一、工程简介和漏水情况 该工程为一次设计分期施工,建筑面积3900m~2,四层全框架结构,局部五层。一、二层营业,三、四层办公,五层是会议厅。一期工程约1100m~2,1987年竣工;二期工程约2800m~2,1988年竣工。一期工程没有漏水,二期工程却漏水严重,漏水部位不在屋面,而在下部楼层(图1)。图1为三层漏水的情况,从图1可以明显看出,漏水部位多出现在北向和西向房间,而南向和东向房间漏水较少。
I. Project Introduction and Water Leakage This project is a one-stage construction project with a construction area of 3900m2, a four-story full-frame structure, and a local five-story structure. The first and second floor are open for business, and the third and fourth floors are offices. The fifth floor is the conference hall. The first phase of the project was about 1100m 2 and was completed in 1987; the second phase was about 2800m 2 and was completed in 1988. There was no water leakage in the first phase of the project, but there was serious leakage in the second phase of the project. The leakage was not on the roof but on the lower floor (Figure 1). Figure 1 shows the situation of water leakage in the third floor. It can be clearly seen from Figure 1 that leaking parts mostly appear in the north and west rooms, while the south and east rooms have less water leakage.
