The inner protrusion 13 is configured such that the main body frame 21 of the evacuation hatch 20 is placed on the inner protrusion 13, that is, the upper surface of the inner protrusion 13 is in contact with the protrusion 23 of the evacuation hatch 20. It is connected to the main body frame 21 by a connecting member 13a such as a sunlock. Specifically, the tip of the inner protruding portion 13 is bent upward to form a bent portion. This bent portion is provided so as to face the inner surface of the side wall constituting the main body frame 21 when the main body frame 21 is placed on the inner projecting portion 13. A through hole is formed through which the material 13a is passed.
In addition, in this embodiment, as shown in FIGS. 3 and 4, for example, the side walls constituting the main body frame 21 other than the one side wall 21a and the tip (bent part) of the inner protrusion 13 , are connected by the connecting member 13a, but the invention is not limited to this.

Further, the mounting member 10 includes a support member 14 that supports the evacuation hatch 20 from below the reinforcing member 26. The support member 14 is attached to one side wall 11a of the cylindrical portion 11. This one side wall 11a is a side wall that faces the outer surface of one side wall 21a (the side wall to which the reinforcing member 26 is attached) of the escape hatch 20, among the four side walls that constitute the cylindrical portion 11.
The support member 14 includes a joint plate portion 14a that is in contact with the inner surface of the one side wall 11a (the surface on the center side of the opening 30a), and an upper side plate that extends from the upper end of the joint plate portion 14a toward the inside (the center side of the opening 30a). This member has a U-shaped cross section and includes a portion 14b and a lower plate portion 14c extending inward from the lower end of the joining plate portion 14a.

It is connected to the reinforcing member 26 by a filler material 27. Specifically, a through hole 14d through which the fitting material 27 is passed is formed in the upper plate portion 14b.
In this way, by passing the fitting material 27 through both the through hole of the second plate part 26b and the through hole 14d of the upper plate part 14b, the positional deviation of the reinforcing member 26 with respect to the supporting member 14 (especially in the front-back direction) can be prevented. (misalignment) can be prevented. This increases the effect of suppressing the deformation of the one side wall 21a (especially the deformation in the front-back direction) by the reinforcing member 26, so that the flapping of the main body frame 21 that may occur when the evacuation ladder 24 is lowered can be effectively suppressed. It is possible to suppress it.

The mounting member 10 is fixed to the outdoor floor part 30 by driving a fixing member 15 from the inner surface of the side wall forming the cylindrical part 11 toward the core material (frame material 31a) forming the floor body 31.
For example, a coach bolt is used as the fixing member 15, and is passed through each through hole 11b formed in the four side walls of the cylindrical portion 11. The fixing material 15 penetrates the first base plywood 34 and the two-ply fireproof surface material 32, and is driven toward the frame material 31a, which is the core material of the floor body 31.

On the other hand, in the mounting member 10 of the present embodiment, the outer projecting portion 12 projects at right angles to the side wall forming the cylindrical portion 11, and the inner projecting portion 13 also forms the cylindrical portion 11. It overhangs at right angles to the side wall. Therefore, when the cylindrical part 11 is fitted into the opening 30a and the outer projecting part 12 is placed on the outdoor floor 30, the distance between the side surface of the opening 30a and the side wall forming the cylindrical part 11 may vary depending on the location. It will be different.

Specifically, in this embodiment, since the upper surface of the heat insulating panel 33 is sloped downward from the rear side (indoor side) to the front side (outdoor side), for example, as shown in FIG. The distance between the indoor side of the side walls of the opening 30a and the indoor side wall (one side wall 11a) of the side walls constituting the cylindrical portion 11 gradually narrows downward, and The distance between the outdoor side surface and the outdoor side wall of the side walls forming the cylindrical portion 11 gradually increases downward. In this embodiment, an adjusting material 16 whose thickness is appropriately adjusted is arranged between the through hole 11b and the outdoor floor part 30 so that this state is maintained even when the fixing material 15 is driven in.
As a result, even when the fixing material 15 is driven in, the state in which the outer projecting portion 12 and the cylindrical portion 11 are perpendicular to each other and the inner projecting portion 13 and the cylindrical portion 11 are perpendicular to each other is maintained. Further, in the evacuation hatch 20 of the present embodiment, the flange portion 22 protrudes at right angles to the side wall forming the main body frame 21, and the protruding portion 23 also extends at right angles to the side wall forming the main body frame 21. It's sticking out. Therefore, the evacuation hatch 20 of the present embodiment is installed on the outdoor floor 30 with the top surface of the flange portion 22 being approximately parallel to the top surface of the heat insulating panel 33, but the invention is not limited to this, for example. , the upper surface of the flange portion 22 may be installed on the outdoor floor portion 30 in a horizontal state.

