For this reason, in the field construction after installing the first unit 11, the workability can be improved without the rope hooking portion 160 interfering. Moreover, since the rope hook part 160 does not get in the way, it is possible to increase the degree of freedom in designing the part other than the building unit 1 of the building.

  Similarly, the through-hole 111 provided in the lower plate 110 can be viewed through the open surface of the space 170. Therefore, the anchor bolt protruding from the foundation 3 inserted into the through hole 111 can be easily fastened using a nut or the like. That is, the column base metal fitting 100 according to the present embodiment has a structure that can be connected and fixed to the foundation 3 after being connected to the column 31 and the base 32. Specifically, even after being connected to the pillar 31 and the base 32, a structure (through hole 111) used for connection to the foundation 3 is provided so as to be exposed to the outside.

  The rope hook 160 protrudes from the upper plate 120 so that the tip is separated from the lower plate 110. Specifically, the rope hooking portion 160 is a columnar portion that protrudes from the lower surface of the upper plate 120 toward the lower plate 110 so that the lower end (that is, the tip) is separated from the lower plate 110. In the present embodiment, the shape of the rope hook 160 is a cylinder, but may be a prism.

  In the present embodiment, the rope hooking portion 160 has an enlarged diameter portion 161 provided at the tip. Although the enlarged diameter part 161 is disk shape, for example, it is not limited to this. The enlarged diameter portion 161 may have a rectangular plate shape, or only a part of the tip may protrude in a bowl shape. By providing the enlarged diameter portion 161 at the tip of the rope hook 160, the hooked rope can be made difficult to come off.

  In addition, although FIG. 8A and 8B demonstrated the column base metal fitting 100 provided with the three base connection parts 150, it is not restricted to this. For example, the column base metal fitting used for the corner portion of the first unit 11 may include only one or two base connection portions 150. That is, the number and arrangement of the base connection portions 150 included in the column base metal are determined according to the number and arrangement of the bases 32 to which the column base metal is connected.

  Similarly, in this Embodiment, the column base metal fitting 100 provided with the rope hook part 160 was connected to each of all the columns 31 with which the 1st unit 11 is provided, but it is not restricted to this. In other words, all the column base fittings included in the first unit 11 may not include the rope hanging portion 160, and at least one column base fitting may include the rope hanging portion 160.

[Second unit]
Then, the 2nd unit 12 which comprises the 2nd floor of the building unit 1 is demonstrated using FIG.1, FIG.2 and FIG.4.

  The second unit 12 is different from the first unit 11 in that the recess 2 is not provided, but the second unit 12 may also be provided with the recess 2. The first unit 11 may not be provided with the recess 2.

You may slide it.

[Suspension]
Here, the lifting tool 200 used for lifting the first unit 11 will be described with reference to FIGS. 11 and 12.

  FIG. 11 is a perspective view of a hanging tool 200 used for lifting the first unit 11 according to the present embodiment. FIG. 12 is a three-side view of the hanging bracket 210 used for lifting the first unit 11 according to the present embodiment. Specifically, FIG. 12A is a plan view (top view) of the hanging bracket 210, FIG. 12B is a front view, and FIG. 12C is a side view (right side view).

  As shown in FIG. 11, the hanger 200 includes a hanger 210 and a plurality of ropes 220 (only one is shown in the figure).

  The hanging metal fitting 210 is a metal rectangular frame. The hanging bracket 210 is made of, for example, iron or a metal alloy such as stainless steel or carbon steel. In the present embodiment, as shown in FIG. 12, the hanging metal fitting 210 includes a frame portion 211, a plurality of first rope hanging portions 212, and a plurality of second rope hanging portions 213.

  The frame portion 211 is a main body of the hanging bracket 210 and is formed in a substantially rectangular frame shape. Specifically, the frame portion 211 has an H-shaped reinforcing portion spanned inside a substantially rectangular frame. The frame portion 211 is formed by combining a plurality of H-shaped steels with fasteners such as bolts and nuts. The frame part 211 is substantially the same size as the first unit 11 in plan view.

