Description

[Technical field]

[0001] The present invention relates to a frame unit, and more particularly to a frame unit that can easily form a partition framework in evacuation shelters and event spaces in the event of a disaster. [Background technology]

[0002] Conventionally, various simple partitions and partition units have been disclosed from the viewpoint of ensuring privacy in evacuation sites during disasters (see, for example, Patent Documents 1 to 3). The prefabricated partition disclosed in Patent Document 1 has a plurality of pillar members and a plurality of crosspiece members, and the pillar members and the crosspiece members are selectively combined and detachably connected to each other to form a frame body, which divides a space. According to the prefabricated partition disclosed in Patent Document 1, a large room or plaza such as a gymnasium or community center can be divided to form a large number of small rooms, and it is described that when a large number of disaster victims share a large room or plaza during evacuation life, privacy is ensured as much as possible even when living in a common large space, and stress for the victims is reduced.

[0003] The document also describes that since a frame body is formed by selectively combining multiple pillar members and multiple batten members and removably connecting them to each other, and this frame body is used to divide a room, etc., the pillar members and batten members can be easily transported to the installation location as they are, and that assembly can be completed simply by connecting the batten members by inserting them into the pillar members, so that assembly can be completed quickly and easily without requiring skill, and that small rooms, etc. made up of frame bodies can be increased one after another by simply adding pillar members and batten members.

[0004] The partition unit disclosed in Patent Document 2 comprises a square tubular structure made of a square paper tube, and a joint mechanism for connecting the structures together, and the joint mechanism is a mechanism in which a third structure attached to either a first structure or a second structure which are connected to each other in the structures can be fitted into the other of the first structure or the second structure.

[0005] It is described that the partition unit disclosed in Patent Document 2 is less likely to roll than a partition using a cylindrical member made of a round paper tube, making it possible to stably place and store the unit, and improving the handleability of the partition. It is also described that because a square paper tube, which is lighter than a round paper tube with the same strength, is used for the member, the partition can be made lighter than a partition using a cylindrical member made of a round paper tube, and further, the first member and the second member can be connected simply by fitting the second member into the third member, improving the ease of assembly of the partition.

[0006] Patent Document 3 describes a partition comprising a floor panel having a polygonal shape with at least first to third sides and having a groove or hole arranged along each edge of the first to third sides, and at least first to third wall panels having a plate-like shape and a lower end portion fitted into the groove or hole and vertically attached to the edges of the first to third sides of the floor panel, respectively, wherein the floor panel and the wall panels each have a length of a long side that is twice the length of a short side, and two of the short sides of the wall panels are vertically attached to the long side of the floor panel, the floor panels being first to n-th floor panels, the wall panels being first to n-th wall panels, and the first to n-th floor panels being quadrangular in shape with first to fourth sides, and the long side of the first floor panel has a length of the first wall panel and A second wall panel is hung down, a third wall panel is hung down on the short side of the first floor panel, a fourth wall panel and a fifth wall panel are hung down on the long side of the second floor panel, a sixth wall panel is hung down on the short side of the second floor panel, a seventh wall panel is hung down on the short side of the third floor panel, and an eighth wall panel and a ninth wall panel are hung down on the long side of the third floor panel, the first wall panel is connected to the second wall panel, the second wall panel is connected to the third wall panel, and the third wall panel is connected to the fourth wall panel, and similarly the n-2th wall panel is connected to the n-1th wall panel, and the n-1st wall panel is connected to the nth wall panel, and a space is provided between the nth wall panel and the first wall panel and at the side of the nth floor panel where there is no hanging wall panel.

[0007] It is described in Patent Document 3 that the partition disclosed provides privacy protection, is simple, easy and quick to carry and assemble, and is reusable and can be kept clean. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2011-132665 A [Patent Document 2] JP 2020-90886 A [Patent Document 3] Patent No. 6940855 Summary of the Invention [Problem to be solved by the invention]

[0009] It is believed that a partition framework can be easily assembled using the prefabricated partition disclosed in Patent Document 1 and the partition unit disclosed in Patent Document 2. It is also believed that the partition disclosed in Patent Document 3 can be installed relatively easily.

