Highly accurate construction is difficult, and there was a problem in terms of ensuring safety.

[0004]

SUMMARY OF THE INVENTION The present invention has been made with the above points in mind. The object of the present invention is to use a panel made of aluminum or the like to accurately measure the outer wall of a tower building in a short period of time. An object of the present invention is to provide a construction method that can be installed safely and well, and a suspension device suitable for the construction method.

[0005]

The technical means taken by the present invention to achieve the above object are as follows. That is, in the method for converting a large panel unit for a tower outdoor wall according to the first aspect of the invention into a large unit by assembling a panel for a tower outdoor wall on the lower ground surface, a tower roof is constructed on the roof, and then the panel large unit is mounted on the roof. It is characterized by constructing an outdoor wall of the tower by hoisting it up and mounting it on the tower. In the first invention, the lower ground surface means not only the ground but also the rooftop slab of the low-rise part. That is, in the case of a building in which a high-rise part with a tower is built on the low-rise part, the large panel unit may be manufactured on the rooftop slab of the low-rise part.

The suspending device according to the second aspect of the present invention comprises a plurality of upper jigs each having a fixed pulley attached to the tip thereof and detachably attached to the upper end of the structure, and a first traverser having a horizontally long linear shape.

It is composed of a large panel unit A mounted around the tower 1.

As shown in FIG. 2, the large panel unit A is constructed by attaching a necessary number of aluminum panels 4b for outdoor tower walls having an appropriate width L to the front surface of a steel base 4a framed in a grid pattern. It has a horizontal width and a vertical width corresponding to one side surface of the tower 1. Reference numeral 5 denotes a traverser used for lifting the large panel unit A, which is detachably connected to the base 4a.

In constructing the tower outdoor wall 3, prior to the construction of the tower building 1 or in parallel with the construction work of the tower building 1, as shown in FIG. A large panel unit A is produced, and the large panel unit A is hoisted by a lifting device such as a winch or a tower crane 6 to be hung on the roof 2 and the base 4a is fixed to the tower 1 by appropriate fixing means (bolts, nuts, welding, etc.). And cover the four sides of the tower 1 with the large panel unit A,
As shown in FIG. 1B, the tower outdoor wall 3 is constructed.

In the above embodiment, the large panel unit A is formed in a flat shape having a size corresponding to one side of the tower 1, but when the area of the tower 1 is small, a three-dimensional shape (for example, a tower outdoor wall) is formed. May be formed in a U-shape or an L-shape in a plan view, or may be formed in a tubular shape surrounding four peripheral surfaces of the tower 1, as shown in FIG.

4 to 7 show another embodiment of the first invention. In this embodiment, the first invention is applied to an all-weather construction method for a steel-framed multi-storey building, and prior to the construction of the tower building 1, a large panel unit A made of a lower ground surface (rooftop slab in the lower part) S It is characterized in that the large panel unit A is used as a windbreak countermeasure for steel frame construction welding work even while sliding up to the construction floor.

More specifically, 7 in the drawing is a steel frame of a pillar or a beam which is a skeleton of a multi-story steel building. The steel frame 7 can be erected in multiple floors (for example, 3
It is performed in order from the bottom with 1 layer as a section.

B is a waterproof floor provided on the uppermost floor every time a steel frame is built, and the waterproof floor B constitutes each node roof surface and shields the interior from rainfall. Although various concrete configurations can be adopted as the still water floor B, in the illustrated embodiment, as shown in FIG. 6, the deck plate 29, which is the main installation material (floor formwork) for the floor, is made of beam steel. The waterproof floor B is constructed by laying in a watertight manner on the top. A removable lid (not shown) is provided at the openings such as the temporary opening a for loading and unloading materials and the staircase b formed on the water blocking floor B, and the opening is closed by the lid when it rains. I am doing it. Tower crane 6
Is provided at a position penetrating the water stop floor A, for example,
The mast of the tower crane 6 penetrating through the tower crane opening c is provided with a skirt-shaped eave (rain shelter) larger than the tower crane opening c to prevent rainwater from entering during rainfall. .

