DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for hanging an outer wall curtain wall in which an outer wall curtain wall, particularly a spandrel type curtain wall, can be efficiently and safely mounted and installed in an outer wall curtain wall method. .

[0002]

2. Description of the Related Art In a conventional outer wall curtain wall construction method, unit panels of an outer wall curtain wall (hereinafter simply referred to as "curtain wall") are lifted one by one by a tower crane and transported to a predetermined mounting position of a structure. . When the installation of one of the curtain walls is completed, another curtain wall is again lifted using the tower crane, and the curtain wall is repeatedly transported to the adjacent mounting location and mounted.

[0003]

However, in such a conventional curtain wall suspension method,
Work efficiency is poor because it is lifted and mounted one by one with a tower crane. Further, if the mounting member such as the mounting bolt is mistakenly dropped when the curtain wall is mounted on the structure, the fall cannot be received unless a curing wire mesh is installed outside the curtain wall. Further, there is another problem that the curtain wall being lifted is plate-like and easily winded by the wind, so that it cannot be constructed in a strong wind or the like.

Accordingly, the present invention has been made in view of such a conventional problem, and a time schedule can be shortened by hanging a plurality of curtain walls together and attaching them to the structure one by one. Another object of the present invention is to provide a highly efficient curtain wall suspension method and apparatus which are hardly affected by wind and have high safety.

[0005]

In order to achieve the above object, a curtain wall hanging method according to the present invention comprises a plurality of curtain walls suspended in parallel in a hanging unit and fixed to a steady state. Lift the unit to the designated curtain wall attachment point of the structure,
Then, while maintaining the balance of the unit by moving the balance maintaining means as needed, the curtain wall is transported toward the structure by the hanging / sending means, hung at the mounting location, and attached to the structure. It is characterized by the following.

A curtain wall hanging device according to the present invention comprises: a hanging unit for hanging and sending a curtain wall to a hanging unit; and a hanging unit which is moved in a transport direction of the hanging and sending unit. And a balance maintaining means for maintaining a balance between the two. The hanging unit may be provided with a steadying means for the suspended outer wall curtain wall. Further, the lower frame and the upper frame can be detached to be detachable.

[0007] The hanging / sending means may comprise a plurality of self-propelled hoists for suspending and conveying the outer wall curtain wall, and a linear beam on which the self-propelled hoist travels. Alternatively, it may be provided with a plurality of hoists for suspending and transporting the outer wall curtain wall and a circulation rail for guiding the running of the hoist and circulating in the front-rear direction.

Further, the balance maintaining means may be one which includes a self-propelled balance weight which is movable in the front and rear direction of the unit hanging in response to movement of the suspended load. Alternatively, a hanging wire length varying device that adjusts the length of any of the hanging wires before and after the hanging unit according to the movement of the suspended load may be provided. Also,
The steadying means may include a guide arm rotatable from a holding position for holding both sides of each curtain wall suspended in the suspension unit to a release position thereof. Alternatively, it may be provided with a pad member to be pressed against the lower surface of each curtain wall suspended in the suspension unit, and a lifting device for the pad member. In addition, stand both ends
It is made up of connecting brackets

The curtain wall hanging device of the present invention is provided with a horizontal curing shelf which projects forward from the curtain wall sending-out floor of the hanging unit to prevent the curtain wall mounting member from falling. It can be.

[0010]

A plurality of curtain walls are mounted on a curtain wall hanging unit by means of hanging and sending out, and are lifted at once by a lifting device such as a tower crane and transported to a predetermined mounting location. It takes only a fraction of the process of lifting and lowering the tower crane for each piece, and the higher the level of the structure, the shorter the construction time schedule.

Further, since a plurality of curtain walls are lifted at the same time, the curtain walls have a heavy weight and are less likely to be swept by the wind as compared with a case where each curtain wall is lifted one by one. Once it is lifted to the specified mounting point of the structure, one of the curtain walls suspended by the hanging / sending means is sent out to the mounting point,
Attach to the structure with the hands of the workers. If the hanging unit tilts due to the movement of the center of gravity when the curtain wall is fed, the hanging unit is balanced and maintained in a horizontal posture by the balance maintaining means. When the curtain wall in the hanging unit swings back and forth, the curtain wall is fixed by the steadying means to prevent the curtain wall from swinging.

