Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction apparatus and a construction method capable of reducing required performance required for a climbing mechanism for moving a work stage up and down.

[0002]

2. Description of the Related Art In recent years, automation and efficiency of construction work for high-rise / super-high-rise buildings have been promoted. For example, a construction apparatus using a work stage called a hat truss and a construction method using this apparatus are known (for example, JP-A-6-185124). With this kind of construction equipment,
While the work stage is supported by posts that are provided integrally with it, while performing construction work on the floor to be constructed immediately below the work stage using various automatic work machines equipped with this work stage, This work stage is raised sequentially with the posts, so that the construction work of the building is advanced from the lower layer to the upper layer of the building. In particular, when raising the work stage, the climbing mechanism is set on the beam that composes the building, and the climbing mechanism is driven by the supporting reaction force of the beam to raise the post. I was trying to raise the stage.

[0003]

By the way, in the above-mentioned conventional construction apparatus in which the post integrated with the working stage is installed on the beam, when the working stage is raised by the climbing mechanism, The post had to be raised with it. Such a device configuration
The operating method was adopted because the construction work of the building gradually progresses to the upper floor, and the beams that support the posts are repeatedly moved from the lower one to the upper one. Therefore, it is supposed that it is reasonable to move only the climbing mechanism installed on the beam. For this reason, the climbing mechanism is detachable from the post, while the post and the work stage are integrally fixed.

However, in such an apparatus structure, as described above, the climbing mechanism needs to lift and raise the post in addition to the weight of the working stage, and therefore the climbing mechanism must be lifted. It has a fairly high performance as a climbing mechanism
I had to use a large capacity one. Further, this also raises a problem of increasing the cost of the construction device.

The present invention was devised in view of the conventional problems, and an object of the present invention is to provide a construction apparatus and a construction method capable of reducing the required performance required for a climbing mechanism for raising and lowering a work stage. And

[0006]

A construction apparatus according to the present invention is provided with a construction work machine, a work stage arranged above a floor to be constructed, and a post installed below the floor to be constructed. A post that is detachably installed on the floor and is integrally provided on the work stage and a post that supports the work stage, and raises the work stage with respect to the post so that the work target floor can be raised and lowered. A climbing mechanism for moving the work stage and the post relative to each other in order to move the post to the upper floor and raise the post with respect to the work stage to move the post installation floor to the upper floor; It is characterized by having.

In the construction method according to the present invention, the construction work machine is provided, and the work stage is arranged above the construction target floor and the post installation floor which is located below the construction target floor is detachable. And a climbing mechanism that is provided integrally with the working stage and that vertically moves the working stage and the post, the working stage being installed on the working stage. In order to advance the construction work by the construction work machine upward, the climbing mechanism raises and lowers the work stage relative to the post, and the step of moving the construction target floor to an upper floor, In order to increase the height position of the post, the climbing mechanism lowers the work stage to perform the construction. In a state of being supported on the elephant floor, raising the post with respect to the working stage, and repeating the step of transferring the post-installation floor above the floor.

In the state where the working stage 7 is statically supported by the post 6, the lock pins 18 and 19 of both the upper lock device 17 and the lower lock device 15 are engaged with the post 6.

First, a case where the working stage 7 is raised relative to the post 6 will be described with reference to FIG.
As shown in (a), first, the lock pin 19 of the upper lock device 17 is disengaged from the post 6 [see (a)], and the weight of the working stage 7 is supported by the post 6 via the lower lock device 15. In this state, the upper lock device 17 can be moved. Next, as shown in FIG. 3B, the telescopic cylinder device 16 is extended and the upper lock device 17 is raised. Subsequently, the lock pin 19 of the upper lock device 17 is engaged with the post 6 [see (b)], and the work stage 7 can be hung on the post 6 via the upper lock device 17, and the lower lock is performed. The lock pin 18 of the device 15 is disengaged from the post 6 [see (C)]. In this way, with the lower lock device 15 movable this time, the telescopic cylinder device 16 is contracted and the lower lock device 15 is pulled up, as shown in FIG. 3C. Along with this pulling up, the working stage 7 rises with respect to the post 6.

