Description

  The present invention relates to a floor unit storage facility and a storage method.

  At the construction site of a building, a floor-laying method is often employed in which a beam member and a floor member are assembled in advance and then installed in the building. Further, a unit construction method in which a fireproof coating is further applied to a unit in which a beam member and a floor member are assembled, and a facility member or the like is first incorporated is also adopted. In the unit method, it is common to store the floor unit in another place after assembling the floor unit on the ground. For example, a unit member pre-assembly method and a unit member pre-assembly device for storing a plurality of floor units separated in the vertical direction so that a plurality of floor units can be stored in a narrow place are known (for example, Patent Document 1). reference).

  In addition, as a device for lifting a floor unit that has been stored separately in the vertical direction, when an upper floor unit is used and a storage space is available, a lifting unit is used to lift unit members that are sequentially lifted to the upper stage. A heavy apparatus is known (see, for example, Patent Document 2).

  However, when the unit member pre-assembly device described in Patent Document 1 and the unit member lifting device described in Patent Document 2 are combined, the floor unit is lifted when the floor unit is lifted. The work etc. which transfer to the beam for lifting occurs. Therefore, a plurality of processes are required for lifting the floor unit. For this reason, there has been a problem that hinders efficient lifting work.

  Therefore, an object of the present invention is to provide a floor unit storage facility and a storage method capable of reducing the number of steps required for lifting a floor unit and realizing efficient lifting work.

  A floor unit storage facility according to the present invention that has solved the above problems is a storage facility for storing a floor unit used for a floor portion of a building, and includes a plurality of vertical frames extending in a vertical direction, and a plurality of vertical frames. A horizontal frame spanned between the vertical frames, and a floor unit in which a storage area for storing a plurality of floor units separated in the vertical direction is set in an area surrounded by the vertical frame and the horizontal frame, and the floor unit Is installed in each of the receiving girder integrated with the floor unit until it is unloaded from the storage facility and the pair of vertical frames arranged with the storage area in between, and integrated with the floor unit stored in the storage area A girder holding member that holds the girder horizontally, a lifting device that lifts the girder integrated with the floor unit, and a girder from which the floor unit has been removed are suspended. And a girder holding member, wherein the girder holding member comprises retraction means for retreating from the movement position of the girder when lifting the girder integrated with the floor unit. .

  In the floor unit storage facility according to the present invention, the floor unit and the receiving beam supporting the floor unit are integrated until the floor unit is carried out of the storage facility. This eliminates the need to replace the floor unit with the lifting beam or return the lifting beam to a predetermined position after lifting the floor unit to the upper stage. Therefore, the number of steps required for lifting the floor unit can be reduced, and an efficient lifting work can be realized.

  Further, the receiving girder is lifted by lifting at least two hanging points by the lifting device, and the distance between the two hanging points is along the longitudinal direction of the receiving beam in the floor unit. It is shorter than the length of the direction. For this reason, the distance between the two hanging points is shortened. Therefore, the bending moment acting on the girder 30 is reduced, and the strength required for the girder 30 can be reduced.

  The girder holding member is configured such that the distance between a pair of girder holding members facing each other can be adjusted. For this reason, a variety of floor units having different spans can be stored separately in the vertical direction.

  Furthermore, it has the connection means which connects the some receiving girder integrated with the floor unit mutually in the perpendicular direction. For this reason, it is possible to lift a plurality of stages at once, and it is possible to lift a plurality of stages of floor units by carrying out one lifting operation. Therefore, efficient lifting work can be performed.

  On the other hand, the storage method of the floor unit according to the present invention that solves the above problems is a method of storing a floor unit in a storage facility that stores a floor unit used for a floor portion of a building, and is along a vertical direction. A storage area for storing a plurality of floor units spaced apart in the vertical direction and surrounded by the vertical frame and the horizontal frame is provided with a plurality of extending vertical frames and a horizontal frame spanned between the plurality of vertical frames. The storage area is arranged on each of the frame set in the area, the receiving girder integrated with the floor unit until the floor unit is unloaded from the storage facility, and the pair of vertical frames arranged across the storage area. A girder holding member that horizontally holds the girder integrated in the floor unit stored in the floor unit, a lifting device that lifts the girder integrated in the floor unit, and A lowering device that suspends the receiving girder from which the lower unit has been removed, and the receiving girder holding member retracts from the movement position of the receiving girder when lifting the girder integrated with the floor unit It is characterized by lifting the receiving girder integrated with the floor unit and suspending the receiving girder from which the floor unit has been removed.

