Description

The present invention relates to a simple assembled house that is constructed by assembling a plurality of panel bodies to form a three-dimensional structure.

BACKGROUND ART Conventionally, there have been prefabricated houses in which a plurality of panel bodies are assembled to form a three-dimensional space for the purpose of constructing a simple changing room, an emergency medical room, etc. inside a building or outdoors. Such prefabricated houses often use lightweight panel bodies made of synthetic resin or the like, and can be relatively easily assembled without requiring special knowledge, and can be easily transported in a disassembled state.

For example, the assembled house disclosed in Patent Document 1 has a plurality of vertically long panel bodies connected in the width direction, and both sides of these panel bodies are connected in the vertical direction with connecting fittings to form a cylindrical body. An upper end metal fitting is attached to the ceiling side of the cylindrical body, that is, the upper end of the panel body to form a three-dimensional structure.

JP-A-5-295907 (Page 2, Figure 1)

The uses for such prefabricated houses are wide-ranging, and for buildings that require a particular height, such as those in Patent Document 1 where people stay for a specified period of time, it is necessary to prevent the three-dimensional structure from collapsing. In Patent Document 1, an upper end metal fitting is provided on the ceiling side, and a cross metal fitting, which is a rigid body in the shape of a cross, is fixed to the upper end metal fitting to ensure the strength of the ceiling part. By having a frame structure consisting of rigid bodies such as these upper end metal fittings and cross metal fittings, it is possible to effectively prevent horizontal deformation of the cylindrical connected panel body, but it does not increase the weight on the ceiling side. , vertical columns are required to support this. In Cited Document 1, both side edges of the panel body are connected by connecting fittings extending in the vertical direction, and this connecting fitting made of a rigid body functions as a vertical column. The original purpose of prefabricated houses was to be easy to transport, but in Cited Document 1, as mentioned above, the frame structure and pillars are required, which makes the assembly work complicated, and the weight makes it difficult to carry. The problem was that it was difficult.

The present invention has been made in view of these problems, and an object of the present invention is to provide a prefabricated house that has a simple structure and can ensure sufficient structural strength.

In order to solve the above problems, the prefabricated house of the present invention has the following features:
A prefabricated house in which a plurality of panel bodies are connected to form a self-supporting three-dimensional structure,
The panel bodies each constitute a ceiling and a floor made of hollow plate materials, and a plurality of side wall panels connected to form a cylindrical body,
The ceiling has a bending piece along the outer edge, and the bending piece is fixed to the left and right by a plurality of connecting means in a state where it overlaps the upper edge of the side wall panel,
The floor has a bending piece along the outer edge, and the bending piece is fixed to the left and right by a plurality of connecting means in a state of being superimposed on the lower edge of the side wall panel.
According to this feature, by fixing the folded piece along the outer edge of the ceiling to the upper edge of the side wall panel, the folded piece can function as a frame that follows the outer shape of the ceiling and increase its strength. By fixing the bent piece along the outer edge of the floor to the lower edge of the side wall panel, the bent piece functions as a frame that follows the outer shape of the floor, increasing its strength. Therefore, while preventing an increase in the load on the ceiling, it is possible to effectively prevent the deformation of the cylindrical body formed by the side wall panels connected between the ceiling and the floor, and to maintain sufficient structural strength to maintain the three-dimensional structure. It can be secured. In addition, a three-dimensional structure that secures structural strength can be achieved with a simple structure in which the ceiling folding piece and the floor folding piece are each fixed to the side wall.

The hollow plate material is characterized in that a large number of hollow air bubbles are evenly arranged between the front plate and the back plate.
According to this feature, the hollow plate material is strong against bending deformation in both the vertical and lateral directions, so that weak parts are not unevenly distributed in the three-dimensional structure.

The side wall panel is composed of a plurality of panel bodies that are connected from side to side, and the sides of the adjacent panel bodies are connected at a plurality of places in the vertical direction by joint panels made of hollow plates overlapped vertically and connecting means. It is characterized by being fixed at
According to this feature, the structural strength of the cylindrical body formed by the side wall panel can be increased by arranging a plurality of lightweight joint panels made of hollow plate material in the vertical direction.

