When performing pile construction from the ground, this reverse driving method establishes a permanent pillar or temporary pillar of the underground structure at the tip of the pile, performs primary excavation, then constructs a first floor beam and a top slab. Then, the top slab is used as a work space, mountain retaining, and a cut beam. After that, excavation and construction of the vehicle body are sequentially repeated to complete the underground structure.

[0003]

However, when the above-mentioned reverse striking method is adopted, the opening for loading and unloading the material is restricted by constructing the top slab, and the ground driving work and the underground driving work are restricted. The following problems have arisen in the transportation of underground construction materials due to various restrictions caused by simultaneous construction. (B) Since the upper and lower floors are constructed at the same time, there is a ground drive, which limits the types and lifting heads of unloading heavy equipment. (B) It is necessary to have a loading place in the underground to temporarily store the cargo, and it is necessary to change it according to the progress of the construction. (C) Since the basement unloading area is located immediately below the opening of the top slab, if the material remains concentrated in that area or is being worked on, the subsequent transportation stops. (D) Since the opening position of the top slab is limited,
More horizontal movement in the underground.

The present invention has been made in view of the above-mentioned problems, and has as its object to efficiently and safely transfer materials during construction work to the types of unloading heavy equipment, heads, and the like. An object of the present invention is to provide a material transfer device for construction work that can be performed without any restrictions.

[0005]

In order to achieve the above-mentioned object, a material transporting apparatus in construction work according to the present invention is provided with an upper rail installed horizontally at a lower portion of a floor on an upper floor, and traversed by the upper rail. The device is supported so as to be able to traverse, and an opening for unloading is provided vertically through each floor, and a lower rail is provided horizontally at the lower part of each floor across the opening for unloading and with respect to the upper rail. Installed vertically so that when it is located in the unloading opening, a lifting rail connecting the lower rails on both sides of the opening is suspended and supported by the traverse hoisting apparatus via a suspension chain so as to be able to move up and down, and the unloading is performed. A lift guide member for a lift rail is provided at the opposite end of the lower rail facing the opening for opening, and a travel trolley is supported by the lift rail and the lower rail so as to run. That.

[0006]

When the material is transported from the material loading floor to the lower floor, the traverse hoisting device supported by the upper rail is moved above the material loading truck, and the traveling trolley supported by the traversing hoisting device and the lifting rail. A little, adjust the position of the hanging hook so that it is directly above the suspended load, sling, and rotate the suspended load according to the direction of the unloading opening opening on the upper floor, Next, move the traverse hoisting device to a position immediately above the unloading opening,
Next, the elevating rail is lowered and connected to the lower rail on the predetermined floor, and then the traveling trolley is moved from the substantially central part of the elevating rail to the lower rail via the end part, and is conveyed to the unloading place on the predetermined floor.

[0007] The above-described material transfer apparatus is also applicable to horizontal transfer of construction materials in a basement floor, or to removal of remaining materials and excavated soil from the basement floor to the ground. In addition, if the positional relationship between the approach direction of the material loading truck, the position of the unloading opening, and the transport route to the lower floor is limited due to the plane restrictions of the construction site, select the installation position of the traverse hoisting device. By changing the pattern and the distance relationship by the control device and using the same, it can be applied to many works.
