Description
Technical field
The present invention relates to building construction technology fields, and in particular to a kind of building are fast and safely escaped spiral slide.
Background technology
When earthquake, fire, tsunami come interim, the escape mode of domestic building inhabitation personnel selection is most people from stair
Mouth is toward undershoot, this is because elevator open circuit at this time or deformation can not be taken, it is clear that this escape mode is for high level inhabitation
Have little time for personnel.Also have using escaping rope fast-escape in the prior art, but there are many its disadvantage, when earthquake, fire,
Tsunami carrys out interim, the life of one minute and one second all deciders, and fastens escaping rope and need to spend the regular hour, and time is too long,
Safety is only suitable for the young man of figure agility almost without guarantee, is not suitable for elderly and infirm, makes a general survey of over several years with escape
It is seldom that rope escapes from the people come.Chinese patent CN2322348Y discloses a kind of spiral slide for rescuing, by top plate, spiral slide, master
Bar, support plate, inside and outside guardrail, water jet and escape and rescue trunk composition, when fire alarm or other accidents occur, escape personnel is from lifesaving
Channel step on be seated at spiral slide take advantage of a situation downslide escape.Although fast-escape can be solved the problems, such as by changing patented technology, its facility mistake
In complexity, water jet without using blocking is be easy to cause, can not play the effect of wet and slippery escape, inside and outside shield at all when in use for a long time
For a long time without using corrosion is be easy to cause, being likely to occur stuck can not rotate in escape is easy to cause accidental wound to escape personnel on column
Evil.
Invention content
The spiral slide in order to solve the above technical problems, a kind of building of present invention offer are fast and safely escaped, using open tubular column
End setting with slideway integrated design, formed by integrally casting reinforced concrete, pitch angle alpha≤32 ° of slideway, slideway buffers sand pit,
Escape personnel can be snapped down to the escape of buffering sand pit through slideway safely, quickly.
To achieve the above object, the technical solution adopted by the present invention is that, a kind of building are fast and safely escaped spiral slide, packet
An open tubular column for being used to support entire spiral slide and its loading capacity is included, one, which is centered around the open tubular column peripheral surface, helically rises
Prismatic spiral slide, and the buffering sand pit positioned at the spiral slide bottom end；The top closure of the open tubular column, it is hollow
Column is integrally formed with spiral slide, is formed by reinforced concrete whole-casting；The spiral slide includes a bottom plate and and bottom plate
The two side walls being vertically connected, the bottom surface of bottom plate and the medial surface of two side form riding space, in the one side wall of building