The joint panel is characterized in that its upper end contacts the lower end of the folded piece of the ceiling, and its lower end contacts the upper end of the folded piece of the floor.
According to this feature, the load on the ceiling side is supported on the floor side via the joint panel, so the load on the ceiling side is less likely to be applied to the side wall panel, and the deformation of the cylindrical body formed by the side wall panel is prevented over a long period of time. can be effectively suppressed.

It is characterized in that an exhaust port and an air supply port are formed to face each other on both sides of the side wall panels facing each other across the interior of the prefabricated house.
According to this feature, since the exhaust port and the air supply port are formed to face each other, the indoor air ventilation capacity is high and the comfort is excellent.

A plurality of the exhaust ports and the air supply port are arranged in parallel near the bent piece of the ceiling body, and the joint panel is disposed with the exhaust port and the air supply port sandwiched therebetween. It is a feature.
According to this feature, a plurality of exhaust ports and air supply ports are installed in parallel above the prefabricated house, increasing the ventilation capacity of indoor air while forming these exhaust ports and air supply ports to strengthen the structure. The part of the side wall panel where the strength has decreased is located in a downward U-shaped area with increased strength made up of a pair of joint panels and a bent piece, so an exhaust port and an air supply port are formed. There is less impact on structural strength due to this.

One hole 10 is formed in each section. A hole 10 is formed in the upper and lower ends of the side panels 41B and 41C at the center in the left-right direction.

As shown in FIG. 3, the bent pieces 23A and 23B of the ceiling 2 and the bent pieces 33A to 33C of the floor 3 have one hole 10 formed at each of the left and right ends. The holes 10 formed in the bent pieces 23A and 23B of the ceiling 2 are arranged at positions corresponding to the holes 10 formed in the upper ends of the side wall panels 4A to 4C, and the bent pieces 33A of the floor 3 The holes 10 formed in the side wall panels 4A to 4C are located at positions corresponding to the holes 10 formed in the lower ends of the side wall panels 4A to 4C.

Next, the connecting means 12 will be explained using FIG. 6. As shown in FIG. 6(a), the connecting means 12 is composed of a base member 13 and an operating member 14. A hole 13a is formed in the approximate center of the base member 13, and extends through the hole 13a from front to back, and the operating member 14 is rotatably inserted into the hole 13a.

The base member 13 includes a rectangular plate portion 130, and insertion pieces 13b, 13b that respectively protrude from the back side so as to surround the hole portion 13a, and locking claws 13c, 13c. The insertion piece 13b has a horizontal dimension that is approximately the same as the horizontal width of the hole 10, and a distance between the upper and lower ends of the opposing insertion pieces 13b, 13b is approximately the same as the upper and lower width of the hole 10. be.

The locking claws 13c, 13c are close to each other in a natural state, and the distance between the left and right ends of the opposing locking claws 13c, 13c is approximately the same as the left-right width of the hole 10, and They are each pushed outward by the rotational operation, and are configured to be larger than the left and right width of the hole 10.

As shown in FIG. 6(b), the operating member 14 includes a knob 14a on the front side and a mountain portion 14b having a linear peak on the back side. Convex portions 13d, 13d are formed on the opposing surfaces of the locking claws 13c, 13c, respectively, and depending on the phase of the operating member 14, these convex portions 13d, 13d are located in the valley portions 14c, 14c of the peak portion 14b, respectively. Then, the locking claws 13c, 13c are positioned on the proximal side. By rotating the operating member 14 from this state, the protrusions 13d, 13d of the locking claws 13c, 13c are guided to a position where they come into contact with the side surface 14d of the operating member 14. Each is pushed outward. As a result, the locking claws 13c, 13c are in a state where they cannot be removed from the hole 10. The connecting means 12 inserts the insertion pieces 13b, 13b and the locking claws 13c, 13c into the overlapping holes 10, 10 of the panel bodies or the joint panel 5, and rotates the operating member 14 to open the locking claws. 13c, 13c cannot be removed from the holes 10, 10, so that the panel bodies and the joint panel 5 can be connected and fixed.

