JP 2002-256634 A

Various types of prefabricated temporary housing have been proposed that can be built in a matter of days in response to an emergency, but in order to build the necessary number of houses in the event of a large-scale disaster, materials are manufactured. The system is inadequate. In addition, it is difficult to ensure that the production volume is secured and stocked for walls, floor panels, and building units that have been made into parts so that they can always respond to disasters that do not know when they occur and are easy to perform on-site. is there. It is necessary to consider improvement in terms of cost.
In developing countries, there are many countries that have poor living conditions and large-scale housing demand, and in order to solve these housing problems, buildings with structures that can be supplied in large quantities at low construction costs are desired. ing.

  FRP sandwich panels are excellent building materials in terms of weight reduction and durability, and are used in various applications. However, the examples of use and proposals are limited to use in a part of a building. It has been.

An object of the present invention is to provide an FRP sandwich panel method building that can be constructed with easy construction, a short construction period, and low cost, can easily produce main components locally, and can be supplied in large quantities, and a construction method thereof. It is.
Another object of the present invention is that it can be used in the FRP sandwich panel method building of the present invention, can be manufactured manually, and does not require the use of heavy machinery during transportation and installation. Is to provide an FRP sandwich panel that can be easily constructed and a method for the same.

The FRP sandwich panel method building of the present invention is a building using an FRP sandwich panel in which a core material made of a heat insulating material is covered with a surface layer of glass fiber reinforced plastic, and has a cross-sectional shape of L shape, flat shape, and groove shape. The FRP sandwich panel having any one of the above shapes is combined to form an outer wall, a floor, and a roof.
That is, it is set as the panel construction building which made the outer wall, the floor, and the roof all panel structures, and uses an FRP sandwich panel for the panel. As the heat insulating material used as the core material, various foamed resins and the like are used. However, as long as it has heat insulating properties and can constitute an FRP sandwich panel having strength used as an outer wall, a floor, or a roof of a building, it is particularly limited. Not.

According to this configuration, the FRP sandwich panel in which the core material and the surface layer are integrated serves as the building structure and the interior and exterior. Since the outer wall, floor, and roof are all configured by the FRP sandwich panel that also serves as the structure and the interior and exterior, a building can be constructed simply by connecting and assembling the FRP sandwich panel. By using foamed resin or the like as the core material, the FRP sandwich panel can be a panel having strength and heat insulation necessary for the building structure, and can be a lightweight panel. Therefore, what has a required size and a required strength can be stored in a weight that can be transported manually. In addition, the heat insulating material can be produced by cutting it into a predetermined length at the manufacturing site, or by applying a surface layer of glass fiber reinforced plastic to the core material prepared as the predetermined length by manual application or the like. Therefore, no special manufacturing machine is required.
In the FRP sandwich panel, the cross-sectional shape is any one of L shape, flat shape, and groove shape, and any combination of the outer wall, the floor, and the roof can be configured by the combination. Less is enough. In addition, a free floor plan can be realized by combining the L-shaped, flat-shaped, and groove-shaped FRP sandwich panels.

In this way, all the outer walls, floors, and roofs can be configured with the FRP sandwich panel, the number of types of building materials can be reduced, the joint structure of each part can be unified, and each FRP sandwich panel can be made lightweight. No special assembly equipment or special construction techniques are required, and anyone can easily build and have excellent workability. Since an FRP sandwich panel is used, it is possible to omit coating as an exterior or pasting of a cloth as an interior. The FRP sandwich panel itself can be easily manufactured even at construction sites by preparing the core material and the FRP material for coating without requiring a special manufacturing machine. There is no need to prepare a finished product. From these, according to this FRP sandwich panel construction, large-scale supply in a short period becomes possible when a large-scale natural disaster occurs.
In addition, temporary housing in Japan and housing that requires a large amount of supply in developing countries have a common level of requirements, so by sharing them, domestic and developing countries can supply each other as needed. I can meet each other.
In this way, it can be constructed with low cost, a short construction period, and easy construction, and the production of the main members can be easily performed locally, and a large amount can be supplied in a short period of time.
Moreover, since the FRP sandwich panel using the core material which consists of a heat insulating material is excellent also in heat insulation, the weather resistance of a surface layer, and the designability, it leads also to the improvement of the living environment corresponding to cost.

