Description

The present invention relates to a technical field of an evacuation door device for a tunnel provided at an evacuation port for evacuating from a roadway through which a vehicle such as an automobile or a railroad passes to an evacuation passage in a tunnel.

Today, with the progress of civil engineering and construction technology, long tunnels have been constructed, and in such long tunnels, evacuation passages (evacuation routes) are provided separately from the roadway through which vehicles pass, and are provided within the roadway. In the event of an emergency such as a fire, evacuees on the roadway can escape to the outside of the roadway by evacuating to the evacuation passage from the evacuation port provided on one side of the roadway in the left-right direction. ..
By the way, in such a tunnel, for example, a side road (observer passage) is formed in which the left and right ends (either one or both of the left and right) of the roadway are raised in a stepped manner, and the observer can walk through this side road. In some cases, the inside of the tunnel is inspected and maintained in this way, but an evacuation port that serves as an entrance to the evacuation passage is formed on such a side road, and an evacuation door that can be opened and closed is provided at the evacuation port. (It is normally closed.) It is possible to evacuate from the roadway to the evacuation passage by opening it.
It has been proposed that such an evacuation door can be opened and closed by a traveling roller provided on the evacuation door by rolling a traveling rail provided on the tunnel skeleton side (see, for example, Patent Document 1).

When such an evacuation door device is installed in a tunnel, the evacuation door runs completely in a straight line because of the construction accuracy of the tunnel itself, the assembly accuracy of the evacuation door device, the construction accuracy, etc. (there is a non-landing state). Not only is it practically difficult to make a configuration that allows for evacuation, but also foreign objects such as pebbles and other jumping objects and scattered objects that are jumped up by vehicles traveling in the tunnel may fall onto the traveling rails, resulting in evacuation. It is difficult to open and close the door in the ideal state (the state drawn in the design drawing), and unintentional resistance to the movement of the evacuation door may occur, or in the vertical, horizontal, and front-rear directions. Furthermore, it is assumed that there is a possibility that smooth opening / closing movement may be hindered due to complicated displacement in the three-dimensional direction in which these are combined, and there is a problem to be solved by the present invention.

A roadway 2 through which vehicles pass is formed, and an evacuation passage (evacuation road) 3 through which people evacuating from the roadway 2 pass is formed in the lower half.
Hereinafter, the direction in which the vehicle passes through the roadway 2 will be referred to as the front-rear direction, and the width direction of the roadway 2 will be referred to as the left-right direction, but the present invention is not limited thereto.

Further, on at least one side of the roadway 2 in the left-right direction (one or both of the left and right sides in the width direction of the roadway 2), a side road (observer passage) on which the observer can move in the front-rear direction along the roadway 2. ) X has an inverted L shape and is formed so as to be stepped higher than the roadway 2, but the side road X is cut out at an appropriate interval in the front-rear direction, and the cut An evacuation door device Z is provided at the notch portion, and an evacuee who evacuates from the upper roadway 2 enters the lower evacuation passage 3 from the evacuation port 5 provided in the evacuation door device Z via the communication passage 6. The evacuation movement is possible, but it goes without saying that the connecting passage 6 may have a structure such as a slide, a staircase, a slope, or the like that allows evacuees to pass through.

An evacuation door device Z in which the present invention has been implemented is provided in this evacuation door device Z in order to open and close the evacuation port 5, and the evacuation door 7 constituting the evacuation door device Z is vertically arranged on the road 2 side. The panel portion 8 and the ceiling panel portion 9 extending from the upper end edge of the vertical panel portion 8 toward the side wall portion 1b side of the tunnel 1 are formed in an inverted L shape when viewed from the front-rear direction. However, as will be described later, the evacuation door 7 is provided with a lower roller 10 provided at the lower end of the vertical panel 8 and an upper roller 11 provided at the tip of the ceiling panel 9 on the skeleton side of the tunnel 1. The evacuation port 5 is opened and closed by rolling the lower rail 12 and the upper rail 13 to guide the movement in the front-rear direction.

