摘　　要：本文旨在论述岭南地区博物馆应用新型透光混凝土墙板的相关施工工艺,通过材料实验分析和总结透光混凝土的透光性能、抗压强度、抗渗透性等技术指标,并探究透光混凝土墙板干挂安装机构和施工工艺,提高干挂透光混凝土墙板的施工效率和效果,并减少安装机构对光源的干涉和不利影响。最后通过DEST等节能软件模拟分析、试验和监测博物馆内外光源效果,探索智能化的监测光源方法。通过一系列模拟分析和试验研究,为保证博物馆外立面墙板强度,导光体材料体积比需保证不超过3%。同时,墙板固定装置与导光体位置协调,使用BIM软件建模模拟“碰撞”,防止重叠干涉,保证透光率达到设计要求。透光混凝土需做好导光体和混凝土的接触界面处理,平衡整体力学性能和透光率的取舍,导光体数量增加会导致接触界面增加,会减弱混凝土的内部强度和耐久性能。This article aims to discuss the relevant construction techniques for the application of new transparent concrete wall panels in museums in the Lingnan region.Through material experiments,the technical indicators of transparent concrete,such as transparency performance,compressive strength,and permeability resistance,are analyzed and summarized.The dry hanging installation mechanism and construction technology of transparent concrete wall panels are explored to improve the construction efficiency and effect of dry hanging transparent concrete wall panels,and reduce the interference and adverse effects of installation mechanisms on light sources.Finally,through energy-saving software such as DEST,simulation analysis,experimentation,and monitoring of the lighting effects inside and outside the museum were conducted to explore intelligent monitoring methods for lighting sources.Through a series of simulation analysis and experimental research,in order to ensure the strength of the exterior wall panels of the museum,the volume ratio of the light guide material needs to be ensured to not exceed 3%.At the same time,the fixing device of the wall panel needs to coordinate with the position of the light guide,use BIM software to model and simulate"collision",prevent overlapping interference,and ensure that the light transmittance meets the design requirements.Transparent concrete requires proper interface treatment between the light guide and the concrete,balancing the overall mechanical properties and transmittance.An increase in the number of light guide will lead to an increase in the contact interface,which will weaken the internal strength and durability of the concrete.
