DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the construction of buildings
The present invention relates to a climbing type elevating device for elevating a temporary stage or the like.

[0002]

2. Description of the Related Art The present inventors have designated reference number H02-0446.
In -A, a temporary stage S having a climbing device mounted thereon, which is supported by an end of a beam protruding from a main pillar and is mounted between a floor set on a roof floor and a top floor, which is finally a main beam, is provided. After assembling the members for one layer by the construction equipment attached to the stage, the temporary stage is raised through the climbing device, and the members of the required number of floors are assembled. A construction method of a building that is connected to a pillar as a beam on the top floor is proposed.

[0003] As shown in FIGS. 10 and 11, the climbing device includes a pawl L2 mounted on a rod L to which a ratchet L1 is attached and meshing with the ratchet L1.
The temporary stage S is lifted by pushing up the rod through the pawl L2 and the ratchet L1 by the jacking system J having the above, so that the jacking system J relatively lowers, and by the time of the next climbing. It is necessary to rearrange the receiving beam M that supports the jacking system J by raising J.

[0004] In addition, the jacking system used in the lift-up method or the like also needs to be re-arranged after a certain distance.

[0005]

The relocation of the climbing device affects other work, adversely affects the construction period and economy, and is a major network in increasing the automation rate of building construction. Becomes The present invention has been proposed in view of the problems of the prior art described above, and its object is to eliminate self-climbing of machines, save labor, improve economy, and improve self-climbing that can shorten the construction period. The point is to provide a device.

[0006]

In order to achieve the above object, a climbing type lifting apparatus according to the present invention has an endless chain spanned between a driving sprocket mounted on upper and lower ends of a beam and a driven sprocket. The column is provided with a continuous projection that meshes with the chain at a supporting point of the climbing device, and the endless chain link plate pressing roller is mounted on the beam.

[0007]

Since the climbing type elevating device according to the present invention is constructed as described above, the endless chain bridged between the driving sprocket mounted on the upper and lower ends of the beam and the driven sprocket is mounted on the pillar. The endless chain is meshed with the continuous projection by meshing with the continuous projection provided at the climbing device support point portion and by pressing the link plate of the endless chain by the pressure roller mounted on the beam. Even if the climbing device is loaded without load, it does not fall off, and the climbing device is smoothly and continuously raised by winding the endless chain between the sprockets.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS.
A climbing type elevating device according to the present invention, which meshes with a rack described below, attached to a necessary portion of the main column C is mounted, and the temporary stage S climbs in the order of FIGS. 7 to 8 and FIG. The work machine W travels on the upper surface and the lower surface of the stage S to carry out operations such as carrying, attaching, and joining members.

FIG. 1 to FIG. 4 show a use state of the climbing type elevating device. Two climbing type elevating devices K fixed by a receiving object 1 are arranged on a temporary stage S so as to face each other with a column C interposed therebetween. Is established. 2 is a lower drive sprocket, 3 is an upper driven sprocket, and an endless chain 4 bridged between the two sprockets 2 and 3 is temporarily attached to a beam end 5 projecting from a column C. 6 is engaged with a rack 7 which constitutes the continuous projection provided on
The metal support 6 is attached to the beam end 5 by a bolt 13.

FIGS. 5 and 6 show details of the climbing type elevating device. A beam 8 connects between the two sprockets 2 and 3 and has sufficient rigidity and strength to press the chain 4 against the supporting hardware 6. A link plate pressing roller 10 for pressing the straight portion inside the link plate 9 of the chain 4 against the beam 8 is attached at a slightly smaller interval than the interval between the rollers 11 of the chain 4. It is arranged so that it may be pressed smoothly smoothly.

The rack 7 is a roller 11 of the chain 4.
These are continuous projections having a shape and strength capable of safely supporting the load of the temporary stage S, and which are well-engaged. 1 in the figure
Numeral 2 is a roller for changing the direction of the chain 4 for disposing the climbing device K so as to prevent the racks 7 from coming into contact with the sprockets 2 and 3 and disposed near the two sprockets 2 and 3.

Since the two climbing devices K are fixed to the temporary stage S by the receiving object 1, the chains 4 can be maintained at a constant interval via the beam 8 as described above. The chain 4 of the pair of climbing devices K and the rack 7 attached to the beam end 5 are accurately and reasonably engaged with each other, and do not fall off even if the load of the temporary stage S is applied.

In FIG. 1, when the motor 14 is driven, the sprocket 2 is driven through the reduction gear 15, the gear 15 and a chain belt 16 which is bridged over the driving sprocket 2.
Power is transmitted to the chain 4 and the chain 4 is rotated, whereby a pulling force acts on the chain 4 and the climbing device K rises to move the temporary stage S
Also rises. FIG. 3 shows a position where the climbing device K has risen to the middle of the floor. The rack 7 on the upper floor with which the chain 4 is to be meshed is positioned in the position shown in FIG. It is smoothly engaged.

When the construction of the required floor is completed in this way, the temporary stage S is raised to the next floor, and the above operation is repeated to carry out the construction up to the predetermined floor. FIG.
Is a plan view showing the relationship between the temporary stage S, the climbing device K, and the column C in a plan view. When the climbing is completed and the work machine W is working, the receiving beam 17 is connected to the beam end 5 for safety. The apparatus is pulled upward to support the apparatus, and at the time of climbing, the receiving beam is drawn into the temporary stage S as shown at 17 '.

[0015]

According to the climbing type elevating device according to the present invention, the driving sprocket and the driven sprocket mounted on the upper and lower ends of the beam and the endless chain are bridged, and the continuous projection meshing with the chain is climbed on the pillar. Provided in the device support portion, further by the endless chain link plate pressure roller is mounted on the beam, the climbing type elevating device becomes an endless track type elevating device, it is not necessary to change the rearrangement, and the The chain drive sprocket, combined with its ability to be easily driven directly by a motor, is extremely advantageous for automatic control, and can shorten the construction period and improve the economic efficiency.
