Description

The present invention relates to a temporary construction fence, for example installed on a railway platform, and a method for using the same.

The temporary fencing disclosed in Patent Documents 1 and 2 is known as a temporary fencing for construction work that is set up on railway platforms. This temporary fencing is a facility for surrounding the perimeter of a construction area that includes the construction site and material storage area, and is set up on the platform for the purposes of ensuring the safety of passengers getting on and off and preventing theft of materials.

JP 2020-165091 A JP 2016-050422 A

However, if the aforementioned construction area extends along the length of the platform, the temporary fencing surrounding it will narrow the space available for passengers to pass through and wait on the platform. This creates a problem in that passengers cannot get on and off smoothly, especially during peak times (rush hours) when there are many passengers getting on and off.

In light of these circumstances, the present invention aims to provide a temporary enclosure that can be flexibly adapted to various situations.

Therefore, in the first aspect of the present invention, the temporary enclosure separates the construction area from the surrounding area. Here, the construction area includes a first area, a second area, and a third area located between the first area and the second area. The temporary enclosure includes a first wall portion separating the first area from the surrounding area, a second wall portion separating the second area from the surrounding area, a first door rotatably attached to the end of the first wall portion facing the third area, and a second door rotatably attached to the end of the second wall portion facing the third area. The first door is rotatable between a first position separating the third area from the surrounding area and a second position separating the first area from the third area. The second door is rotatable between a third position separating the third area from the surrounding area and a fourth position separating the second area from the third area.

The second aspect of the present invention is a method of using the temporary enclosure described above. This method of use includes setting the first door to the first position and the second door to the third position when construction work is being carried out, and setting the first door to the second position and the second door to the fourth position when construction work is not being carried out.

According to the present invention, the rotational positions of the first and second doors can be changed according to various situations, allowing the temporary enclosure to flexibly adapt to the situation.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Figures 1(a) and (b) are each plan views of a temporary fence in the first embodiment of the present invention, and in detail, Figure 1(a) shows the temporary fence in an integrated state, while Figure 1(b) shows the temporary fence in a separated state. Here, Figure 1(a) shows a temporary fence 10 in an integrated state, while Figure 1(b) shows the temporary fence 10 in a separated state into two temporary fences 10', 10".

Platform 1, which is a railway platform, is, for example, an island platform and has platform ends 2 and 3. Here, FIG. 1 shows, as an example, door positions T1 to T6 of a train stopped adjacent to platform end 2.

As shown in FIG. 1(A), a temporary construction fence 10 is provided on the platform 1 as a facility for surrounding the perimeter of the construction area S0 extending in the extension direction X. The temporary fence 10 separates the construction area S0 from the surrounding area Ss. Here, the construction area S0 includes a construction site and/or a material storage yard. Examples of construction work carried out in the construction area S0 include new construction work such as escalators and elevators, or pile driving work. However, the construction work carried out in the construction area S0 is not limited to these.

The construction area S0 is divided into three or more (three in this embodiment) along the aforementioned extension direction X. In this embodiment, the construction area S0 includes a first area S1 located on one side, a second area S2 located on the other side, and a third area S3 located between the first area S1 and the second area S2. Note that in this embodiment, the construction area S0 and the first area S1, second area S2, and third area S3 that constitute it each have a rectangular shape in a plan view, but these shapes are not limited to a rectangular shape.

In this embodiment, the length L1 of the first area S1 and the length L2 of the second area S2 are each, for example, within a range of 7 m to 12 m. Furthermore, the length L3 of the third area S3 is, for example, within a range of 2 m to 5 m. However, these lengths L1 to L3 are not limited to the aforementioned lengths.

The temporary enclosure 10 has a first wall 11, a second wall 12, a first door 21, and a second door 22. The height of the temporary enclosure 10 is, for example, within the range of 1.5 m to 3 m.

The first wall 11 separates the first area S1 from the surrounding area Ss, and is, for example, U-shaped in plan view. The first wall 11 is composed of a pair of walls 111, 112 that face each other across the first area S1, and a wall 113 that connects the ends of the walls 111, 112 on the opposite side to the third area S3.

The second wall portion 12 separates the second area S2 from the surrounding area Ss, and is, for example, U-shaped in plan view. The second wall portion 12 is composed of a pair of walls 121, 122 that face each other across the second area S2, and a wall portion 123 that connects the ends of the walls 121, 122 on the opposite side to the third area S3.

