Description

  The present invention prevents inundation damage to underground garages and low-rise buildings due to accidental water level rises such as urban floods caused by torrential rain, and blocks high water levels due to river flooding, etc. It is related with the apparatus which prevents this.

  Traditionally, sandbags have been piled up to prevent inundation of buildings due to accidental water level rises such as heavy rain floods. However, sandbags have an average of more than 20 kilograms, and stacking several to dozens of them is a hard work impossible for children. In addition, waterproofing with sandbags was not perfect, and it was difficult to prevent inflow of water into underground structures with sandbags alone. In recent years, metal waterproof boards (tide boards) have begun to appear on the market, but many of the waterproof boards are quite heavy and can be attached and detached except for those that are movable (expensive and have limited installation location). Needed more than one person. Moreover, it was difficult to secure a storage place for a large waterproof board.

Summarizing the above points, the problems of the present invention are as follows.
A. Waterproofing with sandbags requires manpower and time because many sandbags, which are heavy objects, need to be stacked. Also, waterproofing with sandbags is not perfect.
B. Waterproofing with a waterproof plate (tide plate) is a large-scale structure in the power type, and in a general projecting method from the underfloor, a large portion is embedded under the floor, which increases the construction scale and cost. When power is supplied by electricity, most of the substation facilities in the building are underground, and in some cases, the substation facilities have been submerged in the past, and the waterproof sheet did not work. Also, it is difficult to install in places where there is no power source.
C. A metal waterproof board that is detachable requires labor to transport and attach the waterproof board from the storage location to the installation location. In addition, metal waterproof boards are heavy, and many managers such as condominiums are old people with weak power, so it is difficult to carry and install. Thus, a lightweight waterproof device has been demanded.

  In order to solve the above-mentioned problems, the present invention has taken the following measures. First, L-shaped support posts fixed at both ends of the building entrance are provided (FIG. 1), and a metal tube with a lid is embedded in the entrance floor (FIG. 2). The waterproof cloth is intimately fixed to the inner bottom surface of the metal cylinder in advance, and the waterproof cloth can be pulled out and spread by removing the lid (FIG. 3). Attach metal rings for fixing to the left and right sides of the waterproof cloth. There are several metal fittings for holding the ring of waterproof cloth in the vertical direction on the front of the column, and elastic rubber with a water-stopping effect is attached to the left and right of this metal fitting in the vertical direction. ing. A plurality of operation handles are provided on the surface of the support column at right angles to the front, and a U-shaped waterproof metal fitting that is fixed across the ring of waterproof cloth is movably connected and fixed to the tip of the operation handle. .

During waterproofing, pull out the waterproof cloth from the metal cylinder under the floor and hang the retaining ring of the waterproof cloth on the retaining bracket of the support. As a result, the water pressure applied to the waterproof cloth is handled by the retaining bracket of the support column. When the operation handle is operated from 2a to 2b (FIG. 4), the waterproof metal fitting moves from 3a to 3b, and the waterproof cloth is sandwiched between the elastic rubber of the waterproof metal fitting by the lever force and is simultaneously pressed against the front surface and the lower surface of the column. . This prevents flooding. A stopper (FIG. 5) 13 for restricting the movement of the handle is attached to the column so that the operation handle does not return naturally.

  In the present invention, a waterproof device is formed by integrating a structure in which a space between the column and the metal cylinder embedded in the floor is closed with a waterproof cloth. The water to be submerged tries to enter the gap between the waterproof cloth and the elastic rubber from the outside (FIG. 4) (A), but before entering the waterproof device ground, the gaps at a plurality of locations (FIG. 4) (A) (B ) (C) (D) must pass through, and the waterproofing effect is very high.

  The operation method is simple: (1) remove the lid of the cylinder embedded in the floor, (2) spread the stored waterproof cloth and hold it on the left and right columns, and (3) rotate and fix the handle. Most waterproof devices are made of lightweight cloth, and can be operated by weak children and elderly people in case of emergency such as flood.

  Secondly, a U-shaped frame (FIG. 7) in which a metal cylinder embedded in a floor and left and right support columns are integrally formed is provided. Thereby, the waterproof effect of the lower left and right corners of the space closing the entrance is improved (see FIG. 4).

  Third, when it is difficult to embed storage on the floor surface, a method of retrofitting a metal plate, to which a waterproof cloth is closely attached in advance, to the floor (FIG. 8) is provided. Several nuts are embedded in the floor, and the metal plate is attached with bolts with the elastic rubber face down. As a result, the waterproof device can be attached to the floor of the building with minimal scratches.

Fourth, a waterproof cloth is closely attached to the upper part of the metal waterproof board, the metal waterproof board is attached to the support with a crescent, and the waterproof cloth is attached with the retaining ring and the waterproof metal fitting of the present invention. A synthetic usage (FIG. 9) is provided. Detachable metal waterproof board is strong against water pressure and effective for mounting on wide frontage, but because of its increased weight, it can be transported by hand (frontage width x height). There is a limit. If the expected water level of flooding is high, the metal waterproof plates must be stacked in two or three steps, which takes time to install. If a waterproof cloth is combined with a metal waterproof plate, the waterproof cloth can cope with the height of the waterproof water level, and the overall weight of the waterproof device can be reduced. Since the height of the waterproof cloth can be easily changed as long as the length of the support is sufficient, even if there is a change in the expected water damage level, it can be easily handled by replacing the waterproof cloth. By combining the two methods, a building with a wide frontage width is lighter than stacking metal waterproof plates and can be quickly installed, while having strength that is not inferior to water pressure than a waterproof cloth-only type.

