A special anti-seismic escape staircase for hospital wards

Abstract

The invention discloses an anti-seismic escape stairway special for a hospital ward. The escape stairway comprises multiple stairway platforms, wherein adjacent stairway platforms are connected through stairs, a step is arranged in the middle of the top surface of each stair, ramps are arranged on the two sides of the steps respectively, central supporting pillars perpendicular to the horizontal plane are arranged between every two adjacent lines of stairs, the middle of the bottom surface of each stair is provided with a boss protruding out of the bottom surface of the stair, a supporting arm is arranged on the bottom of each boss, the supporting arms are connected with the central supporting pillars, buffer rubber mats are arranged between the supporting arms and the bosses, a preformed hole is formed in the middle of each stair, an embedded pillar is installed in each preformed hole, the lower end of each embedded pillar is connected with the corresponding supporting arm, and each preformed hole is filled with concrete. The anti-seismic escape stairway special for the hospital ward has the advantages that the anti-seismic strength of the stairway of the hospital ward can be effectively improved, a precious escape and rescue channel is reserved for people in and after an earthquake, casualties in a seismic disaster are reduced, and rescue staff can transfer critical patients in the hospital ward conveniently due to the fact that the ramps special for sickbeds are arranged on the stairs.

Description

technical field [0001] The invention relates to a building staircase, in particular to a special anti-seismic escape staircase for a hospital ward. Background technique [0002] In recent years, with the continuous increase of urban population density, more and more hospitals have adopted multi-storey and high-rise wards. In multi-storey or high-rise wards, medical staff and patients mostly use elevators to go up and down. However, once an earthquake occurs, the stairs It has become the only escape channel for medical staff and patients on floors 2 and above, but the applicant has analyzed the damage of buildings that have not completely collapsed in several destructive earthquake-stricken areas that have occurred in my country in recent years. It was found that although the main part of the building has not yet collapsed, most of the stairs in these buildings have collapsed in the earthquake, and even some buildings far from the epicenter have broken in the middle of the stai...

[0002] In recent years, with the continuous increase of urban population density, more and more hospitals have adopted multi-storey and high-rise wards. In multi-storey or high-rise wards, medical staff and patients mostly use elevators to go up and down. However, once an earthquake occurs, the stairs It has become the only escape channel for medical staff and patients on floors 2 and above, but the applicant has analyzed the damage of buildings that have not completely collapsed in several destructive earthquake-stricken areas that have occurred in my country in recent years. It was found that although the main part of the building has not yet collapsed, most of the stairs in these buildings have collapsed in the earthquake, and even some buildings far from the epicenter have broken in the middle of the stairs when the main part of the building is basically intact. deformation

The applicant, after analyzing the stairs of many buildings with different degrees of damage, found that the stairs will first produce cracks in the middle during the earthquake, and the concrete structure of the stairs will be broken at the cracks. At this time, the upper and lower parts of the stairs are only It is connected by the steel bars at the cracks, and the steel bars are difficult to maintain the original shape of the stair boards, so the stair boards will be sunken downwards at the cracks in the middle. Cracks are produced at the joint between the top of the slab and the floor slab, causing the concrete here to break. At this time, the weight of the entire stair slab is applied to the steel bars at the joint between the top of the stair slab and the floor slab. Bending occurs, its own strength has been greatly reduced, and it is very easy to be completely broken when the escapees pass by or in the aftershocks, causing the whole stair board to fall, and as long as one stair board falls in the building, all the stairs below it will be damaged. The slabs will collapse accordingly, causing people to lose the only escape and rescue channel, and the collapse of the stair slabs will also cause fatal injuries to the people who are escaping on the stairs.

In addition, because some patients with serious conditions in the ward cannot escape by themselves, they need to be transferred out of the ward together with the hospital bed during or after the earthquake. If the elevator cannot be used, they can only go downstairs by stairs. The weight of the hospital bed, the patient and the rescuers are all applied on the stair slab, which can easily cause the middle part of the stair slab damaged in the earthquake to break, causing the stair slab to sag downward, thus causing the collapse of the staircase