  In the floor unit storage method according to the present invention, the receiving girder integrated with the floor unit is lifted, and at the same time, the receiving girder from which the floor unit has been removed is suspended. By repeating this process, the floor unit can be lifted to the upper stage sequentially, and the receiving girder separated from the floor unit can be suspended to the lowest stage. For this reason, it is possible to continuously lift the floor unit and manufacture the floor unit at the lowest level without waiting until all stored floor units are carried out.

  According to the floor unit storage facility and the storage method according to the present invention, the number of steps required for lifting the floor unit can be reduced, and efficient lifting work can be realized.

A through hole is formed in the pulling rod 81 in a direction along the horizontal direction. A cannula 82 is inserted into a through hole formed in the pulling rod 81 and the receiving beam 30 is supported.

  Next, a storage method using the floor unit storage facility 1 will be described. Here, an example of lifting a single floor unit 40 will be described as an example of lifting the floor unit 40. 7 to 8 are flowcharts showing the storage method according to the present invention. The floor unit storage facility 1 used in the embodiment of the storage method according to the present invention manufactures the floor unit 40 on the receiving girder 30 in the manufacturing area 13 and vertically separates the three floor units 40 in the storage area 14. Can be stored. Further, the slide arm 22 of the beam holding member 20 is configured to be horizontally movable, can be advanced to the inside, and can be retracted to the outside. In the following description, the manufacturing area 13 is referred to as the second floor, the third floor, and the fourth floor in order from the lowest floor in the storage area 14, and the top floor is referred to as the fifth floor. In addition, the position of the slide arm 22 in a state where the slide arm 22 of the receiving beam holding member 20 advances inward and holds the receiving beam 30 is referred to as a holding position, and the slide arm 22 is lifted when the receiving beam 30 is lifted. The position where the position is retracted will be referred to as the retracted position.

  As shown in FIG. 7A, three floor units 40 integrated with the receiving girder 30 are stored in the third to fifth floor areas. A step of lifting the floor unit 40 from the first floor to the second floor is performed. First, the receiving girder 30 and the plurality of small beams 41 placed on the first floor are fixed in a fixing manner as shown in FIG. 4, and the deck plate 42 is installed on the upper surface of the small beams 41. In this step, the floor unit 40 and the receiving beam 30 are integrated. Next, the pinion gear 23 (FIG. 2) of the second-girder holder member 20 is rotated clockwise to move the slide arm 22 of the receiver holder member 20 to the retracted position. Then, the receiving beam connecting member 72 provided at the tip of the wire 53 and the receiving beam 30 are connected. Subsequently, by operating the winding upper part 52 in the winding direction, the receiving girder 30 integrated with the floor unit 40 is lifted to a position higher than the height of the receiving girder holding member 20 on the second floor. Thereafter, the pinion gear 23 of the second-girder holder holding member 20 is rotated counterclockwise to move the slide arm 22 of the receiver girder holding member 20 to the holding position. Then, by operating the winding upper part 52 and unwinding the wire 53, the raised girder 30 and the floor unit 40 are placed on the slide arm 22 of the receiving girder holding member 20 returned to the holding position. Further, the floor unit 40 is manufactured by applying a fireproof coating (not shown) and attaching equipment members.

  A step of carrying out the floor unit 40 stored on the fifth floor is carried out. As shown in FIG. 7B, the floor unit 40 and the receiving beam 30 stored on the fifth floor are released from the fixed state. For example, in the case of the fixing mode as shown in FIG. 4, the tightened nut 35 (FIG. 4) is loosened so that the beam fixing member 33 can rotate around the bolt 34. Subsequently, the beam support 30 and the floor unit 40 are released from the fixed state by rotating the beam fixing member 33 and making the beam 41 movable. Next, the floor unit 40 released from the fixing with the receiving girder 30 is carried out of the storage facility 1 by a crane (not shown) provided outside the storage facility 1. At this time, as shown in FIG. 7 (b), the girder 30 remains mounted on the girder holding member 20 on the fifth floor. And the receiving beam connection member 72 provided at the front-end | tip of the wire 63 is fixed to the receiving beam 30 with which it was mounted. Thereafter, as shown in FIG. 7C, the receiving girder 30 is slightly lifted from the receiving girder holding member 20 on the fifth floor.

