    防火板面板为什么会裂?

    来源:/ 日期:2023-01-16 发布人:fumeijia
    防火板是一种防火建筑材料,一般作为饰面使用。那么防火板开裂如何修复呢?首先要知道防火板为什么会裂开,然后根据原因进行解决,下面一起来详细了解一下防火板开裂修复的相关内容吧。
    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:骨架材料包括龙骨和其他配件。如果骨架材料质量达不到要求,将直接影响整个骨架牢固程度,是产生板缝开裂和变形的重要原因。
    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.
    板材质量:防火板板材作为覆面材料,是靠高强自攻螺钉与轻钢龙骨紧密地固定在一起的,如果板材达不到质量要求,板和龙骨之间就不能牢固地固定,当有外力作用时,板接缝处会产生剪切力,导致板接缝开裂。
    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.
    嵌缝材料:嵌缝腻子不但要求具有很好的强度、粘结性,而且还要有一定的韧性和好的施工性能。如果都达不到以上性能,不可避免地要产生裂缝。
    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
    施工工艺不规范,不按设计要求施工不按操作规程施工,板与板接口处不按要求留缝,大面积施工铺板未错缝,紧固螺钉短小或布点稀疏,嵌缝腻子胶量不足或过软,平缝、阴角、阳角不按规定贴带或包角等。都将会降低骨架整体的刚度和牢固度,产生内应力,引起变形甚至造成接缝开裂。
    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.
    人为因素
    human factor
    施工单位在追求大利益的思想驱使下,擅自降低质量要求,在施工材料上做手脚,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.
    通常施工是在自然环境下进行的,而一年四季中室内外的温度和湿度都不可能是一恒定值。特别是在室内空调、暖气等负面效应的影响下,空气湿度降低,这种状况与当初的施工条件相比环境条件异变较大,镁晶板中原有的温湿平衡被破坏,板面干缩,出现裂缝。您有什么问题就来我们网站咨询吧!
    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. Come to our website if you have any questions Ask!
