JP 2007-239370 A
  Today, various rescue measures against flood damage such as tsunami, flood, and flooding have been proposed. Examples of the rescue means include installation of a lifeboat and evacuation to a designated hill. However, lifeboats are usually stored in a barn or the like at all times, so it is difficult to use them immediately in an emergency in the event of a disaster. The number of people on board and the amount of materials placed are limited. In addition, when evacuating to a designated hill, naturally, the victim must move to the designated evacuation site, which requires the awareness of the evacuation site on a daily basis, and the physical strength of the victim. There are concerns that victims may actually reach the evacuation site in case of emergency.
  The present invention has been made to solve the above problems, and can be used urgently after securing the number of people on board and the amount of loaded materials in the event of a disaster, forcing an unreasonable burden on the victim. The aim is to provide a wood deck as no rescue means.
The wood deck according to claim 1 according to one aspect of the present invention includes a floor plate portion constituting a top plate surface,
A structure that is connected to the floor plate portion and is interposed between an installation portion on which the wood deck is installed and the floor plate portion, and supports the floor plate portion;
A buoyancy body attached to a lower position of the floor plate portion in the structure,
The structure is
At least a pillar portion that is attached to the lower part of the four corners of the floor plate portion and supports the floor plate portion and is placed in an unfixed state on the installation portion;
A floor beam portion extending in parallel to the floor plate portion and disposed between the adjacent column portions to couple the both column portions;
A floor girder part that extends in parallel to the floor plate part and is disposed between the adjacent pillar parts in a direction perpendicular to the floor beam part, and couples the two pillar parts;
It is in a state parallel to one of the floor girder part or the floor beam part, and has a joist part coupled to the other of the floor girder part or the floor beam part in a state of supporting the lower part of the floor plate part. ,
The pillars arranged at the four corners are connected by the floor beam part and the floor girder part, and at the time of flooding, the floor board part, the structure body and the buoyancy body are caused by the buoyancy of the buoyancy body. It floats away from the installation part and can be used as a lifeboat or a fence.
  According to the present invention, the buoyancy body is attached to the lower position of the floor plate portion as the top plate, and the structure supporting the floor plate portion is not fixed to the installation portion, so that the wood deck overflows with water due to water damage. In such a case, the buoyancy body allows the wood deck to float on the water surface.
  In addition, the structural body is a floor beam in a state in which the pillars at the four corners that receive the load directly connected to the floor plate part, the floor beam part and the floor girder part that connect the pillar parts, and the lower part of the floor board part are supported. It is integrally formed as a structure by the joist part attached to the part. For this reason, even if the wood deck floats on the water from the installation part and leaves the installation part, the structure is not fixed to the installation part in the first place and is formed as an independent structure. Even without being supported by the portion, the shape of the structure itself can be maintained, and the floor plate portion can be supported in a floating state on the water.
  Furthermore, the floor plate portion is supported by each joist portion, and the floor plate portion can be supported while securing a long span between the column portions by using the floor beam portion and the floor girder portion for coupling the column portions. Therefore, the strength as a wood deck can be ensured without arranging many members below the floor plate portion. Conventionally, many bundles were placed in the lower part of the floor board part with a short span, and the bundle was fixed to the installation part to secure the strength as a wood deck, so it is not possible to secure a large space in the lower part of the floor board part. Although difficult, according to the present invention, the above-described configuration makes it possible to form a space necessary for disposing the buoyant body below the floor plate portion.
  The buoyancy body is a space surrounded by the pillar, floor beam, and floor girder on the four sides by the structure composed of the pillar, floor beam, floor girder, and joist. Therefore, when the wood deck floats on the water surface, it is possible to prevent the buoyant body from being detached from the inside of the structure by the beam portion.
  Thus, according to the present invention, because of the above structure, resistance and proof stress required when floating on the water surface due to water damage or the like can be added to the wood deck that is routinely adopted in the house, The wood deck can be used as a lifeboat or a fence.
  Moreover, according to the said structure, it is possible to support the large-area floor board part used for a wood deck from the lower part, and to give intensity | strength, and to use the said floor board part as a mounting base for person mounting. Since the wood deck can be used as a life-saving board or bag as described above, the disaster victim can save lives by moving to the wood deck that is always installed at home in the event of an emergency such as a flood.
  Thereby, according to the wood deck which concerns on this invention, it can use urgently, after ensuring the number of boarding persons and the amount of loading materials, and it can eliminate the forced movement burden with respect to a disaster victim.
  Moreover, invention of Claim 2 is the wood deck of Claim 1, Comprising: The said joist part is arrange | positioned in the position which becomes above the said buoyancy body.
  According to the present invention, the joist part is disposed above the buoyant body and supports the floor board part. Therefore, when the wood deck floats over the water, the upward buoyancy by the buoyant body causes the joist to press. Received by the department. Thereby, the pressing by the buoyant force of the buoyant body can be transmitted linearly or in a plane to the floor plate portion, and further to the beam portion. Thereby, since the floor board part and the structure can disperse and effectively receive the buoyant force generated by the buoyant body, it is possible to stabilize the state in which the wood deck floats on the water.
Moreover, invention of Claim 3 is the wood deck of Claim 2, Comprising: The said buoyancy body is arranged in multiple numbers in the direction orthogonal to the direction where the said joist part extends,
The joist part is disposed between the buoyant bodies arranged side by side and contacts both buoyant bodies, and the upper part of the joist part contacts the floor plate part at the same height as the uppermost part of the buoyant bodies. It is arranged in the state to do.
