Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevated metal building suitable for use as an evacuation building for tsunami flood countermeasures.

[0002]

2. Description of the Related Art In recent years, there have been many earthquakes all over the world.
When an earthquake occurs, not only will it cause damage such as the collapse of houses, but the coast will also cause significant physical and human damage due to the tsunami. In Japan, the disaster caused by the tsunami on Okushiri Island in Hokkaido is still fresh in our memory.

As seen in the tsunami disaster on Okushiri Island, it is not uncommon for tsunamis to rush immediately after an earthquake. The height of the tsunami is several meters. As a result, there are not a few people who were delayed in evacuation and were caught in the tsunami.

In order to prevent human damage caused by the tsunami, it is most effective to construct a high and strong evacuation building on the coast.
However, there is no refuge for tsunami in Japan. Only high schools are designated as evacuation centers. It is clear from the case of Okushiri Island that evacuation centers away from the coast do not function effectively in the actual tsunami.

[0005]

[Problems to be Solved by the Invention] Japan is an earthquake-prone country and is surrounded on all sides by the sea. Therefore, all coastlines are at risk of tsunami. In preparation for the upcoming earthquake, it seems that measures have been taken for prediction and measures against collapse of houses and fire, but effective measures against the tsunami have not been taken.

[0006] An effective countermeasure against a tsunami is considered to be the construction of the evacuation building dedicated to the above-mentioned tsunami countermeasures, but the construction has not been considered at all. This has to be said as neglect of human life. The biggest reason why we cannot proceed with the construction of an evacuation building dedicated to tsunami countermeasures is that the construction of a high and strong building that can withstand the tsunami requires enormous cost.

The present invention was devised in view of such circumstances, and it is a high and strong structure that can endure a tsunami, but the construction cost is low, and it is extremely suitable as an evacuation building for tsunami and flood countermeasures. The purpose is to provide an elevated metal structure.

[0008]

[MEANS FOR SOLVING THE PROBLEMS] An elevated metal structure according to the present invention comprises a base portion formed into a pier shape by driving a metal pillar material into the ground, and a metal on the pier-shaped base portion. It is characterized by comprising a high-floor indoor part constituted by panels.

This elevated metal building is light in weight due to the combination of the metal pillar and the metal panel, the material cost is low, and the construction can be done by driving and welding the metal piles. Therefore, the construction period is short. Therefore, the construction cost is low. It is strong because it is based on multiple metal piles driven into the ground. Since the tsunami flood passes through the metal legs that are long in one direction and under the indoor space, there is almost no resistance from the tsunami flood. Therefore, a large number of buildings can be built on the coast and riverbanks as an evacuation building for tsunami flood countermeasures.

As the metal panel, a face beam panel in which a plurality of corrugated plates formed of a lath net are superposed and coupled so that the directions of the waves intersect each other is desirable from the viewpoint of weight reduction and cost reduction.

It is desirable to dispose a reinforcing pipe in the groove of the corrugated plate forming the face beam panel.

The reinforcing pipe can be used as a wiring space and a piping space.

The base portion includes, for example, a plurality of metal piles driven into the ground, a plurality of metal legs that are respectively connected to the plurality of metal piles and project to the ground, and the upper ends of the plurality of metal legs. It can be constituted by a plurality of metal beams which are connected to each other and are combined in a frame shape.

It is desirable that a plurality of metal piles driven into the ground be connected and reinforced in the ground by a plurality of connecting members that connect the upper ends and are combined in a frame shape. Since the connecting member is underground, it does not receive resistance due to the tsunami collision.

When used as an evacuation building for tsunami flood countermeasures, it is desirable to orient the longitudinal direction of the elevated metal structure in the direction of the water flow in the tsunami flood in order to reduce the resistance of the water flow.

Except when it is used as an evacuation building, the indoor part can be used as a public facility such as a meeting place or a public hall.

B
-B line arrow view, FIG. 5 is a CC line arrow view of FIG. 4, and FIG. 6 is a structure explanatory view of the metal panel which comprises an indoor part. Further, FIG. 7 is a perspective view showing another metal panel, and FIG. 8 is a vertical sectional front view showing another example of the elevated metal building.

This building is constructed on the coast as an evacuation building for tsunami countermeasures. As shown in FIGS. 1 and 2, this building has a rectangular planar shape and is oriented so that its longitudinal direction is perpendicular to the shoreline. The structure is composed of a base portion 10 and a high-floor indoor portion 20 constructed on the base portion 10. As for scale,
Here, the standard width is 4.4 m and vertical length is about 53 m. Further, the height of the base portion 10 is 3 m, 5 m, and 7 m as standard depending on the expected height of the tsunami, and can be 10 m.

The base portion 10 includes a plurality of metal piles 11 that are driven into the ground, a plurality of metal legs 12 that are connected above the plurality of metal piles 11 and project to the ground, and a plurality of metal pieces. A plurality of metal beams 13 hung between the upper ends of the legs 12
And

The outer diameter of the plurality of metal piles 11 is 100 mm.
The round bars are made of steel and are arranged in the plane including the four sides of the rectangle at predetermined intervals in the vertical and horizontal directions. The metal piles 11 lined up in the vertical direction and the horizontal direction are connected by the angles 14, 14 that sandwich the upper end from both sides.

