Description

[Technical Field]

[0001] The present invention relates to a simple house that provides a small room surrounded by a roof and a plurality of wall panels and is used, for example, as an office, temporary store, warehouse, lodging, etc. at a construction site, and more recently as a residence, and in particular to a simple house that is small enough to be transported on the back of a truck, and in which all or some of the wall panels used can be replaced and rearranged. [Background technology]

[0002] A known example of this type of simple house is disclosed in Japanese Patent Laid-Open Publication No. 2015-101896 (Patent Document 1). As shown in Fig. 9, this simple house Ha includes a floor 101 having a rectangular metal floor frame 100, and a roof 103 having a rectangular metal roof frame 102 corresponding to and parallel to the floor frame 100. Six metal supports 104 are installed between the floor frame 100 and the roof frame 102, with four of these supports 104 installed between the four corners of the floor frame 100 and the four corners of the roof frame 102, and the remaining two are installed between a pair of opposing long sides, in the center between the corners. This provides six pairs of adjacent supports 104, and a wall panel 105 is installed on each pair of adjacent supports 104. Various types of wall panels 105 are available, such as those formed entirely of wall, those with doors, and those with windows.

[0003] In six sets of adjacent pairs of posts 104, the spacing between adjacent pairs of posts 104 is the same, making it possible to interchange the wall panels 105 attached to these. Specifically, mortise holes 106 are formed in the longitudinal direction on the opposing sides of adjacent posts 104, and tenons 107 are formed on both side edges of each wall panel 105, which slide from above to engage with mortise holes 106.

[0004] This conventional simple house Ha is assembled, for example, in a factory. To do this, the posts 104 are erected on the floor frame 100 of the floor 101. Then, the wall panels 105 are lifted by a crane or similar device and moved to the desired position. The tenons 107 are then inserted into the tenon holes 106 of the posts 104 from above and slid to engage, attaching the panels between the posts 104. Finally, the roof 103 is lifted by a crane or similar device, and the roof frame 102 is attached to the posts 104. The simple house Ha assembled in this manner is then loaded onto the back of a truck, transported to the location where it will be used, and installed. Of course, it can also be assembled on the installation site. This allows the simple house Ha to be used as an office, temporary store, warehouse, lodging, or other purpose at a construction site.

[0005] Furthermore, in this simple house Ha, there may be cases where the positions of the doors or windows need to be changed, for example, at the installation site or when transporting it by truck for use at another location. In this case, first, the roof 103 is lifted and removed using a crane or similar device. Then, in the reverse order of assembly, the necessary wall panels 105 are lifted using a crane or similar device and their tenons 107 are slid into the mortise holes 106 of the posts 104 to remove them. Then, as described above, each removed wall panel 105 is lifted using a crane or similar device and moved to the desired position, and the tenons 107 are inserted into the mortise holes 106 of the posts 104 from above and slid to engage, thereby attaching them between the posts 104. Finally, the roof 103 is lifted again using a crane or similar device, and the roof frame 102 is attached to the posts 104. This allows the simple house to be used with the positions of the doors and windows adjusted to suit the conditions of the installation site. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-101896 Summary of the Invention [Problem to be solved by the invention]

[0007] In this conventional simple house Ha, rearranging the wall panels 105 and changing the positions of the doors and windows requires lifting and removing the roof 103 with a crane or other device, and then lifting and removing the necessary wall panels 105, again with a crane or other device, making the process extremely cumbersome. Furthermore, when assembling each removed wall panel 105, the roof 103 must be lifted and moved to the desired position with a crane or other device, and finally the roof 103 must be lifted and attached to the supports 104 with a crane or other device, making the process extremely cumbersome. In other words, in the conventional simple house Ha, the roof 103 and the wall panels 105 must be attached and removed with a crane or other device, resulting in inefficient replacement of the wall panels 105. Furthermore, drilling mortise holes 106 in the supports 104 and forming tenons 107 in the wall panels 105 requires tedious processing, a complex structure, and high manufacturing costs.

