Description

A kind of and matched scalable accommodation rail of sliding support stair

Technical field

The utility model belongs to building element technical field, more particularly to it is a kind of with sliding support stair are matched stretches Contracting accommodation rail.

Background technique

Handrail is that the component helped is climbed for people positioned at railing or breast board upper end and ladder access side-walls.Its form and selection should Meet people and climb the requirement helped and comfortable feel, meets the requirement as decoration element again.Common hardwood, plastics, reinforcing bar Concrete, terrazzo, marble, mental section production.Balustrade is to be built on stair to guarantee stable structure and using peace Full handrail.For balustrade usually by vertical balustrade stay, it, which can connect, depends on any one of pillar at stair one end Side, or be connected with the continuous intermediolateral column of wall.

Interior stairs handrail helps comfort level when holding in view of people, generally uses wooden handrail, size and human body Scale is related.The feel of plastic handrail is also fine, but durability is poor, is not mostly used now.Metal handrail durability and wear-resisting Property it is fine, can be processed into various shape, using more in public building, the disadvantage is that feel is poor when winter uses, people Generally it is unwilling to touch it.

Since existing banister is all monoblock type, cost of manufacture is higher, and should not replace, column and pedal Connection typically uses built-in fitting in advance, and since railing is fixed by cement, therefore its assembly and disassembly is extremely inconvenient, if replacement, Workload is very big, not only increases the burden of user, but also affects the finishing effect in a whole set of house.Banister is because of design Or construction wrong, people can be allowed to feel inconvenient for use, when serious, may cause human casualty accident.

Now, New Dwelling building is generally tier building, the correct installation of balustrade to the safety of the personnel of moving in very It is important.Hand banisters is a critically important component, is not only played role in decoration to building, and in upper and lower traffic evacuation must Through road, or safety guarantee.But in the residential building being completed, in the prevalence of troubling security risk.

Southwestern China portion and central and west regions are in Eurasian earthquake zone, and east is in circum-Pacific seismic belt, this two the earth Shake band is most active position in the world.Under the extruding of Pacific-oceanic plate, Philippine Sea plate and Indian, Earthquake Faulting Band is very active, and China becomes one of rare more shake countries in the world, and area of providing fortification against earthquakes also has reached territory total area 80%.Almost all of municipality directly under the Central Government, China, autonomous region and save 6 grades or more of seismic activity all occurred, these earthquakes it is main Feature is that frequency is high, distribution is wide, focus is shallow, intensity is big and disaster weight.In recent years, the typical earthquake disaster in China mainly has Sichuan 8.0 grades of earthquakes of Richter scale of Wenchuan, direct economic loss 845,100,000,000, disaster-stricken number are more than 87000 people, be over 60 years I State meets with the most wide one earthquake of earthquake most serious, coverage；On April 14th, 2010, Qinghai Province's Yushu County occur Involve multiple state counties, 7.1 fraction secondary earthquake of Richter scale, due to the factors such as altitude sickness, with a varied topography, natural environment and climate be severe It influences, causes rescue work difficulty huge, this secondary earthquake causes about 2700 people wrecked altogether；Yunnan Province Zhaotong City Ludian County in 2014

Generation on August 3,6.5 grades of earthquakes of Richter scale cause up to ten thousand house collapses, and about 620 people are dead, rainy season A large amount of precipitation and complicated geological conditions caused the serious secondary disaster such as landslide, avalanche.

With the development and the improvement of people's living standards of social productive forces, high building structure develop rapidly and Take on important role in process of modernization.The reinforced concrete frame structure skyscraper knot earliest as China Structure, in occupation of very big ratio in civil buildings.The high building structure of early stage be limited to scientific development situation at that time and The level of economic development can not realize its anti-seismic performance well, be considered reasonably designing in the past and but allow people in earthquake It is greatly disappointed, the especially staircase design of early stage.A large amount of seimic disaster census show that the staircase in building is a large amount of in earthquake The case where appearance is badly damaged or even collapses.When earthquake occurs, improperly staircase setting and earthquake resistant construction harm are serious, Antidetonation " main fire escape " and the effect of " safety island " are difficult to play, and delay or even block the evacuation and rescue of trapped person Work, has been further exacerbated by earthquake disaster.This phenomenon repeatedly occurs in all previous earthquake, and most representative is Wenchuan Shake, before this, people are often that the destruction to frame structure main body is paid close attention to, and has ignored damage of the staircase in earthquake It is bad.It finds in investigation, in existing structural system, is destroyed between the cranked slab stairs of cast-in-situ steel reinforced concrete frame structure most tight Weight.

Stair be slidably connected compared to the stair that anti-formula connects, makes the plasticity of structure more evenly, and can effectively mitigate Using the stress concentration phenomenon of anti-formula connection staircase structure.The anti-formula that releases significantly of slip connection mode connects lower waist slab Diagonal bracing effect, under geological process, biggish tension and compression repeatedly are born in anti-formula connection waist slab lower end in the horizontal and vertical directions Power, it will cause concrete and reinforcing bar in waist slab to reach broken faster under reciprocal stress and fall off and yield stress. The effect of sliding support becomes obviously to be conducive to ductility development of the structure under geological process with the increase of earthquake intensity.

The bottom end of stair is arranged to sliding support by traditional design form, is effectively increased the soft of stair bottom end Property, the constraint in horizontal direction to support is effectively alleviated, use of the sliding support in staircase design both ensure that stair Between rigidity, and lower end and supporting member can be connected by sliding support, be disconnected the action path of horizontal direction power, thus Discharge the moment of flexure at support.Stair and construction platform are separated by traditional integral form and are come, building can be effectively weakened The influence that body structure integrally generates building reduces the destruction that earthquake generates it, and enhancing is when natural calamities such as earthquakes The safety of stair when generation.

Slip connection mode can be effectively improved the stress of staircase, mitigate staircase damage, improve structure ductility The significant effect of performance etc. is a kind of scheme for being worth promoting the use of in RC high-rise frame structure.Sliding support building Ladder has good economic results in society, has a extensive future.

Problem corresponding with sliding support stair is the stair generation horizontal displacement when coming earthquake, but traditional stair Accommodation rail cannot stretch therewith, cause accommodation rail rupture failure, influence the evacuation and rescue work of trapped person.
