Technical field
The present invention relates to a kind of safe escape device of super highrise building core tube construction.
Background technology
The super highrise building core tube construction adopts the construction of technologies such as climbing form frame, integrally hoisting steel platform usually, has that speed of application is fast, operation is succinct, a good engineering quality, the characteristics that reduce cost.But, when adopting these technology constructions, the phenomenon that floor lags behind shear wall construction can occur, thereby produce the problem of a fire drill.Because constructor's only approach of operation layer up and down is a construction elevator, and operation layer need carry out works with torches such as arc welding and gas cutting, placing combustible materials such as flammable explosive gas such as oxygen cylinder and acetylene cylinder and template, wood chip on the material platform, site operation exists disaster hidden-trouble.In case breaking out of fire, the construction elevator outage is stopped transport, and the core tube construction layer operating personnel can't escape.With regard to the construction status of present domestic super highrise building, rarely have construction enterprises to consider the escape problem of constructor on the shear wall construction layer.
The construction elevator of shear wall construction layer generally adopts the high speed construction elevator of single cage about considering, escape face can be reserved in one or two side of cage (near haul passage one side).If dismountable steel ladder can be installed, in these sides just can be the fire drill that the construction layer operating personnel provides a safety.
Summary of the invention
The object of the present invention is to provide a kind of safe escape device of super highrise building core tube construction, in the time of can solving the breaking out of fire of super highrise building core tube construction layer effectively, the problem of operation layer constructor's escape difficulty.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of safe escape device of super highrise building core tube construction, comprise the construction elevator standard knot, and standard knot comprises column and crossbeam, it is characterized in that: crossbeam is fixedly connected with steel ladder, and the steel ladder outside is fixedly connected with guard ring.
Further, steel ladder comprises the cleat stanchion that is welded to connect and marks time, be provided with connector between cleat stanchion and the crossbeam, cleat stanchion is welded to connect part, and crossbeam is provided with first bolt hole, connector is provided with second bolt hole corresponding with first bolt hole, first bolt hole realizes that by screw bolt and nut steel ladder is connected with the dismounting of standard knot with second bolt hole, and the constructor can rely on the steel ladder escape, and escape is quick, the steel ladder cost is low simultaneously, and dismounting is easy.
Preferably, connector is connected on 1/4 and 3/4 node of crossbeam, is about to steel ladder and is symmetrically distributed on the crossbeam center line, makes crossbeam stressed evenly, avoids producing deformation and influences fixed effect.
Preferably, connector adopts angle steel, and the angle steel cost is low.
Preferably, cleat stanchion adopts band steel, convenient fixing with the guard ring divergent ends of band steel, and cost is low simultaneously.
Preferably, the employing round steel of marking time, the constructor is foot-operated during the convenient steel ladder up and down of round steel, and cost is low simultaneously.
Further, guard ring comprises iron ring and vertical rib, and the iron ring end is forked, be equipped with the 3rd bolt hole on two divergent ends, two divergent ends are sandwiched on the column, and the 3rd bolt hole realizes that by screw bolt and nut guard ring is connected with the dismounting of steel ladder, guard ring and band steel cleat stanchion are fixing reliable, and dismounting simultaneously is easy.
Further, the position of guard ring and crossbeam is corresponding one by one, improves the protection of guard ring to the constructor.
Further, the top of the top guard ring is provided with capping, capping is provided with first pin shaft hole, guard ring is provided with second pin shaft hole corresponding with first pin shaft hole, first pin shaft hole and second pin shaft hole realize that by latch capping is connected with the dismounting of guard ring, and capping can be avoided foreign material to fall the constructor is damaged.
The present invention has solved super highrise building effectively and has examined the fire drill problem of bringing when the core tube adopts shear wall and floor is not contour constructs owing to adopted technique scheme.The present invention has utilized mounted construction elevator standard knot dexterously, and it is carried out local flow improvement, near haul passage one or both sides dismountable steel ladder is installed at it, as passway for escaping; The syndeton of steel ladder, guard ring and capping is safe and reliable, and escape is quick, and easy construction, and cost is also relatively low, is worthy of popularization.