In the FRP sandwich panel construction building of this invention, the type of the cross-sectional shape of the FRP sandwich panel in one building is 6 types or less, preferably 4 types or less, for example, 3 types. You may use for several places among an outer wall, a floor, and a roof. The types mentioned here are different types even if they are similar, if the dimensions are different.
In this way, the number of types of FRP sandwich panels can be reduced by using the same type of FRP sandwich panels at a plurality of locations on the outer wall, floor, and roof. By reducing the number of types of FRP sandwich panels to 6 or less, it is possible to realize simple construction by improving the production efficiency of FRP sandwich panels and unifying the joining work by unifying the shapes.
If each type of FRP sandwich panel has the same width or a multiple of the reference width, the production efficiency can be further improved.
About the length of a FRP sandwich panel, it is preferable to unify to one type or two types for each cross-sectional shape, but the number of types may be increased. This is because, when an FRP sandwich panel is produced, a long heat insulating material is prepared, cut into a required length, and then coated with glass fiber reinforced plastic.

In the FRP sandwich panel method building according to the present invention, it is preferable to use an L-shaped FRP sandwich panel at the four corners of the outer wall so that the protruding corners face outward.
Since the L-shaped FRP sandwich panel has a high bending rigidity, the rigidity of the entire building can be enhanced without using any additional members by using it at the four corners of the outer wall. In addition, since the L-shaped FRP sandwich panel can stand on its own, it can be used to assemble other FRP sandwich panels by installing the L-shaped FRP sandwich panel at the four corners before assembling the building. Workability is also improved.

When L-shaped FRP sandwich panels are used at the four corners of the outer wall in this way, the panel disposed next to one side of the L-shaped FRP sandwich panel disposed at each corner is designated as an L-shaped FRP sandwich panel. A groove-shaped core part may be constituted by two matching FRP sandwich panels. In this case, one side of the L-shaped FRP sandwich panel arranged adjacently protrudes indoors as a sleeve wall.
In this way, by forming a groove-shaped core with two FRP sandwich panels, the rigidity of the building is further improved. The indoor space in each core is a relatively small space, but it can be used as an installation core or a storage room for water facilities such as toilets, bathrooms, and kitchens. Efficiency can be improved.

In the FRP sandwich panel construction building of the present invention, the floor is composed of a groove-shaped FRP sandwich panel facing upward, and a flat FRP sandwich panel placed on the array of the groove-shaped FRP sandwich panels, It is good also as what put earth and sand used as a weight in the groove-shaped FRP sandwich panel which comprises a floor.
By putting earth and sand in the groove-shaped FRP sandwich panel constituting the floor in this way, the building can be stabilized and durability against wind pressure can be ensured.

In the FRP sandwich panel method building according to the present invention, the joining member connecting adjacent FRP sandwich panels is a flat or L-shaped strip that is overlapped on the front and back over the edges of both adjacent FRP sandwich panels. It may be made of glass fiber reinforced plastic.
By using the joining member in this way as a flat or L-shaped strip, and using it on both the front and back sides, the FRP sandwich panel can be joined firmly and without any gaps for rainwater, wind, etc., In addition, the joining method is unified and workability is good. Further, when the joining member is made of glass fiber reinforced plastic, it is excellent in weather resistance and can be harmonized with the outer surface of the FRP sandwich panel.

In the FRP sandwich panel method building of the present invention, a panel with an opening having the same width and height as the flat FRP sandwich panel used for the outer wall may be provided on a part of the outer wall. The opening in the panel with an opening may be an opening serving as a doorway or a window opening.
By constructing the opening of the building with a panel with an opening having the same width and height as the FRP sandwich panel used for the outer wall in this way, an opening is provided on the outer wall by using a panel with an opening instead of the FRP sandwich panel. Can do. Therefore, an opening can be easily provided and the position of the opening can be easily selected.

