輕質(zhì)復(fù)合墻板分復(fù)合墻板內(nèi)、復(fù)合墻板外墻兩種，目前以生產(chǎn)內(nèi)墻為主，內(nèi)墻厚有50mm、75mm、100mm 120mm 150mm五種規(guī)格。我們的墻板長(zhǎng)度有2440mm、3000mm兩種規(guī)格，寬度統(tǒng)一為610mm。厚度為50mm墻板主要用于商鋪，75mm墻板主要用于寫字樓及商住兩用樓，100mm墻板主要用于各種建筑的分戶墻。厚度為75mm內(nèi)墻與傳統(tǒng)120mm墻體加抹灰相比較,每建12沿長(zhǎng)米墻體可增加1平方米實(shí)用面積。房間整體面積增加率為4—6%。也就是說100平方米住宅就可增加4.26平方米的使用面積。

Light composite wallboard can be divided into composite wallboard inner wall and composite wallboard outer wall. At present, the production of inner wall is mainly used. The thickness of inner wall has five specifications: 50mm, 75mm, 100mm, 120mm and 150mm. Our wallboard has two specifications: 2440mm and 3000mm in length and 610mm in width. 50mm thick wallboard is mainly used for shops, 75mm wallboard is mainly used for office buildings and commercial and residential buildings, and 100mm wallboard is mainly used for household walls of various buildings. Compared with the traditional 120mm wall with plastering, the 75mm thick inner wall can increase the practical area of 1 square meter for each 12 meter long wall. The increase rate of the overall area of the room is 4-6%. In other words, 100 square meters of residence can increase the use area of 4.26 square meters.

由于復(fù)合墻板的水灰比較大，后期的失水干縮也較大。這會(huì)造成兩種現(xiàn)澆工程質(zhì)量事故。一種是，當(dāng)采用纖維水泥面板時(shí)，會(huì)因?yàn)楹笃跐{體的硬化干縮，使泡沫混凝土與面板分離，出現(xiàn)墻體空鼓，敲擊時(shí)墻體發(fā)空。

Due to the large water cement ratio of composite wallboard, the water loss and drying shrinkage in the later stage are also large. This will cause two kinds of quality accidents of cast-in-situ engineering. One is that when the fiber cement panel is used, the foam concrete will be separated from the panel due to the hardening and shrinkage of the slurry in the later stage, and the wall will be hollowed and the wall will be empty when knocking.

二種是，當(dāng)不使用纖維水泥面板而采用模板澆注時(shí)，模板拆除后，復(fù)合墻板會(huì)隨著泡沫混凝土的干縮而逐漸出現(xiàn)開裂。近年，有不少企業(yè)因上述質(zhì)量問題而被罰款或返工。目前，我們已在工程實(shí)踐中總結(jié)經(jīng)驗(yàn)，通過技術(shù)創(chuàng)新解決了空鼓、干縮 問題。

The two is that when the fiber cement panel is not used and the template is poured, the composite wallboard will gradually crack with the drying shrinkage of the foam concrete after the template is removed. In recent years, many enterprises have been fined or reworked for the above quality problems. At present, we have summed up experience in engineering practice and solved the problems of hollowing and drying shrinkage through technological innovation.

必須確保其符合玻纖含量。玻纖在商品中的效果與鋼筋在鋼筋混凝土中的效果是相同的，缺乏像缺乏相同的鋼筋玻璃的內(nèi)容，不能達(dá)到增強(qiáng)的效果。如果不添加玻璃纖維，拉伸和水泥基產(chǎn)品的抗彎強(qiáng)度小于2兆帕，抗彎強(qiáng)度和商品腳玻璃含量可達(dá)6MPa。商品修建裝修構(gòu)件在使用進(jìn)程中至少接受5種荷載(自重、風(fēng)，地震，溫度應(yīng)力，干濕變型應(yīng)力和其他外荷載)效應(yīng)，如果達(dá)不到強(qiáng)度目標(biāo)，將是非常不安全的。

It must be ensured that it meets the glass fiber content. The effect of glass fiber in commodity is the same as that of steel bar in reinforced concrete. Without the same content of steel bar and glass, the effect of reinforcement cannot be achieved. If glass fiber is not added, the flexural strength of tensile and cement-based products is less than 2 MPa, and the flexural strength and commercial foot glass content can reach 6 MPa. The commercial construction and decoration components will accept at least five kinds of load effects (self weight, wind, earthquake, temperature stress, dry and wet deformation stress and other external loads) in the process of use. If the strength target is not reached, it will be very unsafe.

復(fù)合墻板節(jié)省使用面積。安裝隔墻板后，整個(gè)房屋的使用面積將會(huì)有所減少，因此我們?cè)谶x擇隔墻板時(shí)好優(yōu)先考慮那些厚度小，強(qiáng)度高的板材，將使用面積的減少降低到低程度。例如在近幾年濟(jì)南舊房改造工程中，濟(jì)南墻板市場(chǎng)上輕質(zhì)夾芯隔墻板就被經(jīng)常采用。復(fù)合墻板有較高的強(qiáng)度。墻板強(qiáng)度高，抗沖擊，不易破損是隔墻材料的重要指標(biāo)。這一點(diǎn)，石膏板就存在明顯的不足，凡是石膏板隔墻，時(shí)間一久沒有不出現(xiàn)破損的，無法作為長(zhǎng)久性隔墻使用。

Composite wallboard saves use area. After installing the partition board, the use area of the whole house will be reduced. Therefore, when selecting the partition board, we should give priority to those plates with small thickness and high strength, so as to reduce the use area to a low degree. For example, in the reconstruction of old houses in Jinan in recent years, light sandwich partition boards are often used in Jinan wallboard Market. Composite wallboard has high strength. Wallboard has high strength, impact resistance and is not easy to be damaged. It is an important index of partition material. In this regard, gypsum board has obvious shortcomings. All gypsum board partitions that have not been damaged for a long time cannot be used as long-term partitions.

復(fù)合墻板在原有隔墻板價(jià)格基礎(chǔ)上要稍貴些許，因?yàn)樾滦蛷?fù)合隔墻板表面的硅酸鈣板不僅具有其他隔墻板產(chǎn)品不具備的良好隔聲功能，同時(shí)還具有十分優(yōu)越的防火隔熱性能，1000攝氏度高溫下，耐火極限超過3小時(shí)，而且不會(huì)散發(fā)任何有毒有害物質(zhì)。在選用復(fù)合墻板前，深入各板材生產(chǎn)企業(yè)進(jìn)行考察，了解其生產(chǎn)工藝、質(zhì)量體系、材料臨時(shí)堆放場(chǎng)地、企業(yè)生產(chǎn)能力，以板材各項(xiàng)指標(biāo)都符合標(biāo)準(zhǔn)、有足夠的板材晾曬時(shí)間、材料的干燥。要求板材生產(chǎn)企業(yè)在生產(chǎn)過程中采用專用的水性隔離劑而不要采用廢機(jī)油。

The composite wallboard is slightly more expensive than the original partition board price, because the calcium silicate board on the surface of the new composite partition board not only has the good sound insulation function that other partition board products do not have, but also has very superior fire and heat insulation performance. Under the high temperature of 1000 ℃, the fire resistance limit exceeds 3 hours, and will not emit any toxic and harmful substances. Before selecting composite wallboard, go deep into each plate production enterprise to investigate its production process, quality system, temporary material stacking site and enterprise production capacity, so as to ensure that all indexes of the plate meet the standards, have sufficient plate drying time and material drying. Plate manufacturers are required to use special water-based isolating agent instead of waste engine oil in the production process.