  According to the present invention, the joist part is disposed between the buoyant bodies arranged side by side so that the upper part of the joist part is in contact with the floor plate part at the same height as the uppermost parts of the two buoyant bodies. When the wood deck overflows with water and the upward pressure is generated by the buoyant body, the pressure by the buoyant body is distributed and transmitted to the joist part and the floor board part. At this time, since the joist part is attached to both the floor board part and the floor beam part, the floating force can be accurately transmitted to the floor board part as a force for pushing up the structure. Moreover, since the movement in a horizontal direction is controlled by the said joist part, the situation where a buoyancy body remove | deviates from a structure can be suppressed.
  According to a fourth aspect of the present invention, there is provided the wood deck according to any one of the first to third aspects, wherein the floor deck portion and the floor girder portion that are coupled orthogonally to the pillar portion. A fire beam is provided.

  Hereinafter, a wood deck according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a schematic configuration of a wood deck according to an embodiment of the present invention. FIG. 2 is a perspective view showing the wood deck 1. FIG. 3 is a perspective view showing the inside of the wood deck 1 as seen through. FIG. 4 is a perspective view showing the structure 3 to which the buoyancy body 5 is attached. In addition, in order to clarify the attachment structure of the buoyancy body 5 to the structure 3, only the outer frame of the floor board part 2 is shown with the dashed-two dotted line in FIG. 4, and detailed illustration is abbreviate | omitted.
  A wood deck 1 according to an embodiment of the present invention includes a floor board 2, a structure 3, and a buoyancy body 5. Further, the wood deck 1 includes a bench 6 on the floor board 2.
  The floor board 2 constitutes the top board surface of the wood deck 1. In the present embodiment, the floor board portion 2 is configured by arranging a plurality of long deck materials 22 in a certain direction. The floor plate portion 2 is attached to the upper portion of the structure 3 by attaching the plurality of deck materials 22 to a joist portion 33 and a floor girder portion 35 described later. The floor plate portion 2 is a member for placing a person on the upper surface 21. For this reason, the floor board part 2 has the intensity | strength which can be equal to a vertical direction in order to mount a plurality of people (for example, when loadable number of people is 6 people, about 360 kg load).
  The structure 3 is connected to the lower part of the floor board 2. The structure 3 is interposed between an installation surface (for example, the ground, which is an example of an installation unit in the claims) on which the wood deck 1 is installed and the floor board 2 to support the floor board 2.
  The structure 3 includes a column part 31, a floor beam part 32, a floor girder part 35, and a joist part 33.
  The column part 31 constitutes the four corners of the structure 3. The part of each pillar part 31 which comprises the structure 3 is arrange | positioned in the position used as the lower part of each corner part 25 (four corners) of the floor board part 2, and the said floor board part 2 is attached. The column part 31 receives the load and supports the floor board part 2, and is mounted in an unfixed state on an installation surface such as the ground. That is, the column part 31 is not attached (not fixed) to the installation surface, and is placed on the installation surface by the weight of the wood deck 1 itself. The placement load on the wood deck 1 is transmitted to the installation surface via the floor plate portion 2, the joist portion 33, the floor beam portion 32, and the column portion 31.
  The floor beam portion 32 is parallel to the floor plate portion 2, extends in a direction parallel to the length direction of the deck material 22, and is disposed between adjacent column portions 31 so as to correspond to the both column portions 31. Is connected to the end.
  The floor girder portion 35 is parallel to the floor plate portion 2, extends in a direction orthogonal to the length direction of the deck material 22, and extends between the adjacent column portions 31 in the direction orthogonal to the floor beam portion 32. The two pillar portions 31 are coupled to each other.
  The joist portion 33 extends parallel to the floor plate portion 2 and the floor girder portion 35, and both end portions in the length direction are attached to the floor beam portion 32. As shown in FIG. 1, the joists 33 are attached at regular intervals in the length direction of the floor beam portions 32, for example, between the floor beam portions 32 arranged in parallel and facing each other. The floor board portion 2 is attached to the upper portion of the joist portion 33 as a part of the structure 3.
  The buoyancy body 5 is attached to a position below the floor plate portion 2 in the structure 3. The buoyancy body 5 imparts buoyancy to the floor board 2 and the structure 3 coupled thereto. The buoyancy body 5 has a buoyancy that can float the floor board 2 and the structure 3 on which a plurality of persons are placed on the water as described above, for example. In the present embodiment, an example in which six buoyancy bodies 5 are attached to the structure 3 is shown.
  The bench 6 has a function as a chair that allows a person to sit on the upper surface of the bench 6. The bench 6 has its upper lid 61 opened by rotating in the direction indicated by the one-dot chain line in FIG. The inside of the main body 62 has a space as a storage space, and materials for evacuation (drinking water, life jackets, emergency food items, etc.) can be stored in the storage space.
  As described above, the column portion 31 is disposed below the four corner portions 25 in the floor plate portion 2 that forms a rectangular flat plate. The column portions 31 arranged in this way are all connected to the adjacent column portions 31 by the floor beam portion 32 and the floor girder portion 35, and the four column portions 31 are connected to the floor beam portion 32 and the floor girder portion 35. Are combined in the horizontal direction to form one frame (shaft assembly). Due to the combination of the column part 31, the floor beam part 32 and the floor girder part 35, the structure 3 has a resistance and proof strength in the horizontal direction and the vertical direction even when it is away from the installation surface. The structure 3 itself is self-supporting and has a strength structure.
  A fire beam 34 is bridged between a floor beam portion 32 and a floor girder portion 35 that are coupled orthogonally to the column portion 31. The fire beam 34 is interposed between the two orthogonal floor beam portions 32 to form a triangle with the floor beam portion 32 and the floor girder portion 35, and prevents the structure 3 from being twisted in the horizontal direction. The fire striking beam 34 may be directly attached to the floor beam portion 32 and the floor girder portion 35. However, in this embodiment, the floor beam portion 32 and the floor girder portion 35 are orthogonal to each other in the four column portions 31. Are attached to all the directly connected portions via a joining plate described later. Details of attachment of the fire beam 34 to the column 31, floor beam portion 32, and floor girder portion 35 will be described later.
