All kinds of stairs

Q: Why is it only half that of the staircase section that is automatically generated by the building?: The problem is likely to be in your picture of the cut line, draw the tangent line to pay special attention to its implied view, such as [said from left to right.

Q: The stairs are said to be good? Do you know: Your website check to know, casually a search there.

Q: How do the staircase board be numbered?: Is the question in detail? Usually from the stairs to start the first step number first step second step ... ... if the floor can be a lot of the floor, such as: the first floor to the second floor of the first step to the fourth floor of the fifth step and so on The way to do this is to follow the signs on the floor plan so that the workers are easy to carry and install.

Q: Stairs detail: stepping wide, stepping high, stairs size for how much?: General staircase design reference size Name step high / mm stepping width / mm (Maximum value commonly used value minimum value commonly used value) Residential 175 150 ~ 175 260 260 ~ 300 Primary and secondary schools 150 120 ~ 150 260 260 ~ 300 Office buildings 160 140 ~ 160 280 280 ~ 340 Kindergarten 150 120 ~ 140 260 260 ~ 280 Nursing homes 150 300 Theater, Hall 160 130 ~ 150 280 300 ~ 350

Q: What are the requirements for staircase design in building seismic design codes?: 6.1.15 Stairwells shall meet the following requirements: 1 should use cast-in-place reinforced concrete stairs. 2 For the frame structure, the arrangement between the stairwells should not cause the structure plane to be particularly irregular; when the staircase components and the main structure are poured, the influence of the stair members on the seismic action and its effect should be included, and the seismic bearing capacity of the staircase components should be checked ; Should take structural measures to reduce the staircase components on the main structure of the impact of stiffness. 3 staircase between the two sides filled with walls and columns should be strengthened between the knot. Above it is multi-storey and high-rise concrete houses. 13.3.4 Masonry filled walls in reinforced concrete structures shall meet the following requirements: 5 staircase and the inflow channel filled with walls, should still be used to strengthen the steel mesh mortar surface.

Q: Staircase non-slip bar according to the length of the design requirements, such as the design of no provisions, according to the length of both sides of the total length of what calculation: Staircase non-slip bar according to the length of the design requirements, such as the design of no provisions, according to the length of both sides of the length of 15 cm calculation. Floor ground works Description First, mortar, stone pulp thickness, strength grade, the strength of concrete grade, design and fixed set different, you can convert. Second, the cushion project, such as for the base cushion, the artificial, mechanical multiplied by 1.20 (excluding full house basis). Third, the floor heating room cushion, according to different materials apply the corresponding quota, artificial multiplication coefficient 1.80, material multiplication coefficient 0.98. Fourth, the ground brush silicone slurry according to B.2 wall cylinder corresponding project calculation. Fifth, the stairs leveling layer by horizontal projection area multiplication factor 1.37, step multiplication factor 1.48. The thickness of the cement paste layer of each floor is increased by 1mm, and the corresponding artificial 0.276 working days, mortar 0.102m3 and mortar mixer (200L) are 0.012 classes per 100㎡. Seven, the overall surface layer, the block surface layer of the use of white cement, metal molding, paint, etc., such as design and project set different, you can adjust. 8, cement mortar ground pressure line, the per 100 ㎡ increase of 1.58 working days. Nine, block material surface cutting for the arc, shaped, parquet and slanting, according to the corresponding project manual multiplier 1.50, block material loss rate according to the actual adjustment. 10, tile ceramic tiles, such as the design of wave cable, the circumference ≦ 2400mm, the loss rate adjusted to 2.5%; circumference> 2400mm, the loss rate adjusted to 4%; wave line to implement sporadic projects.

Q: What is the role of a stairway in a building (a ladder next to a handrail)?: If there is no ladder, the end of the two ladder plates connected to the platform will be partially touched together, which will make the construction and installation of concrete in the concrete rather inconvenient. In addition, the staircase board phase, then, will also cause the side part of the railings and handrail distance is too close to pedestrian use. Some people may say that the railing inward to make a little, not on it? In fact, then the railing between the concrete slab is useless, it would not have it? There is also a possible cause, and the building modulus. The width of the stairs can be set, plus railings installation space, coupled with the distance between the railing, plus the outer wall, the total width should be about 2.8 meters, and apply the general building modulus, the general use of 3 meters, Out of about 20 centimeters, which may also be the reason for the existence of ladder.

Q: Why can not the evacuation door be on the stairs?: 3, the building in the closed staircase, smoke staircase, fire elevator front room and the former room, should not set the shutter doors.

Q: Today saw the 2013 residential design specifications. 3.8.4 The width of the staircase should not be less than 0.22m, the height should not be greater than 0.20m, fan-shaped stepping angle from the handrail 0.25m, the width should not be less than 0.22m. For the fan-shaped step angle from the handrail edge 0.25m, the width should not be less than 0.22m. I can not understand what kind of concept, it is best to mark out to show me thank you: that is, "people can use part of the width to ensure that 220 can"

Q: Dnf the stairs that have a successful task how to complete: DNF stairs is a power station base, underground city special map, achievements are as follows: After receiving the task, after entering the map, the upper right corner there is a countdown, before its zero to see the last green name - copy Furman, and kill it to complete the task of achievement. Power station base in a total of four green name, respectively, four power plant boss, the middle of the road there are mobs. But each green name will be refreshed when the players all the skills, so players can directly use all the high-level skills, as far as possible through the seconds to save time.
