Description

The present invention quickly blocks mainly inundation risk areas (entrances, wide windows, etc.) of structures such as various buildings, subways, underground malls, underground passages, and underground parking lots, and ensures rapid intrusion of water from the outside. Regarding inundation prevention equipment with a simple structure, lightweight and robust structure to prevent.

In recent years, due to torrential rains and floods in some areas such as urban areas, water has rapidly flowed into structures such as buildings, subways, underground malls, underground passages, and underground parking lots through openings such as entrances and windows. It has been flooded and caused enormous damage.
There is a traditional stacking of sandbags that requires a great deal of manpower and time to prevent the sudden inflow of water from the outside into the openings of such structures.
In addition, as the inundation prevention equipment to be installed in the opening of the above structure from the applicant of the present application, a Makuhari blocking type inundation prevention equipment (: Patent Document 1) in which a flexible waterproof panel is covered in the opening, and horizontal waterproofing Cross-cutting blocking inundation prevention equipment (: Patent Documents 2 and 3) that cuts off the panel by traversing the opening, and a descent-blocking inundation that shuts off the opening by lowering the waterproof panel that is fitted from above. Preventive equipment (: Patent Document 4), waterproof panel can be provided at a low cost with a small number of parts, a simple structure, and a waterproof panel that can quickly block the opening without using a tool. Many waterproof panel type inundation prevention equipment (: Patent Document 5) and the like, which enable a waterproof cover to be installed by using a rail cover used as a side frame, have been developed and introduced.
These conventional inundation prevention equipment have merits and demerits depending on the form of the opening, but it is difficult to mold due to the installation of the drive mechanism of the movable part and the complicated structure such as the traverse guide, the elevating guide, and the fitting groove. There are many total melting points, and these maintenance, as well as a lot of installation work and securing of storage space, require manual work and power drive operation. In addition to economic efficiency, there were some difficulties in weight reduction, handleability, quick blocking of the opening, and the effect of reducing the amount of inflow and inundation.

<Action and effect due to the configuration of the main features of the present invention>
The prevention device of the present invention is a waterproof device that has established workability and efficiency by making the panel mounting frame lightweight and robust and enabling the waterproof panel to be mounted on the panel mounting frame with a quick one-touch operation by the above-mentioned configuration. It is a waterproof device that quickly shuts off and reliably prevents sudden intrusion of running water from the outside.
That is, the waterproof device of the present invention is simple because the first receiving metal fitting, the second receiving metal fitting , and the third receiving metal fitting are welded all around the inner wall surface of the panel mounting frame in the panel mounting frame. It enables short-time manufacturing by spot welding or engagement contact joining, and also reinforces the first, second, and third receiving brackets, and the panel mounting frame is especially thick for waterproof panels. The entire waterproof panel can be fitted into the panel mounting frame extremely quickly and accurately without changing the dimensions of the panel, and the inflow and inundation prevention function is exhibited immediately.

The operation of fitting the entire waterproof panel into the panel mounting frame extremely quickly and accurately will be described in detail in Examples.

Further, the waterproof panel is separated from the panel mounting frame by releasing the lock arm of the lock mechanism from the inside of the panel mounting frame, except to prevent urgent inflow and inundation, and is above the opening or near the side portion. If a storage box is provided and stored in this storage box, the removal handling of the waterproof panel in case of emergency waterproofing becomes extremely efficient, and a quick closure of the opening of the entire device is established.

Therefore, the first, second, and third receiving metal fittings to be installed in the panel mounting frame are long integrated ones and a plurality of short ones are arranged in the longitudinal direction of the frame to stabilize the waterproof panel. Allows support.
Moreover, it is possible to deal with waterproof panels having different thickness sizes only by appropriately changing the specifications of the seat surface and the recessed portion of the receiving metal fitting without changing the size of the panel mounting frame itself.
