Description

  The present invention relates to a cardboard folding building.

  In disaster-stricken areas, beaches, construction sites, and entertainment venues, temporary buildings may be installed as temporary facilities for use for a certain period of time. Such temporary buildings include toilets, changing rooms, shower rooms, and warehouses. As a foldable building applied to an assembly-type toilet, a structure in which a plurality of private room spaces are adjacent to each other is known (for example, see Patent Document 1). This foldable building includes a plurality of flat plate-like walls that are connected to each other on one side. The plurality of wall bodies are radially expanded from the folded state where they overlap each other around the connected one side, thereby defining a private room space having a substantially triangular shape in plan view between the pair of wall bodies.

Japanese Patent No. 4117321

  In addition to being easy to assemble, such a conventional foldable building is assumed to be used outdoors or used as a shower room or the like, so it requires water resistance as well as strength. did. For this reason, the conventional foldable building needs to use a water-resistant material such as a plastic material as a component, and therefore, the manufacturing cost tends to increase and the weight tends to increase. In addition, a large amount of costs may be incurred in the processing for ending the useful life of the building.

  On the other hand, it is assumed that an unspecified number of uninformed people are forced to live in indoor spaces such as gymnasiums as evacuation sites during disasters. Many people living there are said to suffer more mental pain than physical pain because they are forced to live without privacy at disaster sites for a long time. Therefore, for example, when an attempt is made to use a conventional outdoor foldable building as a space for ensuring privacy during acts such as toilets, breastfeeding, use of mobile phones, and changing clothes, multiple units are used because they are expensive. In addition to being difficult to introduce, the heavy weight makes it difficult to handle during assembly and damages the gym floor, etc. during installation. On the other hand, if a building is simply made of corrugated cardboard with reduced material costs and weight, strength will be reduced.

  An object of the present invention is to provide a corrugated cardboard foldable building capable of appropriately ensuring strength with a simple structure.

  The corrugated cardboard folding building of the present invention includes a plurality of side walls constituting a private room space, and a door wall connected to one of the plurality of side walls so as to be openable and closable, and faces the side wall to which the door wall is connected. The side wall (hereinafter referred to as the first side wall) is configured to have a door stop portion that is bent into a columnar shape at a door stop position of the door wall.

  Since the door contact is the part where the door wall contacts each time the door is opened and closed, it is particularly required to ensure strength when it is made of cardboard. In this respect, according to the present invention, since the door stop portion is configured as described above, the strength of the door stop portion can be improved, and the strength of the building at the time of opening and closing the door wall can be improved. . Moreover, since the door stop part is comprised by bending, it can be set as a simple structure.

  In this case, the door stop is preferably bent into a triangular prism shape from one end of the first side wall. By doing so, it is simpler and the strength can be further improved as compared with, for example, a quadrangular prism shape.

  In this case, the door stop portion extends from one end of the first side wall and is first from one end of the first wall body extension portion and the first wall body extension portion positioned so as to block a part of the entrance / exit of the private room space. A second wall extension extending toward the side wall; a third wall extension extending from one end of the second wall extension along the first side wall and fixed to the first side wall; It is preferable to have.

  In this case, the height of the third wall body extension is preferably shorter than the height of the first and second wall body extensions. Compared to the case where the three wall body extension portions have the same height, the fixing operation of the third wall body extension portion with respect to the first side wall can be simplified.

  In these cases, the door wall has a lock portion for fixing the door wall in a closed state, and at least one of the first and second wall body extension portions is a lock for receiving the lock portion. It is preferable that a groove is formed. According to this configuration, the privacy of the building user can be more effectively protected.

  In this case, the folding building of the present invention preferably has at least one of a shelf, a floor, and a roof connected to the plurality of side walls. According to this configuration, the strength of the building can be further improved.

  In this case, it is preferable that at least one of the upper surface and the front surface of the roof is provided with a window formed by cutting a cardboard constituting the roof. Thereby, it is possible to provide a building capable of daylighting or ventilation with a simple configuration as required by the user.

  In this case, it is preferable that the floor has a stepped shape formed by folding a part of the corrugated cardboard constituting the floor downward on the entrance / exit side of the private room space. According to this configuration, it is possible to reinforce a portion that is frequently stepped on by a person and not to expose the cross section of the cardboard.

  According to the folding building of the present invention, it is possible to appropriately ensure strength and privacy with a simple structure.

  Hereinafter, a foldable building according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a first embodiment of a corrugated cardboard folding building 1.
The cardboard folding building 1 can be assembled from a folded state (not shown) as shown in FIG. 1 to form a private room space 2 (hereinafter referred to as a private room state). Here, referring to the building 1 in FIG. 1, a folding shelf 5 for general use, a floor 6 in contact with the installation floor, and a roof 7 on the ceiling are provided in the private space 2. As will be described later, these components function as one of the individual chamber holding means. Each of the shelf body 5, the floor body 6, and the roof body 7 may be used together with the building main body 3 at the same time, and any two or one of the constituent bodies is used according to the required strength and situation. Just fine.

  The building main body 3 has three wall bodies 3a, 3b, 3c as a plurality of side walls for constituting the private room space 2. The three wall bodies 3a, 3b, 3c are made of a single cardboard, and are bent into a U-shape as a whole to form a single chamber state. A door body 4 is connected to one end portion of the wall body 3a, and the door 2 can be opened and closed by rotating the door body 4 in the front-rear direction. In addition, a columnar door stop 10 is formed at the door stop position of the door 4, that is, at one end of the wall 3 c facing the wall 3 a. The number of side walls constituting the private room space 2 differs depending on the planar shape of the private room space 2 (for example, a quadrangle as in the present embodiment, and a trapezoid and a triangle are conceivable). In the case of 2, there are two side walls.

FIG. 2 is a plan view around the door stop 10 of FIG. Moreover, FIG. 3 is a figure which shows the state which expand | deployed the building main body 3. FIG.
1 and 3, the wall body 3a and the wall body 3b are bent along the fold line 31 so as to form a right angle, and similarly, the fold line 32 so that the wall body 3b and the wall body 3c form a right angle. The private space 2 is formed. In this state, the wall 3a and the wall 3c face each other in parallel with the private chamber space 2 interposed therebetween.

  As shown in FIG. 1, for example, a shelf 5 as a private room holding means can be used in order to maintain the private room state firmly. Here, the shelf body 5 is a shelf body formed on the shelf board 5 so as to correspond to the wall body connection holes 8a to 8d formed in the wall bodies 3a to 3c and the wall body connection holes 8a to 8d in an assembled state. By connecting a connection hole (not shown) with the connection tool 9, it is fixed over wall body 3a-3c. The connection tool 9 used here is not particularly limited as long as both members can be fixed.

  Referring to FIG. 3, the open end portion of the wall body 3 c is extended by the wall body extension portions 3 d, 3 e, and 3 f constituting the door stop portion 10 as compared with the open end portion of the wall body 3 a. . Folds 33 to 35 are formed at the boundary between the wall 3c and the wall extension 3d and the boundary between the wall extensions 3d to 3f. The wall extension 3f is shorter in the height direction of the building 1 than the wall extensions 3d and 3e.

  Here, as shown in FIG. 2, in order to configure the door stop 10 in the assembled state, the wall extension 3d in the unfolded state is bent 90 degrees along the fold line 33 toward the wall 3a. The extension 3e is bent along the fold line 34 toward the inner wall of the wall 3c. Further, the wall extension 3f is bent at the crease 35 so as to be along the inner wall of the wall 3c.
