The main building 1 is configured to have beams 2A to 2N provided at predetermined intervals in the height direction, main building pillars 3A to 3D arranged at four corners, walls, and the like. In particular, as shown in FIG. 2, four existing shelf columns 4A to 4D are erected in the main building 1 in one row, and the existing shelf rails are fixed at predetermined intervals in the vertical direction of the existing shelf columns 4A to 4D. At the same time, pallets are arranged to form a multi-tiered parking space. Similarly, four existing shelf columns 5A to 5D are erected on the other row side, and existing shelf rails are fixed at predetermined intervals in the vertical direction of the existing shelf columns 5A to 5D, and pallets are arranged to provide a multi-stage parking space. Is formed.

In the pallet-type mechanical parking device before replacement, a boarding surface 6 for parked vehicles is formed in the lower part of the main building 1 shown in FIG. 1, and each of the pit bottom surfaces 7 formed below the boarding surface 6 is formed. The lower ends of the existing shelf columns 4A to 4D and the existing shelf columns 5A to 5D are fixed to each other by using anchor bolts for fixing (not shown).

In the parking space of any stage shown in FIG. 2, the existing brackets 8A to 8D are fixed to the main body building beam 2B using anchor bolts (not shown), and the existing brackets 8A to 8D are used to fix the existing shelf columns 4A. ~ 4D is fixed. The pallet 10 is arranged between the existing shelf rail 9A fixed between the existing shelf columns 4A and 4C and the existing shelf rail 9B fixed between the existing shelf columns 4B and 4D.

Similarly, the existing brackets 11A to 11D are fixed to the main body building beam 2B by using anchor bolts (not shown), and the existing shelf columns 5A to 5D are fixed by using the existing brackets 11A to 11D. The pallet 13 is arranged between the existing shelf rail 12A fixed between the existing shelf columns 5A and 5C and the existing shelf rail 12B fixed between the existing shelf columns 5B and 5D. An existing lift that can be raised and lowered is arranged in the lift chamber 14 in the central portion (not shown in detail), and the pallet 10 or the pallet 13 is delivered from the existing lift.

Figure 3 is a flowchart showing the replacement facilities coating method of the pallet mechanical parking system according to an embodiment of the present invention.

In step S1, the existing pallet-type mechanical parking device in the main building 1 is disassembled, removed, and carried out. In step S2, the existing anchor bolts of the slab, the beam, and the wall of the main building 1 are diverted.

Here, it is conceivable to cut the existing anchor bolts, but during the replacement work, a great deal of vibration and noise will be generated, causing great inconvenience to the residents, and at the same time, the vibration and noise will cause a period of interruption of the construction. As a result, the replacement work period becomes longer, and the cost borne by the owner also increases. In particular, in the design of burying the anchor bolts for fixing in the pit bottom surface 7 of the existing main building 1 or the beams 2A to 2N of the main building, the sound of the burying work of the anchor bolts for fixing echoes throughout the main building 1 and resides. It causes a great deal of trouble to people. Further, when a new anchor bolt for fixing is embedded, there is a risk that a strength problem may occur because the reinforcing bars existing in the columns, beams, walls and floor of the skeleton in the existing main body building 1 are damaged.

Therefore, the existing anchor bolts used in the beams and floor of the main building 1 are used.

In step S3, the existing anchor bolts buried in the bottom surface 7 of the pit are used to fix the new H-shaped steel beam for vertical load transmission. Next, in step S4, a lift climber is used to fix the steel plate for horizontal force transmission during a new earthquake by using the existing anchor bolts embedded in the existing beam. Subsequently, in step S5, an establishment work is performed in which the lower end portion of a new shelf column or the like is fixed and established on the new H-shaped steel beam for vertical load transmission.

After that, in step S6, a lift climber is used to fix a new shelf column or the like to the steel plate for horizontal force transmission at the time of a new earthquake via a bracket. The work after step S3 described above will be specifically described with reference to the drawings.

4 and 5 are a plan view and a front view of a pit portion showing a fixing operation of a new vertical load transmission H-shaped steel beam.

