Description

The present invention is a waterproof door stop mechanism that is installed at entrances and entrances of buildings, subways, underground passages, underground shopping streets, underground parking lots, etc., and prevents inundation into the facility in case of emergency such as heavy rain or flooding It is about.

Further, the present invention provides a waterproofing mechanism for a door and a floor surface in a single door or a double door type waterproof door, and has a simple structure and can be operated by anyone in an emergency. It also has a structure that can greatly reduce maintenance, provide a water stop function, and provide a water stop mechanism for fire doors that have a hull that does not impede barrier-free on the floor surface. is there.

Recently, urban heavy rains have caused disasters in which the basement of buildings, subways, underground passages, underground shopping streets, underground parking lots, etc. are flooded within a short time.

Therefore, there are cases where waterproof doors for disaster prevention are installed at the entrances and exits of buildings in the event of floods, and in the entrances and walks of subways, underground passages, underground shopping streets, underground parking lots, and the like. The waterproof door for disaster prevention is disclosed in the undulating waterproof door disclosed in Japanese Patent Laid-Open No. 9-170382 (hereinafter referred to as Patent Document 1) and in Japanese Patent No. 3326488 (hereinafter referred to as Patent Document 2). There is a sliding door type waterproof door and a single door type waterproof door disclosed in Japanese Patent Laid-Open No. 7-279550 (hereinafter referred to as Patent Document 3).

Thus, the feature of the undulating waterproof door disclosed in Patent Document 1 is that a strong and heavy waterproof door is stored in the floor so as to withstand a large water pressure, and air is used to prevent inundation. Use a cylinder, oil cylinder, or balloon jack to raise and lower the waterproof door from the floor, and keep the waterproof door in contact with the floor-side door or the waterproof rubber used as a cushion for the rising door. Therefore, it forms a waterproof door that prevents flooding.

For undulating waterproof doors, a robust and heavy waterproof door is stored on the floor, and a drive device is required to stand up the heavy waterproof door in the event of a disaster. There is a drawback that a drive device that needs frequent maintenance such as an air cylinder, an oil cylinder, or a balloon jack that needs to be inspected must be used. In addition, the storage part for storing the waterproof door on the floor requires the installation depth and size of the floor because the waterproof door and the drive device such as the air cylinder and oil cylinder are incorporated. In many cases, it is not possible to construct a undulating waterproof door at this point due to space requirements.

Further, the sliding door type waterproof door disclosed in Patent Document 2 is characterized by a sliding door type waterproof door main body, guide pillars standing up and down on the left and right, door-holding pillars, and rails laid on the floor and guiding the door main body. And a sealing mechanism mounted on the door body, and the sealing mechanism simultaneously rotates a plurality of eccentric rollers that are pivotally attached to both ends of the door body via a manual handle on the door body, and is in a closed state. The door body is moved in parallel to the back surface side, and the left and right edges and the lower edge of the door body are sealed in a watertight manner.

The sliding door type waterproof door has a drawback that the installation place is limited because a sleeve of the storage space of the door having the same width as or larger than the opening width of the fire door is required. In addition, the sliding door type fire door has a door sealing mechanism in the door body and has a large weight and a large door thickness. The sliding door type fire door is slid on the door and the door opening. A slide rail that slides and moves the waterproof door is housed in the groove of the base material, and a watertight mechanism such as packing is provided inside the groove of the base material to provide the bottom edge and floor of the waterproof door. It is a waterproof surface. Therefore, the structure of the slide rail and the base material is strong and the width of the groove portion is large, and when the waterproof door is not used, the groove portion of the base material incorporating the slide rail on the floor surface of the opening portion of the waterproof door. Is a factor that hinders barrier-free buildings and facilities. In the example of Patent Document 2, the base material is covered with a cover material or an edge plate is laid for this purpose. However, in the sliding door type waterproof door, the floor-mounted slide rail structure is It is not very suitable for dealing with barrier-free.

Further, the single door type waterproof door disclosed in Patent Document 3 is a single door type that is attached to the door frame so as to be openable and closable via an upper release door frame having two columns and a biaxial hinge. The door body, and a heel mechanism mounted on the door body, the heel mechanism locks the door body to a strut material or a closed state by projecting a heel member to the left and right of the door body, The door body is closely attached to the door frame via a packing by a collar member. At this time, the packing can seal both the left and right side edges and the lower edge of the door in a watertight manner. Although the same applies to the door, the double door type waterproof door is provided with a water stop mechanism at the summing portion between the doors.

Thus, the waterproof door of the single-opening door of Patent Document 3 or the similar double-opening door is rotated 90 degrees from the opening of the door, and each fire door is housed on one or both sleeve walls. In addition, it does not require a large door storage space in the floor surface unlike the undulating waterproof door, and does not require a wide sleeve portion serving as a door storage space like the sliding door waterproof door.

However, waterproof doors such as single doors and double doors need to be configured to maintain the watertightness between the four-sided frame and the door by rotating the door around the hinge and pressing the four-way frame through the packing. The shape of the watertight holding portion inevitably requires an outer frame protruding toward the opening and an inner frame shape portion for fitting the door to form a door stop portion and a watertight holding portion. Therefore, the hulling portion installed on the inner floor surface of the four-sided frame is provided with a hulling portion having a watertight holding mechanism with a step on the floor surface, or a hull made of an outer frame and an inner frame protruding on the floor surface. There is a drawback that the sliding (base material 11, step 11a in Patent Document 3) must be provided.

And the disadvantage of waterproof doors such as single doors and double doors is that the hull portion provided to keep the water tightness on the floor surface protrudes on the floor surface or becomes a step and hinders barrier-free In order to solve this problem, a conventional apparatus as shown in FIG. 7 has been developed.

That is, FIG. 7 is an explanatory view of a waterproof door developed so as not to hinder barrier-free operation, and is a front view from the water pressure application side. In FIG. 7, 50 is a floor surface, 51a and 51b are frame members that form a frame, 52 is an upper frame, 53a and 53b are flush door type waterproof doors, and 54 is a summing portion of the waterproof doors 53a and 53b. , 55a, 55b, 56a, 56b are bearings for heavy door hinges that can pivotally support and open the waterproof doors 53a, 53b. The heavy door hinge bearings 55a, 55b, 56a, 56b Has a hinge rotating portion 57 which is held up and down by hinge bearings.

Thus, a hydraulic device (not shown) is connected to the hinge rotating portion 57 so that it can slide up and down, and the hinge rotating portion 57 is slid downward by the hydraulic device. Accordingly, the lower end portions 58a and 58b of the waterproof doors 53a and 53b are pressed against the floor surface 50 only by the clearance C from the door closed state in FIG. 7, so that the lower end portions 59a and 59b of the waterproof doors 53a and 53b are sealed with water or the like. If the member is installed, watertightness is maintained between the waterproof doors 53a and 53b and the floor surface 50, and the watertight mechanism does not need to be provided with a hull or a step protruding from the floor surface 50. It is said that the floor 50 can be configured flat.

However, in the conventional example shown in FIG. 7, a mechanism for moving the heavy waterproof doors 53a and 53b up and down by a hydraulic device is indispensable, which requires manufacturing costs, and the hydraulic device and the like need to be regularly inspected. Maintenance costs are incurred regularly. Further, the waterproof doors 53a and 53b incorporating a hydraulic device or the like are complicated in structure and cannot be operated by anyone in an emergency, but are called troublesome waterproofing water stop mechanisms for waterproof doors that need to be inspected on a daily basis. Inevitable.