The evacuation door device Z is provided with an outer housing (casing) 4 having an inverted L-shape and a hollow shape formed by a vertical plate portion 4a and a top plate portion 4b in a state following the side road X. A portion of the outer housing 4 where the evacuation port 5 is provided is a notch portion 4c, and a machine in which various member devices such as a self-closing device necessary for the evacuation door device Z are arranged before and after the notch portion 4c. Although it is a room (equipment room), one of them is also configured as a door pocket in which the open evacuation door 7 is housed (accommodated) (the evacuation door 7 in the open state in FIG. 2 is a two-point chain line). It is drawn in.).
Then, when a person evacuating from the road 2 touches either the vertical panel portion 8 of the evacuation door 7 or the handle 7a provided on the ceiling panel portion 9 to open the evacuation door 7, the evacuation port 5 opens and evacuates there. A person can evacuate from the opened evacuation port 5 to the evacuation passage 3 via the communication passage 6, but the evacuation door 7 that has been opened and moved is a self-closing device after a predetermined time has passed since it was opened. It has been conventionally known that the evacuation door 7 is closed by the automatic self-closing operation when the evacuation door 7 functions, and details of these structures will be omitted. ..
Although the evacuation door 7 of the present embodiment is a manual opening type, it goes without saying that the evacuation door 7 may be a self-opening type that automatically opens the evacuation door 7 by operating a switch.

In the evacuation door 7, a pair of lower rollers 10 are provided in the front-rear direction at the lower end of the vertical panel portion 8 while being located on the evacuation port 5 side, and the lower rollers 10 are located on the roadway 2 side. The lower rail 12 arranged in the positioned state and arranged on the side edge portion of the partition portion 1a can be rolled in the front-rear direction. Reference numeral 10a is a support shaft of the lower roller 10, and 10b is a bracket attached to the vertical panel portion 8 to support one end of the support shaft 10a.

On the other hand, an upper roller 11 is provided on the tip edge portion of the ceiling panel portion 9 via a bracket 14. In the present embodiment, the upper roller 11 is a horizontal axis roller that rotates with the horizontal axis as a support axis 15a. It is configured to include 15 and a vertical axis roller 16 that rotates with the vertical axis as the support axis 16a.
On the other hand, the bracket 14 is configured as being divided into two by the first and second brackets 17, 18, and the front and rear ends of the first bracket 17 are the side surfaces of the front edge side frame member 9a of the ceiling panel portion 9. It is attached and fixed to the lower surface portion 9c of the mounting bracket 9b projecting from the portion (side surface portion on the road side) via the bolt 17a (through the bolt hole (not shown) provided in the upper plate piece portion 17b from the lower side). The bolt 17a is screwed into a screw hole (not shown) provided in the lower surface portion 9c). In this case, between the lower surface portion 9c of the mounting bracket 9b and the upper plate piece portion 17b having a horizontal plate shape of the first bracket 17, the plate surface is arranged vertically on the first horizontal plate shape. Cushioning material 19 is interposed. Of course, the first cushioning material 19 is provided with a through hole (not shown) into which the bolt 17a is loosely fitted.

A vertical plate-shaped second bracket 18 is attached and fixed to the vertical plate-shaped side plate piece portion 17c of the first bracket 17 via bolts 18a while being arranged on the tunnel side wall portion 1b side. (The bolt 18a penetrating the bolt hole (not shown) provided in the side plate piece 17c from the roadway 2 side is screwed into the screw hole (not shown) provided in the second bracket 18. A second cushioning material 20 having a vertical plate shape with plate surfaces arranged on the left and right is interposed between the side plate piece 17c of the bracket 17 and the second bracket 18. Of course, the second cushioning material 20 is provided with a through hole (not shown) into which the bolt 18a is loosely fitted.
The second bracket 18 is provided with the horizontal axis roller 15 in a state of being located at a lower portion on the substantially central side in the front-rear direction, and the vertical axis roller 16 is provided in a state of being located on an upper portion on one end side in the front-rear direction. Further, in the present embodiment, an upper horizontal axis roller 21 having a horizontal axis as a support shaft 21a is provided while being located at the upper end on the other end side in the front-rear direction.

