Anonymous users2024-02-07a.Approximate calculation of the load P borne by the foundation: p = (cage weight + outer cage weight + counterweight + total weight of guide rail + load) For example, the erection height of SCD200 200 is 150 meters, and the maximum pressure is pmax = 710kn);
b.The ground bearing pressure under the concrete foundation slab shall not be less than, the foundation is poured C30 concrete, and the thickness of the foundation concrete is not less than 330mm;
c.Reinforcement grid: diameter of 8mm steel bar, square interval of 250 250 250mm;
d.The concrete foundation plane should be smooth and clean, and the levelness error of the foundation plane should not be greater than 5mm;
e.The anchor bolt hook must hook the rebar of the rebar grid and weld it firmly;
f.The strength of the foundation concrete must reach more than 70% of the design strength before the machine can be erected.
Approximate calculation of the base bearing p.
p = (cage weight + outer cage weight + total weight of guide rail frame + counterweight + load weight).
For example, SCD200 200 elevator has an erection height of 150m (see "Lift Performance Parameter Table" for weight).
Cage weight (double cage): 1600 2kg
Outer cage weight (fence): 820kg The total weight of the rail frame (a total of 100 standard sections is required, each section weighs 184kg), 184 kg 100
Counterweight (double weight) 1100 kg 2
Each car has a load capacity of 2000kg 2000 kg 2
The base bearing is approximately equal to:
p = [(1600×2)+820+(184×100)+(1100×2)+(2000×2)]×
60102 kg
60102 kg × n/kg = 589000 n = 589 kn
If the foundation is made according to the maximum pressure pmax = 710 kN, it meets the requirements for the use of the lift. The pressure on the ground shall not be less than.

Anonymous users2024-02-05Summary. The high point of local concrete pouring on the roof of the basement will be added, and the roof will be reinforced and supported by steel pipes or temporary structural columns;
Is elevator foundation concrete calculated according to drawings? Generally, the engineering quantity is calculated according to the drawings.
Is it a permanent elevator or a temporary elevator for construction?
The contract generally stipulates that the main structure is calculated according to the drawings.
Yes, the concrete and steel bars of the main structure are calculated according to the drawings.
What if it's a temporary elevator for construction?
The permanent elevator foundation and design drawings will have side walls and bottom plates in the basement drawings.
Construction elevators, there are.
There is an invoice, ** part of the elevator foundation, I think it should be a temporary elevator construction, should be calculated according to the facts, right?
The high point of local concrete pouring on the roof of the basement will be added, and the roof will be reinforced and supported by steel pipes or temporary structural columns;
Some don't have a basement, so they pour a similar independent foundation, and put steel bars inside.
In the case of an independent foundation, the basic part is calculated based on facts?
It is estimated that it is a construction elevator. Permanent elevator foundations are generally contained in the basement.
There are also drawings for the independent foundation, and the supporting drawings given by the construction elevator manufacturer, how long and wide and how thick the site can be done according to this.
Oh, that is, whether it is a construction elevator or a permanent elevator, it should be calculated according to the drawings?
Yes, it is calculated according to the drawing. Regardless of whether it is permanent or temporary.

1. The nature is different.
On-site visa, when there is a problem during the construction process, because it takes time to submit for approval, it is a process of approval by the person in charge of the site on the spot at the construction site. The on-site representative of the employer (or its authorized supervisor or project cost consultant) and the on-site representative of the contractor shall sign and certify the liability events involved in the construction process. >>>More

I once knew a girl who came from a scholarly family, her parents were both university professors, and she started reading from a few years old until she was in her twenties, and every night when she went home and washed up, she had to read for two hours, and she took out a book from her bag to read in her free time. >>>More
