Further, FIG. 3 is a plan view for explaining a state in which the fixing jigs 3A to 3D (3) are attached at positions where the four corners of the building unit 2 of the truck bed 1 are placed.

  First, the configuration of the building unit 2 will be described with reference to FIG. In addition, the structure of the building unit 2 demonstrated below is an example, and is not limited to this.

  The main structure of the building unit 2 is composed of four pillars 21 arranged at the corners, ceiling beams 27 spanned between the upper ends of the pillars 21, and so on. Are formed as a box-shaped frame structure (framework structure) by the short-side beams 22 and 22 and the long-side beams 23 and 23 passed as floor beams between the lower ends of 21 and so on.

  As shown in FIGS. 1 and 2, a joint frame member 24 </ b> A (24 </ b> B) having a substantially U-shaped cross-sectional view is disposed at the joint between the column 21 and the short side beam 22 (or the long side beam 23). That is, the end face of the joining frame member 24A (24B) is brought into contact with the side surface of the column 21, and joining is performed by welding, and the short side beam 22 (long side beam 23) is welded to the joining frame member 24A (24B). Joined by.

  Moreover, the lower surface of the column 21 formed of a square tubular steel pipe is covered with a lid 211 made of a steel plate, and a lower surface hole 21 a is provided in the approximate center of the lid 211.

  This building unit 2 is manufactured in a factory and transported to a construction site by a truck. At the construction site, a unit building (not shown) is constructed by connecting a plurality of building units 2.

  And the fixing jig 3 (3A-3D) is used in order to safely transport this building unit 2 to the construction site without damaging it. In addition, since the structure of the fixing jig 3A-3D is substantially the same, below, a structure is demonstrated using the code | symbol of the fixing jig 3. FIG.

  As shown in FIGS. 1 and 3, the fixing jig 3 fixes a plate-like plate portion 31 formed of a steel plate or the like, a column projection 4 provided on the plate portion 31, and the plate portion 31 to the loading platform 1. It mainly includes a fastening member 33 as a fastening means for doing this.

  In the plate portion 31, an underlay area 31 a disposed on the lower surface of the building unit 2 and an overhang area 31 b protruding from the side of the building unit 2 are formed.

  As shown in FIG. 1, the underlay region 31 a is a region disposed below the pillar 21 and the joining frame member 24 </ b> A. On the other hand, the overhang area 31 b is an area that protrudes to the outside of the building unit 2.

  The underlay region 31 a and the overhang region 31 b are formed of a substantially U-shaped cover portion 311 provided with the column protrusions 4, a rectangular plate-like long plate portion 312, and a horizontal mount installed on the long plate portion 312. And the material 32.

  Here, a part of the cover portion 311 and the long plate portion 312 becomes an underlay region 31a. Further, the remainder of the long plate portion 312 becomes a plate portion of the overhang region 31b that is continuous with the underlay region 31a, and the horizontal member 32 becomes a holding portion that is installed on the plate portion of the overhang region 31b.

  As shown in FIG. 3, the horizontal member 32 is bridged in the width direction of the loading platform 1 and serves as a holding portion for the left and right long plate portions 312 and 312. Such a horizontal member 32 is formed of a square steel pipe having a length substantially the same as the lateral width of the loading platform 1.

  Further, by welding the long plate portions 312 and 312 to the horizontal member 32, the distance between the long plate portions 312 and 312 can be accurately adjusted to the determined interval.

  And the side edge part 32a as shown in FIG. 1 is provided in the edge part of the both sides of the longitudinal direction of the horizontal member 32, respectively. The side end portion 32 a is mainly formed by a pair of opposing side plates 321, 321, a material portion 322 such as a bolt that spans between the side plates 321, 321, and a bottom plate 323 that closes between the lower ends of the side plates 321, 321. Composed.

  On the other hand, as shown in FIGS. 1, 4, and 5, the column protrusion 4 protruding upward from the cover portion 311 of the underlay area 31 a includes a conical pin portion 41 and a rotation shaft provided below the pin portion 41. A portion 42, a sheath tube portion 43 that rotatably accommodates the rotation shaft portion 42, and a lever portion 44 that extends laterally from the lower end of the rotation shaft portion 42 are provided.

  The pin portion 41 of the pillar protrusion 4 is provided at the position of the underlay region 31 a that faces the lower surface hole 21 a of the pillar 21. The bottom surface of the pin portion 41 is formed smaller than the diameter of the lower surface hole 21a. When the pin portion 41 is inserted into the lower surface hole 21a and then slid by operating the lever portion 44, the lid 211 around the lower surface hole 21a. A part of the pin portion 41 is placed on and fixed.

  The details of the column protrusion 4 will be further described with reference to FIGS. In FIG. 4A, the lever portion 44 on the left side (solid line) indicates the released state, and the lever portion 44 on the right side (two-dot chain line) indicates the fixed state.