[0008] To provide a simple house made in view of the above points, which can easily replace wall panels without complicating the structure and removing the roof, thereby improving the efficiency of the work of replacing wall panels. [Means for solving the problem]

[0009] In order to achieve the above object, the simple house of the present invention comprises a floor having a rectangular metal floor frame, and a roof having a rectangular metal roof frame that corresponds to and is arranged parallel to the floor frame, and four or more metal supports are provided between the floor frame and the roof frame, and the supports are provided between at least four corners of the floor frame and four corners of the roof frame, and at least four sets of adjacent pairs of supports are provided, and wall panels are provided on the sets of adjacent pairs of supports, and a plurality of sets of supports are provided so that the spacing between the adjacent pairs of supports is the same, and the wall panels provided on the sets of supports so that the spacing between the adjacent pairs of supports is the same are interchangeable. The wall panel is configured to include a rectangular metal wall frame that is loosely inserted into a corresponding wall space formed by the floor frame, roof frame, and a pair of adjacent supports, and frame-shaped metal flanges are extended from the wall frame to abut on the outer surfaces of the floor frame, roof frame, and a pair of adjacent supports, and a plurality of bolts are erected at predetermined intervals on the outer surfaces of at least a pair of supports that form the wall space where the flanges abut, and bolt insertion holes corresponding to the bolts are formed in the flanges, and the wall panel is fixed to the corresponding wall space by screwing nuts onto the bolts to press the flanges against the supports. Various types of wall panels are available, such as those formed entirely of wall, those with doors, and those with windows.

[0010] As a result, the assembly of the simple house of the present invention can be carried out, for example, in a factory. During this process, the support columns are erected on the floor frame, and then the roof is lifted and attached to the support columns using a crane or similar device. Next, each wall panel is manually moved to the desired position by a worker. The bolts of the support columns are inserted into the bolt holes in the flanges of the wall panel, loosely supporting the wall frame in the corresponding wall space. Nuts are then screwed onto each bolt and tightened, pressing the flanges against the support columns. This secures the wall panel to the corresponding wall space. In this manner, the wall panels are sequentially attached to the wall space. The assembled simple house can be transported to the intended location, for example, on the back of a truck, and then installed. Of course, it can also be assembled on the installation site. This allows the simple house to be used as an office, temporary store, warehouse, dormitory, or other facility at a construction site.

[0011] Furthermore, in this simple house, for example, when the position of a door or window needs to be changed, either at the installation site or when transporting it by truck for use elsewhere, the position of the door or window may need to be changed. In this case, the necessary wall panel is simply unscrewed from the bolt by loosening the nuts, in the reverse order of assembly. Then, a worker manually holds the wall panel and removes the bolt holes in the wall panel flange from the bolts on the support posts, moving it to the desired position. Then, as described above, the bolts on the support posts are inserted into the bolt holes in the wall panel flange, loosely supporting the wall frame in the corresponding wall space. Then, nuts are screwed onto each bolt and tightened, pressing the flange against the support posts. This secures the wall panel to the corresponding wall space. In this case, wall panels can be replaced without removing the roof, simply by removing and reinstalling the nuts. This eliminates the need to lift the roof with a crane or other device each time, as in the conventional method, thereby improving the efficiency of wall panel replacement work.

[0012] In addition, the wall panels are removed facing outward and attached from the outside, rather than inward, so they do not need to be lifted up as in the past, making them easy to install and remove, which also improves workability.Furthermore, since the wall panels are fastened only with nuts, the structure can be simplified and costs can be reduced.

[0013]

[0006] If necessary, the bolts may be installed only on the support columns, and the bolt insertion holes may be formed only in the flange portions that abut against the support columns. It is also possible to install bolts on all of the floor frame, roof frame, and pair of adjacent support columns that make up the wall space, and form bolt insertion holes corresponding to these bolts around the entire circumference of the flange of the wall panel. However, by installing bolts only on the support columns and forming bolt insertion holes only in the flange portions that abut against the support columns, the structure is simplified and fewer nuts are required for fastening, which makes it easier to replace the wall panels and further improves the efficiency of the replacement work. In this case, the wall frame is loosely inserted into the wall space, and the flange abuts against the floor frame, roof frame, and pair of adjacent support columns, so the support of the wall panel is not impaired.

[0014] In this configuration, it is effective to interpose a sheet-like packing between the support and the flange, which can improve sealing performance.

