+氣氛溫度(25℃)。
On the other hand, as can be seen from FIG. 11B , the back surface temperature gradually increased after the heating was started, and did not reach 100° C. even after 1 hour after the heating was started. However, after the end of heating, the temperature rises for a fixed time, and the maximum rises to about 120°C. Then, the temperature was gradually lowered to about 70°
根據本發明,可提供兼備較高之耐火性與耐熱性之分隔用板,進而將其長條地使用之房間構造。 According to the present invention, a partition board having high fire resistance and heat resistance can be provided, and a room structure in which the board is used in a long strip can be provided.
