        U型玻璃介紹 Introduction to u-shaped glass


        U型玻璃(U-Profile-Glass)亦稱槽型玻璃,在國內是一種新型的建材玻璃,在國外有近40年的生產應用歷史。U型玻璃工業與民用建筑非承重的內外墻、隔斷、窗、陽臺、過道、屋面及附屬建筑物。按表面處理方式不同,有普通壓花玻璃、夾絲玻璃、彩色玻璃等。U型玻璃透光而不透視,條狀造型具有挺拔、朦朧、清秀、流暢的美感和時代氣息,有著獨特的裝飾效果。


        1特性與優點:

        1.1輕巧透光,可增加建筑物使用面積和采光面積。

        雙層安裝的槽型玻璃墻體每平方米重量為40Kg,顯而易見槽型玻璃不但減輕了建筑結構的自重,而且省去了內外墻的粉刷,槽型玻璃是一種中高檔墻體材料,還可以代替一般不需要透明的采光窗、天窗,可節約大量木材、鋼材和鋁材,造價可節約三分之一。


        1.2 隔音、隔熱,改善環境節約能源

        雙層安裝的U型玻璃墻體,由于兩層間有空氣層,因此具有隔音、隔熱功能。資料介紹雙層槽型玻璃隔音為40分貝,傳熱系數為3W/m2.K,而單層6mm玻璃的傳熱系數為5.8W/m2.K。


        1.3理想的安全、耐腐蝕、

        使用夾鋼絲的U型玻璃,對于中高層建筑的墻體可以起到良好的安全保護作用;槽型玻璃抗酸、堿和高濕度作用的性能相當穩定,可用于有抗腐蝕要求的建筑上;


        1.4安裝方便,經濟實用

        在國外,安裝雙排垂直式槽型玻璃幕墻,如高3m,長10m,總面積30m2的槽型玻璃幕墻,一人僅用一小時就可以完成。


        2.在建筑設計中的應用


        2.1 現行玻璃有兩種規格:260(底寬)*41(翼高)*6(厚度)的156/平方米.260*60*7的176元/平方米。面積計算:底寬*玻璃長度。


        2.2 U型玻璃按造型及建筑使用功能分別采取以下組合方式: 


        1)單排 翼朝外(或內)

         

        2)單排 楔形結構,互相咬合

         

        3)單排 楔形結構,互相貼合

         

        4)雙排 翼在接縫處成對排列

         

        5)雙排 翼對翼

         

        2.3 注意:U型玻璃隔墻長度大于6000,高度超過4500時,應核算墻身的穩定,采取相應的措施。

        U型玻璃用于濕度較大的房間且室內外溫差較大時,應處理好玻璃表面露水的排泄及下滴問題。U型玻璃用于圓型墻及屋面時,曲率半徑不應小于1500。節點構造詳見國家標準圖集《U型玻璃外裝修標準06J501》。


        2.4其他:

        透光率:當表面有小花紋裝一排時為89%,裝兩排時81%。

        傳熱系數:①單排安裝時3.65W/m2K。②雙排安裝時1.74W/m2K。 ③貼膜時1.57 W/m2K ④填充保溫層1.2 W/m2K

        隔聲能力:單排安裝時27db,雙排安裝時38dB。

        耐火極限:0.75h(單排)。U型玻璃屬不燃燒材料,如有特殊要求時應按有關規范進行設計。 


        2.5設計標準:

        1)異型玻璃(國家標準報批稿) 

        2)5.1U型玻璃/Q KYB01-1997

        3)建筑工程質量檢驗評定標準GBJ301-88。

        4)中華人民共和國《U型玻璃外裝修標準06J501》


        2.6驗收標準:U型玻璃的驗收除參照建筑裝飾工程及驗收規范(JGJ73-91)第三、四章門窗工程及玻璃工程有關章節外,還應重點檢查:

