Description

  The present invention relates to a construction elevator, and more particularly to a construction elevator that also serves as a cargo handling platform.

  Conventionally, in construction sites such as small and medium-sized office buildings and condominiums, a construction elevator has been installed for lifting relatively small and light interior materials, and a cargo handling platform has been installed for lifting large, heavy exterior materials. Is increasing. For example, as shown in FIG. 11, an elevator 2 for long span construction is provided on the outer peripheral side of a building 1 to be constructed, and a load handling table 3 is provided on the outer peripheral side of an intermediate floor. The interior material is lifted from the first floor through the construction elevator 2, while the exterior material is lifted onto the load handling platform 3 by a stationary or mobile crane 4. Since medium and small-scale construction sites have a limited amount of material to be lifted, the operation rate of the construction elevator is low, and the operation rate of the cargo handling platform is also low. In small and medium-sized construction sites, it is necessary to introduce a number of machines with such low operating rates, and the actual situation is that temporary construction costs on the site are under pressure.

  Further, when a normal loading / unloading stand is replaced with a floor on another floor, the replacement work must be performed by an on-site crane, construction work, or the like, resulting in a replacement work. Moreover, since the dredging requires work at a high place and at the edge of the floor during the refilling work, it is necessary to consider work safety.

  In addition, elevators for long span construction, which are frequently used in medium and small construction sites, generally have a lowering speed than the elevator structure standard (for example, an elevating speed of about 8.3 m / min). However, material raising / lowering is quick (for example, the raising / lowering speed of about 26-41.6 m / min). Therefore, as the lifting floor (lifting height) increases, the difference in the lifting time is generated, and the lifting / loading time by the crane requires less lifting time. In addition, the crane operation rate is not high at small and medium-sized construction sites, and the lifting work time on the loading platform can be secured without problems.

  For this reason, it has been desired to use the construction elevator as a cargo handling stand. As a conventional technique that realizes this, for example, a construction elevator described in Patent Document 1 is known. This elevator for construction is arranged close to the building to be constructed, a rail part extending in the vertical direction, a floor part for placing materials, a lifting device for raising and lowering the floor part along the rail part, The floor portion is provided so as to be detachable, and includes a floor expansion portion that extends the floor width of the floor portion to the outside of the building to expand the material placement area. Thereby, the mounting space of material can be expanded and it can utilize as a gantry also to a large sized material. Further, in this construction elevator, a box-shaped boarding seat portion is disposed so as to be foldable at an end portion of the floor surface. It is possible to reduce the boarding seat part and widen the material placement area by rotating the movable side wall forming the passenger seat part to the fixed side wall side and rotating the movable canopy side to the fixed canopy side. .

  However, the construction elevator of Patent Document 1 has the following problems, and there is room for improvement. First, it is difficult to add a floor expansion part to the floor of the elevator at the construction site in consideration of workability. In addition, the folding method of the movable canopy of the passenger seat part is a hinge type, and when a worker with a short height returns the folded passenger seat part to the original box shape (at the time of restoration), the movable canopy does not reach the hand, Recovery work may be difficult. In addition, a dedicated instrument (for example, a rod-shaped metal fitting) for rotating and moving the movable canopy when the movable canopy is folded and restored is separately required.
