Description

  The present invention is used for climbing cranes that move up to a higher position as construction progresses, and covers the opening of the structure where the mast of the crane is installed from above, and rain falls on the opening. The present invention relates to a rain closing device for cranes that prevents the entry of the rain.

  As a crane, there is a type of crane called a climbing crane that is used for a high-rise structure and moves up to a higher position as work progresses. Explaining with reference to the drawings, in the initial assembly state, the telescopic base c is installed on the foundation floor b, and the crane body a is installed at the upper end of the mast d (FIG. 14A). In this state, a predetermined construction is performed, and when a predetermined process is completed, a bell receiving gantry f is installed on a higher floor, the crane body a is deposited (FIG. 14B), and then the elevator e is driven, The mast d is pushed up until the telescopic mount c reaches the planned floor (5F in FIG. 15A), the telescopic mount c is installed on the floor 5F (mast climbing), and the elevator e is driven to move the crane body a to the uppermost position. The process of creeping up to the floor PH1 (FIG. 15B: climbing of the crane body) is repeated.

  In the climbing crane, an opening g is formed in the structure because of the structure for installing the crane. When the structure is completed, the opening g becomes a part of the internal structure and is not exposed. However, the opening g remains exposed to perform crane climbing during the construction. Accordingly, during the construction period, since rain falls from the opening g to the inside of the structure, it is necessary to take some measures. Until now, drainage measures have been taken, but the conventional method requires the work of stretching a waterproof sheet under the floor and connecting it to the drainage route, and it must be carried out on each floor as construction progresses. There was a problem that it took a lot of work.

  Regarding the raining of the crane, there is a utility model registration No. 2570799. In the idea of the same issue, a tower crane mast opening curing unit consisting of a metal fitting to the circumference of the mast, an inverted umbrella-shaped bone frame, a sheet that forms an inverted umbrella together with the bone frame, and a drain connected to the inverted umbrella bottom. A device, a tent, is disclosed. However, with the structure that covers the opening from the bottom in this way, when the mast base is installed on the middle floor, the opening remains exposed from the floor to the top floor to prevent rain from being transferred. It is not possible. Further, when there is a structural beam or the like below the base, it is difficult to cover the opening itself from below. In addition, when the base is installed at the top of the climbing, if it covers the opening at the top, it will also be a measure against rain at lower floors.

Utility model registration No. 2570799

  The present invention has been made paying attention to the above points, and the problem is to prevent rainwater that falls from falling into the opening by covering the opening of the structure from above. Another object of the present invention is to enable a complete rain storm by installing the crane body at the top of the climb. Another object of the present invention is to provide a rain closing device for cranes that can cover the opening where the mast is installed from above on any floor, and completes the measures against rainfall for each floor. Is to provide.

  In order to solve the above-described problems, the present invention covers the opening of a structure in which a mast of a crane is installed from above, which is used for a climbing crane that is raised to a higher position as the construction progresses. The rain closing device that prevents the rain from falling into the opening has a size and shape that can cover the space inside the mast on which the main body of the crane is mounted, and is detachably mounted inside the mast. An umbrella body and an outer umbrella body arranged outside the mast and below the inner umbrella body so as to cover the opening and narrowed to a shape smaller than the opening are configured. This is a measure taken.

  The rain closing apparatus according to the present invention is used for climbing cranes, and in particular, covers an opening of a structure from above. A higher position such as the top floor is suitable for installing the rain closing device of the present invention, but it is not always possible to construct from the first to the top floor. Moreover, since it is meaningful to cover from above, the opening formed at an arbitrary height position as the construction progresses is the object.
