金属板幕墙工程设计和施工质量过程控制

及应用

Metal plate curtain wall engineering design and construction quality process

control and Application

跟着近三十年来我国幕墙职业的开展,近几年金属板幕墙在各大中城市修建的选用现已适当遍及,但存在的疑问也不少。建设部于2001年公布的《金属与石材幕墙工程技术标准》(JGJ 133——2001)作为职业标准。但因为一些种种原因,在实践的工程描绘和施工中,有些疑问应然存在。下面经过自己的工程实践中,就有关一些疑问进行评论。

With the development of China"s curtain wall occupation in recent thirty years, selection has in recent years metal plate curtain wall construction in the major city proper throughout, but there are also a lot of questions. Ministry of Construction announced in 2001 the \and stone curtain wall engineering technical standards\(JGJ 133 -- 2001) as the occupation standard. But because of some reasons, in the practice of engineering drawing and construction, there ought to be some doubt. The following after own engineering practice, the relevant questions for review.

金属板幕墙按面材分类包含铝单板幕墙.铝复合板幕墙.蜂窝铝

板幕墙.彩色钢板幕墙.珐琅钢板幕墙.不锈钢板幕墙.钛合金板幕墙等,其根本描绘布局及设备技术根本迥然不同。金属板幕墙描绘包含修建描绘和布局描绘两大有些,关于金属板幕墙的防火.防雷,墙体保温.衔接预埋件的布局安全.反正框龙骨的布局受力需求满意等方面描绘的好坏,将直接影响到整栋修建的安全与外形的漂亮及舒服程度。

Classification of metal plate curtain wall according to the surface material contains a single aluminum plate curtain wall. Aluminum posite panel curtain wall. The honeyb aluminum curtain wall. Color steel plate curtain wall. Enamel plate curtain wall. Stainless steel plate curtain wall. The titanium alloy plate curtain wall, the picture layout and equipment technology could be totally different. Metal plate curtain wall construction and layout description contains picture depicting two some, fire on the metal plate curtain wall. Lightning protection, wall insulation. Layout safe connection of embedded parts, frame keel layout force demand satisfaction, paint is good or bad, will directly affect the whole building safety and appearance of the beautiful and fortable degree. 金属板幕墙防火描绘首要应思考两个部位,其一是金属板幕墙的窗间墙,其二是金属板幕墙与每层楼板.隔墙处的缝隙。标准规则,金属板幕墙窗间墙的填充资料应选用不焚烧资料。因而,既能满意运

用功用需求,又能确保满意防火需求。首要,是在每层楼板外沿,设置耐火极限不低于一个小时,高度不低于800mm的不焚烧实体裙墙,或在布局描绘上处置成同高度的混凝土梁或包侧板。

Metal plate curtain wall painted first, thinking of two parts, one is the metal plate curtain wall between windows, the metal plate curtain wall and each floor cracks at the wall. Rules for filling materials, metal plate curtain wall between windows should be used not burned data. Thus, not only can use function requirement, and can ensure the satisfaction of fire. First, it is in every floor edge, set the fire resistance limit of not less than one hour, the height is not less than 800mm is not burning solid skirt wall, or in the layout drawing disposal into with the height of the concrete beam or plate. 金属板幕墙与每层楼板之间都应有100mm~200mm的缝隙,此处是蹿火通道,有必要用不焚烧资料填充,金属板幕墙与窗间隔墙之间的缝隙应照此处处置。金属板幕墙围护高层修建后,修建物的原防雷设备因为幕墙的屏蔽效应不能直接起到防雷效果,而变得闪电对幕墙的雷击。幕墙的金属资料因为雷电效应将会发生强壮的静电感应电压,对室内的人和设备都会构成损害。因而在描绘时,依据修建物防雷等级,一方面应使幕墙构成本身的防雷系统,另一方面应与主体布局的防雷系统可靠地衔接。

The gap between the metal plate curtain wall and each floor

should be 100mm~200mm, here is the fire channel, it is necessary to fill in data gaps between not burning, metal plate curtain wall between the window and the wall should be here to disposal. Metal plate curtain wall high-rise building, the building of the original lightning protection equipment for the shielding curtain wall can not directly to the effect of lightning protection, lightning strikes and bee for curtain wall. Metal material curtain wall because of electrostatic induction voltage lightning effects will be strong, on the interior of the people and equipment will be damage. Thus in the description, on the basis of building lightning protection level, one should make curtain wall posed of lightning protection system itself, on the other hand, lightning protection system and the main layout and reliable convergence.

金属板幕墙的防雷设备与修建物的防雷网接通方法:一是在钢筋混凝土墙上经过柱或墙内的主钢筋设置预埋衔接板和引出衔接板作为供测验盒衔接用;二是在使用金属板幕墙预埋件与主体防雷网接通;三是在立桩.复合土工膜梁墙混凝土浇筑之前加焊一段预埋留接线引出,作为衔接通道。为削减防雷空间的火灾.爆破及生命危险,实木复合门金属板幕墙的防雷应采纳等电位衔接,以削减雷电流导致的电位差。

and building lightning protection network switching method: one is the reinforced concrete wall by the main reinforced columns or walls arranged embedded connecting plate and the connecting plate as a test case leads to convergence; two is the use of metal plate curtain wall embedded parts and the main lightning protection network connection; three is at stake beam wall. Before concrete pouring welding a pre-embedded stay wire lead-out, as the connection channel. To reduce lightning space. The blasting and fire danger, lightning protection of metal plate curtain wall should adopt equipotential connection, potential leads to the reduction of lightning current difference.