As shown in FIG. 4, on the bottom surface 7 of the pit, the existing anchor bolts 18A to 18A to which the existing shelf columns 4A and 4C and the existing shelf columns 5A and 5C were used to fix the existing shelf columns 4A and 4C and the existing shelf columns 5A and 5C when the steps S1 and S2 were completed. 18D and existing anchor bolts 19A to 19D are left.

As described above, in step S3, the existing anchor bolts buried in the bottom surface 7 of the pit are used to fix the new H-shaped steel beam for vertical load transmission.

In order to divert the remaining existing anchor bolts 19A to 19D, a new H-shaped steel beam 20A for vertical load transmission extending along the lower end juxtaposition direction of the existing shelf columns 4A, 4C, 5A, 5C is arranged on the bottom surface 7 of the pit. A new H-shaped steel beam 20B for vertical load transmission extending along the juxtaposed direction of the lower ends of the existing shelf columns 4B, 4D, 5B, and 5D is arranged. The new H-shaped steel beam 20A for vertical load transmission and the new H-shaped steel beam 20B for vertical load transmission are arranged so as to face each other in a substantially parallel relationship.

In the embodiment shown in FIG. 4, it may not be possible to obtain exactly the same parts as the existing product, and when the new product is used, the width direction dimension thereof is different from that of the existing product, and the new shelf columns 14A to 14D, 15A There is a misalignment in ~ 15D. For example, when the existing shelf column 4A is replaced with the new shelf column 14A, the misalignment amount e1 occurs. However, since the new vertical load transmission H-shaped steel beam 20A has a structure that extends in the misalignment direction to support and fix a plurality of shelf columns, it is compared with the case of fixing with anchor bolts embedded in the bottom surface of the pit. Therefore, the joint position with the new shelf column 14A can be easily changed and adjusted in the longitudinal direction of the new vertical load transmission H-shaped steel beam 20A.

Since the shapes and fixing structures of the two new H-shaped steel beams 20A and 20B for vertical load transmission are symmetrical and have almost the same configuration, the fixing work of the new H-shaped steel beams 20A for vertical load transmission will be described next. To do.

The new vertical load transmission H-shaped steel beam 20A has bolt insertion holes formed in advance in the lower horizontal plane portion corresponding to the existing anchor bolts 18A to 18D and the existing anchor bolts 19A to 19D, respectively, and the upper horizontal plane portion. Reinforces the insertion holes for high-strength bolts that fix the new shelf columns 14A to 14D and the new shelf columns 15A to 15D, and the positions where the lower ends of the new shelf columns 14A to 14D and 15A to 15D will be fixed. Reinforcing portions 21A to 21D for reinforcing the space between the lower horizontal surface portion and the upper horizontal surface portion are prepared for this purpose.

When the new vertical load transmission H-shaped steel beam 20A is arranged along the existing anchor bolts 18A to 18D and the existing anchor bolts 19A to 19D, the lower horizontal of the new vertical load transmission H-shaped steel beam 20A as shown in FIG. The existing anchor bolts 18A to 18D and the existing anchor bolts 19A to 19D can be inserted into the bolt insertion holes formed on the surface portion.

FIG. 6 is an enlarged view of a main part showing the vicinity of the existing anchor bolts 18A and 18B of the pit part shown in FIG.

When the new vertical load transmission H-shaped steel beam 20A is arranged on the bottom surface 7 of the pit, the existing mortar or the new mortar 22 is interposed. Since each bolt insertion hole formed in the new vertical load transmission H-shaped steel beam 20A is a stupid hole larger than the diameter of the existing anchor bolt, the existing anchor bolts 18A and 18B can be easily inserted. be able to. Next, while adjusting the position of the new H-shaped steel beam 20A for vertical load transmission on the bottom surface 7 of the pit, the square washers 23A and 23B are inserted into the upper ends of the existing anchor bolts 18A and 18B, and the nuts 24A and 24B are screwed into the pit. A new H-shaped steel beam 20A for vertical load transmission is fixed on the bottom surface 7. After that, the square washers 23A and 23B are welded to the new H-shaped steel beam 20A for vertical load transmission.

