王建、刘锴、刘文康、徐长建、谢广田中建中新建设工程有限公司山东青岛266000摘要:叠拼建筑是由多层建筑中的一种,不同于普通的钢筋混凝土结构。
由于叠拼结构的特点,因此叠拼建筑在安全性、实用性以及经济性上有着较高的要求。
为了保证叠拼楼具有一定质量标准,需要对叠拼楼房的建筑模型、结构构件的制作质量等进行控制。
关键词:叠拼建筑;常见质量问题;控制方法由于国内外建筑市场快速发展,我国的建筑业已经逐渐进入到一个新时代。
面对日益激烈的市场竞争,为了满足市场需求和行业创新需要,政府对建筑业提出了更加严格的要求。
在此背景下,叠拼建筑作为一种新兴技术发展迅速,然而在实际操作过程中却面临着很多方面不能充分发挥技术优势,导致产品质量问题频发不能满足市场需求。
1.叠拼结构存在的质量问题1.1钢筋保护层厚度不足或钢筋数量不足由于叠拼楼楼板施工时会采用现浇楼板或预制梁施工工艺,所以可能会在现浇楼板时施工不符合设计要求或者钢筋数量不足等问题。
而此时,预制梁会成为现浇楼板施工质量缺陷的主要源头之一。
若预制梁不能达到设计要求时,就会导致楼板厚度不够,进而影响到建筑主体结构和抗震性能方面的安全性;若钢筋数量不足,就会导致现浇层没有足够的箍筋保护作用。
若预制梁出现问题不能很好地避免这些质量缺陷产生,最终会严重影响到建筑结构安全问题。
1.2现浇楼板施工质量问题现浇楼板结构在施工过程中主要有以下几种质量问题:(1)楼板与主体工程连接处的钢筋保护层厚度不足;(2)楼板与主体工程连接处的钢筋数量不足;(3)楼板与主体工程连接处的钢筋数量不足;(4)混凝土浇筑时水泥用量不足而不是使用同一种骨料,这是造成施工者没有在施工前对现浇层进行认真研究设计方案和施工规范,从而导致现浇楼板结构施工质量问题不断加重并最终导致质量事故的发生。
折叠家居可行性研究报告IntroductionThe concept of foldable furniture has gained popularity in recent years as people are seeking practical and space-saving solutions for their homes. The idea of furniture that can be easily folded and stored when not in use is appealing to many homeowners. This feasibility study aims to evaluate the viability of incorporating foldable furniture into homes and assess the potential benefits and challenges of implementing such a concept.BackgroundThe trend of living in smaller spaces, such as apartments and tiny houses, has driven the demand for compact and versatile furniture. Foldable furniture offers a solution to this growing need by providing flexible and adaptable options for optimizing living spaces. From foldable tables and chairs to murphy beds and modular storage units, there is a wide range of foldable furniture available on the market.