The large panel unit A is hoisted by a winch or a tower crane 6 and slid up to the construction floor. It is attached to the side surface of the steel frame 7 until the tower building 1 is constructed, It forms the wall surface and shields the inside from rain and wind. As shown in FIG. 5, this large panel unit A has a base 4
The sheet base 8a made of steel is connected to the upper part of a, and the appeal sheet 8b used for advertisement or the like is pasted on the front surface of the steel base 8a and the appeal sheet 8b. It is removed when building, and is not an essential component for the large panel unit A. 30 is a narrow ventilation net provided at the four corners of each node wall. The ventilation net 30 serves to maintain the working environment in good condition by performing ventilation inside and performing welding work, but impairs the function of shielding side rain and wind from the entire wall surface of each node. It is formed as narrow as possible so that it does not exist.

C is an aluminum curtain wall fitted with a window glass. The curtain wall C is made into a large unit in advance by an assembling work on the lower ground surface (rooftop slab of the low-rise portion) S, and is lifted by a winch or a tower crane 6 as the steel frame construction progresses, and from the lower node. Will be built in sequence. D is the curtain wall C after sliding up the large panel unit A
It is a safety net that is attached to the side of the steel frame until it is built.

The process of the all-weather construction method for a steel multi-story building will be described below. As shown in (a) of Fig. 7, the steel frame erection of Section 1 is performed,
Water-tight floor B by laying the deck plate on the top floor watertight
Make up. The water-stop floor B constitutes each node roof surface of the first node, and the inside is shielded against rainfall. After that, the large panel unit A is attached to the side surface of the steel frame 7. As a result, each node wall surface of the first node is configured, and the inside is shielded from side rain and wind. In this state, the internal welding work (indicated by the two-dot diagonal line) is performed. As shown in (b) of FIG. 7, the steel frame erection of Section 2 is performed.
Similar to the case of Section 1, the top floor deck plate is laid in a watertight manner to form a water-stop floor B, and the water-stop floor B forms each node roof surface of the second section. After that, the large panel unit A is slid up and attached to the side surface of the steel frame of Section 2 to form each section wall surface of Section 2. As shown in FIG. 7C, the on-site welding work is performed on the inside of the section 2 (portion indicated by a two-dot diagonal line). Next, the curtain wall C, which is made into a large unit, is built on the side surface of the steel frame of Section 1 to construct a weatherproof wall surface after the steel frame construction. The above steps (1) to (5) are repeated, and finally, as shown in (d) of FIG.

According to the above-mentioned embodiment, not only is it shielded from rainfall from above, but it is also shielded from side rain and wind, so that a site that occupies a large construction period weight in steel frame construction. Welding work can be performed regardless of the weather. Moreover, since the large unit A of the panel for the outdoor wall of the tower, which will be a blindfold for the rooftop equipment, is manufactured in advance and used as each node wall surface, the main construction material is effectively used and it is economical, The tower outdoor wall 3 can be constructed safely in a short period of time.

In this embodiment, the following measures are taken in order to shorten the refilling time when the large panel unit A is slid up and ensure safety. That is, FIG.
As shown in FIG. 9, a large number of steel arms 10 are rotatably pivoted around a longitudinal axis P on the base 4a and the seat base 8a of the large panel unit A, and these steel arms 10 are attached to the girder steel frame. 9a
Also, the large panel unit A is temporarily received (mounted on the side surface of the steel frame 7) by being mounted on the cross beam steel frame 9b and fixed with the bolts 11. And when sliding up the large panel unit A, the steel arms
The bolt connection between 10 and the girder steel frame 9a and the girder steel frame 9b is released, and as shown in FIG. 10, the steel arm 10 is rotated around the longitudinal axis P to the outside of the girder steel frame 9b, and in this state, The large unit A of the panel is slid up together with the steel arms 10.

