[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing an external covering such as a curing sheet, a temporary scaffold, or a formwork at a construction site of a building so as to cover the periphery of the building.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer covering suitable for rearranging and a method for rearranging the same.

[0002]

2. Description of the Related Art In general, at a construction site of a building such as a building, a curing sheet is stretched on a side surface of the building for the purpose of preventing wind and rain from entering the construction site and preventing scattering of falling objects. I have. In addition, a temporary scaffold may be assembled around a building to secure a working scaffold. Further, a formwork or the like for placing concrete may be assembled on the side wall of the building. As described above, the outer covering such as the curing sheet, the scaffold, or the formwork is provided around the building under construction.

[0003] Conventionally, such outer coverings are usually gradually changed from lower to upper as the construction of the building progresses. At this time, it takes a great deal of time and effort to disassemble the outer covering and move it upward, and assemble it again. For this reason, in recent years, the outer cover is configured to be capable of being divided into a plurality of units, and when replacing the outer cover, the outer cover is divided, moved upward for each unit, and then integrated again. I try to assemble.

[0004]

However, the following problems exist in the conventional outer cover and the method of changing the outer cover as described above. That is, in order to move each unit upward when changing the unitized outer covering, it is necessary to use a tower crane or a mobile crane installed above the frame to be constructed. If a tower crane is used, the tower crane will be occupied during the work of changing the outer cover, and other work such as lifting work for building the frame and carrying in materials cannot be performed. There is a problem that hinders shortening of the construction period. On the other hand, when using a mobile crane,
There is a problem that the use of the mobile crane is restricted when the installation position of the outer covering is at a high place or when the site around the building to be constructed is narrow. In addition, when a tower crane or a mobile crane is used in this way, there is a problem in that when each unit is moved, it may interfere with the frame and damage it.

[0005] Further, even when the outer cover is unitized, it takes a long time if the unit is divided and rearranged for each unit. On the other hand, it is conceivable to shorten the time by increasing the number of cranes. However, such a method causes an increase in equipment cost, and is an effective means for solving the above problem. That is not the case. SUMMARY OF THE INVENTION The present invention has been made in consideration of the above points, and is intended to provide low-cost and easy installation and refilling of outer coverings that cover the periphery of a building, such as curing sheets, scaffolds, and formwork. It is an object of the present invention to provide an outer covering that can be made and a method of changing the outer covering.

On one surface side of the horizontal members 7, 7,..., A guide rail 10 having a vertical length of, for example, about two stories of the skeleton 1 and having an I-shaped cross section is attached in parallel with the frame 6. .

A support bracket (support member) 11 is slidably mounted on the guide rail 10 as follows. As shown in FIG. 3, the support bracket 11 is provided with sliding portions 11a, 11a which mesh with the guide rail 10 at two positions above and below the support bracket 11, and the support bracket 11 moves along the guide rail 10 so that the support bracket 11 is moved. It is configured to be vertically movable along the guide rail 10. At this time, a friction reducing material (not shown) such as Teflon resin is disposed on a sliding surface of the guide rail 10 on which the sliding portions 11a of the support bracket 11 slide. Bracket 11
The sliding resistance generated between the guide rail 10 and the guide rail 10 is reduced. Positioning holes (not shown) are formed at predetermined positions of the support bracket 11 and the guide rail 10, respectively, and the support bracket 11 is fixed to the guide rail 10 by inserting a positioning pin (not shown) here. I can do it.
Further, stopper members 10a are provided at the upper and lower ends of the guide rail 10, respectively, so that the movement stroke of the support bracket 11 is limited. In addition, holes or fixtures (not shown) provided on the guide rail 10 for fixing the stopper member 10a are formed at regular intervals, and the position of the stopper member 10a is maintained even when the floor height of the building changes. Can be easily changed.