In the FRP sandwich panel construction building according to the present invention, a roofing material of an arbitrary material may be provided on the roof made of the FRP sandwich panel.

As will be described later, these FRP sandwich panels have the same shape and the same specification, or the same shape and the same specification except for different lengths, floor 2 and outer wall 3, floor 2 and roof 4, etc. , Floor 2, outer wall 3, and roof 4.

  As shown in FIG. 11, the floor 2 of the two types of floor panels 5, 6 has a groove shape with an upward cross section, and the upper floor panel 6 has a flat shape, as shown in FIG. 11. . The flat floor panel 6 has a width twice that of the grooved floor panel 5 and is placed over the entire grooved floor panel 5 arranged side by side. The floor 2 is configured by arranging a plurality of floor panel groups 2a each composed of the two grooved floor panels 5 and one flat floor panel 6 side by side. The groove-shaped floor panel 5 is disposed on the ground GL, or is placed on a surface obtained by slightly excavating the ground GL to a depth within the height of the floor panel set 2a. The earth and sand 11 used as a weight is put in each groove-shaped floor panel 5. The earth and sand 11 may be sand, earth, gravel or stone.

  Although the roof 4 is configured by arranging the roof panels 10 as shown in FIG. 10, a roofing material 15 made of any material may be provided thereon. In the example of the figure, a metal folded plate is used for the roofing material 15. In addition to this, the roofing material 15 may be made of wood or other natural materials obtained in the construction area of the building 1.

  In FIG. 1, the outer wall 3 is provided with L-shaped wall panels 7 at the four corners so that the protruding corners face outward. A flat wall panel 8 or another L-shaped wall panel 7 is provided between the L-shaped wall panels 7 at both corners of each face of the outer wall 3, and in part, instead of the flat wall panel 8, A wall panel 9 with an opening is provided.

3 is a horizontal cross section of the entire building 1. FIG. 4 shows the IV-IV cross section of FIG. 3, and FIG. 5 shows the VV cross section. A front view, a left side view, a rear view, and a right side view of the building 1 are shown in FIGS. The building 1 in the figure is an example in which the dimensions in the horizontal direction and the depth direction are both six times the module length M. The module M has a length that is a standard dimension of the building 1 and is set to an appropriate length, for example, 1,000 mm or 900 mm.
As shown in FIG. 3, in this example, a groove-shaped core portion 12 composed of a set of two L-shaped wall panels 7 is formed at four corners. Each core portion 12 has a groove shape by arranging the same L-shaped wall panel 7 next to one side of the L-shaped wall panel 7 disposed at each corner. One side of the L-shaped wall panel 7 disposed next to the sleeve wall 7a protrudes indoors. Each of these core sections 12 is a facility core used as a place for installing sanitary facilities around the water such as a toilet, a bathroom, a kitchen, or a storage room.

  As shown in FIGS. 6 and 8, the wall panel 9 with an opening has the same width and height as the flat wall panel 8, and has an opening 13 serving as an entrance / exit or an opening 14 serving as a window. As shown in FIG. 6, the wall panel 9 with openings has one opening 13 in one wall panel 9, or a plurality of connections are made as shown in FIG. 8 to form one opening 14. It may be what you do. The opening 14 in the same figure becomes a discharge window.

  The wall panel 9 with an opening may have a wall portion, for example, a panel frame, a frame such as a sash, and a door, or may have a wall portion. The door may be a glass door or another door. In the case of the wall panel 9 with an opening having a wall portion, the wall portion is constituted by an FRP sandwich panel or the like.

  As FRP sandwich panels used as the other wall panels 7 and 8, the floor panels 5 and 6, and the roof panel 10 except for the wall panel 9 with the opening, cross-sectional shapes are shown in FIGS. 2 (A) to 2 (C). As shown respectively, three types of cross-sectional shapes and specifications of L-shaped FRP sandwich panel P1, flat FRP sandwich panel P2, and groove-shaped FRP sandwich panel P3 are prepared. The three types prepared are used for the floor 2, the outer wall 3, and the roof 4.

