Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel suspension device used for attaching a curtain wall panel or the like to an outer wall of a building or the like.

[0002]

2. Description of the Related Art In recent years, in building structures and the like, a curtain wall construction method in which ready-made panels are sequentially attached in order to construct an outer wall structure is becoming mainstream. Panels are usually constructed by installing hoisting equipment such as crawler cranes, truck cranes, and tower cranes at the construction site, and hoisting the panels alone or after erection of multiple panels as an erection unit to attach them to the specified outer wall position. Is going.

Incidentally, when the panel is hoisted by the hoisting equipment, conventionally, as shown in FIG. 7, hanging wires 52 are attached to hanging fittings 51, 51 attached to the upper end of the panel 50, and the hanging wire 52 is attached. It is hooked on the hanging hook 53 of the crane and lifted.

[0004]

However, in the case of the above-mentioned suspension supporting state, when the panel 50 is swung by the wind, the panel 50 easily rotates around the axis of the suspension wire 54, so that the suspension is performed. There is a problem that the work of inserting becomes very unstable and it becomes difficult to position it on the outer wall surface for mounting.

Further, as shown in FIG. 8, particularly when it is desired to hang the new panel 56 by dropping it inside the existing panels 55, 55, the interference between the hanging hook 53 of the crane and the building is eliminated. For this purpose, hanging length L = 30m
The sling wire 52 of a certain degree or more is required, but in this case, the slung panel 52 becomes unstable because the sling wire 52 is long, and the position controllability deteriorates with the above-described problem of panel rotation. There are problems such as making it difficult to drop into narrow spaces.

Therefore, the main object of the present invention is that the panel can be suspended and supported in a stable state so as not to rotate, and the operability of position control in this suspended state is excellent.
An object of the present invention is to provide a panel suspending device that allows a suspending operation to be performed easily even in a narrow portion of an outer wall portion.

[0007]

In order to solve the above-mentioned problems, the present invention is a panel suspension device for suspending the panel, which is interposed between a hoisting equipment and a panel, and which is for suspending the panel. The hanging device is provided with a hanging point for the lifting equipment in the middle, and a hanging point for the panel is provided on one side with this hanging point as a boundary, and a balance weight is provided on the other side, and the panel is suspended in a balance state. It is characterized by having it.

Therefore, in the case of the present invention, since the separation is secured between the hoisting point for the hoisting equipment and the hoisting point for the panel, it is not necessary to use a long-dimension sling wire, and Since the hanging hook can be operated in a state where it is separated from the body and panel surface, it is extremely easy to operate. Further, since the posture of the panel is stable when the panel is in a suspended state, the suspended panel can be easily and accurately positioned on the outer wall surface or the narrow portion of the outer wall portion, so that the lifting operation is efficiently performed. be able to. Further, in the case of the suspension device, the length of the sling wire can be shortened, and the inertia moment I (second moment of area) of itself is very large, so that it is difficult to rotate even if it is fanned by some wind. When the length of the sling wire is short, the slant angle of the sling wire stretched in an inverted V shape becomes small, so the tension introduced inevitably becomes larger than the balance of the forces in the vertical direction, and the tension difference rotates. Since the resistance force against is increased, the rotation of the panel is suppressed. Further, in the physically rotational movement of the rigid body, if the moment of force is constant, the larger the moment of inertia I is, the smaller the angular acceleration, that is, the change in the angular velocity. That is, when the inertia moment I is large, the change of the rotational movement becomes slow, and the inertia moment I is an index indicating the difficulty in changing the rotation state. Therefore, the rotation of the panel is suppressed by interposing the suspension device having a large inertia moment I as described above. In addition,
The rotation suppression of the panel itself will be described later.

On the other hand, the structure of the panel suspension device may be a simple frame structure or a beam structure, but if the stability of the suspension device itself is taken into consideration, a three-dimensional frame structure is obtained. Is desirable.

