Description

[Detailed Description of the Invention] The present invention relates to an improvement in a lid body attached to a U-shaped gutter installed at the boundary between a roadway and a sidewalk, and the attachment part between the U-shaped gutter and the U-shaped gutter.

Conventionally, the lid body attached to the top surface of the U-shaped gutter is
Since it is simply fitted into the step formed at the opening of the U-shaped gutter, cleaning the inside of the U-shaped gutter requires lifting and removing the heavy lid, which is difficult to do. It was extremely hard work, not only impossible for women and women, but also difficult for male workers as well.

In addition, the holes in the lid are easily clogged with dirt, and this work must be done after removing the lid from the U-shaped gutter, and the removal must be done while the lid is still on the road surface. As a result, soil removal was a difficult and troublesome task.

This idea was created by focusing on the points mentioned above.
The object is to provide a lid device for a U-shaped gutter, which makes it easy to open and close the lid for the U-shaped gutter, and also allows easy removal of clogging.

Next, an embodiment of the present invention will be described with reference to the drawings.

1 is a U-shaped gutter body (hereinafter referred to as the main body) made of concrete with reinforcing steel bars (not shown) buried inside, and metal concrete receivers 2 and 3 are attached to the upper edge of the opening when forming the main body. It is integrated. Vertical grooves 2b are formed in the vertical pieces 2a of the concrete receiver 2 at several locations (four locations in FIG. 1, at intervals approximately equal to the length of the cover 8, which will be described later), and corners communicating with the vertical grooves 2b. A hole 2c is formed in the top piece 2d. In addition, there are several locations in the concrete receiver 3 (four locations in Figure 1),
a vertical piece 3 at a position substantially corresponding to the longitudinal groove);
An elongated guide hole 3b is formed in a.

4 is a square hole 2c in the concrete receiver 2
A bearing 5 is attached to the lower surface of the upper surface piece 2d by welding or the like with one end aligned with the edge of the square hole 2c, and 5 is a stopper similarly attached to the other edge of the square hole 2c via a hinge 5a. As shown in Figure 3, the top piece 2
It can be placed in two positions: resting on the square hole 2c and resting on the square hole 2c. Reference numeral 6 denotes a cover attached by means such as welding to the back surface of the vertical piece 2a and the upper surface piece 2d of the concrete receiver 2, and is large enough to cover the vertical hole 2b and the square hole 2c as well as the bearing 4. is formed. This is to prevent concrete from entering the vertical hole 2b, square hole 2c, and bearing 4 during concrete pouring.

Reference numeral 7 denotes a cover attached by means such as welding over the back surfaces of the vertical piece 3a and the upper surface piece 3c of the concrete receiver 3, and forms a space on the back side of the guide hole 3b. It should be noted that the upper edge of the guide hole 3b is subjected to a wear-resistant treatment such as hardening, since it is engaged with a locking plate 9 provided on a lid 8, which will be described later.

Reference numeral 8 denotes a metal lid body that can be attached to one or more pieces (two pieces in FIG. 1) of the main body 1 so as to be openable and closable, and includes a staggered vertical plate 8a and the vertical plate 8a.
A horizontal plate 8b is formed to connect between the two. Further, on one long side of the lid body 8, protrusions 8 are provided at intervals equal to the spacing between the bearings 4 of the concrete receiver 2.
c is formed, and a support shaft 8d is formed protruding from one side thereof. Further, an elongated space 8e is formed on both sides of the lid body 8 opposite to the protruding piece 8c, and a lock plate 9 is inserted therein, and the lock plate 9 is rotatably pivoted at a corner of the space 8e. supported.

An arc-shaped engagement portion 9 is provided on the shaft support side of the lock plate 9.
A is formed on the opposite side, and a tube portion 9b that slidably supports the drawer rod 10 is formed on the opposite side. Note that bulges 10a and 10b are provided at both ends of the drawer rod 10.
is formed to prevent the draw-out rod 10 from coming out from the pipe portion 9b.

