Description

Truss Decker Exclusive Forklift Truck

The present invention loads the truss decker used when constructing the floor of each floor during the construction of a high-rise building such as a building, and then moves the caterpillar forklift to an installation position after loading it on a driving loading section formed on the top surface of the caterpillar. It relates to a truss deck forklift truck dedicated to the truss deck that is fixed by welding after lifting the truss decker one by one from the location loaded by the forklift installed in the crawler and moving it to the installation location.

In general, the floors of high-rise buildings such as buildings are near the base and are constructed using a truss decker equipped with a large number of wires on the top surface of the plate, and the truss decker is installed one by one and then welded outside the truss decker. Or, by fixing it with nails to form a truss decker floor, apply a mortar of cement to the top surface of the truss decker floor, and then fire it to construct the floor of the building.

As described above, the conventional method for fixing the truss decker on the bow is fixed by welding or fixing nails after the operator transports the truss decker made of a certain standard to the installation position by hand.

However, the conventional method as described above has a problem in that it takes a lot of time and inconvenient to work because the worker manually transports and installs the truss decks one by one, and then fixes them with welding or fixing nails.

In particular, there is a problem that the worker is to be carried one by one, and it is difficult to carry the heavy truss decker, so the work has to be carried out slowly.

Therefore, in order to solve the above problems, it was previously filed by the applicant of the present invention and "10-0911827" "A panel fixing device for architecture" was pre-registered.

The pre-registered "panel fixing device for construction" is guided by a guide tube by a first cylinder, the width of which is adjusted, and the lower member having a square frame shape with indentation grooves on both sides;

A guide roller for stacking the upper portion of the lower member and guiding the indentation groove is provided at both ends and is guided in a guide tube by a second cylinder to adjust the width of the lower member by a third cylinder fixed to the lower member. A rectangular frame-shaped intermediate member coupled to the lower member to be movable from the top;

A fixed tubular tube having a flange portion in which fixing pieces provided inside the upper surface of the intermediate member are placed is fixed, and a truss decker is mounted on the upper surface and has a driving loading portion loaded with a plurality of truss deckers. It is characterized in that it consists of a conventional first and second moving means to move to the installation location and a conventional automatic welding means fixed to one end of the second moving means.

However, due to the limited size of the floor member and the horizontal member, there is a problem in that the load is only half of the quantity, the movement is intermittent and the speed is slow, resulting in poor workability.

Moreover, there is no forklift, so it cannot load itself, and it cannot move horizontally (left and right), so movement is very limited.

The moving means and the flipping means installed on the upper surface of the upper member are too cumbersome, so there is a problem that is not suitable for realizing an automated process.