  In the upper part of the structure 3 in which the column part 31, the floor beam part 32, the floor girder part 35, and the joist part 33 are assembled as described above, that is, on the upper face of the joist part 33 and further on the upper face of the floor girder part 35 When the deck material 22 is mounted side by side by nailing or the like, the floor board portion 2 is formed. The floor plate portion 2 is integrated with the joist portion 33 by this attachment, whereby the horizontal resistance is enhanced.
  The column part 31 transmits the load applied to the floor plate part 2 attached as described above to the installation surface via the joist part 33 and the floor beam part 32. That is, each bundle independently attached to the lower part of the floor surface does not receive the load of the floor plate part and transmits it to the installation surface as in the conventional case, but the floor beam part 32 to the column part 31 and By attaching the joist 33, the load on the floor plate 2 is dispersed and received by the entire structure 3.
  Moreover, since the structure 3 has the pillar part 31, the floor beam part 32, and the floor girder part 35, many bundles are not required in order to support a floor board conventionally. For this reason, it is possible to support the floor board portion 2 while securing a long span between the pillar portions 31, and the strength as the wood deck 1 can be obtained without arranging many members as the structure 3 below the floor board portion 2. It can be secured. In the past, many bundles were placed in the lower part of the floorboard part 2 with short spans, and the strength of the wood deck was secured by fixing the bundle to the installation surface, so a large space was secured in the lower part of the floorboard part 2 Although difficult, according to the wood deck 1 according to the present embodiment, a space necessary for disposition of the buoyancy body 5 can be formed below the floor plate portion 2.
  In this way, the buoyancy body 5 is disposed in the space formed below the floor plate portion 2. When the buoyancy body 5 is arranged in the structure 3 having the above-described configuration, the buoyancy body 5 is surrounded by the floor beam portion 32 and the floor girder portion 35. The floor beam portion 32 and the floor girder portion 35 can prevent the buoyant body 5 from coming out of the structure 3 when it overflows and floats on the water surface. Further, in such a situation, the buoyant body 5 is protected by the floor beam portion 32 and the floor girder portion 35 even when other floating matters existing on the water surface collide with the wood deck 1, that is, an obstacle. Therefore, the wood deck 1 is protected.
  In the present embodiment, it is preferable that at least the column part 31, the floor beam part 32, and the floor girder part 35 constituting the structure 3 are made of metal in order to ensure strength. In the present embodiment, an example in which the column part 31, the floor beam part 32, and the floor girder part 35 are made of metal and the joist part 33 is made of wood will be described.
  Next, the wood deck 1 provided with a handrail will be described. FIG. 5 is an exploded perspective view showing a schematic configuration of the wood deck 1 provided with a handrail. FIG. 6 is a perspective view showing the interior of the wood deck 1 with a handrail in perspective. FIG. 7 is a perspective view showing the structure 3 to which the buoyancy body 5 is attached in the wood deck 1 in a state where the handrail is provided. In addition, in order to clarify the attachment structure of the buoyancy body 5 to the structure 3, in FIG. 7, only the outer frame of the floor-plate part 2 is shown with the dashed-two dotted line, and detailed illustration is abbreviate | omitted.
  Although the wood deck 1 may have the above-described configuration, it is more preferable to have a handrail 9 as shown in FIGS. The handrail 9 is provided so as to cover the four sides of the floor board 2. For this reason, when the wooden deck 1 floats at the time of a flood, etc., it becomes possible to protect each person who got on the floor board part 2 from the obstacle colliding with the wooden deck 1.
  The configuration of the handrail 9 will be described. The handrail 9 includes a column part 31, a support member 7, and a support 71. In the wood deck 1 in which the handrail 9 is provided, each column part 31 of the structure 3 protrudes and extends upward from the mounting height position of the floor board part 2.
  The support member 7 extends in parallel to the four sides of the floor plate portion 2 and is disposed along the four sides so as to connect the adjacent column portions 31. Both ends of the support member 7 are coupled to the both column portions 31 protruding from the floor plate portion 2. Note that a plurality of support members 7 are provided with different height positions between the pillar portions 31. In the present embodiment, an example is shown in which three support members 7 are attached at different height positions.
  In addition, on one side portion forming the four sides of the floor plate portion 2, two support columns 71 are provided in a posture (a posture parallel to the column portion 31) that is spaced apart from each other and extends in the vertical direction. At the position where the column 71 is provided, the support member 7 is attached across the column 71 and the column part 31.
  The floor portion 2 is cut out along the shape of the pillar portion 31 so that the corner portion 25 corresponding to each pillar portion 31 does not hinder the protrusion of the pillar portion 31. The floor board part 2 is attached to the joist part 33 and the floor girder part 35 of the structure 3 while avoiding the arrangement positions of the pillar parts 31.
  In addition, the wood deck 1 having the handrail 9 is disposed at a position such as the entrance / exit 29 of an adjacent house at a portion between the two struts 71. Thereby, the movement from the adjacent house to the floor board part 2 of the wood deck 1 is enabled.
  When the handrail 9 is provided in this way, for example, when the wood deck 1 floats in the event of a flood, the person on the floor board 2 is protected from collision with an obstacle and is prevented from falling from the floor board 2. it can. Since the handrail 9 is set higher than the bench 6, it is possible to prevent a person sitting on the bench 6 installed on the floor board 2 from falling or colliding with an obstacle. Moreover, as shown in FIGS. 5-7, the other structure is the same structure as the wood deck 1 which does not have the handrail 9 demonstrated using FIGS. 1-4.