[0010] However, when not in use as a partition, it is difficult to secure a storage space for the components related to the prefabricated partitions and the like disclosed in Patent Documents 1 and 2. Generally, school gymnasiums and the like are used as evacuation sites in the event of a disaster, but it is difficult to secure space to store the components related to the prefabricated partitions and the like under normal circumstances, and they are often stored in warehouses and the like away from the gymnasium. If the evacuation site and storage site are far apart, the components will need to be transported separately when in use, which increases the burden on evacuees.

[0011] The partitions disclosed in Patent Document 3 also have the same problem of storage space, and it is extremely difficult to secure storage space for partitions that are made of large plate materials such as floor and wall panels. Also, in the event of a disaster, it is mostly evacuees who do the assembly work, so there is a demand for partitions that can be easily assembled even by first-timers.

[0012] In view of the above problems, the inventors of the present application conducted extensive research to provide a frame unit that is extremely easy to assemble, allows easy storage space for the component parts, and can be used for purposes other than as a partition frame, and as a result, they arrived at the present invention. [Means for solving the problem]

[0013] In other words, the frame unit of the present invention is composed of a plurality of L-shaped column plate materials and a plurality of I-shaped beam plate materials, wherein the L-shaped column plate materials include a long column portion and a protrusion protruding from one end of the column portion in a direction perpendicular to the longitudinal direction of the column portion, a column-side fitting recess is formed from the center of the end edge of the protrusion opposite the column portion in a direction perpendicular to the longitudinal direction of the column portion, and a mortise hole is formed in the one end of the column portion, and the I-shaped beam plate material includes a long beam portion and a tenon formed on one end edge of the beam portion, and a beam-side fitting recess is formed from the center of the other end edge of the beam portion in the longitudinal direction of the beam portion.

[0014] In addition, in the frame unit of the present invention, the column-side fitting recess is composed of a column-side penetrating recess penetrating both side surfaces of the protrusion and a column-side side groove portion extending from the column-side penetrating recess in the depth direction to one side surface of the protrusion, and the beam-side fitting recess is composed of a beam-side penetrating recess penetrating both side surfaces of the beam portion and a beam-side side groove portion extending from the beam-side penetrating recess in the depth direction to one side surface of the beam portion.

[0015] Furthermore, the frame unit of the present invention is characterized in that one or more locking grooves are provided obliquely upward on the longitudinal end faces of the column portions and on the longitudinal end faces of the beam portions.

[0016] In addition, the frame unit of the present invention is characterized in that the column portions and the beam portions are provided with a plurality of connecting holes.

[0017] Furthermore, the column portion and the beam portion are provided with a plurality of connecting holes. Effect of the Invention

[0018] The frame unit of the present invention is extremely easy to assemble, making it possible to easily form a partition framework in evacuation shelters in the event of a disaster or in event spaces.

[0019] In particular, the frame unit of the present invention is composed of two types of plate materials, L-shaped column plate materials and I-shaped beam plate materials, and does not require any additional connecting members, and can be assembled very easily just by connecting the L-shaped column plate materials and the I-shaped beam plate materials in order. Therefore, even evacuees who are in contact with the frame unit of the present invention for the first time in the event of a disaster can easily assemble it.

[0020] In addition, in the frame unit of the present invention, one or more locking grooves are provided diagonally upward on the longitudinal side edges of the column portion and the longitudinal side edges of the I-beam plate material.By providing a locking material on the wall of a gymnasium, for example, and hooking the locking groove onto this locking material, the L-shaped column plate material and I-shaped beam plate material related to the frame unit of the present invention can be stored on the wall surface, making it easy to secure storage space.

[0021] Furthermore, since the frame unit of the present invention is stored on the wall of a gymnasium or the like that will serve as an evacuation site, transportation work is not required when using the frame unit. Furthermore, by storing the frame units side by side on the wall, the L-shaped column plate material and I-shaped beam plate material of the frame unit of the present invention can also be used as interior materials.

