Abstract

PROBLEM TO BE SOLVED: To provide a house or a building in which a floating body is provided in a site or a lower part of the building against inundation damage, and a part of the building or the building or the site is lifted at the time of inundation to avoid damage. SOLUTION: The structure of this building is a building structure 1, a guide pillar 2, a foundation (fixed to the ground) 3, an inflow port at the time of inundation 4, an inflow pipe 5 at the time of inundation, an underground water tank 6, and a buoyant body (filled with gas or lightweight solid matter). Etc.) 7, consisting of 12 inside the building. If the surroundings of the building structure are flooded, the water that has flooded from the inundation inlet is collected and stored in the underground water tank via the inflow pipe during flooding to generate the buoyancy of the buoyancy body attached to the lower part of the building structure. The size and specific gravity of the buoyancy body are designed to have the same buoyancy as the combined weight of the building structure and the buoyancy body. [Selection diagram] Fig. 3

Description

The present invention relates to a floating structure building.

Conventionally, a floating structure building that floats by buoyancy when flooded by a tsunami or flood has been proposed. There is also a proposal that the site itself will rise in response to flooding. There is also a proposal that a part of the building will rise in response to the flood.

In rare cases, there are large inundation damages such as river flooding and tsunami that completely destroy the building, and small-scale damages such as underfloor inundation that occurs once every few years. be. In addition, a construction method has been proposed in which a floating body is provided on the site or at the bottom of the building to avoid flood damage, and the building, a part of the building, or the site is lifted during flooding to avoid damage, but each has problems and has not been realized.

We propose an economical construction method in which the building itself rises according to the inundation depth so that it can adapt to large-scale inundation damage caused by river floods and tsunamis and small-scale inundation damage such as underfloor inundation. do. The structure of this building is 1 building structure in each drawing, 2 guide pillars, 3 foundations (fixed to the ground), 4 inundation inlets, 5 inundation inflow pipes, 6 underground water tanks, 7 buoyancy. It consists of a body (filled with gas or lightweight solids, etc.) and inside 12 buildings (partitions, etc. are omitted). If the surroundings of the building structure of 1 are flooded, the water that has been flooded from the inundation inlets of 4 provided around the building is collected and collected in the underground water tank of 6 via the inflow pipe of 5 when flooding, and the building structure of 1 is collected. Generates the buoyancy of the buoyancy body of 7 attached to the lower part. The size and specific gravity of the buoyancy body of 7 are designed to have the same buoyancy as the combined weight of the building structure of 1 and the buoyancy body of 7. Then, the weight of the building disappears when the water tank of 6 is full, and if the site is flooded by 50 cm, the structure of the building of 1 will be lifted by 50 cm, and the damage to the building can be avoided. At that time, since the building does not move laterally, the building structure of 1 is supported by the sturdy guide pillars of 2 extending from the foundation at the four corners of the building structure of 1. In addition, as the scale of the building increases, guide pillars are required inside and outside the building by calculation. It is desirable that the length of these two guide columns is slightly higher than the expected inundation depth. In addition, the guide pillars of 2 and the lower part of the building structure of 1 have a certain amount of tension, and as a connection that moves up and down like wheels, rollers, and gears, the upper part is more than the displacement amount of the building structure of 1 during an earthquake or windbreak. Clearance is required. In addition, the building structure of 1 needs to be made low-rise and lightweight in order to be levitated by the buoyancy of the buoyancy body of 7. When the building structure of 1 is a wooden structure or a steel frame, the building foundation is the upper part of the buoyant body of 7, and the foundation is not buried in the ground and has a slip stopper at the lower part as shown in drawings 3 and 4. Since it is on the foundation (fixed to the ground), the building standard law proves safety by structural calculation.

4 and 6 are cross-sectional views of the situation at the time of flooding. The line 10 shows the ground line in normal times, the line 9 shows the inundation height at the time of flooding, and the shaded portion 11 indicates the inundation part. The piping for building equipment such as water supply and drainage should be flexibly connected to the outside so that it will be in the same state as before the disaster when it returns to normal times.