  Next, attachment of the buoyancy body 5 to the structure 3 will be described using the wood deck 1 having the handrail 9 as an example. FIG. 8 is a side view showing the structure 3 to which the buoyancy body 5 is attached. 9 is a side view from the other direction showing the structure 3 to which the buoyancy body 5 is attached, FIG. 10 is a bottom view showing the structure 3 to which the buoyancy body 5 is attached, and FIG. 11 is a view to which the buoyancy body 5 is attached. It is the perspective view which looked at the structure 3 from the downward direction. FIG. 12 is a perspective view showing a fixture attached to the floor beam portion 32 and an attachment pipe portion for attaching a buoyancy body. 8 to 12, in order to clearly show the attachment structure of the buoyant body 5 to the structure 3, the floor board portion 2 is seen through and indicated by a two-dot chain line.
  A fixture 8 for attaching the buoyancy body 5 is attached to the floor beam portion 32 constituting the structure 3. In this embodiment, the fixture 8 is made of metal, and is attached to the lower portion of each floor beam portion 32 so as to protrude downward. The fixture 8 is attached to the lower part of the floor beam portion 32 by bolting with bolts 85 and nuts 86. In the present embodiment, three fixtures 8 are provided on two floor beam portions 32 arranged in parallel at regular intervals in the length direction of the floor beam portion 32. The attachment 8 is provided with a ring-shaped portion 81 through which the attachment pipe 51 for attaching the buoyancy body 5 is inserted. The buoyancy body 5 is attached to the attachment pipe 51. In the present embodiment, an example in which two buoyancy bodies 5 are attached to one attachment pipe 51 is shown.
  The attachment pipe 51 extends in the same direction as the direction in which the joist portion 33 extends. In the present embodiment, three attachment pipes 51 are provided. Both ends of the attachment pipe 51 are attached to the attachment 8. The end portion in the length direction of the attachment pipe 51 is inserted in a state of being fitted to the ring-shaped portion 81 of the fixture 8, and the portion extending further beyond the ring-shaped portion 81 in the length direction is larger than the diameter of the ring-shaped portion 81. A detachment prevention cover 82 having a large diameter is attached by screwing.
  The buoyancy body 5 is made of foamed urethane, for example. In this embodiment, the buoyancy body 5 is cylindrical. The buoyancy body 5 may be covered with a protective sheet made of a resin such as vinyl chloride. The attachment pipe 51 is attached to the center of the circular cross section of the cylindrical buoyancy body 5 so as to penetrate the inside. In the present embodiment, two buoyancy bodies 5 are attached to one attachment pipe 51, and the structure 3 has six buoyancy bodies 5. Three buoyancy bodies 5 are arranged in the length direction of the floor beam portion 32 and two are arranged in the length direction of the floor girder portion 35. The number of buoyancy bodies 5 is not particularly limited, and the buoyancy to be obtained by all the buoyancy bodies 5 is determined according to the buoyancy required for the wood deck 1, and the number and size of the buoyancy bodies 5 are required. It is determined according to buoyancy.
  The buoyancy body 5 is preferably attached to the attachment pipe 51 so as to be freely rotatable. In this way, even when an obstacle collides with the buoyancy body 5 part when the wood deck 1 floats on the water during a flood, the impact of the collision is reduced by the buoyancy body 5 rotating around the attachment pipe 51. Is possible.
  The joist portion 33 extends parallel to the attachment pipe 51 and is disposed at a position above the two buoyancy bodies 5 that are attached to the attachment pipe 51 and lined up. As a result, the joist part 33 supports the floor plate part 2 above the buoyancy body 5, so that when the wood deck 1 floats during a flood, the joist part 33 receives the pressure due to the upward buoyancy by the buoyancy body 5. It is done. As a result, the joisting portion 33 can transmit the pressure due to the buoyant force of the buoyant body 5 to the floor plate portion 2 linearly or in a plane, and further to the floor beam portion 32. Thereby, since the floor board part 2 and the structure 3 can receive effectively the buoyancy by the buoyancy body 5, it is possible to stabilize the state in which the wood deck 1 floats on the water.
  Further, the joist 33 is parallel to the mounting pipe 51 as described above, and is arranged between the three buoyant bodies 5 arranged in the length direction of the floor beam 32 as shown in FIG. It is preferable that the joist 33 is provided on the upper part of the buoyant body 5 where the lower part of the part 33 comes into contact with both buoyant bodies 5. In this case, the joist portion 33 is disposed so that the upper portion of the joist portion 33 is in the same height as the uppermost portions of the buoyant bodies 5 and is in contact with the lower surface of the floor board portion 2. 8 to 11 show examples in which the configuration is adopted.
  According to this, the joist part 33 is disposed in a state where the upper part of the joist part 33 is in contact with the floor plate part 2 at the same height as the uppermost parts of the buoyant bodies 5 between the buoyancy bodies 5 arranged side by side. Therefore, when the wood deck 1 floats over the water, the buoyancy body 5 presses the floor plate portion 2 with the joist portion 33 sandwiched from both sides, and the pressing is performed via the joist portion 33 and the floor plate portion. 2 is transmitted directly. Thereby, it becomes possible to distribute and apply pressure as buoyancy by the plurality of buoyancy bodies 5 to each part of the floor plate portion 2, and the buoyancy body 5 can give stable buoyancy to the floor plate portion 2. Moreover, since the movement in the horizontal direction of the buoyancy body 5 is restricted by the joist part 33 and the floor girder part 35, a situation where the buoyancy body 5 is detached from the structure 3 is suppressed.