  The center C1 of the pin portion 41 in the released state coincides with the center of the lower surface hole 21a, and the vertical movement of the lid 211 is not restricted by the pin portion 41. On the other hand, the axial center C2 of the cylindrical rotary shaft portion 42 having a smaller diameter than the bottom surface of the pin portion 41 is at a position eccentric from the center C1.

  When the lever portion 44 is turned in the direction of the arrow in FIG. 4A, the pin portion 41 is displaced from the lower surface hole 21a to the left as shown in FIG. 4B, and the side portion of the pin portion 41 is the lid 211. Will be on top. As a result, the lid 211 is in a fixed state in which the vertical movement of the lid 211 is limited by the pin portion 41.

  Further, stopper portions 46 and 46 for restricting the lever portion 44 so as not to go beyond the released state or the fixed state described above are provided on the side edges of the cover portion 311 that accommodates the rotating shaft portion 42 and the sheath tube portion 43. Each is provided.

  Further, the cover portion 311 is provided with lock portions 45, 45 as lock mechanisms on both sides of the rotating shaft portion 42. The lock portions 45, 45 are provided to maintain a released state or a fixed state.

  As shown in FIG. 5B, the lock portion 45 is provided by fixing a thin plate member formed in a step shape to the cover portion 311 with a bolt 45a. When the lever portion 44 is turned and applied to the lock portion 45, the lock portion 45 is lifted by elastic deformation and returns to the original position after passing the lever portion 44.

  As a result, the movement in the direction in which the lever portion 44 returns is restricted and locked. In short, the lever portion 44 stays between the lock portion 45 and the stopper portion 46 as shown in FIG.

  Further, by connecting a wire to the tip of the lever portion 44 and locking the other end of the wire, for example, by hooking it to a patch lock (catch clip) attached to the outer surface of the horizontal member 32, It becomes possible to visually confirm that it is locked.

  In addition, although the lock part 45 was illustrated in figure at step shape, it is not limited to this. For example, a strip-shaped protrusion may be attached to the front end side of the lower surface of the rectangular steel plate, and the steel plate may be elastically deformed by applying the lever portion 44 to the protrusion. A thick steel plate can be used as a leaf spring as compared with the case where the thin plate member is formed stepwise, and durability can be improved.

  The plate portion 31 configured as described above is fixed to the loading platform 1 by a fastening member 33 via a horizontal member 32. As shown in FIGS. 1 and 6, the fastening bracket 33 includes a main body portion 331 having an upper side 331 b and a lower side 331 a that are substantially U-shaped in side view, a fastening bolt 332 that is screwed into the upper side 331 b of the main body portion 331, and a lower side And a restricting portion 33a attached to 331a.

  An upper nut 332a is attached to the fastening bolt 332 above the upper side 331b of the main body 331, and is screwed into the lower nut 332b fixed to the lower surface of the upper side 331b.

  In order to fix the side end portion 32a of the horizontal member 32 to the loading platform 1, as shown in FIG. 1, the lower side 331a of the main body portion 331 of the fastening bracket 33 is applied to the lower surface of the loading platform 1, and the material of the side end portion 32a is fixed. The fastening bolt 332 is screwed into the material portion 322 from the upper side 331b covering the upper portion of the portion 322. Then, the horizontal member 32 is fastened to the loading platform 1 by the force pressing the material portion 322 with the tip of the fastening bolt 332.

  If the fastening member 33 is not attached to the horizontal member 32 in the correct orientation, the desired fastening force cannot be exhibited. Therefore, a restriction portion 33a for attaching the main body portion 331 of the fastening bracket 33 to the horizontal member 32 in the correct direction will be described with reference to FIG.

  In FIG. 6, the vertical direction of the main body 331 is opposite to the correct direction. Here, on the inner surface (the lower surface in FIG. 6) of the lower side 331 a of the main body 331, a long restricting portion 33 a wider than the distance between the pair of side plates 321 and 321 of the horizontal member 32 is fixed.

  For this reason, if an attempt is made to insert the lower side 331a of the main body 331 between the side plates 321 and 321 in the wrong direction (upside down direction), the restriction portion 33a cannot be inserted in contact with the side plate 321. The person can notice that the wearing direction is wrong.

  Next, the transportation method of the building unit 2 using the fixing jig 3 (3A-3D) of the present embodiment will be described, and the fixing jig 3 of the present embodiment and the transportation of the building unit 2 using the same will be described. The operation of the method will be described.

  As shown in FIG. 3, the truck bed 1 on which the building unit 2 is loaded has a rectangular planar shape that is substantially the same as or larger than the planar shape of the building unit 2. Here, the front edge of the loading platform 1 is the front edge 11, the right edge is the right edge 12, the rear edge is the rear edge 13, and the left edge is the left edge 14.