  In this example, the L-shaped FRP sandwich panel P1 is used only for the outer wall 2 as the wall panel 7, but the flat FRP sandwich panel P2 is formed on the floor 2 and the outer wall 3 as the upper floor panel 6 and the wall panel 8. The grooved FRP sandwich panel P3 is used for the floor 2 and the roof 4 as the lower floor panel 5 and the roof panel 10.

  However, flat FRP sandwich panels P2 having different lengths for the floor and the wall are prepared and used. For example, the flat FRP sandwich panel P2 for the wall has a length that becomes the ceiling height H (FIG. 10). The floor FRP sandwich panel P2 differs depending on the length of the floor 2 of the building 1. However, in the case of the building 1 of the plan shown in FIG. 3, the left and right and the depth are 6 times the module width M. The length is 3M, which is half of three modules, and the two are arranged in the longitudinal direction. As described above, the module dimension M is appropriately set to, for example, 900 mm, 1,000, etc. In this example, M = 1,000 mm, and the length of the flat FRP sandwich panel P2 for floor is 3 , 000 mm.

The length of the L-shaped FRP sandwich panel P1 is the same as the length of the FRP sandwich panel P2 for the wall panel 8 (in this example, 2.400 mm), and the length of the groove-shaped FRP sandwich panel P3 is The length of the floor 2 is 6,000 mm in this example.
Even if the panels having different lengths are counted as different types, the floor 2, the wall 3, and the roof 4 are all constituted by four types of FRP sandwich panels P1 to P3. If the ceiling height and floor length are designed so that the length of the floor 2 is a multiple of the ceiling height H, the flat FRP sandwich panel P2 can be of one type, and the number of types of FRP sandwich panels can be reduced. There are 3 types in total.

  Note that the smaller the number of types of FRP sandwich panels, the better the work efficiency and material cost reduction effect by reducing the number of types. The effect of cost reduction can be sufficiently obtained. For this reason, you may increase the number of types rather than the example of FIG. 2, such as making the cross-sectional shape of the FRP sandwich panel used by the floor 2 and the roof 4 differ.

As an example of the cross-sectional dimensions of the FRP sandwich panels P1 to P3, the L-shaped FRP sandwich panel P1 has a width M of one module on both sides (for example, 1,000 mm), and the flat FRP sandwich panel P2 has one module. The width is M. The width of the groove-shaped FRP sandwich panel P3 is a half width of the module, and is M / 2 (for example, 500 mm). The height h of the groove-shaped FRP sandwich panel P3 is set to an appropriate height (for example, 250 mm).
As for the thickness of each FRP sandwich panel P1 to P3, for example, the thickness of the core material 20 made of a heat insulating material is 50 to 60 mm, and the thickness of each surface layer 21 on both sides made of glass fiber reinforced plastic is 3 mm.
It is said to be about. Each of the FRP sandwich panels P1 to P3 preferably has a weight that can be carried by two workers, for example, about 80 kg or less.

  The material examples of the FRP sandwich panels P1 to P3 will be described. The FRP sandwich panels P1 to P3 are obtained by covering the entire core material 20 made of a heat insulating material with a surface layer 21 of glass fiber reinforced plastic. The heat insulating material to be the core material 20 is a foam of a heat insulating resin, such as polyurethane foam or polystyrene foam. The core material 20 made of this heat insulating material is preferably integrally molded from the viewpoint of strength and the like even when it is L-shaped or groove-shaped.

  As an example of the manufacturing method of each FRP sandwich panel P1 to P3, as shown in FIG. 14, a heat insulating material 20A made of a long strip is prepared, and from this material 20A, the FRP sandwich panels P1 to P1 are prepared. It is obtained by cutting the core material 20 made of a heat insulating material having a length L which is the entire length of P3. A method called hand lay-up or the like on the surface of the core material 20, that is, a method of forming the surface layer 21 by spreading a glass fiber, applying a paint using a roller or a brush (not shown), and drying the coating. Is taken. At the time of coating, a method is adopted in which the surface layer 21 is coated on one side facing upward as shown in FIG. 14B, and then the remaining surface is coated upside down as shown in FIG. 14C. . It may be performed in multiple layers by repeating the application of one side and the operation of applying the remaining one side by reversing.

