Embodiment Construction
[0020] like Figure 1 to Figure 4 As shown, it is a safety escape device for the construction of a super high-rise building core tube according to the present invention, which includes a column 4 and a beam 5, and a diagonal brace 6 is arranged between the column 4 and the beam 5, which is used to reinforce the standard section 1, and the beam 5. A steel ladder 2 is fixedly connected. The steel ladder 2 includes a ladder column 15 and a step 16 connected by welding. The ladder column 15 adopts flat steel, and the step 16 adopts round steel. A connecting piece 8 is provided between the ladder column 15 and the beam 5, the connecting piece 8 adopts angle steel, and the connecting piece 8 is connected to the 1 / 4 and 3 / 4 nodes of the beam 5; the connecting piece 8 is welded on the ladder column 15, and the There is a first bolt hole 11, and the connecting piece 8 is provided with a second bolt hole 12 corresponding to the first bolt hole 11. The first bolt hole 11 and the second b...

The invention discloses a safe escape device for ultra-high-rise building core tube construction, which comprises a construction elevator standard section. The standard section comprises a stand column and a transverse beam; the transverse beam is fixedly connected with a steel ladder; and a retainer is fixedly connected outside the steel ladder. The steel ladder comprises a step stanchion and pedals in welded connection; a connecting piece is arranged between the step stanchion and the transverse beam; and the step stanchion is welded with the connecting piece. A first bolt hole is formed onthe transverse beam; a second bolt hole is formed on the connecting piece; and the first bolt hole and the second bolt hole realize detachable connection between the steel ladder and the standard section through bolts and nuts. The retainer comprises an iron ring and a longitudinal rib; the end part of the iron ring is in a fork shape; a third bolt hole is respectively formed on two forked ends; the two forked ends are clamped on the stand column; the third bolt holes realize detachable connection between the retainer and the steel ladder through bolts and nuts; and the top of the uppermost retainer is provided with a sealed cover. The safe escape device for the ultra-high-rise building core tube construction solves the problem of fire-escaping channels during performing unequal height construction in the ultra-high-rise building core tube by adopting shear walls and floors, and has the advantages of fast escape, convenient construction and low cost.
Description
technical field [0001] The invention relates to a safety escape device for super high-rise building core barrel construction. Background technique [0002] The core barrel construction of super high-rise buildings usually adopts climbing formwork, integral lifting steel platform and other construction techniques, which have the characteristics of fast construction speed, simple operation, good project quality and low cost. However, when these technologies are used for construction, the phenomenon that the floor slab lags behind the construction of the shear wall will occur, thereby causing a problem of a fire escape route. Since the only way for construction workers to go up and down the operation floor is the construction elevator, and the operation floor needs to perform open flame operations such as arc welding and gas cutting, and flammable and explosive gases such as oxygen cylinders and acetylene cylinders, as well as combustible materials such as templates and wood ch...
