Combined structure of staircase and exhaust shaft
The staircase and exhaust shaft combined structure comprises a staircase and an exhaust shaft which are adjacently arranged, one end of the staircase and one end of the exhaust shaft both extend to an underground space, and the other end of the staircase and the other end of the exhaust shaft both extend to an overground space; a staircase emergency door is arranged on one side of the staircase located in the overground space, and an inner concave part is arranged at the top of the staircase; the exhaust shaft comprises a first exhaust chamber and a second exhaust chamber which are communicated with each other, the second exhaust chamber is located in the inner concave part, the first exhaust chamber and the staircase are separated through a first baffle, the first exhaust chamber and the second exhaust chamber are separated through a second baffle, and the second baffle is located above the first baffle. The second baffle is provided with a ventilation opening communicated with the first exhaust chamber and the second exhaust chamber, an exhaust opening is formed in the top of the second exhaust chamber, a metal grating is installed at the exhaust opening, and a drainage mechanism is arranged in the second exhaust chamber. The staircase and the exhaust shaft are integrally designed, drainage is facilitated, and arrangement of a sump and a drainage pump in a basement is avoided.
本发明公开了一种楼梯间与排风井的组合结构，包括相邻设置的楼梯间和排风井，楼梯间和排风井的一端均延伸到地下空间，另一端均延伸到地上空间；位于地上空间的楼梯间的一侧设有楼梯疏散门，楼梯间的顶部设有内凹部；排风井包括相连通的第一排风室和第二排风室，第二排风室位于内凹部，第一排风室与楼梯间之间通过第一挡板进行分隔，第一排风室和第二排风室之间通过第二挡板进行分隔，第二挡板位于第一挡板的上方，第二挡板设有连通第一排风室和第二排风室的通风口，第二排风室的顶部设有排风口，排风口处安装有金属格栅，第二排风室内设有排水机构。本发明将楼梯间和排风井进行整合设计，且便于排水，避免了在地下室设置集水坑和排水泵。
