DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for lifting materials and equipment in building construction.

[0002]

2. Description of the Related Art Heretofore, there has been known a technique of lifting by a loading gantry using a mobile crane such as a large crane for construction or a truck crane on a fixed loading gantry.

[0003]

However, since the load receiving gantry is of a fixed type and is to be lifted by a crane or the like to receive the load, the load receiving gantry provided on each floor is arranged so as not to overlap in plan. It is necessary to. For this reason, the positions of the load receiving gantry in the vertical direction are scattered for each floor, and a crane worker requires a skilled person.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an equipment lifting device that can be easily lifted by a small and simple crane and that uses a slide type loading gantry in which the loading gantry is provided on the same span on each floor. I have.

[0005]

According to the present invention, there is provided an equipment lifting apparatus using a slide-type loading gantry for lifting equipment for construction work, wherein a boom is provided on the top floor of the building frame. A crane for lifting materials is provided, and a loading gantry is provided on each floor of the building skeleton, the loading gantry is provided with a loading platform having sliding means that can be slid by a holder beam provided in the floor, and the loading gantry is mounted inside the building. The crane and the loading gantry are installed at the same vertical position.

[0006]

[Explanation of the operation and effect] Since the present invention is configured as described above, the materials and equipment are lifted by the crane provided on the roof of the skeleton or on the top floor, and the loading platform of the loading receiving gantry on the floor requiring loading is slid. What is necessary is just to overhang the outside of the skeleton by means, and to lower the equipment on the carrier. Then, the loaded carrier may be pulled into the body by the slide means and delivered to a required location. In the case of unloading, the unloading can be easily performed in the reverse procedure.

[0007] Therefore, a small and simple crane can be used to lift a cargo receiving gantry provided on the same span.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, members having the same functions are denoted by the same reference numerals, and description thereof will not be repeated. In FIGS. 1 and 2, a small crane 4 having wheels 4 a is installed on the top floor (n) of the building frame 1, and a material 7 is hung on a boom 5 via a wire 6. Each floor of the building frame 1 is provided with a cargo receiving gantry indicated by reference numeral 10 in its entirety. In the illustrated example, the cargo receiving gantry 10 of the floor (n-4) that receives the material 7 is provided with a cargo platform 12.
Are slid from the holder beam 15 by a channel-type rail and rollers 15a, which are sliding means, and are extended out of the frame 1 by a manual winch 11.

The cargo receiving gantry 10 has a side handrail 14 and a front handrail 13 around the carrier 12, and the handrail is
For example, as shown on the floor (n-2), when the loading platform 12 slides from the holder beam 15 to the inside of the skeleton 1, the handrail is left on the holder beam 15.

Reference numeral 3 denotes a support between floor beams during construction of the building frame, reference numeral 2 denotes a floor beam, and L denotes the ground. Reference numeral 7a indicates a material being lifted.

Therefore, the loading gantry 1 provided on each floor
Even if 0 is in the same span, if a required loading receiving platform is extended by a manual winch when required, the lifting of the equipment can be easily performed by a crane having only a lifting function.

Further, it can be used for unloading waste such as temporary equipment and residual materials.

[0014]

The present invention has the following advantages because it is configured as described above.

(1) Since a floor crane fixed at a fixed position having no turning and traveling functions or a small crane installed on the roof is used, the crane does not need to be moved.

(2) Since a large crane for building the frame is not used, no process control is required, and necessary materials and equipment can be lifted at any time.

(3) Since the cargo receiving gantry can be set up in the same span, only one place for the equipment and materials to be carried in at the construction site is required.

(4) The construction period can be shortened and the cost can be reduced.