[0022] Furthermore, in the frame unit of the present invention, by providing a plurality of connecting holes in the columns and the I-beam plate material, the L-shaped column plate material and the I-beam plate material of the frame unit of the present invention can be arranged and connected, and it becomes possible to use it for purposes other than as a partition framework, such as a bench or a bed, etc. Therefore, it can be used as a bench under normal circumstances, and when a partition is required, it can be used as a partition framework, and there is no problem of securing storage space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, an embodiment of the frame unit of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing a state in which a partition framework 2 is formed by combining frame units 1 according to one embodiment of the present invention, Fig. 2 is a three-sided view of the partition framework 2 according to this embodiment, and Fig. 3 is a front view showing the components of the frame unit 1 of this embodiment. First, as shown in Figs. 1 and 2, the frame unit 1 according to this embodiment is configured to include a plurality of L-shaped column plate materials 10 and a plurality of I-shaped beam plate materials 20, and the partition framework 2 is formed by combining these plurality of L-shaped column plate materials 10 and the plurality of I-shaped beam plate materials 20.

[0025] As shown in Figure 3(a), the L-shaped column plate material 10 of the frame unit 1 of this embodiment comprises a long column portion 11 and a protrusion portion 12 protruding from one end portion 11a of the column portion 11 in a direction perpendicular to the longitudinal direction of the column portion 11.

[0026] Furthermore, a column-side fitting recess 13 is formed in the center of the edge 12a opposite the column portion 11 of the protrusion 12 provided on the L-shaped column plate material 10, in a direction perpendicular to the longitudinal direction of the column portion 11 of the L-shaped column plate material 10.

[0027] Here, the column-side fitting recess 13 according to the L-shaped column plate 10 of this embodiment is characterized by being composed of a column-side through recess 13a penetrating both side surfaces of the protruding portion 12, and a column-side side groove portion 13b extending from the column-side through recess 13a in the depth direction, in other words, from the end edge 12a side of the protruding portion 12 toward the column portion 11, to one side surface 12b side of the protruding portion 12. The column-side fitting recess 13 may be composed of only the column-side through recess 13a penetrating both side surfaces of the protruding portion 12, but by being composed of the column-side through recess 13a and the column-side side groove portion 13b as in this embodiment, the fitting state with the beam-side fitting recess 23 described later can be made stronger.

[0028] Further, a mortise 14 is formed in one end 11a of the column portion 11 of the L-shaped column plate material 10, that is, in the end 11a of the column portion 11 on the side having the protruding portion 12.

[0029] Next, as shown in Fig. 3(b), the I-beam plate material 20 relating to the frame unit 1 of this embodiment has a long beam portion 21 and a tenon 22 formed at one end edge 21a of the beam portion 21. Note that, although a two-sided flat tenon is used as the tenon 22 in this embodiment, the form of the tenon 22 is not particularly limited, and the mortise hole 14 formed at the end portion 11a of the L-shaped column plate material 10 is also formed according to the form of the tenon 22.

[0030] Also, the I-beam plate material 20 is characterized in that a beam-side fitting recess 23 is formed in the longitudinal direction of the beam portion 21 from the center of the other end edge 21b of the beam portion 21.

[0031] Here, the beam-side fitting recess 23 of the I-beam plate material 20 of this embodiment is characterized by being composed of a beam-side through recess 23a penetrating both side surfaces of the beam portion 21, and a beam-side side groove 23b extending from the beam-side through recess 23a in the depth direction, in other words, from the other end edge 21b of the beam portion 21 to the one end edge 21a, toward one side surface 21c of the beam portion 21. The beam-side fitting recess 23 may be composed of only the beam-side through recess 23a penetrating both side surfaces of the beam portion 21, but by being composed of the beam-side through recess 23a and the beam-side side groove 23b as in this embodiment, the fitting state with the column-side fitting recess 13 described above can be made stronger.

[0032] The frame unit 1 of this embodiment is configured to include the above-mentioned L-shaped column plate material 10 and I-shaped beam plate material 20, and by combining these alternately, a partition frame 2 can be formed very easily. Specifically, as shown in Figs. 4 to 6, a beam-side fitting recess 23 formed on the other end edge 21b of the beam portion 21 related to the I-shaped beam plate material 20 is inserted into a column-side fitting recess 13 formed on a protruding portion 12 of the L-shaped column plate material 10. Also, a tenon 22 formed on one end edge 21a of the beam portion 21 related to the other I-shaped beam plate material 20 is inserted into a mortise hole 14 formed in the L-shaped column plate material 10.

