In recent years, the development of China has been affirmed all over the world, at the same time, China's urban construction is also advancing by leaps and bounds, the rapid development of residential construction, but due to the proportion of elderly people in society has increased year by year, high-rise residential medical emergency More emphasis on the current residential construction has put forward higher requirements, in addition to barrier-free design of the gradual improvement of the residential elevator needs to be designed to accommodate the stretcher and to meet the requirements of the patient stretcher ambulance transport. This paper presents two options for the placement of stretchers in a residential design, as well as the rational size of the car that can accommodate the stretcher.

"Residential Design Code" (GB50096-2011), for twelve and more than twelve-story residential buildings should be set up for each one can accommodate a stretcher of the elevator, the provisions will be implemented in August 1, 2012, which Requirements, residential design in the program phase will be a reasonable design and layout.

For the 12-storey and 12-storey residential, each unit will be equipped with two elevators, the current medical elevator of the smaller car size, length 2400, width 1400, the corresponding shaft length 3000, width 2400, and conventional Residential elevator shaft size of 2000 × 2000 or so, the difference between the size of the shaft is relatively poor, for the public part of the public elevator, staircase, elevator hall layout will be difficult to combine. If the direction of the car is perpendicular to the hall, the depth of the hall is greater than the depth of the car. Resulting in an increase in the pool area of the residence.

Is it possible to compress the car size, but at the same time to meet the transport requirements of the stretcher, or trolley cab arrangement?

We now need to analyze the minimum space needed to move the stretcher smoothly into the elevator car.

The size of the stretcher we take: long 1980, wide 530. Can include the ambulance stretcher maximum outsourcing size.

Let us draw the trajectory path of the stretcher in the car at a 90 degree angle. The stretcher moves at a right angle of 90 degrees. We take the step length of 50mm, that is, the stretcher enters the car to draw a stretcher outline every 50mm.

From the trajectory of the stretcher, we can find that the inner surface of the elevator car can meet the requirements of the elevator to accommodate the stretcher as long as it does not cross the trajectory of the stretcher. We control the stretcher before and after the stay of 25 mm of the safety distance can be calculated, the direction of the long side of the car needs to have 2100mm of net space.

The doorway of the car is l150 net width, the short side of the car can be done l100, this time stretcher from the car there are 70 mm distance. From the above analysis can be drawn, if the elevator made the direction of the depth of 1100, the width of 2100, the elevator door close to the side of the car open, the width of 1200, can be stretchered in the elevator within the rotation to meet the needs of daily medical assistance. Read the elevator manufacturers of information and found that Mitsubishi Elevator has a sample of the elevator used in foreign countries, his car size just to meet our projected requirements (2100 × 1100). Corresponding hoistway size is within the net 2550 × 1750.

The conclusion is that residential stretchers are arranged not only in the vertical direction (the car door is in the narrow side direction) but also in the lateral direction (the car door is in the long side direction), so that the house is provided with a stretcher ladder, In the layout of the layout of a more than a choice of the car.

According to conventional design, twelve and more than twelve-story residential buildings should be equipped with two elevators, one for the stretcher elevator. Ordinary elevator hoistway size is usually 2000 × 2000, combined with the actual project, try to increase in the original architectural plane stretcher ladder program design, floor elevator layout for the combination of the former room mode, two non-stretcher side by side side of residential ladder layout, Side of the equipment arranged pipe wells, waiting hall to lift the staircase and separated from the waiting hall ladder width 1800.

Stretcher elevator program: the original design of residential ladder hoist depth of 2200, stretcher elevator shaft depth direction of 1750, less than 2200, depth direction to meet the minimum depth requirements of the elevator shaft stretcher, the direction of the width of the extension to the equipment pipe wells to ensure the well The long side direction dimension is 2550. In order to ensure the opening of the elevator doors to ensure the net width of 1,200, civil construction of the elevator door width control in the 1400 size. Close to the car side open. The space of the pipeline well is squeezed. In order to compensate for the reduced area of the pipe well, it is considered to increase the water well elsewhere. After the water well is separated, the area of the electric well can be improved; the elevator tube well can be moved up Equipment, tubing area requirements. This program can maximize the reduction of pool area, improve residential housing rate. So that after the increase of stretcher ladder, the construction of the increase in control of the pool in the smallest range. To reduce the floor elevator protruding contours of the width of the house, to reduce the impact of the rear building sunshine is a great help.

To explore another floor layout of the layout of the elevator, for two non-stretcher residential door to the door, on both sides of the layout, waiting hall depth of 2500, the elevator shaft width 2200, 1900 deep. The elevator shaft is adjacent to the kitchen and dining room.

Increase the stretcher ladder, if you consider the direction of deep 2550, 1750 width of the layout of the way, then the restaurant will cause greater impact, the restaurant will become irregular, the width direction of the reduction of 650, the impact is still relatively large. It is considered that the size of the hoistway in the depth direction of the stretcher ladder is designed to be 1900, the minimum size of 1750 is satisfied, and the widthwise direction is extended to 350 in the kitchen direction, and the area of the kitchen is less affected. The horizontal arrangement of the stretchers (shallow car arrangement) adds diversity to the design of the common parts of the dwelling and avoids the arrangement of the deep-car only in the litter elevators. Whether from the facade design or the functional layout of the public areas, The layout of the car, certainly brings greater flexibility and feasibility.

In conclusion

The minimum dimension of the car is 1100 in the depth direction, 2100 in the width direction, and 1200 in the width direction, and is opened in the side close to the car. Such a car arrangement can accommodate a length of 1980, a wide 530 stretcher smoothly into the car. Which provides the design basis for the horizontal layout of the stretcher elevator. It can reduce the whole building surface width of the elevator and reduce the sunshine effect to the rear building. It can also reduce the residential pool area , To improve the unit was room rate; at the same time to save the lives of patients to solve the vertical traffic.
