In order to scientific control engineering cost to attain efficiency purpose,aimed at the waste of social resources by traditional horse stool style spacer bar,we designed a new type has the advantages of multifunctional recycled through the repeated design and theoretical calculation. During the engineering trial the concrete slab which was built with the new kind horse stool style spacer bar has been tested up to the national regulation,which could provide reference for other projects..%为了科学控制工程成本，达到降本增效目的，针对传统马凳筋对社会资源的浪费现象，通过反复设计和理论计算，设计出了一种新型马凳，该马凳具有多功能可循环使用的优点。在工程的试用中，通过实验检测，使用了该马凳筋浇筑的混凝土板各方面质量均符合国家验收规范要求，可为其他项目提供借鉴。