As shown in FIGS. 3 and 5, the angles 14 and 14 are connected to the upper end of the metal pile 11 by welding the metal pile 11 and digging the ground along each side of the rectangle. Later, it is backfilled to be installed underground. The angles 14 and 14 form a plurality of corner frames, so that the metal piles 11 aligned in the vertical and horizontal directions are formed.
Will be reinforced.

The plurality of metal legs 12 are made of steel square tubes, and their cross-sectional dimensions are set so that the metal piles 11 can be inserted therein. Then, by inserting the upper end portion of the metal pile 11 into the lower end portion of the metal leg 12 and welding, the metal leg 12 is connected onto the metal pile 11. At this time,
The angles 14 and 14 also serve as receiving members for the metal legs 12.

The plurality of metal beams 13 have a structure in which a pair of upper and lower channel members 13a, 13 are connected by diagonal members 13b. As shown in FIGS. 2 to 4, each metal beam 13 has both ends welded to the upper end side surfaces of two adjacent metal legs 12 and 12, and a plurality of corner frames similar to the angles 14 and 14. By configuring the above, the metal legs 12 arranged in the vertical direction and the horizontal direction are reinforced.

Indoor part 2 constructed on the base part 10
0 is a face beam panel 2 for all parts including roof, floor and wall
1. The face beam panel 21 is shown in FIG.
As shown in (B), the two front panels 22, 22
Two corrugated plates 23, 23 are sandwiched between the two corrugated plates 2
The intermediate panel 24 is sandwiched between 3 and 23 and integrated.

Here, the two corrugated plates 23, 23 are the same as in FIG.
The lath net as shown in FIG. 7A is formed into a corrugated shape, and is superposed with the directions of the waves intersecting at right angles. The lath net is manufactured by stretching a steel plate having a large number of slits, for example, a few mm in a direction perpendicular to the slits. Then, the two corrugated plates 23, 23 are joined by spot welding the portions where the waves intersect with each other while sandwiching the intermediate panel 24. Similarly,
The two corrugated sheets 2 and 22 are also spot-welded at the contact portions with the two corrugated sheets 23 and 23, so that
It is connected to 3,23.

Such a face beam panel 21 has high strength and is lightweight. By using this for all the parts including the roof, floor and walls, the indoor part 20 is extremely lightweight. Further, since the roof, floor, walls, etc. are constructed by welding, the construction period is very short.

As the surface beam panel 21, it is also possible to use a corrugated plate 23 in which a steel pipe 25 is inserted, as shown in FIG. The pipe 25 not only contributes to the improvement of the strength of the face beam panel 21, but also the inside thereof can be used as a laying space for electric wiring, piping and the like. It is also possible to use it as a connecting member by protruding the tip of the pipe 25 and inserting it into an adjacent panel.

Reference numeral 30 is a wire for reinforcement.
Further, the indoor portion 20 is connected to the ground by a staircase (not shown).

The tsunami countermeasure evacuation building as described above has the following features. Since it is made of steel and the number of parts is small, the material cost is low. Since it is assembled by driving the metal pile 11 and welding the metal leg 12, the metal beam 13, and the face beam panel 21, the construction period is short. Therefore, the construction cost is easy and a large amount can be constructed in coastal towns and villages.

By constructing a large quantity in coastal towns and villages, residents can immediately evacuate to this evacuation building when an earthquake occurs.

Since the tsunami passes through the portions of the metal legs 12 under the floor based on the metal piles 11 deeply driven into the ground, the tsunami does not collapse and is safe. The fact that the angles 14, 14, which are the connecting members, are buried in the ground also contributes to this safety. It goes without saying that it exhibits excellent resistance to earthquakes and fires.

Except when it is used for evacuation, it can be widely used in public halls, meeting places, etc.

As measures against earthquakes, measures against tsunami are prediction of earthquakes,
This is far behind the measures for collapse of houses.
The damage caused by the tsunami can be even greater than the direct damage caused by the earthquake. This structure is dedicated to countering this delayed tsunami.

Although the above example is an evacuation building for tsunami countermeasures, this structure can be constructed on the riverbank as an evacuation building for flood countermeasures. This structure, which has high strength, low construction cost, and is nonflammable, can be widely used as various evacuation buildings.

Further, as shown in FIG. 8, the metal beam 13 can be omitted, and the habitation portion 20 can be formed directly on the metal leg 12 by the surface beam panel 21. In other words, the surface beam panel 21 that constitutes the floor material is a metal beam. Reference numeral 15 is a diagonal member that supports the face beam panel 21 as a floor material. Furthermore,
As seen in this example, the metal pile 11 can also serve as a metal pillar.

[0036]

As described above, the elevated metal building according to the present invention is an elevated type that is not damaged by the tsunami flood, and the construction cost is low. , Can be built in large quantities on the banks of the river, which makes a great contribution to protecting lives from tsunami floods.

Japan is an earthquake-prone country and is surrounded on all sides by the sea. Therefore, all coastlines are at risk of tsunami. Nevertheless, until now there have been no effective countermeasures against tsunami. By building many elevated metal structures in coastal towns and villages in preparation for the coming tsunami, the human disaster caused by the tsunami can be significantly reduced. It goes without saying that the effect is great.