  A step of lifting the floor unit 40 stored on the fourth floor to the fifth floor is performed. As shown in FIG. 8A, first, the pinion gear 23 of the beam holding member 20 is rotated clockwise to move the slide arm 22 of the beam holding member 20 on the fifth floor to the retracted position. Next, the winding upper part 62 is operated in the direction of unwinding, and the receiving beam 30 connected to the receiving beam connecting member 72 provided at the tip of the wire 63 is lowered to the fourth floor. On the other hand, the upper part 52 is operated in the direction of unwinding, the receiving girder connecting member 72 provided at the tip of the wire 53 is lowered to the height of the receiving girder 30 stored on the fourth floor, and the receiving girder connecting member 72 And the receiving girder 30 are connected. Thereafter, the winding upper part 52 is operated in the direction of winding up, and the receiving girder 30 integrated with the floor unit 40 is lifted to a position higher than the height of the receiving girder holding member 20 on the fifth floor. Then, the pinion gear 23 of the beam holding member 20 is rotated counterclockwise, and the slide arm 22 of the beam holding member 20 is moved to the holding position. Then, as shown in FIG. 8B, the receiving girder 30 lifted on the slide arm 22 of the receiving girder holding member 20 which is operated in the direction of unwinding the winding upper part 52 and returned to the holding position is placed.

  A step of lifting the floor unit 40 stored on the third floor to the fourth floor is performed. As shown in FIG. 8B, first, the pinion gear 23 of the beam holding member 20 is rotated clockwise to move the slide arm 22 of the beam holding member 20 on the fourth floor to the retracted position. Next, the winding upper part 62 is operated in the unwinding direction, and the receiving beam 30 connected to the receiving beam connecting member 72 provided at the tip of the wire 63 is lowered to the third floor. On the other hand, the upper part 52 is operated in the direction of unwinding, the receiving girder connecting member 72 provided at the tip of the wire 53 is lowered to the height of the receiving girder 30 stored on the third floor, and the receiving girder connecting member 72 And the receiving girder 30 are connected. Thereafter, the winding upper part 52 is operated in the direction of winding up, and the receiving girder 30 integrated with the floor unit 40 is lifted to a position higher than the height of the receiving girder holding member 20 on the fourth floor. Then, the pinion gear 23 of the beam holding member 20 is rotated counterclockwise, and the slide arm 22 of the beam holding member 20 is moved to the holding position. Then, the receiving girder 30 lifted on the slide arm 22 of the receiving girder holding member 20 which is operated in the direction of unwinding the winding upper part 52 and returned to the holding position is placed.

  By repeating the steps shown in FIGS. 8 (a) and 8 (b), the receiving girder 30 released from the fixation with the floor unit 40 is moved to the first floor as shown in FIG. 8 (c). You can go back up. Then, the process returns to the step shown in FIG. Thereafter, the same process is repeated to perform storage using the floor unit storage facility 1.

  Further, as a method of lifting the floor unit 40, a method of lifting a plurality of floor units 40 can be used in addition to a method of lifting a single floor unit 40. In FIG. 8A, the floor unit 40 stored on the fourth floor is lifted to the fifth floor. At this time, the receiving beam 30 integrated with the floor unit 40 on the fourth floor, the receiving beam 30 integrated with the floor unit 40 on the third floor, and the receiving beam 30 integrated with the floor unit 40 on the second floor, Are connected using connecting means as shown in FIGS. 6 (a) and 6 (b).

  Then, when the upper part 52 is operated in the direction of winding up and the receiving girder 30 integrated with the fourth floor unit 40 is lifted to a position higher than the height of the fifth floor receiving girder holding member 20, At the same time, the girder 30 integrated with the floor unit 40 on the third floor is lifted to a position higher than the height of the girder holding member 20 on the fourth floor, and the girder 30 integrated with the floor unit 40 on the second floor. Is lifted to a position higher than the height of the girder holding member 20 on the third floor. Then, the pinion gears 23 of the fifth- to third-floor girder holding members 20 are rotated counterclockwise to move the slide arm 22 of the fifth- to third-floor girder holding members 20 to the holding position. Then, the girder lifted on the slide arm 22 of the girder holding member 20 on the fifth floor to the third floor which is operated in the unwinding direction of the winding upper part 52 and returned to the holding position as shown in FIG. 8C. 30 is placed.