  The plurality of first rope hook portions 212 are provided along the outer periphery of the frame portion 211. Each of the plurality of first rope hooks 212 is a plate provided with a notch-shaped recess 212a, and is fixed to the side surface of the frame 211 by welding or a fastener. The first rope hook portion 212 may also be provided in an H-shaped reinforcing portion that is spanned inside a substantially rectangular frame.

  The recess 212 a is provided at the upper end of the first rope hook 212. The rope 220 is hung on the recess 212a, so that the rope 220 can be prevented from dropping off.

  The plurality of second rope hook portions 213 are provided on the upper portion of the frame portion 211. The plurality of second rope hooks 213 are used to fix the hook of the crane and the hanging bracket 210 when the hanging bracket 210 is lifted by a crane or the like. Specifically, a rope connected to the hook of the crane is hung on the second rope hook 213.

  As shown in FIG. 11, the plurality of ropes 220 includes a first rope 221, a second rope 222, and a turnbuckle 223.

  The first rope 221 is a wire rope made of metal such as stainless steel. The first rope 221 is provided with rings 221a and 221b at both ends. The wheel 221a of the first rope 221 is hooked on the recess 212a of the first rope hook 212, and one end of the turnbuckle 223 is connected to the wheel 221b.

Specifically, the turnbuckle 223 adjusts the tension applied to the rope 220 by adjusting the entire length of the rope 220. Thereby, since the tension | tensile_strength concerning each of several rope 220 can be adjusted, the hanging bracket 210 and the 1st unit 11 can be lifted with sufficient balance.

  Each of the plurality of ropes 220 may be composed of only one rope. For example, a rope having a length corresponding to the height of the first unit 11 can be used.

[Unit placement]
Then, the process of lifting the 1st unit 11 using the hanging tool 200 mentioned above and mounting in the foundation 3 is demonstrated using FIG. 13A-FIG. 13D.

  FIG. 13A is a perspective view for explaining a state in which the rope 220 is hung on the hanging bracket 210 in the installation method of the building unit 1 according to the present embodiment. FIG. 13B is a side view for explaining a state where the rope 220 is hung on the rope hanging portion 160 of the column base metal 100 in the installation method of the building unit 1 according to the present embodiment. FIG. 13C is a perspective view for explaining a state in which first unit 11 is lifted in the installation method for building unit 1 according to the present embodiment. FIG. 13D is a perspective view for explaining how the first unit 11 is installed and fixed to the foundation 3 in the installation method of the building unit 1 according to the present embodiment.

  In the present embodiment, the first unit 11 is mounted on the foundation 3 by hanging the hanging tool 200 on the locking structure of the first unit 11 (specifically, the rope hanging portion 160 of the column base metal 100). Put.

  First, a hanging tool 200 is prepared at a construction site. Specifically, the rope 220 is hung on the first rope hook 212 of the hanging bracket 210. In the present embodiment, as shown in FIG. 13A, the ring 221a of the first rope 221 is hung on the recess 212a of the first rope hook 212.

  The number of ropes 220 to be hung on the hanging bracket 210 is not particularly limited, but the first unit 11 can be stably lifted by hanging at least four ropes 220. Moreover, you may assemble the hanging bracket 210 at a construction site as needed.

  Next, the hanging bracket 210 is disposed above the first unit 11. Specifically, the suspension fitting 210 is lifted by a crane and disposed above the first unit 11. In the present embodiment, the crane hook 300 and the second rope hook 213 of the hanging bracket 210 are connected by a rope. The crane lifts the hook 300 to the height of the first unit 11 and moves it horizontally, so that the hanging bracket 210 is disposed above the first unit 11.

