建筑膠合板是(shi)一種三層或多層的板(ban)狀(zhuang)材料(liao)，是(shi)將木材紡成(cheng)單(dan)板(ban)或刨成(cheng)單(dan)板(ban)，然后用膠(jiao)粘(zhan)劑膠(jiao)合(he)而成(cheng)。通常采用奇數號單(dan)板(ban)，相鄰單(dan)板(ban)的纖維方向互相垂直(zhi)膠(jiao)合(he)。

建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)是一(yi)種三(san)層(ceng)或(huo)多(duo)層(ceng)的(de)(de)(de)(de)板(ban)(ban)(ban)(ban)(ban)狀材(cai)(cai)料，它是將木質型材(cai)(cai)切割成(cheng)單(dan)板(ban)(ban)(ban)(ban)(ban)或(huo)將木質型材(cai)(cai)刨成(cheng)薄木，然后用(yong)粘合(he)(he)劑粘合(he)(he)而成(cheng)。通常采用(yong)奇數號單(dan)板(ban)(ban)(ban)(ban)(ban)，相鄰單(dan)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)纖維方(fang)向(xiang)互相垂直膠(jiao)合(he)(he)。膠(jiao)建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)一(yi)般長寬規格(ge)為1220×2440毫(hao)米，厚度規格(ge)一(yi)般為3、5、9、12、15、18毫(hao)米等。其他規格(ge)的(de)(de)(de)(de)建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)都是小尺(chi)寸膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)，不常用(yong)于(yu)(yu)裝(zhuang)飾。多(duo)層(ceng)建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)是指7層(ceng)和(he)9層(ceng)以(yi)上，主要用(yong)于(yu)(yu)建筑(zhu)和(he)車(che)輛。了解建筑(zhu)膠(jiao)合(he)(he)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)規格(ge)和(he)尺(chi)寸非常重要。消(xiao)費(fei)(fei)者可以(yi)根(gen)據室(shi)內裝(zhuang)修(xiu)的(de)(de)(de)(de)面積要求(qiu)合(he)(he)理計算所需的(de)(de)(de)(de)材(cai)(cai)料。三(san)夾(jia)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)地(di)方(fang)不能用(yong)五夾(jia)板(ban)(ban)(ban)(ban)(ban)，以(yi)免盲目(mu)購買材(cai)(cai)料造成(cheng)不必要的(de)(de)(de)(de)浪費(fei)(fei)。

建(jian)(jian)筑(zhu)膠合板(ban)是(shi)由一些很薄的木片做成(cheng)的，偶(ou)爾會(hui)有奇數。根據(ju)(ju)不(bu)同層壓板(ban)的組合，建(jian)(jian)筑(zhu)膠合板(ban)的厚(hou)度會(hui)有所不(bu)同。一般有3%、5%、9%、12%、15%、18%等(deng)幾種規格(ge)。當然，根據(ju)(ju)特殊情(qing)況會(hui)有其他厚(hou)度。

建筑膠合板的密(mi)度一(yi)般(ban)在(zai)0.5-0.8之間。建筑(zhu)膠(jiao)合(he)板(ban)(ban)的密(mi)度越高(gao)，質(zhi)量越好。一(yi)般(ban)比同(tong)類木(mu)(mu)(mu)材大。膠(jiao)合(he)時單(dan)位(wei)壓力越高(gao)，建筑(zhu)膠(jiao)合(he)板(ban)(ban)的密(mi)度越高(gao)。由于木(mu)(mu)(mu)材在(zai)高(gao)溫下(xia)容易發(fa)生塑性變形，熱壓結(jie)合(he)的壓縮比大于冷壓結(jie)合(he)。建筑(zhu)膠(jiao)合(he)板(ban)(ban)是由縱橫交錯的單(dan)板(ban)(ban)制成(cheng)的，所(suo)以導熱系數比同(tong)類木(mu)(mu)(mu)材低。

建筑(zhu)膠(jiao)(jiao)合(he)(he)板(ban)(ban)單位壓力越高，建筑(zhu)膠(jiao)(jiao)合(he)(he)板(ban)(ban)的密度(du)越高。由于(yu)木材在(zai)高溫下容易發生塑(su)性變形(xing)，熱壓結合(he)(he)的壓縮比大(da)于(yu)冷壓結合(he)(he)。建筑(zhu)膠(jiao)(jiao)合(he)(he)板(ban)(ban)由交錯排列的單板(ban)(ban)制(zhi)成。其導熱系數低于(yu)同種類木材。建筑(zhu)膠(jiao)(jiao)合(he)(he)板(ban)(ban)的最(zui)外層單板(ban)(ban)叫(jiao)面板(ban)(ban)，正面板(ban)(ban)叫(jiao)面板(ban)(ban)，反面板(ban)(ban)叫(jiao)背板(ban)(ban)，內層單板(ban)(ban)叫(jiao)芯板(ban)(ban)或中板(ban)(ban)。