The support bracket 11 has horizontal members 12a and 12b extending in the horizontal direction from above and below a base (one end) 11b, and extends vertically and obliquely between the horizontal members 12a and 12b. And a reinforcing member 13 attached thereto. As shown in FIG. 4, a hinge mechanism (not shown) is provided on the base 11b side and the intermediate part 11c of the support bracket 11. As a result, the support bracket 11 has its base 1

The control device (not shown) includes detection data detected by these inclination detectors and stroke meters and L / S
A stop signal is sent. The control device (not shown) controls the operation of each elevating mechanism 16 based on these data, so that the outer covering A can be raised and lowered in the vertical direction while maintaining the horizontal state. . The control device (not shown) is provided with an interlock circuit. If the inclination or the level of the outer cover A is out of a preset range, for example, a sound or light Thus, an alarm can be issued and the operation of each elevating mechanism 16 can be automatically stopped. Of course, when the operation of the elevating mechanism 16 is stopped for some reason in this way, it is needless to say that the operation can be restarted after returning to the original state. In addition to this, the control device (not shown) includes an operation mode for operating the plurality of electric chain blocks 15,
An interlock circuit for safely performing the ascending / descending operation and a circuit for controlling the speed of the chain block 15 are provided. Also, this control device
To increase the number of chain blocks 15
The power circuit is provided in advance.

Next, a method of rearranging the outer covering A having the above-described structure upward as the construction work of the frame 1 progresses will be described with reference to FIGS. As shown in FIG. 5, in a normal state, each support bracket 11 that supports the outer covering A is installed on the floor 1 a of the skeleton 1, for example, on the nth floor. In this state, the outer covering A is prevented from invading wind and rain into the construction site inside the outer covering A and being scattered by falling objects during the work, by the curing sheet 3 stretched on the outer peripheral surface thereof. It has become so. Further, on the scaffold plate 5 (see FIGS. 2 and 3) of the framework scaffold 2, an operator can perform construction work.

As the construction progresses, the floor 1 on the (n + 1) th floor
After the completion of the construction of a, when the outer cover A is to be repositioned upward, it is performed as follows.

<First Step> First, as shown in FIG. 6, the tip of the chain 14 of the elevating mechanism 16 provided on each support bracket 11 is fixed to the lower surface of the support bracket 11, and a moving pulley is provided. The hook 14a is engaged with a suspension plate (holding member) 21 formed at the lower end of the frame 6 of the outer cover A via a wire (suspension member) 20. In this state, the chain 14 is rolled up by a minute dimension in each chain block 15. Then chain 1
4 generate tension, and the shearing force applied to the positioning pins 22, 22,... Fixing the support bracket 11 and the guide rail 10 is supported by the chain 14. Then, the positioning pins 22, 22,... Are pulled out to release the fixing between the support bracket 11 and the guide rail 10. Subsequently, as shown in FIG. 7, each lifting mechanism 16 is controlled by a control device (not shown), and the chains 14 are simultaneously wound by the respective chain blocks 15. Then
The frame 6, that is, the outer covering A, rises by receiving a reaction force from the support bracket 11 fixed to the frame 1. At this time, as described above, since the support bracket 11 slides along the guide rail 10,
The frame 6 includes a support bracket 11 fixed to the frame 1.
Is guided vertically and rises vertically upward. At this time, the operation of each chain block 15 is controlled by the control device (not shown) based on detection data from an inclination detector and a stroke meter (not shown) and a stop signal from L / S. Thus, the outer cover A rises without interfering with the skeleton 1 while maintaining the horizontal state. After raising only the outer covering A by one floor in this way, as shown in FIG.
The positioning brackets 22 are fixed to the guide rails 10 by inserting the positioning pins 22, 22,.

