Abstract
A removable construction device for use in a building under construction is disclosed. The device is partially positioned inside the building and locked to the building and is partially cantilevered outside of the building. The device has a movable platform section that may be positioned inside or outside of the building on the device. Construction materials may thereby be moved into the building or may be removed from the building by use of the device associated with an outside lifting crane.
Claims18
A removable construction device for use on a building under construction, the device being positioned partly inside the building and partly cantilevered outside of the building and having a movable platform section that may be positioned inside or outside of the building on the device, comprising:
- (a) a frame;
- (b) a movable platform section positioned on and carried by the frame, the platform section being designed to be movable on the frame from a position outside of the building to a position inside the building for moving a load into or out of the building;
- (c) means, associated with the frame and the platform section, for moving the platform section;
- and
- (d) means associated with a portion of the frame and the building, for locking the frame to the building prior to moving a load into or out of the building.
A removable construction device for use on a building under construction, the device being positioned partly inside the building and partly cantelevered outside the building and having a movable platform section that may be positioned inside or outside of the building on the device, comprising:
- (a) a frame;
- (b) a movable platform section slidably mounted on the frame;
- (c) a hydraulic motor carried by the frame and associated with the platform section for moving the platform section on the frame;
- (d) at least one locking member fixedly attached to the frame to lock the frame to the building, the locking section being adjustable vertically and being moved during adjustment by means of a hydraulic cylinder and being locked in place by means of a pin, the locking section further comprising at least one screw jack positioned on top thereof and fixedly attached thereto;
- (e) a pair of rollers attached to one end of the frame for guiding the device within the building;
- and
- (f) a spreader bar pivotably mounted on the frame for lifting the device from floor to floor.
A method for moving construction material from one floor of a building under construction to another floor, comprising the steps of:
- (a) providing a removable construction device having a a movable platform formed therein and locking means for the device;
- (b) positioning the device on a predetermined floor with a lifting crane with a portion of the device being outside the building;
- (c) locking the device in place with the locking means;
- (d) moving the platform inside the building on the device;
- (e) loading the platform with the construction material to be relocated to a different floor;
- (f) moving the platform and the construction material outside of the building on the device;
- (g) picking up the construction material from the platform using the lifting crane and relocating it to a different floor;
- and
- (h) repeating steps (d) to (g) until all the desired construction material has been relocated.
