摘要
为优化建筑用压型钢板外墙的力学性能,制备系列试样,用压型钢板作为主要结构材料,通过裁剪和焊接构建外墙板腔体,并在腔体内灌注混凝土,最后焊接顶板完成墙体组装。通过调整钢板厚度、混凝土强度、外墙板厚度及有无肋板制备等参数,探讨不同参数对墙体承载力和稳定性的影响。结果表明:钢板厚度与墙体承载力正相关,但厚度超过12 mm后,材料成本显著增加,因此,12 mm为最优钢板厚度。混凝土强度对整体承载力的影响相对有限,40 MPa即可满足设计要求,且具有较好的经济性。墙体厚度为17 cm时,在保证抗拉性能的同时,可实现性能与成本的平衡。加装肋板可显著提升外墙板的抗压强度,建议在实际工程中用12 mm钢板厚度、40 MPa混凝土强度、17 cm墙体厚度并加装肋板的优化方案,该配置可在保证结构性能的同时实现最佳经济效益。
To optimize the mechanical properties of profiled steel sheet exterior walls used in buildings,a series of samples were prepared.Profiled steel sheets were used as the main structural materials.The exterior wall panel cavities were constructed through cutting and welding,and concrete was poured into the cavities.Finally,the top plate was welded to complete the wall assembly.By adjusting parameters such as the thickness of steel plates,the strength of concrete,the thickness of exterior wall panels and the preparation of ribbed plates,the influences of different parameters on the bearing capacity and stability of the wall were explored.The results show that the thickness of the steel plate is positively correlated with the bearing capacity of the wall.However,when the thickness exceeds 12 mm,the material cost increases significantly.Therefore,12 mm is the optimal thickness of the steel plate.The influence of concrete strength on the overall bearing capacity is relatively limited.A grade of 40 MPa can meet the design requirements and has good economy.When the thickness of the wall is 17 cm,a balance between performance and cost can be achieved while ensuring the tensile performance.The installation of ribbed plates can significantly enhance the compressive strength of the exterior wall panels.It is recommended to adopt an optimized scheme with a steel plate thickness of 12 mm,a concrete strength of 40 MPa,a wall thickness of 17 cm,and the addition of ribbed plates in actual projects.This configuration can achieve the best economic benefits while ensuring structural performance.
