鋁卷板及鋁平板在建筑上的使用

來(lái)源:http://www.menguosenlin.cn/ 發(fā)布時(shí)間:2018-10-08

建筑上使用的鋁板包括單層鋁板、復(fù)合鋁板等多種材料,一般常常指單層鋁板(也有叫單鋁板或純鋁板),多用于建筑裝飾工程中,近年來(lái)在鋁板幕墻中單層鋁板使用的較為多見(jiàn)。鋁板幕墻也是幕墻的一種形式,簡(jiǎn)單地說(shuō)是用鋁板代替玻璃制成幕墻,鋁板幕墻多用于作墻體蔽護(hù)和不采光的墻壁。
Aluminum sheets used in buildings include single-layer aluminum sheets, composite aluminum sheets and other materials, often referred to as single-layer aluminum sheets (also known as single-layer aluminum sheets or pure aluminum sheets), mostly used in building decoration projects, in recent years in the use of single-layer aluminum curtain wall is more common. Aluminum plate curtain wall is also a form of curtain wall, simply speaking, using aluminum plate instead of glass curtain wall, aluminum plate curtain wall is mostly used for wall protection and lighting wall.
國(guó)外的鋁板幕墻一直選用單層鋁板。單層鋁板一般用純鋁板。鋁板厚度為3mm,為了加強(qiáng)鋁板板面強(qiáng)度,在鋁板的背面,必須安裝加強(qiáng)筋(現(xiàn)有的廠(chǎng)家不安),加強(qiáng)筋用厚的鋁帶做成,先用閃光焊機(jī)把一顆顆螺絲帽焊在鋁板背面然后把作加強(qiáng)筋的鋁條鉆孔套進(jìn)螺絲內(nèi),用螺絲固定。我國(guó)為了減輕鋁板重量,增加鋁板強(qiáng)度,我們采用鋁合金板,常選用21號(hào)防銹鋁代號(hào)LF21壓成的鋁板作幕墻鋁板。鋁板厚度由原來(lái)3mm減少為2.5mm,該合金強(qiáng)度比純鋁板高出一倍左右。加強(qiáng)筋用LF21鋁帶,鋁帶的寬度厚度根據(jù)鋁板板面而定,一般厚2-2.5mm,寬10-25mm。鋁板幕墻的鋁板背面為什么要安加強(qiáng)筋,是在外界正負(fù)壓力的情況下,鋁板一不會(huì)凹陷,二不會(huì)鼓出,這樣就避免了鋁板幕墻反復(fù)里外振動(dòng)而發(fā)出的振動(dòng)聲音。如果需要隔音保溫,可在鋁板內(nèi)側(cè),安放巖棉、礦渣棉或發(fā)泡處理。
The aluminum sheet curtain walls abroad have been selected for single layer aluminum plates. Single layer aluminum plates are usually made of pure aluminum plates. Aluminum plate thickness is 3mm, in order to strengthen the strength of the aluminum plate, in the back of the aluminum plate, must install reinforcement ribs (existing manufacturers are uneasy), reinforcement ribs made of thick aluminum strip, first with flash welding machine to weld a screw cap on the back of the aluminum plate and then the reinforcement of the aluminum rod borehole into the screw, fixed with screws. In order to reduce the weight of aluminium plate and increase the strength of aluminium plate, we use aluminium alloy plate. Aluminum plate made of No. 21 rust-proof aluminium code LF21 is often used as curtain wall aluminium plate. The thickness of aluminum plate is reduced from 3mm to 2.5mm, which is twice as high as that of pure aluminum sheet. LF21 aluminum strip is used for reinforcing ribs. The width and thickness of the aluminum strip are determined by the surface of the aluminum plate. Generally, the thickness is 2-2.5mm and the width is 10-25mm. The reason why the back of aluminum curtain wall should be strengthened is that under the positive and negative external pressure, the aluminum plate will not be sunken, two will not bulge, thus avoiding the aluminum curtain wall repeated inside and outside vibration and the vibration sound. If sound insulation is needed, the rock can be placed on the inside of the aluminum sheet, with rock wool, slag wool or foam treatment.

鋁板生產(chǎn)廠(chǎng)家
幕墻鋁板表面處理,可分為二種方法,一種是陽(yáng)極氧化,另一種是靜電噴涂。陽(yáng)極氧化的氧化膜一般在12μ以上,顏色只有古銅色和白色兩種,顏色單調(diào),更為嚴(yán)重的缺點(diǎn)是每塊鋁板板面的顏色深淺不一,許多塊幕墻板組合在一起形成一個(gè)幕墻整體效果非常難看。這個(gè)缺點(diǎn)可以說(shuō)無(wú)法消除,并非生產(chǎn)技術(shù)造成的,而是由于鋁板并非是由一批號(hào),化學(xué)成份,均有小的差別,再加上氧化時(shí)電解槽液電流密度等因素均無(wú)法完全一樣,所以氧化后的顏色多少均有差異,單張看可能不明顯,若都排在一起即非常明顯。所以鋁板幕墻的鋁板表面處理,決不能用陽(yáng)極氧化。
Curtain wall aluminum surface treatment can be divided into two methods, one is anodic oxidation, the other is electrostatic spraying. Anodized oxide film is generally more than 12 mu, the color is only bronze and white, the color is monotonous, the more serious drawback is that the color of each aluminum plate surface is different, many curtain wall panels together to form a curtain wall overall effect is very ugly. This disadvantage can not be eliminated, not due to production technology, but because the aluminum plate is not a batch number, chemical composition, there are small differences, coupled with oxidation when the electrolyte current density and other factors can not be completely the same, so the number of colors after oxidation are different, a single look may not be obvious, if all are That is very obvious. Therefore, the surface treatment of aluminum plate curtain wall must not be anodized.
幕墻鋁板表面處理的另一種方法是靜電噴涂。噴涂又分為粉沫噴涂和液體噴涂。粉沫噴涂材料主要為:聚氨酯、聚脹樹(shù)脂、環(huán)氧樹(shù)脂等原料配以高保色性顏料,可得到幾十種不同顏色的噴涂粉沫。該噴涂粉沫,耐撞碰耐磨擦,在50公斤撞擊下,鋁板變形,噴涂層無(wú)裂紋,無(wú)掉層完整無(wú)損,抗稀酸及砂漿。的缺點(diǎn)怕紫外線(xiàn)長(zhǎng)期照射,幾年后易產(chǎn)生陰陽(yáng)面顏色的差異。
Another way of surface treatment of aluminum curtain wall is electrostatic spraying. Spraying is divided into powder spray and liquid spray. Powder spraying materials are mainly polyurethane, swelling resin, epoxy resin and other raw materials with high color retention pigments, can get dozens of different colors of spraying powder. The spraying powder, collision resistance and abrasion resistance, 50 kg impact, aluminum plate deformation, spray coating without cracks, no drop layer integrity and no damage, dilute acid and mortar. The only shortcoming is that the long term exposure to ultraviolet radiation will lead to differences in color between yin and Yang after a few years.