7 and 8 are plan views of the new vertical load transmission H-shaped steel beam 20A shown in FIG. 5 along lines BB and CC.

FIG. 7 shows a state in which the new vertical load transmission H-shaped steel beam 20A is mounted on the existing anchor bolts 18A to 18D and the existing anchor bolts 19A to 19D. FIG. 8 shows a state in which the lower ends of the new shelf columns 14A and 14C and the new shelf columns 15A and 15C are fixed to the upper surface side of the new vertical load transmission H-shaped steel beam 20A.

Although not shown, the new H-shaped steel beam 20A for vertical load transmission is also fixed to the bottom surface 7 of the pit using other existing anchor bolts, and the new H-shaped steel beam 20B for vertical load transmission is also the same. It is fixed to the bottom surface 7 of the pit.

In this way, since the existing anchor bolts 18A to 18D and 19A to 19D are diverted to the bottom surface 7 of the pit without providing new anchor bolts for fixing, the sound of the work for burying the anchor bolts for fixing is heard in the main building 1. It does not cause a great deal of trouble to the residents. Further, by newly burying the anchor bolts for fixing, the reinforcing bars existing in the floor of the skeleton in the existing main body building 1 are not damaged, and a strength problem does not occur.

It should be noted that FIGS. 4 to 6 and 8 show a state in which the lower ends of the newly installed shelf columns 14A to 14D and 15A to 15D are connected to the new H-shaped steel beams 20A and 20B for vertical load transmission. The work of fixing the lower ends of the newly installed shelf columns 14A to 14D and 15A to 15D to the new H-shaped steel beam 20A for vertical load transmission is performed in step S5 described later.

Next, in step S4, the lift climber is used to fix the steel plate for horizontal force transmission during a new earthquake using the existing anchor bolts buried in the beams 2A to 2N of the main building 1.

FIG. 9 is a cross-sectional view of a position corresponding to the beam 2B showing the fixing work of the horizontal force transmission steel plate at the time of a new earthquake.

Existing anchor bolts 25A to 25D and 26A to 26D are provided on the beam 2B for fixing the existing brackets 8A to 8D and 11A to 11D shown in FIG. 2, and are left in the stage of step S2. Using these existing anchor bolts 25A to 25D and 26A to 26D, in step S4, a pair of plate-shaped new steel plates 27B for horizontal force transmission during an earthquake, which are arranged substantially horizontally on the inner surface side of the beam 2B, are fixed. There is.

Since the configuration of the pair of new steel sheets 27B for transmitting horizontal force during an earthquake is the same, the left steel sheet 27B for transmitting horizontal force during a new earthquake in FIG. 9 will be described here.

FIG. 10 is an enlarged plan view showing the vicinity of the existing anchor bolts 25A and 25B in FIG.

The steel plate 27B for horizontal force transmission during a new earthquake is used to attach bolt insertion holes formed in advance corresponding to the existing anchor bolts 25A to 25D and the existing anchor bolts 26A to 26D, and new brackets 28A to 28D described later. It is prepared as if the screw holes to be used were formed.

When the steel plate 27B for horizontal force transmission during a new earthquake is arranged on the inner surface side of the beam 2B, each bolt insertion hole formed in the steel plate 27B for horizontal force transmission during a new earthquake is a stupid hole larger than the diameter of the existing anchor bolt. Therefore, the existing anchor bolts 25A and 25B can be easily inserted. Next, while adjusting the position of the steel plate 27B for horizontal force transmission during a new earthquake with respect to the beam 2B, the square washers 29A and 29B are inserted into the upper ends of the existing anchor bolts 25A and 25B, and the nuts 30A and 30B are screwed into the beam 2B for a new earthquake. The steel plate 27B for horizontal force transmission is fixed. After that, the square washers 29A and 29B are welded to the steel plate 27B for horizontal force transmission during a new earthquake.

