摘要
现浇板类构件的钢筋保护层厚度是影响其承受结构荷载及使用年限的重要指标,常用的控制方法一般采用在受力钢筋上绑扎砂浆(混凝土)垫块、橡胶垫块,以及投入大量支撑受力钢筋的措施筋,这些方法存在强度不足、容易破损位移、踩踏后主筋下沉等技术缺陷,且不可周转使用,一次性消耗的成本不容小视.本文针对传统工艺的弊端,创新研发可标准化生产、能周转通用的钢筋保护层控制工具,促进钢筋隐蔽工程的标准化施工与管理,消除现浇板类构件的质量通病,同时简化施工工序,降低高额措施费,实现节材创效.
Abstract
The thickness of the steel reinforcement protection layer for cast-in-place slab components is an important indicator affecting their structural load and service life.The commonly used control methods generally include tying mortar(concrete)cushion blocks and rubber cushion blocks on the load-bearing steel bars,as well as investing a large amount of measure reinforcement to support the load-bearing steel bars.There are technical defects such as insufficient strength,easy damage displacement,and sinking of the main reinforcement after stepping,and they are not reusable,resulting in significant one-time consumption costs.This article focuses on the drawbacks of traditional craftsmanship and innovatively develops a standardized production and turnover universal steel reinforcement protection layer control tool to promote standardized construction and management of steel reinforcement concealed engineering,eliminate common quality problems in cast-in-place slab components,simplify construction processes,reduce high construction costs,and achieve material saving and efficiency creation.