Therefore, the member for temporarily receiving the large panel unit A slides up at the same time as the large panel unit A, compared to the case where a large number of temporary receiving members are individually transported to the upper steel skeleton and attached. As a result, the refilling time is greatly reduced, the construction period is shortened, and the risk of falling is eliminated. Reference numeral 12 shown in FIG. 8 is a surface of the large panel unit A at the time of sliding up by guiding the locking pieces 13 and 14 projecting on the back side of the base 4a or the sheet base 8a so as to be slidable in the vertical direction. This is a guide rail that prevents the steady rest.

FIG. 8, FIG. 11 and FIG. 12 show a suspension device E that can be suitably used in the above construction method. In this suspension device E, a fixed pulley 15 is attached to the tip end thereof, and four upper jigs detachably configured to the upper end of the structure (in this embodiment, a rectangular tubular steel frame column). Tool 16 and a horizontally long linear first traverser 18 made of H-shaped steel that is configured to be connectable to a large panel unit A via a shackle 17 or the like.
And a wire rope 21 wound around the fixed pulley 15 and a moving pulley 19 mounted on the first traverser 18, and the length of which can be adjusted by a chain block 20.
A horizontal traverse second traverser 22 made of H-shaped steel and connected to the first traverser 18 via a
A short suspender 23 such as a sling wire for suspending and supporting the suspension 16 is provided. Reference numeral 23a is a hook attached to the tip of the hanging device 23.

The upper jig 16 is provided with a horizontal arm portion 16a made of H-shaped steel material and a pair of steel leg portions 16b continuously provided below the horizontal arm portion 16a. Then, attach the legs 16b to the structure (steel column, etc.) with bolts and nuts.
It is configured to be fixed at 25. A perforated plate 26 for suspending and supporting the hoisting device such as the tower crane 6 is provided on the upper surface of the arm 16a, and a perforated plate 27 for connecting one end of the wire rope is provided on the lower surface. Is provided.

The upper jig 16 has a second
As a fixing means for fixing the traverser 22 in a mounted state, a bolt hole is formed at a predetermined position on the upper surface of the arm 16a, and the lower flange of the second traverser 22 mounted on the arm 16a is attached to the bolt / nut 28. It is configured to be fixed by tightening with.

By using this suspension device E, the large panel unit A can be slid up quickly and easily and safely on each side of the building. That is, since the large panel unit A is slid up along the guide rail 12 provided on the side surface of the steel frame, if there is an inclination with respect to the horizontal direction, the large panel unit A will be placed between the guide rail 12 and the locking pieces 13 and 14. Twisting occurs and smooth sliding is hindered, but if the above hanging device E is used, by adjusting the length of each wire rope 21 with the chain block 20, the levelness of the first traverser 18 is corrected. Therefore, twisting does not occur between the guide rail 12 and the locking pieces 13 and 14, and smooth slide-up is possible.

Moreover, when the slide-up on one side surface of the building is completed and the suspension device E is replaced on the other side surface of the building, as shown in FIG. 11, the first traverser 18 is used.
Is suspended near the upper jig 16, and is suspended and supported by the upper jig 16 by the lifting tool 23, and the second traverser 22 is placed on the arm portion 16a of the upper jig 16 and the bolts and nuts are attached. By fixing with 28, the entire device can be stored in a compact state. In this state, the bolt connection with the erection piece 24 is released, and as shown in FIG.
It can be moved to the other side of the building by a lifting device such as a tower crane 6 and used for sliding up the large panel unit A on that side.

Therefore, it is not necessary to divide or assemble the first and second traversers 18, 22, the fixed pulley 15, the movable pulley 19, the hangings 23, etc. every time the refilling is performed, and the refilling can be done in a short time. The work can be done efficiently, and since the work of refilling at high places is reduced, it is possible to work with plenty of room and improve safety.