  The wood deck 1 is expected to receive a large impact due to a collision with a water flow or an obstacle in the event of a flood or tsunami. At this time, although the buoyancy body 5 is attached to the attachment pipe 51 as described above, if the buoyancy body 5 receives energy directed in the horizontal direction and the vertical direction due to the impact, the buoyancy body 5 is somewhat horizontal and vertical direction. It is thought that it will move to. However, with the arrangement of the joist portion 33, it is realized that the buoyancy body 5 gives a stable buoyancy to the floor board portion 2.
  FIG. 13 is a perspective view showing a connecting portion of the floor beam portion 32 and the floor girder portion 35 with respect to the column portion 31.
  As shown in FIG. 13, a floor beam portion 32 and a floor girder portion 35 that are connected to the pillar portion 31 at right angles to each other are joined to the pillar portion 31 by a joining plate 37. The joining plate 37 has a flat plate shape and is made of a metal such as iron, steel, or stainless steel. The shape of the joining plate 37 is a shape having three sides and forming a right triangle in plan view. Each side forming the joining plate 37 is formed as one side surface portion 372, the other side surface portion 373, and the fire striking beam 34, and these are integrally coupled. The one side surface portion 372 and the other side surface portion 373 are provided with screw holes.
  A corner portion forming a right angle of the joining plate 37 is formed by connecting one side surface portion 372 and the other side surface portion 373 at a right angle. The one side surface portion 372 and the other side surface portion 373 are formed by bending both ends in the width direction of a flat metal plate toward the inside of a triangle formed by the joining plate 37. In the corner portion of the joining plate 37, the bent portion is cut out in accordance with the shape of the column portion 31 (there is no bent portion).
  The outer side surface of the column portion 31 is applied to the inner side surface portion of the corner portion of the bonding plate 37, and the bonding plate 37 is welded to the outer surface of the column portion 31 in this state. Further, the floor beam portion 32 is assigned to one side surface portion 372 portion of the joining plate 37, and the floor girder portion 35 is assigned to the other side surface portion 373. In this state, the bolt 376 passed through the screw hole, The floor girder part 35 and the floor beam part 32 are fastened to the joining plate 37 by tightening nuts. Thereby, the floor girder part 35 and the floor beam part 32 are integrally attached to the column part 31. The structure 3 has a monocoque structure by the connection of the column portion 31 and the floor beam portion 32 via the joint plate 37.
  When the floor girder part 35 and the floor beam part 32 are attached to the pillar part 31 by the joining plate 37 as described above, the corner part of the structure 3 formed by the floor girder part 35 and the floor beam part 32 attached to the pillar part 31 is obtained. The presence of the fire beam 34 of the joining plate 37 suppresses the twisting in the horizontal direction.
  Moreover, since the joining plate 37 forms the above-described triangular shape in which the one side surface portion 372, the other side surface portion 373, and the fire beam 34 are integrated, the floor plate girder portion is formed on the column portion 31 using the joining plate 37. By attaching 35 and the floor beam part 32, in the said pillar part 31, the state in which the floor girder part 35 and the floor beam part 32 are attached to the pillar part 31 at right angles is maintained. Thereby, construction accuracy can be improved, and work efficiency when the floor girder part 35 and the floor beam part 32 are attached to the column part 31 at a right angle can be brought about.
  By this joining plate 37, the floor girder part 35 and the floor beam part 32 are integrated with the pillar part 31, so that the strength of the corner part formed by the two orthogonal floor beam parts 32 and the pillar part 31 is further increased. improves. As a result, the strength of the entire wood deck 1 can be ensured. In particular, the horizontal strength of the corner portion is enhanced.
  Further, in order to improve the appearance of the structure 3 on the outer surface side of the floor beam portion 32 and the floor girder portion 35, a decorative beam 320 may be further pasted. Furthermore, a height adjustment mechanism (adjuster) 310 may be provided under each column portion 31. The height adjusting mechanism 310 has an unillustrated adjustment bolt that connects the lower end portion of the column portion 31 and the installation surface, and this adjustment bolt has a thread groove and is screwed to the lower end portion and the installation surface of the column portion 31. doing. By rotating this adjustment bolt, the distance from the lower end of the column 31 to the installation surface is adjusted in accordance with the gap existing between the column 31 and the installation surface. As a result, it is possible to eliminate a situation in which each column portion 31 floats from the installation surface when the wood deck 1 is placed on the installation surface.
  In addition, the joist part 33 has a shape in which a part of the upper part of the end in the length direction is notched and does not interfere with the inwardly bent part of the floor beam part 32. A support portion 325 that supports the lower portion of the end portion in the length direction of the joist portion 33 is welded to the floor beam portion 32. The joist portion 33 is supported by the support portion 325 in a state where a portion below the end portion in the length direction and having no notch enters an internal region formed by a bent portion of the floor beam portion 32. And assembled to the floor beam portion 32. The joist portion 33 is fastened to the support portion 325 by bolting with a bolt 326, for example.

  The handrail 9 is attached along the edge 211 on the upper surface 21 of the floor board 2. The handrail 9 is set to an average height, for example, a height that is higher than the waist of a person of 165 cm, for example, in a state where a person rides on the upper surface 21. Moreover, the handrail 9 is not provided in a part of the edge 211, and a person can enter and exit the upper surface 21 from this part.
  The bench 6 is provided at the edge of the upper surface 21 along the handrail 9, for example. With this arrangement, a large space for placing a person on the upper surface 21 can be secured.
  As described above, the structure 3 constituting the lower part of the wood deck 1 is not fixed to the installation surface, and the wooden deck 1 is only placed on the installation surface. Stable and installed.