Finally, the lock pin 1 of the lower lock device 15
When 8 is engaged with the post 6 [see (d)], the work stage 7 moves up by one stroke of the telescopic cylinder device 16 to return to the state of FIG. 3 (a), and the above operation is repeated. The work stage 7 can be sequentially raised with respect to the post 6. Of course, the work stage 7 can be lowered by performing the opposite operation.
Particularly, in the present embodiment, by disposing the upper lock device 17 on the work stage 7 and fixing the lower lock device 15 below the work stage 7 via the bracket 14, the work lock Although the climbing mechanism 13 in the form of raising the stage 7 has been described as an example, the upper locking device 17 is fixed below the working stage 7 via the bracket 14, and the lower locking device 15 is set to the telescopic cylinder device 16.
Needless to say, the climbing mechanism 13 may be fixed to the lower portion of the work stage 7 to push up the work stage 7.

On the other hand, the case of raising the post 6 relative to the work stage 7 will be described. In this case, the work stage 7 is temporarily placed on the construction target floor F in advance. Therefore, only the weight of the post 6 acts on the climbing mechanism 13. As shown in FIG. 4A, first, the lock pin 18 of the lower lock device 15 is disengaged from the post 6 [see (e)], and the upper lock device 17 is released.
Can be moved while the post 6 is suspended. Next, as shown in FIG. 4B, the telescopic cylinder device 16 is extended and the upper lock device 17 is pushed up. With this push-up, the post 6 rises with respect to the work stage 7. Subsequently, the lock pin 18 of the lower lock device 15 is engaged with the post 6 [see (f)], and the post 6 is suspended by the lower lock device 15 this time.
The lock pin 19 of is removed from the post 6 [see (G)]. With the upper lock device 17 thus movable, the telescopic cylinder device 16 is contracted to pull down the upper lock device 17, as shown in FIG. 4C.

Finally, the lock pin 1 of the upper lock device 17
When 9 is engaged with the post 6 [see (h)], the post 6 moves up by one stroke of the telescopic cylinder device 16 and the post 6 is moved to the position shown in FIG.
By returning to the state of (a) and repeating the above operation, the post 6 can be sequentially raised with respect to the work stage 7. Of course, the post 6 can be lowered by performing the opposite operation.

By providing the working stage 7 with the climbing mechanism 13 having the above-described functions, both the working stage 7 and the post 6 are relatively moved up and down, and the working stage 7 is sequentially moved upward. As a result, the construction target floor F for constructing the outer peripheral frame 4 can be moved upward and the construction in the height direction of the core 1 can be promoted, and the building 5 can be constructed sequentially in the height direction. be able to.

Further, in the present embodiment, the work stage is arranged above the construction target floor F and has the construction work zone 10 for constructing the outer peripheral frame 4 on the construction target floor F below the construction work zone 10. A preceding work zone 11 for constructing the core 1 which is a work place at a high place above the construction target floor F, which is higher in height than the work stage 7, is provided on the work piece 7. The working stage 7 is located between the core 1 that is constructed in advance and has a high height position, and the construction target floor F that is constructed in a subsequent position and has a low height position,
The height between the construction target floor F and the core 1 is relatively low, and the height position of the construction site where the core 1 is constructed is relatively low as compared with the case where the construction target floor F is used as a reference. It is made to become.

Further, as shown in FIG. 2, the working stage 7 is adjacent to the core 1 as a preceding working position higher than the working stage 7, that is, the through hole of the working stage 7 in the illustrated example. It surrounds the core 1 through 8. A rolling roller 20 as a horizontal force supporting means for supporting a horizontal force acting on the work stage 7 with the core 1 is movably provided on the work stage 7 with respect to the core 1. To be That is, the rolling roller 2
0 is rotated vertically in accordance with the ascending / descending direction of the working stage 7 with respect to the core 1 so as not to interfere with at least the lifting / lowering operation of the working stage 7 by the climbing mechanism 13. It is designed to drive to.

