    防火板面板為什么會裂?

    來源:http://www.kcrft.cn/ 日期:2023-01-16 發(fā)布人:admin
    防火板是一種防火建筑材料,一般作為飾面使用。那么防火板開裂如何修復(fù)呢?首先要知道防火板為什么會裂開,然后根據(jù)原因進(jìn)行解決,下面一起來詳細(xì)了解一下防火板開裂修復(fù)的相關(guān)內(nèi)容吧。
    Fireproof board is a fire-proof building material, which is generally used as a decoration. So how to repair the crack of the fireproof board? First of all, we need to know why the fireproof board cracks, and then solve the problem according to the reason. Now let's have a detailed understanding of the relevant contents of the repair of the fireproof board cracks.
    材料原因
    Material reason
    骨架材料:骨架材料包括龍骨和其他配件。如果骨架材料質(zhì)量達(dá)不到要求,將直接影響整個骨架牢固程度,是產(chǎn)生板縫開裂和變形的重要原因。
    Skeleton materials: Skeleton materials include keels and other accessories. If the quality of the skeleton material does not meet the requirements, it will directly affect the firmness of the whole skeleton, which is an important reason for the crack and deformation of the plate joint.
    板材質(zhì)量:防火板板材作為覆面材料,是靠高強(qiáng)自攻螺釘與輕鋼龍骨緊密地固定在一起的,如果板材達(dá)不到質(zhì)量要求,板和龍骨之間就不能牢固地固定,當(dāng)有外力作用時,板接縫處會產(chǎn)生剪切力,導(dǎo)致板接縫開裂。
    Plate quality: As the covering material, the fireproof plate is tightly fixed with high-strength self-tapping screws and light steel keel. If the plate fails to meet the quality requirements, the plate and keel cannot be firmly fixed. When there is external force, the shear force will be generated at the plate joint, resulting in the plate joint cracking.
    嵌縫材料:嵌縫膩?zhàn)硬坏缶哂泻芎玫膹?qiáng)度、粘結(jié)性,而且還要有一定的韌性和好的施工性能。如果都達(dá)不到以上性能,不可避免地要產(chǎn)生裂縫。
    Caulking material: Caulking putty shall not only have good strength and adhesion, but also have certain toughness and good construction performance. If the above performance is not achieved, cracks will inevitably occur.

    施工原因
    Construction reasons
    施工工藝不規(guī)范,不按設(shè)計要求施工不按操作規(guī)程施工,板與板接口處不按要求留縫,大面積施工鋪板未錯縫,緊固螺釘短小或布點(diǎn)稀疏,嵌縫膩?zhàn)幽z量不足或過軟,平縫、陰角、陽角不按規(guī)定貼帶或包角等。都將會降低骨架整體的剛度和牢固度,產(chǎn)生內(nèi)應(yīng)力,引起變形甚至造成接縫開裂。
    The construction process is not standardized, the construction is not carried out according to the design requirements, the construction is not carried out according to the operating procedures, the joints between the plates are not left according to the requirements, the large area of construction planking is not staggered, the fastening screws are short or sparse, the amount of caulking putty is insufficient or too soft, and the flat joints, internal corners and external corners are not taped or wrapped as required. Will reduce the overall stiffness and firmness of the skeleton, produce internal stress, cause deformation and even cause joint cracking.
    人為因素
    human factor
    施工單位在追求大利益的思想驅(qū)使下,擅自降低質(zhì)量要求,在施工材料上做手腳,以小充大、以薄充厚、以假充真、以次充好。
    Driven by the idea of pursuing great interests, the construction unit arbitrarily reduces the quality requirements and manipulates the construction materials to replace the small with the large, the thin with the thick, the fake with the real, and the inferior with the good.
    通常施工是在自然環(huán)境下進(jìn)行的,而一年四季中室內(nèi)外的溫度和濕度都不可能是一恒定值。特別是在室內(nèi)空調(diào)、暖氣等負(fù)面效應(yīng)的影響下,空氣濕度降低,這種狀況與當(dāng)初的施工條件相比環(huán)境條件異變較大,鎂晶板中原有的溫濕平衡被破壞,板面干縮,出現(xiàn)裂縫。您有什么問題就來我們網(wǎng)站http://www.kcrft.cn咨詢吧!
    Generally, the construction is carried out in the natural environment, and the indoor and outdoor temperature and humidity cannot be a constant value throughout the year. Especially under the influence of indoor air conditioning, heating and other negative effects, the air humidity is reduced, which is greatly different from the original construction conditions. The original temperature and humidity balance in the magnesium crystal board is damaged, the board surface is dried and cracks appear.