Thereafter, the hanging unit is moved to the next mounting point of the structure, and the next curtain wall is sent out to perform the mounting operation. When all of the suspended curtain walls have been attached, the empty suspension unit is suspended and a plurality of curtain walls are newly mounted and lifted. In the case of a spandrel-type curtain wall, a curing shelf can be installed below the curtain wall hanging unit, so that the attachment members, tools, and the like can be prevented from falling.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing a state in which a spandrel-type curtain wall CW is being suspended at a mounting position by using a curtain wall unit box 1 as a suspension unit used in the curtain wall suspension method of the present invention. FIG.

In FIG. 1, a curtain wall unit box 1 includes a reciprocating suspension / delivery device 3 serving as a curtain wall suspension / delivery means for suspending a spandrel type curtain wall CW into a frame box 2 and delivering the same outside the box. A guide arm 14 as a means for preventing the suspended curtain wall from oscillating,
The unit box is provided with a self-propelled balance weight 5 as balance maintaining means movable in the front-rear direction of the unit box, and a horizontal curing shelf 6 for preventing the delivered member for attaching the curtain wall CW from falling.

The reciprocating suspension / delivery device 3 comprises:
It has two parallel straight beams 13, 13 attached to the upper part of the framework box 2, the tip of which protrudes forward of the framework box 2. Each beam 13,
13, a plurality of self-propelled hoists (hereinafter, referred to as
4 is mounted so as to be able to run freely.

The guide arm 14 of the anti-sway means is
A curtain wall CW suspended from each hoist 4 is disposed in the curtain wall hanging space of the frame box 2 so as to correspond to each hoist 4.
Can be rotated in conjunction with the operation of the hoist 4 between a holding position where the both sides of the hoist 4 are horizontally held and a release position where the holding is released by rising vertically.

The self-propelled balance weight 5 of the balance maintaining means travels in the front-rear direction on the linear beam 13 in response to the movement of the center of gravity accompanying the movement of the hoist 4, and maintains the balance of the entire framework box 2. And framing box 2
Is automatically controlled to keep the attitude of the player horizontal. The horizontal curing shelf 6 is provided on the front floor of the frame box 2 so as to protrude forward.

Reference numeral 7 denotes an operation switch for the hoist 4. The curtain wall CW is attached to the structure 20 by using the curtain wall unit box 1 in the following procedure. (1) Hanging the curtain wall into the unit: A plurality of curtain walls are hung in the curtain wall hanging space at the rear of the curtain wall unit box 1 placed on the ground by using the hoist 4 as a hanging / sending means. Hang CWs together.

The hoists 4 are attached to the right and left linear beams 13 and are paired. By hanging one curtain wall CW for each pair of the hoists 4, a plurality of curtain walls CW are formed. It is suspended in advance on the curtain wall unit box 1 on the ground. At that time, the guide arm 14 of the anti-sway means is rotated to the holding position for each suspended curtain wall CW, and the left and right sides of the curtain wall CW are pinched and anti-sway. (2) Lifting and temporary fixing of the curtain wall unit box: The curtain wall unit box 1 on which the curtain wall CW is suspended is suspended via a slinging wire 27 by a lifting device such as a tower crane to form a structure 20. Lift to the specified mounting position. The tip of the horizontal curing shelf 6 at the tip of the lifted curtain wall unit box 1 is inserted below (below the floor) a beam floor 22 stretched over a beam 21 of a structure 20. Also, the tip of the linear beam 13 is engaged with a hook 25 attached to a wire 24 stretched between the structural columns 23, and the curtain wall unit box 1 is protected from the wind by a gust or the like. Temporarily. (3) Removal of the curtain wall in the unit and attachment to the structure: The worker 28 stands on the beam floor 22 of the floor where the curtain wall CW is to be attached, and operates the hoist operation switch 7 of the curtain wall unit box 1. Then, the curtain wall CW in the front row is sent out to the mounting location.

At this time, first, the guide arm 14 for anti-sway pivots from the holding position to the release position, and the anti-sway of the curtain wall CW in the front row is released. Next, the first hoist 4 starts and the frontmost curtain wall CW
And begin to move forward. With the advance, the center of gravity of the curtain wall unit box 1 moves forward, and the weight balance is lost. Then, the self-propelled balance weight 5, which is a balance maintaining means, automatically travels in a direction (in this case, rearward) to sense and correct the imbalance and maintain the balance. However, when the imbalance does not occur, or when the imbalance does not become so large, the balance weight 5 is not always run.

