Description

[Detailed explanation of the idea] The present invention relates to a mounting structure for a gondola hanging device.

In structures such as buildings, even after construction, the rooftop is used, for example, to hang gondolas for repairing external walls or cleaning windows, or to tie down curtains and tents. As shown in Figures 1 and 2, a plate material 03 with nine rings 01 attached to one end and an angle-shaped bent part 02 formed on the other end is used to form a formwork such as a plywood board when pouring concrete. Board 04
A through hole 05 is provided in the hole 05, and the bent part 02 is inserted into the hole 05 from the side of the bent part 02, and the bent part 02 is attached to a predetermined one of the reinforcing bars 06 for the rooftop peripheral wall by welding or binding with wires 07. The round ring 01 was positioned to protrude further inward.

However, it is difficult to obtain a highly strong round ring 01, so it is difficult to use it as a gondola hanging device.When suspending a gondola, for example, it is difficult to obtain a ring 01 with a suitable strength installed on the roof of a cooling tower. The reality is that the members are only used for attaching hanging curtains and tying up tents. In addition, when removing the formwork plate 04 after the concrete hardens, the round ring 01 is the through hole 0.
5, the formwork plate 04 corresponding to the installation location of the plate material 03 has to be broken, and the formwork plate 04 becomes scrapped.Even if a plywood board is used, the plate material 03 Rooftop wall 08
If they were to be provided at predetermined intervals along the road, the number of sheets would increase to a considerable extent, which would be extremely uneconomical.

The present invention enables a high-strength gondola hanger capable of suspending a gondola to be installed economically without damaging formwork plates.

In order to achieve the above-mentioned object, the mounting structure of the gondola hanging device of the present invention forms angle-shaped first and second bent portions at both ends of the bar, and the first bent portion has the following features:
The second bent portion is tied to reinforcing bars for the roof peripheral wall and integrated with poured concrete so as to be exposed in a downwardly protruding position.

In other words, since it is only a matter of bending and forming a bar,
It is possible to use high-strength materials such as steel rods, eliminate the need for welded parts like conventional round rings, and also allow the formwork plate to have a through hole with a diameter slightly larger than the diameter of the bar. By simply providing a hole, the formwork plate can be removed by aligning it along the bar and tilting it along the bending direction at the second bending part.

Therefore, it has become possible to use it effectively not only for attaching hanging curtains and tying up tents, but also for hanging gondolas, without using any other strength members.

Furthermore, after concrete is poured, the formwork plate can be removed without any damage, and the formwork plate can be used repeatedly, making it extremely economical.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings.

An angular first bent portion 2 and a second bent portion 3 are formed at each end of a galvanized steel rod 1 to constitute a gondola hanger 4.

To attach the gondola hanging tool 4, the second bent part 3, which is longer than the first bent part 2, is attached to predetermined vertical bars 5 and horizontal bars 6 as reinforcing bars for the roof peripheral wall. 7 and mounted by the first
The tip side of the bent portion 3 is maintained in a posture facing downward. Then, a formwork 10 composed of a plywood board 8 as a formwork board and a crosspiece 9 is fixedly installed at a predetermined position, and the gondola hanging tool 4
A through hole 11 is formed at a predetermined location in the plywood board 8a corresponding to the plywood board 8a, and as shown in FIG. The plywood board 8a is fixed with the portion 2 protruding outward, concrete is poured in this state, and the gondola hanger 4 is attached while being integrated by the poured concrete.

In disassembling the formwork 10 described above, the plywood board 8a corresponding to the gondola hanging tool 4 is rotated in a state opposite to the case of attaching the formwork 10 described above, as shown in FIG. It is removed from the first bending section 2 through.

The through hole 11 is formed into an elongated hole, and is configured so that the formwork 10 can be easily attached and detached.

The gondola hanging tools 4 are provided on the rooftop peripheral wall 12 at a predetermined interval (for example, about 3 m), and when hanging the gondola, as shown in FIGS. 5 and 6, the first bent portions 2, 2, a single pipe 14 connecting the ends of the wires 13, 13 is attached, and the wires 15, 15 are connected to each other.
is tied to the gondola hanging devices 4, 4 by, and
By interlocking the backing plate 16 and the crosspiece 17, the single pipe 14 is more reliably prevented from coming off and falling from the first bent portions 2, 2. The wires 13, 13
Although not shown, each other end side is connected to a work gondola via a pulley or the like attached and fixed to the rooftop peripheral wall 12.

When hanging the gondola described above, the abutting plate 16
It is not necessary to provide the crosspiece 17.

The gondola hanger 4 may be constructed by bending a high-strength rigid tube instead of the steel rod 1 described above, and these are collectively referred to as the rod 1.

The second bending portion 3 may be bent in the same direction as the first bending portion 2. Further, the first bent portion 2 only needs to project downward in its entirety, and may be formed in a circular ring shape.