Next, a procedure for assembling the ceiling 2, floor 3, and cylindrical body 4 will be explained. First, the side wall panels 4A and 4C constituting the cylindrical body 4 are assembled on the floor 3. Before this assembly, the panel bodies are connected using the joint panel 5 and the connecting means 12 to form the side wall panels 4A, 4C. The panel bodies 3A and 3B of the floor 3 are made to stand upward by bending the folding pieces 31A and 31C and the folding pieces 33A and 33C at right angles to the base parts 30 and 32 with the folding part BE as the base point, These bent pieces are superimposed on the lower ends of the side wall panels 4A and 4C, respectively.

Next, auxiliary frames 50 (see FIG. 2) are attached to both sides of the side wall panels 4A, 4C. The auxiliary frame 50 is a long member formed by bending aluminum and has an L-shaped cross section, and is simply fixed to the back side of both sides of the side wall panels 4A, 4C with an adhesive, such as double-sided tape. Ru. Although this auxiliary frame 50 itself has almost no function in terms of the structural strength of the assembled house 1, it makes it easier to temporarily stand up the side wall panels 4A, 4C to which the auxiliary frame 50 is attached. The work efficiency when fixing the folding pieces 31A, 31C and the folding pieces 33A, 33C of the panel bodies 3A, 3B can be improved.

The bent pieces 31A, 31C and the bent pieces 33A, 33C of the upright panel bodies 3A, 3B are superimposed on the lower ends of the side wall panels 4A, 4C, and aligned so that the holes 10 are overlapped front and back, They are each fixed by connecting means 12. In this way, by fixing the bent pieces 31A, 31C and the bent pieces 33A, 33C to the side wall panels 4A, 4C, the panel bodies 3A, 3B are connected, and the floor 3 of a predetermined size is configured.

As shown in FIG. 7, the joint panel 5 that connects the center panel 40A and the side panels 40B, 40C has a vertical dimension shorter than that of the center panel 40A and the side panels 40B, 40C. In this state, the upper and lower ends 5a and 5b are located closer to the center than the upper and lower ends of the center panel 40A and the side panels 40B and 40C, respectively, in a state where they are connected using the hole 10.

The distance L2 from the lower end 40F of the center panel 40A and side panels 40B, 40C to the lower end 5b of the joint panel 5 and the dimension L1 in the extending direction of the bent piece (see FIG. 3) are as follows: They are approximately the same size. Incidentally, all of the bent pieces (the bent pieces 21A to 21C, the bent pieces 23A, 23B, and the bent pieces 25A to 25C) have the same dimension L1 in the extending direction.

Next, the ceiling 2 is assembled. Recesses 45 (see FIGS. 5(a) and 5(c)) are formed at the upper ends of the side wall panels 4A, 4C on the left and right sides of the center, respectively. Ceiling frames 51, 51 are installed in the recesses 45 of these opposing side wall panels 4A, 4C, respectively. The ceiling frame 51 is made of aluminum and formed into a plate shape, and its vertical dimension is approximately equal to the depth dimension of the recess 45 .

One ceiling frame 51 is disposed below the end where the side 20d of the panel body 2A and the side 22c of the panel body 2B abut against each other, and the other ceiling frame 51 is disposed below the edge 20d of the panel body 2A and the side 22c of the panel body 2B. The panel body 2C is disposed below the end portion where the panel body 2C abuts against the side 24d, and can support the panel bodies 2A to 2C from below. Since the ceiling frames 51, 51 are arranged only at the boundaries between the panel bodies 2A to 2C, they can effectively prevent the boundaries of the panel bodies 2A to 2C from sagging with the minimum necessary configuration, and can also prevent sound leakage. and prevent light leakage.

Next, the panel bodies 2A to 2C are placed on the upper ends of the side wall panels 4A and 4C, and the hanging bent pieces 21A and 21C, the bent pieces 23A and 23B, and the bent pieces 25A and 25C are overlapped, and the holes 10 are overlapped. are aligned so that they overlap front and back, and each is connected using a connecting means. In this way, by fixing the bending pieces 21A, 21C, the bending pieces 23A, 23B, and the bending pieces 25A, 25C to the side wall panels 4A, 4C, the panel bodies 2A to 2C are connected, and a ceiling 2 of a predetermined size is connected. is configured.