Thus, the frontmost curtain wall CW
Is transported to the vicinity of the mounting position of the structure,
Operates the hoist operation switch 7 to position the curtain wall CW at a predetermined mounting height, and fixes the curtain wall CW to the beam 21 via the fastener 26. (4) Release of the temporary fixing and movement of the curtain wall unit box: Thereafter, the hook 25 of the wire 24 is disengaged from the curtain wall unit box 1 to release the temporary fixing, and the curtain wall unit is operated by operating the tower crane. The box 1 is slightly backed, slightly separated from the structure 20, and then moved laterally to the next location.
Thereafter, as described above, the temporary fixing of the curtain wall unit box 1 to the structure, the removal of the curtain wall in the unit and the attachment to the structure, the release of the temporary fixing, and the movement of the curtain wall unit box are sequentially repeated. Then, all the curtain walls CW suspended from the curtain wall unit box 1 are attached.

When all the suspended curtain walls CW have been mounted, the curtain wall unit box 1 is lowered to the ground by a tower crane, a new curtain wall CW is suspended, and the same operation is repeated. According to this embodiment, when the curtain wall CW is lifted, a plurality of the curtain walls are collectively hung in the curtain wall unit box 1, so that it is not necessary to perform the vertical operation of the tower crane for each curtain wall CW. Efficiency is improved and the time schedule (cycle process) of the tower crane can be significantly reduced as compared with the conventional case.
In addition, when a plurality of curtain walls CW are put together and hung in the curtain wall unit box 1, the overall weight increases, so that the influence of the wind is less than in the case where the curtain walls are lifted one by one (they are less likely to be blown by the wind), and to some extent. Construction is possible even in strong winds, and the progress of the process is facilitated.

In particular, in the case of a spandrel type curtain wall, the horizontal curing shelf 6 for preventing falling is installed in the curtain wall unit box 1 so that when the curtain wall CW is mounted on the structure 20, mounting bolts or the like are mistakenly installed. Can be received even if the mounting member is dropped, and various effects can be obtained, such as securing work safety.

In addition to the case where the curtain wall is sequentially attached to the structure 20 in the horizontal direction on the same floor as in the above-described embodiment, the vertical direction (up and down) of the structure 20 is changed from the upper floor to the lower floor. Direction). In that case, the procedure from (1) hanging the curtain wall into the unit, (2) lifting and temporarily fixing the curtain wall unit box, (3) taking out the curtain wall from the unit and attaching it to the structure is as follows. As above, but the procedure is different as follows.

That is, after the frontmost row of curtain walls suspended in the curtain wall unit box 1 is transported to, for example, a mounting location on the upper floor of the structure and mounted, the next hoist 4 is continuously run. Let me second
The curtain wall CW in the row is carried out to the outside of the floor of the curtain wall unit box 1 (in this case, the horizontal curing shelf 6 is not installed). Next, the hoist 4 is rewound by operating the hoist operation switch 7, and the curtain wall CW in the second row is hung to the mounting location on the floor immediately below and mounted on the structure.

Subsequently, the next hoist 4 is further driven to carry out the third row of curtain walls CW outside the floor of the curtain wall unit box 1, and the hoist 4 is rewound to further attach the lowermost floor. And attach it to the structure. After such operations are repeated to complete the work of attaching the curtain wall CW to a plurality of predetermined layers, the process proceeds to (4) the procedure of releasing the temporary fixing and moving the curtain wall unit box, and the curtain wall unit box 1 is moved. The curtain wall unit box 1 is lowered to the ground by a tower crane, and a new curtain wall C is moved.
W is suspended and the same operation is repeated.

Also in this embodiment, similarly to the above embodiment, since a plurality of curtain walls are lifted at one time, it is necessary to lift and lower the tower crane for each curtain wall as in the conventional case. And the construction cycle process and time schedule can be greatly reduced.
Since a unit in which a plurality of units are suspended has a heavy weight, the unit is less likely to be swept by the wind and is safer than a case where each unit is lifted. As a result, it is possible to obtain an effect that the efficiency of the curtain wall attaching operation is significantly improved as compared with the conventional art.

In each of the above embodiments, the operation of the hoist operation switch 7 and the operation of the guide arm 1 in the steps of taking out the curtain wall in the unit and attaching it to the structure.
The sequence operation of releasing the steady rest of the wheel 4, starting the hoist 4 at the head, and maintaining the balance by the automatic running of the self-propelled balance weight 5 has been described, but these can be easily performed by general sequence control.

