Description

[Detailed description of the invention] This invention relates to a gondola hanging device used during building exterior wall construction, and in particular, a gondola hanging device that allows a working gondola and a curing gondola to be hung at the same time from a common joist. This relates to a lowering device.

In general, gondolas are mainly used to carry workers up and down the walls of buildings to carry out wall construction work, and to prevent workers from falling during work, gondolas are used to carry workers up and down the walls of buildings. It is mainly used to hold the lower end of the work gondola 1, which is a fence, and the protective net 2, which hangs down from the roof along the outer wall surface to prevent falling objects from scattering to the ground during construction of the outer wall of the building. A fence is placed around the three edges of the board other than the front surface that contacts the wall side to prevent falls so that workers can walk safely on the board, and a distance is maintained between the front side of the wall side and the wall surface. There is a gondola 3 provided with a tread, and conventionally these gondolas were suspended via cables 6, 7 between different joists 4, 5 provided on the roof.

By the way, although the work gondola 1 and the protection gondola 3 have some structural differences in terms of their functions, their main parts are almost the same, so they have many parts in common, so the installation of the cables is The location is also the same.

Therefore, the projecting beam 5 of the working gondola protruding from the roof and the projecting beam 4 of the curing gondola are set at the same pitch with a predetermined distance from each other. 1 and the curing gondola 3 are suspended.

The curing gondolas 3 are usually arranged horizontally in a row so that their sides touch each other, and the working gondolas are suspended by cables I so that the workers on the gondolas are not unable to work. It goes up and down between it and the protective net 2.

However, after installing the joists 4 for the curing gondola on the rooftop at a predetermined pitch, when installing the joists 5 for the work gondola, if there is an obstacle such as a handrail in the installation position of the joist 5, move it from there. Therefore, when the working gondola 1 is suspended between the shifted projecting beams, the working gondola 1 related to the shifted projecting beam 5 and the working gondola 1 adjacent to this working gondola 1 are suspended between the shifted projecting beams 5. A disadvantage is that an area P where work is impossible occurs in the vertical direction of the building wall corresponding to the width of the shift between the gondola 1 and the gondola 1, and an additional work gondola must be placed to work on this area P. It had

This invention improves the drawbacks of the conventional ones as described above, and will be explained below based on the embodiment shown in the drawings. A roller 10, which is a first guide member, is provided on the top surface of the tip of this projecting beam.

The curing gondola 3, which can be raised and lowered by itself, has a receiving member 12 on the inner side of its lower part, the end of which touches the peripheral wall surface 11 of the building and catches falling objects.
and a winder 1 equipped on the gondola 3.
The cable 6 fed out from the 3 is supported by the roller 10 and the roller 15 which is the first guide member at the upper end of the main pillar 14 erected near the rear end of the truss, and is tied at a desired position on the rear roof. A plurality of curing gondolas 3 suspended by cables 6 in this manner are arranged horizontally in a line along the peripheral wall of the building, and are connected to horizontal shafts installed between the ends of each joist 9. The lower edge of the protective net 19, to which the upper edge is attached, is received by each of the horizontally arranged curing gondolas 3.

Further, a support piece 16 serving as a second guide member is provided on one side of the central portion of each projecting beam 9, and the cable 7 fed out from a winder 17 installed in the work gondola 1 is attached to the support piece 16 and the support piece 16, which is a second guide member. After being supported by the support piece 18, which is a second guide member provided on one side of the main pillar 14, it is tied to a desired position on the roof in the same manner as described above.

Therefore, the curing gondolas 3 suspended via the winder 13 by the cables 6 supported by the rollers 10 and 15 located on the upper surface of the tip of the projecting beam 9 and the upper surface of the main column 14 are arranged horizontally in a row, and The work gondola 1 suspended via the winder 13 by the cable 7 supported by both support pieces 16 and 18 is connected to the protective net 19 stretched via each protection gondola 3 and the building as shown in the fourth figure. Go up and down between the wall and the wall.

This invention is based on the first guide member supporting the cable of the curing gondola and the second guide member supporting the cable of the working gondola as described above.
Since the guide members are installed on a common projecting beam, the curing gondola and the work gondola can be aligned in the same manner by providing only one type of projecting beam at a certain interval, making it impossible to work on the surrounding wall of the building. It has the advantage that it does not create a large area, and that the installation work of the joist installed on the roof can be shortened because the joist is used both as a curing gondola and a working gondola.