        1)邊框是否直接固定在建筑上,之間的縫隙是否密封。邊框承受的荷載應直接傳給建筑,不應使U型玻璃受力。

        2)玻璃與玻璃之間,玻璃與邊框之間的縫隙,是否按上述要求進行密封。

        3)應使U型玻璃在框了中沿玻璃長度方向能自由伸縮,在上框料與U型玻璃之間要留有適當縫隙。

        4)為防止膨脹螺栓等固定件與框料之間相互接觸發生化學反應產生接觸腐蝕,在鋼膨脹螺栓等固定件與鋁框之間應用合成材料墊圈或油漆類物質隔開。




        U-profiled Glass, also known as slotted Glass, is a new type of building material Glass in China and has nearly 40 years of production and application history in foreign countries. U-shaped glass industrial and civil building non-bearing internal and external walls, partitions, Windows, balconies, corridors, roofing and ancillary buildings. According to the surface treatment, there are ordinary embossed glass, glass, color glass and so on. U-shaped glass penetrates light without perspective. The strip shape has a straight, hazy, delicate, smooth aesthetic feeling and flavor of The Times, and has a unique decorative effect.
        1 features and advantages:
        1.1 lightweight and transparent, which can increase the usable area and lighting area of the building.
        Double installation groove type glass wall body weight of 40 kg per square meter, obvious trough type glass not only reduced the weight of structures, and save the external walls of paint, trough type glass is a kind of high-grade wall materials, can also replace generally don't need the daylighting of the transparent window, skylight, can save a lot of wood, steel and aluminum, cost can save a third.
        1.2 sound insulation and heat insulation to improve the environment and save energy
        Double installation of u-shaped glass wall, because there is an air layer between the two, so it has sound insulation, heat insulation function. The heat transfer coefficient of the double-layer slotted glass is 3W/ m2.k, while the heat transfer coefficient of the single-layer 6mm glass is 5.8w/m2.k.
        1.3 ideal safety, corrosion resistance,
        The use of u-shaped glass with steel wire clip can play a good role in protecting the walls of middle and high-rise buildings. Fluted glass is stable in acid, alkali and high humidity, and can be used in buildings with corrosion resistance requirements.
        1.4 convenient installation, economical and practical
        In foreign countries, the installation of double row vertical trough glass curtain wall, such as 3m high, 10m long, the total area of 30m2 trough glass curtain wall, one person can be completed in one hour.
        2. Application in architectural design
        2.1 the current glass has two specifications: 156/ m2 of 260(bottom width)*41(wing height)*6(thickness), and 176 yuan/m2 of 260*60*7. Area calculation: bottom width * glass length.
        2.2 the u-shaped glass shall be combined in the following ways according to its modeling and architectural functions:
        1) single row wing facing outward (or inward)
        2) single row wedge structure, interlocking with each other
        3) single row wedge structure, fit each other
        4) double rows of wings are arranged in pairs at the joints
        5) double row wing to wing
        2.3 note: when the length of u-shaped glass partition is greater than 6000 and the height is more than 4500, the stability of the wall should be calculated and corresponding measures should be taken.
        When the u-shaped glass is used in the room with high humidity and the temperature difference between inside and outside is large, the problem of dew discharge and droplet on the glass surface should be dealt with well. When u-shaped glass is used for circular walls and roofing, the radius of curvature should not be less than 1500. Refer to national standard atlas "u-shaped glass exterior decoration standard 06J501" for details of node construction.
        2.4 other:
        Transmittance: 89% for one row with small pattern and 81% for two rows.
        Heat transfer coefficient: (1) 3.65w /m2K when single-row installation. (2) double row installation 1.74w /m2K. (3) 1.57w /m2K (4) fill the insulation layer 1.2w /m2K
        Sound insulation: 27db for single row and 38dB for double row.
        Fire resistance: 0.75h (single row). U-shaped glass is a non-combustible material. If there are special requirements, it should be designed according to relevant specifications.
        2.5 design standard:
        1) shaped glass (national standard approval draft)
        2)5.1 u-shaped glass /Q kyb01-1997
        3) construction engineering quality inspection and evaluation standard gbj301-88.
        4) u-shaped glass exterior decoration standard 06J501 of the People's Republic of China
        2.6 acceptance criteria: in addition to referring to the construction decoration engineering and acceptance code (jgj73-91) chapter iii and iv, the acceptance of u-shaped glass shall be focused on:
        1) whether the frame is fixed on the building directly and whether the gap between them is sealed. The load on the frame should be transmitted directly to the building and the u-shaped glass should not be stressed.
        2) whether the gaps between the glass and the glass, and between the glass and the frame should be sealed according to the above requirements.
        3) the u-shaped glass should be able to freely expand and contract along the length of the glass in the frame, and an appropriate gap should be left between the frame material and the u-shaped glass.
        4) in order to prevent the contact corrosion caused by the chemical reaction between the fixed parts such as expansion bolts and the frame material, synthetic material gaskets or paint materials should be applied between the fixed parts such as steel expansion bolts and the aluminum frame.