  FIGS. 12A to 12D show configuration examples of the connecting portions of the FRP sandwich panels P1 to P3, respectively. For the connection, a flat plate-shaped bonding member 23 or an L-shaped bonding member 24 is used which is overlapped on the front and back sides of the edges of adjacent FRP sandwich panels P1 to P3. Each of the joining members 23 and 24 is a plate-like strip material, made of glass fiber reinforced plastic, and provided over the entire length of the sides to be joined. When the dimension example of the joining members 23 and 24 is given, for example, they are 90 × 4 and 75 × 75 × 4 (the unit is mm), respectively. The joining members 23 and 24 stacked on the FRP sandwich panels P1 to P3 are screwed or driven into the FRP sandwich panels P1 to P3 with a nail-like fixing tool 25 such as a tapping screw, for example, so as to penetrate the joining members 23 and 24. Join with. The fixing tool 25 is provided with an interval at which the joining members 23 and 24 are in close contact with each other using a waterproof tape or the like so that rainwater does not enter from the joining portion. Instead of using the nail-like fixing tool 25, it may be bonded with an adhesive, or the nail-like fixing tool 25 and an adhesive may be used in combination.

FIG. 12A shows a mutual connection portion of the flat FRP sandwich panel P2, for example, a joint portion between the flat wall panels 8, and a flat joint member 23 is overlapped on both surfaces. A connecting portion for connecting the flat FRP sandwich panel P1 to the end of the L-shaped FRP sandwich panel P1 is also connected in the same manner as in FIG.
FIG. 12B shows a joint that joins the outer surface of one side of the L-shaped FRP sandwich panel P1 by abutting the end of the flat FRP sandwich panel P2 so as to be aligned with the other side. Specifically, it is a joint between the wall panel 7 and the wall panel 8. In this joining portion, a flat joining member 23 is provided on the outside and an L-shaped joining member 24 is provided on the inside corner.

  FIG. 12 (C) shows a joint where the flat or L-shaped FRP sandwich panels P2 and P1 are joined to the lower surface of the upward groove-shaped FRP sandwich panel P3. Specifically, it is a joint (the XIIC part in FIG. 11) that joins the wall panels 7 and 8 to the lower surface of the roof panel 10. Also in this joining portion, a flat joining member 23 is provided on the outer side, and an L-shaped joining member 24 is provided on the inner corner.

  FIG. 12 (D) shows a joint for joining the flat or L-shaped FRP sandwich panels P2 and P1 to the upper surface of the flat FRP sandwich panel P2. Specifically, it is a joint (the XIID section in FIG. 11) that joins the wall panels 7 and 8 to the upper surface of the upper floor panel 6. Also in this joining portion, a flat joining member 23 is provided on the outer side, and an L-shaped joining member 24 is provided on the inner corner. However, the flat joint member 23 has a width that projects downward from the lower surface of the floor panel 6 to ensure the prevention of rainwater intrusion.

Next, a construction procedure will be described with FIG. First, the lower floor panel 5 is installed on the ground GL (S01). After putting the earth and sand 11 (FIG. 11) used as a weight in this floor panel 5, the upper floor panel 6 is installed (S02).
L-shaped wall panels 7 at each corner are installed (S03). When the core part 12 is comprised by the two wall panels 7, both L-shaped wall panels 7 which comprise the core part 12 are installed.

  Thereafter, the head connecting material 26 for connecting the upper ends of the wall panels 7 is installed (S04). The head connecting material 26 may be the joint members 23 and 24 that join the wall panels 7 to 9 and the roof panel 10, or may be provided separately from the joint members 23 and 24. . Next, a flat wall panel 8 and a wall panel 9 with an opening are installed (S05).

