How to calculate the floor area of the ramp, the construction area of the car ramp is calculated

If there is a roof on the ramp on the outside of the outer wall of the entrance, the area shall be calculated according to the horizontal area of the external wall structure of 1 2, and the horizontal area of the outer edge line of the outer wall of the basement and semi-basement shall be calculated, and the floor height and above shall be calculated according to the full area, and the area below shall be 1 2.

The maximum slope of the car ramp is 15% for straight ramps and 12% for curved ramps. When the longitudinal slope of the automobile ramp is greater than 10%, the upper and lower ends of the ramp should be provided with a gentle slope equivalent to the normal ramp 1 2. The horizontal length of the straight slope section of the gentle slope should not be less than, the horizontal length of the curved slope section should not be less than, and the radius of the curve should not be less than 20m.

Precautions for driving on ramps.

It should be noted that before going uphill, try to raise the speed as much as possible, and generally accelerate to more than 80 kilometers, so that it will be much easier to climb again, and it is more fuel-efficient. Acceleration begins at a distance of about 200 meters from the bottom of the slope.

Irrational overtaking on a ramp not only costs fuel, but also increases the danger, and the top of the slope is prone to collision and other dangers due to obstructed vision, or there are curves. Therefore, for the sake of safety and fuel economy, try not to overtake on ramps.

3 0 5 Basements and semi-basements should be calculated according to the horizontal area of the outer periphery of the structure. If the height of the structure is above and above, the full area should be calculated; If the height of the structure is below, the area of 1 2 should be calculated.

3 0 6 The part of the ramp on the outside of the entrance and exit with a roof shall be calculated according to 1 2 of the horizontal area of the outer wall structure.

Excerpted from the "Code for Calculation of Construction Area of Construction Projects" is a national standard, numbered GB T50353-2013, which has been implemented since July 1, 2014.

A simple calculation is not a 'formula'.

8400×2%＝168（mm）。It is long, and the height difference between the start and end points is 168mm.

Structural slope finding regardless of whether the concrete thickness is 8cm or 10cm.

The thinnest point of the building slope is 8cm, and the thickest point.

If the average thickness of the concrete is 8cm, it cannot be done. (Thinnest point, thickest point.)

1、a＝

a', and when S 0, it is an equal two-slope roof;

a a' s, for the same four-slope roof;

2. The area of the roof inclined paving roof horizontal projection area c;

3. The length of the inclined ridge of the equal four-slope roof: a d.

If the known slope angle is not in the gradient coefficient table of the fixed roof, the C=1 COS formula is used to calculate the extension coefficient C directly.

Or use the formula c=[(a2+b2)1 2] a to directly calculate the drag coefficient c.

For example: slope height b=, horizontal length a=, then b a=, not in the fixed roof slope coefficient table, calculate c=[(1 2].

The extension coefficient d is calculated as follows: d=(1+c2) The extension coefficient d can be used to calculate the length of the slope ridge of the four-slope roof.

Slope length = slope horizontal length provided by d.

Roof slope = b a=, check the roof slope coefficient table to get c =, roof slope area = (50 + 18 +

Check the roof slope coefficient table to get d =, single-sided inclined ridge length = a d =, total length of inclined ridge: 4

Ridge length = (50 + 2).

The most commonly used method of expressing the slope, i.e., the percentage of the difference in elevation between two points and their horizontal distance, is calculated as follows: slope = (elevation difference horizontal distance) x 100%.

Example: The slope of the slope is i=1:2, if a person travels 100 meters up the slope, how many meters will his height rise.

Solution: Because of the slope - the ratio of the straight height h to the horizontal width l of the slope is usually called the slope (or slope ratio), which is represented by the letter i. It is usually expressed as a percentage.

Then, there is: the height rise is: x + (2x) = 100 5x = 100

x√5=100

x=100 5 because 5= 5 5* 5x=20 5

Simplified to: 100 * 5 5 = 20 5 meters.

The norm is to ascend 8 meters for every 100 meters (you draw one.)

For example, if the straight-line distance from the highest point of your slope to the lowest point is 1 meter, you draw a line of one meter in the triangle, like this;

and then connect them again;

Then, the bottom of the triangle is the length you need to do, I don't need to calculate this method, generally only used to draw construction drawings, of course, you can use it to understand, if you want to calculate math problems, mathematics is better and directly set of formulas.

1. The calculation of slope is the tangent value of a triangle, that is, the vertical side of the right angle is higher than the horizontal side. For example, if a road with a horizontal distance of 100 meters rises by 5 meters, it will have a slope of 5%.

