Description

[Technical field]

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

[0002] Modular houses can minimize the amount of work required at the installation site and provide living space in a short time, so they are attracting attention not only for use as residences or offices, but also as a means of quickly providing living space for evacuees in the event of a natural disaster. In recent years, modular houses have been built with not only the construction work of assembly, but also the interior finishing work of wallpapering and furniture often carried out in advance at factories, making it possible to provide living space in an even shorter time.

[0003] However, if a modular house whose interior has already been finished cannot be kept level reliably during crane work (lifting, suspending and horizontal movement) when setting up on site or lifting and lowering it onto the truck bed, the entire modular house may twist, causing the wallpaper to crack or wrinkle, and other problems with the interior.

[0004] Therefore, in order to easily keep the prefabricated house horizontal during crane work, a structure is known in which a hanging bracket is provided on the prefabricated house itself. For example, the prefabricated house in the following Patent Document 1 has a structure in which a hanging bracket is provided that protrudes upward from the upper part of the roof surface.

[0005] [Patent Document 1] JP 2004-100333 A Summary of the Invention [Problem to be solved by the invention]

[0006] The modular house in Patent Document 1 above has the advantage that the hanging fittings attached to the roof make it easy to perform crane work while keeping the roof level. However, when attaching the hanging fittings, it is necessary to make through holes in the roof material, and these through holes may cause leaks. [Means for solving the problem]

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

[0008] In essence, the modular house of the present invention is a wooden modular house with an overall rectangular parallelepiped shape, in which anchors made of rod material are attached to a pair of opposing ceiling beams that are assembled in a square shape, hanging hardware is attached to the outside of the exterior wall via the anchors, and an engagement part is provided at the free end of the hanging hardware to engage with the lifting tool of a crane. This means that the hanging hardware can 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 can further firmly support the hanging wall portion by providing a first reinforcing wall portion between the pair of side wall portions, connecting the hanging wall portion and the fixed wall portion parallel to each of the side wall portions, and by providing a second reinforcing wall portion connecting the hanging wall portion and the pair of side wall portions along a direction perpendicular to the first reinforcing wall portion.

[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 engagement portion is a through hole drilled into 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, the structure can be simplified and the engagement portion can appropriately engage with the lifting gear of the crane even if there is a protrusion such as an eaves.

[0013] Preferably, the fixed wall portion of the hanging metal fitting 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. Effect of the Invention

[0015] The modular house of the present invention can easily be hoisted, suspended, and moved horizontally using a crane, and there is no need to drill holes in the roof, so there is no need to worry about rain leaks.

[0016] In addition, because the hanging fittings protrude from the exterior wall, even if there is a protrusion such as a eaves, the crane can perform work by avoiding the protrusion, and the hanging fittings can also be used to secure the load when it is loaded onto the bed of a truck.

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

[0019] BEST MODE FOR CARRYING OUT THE DISCLOSURE Hereinafter, the best mode for carrying out the present invention will be described with reference to Figs.

[0020] <Basic structure of 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 its structural members such as pillars and beams are constructed of wood.

[0021] The modular house 1 according to the present invention is characterized in that it is provided with hanging fittings 3 that protrude outward from the exterior wall 1c. As shown in Fig. 1, the hanging fittings 3 are 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 protruding outward from the exterior wall 1c via the anchors 2, as shown in Fig. 2.

[0022] <About Anchor 2> There are no particular limitations on the anchor 2 so long as it is a rod material with high shear strength, but it is preferable to use a round rod material made of metal or synthetic resin, and more preferably, a rod material with a thread groove engraved on its outer periphery, such as a cut bolt, as shown in Fig. 3. This is because, as will be described later, embedding and bolting can be performed easily and appropriately.

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

[0024] 3(A), it is preferable to embed the portion (non-protruding portion) 2b other than the protruding portion 2a of the anchor 2 in the ceiling beam 1a. This is to integrate the anchor with the ceiling beam 1a and firmly fix and support the hanging hardware 3. To explain embedding the anchor 2 in detail, 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 peripheral surface of the non-protruding portion 2b and the inner peripheral surface of the hole 1b and allowed to harden.

[0025] 3(B), the anchor 2 can also 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 the hole 1b, and screwing a nut 9 onto the end of the inserted non-protruding portion 2b, the nut 9 can work together with the previously mentioned spacer nut or double nut 5 instead of a spacer to firmly fix and support the anchor 2.

[0026] As shown in Fig. 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 of the opposing ceiling beams 1a in order to firmly fix and support the fixed wall portion 3A of the hanging fittings 3, which will be described later.

[0027] Also, it is preferable that the anchor 2 protrudes from the ceiling beam 1a constituting the non-joint surface 1A where an entrance and the like is located, rather than the joint surface 1B (the surface that butts against another unitary house 1) of the unitary house 1. As will be described later, this is because it is used to join unitary houses 1 together. In other words, it is preferable that the anchor 2 protrudes from the ceiling beam 1a constituting the non-joint surface 1A, which is the gable side, rather than the joint surface 1B, which is the flat side, of the side surfaces of the unitary house 1.

[0028] <About hanging bracket 3> The hoisting hardware 3 may be fixed by the above-mentioned anchors 2, and may have an engagement portion at its free end for engaging with a hoisting device such as a crane hook. Although not specifically shown, it may be, for example, a hoisting hardware that is a columnar body fixed and supported by four anchors 2, and has a hole or ring at its free end for hanging a hook.

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

[0030] In detail, the hanging hardware 3 of the present invention comprises a fixed wall portion 3A in the form of a rectangular panel fixed by an anchor 2, a hanging wall portion 3B in the form of a rectangular panel extending outward from the upper end of the fixed wall portion 3A, and a pair of panel-shaped side wall portions 3C connecting 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 provided 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 enabling the hanging hardware 3 to be firmly fixed and supported.

[0032] In the present invention, the hanging fitting 3 further includes a first reinforcing wall 3D between the pair of side walls 3C, which 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 connecting the hanging wall 3B and the pair of side walls 3C is provided along a direction perpendicular to the first reinforcing wall 3D. This provides further reinforcement and allows the hanging wall 3B to be firmly supported.

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

[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 fixing 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. By using a metal fitting with a ring in this way, it is possible to easily engage with the lifting tool of a crane. However, in the present invention, it is optional to use the through hole 3b itself as the engagement portion depending on the implementation.

[0035] As described above, with the modular house 1 of the present invention, as shown in FIG. 2, operations such as lifting, suspending, and horizontal movement can be easily performed using the hoisting device 8 consisting of a crane balance 8a, chain 8b, and hook 8c, and since there is no need to drill holes in the roof, 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 firmly fixing and supporting 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, by providing an engagement portion 4 at the free end of the hanging wall portion 3B of the hanging bracket 3, the crane's lifting device 8 can be engaged at a distance from the exterior wall 1c, so that even if there is a protrusion such as a eaves, crane operation can be performed while avoiding the protrusion.

[0038] Also, as shown in FIG. 7, when the modular house 1 is loaded on the bed of a truck T, a fastening belt B can be hung around the hoisting fitting 3 to secure the modular house 1 in place.

[0039] After installation, as shown in Fig. 8, the hanging fittings 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. As the joint panel P, for example, a panel made of a material that combines design and durability, such as known laminated lumber, can be used. [Explanation of symbols]