[0015] Furthermore, if necessary, a configuration may be provided in which a plurality of groups of columns each having the same spacing between adjacent pairs of columns are provided, each group having different spacing dimensions between the columns.By providing a plurality of groups with different spacing dimensions between the columns, versatility can be improved accordingly.

[0016] Furthermore, if necessary, the support columns installed between the corners of the floor frame and the corners of the roof frame may be configured to include a main support column installed between the corners and a sub-support column installed adjacent to or connected to the main support column, with the flanges of the wall panel abutting against the sub-support column and the bolts being erected on the sub-support column. This configuration provides high strength at the corners, enabling stable support with a simple structure. In this configuration, at the corners of the floor frame and the roof frame, the members constituting the floor frame and the roof frame extend, bending 90° around the main support column. The sub-support column may be installed between the members on either one or the other side of the extension, or between both the members on either side of the extension. That is, there may be one or two sub-support columns. Having two sub-support columns provides greater strength.

[0017] In this case, it is effective to attach an inner corner cover, which has an L-shaped cross section and covers the wall frame side of the support column and the wall panel attached to the support column, to the inside of the support column. Covering the inner corner with an inner corner cover improves the appearance quality of the inner corner with a simple structure. In particular, when there is only one support column, the wall panel gets in the way and it is difficult to install an inner corner cover. However, by providing a secondary support column, the inner corner cover can be attached to the secondary support column, reliably covering the inner corner and improving the appearance quality.

[0018] Furthermore, if necessary, when another support column is installed between adjacent support columns that are installed between the corners of the floor frame and the corners of the roof frame, an inner intermediate cover with an I-shaped cross section is attached to the inner surface of the other support column, covering the inner surface of the other support column and the wall frame side of the wall panel installed on the other support column. Covering the other support column with the inner intermediate cover, in combination with the inner corner cover, improves the appearance quality with a simple structure. In particular, the inner intermediate cover protrudes inward by its thickness, but this is visually recognized as if a column were there, further improving the appearance quality.

[0019] Furthermore, if necessary, outer corner covers with an L-shaped cross section are attached to the outer surfaces of the four pillars that are installed between the four corners of the floor frame and the four corners of the roof frame, at the exposed longitudinal corners that are not reached by the flanges of the wall panels. Covering the outside of the pillars with outer corner covers improves the appearance quality of the outside of the pillars at the corners, despite the simple structure. [Effects of the Invention]

[0020] As described above, with the simple house of the present invention, there may be occasions when the position of a door or window needs to be changed, for example, at the installation site or when the house is transported by truck and used elsewhere. However, wall panels can be replaced without removing the roof by simply removing and installing nuts. This eliminates the need to lift the roof up each time using a crane, as in the conventional method, thereby improving the efficiency of wall panel replacement. Furthermore, since the wall panels are removed from the outside rather than the inside and installed from the outside, they are easily installed and removed without the need to lift them up as in the conventional method, which also improves workability. Furthermore, since the wall panels are fastened simply with nuts, the structure can be simplified and costs can be reduced. [Brief explanation of the drawings]

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A simple house according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings. A simple house H according to an embodiment of the present invention, as shown in Figures 1 to 7, includes a floor 2 having a rectangular metal floor frame 1, and a roof 4 having a rectangular metal roof frame 3 that corresponds to and is parallel to the floor frame 1. The floor frame 1 is formed by welding a rectangular closed-section iron rod to a main support 11 of a support column 10, which is made of iron rod material with a similar rectangular closed cross section (described below). The rod material and a portion of the main support column 11 to which the rod material is welded form a rectangular frame. Beams 1a (Figure 4) made of similar rod material are installed on the floor frame 1, and a floor 2 is formed by laying, for example, wooden flooring material 5 on top of the beams. The underside of the floor frame 1 is supported by a metal base 6, such as iron.

[0023] The roof frame 3 is formed into a rectangular frame shape by welding together steel bars, also having a rectangular closed cross section. As shown in Figure 3, an upper frame 7, similar to the roof frame 3, is positioned at an angle above the roof frame 3 and is supported by an appropriate number of support members (not shown) made of similar bars. Beams (not shown) made of similar bars are erected on the upper frame 7, and the roof 4 is formed by covering the roof frame 3, upper frame 7, beams, and support members with an appropriate roofing material 8. The outer surface of the roof frame 3 is exposed so that flanges 21 of wall panels 20, described below, can abut against it.