The first and second cushioning materials 19 and 20 provided in this way are formed of a rubber elastic material in the present embodiment, and absorb the load by elastically deforming. Since the first cushioning material 19 has a horizontal plate shape, it is compressively deformed in the vertical direction, whereby the displacement in the vertical direction can be efficiently cushioned, while the second cushioning material 20 Since it has a vertical plate shape, it is compressed and deformed in the left-right direction, which makes it possible to efficiently cushion the displacement in the left-right direction.
The first and second cushioning materials 19 and 20 of the present embodiment are fixed to the upper plate piece portion 17b and the lower surface portion 9c, and the side plate piece portion 17c and the second bracket 18, respectively, which are sandwiched between them. Therefore, it is configured so that it can be attached and detached independently, which contributes to the improvement of maintainability. However, it is fixed to one of the members to be sandwiched, and further to both members to be sandwiched. The present invention can be carried out even with this configuration.

The top plate portion 4b constituting the outer housing 4 is supported by the tunnel side wall portion 1b via the support metal fitting 1c, but the lower surface of the top plate portion 4b has a tunnel side wall portion 1b rather than the notch portion 4c. A mounting bracket 4d is provided so as to be arranged on the side, and the horizontal axis roller 15, the vertical axis roller 16, and the upper horizontal axis roller 21 constituting the upper roller 11 are guided to the mounting bracket 4d. 13 is provided.
The upper rail 13 has a C-shape with the roadway 2 side open in a side view, and the lower one portion 13a having the upper end edge as a free end becomes the first rail 13a to which the horizontal axis roller 15 is guided, and is in the vertical direction. The intermediate straddle portion 13b becomes the second rail 13b to which the vertical axis roller 16 is guided, and the upper piece portion 13c whose lower end edge portion is a free end regulates the unnecessary upward movement of the upper horizontal axis roller 21. The horizontal axis roller 15 is configured to be a third rail 13c for preventing the first rail 13a from coming off. Incidentally, these rails are integrally formed with the upper rail 13 in the present embodiment, but it goes without saying that they may be provided separately if necessary.

In the embodiment of the present invention configured as described above, in an emergency such as a vehicle fire on the road 2 in a tunnel, an evacuee evacuates from the road 2 to the evacuation passage 3 and the evacuation passage 3 The evacuees can escape from the tunnel through the evacuation port 5, but in that case, the evacuees can use the evacuation port 5 provided at the end of the communication path 6 connecting the road 2 and the evacuation passage 3 to the evacuation passage 6. You can evacuate to the evacuation passage 3 through it.
In this case, the evacuation port 5 closed by the evacuation door 7 is opened by the open movement of the evacuation door 7, but the open movement of the evacuation door 7 constitutes the evacuation door 7. This is executed by the lower roller 10 provided at the lower end of the panel 8 traveling on the lower rail 12 provided at the tunnel partition 1a.