In this embodiment, the first door 21 is a double-door (double door) with one door 211 and the other door 212. The doors 211 and 212 are rotatably attached to the ends 11a and 11b of the first wall 11 on the third area S3 side (the ends of the walls 111 and 112 on the third area S3 side), respectively.

The first door 21 (doors 211, 212) can be rotated between a first position (see FIG. 1(A)) separating the third area S3 from the surrounding area Ss, and a second position (see FIG. 1(B)) separating the first area S1 from the third area S3.

In this embodiment, the second door 22 is a double-door (double-door) with one door 221 and the other door 222. The doors 221 and 222 are rotatably attached to the ends 12a and 12b of the second wall 12 on the third area S3 side (the ends 121 and 122 on the third area S3 side).

The second door 22 (doors 221, 222) can be rotated between a third position (see FIG. 1(A)) separating the third area S3 from the surrounding area Ss, and a fourth position (see FIG. 1(B)) separating the second area S2 from the third area S3.

As shown in FIG. 1(A), in the integrated temporary enclosure 10, one door 211 of the first door 21 and one door 221 of the second door 22 are connected, and the other door 212 of the first door 21 and the other door 222 of the second door 22 are connected, so that the first door 21 and the second door 22 separate the third area S3 from the surrounding area Ss.

On the other hand, as shown in FIG. 1(a), when the two temporary enclosures 10', 10" are separated, one door 211 and the other door 212 of the first door 21 are connected, and one door 221 and the other door 222 of the second door 22 are connected, so that the third area S3 and the surrounding area Ss are connected. At this time, the first door 21 and the second door 22 face each other with the third area S3 in between.

Here, the temporary fence 10' has a first wall portion 11 and a first door 21. The temporary fence 10" has a second wall portion 12 and a second door 22. The temporary fence 10' surrounds the perimeter of the first area S1. The temporary fence 10" surrounds the perimeter of the second area S2. The height of the temporary fences 10', 10" is, for example, within the range of 1.5m to 3m.

In this embodiment, for example, when construction work is being carried out within the construction area S0, the first door 21 (doors 211, 212) is in a first position (see FIG. 1(A)) separating the third area S3 from the surrounding area Ss, and the second door 22 (doors 221, 222) is in a third position (see FIG. 1(A)) separating the third area S3 from the surrounding area Ss. It is preferable that such an integrated temporary enclosure 10 is formed during off-peak hours when there are relatively few passengers getting on and off the platform 1.

On the other hand, for example, when no construction work is being carried out within the construction area S0, the first door 21 (doors 211, 212) is in the second position (see FIG. 1(a)) separating the first area S1 from the third area S3, and the second door 22 (doors 221, 222) is in the fourth position (see FIG. 1(a)) separating the second area S2 from the third area S3. This separation into temporary enclosures 10', 10" is preferably carried out during peak hours (rush hours) when there are relatively many passengers getting on and off the platform 1. The effect of this will be described later with reference to FIG. 6 and FIG. 7.

Next, the general configuration of the first door 21 and the second door 22 in this embodiment will be described with reference to Figures 2 to 5.

Figure 2 (A) shows the positions of the first door 21 and the second door 22 in the integrated temporary enclosure 10. Figure 2 (B) shows the positions of the first door 21 and the second door 22 in the separated temporary enclosures 10'10". Figure 3 shows the first door 21 and the second door 22 in the integrated temporary enclosure 10, more specifically, a view of the doors 211 and 221 from the third area S3 in the state shown in Figure 2 (A). Figure 4 shows the first door 21 in the separated temporary enclosure 10', more specifically, a view of the doors 211 and 212 from the third area S3 in the state shown in Figure 2 (B). Figure 5 is a cross-sectional view taken along line A-A in Figure 4. Here, Figures 2 (A) and 3 correspond to the aforementioned Figure 1 (A), and Figures 2 (B), 4, and 5 correspond to the aforementioned Figure 1 (B).

In the present embodiment shown in Figures 2 to 5, the width Lw of the construction area S0 (the width of each of the first to third areas S1 to S3) is different from the length L3 of the third area S3. In particular, in the present embodiment shown in Figures 2 to 5, the width Lw is greater than the length L3. To accommodate this, in the present embodiment shown in Figures 2 to 5, the width of at least one of the first door 21 and the second door 22 (both in this embodiment) is configured to be changeable.