[0024] Furthermore, the simple house H according to the embodiment has four or more metal pillars 10 installed between the floor frame 1 and the roof frame 3, and the pillars 10 are installed between at least four corners of the floor frame 1 and four corners of the roof frame 3, with at least four pairs of adjacent pillars 10. In the embodiment, the pillars 10 are made of iron bars with a rectangular closed cross section, and the four pillars 10 are installed by welding between the four corners of the floor frame 1 and the four corners of the roof frame 3, respectively, with two pillars 10 installed by welding on one side of the long sides along the longitudinal direction of the floor frame 1 and the roof frame 3, with a required interval between the pillars 10 at the corners, and the other two pillars 10 installed by welding on the other side of the long sides along the longitudinal direction of the floor frame 1 and the roof frame 3, with a required interval between the pillars 10 at the corners.

[0025] The pillars 10 erected between the corners of the floor frame 1 and the corners of the roof frame 3 are comprised of a main pillar 11 erected between the corners and a sub-pillar 12 joined to or erected adjacent to the main pillar 11. The lower end of the lower part of the main pillar 11 extends toward the base 6, and the rods that make up the floor frame 1 are welded to the lower part, and the floor frame 1 is formed into a frame shape by these rods and parts of the main pillar 11 to which they are welded. At the corners of the floor frame 1 and the corners of the roof frame 3, the rods that make up the floor frame 1 and the roof frame 3 extend, bent 90 degrees around the main pillar 11, and the sub-pillars 12 are erected by welding to these extending rods that make up the short sides of the floor frame 1 and the roof frame 3.

[0026] At least four pairs of adjacent columns 10 are provided. In this embodiment, eight pairs are provided. Wall panels 20 are provided on all or some (in this embodiment, all) of these pairs of adjacent columns 10. Among these pairs of adjacent columns 10, multiple pairs of columns 10 are provided with the same spacing between the adjacent pairs of columns 10, and the wall panels 20 provided on pairs of columns 10 with the same spacing between the adjacent pairs of columns 10 are interchangeable.

[0027] More specifically, in this embodiment, as shown in FIG. 4, multiple groups (two in this embodiment) are provided, each group consisting of a plurality of sets of columns 10 with the same spacing between adjacent pairs of columns 10, but with different spacing dimensions between the columns 10. One group includes six sets of columns 10 Ga, each with a spacing La between adjacent pairs of columns 10. This group includes a set of columns 10 at both longitudinal ends and a set of four columns 10 at one longitudinal end. The other group includes two sets of columns 10 Gb, each with a spacing Lb between adjacent pairs of columns 10. This other group includes two sets of columns 10 at the other longitudinal end. Six wall panels 20 are provided for one group (set of columns 10 Ga), and these are mutually interchangeable. Two wall panels 20 are provided for the other group (set of columns 10 Gb), and these are mutually interchangeable.

[0028] As shown in Figures 1, 2 and 5, the basic configuration of each wall panel 20 comprises a rectangular metal wall frame 21 loosely inserted into a corresponding wall space E formed by a floor frame 1, a roof frame 3 and a pair of adjacent columns 10. This wall frame 21 has a frame-shaped metal flange 22 extending therefrom that abuts against the outer surfaces of the floor frame 1, the roof frame 3 and a pair of adjacent columns 10. In the wall space E formed by the sub-columns 12 that are the columns 10 at the corners, the flange 22 abuts against the outer surfaces of the sub-columns 12.

[0029] Furthermore, a plurality of bolts 23 are provided at predetermined intervals on the outer surfaces of at least one pair of columns 10 that constitute the wall space E, where the flanges 22 of the columns 10 abut. In the columns 10 at the corners, bolts 23 are provided on the outer surfaces of the main columns 11 and the sub-columns 12, where the flanges 22 of the columns 10 abut. Meanwhile, bolt insertion holes 24 corresponding to the bolts 23 are formed in the flanges 22, and the wall panel 20 is fixed to the corresponding wall space E by screwing nuts 25 onto the bolts 23 to press the flanges 22 against the columns 10. In this embodiment, the bolts 23 are provided only on the columns 10, and are not provided on the floor frame 1 or the roof frame 3. Furthermore, the bolt insertion holes 24 are formed only on the portions of the flanges 22 that abut against the columns 10, and are not provided on the floor frame 1 or the roof frame 3. A sheet-like packing 26 is interposed between the column 10 and the flange 22.

