DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water control door, and relates to a technology relating to a structure of a water control door used in a sewage treatment plant or the like.

[0002]

2. Description of the Related Art As shown in FIGS. 6 and 7, in a conventional water control door, a door 1 is driven up and down by a spindle (not shown), and guide plates provided on a lower door stop 2 and an upper door stop 3 are provided. 4
This guides the vertical movement of the door 1. When fully closed, the water stop plate 5 fixed to the lower door stop 2 and the water stop plate 6 fixed to the rear surface of the door 1 are pressed against each other by a wedge structure (not shown) to exert a sealing function. At the time of full opening, the upper edge of the door body 1 contacts the stopper 7 provided at the upper end of the upper door stop 3.

[0003]

In such a water control door, each member is mainly made of cast iron, and its weight is large.
For this reason, handling is difficult and it takes time and effort to carry in and install at the time of installation, and the work is difficult. In particular, the difficulty increases as the diameter of the opening increases and the width and height of the door 1 and the door stop 2 increase.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a water control door which is reduced in weight and compact in shape, and which is easy to handle at the time of installation and the like.

[0005]

According to a first aspect of the present invention, there is provided a water control door comprising a frame-shaped door stop, and a door body vertically moving up and down along the door stop. A guide plate disposed opposite to the door stop to guide the side edge of the door body, a guide provided on the side edge of the door body, and a stopper fixed to the door stop and abutting on the guide when fully opened. Things.

[0006] With the above structure, by providing the guide at the side edge of the door, the position where the guide and the stopper are provided can be set to an arbitrary position regardless of the size of the door, and the position of the guide can be set at the lower end of the door. , The position of the stopper can be arranged lower. For this reason, the height of the door stop supporting the stopper can be set low,
The weight of the water control door can be reduced and the shape can be made compact.

According to a second aspect of the present invention, there is provided a door stop having a frame shape, a door body which moves up and down along the door stop, and is arranged to face the door stop to guide a side edge of the door body. It has a guide plate and a stopper which is fixedly arranged at a predetermined distance above the door stop on the frame of the civil engineering structure and which comes into contact with the door when fully opened.

[0008] With the above structure, the stopper can be separated from the door stop and disposed on the skeleton of the civil engineering structure, so that the height of the door stop can be set low, so that the weight of the water control door can be reduced and the shape of the water control door can be reduced. Can be achieved.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the water control door 11 is provided with a frame-shaped lower door stop 14 in a spout 13 formed in a concrete frame 12, and a pair of upper doors on both sides of the lower door stop 14. There are 15 door stops. The lower door stop 14 and the upper door stop 15 are fixed by anchor bolts (not shown) provided on the frame 12.

The door 16 moves up and down along the lower door stop 14 and the upper door stop 15, and is driven up and down by a spindle (not shown) connected to the upper hinge 16a. Lower door stop 1
Guide plates 17 for guiding both side edges of the door body 16 are attached to the upper door stop 4 and the upper door stop 15, and a side edge of the door body 16 is provided with a roll preventing guide 18 and a retaining guide 19 for the door body 16. The position is shifted in the front and back directions. Upper door stop 15
A stopper 20 which comes into contact with the retaining guide 19 when fully opened is fixedly arranged at the upper end of the stopper. The anti-rolling guide 18 is provided near the upper and lower ends of the door 16, and the retaining guide 19 is
6 is provided at an upper and lower middle position.

The rear and lower door stops 14 on both sides of the door body 16
A water blocking plate 21 is provided on both side surfaces of the door 16 so as to be in sliding contact with each other, and wedges 22 are provided at predetermined positions on both side surfaces of the door body 16.
Hereinafter, the operation of the above configuration will be described. Water control door 1
In 1, a door 16 is moved up and down by a spindle (not shown) to open and close the spout 13. At this time, the door body 16 is guided by guide plates 17 provided on the lower door stop 14 and the upper door stop 15 at the side edges, and the roll prevention guide 18 is moved to the door body 16.
To ensure smooth ascending and descending movement.

When the door is fully closed, the water stop plates 21 fixed to the lower door stop 14 and the upper door stop 15 are pressed by the force of the wedge 22 to exert a sealing function. When fully opened, the retaining guide 19 of the door body 11 contacts the stopper 20 provided on the upper door stop 15.

By providing the retaining guide 19 at the side edge of the door 16 in this manner, the position where the retaining guide 19 and the stopper 20 are provided can be set to an arbitrary position regardless of the size of the door 16. That is, the position of the stopper 20 can be arranged lower as the position of the retaining guide 19 approaches the lower end of the door body 16. For this reason, the height of the upper door stop 15 that supports the stopper 20 can be set low, the weight of the water control door 11 can be reduced, and the shape of the water control door 11 can be reduced, and the handling can be easily performed. In the present embodiment, the retaining guide 19 is provided at an intermediate position between the upper and lower sides of the door body 16 so that the height of the upper door stop 15 is reduced to half that of the conventional one, the weight of the water control door 11 is reduced, the shape of the door is reduced, and Door 1 with upper door stop 15 at the time
6 for stable support.

As shown in FIG. 4, a lower door stop base 23 is buried in the mouthpiece 13 of the concrete frame 12 and is arranged in advance, and the lower door stop 14 is fixed to the lower door stop base 23 with bolts 24. It is also possible.

As shown in FIG. 5, a stopper 2 is attached to the civil structure frame 12 at a predetermined distance above the upper door stop 15.
It is also possible to fix and arrange 0 and receive the upper end of the door body 16 when fully opened.

In this case, the height of the upper door stop 15 can be set low by separating the stopper 20 from the upper door stop 15 and disposing the stopper 20 on the skeleton 12 of the civil structure.
The weight of the water control door can be reduced and the shape can be made compact.

Alternatively, an anti-rolling guide 18 and a retaining guide 19 are provided on the side edge of the door body 16 so that the retaining guide 1
It is also possible to receive 9 with a stopper 20.

[0018]

As described above, according to the present invention, the guide is provided at the side edge of the door body, and the stopper which comes into contact with the guide when fully opened is fixedly arranged at the door stop, so that the guide is provided at the side edge of the door body. By arranging the guide portion at the portion, the position where the guide and the stopper are provided can be set to an arbitrary position regardless of the size of the door body, and the position of the stopper can be arranged lower as the guide position approaches the lower end of the door body. . For this reason, the height of the door that supports the stopper can be set low, and the weight of the water control door can be reduced and the shape can be made compact. By separating the stopper from the door stop and arranging it on the skeleton of the civil engineering structure, the height of the door stop can be set low, and the weight of the water control door and the shape can be made compact.
