Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suspended load taking stage for an opening.

[0002]

[Prior Art]

 In construction work in urban areas, etc., a lifting opening is often formed on the floor inside the building. Then, when using a lifting machine such as a crane to hang it down through the lifting opening or to load the lifted load to the floor side, it is very difficult to pull the load directly from the floor. Because of the danger, this is commonly done using an open suspended load capture stage that can be moved horizontally over and above the lifting opening. That is, the suspended load is once placed on the suspended load capturing stage that has been moved above the lifting opening, and then the suspended load is moved to the floor side together with (or from) the stage. There is.

However, since a handrail is provided around the lifting opening to prevent a fall accident, prior to moving the suspended load capturing stage onto the lifting opening, a handrail is installed. It is necessary to carry out the troublesome work of reattaching the handrail after removing the part and taking in the suspended load, and moreover, every time the handrail is attached / removed, there is a risk of falling. There was also a safety issue.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned current situation, the present invention provides a suspended load taking-in stage for an opening in which a handrail is attached around the lifting opening so that the suspended load can be safely and easily taken in. Is.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, the end of the stage body on the side of the lifting opening which is configured to be horizontally movable between the upper position and the lateral position of the lifting opening formed on the floor inside the building. The first handrail along one side of the lifting opening is provided on each side, and the second handrails along both sides of the lifting opening are arranged parallel to the moving direction of the stage body from both ends of the first handrail. The second handrail and the handrails provided on both sides of the lifting opening are extendedly fitted to each other so as to be slidable in the longitudinal direction to form a suspended load take-in stage for the opening.

[0006]

[Action]

 According to the above configuration, by horizontally moving the stage main body, the fitting depth between the second handrail mounted on the stage main body and the handrails provided on both sides of the lifting opening is changed. The actual length of the handrail will change. In addition, when the stage body is moved over the lifting opening, the handrail length is substantially shortened, and there is no handrail on both sides of the lifting opening closed by the stage body. Therefore, the handrail does not get in the way, and it is possible to take in a long suspended load.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a suspended load taking stage for an opening according to the present invention. In the figure, reference numeral 1 is a rectangular lifting opening formed on a floor 2 inside the building. A handrail 3 and handrails 4, 4 assembled by a single pipe and a right-angled clamp are provided on one side of the lifting opening 1 on the short side and on both sides of the adjacent long side. There is.

Reference numeral 5 denotes a stage main body that is horizontally movable between an upper position and a lateral position of the lifting opening 1, and has wheels 6 at four corners on the lower surface. Reference numerals 7 and 7 denote two guide rails having grooves 7a that rotatably support the wheels 6, are placed on the floor 2 inside the building in parallel with each other, and are perpendicular to the guide rails 7 and 7. Are connected to each other by connecting rods 8 made of two angle members. Inside the groove of each guide rail 7, stoppers 9a and 9b are provided at both ends in the longitudinal direction, which come into contact with the wheels 6 and define the moving range of the stage body 5.

As shown in FIG. 4, a locking portion 10 having a downward opening is formed at each end of each connecting rod 8 by welding an angle member or the like. Then, by engaging the locking portion 10 with the side plate portion 7b of the guide rail 7, the distance between the guide rails 7, 7 is maintained constant, and the engagement is released, whereby the guide rail 7, 7 and the connecting rods 8, 8.

A first handrail 11 is provided at an end of the stage main body 5 on the side of the lifting opening 1 along the short side of the lifting opening 1. The illustrated first handrail 11 has a plurality of vertical sheath pipes 12 welded to the frame 5a of the stage body 5, and the lower end side of the single pipe support 13 is inserted into and supported by the sheath pipes 12. A single pipe 15 is horizontally installed in two stages on the 13 through an orthogonal clamp 14.

Further, the second handrails 16 and 16 extending from both ends of the first handrail 11 along both sides of the lifting opening 1 are parallel to the moving direction of the stage main body 5 (parallel to the guide rails 7 and 7). ), And the second handrails 16 and 16 and the handrails 4 and 4 provided on both sides of the lifting opening 1 are fitted to each other so as to be slidable in the longitudinal direction. .. Specifically, each second handrail 16 is configured by using a single pipe that is thinner than the single pipe for the handrail 4, and the free end side of this thin single pipe is placed inside the single pipe for the handrail 4. It is slidably inserted. Reference numeral 4a is a sheath pipe that supports the support column 4b of the handrail 4, and is welded to the upper surface of the upper flange of the beam steel frame 17.

According to the above configuration, as shown by the solid line in FIG. 1, when the stage body 5 is moved to the side of the lifting opening 1, the four sides around the lifting opening 1 are touched by hand. The handrail 3, the first handrail 11, the second handrail 16, 16 and the handrails 4, 4 are located to prevent a fall accident.

As shown in FIG. 5, when a hoisting machine such as a crane hoists through the hoisting opening 1 or takes in the hoisted load W to the floor 2 side, it is shown by a phantom line in FIG. As described above, the stage body 5 is moved onto the lifting opening 1. As a result, the second handrails 16 and 16 slide with respect to the handrails 4 and 4, and the length of the handrail is substantially reduced, so that there is no need to remove the handrail. Then, the suspended load W is placed on the stage body 5 and moved to the floor side together with the stage body 5. Therefore, the suspended load W can be taken in safely with the handrail always.

Further, although handrails are always present on the four sides around the lifting opening 1, when the stage body 5 is moved onto the lifting opening 1, the handrail is not attached to the stage body 5 of the lifting opening 1. Therefore, since the handrails do not exist on both sides of the closed portion, even if the load W is long, the load W is rotated by approximately 90 degrees when the load W is passed through the lifting opening 1. By doing so, it can be placed on the stage main body 5 and taken into the floor without interfering with the handrail.

Although the guide rails 7 and 7 are installed on the concrete pouring floor in the above embodiment, the guide rails 7 and 7 are installed on the deck plate floor as shown in FIG. It is also possible.

[0016]
