Description
Technical field
The utility model relates to building safety and evacuates technical field, specifically a kind of business buildings being provided with escape stair.
Background technology
In business buildings, personnel's flow is usually larger.Therefore, in order to tackle the accidents such as fire, business buildings needs to provide good evacuation capacity, and personnel can be escaped from smoothly at clutch from business buildings.In the business buildings being provided with underground parking, in order to meet the regulation of " Code for fire protection design of buildings ", ensure the evacuation capacity of business buildings, usual need arrange the larger escape stair of width, and, as depicted in figs. 1 and 2, no matter be for purchase and consumption or the ground floor of service transacting or the underground floor as parking lot, the escape stair of same widths is all set.But, owing to resting on visitors flowrate in the parking lot visitors flowrate far away from purchase and consumption in floor on the ground within the same period, therefore, wide escape stair is set in underground parking and is actually waste to space.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of business buildings being provided with escape stair, makes full use of the space of business buildings while can meeting evacuating personnel.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of business buildings being provided with escape stair is provided, described business buildings comprises: the first floor, be positioned at the underground floor being used as underground parking below described first floor, and the ground floor be positioned at above described first floor, be provided with the first emergency staircase in described first floor, in the floor of described underground, be provided with the second emergency staircase;
Be provided with in described first emergency staircase of described first floor: common platform, the first escape stair section and the second escape stair section, described first escape stair section is for connecting described common platform and described ground floor, and described second escape stair section is for connecting described common platform and described underground floor;
Described common platform place is provided with partition, the space at described common platform place is divided into the second evacuation compartment being communicated in first of described first escape stair section and evacuating compartment and be communicated in the second escape stair section by described partition, described first evacuates compartment is provided with the first egress door, the outside and described first escape stair section for business buildings described in traffic connection; Described second evacuates compartment is provided with the second egress door, the outside and described second escape stair section for business buildings described in traffic connection;
Be provided with in described second emergency staircase of described underground floor: the 3rd escape stair section, the first conversion platform and the 3rd egress door, described 3rd escape stair section is connected to described underground floor and described first conversion platform, described second escape stair section is connected to described first conversion platform and described first common platform, and described 3rd egress door is used for underground floor and described 3rd escape stair section described in traffic connection; The width of described first escape stair section is H, and the width of described second escape stair section and the 3rd escape stair section is h, 0.5H < h < H.
Further, the 3rd emergency staircase is provided with in the floor of described ground, be provided with in described 3rd emergency staircase: the 4th escape stair section, the 5th escape stair section, the second conversion platform and the 4th egress door, described 4th escape stair section is connected to described ground floor, described 5th escape stair section is connected to described ground floor and described second conversion platform, and described first escape stair section is connected to described second conversion platform and described first common platform; Described 4th egress door is used for ground floor, described 4th escape stair section and described 5th escape stair section described in traffic connection; The width of described 4th escape stair section and described 5th escape stair section is H, identical with the width of described first escape stair section.
Preferably, the width H of described first escape stair section is 2025mm, and the width h of described second escape stair section and described 3rd escape stair section is 1250mm.
Further, described escape stair is two race stair.
Compared with prior art, beneficial effect is as follows:
1, the evacuation capacity of escape stair is ensured.In the utility model, the width of each floor escape stair is under the prerequisite considering each factor such as floor building area, personnel's flow, by calculating and meeting the width that " Code for fire protection design of buildings " require.In the floor of, number comparatively dense more at visitors flowrate, escape stair width arranges wider, and for ensureing when running into the accidents such as fire, these floors have good evacuation capacity, and crowd is withdrawn in time.In the underground parking that visitors flowrate is less, escape stair width arranges relative narrower, but the stream of people that can meet underground parking equally evacuates in time.Therefore, when running into accident, even if the width of each floor escape stair of business buildings is different, but still good evacuation capacity can be ensured.
2, make full use of floor space, reduce construction cost.When the utility model is identical with the floor space of underground of the prior art floor, because the width of the escape stair of underground floor in the utility model arranges narrower, accordingly for underground floor reserves the space being more used for parking cars, be fully used in the space of underground floor.In addition, because the escape stair of underground floor reduces to some extent relative to the escape stair width of ground floor, therefore, related personnel is when constructing, and required construction material and engineering time be all relative to be reduced, and saves construction cost.