[0033] Furthermore, the beam-side fitting recess 23 formed on the other end edge 21b of the beam portion 21 of this other I-beam plate material 20 is inserted into the column-side fitting recess 13 formed on the protruding portion 12 of the other L-shaped column plate material 10. In this manner, the L-shaped column plate materials 10 and the I-beam plate materials 20 are alternately connected in sequence, whereby the partition framework 2 can be assembled very easily.

[0034] As described above, the frame unit 1 of this embodiment is extremely easy to assemble, and therefore the partition framework 2 can be easily formed in an evacuation shelter in the event of a disaster or in an event space.

[0035] In particular, the frame unit 1 of this embodiment is composed of only two types of plate materials, the L-shaped column plate material 10 and the I-shaped beam plate material 20, and does not require any additional connecting members or metal fittings, and the partition framework 2 can be assembled very easily just by sequentially connecting the L-shaped column plate materials 10 and the I-shaped beam plate materials 20. Therefore, in the event of a disaster, even evacuees who are in contact with the frame unit 1 of this embodiment for the first time can easily assemble it.

[0036] Furthermore, in this embodiment, for example, if the column side fitting recess 13 of the L-shaped column plate material 10 is configured only with the column side penetrating recess 13a, and the beam side fitting recess 23 of the I-shaped beam plate material 20 is configured only with the beam side penetrating recess 23a, the L-shaped column plate material 10 and the I-shaped beam plate material 20 can be connected alternately very easily, and the partition framework 2 can be easily assembled.

[0037] However, further, by configuring the column side fitting recess 13 of the L-shaped column plate material 10 that constitutes the frame unit 1 of this embodiment with the column side penetrating recess 13a and the column side groove portion 13b, and configuring the beam side fitting recess 23 of the I-shaped beam plate material 20 with the beam side penetrating recess 23a and the beam side groove portion 23b, a larger joint area can be secured when the column side fitting recess 13 of the L-shaped column plate material 10 and the beam side fitting recess 23 of the I-shaped beam plate material 20 are fitted together, thereby making the fitting state even stronger, preventing shaking of the framework 2 and improving the strength of the framework 2.

[0038] In addition, by configuring the column-side fitting recess 13 and the beam-side fitting recess 23 of this embodiment as described above, when fitting the column-side through recess 13a of the column-side fitting recess 13 and the beam-side through recess 23a of the beam-side fitting recess 23, if the upper and lower surfaces of the I-shaped beam plate material are mistaken, they cannot be fitted together, so there is no risk of a mismatch. That is, as shown in Figures 5 and 6, the column-side fitting recess 13 and the beam-side fitting recess 23 cannot be fitted together unless the beam-side side groove portion 23b of the beam-side fitting recess 23 of the I-shaped beam plate material 20 is inserted with the beam-side side groove portion 23b facing up into the column-side fitting recess 13 of the L-shaped column plate material 10, so there is no risk of a mismatch and the strength of the framework 2 is improved by maintaining a strong fitting state.

[0039] The frame unit 1 according to one embodiment of the present invention has been described in detail above. It is preferable that the L-shaped column plate material 10 and the I-shaped beam plate material 20 constituting the frame unit 1 of this embodiment are provided with a locking groove 15 as shown in Fig. 3. Specifically, as shown in Fig. 3(a), the locking groove 15 is disposed obliquely upward on the longitudinal end face 11b of the column portion 11 of the L-shaped column plate material 10. Similarly, as shown in Fig. 3(b), the locking groove 15 is disposed obliquely upward on the longitudinal end face 21d of the beam portion 21 of the I-shaped beam plate material 20.

[0040] In this way, one or more locking grooves 15 are arranged in the L-shaped column plate material 10 and the I-shaped beam plate material 20 that constitute the frame unit 1 of this embodiment, so that, for example, as shown in Figure 7, a locking material 34 can be installed in advance on a wall surface W of a gymnasium or the like, and the locking grooves 15 provided on the L-shaped column plate material 10 and the I-shaped beam plate material 20 can be hooked onto this locking material 34, thereby allowing the L-shaped column plate material 10 and the I-shaped beam plate material 20 relating to the frame unit 1 of this embodiment to be hooked onto the wall surface W for storage, making it easy to secure storage space.