The distance L2 from the upper end 40R of the center panel 40A and side panels 40B, 40C to the upper end 5a of the joint panel 5 and the dimension L1 in the extending direction of the bent piece are approximately the same size. ing.

Next, the side wall panels 4B and 4D are assembled to what has been assembled so far. First, the panel bodies are connected using the joint panel 5 and the connecting means 12 to form the side wall panels 4B and 4D. The panel bodies 3A, 3B constituting the floor 3 are formed by bending the bent pieces 31B, 33B at right angles to the base portions 30 and 32, using the folded portion BE as a base point, and standing upright to form the side wall panels 4B, 4D. Polymerize with the lower end of each.

The panel bodies 2A, 2C constituting the ceiling 2 have hanging bent pieces 21B, 25B superimposed on the upper ends of the side wall panels 4B, 4D. Then, the holes 10 of the bent pieces 31B, 33B of the floor 3 and the bent pieces 21B, 23B of the ceiling 2 are aligned so as to overlap with the holes 10 of the upper ends of the side wall panels 4B, 4D, and the connecting means 12 are aligned, respectively. Connect with.

Next, both sides of the side wall panels 4B and 4D are simply fixed to the auxiliary frame 50 with adhesive. As a result, the three-dimensional shape is temporarily maintained, making it easier to perform the fixing work using the connecting means 12 to connect the side wall panels 4B, 4D to the ceiling 2 and floor 3.

The distance L2 from the upper end 41R of the center panel 41A and the side panels 41B, 41C that constitute the side wall panel 4B to the upper end 5a of the joint panel 5, and the lower end 41F of the center panel 41A and the side panels 41B, 41C. The distance L2 from the bottom end 5b of the joint panel 5 to the bottom end 5b of the joint panel 5 and the dimension L1 in the extending direction of the bent piece are approximately the same.

As described above, by fixing the folding pieces 21A to 21C, the folding pieces 23A and 23B, and the folding pieces 25A to 25C along the outer edge of the ceiling 2 to the upper edge of the cylindrical body 4, The curved piece functions as a frame that follows the outer shape of the ceiling 2, increasing its strength. Similarly, the bent pieces 31A to 31C and the bent pieces 33A to 33C along the outer edge of the floor 3 are fixed to the lower edge of the cylindrical body 4. The strength can be increased by acting as a Thereby, deformation of the cylindrical body 4 connected between the ceiling 2 and the floor 3 can be effectively prevented. Further, sufficient structural strength to maintain the three-dimensional structure can be ensured while preventing an increase in the load on the ceiling 2. In addition, a simple structure in which the folded pieces of the ceiling 2 and the folded pieces of the floor 3 are each fixed to the cylindrical body 4 can provide a three-dimensional structure that ensures structural strength.

Further, each of the side wall panels 4A to 4D is composed of a plurality of panel bodies connected to the left and right, and the side parts of the adjacent panel bodies are connected to a joint panel 5 made of hollow plate materials overlapped vertically. It is fixed at a plurality of locations vertically by means 12. By arranging a plurality of lightweight joint panels 5 made of hollow plate material in the vertical direction in this manner, the structural strength of the cylindrical body 4 formed by the side wall panels 4A to 4D can be increased. In addition, the side wall panels 4A to 4D are divided to improve portability.

In addition, the joint panel 5 has its upper end 5a in contact with the lower end 2R of the folding pieces 21A, 21C, folding pieces 23A, 23B, and folding pieces 25A, 25C of the ceiling 2, and its lower end 5b contacts the lower edge 2R of the folding pieces 21A, 21C, 23A, 23B, and 25A, 25C of the ceiling 2. The bending pieces 31A to 31C and the bending pieces 33A to 33C are in contact with the upper ends 3F, and the load on the ceiling 2 side is supported by the floor 3 side via the joint panel 5, so that the load on the ceiling 2 side is reduced. is less likely to hang on the cylindrical body 4, and deformation of the cylindrical body 4 can be effectively suppressed over a long period of time.

