Abstract

PROBLEM TO BE SOLVED: To raise in the air at the load pick up place of a truck, not requiring a hang change by providing a gate shape framework for running on a rail in a shape striding the load pick up space of a truck and providing a hang up device on the horizontal beam of the gate shape framework. SOLUTION: By bringing up the one end of a member M placed horizontally on a truck carried by the truck T by a hoisting device 6 and hanging up the other end by a tower crane K, this device can be raised in the air. The gate shape framework 1 is moved horizontally in an arrow mark direction on a rail 5, following to the hanging up by the tower crane K so as to prevent an unreasonable lateral force. The hoisting device 6 provided on the gate shape framework 1 is supported to the horizontal beam 3 and laterally moved by a lateral running device 7 and coped with the adjustment by the stop position of the truck T and the case loaded plural members M. The raising device of the member by this gate shape framework can be utilized to the other load pick up device during the use of the tower crane and a horizontally moving device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for lifting vertically laid members such as steel columns, column prefabricated bars, and pile reinforced cages using a crane and vertically lifting them at a construction site or the like. The present invention relates to an erecting assisting device and an erecting method used in the present invention.

[0002]

2. Description of the Related Art In the case where one end of a horizontally placed member is simply erected and suspended, there are the following inconveniences as shown in FIGS.

When one end of the member M is lifted up by a crane K or the like in the direction of the arrow, the lower end MI of the member M may be deformed or damaged as shown in FIG.

Further, when the member M is lifted, there is a possibility that an excessive horizontal force F indicated by an arrow is applied to the crane K. G
Indicates the center of gravity.

When the member M is to be directly dropped from the truck T, the load may concentrate on the rear end T-1 of the truck and the truck T may fall.

[0006] For this reason, in general, an auxiliary crane is used to suspend the robot at two points and raise it in the air. However, according to this method, an installation place of the auxiliary crane and its cost are required.

Therefore, in a narrow place, as shown in FIGS. 6 and 7, a roller carriage R for the lower end and a hydraulic upright device J may be provided.

[0008]

When a member to be erected is placed horizontally on a truck or the like and transported, the member is once suspended horizontally, unloaded and placed on a device, and then suspended. It needs to be repositioned and lifted.
At that time, if there is only one tower crane or the like, time is required to change the hanging position, and the number of members handled per day decreases. In addition, since these devices are installed at a place different from the place where the truck is loaded, there is a problem in a small site.

Therefore, the present invention eliminates the need to suspend and change the position of a truck, and enables the truck to be erected in an aerial position at a place where the truck is to be loaded. The purpose of the present invention is to provide an erecting device and an erecting method.

[0010]

According to the present invention, there is provided an erecting apparatus used for erecting a horizontally laid member by using a crane to vertically lift the member, and the erecting device spans a loading space of a truck. , A portal frame running on a rail is provided, and a lifting device is provided on a horizontal girder of the portal frame.

Further, according to the present invention, the lifting device is supported by the horizontal girder of the portal frame and traversed by the traversing device.

Further, according to the present invention, there is provided an erecting apparatus used for erecting a horizontally laid member by using a crane and vertically lifting the member, the straddling space of a truck being straddled on a rail. A lifting device provided on a horizontal girder of a running portal frame lifts one end of a member that is transported by a truck and placed horizontally, lifts the other end with a crane, and raises the member in the air.

According to the present invention, the lifting device provided on the horizontal girder of the portal frame is traversed by the traversing device, and it is possible to cope with the adjustment by the stop position of the truck or the case where a plurality of members are stacked. I have.

[0014] It is not necessary to change the members to be erected, and it is also possible to erected in the air at a place where a truck is to be loaded, to save time and space, and to be applicable even in a very narrow place. Become.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a gate-shaped frame indicated generally by 1 is provided so as to straddle a loading space S of a truck. The portal frame 1 is composed of a pair of right and left vertical legs 2 connecting steel members in a triangle.
And a horizontal girder 3 connecting the vertical legs 2.
A traveling wheel 4 is attached to the vehicle and runs on a rail 5. A known brake device is attached to the traveling wheel 4.

The horizontal beam 3 is provided with a simple lifting device 6 such as an electric chain block, and the lifting device 6 is supported by the horizontal beam 3 by the traversing device 7 and traverses. Although not shown, the traveling wheels 4 of the frame 1 are provided with a well-known fall prevention device to prepare for an accidental fall.

Lifting one end of a horizontally placed member M on the truck conveyed by the truck T with the lifting device 6 and lifting the other end with a tower crane K or the like (not shown) to raise the member in the air. Can be.

As shown in FIG. 2, the gate-type frame 1 is horizontally moved on the rail 5 in the direction of the arrow as it is lifted by the tower crane K or the like so as to prevent excessive lateral force.

The lifting device 6 provided on the portal frame 1 traverses while being supported by the horizontal girder 3 by the traversing device 7 and copes with the adjustment by the stop position of the truck T and when a plurality of members M are stacked.

The erecting device for the members using the portal frame includes a loading device using a tower crane or the like,
It can also be used as a horizontal moving device.

The dimensions and shape of the portal frame are determined appropriately according to the target members and the conditions at the site.

[0023]

According to the present invention, there is no need to change the members, and it is possible to raise the truck in the air at a place where the truck is to be loaded. This saves time and space and is very narrow. Applicable in place.