Next, an example of an installation procedure for installing the evacuation hatch 20 on the outdoor floor 30 via the mounting member 10 will be described.
First, the outdoor floor section 30 is formed by attaching the fireproof surface material 32, the heat insulating panel 33, the first base plywood 34, the second base plywood 35, the waterproof sheet 36, the draining material 37, etc. to the floor body 31. Two waterproof sheets 36 are provided on the side surface of the opening 30a and the peripheral edge of the opening 30a on the upper surface of the floor body 31.

Next, the mounting member 10 is fixed to the outdoor floor 30.
Specifically, the cylindrical portion 11 of the mounting member 10 is fitted into the opening 30a of the outdoor floor 30, and the outer projecting portion 12 of the mounting member 10 is placed on the outdoor floor 30. Then, the adjusting material 16 is inserted between the surface of the outdoor floor section 30 (waterproof sheet 36) and the through hole 11b of the cylindrical section 11, and the adjustment material 16 is inserted between the surface of the outdoor floor section 30 (waterproof sheet 36) and the through hole 11b of the cylindrical section 11. The attachment member 10 is fixed to the outdoor floor portion 30 by driving the fixing material 15 through the adjustment material 16 toward the core material (in this embodiment, the frame material 31a) constituting the floor body 31.

Next, the escape hatch 20 is fixed to the mounting member 10.
Specifically, the body frame 21 of the evacuation hatch 20 is fitted into the cylindrical portion 11 of the mounting member 10, the flange portion 22 of the evacuation hatch 20 is placed on the outer protruding portion 12 of the mounting member 10, and the evacuation hatch is closed. 20 is placed on the inner protrusion 13 of the mounting member 10, and the reinforcing member 26 of the escape hatch 20 is placed on the support member 14 of the mounting member 10. As a result, the outer surface of the side wall constituting the main body frame 21 of the escape hatch 20 faces the inner surface of the side wall constituting the cylindrical portion 11 of the mounting member 10 and the head of the fixing member 15 driven from the inner surface. becomes.
The connecting member 12a connects the flange portion 22 and the outer projecting portion 12, and the connecting member 13a connects the main body frame 21 and the inner projecting portion 13.
Furthermore, after loosening the nuts 25a of the mounting bolts 25 and hooking the evacuation ladder 24 onto the mounting bolts 25, the evacuation ladder 24 is fixed to the main body frame 21 by tightening the nuts 25a.
Further, a sealing material 38 is filled between the tip of the flange portion 22 in the protruding direction and the upper surface (waterproof sheet 36) of the outdoor floor portion 30.

By installing the evacuation hatch 20 as described above, an evacuation route that connects from above to below the outdoor floor section 30 is formed. That is, an evacuation route from the upper floor where the outdoor floor section 30 is provided to the lower floor can be secured.
In this embodiment, the fitting material 27 is fitted into the reinforcing member 26 before the evacuation hatch 20 is placed on the mounting member 10 (before the reinforcing member 26 is placed on the supporting member 14), and in this state, the reinforcing member 26 is fitted into the reinforcing member 26. Although the fitting material 27 is fitted into the through hole 14d of the supporting member 14 by placing it on the supporting member 14, the invention is not limited to this.

According to the mounting structure of the evacuation hatch 20 and the mounting member 10 of this embodiment, the following excellent effects are achieved.
That is, the evacuation hatch 20 includes a flange portion 22 provided to protrude outward, and is installed on the outdoor floor portion 30 via the mounting member 10, and the mounting member 10 is attached to an opening formed in the outdoor floor portion 30. 30a, and an outer protrusion 12 that protrudes outward from the cylindrical part 11 and is placed on the outdoor floor 30. Since the projecting dimension is set to be shorter than that of the flange portion 22, the number of steps formed between the upper surface of the outdoor floor portion 30 and the upper surface of the flange portion 22 is reduced. It becomes one stage. Therefore, compared to a case where the number of steps in the step part is plural, it is easier to reduce the step part formed by installing the evacuation hatch 20 on the outdoor floor part 30 as much as possible. It is possible to improve the appearance of the installed outdoor floor section 30 and to improve safety.

