Description

{Expendable Deck Plate Apparatus For Car Gondola}

The present invention relates to a gondola, and more specifically, to a gondola expansion platform that can expand the area of the floor plate on which a worker can step.

A gondola (car gondola) is a device widely used to lift or lower loads on the roof of a high-rise building. It is usually installed temporarily during the construction of a building and used to transport construction materials. Gondolas are also used as stepping stones for workers for exterior work on buildings (e.g., exterior wall panels, painting, window installation, etc.).

A gondola is an arm-bending type in which the arm in charge of the wire rope that hangs the work platform undulates and is a device that can carry a work surface suspended from the rooftop of a building to the other side, and an arm-fixed type in which the arm is fixed. And, an electric trolley that runs on a rail installed on an I-beam protruding above a building's awning or structure is attached, and the work surface is suspended from the trolley by a wire rope, so the gondola can run and go up and down along the rail. There is a monorail type.

In addition, a gondola is a lifting device that raises or lowers the work surface, an over-winding prevention device that prevents over-winding of the wire rope, an interlock device that prevents simultaneous operation when two or more operating parts are installed in a location, and a work surface It consists of a safety device that prevents acceleration and descent.

Conventional technology includes Korean Utility Model Registration Application No. 20-2006-0022306, which is a new concept that allows workers to work simultaneously from above and below by implementing a gondola that can cover the height of about one floor of a building. By introducing , overall work efficiency can be increased, including reduction of work time, reduction of construction costs, and ease of work. Above all, construction work on assembly-type wall units that cover the entire area can be performed more efficiently. We propose a gondola for high-altitude work in high-rise buildings.

And Republic of Korea Patent Application No. 10-2017-0169949 is a jig installed while supported on the upper railing of the structure, a deck for working on the outer wall while moving up and down along the outer wall of the structure while hanging on the jig, and the deck and jig. It relates to a gondola composed of a wire that lifts the deck by winding and unwinding through a winder installed on the deck. Specifically, the jig is a pair of upper and lower rails fixed to the left and right along the railing. ; a pair of moving assemblers moving while engaged with the upper and lower rails; A post erected vertically through the pair of moving assemblers; An angle-adjustable base formed to rotate back and forth while being axially installed on the upper part of the post; A length-variable arm formed to adjust its length forward and backward through multi-step coupling while coupled to the angle-adjustable base; and a cylinder for controlling the rotation angle of the length-variable arm in a state of being axially coupled between the post and the arm, respectively, thereby providing a functional mobile gondola that not only improves safety but also improves convenience of use. will be provided.

In this way, the conventional work platform or loading board on which the worker stands has a limited planar area. In other words, the side facing the building is rectangular with the long side. Conventional work platforms for gondolas provide a narrow passageway, which limits the worker's range of movement and inevitably limits his or her work activities. These work platforms for gondolas lead to a decrease in work efficiency.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached to the specification. An embodiment of the present invention will be described with simultaneous reference to FIGS. 1 to 5.

The gondola expansion scaffold (1) according to the present invention includes a plate (10), side wall plates (20, 21, 30, 31), and connection brackets (40, 50).

The plate body 10 is a long rectangle, and the upper surface 11 has an uneven surface to prevent slipping. The plate body 10 is made of a metal material, and the ratio between the long side and the short side can be 5 to 20:1. Even as a single plate, it provides an area for workers to work on. In other words, only one gondola expansion scaffold (1) can be used.

The side wall plates (20, 21, 30, and 31) are fixedly installed along the three edges of the plate body (10) so as to form a right angle to the plate body (10). The side wall plates 20, 21, 30, and 31 are provided to prevent the plate body 10 from bending, but also function as a guide or limiting means to prevent the object placed on them from slipping away.

According to an embodiment of the present invention, the side wall plate is composed of upper side wall plates (20, 21) and lower side wall plates (30, 31) of the same height. According to another feature of the present invention, the side wall plates 20 and 30 installed on the long sides of the side wall plates are made of an L-shaped section steel or a D-shaped section steel. As shown, the upper side wall plate 20 is provided by an L-shaped section steel, and the lower side wall plate 30 is provided by a D-shaped section steel. The plate body is sandwiched between the upper side wall plates 20 and 21 and the lower side wall plates 30 and 31 and fixed by welding.

According to another feature of the present invention, the plate body 10 may further include a cover plate 12 integrally protruding on a side of the long side where the side wall plates 20, 21, 30, and 31 are not installed. As shown in FIG. 4, the cover plate 12 is used to prevent gaps between the plates 10 by stacking them up and down when two gondola extension scaffolds 1 and 2 are placed facing each other.

According to another feature of the present invention, a reinforcing bar 32 to prevent sagging of the plate 10 is provided on the side of the long side of the plate 10 where the side wall plates 20, 21, 30, and 31 are not installed. It can be fixedly installed on the bottom of the plate body 10 by welding. The reinforcement bar 32 is made of L-shaped section steel.

Connection brackets 40 and 50 are fixedly installed on the outer surfaces of the side wall plates 20, 21, 30 and 31 by welding or bolting along the extension direction. A plurality of connection brackets 40 and 50 are used for connection to external members. The connection brackets (40, 50) include a sleeve-type bracket (40) into which a pipe body can be inserted in the vertical direction, and a ring-type bracket (50) with a horizontal hanging hole (51) into which a ring or wire can be inserted. can do. The sleeve-type bracket 40 can be installed on the side wall plates 20 and 30 installed on the long side, and can be composed of three pieces. The ring bracket 50 can be installed on the side wall plates 21 and 31 installed on the short sides, and one can be installed in the middle.

According to the above configuration, it is used in the form shown in FIG. 4.

That is, the present invention is applied to three sides of a conventional gondola (100) having the basic structure of a gondola.

By connecting the expandable footrest (1), the left and right width and length can be expanded. If the cover plate (12) is placed on the upper surface of the edge of the existing gondola and fixed with bolts, etc., and safety railings are installed on each side using sleeve-type brackets (40), the area of the existing gondola can be expanded. This makes it possible to transport bulky items and increase work speed.

As shown in Figure 4, the side on which the scaffold 1 is not installed is the side in contact with the building. In addition, instead of installing the footrest (1) on all three sides, it may be possible to install and use it only on some of them.

For reference, Figure 5 is a photograph of a gondola with the footrest (1) of the present invention applied to one side. As shown, the footrest (1) of the present invention is applied to the outer surface of the gondola.

What has been described above are only a few examples based on the technical idea of the present invention. Those skilled in the art will be able to make various modifications using the examples without exceeding the scope of the technical idea of the present invention expressed in the claims. For example, all of the embodiments described above can be freely combined and practiced by those skilled in the art, and any combination should be construed as falling within the scope of the present invention.
