Description

The present invention relates to a floating wooden house for protecting a house from flooding of a flooded river in order to prevent flooding or damage of the house due to a natural disaster such as a typhoon.

In recent years, due to global warming and environmental changes, precipitation per short time has become much higher than before, and many floods have been seen due to flooding of rivers.
The direct damage to a house due to flooding is underfloor or above-floor inundation of the house.
In particular, in the case of flooding on the floor, not only the damage to household goods and tools but also the loss and collapse of houses caused enormous damage.

In addition, flood damage has also occurred in which sewage flows backward due to the flooded river water, and sewage is ejected from manholes and the like and inundates the inside of the house.

As a measure to prevent such flood damage to houses, etc.
(1) Build a house after embankment of the site and raising the ground of the residential land.
(2) Concrete will be placed around the house to construct a retaining wall, and sandbags, water stop plates, water stop devices, etc. will be installed in case of flood damage at the entrance and exit of the site.
So far, such measures have been taken.

However, even with the above flood countermeasures, there have been many reports of water flooding above the special warning water level displayed on the flood hazard map created by the municipalities and flooding the second floor of the house. ing.

The present invention has been made to solve such a problem, and the floating wooden house is lifted in a state of being substantially horizontal by the power of the flooded river water, and is lifted when the flooded river is drained. An object of the present invention is to provide a restoration device capable of automatically returning a floating wooden house to its original position.

In order to solve this problem, the invention according to claim 1 is to attach an anchor bolt cap having a small hole in the center to the tip of an anchor bolt embedded in foundation concrete, and to attach it to the upper surface of the base of a floating wooden house. , Anchor-type connecting device is attached to fix the base and anchor bolts, and the anchor bolt at the bottom of the anchor bolt cap is sandwiched and fixed by the pinching-type connecting device, and the wire rope is automatically wound around the pinching-type connecting device. The device was attached, the wire rope of the wire rope automatic winding device was inserted into the small hole of the anchor bolt cap and fixed, and in order to release the fixing between the pinching type connecting device and the anchor bolt, a metal fitting for disconnection was attached. External buoyancy members are placed around the foundation, and the external buoyancy members are lifted by the force of water such as floods, so that the hardware for disconnection is released from the connection between the pinch-type connecting device and the anchor bolts, and the floating wooden house. The feature is that the floating wooden house is configured to return to its original position by winding the wire rope by the wire rope automatic winding device when water such as a flood is drawn.

In the invention according to claim 2, in addition to the structure according to claim 1, in order to disconnect the base of the floating wooden house and the anchor bolt, the disconnection hardware attached to the external buoyancy member is water such as flood. Anchor bolts are pinched by ascending with the force of It is characterized in that the facing semi-circular holes formed in the built-in member are widened and the connection is released.

In the invention according to claim 3, in addition to the structure according to claim 1 or 2, the wire rope automatic winding device is attached to the upper surface of a saddle-shaped pedestal attached to the upper part of the sandwiching type connecting device, and an anchor bolt cap is attached. A guide hole for wire rope is opened in the saddle-shaped pedestal just above the small hole, and a small guide roller for guiding the wire rope is attached near the guide hole for wire rope. It is characterized by being configured to automatically wind the wire rope of a floating wooden house that has floated above the water by the force of the spiral spring built into the wire rope automatic winding device when water is drawn. ..

According to the invention of claim 1, an anchor bolt cap having a small hole penetrated in the center is attached to the tip of an anchor bolt embedded in foundation concrete, and the base and the anchor bolt are attached to the upper surface of the base of a floating wooden house. Anchor bolts at the bottom of the anchor bolt cap are sandwiched and fixed by the pinching type connecting device, and the wire rope automatic winding device is attached to the pinching type connecting device to fix the wire. In order to insert the wire rope of the automatic rope winding device into the small hole of the anchor bolt cap and fix it, and to release the fixing between the pinching type connecting device and the anchor bolt, the external buoyancy member to which the metal for disconnection is attached is used as the base. When the external buoyancy member is lifted by the force of water such as flood, the metal for disconnection breaks the connection between the pinch-type connecting device and the anchor bolt, and the floating wooden house is floated and flooded. When water is drawn, the wire rope automatic winding device winds up the wire rope so that the floating wooden house returns to its original position, so that the structure is simple and the cost is low. It has become possible to return the surfaced wooden house to its original position.

According to the invention of claim 2, in order to release the connection between the base of the floating wooden house and the anchor bolt, the connection release hardware attached to the external buoyancy member is floated by the force of water such as a flood to release the connection. By inserting the tip of the metal into the concave part of the tip of the two anchor bolt sandwiching members attached to the sandwiching type connecting device and expanding the concave part, the facing semicircles formed into the anchor bolt sandwiching member. The widening of the holes and the disconnection made it possible to disconnect the anchor bolts buried in the foundation concrete and the wooden house at a simple structure and low cost.

According to the third aspect of the invention, the wire rope automatic winding device is attached to the upper surface of the saddle-shaped pedestal attached to the upper part of the sandwiching type connecting device, and the saddle shape directly above the small hole made in the anchor bolt cap. A guide hole for the wire rope is opened in the pedestal to allow the wire rope to penetrate, and a small guide roller for guiding the wire rope is attached near the guide hole for the wire rope. By using the force of the spiral spring built into the take-up device to automatically wind the wire rope of the floating wooden house that has floated on the water, the wire rope of the floating wooden house is configured to automatically wind up, so that the structure is simple and the cost is low. It has become possible to return a wooden house that has surfaced with water to its original position.