In this way, in the beam 2B, the existing anchor bolts 25A to 25D and 26A to 26D are diverted without providing new anchor bolts for fixing, so that the sound of the burying work of the anchor bolts for fixing is heard in the main building 1. It reverberates throughout and does not cause great inconvenience to residents. Further, by newly burying the anchor bolts for fixing, the reinforcing bars existing in the floor of the skeleton in the existing main body building 1 are not damaged, and a strength problem does not occur.

Although FIGS. 9 and 10 show a state in which the intermediate portion of the new shelf columns 14A, 14C, 15A, and 15C in the longitudinal direction is supported by the new horizontal force transmission steel plate 27B during an earthquake, the new shelf is actually installed. The work of fixing the intermediate portions of the columns 14A, 14C, 15A, and 15C in the longitudinal direction to the steel plate 27B for horizontal force transmission during a new earthquake is performed in step S6 described later.

FIG. 11 is a cross-sectional view showing a pallet-type machine parking device in a state where the fixing work of step S4 is completed.

The above-mentioned fixing work of the new earthquake horizontal force transmission steel plate 27B has described the beam 2B, but similarly for the other beams, the new earthquake horizontal force transmission steel plates 27A, 27C to 27N are used with existing anchor bolts. Fix it. When the fixing work of the horizontal force transmission steel plates 27A to 27N at the time of a new earthquake is completed for all the beams 2A to 2N, it becomes as shown in FIG.

In the following step S5, the establishment work is performed in which the lower end portions of the new shelf columns and the like are fixed and established on the new H-shaped steel beams 20A and 20B for vertical load transmission.

In particular, as shown in FIG. 6, the new vertical load transmission H-shaped steel beam 20A is formed with bolt insertion holes at positions predetermined in the longitudinal direction thereof, and the bolt insertion holes and the new shelf column 14A are formed. The new shelf column 14A is mounted on the new H-shaped steel beam 20A for vertical load transmission while aligning with the bolt insertion hole of the base plate 31 integrally formed at the lower end of the above, and in the matching bolt insertion hole. The high-strength bolt 32 is inserted and tightened and fixed with the nut 33.

In the same new H-shaped steel beam 20A for vertical load transmission, as shown in FIGS. 4 and 5, the base plate at the lower end of the new shelf column 14A, the new shelf column 14C, the new shelf column 15A, and the new shelf column 15C is similarly used. It is fixed to and established. Similarly, in the new vertical load transmission H-shaped steel beam 20B, as shown in FIG. 4, the lower ends of the new shelf column 14B, the new shelf column 14D, the new shelf column 15B, and the new shelf column 15D are similarly fixed. It is being established.

Since the lower ends of the new shelf columns 14A to 14D and the new shelf columns 15A to 15D are fixed to the new vertical load transmission H-shaped steel beams 20A and 20B arranged on the bottom surface 7 of the pit in this way, the new shelf columns 14A, New vertical load transmission H-shaped steel beam 20A, which is a structure with a larger area than the case where the lower ends of 14C and the new shelf columns 15A and 15C are directly fixed to the bottom surface 7 of the pit using anchor bolts for fixing. Therefore, the load can be easily received, and the load sharing in the vertical direction is reduced. Moreover, in the horizontal direction of the new vertical load transmission H-shaped steel beams 20A and 20B, since they are fixed by a plurality of existing anchor bolts 18A to 18D and existing anchor bolts 19A to 19D, the load point cannot be changed. Absent.

After that, in step S6, a lift climber is used to fix the new shelf columns 14A to 14D and the new shelf columns 15A to 15D to the steel plates 27A to 27N for horizontal force transmission during a new earthquake with brackets.