The roof panel 10 is installed on this (S06). Thus, after installing each panel 5-10 of the floor 2, the outer wall 3, and the roof 4, the said joining members 23 and 24 between the panels (the joining member 24 does not appear in FIG. 13) are installed. S07).
Finally, the roofing material 15 according to local specifications is installed on the roof panel 10 (S08), and the main body portion excluding the equipment and piping of the building 1 is completed (S09).

According to the FRP sandwich panel construction building 1 having the above configuration, the FRP sandwich panels P1 to P3 serve as the structure of the building 1 and the interior and exterior. Since the outer wall 3, the floor 2 and the roof 4 are all constituted by the FRP sandwich panels P1 to P3 which also serve as the structure and the interior and exterior, the building 1 can be constructed only by connecting the FRP sandwich panels P1 to P3. . Since the surfaces of the FRP sandwich panels P1 to P3 are excellent in weather resistance and are beautiful, it is possible to omit coating as an exterior, cross bonding as an interior, and the like. Further, the FRP sandwich panels P1 to P3 can be made into panels having the necessary strength and heat insulation on the building structure by using foamed resin or the like for the core material 20, and can be made into lightweight panels, and have the necessary size. With the necessary strength, it can be stored in a weight that can be transported manually. Moreover, it can be produced by applying a surface layer 21 of glass fiber reinforced plastic by manual application or the like to the core material 20 cut to a predetermined length on site or prepared as a predetermined length. Therefore, no special manufacturing machine is required.
The FRP sandwich panels P1 to P3 have a cross-sectional shape of any one of an L shape, a flat shape, and a groove shape, and depending on the combination, all of the outer wall 3, the floor 2, and the roof 4 are formed. It can be configured and the number of types is small.

In this way, the outer wall 3, the floor 2, and the roof 4 can all be constituted by the FRP sandwich panels P1 to P3, the number of types of building materials can be reduced, the joining structure of each part can be unified, and each FRP sandwich panel P1 to P3. Because it can be made lightweight, no special assembly equipment or special construction techniques are required, and anyone can easily build and have excellent workability. The FRP sandwich panels P1 to P3 themselves can be easily manufactured at a construction site by preparing the core material 20 and the coating FRP without requiring a special manufacturing machine. It is not necessary to prepare finished products of sandwich panels P1 to P3. From these, according to this FRP sandwich panel construction method building 1, it becomes possible to supply a large amount in a short time when a large-scale natural disaster occurs.
In addition, temporary housing in Japan and housing that requires a large amount of supply in developing countries have a common level of requirements. Therefore, by sharing them, domestic and developing countries can supply each other as needed. Can fit.

In this way, it can be constructed with low cost, a short construction period, and easy construction, and the production of the main members can be easily performed locally, and a large amount can be supplied in a short period of time.
Moreover, since FRP sandwich panels P1-P3 using the core material 20 which consists of heat insulating materials are excellent also in heat insulation, the weather resistance of a surface layer, and designability, it leads also to the improvement of the living environment corresponding to cost.

Further, since the same FRP sandwich panels P1 to P3 are used at a plurality of locations of the outer wall 3, the floor 2 and the roof 4, the number of types of FRP sandwich panels P1 to P3 can be reduced. In this embodiment, there are three types of cross-sectional shapes, and there are four types including the difference in length. As described above, since the number of types of the FRP sandwich panels P1 to P3 is reduced, it is possible to realize simple construction by improving the production efficiency of the FRP sandwich panels P1 to P3 and by unifying the joining work by unifying the shapes. When each type of FRP sandwich panels P1 to P3 are all set to the same width or a multiple of the reference width as described above, production efficiency can be further improved.
The lengths of the FRP sandwich panels P1 to P3 are preferably unified into one type, but the number of types may be increased to about two types as described above. When producing FRP sandwich panels P1 to P3, the long heat insulating material 20A (FIG. 14) is prepared as described above, and is produced by cutting to the required length and applying glass fiber reinforced plastic.

