Abstract

The utility model relates to a novel high -rise building stair, these stair include at least a set of stair unit, and wherein every group stair unit includes two upper and lower stair, its characterized in that: the middle part of two upper and lower stair, set up the platform to the department sets up the entrance to a cave at the platform, the entrance to a cave can communicate two stair, two such stair just can communicate in the middle part. The utility model discloses an advantage and effect be: because walk up and down stairs's middle part has set up interconverting's passageway, has just so made things convenient for people's walking. Because the middle part at walk up and down stairs has set up the half space, also being convenient for go up downstairs, personnel have a rest.

Description

A kind of Novel high-rise architectural stair

Technical field

The utility model patent relate to the concrete component in a kind of highrise building, particularly relates to a kind of for the stair in highrise building, is a kind of novel stair.

Background technology

The same with the every other industry in national economy field, since reform and opening-up, China's building trade experienced by the process of a high speed development.Along with the development of China's urbanization, capital investment is in the large-scaled construction period, makes civil engineering industry be in the state continuing expansion all the time.Approximately from eighties of last century eighties, highrise building just starts a large amount of construction in China, nearly more than 10 years, and high residential building building project has also occurred in a large number.In high residential building is built, often can design two scissor stair, its stair can be connected by corridor at floor place, but can not intercommunication in the centre of stair.See Fig. 1.

Scissor stairs is also known as intersection stair, superimposed stair, cover ladder.As Fig. 2 has two kinds of forms, be the two race formula of a single flight formula and b respectively.Single flight scissor stairs is formed by two single flight bench intersections.Two race scissor stairs adds shared halfpace by two single flight bench and combines.As shown in Figure 2, dog leg staircase is exactly arrange two stair in a staircase, and two stair accesss are respectively on different positions.Utilize the area shared by a staircase, lay out two stair, this is one of feature of dog leg staircase, and in addition, in planar design, it can also make Ministry of Communications divide concentrated and be conducive to layout.Due to two stair that its picture merges, so, not only have than the twice traffic of general stair, evacuation capacity, and staircase two ends all can be upper and lower, also constitutes two-way evacuation.This is also not available between independent stairs.In tower building, adopt the dog leg staircase of concentrated and compact " uniting two into one ", " high-rise civil building fire code " (GB50045-95) can be met to the requirement of tower building two emergency exits, satisfied usable floor area coefficient can be obtained again.

But as can be seen from Figure 2, such stair have a shortcoming, be exactly can only change at floor place between two stair.

Summary of the invention

The object of the utility model patent is to provide a kind of Novel high-rise architectural stair, makes by channel connection between two step stair, thus is convenient to people's walking.

The utility model patent is achieved through the following technical solutions: these stair comprise at least one group of stairway unit, wherein often organize stairway unit and comprise upper and lower two stair, it is characterized in that: in the middle part of described two stair up and down, platform is set, and hole is set at platform place, described hole can be communicated with two stair, and such two stair just can be communicated with in middle part.

Described stair are scissor stairs.

Described hole connects two stair.

Described hole place arranges labeled door.

Described platform is half space.

Advantage and the effect of the utility model patent are:

1., because the middle part of stair activity is provided with the passage changed mutually, so just facilitate the walking of people.

2., because the middle part at stair activity is provided with half space, be also convenient to personnel downstairs and have a rest.

Detailed description of the invention

As shown in Figures 3 and 4, the utility model patent is achieved through the following technical solutions: these stair comprise at least one group of stairway unit, wherein often organize stairway unit and comprise upper and lower two stair, be respectively the distant stair of range gate M2 2 and the closer stair 3 of range gate M2, M2 door is the door that highrise building corridor is connected with stair, in the middle part of described two stair up and down, platform is set, and hole is set at platform place, described hole can be communicated with two stair, and such two stair just can be communicated with in middle part.

Described stair are scissor stairs.

Described hole connects two stair.

Described hole place arranges labeled door 1.

Described platform is half space.

Claims

1. a Novel high-rise architectural stair, these stair comprise at least one group of stairway unit, wherein often organize stairway unit and comprise upper and lower two stair, it is characterized in that: in the middle part of described two stair up and down, platform is set, and hole is set at platform place, described hole can be communicated with two stair, and such two stair just can be communicated with in middle part.