FIGS. 3 to 5 show another embodiment of the suspension / delivery means. The hanging / sending means in the curtain wall unit box 1 of this embodiment is a circulation type hanging / sending device 3 as shown in FIG.
0. That is, the straight beam 1 in the case of the above embodiment is used.
3 instead of a long annular endless circulation rail 31
Are long and arranged in parallel in the front-rear direction, and are suspended from the horizontal beams of the framework box 2 and attached. A large chain wheel (chain gear) 32 for transporting a chain is rotatably attached to each end of each circulation rail 31. A link chain 33 is suspended between the front and rear chain wheels 32 to form a double closed chain. A circuit is formed, and the closed circuit composed of the two link chains 33 is simultaneously driven in the same direction by a drive device composed of one link chain feed motor 34 and a conduction chain 35. . Then, a plurality of chain hoists 36 are attached to a series of link chains, and a single curtain wall panel CW is hung for each pair of left and right chain hoists 36 and is conveyed to the front of the box (structure side). I have.

Further, the chain hoist 36 is wound up.
When the chain hoist 36 is located within the front end panel working range W of the front end of the link chain 33 in addition to the main power supply duct 37 that supplies power to the rewinding operation motor at an arbitrary position on the transport path. A sub power feeding duct 38 that supplies power only is provided (see FIG. 4). This sub power supply duct 38 incorporates an inverter 39I in its power supply circuit 39 to reduce the drive speed of the chain hoist hoisting / rewinding operation motor at the front end position,
Thereby, the vertical movement speed of the curtain wall CW is set to be very slow.

In this embodiment, as shown in FIG. 5, the curtain wall unit box 1 is lifted and temporarily fixed to a predetermined mounting position of the structure 20, and then the curtain wall of the suspended load is taken out. The work of attaching to the device is performed in the following procedure. 1) The operator operates the operation switch of the curtain wall unit box 1 to first drive the link chain feed motor 34 of the hanging / feeding device. As a result, the two link chains 33 synchronize and advance to the front of the unit box, and the chain hoists 36 connected to the link chains advance simultaneously. Therefore, each curtain wall CW suspended under the chain hoist 36 is simultaneously transported forward. When the frontmost curtain wall CW reaches the mounting position, the drive of the link chain feed motor 34 is stopped. At this time, the chain hoist 36 with the leading curtain wall suspended
Enters the front end panel working range W, and the connection of the power supply is switched from the main power supply duct 37 to the sub power supply duct 38.

2) Next, by operating the operation switch, the chain hoist 36 suspending the leading curtain wall
Is driven. The motor operates at a very low speed while being supplied with power from the sub power supply duct 38. Therefore, the hanging curtain wall can be safely attached to a predetermined position while being slowly moved up and down in response to the operation of the operation switch.

3) After the first curtain wall is attached, the chain hoist 36 is released by removing the sling. Then, the link chain feed motor 3
4 is again driven to feed the two link chains 33, and the curtain wall CW suspended from the next chain hoist 36 is advanced to the mounting position. At the same time, the empty top chain hoist 36 makes a U-turn along the circulation rail 33 and is sent back inside the rail.

In this way, the transport and installation of the curtain wall are sequentially repeated. When the suspension / delivery means is a reciprocating suspension / delivery device 3, since the feed of the self-propelled hoist 4 is guided by the linear beam 13, the used empty hoist is placed at the projecting portion at the tip of the linear beam 13. Therefore, it is necessary to extend the straight beam 13 by that much. On the other hand, in this embodiment of the circulation system, the empty hoist is sent rearward as the curtain wall mounting operation progresses, and does not need to be accumulated in the front, so that it does not interfere with the operation, and the overall length of the device is shortened. In addition, there is an advantage that the projecting portion of the beam does not interfere with the pillars of the structure or the like and is advantageous in terms of balance.

Also, by adjusting the lifting speed of the chain hoist 36 within the front end panel work range W to a very low speed, it becomes easy to align the curtain wall CW with the structure 20, and the operator can pinch his / her fingers. There is also an advantage that the danger of such as can be almost prevented. FIGS. 6 to 9 show another embodiment of the curtain wall steady rest means suspended from the curtain wall unit box 1. FIG.

The steadying means in this embodiment is a curtain wall pressing device 40. As shown in FIG. 6, a pad member 4 to be pressed against the lower surface of each curtain wall CW suspended in the curtain wall unit box 1
1 and a lifting / lowering device 42 for the pad member 41, and are installed on the floor of the curtain wall unit box 1.

