摘要:
石膏基复式榫槽轻质模块装配式墙体作为建筑内隔墙体工程的一种新的技术型式,是促进内隔墙体多元化发展、装配式建筑推广及内隔墙工程质量提高的重要手段和途径。文章通过胶凝材料改性、模块构造型式设计,实现了轻质模块纵横四面双向定位方法拼装,研究了轻质模块力学性能和机理,并对拼装后墙体整体稳定性进行了试验研究和有限元模拟分析。结果表明:轻质模块的胶凝材料改性,提高了石膏硬化体密实度,改善了复式榫槽轻质模块的力学强度和耐水性能,轻质模块干密度约为560和645 kg/m3时,其抗压强度分别增加了45.8%和31.0%,抗折强度分别增加了43.7%和48.5%;轻质模块装配式墙体抗冲击性能良好,采用专用粘结胶浆嵌缝拼装的墙体较直接干法拼装墙体抗冲击次数提高57%,榫槽咬合拼装后墙体受冲击破坏规律与传统砌筑墙体相似,整体稳定可靠。
Abstract:
As a new technical type of building interior partition wall engineering, the gypsum base composite tenon groove lightweight modular fabricated interior partition wall is an important means and way to promote the diversified development of interior partition wall and the popularization of assembly building and improve the quality of interior partition wall engineering. Through the modification of the cementitious material and the design of the structural module, the paper completed the assembling of the four side and horizontal positioning method of the light weight module, studied the mechanical properties and the mechanism of the light weight module, and carried out the experimental study and the finite element simulation analysis on the whole stability of the wall after the assembly. The results show that the modification of the cementitious material of the light weight module improves the density of the plaster hardenite, and improves the mechanical strength and water resistance of the compound tongueandgroove light weight module. When the dry density of the light weight module is about 560 kg/m3, the compressive strength and flexural strength increase by 45.8% and 43.7% respectively. When the dry density is about 645 kg/m3, the compressive strength and flexural strength increase by 31.0% and 48.5% respectively. The impact resistance of the lightweight module assembly wall is good, and the impact times of the wall mounted by the special adhesive mortar increase by more than 57%. The impact failure of the wall is similar to that of the traditional masonry wall, and the overall stability is stable and reliable.