Further, the bent pieces of the ceiling 2 and the bent pieces of the floor 3 are each fixed by a connecting means 12 so as to straddle between the panel bodies constituting the divided side wall panels 4A to 4D, respectively. Therefore, the integrity of these panel bodies can be improved.

Next, the hollow plate materials forming each panel body will be explained using FIG. 10. The ceiling 2, the floor 3, the side wall panels 4A to 4D, and the joint panel 5 in this embodiment are constructed from similar hollow board panel bodies, and FIG. 10 shows a part of the panel body constituting any of them. It will be explained as follows. Incidentally, for convenience of explanation, the panel body 15 will be explained.

As shown in FIG. 10(a), the panel body 15 is made of synthetic resin and has a liner, which is a flat exterior material, on both the front and back sides of a cap sheet 60, which is a core material that has three-dimensional processing to form a hollow structure. A sheet 61 and a back sheet 62 are each laminated.

Specifically, a large number of hollow protrusions 63 are formed on the surface of the cap sheet 60. The cap sheet 60 has, for example, a large number of protrusions 63 that expand into a hollow shape by contacting the outer peripheral surface of a forming roll provided with a large number of cavity holes (not shown) with molten resin that is continuously fed out in a sheet form. Vacuum formed.

In the cap sheet 60, a back sheet 62 is laminated on the opening side of the protrusion 63, a liner sheet 61 is laminated on the top side of the protrusion 63, and the cap sheet 60 is sandwiched between the back sheet 62 and the liner sheet 61. Laminated and integrated by heat fusion. Thereby, the panel body 15 is formed.

Further, as shown in FIG. 10(b), a resin sheet 64 may be adhered to the cut end surface of the panel body 15. According to this, deformation of the end faces of the panel bodies 15 that are abutted against each other can be prevented, and the structural strength of the prefabricated house 1 can be easily maintained.

Note that the method for forming the panel body 15 is not limited to the above. Examples of the material resin for the panel body 15 include polyolefin resins such as polypropylene and polyethylene, polystyrene resins such as polystyrene, polyester resins such as polyethylene terephthalate, and polyamide resins such as nylon. However, it is not limited to these.

The folded pieces (folded pieces 21A to 21C, folded pieces 23A and 23B, folded pieces 25A to 25C, folded pieces 31A to 31C, and folded pieces 33A to 33C) are formed by subjecting the panel body 15 to a predetermined process. It is formed by Note that, for convenience of explanation, the bent piece 16 will be described here. As shown in FIG. 12, by making a cut (so-called half-cut) at a predetermined location on either the back sheet 62 side or the liner sheet 61 side, and bending the remaining other side using the cut location as a reference point. , forming a folded portion BE. Thereby, the free end of the panel body 15 becomes a bent piece 16 along this folded portion BE.

In this embodiment, the folding portion BE is formed on the liner sheet 61 side by making a cut on the back sheet 62 side, and the folding piece 16 can be bent from the back sheet side to the liner sheet side. That is, the bases of the panel bodies constituting the ceiling 2 or the floor 3 are arranged such that the liner sheet 61 is located inside the space and the back sheet 62 is located outside the space.

FIG. 11 is an enlarged view of the panel body 15 viewed from the liner sheet 61 side, and in the area where the projection 63 is not present, a cut is made so that the fused portion between the cap sheet 60 and the back sheet 62 is cut. According to this, only the liner sheet 61 is bent, and as shown in FIG. 12(a), a cut is made in the area where the protrusion 63 is located so that the back sheet 62 and the side wall of the protrusion 63 are cut. As shown in FIG. 12(b), the portion where the top surface of the protrusion 63 is fused to the liner sheet 61 is bent to form a folded portion BE.

