Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pedestrian bridge provided with a shelter at the top.

[Conventional technology and its issues]

Pedestrian bridges usually don't have anything on top, but if you put a roof over it, it becomes like an arcade and protects you from rain and sunlight.

The pedestrian bridge shown in Figures 6 and 7 of JP-A No. 50-152530 has a roof, but when there is a roof on the top like this, the pedestrian bridge itself is located at a high place as an elevated structure. Since roads and sidewalks cross under it, it is important to deal with rainwater from the roof so that it does not fall down.

However, it would be unsightly to simply install gutters for rainwater treatment, and since the pedestrian bridge is a public place, there is a risk that gutters could be damaged due to tampering.

The purpose of this invention is to provide a pedestrian bridge with a shelter that takes into consideration the above circumstances and prevents rainwater from completely falling downward, and in particular, has a good appearance because the downspouts are not exposed, and is safe from being tampered with. It's about doing.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention stores the downspout inside the U-shaped cross-section pillars that are erected at appropriate intervals with the openings facing inward and support the top plate at the top, and The surface is removably closed with a cover plate, and the upper end of the vertical gutter is communicated with a horizontal gutter installed at the end of the top plate, and a horizontal gutter is also provided at the lower end of the waist wall whose upper surface part is inclined outward. The gutter is intended to be connected to the drain pipe installed on the bridge girder.

[Effect]

According to the present invention, rainwater that falls on the top plate flows along this line, is collected in the horizontal gutter, and then reaches the downspout. It then falls down the downspout and is discharged from the drain pipe. In addition, rainwater that hits the waist wall directly flows over the surface of the decorative board, is collected in the gutter, and is discharged from the drain pipe via the piping.

In addition, the downspout is completely housed within the column and is not exposed to the outside, so when inspecting or repairing, you can remove the cover plate from the column and look into the interior of the column, allowing you to remove damaged areas.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional front view of the main parts showing an embodiment of the pedestrian bridge of the present invention, and FIG. 2 is a plan view of the entire same. In the figure, 1 is a steel bridge girder on the piers 2.

Both ends of the bridge girder 1 rise up to integrally form a waist wall 1a, and an aluminum sandwich panel 3 filled with hard polyurethane as a core material is pasted on the outer surface as a decorative board. Note that the waist wall 1a has an upper surface inclined outward.

On the bridge girder 1, using the gaps between the waist walls 1a, pillars 4 whose corners are arcuate and have a gate-like shape as a whole are erected at appropriate intervals, and beams 5 are stretched over the top of the pillars 4 to form a roof. The top plate 6 is supported, and this top plate 6 is composed of a central aluminum sandwich panel 6a and polycarbonate plates 6b on both sides thereof. Among these, the aluminum sandwich panel 6a has the role of heat insulation and sound insulation board, and the polycarbonate board 6a has the role of heat insulation and sound insulation board.
b is a transparent plate that acts as a light screen.

A horizontal tub 7 was attached along the beam 5 connecting the ends of the top plate 6.

On the other hand, the pillars 4 and the beams 5 are made of hollow extruded aluminum members, and the pillars 4 have a U-shaped cross section with their openings 4a facing inward, as shown in FIG. Downspout 8 connected to 7
Further, the lower end of the downpipe 8 is connected to a drain pipe 9 built into the lower part of the bridge girder 1.

The opening surface 4a is removably closed by a cover plate 10 made of an aluminum plate.
The length of 0 does not need to span the entire length of the support, and the length of the bridge girder 1
It may be a length corresponding to an appropriate rise length from . Although not shown in the drawings, the support column 4 and the cover plate 10 are connected by forming an engagement groove on one side and an engagement claw on the other side along the edge, or by fixing them with screws.

Reference numeral 11 in the figure indicates a balustrade provided at the upper part of the waist wall 1a so as to protrude slightly inward. Further, a small horizontal gutter 12 is provided outside the bridge girder 1 at the lower end of the waist wall 1a, and this is also connected to the drain pipe 9 through a pipe 13.

In this way, rainwater falling on the top plate 6 flows along this and is collected in the horizontal gutter 7, and further reaches the vertical gutter 8. Then, it falls down the downpipe 8 and is discharged from the drain pipe 9. Further, rainwater that directly hits the waist wall 1a flows on the surface of the aluminum sandwich panel 3, which is a decorative board thereof, is collected in the horizontal gutter 12, and is discharged from the drain pipe 9 via the pipe 13.

Further, the downpipe 8 is housed within the support 4 and is not exposed to the outside; however, in the case of maintenance, inspection or repair, the cover plate 10 is removed and the opening of the support 4 is opened. In this case, workers can work on the bridge girder 1, which is extremely safe.

[Effect of idea]

As mentioned above, the pedestrian bridge with a shelter of the present invention is designed to prevent rainwater from completely falling under the pedestrian bridge when a shelter is provided.
In addition, the downspout for rainwater treatment is housed within the support to prevent it from coming out, which gives it a good appearance and prevents it from being damaged by passersby.

Furthermore, since the cover plate of the support column can be removed on the bridge girder to open the opening surface, inspection and repair of the downspout can be carried out easily and safely.