[0030] As shown in Figure 1, six wall panels 20 are provided for one group (set Ga of supports 10), of which three wall panels 20(A) have boards attached to the front and back of the wall frame 21, making the entire surface a wall. One of these wall panels, 20(B), has a pair of sliding doors attached to the wall frame 21. Another of these wall panels, 20(C), is half covered with boards and half has a hinged door. Another of these wall panels, 20(D), has boards attached to the lower half and a window frame with a sliding door window attached to the upper half.

[0031] Two wall panels 20 are provided for the other group (set Gb of supports 10), and one wall panel 20(E) is formed entirely of wall with boards attached to the front and back of the wall frame 21. The other wall panel 20(F) has boards attached to the front and back of the wall frame 21 and has a ventilation window above it.

[0032] 6, in the simple house H according to the embodiment, inner corner covers 30 each having an L-shaped cross section are attached to the inside of the support posts 10 at the corners to cover the support posts 10 and the wall frame 21 side of the wall panels 20 attached to the support posts 10. These inner corner covers 30 are fixed to the sub-support posts 12 with screws or adhesive. In particular, when there is only one support post 10, the wall panels 20 get in the way and it is difficult to attach the inner corner covers 30; however, since the sub-support post 12 is provided, the inner corner covers 30 can be attached to the sub-support post 12.

[0033] Furthermore, in the support columns 10 provided between adjacent support columns 10 that are erected between the corners of the floor frame 1 and the roof frame 3, an inner intermediate cover 31 having an I-shaped cross section is attached to the inner surface of the support column 10, covering the inner surface of the support column 10 and the wall frame 21 side of the wall panel 20 provided on the support column 10. The inner intermediate cover 31 is fixed to the support column 10 with screws or adhesive.

[0034] Furthermore, outer corner covers 32, each having an L-shaped cross section, are attached to the outer surfaces of the four pillars 10 installed between the four corners of the floor frame 1 and the four corners of the roof frame 3, at exposed longitudinal corners not reached by the flanges 22 of the wall panels 20. The outer corner covers 32 are fixed to the pillars 10 with screws or adhesive. Note that the inner corner covers 30, inner middle cover 31, and outer corner covers 32 are not shown in Figures 1, 2, 4, and 7. In Figure 3, reference numeral 40 denotes a hook that protrudes above the roof 4 and is used to lift the entire simple house H with a crane.

[0035] Therefore, the simple house H according to the embodiment is assembled, for example, in a factory. For example, the columns 10 are welded to the floor frame 1 of the floor 2, and then the roof 4 is lifted using a crane or similar device and attached to the columns 10 by welding. Next, a worker manually moves each wall panel 20 to the desired position. The bolts 23 of the columns 10 are inserted into the bolt holes 24 of the flanges 22 of the wall panel 20, and the wall frame 21 is supported by loosely inserting it into the corresponding wall space E. A gasket 26 is interposed between the flanges 22 and the columns 10. Then, nuts 25 are screwed onto each bolt 23 and tightened to press the flanges 22 against the columns 10. This secures the wall panel 20 to the corresponding wall space E. In this manner, the wall panels 20 are sequentially attached to the wall space E. Then, the inner corner covers 30, inner intermediate covers 31, and outer corner covers 32 are attached. Interior and exterior finishing is also performed as appropriate.