As shown in Figures 2 to 5, one door 211 constituting the first door 21 includes a rear panel 2111 which is a rectangular plate-like member, a front panel 2112 which is also a rectangular plate-like member, and a sliding mechanism 400.

One side (hanging side) of the rear panel 2111 is rotatably attached to a support 311 via a hinge 15a. This support 311 constitutes the end 11a of the first wall section 11. The lower end of one side and the lower end of the other side of the rear panel 2111 are each provided with wheels 511 (e.g., casters that can swivel horizontally) that can roll on the platform 1. One end of the brace 611 is attached to the upper end of the support 311 via a hinge 612, and the other end is attached to the upper end of the other side of the rear panel 2111.

The front panel 2112 is configured to be able to slide horizontally along the front surface of the rear panel 2111 via a slide mechanism 400. The slide mechanism 400 has rail members 401 provided at the upper and lower parts of the front surface of the rear panel 2111, and rollers 402 that can roll on the rail members 401. The rollers 402 are rotatably attached to one side of the front panel 2112. The rail members 402 are made of, for example, lip channel steel, and extend horizontally. A wheel 512 (for example, a caster that can swivel horizontally) that can roll on the platform 1 is provided at the lower end of the other side of the front panel 2112.

The width of the door 211 can be changed by sliding the front panel 2112 horizontally relative to the rear panel 2111 via the slide mechanism 400.

As shown in Figures 2 and 4, the other door 212 constituting the first door 21 includes a rear panel 2121 which is a rectangular plate-like member, a front panel 2122 which is also a rectangular plate-like member, and a sliding mechanism 410.

One side (hanging side) of the rear panel 2121 is rotatably attached to a support 312 via a hinge 15b. This support 312 constitutes the end 11b of the first wall section 11. The lower end of one side of the rear panel 2121 and the lower end of the other side are each provided with wheels 513 (e.g., casters that can rotate horizontally) that can roll on the platform 1. One end of the brace 613 is attached to the upper end of the support 312 via a hinge 614, and the other end is attached to the upper end of the other side of the rear panel 2121.

The front panel 2122 is configured to be able to slide horizontally along the front surface of the rear panel 2121 via a slide mechanism 410. The slide mechanism 410 has rail members 411 provided at the upper and lower parts of the front surface of the rear panel 2121, and rollers 412 that can roll on the rail members 411. The rollers 412 are rotatably attached to one side of the front panel 2122. The rail members 411 are made of, for example, lip channel steel, and extend horizontally. The lower end of the other side of the front panel 2122 is provided with wheels 514 (for example, casters that can swivel horizontally) that can roll on the platform 1.

The width of the door 212 can be changed by sliding the front panel 2122 horizontally relative to the rear panel 2121 via the slide mechanism 410.

As shown in Figures 2 and 3, one of the doors 221 constituting the second door 22 includes a rear panel 2211, which is a rectangular plate-like member, a front panel 2212, which is also a rectangular plate-like member, and a sliding mechanism (not shown).

One side (hanging side) of the rear panel 2211 is rotatably attached to a support 321 via a hinge 16a. This support 321 constitutes the end 12a of the second wall section 12. A wheel 515 (e.g., a caster that can rotate horizontally) that can roll on the platform 1 is provided at the lower end of one side and the lower end of the other side of the rear panel 2211. One end of the brace 615 is attached to the upper end of the support 321 via a hinge 616, and the other end is attached to the upper end of the other side of the rear panel 2211.

The front panel 2212 is configured to be able to slide horizontally along the front surface of the rear panel 2211 via a slide mechanism (not shown). The configuration of this slide mechanism is similar to that of the slide mechanisms 400 and 410 described above, so a description thereof will be omitted. A wheel 516 (e.g., a caster that can rotate horizontally) that can roll on the platform 1 is provided at the lower end of the other side of the front panel 2212.

The width of the door 221 can be changed by sliding the front panel 2212 horizontally relative to the rear panel 2211 via a sliding mechanism (not shown).

As shown in FIG. 2, the other door 222 constituting the second door 22 includes a rear panel 2221 that is a rectangular plate-like member, a front panel 2222 that is a rectangular plate-like member, and a sliding mechanism (not shown).

One side (hanging side) of the rear panel 2221 is rotatably attached to a support 322 via a hinge 16b. This support 322 constitutes the end 12b of the second wall section 12. The lower end of one side of the rear panel 2221 and the lower end of the other side are each provided with wheels (e.g., casters that can rotate horizontally) that can roll on the platform 1. One end of a brace (not shown) is attached to the upper end of the support 322 via a hinge (not shown), and the other end is attached to the upper end of the other side of the rear panel 2221.