<< Second Step >> Next, all the 18 steps shown in FIG.
Of the support brackets 11 provided at the locations, first, one support bracket 11 is rearranged as follows. As shown in FIG. 8, one end of the wire rope 23 is fixed to the upper end of the frame 6 and the fixed pulley 24 is fixed.
Attach. And the other end of the wire rope 23 is
The moving pulley 25 and the constant pulley 24 are connected to the tip of the chain 14 of the lifting mechanism 16. Then, as shown in FIG. 9, the moving pulley 25 is connected to the support bracket 11 via the auxiliary wire 26. Next, chain block 1
5, the chain 14 is wound up by a very small size, so that fixing brackets (not shown) such as anchor bolts for fixing the support bracket 11 to the floor 1a of the frame 1 and positioning pins 22, 22,... (See FIG. 8) ) Is supported by the outer covering A. In this state, the positioning pins 22, 22,.
The support bracket 11 is detached from the frame 1 by releasing the fixing between the guide rail 10 and the guide rail 10 and pulling out a fixing bracket (not shown). 4 and 9
As shown in (2), the support bracket 11 is folded in the horizontal direction so as not to interfere with the skeleton 1 when ascending. Then
As shown in FIG. 10, the chain 14 is wound up by the chain block 15, and the support bracket 11 is raised by one floor. Subsequently, as shown in FIG.
1 is extended and placed on the floor 1a on the (n + 1) th floor of the skeleton 1, and is fixed with a fixing bracket (not shown). Further, the positioning pins 22, 22 are inserted into the support bracket 11 and the guide rail 10, and these are fixed. Thereafter, the chain 14 is extended by the chain block 15, the tension of the chain 14 is relaxed, and then the wire rope 23, the fixed pulley 24, the moving pulley 25, the auxiliary wire 26, and the like are removed, so that the support bracket 11 is replaced. Is completed. In this way, while one support bracket 11 is being refilled, the outer covering A is
Supported by.

Then, the above-mentioned second step is performed in the same manner for the other support brackets 11 sequentially, and the support brackets 11 are rearranged upward one by one, and when all the support brackets 11 are rearranged, Thus, the work of changing the outer cover A is completed.

In the above-described method of changing the outer cover A, in the first step, the fixing between the outer cover A and the support bracket 11 is released, and the lifter 16 raises this by one floor. By fixing to the support bracket 11,
First, only the outer cover A was changed. Then, in the second step, the support brackets 11 are sequentially removed one by one from the skeleton 1 while releasing the fixing to the outer cover A, and the support brackets 11 are raised and lowered by one floor by the elevating mechanism 16 to be replaced. In this way, since the outer cover A can be automatically rearranged without being disassembled and divided, the work of rearranging the outer cover A can be performed easily and in a short time. In addition, since the refilling operation is performed by the elevating mechanism 16 provided on the outer cover A, there is no need to use a tower crane (not shown) provided on the frame 1 or a mobile crane. This makes it possible to use a tower crane (not shown) to perform other construction work of the skeleton 1 in parallel during the refilling work of the outer cover A, thereby shortening the construction period. it can. In addition, even in a high place or a narrow site where a mobile crane or the like cannot be used, the outer cover A can be changed. Also, the support bracket 1
When the support brackets 1 are changed, the support brackets 11 are sequentially changed one by one.
The outer cover A can be always supported by the other remaining support brackets 11 even during the first refilling operation.
Thus, there is no need to prepare a special support member or the like used only for supporting the outer cover A when the support bracket 11 is replaced.

