建筑幕墙基于四性检测的施工质量关键问题研究

Research on Construction Quality Issues of Curtain Wall Based on Four Physical Properties Testing

建筑幕墙的性能主要分为两大类:一是力学性能,涉及幕墙的安全性与可靠性;二是物理性能,涉及幕墙的适用性和节能性。幕墙性能检测一般在工程设计完成后,幕墙组件批量生产、加工和安装施工前进行。本文重点阐述了建筑幕墙气密、水密、抗风压及层间变形性能检测的关键步骤。同时结合自身工作经验,对多个幕墙项目的检测结果进行统计分析,总结了幕墙性能检测结果不合格的主要影响因素,涉及设计、材料加工、安装工艺等方面。最后提出合理化处理建议,为幕墙施工过程中的质量管控提供一定参考依据。

The performance of building curtain wall can be mainly divided into two categories:mechanical performance,which involves the safety and reliability of the curtain wall,and physical performance,which involves the applicability and energy efficiency of the curtain wall.The performance testing of curtain wall is generally carried out after the completion of engineering design and before the mass production,processing,and installation of curtain wall components.This article elaborates on the key steps for testing the air permeability performance,watertightness performance,wind load resistance performance,and inter story deformation performance of building curtain walls.At the same time,based on my own work experience,I conducted statistical analysis on the testing results of multiple curtain wall projects,and summarized the factors affecting the unqualified physical performance testing results of curtain walls,mainly involving design,material processing,installation technology,and other aspects.Finally,reasonable treatment suggestions are proposed to provide a certain reference basis for quality control during the curtain wall construction process.
