Abstract

[PROBLEMS] To prevent water pollution caused by heavy rain or a typhoon, and to prevent contamination caused by inflow of muddy water or sludge under the floor of a house.
A watertight seal portion made of a synthetic rubber or the like molded in a hydrophobic sponge shape is provided around the waterstop plate base portion having an opening at the center, and a lid shape for closing the opening portion. Provided is a water stop device composed of a water stop plate. It has a function to prevent inundation in the event of flooding by installing the base at the floor under vent of a house where flooding is expected in advance and closing the opening of the base with a lid-like water stop plate when a flood warning is issued. .

Description

  The present invention relates to a disaster prevention device having a function of preventing underfloor contamination due to sewage or sludge flowing from a ventilation opening under the floor of a house or the like due to a natural disaster such as heavy rain or a typhoon.

  In order to prevent sewage flowing from the underfloor vents in the event of a flood, the reality is that it can only be dealt with by eliminating the underfloor vents themselves or installing the underfloor vents higher than the expected flood level. There was no water stop for the underfloor vent.

  Conventionally, the sewage and sludge flowing from the underfloor vents stays under the floor of the house after the floods have subsided, generating odors and causing pillar rot and floor rot.

  The present invention prevents the inflow of sewage by covering the opening with a detachable water stop plate while maintaining the function of underfloor ventilation. Therefore, we devised as follows.

  Underfloor ventilation vents exist for the purpose of preserving the house by letting natural air through the basic part of the house and encouraging ventilation to suppress the generation of mold and pests due to moisture. It is a fall at the end to block itself.

  Therefore, a removable underfloor ventilation stop water device is provided.

  Attach a plate-shaped water-stop device base that has an opening equal to or slightly larger than the opening of the underfloor ventilation opening from the outside of the underfloor ventilation opening in a watertight state with a hydrophobic rubber seal or the like sandwiched between them.

  Separately, a cover that is one size larger than the opening of the water stop device base is prepared. A sponge-like seal made of hydrophobic rubber or the like is attached to one surface of the lid.

  When carrying out the present invention, the opening of the water-stop device base is attached in a watertight manner with the lid, using a screw or a clamp that can be easily attached to and detached from the base.

  When flooding such as heavy rain or typhoon is expected, the underfloor ventilation opening can be closed with the device of the present invention to prevent inundation. This eliminates the generation of odor from under the floor due to sewage and sludge, protects the foundation of the house from moisture, and helps to preserve the maximum property of the house.

  Made of a rust-proof and durable material such as stainless steel, a water-stop base with an opening larger than the underfloor vent is made, and it is applied to the external foundation concrete of the underfloor vent via a hydrophobic seal such as rubber or caulking. Secure with anchors.

  Separately, prepare a water stop plate (lid) of a size that closes the opening of the water stop base with a material such as stainless steel, and attach it to the water stop plate base with a retaining bracket such as a screw.

  A sponge rubber seal made of a hydrophobic material is affixed in advance to the lid that closes the water stop base of the underfloor vent to make the space between the water stop base and the lid watertight.

  FIG. 1 is an overall view with the underfloor ventilation stop water device of the present invention attached. In this way, the entire device is watertightly attached to the underfloor ventilation opening in the foundation of the existing house, thereby preventing underfloor inundation during floods.

FIG. 2 shows the water stop device base (1) of the present invention. A protrusion (7) is provided to prevent displacement when the lid is attached. As a result, when the lid is attached, the mounting operation can be performed without worrying about dropping.
In FIG. 2, a hydrophobic sponge-like rubber seal or the like (6) is provided on the side where the present invention is attached to the underfloor vent to create a watertight state when the water stop base is attached.

  FIG. 3 shows the water stop device cover (2) of the present invention. It attaches to the water-stop device base of FIG. 2 by the retaining metal fitting (3). A hydrophobic seal (6) such as sponge rubber is provided at a position where the lid portion overlaps the water stop device base to create a watertight state of the lid.

  FIG. 4 is a view in which a water stop device base and a lid are attached. Various kinds of known hardware such as a thumbscrew, a lever handle, and a spring lock can be used for the shape of the retaining metal fitting (3) for fixing.

  In the present invention, the base of the underfloor vent stop water stop device is installed in the house in advance, and in the event of an emergency such as a flood warning due to heavy rain or typhoon, a lid is attached to prevent sewage or sludge from entering the underfloor vent. prevent. Remove the water-stopper cover during normal operation. This does not interfere with the ventilation function of the underfloor ventilation port.

  It is the whole figure (front view) which attached the underfloor ventilation stop water stop device of the present invention to the house.   It is a base (AA sectional view) of the underfloor ventilation stop water device of the present invention.   It is a cover part (AA sectional drawing) of the underfloor ventilation port water stop apparatus of this invention.   It is the figure (AA sectional drawing) which piled up the water stop apparatus base and cover part of this invention.
