摘要

建筑外幕墙就是建筑物不承重的外墙护围，通常由面板(玻璃、金属板、石板、陶瓷板等)和后面的支承结构(铝横梁立柱、钢结构、玻璃肋等等)组成。这样可以使建筑物从不同角度呈现出不同的美感。

近年来，建筑幕墙工程因质量差而造成国家财产损失及人身安全受到严重威胁的事件时有发生。如果加强对幕墙工程的管理，对其设计、施工技术、施工质量以及竣工验收进行有效的控制，并切实有效地进行建设监理制度，使得幕墙工程的质量能够得到保障。

本文针对建筑外幕墙工程施工和验收中发现的一些问题，重点关注施工过程和竣工验收过程，从具体的施工技术和验收规范谈谈自己对建筑外幕墙工程施工和验收的一点认识，更好地满足经济与社会可持续发展的要求，从而对建筑外幕墙工程建设产生积极地作用。
