Description

[Detailed description of the invention] The present invention relates to a rainwater collection and extraction device between bridge girders.

In bridges, in order to obtain good weather resistance of the hinge bearings and O-Lar bearings at the end of the bridge girder in the presence of girder gaps, rainwater that has entered the girder gaps is collected and the girder It is necessary to derive it outside of Yuma.

The conventionally known rainwater collection and drainage device between girder gaps in bridges is such that a gutter made of a hard metal plate called a catcher is attached to the end of the bridge girder on one span side of the girder gap, and the girder is tilted downward in the shape of a bow. A kite plate made of a hard plate with its lower end facing above the gutter is attached to the end of the bridge girder on the other span side, and the rainwater that has entered the girder gap is collected by the kite plate into the p gutter, and is then transferred through the gutter to the girder gap. It is a technical idea that is derived externally. With this type of conventional equipment, if the girder gap is significantly reduced due to an earthquake, etc., the gutter will be crushed at the end face of the bridge girder. The john joint also needs to be made longer, which is undesirable in terms of strength and the like. This problem can be solved by making the gutter deeper and narrowing the width by one inch, but as the gutter cap is reduced, the blade plate that drains rainwater into the gutter must be lengthened, and the long kite plate is In preparation for the reduction of the gap, it is necessary to have a structure that bends freely, such as dividing a kite plate into a front half and a rear half, and connecting them with a screw, which makes the structure complicated.

The present invention eliminates the shortcomings of the prior art and ensures that rainwater between girder gaps in bridges can be accommodated without increasing the girder spacing or complicating the structure. The purpose is to provide a collection and extraction device.

The bridge girder-to-girder rainwater collection and derivation device of the present invention has rubber-like elasticity in its entirety or at least in its bottom portion, and the left and right walls are made of elastic walls, for example, bellows walls made of rubber-like elastic material. , the front wall of the girder leading to the outside of the girder gap is attached to the end of the bridge girder on one span side of the girder gap, and the rear wall of this part is attached to the end of the bridge girder on the other span side.

According to the present invention, the entire gutter provided between the girder gaps or at least the bottom portion has rubber-like elasticity, and the left and right walls are made of elastic walls such as bellows walls made of rubber-like elastic material. Even if the girder gap of a bridge is significantly reduced due to an earthquake, the width of the bridge will also be reduced accordingly, and therefore the girder gap will not be crushed or crushed at the end of the bridge girder like the gutter of conventional equipment. There is no need to make it unnecessarily large.

Furthermore, in the present invention, the gutter is installed across the end of the bridge girder on one span side of the girder gap and the end of the bridge girder on the other span side, in other words, the gutter is installed with the girder gap closed. Since the girder gap is provided, the guide plate in the conventional device is no longer necessary, and even if the gutter is deepened, the disadvantage of complicating the structure of the guide plate does not arise. In addition, closing the girder gap with the gutter means that the width of the girder gap is larger for the same width, which contributes to improving the gutter's collection and drainage capacity in a simple manner. There is.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, (1) is a gutter, and the part (1) is made of, for example, a 00 mm, OD'', and 1.0 mm cloth.

The whole has rubber-like elasticity. The left and right walls of the gutter (1) are stretchable walls (2) such as bellows walls made of rubber-like elastic material, such as Oo plastic or Ri00 prene cloth.
, (3). Front and rear walls of the gutter (1) (4>, (7)
The walls (2) and (3) can be connected to each other by appropriate means, for example by using plates an, cl) as shown in Fig. 4.5.
This can be done by tightening rivets (2). The connection of the walls (2) and (3) to the bottom of the gutter (1) is the sixth
This can be done by means as illustrated in the figure. In Fig. 6, 03 indicates a connecting part formed at the lower end of the wall (2), (''), and the waist part (13) is sewn to the bottom of the gutter (1) by a sewing machine.

The sewing thread is designated by reference numeral a4. 0 indicates a seal applied to the seam on the top surface of the bottom of the gutter (1) using sewing thread a→, or by overlaying a rubber-like elastic material such as 0 Robbin rubber.

The gutter (1) has a longitudinal width that matches the girder gap (5), and its front wall (4) is connected to the bridge girder (6) on one span side of the girder gap (5).
The rear wall (7) is attached to the end of the bridge girder (8) on the other span side by similar means. Gutter (1) has a cross section of U-shape, V-shape, U-shape...
1" shape or any other arbitrary cross-sectional shape can be applied. The gutter (1) is equipped with a drain pipe (9) at the end, and the drain pipe (9)
), the gutter (1) leads to the outside of the girder space (5).

Not only when the girder gap (5) undergoes normal expansion and contraction due to temperature differences, but also when it expands and contracts abnormally due to earthquakes, etc., the gutter (1)
), the front and rear widths automatically change according to the expansion and contraction changes of the beam gap (5).