Further, the mounting member 10 is fixed to the outdoor floor section 30 by driving a fixing material 15 from the inner surface of the cylindrical section 11 (the inner surface of the side wall forming the cylindrical section 11) toward the outdoor floor section 30. The escape hatch 20 includes a cylindrical main body frame 21, and the outer surface of the main body frame 21 (the outer surface of the side wall forming the main body frame 21) is connected to the inner surface of the cylindrical portion 11 (the outer surface of the side wall forming the cylindrical portion 11). The fixing member (fixing member 15) is driven from the inner surface of the main body frame 21 because it is supported by the mounting member 10 in a state where it faces the head of the fixing member 15 driven from the inner surface of the side wall (inner surface of the side wall) and the head of the fixing member 15 driven from the inner surface. The head is not in a protruding state.
For example, the evacuation hatch of Patent Document 1 is fixed by driving the driving fixing member from the inner surface of the cylindrical main body frame toward the hatch attachment opening, so that the head of the driving fixing member is inserted from the inner surface of the cylindrical main body frame. It is in an outstanding state. In this way, if a protrusion is formed on the inner surface of the cylindrical body frame, that is, the inner surface of the descent passage, not only will it look good or bad, but it will also cause problems when using the evacuation hatch (when descending the evacuation ladder). Therefore, it is required to reduce the number of protrusions as much as possible.
On the other hand, as in the present embodiment, the evacuation hatch 20 is not directly fixed to the outdoor floor 30 but is fixed via the mounting member 10, so that the protrusion formed on the inner surface of the main body frame 21 Since it is possible to minimize the amount of space, it is possible to improve the appearance of the inside of the descent passage (the space surrounded by the four side walls constituting the main body frame 21) and to improve safety.

In addition, in the mounting member 10 of the present embodiment, the shape of the cylindrical portion 11 is a rectangular tube shape, but is not limited to this, and may be a cylindrical shape as long as it corresponds to the shape of the opening 30a. There may be.
In addition, in the evacuation hatch 20 of the present embodiment, the main body frame 21 has a rectangular cylindrical shape, but is not limited to this, and may have a cylindrical shape, for example, as long as it corresponds to the shape of the opening 30a. It's okay.

The evacuation hatch 20 also includes a flange portion 22 extending outward from the upper end of the main body frame 21, an evacuation ladder 24 fixed to the main body frame 21, and at least the evacuation ladder 24 of the main body frame 21 being fixed. Since the evacuation ladder 24 is provided with a reinforcing member 26 for reinforcing the part (one side wall 21a), it is possible to suppress the flapping of the main body frame 21 (particularly the one side wall 21a) that may occur when the evacuation ladder 24 is lowered.

The mounting member 10 also includes an outer projecting portion 12 that projects outward from the upper end of the cylindrical portion 11 and supports the flange portion 22 of the evacuation hatch 20, and an outer projecting portion 12 that extends inward from the lower end of the cylindrical portion 11 and supports the flange portion 22 of the evacuation hatch 20. The evacuation hatch includes an inner protrusion 13 that supports the main body frame 21, and a support member 14 that is provided at the center of the cylindrical portion 11 in the vertical direction and supports the reinforcing member 26 of the evacuation hatch 20. Therefore, the mounting member 10 supports the escape hatch 20 at three points: the upper end (outer projecting portion 12) and lower end (inner projecting portion 13) of the cylindrical portion 11, and the vertically central portion (support member 14). Therefore, the installation state of the evacuation hatch 20 can be made strong and stable.

Further, since the support member 14 of the mounting member 10 is connected to the reinforcement member 26 with the reinforcement member 26 of the escape hatch 20 placed on the support member 14, positional deviation of the reinforcement member 26 with respect to the support member 14 ( In particular, positional displacement in the front-back direction can be prevented. Therefore, the reinforcing effect of the reinforcing member 26 (the effect of reinforcing the one side wall 21a) is increased, so it is possible to effectively suppress the flapping of the main body frame 21 that may occur when the evacuation ladder 24 is lowered.

In addition, the floor body 31 constituting the outdoor floor section 30 has an upper surface, a lower surface, and a side surface of the opening 30a covered with a waterproof sheet 36, and a space between the side surface of the opening 30a and the waterproof sheet 36 covering the side surface. is provided with a draining material 37 whose lower end protrudes below the outdoor floor section 30, so rainwater etc. can be drained well at the lower edge of the opening section 30a, and the outdoor floor section 30 can improve the waterproof performance of

