Description

The present invention relates to a fixed frame for a wooden house for remodeling an existing wooden house into a raised-floor house in a stable state in order to prevent the house from being flooded or damaged due to river flooding caused by natural disasters such as typhoons. It is.

In recent years, large typhoons have caused rivers to overflow, resulting in frequent damage to houses, where water reaches above the floor level.
In addition, flood damage occurs in which sewage flows back up due to rising river water, causing sewage to gush out from manholes and flood the interiors of homes.

In order to prevent such flooding damage to houses in advance,
(1) Build a house after embanking the site and raising the ground of the residential lot.
(2) Construct a retaining wall by pouring concrete around the house (a wall formed by pouring concrete into a formwork or a wall-like structure using concrete blocks), and at the same time as building a retaining wall at the entrance (gate) of the site. Install sandbags, waterproof sheets, water stop devices, etc. in case of floods or other water damage.
Until now, such measures have been taken.

However, even with the above flood prevention measures in place, there have been many reported cases where the first floor of a house was flooded with water that was higher than the special warning water level indicated on the flood hazard map created by the municipality. ing.

Therefore, the present applicant invented and applied for the "elevated floor construction method" described in Patent Document 1. According to this invention, in a house raising method for hoisting an existing wooden house to a height of two or more stories, multiple mounting holes are drilled in the foundation below the foundation, and all the foundations of the wooden house are simultaneously lifted. To enable support and lifting, multiple H-beams for the trestle were inserted into holes for the trestle formed in the foundation concrete, and multiple steel rods for the trestle were erected at the projecting corners to surround the wooden house. Place the H-shaped steel for lifting on the upper surface of both ends of the H-shaped steel, fix the upper flange of the H-shaped steel for the pedestal and the lower flange of the H-shaped steel for lifting with flange fixing fittings, and then attach them to the H-shaped steel for lifting. It became possible to hoist a wooden house by attaching a pulley to the top of the H-shape lifting steel and winding up the wire rope attached to the pulley with a winder.