In this structure, the evacuation door 7 has an inverted L-shape including the vertical panel portion 8 and a ceiling panel portion 9 extending from the upper end edge portion of the vertical panel portion 8 to the tunnel side wall portion 1b side. Therefore, the center of gravity is deviated not to the position of the vertical panel portion 8 but to the side of the tunnel side wall portion 1b, and the lower roller 10 cannot run independently. Therefore, the evacuation door 7 can be opened and closed in an independent state by the upper roller 11 provided at the tip of the ceiling panel 9 being supported and guided by the upper rail 13 provided on the tunnel skeleton side. In this case, since the upper roller 11 is attached to the ceiling panel portion 9 via the cushioning materials 19 and 20, for example, the construction accuracy of the tunnel itself, the assembly accuracy of the evacuation door device, and the construction accuracy. The evacuation door 7 cannot be driven in a completely straight line due to such factors, or the vertical axis roller 16 is displaced in the left-right direction (non-landing state) because the second rail 13b is not smooth (flat). Even if the lower roller 10 simply moves in the vertical direction by overcoming foreign matter such as pebbles on the lower rail 12, the upper roller 11 is the tip of the ceiling panel portion 9. Since the evacuation door 7 is provided in the part, the evacuation door 7 is displaced not only in the vertical direction but also in the horizontal direction and the front-rear direction in a complicated three-dimensional manner, and the traveling posture of the evacuation door 7 is disturbed. There is a possibility that careless resistance may occur when traveling with the upper rail 13, or the evacuation door 7 may come into contact with or scratch the outer housing 4. In such a case, the cushioning materials 19 and 20 may be elastically deformed. The cushioning function of the evacuation door 7 is corrected by correcting the disturbance of the traveling posture of the evacuation door 7, and the careless resistance is reduced (reduced) or problems such as contact of the evacuation door 7 with the outer housing 4 occur. Is reduced, and the evacuation door 7 is smoothly opened and closed.

Moreover, in this case, as brackets for attaching the upper roller 11, a first bracket 17 connected to the ceiling panel portion 9 and a second bracket 18 provided with the upper roller 11 and connected to the first bracket 17 As cushioning materials, a first cushioning material 19 interposed between the ceiling panel portion 9 and the first bracket 17, a first bracket 17 and a second bracket 17 are provided. It is configured as having a second cushioning material 20 interposed between the 18 and the first cushioning material 19, and the plate surface of the first cushioning material 19 is arranged in the vertical direction (arranged in a horizontal plate shape). The second cushioning material 20 is subjected to compression deformation in the vertical direction, and the plate surface of the second cushioning material 20 is arranged in the left-right direction (arranged in the shape of a vertical plate), so that the second cushioning material 20 is subjected to compression deformation in the left-right direction. Since the first cushioning material 19 mainly cushions the displacement in the vertical direction and the second cushioning material 20 cushions in the left-right direction in different elastic deformation directions, the ceiling panel portion 9 moves up and down. Even if the first and second cushioning materials 19 and 20 can cushion the cushioning materials 19 and 20 in the three-dimensional direction in which the displacements in the left-right and front-back directions are mixed, the non-landing state and the like can be caused. Even if there is a problem, this will be cushioned and the smooth opening and closing movement of the evacuation door 7 will be promoted.

In this case, the second bracket 18 is provided with not only the horizontal axis roller 15 and the vertical axis roller 16 whose constituent members are the upper roller 11, but also the upper horizontal axis roller 21. The member can be provided as a set of assemblies provided with the rollers 11, and as a result, maintainability is improved when there is an abnormality in the upper roller 11.

It should be noted that the present invention is not limited to that of the above-described embodiment, and the cushioning material is not a single plate-shaped cushioning material, but that of the second embodiment shown in FIG. As described above, an appropriate number of thin plate-shaped cushioning materials 22 and 22a are laminated, and the number of laminated sheets can be appropriately changed according to the site.
When the first and second cushioning materials (plurality of cushioning materials) 19 and 20 are adopted as in the present embodiment, the elastic deformation forces (elastic modulus) of these cushioning materials 19 and 20 are made different. It may be used as a cushion.
Furthermore, as the cushioning material, the wall thickness can be appropriately changed (adjusted) as necessary, such as using a thick wall material, and it is also necessary to use an elastic material such as a coil ammunition or a leaf spring. Can be done.

Incidentally, this embodiment can be implemented for an evacuation door that opens and closes an evacuation door provided in a tunnel, and is not limited to an inverted L-shaped evacuation door as in the present embodiment, but has a glyph shape. It can be applied to evacuation doors of various shapes such as those with a flat plate.
