Description
Technical field
The present invention relates to building construction technology fields, and in particular to fast-escape spiral slide in a kind of building.
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.
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, and when for interior, a large amount of dense smokes even sea of fire generated when due to catching fire is equally to escape
Personnel damage.
Invention content
In order to solve the above technical problems, the present invention provides fast-escape spiral slide in a kind of building, using open tubular column with
Spiral slide is integrally designed, and open tubular column and fire extinguisher canvas hose are connected, and normal condition keeps being full of fire water, spiral slide in open tubular column
Uniformly distributed fire-fighting spraying head above road automatically turns on when fire carrys out interim fire-fighting spraying head, can put out a fire, drench body, reduce temperature,
It prevents from burning, can also drench towel and cover mouth and nose, every layer of sliding speed only has about 4 seconds when spiral stairway is escaped, and safety is very
It is high.
To achieve the above object, the technical solution that the present invention takes is：
Fast-escape spiral slide in a kind of building, including one be used to support the hollow of entire spiral slide and its weight
Column, one is centered around prismatic spiral slide that the open tubular column peripheral surface helically rises, and is located at the spiral slide bottom
The buffering sand pit at end；It is characterized in that, the open tubular column is closed at both ends, form an accommodating cavity in open tubular column, the accommodating cavity with
Fire_fighting pipe network communicates, and fire water is full of in accommodating cavity；The side wall of open tubular column be equipped with several fire-fighting spraying heads, fire-fighting spraying head with
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
The distance of bottom surface away from spiral slide is equal.The entire spiral slide of shower water uniform fold, lowering temperature uniform can be made to prevent 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 is integrally formed with slideway, is 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 communicated with fire-fighting spraying head.Formed by integrally casting reinforced concrete is molded,
Building fire protection grade height, which catches fire, to be not easy to cave in, safe and corrosion-resistant.Spray head is connected by built-in pipe, overhauls replacement side
Just.
Further, the fire-fighting sprays head and is 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 after catching fire is more than setting value.Escape
The raw time is shorter, and spray head voluntarily opens the personal safety that more 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 certain function of requiring the cooling fire extinguishing of spray head competence exertion, and pressure gauge is arranged, sees
The phenomenon that examining the pressure of pressure gauge, finding to reduce hydraulic pressure in open tubular column because of reasons such as leakages in time, on-call maintenance ensure spray head
Normal use.
Beneficial effects of the present invention：Fast-escape spiral slide in building disclosed by the invention, using open tubular column and spiral
Slideway is integrally designed, and open tubular column and fire extinguisher canvas hose are connected, and normal condition keeps the fire water that certain pressure is full of in open tubular column,
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 body, drop
Low temperature prevents from burning, and can also drench towel and cover mouth and nose, every layer of sliding speed only has about 4 seconds when spiral stairway is escaped, peace
Full property is very high.