  As a result, by installing the wooden deck 1 in the yard of the house in the same manner as a conventional wooden deck (but not fixed to the installation surface), it can be used in the same way as a conventional wooden deck, In the case of flood damage such as flooding, the buoyancy body 5 can float on the water surface.
  For this reason, at the time of flooding, a disaster victim can escape from flooding only by moving on the wood deck 1 installed, for example in the garden at home. In addition, since the bench 6 is provided on the wood deck 1, by always storing emergency food and clothing in the bench 6, the wood deck 1 can be lifted in the event of a flood. Even if it is swept away from it, you can secure daily necessities.

A beam member 3015 is attached at a height position different from the upper beam portion 3011 so as to connect both adjacent column portions 31 between the column portions 31. The four beam members 3015 constitute a lower beam portion 3012.
  Further, a column 321 is attached between the upper beam portion 3011 and the lower beam portion 3012 so as to connect these two members. Thereby, the structural unit 301 is formed in a substantially cubic shape by the upper beam portion 3011, the lower beam portion 3012, and each column portion 31. In the structure 30, twisting in the horizontal direction is suppressed at two positions having different heights by the upper beam portion 3011 and the lower beam portion 3012.
Further, a plurality of joists 3013 are attached at equal intervals to the inside of the rectangular shape formed by the upper beam portion 3011 at an angle of 45 degrees with respect to the upper beam portion 3011. Since the joist 3013 is attached to the upper beam 3011 at an angle of 45 degrees, it also has a function as a fire beam . In addition, for the lower beam portion 3012, a fire beam 3014 is attached to each corner portion which is a rectangular inner side formed by the lower beam portion 3012.

That is, the column part 31 comprises the four corner parts of the structure 3, and each pillar part of four corners is provided by the floor beam part 32 or the floor girder part 35 spanned between each pillar part 31 similarly to 1st Embodiment. 31 is connected. Note that. The handrail 9 in the third embodiment has a support portion 91.
  FIG. 21 is a side sectional view showing attachment of the joist portion 33 to the floor girder portion 35. In the third embodiment, the joist portion 33 is substantially L-shaped in a side view from the length direction of the joist portion 33. The joist portion 33 is made of, for example, a metal such as iron, steel, or stainless steel, and includes a bottom surface portion 331 and a protruding piece portion 332. The bottom surface portion 331 is a long plate member having a surface parallel to the floor plate portion 2. The protruding piece portion 332 is a long plate member that extends from the edge of the bottom surface portion 331 to the floor plate portion 2 at right angles to the bottom surface portion 331. A plurality of joists 33 are spanned between one of the facing floor girders 35 or between the floor beam portions 32 (in the third embodiment, an example in which the joist 33 is spanned between the floor girders 35 is shown). The joists 33 are provided as many as the buoyancy bodies 5 arranged in parallel in the longitudinal direction of the floor girder 35.
  The floor girder portion 35 is made of a metal such as iron, steel, stainless steel or the like that is substantially C-shaped in a side view from the longitudinal direction (in FIG. 20, for the sake of clarity, the floor girder portion 35 is not particularly substantially C-shaped). The joist portion 33 is joined to the inner bottom portion 351 by welding or bolting in a state where both end portions of the bottom surface portion 331 are placed on the inner bottom portion 351 of the floor girder portion 35. Further, the bottom edge portion 331 of the joist portion 33 and the side edge portion 333 in the length direction of the protruding piece portion 332 may be joined to the inner wall of the side surface 352 of the floor girder portion 35.
  As shown in FIG. 20, in the third embodiment, the aggregate 50 is configured by connecting a plurality of buoyancy bodies 5 in both the longitudinal direction and the width direction of the joist section 33. The aggregate 50 has a shape in which the column portion 31 is fitted into the inside of a frame formed by connecting the floor girder portion 35 and the floor beam portion 32.
  In addition, the joist part 33 is provided in the number that at least the buoyancy bodies 5 constituting the assembly 50 are continuous in the longitudinal direction of the floor girder part 35. Each joist portion 33 is arranged at a position where the protruding piece portion 332 becomes an edge portion of the buoyant body 5 in the longitudinal direction of the floor girder portion 35. Each buoyancy body 5 is arranged in two in the direction in which the joist part 33 extends, the lower part of the edge part is placed on the bottom surface part 331 of the joist part 33, and the protruding piece part 332 is provided on the side surface part of each buoyancy body 5. Thus, each buoyancy body 5 is attached to the joist portion 33 with the edge portion positioned by the protruding piece portion 332. Thereby, the buoyancy body 5 which comprises the aggregate | assembly 50 is stored in the said frame and attached. Further, the joist portion 33 is attached to the inner side surface of the floor beam portion 32 shown on the near side (right side) in FIG. 20 so that the bottom surface portion 331 protrudes in the direction opposite to the side surface of the floor beam portion 32. Is preferred. Thereby, the buoyancy body 5 arranged at the end can be reliably attached to the floor beam portion 32.
  FIG. 22 is a perspective view showing an example of the buoyancy body 5 in the wood deck 1 according to the third embodiment. The buoyancy body 5 used in the wood deck 1 according to the third embodiment includes, for example, a casing (for example, a polytank) 501 having a space inside, and the inside of the casing 501 is filled with urethane foam. . Each buoyancy body 5 is formed with a concave notch 512 extending in the length direction of the joist 33 on a side surface 511 facing the adjacent buoyancy body 5.