In the illustrated example, the rolling rollers 20 are arranged at appropriate intervals around the through hole 8 around the core 1 so as to be able to support a horizontal force from any horizontal direction. It is set up. The rolling roller 20 is interposed between the work stage 7 and the core 1,
A supporting reaction force is applied to the core 1 to prevent the work stage 7 from swinging in the horizontal direction due to an external force such as seismic force or wind force.

Next, a construction method using the construction apparatus according to this embodiment will be described. In FIG. 1, a building 5 composed of a peripheral frame 4 and a core 1 is constructed in advance so that the core 1 is constructed so that the height position of the core 1 is higher than the height position of the peripheral frame 4. The construction of is shown. The work stage 7 is supported via a climbing mechanism 13 at a position lower than the height position of the core 1 above the construction target floor F of the outer peripheral frame 4 by a post 6 that is detachably provided on the post installation floor P. ing. In this work stage 7, the material carried in by using the lifting crane 9 is used to construct the outer peripheral frame 4 of the construction target floor F by the construction work machine in the construction work zone 10 and the core construction in the preceding work zone 11. Depending on the device
The core 1 is built simultaneously with the outer frame 4.

When the construction of the construction target floor F and the core 1 portion is completed, the climbing mechanism 13 is used to move the working stage 7 to the next upper floor. In the illustrated example, the post 6 is set to a length that can raise the work stage 7 by 3 floors,
In FIG. 5, two-step operation (L1, L
2) shows a state in which the work stage 7 is raised by 3 floors from the state of FIG. Next, as shown in FIG. 6, in order to move the post installation floor P to the upper floor, the posts 6 separated from the post installation floor P are installed.
Is raised by the climbing mechanism 13 (L3).
At this time, the work stage 7 is previously lowered by the climbing mechanism 13 onto the construction target floor F immediately below (D) and temporarily placed. In this state, the posts 6 are raised by three floors, and the new upper floor is set as the post installation floor P. Thereafter, as shown in FIG. 7, the work stage 7 temporarily placed on the construction target floor F is lifted along the post 6 by the climbing mechanism 13 (L4), and is located above the construction target floor F from the height position of the core 1. By returning to the state of FIG. 1 by arranging it at a lower height position, the building 5 can be successively constructed upward by repeating this.

Particularly in this embodiment, the climbing mechanism 13 is integrally provided on the working stage 7 without being installed on the floor, and the post 6 is erected on the floor. , Climbing mechanism 13
Need only bear the weight of the work stage 7 when the work stage 7 is moved up and down, and only the weight of the post 6 when the post 6 is raised. The capacity and required performance can be reduced as compared with the case of carrying weight and lifting. Therefore, the equipment cost and the running cost of the climbing mechanism 13 and by extension, the construction apparatus can be reduced.

Further, the horizontal external force acting on the working stage 7 is received by the rolling roller 20 acting as a supporting reaction force on the core 1, and the rolling of the working stage 7 can be prevented. The rolling roller 20 is used for the work stage 7
Can also function as a guide when moving up and down with respect to the core 1.

On the work stage 7, the floor F to be constructed, which is higher than the work stage 7 in height,
Since the preceding work zone 11 for constructing the core 1 which is a high-place construction site above is provided, the height position of the construction site where the core 1 is constructed is not the floor F to be constructed but the height of the working stage 7. With the position as the reference, the height becomes relatively low, work in high places can be eliminated, and construction safety can be improved. Further, since the preceding work zone 11 also rises as the work stage 7 rises, the outer peripheral frame 4 of the construction target floor F and the core 1 can be simultaneously constructed, and the formwork and work of the preceding work zone 11 can be performed. It is possible to greatly simplify the lifting device for the core building device, which is used for changing scaffolding and the like.

[0026]

In summary, according to the construction apparatus and the construction method of the present invention, the required performance of the climbing mechanism for moving the work stage up and down can be reduced, and the cost of the construction apparatus can be reduced. be able to.