  Next, the rope 220 is hung on the rope hook 160 of the first unit 11. Specifically, as shown in FIG. 13B, the ring 222 a of the second rope 222 is hung on the rope hook 160. Thereafter, by operating the turnbuckle 223, the length of the rope 220 is adjusted, and the tension applied to the rope 220 is adjusted.

  In the present embodiment, since the plurality of ropes 220 are used for supporting (lifting) the unit 10 having a large weight, sufficient strength is required. For this purpose, a metal wire rope is used for the first rope 221 and the second rope 222. Metal wire ropes are difficult to deform with force, and are difficult to tie or untie when hanging the rope.

  Here, in the column base 100, the rope hooking portion 160 and the lower plate 110 are separated from each other, so that the ring 222a of the second rope 222 can be hung as it is. That is, instead of tying or unfastening the rope 220, it is only necessary to hook the ring 222a provided at the end in advance through the rope hook 160. Thereby, the 1st unit 11 can be appropriately lifted.

  After adjusting the lengths of all the ropes 220, the crane raises the hook 300, whereby the hanging bracket 210 is lifted as shown in FIG. 13C, and the first unit 11 is also lifted in conjunction with the hanging bracket 210. .

  At this time, the fixture 230 may be provided on the column 31 of the first unit 11. That is, in the present embodiment, the hanging bracket 210 may be lifted after the upper portion of the column 31 and the hanging bracket 210 are fixed.

  The fixing tool 230 is a square member connected to the side surface of the column 31. As shown in FIG. 13C, the fixture 230 is provided so as to protrude upward from the upper end of the column 31. Specifically, the fixture 230 protrudes with a length equal to or longer than the distance between the hanging bracket 210 and the column 31 in a state where the hanging bracket 210 and the first unit 11 are connected by the rope 220.

  In the present embodiment, the planar view shape of the hanging bracket 210 is substantially the same as the planar view shape of the first unit 11. For this reason, the fixture 230 abuts on the hanging bracket 210. For example, by attaching a plurality of fixtures to the pillars 31 on different side surfaces of the first unit 11, the movement of the hanging bracket 210 in the horizontal direction can be restricted.

  Next, as shown in FIG. 13D, the first unit 11 is placed on the foundation 3 by horizontally moving and lowering the first unit 11. At this time, the anchor bolt 4 protruding upward from the foundation 3 is inserted into the through hole 111 of the column base metal 100.

  After placing the first unit 11, the rope 220 is removed. Specifically, the rope 220 can be easily detached from the rope hook 160 by loosening the turnbuckle 223 and increasing the length of the rope 220. At this time, since the rope 220 can be removed between the first floor and the second floor, it is not necessary to perform work at a high place.

  Next, the column base metal 100 is connected and fixed to the foundation 3 with a fastener. Specifically, the column base metal 100 is fixed to the foundation 3 by fastening the anchor bolt 4 and the nut with the lower plate 110 of the column base metal 100 interposed therebetween.

  As described above, the first unit 11 can be placed on the foundation 3 and fixed.

  After placing the first unit 11 on the foundation 3, the beams are connected to the upper portions of the plurality of columns 31. In the present embodiment, the horizontal member 42 of the second unit 12 is connected as an upper beam of the first unit 11. That is, the second unit 12 is placed on the first unit 11 by performing the same operation as that shown in FIGS. 13B to 13D on the second unit 12.

Therefore, when the face material 33 is not provided, the first unit 11 is deformed or Easy to break. Specifically, when the first unit 11 is lifted, the load of the watering equipment is applied to the base 32 and the like, and the plurality of pillars 31 may be inclined. In other words, the first unit 11 may be deformed so that the upper portions of the plurality of pillars 31 approach each other or away from each other.

  On the other hand, in this Embodiment, since the face material 33 is spanned on the upper part of the some pillar 31 except a construction site, the face material 33 can ensure the distance of the upper part of the some pillar 31. FIG. Since it can do, approach and separation can be controlled. Therefore, the first unit 11 can be prevented from being deformed or damaged when the first unit 11 is lifted.