  Thus, in the floor unit storage facility 1 according to the present embodiment, the floor unit 40 and the receiving girder 30 that supports the floor unit 40 are integrated until the floor unit 40 is unloaded from the storage facility 1. After the receiving girder 30 and the floor unit 40 are detachably fixed by the beam fixing member 33 when the floor unit 40 is manufactured, the fixing is not released until the floor unit 40 is carried out of the storage facility 1. For this reason, when the floor unit 40 is lifted, for example, a process of replacing the lifting unit with a lifting beam or returning the lifting beam to a predetermined position after lifting the floor unit 40 to the upper stage becomes unnecessary. Therefore, the number of processes required for lifting the floor unit 40 can be reduced, and efficient lifting work can be realized. Furthermore, since there is no need to prepare a lifting beam on each floor, the necessary equipment can be reduced.

  Moreover, Fig.9 (a) is a front view which shows the structure of the receiving beam 30, the beam 41, and the deck plate 42 with which the storage equipment in a prior art is equipped. In the storage facility in the prior art, since it is necessary to replace the receiving beam 30 with the lifting beam, the distance between the first lifting suspension point 31a and the second lifting suspension point 31b is the small beam 41 at both ends. It cannot be set shorter than the distance.

  On the other hand, FIG. 9B is a front view showing the configuration of the receiving beam 30, the beam 41, and the deck plate 42 provided in the storage facility 1 according to the present embodiment. According to the storage facility 1 according to the present embodiment, the floor unit 40 and the receiving girder 30 that supports the floor unit 40 are integrated until the floor unit 40 is unloaded from the storage facility 1. There is no need for a process of replacement. For this reason, since the first lifting suspension point 31a and the second lifting suspension point 31b can be set at arbitrary positions in the longitudinal direction of the receiving beam 30, the first lifting suspension point 31a and the second lifting suspension point 31b It is possible to set a short distance from the suspension point 31b. Therefore, the bending moment acting on the girder 30 is reduced, and the strength required for the girder 30 can be reduced.

  Further, as shown in FIG. 3, the girder holding member 20 is configured such that the distance between a pair of girder holding members 20 facing each other can be adjusted. For this reason, various floor units 40 having different spans can be stored in the vertical direction. Further, the advance distance of the slide arm 22 of the girder holding member 20 may be lengthened to be horizontally movable to a position corresponding to the span of the floor unit 40.

  Moreover, the floor unit storage facility 1 according to the present invention has connecting means for connecting the receiving girders 30 integrated with the floor unit 40 to each other in the vertical direction. By having such connecting means, it is possible to lift a plurality of stages at once, and it is possible to lift a plurality of stages of floor units 40 by carrying out one lifting operation. . Therefore, efficient lifting work can be performed.

  In the floor unit storage method according to the present invention, the receiving girder 30 integrated with the floor unit 40 is lifted, and at the same time, the receiving girder 30 from which the floor unit 40 has been removed is suspended. By repeating this process, it is possible to lift the floor unit 40 sequentially to the upper stage and suspend the receiving girder 30 separated from the floor unit 40 to the lowest stage. For this reason, the lifting of the floor unit 40 and the production of the floor unit 40 on the ground can be performed continuously without waiting until all the stored floor units 40 are carried out. Moreover, since the floor unit 40 can be manufactured on the ground, it is possible to eliminate the occurrence of work at high places.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. Various means can be used as means for moving the slide arm 22 in the horizontal direction. For example, as shown in FIG. 10A, the slide arm 22 is returned to the holding position using the weight of the slide arm 22 itself, and the slide arm 22 is moved horizontally using the hydraulic cylinder 91 as shown in FIG. As shown in FIG. 10 (c), the slide arm 22 is urged away from the vertical frame 11 by a spring 101 provided between the arm holding portion 21 and the substantially L-shaped slide arm 22. As shown in FIG. 10 (d), the slide arm 22 is horizontally moved by rotating the screw 111 fixed to the arm holding portion 21, and the nut 121 is rotated as shown in FIG. 10 (e). A means for horizontally moving the slide arm 22 may be used.

  In addition to the structure using the slide arm 22 movable in the horizontal direction, the girder holding member 20 converts linear motion into linear motion in a direction substantially perpendicular to the input, as shown in FIG. It is good also as a member using Scott Russell mechanism 131 which can be performed.