  First, the fixing jigs 3A to 3D are attached to positions where the four corners of the building unit 2 are to be placed on the truck bed 1. The fixing jigs 3 </ b> A and 3 </ b> B attached to the rear side of the loading platform 1 have the rear ends of the long plate portions 312 and 312 pressed by the horizontal member 32 that extends in parallel to the rear edge 13, The side end portions 32 a and 32 a are fastened to the loading platform 1.

  If fastening is performed by clamping the fastening bracket 33 in this manner, the fixing jigs 3A and 3B can be fixed on the loading platform 1 without performing special processing on the loading platform 1 of the truck.

  Furthermore, if it is the fastening metal fitting 33 of the structure clamp | tightened with the fastening bolt 332, it can confirm easily that predetermined | prescribed cargo fastening strength is ensured by managing the torque or tension | tensile_strength of the fastening bolt 332. FIG. In the conventional method of fixing with the load-clamping rope, it is difficult to make the material-clamping strength constant due to the expansion and contraction of the material.

  On the other hand, the fixing jigs 3 </ b> C and 3 </ b> D attached to the front of the loading platform 1 have the front ends of the long plate portions 312 and 312 held down by the horizontal member 32 that extends parallel to the front edge 11, Side end portions 32 a and 32 a are fastened to the loading platform 1.

  Here, by aligning the long plate portions 312 and 312 to the horizontal member 32 in advance by welding or the like in accordance with the interval between the columns 21 and 21 of the building unit 2, the positioning in the width direction of the loading platform 1 can be quickly performed. To be able to do that.

  Thus, the fixing jig 3A-3D fixed to the loading platform 1 is in a state where the lever portion 44 is directed to the release state side and the release is maintained by the lock portion 45.

  Then, a blade of a forklift (not shown) is inserted below the building unit 2 to be transported, and the building unit 2 is lifted horizontally. The building unit 2 may be lifted by a crane.

  Further, after the building unit 2 is carried to the vicinity of the truck by a forklift, the building unit 2 is lifted to a position higher than the loading platform 1, and the building unit 2 is moved in a horizontal state above the loading platform 1.

  Subsequently, when the building unit 2 is lowered toward the loading platform 1, the center of the bottom surface hole 21 a and the center C 1 of the pin portion 41 of the column projection 4 in the released state are obtained in each of the pillars 21 at the four corners. In order to match, the lower surface hole 21 a passes through the pin portion 41, and the column 21 is installed on the cover portion 311.

  Therefore, as shown in FIG. 4A, the lever portion 44 is turned in the direction of the arrow so that a part of the pin portion 41 protrudes to the side and is disposed above the lid 211 of the column 21. Switch to.

  Since the lever portion 44 operated in this way is maintained in a fixed state by the lock portion 45, the fixing is not released during transportation, and the transportation operation can be performed with peace of mind.

  Further, since the fixing and releasing can be switched by operating the lever portion 44 protruding from the side of the building unit 2, the workability is excellent, and the position of the lever portion 44 is visually checked to determine whether or not it is fixed. This can be easily confirmed.

  Further, if the fixing jig 3 (3A-3D) is first attached to the truck bed 1 and the building unit 2 is loaded thereon, the building unit 2 is suspended to attach the fixing jig. There is no need to enter underneath, and loading and unloading operations can be performed safely.

  Further, if the fixing by the column protrusion 4 is performed by arranging the side portion of the conical pin portion 41 above the lid 211 which is the lower surface of the column 21, the fixing is securely fixed by a simple mechanism. It can be performed.

  Furthermore, if the building unit 2 is fixed at the lower end by the fixing jig 3, the building unit 2 is deformed by the tightening force of the pressed rope, as in the case where the loading rope is passed over the building unit 2. No damage.

  Moreover, since the fastening bracket 33 of the fixing jig 3 can be fastened at the height of the loading platform 1, it is not necessary to perform a work at a high place as in the case where the loading rope is bridged to the building unit 2.

  Furthermore, since only the plate portion 31 is interposed between the building unit 2 and the loading platform 1, not only the curing work can be saved, but also the cargo height should be set low compared to the conventional method of laying square bars. And increase the choice of transportation routes.

  Moreover, since it is not necessary to cure the location where the rope hits with a cushioning material or the like as in the case where the packing rope is passed over the building unit 2, the height can be reduced.

  Hereinafter, Example 1 of a form different from the above-described embodiment will be described with reference to FIGS. Note that the description of the same or equivalent parts as those described in the above embodiment will be described using the same reference numerals and the same terms.

  In the fixing jig 6 described in the first embodiment, the column projection 62 provided on the plate portion 61 is different from the column projection 4 described above. Since the other configuration is the same as that of the fixing jig 3 described in the embodiment, detailed description thereof is omitted.

