The design of the indoor staircase step size must meet the needs of the home and the convenience of walking, and it must also have a more atmospheric visual experience. So what is the appropriate size of the villa stair step? As the size and shape of each villa are different, the size of the stairs in the villa is also different.
What is the size of the stairs in the villa?
1. When choosing the step size, not only the aesthetics of its appearance must be considered, but safety is the most important. To avoid large gaps and sharp edges and corners in the size design.
2. There are strict and precise requirements on the size of villa stairs:
Under normal circumstances, the size of the stairs is 900mm, and a platform must be installed at 18 steps. The step height is generally 170mm. The vertical distance from the first step to the top step of the villa’s staircase should be greater than 220mm. 2000mm, so that it will not produce a sense of depression, the height of the handrails on both sides of the stairs is: 850-900mm, and the best diameter is 550mm.
Villa staircase step size: width
The step width is also very important in the choice of villa staircase step size, and it must be strictly and accurately controlled and planned. The choice of villa staircase step size must also be magnificent and beautiful, and the width of the villa staircase step is naturally wider than the width of the commercial house staircase. Generally: 1m-1.2m, this width not only looks magnificent in visual effects but also considers the handling of large pieces of furniture. Of course, there are also some personalized alternative designs. The size and width of villa stairs are different.
Villa staircase step size: spiral staircase
The spiral staircase is a common decoration method for villa stairs:
1. The spiral staircase is usually arranged in a circle around a single column. The platform and steps are fan-shaped. The inner width of the staircase steps is small, forming a steeper slope, and the spiral staircase structure is more complicated.
2. The spiral staircase saves more space in use. The minimum step size of the villa staircase can be opened to 1300*1300mm or 1400*1100mm.
3. However, because the spiral staircase has only one stress point, it has certain defects in structure and load-bearing.
Villa stairs step size: slope
Villa staircase step size is very closely related to staircase design, but the villa staircase step gradient also plays an important role in the choice of villa staircase step size.
Many factors such as walking comfort, climbing efficiency, and space status should be considered in the choice of villa staircase step gradient.
The angle between the slope line and the horizontal plane is the stair slope. The villa stair step gradient is generally 20 degrees -45 degrees, and the best villa stair step gradient is about 30 degrees.
Due to the different styles and designs of the stairs, the requirements for the slope of the stairs are also different. If there are elderly or children in the family, it is recommended that the slope of the villa’s stairs is between 14 degrees and 27 degrees.
1. Ink line
The ink line is translated downward by 150 in the vertical direction, and the ink line is obtained. The distance between the ink line and the ink line in the vertical direction is the height of the step template (150). Play the cascade pattern board line. Use a spirit level. Divide the ink line or the ink line into nine equal parts (that is, the number of steps), and then draw the vertical line from each equal division point to obtain the template line of each step.
Second, play the vertical ink line
Play two vertical ink lines on the inner wall of the stair size beam; the spacing is the width of 9 steps; that is, 300×9=2700(). Also on the wall at the other end of the stair beam, two vertical ink lines were also flicked. Before erecting the upper stair template, the ink line, hammer ball, or theodolite should be used to guide the upper wall to the upper wall, so that the stair beam can be controlled up and down in a wide straight line to ensure that the step width is consistent.
Three, play diagonal ink line
First of all, the elevation of the intersection between the bottom of the slab and the beam of the stairs should be obtained. The slope of the stairs and the thickness of the slab should be used to find this elevation. Then find out the thickness of the junction between the ladder slab and the ladder beam;
Among them, the slope=150/300=0.5, the thickness of the ladder slab 1=80, and 2 can be simply calculated according to the ratio using the Pythagorean theorem, that is, the flat position of the bottom template of the ladder, and the elevation of the point is (1.48－0.15－0.089 )=1.241, the elevation of the point should be -(0.020+0.089)=-0.109. The connection is the ink line. Mark the calculated elevation on the laying-out plan for use during construction. Based on this, the required elevation of other stairs can be obtained;
Bounce oblique ink line: Measure up a step height (150) from the intersection of the horizontal line with an elevation of -0.02 and the ink line; get points. Connect the point with the intersection of the horizontal line with an elevation of 1.48 and the ink line, which is the ink line. The ink lines of the upper steps are also popped up.