  FIG. 23 is an exploded perspective view showing another example of the buoyancy body 5 in the wood deck 1 according to the third embodiment. The buoyancy body 5 may be configured as follows. Another example of the buoyancy body 5 includes a cover member 502, a main body 503, and a bottom plate 504. The cover member 502 is made of, for example, a metal plate such as a fluororesin steel plate. The main body 503 is formed in a rectangular parallelepiped cylindrical shape using, for example, wood or synthetic resin. The main body 503 is filled with foamed urethane 505. The bottom plate 504 is a metal flat plate, for example, a fluororesin steel plate. A bottom plate 504 is attached to the lower portion of the main body portion 503 filled with urethane foam. The cover member 502 and the bottom plate 504 are attached to the main body portion 503 by bolting or bonding, and the buoyancy body 5 is completed.
  The buoyancy body 5 may be a cube formed of wood, synthetic resin, metal or the like. The buoyancy body 5 is filled with a substance such as foam having closed cells such as urethane foam and polystyrene, and the buoyancy is ensured so that the water surface can float in the event of a flood.
  Further, (1) the casing 501 or (2) the cover member 502, the main body portion 503 and the bottom plate 504 of the buoyancy body 5 are formed of a highly rigid metal, and the width between the both facing floor girder portions 35 is increased. 20 by inserting the end portion in the width direction into the C-shaped inside of the spar 35 shown in FIG. 21 and fixing it to the spar 35 with the same length as the joist 33 shown in FIG. The buoyancy body 5 attached to the structure 3 can function as the joist 33. In this case, the attachment of the joists 33 can be omitted from the structure 3.
  FIG. 24 is a side cross-sectional view of the coupling portion showing the coupling state of the buoyancy bodies 5 forming the assembly 50. As described above, each buoyancy body 5 is formed with a concave notch 512 extending in the length direction of the joist 33 on the side surface 511 facing the adjacent buoyancy body 5. As shown in FIG. 17, the notch portion 512 is formed in each side surface portion 511 of two buoyancy bodies 5 arranged adjacent to each other. For this reason, when the two buoyant bodies 5 are adjacent to each other and the side surface portions 511 are brought into close contact with each other, one gap 513 is formed by the combination of both the notch portions 512.
  An insertion member 515 is inserted in the gap 513 in the longitudinal direction of the joist 33, that is, in the depth direction of the paper in FIG. By inserting the insertion member 515 into the gap 513, the adjacent buoyancy bodies 5 are coupled to each other by abruptly. Accordingly, each buoyant body 5 is positioned relative to the adjacent buoyant body 5 and the movement in the vertical direction is restricted, so that each flat plate member can be attached to the frame at an appropriate position and posture. In addition, the connection method of the buoyancy bodies 5 is not limited to the above, and various other methods can be used.
  Next, the support structure 10 will be described with reference to FIG. 25 in addition to FIG. FIG. 25 is a perspective view showing an elevated deck.
  The support structure 10 includes a column part 101, a second girder part 102, and a second beam part 103. The column portion 101 is connected to the lower portion of each column portion 31 of the structure 9 and supports the lower portion of the column portion 31. The support structure 10 is fixed to the ground in a state of being interposed between the structure 3 and the ground on which the wood deck 1 is installed. That is, the lower portion of the structure 3 is supported by the support structure 10.
  The second beam portion 102 and the second beam portion 103 are spanned between the column portions 101 to join the upper portions of the column portions 101 to each other. By this connection, a frame body 105 is formed by the support column part 101, the second beam part 102, and the second beam part 103. Since the frame body 105 is formed in the upper part of the support column 101, a space S is formed below the frame body 105. For this reason, the said space S is utilized as a parking space etc. which park the car M, for example.
  Note that a flat plate member 107 made of, for example, polycarbonate is attached to the second beam portion 103. The flat plate member 107 functions as a bag when the lower side of the structure 3 is used as a parking space, for example, and a stilt deck 100 such as the structure 3 and the support structure 10 shown in FIG. When it is installed adjacent to the second floor part, etc., it functions as a second floor veranda or corridor.
  FIG. 26 is a side cross-sectional view showing a coupling portion between each column portion 31 of the structure 3 and each column portion 101 of the support structure 10.
  An engaging portion 315 that engages with an upper portion of each column portion 101 of the support structure 10 is provided below each column portion 31 of the structure 3. On the other hand, a protruding portion 12 that engages with the engaging portion 315 is provided at the upper end portion of each column portion 101.
  The engagement portion 315 of the column portion 31 is formed with a gap cut out in a direction from the lower surface of the column portion 31 toward the floor plate portion 2 (upward). The width dimension of the inner shape of the gap is set to be slightly larger than the outer dimension of the protruding portion 12. In addition, the said space | gap is created, for example by forming the pillar part 31 by bending metals, such as an iron plate. That is, in this embodiment, the inside of the lower end part of the column part 31 having a cavity is the engaging part 315.
  Further, the projecting portion 12 provided on the upper surface of the support column 101 extends from the upper surface of the support column 101 toward the structure 9 in the length direction of the support column 101. The width dimension of the protruding part 12 is set slightly smaller than the width dimension surrounded by the inner surface of the gap as the engaging part 315 of the column part 31. Therefore, the protruding portion 12 can be inserted into the gap as the engaging portion 315, and after insertion, the protruding portion 12 is loosely fitted into the gap.
  For this reason, the structure 3 is placed on the support structure 10 so that the engaging portions 315 below all the column portions 31 are fitted into the protrusions 12 existing at the upper ends of the column portions 101 at the corresponding positions. Thus, both are engaged by loose fitting of the protruding portion 12 with respect to the engaging portion 315, and the structure 3 is placed and mounted on the support structure 10 in a state where movement in the horizontal direction is restricted. In addition, the outer diameter width dimension of the column part 31 and the outer diameter width dimension of the support | pillar part 101 are made the same. With this placement, the structure 3 is placed on the ground via the support structure 10.