The front panel 2222 is configured to be able to slide horizontally along the front surface of the rear panel 2221 via a slide mechanism (not shown). The configuration of this slide mechanism is similar to that of the slide mechanisms 400 and 410 described above, so a description thereof will be omitted. A wheel (e.g., a caster that can rotate horizontally) that can roll on the platform 1 is provided at the lower end of the other side of the front panel 2222.

The width of the door 222 can be changed by sliding the front panel 2222 horizontally relative to the rear panel 2221 via a sliding mechanism (not shown).

When transitioning from the integrated temporary enclosure 10 shown in FIG. 2(A) to the separated temporary enclosures 10', 10" shown in FIG. 2(B), the doors 211, 212, 221, and 222 are rotated in the rotation direction M1 shown in FIG. 2(A) and the width of each of the doors 211, 212, 221, and 222 is increased.

Conversely, when transitioning from the separated temporary enclosures 10', 10" shown in FIG. 2(B) to the integrated temporary enclosure 10 shown in FIG. 2(A), the doors 211, 212, 221, and 222 are rotated in the rotation direction M2 shown in FIG. 2(B) and the width of each of the doors 211, 212, 221, and 222 is narrowed.

Next, the effects of this embodiment will be described with reference to FIGS.
Figures 6 and 7 show a conventional temporary enclosure 90 and temporary enclosures 10', 10" of this embodiment. Here, Figure 6 shows the train disembarking situation during peak hours when there are relatively many passengers boarding and disembarking on platform 1, with Figure 6(a) showing the conventional temporary enclosure 90 and Figure 6(b) showing temporary enclosures 10', 10". Figure 7 shows the train boarding situation during the peak hours, with Figure 7(a) showing the conventional temporary enclosure 90 and Figure 7(b) showing temporary enclosures 10', 10".

As shown in Figures 6(A) and 7(A), in the conventional temporary enclosure 90 surrounding the perimeter of the construction area S0, passengers P waiting to board the train tend to concentrate at both ends of the extension direction of the temporary enclosure 90 on platform 1 (for example, they tend to concentrate near door positions T1 and T6 of the train stopped adjacent to the platform edge 2), making it difficult for passengers to board and disembark from the train smoothly. Here, the dashed-dotted line F1 in Figure 6(A) shows the flow of passengers disembarking from the train to platform 1. Also, the dashed-dotted line F3 in Figure 7(A) shows the flow of passengers boarding the train from platform 1.

In contrast, in this embodiment, as shown in Figures 6 (a) and 7 (a), by separating the construction area S0 into two temporary enclosures 10', 10", the third area S3, which is part of the construction area S0, can be used as a space for passengers to wait before boarding, allowing passengers to board and disembark from the train smoothly. Here, the dashed-dotted line F2 in Figure 6 (a) shows the flow of passengers disembarking from the train to platform 1. Also, the dashed-dotted line F4 in Figure 7 (a) shows the flow of passengers boarding the train from platform 1.

According to this embodiment, the temporary enclosure 10 separates the construction area S0 from the surrounding area Ss. The construction area S0 includes a first area S1, a second area S2, and a third area S3 located between the first area S1 and the second area S2. The temporary enclosure 10 includes a first wall 11 separating the first area S1 from the surrounding area Ss, a second wall S2 separating the second area S2 from the surrounding area Ss, a first door 21 rotatably attached to the ends 11a and 11b of the first wall 11 on the third area S3 side, and a second door 22 rotatably attached to the ends 12a and 12b of the second wall 12 on the third area S3 side. The first door 21 can be rotated between a first position (see FIG. 1(A) and FIG. 2(A)) where it separates the third area S3 from the surrounding area Ss, and a second position (see FIG. 1(B) and FIG. 2(B)) where it separates the first area S1 from the third area S3. The second door 22 can be rotated between a third position (see FIG. 1(A) and FIG. 2(A)) where it separates the third area S3 from the surrounding area Ss, and a fourth position (see FIG. 1(B) and FIG. 2(B)) where it separates the second area S2 from the third area S3. This allows the temporary enclosure 10 to flexibly respond to various situations by changing the rotation positions of the first door 21 and the second door 22 according to the situation.