Further, since the wooden floor body 31 constituting the outdoor floor section 30 has the upper and lower surfaces and the side surfaces of the opening 30a covered with the fire-resistant surface material 32, the outdoor floor section 30 can be reliably provided with fire-resistant performance. In addition, a first base plywood 34 and a second base plywood 35 are provided on the surface side of the fireproof facing material 32, and a waterproof sheet 36 is pasted on the surfaces of the first base plywood 34 and the second base plywood 35. , waterproof performance can be reliably imparted to the outdoor floor section 30.
Further, the mounting member 10 has an outer protruding portion 12 placed on the upper surface of the outdoor floor portion 30, and a direction toward the core material (frame material 31a) constituting the floor body 31 from the inner surface of the cylindrical portion 11. Since the fixing material 15 is fixed to the outdoor floor part 30 by being driven in, the fixing position by the fixing material 15 can be lower than the upper surface of the floor body 31. Therefore, there is no need to form a region above the upper surface of the floor body 31 into which the fixing material 15 is driven, so that the stepped portion formed by installing the evacuation hatch 20 on the outdoor floor section 30 can be made as small as possible. becomes easier.

For example, in Patent Document 1, when attaching a mounting frame member to the upper surface of a balcony floor, it is necessary to cover the mounting frame member with a fireproof board together with the balcony floor in order to impart fire resistance to the mounting frame member. Therefore, there is a desire to install an evacuation hatch with a simpler structure and improve workability.
On the other hand, according to the present embodiment, the mounting member 10 is installed by placing the outer projecting part 12 on the upper surface of the outdoor floor part 30 and fixing the cylindrical part 11 to the floor body 31 with the fixing material 15. To install the evacuation hatch 20, place the flange part 22 on the outer projecting part 12, and connect the upper part (flange part 22) and lower part (of the main body frame 21) of the evacuation hatch 20 with the connecting members 12a and 13a. Since it is only necessary to connect the lower end portion) to the mounting member 10, the escape hatch 20 can be installed with a simpler structure, and workability can be improved.
In addition, since the fixing material 15 is driven into the wooden floor body 31 after passing through the wooden adjustment material 16 and the first base plywood 34, the fixing strength of the mounting member 10 by the fixing material 15 and, by extension, the evacuation hatch 20 are reduced. The mounting strength of the can be increased.

Furthermore, two waterproof sheets 36 are provided between the outer projecting portion 12 of the mounting member 10 and the floor body 31. That is, since a waterproof sheet (second waterproof sheet 36) is further provided between the outer projecting portion 12 and the upper surface (first waterproof sheet 36) of the outdoor floor portion 30, the outer projecting portion 12 and the outdoor floor section 30 can be improved.
Note that instead of (or in addition to) the waterproof sheet (second waterproof sheet 36), a sealing material is provided between the outer projecting portion 12 and the upper surface of the outdoor floor portion 30 (first waterproof sheet 36). In this way, the waterproof performance between the outer projecting portion 12 and the outdoor floor portion 30 may be improved.

Further, in the escape hatch 20, a flange portion 22 is provided to protrude outward from the upper end portion of the main body frame 21. Therefore, for example, compared to the case where the flange portion 22 is provided so as to protrude outward from the lower end portion or the center portion in the vertical direction of the main body frame 21, the vertical dimension of the portion of the main body frame 21 located above the flange portion 22 is reduced. Therefore, the stepped portion formed by installing the escape hatch 20 on the outdoor floor portion 30 can be made as small as possible.
Further, in the mounting member 10, an outer projecting portion 12 is provided to project outward from the upper end of the cylindrical portion 11. Therefore, for example, the cylindrical portion 11 is located above the outer bulge 12 compared to a case where the cylindrical portion 12 is provided to bulge outward from the lower end or the center in the vertical direction of the cylindrical portion 11. Since the vertical dimension of the part can be suppressed, the stepped portion formed by installing the mounting member 10 on the outdoor floor 30 can be made as small as possible, and as a result, the evacuation hatch 20 can be installed on the outdoor floor 30. This makes it possible to make the step portion formed as small as possible.

Furthermore, since a sealing material 38 is filled between the tip of the flange portion 22 in the protruding direction and the upper surface (first waterproof sheet 36) of the outdoor floor portion 30, the flange portion 22 and the outdoor floor portion 30 are It is possible to further improve the waterproof performance between the outer projecting portion 12 and the outdoor floor portion 30.
Further, since the heat insulating panel 33 is provided on the fireproof surface material 32 covering the upper surface of the floor body 31, and the second base plywood 35 is provided on the heat insulating panel 33, It can contribute to improving fire resistance performance.
Moreover, among the waterproof sheets 36 affixed to the first base plywood 34 and the second base plywood 35, the waterproof sheets 36 pasted to the portions through which the fixing material 15 penetrates are two-ply. The waterproof performance of the portion through which the fixing material 15 penetrates can be improved.
