Description

Tower crane work support device {Apparatus for supporting a tower crane}

The present invention relates to a tower crane work support device, which allows a worker to securely and conveniently work when fixing a tower crane to a building to firmly support a tower crane installed when building a high-rise building. A work support device.

In general, tower cranes are used to easily move materials to a desired place when high-rise buildings or buildings are built. These tower cranes must be firmly fixed by lifting and moving materials with high loads.The tower crane not only secures the base of the tower crane with an anchor on the ground, but also secures the side of the tower crane to the building to make the tower more stable. The crane should be supported.

In order to support the tower crane, conventionally, the side of the tower crane is fixed to the building by using a 'dedicated frame' as shown in FIG. 1, one side of the dedicated frame is fixed to the building B and the other side of the tower crane. The method of welding and fixing to (T) has been widely used. These dedicated frames were welded along the height direction of the tower crane to support the tower crane at a plurality of points.

However, this conventional fixing method may cause a safety problem as the worker has to fasten the fixed hook to the tower crane, and there is a problem that the working time is long because the worker's behavior is inconvenient and difficult to work effectively. .

In addition, there is a problem that the welding does not proceed easily as the operation of the operator is inconvenient as described above, because the welding to fix the dedicated frame to the tower crane.

In addition, due to welding, a dedicated frame should be initially adapted to the angle of the building and the tower crane. However, if the welding is not good, it is difficult to correct it, and it is difficult to separate the welded parts when dismantling the tower crane after the completion of the building. have.

In addition, there is a problem that can not reuse the dedicated frame after welding dismantling.

In addition, there is a problem that labor costs increase because a skilled worker is required for welding a dedicated frame.

The present invention has been made to solve the above problems, an object of the present invention is to provide a tower crane work support device that can secure a more stable position when the operator fixed the tower crane to the building.

The present invention is derived to solve the above problems, the vertical support is fixed in parallel to the frame of the tower crane erected in parallel with the building; A horizontal support fixed to the main support at a right angle; A hinge unit fixedly installed at the horizontal support unit and having a hinge coupled to a dedicated frame for fixing the tower crane to the building; An inner support bar having one end fixed to the horizontal support portion; A support frame fixed to the other side of the inner support bar; And a plate fixedly installed to extend outwardly from the support frame.

As a result, the operator can work on the plate to secure a stable position to effectively and safely install the dedicated frame on the tower crane even in high altitude, the angle of the dedicated frame by the hinge freely according to the distance or angle between the tower crane and the building It can be adjusted to easily install a dedicated frame.

Here, the horizontal support portion, the connecting portion is formed to be connected to a plurality so as to be installed corresponding to the size of the tower crane, the connecting portion is preferably hinged by the hinge bar.

Thus, since the height of the tower crane is also determined according to the height of the building, the size of the tower crane is also variable, so that the work support device can be easily installed universally even if the size of the tower crane is changed by the structure of the horizontal support. .

In addition, the support frame is installed so as to be perpendicular to the inner support bar, a coupling portion protruding upward is formed in a portion corresponding to the inner support bar, the inner support bar is formed with an insertion portion into which the coupling portion is inserted, After the coupling portion is inserted into the insertion portion, it is preferable that the coupling portion and the inner support bar is screwed in a horizontal direction with the support frame.

In this way, the load applied to the work support device is primarily supported by the horizontal support part and the inner support bar, and by supporting the load by the inner support bar and the support frame secondarily, a stable structure can be designed while supporting a larger load.

In addition, it is preferable that the outer support bar is installed on the free end side of the plate upwards.

Thereby, the safety accident by the carelessness or mistake of an operator can be prevented.

According to the present invention described above, the operator can work on the plate to secure a stable position can be installed in a dedicated frame to the tower crane effectively and safely even at high altitude, the hinge portion freely according to the distance or angle between the tower crane and the building By adjusting the angle of the dedicated frame can be easily fixed to the dedicated frame installation.

In addition, since the height of the tower crane is also determined according to the height of the building, the size of the tower crane is also variable, so that even if the size of the tower crane is varied by the structure of the horizontal support, the work support device can be easily installed accordingly. .

In addition, the load applied to the work support device is primarily supported by the horizontal support part and the inner support bar, and by supporting the load by the inner support bar and the support frame secondarily, a stable structure can be designed while supporting a larger load.

In addition, it is possible to prevent safety accidents due to operator carelessness or mistake.

Hereinafter, with reference to the accompanying drawings will be described a tower crane work support apparatus according to a preferred embodiment of the present invention.

2 is a view for explaining a state in which the tower crane work support device is installed according to a preferred embodiment of the present invention, Figure 3 is a view for explaining the tower crane work support device shown in Figure 2, Figure 4 is It is a figure for demonstrating a principal part.

2 to 4, the tower crane work support apparatus 100 according to the preferred embodiment of the present invention includes a vertical support 110, a horizontal support 120, a hinge 130, and a support frame 150. And plate 160.

The vertical support 110 is installed in the frame constituting the tower crane as shown in Figure 3, it is preferable to have a shape corresponding to the outer shape of the outer frame of the tower crane so that a more stable structure can be designed. . In Figure 3, the longitudinal cross-sectional shape in the longitudinal direction is 'L-shaped' to ensure the maximum area of contact with the frame of the tower crane, but the shape of the outer frame of the tower crane can be applied accordingly if different It is natural.

The horizontal support part 120 is fixedly installed at right angles to the vertical support part 110 between the vertical support parts 110, and hinge parts 130 are installed at both ends thereof.