Further, by making the center of gravity of the panel suspension device eccentric to the balance weight side from the suspension point for the lifting equipment, more effective rotation control can be achieved and the weight of the balance weight can be reduced. desirable.
As for the moment of inertia I of the suspension device, if the same thing, the moment of inertia for the eccentric position is larger than the moment of inertia for the position of its center of gravity, so it is more effective to shift the center of gravity from the suspension point (rotation axis). The rotation can be suppressed. It should be noted that this is the same principle that a top with an eccentric center of gravity does not rotate well.

On the other hand, in order to suppress the rotation of the suspended panel itself, in the panel suspension device, two suspension points for the panel are provided and mounting wires are respectively provided at these suspension points, Make sure that the panel is suspended by two-point suspension. Therefore, depending on the length of the pedestal wire, the panel itself receives the rotational force due to the wind, but does not rotate first.

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, a panel suspension device 1 (hereinafter, simply referred to as a suspension device) according to an example of the present invention has a three-dimensional frame structure in which a steel material such as an H-shaped steel or a channel steel is assembled as a structural material. Is configured as. Specifically, on one side surface side, the lower member 10A and the diagonal members 11A, 12
The unequal scaled triangular framework is made by A and
The vertical member 13A extending from the apex position to the lower member 10A is vertically provided to form the truss assembly surface member A on one side. Similarly, on the other side surface side, the lower member 10B and the diagonal members 11B and 12B form an isosceles triangular shape. And the vertical member 13B extending from the apex position to the lower member 10B is hung vertically to form the truss assembly surface material B on the other side. The two truss assembly surface materials A and B are the connecting materials 14 to 16. The three-dimensional frame structure is configured by being connected by.

In the present invention, the crane suspension pieces 3, 3 are fixed by welding or the like to the apex portions of the truss assembly surface members A, B, that is, the intermediate position of the suspension device 1, and the crane suspension hooks are fixed to the crane suspension hooks. The ends of the hanging wire 17 are connected via a shackle or the like. Further, hanging pieces 4, 4 for hanging a panel are fixed to one end sides of the lower members 10A and 10B, that is, one end sides of the crane hanging piece 2 as a boundary. On the other hand, balance weights 2, 2, ... Are arranged on the opposite side of the suspension pieces 4, 4 installation site, that is, on the other end side (connection material 14 site) with the crane suspension piece 2 as a boundary. As the balance weight 2, any suitable one can be used, but in the present embodiment, the cross sectional dimension is 110 mm × 110 mm and the length is 1.
A 500 mm billet is passed between the diagonal members 11A and 11B and then fixed by welding or the like so as not to fall.

Further, as shown in FIG. 2, the diagonal member 11A on one side is made longer than the diagonal member 12A on the other side so that the truss assembly surface members A and B have an outer shape of an isosceles triangle.
The center of gravity O of the suspension device 1 is eccentric to the balance weight side by a distance S from the position of the suspension piece 3. As a result, as described above, the moment of inertia I of the suspension device 1 with respect to the axis of rotation can be increased, more effective rotation suppression can be expected, and the weight of the balance weight 2 can be reduced. As shown in FIG. 3, the weight of the balance weight 2 is determined so that the lower members 10A and 10B are horizontal when the panel P is suspended.

First, as shown in FIG. 4, the mounting wires 18, 18 are locked to the upper end of the panel P placed on the unit container 20, and the crane hook 21 is raised. And hang up the panel P. As shown in FIG. 5, when the panel P is completely raised,
The suspension device 1 becomes horizontal. The panel P is lifted up to the outer wall mounting position as it is, and as shown in FIG.
After the panel P is positioned at a predetermined mounting position, the panel P is fixed with a mounting bolt or the like to release the locking of the mounting wire 18. At this time, the suspension device 1 rotates simultaneously with release of the tension of the pedestal wire 18, but if the pedestal wire 18 is removed while the suspension hook 21 is slightly retracted to the outside, it is suspended from the building. There is no risk of interference with the device 1. In addition, at this time, the suspension device 1 swings to reduce the impact when the tension is released. A chain block may be provided in the middle of the mounting wire 18 to finely adjust the hanging position.
