Description

[Technical Field]

[0001] The present invention relates to modular houses, that is, box-shaped buildings that are pre-assembled in a factory, and particularly to wooden buildings (where the structural elements such as pillars and beams are constructed from wood). [Background technology]

[0002] Modular houses can minimize the amount of work required on-site and provide living space in a short amount of time, so they are attracting attention not only for use as homes or offices, but also as a means of quickly securing living space for evacuees in the event of a natural disaster.In particular, in recent years, not only the construction work such as assembly, but also the interior finishing work such as wallpaper and furniture is often done in advance in factories, making it possible to secure living space even more quickly.

[0003] However, if a modular house with completed interior finishing cannot be kept level during crane work (lifting, suspending, and horizontal movement) when installing it on site or lifting it onto a truck bed, the entire modular house may twist, causing problems with the interior, such as cracks and wrinkles in the wallpaper.

[0004] Therefore, a known structure is one in which a hoisting fixture is attached to the modular house itself to easily keep it level during crane work. For example, the modular house in Patent Document 1 below has a structure in which a hoisting fixture is attached to the upper part of the roof surface. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-100333 Summary of the Invention [Problem to be solved by the invention]

[0006] The modular house in Patent Document 1 has the advantage that the hanging hardware attached to the roof allows for easy crane work while maintaining horizontality. However, when attaching the hanging hardware, it is necessary to create through holes in the roof material, and these through holes may become a cause of leaks. [Means for solving the problem]

[0007] The present invention has been developed to effectively solve the problems associated with the conventional modular houses described above.

[0008] In essence, the modular house of the present invention is a wooden modular house with an overall rectangular parallelepiped shape, in which a pair of opposing ceiling beams are assembled in a square shape, with anchors made of rods protruding outward, and a hanging hardware that projects outward from the exterior wall is attached via the anchors, with an engaging part at the free end of the hanging hardware that engages with the lifting tool of a crane. This allows the hanging hardware to be attached without drilling holes in the roof material.

[0009] Preferably, the hanging hardware comprises a fixed wall portion fixed along the outer wall by the anchor, a hanging wall portion extending outward from the upper end of the fixed wall portion, and a pair of side wall portions connecting the left and right ends of the hanging wall portion and the fixed wall portion, and by providing the engagement portion at the free end of the hanging wall portion, the fixed wall portion can be firmly fixed along the outer wall and the hanging wall portion can be firmly supported by the fixed wall portion and the side wall portions.

[0010] More preferably, the hanging fitting has a first reinforcing wall portion between the pair of side wall portions that connects the hanging wall portion and the fixed wall portion, and is parallel to each of the side wall portions, and a second reinforcing wall portion that connects the hanging wall portion and the pair of side wall portions is provided along a direction perpendicular to the first reinforcing wall portion, thereby enabling the hanging wall portion to be supported even more firmly.

[0011] Furthermore, since the first reinforcing wall portion and the second reinforcing wall portion of the hanging fitting intersect, the support structure of the hanging wall portion can be made even stronger.

[0012] Furthermore, since the engaging portion is a through hole drilled in the free end of the hanging wall portion or a metal fitting with a ring erected on the free end of the hanging wall portion, it can have a simple structure and can engage with the crane's lifting equipment appropriately even if there is a protrusion such as an eaves.

[0013] Preferably, the fixed wall portion of the hanging hardware is fixed at a distance from the outer wall via a spacer, thereby preventing the outer wall from being accidentally damaged.

[0014] In addition, the anchor can be integrated with the ceiling beam by embedding the part other than the protruding part in the ceiling beam, or by inserting the part other than the protruding part into the ceiling beam and screwing a nut onto the inserted end, thereby firmly fixing the hanging hardware. [Effects of the Invention]

[0015] According to the modular house of the present invention, lifting, suspending, horizontal movement, etc. can be easily performed using a crane, and since there is no need to drill holes in the roof, there is no need to worry about rain leaks.

[0016] In addition, since the hanging hardware protrudes from the exterior wall, even if there is a protrusion such as an eaves, the crane can be used to avoid the protrusion and perform crane work, and the hanging hardware can also be used to secure the load when it is loaded onto the truck bed.

[0017] After installation, the hanging hardware can be removed to expose the anchor, which can then be used to join the modular houses together. [Brief explanation of the drawings]

[0019] BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will now be described with reference to FIGS.

[0020] <Basic structure of a modular house> As shown in Figs. 1 and 2, a modular house 1 according to the present invention is a wooden modular house having an overall rectangular parallelepiped shape, and structural members such as pillars and beams are constructed of wood.

[0021] The modular house 1 according to the present invention is characterized by the provision of hanging hardware 3 that protrudes outward from the exterior wall 1c. As shown in Figure 1, the hanging hardware 3 is provided by attaching anchors 2 made of rod material to a pair of opposing ceiling beams 1a that are assembled in a square shape, protruding outward, and as shown in Figure 2, the hanging hardware 3 is provided by attaching anchors 2 to the exterior wall 1c.

[0022] <About Anchor 2> There are no particular limitations on the anchor 2 as long as it is a rod material with high shear strength, but a round rod material made of metal or synthetic resin is preferred, and more preferably, a rod material with a thread groove on the outer surface, such as a cut bolt, as shown in Figure 3. This is because, as will be described later, it allows for easy and appropriate embedding and bolt tightening.

[0023] A known spacer nut or a plurality of nuts 5 as shown in FIG. 3 is screwed onto the anchor 2, and used as a spacer between the fixed wall portion 3A of the hanging hardware 3 (described later) and the outer wall 1c.