[0041] In addition, by storing the frame unit 1 of this embodiment using the wall surface W of a gymnasium or the like that serves as an evacuation site, there is no need to transport the L-shaped column plate materials 10 and the I-shaped beam plate materials 20 when using the frame unit 1. Furthermore, by storing them side by side on the wall surface W, the L-shaped column plate materials 10 and the I-shaped beam plate materials 20 related to the frame unit 1 of this embodiment can also be used as interior materials 5.

[0042] In addition, it is preferable that the column portion 11 of the L-shaped column plate material 10 and the beam portion 21 of the I-shaped beam plate material 20 constituting the frame unit 1 of this embodiment are provided with a plurality of connection holes 16 as shown in Fig. 3. In this way, by forming a plurality of connection holes 16 in the column portion 11 of the L-shaped column plate material 10 and the beam portion 21 of the I-shaped beam plate material 20, for example, as shown in Fig. 8, the bench 3 can be formed by alternately arranging the plurality of L-shaped column plate materials 10 and the plurality of I-shaped beam plate materials 20 of the frame unit 1 of this embodiment, and connecting the plurality of L-shaped column plate materials 10 and the plurality of I-shaped beam plate materials 20 by screwing nuts 32 to the long bolts 31 inserted into the respective connection holes 16. Therefore, the frame unit 1 of this embodiment is normally used as the bench 3, and when a partition is required, the bench 3 can be disassembled and used as the framework 2 for the partition, and there is no problem such as securing a storage space.

[0043] Furthermore, as shown in Figure 9, for example, by arranging a plurality of L-shaped column plate materials 10 and a plurality of I-shaped beam plate materials 20 of the frame unit 1 of this embodiment alternately and arranging a plate member 33 on the upper surface connected by long bolts 31 and nuts 32, the frame unit 1 of this embodiment can also be used as a bed 4.

[0044] Although the embodiment of the frame unit of the present invention has been described in detail above, the above embodiment should not be interpreted as substantially limiting the technical idea of ​​the present invention. For example, the materials of the L-shaped column plate material and I-shaped beam plate material constituting the frame unit of the present invention are not particularly limited, and wood, plastic, cardboard, etc. can be used.

[0045] Furthermore, when wood is used, particularly by using boards that are laminated and glued together so that the grain direction of the sawn boards is perpendicular, it is possible to provide L-shaped column boards and I-shaped beam boards that are extremely strong and to make effective use of thinned wood.

[0046] Furthermore, with respect to a bench formed of L-shaped column plate materials and I-shaped beam plate materials constituting the frame unit of the present invention, as in the bench 3a shown in Fig. 10, a foot member 40 may be attached to the protrusion 12 of the L-shaped column plate material 10. As shown in Figs. 11(a) to (c), a plurality of foot fitting recesses 43 are formed in the foot member 40. The foot fitting recesses 43 are also composed of a foot through recess 43a penetrating from the front surface 41 to the back surface 42 of the foot member 40, and a foot side groove portion 43b extending from the foot through recess 43a in the depth direction (the formation direction of the foot fitting recess 43) toward the front surface 41 side of the foot member 40.

[0047] Therefore, by connecting a plurality of L-shaped column plate materials 10 and a plurality of I-shaped beam plate materials 20 and by fitting the foot fitting recess 43 of the foot member 40 into the column side fitting recess 13 of the L-shaped column plate material 10, a bench 3a to which the foot member 40 is firmly joined can be obtained. Also, by attaching the foot member 40, the edge 12a of the protrusion 12 of the L-shaped column plate material 10 can be protected. The number of foot fitting recesses 43 formed in the foot member 40 is not particularly limited, and at least two foot members are necessary to form the bench 3a with one set of frame units 1, and four foot members are necessary to form the bench with two sets of frame units 1.

[0048] Furthermore, in the above-mentioned embodiment, in order to form a partition frame, it is preferable to set the overall length of the L-shaped column plate material and I-shaped beam plate material of the frame unit of the present invention to about 2 m, but by setting the overall length of the L-shaped column plate material and I-shaped beam plate material of the frame unit of the present invention to about 0.5 to 1 m, for example, the frame unit of the present invention can be used as a toy for children, and a bench or bed for children can be formed. The present invention can be implemented with appropriate improvements, changes, or additions based on the ingenuity and ingenuity of those skilled in the art, without departing from the gist of the present invention.