In addition, according to this embodiment, the first door 21 and the second door 22 are double-door doors, each having one door 211, 221 and the other door 212, 222. This allows them to accommodate a wider opening (frontage) than a single-door door.

Furthermore, according to this embodiment, the width of one of the doors 211, 221 and/or the width of the other door 212, 222 are configured to be changeable. This allows for flexible response even if the width Lw of the construction area S0 (the width of each of the first to third areas S1 to S3) and the length L3 of the third area S3 are different.

In addition, according to this embodiment, the temporary enclosure 10 is installed on the railway platform (platform 1). Therefore, by dividing the temporary enclosures 10' and 10", especially during peak hours (rush hours), the third area S3 can be used as a space for passengers to wait for boarding.

According to this embodiment, the method of using the temporary enclosure 10 includes setting the first door 21 to the first position (see Figs. 1(A) and 2(A)) and the second door 22 to the third position (see Figs. 1(A) and 2(A)) during construction, and setting the first door 21 to the second position (see Figs. 1(B) and 2(B)) and the second door 22 to the fourth position (see Figs. 1(B) and 2(B)) during no construction. Therefore, when construction is not being performed, the temporary enclosures 10' and 10" can be divided, and the third area S3 can be used as a waiting area for passengers to board.

Figures 8 (a) and (b) are each plan views of a temporary fence in the second embodiment of the present invention, and in detail, Figure 8 (a) shows the temporary fence in an integrated state, while Figure 8 (b) shows the temporary fence in a separated state. Here, Figure 8 (a) shows temporary fence 10 in an integrated state, while Figure 8 (b) shows temporary fence 10 in a separated state into two temporary fences 10', 10".
The points that differ from the first embodiment will be described.

In this embodiment, the first door 21 and the second door 22 are each a single-leaf door. The first door 21 is rotatably attached to the end 11a of the first wall 11 on the third area S3 side (the end 111 on the third area S3 side), and the second door 22 is rotatably attached to the end 12b of the second wall 12 on the third area S3 side (the end 122 on the third area S3 side). It goes without saying that, instead of this, the first door 21 may be rotatably attached to the end 11b of the first wall 11 on the third area S3 side (the end 112 on the third area S3 side) and the second door 22 may be rotatably attached to the end 12a of the second wall 12 on the third area S3 side (the end 121 on the third area S3 side).

The first door 21 can be rotated between a first position (see FIG. 8(a)) separating the third area S3 from the surrounding area Ss, and a second position (see FIG. 8(b)) separating the first area S1 from the third area S3.

The second door 22 can be rotated between a third position (see FIG. 8(a)) separating the third area S3 from the surrounding area Ss, and a fourth position (see FIG. 8(b)) separating the second area S2 from the third area S3.

As shown in FIG. 8(A), in the integrated temporary enclosure 10, the first door 21 and the second door 22 separate the third area S3 from the surrounding area Ss.

On the other hand, as shown in FIG. 8 (a), when the two temporary enclosures 10', 10" are separated, the third area S3 is connected to the surrounding area Ss. In this case, the first door 21 and the second door 22 face each other with the third area S3 in between.

Here, the temporary fence 10' has a first wall portion 11 and a first door 21. The temporary fence 10" has a second wall portion 12 and a second door 22. The temporary fence 10' surrounds the perimeter of the first area S1. The temporary fence 10" surrounds the perimeter of the second area S2.

In particular, according to this embodiment, the first door 21 and the second door 22 are each a single-leaf door. This allows the first door 21 and the second door 22 to have a simple configuration.

Furthermore, according to this embodiment, it is preferable to apply a sliding mechanism similar to that of the first embodiment described above to the first door 21 and/or the second door 22, so that the width of the first door 21 and/or the width of the second door 22 can be changed. This makes it possible to flexibly accommodate differences in the width Lw of the construction area S0 (the width of each of the first to third areas S1 to S3) and the length L3 of the third area S3.

In the first embodiment described above, the width Lw is greater than the length L3, but the width Lw may be smaller than the length L3, or the width Lw and the length L3 may be equal. This is also true in the second embodiment described above.

The widths of the first to third areas S1 to S3 may be equal to each other or may be different from each other. The width of the first door 21 and/or the width of the second door 22 may be changed as appropriate according to the widths of the first to third areas S1 to S3.

It goes without saying that the illustrated embodiments are merely illustrative of the present invention, and that the present invention includes not only what is directly shown in the described embodiments, but also various improvements and modifications made by those skilled in the art within the scope of the claims.