[0024] 3(A), it is desirable to embed the portion (non-protruding portion) 2b of the anchor 2 other than the protruding portion 2a in the ceiling beam 1a. This is to integrate the anchor with the ceiling beam 1a and firmly secure and support the hanging hardware 3. To explain in detail how to embed the anchor 2, a bottomed hole 1b is drilled in the ceiling beam 1a, the non-protruding portion 2b of the anchor 2 is inserted into the hole 1b, and a known adhesive G such as an epoxy adhesive is injected between the outer surface of the non-protruding portion 2b and the inner surface of the hole 1b and allowed to harden.

[0025] Alternatively, as shown in Figure 3(B), the anchor 2 can be protruded by inserting the non-protruding portion 2b into the ceiling beam 1a and screwing a nut 9 onto the inserted end, thereby integrating it with the ceiling beam 1a and firmly fixing and supporting the hanging hardware 3. In more detail, by drilling a through-hole 1b in the ceiling beam 1a, inserting the non-protruding portion 2b into said hole 1b, and screwing a nut 9 onto the tip of the inserted non-protruding portion 2b, said nut 9 can work together with the previously mentioned spacer nut or double nut 5 which serves as a spacer to firmly fix and support the anchor 2.

[0026] As shown in Figure 1, it is desirable to install at least two anchors 2 protruding from each of the opposing ceiling beams 1a in order to provide at least four hanging fittings 3. It is also desirable to install at least four anchors 2 protruding from each location in order to firmly secure and support the fixed wall portion 3A of the hanging fitting 3, which will be described later.

[0027] Furthermore, it is desirable to protrude the anchors 2 from the ceiling beams 1a that make up the non-joint surface 1A where entrances and exits are located, rather than from the joint surface 1B of the modular house 1 (the surface that butts up against another modular house 1). As will be described later, this is because they are used to join modular houses 1 together. In other words, it is desirable to protrude the anchors 2 from the ceiling beams 1a that make up the non-joint surface 1A on the gable side of the modular house 1, rather than from the joint surface 1B on the flat side.

[0028] <About Hanging Bracket 3> The sling 3 can be fixed with the anchors 2 described above, and it is sufficient that it has an engaging portion at its free end that can engage with a sling device such as a crane hook. Although not specifically shown, it may be, for example, a columnar body that is fixed and supported by four anchors 2, and has holes or rings at its free end for hooking onto.

[0029] In the present invention, as shown in Figs. 4 to 6, it is preferable to use a sling 3 that has a simple structure made of a panel-like member, yet can be firmly fixed and contribute to stable crane operation.

[0030] In more detail, the hanging hardware 3 of the present invention comprises a fixed wall portion 3A in the form of a rectangular panel that is fixed by an anchor 2, a hanging wall portion 3B in the form of a rectangular panel that extends outward from the upper end of the fixed wall portion 3A, and a pair of panel-shaped side wall portions 3C that connect the left and right ends of the hanging wall portion 3B to the left and right ends of the fixed wall portion 3A, respectively, and is configured to have an engagement portion 4 at the free end of the hanging wall portion 3B.

[0031] An anchor insertion hole 3a is drilled in the fixed wall portion 3A, and by inserting the protruding portion 2a of the anchor 2 into the anchor insertion hole 3a and screwing a nut 6 onto the protruding portion 2a, the fixed wall portion 3A can be easily and firmly fixed and supported along the outer wall 1c, thereby firmly fixing and supporting the hanging hardware 3.

[0032] In the present invention, the hanging hardware 3 further includes a first reinforcing wall 3D between the pair of side walls 3C that connects the hanging wall 3B and the fixed wall 3A, and is provided parallel to each side wall 3C, and a second reinforcing wall 3E that connects the hanging wall 3B and the pair of side walls 3C is provided along a direction perpendicular to the first reinforcing wall 3D, thereby providing further reinforcement and firmly supporting the hanging wall 3B.

[0033] As described above, the fixed wall portion 3A is fixed with the spacer spaced apart from the outer wall 1c, so there is no risk of accidentally damaging the outer wall 1c during crane operation.

[0034] As shown in Figures 5 and 6, the engagement portion 4 provided at the free end of the hanging wall portion 3B is preferably used by fastening a metal fitting with a ring 4a, such as an eye nut, with a bolt 7 via a through hole 3b drilled in the free end. Of course, an eye bolt can also be used. Using a metal fitting with a ring in this way makes it easier to engage with the lifting gear of a crane. However, in the present invention, it is also possible to use the through hole 3b itself as the engagement portion, depending on the implementation.

[0035] As explained above, with the modular house 1 according to the present invention, as shown in FIG. 2, lifting, suspending, horizontal movement, etc. can be easily performed using the lifting device 8 consisting of the crane's balance 8a, chain 8b, and hook 8c, and there is no need to drill holes in the roof, so there is no need to worry about leaks.

[0036] Furthermore, the hanging hardware 3 of the present invention can be easily constructed by combining panel-like members, while also being able to firmly fix and support the hanging wall portion 3B equipped with the engagement portion 4, thereby enabling proper crane operation and preventing problems from occurring in the interior.

[0037] Furthermore, the hanging fitting 3 protrudes from the exterior wall 1c, and by providing an engagement portion 4 at the free end of the hanging wall portion 3B of the hanging fitting 3, the crane's hanging tool 8 can be engaged at a distance from the exterior wall 1c, so that even if there is a protrusion such as an eaves, crane work can be performed while avoiding the protrusion.

[0038] As shown in FIG. 7, when the modular house 1 is loaded on the bed of a truck T, a securing belt B can be hung over the sling 3 to secure the modular house 1 in place.

[0039] After installation, as shown in Figure 8, the hanging hardware 3 can be removed to expose the anchors 2, and the joint panel P can be fixed via the exposed anchors 2, contributing to the joints between modular houses. For example, the joint panel P can be a panel made of a material that combines design and durability, such as known laminated lumber. [Explanation of symbols]
