选择合宜的大楼板,对于简化板柱体系框架轻板结构的施工工艺、减轻结构自重具有重要作用,1980年为配合某工程,我们进行了双钢筋复合大楼板的试验,现该工程已交付使用。实践表明,双钢筋复合大楼板不仅具有良好的技术经济指标,而且自重轻,施工工艺简单。下面分述大楼板的设计、生产和试验情况: 一、大楼板的设计和构造大楼板平面尺寸为3500×4400毫米,板厚165毫米,构造尺寸及配筋情况见图1。在板柱结构体系中,大楼板的受力状态
Choosing an appropriate building board has an important role to play in simplifying the construction technology of the light-plate structure of the board and column system and reducing the weight of the structure. In order to cooperate with a certain project in 1980, we conducted a test of a double-reinforced composite building board, and the project has now been put into use. . Practice has shown that the double-reinforced composite building panel not only has good technical and economic indicators, but also has a light weight and a simple construction process. The following describes the design, production, and test of the building panel: 1. The design and construction of the building panel The plane size of the building panel is 3500×4400mm, and the thickness is 165mm. The construction size and reinforcement are shown in Figure 1. In the pillar structure system, the stress state of the building board