In the above-mentioned outer covering A, the guide rail 10 and the support bracket 11
And a lifting mechanism 16. This allows
The outer cover A is normally used for the support bracket 11
And is installed on the skeleton 1 via the. When the fixing of the support bracket 11 to the guide rail 10 is released and the outer cover A is lifted by the lifting mechanism 16, the guide rail 1 is lifted.
0 is guided by the support bracket 11, whereby the outer cover A can be rearranged vertically upward. Also,
The fixing between the support bracket 11 and the guide rail 10 is released, the support bracket 11 is removed from the skeleton 1, and the support bracket 11 is repositioned by raising the support bracket 11 along the guide rail 10 by the elevating mechanism 16. be able to. In this way, in the external covering A, the refilling method can be realized, thereby facilitating the refilling operation of the external covering A and shortening the construction period. Moreover, at this time, the outer cover A can be easily and reliably rearranged vertically upward by the guide rail 10 and the support bracket 11, so that the outer cover A can be rearranged without interfering with the frame 1. It becomes possible. The support bracket 11 is configured to be foldable in two stages in the horizontal direction. Thus, when the support bracket 11 is changed, it can be changed without interfering with the frame 1. Further, the frame 6 is provided so as to extend between the upper end and the lower end of the outer covering A. This makes it possible to increase the rigidity of the outer covering A composed of the framework scaffold 6, so that the outer covering A bends and swings even when the outer covering A is integrally changed as described above. Or skeleton 1
It is possible to safely and reliably change the order without interfering with the order. In addition, the guide rail 10 is provided with stopper members 10a, 10a. This allows
When the movement stroke of the support bracket 11 is restricted and the outer cover A is changed, the support bracket 11 can be prevented from coming off the guide rail 10 by any chance. Therefore, it is possible to improve the safety of the work of changing the outer cover A. In addition, the outer cover A
Is provided with an inclination detector (not shown), a stroke meter (not shown), and a normal stop L / S (not shown). A controller (not shown) controls each of the lifting / lowering mechanisms 16 based on the detection data detected by the tilt detector, the stroke meter, and the L / S, so that the outer cover A is vertically maintained while the horizontal state is maintained. It can be raised and lowered in the direction. Thus, the outer cover A can be safely rearranged without interfering with the skeleton 1, and can be accurately and horizontally installed after the rearrangement. Therefore, every time the outer cover A is changed, it is not necessary to adjust the position by detecting the level and level of the outer cover A with, for example, a transit or the like. This also facilitates the work of changing the outer cover A. In addition, it is possible to shorten the construction period. In addition, the lifting mechanism 16 is connected to the hook 14
a, and a chain block 15 for unwinding the chain. Thereby, it becomes possible to change the outer cover A and the support bracket 11. Moreover, the lifting mechanism 16 having such a configuration has an advantage of being small in size and low in cost.

In the above embodiment, the outer cover A
Has been described using an example of changing the order one floor at a time, but it is needless to say that the change may be made at the pitch of two floors or more. Also,
When the support brackets 11 are rearranged, these are rearranged one by one. However, if it is possible to reliably support the outer cover A during the rearrangement, a plurality of support brackets may be used. 11 may be changed simultaneously. By doing so, it is a matter of course that the construction period can be further shortened. Also, after replacing the outer cover A, the support bracket 1
For example, when the outer cover A is changed, one or a plurality of support brackets 11 are fixed to the guide rails 10 when the outer cover A is changed.
, And may be lifted integrally with the outer cover A to be replaced. This also makes it possible to reduce the work period required for changing the outer cover A. Further, the support bracket 11 is configured to be foldable in two steps. However, if the support bracket 11 can be prevented from interfering with the skeleton 1 when the support bracket 11 is replaced, for example, a horizontal member may be used. 12
Other structures, such as a structure in which a and 12b rotate in a horizontal plane or a vertical plane around the base 11b of the support bracket 11, or a structure in which the horizontal members 12a and 12b can expand and contract, may be used. In the above embodiment, the elevating mechanism 16 is constituted by the chain 14 and the chain block 15. However, the elevating mechanism 16 is constituted by, for example, a hydraulic cylinder or the like which expands and contracts in the vertical direction. May be changed. By doing so, the preparation work for installing the chains 14, the wire ropes 23 and the like can be eliminated, and the work of changing the arrangement can be further facilitated. Furthermore, in the above embodiment, the frame scaffold 2 and the curing sheet 3 were used as the outer covering A to be refilled. However, other than this, of course, only the curing sheet 3, only the scaffold, or the frame of the frame 1. You may make it install and rearrange other things, such as a formwork which forms a wall or a wall surface. Even in such a case, the same effect can be obtained by applying the same configuration as described above. Further, a roof covering the entire upper surface of the skeleton 1 is provided on the upper surface of the frame scaffold 2 of the above embodiment to form an all-weather external covering, and the outer covering is similarly formed as the construction of the skeleton 1 progresses. You can also change the order. Thereby, the construction of the skeleton 1 can be performed without being affected by the weather. At this time, after replacing the outer covering provided with the roof, a scaffold may be assembled below the roof, and the scaffold may support the load of the roof. In addition, the outer covering A and the method of changing the outer covering are not limited to being applied only to the outer peripheral portion of the skeleton 1, and can be applied to the inner peripheral portion such as a shaft portion or a blow-through portion of a building. Needless to say.
