DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading stage device used for loading a load on each floor of a building frame or the like.

[0002]

2. Description of the Related Art A loading stage is provided when unloading to each floor using a crane or the like after the construction of a building skeleton. This loading stage can be installed on all floors or can be set up for the number of floors. If not, or if the opening for loading on the building side is in a straight line in the vertical direction and installing stages on all floors will interfere with unloading work, disassemble and rearrange the stages for each floor. I have.

[0003]

However, it is troublesome and uneconomical to provide a loading stage on all floors or to disassemble and rearrange the stages for each floor as in the prior art. Even more so.

[0004] The present invention has been made in order to solve such a disadvantage, and an object of the present invention is to provide a loading stage device capable of performing a loading operation easily and economically.

[0005]

According to a first aspect of the present invention, there is provided a loading stage device for loading a load into each floor of a building frame or the like. A stage portion to be moved, a supporting portion for movably supporting the stage portion in a vertical direction, and a restraining means for restraining the movement of the stage portion on a predetermined floor.

According to a second aspect of the present invention, in the loading stage device, the restraining means includes a retractable portion provided on the stage portion so as to be able to protrude and retract, and the retractable portion provided corresponding to each floor and protruding from the stage portion. And a receiving member for receiving the portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an explanatory front view of a loading stage device as an example of an embodiment of the present invention, FIG. 2 is an explanatory plan view seen from the direction of arrow II in FIG.
FIG. 3 is a partial perspective view of the unloading stage device, and FIG.
FIG. 5 is a sectional view taken along line IV-IV of FIG.
FIG. 6 is an explanatory diagram for explaining a method of restricting the movement of the stage unit at a predetermined floor, and FIG. 7 is an explanatory diagram showing a state in which the movement of the stage unit is restricted.

This unloading stage device 1 is shown in FIGS.
As shown in the figure, the stage 2 on which the load is suspended, the gantry 4 arranged on both sides in the longitudinal direction of the stage 2, and the gantry 4 supporting the stage 2 movably in the vertical direction. A guide rail 5 (supporting portion) and restraining means 6 for restraining the movement of the stage portion 2 at a predetermined floor are provided.

The stage section 2 is formed in a box shape that is long in the left-right direction in FIG. 1, and guide rollers 7 are provided on both sides in the longitudinal direction. The guide roller unit 7 includes a vertically long rectangular mounting frame 8, and two rollers 9 are mounted on the mounting frame 8 so as to be separated from each other in the vertical direction. The roller 9 is arranged with its rotation axis oriented in the short direction of the stage section 2.

Further, two rollers 10 are mounted on the mounting frame 8 between the two rollers 9 so as to be vertically separated from each other. The roller 10 is arranged with its rotation axis oriented in the longitudinal direction of the stage 2.
The roller diameter is larger than the thickness of the roller 9 in the axial direction.

The gantry 4 is composed of a framework scaffold (bitty scaffold) and the like, and is installed on both sides of the stage 2 in the longitudinal direction. A guide rail 5 extending along the vertical direction is provided at a portion of the gantry 4 facing the guide roller unit 7.
(See FIG. 4).
reference). The guide rail 5 has a guide groove 5a,
As shown in FIGS. 4 and 5, the rollers 9 and 10 of the guide roller unit 7 are inserted into the guide grooves 5a.

When the stage 2 is vertically moved while being suspended by the crane 12 or the like in the inserted state, the roller 9 rolls on the bottom of the guide groove 5a and the roller 10 rolls on the side wall of the guide groove 5a. Then, the stage section 2
Is supported by the guide rail 5 via a roller 9 so as to be movable in the vertical direction, and the stage 2 is also supported by the guide rail 5 in the horizontal direction via the roller 10 during the movement. The occurrence of backlash or the like during the vertical movement of the stage 2 is preferably prevented, and the smooth movement of the stage section 2 is ensured.

The restraining means 6 includes a slide bar (projecting portion) 13 whose front end can be protruded and retracted in the longitudinal direction of the stage 2 from the four bottom corners of the stage 2, and a stage provided to correspond to each floor. And a receiving member 14 for receiving the tip of the slide bar 13 protruding from the four bottom corners of the portion 2. A handle 13a for facilitating the slide bar 13 to be inserted and removed from the four bottom corners of the stage 2 is attached to the tip of the slide bar 13.

The receiving member 14 is formed of a long member extending along the short direction of the stage section 2 and is fixed to the frame 4a of the gantry 4 via a clamp 15 (see FIG. 6). Between the receiving member 14 and the building frame 4 a located above the receiving member 14, a string-like body 16 such as a wire for receiving the load of the stage 2 is wound. In FIG. 1, reference numeral 17 denotes an unloading port for taking in a load into the building frame.

Next, a method of using the loading stage device 1 will be described. After the stage 2 is lifted up by about several cm (about 5 cm) using the crane 12, the slide bars 13 protruding from the four bottom corners of the stage 2 are pushed in, and then the stage 2 is suspended by the crane 12. The stage unit 2 is moved up and down to be positioned on a predetermined floor.

Next, as shown in FIG.
Then, the slide bar 13 is pulled out from the four bottom corners and protrudes. In this state, the stage 2 is slowly lowered by the crane 12 and placed on the receiving member 14 (see FIG. 7). Thereby, the movement of the stage 2 is restricted, and the transfer of the stage 2 to the predetermined floor is completed. After the relocation is completed, a load such as materials is suspended on the stage 2 by a crane, and the suspended load is taken into the building frame from the unloading port 17.

As described above, in this embodiment, the stage 2 is moved up and down to shift to a required floor, and the movement of the stage 2 is restricted by the restricting means 6 at the shift position. As in the past, there is no need to set up the loading stages on all floors.Moreover, when there is not enough space to install the loading stages for the number of floors, or when the opening for loading on the building side is vertically aligned. In this case, it is not necessary to disassemble and rearrange the stages for each floor, so that the loading operation can be performed easily and economically.

Further, it is possible to restrain the movement of the stage 2 only by pulling out the slide bar 13 from the four bottom corners of the stage 2 and projecting the same, and lowering the stage 2 with the crane 12 and placing the stage 2 on the receiving member 14. So you can
The restraint can be easily performed.

[0019]

As is apparent from the above description, according to the first aspect of the present invention, the stage is moved up and down to shift to a required floor, and the movement of the stage is restrained by the restraining means at the shift position. As in the past, it is not necessary to provide a loading stage on all floors as in the past, and it is no longer necessary to disassemble and rearrange the stages for each floor, making it easy and economical This can be effectively used particularly when there is not enough space for installing the loading stages for the number of floors, or when the opening for loading on the building side is vertically aligned.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the movement of the stage is restricted only by projecting the projecting portion from the stage and lowering the stage in this state and placing the stage on the receiving member. Therefore, there is an effect that the restraint can be easily performed.
