Description

The present invention is for floating a wooden house on water by breaking the connection between the foundation and the foundation of the wooden house by the force of water such as a flood in order to prevent the house from being inundated or damaged due to a natural disaster such as a typhoon. It is related to the automatic release device.

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 is placed around the house to build a retaining wall, and sandbags, water stop plates, water stop devices, etc. are installed in case of flood damage at the entrance (gate) of the site. do.
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 in the event of flood or other flood damage, the wooden house can be constructed by automatically breaking the connection between the base of the wooden house and the anchor bolts attached to the foundation concrete. An object of the present invention is to provide an automatic release device for floating on water.

In order to solve such a problem, the invention according to claim 1 is a release device for releasing the connection between the base and the anchor bolt to levitate the wooden house when the wooden house is flooded by water such as a flood. Anchor bolt caps are attached to the tips of anchor bolts attached to concrete, and a pinch-type connecting device consisting of two anchor bolt sandwiching members is attached to the upper surface of the base to fix the base and anchor bolts. Anchor bolts between the cap and the base are sandwiched and fixed by the two anchor bolt sandwiching members, and the anchor bolts and the two anchor bolt sandwiching members are released from the fixing. An external buoyancy member with hardware attached is placed, and the hardware for disconnecting the external buoyancy member that has surfaced due to floods, etc. widens the gap between the two anchor bolt sandwiching members. It is characterized by breaking the bond.

In the invention according to claim 2, in addition to the structure according to claim 1, the sandwiching type connecting device is after two anchor bolt sandwiching members having semicircular holes opened to each other at positions facing the anchor bolts. The ends are fixed at the rotation fulcrum, and springs are placed on both sides of the two anchor bolt sandwiching members. In normal times, the springs hold the two anchor bolt sandwiching members in a closed state. It is characterized by that.

In the invention according to claim 3, in addition to the structure according to claim 1 or 2, in order to release the connection between the base of the wooden house and the anchor bolt, the tips of the two anchor bolt sandwiching members are L to each other. A concave part is formed by notching in the shape, and the upper end of the disconnection hardware is inserted into the concave portion formed into the two anchor bolt sandwiching members, and the connection release hardware is attached to the external buoyancy member. It is characterized by the fact that the semi-circular holes facing each other are widened and the connection is broken by ascending the bolt by the force of water such as a flood and widening the concave part.

According to the invention described in claim 1, when a wooden house is flooded by water such as a flood, an anchor attached to the foundation concrete is used in a release device for releasing the connection between the base and the anchor bolt to raise the wooden house. Anchor bolt caps are attached to the tips of bolts, and a pinch-type connecting device consisting of two anchor bolt sandwiching members is attached to the upper surface of the base to fix the base and anchor bolts, and between the anchor bolt cap and the base. Anchor bolts are sandwiched and fixed by the two anchor bolt sandwiching members, and in order to release the fixation of the anchor bolts and the two anchor bolt sandwiching members, an external metal fitting for disconnection is attached around the base. The buoyancy member was placed, and the metal for disconnecting the external buoyancy member that had surfaced due to floods, etc., widened the gap between the two anchor bolt sandwiching members, thereby disconnecting the anchor bolt from the sandwiching type coupling device. This made it possible to break the bond between the anchor bolts buried in the foundation concrete and the wooden house with a simple structure.

According to the invention of claim 2, the sandwiching type connecting device fixes the rear ends of two anchor bolt sandwiching members having semicircular holes at positions facing the anchor bolts at a rotation fulcrum. At the same time, springs are placed on both sides of the two anchor bolt sandwiching members, and in normal times, the springs hold the two anchor bolt sandwiching members in a closed state, resulting in a simple structure. It has become possible to combine anchor bolts buried in foundation concrete with wooden houses.

According to the invention of claim 3, in order to release the connection between the base of the wooden house and the anchor bolt, the concave portion is formed by notching the tip portions of the two anchor bolt sandwiching members from each other in an L shape. After molding, the upper end of the disconnection hardware is inserted into the concave portion formed into the two anchor bolt sandwiching members, and the disconnection hardware attached to the external buoyancy member is floated by the force of water such as a flood. By widening the concave part, the facing semi-circular holes are widened and the connection is released, which makes it possible to release the connection between the anchor bolts buried in the foundation concrete and the wooden house with a simple structure.
