Description

[Detailed Description of the Invention] The present invention relates to improvements in a lid that is installed and cooled in 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 attached to the top surface of the U-shaped gutter is simply fitted into the step formed at the opening of the U-shaped gutter, so when a car passes over the lid, the lid and the U Because there was a gap between the lid and the stepped part of the gutter, the lid sometimes vibrated and produced noise (rattling).

Therefore, in the case of U-shaped gutters installed on roads, etc., a cushioning material such as rubber is attached to the step part to absorb vibrations and prevent noise generation, but this cushioning material has been used for many years. As a result of use, the effect gradually deteriorated due to peeling and abrasion.

This idea was created by focusing on the points mentioned above.
The purpose of this is to fix at least one side edge of the lid body by engaging a locking plate attached to the lid body with a guide hole formed in a U-shaped gutter, and also fix the other side edge with the same structure or support shaft. This U-shaped side gutter lid device is installed with a structure of a bearing and a bearing, so that the lid body does not vibrate even when an automobile or the like passes by, and can prevent the generation of noise.

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 is attached to the lower surface of the upper surface piece 2d by means of 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 screw thread 5a. As shown in FIG.
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 protrusion 8c, into which a lock plate 9 is inserted and rotatably supported in the corner of the space 8e. has been done.

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 described. 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 through the screw thread 5a, and is brought out from the square hole 2c, and the protrusion 8c of the lid body 8 is inserted through the square hole 2c, and the support shaft 8d formed in the protrusion 8c is inserted. 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.

In the above-mentioned embodiment, one side edge of the lid body 8 is rotatable and the other side edge is fixed with a locking plate 9. However, as another method, both edges can be secured with a locking plate 9. 9 may be used to fix it.

As described above, the present invention fixes at least one side edge of the lid body to the opening of the U-shaped gutter by engaging the locking plate and the guide hole formed in the U-shaped gutter, and fixes the other side edge in the same way. Since it is attached by means of a shaft support means that can be opened and closed, the lid body is securely fixed to the U-shaped gutter, and therefore no noise is generated even if a car, etc. passes over the top surface of the lid body. In addition, the lid body and the U-shaped side groove can be easily disengaged from each other.
