How to choose the size of the stretcher elevator mentioned in the new specification

The Residential Design Code does not explicitly state this. This is the difference between engineering and technical standards and product standards.

At present, there is no product and corresponding product standard for "accommodating stretcher elevators" in China.

However, what is clear is that the "medical elevator" cannot be used blindly. The design of the medical elevator is often that the stretcher can enter the elevator but cannot enter the house.

The correct response to similar national engineering and technical standards is to form implementation rules at the local level. At present, the relatively centralized measures in various places are: the selection of 1500x1600 car, the current is 1000kg, and the future 800kg can meet the requirements.

Referring to Article 1 of the "Shanghai Residential Design Standards", the stretcher elevator should be not less than one meter on the long side.

However, the size of the hoistway of the medical elevator is mostly 2500mmx2900mm. Regarding the design of the hoistway, you had better go to the design institute to report and let the design institute design it for you. The Residential Design Code does not explicitly state this. This is the engineering specification.

There are many manufacturers who make the elevator narrow and long, but they don't know how harmful it is. As soon as the new version of the "Residential Design Code" came out, many elevator manufacturers were left alone. Although the 630kg load can also be loaded with a stretcher, it cannot ensure that the first aid personnel and the patient's family can get on and off the elevator together.

Please refer to the description of the provisions of the Code for Urban Roads and Barrier-free Design, and you may understand

Basic specifications of stretcher elevator: elevator load capacity: 1000kg, car internal dimensions: m width x m, deep bureau shaft plane size: m width x m, deep net door size: m width x m height.

Residential use is mostly the elevator of car size meters (width and depth) fixed load ton, and it is more difficult to put the car into the stretcher. The size adjustment of the product becomes inevitable.

Elevator manufacturers should combine the reality of Chinese multi-height buildings to produce suitable Chinese residences.

Featured products. Usually, the length of the general small high-rise staircase is one and a half meters, and the width is in meters, which is completely impossible to put down the stretcher, even if it is an ordinary stretcher, the length and width of the stretcher are two meters long.

Legal Analysis: 1. There is currently no clear size regulation.

2. Proposed through the "Guidelines for the Implementation of Residential Design Codes":

1. You can't blindly choose a medical elevator;

2. The contradiction between engineering construction standards and product standards is being coordinated;

3. Starting from the transformation of the stretcher and the use of the diagonal of the residential elevator car, the design parameters of "accommodating the stretcher elevator" are proposed;

4. Support the use of demonstration meetings in various places to form minutes, and it is basically feasible to choose 1000kg and 1500x1600 cars.

Legal basis: Residential Design Code

6 4 1 An elevator must be installed in one of the following cases:

1. When the height of the entrance floor of a residential or residential building with seven or more floors exceeds 16 m from the outdoor design floor;

2. When the floor of a residential building with six floors or less on the ground floor is used as a shop or other building, and the entrance floor of the occupant is more than 16 m above the designed outdoor ground level of the building;

3. For a residential building with six floors or less on the ground floor as an overhead floor or storage space, the entrance floor of the residential building is more than 16 m above the outdoor design ground height of the building;

4 When the top floor is a two-storey duplex dwelling, the height of the entrance floor of the top floor of the building exceeds 16 m from the outdoor design ground of the building, regardless of the number of floors.

6 4 2 For residential buildings with 12 floors or more, there should be no less than two elevators in each building, of which one elevator should be provided that can accommodate stretchers.

6 4 3 Where there is only one elevator per unit of a dwelling with 12 floors or more, a connecting corridor should be installed from the 12th floor onwards to connect with the adjacent residential units. The contact corridor can be set up with smiling pants on the next floor, and the interval between the upper and lower contact corridors should not exceed five layers. The clear width of the corridor should not be less than 1 10 m, and the local clear height should not be less than 2 00 m.

6 4 4 12-storey and above dwellings consist of two or more dwelling units. If one or more residential units are not equipped with an elevator that can accommodate a stretcher, a connecting corridor shall be set up from the twelfth floor onwards to connect with the elevator that can accommodate a stretcher. The corridor can be set up in compartments, and the interval between the upper and lower corridors should not exceed five floors.

The clear width of the corridor should not be less than 1 10 m, and the local clear height should not be less than 2 00 m.

6 4 5 Residential elevators on seven floors or more shall have stations on each floor with doors and common corridors. Residential elevators should be arranged in groups.

6 4 6 The depth of the waiting hall should not be less than the depth of the largest car in multiple elevators, and should not be less than 1 50m.

6 4 7 The elevator should not be arranged immediately adjacent to the bedroom. When the elevator has to be arranged next to the bedroom that is also living and living due to the constraints, the structural measures of sound insulation and vibration reduction should be taken.

Now the floors of the house are getting higher and higher, people will be very troublesome when they go up and down the stairs, the emergence of the stretcher elevator can make people quickly and easily up and down the floor, but how to design the size of the stretcher elevator is more reasonable? What is the difference between it and an ordinary elevator? I believe that many owners want to understand these problems, so if you want to know this knowledge, then hurry up and take a look.

1. What is a stretcher elevator?

Stretcher elevator is not a type of elevator but a name, it is an ordinary elevator, and the purpose is exactly the same as the elevator, but its size requires that it can put down a stretcher, which is convenient for the stretcher to pick up and drop off patients into the elevator, so it is called a stretcher elevator.

Second, how to design the size of the stretcher elevator.

Taking the ordinary stretcher on the market as an example, its length is about two meters, so the length of the stretcher elevator must be greater than two meters, and the width is recommended to be more than one meter. At present, the elevator size of many residences is one and a half meters in length and one meter in width, which is far less than the size of the stretcher, resulting in the stretcher being unable to enter and exit the elevator.

The small net size of the stretcher elevator shaft given by the regular elevator company is: 2200 x 2850 depth. What is the specific value, but also need to be combined with the area of the house.

Due to the need to waste a relatively large shared area of stretcher elevators, many developers are now reluctant to do stretcher elevators, and owners will not take the initiative to require the development of stretcher elevators, resulting in fewer and fewer stretcher elevators.

3. The difference between a stretcher elevator and an ordinary passenger elevator.

The counterweight of the ordinary passenger elevator is arranged behind the elevator car, and the internal space of the car belongs to the square, which is more convenient for passengers to enter and exit, because the internal swing area is larger; In order to allow the stretcher to enter, the internal space of the stretcher elevator will be rectangular, because the stretcher is rectangular, and the counterweight arrangement has also been changed from the original back to the side.

The specification group did not specify the size of the limb rot, but through the "Residential Design Code Implementation Guide", it was proposed: 1. Medical elevators cannot be blindly selected; 2. The contradiction between engineering construction standards and product standards is being coordinated; 3. Starting from the transformation of the stretcher and the use of the diagonal of the residential elevator car, the design parameters of the "accommodating stretcher elevator" grip leakage are proposed; 4. Support the use of demonstration meetings in various places to form minutes, and it is basically feasible to choose 1000kg and 1500x1600 cars.