[0036] The simple house H assembled in this manner is transported to the intended location, for example, on the back of a truck, and then installed. Of course, it can also be assembled at the intended location. This allows the simple house H to be used as an office, temporary store, warehouse, lodging, or other purpose at a construction site. In this case, the corner columns 10 include main columns 11 and sub-columns 12, increasing the strength of the corners and providing stable support despite the simple structure. Furthermore, the inner corners are covered with inner corner covers 30, improving the appearance quality of the inner corners despite the simple structure. Furthermore, the inner surfaces of the columns 10 between the corners are covered with inner intermediate covers 31, improving the appearance quality in combination with the inner corner covers 30 despite the simple structure. In particular, the inner intermediate covers 31 protrude inward by their thickness, but this is visually recognizable as if they were columns, further improving the appearance quality. Furthermore, since the outside of the corner support 10 is covered with the outer corner cover 32, the appearance quality of the outside of the corner support 10 can be improved with a simple structure.

[0037] In this simple house H, for example, when it is installed or when it is transported by truck and used at another location, it may be necessary to change the positions of the doors or windows. In this case, as shown in FIG. 7, the nuts 25 are loosened and removed from the bolts 23 of the necessary wall panels 20, in the reverse order of assembly. Then, a worker holds the wall panel 20 by hand and removes the bolts 23 of the support 10 from the bolt insertion holes 24 of the flanges 22 of the wall panel 20, and moves it to the desired position. Thereafter, as described above, the bolts 23 of the support 10 are inserted into the bolt insertion holes 24 of the flanges 22 of the wall panel 20, and the wall frame 21 is supported by being loosely inserted into the corresponding wall space E. Then, nuts 25 are screwed onto each bolt 23 and tightened, pressing the flanges 22 against the support 10. This fixes the wall panel 20 to the corresponding wall space E. In this case, the wall panel 20 can be replaced by simply removing and attaching the nuts 25 without removing the roof 4. In other words, unlike the conventional method, the roof 4 does not need to be lifted up by a crane or the like each time it is removed or attached, thereby improving the efficiency of the work of replacing the wall panel 20.

[0038] Furthermore, because the wall panel 20 is removed toward the outside, not the inside, and attached from the outside, it does not need to be lifted up as in the conventional method, making it easy to attach and detach, which also improves workability. Furthermore, because the wall panel 20 is fastened only with nuts 25, the structure is simplified and costs reduced. Furthermore, because the bolts 23 are installed only on the support columns 10, and the bolt insertion holes 24 are formed only in the portions of the flange 22 that abut against the support columns 10, the structure is simplified and fewer nuts 25 are required compared to a case in which bolts 23 are installed on all of the floor frame 1, roof frame 3, and adjacent pairs of support columns 10 that form the wall space E, and bolt insertion holes 24 corresponding to these bolts 23 are formed around the entire circumference of the flange 22 of the wall panel 20. This simplifies the replacement of the wall panel 20 and further improves the efficiency of the replacement work. In this case, the wall frame 21 is loosely inserted into the wall space E, and the flanges 22 abut against the floor frame 1, the roof frame 3 and a pair of adjacent columns 10, so that the support of the wall panel 20 is not impaired.

[0039] Furthermore, by providing a plurality of groups (two in the embodiment) of columns 10 each having the same spacing between adjacent pairs of columns 10, but with different spacing dimensions between the columns 10, i.e., by providing one group (a group of columns 10 Ga) and the other group (a group of columns 10 Gb), the number of patterns for rearranging the wall panels 20 increases, thereby improving versatility.

[0040] FIG. 8 shows a modified example of a support column 10 provided at a corner. At the corner of the floor frame 1 and the corner of the roof frame 3, the rods of the floor frame 1 and the roof frame 3 extend, bending at 90° around the main support column 11, and the sub-support column 12 is installed between the extending rods of both floor frames 1 and the roof frame 3. The presence of two sub-support columns 12 further increases the strength. The sub-support column 12 may be installed between the rods on either one or the other of the extending sides. That is, one or two may be used. Also, the sub-support column 12 need not be provided.

[0041] In the above embodiment, the number of columns 10 and the number of wall panels 20 are not limited to those described above and may be changed as appropriate. The configuration of the wall panels 20 is also not limited to those described above and may be changed as appropriate. Wall space E may be provided with irreplaceable wall panels, or there may be wall spaces without wall panels, and these changes may be made as appropriate. Those skilled in the art will easily make many modifications to these exemplary embodiments without substantially departing from the novel teachings and advantages of the present invention, and these many modifications are within the scope of the present invention.