In the method of inflowing the flooded water into the underground water tank of 6 to obtain the buoyancy of the buoyancy body of 7, it is clear that sludge accumulates in the underground water tank of 6 after the flood damage. The underground water tank needs to be deep. Since a plurality of 5 inflow pipes at the time of flooding are used to remove the accumulated sludge, a certain thickness is required, and one place needs to have a size of a passageway for cleaning and inspection. In addition, a mesh-like lid such as grating is required at the inflow inlet of 4 to prevent people from falling or large dust during floods from entering during normal times and clogging the inflow pipe during flooding of 5.

As a method of ascending the building according to the inundation, a shape in which a hydraulic jack or the like is installed on the foundation part of 3 as shown in FIGS. It is also possible to mechanically levitate a gear type using a pillar. In this case, the levitation device is costly, but the foundation work has the advantage of being inexpensive. The guide pillars of 2 and the building structure of 1 require a clearance that is greater than the amount of displacement during an earthquake or windbreak. In addition, the building structure of 1 needs to be made low-rise and lightweight in order to be mechanically levitated. When the building structure of 1 is made of wood or steel, the building foundation is not buried in the ground and has a slip stopper at the bottom as shown in drawings 5 and 6, but it is on the foundation of 3 (fixed to the ground). Since it will be in a state, the building standard law will prove safety by structural calculation.

Eliminating human damage and building damage due to flood damage is expected to lead to sustainable prosperity of the region and a decrease in building insurance premiums due to flood damage.

The foundation of 3 (fixed to the ground) is made of reinforced concrete and receives the load of the building so that the end of the foundation integrated with the building under the building structure of 1 is placed with a slip stopper. The building structure of 1 shall be made of wood or steel and designed to be as light as possible. By reducing the weight, the underground water tank of 6 and the buoyant body of 7 become smaller, and the construction cost is reduced. The guide pillar of No. 2 will be made of reinforced concrete and will be higher than the expected inundation height, and will be increased in order to increase the strength in areas where water flow is expected at the time of inundation. A track such as a guide rail is vertically attached to the building structure of 1 of the guide pillars of 2, and the building is smoothly moved up and down by a steel tire roller or the like having a tension installed at the bottom of the building. In addition, the building side of the guide pillar is concave so that the building does not come off the guide pillar even if the steel tire roller or the like deviates from the track. The lid of the inflow inlet at the time of flooding in 4 is made of steel grating, and the inflow pipe at the time of flooding in 5 is a PVC pipe of about 400φ, but one place is enlarged so that workers can put it in for cleaning and inspection.

The construction method of houses and other buildings that do not float and inundate by the buoyant bodies of FIGS. The guide pillar of No. 2 is constructed, and a track such as a guide rail is attached to the guide pillar of No. 2 in the vertical direction. As one of the production examples of the buoyancy body of 7, a steel bundle is arranged on the bottom surface of the underground water tank of 6 to make a temporary floor of water-resistant plywood, and styrene foam or styrofoam is layered on the floor to produce the buoyancy body of 7. A solid foundation made of reinforced concrete under the building structure of 1 is installed on the buoyant body. At this time, through bolts are installed at intervals of about 1.8 m from the water resistant plywood on the bottom surface of the buoyant body of 7 toward the solid foundation of the lower part of the building structure of 1, and the buoyant body of 7 is tied to the solid foundation. After the solid foundation at the bottom of the building structure of 1 is completed, a lightweight wooden or lightweight steel-framed building is constructed to complete the building structure of 1.

The construction method of houses and other buildings that are mechanically floated and not flooded in FIGS. 5 and 6 is as follows. Store in (fixed to the ground). After the foundation of 3 (fixed to the ground) is completed, the guide pillar of 2 is constructed and the track such as the guide rail is attached to the guide pillar of 2. When the guide columns at the four corners are completed, a solid reinforced concrete foundation under the building structure of 1 is installed on the foundation of 3 (fixed to the ground) so as to be separated from the foundation of 3. At this time, the upper part of the building lifting device such as the hydraulic jack of 8 is tied to the solid foundation of the reinforced concrete structure of the lower part of the building structure of 1. A lightweight building made of wood or a lightweight steel frame is constructed on the solid foundation at the bottom of the building structure of No. 1 to complete the building structure of No. 1.

If the number of guide pillars is increased, it will be possible to build a building with a large floor area if it is a low-rise building.