  However, since the projecting portion 12 is loosely fitted to the engaging portion 315, when a pressing force is applied to the structure 3 in the upward direction, the structure 3 can move in the upward direction. . For this reason, when the water level rises to the installation height of the structure 3 due to a flood or a tsunami, the structure 3 is supported upward in accordance with the buoyancy when the water is pressed upward by buoyancy. It can move away from 10 and float on water. Moreover, since the aggregate 50 is attached to the structure 3, the structure 3 floats on the water, and the structure 3 can function as a lifeboat or a fence.
  Next, a method for manufacturing the stilt deck 100 will be described. First, four support columns 101 are fixedly installed at, for example, four corners of a rectangular area used as a parking space. Subsequently, the second girder portion 102 is attached to the upper portion of the support column 101 between the support columns 101 having a relatively longer interval, and the support column portions 101 are disposed between the support columns 101 having a relatively shorter interval. A second beam portion 103 is attached to the upper portion of 101. Thereby, the frame body 105 is formed at the upper position of the support column 101. In addition, it is preferable that the frame body 105 is formed so that the upper end part of the support | pillar part 101 and the protrusion part 12 may protrude above the said frame assembly. Next, the flat plate member 107 is attached to the outer portions of both the second beam portions 103. Thereby, the support structure 10 is created.
  Subsequently, in the structure 3 having the floor girder 35, the floor beam 32, and the handrail 9, the floor girder is located at a position corresponding to the edge of each buoyant body 5 of the assembly 50 attached to the structure 3. A plurality of joists 33 are attached to the floor girder 35 so as to extend between the portions 35.
  Then, the buoyancy body 5 of the assembly 50 is attached to the support structure 10. In a state where two buoyancy bodies 5 are arranged in the length direction of the joist section 33, the side surface in the longitudinal direction of the floor girder section 35 is brought into contact with the inner surface of one floor beam section 32, and the other side The edge portion is placed on the bottom surface portion 331 of the joist portion 33. At this time, the protruding piece portion 332 of the joist portion 33 abuts on the side surface portion 511 of the mounted buoyancy body 5, and thus in the width direction of the joist portion 33 of the buoyancy body 5 (longitudinal direction of the floor girder portion 35). In other words, the buoyancy body 5 is positioned in the width direction by the protruding piece portion 332. This operation is performed by the number of buoyancy bodies 5 arranged in the longitudinal direction of the floor girder part 35.
  At this time, a further buoyancy body 5 is attached adjacent to the already attached buoyancy body 5 in the width direction of the joist section 33. At this time, the buoyancy body 5 that has been attached is inserted into the notch 512. 515 is fitted.
  And the side part 511 of the buoyancy body 5 attached next is made to contact | abut to the side part 511 of the buoyancy body 5 which the said fitting member 515 is inserted and adjoins. The fitting member 515 attached to the buoyancy body 5 adjacent in the width direction of the joist portion 33 is fitted into the cutout portion 512 of the side surface portion 511 of the buoyancy body 5. For this reason, since each buoyant body 5 is positioned with respect to the adjacent buoyant body 5 and the movement in the vertical direction is restricted due to the necessity, each flat member is attached to the frame at an appropriate position and posture. Take possible.
  By attaching the buoyancy body 5 as many times as necessary to the frame body 105, the assembly 50 is accommodated in the frame pair 105 and attached. Each attached buoyancy body 5 is attached to the joist portion 33, the floor beam portion 32, and the floor girder portion 35 in a coupled manner. The floor board portion 2 is fixed and attached to the floor beam portion 32 and the floor girder portion 35 above the assembly 50 attached in this manner.
  Next, the structure 9 is placed on the support structure 10 so that the engaging portions 315 at the bottom of each column portion 31 are fitted into the protruding portions 12 at the upper ends of the column portions 101 at the corresponding positions. Thereby, the structure 3 is attached to the support structure 10 in a state in which the structure 3 can be detached from the support structure 10 in the upward direction, and the raised deck 100 shown in FIG. 26 is created.
  Note that either the attachment of the assembly 50 to the structure 3 or the attachment of the structure 3 to the support structure 10 may be performed first.
  Next, another example of the assembly 50 will be described. FIG. 27A is a perspective view showing another example of the aggregate 50, and FIG. 27B is a side view showing another example of the aggregate 50. FIG.
  The aggregate 50 may have a shape that is inclined in the longitudinal direction of the joist 33 when attached to the structure 9 as shown in FIG. Good. That is, each buoyancy body 5 is formed so that the thickness gradually decreases in the direction. Note that the aggregate 50 may be inclined in the longitudinal direction of the floor beam portion 32. That is, each buoyancy body 5 is formed so that the thickness gradually decreases in the direction.
  According to this, water that accumulates on the buoyant body 5 of the aggregate 50 can be guided to a lower side in the inclined direction during rainy weather or flooding, so that drainage can be smoothly performed from the upper surface of the aggregate 50.
  According to the stilt deck 100 created in this way, the space S formed below can be used as a parking space or the like, so even in a small house where the area for installing the wood deck cannot be secured in the site. It can be installed above the parking space.
  In addition, by providing a doorway on the second floor of the house and allowing people to enter and exit from the doorway on the floor plate part 2, it has a function as a life-saving device in the event of a disaster, while providing additional space as a residence. It is possible to create. In addition, when it is impossible to communicate with the entrance / exit at the second floor part of the house, as shown in FIG. 28, a stairway (or ladder) 80 that can be raised from the installation surface onto the floor board 2 may be provided. .
  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. For example, although the embodiment of the present invention is referred to as a wood deck 1 above, the wood deck according to the present invention may be made of wood in addition to the metal shown above, and further, synthetic resin. It may be made of a material such as wood and resin plywood.
