Problems solved by technology
[0004] There is only one ramp in the spiral ramp, but the architectural design is limited by daily use and fire evacuation requirements, it is necessary to set up 2 or more spiral ramps, resulting in a large number of ramps and occupying a large building area
[0005] The increase in the number of ramps leads to the need for more space on the first floor to arrange ramps and organize the flow of people, which further limits the land utilization rate of the first floor and the flexibility of architectural design

The invention discloses double helix scissor car ramps. The double helix scissor car ramp is characterized in that a helical ramp projection line is internally provided with two spiral ramps, the twospiral ramps are axisymmetric at 180 degrees and slope surfaces are parallel to each other. According to the double helix scissor car ramps, the two parallel scissor car ramps are arranged in each spiral ramp on the premise of the same number of parking and the same level of floor height, thus the requirements of daily traffic are met, and the requirements of fire-fighting evacuation for the number of car evacuation ramps are solved. In addition, compared with traditional spiral ramps, a ground floor can reduce at least one spiral ramp, traffic stream lines in a general drawing are easier to organize, and the architectural layout is more flexible, and therefore, the double helix scissor car ramps can produce significant economic value.
Description
technical field [0001] The invention relates to construction and municipal engineering technology, in particular to a double-helix scissors car ramp. Background technique [0002] With the continuous expansion of the building scale and the increasing shortage of land use, improving the land utilization rate has become one of the key issues in design; at present, the basement of the building is mainly used as a car parking garage, and the car ramp is an important part of the car garage, which undertakes daily use. and the role of car evacuation, the spiral ramp is widely used due to its compact plane; however, the spiral car ramps commonly used at present lack innovation and technical research. Evacuation requirements often require setting up two or more car ramps, which occupy a large building area and are not efficient. [0003] That is, the traditional spiral car ramp that is often used at present mainly has the following problems: [0004] There is only one ramp in the ...
