钢筋混凝土现浇板的表面积较其他构件大,本身厚度较薄,在浇筑和养护中受外界影响时,如模板变形、施工荷载集中、顶柱不均匀下陷和气温、风向、湿度等的变化,容易出现裂缝。现介绍几起比较典型的工程实例。一、双向板裂缝某办公楼采用了双向板,见图1,抹地面
The surface area of the reinforced concrete cast-in-situ concrete slab is larger than other components, and the thickness of the reinforced concrete cast-in-situ concrete slab is relatively thin. When the concrete is affected by the outside during pouring and curing, such as deformation of the formwork, concentration of construction load, uneven subsidence of the top pillar, changes of temperature, Prone to cracks. Now introduce a few more typical examples of the project. First, the two-way plate crack Office building using a two-way plate, see Figure 1, wiping the ground