The pad member 41 may be in the form of a flat plate made of a soft material such as rubber, plastics or the like, and is fixed to the upper surface of a lift plate 44 which is raised and lowered by a jack 43. The jack 43 may be of a hydraulic type, an electric type, or any other type.
In order to stabilize the curtain wall CW of the suspended load using the curtain wall pressing device 40, the jack 43 of the lifting device 42 is operated to raise the lifting plate 44, and the pad member 41 is pressed against the lower surface of the curtain wall. This pushing force is within a range not exceeding the weight of the curtain wall. As shown in FIG. 7, the pad member 41 bites into the space between the curtain walls and deforms, thereby preventing the curtain wall from swinging.

To release the steady rest, use the jack 43
Is operated in reverse to lower the elevating plate 44 so that the pad member 41
You only have to release the pressing. The pad member 41
Is to make the surface wavy as shown in FIG.
a may be cut into the space between the curtain walls CW. The lifting device 42 may be a combination of a link 45 and a small jack 46 as shown in FIG.

When the curtain wall pressing device 40 is used as the steady rest means, while the steady rest is once opened to mount the first curtain wall CW, the suspended load may be lost for some reason. Curtain wall CW
Even if the suspension position is displaced due to swinging, it is not necessary to correct the displacement one by one, and the pad member 41 can be reliably re-fixed at any position by simply raising the pad member 41. In addition, even if the curtain wall CW is made of an easily scratched material such as aluminum, there is an advantage that there is no possibility of damaging the finished surface of the surface.

FIGS. 10 and 11 show another embodiment of the anti-sway means. The steadying means is a connection fitting 47. That is, the curtain walls CW are connected to each other using a plurality of connection fittings 47. The connection metal fitting 47 is formed by bending a metal plate and raising both front and rear ends, and is formed substantially in a U-shape as a whole. The front end face thereof is provided on the back surface of the curtain wall CW suspended in the curtain wall unit box 1. Locking end face 4 to be screwed
7a. An engagement groove 47b is formed at the upper end of the locking end surface 47a by bending the U-shape. The rear end face is a connection end face 47c, and faces the locking end face 47a at an interval equal to or greater than the thickness of the curtain wall CW. The upper end thereof has an engagement protrusion slightly smaller than the width of the engagement groove 47b. 47d is formed by bending into a hook shape.

In order to stabilize the curtain wall CW of the suspended load using the connection metal fittings 47 of the steadying means, the locking end faces 47a of the connection metal fittings 47 are attached to the back surface of each curtain wall CW by screws. At the same time, the engaging groove 47b on the locking end face and the engaging projection 47d on the connecting end face 47c of the other connecting fitting 47 attached to the adjacent curtain wall CW are engaged and connected. In this way, the lower ends of the curtain walls CW are connected to each other as shown in FIG.

When the steady rest is released, the preceding curtain wall CW is sent out (moved forward) toward the structure.
Before operating the hoist, the preceding curtain wall C
W is lowered slightly as indicated by arrow Y in FIG. As a result, the engaging projection 47d of the connecting end face 47c of the preceding connecting fitting 47 is disengaged from the engaging groove 47b of the locking end face 47a of the adjacent connecting fitting 47, and the steady curtain of the leading curtain wall CW is prevented. The connection is released. After that, the leading curtain wall CW is sent out toward the mounting position of the structure, and the screw is removed by a worker's hand to remove the connection fitting 4.
7 may be removed. The same operation is repeated for each subsequent curtain wall CW.

In the case of the steady rest using the connecting fitting 47, the device itself is very simple and lightweight, and no special mechanical device is required for attachment and detachment. The space underneath can be reduced, and the installation uses the back surface of the curtain wall, so there is no danger of damaging the finished surface of the curtain wall surface. Further, since the steady rest is sequentially opened from the preceding curtain wall, there is no need to open the steady rest of the remaining trailing curtain wall CW one by one, so that there is an advantage that work safety is maintained.

FIGS. 12 to 14 show a curtain wall unit box 1 in which a curtain wall CW is suspended.
Another embodiment of the balance maintaining means is shown. The balance maintaining means of this embodiment is provided with either one of two front wires or two rear wires among four sling wires 27 (only two wires are shown) for hanging the curtain wall unit box 1 on the crane hook CF of the tower crane. Is a hanging wire length variable device 50 that adjusts the wire length of the pair.

