建筑施工中由于受施工条件的限制,很多情况下混凝土的浇筑要留置施工缝。基础工程也同样存在这种问题。本文就基础混凝土施工中留置施工缝的问题进行探讨。 1.如图1所示单独现浇柱基础,若按《钢筋混凝土工程施工及验收规范》(GBJ204—83)(以下简称《规范》)第4.4.17条的要求只在1-1剖面处留置施工缝,现场基坑的夯填工作在上部结构拆模前一般是无法全部完成的。因此,往往造成柱、梁、板的模板安装困难。模板安装的刚度、
Due to the restrictions of construction conditions in the construction of the building, in many cases, the construction of the concrete shall be placed in the construction joints. Basic engineering also has this problem. This article discusses the problem of retaining construction joints in the foundation concrete construction. 1. As shown in Fig. 1, the individual cast-in-situ pillar foundations are only in the section 1-1 if they are in accordance with the requirements of Section 4.4.17 of the “Code for the Construction and Acceptance of Reinforced Concrete Construction” (GBJ204-83) (hereinafter referred to as “the Code”). In order to retain the construction joints, the filling of the foundation pits is generally not completed before the upper structure is demolished. Therefore, the installation of the formwork of columns, beams, and plates is often difficult. The rigidity of the template installation,