  Thus, the strength of the first unit 11 can be sufficiently ensured by providing the face material 33 without providing a beam or the like. Therefore, since the deformation | transformation or damage of the 1st unit 11 can be suppressed, the height of a ceiling can be ensured high.

(Other)
As mentioned above, although the column base metal fittings, building unit, and the installation method concerning the present invention were explained based on the above-mentioned embodiment and its modification, the present invention is not limited to the above-mentioned embodiment.

  For example, in the above embodiment, the example in which the building unit 1 includes the two units 10 has been described. However, the building unit 1 may include only one unit or three or more units 10.

  Further, for example, in the above-described embodiment, the example in which the two units 10 respectively configure the first floor and the second floor of the building is shown, but the present invention is not limited thereto. Each unit 10 may constitute an upper floor of three or more floors, or may constitute an underground floor such as the first basement floor.

  Further, for example, in the above-described embodiment, the rope hooking portion 160 protrudes from the upper plate 120, but is not limited thereto. The rope hook 160 may protrude from the lower plate 110 or the vertical plate 130. For example, the rope hook 160 may protrude from the upper surface of the lower plate 110 in a bowl shape (for example, an inverted J shape). Alternatively, the rope hook 160 may protrude from the inner side surface of the vertical plate 130 in a hook shape (for example, an L shape) whose tip is directed downward. In either case, the rope 220 can be locked by keeping the tip of the rope hooking portion 160 away from the lower plate 110.

  Further, for example, the rope hooking portion 160 is provided between the lower plate 110 and the upper plate 120, but is not limited thereto. The rope hook 160 may be provided to protrude outward from the space 170 surrounded by the lower plate 110, the upper plate 120, and the three vertical plates 130.

  In addition, for example, the rope hanging portion 160 may not include the enlarged diameter portion 161. For example, the rope hooking portion 160 may have a conical or pyramidal shape that becomes narrower at the tip.

  Further, for example, in the above-described embodiment, the example in which the column base metal fitting 100 includes the three vertical plates 130 as the support portion is shown, but the present invention is not limited thereto. The vertical plate 130 may be one or two, or four or more. Alternatively, the support portion may be a prism having a recess. A rope hook 160 may be provided in the recess.

  Further, for example, in the above-described embodiment, the example in which the first unit 11 includes the same number of column bases 100 as the plurality of columns 31 is shown, but the present invention is not limited thereto. The number of column bases 100 may be less than the number of columns 31, and some of the columns 31 may be directly fixed to the base 32.

  For example, in the above-described embodiment, the example in which the unit 10 is suspended using the rope 220 has been described. However, the case of the second unit 12 that does not include the column base 100 is not limited thereto. That is, the locking structure provided in the lower part of the unit 10 is not limited to a structure in which the rope 220 can be locked. For example, the locking structure may be a through hole, and the hanging tool may be a metal bar (for example, an iron bar) provided with a bolt at the tip and a nut. In this case, the metal rod is fixed to the lower portion of the unit 10 by inserting the metal rod into a through hole provided in the lower portion of the unit 10 and fastening with a nut. Thereafter, the unit 10 can be suspended by lifting the metal rod.

  Further, for example, in the above-described embodiment, an example in which one or more units 10 are formed by a wooden shaft assembly method is shown, but the present invention is not limited thereto. For example, a wooden frame wall construction method such as a 2 × 4 construction method or another construction method such as a steel frame construction may be used. Therefore, for example, the pillars 31 and 41 are not limited to wood but may be steel frames. Further, the columns 31 and 41 may be part of the frame.

  In addition, the embodiment can be realized by arbitrarily combining the components and functions in each embodiment without departing from the scope of the present invention, or a form obtained by subjecting each embodiment to various modifications conceived by those skilled in the art. Forms are also included in the present invention.