Next, the assembly method will be explained. First, the main body 1 with the concrete receivers 2 and 3 integrated therein is buried in a desired location so that the concrete receivers 2 and 3 are flush with the road surface. Next, the stopper 5 is rotated by the hinge 5a and is brought out from the square hole 2c. Then, the protrusion 8c of the lid 8 is inserted through the square hole 2c, and the support shaft 8d formed on the protrusion 8c is fitted into the bearing 4. Thereby, the lid body 8 is rotatably attached to the concrete receiver 2. However, in this state, the lid 8 can be easily removed from the concrete receiver 2 by shifting it laterally, so the stopper 5 can be rotated and the square hole 2 can be removed.
Insert into c. Thereby, the lid body 8 will not easily come off from the concrete receiver 2. Then, the lid body 8 is attached via the concrete receiver 2,
When the lid 8 is closed, the opening of the main body 1 is closed.

In this state, when the drawer rod 10 is pulled out and the lock plate 9 is rotated to enter the space 8e of the lid 8, the engaging portion 9a of the lock plate 9 enters the guide hole 3b of the concrete receiver 3 and It is engaged with the upper edge of the guide hole 3b. Therefore, one side edge of the lid 8 is fixed by the engagement between the support shaft 8d and the bearing 4, and the other side edge is fixed by the engagement between the engagement portion 9a of the lock plate 9 and the upper edge of the guide hole 3b. Ru.

Since the lid 8 is supported by one side edge of the main body 1 and can be opened and closed, there is no need to lift the heavy lid 8 when cleaning the inside of the main body 1, and cleaning can therefore be easily performed. In addition, since the lid body 8 is supported at an angle when it is opened, the soil and sand stuck in the lid body 8 can be easily removed by hitting the lid body 8, improving work efficiency. .

In addition, since the lid 8 is fixed to the main body 1 at both side edges while blocking the opening of the main body 1, rattling noise may be generated even if a car or the like passes over the top surface of the lid 8. Never.

Furthermore, since the lid body 8 is composed of a staggered vertical plate 8a and a horizontal plate 8b connecting the vertical plates 8a,
It is less likely to slip when a car or the like passes by.

As mentioned above, in the present invention, the lid body is attached to the opening of the U-shaped gutter so that it is pivotally supported by one side edge.
When cleaning inside a U-shaped gutter, you can simply rotate the lid instead of removing it from the U-shaped gutter as in the conventional method, which improves cleaning work and removes dirt and sand that has become stuck in the lid. Since all you have to do is tap it in the open state, it has the effect of easily and reliably removing dirt, etc. In particular, a bearing is attached to the lower surface of one of the upper surfaces with one end aligned with the edge of a square hole formed on one of the upper surfaces of the concrete receiver, and a support shaft of a protrusion formed on one of the long sides of the lid body is rotated to this bearing. Since the lid is movably supported, when attaching the lid to the U-shaped gutter body so that it can be opened and closed, the tip of the protruding piece of the lid is inserted into the square hole from above the top piece, and then the entire lid is moved sideways. All you have to do is move to
It can be operated without using any tools, has extremely good workability, and has an extremely simple structure.

In addition, when the lid is opened and the back side is turned slightly upward, the protruding piece hits the edge of the square hole, preventing further rotation and leaving the lid in an upright position, making it difficult to remove dirt, etc. It becomes easier to remove.

Furthermore, since the engaging part of the locking plate is adapted to be engaged with the upper edge of the guide hole of the other concrete receiver, the lid body is fixed to the U-shaped gutter body on both long sides, and the lid body Even if a car or the like passes over the top surface, it will not rattle.

Furthermore, by pulling out the drawer rod that is slidably attached to the lock plate, the lock plate can be rotated to disengage the engagement part, and by pulling the drawer rod further, the lid body can be rotated about the support shaft. It can be opened easily.