  The column protrusion 62 of the first embodiment is mainly configured by a frustoconical conical portion 621 and a length adjusting guide pin 623. A female screw groove 622 is provided at the upper end of the conical portion 621.

  On the other hand, a male screw groove 624 is provided below the guide pin 623. Then, the length of the columnar protrusion 62 can be adjusted by screwing the male screw groove 624 of the guide pin 623 into the female screw groove 622 of the conical portion 621.

  Next, the operation of the method for transporting the building unit 2 using the fixing jig 6 according to the first embodiment will be described with reference to FIG.

  First, a fixing jig 6 having a long columnar protrusion 62 in which a guide pin 623 is screwed into a conical portion 621 is attached to one edge side (for example, the right edge 12 side) of the truck bed 1. A fixing jig 6A having a short columnar protrusion 62A in which a short guide pin 623A is screwed into a conical portion 621 is attached to the other edge side (for example, the left edge 14 side).

  Then, the building unit 2 is lifted by the forklift F, the forklift F is brought close to the left edge 14 side of the loading platform 1 to which the short column protrusion 62A is attached, and the building unit 2 is lowered horizontally toward the loading platform 1.

  At this time, since the long columnar protrusion 62 is attached to the right edge 12 side of the loading platform 1, the long guide pin 623 can be passed through the lower surface hole 21 a of the column 21 of the building unit 2 first.

  When the guide pin 623 passes through the lower surface hole 21a, the building unit 2 is aligned. When the building unit 2 is continuously lowered, the position of the column 21 is aligned with the short column projection 62A, and thus the short guide pin 623A is passed through the lower surface hole 21a.

  That is, since the distance between the fixing jigs 6 and 6A is matched with the distance between the columns 21 and 21 of the building unit 2, the lower surface of the other can be obtained simply by passing the column protrusion 62 through the lower surface hole 21a of the one column 21. The column protrusion 62A can be easily passed through the hole 21a.

  Thus, by making the column protrusion 62 of the fixing jig 6 on one side of the building unit 2 long, the shorter column protrusion 62A can be easily passed through the lower surface hole 21a.

  Further, the elongated guide pin 623 can be easily guided to the lower surface hole 21a by bending it. Further, if the guide pins 623 and 623A are inserted into the lower surface hole 21a, the conical portion 621 can pass through the lower surface hole 21a as it is, so that the lid 211 of the column 21 is placed on the conical portion 621 and deformed. Or damage can be prevented.

  Further, by shortening the column projection 62A of the fixing jig 6A to be lowered later, even if the building unit 2 is inclined, the column does not interfere with the lid 211 with respect to the lower surface hole 21a. The projection 62A can be passed.

  The fixing jigs 6 and 6A according to the first embodiment configured as described above are configured such that guide pins 623 and 623A for adjusting the length of any length can be screwed into the upper ends of the column protrusions 62. Therefore, it is possible to easily perform the loading operation by changing the lengths of the columnar projections 62 and 62A as necessary.

  Other configurations and functions and effects are substantially the same as those of the above-described embodiment or other examples, and thus description thereof is omitted.

  Hereinafter, Example 2 of a form different from the above-described embodiment and the method of transporting a building unit of Example 1 will be described with reference to FIG. Note that the description of the same or equivalent parts as those described in the above embodiment mode or other examples will be described using the same reference numerals and the same terms.

  In Example 2, any of the fixing jigs 3, 6, 6A described in the above embodiment and examples may be used. Below, it demonstrates using the fixing jig 3 of embodiment.

  As shown in FIG. 9, the outer wall 29 is attached to only one side surface of the building unit 2A transported in the second embodiment. Accordingly, on one edge side (for example, the left edge 14 side) of the truck bed 1, the column protrusion 4 of the fixing jig 3 is installed on the center W side of the bed 1 by the thickness of the outer wall 29.

  Then, on the other edge side (for example, the right edge 12 side), the column protrusion 4 of the fixing jig 3 is installed at a position along the right edge 12 as usual. Subsequently, the building unit 2A lifted horizontally by the forklift is lowered toward the loading platform 1, and the lower surface holes 21a,... Of the columns 21,. The columns 21,... Are placed on the plate portions 31,.

  Thus, when the outer wall 29 is attached only to one side surface of the building unit 2A, the pillar protrusion 4 is installed on the center W side of the loading platform 1 by the thickness of the outer wall 29, so that the building unit 2A By making the center and the center W in the width direction of the loading platform 1 coincide with each other, it is possible to prevent the loading platform 1 from greatly protruding from one side.

  Other configurations and functions and effects are substantially the same as those of the above-described embodiment or other examples, and thus description thereof is omitted.

  The embodiment of the present invention has been described in detail above with reference to the drawings.
