Similar to the first option.

When turning down, slide along the pallet 2F of the upper straight chute bottom plate 2 and the pallet 21B of the middle turning chute bottom plate 21, and position it at the 2A position of the chute chute 21 of the turning section chute. The upper straight ladder chute 20 pallet 2F and the middle turn chute bottom plate support plate 21B are leveled with the upper straight ladder chute and the intermediate turning chute chute 21.

Chute guardrail structure and implementation:

The chute guardrail 2A of the front turn chute 20 is composed of two chute guardrails which are hinged to the sector of the segment chute bottom plate, and a chute guardrail hinged at the rear with the rectangular chute bottom plate; upper end and upper layer The chute guardrail 2A of the straight ladder chute is connected, and the following is in contact with the chute guardrail 2A of the turning section, the chute guardrail 2A of the rear turning section, and the chute guardrail 2A of the lower straight chute.

The three-section turning chute guardrail 2A of the turning chute 7 is implemented in the same manner as the first scheme of the upper straight ladder chute and the lower straight chute. That is, the chute guardrail 2A realizes the guardrail function and linkage by the slide hole 27B under the slide hand 1 and the detachable device 27C, the positioning hole 27D and the lateral positioning wire 27A, and the chute linkage wire rope 27.

According to the third aspect of the present invention, the two configurations of the straight ladder chute can be used, that is, the chute guardrail 2A and the chute bottom plate 2 are hinged and fixed, and the continuous slide turning chute 7 The structure, namely the integral fixed structure and the articulated decomposition structure, constitutes a variety of schemes, which can be combined and set according to the actual conditions of various buildings, so that the "High-rise Fast Escape Slide" becomes a series of products.

The fourth solution of the present invention is a blocking and smoke exhausting device in a staircase, comprising a partition 39, an external ventilation duct 41, a roof exhaust wall exhaust fan and a exhaust fan 42; the partition 39 will be upper and lower layers The middle of the stairs is separated to allow the smoke to rise regularly; the outer wall of the floor has a smoke exhaust port and a smoke exhaust fan 42 connected to the external ventilation duct 41 outside the stair wall. The ventilating duct 41 outside the building is a smoke exhausting pipe which is arranged in the outer space of the building from the bottom floor to the top floor, and when the two ends of the exhaust pipe are opened, a strong air flow is generated in the pipe, and a negative pressure is generated. The flue gas 43 in the corridor can be sucked out, and the exhaust pipe 41 is discharged to the outer space. At the same time, the exhaust fan fan is exhausted due to the negative pressure; the flue gas has a way out, no longer fills the building, and the high building can be greatly reduced. The smoke from the fire gathers the danger of the stairs and is conducive to escape.

In summary, the "High-rise Fast Escape Slide" of the present invention can make escapers convenient, safe, low-level, and fast escape. According to estimates, if a 30-story building is used, the escapers will slide for 3-5 seconds on each floor, then they can slide from the top floor to the bottom floor in about two minutes. If each floor slides three people at the same time, there are more than 100 people evacuated in about two minutes. There are few other escape devices that can be compared. If the invention is used to block the flue gas and the smoke exhaust technology, and the "high-rise fast escape slide" technology, the escape person escapes through the stairs, becoming the safest and most reliable choice.