In particular, as shown in FIG. 10, the steel plate 27B for horizontal force transmission during a new earthquake is formed with a bolt insertion hole at a position predetermined in the longitudinal direction thereof, and the bolt insertion hole and the end of the new bracket 34 are formed. The base plate 34 of the new bracket 28B is fixed to the steel plate 27B for horizontal force transmission during a new earthquake with a new tap bolt 35 while aligning with the bolt insertion hole of the base plate 35 integrally formed in the portion. If the bolt insertion hole of the base plate 34 is made a long hole, the position can be easily adjusted. After that, the new shelf column 28B is fixed to the other end side of the new bracket 28B.

As shown in FIG. 9, new shelf columns 14A, new shelf columns 14C, new shelf columns 15A, and new shelf columns 15C are supported by new brackets 28A to 28D on the new earthquake horizontal force transmission steel plate 27B on the same side. Has been done. Similarly, for the other steel plate 27B for horizontal force transmission during a new earthquake arranged on the right side in the figure, the same new brackets 28A to 28D are used for the new shelf column 14B, the new shelf column 14D, and the new shelf column 15B. , The new shelf pillar 15D is supported. Similarly, the new shelf columns 14A to 14D and the new shelf columns 15A to 15D are also supported by the steel plates 27A and 27C to 27N for transmitting horizontal force during a new earthquake in the other stages.

The new shelf columns 14A to 14D and the new shelf columns 15A to 15D supported by the new vertical load transmission H-shaped steel beams 20A and 20B arranged on the bottom surface 7 of the pit in this way have their respective beams 2A in the middle portion in the longitudinal direction. The existing anchor bolts 25A to 25N for fixing are diverted to ~ 2N and fixed to the steel plates 27A to 27N for horizontal force transmission during a new earthquake via new brackets 28A to 28D, respectively.

For this reason, the horizontal force transmission during a new earthquake, which is a structure having a larger area than the case where the intermediate portions of the new shelf columns 14A to 14D and the new shelf columns 15A to 15D in the longitudinal direction are directly fixed by the anchor bolts for fixing. It can be easily supported and fixed by the steel plates 27A to 27N, and the strength in the horizontal direction at the time of an earthquake can be increased. Further, in the horizontal direction of the horizontal force transmission steel plates 27A to 27N at the time of a new earthquake, since they are fixed by a plurality of existing anchor bolts 25A to 25D and existing anchor bolts 26A to 26D, the load point is not changed. ..

Although detailed illustration is omitted, after that, the shelf rails of both rows are fixed at predetermined intervals in the longitudinal direction of the new shelf columns 14A to 14D and the new shelf columns 15A to 15D, and as shown in FIG. A pallet is arranged on each shelf rail to form a parking space for storing a parked vehicle. The elevating lift that conveys the pallets carrying the parked vehicle from the boarding surface 6 shown in FIG. 1 to each parking space is configured in the space between the pallets 10 and 13 in both rows as shown in FIG. Although not shown, the guide rail that guides the lift is also incorporated as a new product as in the past. This guide rail can be fixed to the central shelf columns 14C, 14D, 15A, 15B shown in FIG. 4, fixed to the new vertical load transmission H-shaped steel beams 20A, 20B shown in FIG. 4, and further. It can be fixed to the new earthquake horizontal force transmission steel plates 27A to 27N shown in FIG.

In the above-described embodiment, the existing anchor bolts 18A to 18D and 19A to 19D are diverted for fixing the new vertical load transmission H-shaped steel beams 20A and 20B, and the existing anchor bolts 25A to 25D and 26A to 26D are used. All of the above are diverted for fixing the horizontal force transmission steel plates 27A to 27N during a new earthquake, but the present invention is not limited to this. If sufficient strength can be obtained, for example, in FIG. 6, some existing anchor bolts 18A are not diverted for fixing, and the square washer 23A is not welded, or in FIG. 10, some existing anchor bolts are not welded. It is also possible to use the 25A for fixing and not to weld the square washer 29A.

Further, in the present embodiment described above, is used a flat new seismic horizontal force transmitting steel plate 27a to 27n, it is possible to obtain the same effect by using a dogleg steel plate. Furthermore, although it has been explained that new anchor bolts will not be buried, it does not limit the burial of construction anchor bolts and does not exclude the burial of additional new anchor bolts.