Thus, the occupied area and the efficiency of the floor plan can be improved. Although the core part 12 does not necessarily need to be provided, by providing the core part 12 as described above, the strength of the building 1 can be improved and the facility arrangement space can be formed simultaneously.

  Moreover, when the floor 2 is constituted by the groove-shaped FRP sandwich panel P3 and the flat FRP sandwich panel P2 as described above, the earth and sand 11 which becomes a weight can be put therein, thereby stabilizing the building 1. At the same time, durability against wind pressure can be provided.

  Since the joining members 23 and 24 are made of strips or L-shaped strips that are overlapped on the front and back over the edges of the adjacent FRP sandwich panels P1 to P3, gaps for rainwater, wind, etc. can be eliminated. It can be done, and the workability is good because the joint type is unified. Moreover, when the joining members 23 and 24 are made of glass fiber reinforced plastic, the weather resistance is excellent, and harmony with the outer surfaces of the FRP sandwich panels P1 to P3 can be obtained.

  When the openings 13 and 14 of the building 1 are configured with the panel 9 having the same width and height as the FRP sandwich panel P2 used for the outer wall 3, the outer wall can be obtained by using a panel with an opening instead of the FRP sandwich panel P2. 3 can be provided with openings 13, 14. Therefore, the openings 13 and 14 can be easily provided, and the openings 13 and 14 can be easily selected.

  The roof 4 may be composed of only the FRP sandwich panel P3. However, providing the roofing material 25 according to the climate of the area according to the area to be installed improves the living environment against rainfall and the like.

  Each of the FRP sandwich panels P1 to P3 is formed by applying uncured glass fiber reinforced plastic to the core material 20 made of a heat insulating material to form a surface layer 21 as described above. It is a shape, has the strength required for walls and floors as a temporary housing structure, and is a weight that can be carried by two workers. Thus, since the glass fiber reinforced plastic of the surface layer 21 is applied by application | coating, it can manufacture manually. Furthermore, since it is a weight that can be carried by two workers, it is not necessary to use heavy machinery during transportation and installation, and construction can be performed even in developing countries and in disasters.

In the above-described embodiment, the core portion 12 provided at the corner of the building 1 is formed in a groove shape by the two L-shaped wall panels 7. However, like the core portion 12A in FIG. Further, the L-shaped wall panel 7 and the flat wall panel 8 may be added to form a box-shaped core portion 12A, and a part of the interior wall may be the opening 16.
Moreover, like the one part core part 12B of FIG. 16, the flat wall panel 8 may be added between the two L-shaped wall panels 7 in the outer wall 3 to form a large box-shaped core part 12B.

  FIG. 17 shows a building 1 </ b> A that is a continuous building type having a plurality of units (three in the example shown in FIG. 3) and a plurality of dwelling units. In this case, the partition wall 3A of the partition wall panel 8 is omitted from the adjacent unit 1 of the building 1 to save the members as a single layer. In this way, the building 1 </ b> A that becomes the dwelling unit of the continuous building and the detached building 1 can be constructed with the same member.

  FIG. 18 shows this further embodiment. In this embodiment, the floor 2 is constituted by an array of two L-shaped floor panels 5A and 6A that are vertically assembled in a box shape. These two floor panels 5A and 6A have the same configuration, and the FRP sandwich panel P1 having the same shape and specifications is used except that the outer wall 3 is different in length from the L-shaped wall panel 7 of the configuration. Sediment 11 (not shown in FIG. 18) is placed in the box-shaped set of floor panels 5A and 6A in the same manner as in the above embodiment. In this example, a roof panel 10A made of a groove-shaped FRP sandwich panel dedicated to the roof is used for the roof 4.

  In the case of this configuration, the FRP sandwich panel P1 having the same cross-sectional shape is used for the floor panels 5A and 6A of the floor 2 and the wall panel 7 of the outer wall 3, and the number of member types is reduced. A dedicated roof panel 10A is used. Other configurations and effects are the same as those of the first embodiment described with reference to FIGS.
