现在农村住宅盖楼房的越来越多,盖楼房需要楼梯。钢筋混凝土楼梯如何设计计算呢?应了解和掌握以下内容:一、楼梯的组成一般楼梯都是由楼梯段和休息平台所组成。楼梯段就是一根带有踏步板的、倾斜放置的梁(或板)。其倾斜坡度在20～45°之间,最适宜的坡度为30°左右。楼梯段宽度,在一般多层住宅中可用1.1～1.4米,最窄的不小于0.9米。楼梯段长度受踏步的连续级数控制,一般不超过18级,超过了应将楼梯段分成两段,中间设休息平台。一般踏步高度c为150～180毫米,踏步宽度a为240～300毫米。通常采
Now that more and more houses are being built in rural houses, the building needs stairs. How to design and calculate the reinforced concrete staircase? The following should be understood and mastered: First, the composition of the stairs The general staircase is composed of a staircase section and a rest platform. The stair section is an inclined beam (or board) with a step. Its slope is between 20 and 45 degrees, and the most suitable slope is about 30 degrees. The width of the stairway is 1.1 to 1.4 meters in a typical multi-storey house, and the narrowest is not less than 0.9 meters. The length of the stairway is controlled by the number of consecutive steps. Generally, the length of the stairway is not more than 18 steps. The stairway section is divided into two sections and a rest platform is set in the middle. The general step height c is 150 to 180 mm, and the step width a is 240 to 300 mm. Usually adopted
