Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spiral descent type evacuation device. The device of the present invention is an evacuation device to which Article 25 of the Fire Service Enforcement Ordinance is applied.

[0002]

[Prior art]

 For buildings with a predetermined number of floors or more, a spiral descent type evacuation device (sliding device for evacuation) has been conventionally known as an evacuation facility for emergencies in addition to normal elevating steps such as stairs and elevators.

This type of spiral descent type evacuation device is provided with a sliding surface having a spiral floor structure around a support body standing along the outer wall surface of a building, and this spiral floor slope (hereinafter referred to as a slide). The basic structure is to dispose a handrail and a protective net (louver) along both side walls of the bracket. In addition, it is often the case that steps (stairs) are attached to the slide.

[0004] Therefore, as an overview of the conventional technology, the slide is in communication with the evacuation exits on each floor via a crossover member, and this crossover member is commonly used as a landing on each floor of the step. Hereinafter, this section of the slide is called the landing section, and the area (place) that includes the transition members is called the landing.

Here, the structure in which the slide is interrupted at the landing on each floor, that is, the structure in which the ends of the upstream and downstream slip surfaces are connected to the landing is a slip surface (upstream) → landing → slip surface (downstream) flow. It was supposed to be evacuated in.

On the other hand, the structure in which the slides are continuous from the uppermost floor to the lowermost floor without adopting the above-described structure was an evacuation movement mode in which the passengers board the slide from the landing that is connected to the evacuation exits on each floor.

Regarding the sliding surface (spiral floor structure), a structure having a bottom surface on which a large number of pipes are arranged side by side and spirally descending in the longitudinal direction of the pipe, and a large number of rotatable taper rollers There has been an attempt to reduce sliding friction by making a structure in which (conical rollers) are radially arranged side by side around a support.

[0008]

[Problems to be solved by the device]

 However, in terms of safety, ease of installation, operability, etc., it is required that the slides are continuous from the top floor to the bottom floor so that they can be easily accessed from the landing rather than the structure where the slides are interrupted at each landing. However, the structure of the pipe that spirally descends in the longitudinal direction is insufficient in terms of reducing frictional resistance, and the problem that the taper roller on the entire sliding surface is expensive. was there.

The present invention has been made in view of the above circumstances, and solves the above problems and forms a continuous slide from the top floor to the bottom floor, and connects to the landing on each floor (landing area). The purpose of the section is to provide a spiral descent evacuation device that has high performance and low cost by partially connecting taper rollers.

Here, the formation of the landing section may be partially applied to the existing device, and also has the purpose of providing the existing device as a repair if the safety standard is satisfied.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a spiral descent type evacuation device which is improved by providing a sliding surface of a spiral floor structure around a support member standing upright along the wall surface of a building. The slip surface in the landing section, which is connected to the exit via the transition member, consists of tapered rollers that are radially connected around the support, which is the center of the spiral, and has a slope that allows the spiral descending with deceleration. It is characterized by becoming.

In addition, a sliding surface having a spiral floor structure is provided around a support that is erected along the wall surface of the building, and the continuous sliding surface from the uppermost floor to the lowermost floor is composed of a large number of pipes and taper rollers. In this spiral descent type evacuation device, a spiral floor structure has a structure in which a plurality of pipes are arranged in a radial direction from a support, which is the center of the spiral in each descending section, and spirally descends in the longitudinal direction of the pipe. In the landing section that has a surface and is linked to the evacuation exit on each floor via a crossover member, a sliding surface with a slope that can be decelerated and descended by arranging taper rollers radially around the support is provided. It is characterized by having.

Here, the slip surface of all the sections in each of the spiral descent type evacuation devices may have a spiral inclined floor structure having a positive gradient in the radial direction from the support serving as the spiral center.

Further, the deceleration surface may be provided by changing the slope of the slip surface at the end of the landing section and the descending section upstream thereof in the descending direction or the anti-descending direction.

[0015]

[Action]

 By arranging taper rollers in series on the slip surface of the landing section (boarding gate) on each floor and forming a deceleration surface with a gentle slope in the descending direction or the anti-descending direction, the descending section from the upstream to the landing section The frictional resistance when decelerating and descending (entering) is reduced (eased), and an appropriate decelerated descent state is maintained. It is also possible to transfer safely and easily from the evacuation exit on each floor.

[Effect of device]

 The present invention is configured as described above, and forms a continuous slide from the top floor to the bottom floor, and for the section that connects to the landing on each floor (landing section), taper rollers are partially connected. Since it is set up to decelerate and descend in this section, the frictional resistance (sliding friction) during the descent can be reduced.