In this way, the folded portion BE is formed by alternately arranging a portion consisting only of the liner sheet 61 and a portion having a double structure in which the top surface of the protrusion 63 is fused to the liner sheet 61. It turns out. Therefore, the folded portion BE formed by making the cut is partially reinforced by the double structure portion in which the top surface of the protrusion 63 is fused to the liner sheet 61, making it easier to bend the folded portion BE. The strength has been increased to the extent that the quality is not compromised. That is, in order to reinforce the folded part BE, for example, if the folded part is simply laminated with sheet materials to form a double structure at the part where the folded part is to be formed, the folded part becomes difficult to bend, making it difficult to assemble the panel body 15. However, in this embodiment, since the folded part BE has a partially double structure, the folded part BE is appropriately reinforced without impairing its bendability. , it is possible to achieve both lightweight and structural strength.

As shown in FIG. 2, ventilation holes 43 are formed in opposing side wall panels 4B and 4D, respectively, across the interior of the prefabricated house. On the side wall panels 4B and 4D, three pieces are arranged in parallel near the folding pieces 21B and 25B on the ceiling 2 side, respectively. This increases the indoor air ventilation capacity.

A blower device (not shown) is attached to each of the ventilation holes 43 . A blower is installed on one of the side wall panels 4B, 4D to blow air toward the indoor side, forming an air supply port, and a blower is installed on the other side to blow air toward the outdoor side, forming an exhaust port. has been completed. According to this, since the exhaust port and the air supply port are formed to face each other indoors, the indoor air ventilation capacity of the prefabricated house 1 is high, and the livability is excellent. This is particularly useful when the assembled house 1 is used as a gaming booth, for example, because it can efficiently discharge exhaust heat from the computer and bring in air from the indoor air conditioner to maintain a comfortable room temperature.

Further, at the same height position as the exhaust port and the air supply port, a connecting means 12 and a corresponding hole 10 between the central panel 41A and the side panel 41B, a connecting means 12 and a corresponding hole 10 between the central panel 41A and the side panel 41C, and a corresponding hole 10 are provided. A hole 10 is located there. Therefore, the connection point between the center panel 41A and the pair of joint panels 5, 5 is located at the upper part of the center panel 41A where the exhaust port and the air supply port are formed, so that the exhaust port and the air supply port are connected to each other. The load of the attached blower device can be distributed to the pair of joint panels 5, 5 and the side panels 41B, 41C, effectively preventing deformation and damage to the exhaust port and air supply port, and preventing vibration of the blower device. It can achieve sufficient structural strength to withstand resistance and can be held securely.

Further, a plurality of these exhaust ports and air supply ports are arranged in parallel near the bent piece on the ceiling 2 side, and a pair of joint panels 5, 5 are arranged with the exhaust port and the air supply port in between. Therefore, a part of the side wall panel whose strength has been reduced due to the formation of these exhaust ports and air supply ports is replaced by a downward U-shaped structure with increased strength made up of a pair of joint panels 5, 5 and a bent piece. Since the vent hole 43 is located in the region of 1, the structural strength is less affected by the formation of the vent hole 43.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any changes or additions that do not depart from the gist of the present invention are included in the present invention. It will be done.

For example, in the above embodiment, the panel bodies are connected and fixed by the connecting means 12 and the hole 10, but this is not the only example, and various connecting structures can be adopted. Needless to say, for example, the door panel 11 may be attached to the center panel 40A so that its vertical position can be adjusted, so that the distance from the floor of the room can be adjusted.

Further, the ceiling 2, the floor 3, and the side wall panels 4A to 4D may each be integrated instead of having a separate structure, and in that case, a plurality of folded parts may be formed to form a folding structure to facilitate transportation.

Further, the auxiliary frame may be omitted since it has almost no function in increasing the structural strength of the prefabricated house 1.

Similarly, regarding the ceiling frame, it is intended to prevent sagging near the boundaries of the panel bodies 2A to 2C, and since it has almost no effect on the structural strength of the prefabricated house 1, for example, each boundary of the panel bodies 2A to 2C is The ceiling frame may be omitted by joining the ceilings with a wire, etc., to prevent sound and light leakage.

In addition, through holes may be formed in the side wall panels 4A to 4D for leading the wiring into the assembled house 1, and in order to suppress a decrease in strength, the through holes are located at positions corresponding to the joint panels 5. It is preferable to provide the through hole in the joint panel 5 side and communicate with the through hole formed on the joint panel 5 side.
