Description
Technical field
The utility model relates to building construction technology fields, and in particular to fast-escape spiral slide in a kind of building.
Background technique
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.Changing patented technology although can solve fast-escape problem, but its facility mistake
In complexity, water jet does not use for a long time be easy to cause blocking, can not play the effect of wet and slippery escape, inside and outside shield at all when in use
Column does not use for a long time be easy to cause corrosion, is likely to occur stuck can not rotate in escape and is easy to cause accidental wound to escape personnel
Evil.
Chinese patent CN 201810460263.9 discloses a kind of building and fast and safely escapes spiral slide, and use is hollow
The end setting buffering of column and slideway integrated design, formed by integrally casting reinforced concrete, pitch angle alpha≤32 ° of slideway, slideway is husky
Hole, escape personnel can be snapped down to the escape of buffering sand pit through slideway safely, quickly.The escape spiral of CN 201810460263.9
Slide is only suitable for escaping outside building, when for indoor, since a large amount of dense smokes even sea of fire generated when kindling is equally to escape
Personnel damage.

Accommodating cavity communicates.
Further, the fire-fighting spraying head is uniformly set to the top of spiral slide, each fire-fighting spraying head at intervals
Bottom surface away from spiral slide is equidistant.It can make the entire spiral slide of shower water uniform fold, lowering temperature uniform prevents local temperature
Spend height burn escape personnel and reduce slideway mechanical property.
Further, the spacing of the fire-fighting spraying head is 0.5~1 meter, and the distance away from slideway bottom surface is 1.5 meters.Spray
Good cooling effect is drenched, and does not interfere the best-effort path of escape personnel.
Further, the open tubular column and slideway are integrally formed, and are poured by armored concrete, fire-fighting sprays head and passes through
Built-in pipe is set on open tubular column, and built-in pipe is radially embedded in the side wall of open tubular column, and one end extends to accommodating cavity and accommodating cavity phase
Logical, the other end extends side wall and connect with fire-fighting spraying head and communicate with fire-fighting spraying head.Formed by integrally casting reinforced concrete molding,
The kindling of building fire protection grade height is not easy to collapse, highly-safe and corrosion-resistant.Spray head is connected by built-in pipe, overhauls replacement side
Just.
Further, the fire-fighting sprays head and connect with pre-buried pipe thread seal, and fire-fighting is sprayed and set between head and built-in pipe
There is hand off valve.Stop valve is set as normally opened, and maintenance is closed when replacing spray head, replaces spray head easy-to-operate.
Further, the fire-fighting spraying head is closed nozzle, is voluntarily opened when temperature is more than setting value after kindling.Escape
The raw time is shorter, and spray head voluntarily opens more the personal safety that can guarantee escape personnel.
Further, the open tubular column is equipped with pressure gauge, and pressure gauge is used to show the hydraulic pressure in open tubular column.Building are general
Higher, the hydraulic pressure in open tubular column must reach the function of centainly requiring the cooling fire extinguishing of spray head competence exertion, and pressure gauge is arranged, and see
The pressure of pressure gauge is examined, discovery in time is because the phenomenon that hydraulic pressure, on-call maintenance guarantees spray head in the reasons such as leakage reduction open tubular column
Normal use.
The utility model has the beneficial effects that fast-escape spiral slide, use are hollow in building disclosed by the utility model
Column and spiral slide are integrally designed, and open tubular column and fire extinguisher canvas hose are connected, and normal condition keeps being full of certain pressure in open tubular column
Fire water, uniformly distributed fire-fighting spraying head above spiral slide automatically turns on when fire carrys out interim fire-fighting spraying head, can put out a fire, drench
Wet body reduces temperature, prevents from burning, and can also drench towel and cover mouth and nose, every layer of sliding speed only has when spiral stairway is escaped
About 4 seconds, safety was very high.