  The operation handle attached to the support column moves in a direction perpendicular to the entrance front. When the waterproof device is attached, the tip of the handle protrudes from the support column, which is dangerous for external pedestrians. As a countermeasure, a torque control unit is provided on the handle so that it can be folded. After applying force in the waterproof cloth pressure-contact direction and fixing it, if torque is applied, it can be folded and stored. Thereby, an external pedestrian is not injured by the handle tip.

Hereinafter, the present invention will be described according to examples.
The waterproof device of the present invention has a column 1 and a wall surface of an entrance opening of a building, an underground parking lot, etc., and a column 1 (FIG. 1) and a column 2 manufactured symmetrically with respect to 1 in a direction facing each other. It is composed of a combination of a pair of attached structures and a waterproof cloth (FIG. 3) embedded or exposed on the floor surface of the opening, or a combination of these (FIG. 7).

  The case where the frame type (FIG. 7) which joined the U-shaped cylinder and the support | pillar which accommodated the waterproof cloth, and was integrally molded is demonstrated. The floor of the entrance opening is grooved and suspended, and the frame is embedded. The column and the entrance post or wall surface are attached by welding, bolting, etc. and then waterproof caulking. The support is pre-installed with an operation handle, a U-shaped waterproof metal fitting, and a retaining metal fitting (Fig. 1). The floor of the one-piece frame has a waterproof cloth folded (Fig. 2) and has a lid when not in use.

  Because the water pressure changes to tension, the waterproof cloth is (i) a waterproof cloth made of a strong cloth such as canvas, (b) a cloth-like cloth that can be folded with a thick non-stretchable chemical compound such as vinyl chloride, (C) It can be proposed to use a strong material such as glass fiber or mineral fiber that has been made into a cloth and waterproofed. This waterproof cloth is attached to the inside of a U-shaped tubular body made of a material resistant to rust such as stainless steel, with stainless steel bolts in a state of being sandwiched between elastic rubber. Reinforce the right and left ends of the waterproof cloth and attach several retaining brackets such as riveted rings vertically. (Figure 3)

  When a flood forecast is issued, the building or parking lot manager removes the lid of the waterproof device, spreads the waterproof cloth inside and hangs it on the retaining bracket on the column, and then fixes the operation handle from below. Turn it up to the position where it is fixed by the handle stopper. Then, the waterproof cloth is sandwiched between the elastic rubber by the waterproof metal fittings inside the support column, and the waterproofing treatment is completed.

  This waterproof device is characterized by the strength to sandwich the waterproof cloth with elastic rubber. By attaching two or more handles, it can be operated with both hands, and the force in the direction of crushing the elastic rubber can be increased.

  We propose a waterproof device that automatically pulls out a waterproof cloth from the storage unit using electric power and performs waterproofing and storage operations. The waterproof cloth is fixed to the inner tube 15 of a double cylindrical tube fixed with a spring-shaped metal fitting. The inner tube is rotated by the force of the mainspring 17, and a waterproof cloth is wound in the outer tube 16. (FIG. 10) The waterproof cloth is tightly fixed to the bottom surface of the U-shaped cylindrical object at the lower end. The double cylindrical tube is fixed at both ends to a belt (or a chain) that is rotated by a motor inside the column. The belt moves in the same way inside the left and right struts through a shaft that contacts the U-shaped cylinder. The U-shaped waterproof metal fittings are also interlocked with the gear that is in close contact with the belt.

  When the waterproof cloth is stored, the double cylindrical tube is in the U-shaped cylinder under the floor. (FIG. 11) When the waterproof operation is started, the waterproof cloth is pulled out by the belt lifting the double cylindrical tube by the power of the motor. At the timing when the waterproof cloth is pulled out to the height required for waterproofing, the U-shaped waterproof bracket linked to the belt fixes the waterproof cloth from the double cylindrical tube between the elastic rubber of the support column, and the waterproof operation is completed To do. (FIG. 12) The U-shaped waterproof metal fitting performs a waterproof operation while avoiding the place where the belt and the shaft move. The motor and electrical parts should be installed at the height above the column so as not to be immersed in water.

  The storing operation is performed by reversing the belt. The waterproof cloth is wound and stored by the spring inside the double cylindrical tube. A crank handle 21 or the like can be connected instead of the motor. In this case, although it is manual, the waterproof operation can be simplified and speeded up. You can also expect that your hands will not get dirty.

  The waterproof cloth has a structure that can be easily replaced because the waterproof effect is reduced due to deterioration due to aging, damage due to actual use, etc. (Fig. 3). The waterproof cloth is sandwiched between elastic rubber and metal fittings, and is fixed to the U-shaped groove with a stainless bolt. Remove this and install a new waterproof cloth and elastic rubber. If the elastic rod attached to the support is also replaced at the same time, the full waterproof effect will be exhibited again.

The waterproof device of the present invention is expected to be installed at a subway entrance, an underground parking lot entrance, a building entrance with a basement floor, or the like, but it is also expected that the management of the manager is inadequate because of the outside. In order to avoid the risk of unnecessary mischief, it would be appropriate to cover the support column. (FIG. 13) is a proposal of the cover which covers a support | pillar. Locking this cover will delay the emergency operation, but it also prevents accidents and is left to the manager. In addition, if dust enters the waterproof cloth or U-shaped groove buried under the floor, the dust may get caught between the elastic rubber and the waterproof cloth, which may impair the waterproof effect.

It is a support | pillar solid view of this invention. (At the time of installation, see the entrance from the outside of the building and hit the right side) It is sectional drawing which stored the waterproof cloth of this invention in the U-shaped cylinder. It is a top view in the state where the waterproof cloth was unfolded by the bb line of FIG.
