Steel Structure Course Design The roof slope is 1 9 The decimal is calculated when calculating the h

The slope of the roof is 1:9, and the height of the span is calculated as a decimal, how to take the value", I can only use an example to talk about this problem.

1. If the project is a steel structure roof truss workshop, with a span of 18 meters and a slope of 1:9 on both sides of the roof, the distance from the ridge watershed line to the side column is 9 meters, and the height of the middle span is exactly 1 meter according to the roof slope of 1:9.

If the height of the roof truss at the steel roof truss bearing is meters, the height of the roof truss in the span is meters.

2. But the height of the span you said is a decimal, then the span of the roof truss is not exactly 18 meters as I gave this example, but such as 24 meters or 30 meters (the general steel structure is a relatively large span modulus of 6 meters), if it is considered according to 24 meters, the distance from the ridge watershed line to the side column is 12 meters, and the height of the span is 1 meter according to the roof slope of 1:9, and the size value accuracy is to millimeters in this case. If the height of the roof truss at the steel roof truss bearing is still considered in meters, the roof truss height in the span is meters.

The principle of taking the value of the height of the span when it meets a decimal place is: accurate to the millimeter.

i=1：12=1÷12≈。Slope is the degree of steepness of the surface unit, and the ratio of the vertical height h of the slope to the horizontal distance l is usually called the slope (or the slope beam ratio) and is represented by the letter i.

The slope of the slag spike is 1:12, i=1:12=1 12

30m slope 1:16 steel structure course design.

A workshop spans 30 meters, the length is 102 meters, and the column spacing is 6 meters. There are two 20 5t intermediate working stove cleaning cranes in the workshop. Before laughing, the temperature is calculated to be higher than -20, and the fortification intensity is 7 degrees.

The prestressed reinforced concrete large roof panel, 8cm thick foam concrete insulation layer, membrane roof, roof slope is i=1 10. The snow load is and the ash load is . The roof argument frame is simply supported on a reinforced concrete column, the upper column has a cross-section of 400 400, and the concrete number is C20.

It is required to design the roof truss and draw the roof truss diagram.

Summary. Hello dear, the questions you asked are as follows:1

The height of the sloping roof is determined according to the slope, and the slope should meet the specifications, and the relevant data should be consulted according to the latest version of the General Principles for the Design of Civil Buildings. 2.Now the slope of the commonly used slope roof generally adopts four points of water, and can also use five points of water or four and a half points of water, and the roof is as far as possible to adopt the practice of gable to the top.

For example, if it is a double-pitched roof, the depth of the front and rear is 12 meters. Sincerely hope to help you, I wish you a happy life! If you find it helpful to you, please give it a thumbs up, thank you!

Hello dear, I am helping you inquire about the relevant information and will reply to you immediately.

2.Now the slope of the commonly used slope roof generally adopts four points of water balance, and can also use five points of water or four and a half points of water, and the roof tries to adopt the practice of gable to the top. For example, if you want to bury hail, it is a double-slope roof, and the depth of the front and rear bend sails is 12 meters.

Sincerely hope to help you, I wish you a happy life! If you find it helpful to you, please give it a thumbs up, thank you!

How to calculate the slope of the house surface of the steel structure factory. It is known that the height difference of the steel column is 7 meters, and the height of the Jianding eaves is 3 meters.

Hello Kiss is happy to answer this question for you. How to calculate the slope of the house surface of the steel structure factory. It is known that the height difference of the steel column is 7 meters, and the height of the Jianding eaves is 3 meters.

Calculation of the slope ratio of the roof slope of the steel structure workshop and the roof of the industrial plant: If the angle between the roof and the horizontal plane is a, the height of the highest point is a, the height of the lowest point is b, and the distance between the highest point and the lowest point is c, then the calculation formula of the slope coefficient of the house is: tan a=(a-b) c.

The roof slope coefficient is the ratio of the height difference between the lowest and highest points of the roof (relative to the horizontal plane) and the horizontal distance between the lowest point and the highest point. The slope of the roof of the steel structure workshop should be 5% in accordance with the requirements of the steel structure design code, and the specific requirements should also depend on the technical requirements of the ground barrier and the roof panel.

If the roof is made of asbestos board, the slope is required and should be controlled at 33%.

36*15% slope height meters.

36 divided by 2 half of the span 18 meters.

Use the Pythagorean theorem, add the square of 18, and then the root number is right!
