Description

  The present invention relates to a heavy load transport installation device, and more particularly to a heavy load transport installation device for transporting a heavy load along an upper flange of a main girder and installing it when a bridge superstructure is constructed.

  When building the superstructure of the bridge, after spanning the bridge girder, etc., various heavy objects, such as concrete formwork for building bridge decks, floor slab assembly materials such as reinforcing bars, or precast decks Etc. must be transported and installed.

  As a method of transporting and installing such heavy objects on the bridge girder, a method of directly installing on a bridge girder by a crane is common. For example, a steel formwork 1 for floor slab construction shown in FIG. 23 is composed of a plurality of divided bottom steel plates 2 and reinforcing steel materials 3 that connect these bottom steel plates 2 at regular intervals. The weight per panel is about 4 t.

  In order to lift and install the steel mold 1 with a crane, the crane 4 must be able to move to the vicinity of the installation location as shown in FIG. However, there are many cases where rivers, roads, etc. cross at the bridge point and cranes cannot be placed close to each other. In this case, as shown in FIG. Yes.

  As shown in FIG. 26, the bridge girder 5 comprises a main girder 6 parallel to the direction of the bridge axis and a horizontal girder 7 for connecting these main girder 6, and a concrete floor to be constructed on the upper flange 8 of the main girder 6. Welding steel rods 9 as stoppers for integration with the plate are provided at appropriate intervals. As shown in FIG. 27, the bottom steel plate 2 of the steel mold 1 is divided so as to be placed on the main girder 6 while avoiding the welded steel rod 9, and as shown in the sectional view of FIG. 3 is formed so that the welding steel rod 9 can be inserted into each gap at the installation location after conveyance.

It is equipped with a transport base for placing such heavy objects, a transport surface for supporting the transport base is formed on the upper flange upper surface of the main girder, and a heavy object hoisting / suspending unit for installing a heavy object at a predetermined position of the main girder As a conventional transfer installation apparatus provided with a lowering means, for example, there is a transfer installation apparatus as described in Patent Document 1 and Patent Document 2.
Japanese Patent No. 3666870 JP 2008-240347A

  The transfer installation device described in Patent Document 1 has a rail support means attached to the upper flange of a steel girder, and a single rail is supported above the upper flange by the rail support means, and the drive carriage and the drive carriage are supported on the single rail. It was configured to be able to run a loading cart towed by.

  In this configuration, for example, when transporting a steel formwork, as shown in FIGS. 29 and 30, a rail support column 111 having a tubular body at the bottom is inserted into the welded steel rod 9 of the upper flange 8 of the main girder 6. It is worn and the rail 112 is bridged over this to form a conveyance path. On the other hand, a transport carriage 113 is attached to the lower surface of the reinforcing steel material 3 of the steel mold 1, and the transport carriage 113 is mounted on a rail and pulled and conveyed.

  Moreover, the conveyance installation apparatus described in patent document 2 supports the heavy article on a main girder on a main girder via a slide stand, and conveys it while sliding on the main girder by a retractor. The sliding cradle has a configuration in which a sliding base is used in a portion in contact with the main girder upper surface.

  In this configuration, when the steel mold is transported, as shown in FIG. 31, a sliding cradle 114 having a long axis in the main girder axis direction is placed on the upper flange 8 of the main girder 6. The reinforcing steel material 3 of the steel mold 1 is loaded via the height adjusting member 115. The sliding pedestal 114 is provided with a guide surface 116 protruding in the pull-in direction, and is conveyed along a threaded stud 117 protruding from the upper flange 8.

  However, when transporting on the rails arranged on the conventional main girder, it was necessary to lay rail facilities over the entire length of the section for transporting heavy objects. Further, in the transport device using the rail, before transporting the heavy object and before suspending it from the main girder, the rail 112 and the transport carriage 113 arranged between the heavy object and the main girder as shown in FIG. In this case, it is necessary to lift and hold the heavy load by the heavy load lifting / lowering means 118.

  Also, when transporting with a flat transport surface on the upper flange upper surface of the main girder, if there are obstacles on the transport surface, it will be impossible to transport, so for example in the part where the sliding cradle passes Studs had to be retrofitted. Therefore, in such a transport device, after transporting heavy objects, it was necessary to install large welding equipment on the construction site and to erect the required welding steel rod to connect the floor slab concrete and the main girder. .

  Also in this transport apparatus, when a heavy object is suspended and installed, it is necessary to lift and hold the heavy object once in order to remove the sliding cradle and the like.

  The present invention was made to eliminate the above-mentioned problems of the conventional heavy load transport installation device, and does not require post-treatment such as a steel bar for securing a transport surface, and is a section for transport It is an object of the present invention to provide a heavy load transport installation device capable of simplifying transport facilities over the entire length.