2. Slope, usually the ratio of the straight height h and the horizontal width l of the slope surface is called the slope (or slope ratio) and is represented by the letter I. It is usually expressed as a percentage.

i.e.: i=h l 100

In fact, the slope is simply the tan (tangent) value.

Use the percentage method.

The most commonly used method for expressing slope, i.e., the percentage of the difference in elevation between two points and their horizontal distance, is calculated as follows: Slope = (Elevation Difference Horizontal Distance) x 100% When expressed as a percentage, i.e., i.e. i=h l 100%.

For example, a slope of 3% refers to a horizontal distance of 3 meters per 100 meters and a vertical rise (descent); 1% refers to the horizontal distance of every 100 meters, vertical rise (fall) 1 meter. And so on.

Degree method: The slope is expressed in degrees, calculated by inverse trigonometric functions, and its formula is as follows: tan (slope) = elevation difference horizontal distance.

So (slope) = arc tan (elevation difference horizontal distance).

Slope = elevation difference Horizontal distance, for example, the horizontal distance between two points of a slope is 100 meters, and the vertical distance is 2 meters, and the slope is 2%. Understand this formula、You draw a right triangle, hypotenuse, and then (triangle height width = 2%) set the height to h, the width is 50h, what do you need to calculate, it should be relatively simple, junior high school geometry problems.

The amount of ramp engineering is calculated according to the "horizontal projection area". You can use the Step component instead of drawing to calculate the quantities of the ramp. If you want a spiral ramp, you can use the "Spiral Slab" component instead of drawing the calculation, and calculate the engineering quantity of the ramp according to the "Slab Area".

When it is not possible to build a step due to use or other reasons, a ramp can be used to cope with the change in height. Public green spaces and public buildings often require barrier-free access, and ramps are an essential factor. Ramps are an important way to make pedestrians highly transformed on the ground.

Related information. As a general rule, the ramp should be placed on the main activity route as much as possible, so that pedestrians do not have to leave the ramp to reach their destination. Finally, it should be mentioned that the location and layout of the ramp should be decided as early as possible in the design, because we need to match it with other elements in the design, otherwise the ramp will look out of place.

In conclusion, the ramp should be a very coordinated element in the overall layout. Combining ramps with steps is an innovative design approach.

According to the size shown in the design drawing, the area is calculated by area, and the area occupied by the hole within square meters is not deducted.

According to the projection area, for the set of quotas, you have to look at the detailed atlas and practice details to get the quota.

According to the relevant provisions of the national "Code for the Calculation of Construction Area of Construction Projects", the ramp is in the main body of the building, and the area of the natural layer of the underground part is calculated. The ramp is outside the main building, and is provided with a roof, and the area is calculated according to 1 2 of the peripheral horizontal area of the structure, and the area is not calculated for others. I think it's useful to like it, car ramps are generally divided into straight ramps, curve ramps, straight curve hybrid ramps and spiral ramps, the slope of the straight line is 15%, and the slope of the curve is 12%.

At the entrance and exit of the car ramp, the one-way lane is 6m, the two-way lane is 6m, and the turning radius of the curved ramp shall not be less than the same. The calculation requirements of the ramp construction area, the outer position of the entrance and exit exterior wall bend shed ramp with a covered part, according to the horizontal area of the exterior wall structure 1 2 to calculate the area, basement, semi-basement according to the outer edge of the outer wall of the outer edge of the horizontal area to calculate, the floor height and above according to the full area, below the 1 2 area. If you think it's useful, bury it, and give it a thumbs up.

Summary. The area is generally calculated by multiplying the horizontal projection area of the roof by a (slope roof coefficient). The a-value is calculated from the slope coefficient.

For example, the slope factor is 1:4, i.e. 4 meters horizontally and 1 meter high. a*a=(1+1*1 4*4)=If you know the horizontal size and height of a single slope, the calculation is the same.

Hope mine can help you.

The area is generally calculated by multiplying the horizontal projection area of the roof by the calendar a (slope roof coefficient). The a-value is a group of clusters obtained from the slope coefficient. For example, the slope factor is 1:

4, i.e. 4 meters horizontally and 1 meter in height. a*a=(1+1*1 4*4)=If you know the horizontal size and height of a single slope, the collapse calculation is the same. Hope mine can help you.

I hope mine can help you.

If you know the length of the slope, multiply it by the width to get the area.

If you only know the horizontal length of the slope, assume that the slope you know is the slope (elevation difference horizontal length) expressed as 100%.

Then the area of the slope width * root number (square of horizontal length + square of elevation difference).