Specifically, as shown in FIG. 12, an electric chain block 50 serving as a variable wire length device is attached to each of the two front slinging wires 27, for example.
Is interposed. The two built-in electric chain blocks 50 are operated by a pendant switch 52 attached to the structure side of the curtain wall unit box 1 while an operator visually checks the inclination of the curtain wall unit box 1. .

Alternatively, a tilt angle sensor 53 for detecting the degree of tilt of the curtain wall unit box 1 is mounted, and a controller 5 is provided based on a signal from the tilt angle sensor 53.
By operating the electric chain block 50 via 4 and adjusting the length of the chain 51, the hanging length of each of the two slinging wires 27 may be automatically changed.

The balance of the curtain wall unit box 1 is maintained by the variable wire length device 50 as follows. As shown in FIG. 13, when the front curtain wall CW in the curtain wall unit box 1 is reduced by hanging, the center of gravity G of the curtain wall unit box 1 is shifted backward from the box center line CL. In that case, the curtain wall unit box 1 starts to incline in the direction in which the rear part falls and the front part rises. At this time, the chain 51 of the electric chain block 50 is extended, and the two front slinging wires 2 are moved forward.
7 and the hanging center (crane hook C
The curtain wall unit box 1 is kept horizontal by moving the (F position) backward so as to match the center of gravity line G of the curtain wall unit box 1.

On the other hand, as shown in FIG. 14, when all the curtain walls CW in the curtain wall unit box 1 move at the same time at the time of lifting, the center of gravity line G of the curtain wall unit box 1 moves forward from the box center line CL. Then, the curtain wall unit box 1 starts to tilt in the direction in which the rear part rises and the front part descends. At this time, the chain 51 of the electric chain block 50 is rewound, and the two front slinging wires 27 are moved forward.
To reduce the hanging length (the crane hook C
By moving F) forward to match the center of gravity line G of the curtain wall unit box 1, the curtain wall unit box 1 is kept horizontal.

The hanging wire length varying device 50 has a simpler mechanism than the self-propelled balance weight 5 in the above-described embodiment, and can reduce the overall weight. As a result, the curtain wall unit box 1 Thus, the number of curtain walls mounted can be increased, and the construction ability is further improved. FIG. 15 shows another embodiment of the curtain wall unit box 1.

The curtain wall unit box 100 of this embodiment is a split box in which the lower frame 101 is detached from the upper frame 102 so as to be detachable. This split curtain wall unit box 10
An example of the curtain wall hanging method using the method 0 will be described. (A) Hanging step: The curtain wall unit box 100 in an empty state is hung on the ground.

(B) Lower frame separating step: For example, the lower frame 1 having a horizontal curing shelf 6 for preventing the mounting member from falling.
01 is separated from the upper frame 102. (C) Stock mount mounting step: On the ground, a predetermined number of curtain walls CW are arranged in advance vertically at equal intervals on the stock mount 103 via the fall prevention piece 104. The upper frame 1 in the stock frame 103
02 is suspended.

(D) Curtain wall slinging step: Each curtain wall CW in the stock frame 103 is attached to the upper frame 1
02 are hoisted together on each of the chain hoists 36 of the hanging / feeding device 35 mounted on the device. (E) Stock frame release process: Curtain wall C
The upper frame 102 on which W is slung is lifted to some extent by a crane, and the stock frame 103 is separated.

(F) Lower frame hanging step: The lifted upper frame 102 is hung on the ground, and the previously separated lower frame 101 with the horizontal curing shelf 6 is connected to the upper frame 102. (G) Lifting step: The curtain wall unit box 100 in a suspended state is lifted to a predetermined mounting position on the structure.

Thereafter, the curtain wall CW of the suspended load is sequentially mounted at a predetermined mounting position according to the procedure described above, and when the curtain wall unit box 100 becomes empty, the above steps are repeated again. With the use of the split-type curtain wall unit box 100, a predetermined number of curtain walls CW set in advance on the stock stand 103 on the ground can be slung on the chain hoist 45 while the curtain wall is being attached to the structure. Non-split curtain wall unit box 1
In this case, the operation time can be saved as compared with the case of (1).

The present invention can be applied not only to the spandrel type curtain wall but also to other types of curtain wall. In this case, the curtain wall unit box 1 is provided with a horizontal curing shelf 6 for preventing falling. do not do.
